                          COPYRIGHT SECURITY AGREEMENT

                  This Agreement, dated as of April 8, 2003, is made by Fastnet
Corporation, a Pennsylvania corporation (the "Grantor"), having a mailing
address at Two Courtney Place, Suite 130, 3864 Courtney Street, Bethlehem,
Pennsylvania 18017, for the benefit of Equinox Business Credit Corp., a New
Jersey corporation (the "Secured Party"), having a place of business at 120 Wood
Avenue South, Suite 515, Iselin, New Jersey 08830.

                  The Grantor is the owner of all of the copyrighted works,
registrations, and applications for registration described in Schedule A hereto.

                  The Grantor, various subsidiaries of the Grantor (together
with the Grantor, collectively, the "Borrowers") and the Secured Party are
parties to a Loan and Security Agreement of even date herewith (as the same may
be amended, supplemented or restated from time to time, the "Loan Agreement").

                  As a condition to extending credit under the Loan Agreement,
the Lender has required that the Grantor execute this agreement to evidence the
security interest granted to the Secured Party in any copyrights or copyright
applications not expressly covered by other security agreements.

                  ACCORDINGLY, in consideration of the agreements of the Secured
Party set forth in the Loan Agreement, the Grantor hereby agrees as follows:

                  1. DEFINITIONS. Terms defined in the Loan Agreement and not
otherwise defined herein shall have the meanings given them in the Loan
Agreement. In addition, the following terms have the meanings set forth below:

                  "Copyrights" means all of the Grantor's right, title and
         interest in and to all copyrightable works and all copyrights of the
         Grantor and licenses thereunder, whether presently existing or
         hereafter arising, including but not limited to the registered
         copyrights, applications to register copyrights, and unregistered works
         (if any) listed on Schedule A.

                  "Event of Default" means (i) an Event of Default, as defined
         in the Loan Agreement, any other Ancillary Agreement or security
         agreement now in existence or hereafter entered into by the Grantor, or
         (ii) any breach by the Grantor of any of its obligations under this
         Agreement.

                  2. SECURITY INTEREST. In order to secure the Obligations, the
Grantor hereby confirms and acknowledges that it has granted and created (and,
to the extent not previously granted under the Loan Agreement, does hereby grant
and create) a security interest, with power of sale to the extent permitted by
the Loan Agreement and by law, in the Copyrights. This security interest is in
any and all rights of Grantor that may exist or hereafter arise under any
copyright law now or hereinafter in effect in the United States of America or in
any other country.

                                       1

<PAGE>

                  3. REPRESENTATIONS AND WARRANTIES. The Grantor represents and
warrants that (a) the Grantor owns each of the works and rights listed in
Schedule A, free and clear of any Lien other than Permitted Liens, and (b) the
Copyrights listed in Schedule A include all copyrightable works owned or
controlled by the Grantor as of the effective date hereof, excluding immaterial
copyrights.

                  4. SATISFACTION. Upon full payment or satisfaction of the
Obligations and termination of any credit facilities extended to the Borrowers
by the Secured Party, this Agreement, and the rights granted hereunder to the
Secured Party, shall be terminated upon demand by a written termination
statement to the effect that the Secured Party no longer claims a security
interest under this Agreement.

                  5. ADMINISTRATION OF COPYRIGHTS. Prior to the occurrence of an
Event of Default, the Grantor may control and manage the Copyrights, including
the right to make and distribute copies of the works covered thereby, and may
receive and use the income, revenue, profits, and royalties that arise from the
use of the Copyrights and any licenses thereunder, in the same manner and to the
same extent as if this Agreement had not been entered into. The Grantor shall
give the Secured Party prompt notice of any change in the status of said
copyrights or the Grantor's rights thereunder.

                  6. PROTECTION OF COPYRIGHTS. The Grantor covenants that it
will at its own expense protect, defend and maintain the Copyrights to the
extent reasonably advisable in its business, and if the Grantor fails to do so,
the Secured Party may (but shall have no obligation to) do so in the Grantor's
name or in the Secured Party's name, but at the Grantor's expense, and the
Grantor shall reimburse the Secured Party in full for all expenses, including
reasonable attorney's fees incurred by the Secured Party in protecting,
defending and maintaining the Copyrights. The Grantor further covenants that it
will give notice to the Secured Party sufficient to allow the Secured Party to
timely carry out the provisions of this paragraph.

                  7. REMEDIES. Upon the occurrence of an Event of Default, the
Secured Party may, at its option, exercise any one or more of the following
remedies: (a) exercise all rights and remedies available under the UCC, or under
any applicable law; (b) sell, assign, transfer, pledge, encumber or otherwise
dispose of any Copyright; (c) enforce any Copyright, and any licenses
thereunder; and (d) exercise or enforce any or all other rights or remedies
available to the Secured Party by law or agreement against the Copyrights,
against the Grantor or against any other person or property. Upon the exercise
of any remedy by the Secured Party hereunder, the Grantor shall be deemed to
have waived all of its rights provided in 17 U.S.C. ss. 106A or any other "moral
rights of authors." If the Secured Party shall exercise any remedy under this
Agreement, the Grantor shall, at the request of the Secured Party, do any and
all lawful acts and execute any and all proper documents required by the Secured
Party in aid of thereof. For the purposes of this paragraph, the Grantor
appoints the Secured Party as its attorney with the right, but not the duty, to
endorse such Grantor's name on all applications, documents, papers and
instruments necessary for the Secured Party to (i) act in its own name or
enforce or use the Copyrights, (ii) grant or issue any exclusive or
non-exclusive licenses under the Copyrights to any third party, and/or (iii)

                                       2

<PAGE>

sell, assign, transfer, pledge, encumber or otherwise transfer title in or
dispose of any Copyright. The Grantor hereby ratifies all that such attorney
shall lawfully do or cause to be done by virtue hereof. This power of attorney
shall be irrevocable until satisfaction of this Agreement in accordance with
paragraph 4. The Grantor shall reimburse the Secured Party for all reasonable
attorney's fees and expenses of all types incurred by the Secured Party, or its
counsel, in connection with the exercise of the rights of the Secured Party
under this Agreement, together with interest thereon from the date or dates the
same were incurred at the Default Rate.

                  8. GENERAL RIGHTS AND OBLIGATIONS. Except as expressly set
forth herein, the rights and obligations of the Grantor and the Secured Party
with respect to the Copyrights shall in all respects be governed by the Loan
Agreement, the terms of which are incorporated as fully as if set forth at
length herein.

                  IN WITNESS WHEREOF, the Grantor has executed this Agreement as
of the date first above-written.

application appurtenant thereto, may become abandoned, invalidated,
unenforceable, avoided, or avoidable, will otherwise diminish in value, and

of any ground under which this result may occur. Grantor shall take appropriate
action under the circumstances at its expense to halt the infringement of the
Trademarks and shall properly exercise its duty to control the nature and
quality of the goods offered by any licensees in connection with the Licenses.

                           (c) INDEMNIFICATION. (A) Grantor assumes all
responsibility and liability arising from the use of the Trademarks, and Grantor
hereby indemnifies and holds Lender harmless from and against any claim, suit,
loss, damage or expense (including reasonable attorneys' fees) arising out of
Grantor's operations of its business from the use of the Trademarks. (B) In any
suit, proceeding or action brought by Lender under any License for any sum owing
thereunder, or to enforce any provisions of such License, Grantor will indemnify
and keep Lender harmless from and against all expense, loss or damage suffered
by reason of any defense, set off, counterclaim, recoupment or reduction or
liability whatsoever of the obligee thereunder, arising out of a breach of
Grantor of any obligation thereunder or arising out of any other agreement,
indebtedness or liability at any time owing to or in favor of such obligee or
its successors from Grantor, and all such obligations of Grantor shall be and
remain enforceable against and only against Grantor and shall not be enforceable
against Lender.

                           (d) LIMITATION OF LIENS ON COLLATERAL. Grantor will
not create, permit or suffer to exist, and will defend the Collateral against
and take such other action as is necessary to remove any lien, security
interest, encumbrance, claim or right, in or to the Collateral, and will defend
the right, title and interest of Lender in and to any of Grantor's rights under
any License and to the Proceeds thereof against the claims and demands of all
persons whomever.

                           (e) LIMITATIONS ON MODIFICATIONS OF LICENSES. Grantor
will not amend, modify, terminate or waive any provision of any License in any
manner which might materially adversely affect the value of such License or the
Trademarks as Collateral.

                                       4

                           (f) NOTICES. Grantor will advise Lender promptly, in
reasonable detail, (i) of any lien or claim made or asserted against any of the
Collateral, (ii) of any material change in the composition of the Collateral and
(iii) of the occurrence of any other event which would have a material adverse
effect on the value of any of the Collateral or on the security interests
created hereunder.

                           (g) LIMITATION ON FURTHER USES OF TRADEMARKS. Grantor
will not assign, sell, mortgage, lease, transfer, pledge, hypothecate, grant a
security interest in or lien upon, encumber, grant an exclusive or non-exclusive
license, or otherwise dispose of any of the Collateral, without prior written
consent of Lender.

                           (h) EXERCISE OF RIGHTS; DELIVERY OF NOTICES. Grantor
shall (i) exercise promptly and diligently each and every material right which
it may have under each License (other than any right of termination) and (ii)
deliver to Lender a copy of each material demand, notice or document sent or
received by it relating in any way to any License or Trademark.

                  7. LENDER'S APPOINTMENT AS ATTORNEY-IN-FACT.

                           (a) Grantor hereby irrevocably constitutes and
appoints Lender and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of Grantor and in the name of Grantor
or in its own name, from time to time in Lender's discretion, for the purposes
of carrying out the terms of this Agreement, to take any and all appropriate
action and to execute any and all documents and instruments which may be
necessary or desirable to accomplish the purposes of this Agreement and, without
limiting the generality of the foregoing, hereby gives Lender the power and
right, on behalf of Grantor, to do the following:

                                    (i) Upon the occurrence and continuance of
an Event of Default, to ask, demand, collect, receive and give acquittances and
receipts for any and all moneys due and to become due under any License and, in
the name of Grantor or its own name or otherwise, to take possession of and
endorse and collect any checks, drafts, notes, acceptances or other instruments
for the payment of moneys due under any License and to file any claim or to take
any other action or proceeding in any court of law or equity or otherwise deemed
appropriate by Lender for the purpose of collecting any and all such moneys due
under any License whenever payable;

                                    (ii) To pay or discharge taxes, liens,
security interests or other encumbrances levied or placed on or threatened
against the Collateral, to effect any repairs or any insurance called for by the
terms of this Agreement and to pay all or any part of the premiums therefor and
the costs thereof; and

                                    (iii) Upon the occurrence and continuance of
an Event of Default, (A) to direct any party liable for any payment under any of

thereof and to enforce any other right in respect of any Collateral; (D) to
defend any suit, action or proceeding brought against Grantor with respect to
any Collateral; (E) to settle, compromise, or adjust any suit, action or

proceeding described above and, in connection therewith, to give such discharges
or releases as Lender may deem appropriate; and (F) generally to sell, transfer,
pledge, make any agreement with respect to or otherwise deal with any of the
Collateral as fully and completely as though Lender were the absolute owner
thereof for all purposes, and to do, at Lender's option all acts and things
which Lender deems necessary to protect, preserve or realize upon the Collateral
and Lender's security interest therein, in order to effect the intent of this
Agreement, all as fully and effectively as Grantor might do.

                           (b) This power of attorney is a power coupled with an
interest and shall be irrevocable. Notwithstanding the foregoing, Grantor
further agrees to execute any additional documents which Lender may require in
order to confirm this power of attorney, or which Lender may deem necessary to
enforce any of its rights contained in this Agreement.

                           (c) The powers conferred on Lender hereunder are
solely to protect its interests in the Collateral and shall not impose any duty
upon it to exercise any such powers. Lender shall be accountable only for
amounts that it actually receives as a result of the exercise of such powers and
neither it nor any of its officers, directors, employees or agents shall be
responsible to Grantor for any act or failure to act, except for its own gross
(not mere) negligence or willful misconduct.

                           (d) Grantor also authorizes Lender to execute, in
connection with the sale provided for in paragraph 10(b) of this Agreement, any
endorsements, assignments or other instruments of conveyance or transfer with
respect to the Collateral.

                  8. EXECUTION OF POWER OF ATTORNEY. Concurrently with the
execution and delivery hereof, Grantor shall execute and deliver to Lender, in
the form of EXHIBIT I hereto, ten (10) originals of a Power of Attorney for the
implementation of the assignment, sale or other disposal of the Trademarks
pursuant to paragraph 7 hereof.

                  9. PERFORMANCE BY LENDER OF GRANTOR'S OBLIGATIONS. If Grantor
fails to perform or comply with any of its agreements contained herein and
Lender, as provided for by the terms of this Agreement, shall itself perform or
comply, or otherwise cause performance or compliance, with such agreement, the
expenses of Lender incurred in connection with such performance or compliance
shall be payable by Grantor to Lender on demand and shall constitute Obligations
secured hereby.

                  10. REMEDIES, RIGHTS UPON EVENT OF DEFAULT.

                           (a) If an Event of Default shall occur and be
continuing:

                                    (i) All payments received by Grantor under
or in connection with any of the Collateral shall be held by Grantor in trust
for Lender, shall be segregated from other funds of Grantor and shall forthwith
upon receipt by Grantor, be turned over to Lender, in the same form as received
by Grantor (duly indorsed by Grantor to Lender, if required); and

                                    (ii) Any and all such payments so received
by Lender (whether from Grantor or otherwise) may, in the sole discretion of
Lender, be held by Lender as collateral security for, and/or then or at any time
thereafter applied in whole or in part by Lender against all or any part of the
Obligations in such order as Lender shall elect. Any balance of such payments
held by Lender and remaining after payment in full of all the Obligations shall
be paid over to Grantor or to whomsoever may be lawfully entitled to receive the
same.

                           (b) If any Event of Default shall occur and be
continuing, Lender may exercise in addition to all other rights and remedies
granted to it in this Agreement and in any other instrument or agreement
securing, evidencing or relating to the Obligations, all rights and remedies of
a secured party under the Code. Grantor shall remain liable for any deficiency
if the proceeds of any sale or disposition of the Collateral are insufficient to
pay all amounts to which Lender is entitled. Grantor shall also be liable for
the reasonable fees of any attorneys employed by Lender to collect any such
deficiency and also as to any reasonable attorney's fees incurred by Lender with
respect to the collection of any of the Obligations and the enforcement of any
of Lender's respective rights hereunder.

                  11. TERMINATION. At such time as the Obligations are
irrevocably satisfied in full and the Loan Agreement is irrevocably terminated,
this Agreement and the powers of attorney granted hereunder shall terminate and
Lender shall execute and deliver to Grantor all such releases, deeds,
assignments and other instruments as may be necessary or proper to re-vest in
Grantor full title to the Trademarks, subject to any disposition thereof which
may have been made by Lender pursuant hereto.

                  12. NOTICES. Any notice to Lender or Grantor under this
Agreement shall be given in the manner and to the parties designated in the Loan
Agreement.

                  13. NO WAIVER. No course of dealing between Grantor and
Lender, nor any failure to exercise, nor any delay in exercising, on the part of
Lender, any right, power or privilege hereunder or under the Loan Agreement
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right, power or privilege hereunder or thereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.

                  14. CUMULATIVE REMEDIES. All of Lender's rights and remedies
with respect to the Collateral, whether established hereby or by the Loan
Agreement, or by any other agreements or by law, shall be cumulative and may be
exercised singularly or concurrently.

                  15. SEVERABILITY. The provisions of this Agreement are
severable, and if any clause or provision shall be held invalid and
unenforceable in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect only such clause or provision, or part thereof, in
such jurisdiction, and shall not in any manner affect such clause or provision
in any other jurisdiction, or any other clause or provision of this Agreement in
any jurisdiction.

                  16. NO MODIFICATION EXCEPT IN WRITING. Except as provided in
paragraphs 5 and 7, no amendment or waiver of any provision of this Agreement
shall be effective unless the same shall be in writing executed by the parties
hereto.

upon and inure to the benefit of Grantor and Lender, all future holders of the
Obligations and their respective successors and assigns, except that Grantor may
not assign or transfer any of its rights or obligations under this Agreement
without the prior written consent of Lender.

                  18. GOVERNING LAW. This Agreement and the rights and
obligations of the parties hereunder shall be governed by and construed in
accordance with the laws of the State of New Jersey.
