Such Grantor agrees that, if it shall acquire any interest in any Commercial Tort Claim with a value in excess of $500,000 (whether from another Person or because such Commercial Tort Claim shall have come into existence), (i) such Grantor shall, promptly upon such acquisition, deliver to the Administrative Agent, in each case in form and substance satisfactory to the Administrative Agent, a notice of the existence and nature of such Commercial Tort Claim and deliver a supplement to Schedule 5 (Commercial Tort Claims) containing a specific description of such Commercial Tort Claim, (ii) the provision of Section 2.1 (Collateral) shall apply to such Commercial Tort Claim and (iii) such Grantor shall execute and deliver to the Administrative Agent, in each case in form and substance satisfactory to the Administrative Agent, any certificate, agreement and other document, and take all other action, deemed by the Administrative Agent to be reasonably necessary or appropriate for the Administrative Agent to obtain, on behalf of the Lenders, a first-priority perfected security interest in all such Commercial Tort Claims. Any supplement to Schedule 5 (Commercial Tort Claims) delivered pursuant to this Section 4.10 (Notice of Commercial Tort Claims) shall, after the receipt thereof by the Administrative Agent, become part of Schedule 5 (Commercial Tort Claims) for all purposes hereunder other than in respect of representations and warranties made prior to the date of such receipt.

ARTICLE V Remedial Provisions

Section 5.1 Code and Other Remedies

During the continuance of an Event of Default, the Administrative Agent 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 Secured Obligations, all rights and remedies of a secured party under the UCC or any other applicable law. Without limiting the generality of the foregoing, the Administrative Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived to the extent permitted by applicable law), may in such circumstances forthwith collect, receive, appropriate

Pledge and Security Agreement

and realize upon any Collateral, and may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver any Collateral (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Administrative Agent or any Lender or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Administrative Agent shall have the right upon any such public sale or sales, and, to the extent permitted by the UCC and other applicable law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption of any Grantor, which right or equity is hereby waived and released. Each Grantor further agrees, at the Administrative Agent’s request, to assemble the Collateral and make it available to the Administrative Agent at places that the Administrative Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. The Administrative Agent shall apply the net proceeds of any action taken by it pursuant to this Section 5.1, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any Collateral or in any way relating to the Collateral or the rights of the Administrative Agent and any other Secured Party hereunder, including reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Secured Obligations, in such order as the Credit Agreement shall prescribe, and only after such application and after the payment by the Administrative Agent of any other amount required by any provision of law, need the Administrative Agent account for the surplus, if any, to any Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against the Administrative Agent or any other Secured Party arising out of the exercise by them of any rights hereunder, except as relating to or arising out of the gross negligence or willful misconduct of the Administrative Agent or such other Secured Party. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition.

Section 5.2 Accounts and Payments in Respect of General Intangibles

(a) In addition to, and not in substitution for, any similar requirement in the Credit Agreement, if required by the Administrative Agent at any time during the continuance of an Event of Default, any payment of Accounts or payment in respect of General Intangibles, when collected by any Grantor, shall be forthwith (and, in any event, within two Business Days deposited by such Grantor (or, as applicable, duly indorsed by such Grantor to the Administrative Agent), in a Cash Collateral Account or as otherwise directed by the Administrative Agent by written notice. Until so turned over or turned over, such payment shall be held by such Grantor in trust for the Administrative Agent, segregated from other funds of such Grantor. Each such deposit of Proceeds of Accounts and payments in respect of General Intangibles shall be accompanied by a report identifying in reasonable detail the nature and source of the payments included in the deposit.

(b) At the Administrative Agent’s request, during the continuance of an Event of Default, each Grantor shall deliver to the Administrative Agent all original and other documents evidencing, and relating to, the agreements and transactions that gave rise to the Accounts or payments in respect of General Intangibles, including all original orders, invoices and shipping receipts.

Pledge and Security Agreement
Orbital Sciences Corporation

(c) The Administrative Agent may, without notice, at any time during the continuance of an Event of Default, limit or terminate the authority of a Grantor to collect its Accounts or amounts due under General Intangibles or any thereof.

(d) The Administrative Agent in its own name or in the name of others may at any time during the continuance of an Event of Default communicate with Account Debtors to verify with them to the Administrative Agent’s satisfaction the existence, amount and terms of any Account or amounts due under any General Intangible.

(e) Upon the request of the Administrative Agent at any time during the continuance of an Event of Default, each Grantor shall notify Account Debtors that the Accounts or General Intangibles have been collaterally assigned to the Administrative Agent and that payments in respect thereof shall be made directly to the Administrative Agent. In addition, the Administrative Agent may at any time during the continuance of an Event of Default enforce such Grantor’s rights against such Account Debtors and obligors of General Intangibles.

(f) Anything herein to the contrary notwithstanding, each Grantor shall remain liable under each of the Accounts and payments in respect of General Intangibles to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto. Neither the Administrative Agent nor any other Secured Party shall have any obligation or liability under any agreement giving rise to an Account or a payment in respect of a General Intangible by reason of or arising out of this Agreement or the receipt by the Administrative Agent or any other Secured Party of any payment relating thereto, nor shall the Administrative Agent nor any other Secured Party be obligated in any manner to perform any obligation of any Grantor under or pursuant to any agreement giving rise to an Account or a payment in respect of a General Intangible, to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts that may have been assigned to it or to which it may be entitled at any time or times.

Section 5.3 Pledged Collateral

(a) During the continuance of an Event of Default, upon notice by the Administrative Agent to the relevant Grantor or Grantors, (i) the Administrative Agent shall have the right to receive any Proceeds of the Pledged Collateral and make application thereof to the Obligations in the order set forth in the Credit Agreement and (ii) the Administrative Agent or its nominee may exercise (A) any voting, consent, corporate and other right pertaining to the Pledged Collateral at any meeting of shareholders, partners or members, as the case may be, of the relevant issuer or issuers of Pledged Collateral or otherwise and (B) any right of conversion, exchange and subscription and any other right, privilege or option pertaining to the Pledged Collateral as if it were the absolute owner thereof (including the right to exchange at its discretion any of the Pledged Collateral upon the merger, amalgamation, consolidation, reorganization, recapitalization or other fundamental change in the corporate or equivalent structure of any issuer of Pledged Stock, the right to deposit and deliver any Pledged Collateral with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Administrative Agent may determine), all without liability except to account for property actually received by it; provided, however, that the Administrative Agent shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

Pledge and Security Agreement
Orbital Sciences Corporation

(b) In order to permit the Administrative Agent to exercise the voting and other consensual rights that it may be entitled to exercise pursuant hereto and to receive all dividends and other distributions that it may be entitled to receive hereunder, (i) each Grantor shall promptly execute and deliver (or cause to be executed and delivered) to the Administrative Agent all such proxies, dividend payment orders and other instruments as the Administrative Agent may from time to time reasonably request and (ii) without limiting the effect of clause (i) above, such Grantor hereby grants to the Administrative Agent an irrevocable proxy to vote all or any part of the Pledged Collateral and to exercise all other rights, powers, privileges and remedies to which a holder of the Pledged Collateral would be entitled (including giving or withholding written consents of shareholders, partners or members, as the case may be, calling special meetings of shareholders, partners or members, as the case may be, and voting at such meetings), which proxy shall be effective, automatically and without the necessity of any action (including any transfer of any Pledged Collateral on the record books of the issuer thereof) by any other person (including the issuer of such Pledged Collateral or any officer or agent thereof) during the continuance of an Event of Default and which proxy shall only terminate upon the payment in full of the Secured Obligations.

(c) Each Grantor hereby expressly authorizes and instructs each issuer of any Pledged Collateral pledged hereunder by such Grantor to (i) comply with any instruction received by it from the Administrative Agent in writing that (A) states that an Event of Default has occurred and is continuing and (B) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Grantor, and each Grantor agrees that such issuer shall be fully protected in so complying and (ii) unless otherwise expressly permitted hereby, pay any dividend or other payment with respect to the Pledged Collateral directly to the Administrative Agent.

Section 5.4 Registration Rights

(a) Each Grantor recognizes that the Administrative Agent may be unable to effect a public sale of any Pledged Collateral by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise or may determine that a public sale is impracticable or not commercially reasonable and, accordingly, may resort to one or more private sales thereof to a restricted group of purchasers that shall be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Administrative Agent shall be under no obligation to delay a sale of any Pledged Collateral for the period of time necessary to permit the issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such issuer would agree to do so.

(b) Each Grantor agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Collateral pursuant to this Section 5.4 valid and binding and in compliance with all other applicable Requirements of Law. Each Grantor further agrees that a breach of any covenant contained in this Section 5.4 will cause irreparable injury to the Administrative Agent and other Secured Parties, that the Administrative Agent and the other Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 5.4 shall be specifically enforceable against such Grantor, and such

Pledge and Security Agreement
Orbital Sciences Corporation

Grantor hereby waives and agrees not to assert any defense against an action for specific performance of such covenants except for a defense that no Event of Default has occurred under the Credit Agreement.

Section 5.5 Deficiency

Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Secured Obligations. Any surplus remaining after the full payment and satisfaction of the Secured Obligations shall be returned to such Grantor or to whomsoever a court of competent jurisdiction shall determine to be entitled thereto.

ARTICLE VI The Administrative Agent

Section 6.1 Administrative Agent’s Appointment as Attorney-in-Fact

(a) Each Grantor hereby irrevocably constitutes and appoints the Administrative Agent 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 such Grantor and in the name of such Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any appropriate action and to execute any document or instrument that may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Administrative Agent the power and right, on behalf of such Grantor, without notice to or assent by such Grantor, to do any of the following:

(i) in the name of such Grantor or its own name, or otherwise, take possession of and indorse and collect any check, draft, note, acceptance or other instrument for the payment of moneys due under any Account or General Intangible or with respect to any other Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Administrative Agent for the purpose of collecting any such moneys due under any Account or General Intangible or with respect to any other Collateral whenever payable;

(ii) in the case of any Intellectual Property, execute and deliver, and have recorded, any agreement, instrument, document or paper as the Administrative Agent may deem appropriate to evidence the Administrative Agent’s security interest in such Intellectual Property and the goodwill and General Intangibles of such Grantor relating thereto or represented thereby;

(iii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repair or pay any insurance called for by the terms of this Agreement (including all or any part of the premiums therefor and the costs thereof);

(iv) execute, in connection with any sale provided for in Section 5.1 (Code and Other Remedies) or Section 5.4 (Registration Rights), any endorsement, assignment or other instrument of conveyance or transfer with respect to the Collateral; and

(v) (A) direct any party liable for any payment under any Collateral to make payment of any moneys due or to become due thereunder directly to the Administrative

Pledge and Security Agreement
Orbital Sciences Corporation

Agent or as the Administrative Agent shall direct, (B) ask or demand for, collect, and receive payment of and receipt for, any moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral, (C) sign and indorse any invoice, freight or express xxxx, xxxx of lading, storage or warehouse receipt, draft against debtors, assignment, verification, notice and other document in connection with any Collateral, (D) commence and prosecute any suit, action or proceeding at law or in equity in any court of competent jurisdiction to collect any Collateral and to enforce any other right in respect of any Collateral, (E) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral, (F) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Administrative Agent may deem appropriate, (G) assign any Copyright, Patent or Trademark (along with the goodwill of the business to which any such Trademark pertains) throughout the world for such term or terms, on such conditions, and in such manner as the Administrative Agent shall in its sole discretion determine, including the execution and filing of any document necessary to effectuate or record such assignment and (H) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any Collateral as fully and completely as though the Administrative Agent were the absolute owner thereof for all purposes and do, at the Administrative Agent’s option and such Grantor’s expense, at any time, or from time to time, all acts and things that the Administrative Agent deems necessary to protect, preserve or realize upon the Collateral and the Administrative Agent’s and the other Secured Parties’ security interests therein and to effect the intent of this Agreement, all as fully and effectively as such Grantor might do.

Anything in this clause (a) to the contrary notwithstanding, the Administrative Agent agrees that it shall not exercise any right under the power of attorney provided for in this clause (a) unless an Event of Default shall be continuing.

(b) If any Grantor fails to perform or comply with any of its agreements contained herein, the Administrative Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

(c) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

Section 6.2 Duty of Administrative Agent

The Administrative Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession shall be to deal with it in the same manner as the Administrative Agent deals with similar property for its own account. None of the Administrative Agent, any other Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to any Collateral. The powers conferred on the Administrative Agent hereunder are solely to protect the Administrative Agent’s interest in the Collateral and shall not impose any duty upon the Administrative Agent or any other Secured Party to exercise any such powers. The Administrative Agent and the other Secured Parties shall be accountable only for

Pledge and Security Agreement
Orbital Sciences Corporation

amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their respective officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

Section 6.3 Authorization of Financing Statements

Each Grantor authorizes the Administrative Agent and its Affiliates, counsel and other representatives, at any time and from time to time, to file or record financing statements, amendments to financing statements, and other filing or recording documents or instruments with respect to the Collateral in such form and in such offices as the Administrative Agent reasonably determines appropriate to perfect the security interests of the Administrative Agent under this Agreement. Such financing statements and amendments may describe the Collateral covered thereby as “all assets of the debtor”, “all personal property of the debtor” or words of similar effect; provided, however, that if requested by the Borrower, any such financing statement or amendment shall specifically identify any Excluded Property that is not subject thereto. Each Grantor hereby also authorizes the Administrative Agent and its Affiliates, counsel and other representatives, at any time and from time to time, to file continuation statements with respect to previously filed financing statements. A photographic or other reproduction of this Agreement shall be sufficient as a financing statement or other filing or recording document or instrument for filing or recording in any jurisdiction.

Section 6.4 Authority of Administrative Agent

Each Grantor acknowledges that the rights and responsibilities of the Administrative Agent under this Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Administrative Agent and the other Secured Parties, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Administrative Agent and the Grantors, the Administrative Agent shall be conclusively presumed to be acting as agent for the Administrative Agent and the other Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

ARTICLE VII Miscellaneous

Section 7.1 Amendments in Writing

None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 11.1 (Amendments, Waivers, Etc.) of the Credit Agreement; provided, however, that annexes to this Agreement may be supplemented (but no existing provisions may be modified and no Collateral may be released) through Pledge Amendments and Joinder Agreements, in substantially the form of Annex 1 (Form of Pledge Amendment) and Annex 2 (Form of Joinder Agreement) respectively, in each case duly executed by the Administrative Agent and each Grantor directly affected thereby.

Section 7.2 Notices

Pledge and Security Agreement
Orbital Sciences Corporation

All notices, requests and demands to or upon the Administrative Agent or any Grantor hereunder shall be effected in the manner provided for in Section 11.8 (Notices, Etc.) of the Credit Agreement; provided, however, that any such notice, request or demand to or upon any Grantor shall be addressed to the Borrower’s notice address set forth in such Section 11.8.

Section 7.3 No Waiver by Course of Conduct; Cumulative Remedies

Neither the Administrative Agent nor any other Secured Party shall by any act (except by a written instrument pursuant to Section 7.1 (Amendments in Writing)), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor any delay in exercising, on the part of the Administrative Agent or any other Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Administrative Agent or any other Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Administrative Agent or such other Secured Party would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

Section 7.4 Successors and Assigns

This Agreement shall be binding upon the successors and assigns of each Grantor and shall inure to the benefit of the Administrative Agent and each other Secured Party and their successors and assigns; provided, however, that no Grantor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent.

Section 7.5 Counterparts

This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by telecopy), each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Signature pages may be detached from multiple counterparts and attached to a single counterpart so that all signature pages are attached to the same document. Delivery of an executed counterpart by telecopy shall be effective as delivery of a manually executed counterpart.

Section 7.6 Severability

Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Section 7.7 Section Headings

Pledge and Security Agreement
Orbital Sciences Corporation

The Article and Section titles contained in this Agreement are, and shall be, without substantive meaning or content of any kind whatsoever and are not part of the agreement of the parties hereto.

Section 7.8 Entire Agreement

Section 7.10 Additional Grantors

If, pursuant to Section 7.9 (Subsidiaries) of the Credit Agreement, the Borrower shall be required to cause any Subsidiary that is not a Grantor to become a Grantor hereunder, such Subsidiary shall execute and deliver to the Administrative Agent a Joinder Agreement substantially in the form of Annex 2 (Form of Joinder Agreement) and shall thereafter for all purposes be a party hereto and have the same rights, benefits and obligations as a Grantor party hereto on the Closing Date.

Section 7.11 Release of Collateral

(a) At the time provided in Section 10.8(b)(i) (Concerning the Collateral and the Collateral Documents) of the Credit Agreement, the Collateral shall be released from the Lien created hereby and this Agreement and all obligations (other than those expressly stated to survive such termination) of the Administrative Agent and each Grantor hereunder shall terminate, all without delivery of any instrument or performance of any act by any party, and all rights to the Collateral shall revert to the Grantors. At the request and sole expense of any Grantor following any such termination, the Administrative Agent shall deliver to such Grantor any Collateral of such Grantor held by the Administrative Agent hereunder and execute and deliver to such Grantor such documents as such Grantor shall reasonably request to evidence such termination.

(b) If the Administrative Agent shall be directed or permitted pursuant to Section 10.8(b)(ii) or (iii) (Concerning the Collateral and the Collateral Documents) of the Credit Agreement to release any Lien created hereby upon any Collateral (including any Collateral sold or disposed of by any Grantor in a transaction permitted by the Credit Agreement), such Collateral shall, at the request of the Borrower, be released from the Lien created hereby to the extent permitted pursuant to the terms and conditions set forth in, Section 10.8(b)(ii) or (iii) (Concerning the Collateral and the Collateral Documents) of the Credit Agreement. In connection therewith, the Administrative Agent, at the request and sole expense of the Borrower, shall execute and deliver to the Borrower all releases or other documents, including, without limitation, UCC termination statements, reasonably necessary or desirable for the release of the Lien created hereby on such Collateral. At the request and sole expense of the Borrower, a Grantor shall be released from its obligations hereunder in the event that all the capital stock of such Grantor shall be sold or disposed or such Grantor shall be dissolved or liquidated; provided,

Pledge and Security Agreement
Orbital Sciences Corporation

however, that the Borrower shall have delivered to the Administrative Agent, at least five Business Days (or such shorter period as permitted by the Administrative Agent) prior to the date of the proposed release, a written request for release identifying the relevant Grantor and the terms of the sale or other disposition in reasonable detail, together with a certification by the Borrower in form and substance satisfactory to the Administrative Agent stating that such transaction is in compliance with the Credit Agreement and the other Loan Documents.

Section 7.12 Reinstatement

Each Grantor further agrees that, if any payment made by any Loan Party or other Person and applied to the Obligations is at any time annulled, avoided, set aside, rescinded, invalidated, declared to be fraudulent or preferential or otherwise required to be refunded or repaid, or the proceeds of Collateral are required to be returned by any Secured Party to such Loan Party, its estate, trustee, receiver or any other party, including any Grantor, under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, any Lien or other Collateral securing such liability shall be and remain in full force and effect, as fully as if such payment had never been made or, if prior thereto the Lien granted hereby or other Collateral securing such liability hereunder shall have been released or terminated by virtue of such cancellation or surrender, such Lien or other Collateral shall be reinstated in full force and effect, and such prior cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect any Lien or other Collateral securing the obligations of any Grantor in respect of the amount of such payment.
