Kaman Corporation, a Connecticut corporation (the “Company”), proposes to issue and sell to the several initial purchasers listed in Schedule 1 hereto (the “Initial Purchasers”), for whom you are acting as representatives (the “Representatives”), $175,000,000 aggregate principal amount of its 3.25% Convertible Senior Notes due 2024 (the “Underwritten Securities”) and, at the option of the Initial Purchasers, up to an additional $25,000,000 aggregate principal amount of its 3.25% Convertible Senior Notes due 2024 (the “Option Securities”), solely to cover over-allotments, if and to the extent that the Initial Purchasers shall have determined to exercise the over-allotment option to purchase such 3.25% Convertible Senior Notes due 2024 granted to the Initial Purchasers in Section 2 hereof. The Underwritten Securities and the Option Securities are herein referred to as the “Securities”. The Securities will be convertible into cash, shares of common stock of the Company, par value $1.00 per share (the “Common Stock”), or a combination thereof, at the Company’s election, on the terms and subject to the conditions set forth in the Time of Sale Information and the Offering Memorandum (each as defined below). Any Common Stock into which the Securities are convertible are referred to herein as the “Underlying Securities.” The Securities will be issued pursuant to an Indenture to be dated as of May 12, 2017 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”).

In connection with the offering of the Underwritten Securities, the Company is separately entering into a capped call transaction with each of JPMorgan Chase Bank, National Association, London Branch, Bank of America, N.A. and UBS AG, London Branch (the “Capped Call

Counterparties”), in each case pursuant to a capped call confirmation (each, a “Base Capped Call Confirmation”), each to be dated the date hereof, and in connection with any exercise by the Initial Purchasers of their over-allotment option to purchase any Option Securities, the Company and each of the Capped Call Counterparties may enter into an additional capped call transaction pursuant to an additional capped call confirmation (each, an “Additional Capped Call Confirmation”), each to be dated the date on which the Initial Purchasers exercise their over-allotment option to purchase such Option Securities. We refer to the Base Capped Call Confirmations and the Additional Capped Call Confirmations collectively herein as the “Capped Call Confirmations.”

The Company hereby confirms its agreement with the several Initial Purchasers concerning the purchase and sale of the Securities, as follows:

1. Offering Memorandum and Transaction Information. The Securities will be sold to the Initial Purchasers without being registered under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon an exemption therefrom. The Company has prepared a preliminary offering memorandum dated May 8, 2017 (the “Preliminary Offering Memorandum”) and will prepare an offering memorandum dated the date hereof (the “Offering Memorandum”) setting forth information concerning the Company and the Securities. Copies of the Preliminary Offering Memorandum have been, and copies of the Offering Memorandum will be, delivered by the Company to the Initial Purchasers pursuant to the terms of this purchase agreement (this “Agreement”). The Company hereby confirms that it has authorized the use of the Preliminary Offering Memorandum, the other Time of Sale Information and the Offering Memorandum in connection with the offering and resale of the Securities by the Initial Purchasers in the manner contemplated by this Agreement. References herein to the Preliminary Offering Memorandum, the Time of Sale Information and the Offering Memorandum shall be deemed to refer to and include any document incorporated by reference therein and any reference to “amend,” “amendment” or “supplement” with respect to the Preliminary Offering Memorandum or the Offering Memorandum shall be deemed to refer to and include any documents filed after such date and incorporated by reference therein.

At or prior to the time when sales of the Securities were first made (the “Time of Sale”), the Company had prepared the following information (collectively, the “Time of Sale Information”): the Preliminary Offering Memorandum, as supplemented and amended by the written communications listed on Annex A hereto.

2. Purchase and Resale of the Securities. (a) The Company agrees to issue and sell the Underwritten Securities to the several Initial Purchasers as provided in this Agreement, and each Initial Purchaser, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Underwritten Securities set forth opposite such Initial Purchaser’s name in Schedule 1 hereto at a price equal to 96.75% of the principal amount thereof (the “Purchase Price”) plus accrued interest, if any, from May 12, 2017 to the Closing Date.

In addition, the Company agrees to issue and sell the Option Securities to the several Initial Purchasers as provided in this Agreement, and the Initial Purchasers, on the basis of the

representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Company the Option Securities at the Purchase Price plus accrued interest, if any, from May 12, 2017 to the date of payment and delivery, solely to cover over-allotments.

If any Option Securities are to be purchased, the principal amount of Option Securities to be purchased by each Initial Purchaser shall be the principal amount of Option Securities which bears the same ratio to the aggregate principal amount of Option Securities being purchased as the principal amount of Underwritten Securities set forth opposite the name of such Initial Purchaser in Schedule 1 hereto (or such amount increased as set forth in Section 10 hereof) bears to the aggregate principal amount of Underwritten Securities being purchased from the Company by the several Initial Purchasers, subject, however, to such adjustments to eliminate Securities in denominations other than $1,000 as the Representatives in their sole discretion shall make.

The Initial Purchasers may purchase the Option Securities at any time in whole, or from time to time in part, by written notice from the Representatives to the Company. Such notice shall set forth the aggregate principal amount of Option Securities plus accrued interest as to which the option is being exercised and the date and time when the Option Securities are to be delivered and paid for which may be the same date and time as the Closing Date (as hereinafter defined) but shall not be earlier than the Closing Date nor later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10 hereof); provided that in no event shall the delivery date of the Option Securities be later than the thirteenth day of the period beginning on, and including, the Closing Date. Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

(b) The Company understands that the Initial Purchasers intend to offer the Securities for resale on the terms set forth in the Time of Sale Information. Each Initial Purchaser, severally and not jointly, represents, warrants and agrees that:

(i) it is a qualified institutional buyer within the meaning of Rule 144A under the Securities Act (a “QIB”) and an accredited investor within the meaning of Rule 501(a) of Regulation D under the Securities Act (“Regulation D”);

(ii) it has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or sell, the Securities in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act; and

(iii) it has not sold the Securities as part of the initial offering except to persons whom it reasonably believes to be QIBs in transactions pursuant to Rule 144A under the Securities Act (“Rule 144A”) and in connection with each such sale, it has taken or will take reasonable steps to ensure that the purchaser of the Securities is aware that such sale is being made in reliance on Rule 144A.

(c) Each Initial Purchaser acknowledges and agrees that the Company and, for purposes of the “no registration” opinions to be delivered to the Initial Purchasers pursuant to Sections 6(g) and 6(i), counsel for the Company and counsel for the Initial Purchasers,

respectively, may rely upon the accuracy of the representations and warranties of the Initial Purchasers, and compliance by the Initial Purchasers with their agreements, contained in paragraph (b) above, and each Initial Purchaser hereby consents to such reliance.

(d) The Company acknowledges and agrees that the Initial Purchasers may offer and sell Securities to or through any affiliate of an Initial Purchaser and that any such affiliate may offer and sell Securities purchased by it to or through any Initial Purchaser.

(e) Payment for the Securities shall be made by wire transfer in immediately available funds to the account specified by the Company to the Representatives in the case of the Underwritten Securities, at the offices of Davis Polk & Wardwell LLP, 450 Lexington Avenue, New York, NY 10017, at 10:00 A.M. New York City time on May 12, 2017, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing or, in the case of the Option Securities, on the date and at the time and place specified by the Representatives in the written notice of the Initial Purchasers’ election to purchase such Option Securities. The time and date of such payment for the Underwritten Securities is referred to herein as the “Closing Date” and the time and date for such payment for the Option Securities, if other than the Closing Date, is herein referred to as the “Additional Closing Date”.

Payment for the Securities to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made against delivery to the nominee of The Depository Trust Company (“DTC”), for the respective accounts of the several Initial Purchasers of the Securities to be purchased on such date of one or more global notes representing the Securities (collectively, the “Global Note”), with any transfer taxes payable in connection with the sale of such Securities duly paid by the Company. The Global Note will be made available for inspection by the Representatives at the office of Davis Polk & Wardwell LLP set forth above not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date or the Additional Closing Date, as the case may be.

(f) The Company acknowledges and agrees that each Initial Purchaser is acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, neither the Representatives nor any other Initial Purchaser is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Initial Purchasers shall have no responsibility or liability to the Company with respect thereto. Any review by the Representatives or any Initial Purchaser of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representatives or such Initial Purchaser and shall not be on behalf of the Company or any other person.

Except as disclosed in the Time of Sale Information and the Offering Memorandum, there is no action, suit, proceeding, inquiry or investigation before or brought by any Governmental Entity now pending or, to the knowledge of the Company, threatened, against or affecting the Company or any of its Subsidiaries, which would reasonably be expected to result in a Material Adverse Effect, or which would reasonably be expected to materially and adversely affect their respective properties or assets or the consummation of the transactions contemplated by the Transaction Documents or the performance by the Company of its obligations under the Transaction Documents; and the aggregate of all pending legal or governmental proceedings to which the Company or any such Subsidiary is a party or of which any of their respective properties or assets is the subject which are not described in the Time of Sale Information and the Offering Memorandum, including ordinary routine litigation incidental to the business, would not reasonably be expected to result in a Material Adverse Effect.

(y) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any Governmental Entity is necessary or required for the performance by the Company of its obligations hereunder, in

connection with the offering, issuance or sale of the Securities hereunder by the Company (including the issuance of any Underlying Securities upon conversion thereof) or the consummation by the Company of the transactions contemplated by the Transaction Documents or for the due execution, delivery and performance by the Company of the Transaction Documents, except such as have been already obtained.

The Company and its Subsidiaries are in compliance with the terms and conditions of all Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. All of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any of its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to result in a Material Adverse Effect.

(b) Indemnification of the Company. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information (including any of the other Time of Sale Information that has subsequently been amended), any Issuer Written Communication, any Permitted General Solicitation, any road show or the Offering Memorandum (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished by any Initial Purchaser consists of the following information in the Offering Memorandum furnished on behalf of each Initial Purchaser: the information contained in the first paragraph under the caption “Plan of Distribution—Price stabilization and short positions”.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure

to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its officers and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) or (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other, from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on the one hand, and the Initial Purchasers, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company, on the one hand, and the Initial Purchasers, on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective as of the date first written above.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date or, in the case of the Option Securities, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the Exchange or The NASDAQ Global Market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum.

10. Defaulting Initial Purchaser. (a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder on such date, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be does not exceed one-eleventh of the aggregate number of Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the number of Securities that such Initial Purchaser agreed to purchase hereunder on such date plus such Initial Purchaser’s pro rata share (based on the number of Securities that such Initial

Purchaser agreed to purchase on such date) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate principal amount of Securities to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Initial Purchasers to purchase Securities on the Additional Closing Date, as the case may be, shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company or any non-defaulting Initial Purchaser for damages caused by its default.

11. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any stamp or similar taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer Written Communication, any Permitted General Solicitation and the Offering Memorandum (including any amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (x) all expenses and application fees related to the listing of the Underlying Securities on the Exchange.

(b) If (i) this Agreement is terminated pursuant to Section 9, (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company agrees to reimburse the Initial Purchasers for all out-of-pocket costs and expenses

(including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Initial Purchasers.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

15. Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients.

16. Miscellaneous. (a) Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication.

(b) Governing Law. This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the laws of the State of New York.

(c) Submission to Jurisdiction. The Company hereby submits to the exclusive jurisdiction of the U.S. federal and New York state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company waives any objection which it may now or hereafter have to the laying of venue of any such suit or proceeding in such courts.

Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court.

(d) Waiver of Jury Trial. Each of the parties hereto hereby waives any right to trial by jury in any suit or proceeding arising out of or relating to this Agreement.

The undersigned, Robert D.

Capitalized terms used but not defined in this certificate have the meaning ascribed to them in the Purchase Agreement.

The undersigned understands that you, as Representatives of the several Initial Purchasers, propose to enter into a Purchase Agreement (the “Purchase Agreement”) with Kaman Corporation, a Connecticut corporation (the “Company”), providing for the purchase and resale (the “Placement”) by the several Initial Purchasers named in Schedule 1 to the Purchase Agreement (the “Initial Purchasers”), of Convertible Senior Notes due 2024 of the Company (the “Securities”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Purchase Agreement.

In consideration of the Initial Purchasers’ agreement to purchase and make the Placement of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated on behalf of the Initial Purchasers, the undersigned will not, during the period ending 60 days after the date of the offering memorandum relating to the Placement (the “Offering Memorandum”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock, $1.00 per share par value, of the Company

(the “Common Stock”) or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant), or publicly disclose the intention to make any offer, sale, pledge or disposition, (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise or (3) make any demand for or exercise any right with respect to the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The foregoing restrictions shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the date of the Placement, provided that it shall be a precondition to any such transaction that no filing or other public announcement by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be voluntarily made in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions (other than a filing on a Form 5 made after the expiration of the 60 day period referred to above), (b) any transfer of any shares of Common Stock or other securities convertible into Common Stock made as a bona fide gift or gifts, provided that any such transfer does not involve a disposition for value, provided, further that any donee agrees to be bound in writing by the restrictions set forth herein and provided, further that if the donor is a reporting person subject to Section 16(a) of the Exchange Act, any gifts or transfers made in accordance with this clause (b) shall not require such person to, and such person shall not voluntarily, file a report of such transaction on Form 4 under the Exchange Act, (c) transfers to any trust or other estate planning vehicle for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that any such transfer does not involve a disposition for value, provided, further that any transferee agrees to be bound in writing by the restrictions set forth herein and provided, further that if the transferor is a reporting person subject to Section 16(a) of the Exchange Act, any transfers made in accordance with this clause (c) shall not require such person to, and such person shall not voluntarily, file a report of such transaction on Form 4 under the Exchange Act, (d) transfers by will, other testamentary document or intestate succession to the legal representative, heir beneficiary or member of the immediate family of the executive officer or director, provided that any transferee agrees to be bound in writing by the restrictions set forth herein, or (e) to the extent necessary, any sale or other disposition of shares of Common Stock to the Company solely to permit the undersigned to pay to the Company the exercise price and/or tax withholding obligation due upon the exercise and/or vesting of any award granted under a Company equity incentive plan in effect on the date hereof; provided that, if the undersigned reports any such sale or other disposition on a Form 4 filed with the SEC pursuant to Section 16 of the Exchange Act in reliance on this clause (e), then such Form 4 shall include a statement to the effect that such sale or other disposition was made to the Company solely to permit the undersigned to pay to the Company the exercise price and/or tax withholding obligation due upon the exercise and/or vesting of an award granted under a Company equity incentive plan. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and

registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

For purposes of this Letter Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption not more remote than first cousin.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that the Initial Purchasers are entering into the Purchase Agreement and proceeding with the Placement in reliance upon this Letter Agreement.

This Letter Agreement and any claim, controversy or dispute arising under or related to this Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.

CUSIP Number (144A):		483548 AE3

ISIN (144A):		US483548AE35

Use of Proceeds:		The Issuer estimates that the net proceeds from the offering will be approximately $168.4 million (or $192.6 million if the initial purchasers exercise their over-allotment option in full), after deducting fees and estimated expenses. The Issuer has entered into capped call transactions with one or more of the initial purchasers or their respective affiliates (the “option counterparties”). The Issuer intends to use approximately $17.9 million of the net proceeds from the offering to pay the cost of the capped call transactions. The Issuer intends to use the remainder of the net proceeds from the offering, along with cash received from existing option counterparties in connection with the partial unwind of the existing call spread transactions referred to below, to repay existing indebtedness, including using approximately $165.3 million to repurchase approximately $103.5 million principal amount of the Issuer’s convertible notes due on November 15, 2017 (the “existing convertible notes”) from a limited number of holders in privately negotiated transactions, which amount includes accrued and unpaid interest on such existing convertible notes to the date of repurchase. In connection with the existing convertible notes, the Issuer entered into convertible note hedge transactions and warrant transactions (the “existing call spread transactions”) with certain financial institutions (the “existing option counterparties”). In connection with the Issuer’s intended repurchase of existing convertible notes, the Issuer entered into agreements with the existing option counterparties to terminate a portion of such existing call spread transactions, in each case, in a notional amount corresponding to the amount of such existing convertible notes repurchased. In connection with any termination of existing call spread transactions and the related unwinding of the existing hedge position of the existing option counterparties with respect to such transactions, such existing option counterparties and/or their respective affiliates may sell shares of the Issuer’s common stock in secondary market transactions, and/or enter into or unwind various derivative transactions with respect to the Issuer’s common stock. This activity could decrease (or reduce the size of any increase in) the market price of the Issuer’s common stock at that time and it could decrease (or reduce the size of any increase in) the market value of the notes. In connection with these transactions, the Issuer expects to separately receive payments in connection with the partial unwind of such convertible note hedge transactions and expects to



		make deliveries of shares of the Issuer’s common stock in connection with the partial unwind of such warrant transactions, in each case, in amounts that depend on the market price of the Issuer’s common stock at such times as agreed with the existing option counterparties. If the initial purchasers exercise their over-allotment option, the Issuer expects to use the net proceeds from the sale of the additional Notes to enter into additional capped call transactions with the option counterparties and to repay indebtedness under the Issuer’s existing credit agreement. See “Use of proceeds” and “Risk factors—Risks related to the notes—Any repurchases of our existing convertible notes may affect the value of the notes and our common stock” in the Preliminary Offering Memorandum.
Increase in Conversion Rate Upon Conversion Upon a Make-Whole Fundamental Change:		Following the occurrence of a “make-whole fundamental change” (as defined in the Preliminary Offering Memorandum), the Issuer will, under certain circumstances, increase the Conversion Rate for a holder who elects to convert its Notes in connection with such make-whole fundamental change by a number of additional shares of common stock (the “additional shares”), as described under “Description of notes—Conversion rights—Increase in conversion rate upon conversion upon a make-whole fundamental change” in the Preliminary Offering Memorandum. The following table sets forth the number of additional shares by which the Conversion Rate will be increased per $1,000 principal amount of Notes for conversions in connection with a make-whole fundamental change for each stock price and effective date set forth below:
