Leslie D. Goldberg....................  57
Jerome S. Traum.......................  64
Howard M. Brenner.....................  66


     Leslie D. Goldberg served as President of Interep from August 1986 to the
end of 1995, and has served as a director of Interep since 1986.  He has been
employed by Interep since 1968 in various capacities.  Mr. Goldberg serves on
the Board of Directors of the Radio Advertising Bureau.

has been a partner with the New York law firm of Moses & Singer since June 1995.
Before that, he was of counsel to the New York law firm of Proskauer Rose Goetz

Blackstone Group, an investment banking firm.

     Howard M. Brenner has served as a director of Interep since December 1999.

Section 16(a) Beneficial Ownership Reporting Compliance

     Section 16(a) of the Securities Exchange Act of 1934 requires our executive
officers and directors, and persons who own more than 10% of our common stock,
to file with the Commission initial statements of beneficial ownership and
statements of changes in beneficial ownership of our common stock on Forms 3, 4
and 5, and to furnish us with copies of all such forms they file.  Based on a
review of the copies of such forms furnished to us, we believe that all of our
officers, directors and greater than 10% beneficial owners filed all such forms
which were required to be filed during 1999.  However, the initial statements on
Form 3 required to be filed by each of such persons and entities, Ralph C.
Guild, Marc G. Guild, William J. McEntee, Jr., Leslie D. Goldberg, Jerome S.
Traum, Stewart Yaguda, Charles Parra and Howard M. Brenner, our Employee Stock
Ownership Plan and Trust and our Stock Growth Plan and Trust, were filed later
than 10 days after the consummation of our initial public offering.

     Interep's Board of Directors established an Audit Committee and a

principles to be used by Interep in financial reporting, Interep's internal
financial auditing procedures and the adequacy of Interep's internal control
procedures.  The Compensation Committee determines officers' salaries and
bonuses, and administers Interep's Stock Option Plan.  The members of each of
the Audit Committee and the Compensation Committee are Jerome Traum and Howard
Brenner.

Director Compensation

     Each director who is not an employee is entitled to a fee of $1,000 for
each day of attendance at any meeting of the Board of Directors or any committee
thereof, plus reimbursement of related reasonable out-of-pocket expenses.  Other

reimbursed for any reasonable out-of-pocket expenses incurred in connection with
attending such meetings.

Employment Contracts

     Ralph Guild is employed as our Chairman of the Board and Chief Executive
Officer under an employment agreement. The term of this agreement runs through
February 29, 2005 and is automatically extended for an additional year each
March 1 unless either we or Ralph Guild notifies the other on or before February
1 of the same year of our or his election not to extend the agreement. Ralph
Guild receives a base salary of not less than $925,000 per year, plus any bonus,
incentive or other types of additional compensation which our Board of Directors
determines to pay. Further, he is entitled to receive annual incentive
compensation based on increases in our Adjusted EBITDA. If Adjusted EBITDA for
any year is greater than the Adjusted EBITDA for the previous year, Ralph Guild
will be entitled to a bonus equal to a percentage of his base salary equal to
two times the percentage increase of Adjusted EBITDA for such year over the
higher of Adjusted EBITDA for the prior year and the highest Adjusted EBITDA for
any prior year back to 1998. If we elect not to extend the term of the
agreement, we are required to retain Ralph Guild as a consultant for an
additional two years at a fee equal to his base salary in effect at such time.

     The agreement provides for continued payment of Ralph Guild's base salary
through the balance of its term, plus two years, if (i) Ralph Guild terminates
his employment with us by reason of our material breach of the agreement, (ii)
Ralph Guild is not re-appointed as Chairman of the Board and Chief Executive
Officer or ceases to be elected as a director, other than by his own choice or
for reasons justifying termination of his employment by us for cause, or (iii)
there is a change in control of our Board of Directors. Ralph Guild may not
compete with us during the term of the employment agreement and thereafter for
as long as he is receiving compensation under the agreement. The agreement also
provides (i) in the case of Ralph Guild's permanent disability, for payments to
Ralph Guild equal to 75% of his then current salary, less any income disability
benefits to which he may be entitled, for the balance of his employment term and
(ii) in the case of Ralph Guild's death, at the option of his estate or his
designated beneficiary, for a death benefit equal to either the present value at
the time of his death of the entire amount of the salary that would have been
payable to him for the balance of his employment term or the payment of his then
current salary over the balance of his employment term.



                                       4
<PAGE>

     Ralph Guild also has a supplemental income agreement pursuant to which we
pay him $104,583 per year, payable in monthly installments, through 2008. We
maintain a whole life insurance policy on Ralph Guild for the purpose of funding
the supplemental income agreement.

     Marc Guild is employed as our President, Marketing Division under an
employment agreement. The term of this agreement runs through January 1, 2002
and is automatically extended for an additional year each January 1 unless
either we or Marc Guild notifies the other on or before December 1 of the
preceding year of our or his election not to extend the agreement. Under the
agreement, Marc Guild receives a base annual salary of $360,000 and an incentive
amount of $90,000 per year, which is payable by us only if we achieve certain
financial or other goals set by Marc Guild and us at the beginning of each year.
The agreement provides for continued payments of base salary through the balance
of its term if (i) there is a change in control of our company, (ii) Marc Guild
is not re-appointed to his office with us or ceases to be a director, other than
by reason of his own choice or the termination of his employment for cause or
(iii) Marc Guild's termination of his employment by reason of a material breach
by us of the agreement. The agreement also provides (i) in the case of Marc
Guild's permanent disability, for payments to him equal to 75% of his then
current salary, less any income disability benefits that he may receive or to
which he may be entitled, for the duration of the term of the agreement and (ii)
in the case of Marc Guild's death, at the option of his estate or his designated
beneficiary, for a death benefit equal to the present value at the time of death
of the entire amount of the salary that would have been payable to him for the
balance of his employment term or the payment of his then current salary over
the balance of his employment term.

Indemnification Agreements

     We are a party to an indemnification agreement with each of our directors
and certain of our executive officers. These agreements entitle these persons to
be indemnified, which may include advancement of expenses, to the fullest extent
permitted by law for all expenses, judgments, fines, penalties and settlement
payments incurred by an indemnitee in actions brought against him or her in
connection with any act taken in his or her capacity as a director or executive
officer. Under these agreements, each decision as to indemnification will be
made by a majority of the disinterested members of our Board of Directors, if
such members constitute a quorum of the full Board, or otherwise by independent
legal counsel selected by our Board.

Compensation Committee Interlocks and Insider Participation

     For the fiscal year ended December 31, 1999, the entire Board of Directors
determined executive officer compensation. Two members of the Board of
Directors, Ralph Guild and Marc Guild, are officers of Interep, and have
participated in certain transactions with Interep during 1998. See Item 13.

Performance Graph

     The Commission requires us to present a chart comparing the cumulative
stockholder return on the common stock with the cumulative shareholder return of
a broad equity market index, such as the Standard & Poor's 500 Stock Index and
either a nationally-recognized industry standard or a group of peer companies
selected by the Company. The Company has selected, for purposes of this
performance comparison, the Standard & Poor's Broadcasting (TV, Radio and Cable)
Index. The graph assumes that $100 was invested on December 9, 1999 (the date on
which the Class A common stock began trading) in the Class A common stock,
that $100 was invested on November 30, 1999 (the date closest to December 9,
1999 for which data is available) in the S&P 500 Index and the S&P Broadcasting
(TV, Radio & Cable) Index, and that all dividends were reinvested.

Item 12.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

     The following table sets forth certain information concerning the
beneficial ownership of our common stock held on April 15, 2000 by (i) each
person known to us to own beneficially more than 5% of the common stock, (ii)
each of our directors, (iii) each of our executive officers and (iv) all
directors and executive officers as a group.

     The number and percentage of shares beneficially owned are determined in
accordance with Rule 13d-3 of the Securities Exchange Act of 1934, and the
information is not necessarily indicative of beneficial ownership for any other
purpose. Shares of common stock subject to options that are currently
exercisable, or exercisable within 60 days of April 15, 2000, are deemed to be
beneficially owned by the person holding the options for the purpose of
computing that person's percentage ownership, but are not treated as outstanding
for the purpose of computing the percentage ownership of any other person.
Unless otherwise indicated in the footnotes, each person or entity has sole
voting and investment power (or shares these powers with his or her spouse) with
respect to the shares shown as beneficially owned.

     As of April 15, 2000, there was 6,241,890 shares of Class A common stock
and 4,098,739 shares of Class B common stock outstanding. Only qualified
holders, that is, members of our Board of Directors, our active employees, the
controlled affiliates, spouses, estates or personal representatives of directors
and employees, and our employee benefit plans, including the ESOP and the Stock
Growth Plan, may hold Class B common stock. Each share of Class B Common Stock
is convertible into one share of Class A Common Stock at the option of the
holder or automatically under certain circumstances. Each share of the Class B
Common Stock is entitled to 10 votes per share in all matters presented to the
shareholders, except for certain amendments to the Restated Certificate of
Incorporation, certain "going private" transactions and as otherwise required by
applicable law. The shares of Class A Common Stock are entitled to one vote per
share on all matters.

Item 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Pursuant to a services agreement between Interep and Media Financial
Services, Inc. ("Media"), Interep retained Media, for a five-year term
commencing June 1, 1997, to provide certain financial and accounting services
for Interep and its subsidiaries. These services include the preparation of
monthly, quarterly and annual financial statements, the preparation and filing
of all required federal, state and local tax returns and all billing, accounts
receivable, accounts payable and collections functions. Under the services
agreement, Mr. McEntee, who is the President of Media and its sole stockholder,
is in charge of all services rendered by Media to Interep and also serves as
Vice President and Chief Financial Officer of Interep for an annual salary of
$120,000. For its services, Media was paid fees of approximately $1.4 million
in 1997, $2.6 million in 1998 and $3 million in 1999. Its annual fees for 2000,
2001 and the first five months of 2002 will be approximately $3 million, $3.1
million and $1.3 million, respectively.

     Since December 1979, Interep has leased a building from a trust of which
Ralph Guild is the income beneficiary, Marc Guild is the trustee and Marc Guild,
Adam Guild and their siblings are residual beneficiaries. We use the building
from time to time for training sessions and management meetings. The lease
expires on December 31, 2009 and provides for base annual rentals increasing
from $78,000 per year to $102,000 per year over the term of the lease, subject
to adjustment for actual usage. In each of 1996, 1997 and 1998 total lease
expense was $74,000. Interep also leases an apartment in New York City from a
partnership of which Marc Guild, Adam Guild and their siblings are limited
partners. The apartment is for the use of visiting Interep employees, including
Ralph Guild, when they are working in the New York office. The lease expires on
January 31, 2009 and provides for annual rent of $120,000, subject to increase
for up to 50% of any increases in applicable real estate taxes and common
charges. Interep believes the terms of these lease arrangements are at least
comparable to, if not more favorable to Interep than, the terms which would have
been obtained in transactions with unrelated parties. Interep intends to
continue these or other arrangements in the future as long as it believes each
transaction is more beneficial to Interep than using an unrelated provider. Adam
Guild and Phillip Brown, who are Ralph Guild's son and son-in-law,
respectively, are also employees.

     In June 1998, we disposed of our non-radio rep firm subsidiary, Corporate
Family Network, Inc., or CFN. The results of operations of CFN had resulted in
immaterial losses since its inception. We sold CFN to Ralph Guild for a purchase
price of $200,000, which was our estimate of the net fair market value of CFN,
payable $50,000 in cash and $150,000 by execution and delivery by Mr. Guild of a
promissory note payable in three annual installments of $50,000 each and bearing
interest at a fluctuating rate equal to the prime rate of BankBoston, N.A., plus
one percent.
