(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).

(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.

The Senior Agent shall promptly deliver a written notice to the Junior Lender after waiver or cure of any Senior Default.

(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 2.3shall not be construed as preventing the occurrence of a Subordinated Debt Default under the applicable Subordinated Debt Documents; and

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 thisSection 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 Subordinated Debt, except to extend their effective dates; (f) alter the subordination provisions with respect to the Subordinated Debt in any manner 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 provisions of such Section 10.21 of the Senior Credit Agreement, Junior Lender shall (a) be deemed to have approved such revolving loan facility so long as (i) 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 pursuant to Section 2.3(a) hereof, and (b) work together with Senior Agent and 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.

-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

The Junior Lender hereby represents and warrants to the Senior Agent that (a) it is a limited liability company duly formed and validly existing under the laws of the State of Delaware (b) it has the power and authority to enter into, execute, deliver and carry out the terms of this Agreement, all of which have been duly authorized by all proper and necessary action; (c) the execution of this Agreement by the Junior Lender will not violate or conflict with the organizational documents of the Junior Lender, any material agreement binding upon the Junior Lender or any law, regulation or order or require any consent or approval which has not been obtained; (d) this Agreement is the legal, valid and binding obligation of the Junior Lender, enforceable against the Junior Lender in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by equitable principles; and (e) the Junior Lender is the sole owner, beneficially and of record, of the Subordinated Debt.

5.2.Representations and Warranties of the Senior Agent. The Senior Agent hereby represents and warrants to the Junior Lender that as of the date hereof: (a) it is a limited

-19-

liability company duly formed and validly existing under the laws of the State of Delaware; (b) it has the power and authority to enter into, execute, deliver and carry out the terms of this Agreement, all of which have been duly authorized by all proper and necessary action; (c) the execution of this Agreement by it will not violate or conflict with its organizational documents, any material agreement binding upon it or any law, regulation or order or require any consent or approval which has not been obtained; (d) this Agreement is the legal, valid and binding obligation of it, enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles; and (e) the Senior Agent and the Senior Creditors are the sole owners, beneficially and of record, of the Senior Debt.

6.Subrogation. Subject to the indefeasible payment in full in cash of all 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 received by the Junior Lender with respect to the Subordinated Debt at any time after the date of the payment that is so recovered, whether pursuant to the right of subrogation provided for in this Agreement or otherwise, shall be deemed to have been received by the Junior Lender in trust as property of the holders of the Senior Debt and the Junior Lender shall forthwith segregate and deliver the same to the Senior Agent for application to the Senior Debt until the Senior Debt is indefeasibly paid in full in cash (or another form which the Senior Agent has indicated in writing is acceptable). Notwithstanding any other provision of this Agreement to the contrary, a Distribution made pursuant to this Agreement to the Senior Agent which otherwise would have been made to Junior Lender is not, as between the Borrower, any other Loan Party and Junior Lender, a payment by the Borrower or such other Loan Party to or on account of the Senior Debt.

7.Entire Agreement; Modification. This Agreement evidences the entire agreement of the parties regarding the ordering of interests set forth herein, and all prior oral discussions and writings are merged into this Agreement. Any modification or waiver of any provision of this Agreement, or any consent to any departure by any party from the terms hereof, shall not be effective in any event unless the same is in writing and signed by the Senior Agent, the Junior Lender and the Loan Parties, and then such modification, waiver or consent shall be effective only in the specific instance and for the specific purpose given. Any notice to or demand on any party hereto in any event not specifically required hereunder shall not entitle the party receiving such notice or demand to any other or further notice or demand in the same, similar or other circumstances unless specifically required hereunder.

8.Sharing of Information. The Borrower and each other Loan Party irrevocably consents to the sharing among the Senior Agent, the Senior Lenders and the Junior Lender of any information they may now or hereafter have regarding the Borrower and the other Loan Parties, subject to the agreement of each of the Senior Lenders and the Junior Lender pursuant to the Senior Debt Documents and the Subordinated Debt Documents, as applicable, to maintain such information as confidential. This provision does not evidence or suggest any duty on the part of the Senior

-20-

Lenders or the Junior Lender to share such information.

9.Further Assurances. Each party to this Agreement will promptly execute and deliver such further instruments and agreements and do such further acts and things as may be reasonably requested in writing by any other party hereto that may be necessary or desirable in order to effect fully the purposes of this Agreement.
