While (i) neither the Issuer nor the Guarantor has or shall have an obligation to sell any Securities to the Dealer or to permit the Dealer to arrange any sale of the Securities for the account of the Issuer or the Guarantor, and (ii) the Dealer has and shall have no obligation to purchase the Securities from the Issuer or the Guarantor or to arrange any sale of the Securities for the account of the Issuer or the Guarantor, the parties hereto agree that in any case where the Dealer purchases Securities from the Issuer and the Guarantor, or arranges for the sale of Securities by the Issuer and the Guarantor, such Securities will be purchased or sold by the Dealer in reliance on the representations, warranties, covenants and agreements of the Issuer and the Guarantor contained herein or made pursuant hereto and on the terms and conditions and in the manner provided herein and sold by the Issuer and the Guarantor in reliance on the covenants and agreements of the Dealer contained herein or made pursuant hereto and on the terms and conditions and in the manner provided herein.

So long as this Agreement shall remain in effect, and in addition to the limitations contained in Section 1.7 hereof, neither the Issuer nor the Guarantor shall, without the consent of the Dealer, offer, solicit or accept offers to purchase, or sell, any Securities except (a) in transactions with one or more dealers which may from time to time after the date hereof become dealers with respect to the Securities by executing with the Issuer and the Guarantor one or more agreements which contain provisions substantially identical to those contained in Section 1 of this Agreement, of which the Issuer and the Guarantor hereby undertake to provide the Dealer prompt notice or (b) in transactions with the other dealers listed on the Addendum hereto, which are executing agreements with the Issuer and the

The Notes shall be in a minimum denomination of $250,000 or in integral multiples of $1,000 in excess thereof, will bear such interest rates, if interest bearing, or will be sold at such discount from their face amounts, as shall be agreed upon by the Dealer and the Issuer, shall have a maturity not exceeding 397 days from the date of issuance and may have such terms as are specified in Exhibit C hereto, the Private Placement Memorandum or a pricing supplement, or as otherwise agreed upon by the applicable purchaser and the Issuer. The Notes shall not contain any provision for extension, renewal or automatic “rollover.”

The authentication and issuance of, and payment for, the Notes shall be effected in accordance with the Issuing and Paying Agent Agreement, and the Notes shall be either individual physical certificates or book-entry notes evidenced by one or more master notes (each, a “Master Note”) registered in the name of The Depository Trust Company (“DTC”) or its nominee, in the form or forms annexed to the Issuing and Paying Agent Agreement.

If the Issuer and the Dealer shall agree on the terms of the purchase of any Note by the Dealer or the sale of any Note arranged by the Dealer (including, but not limited to, agreement with respect to the date of issue, purchase price, principal amount, maturity and interest rate or interest rate index and margin (in the case of interest-bearing Notes) or discount thereof (in the case of Notes issued on a discount basis), and appropriate compensation for the Dealer’s services hereunder) pursuant to this Agreement, the Issuer shall cause such Note to be issued and delivered in accordance with the terms of the Issuing and Paying Agent Agreement and payment for such Note shall be made by the purchaser thereof, either directly or through the Dealer, to the Issuing and Paying Agent, for the account of the Issuer. Except as otherwise agreed, in the event that the Dealer is acting as an agent and a purchaser shall either fail to accept delivery of or make payment for a Note on the date fixed for settlement, the Dealer shall promptly notify the Issuer, and if the Dealer has theretofore paid the Issuer for the Note, the Issuer will promptly return such funds to the Dealer against its return of the Note to the Issuer, in the case of a certificated Note, and upon notice of such failure in the case of a book-entry Note. If such failure occurred for any reason other than default by the Dealer, the Issuer and the Guarantor agree, jointly and severally, to reimburse the Dealer on an equitable basis for the Dealer’s loss of the use of such funds for the period such funds were credited to the Issuer’s account.

Each of the Dealer, the Issuer and the Guarantor hereby establishes and agrees to observe the following procedures in connection with offers, sales and subsequent resales or other transfers of the Notes:

Offers and sales of the Notes by or through the Dealer shall be made only to: (i) investors reasonably believed by the Dealer to be Qualified Institutional Buyers or Institutional Accredited Investors or (ii) non-bank fiduciaries or agents that will be purchasing Notes for one or more accounts, each of which is reasonably believed by the Dealer to be an Institutional Accredited Investor.

Resales and other transfers of the Notes by the holders thereof shall be made only in accordance with the restrictions in the legend described in clause (e) below.

No general solicitation or general advertising shall be used in connection with the offering of the Securities. Without limiting the generality of the foregoing, without the prior written approval of the Dealer, neither the Issuer nor the Guarantor shall issue any press release, make any other statement to any member of the press making reference to the Securities, the offer or sale of the Securities or this Agreement or place or publish any “tombstone” or other advertisement relating to the Securities or the offer and sale of the Securities. Notwithstanding the foregoing, (i) any publication by the Issuer or the Guarantor of a notice in accordance with Rule 135c under the Securities Act shall not be deemed to constitute general solicitation or general advertising hereunder and shall not require prior written approval of the Dealer (provided that the Issuer and/or the Guarantor shall provide a copy thereof to the Dealer at least three (3) business days prior to publication) and (ii) the Issuer and the Guarantor shall be permitted to make such filings with the SEC that the Issuer or the Guarantor reasonably determines are required to comply with Section 13 or 15(d) of the Exchange Act, and the Dealer acknowledges the Issuer intends to file a current report on Form 8-K on or about the date hereof with respect to transactions contemplated hereby; provided, however, that unless otherwise prohibited by applicable securities laws, rules and regulations, the Issuer and Guarantor shall omit the name of the Dealer from any publicly available filing (including the current report on Form 8-K) made by the Issuer or the Guarantor that makes reference to the Securities, the issuance, offer or sale of the Securities or this Agreement, including by redacting the Dealer’s name and any contact or other information that could identify the Dealer from any agreement or other information included in such filing. For the avoidance of doubt, neither the Issuer nor the Guarantor shall post the Private Placement Memorandum on a website without the consent of the Dealer and each other dealer or placement agent, if any, for the Securities.

No sale of Notes to any one purchaser shall be for less than $250,000 principal or face amount, and no Note shall be issued in a smaller principal or face amount. If the purchaser is a non-bank fiduciary acting on behalf of others, each person for whom such purchaser is acting must purchase at least $250,000 principal or face amount of Notes.

Offers and sales of the Securities shall be subject to the restrictions described in the legend appearing in Exhibit A hereto. A legend substantially to the effect of such Exhibit A shall appear as part of the Private Placement Memorandum used in connection with offers and sales of Securities hereunder, as well as on each individual certificate representing a Note and each Master Note representing book-entry Notes offered and sold pursuant to this Agreement.

The Dealer shall furnish or shall have furnished to each purchaser of any Notes for which it has acted as the dealer a copy of the then-current Private Placement Memorandum unless such purchaser has previously received a copy of the Private Placement Memorandum as then in effect. The Private Placement Memorandum shall expressly state that any person to whom Notes are offered shall have an opportunity to ask questions of, and receive information from, the Issuer, the Guarantor and the Dealer and shall provide the names, addresses and telephone numbers of the persons from whom information regarding the Issuer and the Guarantor may be obtained.

The Issuer and the Guarantor, jointly and severally, agree, for the benefit of the Dealer and each of the holders and prospective purchasers from time to time of the Notes, that, if at any time the Issuer or the Guarantor shall not be subject to Section 13 or 15(d) of the Exchange Act (other than by operation of an applicable exemption thereunder, such as Rule 12h-5), the Issuer and the Guarantor will furnish, upon request and at their expense, to the Dealer and to holders and prospective purchasers of Notes information required by Rule 144A(d)(4)(i) in compliance with Rule 144A(d).

In the event that any Security offered or to be offered by the Dealer would be ineligible for resale under Rule 144A, the Issuer shall promptly notify the Dealer (by telephone, confirmed in writing, or electronic mail) of such fact and shall promptly prepare and deliver to the Dealer an amendment or supplement to the Private Placement Memorandum describing the Securities that are ineligible, the reason for such ineligibility and any other relevant information relating thereto.

Each of the Issuer and the Guarantor also agrees that (except as permitted by Section 1.6(i)), as long as the Notes are being offered for sale by the Dealer and any Other Dealers as contemplated hereby, and until at least six months after the offer of Notes hereunder has been terminated, none of the Issuer, the Guarantor or any other person other than the Dealer or any Other Dealers (except as contemplated by Section 1.2 hereof) will offer the Securities or any substantially similar security of the Issuer or the Guarantor for sale to, or solicit offers to buy any such security from, any person other than the Dealer or any Other Dealers; provided that it is understood that such agreement is made with a view to bringing the offer and sale of the Securities within the exemption provided by Section 4(a)(2) of the Securities Act and shall survive any termination of this Agreement. Each of the Issuer and the Guarantor hereby represents and warrants that it has not taken or omitted to take, and will not take or omit to take, any action that would cause the offering and sale of Securities hereunder to be integrated with any other offering of securities, whether such offering is made by the Issuer, the Guarantor or some other party or parties.

The Issuer represents and agrees that the proceeds of the sale of the Notes are not currently contemplated to be used for the purpose of buying, carrying or trading securities within the meaning of Regulation T and the interpretations thereunder by the Board of Governors of the Federal Reserve System.

Each Program Document to which the Issuer or the Guarantor is party has been duly authorized, executed and delivered by the Issuer or the Guarantor, as applicable, and constitutes the legal, valid and binding obligations of the Issuer or the Guarantor, as applicable, enforceable against the Issuer or the Guarantor in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and other similar laws affecting creditors’ rights generally, and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law) and limitations on rights to indemnity and contribution imposed by applicable law.

The Notes have been duly authorized, and when issued as provided in the Issuing and Paying Agent Agreement, will be duly and validly issued and constitute legal, valid and binding obligations of the Issuer enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and other similar laws relating to or affecting creditors’ rights generally, and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law).

Assuming compliance by the Dealer with the requirements applicable to it set forth in Section 1.6 of this Agreement, the offer and sale of the Notes and the Guaranty in the manner contemplated hereby do not require registration of the Notes or the Guaranty under the Securities Act, pursuant to the exemption from registration contained in Section 4(a)(2) thereof, and no indenture in respect of the Notes or the Guaranty is required to be qualified under the Trust Indenture Act of 1939, as amended.

Assuming compliance by the Dealer with the requirements applicable to it set forth in Section 1.6 of this Agreement, no consent or action of, or filing or registration with, any governmental or public regulatory body or authority having jurisdiction over the Issuer or the Guarantor, as applicable, is required to authorize, or is otherwise required in connection with, the execution and delivery of any Program Document to which the Issuer or the Guarantor is party or the consummation of the transactions contemplated thereby, including the issuance and sale of the Notes and the issuance of the Guaranty, except (i) for the filing by the Issuer or the Guarantor of a current report on Form 8-K with the SEC if the Issuer or Guarantor reasonably determines such a filing is required, (ii) as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Notes and (iii) as have already been obtained.

Neither the execution and delivery of any Program Document to which the Issuer or the Guarantor is party nor the consummation of the transactions contemplated thereby, including the issuance and sale of the Notes and the issuance of the Guaranty will (i) result in the creation or imposition of any mortgage, lien, charge or encumbrance of any nature whatsoever upon any of the properties or assets of the Issuer or the Guarantor, as applicable, or (ii) violate or result in a breach or a default under (A) any of the terms of the organizational documents of the Issuer or the Guarantor, (B) any contract or instrument to which the Issuer or the Guarantor is party or by which it or its property is bound or (C) any law or regulation, or any order, writ, injunction or decree of any court or government instrumentality to which the Issuer or the Guarantor is subject or by which it or its property is bound, in each case, which violation, breach or default could reasonably be expected to have a material adverse effect on the condition (financial or otherwise), operations or business prospects of the Issuer or the Guarantor, or the ability of the Issuer or the Guarantor, as applicable, to perform any of its obligations hereunder or under any other Program Document to which it is party.

There is no litigation or governmental proceeding pending, or to the knowledge of the Issuer or the Guarantor threatened, against or affecting the Issuer or the Guarantor or any of their respective subsidiaries (other than that which is disclosed in the Company Information) which could reasonably be expected to have material adverse effect on the condition (financial or otherwise), operations or business prospects of the Issuer or the Guarantor, or the ability of the Issuer or the Guarantor, as applicable, to perform any of its obligations hereunder or under any other Program Document to which it is party.

Neither the Issuer nor the Guarantor is required to be registered as an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended.

None of the Issuer, the Guarantor any of their respective subsidiaries, directors or officers or, to the knowledge of the Issuer or the Guarantor, any agent, employee or affiliate of the Issuer, the Guarantor, or any of their respective subsidiaries, is currently subject to any sanctions administered or enforced by the United States Government, including, without limitation, the U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”), the United Nations Security Council, the European Union, Her Majesty’s Treasury, or other relevant sanctions authority (collectively, “Sanctions”); and neither the Issuer, the Guarantor nor any of their respective subsidiaries will directly or indirectly use the proceeds of the offering of the Securities hereunder, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, (i) for the purpose of financing the activities of any person or in any country or territory subject to any Sanctions or (ii) in any manner that will result in a violation of any economic Sanctions by, or could result in the imposition of Sanctions against, any person (including any person participating in the offering of Notes, whether as dealer, advisor, investor or otherwise).

Except as has been disclosed to the Dealer or is not material to the analysis under any Sanctions, neither the Issuer, the Guarantor nor any of their respective subsidiaries or affiliates has engaged in any dealings or transactions with or for the benefit of a person subject to any Sanctions or with or in a country subject to any Sanctions, in the preceding 3 years.

Neither the Issuer, the Guarantor nor any of their respective subsidiaries, directors or officers nor, to the knowledge of the Issuer or the Guarantor, any agent, employee, affiliate or other person associated with or acting on behalf of the Issuer, the Guarantor or any of their respective subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a violation by such persons of (i) the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (collectively, the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate

The Guarantor will receive financial benefits from the issuance of the Notes by the Issuer and the issuance by the Guarantor of the Guaranty in respect of the Notes.

Each (a) issuance of Notes by the Issuer hereunder and (b) amendment or supplement of the Private Placement Memorandum shall be deemed a representation and warranty by each of the Issuer and the Guarantor to the Dealer, as of the date thereof, that, both before and after giving effect to such issuance and after giving effect to such amendment or supplement, (i) the representations and warranties given by the Issuer and the Guarantor set forth in this Section 2 remain true and correct on and as of such date as if made on and as of such date, (ii) in the case of an issuance of Notes, the Notes being issued on such date have been duly and validly issued and constitute the legal, valid and binding obligations of the Issuer, enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and other similar laws affecting creditors’ rights generally and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law) and are guaranteed pursuant to the Guaranty and (iii) in the case of an issuance of Notes, since the date of the most recent Private Placement Memorandum, there has been no material adverse change in the condition (financial or otherwise),

Covenants and Agreements of the Issuer and the Guarantor.

The Issuer and the Guarantor will give the Dealer prompt notice (but in any event prior to any subsequent issuance of Notes hereunder) of any amendment to, modification of or waiver with respect to, the Notes, the Guaranty or the Issuing and Paying Agent Agreement, including a complete copy of any such amendment, modification or waiver.

Upon the occurrence of any change in the condition (financial or otherwise), operations or business prospects of the Issuer or the Guarantor that would be reasonably likely to be material to holders of the Notes or potential holders of the Notes (including any public announcement of any downgrading in the rating assigned to any of securities of the Issuer or the Guarantor by any nationally recognized statistical rating organization (as such term is defined in Section 3(a)(62) of the Exchange Act) which has published a rating of the Notes), the Issuer and the Guarantor shall promptly, and in any event prior to any issuance of Notes subsequent to the occurrence of any such change, notify the Dealer (by telephone, confirmed in writing, or electronic mail) of the occurrence of such change.

The Issuer and the Guarantor shall from time to time furnish to the Dealer such information as the Dealer may reasonably request (which information can be provided without unreasonable effort or expense), including, without limitation, any press releases or material provided by the Issuer or the Guarantor to any national securities exchange or rating agency, regarding (i) the operations and financial condition of the Issuer or the Guarantor, (ii) the due authorization and execution of the Notes and the Guaranty, (iii) the Issuer’s ability to pay the Notes as they mature and (iv) the Guarantor’s ability to fulfill its obligations under the Guaranty.

The Issuer and the Guarantor will take all such action as the Dealer may reasonably request to ensure that each offer and each sale of the Notes will comply with any applicable state Blue Sky laws; provided, however, that neither the Issuer nor the Guarantor shall be obligated to file any general consent to service of process or to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

Neither the Issuer nor the Guarantor will be in default of any of its obligations hereunder, under any other Program Document to which it is a party or under any Securities at any time that any Notes are outstanding, which, in the case of a default under any Program Document to which it is a party, could reasonably be expected to have a material adverse effect on the ability of the Issuer or the Guarantor, as applicable, to perform any of its obligations under any Program Document to which it is a party or to make payment on the Securities as and when such payment is due.

The Issuer shall not issue Notes hereunder until the Dealer shall have received:

prior to the issuance of any book-entry Notes represented by the Master Note, an executed copy of the Letter of Representations to DTC executed by the Issuer, the Guarantor and the Issuing and Paying Agent and the executed Master Note;

prior to the issuance of any Notes in physical form, a copy of such form (unless attached to this Agreement or the Issuing and Paying Agent Agreement);

confirmation of the then current rating assigned to the Notes by each nationally recognized statistical rating organization then rating the Notes; and

such other certificates, opinions, letters and documents as the Dealer shall have reasonably requested.

The Issuer and the Guarantor, jointly and severally, shall reimburse the Dealer for all of the Dealer’s reasonable and documented out-of-pocket expenses related to this Agreement, including reasonable expenses incurred in connection with its preparation and negotiation, and the transactions contemplated hereby (including, but not limited to, the printing and distribution of the Private Placement Memorandum), and, if applicable, for the reasonable fees and out-of-pocket expenses of the Dealer’s external counsel.

Each of the Issuer and the Guarantor agrees to promptly furnish the Dealer the Company Information as it becomes available; provided that any Company Information publicly filed with the SEC shall be deemed to have been delivered to the Dealer upon such Company Information being accessible through EDGAR.

(a)    Each of the Issuer and the Guarantor agrees to notify the Dealer promptly upon the occurrence of any event relating to or affecting the Issuer or the Guarantor that would cause the Company Information (other than Dealer Information) then in existence to include an untrue statement of a material fact or to omit to state a material fact necessary in order to make the statements contained therein, in light of the circumstances under which they are made, not misleading. Following the delivery of any such notice by the Issuer and/or the Guarantor, all

From and after the effective date of any Replacement, (A) to the extent that the Issuing and Paying Agent Agreement provides that the Current Issuing and Paying Agent will continue to act in respect of Notes outstanding as of the effective date of such Replacement (the “Outstanding Notes”), then (i) the “Issuing and Paying Agent” for the Notes shall be deemed to be the Current Issuing and Paying Agent, in respect of the Outstanding Notes, and the Replacement Issuing and Paying Agent, in respect of Notes issued on or after the Replacement, (ii) all references to the “Issuing and Paying Agent” hereunder shall be deemed to refer to the Current Issuing and Paying Agent in respect of the Outstanding Notes, and the Replacement Issuing and Paying Agent in respect of Notes issued on or after the Replacement, and (iii) all references to the “Issuing and Paying Agent Agreement” hereunder shall be deemed to refer to the existing Issuing and Paying Agent Agreement, in respect of the Outstanding Notes, and the Replacement Issuing and Paying Agent Agreement, in respect of Notes issued on or after the Replacement; and (B) to the extent that the Issuing and Paying Agent Agreement does not provide that the Current Issuing and Paying Agent will continue to act in respect of the Outstanding Notes, then (i) the “Issuing and Paying Agent” for the Notes shall be deemed to be the Replacement Issuing and Paying Agent, (ii) all references to the “Issuing and Paying Agent” hereunder shall be deemed to refer to the Replacement Issuing and Paying Agent, and (iii) all references to the “Issuing and Paying Agent Agreement” hereunder shall be deemed to refer to the Replacement Issuing and Paying Agent Agreement.

Notwithstanding anything to the contrary in this Agreement, the parties hereto agree that:

In the event that the Dealer is a Covered Entity and becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from the Dealer of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

In the event that the Dealer is a Covered Entity and the Dealer, or a BHC Act Affiliate of the Dealer, becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against the Dealer are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

following additional clauses shall apply to the Agreement and be deemed a part thereof.

The other dealers referred to in clause (b) of Section 1.2 of the Agreement are                             .

The addresses of the respective parties for purposes of notices under Section 7.1 are as follows:

The Issuer and the Guarantor, jointly and severally, agree to reimburse each Indemnitee for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of external counsel) as they are incurred by it in connection with investigating or defending any loss, claim, damage, liability or action in respect of which indemnification may be sought under Section 5 of the Agreement (whether or not it is a party to any such proceedings).

Promptly after receipt by an Indemnitee of notice of the existence of a Claim, such Indemnitee will, if a claim in respect thereof is to be made against the Issuer or the Guarantor, notify the Issuer and the Guarantor in writing of the existence thereof; provided that (i) the omission to so notify the Issuer or the Guarantor will not relieve the Issuer or the Guarantor from any liability which it may have hereunder unless and except to the extent it did not otherwise learn of such Claim and such failure results in the forfeiture by the Issuer of substantial rights and defenses, and (ii) the omission to so notify the Issuer or the Guarantor will not relieve it from liability which it may have to an Indemnitee otherwise than on account of this indemnity agreement. In case any such Claim is made against any Indemnitee and it notifies the Issuer and the Guarantor of the existence thereof, the Issuer and the Guarantor will be entitled to participate therein, and to the extent that it may elect by written notice delivered to the Indemnitee, to assume the defense thereof, with counsel selected by the Issuer and the Guarantor (which counsel shall be reasonably satisfactory to such Indemnitee); provided that if the defendants in any such Claim include both the Indemnitee and either the Issuer or the Guarantor, and the Indemnitee shall have concluded that there may be legal defenses available to it which are different from or additional to those available to the Issuer or the Guarantor, neither the Issuer nor the Guarantor, as applicable, shall have the right to direct the defense of such Claim on behalf of such Indemnitee, and the Indemnitee shall have the right to select separate counsel to assert such legal defenses on behalf of such Indemnitee. Upon receipt of notice from the Issuer or the Guarantor to such Indemnitee of the election by the Issuer or the Guarantor to assume the defense of such Claim and approval by the Indemnitee of such counsel, neither the Issuer nor the Guarantor will be liable to such Indemnitee for expenses incurred thereafter by the Indemnitee in connection with the defense thereof (other than reasonable costs of investigation) unless (i) the Indemnitee shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that neither the Issuer nor the Guarantor shall be liable for the expenses of more than one separate counsel (in addition to any local counsel in the jurisdiction in which any Claim is brought), approved by the Dealer, representing the Indemnitee who is party to such Claim), (ii) neither the Issuer nor the Guarantor shall have employed counsel reasonably satisfactory to the Indemnitee to represent the Indemnitee within a reasonable time after notice of existence of the Claim or (iii) either the Issuer or the Guarantor has authorized in writing the employment of counsel for the Indemnitee. Notwithstanding anything herein to the contrary, all of the Indemnitees who are party to the same Claim shall utilize the same counsel unless any such Indemnitee shall have concluded that there may be

Unlike single payment notes, where a default arises only at the stated maturity, interest-bearing notes with multiple payment dates should contain a default provision permitting acceleration of the maturity if the Issuer defaults on an interest payment.

a certificate from a duly authorized officer of the Issuer and the Guarantor confirming that no changes have been made to the organizational documents of the Issuer or the Guarantor, as applicable, since the date of the Dealer Agreement or, if there have been any changes, a certified copy of the related organizational documents currently in force;

certified copies of all documents evidencing the internal authorization and approval required to be granted by the Issuer and the Guarantor for such an increase in the Maximum Amount;

a list of names, titles and specimen signatures of the persons authorized to sign on behalf of the Issuer and Guarantor all notices and other documents to be delivered in connection with such an increase in the Maximum Amount to the extent there is a change in such persons following the increase in the Maximum Amount;

an updated or supplemental Private Placement Memorandum reflecting the increase in the Maximum Amount of the Program;

an opinion of counsel to the Issuer and the Guarantor as to (A) the due authorization, validity and enforceability of Notes issued pursuant to the Issuing and Paying Agent Agreement and the Guaranty, and (B) such other matters as the Dealer may reasonably request, in each case after giving effect to the increase in the Maximum Amount; and

evidence from each nationally recognized statistical rating organization providing a rating of the Notes either (A) that such rating has been confirmed after giving effect to the increase in the Maximum Amount or (B) setting forth any change in the rating of the Notes after giving effect to the increase in the Maximum Amount.

The Guarantor irrevocably guarantees payment in full, as and when the same becomes due and payable, of the principal of and interest, if any, on the short-term promissory notes (the “Notes”) issued by Leidos, Inc., a Delaware corporation and wholly-owned subsidiary of the Guarantor (the “Issuer”), from time to time pursuant to the Issuing and Paying Agent Agreement, dated as of [             ], 2021 (as the same may be amended, supplemented, modified or replaced from time to time, the “Agreement”), among                     , the Issuer and the Guarantor

The Guarantor’s obligations under this Guaranty shall be unconditional, irrespective of the validity or enforceability of any provision of the Agreement or the Notes.

This Guaranty is a guaranty of the due and punctual payment (and not merely of collection) of the principal of and interest, if any, on the Notes by the Issuer and shall remain in full force and effect until all amounts have been validly, finally and irrevocably paid in full, and shall not be affected in any way by any circumstance or condition whatsoever, including without limitation (a) the absence of any action to obtain such amounts from the Issuer, (b) any variation, extension, waiver, compromise or release of any or all of the obligations of the Issuer under the Agreement of the Notes or of any collateral security therefore or (c) any change in the existence or structure of, or the bankruptcy or insolvency of, the Issuer or by any other circumstance (other than by complete, irrevocable payment) that might otherwise constitute a legal or equitable discharge or defense of a guarantor or surety. The Guarantor waives all requirements as to diligence, presentment, demand for payment, protest and notice of any kind with respect to the Agreement and the Notes.

In the event of a default in payment of principal of or interest on any Notes, the holders of such Notes, may institute legal proceedings directly against the Guarantor to enforce this Guaranty without first proceeding against the Issuer.

This Guaranty shall remain in full force and effect or shall be reinstated (as the case may be) if at any time any payment by the Issuer of the principal of or interest, if any, on the Notes, in whole or in part, is rescinded or must otherwise be returned by the holder upon the insolvency, bankruptcy or reorganization of the Issuer or otherwise, all as though such payment had not been made.

This Guaranty shall be governed by and construed in accordance with the laws of the State of New York, without regard to its conflict of laws provisions.

The Guarantor hereby irrevocably accepts and submits to the non-exclusive jurisdiction of the United States federal courts located in the Borough of Manhattan and the courts of the State of New York located in the Borough of Manhattan with respect to any suit, action or proceeding in connection with or arising out of, this Guaranty.
