third parties for creating Designs to be manufactured solely by Licensee's
Manufacturing Site(s) according to Section 2.7 of this Agreement.

      2.7 At Licensee's direction, or upon Licensee's consent, Artisan
Components will distribute the Licensed Products to Licensee's Customers, free
of charge to Customers, within [***] after execution by Artisan Components and
the Customer of an applicable End User License Agreement, for Customer's use in
designing, testing, and otherwise creating and verifying Designs for manufacture
solely at Licensee's Manufacturing Sites. For purposes of clarification, the
parties agree that the only Licensed Products that Artisan Components shall be
required to distribute to Customers under this Section shall be Licensed
Products that Artisan Components has previously delivered to Licensee as
completed deliverables. Artisan will distribute the Licensed Products pursuant
to a separate agreement between Artisan Components and the Customer governing
the Customer's use of the Licensed Products (the "End User License Agreement"),
substantially in a mutually-agreed form, [***] in [***] such End User License
Agreement shall [***] corresponding to the [***] in [***],[***],[***],[***]

individual basis. Manufacture will be permitted only at Licensee's Manufacturing
Site(s); provided, however, that Licensee will pay to Artisan Components the
agreed upon Royalties (as set forth in Section 7.2 of this Master License
Agreement).

3. SUPPORT CONDITION, SILICON DEBUGGING AND PRODUCT ENGINEERING

      3.1 In consideration for the technical support and maintenance fees, if
any, described in Appendix B-1 to the Product Schedule, Artisan Components will
provide Licensee with the technical support and maintenance described in
Appendix C-1 to the Product Schedule, if applicable, for the Licensed
Product(s). Such technical support and maintenance is available on an annual
basis only and will be made available throughout the Term, on the terms and
conditions set forth in Appendix C-1, and Artisan Components will provide
Licensee such technical support and maintenance at the highest priority level
that Artisan Components provides to its customers.

      3.2 The design and verification techniques for the Licensed Product(s)
used by Artisan Components depend on the accuracy of models, flows and design
tools; some of which are provided by Artisan Components' licensees and their
target foundries. Due to practical limits on the accuracy of these models, flows
and design tools, the fabricated silicon behavior may not always agree with that
predicted. If and as requested by Licensee, Artisan Components will assist
Licensee in silicon debugging and product engineering at Artisan Components'
[***] rate plus applicable expenses. Silicon debugging and product engineering
do not fall under the technical support and maintenance set forth in Section 3.1
above. To the extent Artisan Components provides any silicon debugging or
product engineering, or otherwise provides Licensee with any revisions and/or
enhancements to the Licensed Product(s), except as otherwise agreed upon, such
revisions and/or enhancements shall be Licensed Product(s) subject to the terms
and conditions of the License Agreement. The foregoing does not limit or
restrict Artisan Components' obligation to correct Errors free of charge during
the Warranty Period or provide free Updates under the terms of this Master
License Agreement and Appendix C-1 to Product Schedule No. 1.

4. TERM

      This Master License Agreement is effective as of the Master Agreement
Effective Date and shall remain in full force and effect for a period of [***]
years, or as the parties may agree in any Product Schedule with respect to the
specific Licensed Product(s) covered by that Product Schedule, unless earlier
terminated as provided herein. Unless earlier terminated as provided herein,
this Master License Agreement will automatically renew at the end of each term
for consecutive [***] year renewal periods, unless either party notifies the
other at least [***] prior to the end of the then current term that it does not
desire this Master License Agreement to renew for another year. Each License
Agreement shall set forth a License Agreement Term which shall be applicable to
it.

      5.1 All orders for Licensed Product(s) shall be evidenced by a Product
Schedule executed by Licensee and Artisan Components, and in connection
therewith, Licensee may issue to Artisan Components a written purchase order.
Except as otherwise agreed in a writing signed by Artisan Components, nothing
contained in any purchase order submitted by Licensee will in any way modify,
delete or add any terms or conditions to said purchases and licenses, and
Licensee hereby waives such purchase order provisions. Except as otherwise
agreed in writing signed by Licensee, nothing contained in any change orders,
invoices or sales acknowledgements submitted by Artisan Components will in any
way modify, delete or add any terms or conditions to said purchases and
licenses, and Artisan Components hereby waives such provisions.

      5.2 With respect to the Licensed Products described in Appendix A-1 hereto
as Group 4 ([***] Library Products and Services - [***]) and Group 5 ([***]
Library Products and Services), Licensee agrees that it will choose one of these
two groups, and notify Artisan in writing of which group it desires Artisan to
proceed with no later than [***]. Licensee's selection may not be changed after
Licensee's written notification.

      5.3 Artisan Components will promptly evaluate any Licensee requested
changes due to modified Licensee design rules or Licensee requested changes to
the library elements to be included in the Licensed Product(s) for both [***]
and [***]. Licensee will complete an Engineering Change Order Request Form, an
"ECO," and submit it to Artisan Components for review. Artisan Components will
promptly notify the Licensee in writing on its ECO Response Form of any [***]
and/or [***], detailing the reasons for such [***]. Licensee will provide
written acceptance or refusal of the terms and conditions of the ECO Response
Form within [***] of having been so notified. Failure to do so will cause
Artisan Components to proceed with the project as if the Licensee's ECO Request
Form had never been received. If Licensee's written notice is one of acceptance
of the [***] and/or [***], then the ECO will be deemed an amendment to the
License Agreement pursuant to Section 22.4 hereof. Unless Licensee's ECO Request
Form explicitly requests Artisan Components to cease work until the ECO process
has been completed, Artisan Components will continue to proceed with the
development as if the ECO Request Form had never been received, unless and until
Licensee's written notice of acceptance of the [***] and/or [***] is received by
Artisan Components. Sample ECO Request and ECO Response Forms are attached as
Exhibits A and B.

expressed as net amounts and shall be made free and clear of, and without

If any applicable law requires Licensee to withhold amounts from any payments to
Artisan Components under the License Agreement, (i) Licensee shall effect such
withholding, remit such amounts to the appropriate taxing authorities and
promptly furnish Artisan Components with tax receipts evidencing the payments of
such amounts, and (ii) the sum payable by Licensee upon which the deduction or
withholding is based shall be increased to the extent necessary to ensure that,
after such deduction or withholding, Artisan Components receives and retains,
free from liability for such deduction or withholding, a net amount equal to the
amount Artisan Components would have received and retained in the absence of
such required deduction or withholding.

      7.7 Artisan Components shall be entitled to have a mutually-agreed upon
auditor, or, if the parties are unable to agree, an auditor selected by two

prior written notice to Licensee, such information and other records including,
[***], supporting documentation for the royalty calculations and [***], and
[***] as may contain under [***] information, any such information disclosed

to maintain such documents for a duration consistent with Licensee's standard
record retention policy, but in no event for less than a period of [***] from
the date such payment from Licensee was due. The auditor selected must agree to
execute a Licensee Confidential Information Exchange Agreement to ensure that
the auditor will report to Artisan Components only upon whether the Royalties
paid were or were not correct, and if incorrect, what are the correct amounts
for the Royalties. Artisan Components agrees to provide Licensee with a copy of
any report prepared by the auditor and disclosed to Artisan Components within
[***] after Artisan Components' receipt of such report. Prompt adjustment
(within [***]) shall be made by Licensee to compensate Artisan Components' for
any errors and/or omissions disclosed by such examination or audit which result

reimburse Licensee for any errors and/or omissions disclosed by such examination
or audit which result in an overpayment of Royalties hereunder. Artisan
Components' is solely responsible for the cost of any audit. The amount of
compensation to any auditor shall not be contingent or based in any manner on
the findings of such audit. If such an examination reveals an underpayment of
more than [***], then Licensee shall promptly reimburse Artisan Components for
the cost of such examination and for the interest due on such amount pursuant to
Section 7.9.

      7.8 All payment amounts stated in the License Agreement, and all payments

the selling exchange rate for conversion of the foreign currency into U.S.
Dollars, quoted for current transactions reported in The Wall Street Journal for
the last business day of the calendar quarter to which such payment pertains.

20. LIBRARY DEVELOPMENT AND VERIFICATION SEQUENCE

      20.1 After the Effective Date, and as set forth in an applicable Product
Schedule, Licensee shall provide Artisan Components with access to Licensee's
Process Information as defined in such Product Schedule, solely for the purposes
of optimizing the Artisan Components library products described in such Product
Schedule to the applicable Licensee Process Information described in such
Product Schedule, for Licensee and its Customers' Use and for distribution to
Licensee and Customers as set forth in this Agreement.

      20.2 Artisan Components shall carry out design rule checking and layout
versus schematics checking to detect compliance of the optimized library to the
applicable Licensee Process Information, and shall provide the results of these
activities in the form of a written report to Licensee. Licensee, at its
discretion, may grant waivers to the applicable Licensee Process Information in
the interest of ensuring an optimum Licensed Product design. If Artisan
Components requires the use of waivers to the applicable Licensee Process
Information then Artisan Components must request and obtain written confirmation
from Licensee of any waivers granted by Licensee.

      20.3 When Artisan Components has created the optimized library as
described in Section 20.2, in accordance with the delivery schedule, Artisan
Components will then verify the design in hardware through use of the Test Chip.
Artisan Components will deliver the physical design database of the Test Chip
containing the optimized library (in GDSII format and containing design elements
mutually agreed upon by the parties) to Licensee for the purpose of
manufacturing the Test Chip.

      20.4 Licensee will produce a set of photographic masks based on the GDSII
from Artisan Components and will manufacture the Test Chip and deliver it to
Artisan Components in the form of untested dice.

      20.5 Upon receipt of the Test Chip, Artisan Components will carry out
testing and verification using the Artisan Components test suites to verify
functional and electrical compliance with the applicable Licensee Process
Information. Such testing shall include testing at elevated temperature and
exposure to elevated operating conditions, as defined in the product
specifications agreed upon by the parties at the commencement of library
development. Artisan Components shall issue a written report to Licensee
summarizing the results of such tests and representing that the library is fully
compatible with the applicable Licensee Process Information (subject to the
waivers granted in Section 20.2 above). The written report shall be provided to
Licensee within [***] after the Test Chip is provided to Artisan Components or
at a date mutually agreed in advance by the parties as shown in the appropriate
Product Schedule. If the Artisan Components test suites indicate a functionality
problem arising from either the optimized library or the applicable Licensee
Process Information, the parties shall negotiate in good faith to determine the
corrective action prior to release of such report to third parties.

      20.6 At Licensee's request and at a mutually agreeable time and place,
Artisan Components agrees to provide a minimum level of sales training on the
optimized library.

                      EIGHTH AMENDMENT TO CREDIT AGREEMENT

     This Eighth Amendment to Credit  Agreement  ("Amendment") is made this 13th
day of May,  2002,  by and among  Phoenix  Color Corp.  ("Phoenix"),  a Delaware
corporation,  PCC Express, Inc. ("PCC"), a Delaware  corporation,  Phoenix (MD.)
Realty, LLC ("Realty"), a Maryland limited liability company, and TechniGraphix,
Inc.  ("TechniGraphix"),   a  Maryland  corporation  (singly  a  "Borrower"  and
collectively, "Borrowers"), the lending institutions listed from time to time on
Schedule A to the Credit  Agreement (as defined below)  (singly,  a "Lender" and
collectively, "Lenders"), Wachovia Bank, National Association (formerly known as
First Union National Bank), a national banking association, as issuer of letters
of credit (in such capacity,  "Issuer") and Wachovia Bank, National  Association
(formerly  known as First Union  National  Bank),  as  administrative  agent for
Issuer and Lenders (in such capacity, "Agent").

                                   BACKGROUND

     A. Borrowers,  Agent,  Issuer and Lenders are parties to a Credit Agreement
dated  September  15, 1998 (as amended or otherwise  modified from time to time,
the "Credit Agreement"),  pursuant to which certain financing  arrangements were
established for the benefit of Borrowers.  All  capitalized  terms not otherwise
defined herein shall have the respective meanings ascribed thereto in the Credit
Agreement.

     B.  Borrowers  have requested  that Agent,  Issuer and Lenders  modify,  in
certain respects, the Credit Agreement and Agent, Issuer and Lenders have agreed
to make such  modifications,  all as more fully set forth  herein and subject to
the terms and conditions hereof.

     NOW,  THEREFORE,  with the foregoing  Background  incorporated by reference
herein and made part hereof, the parties hereto,  intending to be legally bound,
hereby agree as follows:

     1. Amendments to Credit Agreement.

            a.  The  definitions  of  "Consolidated  Capital  Expenditures"  and
"Equipment  Availability"  set forth in Section 1.1 of the Credit  Agreement are
hereby   deleted  in  their   entirety  and  replaced  with  the  following  new
definitions:

          "Consolidated Capital Expenditures" - For any period, the aggregate of
          all capital expenditures  (including that portion of Capitalized Lease
          Obligations  incurred  during that period) made by Borrowers and their
          Subsidiaries   during  such   period  in  respect  of  the   purchase,
          construction   or  other   acquisition  of  fixed  or  capital  assets
          determined in accordance with GAAP; provided however,  that commencing
          January  1,  2002,  "Consolidated  Capital  Expenditures"  shall  also
          include the purchase price (determined as of the effective date of the
          applicable  operating  lease) of all  equipment of Borrowers and their
          Subsidiaries subject to operating leases during such period;  provided
          further  that,  Consolidated  Capital  Expenditures  shall not include
          capital  expenditures  made by Borrowers in respect of the purchase of
          the Kolbus American  binding line and Timson  printing press.  For the
          purposes hereof, any deposits made by any Borrower or its

<PAGE>

          Subsidiaries for the purposes of acquiring or leasing fixed or capital
          assets shall be deemed Consolidated Capital Expenditures.

          "Equipment Availability"- the sum of Six Million Dollars ($6,000,000).
          The aggregate amount of Equipment Availability shall reduce by (x) One
          Hundred  Thousand   Dollars   ($100,000)  per  month  for  each  month
          commencing  July 1,  2002  for the  first  twelve  (12)  months,  and,
          commencing July 1, 2003, Two Hundred Thousand  Dollars  ($200,000) per
          month  for  each  month  thereafter,  (y) if all or any  portion  of a
          security  deposit  financed by Lenders shall be returned to Borrowers,
          an amount equal to the returned  portion of such security  deposit and
          (z) by an amount  equal to fifty  percent  (50%) of the  amount of the
          Krause Settlement paid to Agent with such amount under this clause (z)
          being applied in the inverse order of reductions.

          b. The following new definition shall be added (in alphabetical order)
to Section 1.1 of the Credit Agreement:

          "Krause  Settlement " An amount equal to the proceeds  received by any
          Borrower  (or any  Subsidiary  of  Borrower) as a result of any award,
          judgment, settlement or any other payment in connection with Phoenix's
          litigation  against Krause Biagosch GmbH, Krause America,  Inc. or any
          other  entity  related  thereto,  as such  litigation  is described in
          Phoenix's 10-k dated March 26, 2002.

          c. Section  2.6(ea) of the Credit  Agreement is hereby  deleted in its
entirety and replaced with the following:

          "(e) Borrowers shall unconditionally pay to Agent an amendment fee, in
          consideration of the  accommodation  granted under the Sixth Amendment
          of One  Hundred  Fifty  Thousand  Dollars  ($150,000),  which is fully
          earned upon execution of the Sixth Amendment,  and which is payable in
          the amount of Seventy Five Thousand Dollars  ($75,000) on December 31,
          2002,  and Seventy  Five  Thousand  Dollars  ($75,000) on December 31,
          2003;  provided  however,  that  the  entire  amendment  fee  (or  the
          remaining  unpaid  portion,  if  applicable)  shall be  payable on the
          termination of the Revolving Credit, if such termination  occurs prior
          to either such payment date;  provided further that the portion of the
          fee that is payable on December 31, 2003 shall be reduced by an amount
          equal to the  product  of (i) the actual  amount of Krause  Settlement
          proceeds paid to Agent times (ii) .03.

          d. Section 2 of the Credit Agreement is hereby amended by adding a new
Section 2.13 which shall read as follows:

restated in its entirety as follows:

          "(d) Borrowers shall not expend for Consolidated  Capital Expenditures
          during any rolling  four  quarter  period  measured on the last day of
          each fiscal quarter, an amount greater than the amount set forth below
          during the  following  periods,  less during any period,  the net cash
          proceeds  received by  Borrowers  from any  equipment  sale during the
          applicable period:

          March 31, 2003 and thereafter                        $5,000,000

          f.  Section  5.8(e) of the  Credit  Agreement  is hereby  amended  and
restated in its entirety and shall read as follows:

          "(e) Fixed Charge Coverage Ratio:  Borrowers shall have and maintain a
          Fixed Charge Coverage Ratio of not less than the following  during the
          following  periods  (measured  quarterly  on a  rolling  four  quarter
          basis):

          Period Ending:                              Maximum Ratio:
          -------------                               -------------
          6/30/02                                     1.0 to 1.0

          and thereafter                              1.2 to 1.0

waive the Existing Default. Upon the effectiveness of this Amendment,  Agent and
Lenders hereby waive the Existing  Default.  The waiver of the Existing  Default
shall not constitute a waiver of any other Default or Event of Default.  Nothing
contained  herein shall  obligate Agent or Lenders to grant any future waiver of
any other  Default or Event of Default  or be deemed to  constitute  a course of
conduct.
