  The undersigned acknowledges receipt of the Prospectus dated [     ], 1999
(the "Prospectus"), of Interep National Radio Sales, Inc., a New York
corporation (the "Company"), and this Letter of Transmittal (the "Letter of
Transmittal"), which together with the Prospectus constitutes the Company's
offer (the "Exchange Offer") to exchange $1,000 principal amount of its 10%
Senior Subordinated Notes due 2008, Series B (the "Exchange Notes ") for each
$1,000 principal amount of its outstanding 10% Senior Subordinated Notes due
2008, Series A (the "Private Notes"). Recipients of the Prospectus should read
the requirements described in the Prospectus with respect to eligibility to
participate in the Exchange Offer. Capitalized terms used but not defined
herein have the meanings given to them in the Prospectus.
 
  The undersigned hereby tenders the Private Notes described in the box
entitled "Description of Private Notes" below pursuant to the terms and
conditions described in the Prospectus and this Letter of Transmittal. The
undersigned is the registered owner of all such Private Notes and the
undersigned represents that it has received from each beneficial owner of such
Private Notes other than itself ("Beneficial Owners") a duly completed and
executed form of "Instruction to Registered Holder from Beneficial Owner"
(which accompanies this Letter of Transmittal), instructing the undersigned to
take the action described in this Letter of Transmittal.
 
  This Letter of Transmittal is to be used by a holder of Private Notes (i) if
certificates representing Private Notes are to be forwarded herewith; (ii) if
delivery of Private Notes is to be made by book-entry transfer to the Exchange
Agent's account at The Depository Trust Company ("DTC"), pursuant to the
procedures set forth in the section of the Prospectus entitled "The Exchange
Offer--Procedures for Tendering," or (iii) if a tender is made pursuant to the
guaranteed delivery procedures in the section of the Prospectus entitled "The
Exchange Offer--Guaranteed Delivery Procedures."
 
  The undersigned hereby represents and warrants that the information received
from beneficial owners is accurately reflected in the boxes entitled
"Beneficial Owner(s)--Purchaser Status" and "Beneficial Owner(s)-- Residence."
 
  Any beneficial owner whose Private Notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender them should contact such registered holder promptly and instruct
such registered holder to tender on behalf of the beneficial owner. If such
beneficial owner wishes to tender on its own behalf, such beneficial owner
must, prior to completing and executing this Letter of Transmittal and
delivering its Private Notes, either make appropriate arrangements to register
ownership of the Private Notes in such beneficial owner's name or obtain a
properly completed bond power from the registered holder. The transfer of
record ownership may take considerable time.
 
  In order to properly complete this Letter of Transmittal, a holder of
Private Notes must (i) complete the box entitled "Description of Private
Notes;" (ii) complete the boxes entitled "Beneficial Owner(s)--Purchaser
Status" and "Beneficial Owner(s)--Residence;" (iii) if appropriate, check and
complete the boxes relating to book-entry transfer, guaranteed delivery,
Special Issuance Instructions and Special Delivery Instructions; (iv) sign the
Letter of Transmittal by completing the box entitled "Sign Here" and (v)
complete the Substitute Form W-9. Each holder of Private Notes should
carefully read the detailed instructions below prior to completing the Letter
of Transmittal.
 
  Holders of Private Notes who desire to tender their Private Notes for
exchange and (i) whose Private Notes are not immediately available or (ii) who
cannot deliver to the Exchange Agent their Private Notes, this Letter of
Transmittal and all other documents required hereby on or prior to the
Expiration Date, must tender the Private Notes pursuant to the guaranteed
delivery procedures set forth in the section of the Prospectus entitled "The
Exchange Offer--Guaranteed Delivery Procedures." See Instruction 2.
 
  Holders of Private Notes who wish to tender their Private Notes for exchange
must complete columns (1) through (3) in the box below entitled "Description
of Private Notes," complete the boxes entitled and sign the box below entitled
"'Sign Here." If only those columns are completed, such holder of Private
Notes will have tendered for exchange all Private Notes listed in column (3)
below. If the holder of Private Notes wishes to tender for exchange less than
all of such Private Notes, column (4) must be completed in full. In such case,
such holder of Private Notes should refer to Instruction 5.

undersigned hereby tenders to the Company for exchange the Private Notes
indicated above.
 
  By executing this Letter of Transmittal and subject to and effective upon
acceptance for exchange of the Private Notes tendered for exchange herewith,
the undersigned will have irrevocably sold, assigned, transferred and
exchanged, to the Company, all right, title and interest in, to and under all
of the Private Notes tendered for exchange hereby, and hereby will have
appointed the Exchange Agent as the true and lawful agent and attorney-in-fact
(with full knowledge that the Exchange Agent also acts as agent of the
Company) of such holder of Private Notes with respect to such Private Notes

Private Notes, or transfer ownership of such Private Notes on the account
books maintained by DTC (together, in any such case, with all accompanying
evidences of transfer and authenticity), to the Company, (ii) present and

instructions hereto will constitute a binding agreement between the
undersigned and the Company upon the terms and subject to the conditions of

"Special Issuance Instructions" and "Special Delivery Instructions" to
transfer any Private Notes from the name of the holder of Private Note(s)
thereof if the Company does not accept for exchange any of the Private Notes
so tendered for exchange or if such transfer would not be in compliance with
any transfer restrictions applicable to such Private Note(s).

Notes must complete, execute and deliver this Letter of Transmittal.

  No alternative, conditional or contingent tenders will be accepted. All
tendering holders of Private Notes, by execution of this Letter of Transmittal
(or facsimile hereof, if applicable), waive any right to receive notice of the
acceptance of their Private Notes for exchange.
 
  3.Inadequate Space. If the space provided in the box entitled "Description
of Private Notes" above is inadequate, the certificate numbers and principal
amounts of the Private Notes being tendered should be listed on a separate
signed schedule affixed hereto.
 
  4. Withdrawals. A tender of Private Notes may be withdrawn at any time prior
to 5:00 p.m., New York City time, on the Expiration Date, by delivery of a
written or facsimile notice of withdrawal to the Exchange Agent at the address
set forth on the cover of this Letter of Transmittal. To be effective, a
notice of withdrawal of Private Notes must (i) specify the name of the person
who tendered the Private Notes to be withdrawn (the "Depositor"); (ii)
identify the Private Notes to be withdrawn (including the certificate number
or numbers and aggregate principal amount of such Private Notes); and (iii) be
signed by the holder of Private Notes that were tendered (including any
required signature guarantees). All questions as to the validity, form and
eligibility (including time of receipt) of such notices will be determined by
the Company in its sole discretion, whose determination shall be final and
binding on all parties. Any Private Notes so withdrawn will thereafter be
deemed not validly tendered for purposes of the Exchange Offer and no Exchange
Notes will be issued with respect thereto unless the Private Notes so
withdrawn are validly retendered. Properly withdrawn Private Notes may be
retendered by following one of the procedures described in the section of the
Prospectus entitled "The Exchange Offer--Procedures for Tendering" at any time
prior to 5:00 p.m., New York City time, on the Expiration Date.
 
  5. Partial Tenders. Tenders of Private Notes will be accepted only in
integral multiples of $1,000 principal amount. If a tender for exchange is to
be made with respect to less than the entire principal amount of any Private
Notes, fill in the principal amount of Private Notes which are tendered for
exchange in column (4) of the box entitled "Description of Private Notes," as
more fully described in the footnotes thereto. In case of a partial tender for
exchange, a new certificate, in fully registered form, for the remainder of
the principal amount of the Private Notes, will be sent to the holders of
Private Notes unless otherwise indicated in the appropriate box on this Letter
of Transmittal as promptly as practicable after the expiration or termination
of the Exchange Offer.

Transmittal must correspond with the name(s) as written on the face of the
Private Notes without alternation, enlargement or any change whatsoever.
 
  (b) If tendered Private Notes are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal.

many separate copies of this Letter of Transmittal and any necessary or
required documents as there are different registrations or certificates.
 
  (d) When this Letter of Transmittal is signed by the holder of the Private
Notes listed and transmitted hereby, no endorsements of Private Notes or bond
powers are required. If, however, Private Notes not tendered or not accepted,
are to be issued or returned in the name of a person other than the holder of
Private Notes, then the Private Notes transmitted hereby must be endorsed or
accompanied by a properly completed bond power, in a form satisfactory to the
Company, in either case signed exactly as the name(s) of the holder of Private
Notes appear(s) on the Private Notes. Signatures on such Private Notes or bond
powers must be guaranteed by an Eligible Institution (unless signed by an
Eligible Institution).
 
  (e) If this Letter of Transmittal or Private Notes or bond powers are signed

of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing, and unless waived by this
Company, evidence satisfactory to the Company of their authority to so act
must be submitted with this Letter of Transmittal.

  7.Transfer Taxes. Except as set forth in this Instruction 7, the Company
will pay all transfer taxes, if any, applicable to the exchange of Private
Notes pursuant to the Exchange Offer. If, however, a transfer tax is imposed
for any reason other than the exchange of the Private Notes pursuant to the
Exchange Offer, then the amount of any such transfer taxes (whether imposed on
the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemptions
therefrom is not submitted with this Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering holder.
 
  8.Special Issuance and Delivery Instructions. If the Exchange Notes are to
be issued, or if any Private Notes not tendered for exchange are to be issued
or sent to someone other than the holder of Private Notes or to an address
other than that shown above, the appropriate boxes on this Letter of
Transmittal should be completed. Holders of Private Notes tendering Private
Notes by book-entry transfer may request that Private Notes not accepted be
credited to such account maintained at DTC as such holder of Private Notes may
designate.
 
  9.Irregularities. All questions as to the validity, form, eligibility
(including time of receipt), compliance with conditions, acceptance and
withdrawal of tendered Private Notes will be determined by the Company in its
sole discretion, which determination will be final and binding. The Company
reserves the absolute right to reject any and all Private Notes not properly
tendered or any Private Notes the Company's acceptance of which would, in the
opinion of counsel for the Company, be unlawful. The Company also reserves the
right to waive any defects, irregularities or conditions of tender as to
particular Private Notes. The Company's interpretation of the terms and
conditions of the Exchange Offer (including the instructions in the Letter of
Transmittal) will be final and binding on all parties. Unless waived, any

cured with such time as the Company shall determine. Although the Company
intends to notify holders of defects or irregularities with respect to tenders
of Private Notes, neither the Company, the Exchange Agent nor any other person
shall incur any liability for failure to give such notification. Tenders of
Private Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Private Notes received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders, unless otherwise provided in this Letter of
Transmittal, as soon as practicable following the Expiration Date.
 
  10.Waiver of Conditions. The Company reserves the absolute right to waive,
amend or modify certain of the specified conditions described under "The

                           IMPORTANT TAX INFORMATION
 
  Under current federal income tax law, a holder of Private Notes whose
tendered Private Notes are accepted for exchange may be subject to backup
withholding unless the holder provides the Company (as payor), through the
Exchange Agent, with either (i) such holder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 attached hereto, certifying that the TIN
provided on Substitute Form W-9 is correct (or that such holder of Private
Notes is awaiting a TIN) and that (A) the holder of Private Notes has not been
notified by the Internal Revenue Service that he or she is subject to backup
withholding as a result of a failure to report all interest or dividends or
(B) the Internal Revenue Service has notified the holder of Private Notes that
he or she is no longer subject to backup withholding; or (ii) an adequate
basis for exemption from backup withholding. If such holder of Private Notes
is an individual, the TIN is such holder's social security number. If the
Exchange Agent is not provided with the correct taxpayer identification
number, the holder of Private Notes may be subject to certain penalties
imposed by the Internal Revenue Service.
 
  Certain holders of Private Notes (including, among others, all corporations
and certain foreign individuals) are not subject to these backup withholding
and reporting requirements. Exempt holders of Private Notes should indicate
their exempt status on Substitute Form W-9. A foreign individual may qualify
as an exempt recipient by submitting to the Exchange Agent a properly
completed Internal Revenue Service Form W-8 (which the Exchange Agent will
provide upon request) signed under penalty of perjury, attesting to the
holder's exempt status. See the enclosed Guidelines of Certification of
Taxpayer Identification Number on Substitute Form W-9 (the "Guidelines") for
additional instructions.
 
  If backup withholding applies, the Company is required to withhold 31% of
any payment made to the holder of Private Notes or other payee. Backup
withholding is not an additional federal income tax. Rather, the federal
income tax liability of persons subject to backup withholding will be reduced
by the amount of tax withheld. If withholding results in an overpayment of
taxes, a refund may be obtained from the Internal Revenue Service.
 
  The holder of Private Notes is required to give the Exchange Agent the TIN
(e.g., social security number or employer identification number) or the record
owner of the Private Notes. If the Private Notes are held in more than one
name or are not held in the name of the actual owner, consult the enclosed
Guidelines for additional guidance regarding which number to report.
