                                  INSTRUCTIONS
         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
 
    1.  GUARANTEE OF SIGNATURES.  All signatures on this Letter of Transmittal
must be guaranteed by a firm which is a financial institution (including most
commercial banks, savings and loan associations and brokerage houses) that is a
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Guarantee Program or the Stock Exchange
Medallion Program (each, an "Eligible Institution"), except in cases where
Universal Shares are tendered (i) by a registered holder of Universal Shares who
has not completed either the box entitled "Special Exchange Instructions" or the
box entitled "Special Delivery Instructions" on this Letter of Transmittal or
(ii) for the account of an Eligible Institution. If a Share Certificate is
registered in the name of a person other than the signatory of this Letter of
Transmittal, or if payment is to be made, or a Share Certificate not accepted
for exchange or not tendered is to be returned, to a person other than the
registered holder(s), then the Share Certificate must be endorsed or accompanied
by appropriate stock powers, in either case signed exactly as the name(s) of the
registered holder(s) appears on the Share Certificate, with the signature(s) on
such Share Certificate or stock powers guaranteed by an Eligible Institution.
See Instruction 5.
 
    2.  DELIVERY OF LETTER OF TRANSMITTAL AND UNIVERSAL SHARES.  This Letter of
Transmittal is to be used either if certificates are to be forwarded herewith or
if delivery of Universal Shares is to be made by book-entry transfer pursuant to
the procedures set forth in the section of the Proxy Statement/Prospectus
entitled "THE EXCHANGE OFFER--Procedures for Accepting the Exchange Offer and
Tendering Shares." Certificates for all physically delivered Universal Shares,
or a confirmation of a book-entry transfer into the Exchange Agent's account at
one of the Book-Entry Transfer Facilities of all Universal Shares delivered
electronically, as well as a properly completed and duly executed Letter of
Transmittal (or a facsimile thereof), or an Agent's Message in connection with a
book-entry delivery of Universal Shares, and any other documents required by
this Letter of Transmittal, must be received by the Exchange Agent at one of its
addresses set forth on the front page of this Letter of Transmittal by the
Expiration Date. If a shareholder desires to tender Universal Shares pursuant to
the Exchange Offer and such shareholder's Share Certificates evidencing such
Universal Shares are not immediately available or such shareholder cannot
deliver the Share Certificates and all other required documents to the Exchange
Agent prior to the Expiration Date, or such shareholder cannot complete the
procedure for delivery by book-entry transfer on a timely basis, such Universal
Shares may nevertheless be tendered pursuant to the guaranteed delivery
procedure set forth in the section of the Proxy Statement/Prospectus entitled
"THE EXCHANGE OFFER--Procedures for Accepting the Exchange Offer and Tendering
Shares." Pursuant to such procedure: (i) such tender must be made by or through
an Eligible Institution; (ii) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form made available by 99 CENTS Only
Stores, must be received by the Exchange Agent prior to the Expiration Date; and
(iii) the Share Certificates (or a book-entry confirmation) evidencing all
tendered Universal Shares, in proper form for transfer, in each case together
with the Letter of Transmittal (or a facsimile thereof), properly completed and
duly executed, with any required signature guarantees, or, in the case of a
book-entry transfer, an Agent's Message, and any other documents required by the
Letter of Transmittal must be received by the Exchange Agent within three New
York Stock Exchange trading days after the date of execution of such Notice of
Guaranteed Delivery.
 
    The term "Agent's Message" means a message transmitted by a Book-Entry
Transfer Facility to, and received by, the Exchange Agent and forming a part of
a book-entry confirmation, which states that such Book-Entry Transfer Facility
has received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Universal Shares that such participant has
received and agrees to be bound by the terms of the Letter of Transmittal and
that 99 CENTS Only Stores may enforce such agreement against such participant.
 
    THE METHOD OF DELIVERY OF UNIVERSAL SHARES AND ALL OTHER REQUIRED DOCUMENTS,
INCLUDING THROUGH ANY BOOK-ENTRY TRANSFER FACILITY, IS AT THE OPTION AND SOLE
RISK OF THE TENDERING HOLDER OF UNIVERSAL SHARES AND THE DELIVERY WILL BE DEEMED
MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
SHAREHOLDERS WHOSE UNIVERSAL SHARES ARE REGISTERED IN THE NAME OF A BROKER,
INVESTMENT DEALER, BANK, TRUST COMPANY OR OTHER NOMINEE SHOULD CONTACT THAT
NOMINEE FOR ASSISTANCE IN TENDERING THOSE UNIVERSAL SHARES.
 
    No alternative, conditional or contingent tenders will be accepted, and no
fractional Universal Shares will be exchanged. By executing this Letter of
Transmittal (or a facsimile hereof), the tendering holder of Universal Shares
waives any right to receive any notice of the acceptance for exchange of the
Universal Shares.
 
    3.  INADEQUATE SPACE.  If the space provided herein is inadequate, the
certificate numbers and/or the number of Universal Shares and any other required
information should be listed on a separate signed schedule which is attached to
this Letter of Transmittal.

    4.  PARTIAL TENDERS (NOT APPLICABLE TO HOLDERS OF UNIVERSAL SHARES WHO
TENDER BY BOOK-ENTRY TRANSFER).  If fewer than all the Universal Shares
represented by any certificate delivered to the Exchange Agent are to be
tendered, fill in the number of Universal Shares which are to be tendered in the
box entitled "Number of Universal Shares Tendered." In such case, a new
certificate for the remainder of the Universal Shares represented by the old
certificate will be sent to the person(s) signing this Letter of Transmittal,
unless otherwise provided in the appropriate box on this Letter of Transmittal,
as promptly as practicable following the expiration or termination of the
Exchange Offer. All Universal Shares represented by certificates delivered to
the Exchange Agent will be deemed to have been tendered unless otherwise
indicated.
 
    5.  SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS.  If
this Letter of Transmittal is signed by the registered holder(s) of the
Universal Shares tendered hereby, the signature(s) must correspond with the
name(s) as written on the face of the certificates representing such Universal
Shares without any alteration or change whatsoever.
 
    If any of the Universal Shares tendered hereby are held of record by two or
more persons, all such persons must sign this Letter of Transmittal.
 
    If any of the Universal Shares tendered hereby are registered in different
names on different certificates, it will be necessary to complete, sign and
submit as many separate Letters of Transmittal as there are different
registration of certificates.
 
    If this Letter of Transmittal is signed by the registered holder(s) of the
Universal Shares tendered hereby, no endorsements of certificates or separate
stock powers are required unless certificates for shares of 99 CENTS Only Stores
Common Stock or any checks for any cash payment in lieu of fractional shares of
99 CENTS Only Stores Common Stock are issued, or Universal Shares not tendered
or not accepted for exchange are to be returned, in the name of any person other
than the registered holder(s). Signatures on any such certificates or stock
powers must be guaranteed by an Eligible Institution.
 
    If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Universal Shares tendered hereby, certificates must
be endorsed or accompanied by stock powers, in either case, signed exactly as
the name(s) of the registered holder(s) appear(s) on the certificates for such
Universal Shares. Signature(s) on any such certificates or stock powers must be
guaranteed by an Eligible Institution.
 
    If this Letter of Transmittal or any certificate or stock power is signed by
a trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory to
99 CENTS Only Stores of the authority of such person to act must be submitted.
 
    6.  STOCK TRANSFER TAXES.  Any stock transfer taxes with respect to the
exchange and transfer of any Universal Shares to 99 CENTS Only Stores or its
order pursuant to the Exchange Offer will be paid by or on behalf of 99 CENTS
Only Stores. If, however, certificates for shares of 99 CENTS Only Stores Common
Stock or any checks for any cash payment in lieu of fractional shares of
99 CENTS Only Stores Common Stock are issued, or Universal Shares not tendered
or not accepted for exchange are to be returned, in the name of any person other
than the registered holder(s), the amount of any stock transfer taxes (whether
imposed on the registered holder(s), such other person or otherwise) payable on
account of the transfer to such person will be deducted from the consideration
to be received by such holder unless satisfactory evidence of the payment of
such taxes, or exception therefrom, is submitted.
 
    7.  SPECIAL EXCHANGE AND DELIVERY INSTRUCTIONS.  If the certificates for
shares of 99 CENTS Only Stores Common Stock or any checks for any cash payment
in lieu of payment of fractional shares of 99 CENTS Only Stores Common Stock are
to be issued, or any Universal Shares not tendered or not accepted for exchange
are to be returned, in the name of a person other than the person(s) signing
this Letter of Transmittal or if the certificates for shares of 99 CENTS Only
Stores Common Stock, or any checks for any cash payment in lieu of fractional
shares of 99 CENTS Only Stores Common Stock or any certificates for Universal
Shares not tendered or not accepted for exchange are to be mailed to someone
other than the person(s) signing this Letter of Transmittal or to the person(s)
signing this Letter of Transmittal at an address other than that shown above,
the appropriate boxes on this Letter of Transmittal should be completed.
 
    8.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions and requests
for assistance may be directed to the Information Agent or the Dealer Manager at
their respective addresses and telephone numbers listed below. Additional copies
of the Proxy Statement/Prospectus, the Letter of Transmittal and other exchange
offer materials may be obtained from the Information Agent as set forth below.
You may also contact your broker, dealer, commercial bank, trust company or
other nominee, as applicable, for assistance concerning the Exchange Offer.
 
    9.  SUBSTITUTE FORM W-9.  Under U.S. federal income tax law, a holder of
Universal Shares whose Universal Shares are accepted for exchange is required to
provide the Exchange Agent with such holder's correct taxpayer identification
number ("TIN") on the Substitute Form W-9 set forth below. If the Exchange Agent
is not provided

with the correct TIN, the Internal Revenue Service may subject the holder or
other payee to a $50.00 penalty. In addition, payments that are made to such
holder or other payee with respect to Universal Shares exchanged in the Exchange
Offer may be subject to 31% backup withholding.
 
    Certain holders of Universal Shares (including among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. In order for a foreign individual to
qualify as an exempt recipient, the holder of Universal Shares must submit a
Form W-8, signed under penalties of perjury, attesting to that individual's
exempt status. A Form W-8 may be obtained from the Exchange Agent. See the
enclosed "Guidelines For Certification of Taxpayer Identification Number On
Substitute Form W-9" for more instructions.
 
    If backup withholding applies, the Exchange Agent is required to withhold
31% of any such payments made to the holder of Universal Shares or other payee.
Backup withholding is not an additional tax. Rather, the 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 box in Part 3 of the Substitute Form W-9 should be checked if the
tendering holder of Universal Shares has not been issued a TIN and has applied
for a TIN or intends to apply for a TIN in the near future. If the box in Part 3
is checked, the holder of Universal Shares or other payee must also complete the
Certificate of Awaiting Taxpayer Identification Number below in order to avoid
backup withholding. Notwithstanding that the box in Part 3 is checked and the
Certificate of Awaiting Taxpayer Identification Number is completed, the
Exchange Agent will withhold 31% of all payments made prior to the time a
properly certified TIN is provided to the Exchange Agent.
 
    The holder of Universal Shares is required to give the Exchange Agent the
TIN (E.G., social security number or employer identification number) of the
record owner of the Universal Shares or of the last transferee appearing on the
transfers attached to, or endorsed on, the Universal Shares. If the Universal
Shares are in more than one name or are not in the name of the actual owner,
consult the enclosed "Guidelines For Certification of Taxpayer Identification
Number on Substitute Form W-9" for additional guidance as to which number to
report.
 
    10.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate(s)
representing Universal Shares has been lost, destroyed or stolen, the
shareholder should promptly notify the Exchange Agent. The shareholder will then
be instructed as to the steps that must be taken in order to replace the
certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost or destroyed certificates have
been followed.
 
    11.  WAIVER OF CONDITIONS.  Subject to the terms of the Exchange Offer,
99 CENTS Only Stores reserves the absolute right in its sole discretion to waive
any of the specified conditions of the Exchange Offer, in whole or in part, in
the case of any Universal Shares tendered.
 
    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY HEREOF) OR AN
AGENT'S MESSAGE TOGETHER WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY
TRANSFER OR A PROPERLY COMPLETED AND DULY EXECUTED NOTICE OF GUARANTEED DELIVERY

                                  (2)  I am not subject to backup withholding because: (a) I am
                                  exempt from backup withholding, or (b) I have not been notified
                                       by the Internal Revenue Service (the "IRS") that I am
                                       subject to backup withholding as a result of a failure to

                                       notified me that I am no longer subject to backup

                                  you were subject to backup withholding you received another
                                  notification from the IRS that you are no longer subject to
                                  backup withholding, do not cross out item (2).
