                            STOCK PURCHASE AGREEMENT

               THIS STOCK PURCHASE AGREEMENT (this "AGREEMENT") is entered into
as of this 8th day of November 1999 (the "EFFECTIVE DATE") by and among PROGRAPH
SYSTEMS, INC., a Pennsylvania corporation (the "COMPANY"), and MARC OLIN (the
"PURCHASER").

               WHEREAS, the Purchaser desires to purchase 381,854 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 381,854 shares
of the Company's common stock at an aggregate purchase price of $87,826.42 (the
"PURCHASE PRICE") or $0.23 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.

$87,826.42                                              Pittsburgh, Pennsylvania

        This note is originally secured by a pledge of shares of Common Stock of
the Company pursuant to a Pledge Agreement of even date herewith, which is on
file with the Secretary of the Company.

        If one or more of the provisions hereof shall be declared or held to be
invalid, illegal, or unenforceable in any respect in any jurisdiction, the
validity, legality and enforceability of the remaining provisions hereof shall
not in any way be affected or impaired thereby and any such declaration or
holding shall not invalidate or render unenforceable such provision in any other
jurisdiction.

        In case the note shall become mutilated or defaced, or be destroyed,
lost or stolen, the Borrower shall execute and deliver a new note of like
principal amount in exchange and substitution for the mutilated or defaced note,
or in lieu of and in substitution for the destroyed, lost or stolen note. In the
case of a mutilated or defaced note, the Company shall surrender such note to
the Borrower. In the case of any destroyed, lost or stolen note, the Company
shall furnish to the Borrower evidence to its satisfaction of the destruction,
loss or theft of such note.

        Notwithstanding anything to the contrary herein, in the event the value
of the Shares secured by the Pledge Agreement is insufficient to pay the full
amount due and owing hereunder, the Company may seek reimbursement from Borrower
for any deficiency, but only up to the sum of (i) 30% of the original principal
balance of this note, plus (ii) all interest accrued from the date of this note
to the due date as determined pursuant to the first paragraph of this note.

        To secure the payment of said amount, I, the undersigned, hereby
authorize, irrevocably, any attorney of any court of record, to appear for me in
such court, in term, time or vacation, at any time hereafter, and confess a
judgment without process in favor of the holder of this Note for such amount as
may appear to be unpaid thereon, whether due or not, together with costs, and to
waive

                                      -2-

and release all heirs which may interfere in any such proceedings and to consent
to immediate execution upon such judgment; hereby ratifying and confirming all
that my said attorney may do by virtue hereof.

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

        IN WITNESS WHEREOF, the undersigned has signed, dated and delivered this
note as of the date and year first above written.
