                                PLEDGE AGREEMENT

        THIS PLEDGE AGREEMENT, entered into as of November 8, 1999, between
PROGRAPH SYSTEMS, INC., a Pennsylvania corporation (the "Company"), and MARC
OLIN (the "Purchaser").

                                   WITNESSETH:

        WHEREAS, the Purchaser has purchased from the Company 381,854 shares of
the Company's Common Stock (the "Shares"); and

        WHEREAS, the Company has loaned to the Purchaser the sum of $87,826.42
which the Purchaser has used to pay the purchase price of the Shares; and

        WHEREAS, the Purchaser has executed and delivered to the Company a
secured promissory note evidencing such loan (the "Note") and has agreed to
pledge the Shares (the "Pledged Shares") to the Company as security for the
payment of the Note:

        NOW, THEREFORE, it is agreed as follows:

        1. The Purchaser hereby delivers to the Company one or more certificates
representing the Shares, together with two Assignments Separate From Certificate
signed by the Purchaser. The Purchaser hereby pledges and grants a security
interest in the Pledged Shares, including any shares into which the Pledged
Shares may be converted and all proceeds of the Pledged Shares, as security for
the timely payment of all of the Purchaser's obligations under the Note and for
the Purchaser's performance of all of its obligations under this Agreement. In
the event of a default in payment of the Note, the Purchaser hereby appoints the
Company as his true and lawful attorney to take such action as may be necessary
or appropriate to cause the Pledged Shares to be transferred into the name of
the Company or any assignee of the Company and to take any other action on
behalf of the Purchaser permitted hereunder or under applicable law.

        2. The Company agrees to hold the Pledged Shares as security for the
timely payment of all of the Purchaser's obligations under the Note and for the
Purchaser's performance of all of its obligations under this Agreement, as
provided herein. At no time shall the Company dispose of or encumber the Pledged
Shares, except as otherwise provided in this Agreement or the Stock Purchase
Agreement dated as of the date hereof between the Company and the Purchaser (the
"Stock Purchase Agreement").

        3. At all times while the Company is holding the Pledged Shares as
security under this Agreement, the Company shall:

                (a) Collect any dividends that may be declared on the Pledged
        Shares and credit such dividends against any accrued interest or unpaid
        principal under the Note, as part payment;

                                      -4-

<PAGE>
                (b) Collect and hold any shares that may be issued upon
        conversion of the Pledged Shares; and

                (c) Collect and hold any other securities or other property that
        may be distributed with respect to the Pledged Shares.

Such shares and other securities or property shall be subject to the security
interest granted in Section 1 of this Agreement and shall be held by the Company
under this Agreement.

        4. While the Company holds the Pledged Shares as security under this
Agreement, the Purchaser shall have the right to vote the Pledged Shares at all
meetings of the Company's stockholders; provided that the Purchaser is not in
default in the performance of any term of this Agreement, the Stock Purchase
Agreement or Employment Agreement or in any payment due under the Note. In the
event of such a default, the Company shall have the right to the extent
permitted by law to vote and to give consents, ratifications and waivers and
take any other action with respect to the Pledged Shares with the same force and
effect as if the Company were the absolute and sole owner of the Pledged Shares.

        5. Upon payment in full of the outstanding principal balance of the Note
and all interest and other charges due under the Note, subject to the terms of
the Stock Purchase Agreement, the Company shall release from pledge and
redeliver to the Purchaser the certificate(s) representing the Pledged Shares
and the Assignment Separate From Certificate forms.

        6. In the event that the Purchaser fails to perform any term of this
Agreement or fails to make any payment when due under the Note and such failure
continues for 10 days after notice thereof (an "Event of Default"), the Company
shall have all of the rights and remedies of a creditor and secured party at law
and in equity, including (without limitation) the rights and remedies provided
under the Uniform Commercial Code.

               Without limiting the foregoing, after an Event of Default, the
Company may, after giving ten (10) days' prior written notice to the Purchaser
by certified mail at his residence or business address, sell any or all of the
Pledged Shares in such manner and for such price as the Company may determine,
including (without limitation) through a public or private sale or at any
broker's board or on any securities exchange, for cash, upon credit or for
future delivery. The Company is authorized at any such sale, if it deems it
advisable to do so, to restrict the prospective bidders or purchasers of any of
the Pledged Shares to persons who will represent and agree that they are
purchasing for their own account for investment, and not with a view to the
distribution or sale of any of the Pledged Shares, to restrict the prospective
bidders or purchasers and the use any purchaser may make of the Pledged Shares
and impose any other restriction or condition that the Company deems necessary
or advisable under the federal and state securities laws.

                                      -5-

<PAGE>
               Upon any such sale the Company shall have the right to deliver,
assign and transfer to the purchaser thereof the Pledged Shares so sold. Each
purchaser at any such sale shall hold the Pledged Shares so sold absolute, free
from any claim or right of any kind. In case of any sale of any or all of the
Pledged Shares on credit or for future delivery, the Pledged Shares so sold may
be retained by the Company until the selling price is paid by the purchaser
thereof, but the Company shall not incur any liability in case of the failure of
such purchaser to take up and pay for the Shares so sold and, in case of any
such failure, such Shares may again be sold under the terms of this section.

               The Purchaser hereby agrees that any disposition of any or all of
the Pledged Shares by way of a private placement or other method which in the
opinion of the Company is required or advisable under Federal and state
securities laws is commercially reasonable. At any public sale, the Company may
(if it is the highest bidder) purchase all or any part of the Pledged Shares at
such price as the Company deems proper. Out of the proceeds of any sale, the
Company may retain an amount sufficient to pay all amounts then due under the
Note, together with the expenses of the sale and reasonable attorneys' fees. The
Company shall pay the balance of such proceeds, if any, to the Purchaser. The
Purchaser shall be liable for any deficiency that remains after the Company has
exercised its rights under this Agreement.

        7. This Agreement shall be governed by and construed in accordance with
the laws of the Commonwealth of Pennsylvania, without regard to Pennsylvania
choice of law provisions.

        8. This Agreement shall inure to the benefit of, and be binding upon,
the Company and its successors and assigns and be binding upon the purchaser and
the Purchaser's legal representative, heirs, legatees, distributees, assigns and
transferees by operation of law.

        9. This Agreement contains the entire pledge agreement between the
Company and the Purchaser.

        10. The Purchaser will execute any additional agreements, assignments or
documents or take any other actions reasonably required by the Company to
preserve and perfect the security interest in the Pledged Shares granted to the
Company herein and otherwise to effectuate this Agreement.

                                      -6-

                            STOCK PURCHASE AGREEMENT

               THIS STOCK PURCHASE AGREEMENT (this "AGREEMENT") is entered into
as of this 22nd day of December 1999 (the "EFFECTIVE DATE") by and among
PROGRAPH SYSTEMS, INC., a Pennsylvania corporation (the "COMPANY"), and JOSEPH
J. WHANG (the "PURCHASER").

               WHEREAS, the Purchaser desires to purchase 1,018,278 shares of
the Company's common stock (the "COMMON STOCK") (such number of shares owned by
the Purchaser and any shares of capital stock of the Company acquired by the
Purchaser as a result of any subdivision, combination or reclassification of
outstanding shares of Common Stock into a greater or smaller number of shares,
recapitalization, reorganization, reclassification of shares, stock dividend or
like event (collectively, "RECAPITALIZATION EVENTS"), being hereinafter referred
to as the "SHARES");

               NOW, THEREFORE, in consideration of the mutual covenants and
representations herein set forth, the parties hereto hereby agree as follows:

               1. PURCHASE OF SHARES. As of the Effective Date and subject to
the terms and conditions of this Agreement, Purchaser hereby purchases from the
Company, and Company hereby sells to Purchaser, an aggregate of 1,018,278 shares
of the Company's common stock at an aggregate purchase price of $1,048,826.34
(the "PURCHASE PRICE") or $1.03 per Share (the "PURCHASE PRICE PER SHARE").

               2. PAYMENT OF PURCHASE PRICE; CLOSING.

                      (a) DELIVERIES BY PURCHASER. Purchaser hereby delivers to
the Company the full Purchase Price by signing and delivery the form of
promissory note attached as Exhibit A (the "PROMISSORY NOTE"). Purchaser also
hereby delivers to the Company two (2) copies of the Pledge Agreement in the
form of Exhibit B (the "PLEDGE AGREEMENT") a blank Stock Power and Assignment
Separate from Stock Certificate in the form of Exhibit C attached hereto (the
"STOCK POWERS"), both executed by Purchaser.

                      (b) DELIVERIES BY THE COMPANY. Upon its receipt of the
entire Purchase Price and all the documents to be executed and delivered by
Purchaser to the Company under Section 2(a), the Company will issue a duly
executed stock certificate evidencing the Shares registered in Purchaser's name
in accordance with Section 14 with such certificate to be placed in escrow as
provided in the Pledge Agreement.

               3. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser
represents and warrants to the Company that:

                      (a) Purchase for Own Account for Investment. Purchaser is
purchasing the Shares for Purchaser's own account for investment purposes only
and not with a view to, or for sale in connection with, a distribution of the
Shares within the meaning of the Securities Act of 1933, as amended (the "1933
ACT"). Purchaser has no present intention of selling or otherwise disposing of
all or any portion of the Shares and no one other than Purchaser has any
beneficial ownership of any of the Shares.

<PAGE>
                      (b) Access to Information. Purchaser has had access to all
information regarding the Company and its present and prospective business,
assets, liabilities and financial condition that Purchaser reasonably considers
important in making the decision to purchase the Shares, and Purchaser has had
ample opportunity to ask questions of the Company's representatives concerning
such matters and this investment.

                      (c) Understanding of Risks. Purchaser is fully aware of:
(i) the highly speculative nature of the investment in the Shares; (ii) the
financial hazards involved; (iii) the lack of liquidity of the Shares and the
restrictions on transferability of the Shares (e.g., that Purchaser may not be
able to sell or dispose of the Shares or use them as collateral for loans); (iv)
the qualification and backgrounds of the management of the Company; and (v) the
tax consequences of investment in the Shares.

                      (d) Purchaser's Qualifications. Purchaser has a
preexisting personal or business relationship with the Company and/or certain of
its officers and/or directors of a nature and duration sufficient to make
Purchaser aware of the character, business acumen and general business and
financial circumstances of the Company and/or such officers and directors. By
reason of Purchaser's business or financial experience, Purchaser is capable of
evaluating the merits and risks of this investment, has the ability to protect
Purchaser's own interests in this transaction and is financially capable of
bearing a total loss of this investment. Purchaser is an "accredited investor"
as defined under Rule 501 promulgated under the Securities Act of 1933, as
amended.

                      (e) No General Solicitation. At no time was Purchaser
presented with or solicited by any publicly issued or circulated newspaper,
mail, radio, television or other form of general advertising or solicitation in
connection with the offer, sale and purchase of the Shares.

                      (f) Compliance with Securities Laws. Purchaser understands
and acknowledges that, in reliance upon the representations and warranties made
by Purchaser herein, the Shares are not being registered with the Securities and
Exchange Commission ("SEC") under the 1933 Act, but instead are being issued
under an exemption or exemptions from the registration and qualification
requirements of the 1933 Act or applicable state securities laws which impose
certain restrictions on Purchaser's ability to transfer the Shares.

                      (g) Restrictions on Transfer. Purchaser understands that
Purchaser may not transfer any Shares unless such Shares are registered under
the 1933 Act or qualified under the Law or unless, in the opinion of counsel to
the Company, exemptions from such registration and qualification requirements
are available. Purchaser understands that only the Company may file a
registration statement with the SEC and that the Company is under no obligation
to do so with respect to the Shares. Purchaser has also been advised that
exemptions from registration and qualification may not be available or may not
permit Purchaser to transfer all or any of the Shares in the amounts or at the
time proposed by Purchaser.

                      (h) Rule 144. In addition, Purchaser has been advised that
SEC Rule 144 promulgated under the 1933 Act, which permits certain limited sales
of unregistered securities, is not presently available with respect to the
Shares and, in any event, currently requires that the Shares be held for a
minimum of one year, and in certain cases two years, after

                                       2

<PAGE>
they have been purchased and paid for (within the meaning of Rule 144), before
they may be resold under Rule 144. Purchaser understands that Rule 144 may
indefinitely restrict transfer of the Shares so long as Purchaser remains an
"affiliate" of the Company and "current public information" about the Company
(as defined in Rule 144) is not publicly available.

               4. RIGHTS AS STOCKHOLDER. Subject to the terms and conditions of
this Agreement, Purchaser will have all of the rights of a stockholder of the
Company with respect to the Shares from and after the date that Purchaser
delivers payment of the Purchase Price until such time as Purchaser disposes of
the Shares or the Company and/or its assignee(s) exercise(s) the repurchase
options hereunder. Upon an exercise of any right to repurchase hereunder,
Purchaser will have no further rights as a holder of the Shares so purchased
upon such exercise, except the right to receive payment for the Shares so
purchased in accordance with the provisions of this Agreement, and Purchaser
will promptly surrender the stock certificate(s) evidencing the Shares so
purchased to the Company for transfer or cancellation.

               5. RESTRICTIVE LEGEND AND STOP-TRANSFER ORDERS.

                (a)     LEGEND. Purchaser understands and agrees that the
                        Company will place the legend set forth below or a
                        similar legend on any stock certificate(s) evidencing
                        the Shares, together with any other legends that may be
                        required by state or federal securities laws, the
                        Company's Articles of Incorporation or Bylaws, any other
                        agreement between Purchaser and the Company or any
                        agreement between Purchaser and any third party:

                THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
                THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE
                SECURITIES LAWS OF ANY STATE. THESE SECURITIES ARE SUBJECT TO
                RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE
                TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND
                APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR
                EXEMPTION THEREFROM.

                (b)     STOP-TRANSFER INSTRUCTIONS. Purchaser agrees that, in
                        order to insure compliance with the restrictions imposed
                        by this Agreement, the Company may issue appropriate
                        "stop-transfer" instructions to its transfer agent, if
                        any, and if the Company transfers its own securities, it
                        may make appropriate notations to the same effect in its
                        own records.

                (c)     REFUSAL TO TRANSFER. The Company will not be required
                        (i) to transfer on its books any Shares that have been
                        sold or otherwise transferred in violation of any of the
                        provisions of this Agreement or (ii) to treat as owner
                        of such Shares, or to accord the right to vote or pay
                        dividends, to any purchaser or other transferee to whom
                        such Shares have been so transferred.

               6. MARKET STANDOFF AGREEMENT. Purchaser agrees in connection with
any registration of the Company's securities under the 1933 Act that, upon the
request of the

                                       3

<PAGE>
Company or the underwriters managing any registered public offering of the
Company's securities, Purchaser will not sell or otherwise dispose of any Shares
without the prior written consent of the Company or such managing underwriters,
as the case may be, for a period of time (not to exceed 180 days) after the
effective date of such registration requested by such managing underwriters and
subject to all restrictions as the Company or the managing underwriters may
specify for employee-shareholders generally.

               7. COMPLIANCE WITH LAWS AND REGULATIONS. The issuance and the
transfer of the Shares will be subject to and conditioned upon compliance by the
Company and Purchaser with all applicable state and federal laws and regulations
and with all applicable requirements of any stock exchange or automated
quotation system on which the Company's common stock may be listed or quoted at
the time of such issuance or transfer.

               8. SUCCESSORS AND ASSIGNS. The Company may assign any of its
rights under this Agreement, including its rights to repurchase Shares
hereunder. This Agreement will be binding upon and inure to the benefit of the
successors and assigns of the Company. Subject to the restrictions on transfer
herein set forth, this Agreement will be binding upon Purchaser and Purchaser's
heirs, executors, administrators, successors and assigns.

               9. GOVERNING LAW; SEVERABILITY. This Agreement will be governed
by and construed in accordance with the internal laws of the Commonwealth of
Pennsylvania, excluding that body of laws pertaining to conflict of laws. If any
provision of this Agreement is determined by a court of law to be illegal or
unenforceable, then such provision will be enforced to the maximum extent
possible and the other provisions will remain fully effective and enforceable.
