-6-

--------------------------------------------------------------------------------

involving the Borrower or any other Loan Party or any of their respective
property or assets:
(a)    All Senior Debt shall first be indefeasibly paid in full in cash (or
another form which the Senior Agent has indicated in writing is acceptable)
before any Distribution, whether in cash, securities or other property (other
than Reorganization Securities), shall be made to the Junior Lender or any
Junior Lender on account of any Subordinated Debt.
(b)    Any Distribution, whether in cash, securities or other property (other
than Reorganization Securities) which would otherwise, but for the terms hereof,
be payable or deliverable in respect of any Subordinated Debt shall be paid or
delivered directly to the Senior Agent (to be held and/or applied by the Senior
Agent in accordance with the terms of the Senior Debt Documents) until all
Senior Debt is indefeasibly paid in full in cash (or another form which the
Senior Agent has indicated in writing is acceptable). The Junior Lender,
irrevocably authorizes, empowers and directs any debtor, debtor in possession,
receiver, trustee, liquidator, custodian, conservator, or other Person having
authority, to pay or otherwise deliver (or cause the same) all such
Distributions to the Senior Agent (other than any Distribution constituting a
Permitted Subordinated Debt Payment that was received by the Junior Lender at a
time when such payment was permitted by the terms of this Agreement which was
prior to the commencement of the applicable Proceeding) until all Senior Debt is
indefeasibly paid in full in cash (or another form acceptable to the Senior
Agent in writing), and thereafter, to pay or otherwise deliver them to the
Junior Lender. The Junior Lender also irrevocably authorizes and empowers the
Senior Agent, in the name of Junior Lender, to demand, sue for, collect and
receive any and all such Distributions.
(c)    The Junior Lender agrees not to initiate, prosecute, or participate in
(or directly or indirectly cause or support any other Person to do the same) any
claim, action, or other proceeding challenging the enforceability, validity,
perfection, or priority of the Senior Debt, or any Liens and security interests
securing the Senior Debt. The Senior Agent agrees not to initiate, prosecute, or

such Liens and security interests are expressly permitted hereunder.
(d)    Following the indefeasible payment in full in cash (or another form which
the Senior Agent has indicated in writing is acceptable) of the Senior Debt, any
Distribution which may be payable to or deliverable in respect of the
Subordinated Debt shall be paid to the Junior Lender for application in
satisfaction of the Subordinated Debt until such time as all the Subordinated
Debt shall have been paid in full in cash.

the Senior Agent its agent and attorney-in-fact to (i) prepare, execute, verify,
deliver, and file commercially reasonable proofs of claim in respect of the
Subordinated Debt upon the failure of the Junior Lender promptly to do so prior
to 15 Business Days before the expiration of the time to file any such proof of
claim and (ii) vote such claim in any such Proceeding upon the failure of the
Junior Lender to do so prior to 10 Business Days before the expiration of the
time to vote any such claim; provided, the Senior Agent shall have no obligation
or duty to prepare, execute, verify, deliver, file, and/or vote any such proof
of claim (and its action or inaction shall not give rise to any

-7-

--------------------------------------------------------------------------------

claims or liability against the Senior Agent or any Senior Lender under this
Agreement or otherwise). In the event that the Senior Agent votes any claim in
accordance with the authority granted hereby, the Junior Lender shall not be
entitled to change or withdraw such vote.
(f)    The Senior Debt shall continue to be treated as Senior Debt and the
provisions of this Agreement shall continue to govern the relative rights and
priorities of the Senior Agent, the Senior Lenders and the Junior Lender, in or
outside of a Proceeding, even if all or part of the Senior Debt, or any payments
or proceeds thereof or of the Collateral, or the Liens or security interests
securing the Senior Debt are subordinated, set aside, avoided, invalidated or
disallowed in connection with any such Proceeding or otherwise, and this
Agreement shall be reinstated if at any time any payment of any of the Senior
Debt or proceeds of Collateral thereof is rescinded, avoided, subordinated,
invalidated or must otherwise be returned or set aside (including, without
limitation, by settlement of any claim for such avoidance or recission or
similar recovery) by any holder of Senior Debt or any representative of such
holder.
(g)    So long as any Senior Debt has not been indefeasibly paid in full in cash
(or another form which the Senior Agent has indicated in writing is acceptable),
without the express prior written consent of the Senior Agent, Junior Lender
shall not (and shall not support any other Person in order to) (i) with respect
to any rights under any Subordinated Debt Document, seek in respect of any part
of the Collateral or proceeds thereof or any Lien which may exist thereon, any
relief from or modification of the automatic stay as provided in Section 362 of
the Bankruptcy Code or, seek or accept any form of adequate protection under
either or both Sections 362 and 363 of the Bankruptcy Code with respect thereto;
(ii) oppose or object to Senior Agent and/or any Senior Lender obtaining a Lien
or grant of administrative claim in connection with a grant of adequate
protection, use of cash collateral or post-petition financing under Sections
362, 363 or 364 of the Bankruptcy Code; (iii) oppose or object to the use of
cash collateral by any Loan Party that is supported by the Senior Agent; (iv)
oppose or object to any post-petition financing (including without limitation
any debtor-in-possession financing) provided by Senior Agent and/or any of the
Senior Lenders or provided by a third party pursuant to Section 364 of the
Bankruptcy Code (including without limitation on a priming basis) on terms
acceptable to Senior Agent provided that the aggregate amount of such DIP
Financing provided by the Senior Lenders and any cash collateral use shall not
exceed 110% of the then outstanding principal balance of the Senior Debt as of
the date of filing of the Proceeding (“Permitted DIP Financing”), (v) oppose or
object to or withhold consent from the disposition of assets by any Loan Party
under Section 363 of the Bankruptcy Code that is supported by the Senior Agent
so long as (x) the Liens of the Junior Lender attach to the proceeds of such
disposition in the order and priority set forth herein, (y) the proceeds of such
disposition shall be applied to the Senior Debt in accordance with Section 2.7
and (z) the application of such proceeds to the principal portion of the Senior
Debt shall result in a permanent reduction of the Senior Debt, in the amount of
such proceeds so applied; (vi) make an election pursuant to Section 1111(b) of
the Bankruptcy Code; (vii) oppose or object to the determination of the extent
of any Liens held by any of the Senior Agent and/or the Senior Lenders; (viii)
oppose or object to the payment of interest and expenses of the Senior Agent
and/or the Senior Lenders as provided under Sections 363 or 506(b) and (c) of
the Bankruptcy Code; (ix) assert or enforce, at any time when any Senior Debt
exists, any claim under Section 506(c) of the Bankruptcy Code senior to or on a
parity with the Senior Debt for costs or expenses of preserving or disposing of
any Collateral;

-8-

--------------------------------------------------------------------------------

(x) serve as a formal plan proponent of any plan of reorganization or
liquidation or similar dispositive restructuring plan that (A) does not
expressly provide for the indefeasible payment in full in cash of the Senior
Debt concurrently with the confirmation of such plan or (B) impairs in any way
the rights and remedies of the Senior Agent or any Senior Lender under the
Senior Debt Documents or under this Agreement, provided that nothing herein
shall prohibit Junior Lender from voting for a plan that does not meet the
conditions of (A) and (B) herein so long as such plan is otherwise consistent
with the priorities and preferences (and Junior Lender’s obligations) as set
forth in this Agreement; or (x) object to, contest or oppose in any manner the
exercise by the Senior Agent or any Senior Lender of the right (or amount) to
“credit bid” the Senior Debt pursuant to Section 363(k) of the Bankruptcy Code
or other applicable law in any Proceeding (it being understood that nothing in
this Agreement shall be deemed to prohibit the Junior Lender or any Junior
Lender from “credit bidding” the Subordinated Debt pursuant to Section 363(k) of
the Bankruptcy Code or other applicable law in any Proceeding, so long as the
aggregate amount of any bid by the Junior Lender or the Junior Lender includes a
cash payment sufficient for the indefeasible payment in full of the Senior
Debt). Notwithstanding the foregoing, in connection with any Proceeding, the
Junior Lender may seek or request adequate protection replacement Liens in
respect of the Collateral but only if the Senior Lenders are granted adequate
protection Liens, and then such adequate protection Liens granted in favor of
the Junior Lender may be granted only in the same Collateral as the Senior
Lenders’ adequate protection Lien is granted, and such Lien granted to the
Junior Lender shall be subordinated to the Liens securing the Senior Debt (and
any cash collateral usage or DIP Financing (as defined below)) on the same basis
as the Liens securing the Subordinated Debt are subordinated to the Liens
securing the Senior Debt hereunder. If and to the extent any such additional or
replacement Liens are insufficient to provide adequate protection of the
interests of the Junior Lender, any claim of the Junior Lender under Section
507(b) of the Bankruptcy Code shall be subordinate in right of payment to any
claim of the Senior Agent and Senior Lenders consistent with this Agreement. In
addition, the Junior Lender may seek adequate protection with respect to its
rights in the Collateral in the form of cash payments solely with respect to
interest on the Subordinated Debt, but only if the Senior Lenders are granted
adequate protection in the form of cash payments with respect to interest on the
Senior Debt. If the Junior Lender receives post-petition interest and/or
adequate protection payments in any Proceeding and the Senior Lenders do not
receive indefeasible payment in full in cash (or another form which the Senior
Agent has indicated in writing is acceptable) of all Senior Debt upon the
effectiveness of any plan of reorganization or liquidation for, or conclusion
of, the Proceeding, then the Junior Lender shall segregate and pay over to the
Senior Lenders the amount of adequate protection payments and/or post-petition
interest received up to the amount of the shortfall in payment in full of the
Senior Debt. Notwithstanding the foregoing, the Senior Lenders shall not be
deemed to have consented to, and expressly retain their right to object to, the
grant of adequate protection in the form of cash payments to the Junior Lender.
2.3.    Subordinated Debt Payment Restrictions.
(a)    Notwithstanding the terms of the Subordinated Debt Documents, each Loan
Party hereby agrees that it may not make, and the Junior Lender hereby agrees
that it will not demand or accept and it will not permit any Junior Lender to
demand or accept, any Distribution on account of any Subordinated Debt until the
Senior Debt is indefeasibly paid in full

acceptable), in each case other than Permitted Subordinated Debt Payments.
Notwithstanding the forgoing, each Loan Party and the Junior Lender further
agree that, subject to the limitations set forth in Section 2.3(d) below, no
Permitted Subordinated Debt Payment may be made by any Loan Party or accepted by
the Junior Lender or any Junior Lender if, at the time of such payment, the
Junior Lender shall have received a Senior Default Notice from the Senior Agent
stating that one or more Senior Defaults identified in the applicable Senior
Default Notice exist or would be created by the making of such payment, unless
and until (A) Junior Lender has received written notice from Senior Agent that
each such Senior Default has been cured or waived, (B) the payment of the Senior
Debt in full in cash (or another form which the Senior Agent has indicated in
writing is acceptable), or (C) 180 days shall have elapsed since the date such
Senior Default Notice was received by the Junior Lender; provided, however, that
notwithstanding anything to the contrary set forth herein (including the receipt
by the Junior Lender of a Senior Default Notice), the Junior Lender may take and
Borrower may make Permitted Non-Blockable Subordinated Debt Payments at any
time.
(b)    The Loan Parties shall resume making Permitted Subordinated Debt Payments
in respect of the Subordinated Debt (including payments that were blocked
pursuant to Section 2.3(a) above) only upon the earlier to occur of (A) the cure
or waiver of all such Senior Defaults identified in the applicable Senior
Default Notice, and receipt by Junior Lender of written notice from Senior Agent
of such cure or waiver, (B)    the payment of the Senior Debt in full in cash
(or another form which the Senior Agent has indicated in writing is acceptable)
and the irrevocable termination in writing of all commitments to lend or
otherwise extend credit under the Senior Debt Documents, or (C)    the
expiration of such 180 day period described in Section 2.3(a) above).
(c)    No Senior Default shall be deemed to have been cured or waived for
purposes of this Section 2.3 unless and until each of the Borrower and the
Junior Lender shall have received a written confirmation thereof from the Senior
Agent. The Senior Agent shall promptly deliver a written notice to the Junior
Lender after waiver or cure of any Senior Default.
(d)    Notwithstanding any provision of this Section 2.3 to the contrary:
(i)    solely for purposes of Section 2.3(a) the Senior Agent may deliver a
Senior Default Notice not more than two (2) times during the term of the Senior
Credit Agreement, and at least ninety (90) days must pass between any such
Senior Default Notices delivered pursuant to Section 2.3(a) (i.e. Senior Agent
shall not have the right to block any three (3) consecutive quarterly payments
under the Subordinated Note pursuant to its rights under Section 2.3(aV);
(ii)    the failure of any Loan Party to make any Distribution with respect to
the Subordinated Debt by reason of the operation of this Section 2.3 shall not
be construed as preventing the occurrence of a Subordinated Debt Default under
the applicable Subordinated Debt Documents; and
(iii)    the provisions of this Section 2.3 shall not apply at any time at which
Section 2.2 would be applicable.

-10-

(a)    Until the Senior Debt is indefeasibly paid in full in cash (or another
form which the Senior Agent has indicated in writing is acceptable), the Junior
Lender, on behalf of itself and the Subordinated Creditors, shall not, without
the prior written consent of the Senior Agent, take any Enforcement Action with
respect to the Subordinated Debt until the passage of 180 days from the date of
receipt by the Senior Agent of a Subordinated Debt Default Notice (the
“Standstill Period”), provided that solely with respect to any Enforcement
Action that relates to the Collateral, the Junior Lender shall not commence such
Enforcement Action until 45 days after the Senior Agent’s receipt of written
notice of Subordinated Creditor’s intention to take any such Enforcement Action
after expiration of the Standstill Period (which written notice may be issued
during the Standstill Period), if any Subordinated Debt Default described
therein shall not have been cured or waived within such period; provided,
further that notwithstanding anything herein to the contrary, in no event shall
Subordinated Creditor take any Enforcement Action with respect to the Collateral
if, notwithstanding the expiration of the Standstill Period, the Senior Agent or
the Senior Lenders shall have commenced and are diligently pursuing Enforcement
Action with respect to all or substantially all of the Collateral (prompt notice
of such exercise to be given to the Subordinated Creditor by Senior Agent).
(b)    Notwithstanding the foregoing, inside or outside of a Proceeding, the
Junior Lender may (i) declare a default or event of default under the
Subordinated Debt Documents and declare or join in the declaration of the
Subordinated Debt to be due and payable or otherwise accelerate the maturity of
the principal of the Subordinated Debt, accrued interest thereon, prepayment
premium or other amounts due thereunder; (ii) file a claim or statement of
interest with respect to the Subordinated Debt; (iii) take any action (not
adverse to the priority, status, extent or enforceability of the Liens on the
Collateral securing the Senior Debt, or the rights of any Senior Agent or the
Senior Lenders to exercise remedies in respect thereof) in order to create,
perfect, preserve or protect its Lien on the Collateral; (iv) file any necessary
responsive or defensive pleadings in opposition to any motion, claim, adversary
proceeding or other pleading made by any person objecting to or otherwise
seeking the disallowance of the claims of the Junior Lender, including any
claims secured by the Collateral, if any, in each case, in accordance with the
terms of this Agreement; (v) subject to the rights of the Senior Agent under
Section 2.2, vote on any plan of reorganization, file any proof of claim, make
other filings and make any arguments and motions that are, in each case, in
accordance with applicable law and the terms of this Agreement (including,
without limitation, Section 2.2); (vi) unless objected to by Senior Agent and
subject to Section 2.2, exercise any of its rights or remedies with respect to
the Collateral during a Proceeding; and (vii) subject to Section 2.2, file any
pleadings, objections, motions or agreements which assert rights or interests
available to unsecured creditors of the Loan Parties arising under any
Proceeding, the Bankruptcy Code or applicable non-bankruptcy law, so long as
such actions are not adverse to and would not conflict with this Agreement;
provided that in the event that any Junior Lender becomes a judgment Lien
creditor in respect of Collateral as a result of its enforcement of its rights
as an unsecured creditor with respect to the Subordinated Debt, such judgment
Lien shall be subject to the terms of this Agreement for all purposes (including
without limitation in relation to the Senior Debt) as the other Liens securing
the Subordinated Debt are subject to this Agreement.

-11-

--------------------------------------------------------------------------------

(c)    If Junior Lender shall receive any Distribution on account of the
Subordinated Debt in connection with any Enforcement Action exercised in
accordance with this Section 2.4 or otherwise, Junior Lender shall segregate and
hold such payment in trust for the benefit of the Senior Agent and the Senior
Lenders and promptly pay it over to Senior Agent for application (in accordance
with the Senior Debt Documents) to the payment of the Senior Debt then remaining
unpaid, until all of the Senior Debt is indefeasibly paid in full in cash (or
another form acceptable to the Senior Agent in writing).
2.5.    Incorrect Payments. Both in and outside of a Proceeding, and until the
Senior Debt has been indefeasibly paid in full in cash (or another form which
the Senior Agent has indicated in writing is acceptable), if any Collateral or
proceeds thereof or Distribution on account of the Subordinated Debt not
permitted to be made by the Borrower or any Loan Party or accepted by the Junior
Lender or any Junior Lender under this Agreement is received by the Junior
Lender or any Junior Lender, such Collateral or proceeds thereof and/or
Distribution shall be segregated and deemed to be held in trust by the Junior
Lender for the benefit of the Senior Agent and the Senior Lenders, and shall be
promptly paid over to the Senior Agent for application (in accordance with the
Senior Debt Documents) to the payment of the Senior Debt then remaining unpaid,
until all of the Senior Debt is indefeasibly paid in full in cash (or another
form which to the Senior Agent has indicated in writing is acceptable) and all
commitments to lend or otherwise extend credit under the Senior Debt Documents
have irrevocably terminated in writing.
2.6.    Subordination of Liens and Security Interests. Notwithstanding the date,
manner or order of grant, attachment or perfection of any Liens and security
interests of Junior Lender in the Collateral, until the Senior Debt has been
indefeasibly paid in full in cash, any Liens and security interests of the
Junior Lender in the Collateral which may exist from time to time (whether the
same exist in breach of this Agreement or otherwise) shall be and hereby are
subordinated for all purposes and in all respects to the Liens and security
interests of the Senior Agent and the Senior Lenders in the Collateral,
regardless of the time, manner, perfection or order of perfection of any such
Liens and security interests. The Junior Lender, on behalf of itself and the
Junior Creditors, agrees that it will not, and will not cause or support any
other Person to, at any time contest, seek to avoid or subordinate the validity,
perfection, priority, extent or enforceability of the Senior Debt, the Senior
Debt Documents, this Agreement or any Liens and security interests of the Senior
Agent and the Senior Lenders in the Collateral securing the Senior Debt. The
Junior Lender agrees that it will not acquire any Lien on or security interest
in any property or asset unless the Senior Agent, for the benefit of the Senior
Lenders, has a senior, valid, perfected and enforceable Lien on and security
interest in such property or asset pursuant to the Senior Loan Documents.
Subject to compliance with the terms of this Agreement, the Senior Agent, on
behalf of itself and the Senior Lenders, agrees that it will not, and will not
cause or support any other Person to, at any time contest, or seek to avoid the
validity, perfection, priority, extent or enforceability of the Subordinated
Debt, the Subordinated Debt Documents, this Agreement or any Liens and security
interests of the Junior Lender in the Collateral securing the Subordinated Debt
permitted hereunder. The Senior Agent agrees that it will not acquire any Lien
on or security interest in any property or asset unless the Junior Lender is
permitted to obtain valid, perfected and enforceable Lien on and security
interest in such property or asset pursuant to the Subordinated Debt Documents,
and is also expressly permitted, pursuant to this Agreement, to obtain a Lien on

-12-

--------------------------------------------------------------------------------

and security interest in such property or asset, subordinate only to the Liens
of the Senior Agent pursuant to the Senior Debt Documents.
2.7.    Application of Proceeds from Sale or other Disposition of the
Collateral. Subject to Section 2.2(g) and Section 2.11, in the event of any
sale, transfer or other disposition (including without limitation a casualty
loss, taking through eminent domain or otherwise) of the Collateral, the
proceeds resulting therefrom (including without limitation insurance proceeds)
shall be applied in accordance with the terms of the Senior Debt Documents or as
otherwise consented to by the Senior Agent and Required Lenders (as defined in
the Senior Credit Agreement) until such time as the Senior Debt is indefeasibly
paid in full in cash; provided (A) the Liens of the Junior Lender attach to the
proceeds of such disposition, and (B) any such proceeds received after any
Enforcement Action by Senior Agent are applied first, in permanent reduction of
the Senior Debt, and, following the indefeasible payment in full of the Senior
Debt, to the Subordinated Debt.
2.8.    Sale, Transfer or other Disposition of Subordinated Debt
(a)    The Junior Lender shall not sell, assign, pledge, dispose of or otherwise
transfer all or any portion of the Subordinated Debt or any Subordinated Debt
Document unless, prior to the consummation of any such action, the transferee
thereof shall execute and deliver to the Senior Agent a joinder agreement
substantially similar to the agreement attached hereto as Exhibit A, providing
for the continued subordination of the Subordinated Debt to the Senior Debt as
provided herein and for the continued effectiveness of all of the rights of the
Senior Agent and the Senior Lenders arising under this Agreement.
(b)    Notwithstanding the failure of any transferee to execute or deliver an
agreement substantially identical to this Agreement, the subordination effected
hereby shall survive any sale, assignment, pledge, disposition or other transfer
of all or any portion of the Subordinated Debt, and the terms of this Agreement
shall be binding upon the successors and assigns of Junior Lender, as provided
in Section 11 hereof.
2.9.    Legends. Until the termination of this Agreement in accordance with
Section 17 hereof, the Junior Lender will cause to be clearly, conspicuously and
prominently inserted on the face of each agreement, document and/or instrument
representing or evidencing any of the Subordinated Debt, the following legend:
“This instrument/agreement and the rights and obligations evidenced hereby are
subordinate in the manner and to the extent set forth in that certain
Subordination and Intercreditor Agreement (the “Subordination Agreement”) dated
as of October 31, 2014, by and among PDI, Inc., a Delaware Corporation (the
“Borrower”), RedPath Equityholder Representative, LLC, a Delaware limited
liability company (together with its permitted successors and assigns in such
capacity, the “Junior Lender”), and SWK Funding LLC, a Delaware limited
liability company, as the agent, sole lead arranger and sole bookrunner under
the Senior Credit Agreement defined below (together with its permitted
successors and assigns in such capacity, including in such capacity under any
Permitted Refinancing Debt (as hereinafter defined), the “Senior Agent), to the
indebtedness (including interest)

-13-

--------------------------------------------------------------------------------

owed pursuant to that certain Credit Agreement dated as of October 31, 2014,
among the Borrower, the lenders party thereto from time to time, and the Senior
Agent, as such Credit Agreement has been and hereafter may be amended,
supplemented, or otherwise modified from time to time and to indebtedness
refinancing the indebtedness under that agreement as contemplated by the
Subordination Agreement; and each holder of this instrument, by its acceptance
hereof, irrevocably agrees to be bound by the provisions of the Subordination
Agreement.”
2.10.    Perfection; Delivery of Collateral; Deposit Accounts.
(a)    In the event that the Senior Agent (or any Senior Lender) takes
possession of or has “control” (as such term is used in the Uniform Commercial
Code as in effect in each applicable jurisdiction) over any Collateral for
purposes of perfecting its Liens therein (including, without limitation, stock
certificates, depository accounts and any deposit account control agreements),
the Senior Agent (or such Senior Lender) shall hold such Collateral as
representative and bailee for the Senior Lenders and the Junior Lender, solely
for the purpose of perfecting the Liens thereon under the Uniform Commercial
Code. Notwithstanding anything to the contrary contained herein, the Senior
Agent (or such Senior Lender) shall not have any duty or liability to protect or
preserve any rights pertaining to any of the Collateral for the Junior Lender
and shall not have by reason of this Agreement a fiduciary relationship to the
Junior Lender or any Junior Lender, and Junior Lender hereby waives and releases
the Senior Agent (or such Senior Lender) from any and all claims and liabilities
arising pursuant to its role as such representative of the Junior Lender.
Promptly following the indefeasible payment in full in cash of the Senior Debt,
the Senior Agent (or such Senior Lender) shall, upon the written request of the
Junior Lender, (i) deliver the remainder of such Collateral, if any, in its
possession to the designee of the Junior Lender (except as may otherwise be
required by applicable law or court order or in connection with a Permitted
Refinance) (ii) as it relates to any deposit account control agreements and/or
lockbox agreements in favor of Senior Agent in relation to the Collateral,
continue to serve as the secured party under such agreements for a reasonable
period of time in accordance with this Section 2.10(a) until Junior Lender and
the applicable loan parties enter into replacement agreements in relation to
such deposit accounts and/or lockbox accounts.
(b)    In the event that the Junior Lender or any Junior Lender takes possession
of or has “control” (as such term is used in the Uniform Commercial Code as in
effect in each applicable jurisdiction) over any Collateral for purposes of
perfecting its Liens therein (including, without limitation, stock certificates
or depository accounts maintained by it), the Junior Lender shall (or shall
cause such Junior Lender to) hold such Collateral as representative and bailee
for the Senior Agent and the Senior Lenders, solely for the purpose of
perfecting the Liens thereon under the UCC. Notwithstanding anything to the
contrary contained herein, the Junior Lender shall not have any duty or
liability to protect or preserve any rights pertaining to any of the Collateral
for the Senior Agent or any Senior Lender and shall not have by reason of this
Agreement a fiduciary relationship to the Senior Agent or any Senior Lender, and
the Senior Agent (or such Senior Lender) hereby waives and releases the Junior
Lender from any and all claims and liabilities arising pursuant to its role as
such representative of the Senior Agent or any Senior Lender. Upon receipt, the

-14-

--------------------------------------------------------------------------------

Junior Lender shall promptly deliver all such Collateral, if any, in its
possession to the Senior Agent.
(c)    It is understood and agreed that this Section 2.10 is intended solely to
assure continuous perfection of the Liens granted under the applicable Senior
Debt Documents and Subordinated Debt Documents, and nothing in this Section 2.10
shall be deemed or construed as altering the priorities or obligations set forth
elsewhere in this Agreement. The duties of each party under this Section 2.10
shall be mechanical and administrative in nature, and no party shall have, or be
deemed to have, by reason of this Section 2.10 a fiduciary relationship in
respect of the other party.
2.11.    Release of Collateral. Without limiting any of the rights (including
without limitation any of the foreclosure rights) of the Senior Lenders or
Senior Agent under the Senior Debt Documents, or any documents delivered to
secure the Obligations of the Loan Parties to Senior Lenders or Senior Agent in
connection therewith or under the provisions of any applicable law, and without
placing any obligation on the part of Senior Agent to follow any of the
following provisions in order to retain its priority status hereunder, in the
event that the Senior Lenders or Senior Agent release or discharge their
security interests (or consent to the release or discharge of their security
interests) in, or Liens upon, any Collateral which is subject to a Lien in favor
of Junior Lender in connection with the sale or other disposition or transfer of
such Collateral in accordance with the terms of the Senior Credit Agreement (as
in effect as of the date of this Agreement), such Collateral shall thereupon be
deemed to have been released from all such Liens in favor of the Junior Lender,
if any. Junior Lender agrees that within ten (10) days following Senior Agent’s
and/or Borrower’s written request therefor, it will execute, deliver and file
any and all such termination statements, Lien releases and other agreements and
instruments as Senior Agent or Borrower reasonably deems necessary or
appropriate in order to give effect to the preceding sentence. Junior Lender
hereby irrevocably appoints Senior Agent the true and lawful attorney of Junior
Lender for the purpose of effecting any such executions, deliveries and filings.
In addition, in the event Senior Agent or Senior Lenders release or discharge
their security interests (or consent to the release or discharge of their
security interest) in, or Lien upon, any Collateral which is subject to a Lien
in favor of Junior Lender in connection with the sale or other disposition or
transfer of the Collateral which is permitted under the terms of the
Subordinated Debt Documents, such Collateral shall thereupon also be deemed to
have been released from all such Liens in favor of the Junior Lender, if any, in
accordance with terms set forth above.
2.12.    Requirement of Notice. Junior Lender agrees to notify Senior Agent
promptly upon obtaining knowledge of the happening of any of the following: (i)
the occurrence of any Subordinated Debt Default or other default under any
Subordinated Debt Document and (ii) the waiver by Junior Lender of any such
Subordinated Debt Default or other default under any of the Subordinated Debt
Documents. Senior Agent agrees to notify Junior Lender promptly upon obtaining
knowledge of the happening of any of the following: (i) the occurrence of any
Senior Default; and (ii) the waiver by Senior Agent of any Senior Default.
2.13.    Right to Purchase Senior Debt.
(a)    If the Senior Debt has been accelerated by the Senior Lenders, or any

-15-

--------------------------------------------------------------------------------

Enforcement Action has been commenced by the Senior Lenders and is continuing
under the Senior Debt Documents (each of the foregoing, a “Purchase Option
Event”), upon ten (10) Business Days prior written notice by Junior Lender to
Senior Agent, which notice shall be, and shall provide that it is, irrevocable
(the “Purchase Notice”), the Junior Lender shall have the right to purchase (the
“Loan Purchase”), in whole but not in part, the Senior Debt as provided herein.
On the date that is specified in the Purchase Notice, which shall not be less
than ten (10) Business Days nor more than fifteen (15) calendar days after
receipt by the Senior Agent of the Purchase Notice (the “Purchase Date”), the
Junior Lender shall purchase from the Senior Lenders all of the Senior Debt for
a purchase price in cash in immediately available funds equal to the Loan
Purchase Price. For purposes of this Agreement, “Loan Purchase Price” shall
equal the outstanding amount of the Senior Debt as of such date of
determination.
(b)    The Loan Purchase shall be consummated pursuant to documentation mutually
acceptable to the parties and shall contain such provisions as are customary in
such documents. Concurrently with payment to an account or accounts designated
by the Senior Agent for the benefit of the Senior Lenders, by wire transfer of
immediately available funds, of the Loan Purchase Price, the Senior Lenders
shall, at the sole cost and expense of the Junior Lender, (i) deliver or cause
to be delivered to Junior Lender, all Senior Debt Documents, as amended and
supplemented, then held by or on behalf of Senior Lenders and (ii) execute in
favor of Junior Lender or its designee, assignment documentation, in form and
substance reasonably acceptable to Junior Lender and the Senior Lenders, to
assign the Senior Debt, the Collateral and the rights of the Senior Lenders
under the Senior Debt Documents (but without recourse and without
representations or warranties of any kind by Senior Agent or any Senior Lender,
except for customary representations as to authority, title, no conflict, the
outstanding balance of the Senior Debt and as to Senior Lenders not having
released, assigned or encumbered any rights in the Collateral or the Senior Debt
Documents).
(c)    Senior Agent shall notify Junior Lender in writing (each such notice, a
“Senior Agent Notice”) following the occurrence of each Purchase Option Event.
(d)    Nothing in this Section shall affect or otherwise restrict any of the
rights or remedies of the Senior Agent or any of the Senior Lenders including,
without limitation, any rights to commence, continue or prosecute any
Enforcement Action related to, or accelerate, the Senior Debt, provided that the
Senior Agent and the Senior Lenders, to the extent they may do so without
prejudice to the rights of the holders of the Senior Debt, shall suspend the
prosecution of any Enforcement Action during the period following their receipt
of a Purchase Notice through the Purchase Date.
3.    Modifications.
3.1.    Modifications to Senior Debt Documents. The Senior Lenders may at any
time and from time to time without the consent of or notice to the Junior
Lender, without incurring liability to the Junior Lender and without impairing
or releasing the obligations of the Junior Lender under this Agreement, change
the manner or place of payment or extend the time of payment of or renew or
alter any of the terms of the Senior Debt, or amend in any manner any agreement,
note, guaranty or other instrument evidencing or securing or otherwise relating
to the Senior Debt; provided that Senior Lenders shall not (i) increase the
interest rate margins, Synthetic Royalty

-16-

--------------------------------------------------------------------------------

Payment requirements, exit fees or prepayment fees, or any other recurring,
monthly, quarterly or annual fees with respect to the Senior Debt that would
result in an increase in the fees and interest payable by Borrower under the
Senior Debt Documents of more than five hundred (500) basis points in the
aggregate (other than as a result of the imposition of interest at the Default
Rate in accordance with the terms of the Senior Debt Documents as in effect as
of the date of this Agreement), or (ii) shorten the final maturity or any other
scheduled payment for principal, interest or any other amount in respect of the
Senior Debt by more than 180 days, (iii) change any redemption or prepayment
provisions of the Senior Debt, except to extend their effective dates, (iv)
increase the principal amount of the Senior Debt other than pursuant to a
Permitted Senior Debt Increase or as otherwise set forth in the definition of
Senior Debt, (v) subordinate the Liens of the Senior Agent on the Collateral
securing the Senior Debt other than in connection with the revolving loan
facility described in Section 3.3 hereof, (vi) add any new financial covenant(s)
or event(s) of default, or modify any existing financial covenant in a manner
that would be more restrictive to Borrower than what is in place as of the date
hereof by more than 10%, (vii) take any additional Liens or security interests
in any assets of the Borrower, any Loan Party or any guarantor of the Senior
Debt to the extent that the Subordinated Debt Documents do not provide for
assets to automatically become subject to the security grant in favor of Junior
Lender and/or Junior Lender otherwise gets a subordinated lien in such assets in
accordance with the priorities set forth in this Agreement, (viii) otherwise
prohibit the payment of the Subordinated Debt other than pursuant to the terms
of this Agreement. The Borrower shall give the Junior Lender prompt written
notice of all amendments, waivers or modifications to, or any new, Senior Debt
Documents. Notwithstanding anything set forth in this Agreement or the
Subordinated Debt Documents to the contrary, there shall be no restrictions on
any voluntary prepayment of the Senior Debt by Borrower that is made in
accordance with the Senior Credit Agreement.
3.2.    Modifications to Subordinated Debt Documents. Until the Senior Debt has
been indefeasibly paid in full in cash (or another form acceptable to the Senior
Agent in writing), and notwithstanding anything to the contrary contained in any
Subordinated Debt Documents, Junior Lender shall not, without the prior written
consent of the Senior Agent, agree to any amendment, modification or supplement
to the Subordinated Debt Documents the effect of which is to (a) increase the
maximum principal amount of the Subordinated Debt; (b) increase the interest
rate with respect to the Subordinated Debt payable upon an Subordinated Debt
Default by more than three hundred (300) basis points; (c) shorten the dates
upon which payments of principal on the Subordinated Debt are due; (d) make more
restrictive, or add, any event of default or any covenant with respect to the
Subordinated Debt; (e) change any redemption or prepayment provisions of the

that would be adverse to the Senior Lenders, including, without limitation,
subordinating the Subordinated Debt to any other indebtedness; (g) take any
additional Liens or security interests in any assets of the Borrower, any Loan
Party or any guarantor of the Subordinated Debt; or (h) change or amend any
other term of the Subordinated Debt Documents if such change or amendment would
result in a Senior Default, materially increase the obligations of the Borrower
(taken as a whole), any Loan Party or any guarantor of the Subordinated Debt or
confer additional material rights on Junior Lender or any other holder of the
Subordinated Debt in a manner materially adverse to the Borrower, any Loan
Party, any such guarantor or the Senior Lenders. Notwithstanding the foregoing,
if the Senior Debt Documents are amended or otherwise

-17-

--------------------------------------------------------------------------------

modified to provide for additional covenants or events of default, or to make
more restrictive or onerous any existing covenants or events of default
applicable to the Loan Parties, then the comparable provisions of the Comparable
Subordinated Debt Documents may be similarly amended or modified to provide for
such additional covenants or events of default or such more restrictive
covenants or events of default, as the case may be, so long as, in each case,
any cushion or step-back between the Senior Debt Documents and the Subordinated
Debt Documents is maintained in connection therewith.
3.3.    Approved AR Loan Facility. The terms and provisions of Section 10.21 of
the Senior Credit Agreement in effect as of the date of this Agreement are
hereby incorporated into this Agreement by reference. In the event that Senior
Agent approves a revolving loan facility in accordance with the terms and

such revolving loan facility is approved by all existing Senior Lenders, (ii) no
Senior Default or Subordinated Debt Default has occurred and is continuing and
(iii) Senior Agent shall not have delivered a Senior Default Notice to Junior
Lender in connection with any blockage of Permitted Subordinated Debt Payments

the Borrower in good faith, and at the Borrower’s sole cost and expense, to
negotiate and enter into such amendments to this Agreement and such Subordinated
Debt Documents as may be necessary, to permit such indebtedness, to release
and/or subordinate such liens as may be necessary to effectuate such revolving
loan facility, and to enter into such third party documents as may be reasonably
requested by Borrower and/or such revolving loan lender.
4.    Intercreditor Provisions.
4.1.    Management of Collateral. Subject to the other terms and conditions of
this Agreement including, without limitation, the rights of the Junior Lender
under Section 2.4, until the Senior Debt has been indefeasibly paid in full in
cash (or another form acceptable to the Senior Agent in writing) , and both
inside and outside of a Proceeding, the Senior Agent, and the Senior Lenders or
any representative thereof in the manner provided in the Senior Debt Documents,
shall have the exclusive right to manage, perform and enforce the terms of the
Senior Debt Documents and the other Documents with respect to any Collateral, to
exercise and enforce all privileges and rights thereunder and with respect
thereto, according to their sole and absolute discretion and the exercise of
their business judgment, including, without limitation, the exclusive right to
take or retake control or possession of any Collateral and to hold, prepare for
sale, process, sell, lease, foreclose upon, dispose of, collect, or liquidate
any Collateral and to incur expenses in connection with any of the foregoing,
including, without limitation, in connection with such sale or disposition and
to exercise any and all of the rights and remedies of a secured lender under the
Uniform Commercial Code of any applicable jurisdiction. In furtherance and not
in limitation of the foregoing, Junior Lender waives any and all rights to
direct the method of any action by any holder of Senior Debt (or any
representative thereof) in connection with, and any right to object to, a strict
foreclosure with respect to any Collateral, waives any and all rights of
redemption and hereby consents to each holder of Senior Debt (or any
representative thereof) dealing in all respects with the Collateral as if there
were no Liens on the Collateral securing the Subordinated Debt; provided,
however, that nothing herein shall constitute a waiver the Junior Lender’s right
to object to or assert

-18-

--------------------------------------------------------------------------------

that a private or public sale conducted by the Senior Agent was commercially
unreasonable. In conducting any public or private sale under the Uniform
Commercial Code, the Senior Agent shall give the Junior Lender such notice of
such sale as may be required by the applicable Uniform Commercial Code;
provided, however, that ten (10) days’ notice shall be deemed to be commercially
reasonable notice.
4.2.    Permitted Actions. Subject in all respects to the terms of this
Agreement, nothing contained herein shall be construed to limit or impair in any
way the right of: (a) any Secured Creditor to bid for or purchase Collateral at
any private or judicial foreclosure upon such Collateral initiated by any
Secured Creditor; (b) any Secured Creditor to join (but not control) any
foreclosure or other judicial Lien enforcement proceeding with respect to the
Collateral initiated by any other Secured Creditor for the sole purpose of
protecting such Secured Creditor’s Lien on the Collateral, so long as it does
not delay, hinder or interfere with the exercise by the such other Secured
Creditor of its rights under this Agreement, the Documents or any applicable
law; and (c) the Junior Lender to receive any remaining proceeds of Collateral
after the Senior Debt has been indefeasibly paid in full in cash (or another
form acceptable to the Senior Agent in writing) and all commitments to lend or
otherwise extend credit under the Senior Debt Documents have irrevocably
terminated in writing.
4.3.    Marshaling and Similar Rights. The Junior Lender hereby waives any
rights it may have under applicable law to assert the doctrine of marshaling or
to otherwise require the Senior Lenders to marshal any property of the Borrower,
any other Loan Party or any guarantor of the Senior Debt for the benefit of a
Junior Lender. Until the indefeasible payment in full in cash (or another form
which the Senior Agent has indicated in writing is acceptable) of the Senior
Debt, the Junior Lender further agrees not to demand, request, plead or
otherwise claim the benefit of, any appraisement, valuation or other similar
right that may otherwise be available under applicable law.
5.    Representations and Warranties

Senior Debt, the Junior Lender shall be subrogated to the rights of the Senior
Lenders to receive Distributions with respect to the Senior Debt until the
Subordinated Debt is paid in full and shall not assert or be entitled to enforce
any such subrogation rights. The Junior Lender agrees that in the event that all
or any part of a payment made with respect to the Senior Debt is recovered from
the holders of the Senior Debt in a Proceeding or otherwise, any Distribution
