c. Xxxxx has publicly disclosed all material information necessary for Buyer to be able to purchase or sell Shares in compliance with applicable federal securities laws.

2. If Buyer would be obligated to pay cash (other than payment of the Premium and except in the case of an Event of Default in which Buyer is the Defaulting Party or a Termination Event in which Buyer is the Affected Party, other than an (x) Event of Default of the type described in Section 5(a)(iii), (v), (vi) or (vii) of the Master Agreement or (y) a Termination Event of the type described in Section 5(b)(i), (ii), (iii), (iv), or (v) of the Master Agreement that in the case of either (x) or (y) resulted from an event or events outside Buyer’s control) to, or receive cash from, Seller pursuant to the terms of this Agreement for any reason without having had the right (other than pursuant to this paragraph (2), but including (x) the right to deliver Shares under the Note Indenture upon conversion of the Reference Notes or (y) the right to deliver or receive Shares in any other document or agreement that would result, directly or indirectly, in a cash payment hereunder) to elect to deliver or receive Shares in satisfaction of such payment obligation, then Buyer may elect (by giving notice to Seller no later than 8 a.m. New York time on the Exchange Business Day immediately following the date of occurrence of the ezvent giving rise to such payment obligation) that such payment obligation shall be satisfied by the delivery of a number of Shares (or, if the Shares have been converted into other securities or property in connection with an Extraordinary Event, a number or amount of such other securities or property as a holder of Shares would be entitled to receive upon the consummation or closing of such Extraordinary Event) having a cash value equal to the amount of such payment obligation. Such number of Shares or amount of other securities or property to be delivered shall be determined by the Calculation Agent to be the number of Shares or amount of such other securities or property that could be purchased or sold, as applicable, over a reasonable period of time with the cash equivalent of or producing the cash equivalent of such payment obligation). Settlement relating to any delivery of Shares or other securities or property pursuant to this paragraph (2) shall occur within a reasonable period of time.  Notwithstanding anything herein or in the Agreement to the contrary, the aggregate number of Shares that Counterparty may be required to deliver to Dealer under this Transaction shall not exceed the product of (a) 1.5 and (b) the Number of Shares, as adjusted by the Calculation Agent to account for any subdivision, stock-split, stock combination, reclassification or similar dilutive or anti-dilutive event with respect to the Shares.

5. The representations and warranties set forth in Section 1 of the Purchase Agreement (as defined herein) are hereby deemed to be repeated to Dealer as if set forth herein.

8

Additional Termination Events:

The occurrence of an Amendment Event or a Repayment Event shall be an Additional Termination Event with respect to which the Transaction is the sole Affected Transaction, Counterparty is the sole Affected Party and Dealer is the sole party entitled to designate an Early Termination Date; provided that in the case of a Repayment Event, the Transaction shall be subject to termination only in respect of the number of Reference Notes that cease to be outstanding in connection with or as a result of such Repayment Event:

1. “Amendment Event” means that the Counterparty, without Dealer’s consent, amends, modifies, supplements or obtains a waiver of (a) any term of the Note Indenture (as in effect prior to such amendment, modification, supplement or waiver) or the Reference Notes relating to the principal amount, coupon, maturity, repurchase obligation of the Counterparty or redemption right of the Counterparty, (b) any material term relating to conversion of the Reference Notes, including, without limitation, any changes to the conversion price, conversion settlement dates or conversion conditions or (c) any term that would require consent of the holders of 100% of the principal amount of the Reference Notes to amend.

2. “Repayment Event” means that (a) any Reference Notes are repurchased (whether in connection with or as a result of a fundamental change or change of control, howsoever defined, or for any other reason) by the Counterparty, (b) any Reference Notes are delivered to the Counterparty in exchange for delivery of any property or assets of the Counterparty or any of its subsidiaries (howsoever described), other than as a result of and in connection with a Conversion Date, (c) any principal of any of the Reference Notes is repaid prior to the Stated Maturity (as defined in the Note Indenture) (whether following acceleration of the Reference Notes or otherwise), provided that no payments of cash made in respect of the conversion of a Reference Note shall be deemed a payment of principal under this clause (c), (d) any Reference Notes are exchanged by or for the benefit of the holders thereof for any other securities of the Counterparty or any of its Affiliates (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction or (e) any of the Reference Notes is surrendered by Counterparty to the trustee for cancellation, other than registration of a transfer of such Reference Notes or as a result of and in connection with a Conversion Date.

3. Initial Purchase Event. If an Initial Purchase Event (as defined below) occurs, this Transaction shall terminate automatically in its entirety and, notwithstanding anything to the contrary herein, only the payments specified below shall be required hereunder in connection with such Initial Purchase Event.

“Initial Purchase Event” means that the transactions contemplated by the Purchase Agreement shall fail to close for any reason by the closing date for the offering of the Reference Notes as specified in the Purchase Agreement.

If an Initial Purchase Event occurs for any reason other than due to a breach of the Purchase Agreement by the Initial Purchasers, then all payments previously made hereunder shall be returned to the person making such payment, including the Premium, less an amount equal to the product of (a) the Number of Shares, (b) 0.50 and (c) an amount equal to the excess, if any, of the closing price of the Shares on the Trade Date over the closing price of the Shares on the date of the Termination Event (the “Break Expense”); provided that any negative amount shall be replaced by zero and provided further that to the extent the Premium has not been paid, Buyer shall promptly pay Seller the Break Expense. Seller and Xxxxx agree that actual damages would be difficult to ascertain under these circumstances and that the amount of liquidated damages resulting from the determination in the preceding sentence is a good faith estimate of such damages and not a penalty.

If an Initial Purchase Event occurs due to a breach of the Purchase Agreement by the Initial Purchasers, then all payments previously made hereunder, including the Premium, promptly shall be returned to the

9

person making such payment and no payments shall be required hereunder in connection with such Initial Purchase Event.

Staggered Settlement:

If Seller determines reasonably and in good faith that the number of Shares required to be delivered to Buyer hereunder on any Settlement Date would exceed 8.0% of all outstanding Shares, then Seller may, by notice to Buyer on or prior to such Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares comprising the related Delivery Obligation on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date as follows:

1. in such notice, Seller will specify to Buyer the related Staggered Settlement Dates (each of which will be such Nominal Settlement Date and the last of which will be no later than twenty (20) Trading Days following such Nominal Settlement Date) or delivery times and how it will allocate the Shares it is required to deliver hereunder among the Staggered Settlement Dates or delivery times;

2. the aggregate number of Shares that Seller will deliver to Buyer hereunder on all such Staggered Settlement Dates or delivery times will equal the number of Shares that Seller would otherwise be required to deliver on such Nominal Settlement Date; and

3. the procedures set forth above under the heading “Settlement Terms” will apply on each Staggered Settlement Date, except that the Shares comprising the Delivery Obligation will be allocated among such Staggered Settlement Dates or delivery times as specified by Seller in the notice referred to in clause (1) above.

Notwithstanding anything herein to the contrary, solely in connection with a Staggered Settlement Date, Seller shall be entitled to deliver Shares to Buyer from time to time prior to the date on which Seller would be obligated to deliver them to Buyer pursuant to the Delivery Obligation terms set forth above, and Xxxxx agrees to credit all such early deliveries against Seller’s obligations hereunder in the direct order in which such obligations arise. No such early delivery of Shares will accelerate or otherwise affect any of Buyer’s obligations to Seller hereunder.

Disposition of Hedge Shares:

Counterparty hereby agrees that if, in the reasonable judgment of Seller based on advice of counsel, the Shares acquired by Seller for the purpose of hedging its obligations pursuant to the Transaction (the “Hedge Shares”) cannot be sold in the U.S. public market by Seller without registration under the Securities Act, Counterparty shall, at its election: (i) in order to allow Seller to sell the Hedge Shares in a registered offering, make available to Seller an effective registration statement under the Securities Act to cover the resale of such Hedge Shares and (a) enter into an agreement, in form and substance satisfactory to Seller, substantially in the form of an underwriting agreement for a registered offering, (b) provide accountant’s “comfort” letters in customary form for registered offerings of equity securities, (c) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to Seller, (d) provide other customary opinions, certificates and closing documents customary in form for registered offerings of equity securities and (e) afford Seller a reasonable opportunity to conduct a “due diligence” investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities; provided, however, that if Seller, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or clause (iii) of this Section shall apply at the election of Counterparty; (ii) in order to allow Seller to sell the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance satisfactory to Seller, including customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Seller, due diligence rights (for Seller or any designated buyer of the Hedge Shares from Seller), opinions and certificates and such other documentation as is customary for private placements agreements, all reasonably acceptable to Seller (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary to compensate

10

Seller for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement); or (iii) purchase the Hedge Shares from Seller at the VWAP Price on such Exchange Business Days, and in such amounts, as requested by Seller. “VWAP Price” means, on any Exchange Business Day, the per Share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page AAR.N <equity> VAP (or any successor thereto) in respect of the period from 9:30 a.m. to 4:00 p.m. (New York City time) on such Exchange Business Day (or if such volume-weighted average price is unavailable, the market value of one Share on such Exchange Business Day, as determined by the Calculation Agent using a volume-weighted method).

Repurchase Notices:

Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Seller a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the Notice Percentage as determined on such day is (i) greater than 6% and (ii) greater by 0.5% than the Notice Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater than the Notice Percentage as of the date hereof). In the event that Counterparty fails to provide Seller with a Repurchase Notice on the day and in the manner specified in this section, then Counterparty agrees to indemnify and hold harmless Seller, its affiliates and their respective directors, officers, employees, agents and controlling persons (Seller and each such person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities (or actions in respect thereof), joint or several, to which such Indemnified Party may become subject under applicable securities laws, including without limitation, Section 16 of the Exchange Act, relating to or arising out of such failure. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability. In addition, Counterparty will reimburse any Indemnified Party for all reasonable and documented expenses (including reasonable counsel fees and expenses) as they are incurred (after notice to Counterparty) in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. This indemnity shall survive the completion of the Transaction contemplated by this Confirmation and any assignment and delegation of the Transaction made pursuant to this Confirmation or the Agreement shall inure to the benefit of any permitted assignee of Seller. Counterparty will not be liable under this Indemnity provision to the extent that any loss, claim, damage, liability or expense is found in a final judgment by a court to have resulted from Dealer’s gross negligence or willful misconduct. The “Notice Percentage” as of any day is the fraction, expressed as a percentage, (i) the numerator of which is the product of (a) the number of outstanding Reference Notes and (b) a number of Shares per Reference Note equal to the Conversion Rate (as defined in the Note Indenture) and (ii) the denominator of which is the number of Shares outstanding on such day.

Conversion Rate Adjustment Notices

In connection with any adjustments to the Conversion Rate under the terms of the Note Indenture, Counterparty shall provide to Dealer a copy of the notice of adjustment required to be delivered to the Trustee (as defined in the Note Indenture) pursuant to Section 9.11 of the Note Indenture concurrently with filing of such notice with the Trustee.

Transfer:

Buyer shall have the right to assign its rights and delegate its obligations hereunder with respect to any portion of this Transaction, subject to Seller’s consent, such consent not to be unreasonably withheld; provided that such assignment or transfer shall be subject to receipt by Seller of opinions and documents reasonably satisfactory to Seller and effected on terms reasonably satisfactory to the Seller with respect to any legal and regulatory requirements relevant to the Seller; provided further that Buyer shall not be released from its obligation to deliver any Exercise Notice or its obligations pursuant to “Disposition of Hedge Shares”, “Repurchase Notices” or “Conversion Rate Adjustment Notices” above.

Seller may transfer any of its rights or delegate its obligations under this Transaction with the prior written consent of Buyer, such consent not to be unreasonably withheld. In addition, if, as determined in Seller’s sole discretion, its “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and rules promulgated thereunder) could be deemed to exceed 8% of Counterparty’s outstanding Shares, Seller may, without Counterparty’s consent, transfer or assign all or any part of its rights or obligations under this Transaction to reduce such “beneficial ownership” to 7.5% to any third party with a rating for its (or, if applicable, its Credit Support Provider’s) long term, unsecured and unsubordinated indebtedness of AA or better by Standard & Poor’s Ratings Service or its successor (“S&P”), or Aa3 or better by Xxxxx’x Investors Service (“Moody’s”) or, if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Company and Seller. If after Seller’s commercially reasonable efforts, Seller is unable to effect such a transfer or assignment on pricing terms reasonably acceptable to Seller and within a time period reasonably acceptable to Seller of a sufficient number of Options to reduce Seller’s “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and rules promulgated thereunder) to 7.5% of Counterparty’s outstanding Shares or less, Seller may designate any Exchange Business Day as an Early Termination Date with respect to a portion (the “Terminated Portion”) of this Transaction, such that its “beneficial ownership” following such partial termination will be equal to or less than 7.5%. In the event that Seller so designates an Early Termination Date with respect to a portion of this Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the Terminated Portion, (ii) Counterparty shall be the sole Affected Party with respect to such partial termination and (iii) such Transaction shall be the only Terminated Transaction.

Matters Relating to Agent:

1. Agent will be responsible for the operational aspects of the Transactions effected through it, such as record keeping, reporting, and confirming Transactions to Xxxxx and Seller;

2. Unless Buyer is a “major U.S. institutional investor,” as defined in Rule 15a-6 of the Exchange Act, neither Buyer nor Seller will contact the other without the direct involvement of Agent;

3. Agent’s sole role under this Agreement and with respect to any Transaction is as an agent of Xxxxx and Seller on a disclosed basis and Agent shall have no responsibility or liability to Buyer or Seller hereunder except for gross negligence or willful misconduct in the performance of its duties as agent. Agent is authorized to act as agent for Buyer, but only to the extent expressly required to satisfy the requirements of Rule 15a-6 under the Exchange Act in respect of the Options described hereunder. Agent shall have no authority to act as agent for Buyer generally or with respect to transactions or other matters governed by this Agreement, except to the extent expressly required to satisfy the requirements of Rule 15a-6 or in

13

accordance with express instructions from Buyer.

Certain Important Information:

In the event of Dealer’s failure (by insolvency or otherwise), you would likely be considered to be an unsecured creditor of Dealer as to any collateral pledged to Dealer under the Agreement.

EXHIBIT A

GUARANTEE OF XXXXXXX XXXXX & CO., INC.

FOR VALUE RECEIVED, receipt of which is hereby acknowledged, XXXXXXX XXXXX & CO., INC., a corporation duly organized and existing under the laws of the State of Delaware (“ML & Co.”), hereby unconditionally guarantees to AAR Corp. (the “Company”), the due and punctual payment of any and all amounts payable by Xxxxxxx Xxxxx Financial Markets, Inc., a company incorporated in Delaware (“ML”), under the terms of the Confirmation of OTC Convertible Note Hedge between the Company and ML (ML as Seller), dated as of February 5, 2008, with respect to the Reference Notes (as defined therein) of Company due 2014 (the “Confirmation”), including, in case of default, interest on any amount due, when and as the same shall become due and payable, whether on the scheduled payment dates, at maturity, upon declaration of termination or otherwise, according to the terms thereof.  In case of the failure of ML punctually to make any such payment, ML  & Co. hereby agrees to make such payment, or cause such payment to be made, promptly upon demand made by the Company to ML & Co.; provided, however that delay by the Company in giving such demand shall in no event affect ML & Co.’s obligations under this Guarantee.  This Guarantee shall remain in full force and effect or shall be reinstated (as the case may be) if at any time any payment guaranteed hereunder, in whole or in part, is rescinded or must otherwise be returned by the Company upon the insolvency, bankruptcy or reorganization of ML or otherwise, all as though such payment had not been made.

ML & Co. hereby agrees that its obligations hereunder constitute a guarantee of payment when due and not of collection and that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Confirmation; the absence of any action to enforce the same; any waiver or consent by the Company concerning any provisions thereof; the rendering of any judgment against ML or any action to enforce the same; or any other circumstances that might otherwise constitute a legal or equitable discharge of a guarantor or a defense of a guarantor.  ML covenants that this guarantee will not be discharged except by complete payment of the amounts payable under the Confirmation.  This Guarantee shall continue to be effective if XX xxxxxx or consolidates with or into another entity, loses its separate legal identity or ceases to exist.

ML & Co. shall not exercise any rights that it may acquire by way of subrogation as a result of a payment by it under this Guarantee at any time when any of the obligations of ML shall have become due and remain unpaid. Any amount paid to ML & Co. in violation of the preceding sentence shall be held for the benefit of the Company and shall forthwith be paid to the Company to be credited and applied to such obligations of ML then due and unpaid.  Subject to the foregoing, upon payment of all such obligations of ML, ML & Co. shall be subrogated to the rights of the Company against ML, and the Company agrees to take at ML & Co.’s expense such steps as ML &Co. may reasonably request to implement such subrogation.

ML & Co. hereby waives diligence; presentment; protest; notice of protest, acceleration, and dishonor; filing of claims with a court in the event of insolvency or bankruptcy of ML; all demands whatsoever, except as noted in the first paragraph hereof; and any right to require a proceeding first against ML.

ML & Co. hereby certifies and warrants that this Guarantee constitutes the valid obligation of ML & Co.  and complies with all applicable laws.

This Guarantee shall be governed by, and construed in accordance with, the laws of the State of New York.

This Guarantee becomes effective concurrent with the effectiveness of the Confirmation, according to its terms.

IN WITNESS WHEREOF, ML & Co. has caused this Guarantee to be executed in its corporate name by its duly authorized representative.
