                             PrimeSource Corporation
                                       at

                          Fuji Photo Film U.S.A., Inc.


         FPF Acquisition Corp., a Pennsylvania corporation ("Purchaser") and a
wholly-owned subsidiary of Enovation Graphic Systems, Inc., a Delaware
corporation ("EGS"), which is a wholly-owned subsidiary of Fuji Photo Film
U.S.A., Inc., a New York corporation ("Fuji"), which is an indirect wholly-owned
subsidiary of Fuji Photo Film Co., Ltd., a Japanese corporation, is offering to
purchase all outstanding shares of common stock, par value $0.01 per share, of
PrimeSource Corporation, a Pennsylvania corporation (the "Company"), including
the associated rights to purchase shares issued pursuant to the Rights Agreement
between the Company and American Stock Transfer & Trust Company, as Rights
Agent, dated as of February 1, 2001 (together, the "Shares"), at $10.00 per
Share, net to the seller in cash, without interest thereon, upon the terms and
subject to the conditions set forth in the Offer to Purchase and in the related
Letter of Transmittal (which, together with any amendments or supplements
thereto, collectively constitute the "Offer").

- --------------------------------------------------------------------------------
  The Offer and Withdrawal Rights will expire at 12:00 midnight, New York City
        time, on Tuesday, October 9, 2001, unless the Offer is extended.
- --------------------------------------------------------------------------------

         The Offer is conditioned upon, among other things, (1) there being
validly tendered and not withdrawn prior to the expiration of the Offer a number
of Shares that represents, together with any shares beneficially owned by Fuji
or Purchaser, at least 80% of the then outstanding Shares and (2) the expiration
or termination of the applicable waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976. The offer is also subject to other
conditions.

         The Offer is being made pursuant to the Agreement and Plan of Merger,
dated as of September 4, 2001 (the "Merger Agreement"), among Purchaser, EGS,
Fuji and the Company. The purpose of the Offer is to acquire control of, and the
entire equity interest in, the Company. The Merger Agreement provides that,
among other things, Purchaser will make the Offer and that, as promptly as
practicable after the purchase of Shares pursuant to the Offer and the
satisfaction or waiver of the other conditions set forth in the Merger
Agreement, Purchaser will be merged into the Company, with the Company
continuing as the surviving corporation (the "Merger"), which will be
wholly-owned by EGS. At the effective time of the Merger, each Share outstanding
immediately prior to such time (other than Shares held by the Company as
treasury stock or owned beneficially by Fuji, EGS or Purchaser or any of Fuji's
other subsidiaries, all of which will be cancelled, and other than Shares that
are held by shareholders, if any, who properly exercise their dissenters rights
under applicable law) will be converted into the right to receive the per Share
price that is paid in the Offer, in cash, without interest thereon.




         The Board of Directors of the Company has unanimously determined that
the Offer and the Merger are fair to and in the best interests of the
shareholders of the Company and recommends that the Company's shareholders
tender their Shares in the Offer.

         For purposes of the Offer, Purchaser will be deemed to have accepted
for payment, and thereby purchased, Shares validly tendered and not properly
withdrawn as, if and when Purchaser gives oral or written notice to American
Stock Transfer & Trust Company (the "Depositary") of Purchaser's acceptance for
payment of such Shares pursuant to the Offer. Upon the terms and subject to the
conditions of the Offer, payment for Shares accepted for payment pursuant to the
Offer will be made by deposit of the Offer Price therefor with the Depositary,
which will act as agent for tendering shareholders for the purpose of receiving
payments from Purchaser and transmitting such payments to tendering shareholders
whose Shares have been accepted for payment. Under no circumstances will
interest on the purchase price of Shares be paid by Purchaser because of any
delay in making any payment. Payment for Shares tendered and accepted for
payment pursuant to the Offer will be made only after the timely receipt by the
Depositary of (1) the certificates evidencing such Shares (the "Share
Certificates") or confirmation (a "Book-Entry Confirmation") of a book-entry
transfer of such Shares into the Depositary's account at The Depository Trust
Company (the "Book-Entry Transfer Facility") pursuant to the procedures set
forth in "The Offer--Procedures for Accepting the Offer and Tendering Shares,"
(2) 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 (as defined in the Offer to Purchase) in
lieu of the Letter of Transmittal and (3) any other documents required by the
Letter of Transmittal.

         The term "Expiration Date" means 12:00 a.m., New York City time, on
October 9, 2001, unless Purchaser shall have extended the period of time for
which the Offer is open, in which event the term "Expiration Date" shall mean
the latest time and date at which the Offer, as so extended by Purchaser, shall
expire. Shares tendered pursuant to the Offer may be withdrawn at any time prior
to the Expiration Date. Thereafter, such tenders are irrevocable, except that
they may be withdrawn after November 9, 2001 unless theretofore accepted for
payment as provided in the Offer to Purchase. For a withdrawal of Shares
tendered pursuant to the Offer to be effective, a written, telegraphic or
facsimile transmission notice of withdrawal must be timely received by the
Depositary at one of its addresses set forth on the back cover page of the Offer
to Purchase. Any such notice of withdrawal must specify the name and address of
the person who tendered the Shares to be withdrawn, the number of Shares to be
withdrawn, and the name of the registered holder of such Shares, if different
from that of the person who tendered such Shares. If Share Certificates
evidencing Shares to be withdrawn have been delivered or otherwise identified to
the Depositary, then, prior to the physical release of such Share Certificates,
the serial numbers shown on such Share Certificates must be submitted to the
Depositary and the signature(s) on the notice of withdrawal must be guaranteed
by an Eligible Institution, unless such Shares have been tendered for the
account of an Eligible Institution. If Shares have been tendered pursuant to the
procedure for book-entry transfer as set forth in "The Offer--Procedures for
Accepting the Offer and Tendering Shares," any notice of withdrawal must also
specify the name and number of the account at the Book-Entry Transfer Facility
to be credited with the withdrawn Shares. Withdrawals of Shares may not be
rescinded. Any Shares properly withdrawn will thereafter be deemed not to have
been validly tendered for purposes of the Offer. However, withdrawn Shares may
be re-tendered at any time prior to the Expiration Date by following one of the
procedures described in "The Offer--Procedures for Accepting the Offer and
Tendering Shares." Under the Merger Agreement and pursuant to Rule 14d-11 of the
General Rules and Regulations under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), the Purchaser may, subject to certain conditions,
elect to provide a subsequent offering period following the Expiration Date. The
Purchaser does not currently intend to provide a subsequent offering period in
the Offer, although it reserves the right to do so in its sole discretion. Under
the Exchange Act, no withdrawal rights apply to Shares tendered during a
subsequent offering period and no withdrawal rights apply during the subsequent
offering period with respect to Shares tendered in the Offer and accepted for
payment. See "The Offer--Terms of the Offer." All questions as to the form and
validity (including time of receipt) of any notice of withdrawal will be
determined by Purchaser, in its sole discretion, whose determination will be
final and binding. None of Fuji, EGS, Purchaser, the Company, the Dealer
Manager, the Depositary, the Information Agent or any other person will be under
duty to give notification of any defects or irregularities in any notice of
withdrawal or incur any liability for failure to give any such notification.

         The receipt by a United States stockholder of cash for Shares pursuant
to the Offer or the Merger will be a taxable transaction for U.S. federal income
tax purposes and may also be a taxable transaction under applicable state, local
or foreign tax laws. All shareholders should consult with their own tax advisors



as to the particular tax consequences to them of the Offer and the Merger,
including the effect of United States state and local tax laws or foreign tax
laws.

         The information required to be disclosed by paragraph (d)(1) of Rule
14d-6 of the General Rules and Regulations under the Exchange Act is contained
in the Offer to Purchase and is incorporated herein by reference.

         The Company has provided to Purchaser its list of shareholders and
security position listings for the purpose of disseminating the Offer to holders
of Shares. The Offer to Purchase, the related Letter of Transmittal and other
related materials are being mailed to record holders of Shares and will be
furnished to brokers, dealers, commercial banks, trust companies and similar
persons whose names, or the names of whose nominees, appear on the shareholder
list or, if applicable, who are listed as participants in a clearing agency's
security position listing, for subsequent transmittal to beneficial owners of
Shares.

         The Offer to Purchase and the related Letter of Transmittal contain
important information that should be read carefully before any decision is made
with respect to the Offer.

         Questions and requests for assistance and copies of the Offer to
Purchase, the Letter of Transmittal and all other tender offer materials may be
directed to the Information Agent or the Dealer Manager at their respective
addresses and telephone numbers set forth below and will be furnished promptly
at Purchaser's expense. Purchaser will not pay any fees or commissions to any
broker or dealer or any other person (other than the Dealer Manager and the
Information Agent) for soliciting tenders of Shares pursuant to the Offer.
