Within the limits of the Commitment of each Revolving Credit Lender, amounts of Revolving Loans repaid may be reborrowed under this Section 2.1.

(b) Additional Commitments. The Borrower may at any time, upon prior written notice by the Borrower to the Administrative Agent, increase the Commitments by up to $75,000,000 with additional Commitments from any existing Lender or new Commitments from any other Person selected by the Borrower and approved by the Administrative Agent (which approval shall not be unreasonably withheld or delayed); provided that:

Section 2.2 Borrowing Procedures

(a) Each Borrowing shall be made on notice given by the Borrower to the Administrative Agent not later than 11:00 a.m. (New York time) (i) on the date of the proposed Borrowing, in the case of a Borrowing of Base Rate Loans and (ii) three Business Days prior to the date of the proposed Borrowing, in the case of a Borrowing of Eurodollar Rate Loans. Each such notice shall be in substantially the form of Exhibit C (Form of Notice of Borrowing) (a “Notice of Borrowing”), specifying, (A) the date of such proposed Borrowing, (B) the aggregate amount of such proposed Borrowing, (C) whether any portion of the proposed Borrowing will be of Base Rate Loans or Eurodollar Rate Loans and (D) for each Eurodollar Rate Loan, the initial Interest Period or Periods thereof. Loans shall be made as Base Rate Loans unless, subject to Section 2.14 (Special Provisions Governing Eurodollar Rate Loans), the Notice of Borrowing specifies that all or a portion thereof shall be Eurodollar Rate Loans. Notwithstanding anything to the contrary contained in Section 2.3(a) (Swing Loans), if any Notice of Borrowing requests a Borrowing of Base Rate Loans, the Administrative Agent may make a Swing Loan available to the Borrower in an aggregate amount not to exceed such proposed Borrowing, and the aggregate amount of the corresponding proposed Borrowing shall be reduced accordingly by the principal amount of such Swing Loan. Each Borrowing shall be in an aggregate amount of not less than $1,000,000 or an integral multiple of $500,000 in excess thereof. The Borrower may not request more than four Borrowings per month.

(b) The Administrative Agent shall give to each Lender prompt notice of the Administrative Agent’s receipt of a Notice of Borrowing and, if Eurodollar Rate Loans are properly requested in such Notice of Borrowing, the applicable interest rate determined pursuant to Section 2.14(a) (Determination of Interest Rate). Each Lender shall, before 1:00 p.m. (New York time) on the date of the proposed Borrowing, make available to the Administrative Agent at its address referred to in Section 11.8 (Notices, Etc.), in immediately available funds, such Lender’s Ratable Portion of such proposed Borrowing. Upon fulfillment (or due waiver in accordance with Section 11.1 (Amendments, Waivers, Etc.)) (i) on the Closing Date, of the applicable conditions set forth Section 3.1 (Conditions Precedent to Initial Loans and Letters of Credit) and (ii) at any time (including the Closing Date), of the applicable conditions set forth in Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit), and after the Administrative Agent’s receipt of such funds, the Administrative Agent shall make such funds available to the Borrower.

(c) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any proposed Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Ratable Portion of such Borrowing (or any portion

Credit Agreement

thereof), the Administrative Agent may assume that such Lender has made such Ratable Portion available to the Administrative Agent on the date of such Borrowing in accordance with this Section 2.2 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such Ratable Portion available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate for the first Business Day and thereafter at the interest rate applicable at the time to the Loans comprising such Borrowing. If such Lender shall repay to the Administrative Agent such corresponding amount, such corresponding amount so repaid shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement. If the Borrower shall repay to the Administrative Agent such corresponding amount, such payment shall not relieve such Lender of any obligation it may have hereunder to the Borrower.

(d) The failure of any Lender to make on the date specified any Loan or any payment required by it (such Lender being a “Non-Funding Lender”), including any payment in respect of its participation in Swing Loans and Letter of Credit Obligations, shall not relieve any other Lender of its obligations to make such Loan or payment on such date but no such other Lender shall be responsible for the failure of any Non-Funding Lender to make a Loan or payment required under this Agreement.

Each Swing Loan shall be a Base Rate Loan and must be repaid in full within seven days after its making or, if sooner, upon any Borrowing hereunder and shall in any event mature no later than the Termination Date. Within the limits set forth in the first sentence of this clause (a), amounts of Swing Loans repaid may be reborrowed under this clause (a).

(b) In order to request a Swing Loan, the Borrower shall telecopy (or forward by electronic mail or similar means) to the Administrative Agent a duly completed request in substantially the form of Exhibit D (Form of Swing Loan Request), setting forth the requested amount and date of such Swing Loan (a “Swing Loan Request”), to be received by the Administrative Agent not later than 3:00 p.m. (New York time) on the day of the proposed borrowing.

Upon such payment by a Revolving Credit Lender, such Revolving Credit Lender shall, except as provided in clause (f) below, be deemed to have made a Revolving Loan to the Borrower. The Administrative Agent shall use such funds to repay the Swing Loans to the Swing Loan Lender. To the extent that any Revolving Credit Lender fails to make such payment available to the Administrative Agent for the account of the Swing Loan Lender, the Borrower shall repay such Swing Loan on demand.

(b) Any Letter of Credit with a term less than or equal to one year may provide for the renewal thereof for additional periods less than or equal to one year, as long as, on or before the expiration of each such term and each such period, the Issuer of such Letter or Credit shall have the option to prevent such renewal. Any Letter of Credit with an expiration date beyond the date that is five days prior to the Scheduled Termination Date shall, in the case of such a Letter of Credit where Citibank is the Issuer, be subject to a Letter of Credit Reimbursement Agreement of continuing effect and in the form required by the applicable Issuer and shall be subject to the actions required by Section 9.3 (Actions in Respect of Letters of Credit); provided, however, that neither the Issuer of such Letter of Credit nor the Borrower shall permit any such Letter of Credit to be denominated in any currency other than Dollars.

(c) In connection with the Issuance of each Letter of Credit, the Borrower shall give the relevant Issuer and the Administrative Agent at least two Business Days’ prior

Credit Agreement
Orbital Sciences Corporation

written notice, in substantially the form of Exhibit E (Form of Letter of Credit Request) (or in such other written or electronic form as is acceptable to the Issuer), of the requested Issuance of such Letter of Credit (a “Letter of Credit Request”). Such notice shall be irrevocable and shall specify the Issuer of such Letter of Credit, the currency of issuance and face amount of the Letter of Credit requested (whose Dollar Equivalent shall not be less than $10,000), the date of Issuance of such requested Letter of Credit, the date on which such Letter of Credit is to expire (which date shall be a Business Day) and, in the case of an issuance, the Person in whose favor the requested Letter of Credit is to be issued, which may include foreign commercial banks which have issued letters of credit or bank guarantees on behalf of the Borrower or any of its Subsidiaries. Such notice, to be effective, must be received by the relevant Issuer and the Administrative Agent not later than 11:00 a.m. (New York time) on the second Business Day prior to the requested Issuance of such Letter of Credit.

(d) Subject to the satisfaction of the conditions set forth in this Section 2.4, the relevant Issuer shall, on the requested date, Issue a Letter of Credit on behalf of the Borrower in accordance with such Issuer’s usual and customary business practices. No Issuer shall Issue any Letter of Credit in the period commencing on the first Business Day after it receives written notice from any Revolving Credit Lender that one or more of the conditions precedent contained in Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit) or clause (a) above (other than those conditions set forth in clauses (a)(i), (a)(vi)(B) and (C) above and, to the extent such clause relates to fees owing to the Issuer of such Letter of Credit and its Affiliates, clause (a)(vi)(A) above) are not on such date satisfied or duly waived and ending when such conditions are satisfied or duly waived. No Issuer shall otherwise be required to determine that, or take notice whether, the conditions precedent set forth in Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit) have been satisfied in connection with the Issuance of any Letter of Credit.

(e) The Borrower agrees that, if requested by the Issuer of any Letter of Credit, it shall execute a Letter of Credit Reimbursement Agreement in the form required by the applicable Issuer in respect to any Letter of Credit Issued hereunder. In the event of any conflict between the terms of any Letter of Credit Reimbursement Agreement and this Agreement, the terms of this Agreement shall govern.

(f) Each Issuer shall comply with the following:

(i) give the Administrative Agent written notice (or telephonic notice confirmed promptly thereafter in writing), which writing may be a telecopy or electronic mail, of the Issuance of any Letter of Credit Issued by it, of all drawings under any Letter of Credit Issued by it and of the payment (or the failure to pay when due) by the Borrower of any Reimbursement Obligation when due (which notice the Administrative Agent shall promptly transmit by telecopy, electronic mail or similar transmission to each Revolving Credit Lender);

(ii) upon the request of any Revolving Credit Lender, furnish to such Revolving Credit Lender copies of any Letter of Credit Reimbursement Agreement to which such Issuer is a party and such other documentation as may reasonably be requested by such Revolving Credit Lender; and

(iii) no later than 10 Business Days following the last day of each calendar quarter, provide to the Administrative Agent (and the Administrative Agent

Credit Agreement
Orbital Sciences Corporation

shall provide a copy to each Revolving Credit Lender requesting the same) and the Borrower separate schedules for Documentary Letters of Credit and Standby Letters of Credit issued by it, in form and substance reasonably satisfactory to the Administrative Agent, setting forth the aggregate Letter of Credit Obligations, in each case outstanding at the end of each calendar quarter and any information requested by the Borrower or the Administrative Agent relating thereto.

(g) Immediately upon the issuance by an Issuer of a Letter of Credit in accordance with the terms and conditions of this Agreement, such Issuer shall be deemed to have sold and transferred to each Revolving Credit Lender, and each Revolving Credit Lender shall be deemed irrevocably and unconditionally to have purchased and received from such Issuer, without recourse or warranty, an undivided interest and participation, to the extent of such Revolving Credit Lender’s Ratable Portion of the Commitments, in such Letter of Credit and the obligations of the Borrower with respect thereto (including all Letter of Credit Obligations with respect thereto) and any security therefor and guaranty pertaining thereto.

(h) The Borrower agrees to pay to the Issuer of any Letter of Credit the amount of all Reimbursement Obligations owing to such Issuer under any Letter of Credit issued for its account no later than the date that payment has been made under such Letter of Credit(as notified by the Issuer to the Borrower) (the “Reimbursement Date”), irrespective of any claim, set-off, defense or other right that the Borrower may have at any time against such Issuer or any other Person. In the event that any Issuer makes any payment under any Letter of Credit and the Borrower shall not have repaid such amount to such Issuer pursuant to this clause (h) or any such payment by the Borrower is rescinded or set aside for any reason, the Administrative Agent shall promptly notify each Revolving Credit Lender of the Reimbursement Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Revolving Credit Lender’s Ratable Portion thereof. In such event, the Borrower shall be deemed to have requested a borrowing of Base Rate Loans to be disbursed on the Reimbursement Date in an amount equal to the Unreimbursed Amount (or, if the time for requesting a borrowing of Base Rate Loans on such date has passed, the Borrower shall be deemed to have so requested a borrowing of Swing Loans, or if the time for requesting a borrowing of Base Rate Loans and Swing Loans on such date has passed, then the Borrower shall be deemed to have so requested a borrowing of Base Rate Loans on the succeeding Business Day) without regard to the minimum and multiples specified in Section 2.2(a)(Borrowing Procedures) or the conditions contained in Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit); provided, however, that if such Base Rate Loan is made after the Reimbursement Date, interest shall be payable on demand and shall accrue from the Reimbursement Date to the date of making such Base Rate Loan for the account of the applicable Issuer at the rate of interest applicable during such period to past due Revolving Loans that are Base Rate Loans. Such Reimbursement Obligation shall be payable on demand with interest thereon computed, to the extent not funded by a Base Rate Loan or Swing Loan as described above, from the date on which such Reimbursement Obligation arose until the date of repayment in full, at the rate of interest applicable during such period to past due Revolving Loans that are Base Rate Loans, and such Issuer shall promptly notify the Administrative Agent, which shall promptly notify each Revolving Credit Lender of such failure, and each Revolving Credit Lender shall promptly and unconditionally pay to the Administrative Agent for the account of such Issuer the amount of such Revolving Credit Lender’s Ratable Portion of such payment (or the Dollar Equivalent thereof if such payment was made in any currency other than Dollars) in immediately available Dollars. If the Administrative Agent so notifies such Revolving Credit Lender prior to 11:00 a.m. (New York time) on any Business Day, each Revolving Credit Lender

Credit Agreement
Orbital Sciences Corporation

shall make available to the Administrative Agent for the account of such Issuer its Ratable Portion of the amount of such payment on such Business Day in immediately available funds. Upon such payment by a Revolving Credit Lender, such Revolving Credit Lender shall notwithstanding whether or not the conditions precedent set forth in Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit) shall have been satisfied (which conditions precedent the Revolving Credit Lenders hereby irrevocably waive), be deemed to have made a Revolving Loan to the Borrower in the principal amount of such payment. Whenever any Issuer receives from the Borrower a payment of a Reimbursement Obligation as to which the Administrative Agent has received for the account of such Issuer any payment from a Revolving Credit Lender pursuant to this clause (h), such Issuer shall pay over to the Administrative Agent any amount received in excess of such Reimbursement Obligation and, upon receipt of such amount, the Administrative Agent shall promptly pay over to each Revolving Credit Lender, in immediately available funds, an amount equal to such Revolving Credit Lender’s Ratable Portion of the amount of such payment adjusted, if necessary, to reflect the respective amounts the Revolving Credit Lenders have paid in respect of such Reimbursement Obligation.

(i) If and to the extent any Revolving Credit Lender shall not have so made its Ratable Portion of the amount of the payment required by clause (h) above available to the Administrative Agent for the account of such Issuer, such Revolving Credit Lender agrees to pay to the Administrative Agent for the account of such Issuer forthwith on demand any such unpaid amount together with interest thereon, for the first Business Day after payment was first due at the Federal Funds Rate and, thereafter, until such amount is repaid to the Administrative Agent for the account of such Issuer, at a rate per annum equal to the rate applicable to Base Rate Loans under the Facility.

(j) The Borrower’s obligation to pay each Reimbursement Obligation and the obligations of the Revolving Credit Lenders to make payments to the Administrative Agent for the account of the Issuers with respect to Letters of Credit shall be absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement, under any and all circumstances whatsoever and irrespective of any of the following:

(i) any lack of validity or enforceability of any Letter of Credit or any Loan Document, or any term or provision therein;

(ii) any amendment or waiver of or any consent to departure from all or any of the provisions of any Letter of Credit or any Loan Document;

(iii) the existence of any claim, set-off, defense or other right that the Borrower, any other party guaranteeing, or otherwise obligated with, the Borrower, any Subsidiary or other Affiliate thereof or any other Person may at any time have against the beneficiary under any Letter of Credit, any Issuer, the Administrative Agent or any Lender or any other Person, whether in connection with this Agreement, any other Loan Document or any other related or unrelated agreement or transaction;

(iv) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

Credit Agreement
Orbital Sciences Corporation

(v) payment by the Issuer under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit;

(vi) any other act or omission to act or delay of any kind of the Issuer, the Lenders, the Administrative Agent or any other Person or any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.4, constitute a legal or equitable discharge of the Borrower’s obligations hereunder; and

(vii) any failure to satisfy any conditions precedent set forth in Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit) or the occurrence of any Default or Event of Default under any Loan Document.

Any action taken or omitted to be taken by the relevant Issuer under or in connection with any Letter of Credit, if taken or omitted in the absence of gross negligence or willful misconduct, shall not result in any liability of such Issuer to the Borrower or any Lender. In determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof, the Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary and, in making any payment under any Letter of Credit, the Issuer may rely exclusively on the documents presented to it under such Letter of Credit as to any and all matters set forth therein, including reliance on the amount of any draft presented under such Letter of Credit, whether or not the amount due to the beneficiary thereunder equals the amount of such draft and whether or not any document presented pursuant to such Letter of Credit proves to be insufficient in any respect, if such document on its face appears to be in order, and whether or not any other statement or any other document presented pursuant to such Letter of Credit proves to be forged or invalid or any statement therein proves to be inaccurate or untrue in any respect whatsoever, and any noncompliance in any immaterial respect of the documents presented under such Letter of Credit with the terms thereof shall, in each case, be deemed not to constitute willful misconduct or gross negligence of the Issuer.

(k) Schedule 2.4 (Existing Letters of Credit) contains a schedule of certain letters of credit issued prior to the Closing Date under the Existing Credit Agreement for the account of the Borrower. On the Closing Date (i) such letters of credit, to the extent outstanding, shall be automatically and without further action by the parties thereto converted to Letters of Credit issued pursuant to this Section 2.4 for the account of the Borrower and subject to the provisions hereof, and for this purpose the fees specified in Section 2.12(b)(ii)(Fees) shall be payable (in substitution for any fees set forth in the applicable letter of credit reimbursement agreements or applications relating to such letters of credit) as if such letters of credit had been issued on the Closing Date, it being understood that no fees shall become payable pursuant to Section 2.12(b)(i)(Fees) in connection with such letters of credit, (ii) the issuers of such Letters of Credit shall be deemed to be “Issuers” hereunder, (iii) the face amount of such letters of credit shall be included in the calculation of Letter of Credit Obligations and (iv) all liabilities of the Borrower with respect to such letters of credit shall constitute Obligations.

(l) Cash Collateral Account. The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuers and the Lenders, a security interest in all cash, deposit accounts and all balances therein and all proceeds of the foregoing as required to be deposited in furtherance of Section 2.9(Mandatory Prepayments) and Section 9.3(Actions in

Credit Agreement
Orbital Sciences Corporation

Respect of Letters of Credit). Cash collateral shall be maintained in blocked, interest bearing deposit accounts at Citibank. All interest on such cash collateral shall be paid as follows: (i) if such cash collateral is delivered to the Administrative Agent by the Borrower pursuant to any of Section 2.9(Mandatory Prepayments) or Section 9.3(Actions in Respect of Letters of Credit), then such interest shall be paid to the Borrower upon the Borrower’s request, provided that such interest shall first be applied to all outstanding Obligations at such time and the balance shall be distributed to the Borrower, and (ii) if such cash collateral is delivered to the Administrative Agent by the Borrower at any time that such cash collateral is not required to be delivered under this Agreement, then such interest shall be distributed to the Borrower (provided that if at any time after such delivery of cash collateral the Borrower would have been required to deliver cash collateral pursuant to any of Sections 2.9 or 9.3, the interest shall be applied as provided in clause (i) above).

(m) Notwithstanding anything set forth in this Agreement to the contrary, the obligations of each Revolving Credit Lender under Sections 2.4(h) and (i) above shall not be affected by the occurrence of the Termination Date or the termination of the Commitments.

(n) Unless otherwise expressly agreed by the applicable Issuer and the Borrower when a Letter of Credit is issued (including any such agreement applicable to an existing letter of credit), (i) the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) (the “ISP”) shall apply to each Standby Letter of Credit and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance, shall apply to each Documentary Letter of Credit. For all purposes of this Agreement, if on any date of determination, a Letter of Credit has expired by its terms but any amount may still be drawn thereunder by reason of the operation of Rule 3.14 of the ISP, the applicable Issuer shall notify the Administrative Agent thereof and such Letter of Credit shall be deemed to be “outstanding” in the amount so remaining available to be drawn.

Section 2.5 Reduction and Termination of the Commitments

The Borrower may, upon at least three Business Days’ prior notice to the Administrative Agent, terminate in whole or reduce in part ratably the unused portions of the respective Commitments of the Revolving Credit Lenders; provided, however, that each partial reduction shall be in an aggregate amount of not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof. Subject to Section 2.4(m)(Letters of Credit), all outstanding Commitments shall terminate on the Termination Date.

Section 2.6 Repayment of Loans

The Borrower promises to repay the entire unpaid principal amount of the Revolving Loans and the Swing Loans on the Scheduled Termination Date or earlier, if otherwise required by the terms hereof; provided, however, that any Revolving Loans and Swing Loans made after the Termination Date pursuant to Section 2.4(h)(Letters of Credit) shall be payable on demand as required by the terms thereof.

Section 2.7 Evidence of Debt

(a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing Indebtedness of the Borrower to such Lender resulting from each Loan of such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

(b) (i) The Administrative Agent, acting as agent of the Borrower solely for this purpose and for tax purposes, shall establish and maintain at its address referred to in Section 11.8 (Notices, Etc.) a record of ownership (the “Register”) in which the Administrative Agent agrees to register by book entry the Administrative Agent’s, each Lender’s and each Issuer’s interest in each Loan, each Letter of Credit and each Reimbursement Obligation, and in the right to receive any payments hereunder and any assignment of any such interest or rights. In addition, the Administrative Agent, acting as agent of the Borrower solely for this purpose and for tax purposes, shall establish and maintain accounts in the Register in accordance with its usual practice in which it shall record (i) the names and addresses of the Lenders and the Issuers, (ii) the Commitments of each Lender from time to time, (iii) the amount of each Loan made and, if a Eurodollar Rate Loan, the Interest Period applicable thereto, (iv) the amount of any principal or interest due and payable, and paid, by the Borrower to, or for the account of, each Lender hereunder, (v) the amount that is due and payable, and paid, by the Borrower to, or for the account of, each Issuer, including the amount of Letter Credit Obligations (specifying the amount of any Reimbursement Obligations) due and payable to an Issuer, and (vi) the amount of any sum received by the Administrative Agent hereunder from the Borrower, whether such sum constitutes principal or interest (and the type of Loan to which it applies), fees, expenses or other amounts due under the Loan Documents and each Lender’s and Issuer’s, as the case may be, share thereof, if applicable.

(i) Notwithstanding anything to the contrary contained in this Agreement, the Loans (including the Notes evidencing such Loans) and the Reimbursement Obligations are registered obligations and the right, title, and interest of the Lenders and the Issuers and their assignees in and to such Loans or Reimbursement Obligations, as the case may be, shall be transferable only upon notation of such transfer in the Register. A Note shall only evidence the Lender’s or a registered assignee’s right, title and interest in and to the related Loan, and in no event is any such Note to be considered a bearer instrument or obligation. This Section 2.7(b) and Section 11.2 shall be construed so that the Loans and Reimbursement Obligations are at all times maintained in “registered form” within the meaning of Sections 163(f), 871(h)(2) and 881(c)(2) of the Code and any related regulations (or any successor provisions of the Code or such regulations).

(c) The entries made in the Register and in the accounts therein maintained pursuant to clauses (a) and (b) above shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations recorded therein; provided, however, that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrower to repay the Loans in accordance with their terms. In addition, the Loan Parties, the Administrative Agent, the Lenders and the Issuers shall treat each Person whose name is recorded in the Register as a Lender or as an Issuer, as applicable, for all purposes of this Agreement. Information contained in the Register with respect to any Lender or Issuer shall be available for inspection by the

Credit Agreement
Orbital Sciences Corporation

Borrower, the Administrative Agent, such Lender or such Issuer at any reasonable time and from time to time upon reasonable prior notice.

(d) Notwithstanding any other provision of the Agreement, in the event that any Lender requests that the Borrower execute and deliver a promissory note or notes payable to such Lender in order to evidence the Indebtedness owing to such Lender by the Borrower hereunder, the Borrower shall promptly execute and deliver a Note or Notes to such Lender evidencing any Revolving Loans of such Lender, substantially in the forms of Exhibit B (Form of Note).

Section 2.8 Optional Prepayments

(a) The Borrower may prepay the outstanding principal amount of the Revolving Loans and Swing Loans in whole or in part at any time; provided, however, that if any prepayment of any Eurodollar Rate Loan is made by the Borrower other than on the last day of an Interest Period for such Loan, the Borrower shall also pay any amount owing pursuant to Section 2.14(e) (Breakage Costs).

(b) The Borrower shall have no right to prepay the principal amount of any Revolving Loan other than as provided in this Section 2.8.

Section 2.9 Mandatory Prepayments

If at any time prior to the Termination Date, the aggregate principal amount of Revolving Credit Outstandings exceeds the aggregate Commitments at such time, the Borrower shall forthwith prepay the Swing Loans first and then the Revolving Loans then outstanding in an amount equal to such excess. If any such excess remains after repayment in full of the aggregate outstanding Swing Loans and Revolving Loans, the Borrower shall provide cash collateral for the Letter of Credit Obligations in the manner set forth in Section 9.3 (Actions in Respect of Letters of Credit) in an amount equal to 100% of such excess.

Section 2.10 Interest

(a) Rate of Interest. All Loans and the outstanding amount of all other Obligations (other than pursuant to any Swap Contracts or Cash Management Document that are Loan Documents, which shall not be subject to any additional economic obligations on the part of Borrower or its Subsidiaries that are not specified in such agreements), shall bear interest, in the case of Loans, on the unpaid principal amount thereof from the date such Loans are made and, in the case of such other Obligations, from the date such other Obligations are due and payable until, in all cases, paid in full, except as otherwise provided in clause (c) below, as follows:

(i) if a Base Rate Loan or such other Obligation, at a rate per annum equal to the sum of (A) the Base Rate as in effect from time to time and (B) the Applicable Margin for Revolving Loans that are Base Rate Loans; and

(ii) if a Eurodollar Rate Loan, at a rate per annum equal to the sum of (A) the Eurodollar Rate determined for the applicable Interest Period and (B) the Applicable Margin in effect from time to time during such Interest Period.

Credit Agreement
Orbital Sciences Corporation

(b) Interest Payments. (i) Interest accrued on each Base Rate Loan (other than Swing Loans) shall be payable in arrears (A) on the first Business Day of each calendar quarter, commencing on the first such day following the making of such Base Rate Loan and (B) if not previously paid in full, at maturity (whether by acceleration or otherwise) of such Base Rate Loan, (ii) interest accrued on Swing Loans shall be payable in arrears on the first Business Day of the immediately succeeding calendar quarter, (iii) interest accrued on each Eurodollar Rate Loan shall be payable in arrears (A) on the last day of each Interest Period applicable to such Loan and, if such Interest Period has a duration of more than three months, on each date during such Interest Period occurring every three months from the first day of such Interest Period, (B) upon the payment or prepayment thereof in full or in part and (C) if not previously paid in full, at maturity (whether by acceleration or otherwise) of such Eurodollar Rate Loan and (iv) interest accrued on the amount of all other Obligations shall be payable on demand from and after the time such Obligation becomes due and payable (whether by acceleration or otherwise).

(c) Default Interest. Notwithstanding the rates of interest specified in clause (a) above or elsewhere herein, effective immediately upon the occurrence of an Event of Default and for as long thereafter as such Event of Default shall be continuing, the principal balance of all Loans and the amount of all other Obligations then due and payable shall bear interest at a rate that is two percent per annum in excess of the rate of interest applicable to such Loans or other Obligations from time to time. Such interest shall be payable on the date that would otherwise be applicable to such interest pursuant to cause (b) above or otherwise on demand.

Section 2.11 Conversion/Continuation Option

(a) The Borrower may elect (i) at any time on any Business Day to convert Base Rate Loans (other than Swing Loans) or any portion thereof to Eurodollar Rate Loans and (ii) at the end of any applicable Interest Period, to convert Eurodollar Rate Loans or any portion thereof into Base Rate Loans or to continue such Eurodollar Rate Loans or any portion thereof for an additional Interest Period; provided, however, that the aggregate amount of the Eurodollar Loans for each Interest Period must be in the amount of at least $1,000,000 or an integral multiple of $500,000 in excess thereof. Each conversion or continuation shall be allocated among the Loans of each Lender in accordance with such Lender’s Ratable Portion. Each such election shall be in substantially the form of Exhibit F (Form of Notice of Conversion or Continuation) (a “Notice of Conversion or Continuation”) and shall be made by giving the Administrative Agent at least three Business Days’ prior written notice specifying (A) the amount and type of Loan being converted or continued, (B) in the case of a conversion to or a continuation of Eurodollar Rate Loans, the applicable Interest Period and (C) in the case of a conversion, the date of such conversion.

(b) The Administrative Agent shall promptly notify each Lender of its receipt of a Notice of Conversion or Continuation and of the options selected therein. Notwithstanding the foregoing, no conversion in whole or in part of Base Rate Loans to Eurodollar Rate Loans and no continuation in whole or in part of Eurodollar Rate Loans upon the expiration of any applicable Interest Period shall be permitted at any time at which (A) a Default or an Event of Default shall have occurred and be continuing or (B) the continuation of, or conversion into, a Eurodollar Rate Loan would violate any provision of Section 2.14 (Special Provisions Governing Eurodollar Rate Loans). If, within the time period required under the terms of this Section 2.11, the Administrative Agent does not receive a Notice of Conversion or Continuation from the Borrower containing a permitted election to continue any Eurodollar Rate

Credit Agreement
Orbital Sciences Corporation

Loans for an additional Interest Period or to convert any such Loans, then, upon the expiration of the applicable Interest Period, such Loans shall be automatically converted to Base Rate Loans. Each Notice of Conversion or Continuation shall be irrevocable.

Section 2.12 Fees

(a) Unused Commitment Fee. The Borrower agrees to pay in immediately available Dollars to each Revolving Credit Lender a commitment fee on the actual daily amount by which the Commitment of such Revolving Credit Lender exceeds such Lender’s Ratable Portion of the sum of (i) the aggregate outstanding principal amount of Revolving Loans and (ii) the outstanding amount of the aggregate Letter of Credit Obligations (the “Unused Commitment Fee”) from the date hereof through the Termination Date at the Applicable Unused Commitment Fee Rate, payable in arrears (x) on the first Business Day of each calendar quarter, commencing on the first such Business Day following the Closing Date and (y) on the Termination Date.

(b) Letter of Credit Fees. The Borrower agrees to pay the following amounts with respect to Letters of Credit issued by any Issuer:

(i) directly to the account of each Issuer of a Letter of Credit, with respect to each Letter of Credit issued by such Issuer, such issuance or fronting fees in the amounts and at the times as may be agreed from time to time between the Borrower and such Issuer.

(ii) to the Administrative Agent for the ratable benefit of the Revolving Credit Lenders, with respect to each Letter of Credit, a fee accruing each day in Dollars at a rate per annum equal to the Applicable Margin for Revolving Loans that are Eurodollar Rate Loans on the amount available to be drawn on that day under such Letter of Credit on any date of determination, payable in arrears as follows: (A) Letter of Credit fees equal to fifty basis points (0.50%) per annum times the amount available to be drawn on that day under such Letter of Credit shall be due and payable on the first Business Day of each calendar quarter, commencing on the first such Business Day following the issuance of such Letter of Credit, and on the last to occur of (1) the Termination Date and (2) the first date following the Termination Date on which the aggregate of all Letter of Credit Obligations equals zero and (B) the balance of the Letter of Credit fees owing in respect of such Letters of Credit shall be payable on the first Business Day of each calendar year and on the first date following the Termination Date on which the aggregate of all Letter of Credit Obligations equals zero. If there is any change in the Applicable Margin during any quarter, the daily amount of each Letter of Credit shall be computed and multiplied by the Applicable Margin separately for each period during such quarter that such Applicable Margin was in effect. On each day during the continuance of an Event of Default, the Applicable Margin applicable to the foregoing Letter of Credit fees shall be increased by two percent per annum (instead of, and not in addition to, any increase pursuant to Section 2.10(c) (Interest)) and shall be payable on demand.

(iii) to the Issuer of any Letter of Credit, with respect to the issuance, amendment or transfer of each Letter of Credit and each drawing made thereunder, documentary and processing charges in accordance with such Issuer’s standard schedule for such charges in effect at the time of issuance, amendment, transfer or drawing, as the case may be.

(c) Additional Fees. The Borrower has agreed to pay to the Administrative Agent and the Arranger additional fees, the amount and dates of payment of which are embodied in the Fee Letter.

Section 2.13 Payments and Computations

(a) The Borrower shall make each payment hereunder (including fees and expenses) not later than 11:00 a.m. (New York time) on the day when due, in the currency specified herein (or, if no such currency is specified, in Dollars) to the Administrative Agent at its address referred to in Section 11.8 (Notices, Etc.) in immediately available funds without set-off or counterclaim. The Administrative Agent shall promptly thereafter cause to be distributed immediately available funds relating to the payment of principal, interest or fees to the Lenders, in accordance with the application of payments set forth in clause (f) or (g) below, as applicable, for the account of their respective Applicable Lending Offices; provided, however, that amounts payable pursuant to Section 2.15 (Capital Adequacy), Section 2.16 (Taxes)or Section 2.14(c) or (d) (Special Provisions Governing Eurodollar Rate Loans)shall be paid only to the affected Lender or Lenders and amounts payable with respect to Swing Loans shall be paid only to the Swing Loan Lender. Payments received by the Administrative Agent after 11:00 a.m. (New York time) shall be deemed to be received on the next Business Day.

(b) All computations of interest and of fees shall be made by the Administrative Agent on the basis of a year of 360 days, or, in the case of interest in respect of Loans which are Base Rate Loans, on the basis of a year of 365 or 366 days, as the case may be and actual days elapsed, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest and fees are payable. Each determination by the Administrative Agent of a rate of interest hereunder shall be conclusive and binding for all purposes, absent manifest error.

(c) Each payment by the Borrower of any Loan, Reimbursement Obligation (including interest or fees in respect thereof) and each reimbursement of various costs, expenses or other Obligation shall be made in the currency in which such Loan was made, such Letter of Credit issued or such cost, expense or other Obligation was incurred; provided, however, that (i) the Letter of Credit Reimbursement Agreement for a Letter of Credit may specify another currency for the Reimbursement Obligation in respect of such Letter of Credit and (ii) other than for payments in respect of a Loan or Reimbursement Obligation, Loan Documents duly executed by the Administrative Agent or any Swap Contract may specify other currencies of payment for Obligations created by or directly related to such Loan Document or Swap Contract.

(d) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of any Eurodollar Rate Loan to be made in the next calendar month, such payment shall be made on the immediately preceding Business Day. All repayments of any Revolving Loans shall be applied as follows: first, to repay such Loans outstanding as Base Rate Loans and then, to repay such Loans outstanding as Eurodollar Rate Loans, with those Eurodollar Rate Loans having earlier expiring Eurodollar Interest Periods being repaid prior to those having later expiring Eurodollar Interest Periods.

(e) Unless the Administrative Agent shall have received notice from the Borrower to the Lenders prior to the date on which any payment is due hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon (at the Federal Funds Rate for the first Business Day and thereafter, at the rate applicable to Base Rate Loans) for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent.

(f) Except for payments and other amounts received by the Administrative Agent and applied in accordance with the provisions of clause (g) below (or required to be applied in accordance with Section 2.9 (Mandatory Prepayments)), all payments and any other amounts received by the Administrative Agent from or for the benefit of the Borrower shall be applied as follows: first, to pay principal of, and interest on, any portion of the Loans the Administrative Agent may have advanced pursuant to the express provisions of this Agreement on behalf of any Lender, for which the Administrative Agent has not then been reimbursed by such Lender or the Borrower, second, to pay all other Obligations then due and payable and third, as the Borrower so designates. Payments in respect of Swing Loans received by the Administrative Agent shall be distributed to the Swing Loan Lender; payments in respect of Revolving Loans received by the Administrative Agent shall be distributed to each Revolving Credit Lender in accordance with such Lender’s Ratable Portion of the Commitments; and all payments of fees and all other payments in respect of any other Obligation shall be allocated among such of the Lenders and Issuers as are entitled thereto and, for such payments allocated to the Lenders, in proportion to their respective Ratable Portions.

(g) The Borrower hereby irrevocably waives the right to direct the application of any and all payments in respect of the Obligations and any proceeds of Collateral after the occurrence and during the continuance of an Event of Default and agrees that, notwithstanding clause (f) above, the Administrative Agent may, and, upon either (A) the written direction of the Requisite Lenders or (B) the acceleration of the Obligations pursuant to Section 9.2 (Remedies) shall apply all payments in respect of any Obligations and all proceeds of Collateral in the following order:

(i) first, to pay interest on and then principal of any portion of the Revolving Loans that the Administrative Agent may have advanced on behalf of any Lender for which the Administrative Agent has not then been reimbursed by such Lender or the Borrower;

(ii) second, to pay Secured Obligations in respect of any expense reimbursements or indemnities then due to the Administrative Agent, the Lenders and the Issuers;

(iii) third, to pay Secured Obligations in respect of any fees then due to the Administrative Agent, the Lenders and the Issuers;

(iv) fourth, to pay interest then due and payable in respect of the Loans and Reimbursement Obligations;

(v) fifth, to pay or prepay principal amounts on the Loans and Reimbursement Obligations and to provide cash collateral for outstanding Letter of Credit Undrawn Amounts in the manner described in Section 9.3 (Actions in Respect of Letters of Credit), and to pay Cash Management Obligations and amounts owing with respect to Swap Contracts, ratably to the aggregate principal amount of such Loans, Reimbursement Obligations and Letter of Credit Undrawn Amounts, Cash Management Obligations, and Obligations owing with respect to Swap Contracts; and

(vi) sixth, to the ratable payment of all other Secured Obligations;

provided, however, that if sufficient funds are not available to fund all payments to be made in respect of any Secured Obligation described in any of clauses (i), (ii), (iii), (iv), (v) and (vi) above, the available funds being applied with respect to any such Secured Obligation (unless otherwise specified in such clause) shall be allocated to the payment of such Secured Obligation ratably, based on the proportion of the Administrative Agent’s and each Lender’s or Issuer’s interest in the aggregate outstanding Secured Obligations described in such clauses; provided, however, that payments that would otherwise be allocated to the Revolving Credit Lenders shall be allocated first to repay Swing Loans until such Loans are repaid in full and then to repay the Revolving Loans. The order of priority set forth in clauses (i), (ii), (iii), (iv), (v) and (vi) above may at any time and from time to time be changed by the agreement of the Requisite Lenders without necessity of notice to or consent of or approval by the Borrower, any Secured Party that is not a Lender or Issuer or by any other Person that is not a Lender or Issuer. The order of priority set forth in clauses (i), (ii) and (iii) above may be changed only with the prior written consent of the Administrative Agent in addition to that of the Requisite Lenders.

Section 2.14 Special Provisions Governing Eurodollar Rate Loans

(a) Determination of Interest Rate

The Eurodollar Rate for each Interest Period for Eurodollar Rate Loans shall be determined by the Administrative Agent pursuant to the procedures set forth in the definition of “Eurodollar Rate.” The Administrative Agent’s determination shall be presumed to be correct absent manifest error and shall be binding on the Borrower.

(b) Interest Rate Unascertainable, Inadequate or Unfair

In the event that (i) the Administrative Agent determines that adequate and fair means do not exist for ascertaining the applicable interest rates by reference to which the Eurodollar Rate then being determined is to be fixed or (ii) the Requisite Lenders notify the Administrative Agent that the Eurodollar Rate for any Interest Period will not adequately reflect the cost to the Lenders of making or maintaining such Loans for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon each Eurodollar Loan shall automatically, on the last day of the current Interest Period for such Loan, convert into a Base Rate Loan and the obligations of the Lenders to make Eurodollar Rate Loans or to convert Base Rate Loans into Eurodollar Rate Loans shall be suspended until the Administrative Agent shall notify the Borrower that the Requisite Lenders have determined that the circumstances causing such suspension no longer exist.

Credit Agreement
Orbital Sciences Corporation

If at any time any Lender determines that the introduction of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order (other than any change by way of imposition or increase of reserve requirements included in determining the Eurodollar Rate) or the compliance by such Lender with any guideline, request or directive from any central bank or other Governmental Authority (whether or not having the force of law), shall have the effect of increasing the cost to such Lender of agreeing to make or making, funding or maintaining any Eurodollar Rate Loans, then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost; provided, however, that before making any such demand, each Lender agrees to use commercially reasonable efforts (consistent with its legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. A certificate as to the amount of such increased cost, submitted to the Borrower and the Administrative Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error.

(d) Illegality

Notwithstanding any other provision of this Agreement, if any Lender determines that the introduction of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order after the date of this Agreement shall make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful, for any Lender or its Eurodollar Lending Office to make Eurodollar Rate Loans or to continue to fund or maintain Eurodollar Rate Loans, then, on notice thereof and demand therefor by such Lender to the Borrower through the Administrative Agent, (i) the obligation of such Lender to make or to continue Eurodollar Rate Loans and to convert Base Rate Loans into Eurodollar Rate Loans shall be suspended, and each such Lender shall make a Base Rate Loan as part of any requested Borrowing of Eurodollar Rate Loans and (ii) if the affected Eurodollar Rate Loans are then outstanding, the Borrower shall immediately convert each such Loan into a Base Rate Loan; provided, however, that before making any such demand, each Lender agrees to use commercially reasonable efforts (consistent with its legal and regulatory restrictions) to designate a different Eurodollar Lending Office if the making of such a designation would allow such Lender or its Eurodollar Lending Office to continue to perform its obligations to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate Loans and would not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. If, at any time after a Lender gives notice under this clause (d), such Lender determines that it may lawfully make Eurodollar Rate Loans, such Lender shall promptly give notice of that determination to the Borrower and the Administrative Agent, and the Administrative Agent shall promptly transmit the notice to each other Lender. The Borrower’s right to request, and such Lender’s obligation, if any, to make Eurodollar Rate Loans shall thereupon be restored.

(e) Breakage Costs

In addition to all amounts required to be paid by the Borrower pursuant to Section 2.10 (Interest), the Borrower shall compensate each Lender, upon demand, for all losses, expenses and liabilities (including any loss or expense incurred by reason of the liquidation or

Credit Agreement
Orbital Sciences Corporation

reemployment of deposits or other funds acquired by such Lender to fund or maintain such Lender’s Eurodollar Rate Loans to the Borrower but excluding any loss of the Applicable Margin on the relevant Loans) that such Lender may sustain (i) if for any reason (other than solely by reason of such Lender being a Non-Funding Lender) a proposed Borrowing, conversion into or continuation of Eurodollar Rate Loans does not occur on a date specified therefor in a Notice of Borrowing or a Notice of Conversion or Continuation given by the Borrower or in a telephonic request by it for borrowing or conversion or continuation or a successive Interest Period does not commence after notice therefor is given pursuant to Section 2.11 (Conversion/Continuation Option), (ii) if for any reason any Eurodollar Rate Loan is prepaid (including mandatorily pursuant to Section 2.9 (Mandatory Prepayments)) on a date that is not the last day of the applicable Interest Period, (iii) as a consequence of a required conversion of a Eurodollar Rate Loan to a Base Rate Loan as a result of any of the events indicated in clause (d) above, (iv) as a consequence of any failure by the Borrower to repay Eurodollar Rate Loans when required by the terms hereof or (v) as a result of any deemed sale and purchase of participations pursuant to an increase in the Commitments in accordance with Section 2.1(b)(Additional Commitments). The Lender making demand for such compensation shall deliver to the Borrower concurrently with such demand a written statement as to such losses, expenses and liabilities, and this statement shall be conclusive as to the amount of compensation due to such Lender, absent manifest error.

Section 2.15 Capital Adequacy

If at any time any Lender determines that (a) the adoption of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order after the date of this Agreement regarding capital adequacy, (b) compliance with any such law, treaty, rule, regulation or order or (c) compliance with any guideline or request or directive from any central bank or other Governmental Authority (whether or not having the force of law) shall have the effect of reducing the rate of return on such Lender’s (or any corporation controlling such Lender’s) capital as a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change, compliance or interpretation, then, upon demand from time to time by such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to the Administrative Agent for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender for such reduction. A certificate as to such amounts submitted to the Borrower and the Administrative Agent by such Lender shall be conclusive and binding for all purposes absent manifest error.

Section 2.16 Taxes

(a) Except as otherwise provided in this Section 2.16, any and all payments by any Loan Party under each Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding (i) in the case of each Lender, each Issuer and the Administrative Agent (A) taxes measured by its net income, and franchise taxes imposed on it, and similar taxes imposed by the jurisdiction (or any political subdivision thereof) under the laws of which such Lender, such Issuer or the Administrative Agent (as the case may be) is organized and (B) any U.S. withholding taxes payable with respect to payments under the Loan Documents under laws (including any statute, treaty or regulation) in effect on the Closing Date (or, in the case of (x) an Eligible Assignee, the date of the Assignment and Acceptance, (y) a successor Administrative Agent, the date of the appointment of such Administrative Agent, and (z) a successor Issuer, the date such Issuer becomes an Issuer) applicable to such Lender, such

Issuer or the Administrative Agent, as the case may be, but not excluding any U.S. withholding taxes payable as a result of any change in such laws occurring after the Closing Date (or the date of such Assignment and Acceptance or the date of such appointment of such Administrative Agent or the date such Issuer becomes an Issuer) and (ii) in the case of each Lender or each Issuer, taxes measured by its net income, and franchise taxes imposed on it as a result of a present or former connection between such Lender or such Issuer (as the case may be) and the jurisdiction of the Governmental Authority imposing such tax or any taxing authority thereof or therein (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If any Taxes shall be required by law to be deducted from or in respect of any sum payable under any Loan Document to any Lender, any Issuer or the Administrative Agent (w) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.16, such Lender, such Issuer or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (x) the relevant Loan Party shall make such deductions, (y) the relevant Loan Party shall pay the full amount deducted to the relevant taxing authority or other authority in accordance with applicable law and (z) the relevant Loan Party shall deliver to the Administrative Agent evidence of such payment.

(b) In addition, each Loan Party agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies of the United States or any political subdivision thereof or any applicable foreign jurisdiction, and all liabilities with respect thereto, in each case arising from any payment made under any Loan Document or from the execution, delivery or registration of, or otherwise with respect to, any Loan Document (collectively, “Other Taxes”).

(c) Each Loan Party shall, jointly and severally, indemnify each Lender, each Issuer and the Administrative Agent for the full amount of Taxes and Other Taxes (including any Taxes and Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.16) paid by such Lender, such Issuer or the Administrative Agent (as the case may be) and any liability (including for penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within 30 days from the date such Lender, such Issuer or the Administrative Agent (as the case may be) makes written demand therefor.

(d) Within 30 days after the date of any payment of Taxes or Other Taxes by any Loan Party, the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 11.8 (Notices, Etc.), the original or a certified copy of a receipt evidencing payment thereof.

(e) Without prejudice to the survival of any other agreement of any Loan Party hereunder or under the Guaranty, the agreements and obligations of such Loan Party contained in this Section 2.16 shall survive the payment in full of the Obligations.

(f) (i) Each Non-U.S. Lender that is entitled to an exemption from U.S. withholding tax, or that is subject to such tax at a reduced rate under an applicable tax treaty, shall (v) on or prior to the Closing Date in the case of each Non-U.S. lender that is a signatory hereto, (w) on or prior to the date of the Assignment and Acceptance pursuant to which such Non-U.S. Lender becomes a Lender the date a successor Issuer becomes an Issuer or the date a successor Administrative Agent becomes the

Administrative Agent hereunder, (x) on or prior to the date on which any such form or certification expires or becomes obsolete, (y) after the occurrence of any event requiring a change in the most recent form or certification previously delivered by it to the Borrower and the Administrative Agent, and (z) from time to time if requested by the Borrower or the Administrative Agent, provide the Administrative Agent and the Borrower with two completed originals of each of the following, as applicable:

(A) Form W-8ECI (claiming exemption from U.S. withholding tax because the income is effectively connected with a U.S. trade or business) or any successor form;

(B) Form W-8BEN (claiming exemption from, or a reduction of, U.S. withholding tax under an income tax treaty) or any successor form;

(C) in the case of a Non-U.S. Lender claiming exemption under Sections 871(h) or 881(c) of the Code, a Form W-8BEN (claiming exemption from U.S. withholding tax under the portfolio interest exemption) or any successor form; or

(D) any other applicable form, certificate or document prescribed by the IRS certifying as to such Non-U.S. Lender’s entitlement to such exemption from U.S. withholding tax or reduced rate with respect to all payments to be made to such Non-U.S. Lender under the Loan Documents.

Unless the Borrower and the Administrative Agent have received forms or other documents satisfactory to them indicating that payments under any Loan Document to or for a Non-U.S. Lender are not subject to U.S. withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty, (i) the Loan Parties and the Administrative Agent shall withhold amounts required to be withheld by applicable Requirements of Law from such payments at the applicable statutory rate and (ii) the Borrower shall have no obligation to gross up for such deductions as provided in Section 2.16(a) (Taxes) to the extent such withholding arises by reason of such failure.

(ii) Each U.S. Lender shall (v) on or prior to the Closing Date in the case of each U.S. Lender that is a signatory hereto, (w) on or prior to the date of the Assignment and Acceptance pursuant to which such U.S. Lender becomes a Lender, on or prior to the date a successor Issuer becomes an Issuer or on or prior to the date a successor Administrative Agent becomes the Administrative Agent hereunder, (x) on or prior to the date on which any such form or certification expires or becomes obsolete, (y) after the occurrence of any event requiring a change in the most recent form or certification previously delivered by it to the Borrower and the Administrative Agent, and (z) from time to time if requested by the Borrower or the Administrative Agent, provide the Administrative Agent and the Borrower with two completed originals of Form W-9 (certifying that such U.S. Lender is entitled to an exemption from U.S. backup withholding tax) or any successor form.

Credit Agreement
Orbital Sciences Corporation

Unless the Borrower and the Administrative Agent have received forms or other documents satisfactory to them indicating that payments under any Loan Document to or for a U.S. Lender are not subject to U.S. backup withholding tax, the Loan Parties and the Administrative Agent shall withhold amounts required to be withheld by applicable Requirements of Law from such payments at the applicable statutory rate and, to the extent such Lenders were able to deliver such forms, without the requirement for the Borrower to gross up for such deductions as provided in Section 2.16(a) (Taxes) by reason of such failure.

(g) Any Lender claiming any additional amounts payable pursuant to this Section 2.16 shall use its reasonable efforts (consistent with its internal policies and Requirements of Law) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that would be payable or may thereafter accrue and would not, in the sole determination of such Lender, be otherwise disadvantageous to such Lender.

Section 2.17 Substitution of Lenders

(a) In the event that (i)(A) any Lender makes a claim under Section 2.14(c) (Increased Costs) or Section 2.15 (Capital Adequacy), (B) it becomes illegal for any Lender to continue to fund or make any Eurodollar Rate Loan and such Lender notifies the Borrower pursuant to Section 2.14(d) (Illegality), (C) any Loan Party is required to make any payment pursuant to Section 2.16 (Taxes) that is attributable to a particular Lender or (D) any Lender becomes a Non-Funding Lender, (ii) in the case of clause (i)(A) above, as a consequence of increased costs in respect of which such claim is made, the effective rate of interest payable to such Lender under this Agreement with respect to its Loans exceeds the effective average annual rate of interest payable to the Requisite Lenders under this Agreement and (iii) in the case of clause (i)(A),(B) and (C) above, Lenders holding at least 75% of the Commitments are not subject to such increased costs or illegality, payment or proceedings (any such Lender, an “Affected Lender”), the Borrower may substitute any Lender and, if reasonably acceptable to the Administrative Agent, any other Eligible Assignee (a “Substitute Institution”) for such Affected Lender hereunder, after delivery of a written notice (a “Substitution Notice”) by the Borrower to the Administrative Agent and the Affected Lender within a reasonable time (in any case not to exceed 90 days) following the occurrence of any of the events described in clause (i) above that the Borrower intends to make such substitution; provided, however, that, if more than one Lender claims increased costs, illegality or right to payment arising from the same act or condition and such claims are received by the Borrower within 30 days of each other, then the Borrower may substitute all, but not (except to the extent the Borrower has already substituted one of such Affected Lenders before the Borrower’s receipt of the other Affected Lenders’ claim) less than all, Lenders making such claims.

(b) If the Substitution Notice was properly issued under this Section 2.17, the Affected Lender shall sell, and the Substitute Institution shall purchase, all rights and claims of such Affected Lender under the Loan Documents and the Substitute Institution shall assume, and the Affected Lender shall be relieved of, the Affected Lender’s Commitments and all other prior unperformed obligations of the Affected Lender under the Loan Documents (other than in respect of any damages (which pursuant to Section 11.5, do not include exemplary or punitive damages, to the extent permitted by applicable law) in respect of any such unperformed obligations). Such purchase and sale (and the corresponding assignment of all rights and claims hereunder) shall be recorded in the Register maintained by the Administrative Agent and shall be

effective on (and not earlier than) the later of (i) the receipt by the Affected Lender of its Ratable Portion of the Revolving Credit Outstandings, together with any other Obligations owing to it, (ii) the receipt by the Administrative Agent of an agreement in form and substance satisfactory to it and the Borrower whereby the Substitute Institution shall agree to be bound by the terms hereof and (ii) the payment in full to the Affected Lender in cash of all fees, unreimbursed costs and expenses and indemnities accrued and unpaid through such effective date. Upon the effectiveness of such sale, purchase and assumption, the Substitute Institution shall become a “Lender” hereunder for all purposes of this Agreement having a Commitment in the amount of such Affected Lender’s Commitment assumed by it and such Commitment of the Affected Lender shall be terminated; provided, however, that all indemnities under the Loan Documents shall continue in favor of such Affected Lender.

(c) Each Lender agrees that, if it becomes an Affected Lender and its rights and claims are assigned hereunder to a Substitute Institution pursuant to this Section 2.17, it shall execute and deliver to the Administrative Agent an Assignment and Acceptance to evidence such assignment, together with any Note (if such Loans are evidenced by a Note) evidencing the Loans subject to such Assignment and Acceptance; provided, however, that the failure of any Affected Lender to execute an Assignment and Acceptance shall not render such assignment invalid.

(c) The Administrative Agent shall maintain at its address referred to in Section 11.8 (Notices, Etc.) a copy of each Assignment and Acceptance delivered to and accepted by it and shall record in the Register the names and addresses of the Lenders and Issuers and the principal amount of the Loans and Reimbursement Obligations owing to each Lender from time to time and the Commitments of each Lender. Any assignment pursuant to this Section 11.2 shall not be effective until such assignment is recorded in the Register.

(d) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee, the Administrative Agent shall, if such Assignment and Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii) record or cause to be recorded the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower. Within five Business Days after its receipt of such notice, the Borrower, at its own expense, shall, if requested by such assignee, execute and deliver to the Administrative Agent new Notes to the order of such assignee in an amount equal to the Commitments and Loans assumed by it pursuant to such Assignment and Acceptance and, if the assigning Lender has surrendered any Note for exchange in connection with the assignment and has retained Commitments or Loans hereunder, new Notes to the order of the assigning Lender in an amount equal to the Commitments and Loans retained by it hereunder. Such new Notes shall be dated the same date as the surrendered Notes and be in substantially the form of Exhibit B (Form of Note).

(e) In addition to the other assignment rights provided in this Section 11.2, each Lender may do each of the following:

(i) grant to a Special Purpose Vehicle the option to make all or any part of any Loan that such Lender would otherwise be required to make hereunder and the exercise of such option by any such Special Purpose Vehicle and the making of Loans pursuant thereto shall satisfy (once and to the extent that such Loans are made) the obligation of such Lender to make such Loans thereunder; provided, however, that (x) nothing herein shall constitute a commitment or an offer to commit by such a Special Purpose Vehicle to make Loans hereunder and no such Special Purpose Vehicle shall be liable for any indemnity or other Obligation (other than the making of Loans for which such Special Purpose Vehicle shall have exercised an option, and then only in accordance with the relevant option agreement) and (y) such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain responsible to the other

Credit Agreement
Orbital Sciences Corporation

parties for the performance of its obligations under the terms of this Agreement and shall remain the holder of the Obligations for all purposes hereunder; and

(ii) assign, as collateral or otherwise, any of its rights under this Agreement, whether now owned or hereafter acquired (including rights to payments of principal or interest on the Loans), to (A) without notice to or consent of the Administrative Agent or the Borrower, any Federal Reserve Bank (pursuant to Regulation A of the Federal Reserve Board) and (B) without consent of the Administrative Agent or the Borrower, (1) any holder of, or trustee for the benefit of, the holders of such Revolving Credit Lender’s Securities and (2) any Special Purpose Vehicle to which such Revolving Credit Lender has granted an option pursuant to clause (i) above;

provided, however, that no such assignment or grant shall release such Revolving Credit Lender from any of its obligations hereunder except as expressly provided in clause (i) above and except, in the case of a subsequent foreclosure pursuant to an assignment as collateral, if such foreclosure is made in compliance with the other provisions of this Section 11.2 other than this clause (e) or clause (f) below. Each party hereto acknowledges and agrees that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior debt of any such Special Purpose Vehicle, such party shall not institute against, or join any other Person in instituting against, any Special Purpose Vehicle that has been granted an option pursuant to this clause (e) any bankruptcy, reorganization, insolvency or liquidation proceeding (such agreement shall survive the payment in full of the Obligations). The terms of the designation of, or assignment to, such Special Purpose Vehicle shall not restrict such Lender’s ability to, or grant such Special Purpose Vehicle the right to, consent to any amendment or waiver to this Agreement or any other Loan Document or to the departure by the Borrower from any provision of this Agreement or any other Loan Document without the consent of such Special Purpose Vehicle except, as long as the Administrative Agent and the Lenders, Issuers and other Secured Parties shall continue to, and shall be entitled to continue to, deal solely and directly with such Lender in connection with such Lender’s obligations under this Agreement, to the extent any such consent would reduce the principal amount of, or the rate of interest on, any Obligations, amend this clause (e) or postpone any scheduled date of payment of such principal or interest. Each Special Purpose Vehicle shall be entitled to the benefits of Sections 2.15 (Capital Adequacy) and 2.16 (Taxes) and of 2.14(d) (Illegality) as if it were such Lender; provided, however, that anything herein to the contrary notwithstanding, no Borrower shall, at any time, be obligated to make under Section 2.15 (Capital Adequacy), 2.16 (Taxes) or 2.14(d) (Illegality) to any such Special Purpose Vehicle and any such Lender any payment in excess of the amount the Borrower would have been obligated to pay to such Lender in respect of such interest if such Special Purpose Vehicle had not been assigned the rights of such Lender hereunder; and provided, further, that such Special Purpose Vehicle shall have no direct right to enforce any of the terms of this Agreement against the Borrower, the Administrative Agent or the other Lenders.

(f) Each Lender may sell participations to one or more Persons in or to all or a portion of its rights and obligations under the Loan Documents (including all its rights and obligations with respect to the Revolving Loans and Letters of Credit). The terms of such participation shall not, in any event, require the participant’s consent to any amendments, waivers or other modifications of any provision of any Loan Documents, the consent to any departure by any Loan Party therefrom, or to the exercising or refraining from exercising any powers or rights such Lender may have under or in respect of the Loan Documents (including the right to enforce

Credit Agreement
Orbital Sciences Corporation

the obligations of the Loan Parties), except if any such amendment, waiver or other modification or consent would (i) reduce the amount, or postpone any date fixed for, any amount (whether of principal, interest or fees) payable to such participant under the Loan Documents, to which such participant would otherwise be entitled under such participation or (ii) result in the release of all or substantially all of the Collateral other than in accordance with Section 10.8(b) (Concerning the Collateral and the Collateral Documents). In the event of the sale of any participation by any Lender, (w) such Lender’s obligations under the Loan Documents shall remain unchanged, (x) such Lender shall remain solely responsible to the other parties for the performance of such obligations, (y) such Lender shall remain the holder of such Obligations for all purposes of this Agreement and (z) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Each participant shall be entitled to the benefits of Sections 2.15 (Capital Adequacy) and 2.16 (Taxes) and of 2.14(d) (Illegality) as if it were a Lender; provided, however, that anything herein to the contrary notwithstanding, the Borrower shall not, at any time, be obligated to make under Section 2.15 (Capital Adequacy), 2.16 (Taxes) or 2.14(d) (Illegality) to the participants in the rights and obligations of any Lender (together with such Lender) any payment in excess of the amount the Borrower would have been obligated to pay to such Lender in respect of such interest had such participation not been sold and provided, further, that such participant in the rights and obligations of such Lender shall have no direct right to enforce any of the terms of this Agreement against the Borrower, the Administrative Agent or the other Lenders.

(g) Any Issuer may at any time assign its rights and obligations hereunder to any other Lender by an instrument in form and substance satisfactory to the Borrower, the Administrative Agent, such Issuer and such Lender, subject to the provisions of Section 2.7(b) (Evidence of Debt) relating to notations of transfer in the Register. If any Issuer ceases to be a Lender hereunder by virtue of any assignment made pursuant to this Section 11.2, then, as of the effective date of such cessation, such Issuer’s obligations to Issue Letters of Credit pursuant to Section 2.4 (Letters of Credit) shall terminate and such Issuer shall be an Issuer hereunder only with respect to outstanding Letters of Credit issued prior to such date.

Credit Agreement

any kind or nature (including fees, disbursements and expenses of financial and legal advisors to any such Indemnitee) that may be imposed on, incurred by or asserted against any such Indemnitee in connection with or arising out of any investigation, litigation or proceeding, whether or not such investigation, litigation or proceeding is brought by any such indemnitee or any of its directors, security holders or creditors or any such Indemnitee, director, security holder or creditor is a party thereto, whether direct, indirect, or consequential and whether based on any federal, state or local law or other statutory regulation, securities or commercial law or regulation, or under common law or in equity, or on contract, tort or otherwise, in any manner relating to or arising out of this Agreement, any other Loan Document, any Obligation or any Letter of Credit, or any act, event or transaction related or attendant to any thereof, or the use or intended use of the proceeds of the Loans or Letters of Credit or in connection with any investigation of any potential matter covered hereby (collectively, the “Indemnified Matters”); provided, however, that the Borrower shall not have any liability under this Section 11.4 to an Indemnitee with respect to any Indemnified Matter to the extent resulting from the gross negligence or willful misconduct of that Indemnitee, as determined by a court of competent jurisdiction in a final non-appealable judgment or order. Without limiting the foregoing, “Indemnified Matters” include (i) all Environmental Liabilities and Costs arising from or connected with the past, present or future operations of the Borrower or any of its Subsidiaries involving any property subject to a Collateral Document, or damage to real or personal property or natural resources or harm or injury alleged to have resulted from any Release of Contaminants on, upon or into such property or any contiguous real estate, (ii) any costs or liabilities incurred in connection with any environmental remedial action concerning the Borrower or any of its Subsidiaries, (iii) any costs or liabilities incurred in connection with any Environmental Lien and (iv) any costs or liabilities incurred in connection with any other matter under any Environmental Law, including the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (49 U.S.C. § 9601 et seq.) and applicable state property transfer laws, whether, with respect to any such matter, such Indemnitee is a mortgagee pursuant to any leasehold mortgage, a mortgagee in possession, the successor in interest to the Borrower or any of its Subsidiaries, or the owner, lessee or operator of any property of the Borrower or any of its Subsidiaries by virtue of foreclosure, except, with respect to those matters referred to in clauses (i), (ii), (iii) and (iv) above, to the extent (x) incurred following foreclosure by the Administrative Agent, any Lender or any Issuer, or the Administrative Agent, any Lender or any Issuer having become the successor in interest to the Borrower or any of its Subsidiaries and (y) attributable solely to acts of the Administrative Agent, such Lender or such Issuer or any agent on behalf of the Administrative Agent, such Lender or such Issuer.

(b) The Borrower shall indemnify the Administrative Agent, the Lenders and each Issuer for, and hold the Administrative Agent, the Lenders and each Issuer harmless from and against, any and all claims for brokerage commissions, fees and other compensation made against the Administrative Agent, the Lenders and the Issuers for any broker, finder or consultant with respect to any agreement, arrangement or understanding made by or on behalf of any Loan Party or any of its Subsidiaries (other than pursuant to a contractual arrangement to which the Person seeking such indemnification is a party) in connection with the transactions contemplated by this Agreement.

(c) Promptly after receipt by an Indemnitee of notice of the commencement of any action or proceeding involving a claim referred to in subsection (a) or (b) above, such Indemnitee shall promptly give notice to the Borrower of the commencement of such action or proceeding; provided, however, that the failure of such Indemnitee to give notice provided in this

Credit Agreement
Orbital Sciences Corporation

subsection (c) shall not (i) relieve the Borrower of its Obligations under this Section 11.4, except to the extent that the Borrower has been materially prejudiced by such failure, and (ii) in any event relieve Borrower from any liability with respect to such Indemnitee which the Borrower may have otherwise on account of this Agreement. If any such action or proceeding is brought against any Indemnitee, unless in the reasonable opinion of counsel for such Indemnitee a conflict of interest between such Indemnitee and the Borrower may exist in respect of such action or proceeding and representation of both would be inappropriate, the Borrower shall be entitled to participate in and to assume the defense thereof with counsel reasonably satisfactory to such Indemnitee, and after notice from the Borrower to such Indemnitee of its election so to assume the defense thereof, (x) the Borrower shall not be liable to such Indemnitee for any legal or other expenses subsequently incurred by such Indemnitee in connection with the defense thereof and (y) such Indemnitee shall take all action that the Borrower may reasonably request (and that is reasonably necessary or appropriate and would not, in the reasonable judgment of such Indemnitee, be materially disadvantageous to such Indemnitee) in order to cooperate in the Borrower’s participation in and assumption of such defense. The Borrower shall not be liable for any settlement of any action or claim effected without the Borrower’s consent (which consent shall not be unreasonably withheld), and the Borrower shall not settle or compromise any action or claim affecting any Indemnitee without such Indemnitee’s prior written consent (which shall not be unreasonably withheld) if the settlement or compromise involves any performance by, or adverse admission of, such Indemnitee.

(d) The Borrower agrees that any indemnification or other protection provided to any Indemnitee pursuant to this Agreement (including pursuant to this Section 11.4) or any other Loan Document (unless otherwise provided therein) shall (i) survive payment in full of the Obligations and (ii) inure to the benefit of any Person that was at any time an Indemnitee under this Agreement or any other Loan Document.

Section 11.5 Limitation of Liability

(a) The Borrower agrees that no Indemnitee shall have any liability (whether in contract, tort or otherwise) to any Loan Party or any of their respective Subsidiaries or any of their respective equity holders or creditors for or in connection with the transactions contemplated hereby and in the other Loan Documents, except to the extent such liability is determined in a final non-appealable judgment by a court of competent jurisdiction to have resulted primarily from such Indemnitee’s gross negligence or willful misconduct. In no event, however, shall any Indemnitee be liable on any theory of liability for any special, indirect, consequential or punitive damages (including, without limitation, any loss of profits, business or anticipated savings). The Borrower hereby waives, releases and agrees (each for itself and on behalf of its Subsidiaries) not to sue upon any such claim for any special, indirect, consequential or punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor.

(b) IN NO EVENT SHALL ANY AGENT AFFILIATE HAVE ANY LIABILITY TO ANY LOAN PARTY, LENDER, ISSUER OR ANY OTHER PERSON FOR DAMAGES OF ANY KIND, INCLUDING DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT OR CONTRACT OR OTHERWISE) ARISING OUT OF ANY LOAN PARTY OR ANY AGENT AFFILIATE’S TRANSMISSION OF APPROVED ELECTRONIC COMMUNICATIONS THROUGH THE INTERNET OR ANY USE OF THE APPROVED ELECTRONIC PLATFORM, EXCEPT TO THE EXTENT SUCH LIABILITY OF ANY AGENT AFFILIATE IS FOUND IN A FINAL NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT

Upon the occurrence and during the continuance of any Event of Default each Lender and each Affiliate of a Lender is hereby authorized, with the consent of the Administrative Agent (which consent shall not be required following the acceleration of the Obligations pursuant to Section 9.2 (Remedies)), at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Indebtedness at any time owing by such Lender or its Affiliates to or for the credit or the account of the Borrower against any and all of the Obligations now or hereafter existing whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and even though such Obligations may be unmatured. Each Lender agrees promptly to notify the Borrower after any such set-off and application made by such Lender or its Affiliates; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section 11.6 are in addition to the other rights and remedies (including other rights of set-off) that such Lender may have.

Section 11.7 Sharing of Payments, Etc.

(b) If all or any portion of any payment received by a Purchasing Lender is thereafter recovered from such Purchasing Lender, such purchase from each Selling Lender shall be rescinded and such Selling Lender shall repay to the Purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Selling Lender’s ratable share (according to the proportion of (i) the amount of such Selling Lender’s required repayment in relation to (ii) the total amount so recovered from the Purchasing Lender) of any interest or other amount paid or payable by the Purchasing Lender in respect of the total amount so recovered.

(c) The Borrower agrees that any Purchasing Lender so purchasing a participation from a Selling Lender pursuant to this Section 11.7 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to

Guaranty

Guaranty, dated as of ___, ___(this “Guaranty”), by [Name of Guarantor(s)] (“Guarantors”), in favor of the Administrative Agent, each Lender, each Issuer and each other holder of an Obligation (as each such term is defined in the Credit Agreement referred to below) (each, a “Guarantied Party” and, collectively, the “Guarantied Parties”).

Witnesseth:

Whereas, pursuant to the Credit Agreement dated as of August 17, 2007 (together with all appendices, exhibits and schedules thereto and as the same may be amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; capitalized terms defined therein and used herein having the meanings given to them in the Credit Agreement) among Orbital Sciences Corporation (the “Borrower”), the Lenders and Issuers party thereto and Citibank, N.A. as agent for the Lenders and Issuers (in such capacity, the “Administrative Agent”), the Lenders and Issuers have severally agreed to make extensions of credit to the Borrower upon the terms and subject to the conditions set forth therein; and

Whereas, each Guarantor will receive substantial direct and indirect benefits from the making of the Loans, the issuance of the Letters of Credit and the granting of the other financial accommodations to the Borrower under the Credit Agreement;

Now, Therefore, in consideration of the premises set forth above, the terms and conditions contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

Section 1 Guaranty

(a) To induce the Lenders to make the Loans and the Issuers to issue Letters of Credit, each Guarantor hereby absolutely, unconditionally and irrevocably guarantees, jointly with the other Guarantors and severally, as primary obligor and not merely as surety, the full and punctual payment when due and in the currency due, whether at stated maturity or earlier, by reason of acceleration, mandatory prepayment or otherwise in accordance herewith or any other Loan Document, of all the Obligations, whether or not from time to time reduced or extinguished or hereafter increased or incurred, whether or not recovery may be or hereafter may become barred by any statute of limitations, whether or not enforceable as against the Borrower, whether now or hereafter existing, and whether due or to become due, including principal, interest (including interest at the contract rate applicable upon default accrued or accruing after the commencement of any proceeding under the Bankruptcy Code, or any applicable provisions of comparable state or foreign law, whether or not such interest is an allowed claim in such proceeding), fees and costs of collection. This Guaranty constitutes a guaranty of payment and not of collection.

(b) Each Guarantor further agrees that, if (i) any payment made by Borrower or any 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 (ii) the proceeds of Collateral are required to be returned by any Guarantied Party to the Borrower, its estate, trustee, receiver or any other party, including any Guarantor, under any bankruptcy law, equitable cause or any other Requirement of Law, then, to the extent of such payment or repayment, any such Guarantor’s liability hereunder (and any Lien or other

Guaranty
Orbital Sciences Corporation

Collateral securing such liability) shall be and remain in full force and effect, as fully as if such payment had never been made. If, prior to any of the foregoing, this Guaranty shall have been cancelled or surrendered (and if any Lien or other Collateral securing such Guarantor’s liability hereunder shall have been released or terminated by virtue of such cancellation or surrender), this Guaranty (and 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 the obligations of any such Guarantor in respect of the amount of such payment (or any Lien or other Collateral securing such obligation).

Section 2 Limitation of Guaranty

Any term or provision of this Guaranty or any other Loan Document to the contrary notwithstanding, the maximum aggregate amount of the Obligations for which any Guarantor shall be liable shall not exceed the maximum amount for which such Guarantor can be liable without rendering this Guaranty or any other Loan Document, as it relates to such Guarantor, subject to avoidance under applicable law relating to fraudulent conveyance or fraudulent transfer (including Section 548 of the Bankruptcy Code or any applicable provisions of comparable state law) (collectively, "Fraudulent Transfer Laws”), in each case after giving effect (a) to all other liabilities of such Guarantor, contingent or otherwise, that are relevant under such Fraudulent Transfer Laws (specifically excluding, however, any liabilities of such Guarantor in respect of intercompany Indebtedness to the Borrower to the extent that such Indebtedness would be discharged in an amount equal to the amount paid by such Guarantor hereunder) and (b) to the value as assets of such Guarantor (as determined under the applicable provisions of such Fraudulent Transfer Laws) of any rights to subrogation, contribution, reimbursement, indemnity or similar rights held by such Guarantor pursuant to (i) applicable Requirements of Law, (ii) Section 3 (Contribution) of this Guaranty or (iii) any other Contractual Obligations providing for an equitable allocation among such Guarantor and other Subsidiaries or Affiliates of the Borrower of obligations arising under this Guaranty or other guaranties of the Obligations by such parties.

Section 3 Contribution

To the extent that any Guarantor shall be required hereunder to pay a portion of the Obligations exceeding the greater of (a) the amount of the economic benefit actually received by such Guarantor from the Revolving Loans and the other financial accommodations provided to the Borrower under the Loan Documents and (b) the amount such Guarantor would otherwise have paid if such Guarantor had paid the aggregate amount of the Obligations (excluding the amount thereof repaid by the Borrower) in the same proportion as such Guarantor’s net worth at the date enforcement is sought hereunder bears to the aggregate net worth of all the Guarantors at the date enforcement is sought hereunder, then such Guarantor shall be reimbursed by such other Guarantors for the amount of such excess, pro rata, based on the respective net worths of such other Guarantors at the date enforcement hereunder is sought.

Section 4 Authorization; Other Agreements

The Guarantied Parties are hereby authorized, without notice to, or demand upon, any Guarantor, which notice and demand requirements each are expressly waived hereby, and without discharging or otherwise affecting the obligations of such Guarantor hereunder (which obligations shall remain absolute and unconditional notwithstanding any such action or omission

Guaranty
Orbital Sciences Corporation

to act), from time to time, to do each of the following to the extent permitted by the applicable Requirement of Law:

(a) supplement, renew, extend, accelerate or otherwise change the time for payment of, or other terms relating to, the Obligations, or any part of them, or otherwise modify, amend or change the terms of any promissory note or other agreement, document or instrument (including the other Loan Documents) now or hereafter executed by the Borrower and delivered to the Guarantied Parties or any of them, including any increase or decrease of principal or the rate of interest thereon;

(b) waive or otherwise consent to noncompliance with any provision of any instrument evidencing the Obligations, or any part thereof, or any other instrument or agreement in respect of the Obligations (including the other Loan Documents) now or hereafter executed by the Borrower and delivered to the Guarantied Parties or any of them;

(d) receive, take and hold additional security or collateral for the payment of the Obligations or any part of them and exchange, enforce, waive, substitute, liquidate, terminate, abandon, fail to perfect, subordinate, transfer, otherwise alter and release any such additional security or collateral;

(g) apply to the Obligations any payment or recovery (x) from the Borrower, from any other guarantor, maker or endorser of the Obligations or any part of them or (y) from any Guarantor in such order as provided herein, in each case whether such Obligations are secured or unsecured or guaranteed or not guaranteed by others;

(h) apply to the Obligations any payment or recovery from any Guarantor of the Obligations or any sum realized from security furnished by such Guarantor upon its indebtedness or obligations to the Guarantied Parties or any of them, in each case whether or not such indebtedness or obligations relate to the Obligations; and

(i) refund at any time any payment received by any Guarantied Party in respect of any Obligation, and payment to such Guarantied Party of the amount so refunded shall be fully guaranteed hereby even though prior thereto this Guaranty shall have been cancelled or surrendered (or any release or termination of any Collateral by virtue thereof), and such prior cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect the obligations of any Guarantor hereunder in respect of the amount so refunded (and any Collateral so released or terminated shall be reinstated with respect to such obligations);

even if any right of reimbursement or subrogation or other right or remedy of any Guarantor is extinguished, affected or impaired by any of the foregoing (including any election of remedies by

Guaranty
Orbital Sciences Corporation

reason of any judicial, non-judicial or other proceeding in respect of the Obligations that impairs any subrogation, reimbursement or other right of such Guarantor).

Section 5 Guaranty Absolute and Unconditional

Each Guarantor hereby waives any defense of a surety or guarantor or any other obligor on any obligations arising in connection with or in respect of any of the following and hereby agrees that its obligations under this Guaranty are absolute and unconditional and shall not be discharged or otherwise affected as a result of any of the following:

(a) the invalidity or unenforceability of any of the Borrower’s obligations under the Credit Agreement or any other Loan Document or any other agreement or instrument relating thereto, or any security for, or other guaranty of the Obligations or any part of them, or the lack of perfection or continuing perfection or failure of priority of any security for the Obligations or any part of them;

(e) any borrowing or grant of a Lien by the Borrower, as debtor-in-possession, or extension of credit, under Section 364 of the Bankruptcy Code or any applicable provisions of comparable state or foreign law;

(f) the disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of any Guarantied Party’s claim (or claims) for repayment of the Obligations ;

(g) any use of cash collateral under Section 363 of the Bankruptcy Code;

(h) any agreement or stipulation as to the provision of adequate protection in any bankruptcy proceeding;

(m) any election following the occurrence of an Event of Default by any Guarantied Party to proceed separately against the personal property Collateral in accordance with such Guarantied Party’s rights under the UCC or, if the Collateral consists of both personal and real property, to proceed against such personal and real property in accordance with such Guarantied Party’s rights with respect to such real property;

(n) any change in the corporate existence or structure of the Borrower or any other Loan Party;

(o) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by any Guarantor or any other Person against any Guarantied Party;

(p) any Requirement of Law affecting any term of any Guarantor’s obligations under this Guaranty; or

(q) any other circumstance that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor or any other obligor on any obligations, other than the payment in full of the Obligations.

Section 6 Waivers

Each Guarantor hereby waives diligence, promptness, presentment, demand for payment or performance and protest and notice of protest, notice of acceptance and any other notice in respect of the Obligations or any part of them, and any defense arising by reason of any disability or other defense of the Borrower. Each Guarantor shall not, until the Obligations are irrevocably paid in full and the Commitments have been terminated, assert any claim or counterclaim it may have against the Borrower or set off any of its obligations to the Borrower against any obligations of the Borrower to it. In connection with the foregoing, each Guarantor covenants that its obligations hereunder shall not be discharged, except by complete performance.

Section 7 Reliance

Each Guarantor hereby assumes responsibility for keeping itself informed of the financial condition of the Borrower and any endorser and other guarantor of all or any part of the Obligations, and of all other circumstances bearing upon the risk of nonpayment of the Obligations, or any part thereof, that diligent inquiry would reveal, and each Guarantor hereby agrees that no Guarantied Party shall have any duty to advise any Guarantor of information known to it regarding such condition or any such circumstances. In the event any Guarantied Party, in its sole discretion, undertakes at any time or from time to time to provide any such information to any Guarantor, such Guarantied Party shall be under no obligation (a) to undertake any investigation not a part of its regular business routine, (b) to disclose any information that such Guarantied Party, pursuant to accepted or reasonable commercial finance or banking practices, wishes to maintain confidential or (c) to make any other or future disclosures of such information or any other information to any Guarantor.

Guaranty
Orbital Sciences Corporation

Section 8 Waiver of Subrogation and Contribution Rights

Until the Obligations have been irrevocably paid in full and the Commitments have been terminated, the Guarantors shall not enforce or otherwise exercise any right of subrogation to any of the rights of the Guarantied Parties or any part of them against the Borrower or any right of reimbursement or contribution or similar right against the Borrower by reason of this Guaranty or by any payment made by any Guarantor in respect of the Obligations.

Section 9 Subordination

Each Guarantor hereby agrees that any Indebtedness of the Borrower now or hereafter owing to any Guarantor, whether heretofore, now or hereafter created (the “Guarantor Subordinated Debt”), is hereby subordinated to all of the Obligations and that, except as permitted under Section 8.6 (Restricted Payments) of the Credit Agreement, the Guarantor Subordinated Debt shall not be paid in whole or in part until the Obligations have been paid in full and this Guaranty is terminated and of no further force or effect. No Guarantor shall accept any payment of or on account of any Guarantor Subordinated Debt at any time in contravention of the foregoing. Upon the occurrence and during the continuance of an Event of Default, the Guarantor shall cause Borrower to pay to the Administrative Agent any payment of all or any part of the Guarantor Subordinated Debt and any amount so paid to the Administrative Agent shall be applied to payment of the Obligations as provided in Section 2.13(f) (Payments and Computations) of the Credit Agreement. Each payment on the Guarantor Subordinated Debt received in violation of any of the provisions hereof shall be deemed to have been received by such Guarantor as trustee for the Guarantied Parties and shall be paid over to the Administrative Agent immediately on account of the Obligations, but without otherwise affecting in any manner such Guarantor’s liability hereof. Each Guarantor agrees to file all claims against the Borrower in any bankruptcy or other proceeding in which the filing of claims is required by law in respect of any Guarantor Subordinated Debt, and the Administrative Agent shall be entitled to all of such Guarantor’s rights thereunder. If for any reason a Guarantor fails to file such claim at least ten Business Days prior to the last date on which such claim should be filed, such Guarantor hereby irrevocably appoints the Administrative Agent as its true and lawful attorney-in-fact and is hereby authorized to act as attorney-in-fact in such Guarantor’s name to file such claim or, in the Administrative Agent’s discretion, to assign such claim to and cause proof of claim to be filed in the name of the Administrative Agent or its nominee. In all such cases, whether in administration, bankruptcy or otherwise, the person or persons authorized to pay such claim shall pay to the Administrative Agent the full amount payable on the claim in the proceeding, and, to the full extent necessary for that purpose, each Guarantor hereby assigns to the Administrative Agent all of such Guarantor’s rights to any payments or distributions to which such Guarantor otherwise would be entitled. If the amount so paid is greater than such Guarantor’s liability hereunder, the Administrative Agent shall pay the excess amount to the party entitled thereto. In addition, each Guarantor hereby irrevocably appoints the Administrative Agent as its attorney-in-fact to exercise all of such Guarantor’s voting rights in connection with any bankruptcy proceeding or any plan for the reorganization of the Borrower.

Section 10 Default; Remedies

The obligations of each Guarantor hereunder are independent of and separate from the Obligations. If any Obligation is not paid when due, or upon any Event of Default hereunder or upon any Event of Default by the Borrower as provided in any other instrument or document evidencing all or any part of the Obligations, the Administrative Agent may, at its sole

Guaranty
Orbital Sciences Corporation

election, proceed directly and at once, without notice, against any Guarantor to collect and recover the full amount or any portion of the Obligations then due, without first proceeding against the Borrower or any other guarantor of the Obligations, or against any Collateral under the Loan Documents or joining the Borrower or any other guarantor in any proceeding against any Guarantor. At any time after maturity of the Obligations, the Administrative Agent may (unless the Obligations have been irrevocably paid in full), without notice to any Guarantor and regardless of the acceptance of any Collateral for the payment hereof, appropriate and apply toward the payment of the Obligations (a) any indebtedness due or to become due from any Guarantied Party to such Guarantor and (b) any moneys, credits or other property belonging to such Guarantor at any time held by or coming into the possession of any Guarantied Party or any of its respective Affiliates.

Section 11 Irrevocability

This Guaranty shall be irrevocable as to the Obligations (or any part thereof) until the Commitments have been terminated and all monetary Obligations then outstanding have been irrevocably repaid in cash, at which time this Guaranty shall automatically be cancelled. Upon such cancellation and at the written request of any Guarantor or its successors or assigns, and at the cost and expense of such Guarantor or its successors or assigns, the Administrative Agent shall execute in a timely manner a satisfaction of this Guaranty and such instruments, documents or agreements as are necessary or desirable to evidence the termination of this Guaranty.

Section 12 Setoff

Upon the occurrence and during the continuance of an Event of Default, each Guarantied Party and each Affiliate of a Guarantied Party may, with the consent of the Administrative Agent (which consent shall not be required following the acceleration of the Obligations pursuant to Section 9.2 (Remedies) of the Credit Agreement), appropriate and apply toward the payment of all or any part of the Obligations, regardless of the acceptance of any security or collateral for the payment hereof, (a) any Indebtedness due or to become due from such Guarantied Party or Affiliate to such Guarantor and (b) any and all deposits (general or special, time or demand, provisional or final) at any time held by such Guarantied Party or Affiliate. Each Guarantied Party agrees promptly to notify such Guarantor after any such set-off and application made by such Guarantied Party or its Affiliates; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.

Section 13 No Marshalling

Each Guarantor consents and agrees that no Guarantied Party or Person acting for or on behalf of any Guarantied Party shall be under any obligation to marshal any assets in favor of any Guarantor or against or in payment of any or all of the Obligations.

Section 14 Enforcement; Waivers; Amendments

(a) No delay on the part of any Guarantied Party in the exercise of any right or remedy arising under this Guaranty, the Credit Agreement, any other Loan Document or otherwise with respect to all or any part of the Obligations, the Collateral or any other guaranty of or security for all or any part of the Obligations shall operate as a waiver thereof, and no single or partial exercise by any such Person of any such right or remedy shall preclude any further

Guaranty
Orbital Sciences Corporation

exercise thereof. Failure by any Guarantied Party at any time or times hereafter to require strict performance by the Borrower, any Guarantor, any other guarantor of all or any part of the Obligations or any other Person of any provision, warranty, term or condition contained in any Loan Document now or at any time hereafter executed by any such Persons and delivered to any Guarantied Party shall not waive, affect or diminish any right of any Guarantied Party at any time or times hereafter to demand strict performance thereof and such right shall not be deemed to have been waived by any act (except by a written instrument pursuant to Section 14(b) or knowledge of any Guarantied Party, or its respective agents, officers or employees. No waiver of any Event of Default by any Guarantied Party shall operate as a waiver of any other Event of Default or the same Event of Default on a future occasion, and no action by any Guarantied Party permitted hereunder shall in any way affect or impair any Guarantied Party’s rights and remedies or the obligations of any Guarantor under this Guaranty. Any determination by a court of competent jurisdiction of the amount of any principal or interest owing by the Borrower to a Guarantied Party shall be conclusive and binding on each Guarantor irrespective of whether such Guarantor was a party to the suit or action in which such determination was made.

(b) None of the terms or provisions of this Guaranty may be waived, amended, supplemented or modified except in accordance with Section11.1 (Amendments, Waivers, Etc.) of the Credit Agreement.

Section 15 Successors and Assigns

This Guaranty shall be binding upon each Guarantor and upon the successors and assigns of such Guarantors and shall inure to the benefit of the Guarantied Parties and their respective successors and assigns; all references herein to the Borrower and to the Guarantors shall be deemed to include their respective successors and assigns. The successors and assigns of the Guarantors and the Borrower shall include, without limitation, their respective receivers, trustees and debtors-in-possession. All references to the singular shall be deemed to include the plural where the context so requires.

Section 16 Representations and Warranties; Covenants

Each Guarantor hereby (a) represents and warrants that the representations and warranties as to it made by the Borrower in Article IV (Representations and Warranties) of the Credit Agreement are true and correct on each date as required by Section 3.2(b)(i) (Conditions Precedent to Each Loan and Letter of Credit) of the Credit Agreement and (b) agrees, to the extent permitted by applicable Requirement of Law, to take, or refrain from taking, as the case may be, each action necessary to be taken or not taken, as the case may be, so that no Default or Event of Default is caused by the failure to take such action or to refrain from taking such action by such Guarantor.

Section 17 Governing Law

This Guaranty and the rights and obligations of the parties hereto shall be governed by, and construed and interpreted in accordance with, the law of the State of New York.

Section 18 Submission to Jurisdiction; Service of Process

(a) Any legal action or proceeding with respect to this Guaranty, and any other Loan Document, may be brought in the courts of the State of New York or of the United

Guaranty
Orbital Sciences Corporation

States of America for the Southern District of New York, and, by execution and delivery of this Guaranty, each Guarantor hereby accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of the aforesaid courts. The parties hereto hereby irrevocably waive any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, that any of them may now or hereafter have to the bringing of any such action or proceeding in such respective jurisdictions.

(b) Each Guarantor hereby irrevocably consents to the service of any and all legal process, summons, notices and documents in any suit, action or proceeding brought in the United States of America arising out of or in connection with this Guaranty or any other Loan Document by the mailing (by registered or certified mail, postage prepaid) or delivering of a copy of such process to such Guarantor care of the Borrower at the Borrower’s address specified in Section 11.8 (Notices, Etc.) of the Credit Agreement. Each Guarantor agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(c) Nothing contained in this Section 18 (Submission to Jurisdiction; Service of Process) shall affect the right of the Administrative Agent or any other Guarantied Party to serve process in any other manner permitted by law or commence legal proceedings or otherwise proceed against a Guarantor in any other jurisdiction.

(d) If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in Dollars into another currency, the parties hereto agree, to the fullest extent they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase Dollars with such other currency at the spot rate of exchange quoted by the Administrative Agent at 11:00 a.m. (New York time) on the Business Day preceding that on which final judgment is given, for the purchase of Dollars, for delivery two Business Days thereafter.

Section 19 Waiver of Judicial Bond

To the fullest extent permitted by applicable law, the Guarantor waives the requirement to post any bond that otherwise may be required of any Guarantied Party in connection with any judicial proceeding to enforce such Guarantied Party’s rights to payment hereunder, security interest in or other rights to the Collateral or in connection with any other legal or equitable action or proceeding arising out of, in connection with, or related to this Guaranty and the Loan Documents to which it is a party.

Section 20 Certain Terms

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
Orbital Sciences Corporation

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 bill, bill 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

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.

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 7.11 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.
