Delivery of the Notes will be made at the offices of Ballard Spahr LLP, 1735 Market Street, 51st Floor, Philadelphia, Pennsylvania 19103, or at such place or places as mutually may be agreed upon by the Company and the Initial Purchasers, at 10:00 A.M., New York City time, on December 4, 2025 or on such later date not more than three Business Days after such date as may be determined by the Representatives and the Company (the “Closing Date”). Payment for any Additional Notes shall be made to the Company against delivery of such Additional Notes for the respective accounts of the several Initial Purchasers at 10:00 A.M., New York City time, on the Option Closing Date. Delivery of the Notes will be made to the Representatives by or on behalf of the Company against payment of the purchase price therefor by wire transfer of immediately available funds. Delivery of the Notes will be made through the facilities of The Depository Trust Company unless
13 the Representatives will otherwise instruct. Delivery of the Notes at the time and place specified in this Agreement is a further condition to the obligations of each Initial Purchaser. 5. Reserved. 6. Conditions to the Initial Purchasers’ Obligations. The obligation of each Initial Purchaser to purchase the Notes on the Closing Date shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein as of the Applicable Time and the Closing Date, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, and to the performance by the Company of its covenants and other obligations hereunder and to the following additional conditions: (a) No stop order or decree preventing or suspending the qualification of the Notes for offering or sale in any jurisdiction will have been issued. (b) No Initial Purchaser will have been advised by the Company, or will have discovered and disclosed to the Company, that the Disclosure Package, the Offering Memorandum, any Issuer Written Information or any amendment or supplement thereto contains an untrue statement of fact which, in the opinion of the Representatives or of counsel to the Initial Purchasers, is material, or omits to state any fact which, in the opinion of the Representatives or of counsel to the Initial Purchasers, is material and is required to be stated therein or is necessary to make the statements therein not misleading. (c) Ballard Spahr LLP, special counsel for the Company, shall have furnished to the Representatives its opinion, including a negative assurance statement, dated the Closing Date, in substantially the form set forth in Schedule III. (d) The Representatives shall have received from Winston & Strawn LLP, counsel for the Initial Purchasers, such opinion or opinions, including a negative assurance statement, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Notes, the Indenture, the Offering Memorandum and Disclosure Package and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. In rendering such opinion, Winston & Strawn LLP may rely, as to matters governed by the laws of the Commonwealth of Pennsylvania, upon the opinion of counsel for the Company referred to in Section 6(c). (e) The Representatives shall have received from Davis Polk & Wardwell LLP, special product counsel for the Initial Purchasers, dated the Closing Date and addressed to the Representatives, such opinion or opinions with respect to such matters as may be reasonably required by the Initial Purchasers and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. In rendering such opinion, Davis Polk & Wardwell LLP may rely, as to matters governed by the laws of the Commonwealth of Pennsylvania, upon the opinion of counsel for the Company referred to in Section 6(c);
14 (f) The Company shall have furnished to the Representatives a certificate of the Company, signed by two officers, who shall be any of the chief executive officer, the principal financial officer, the principal accounting officer, the chief strategy officer, the treasurer or an assistant treasurer of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Disclosure Package, the Offering Memorandum and that: (i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date, with the same effect as if made on the Closing Date and the Company has complied in all material respects with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date; (ii) the signers of such certificate have carefully examined the Disclosure Package and the Offering Memorandum, and any amendments or supplements thereto (including any documents incorporated or deemed to be incorporated by reference into the Disclosure Package and the Offering Memorandum), and, in their opinion, the Disclosure Package, as of the Applicable Time, and the Offering Memorandum, as of its date, did not and, on the Closing Date, will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (iii) since the date of the Preliminary Offering Memorandum, there has occurred no event required to be set forth in an amendment or supplement to the Disclosure Package or the Offering Memorandum which has not been so set forth and there has been no document required to be filed under the Securities Act and the Rules and Regulations or the Exchange Act and the rules and regulations thereunder that upon such filing would be deemed to be incorporated by reference into the Disclosure Package or the Offering Memorandum that has not been so filed; and (iv) since the date of the most recent financial statements included or incorporated by reference in the Disclosure Package and the Offering Memorandum (exclusive of any amendment or supplement thereto), there has been no Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Offering Memorandum (exclusive of any amendment or supplement thereto). (g) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date: (i) there shall not have occurred any downgrading, nor shall the Company have received any notice from any “nationally recognized statistical rating organization,” as such term is defined in Section 3(a)(62) under the Exchange Act of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded the Company or any of the securities of the Company or any of its subsidiaries or in the rating outlook for the Company; and (ii) there shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company and its subsidiaries, taken as a whole, from that set forth in the Disclosure Package that, in the judgment of the Representatives, is material and adverse
15 and that makes it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offer, sale and delivery of the Notes on the terms and in the manner contemplated in the this agreement and the Disclosure Package. (h) The Initial Purchasers shall have received, on each of the date hereof and the Closing Date, a letter dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to the Initial Purchasers, from PricewaterhouseCoopers LLP, independent public accountants of the Company, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to Initial Purchasers with respect to the financial statements and certain financial information contained in the Disclosure Package and the Offering Memorandum; provided that the letter delivered on the Closing Date shall use a “cut-off date” not earlier than three business days prior to the Closing Date. (i) On the Closing Date, the Initial Purchasers shall have received a fully executed copy of each Transaction Agreement. (j) The Company shall have executed and delivered each Transaction Agreement, in form and substance reasonably satisfactory to the Initial Purchasers, and the Initial Purchasers shall have received executed copies thereof. (k) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request. If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Representatives and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing. (l) A number of shares of Common Stock equal to the Maximum Number of Underlying Common Stock shall have been approved for listing on the Exchange, subject only to official notice of issuance, if required. The obligations of the Initial Purchasers to purchase Additional Notes hereunder are subject to the delivery to the Representatives on the applicable Option Closing Date of such documents as the Representatives may reasonably request with respect to the good standing of the Company, the due authorization and issuance of the Additional Notes to be sold on such Option Closing Date and other matters related to the issuance of such Additional Notes. 7. Covenants of the Company. The Company covenants with each Initial Purchaser that: (a) The Company (i) will prepare each of the Preliminary Offering Memorandum and the Offering Memorandum in a form approved by the Representatives; (ii) will not file any document under the Exchange Act before the completion of the distribution of the Notes by the Initial Purchasers if such document would be deemed to be incorporated by reference into the Disclosure Package or the Offering Memorandum, which filing is not consented to by the
16 Representatives after reasonable notice thereof (such consent not to be unreasonably withheld or delayed); (iii) will prepare the Final Term Sheet, substantially in the form of Schedule II hereto and approved by the Representatives; (iv) will advise the Representatives promptly after it receives notice thereof, of the issuance by the Commission or any state or other regulatory body of any order or decree preventing or suspending the use of the Preliminary Offering Memorandum, the Disclosure Package or the Offering Memorandum; and (v) will use its best efforts to prevent the issuance of any such order and, if such order is issued, to obtain as soon as possible the lifting or withdrawal thereof. (b) The Company will prepare, promptly upon the request of the Representatives, any amendments or supplements to the Disclosure Package or the Offering Memorandum which, in the opinion of the Representatives, may be necessary or advisable in connection with the offering of the Notes. (c) The Company will furnish to each of the Representatives and to counsel for the Initial Purchasers such number of conformed copies of the Preliminary Offering Memorandum, the Disclosure Package, the Offering Memorandum and any Issuer Written Information and all amendments or supplements to any of such documents (including any document filed under the Exchange Act and deemed to be incorporated by reference in the Disclosure Package or the Offering Memorandum), in each case as soon as available and in such quantities as the Representatives may from time to time reasonably request. (d) If at any time prior to completion of the distribution of the Notes any event occurs as a result of which the Disclosure Package or the Offering Memorandum as then amended or supplemented would include or incorporate by reference an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary to amend or supplement the Disclosure Package or the Offering Memorandum, the Company will promptly notify the Representatives and will, subject to Section 7(a) hereof, amend or supplement the Disclosure Package or the Offering Memorandum, as the case may be, (at the expense of the Company) so as to correct such statement or omission or to effect such compliance, and will furnish without charge to each Initial Purchaser as many written and electronic copies of any such amendment or supplement as the Representatives may from time to time reasonably request. (e) As soon as practicable, the Company will make generally available to the Initial Purchasers and its security holders all the information specified in, and meeting the requirements of, Rule 144A(d)(4) under the Securities Act; provided, however, that, so long as the Company files periodic reports pursuant to Section 13 or 15(d) of the Exchange Act for the foregoing periods, the Company will be deemed to comply with this Section 7(e). (f) The Company will, whether or not this Agreement becomes effective or is terminated or the sale of the Notes to the Initial Purchasers is consummated, pay all fees, expenses, costs and charges in connection with: (i) the preparation, printing, filing, delivery and shipping of the Preliminary Offering Memorandum, the Disclosure Package, the Offering Memorandum and any amendments or supplements thereto; (ii) the printing, producing, copying and delivering the Transaction Agreements, the closing documents (including any compilations thereof) and any other agreements, memoranda, correspondence and other documents printed and delivered in
17 connection with the offering, purchase, sale and delivery of the Notes and with the Exempt Resales; (iii) the services of the Company’s independent registered public accounting firm; (iv) the services of the Company’s counsel; (v) the qualification of the Notes under the securities laws of the several jurisdictions as provided in Section 7(j) hereof and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel to the Initial Purchasers); (vi) any rating of the Notes by rating agencies; (vii) the services of the Trustee and any agent of the Trustee (including the fees and disbursements of counsel for the Trustee); (viii) any “roadshow” or other investor presentations relating to the offering of the Notes (including, without limitation, for meetings and travel); (ix) all expenses and application fees related to the listing of the Maximum Number of Underlying Common Stock on the Exchange and (x) otherwise incident to the performance of its obligations hereunder for which provision is not otherwise made in this Section 7(f). It is understood, however, that, except as provided in this Section 7(f) or Sections 8 and 9 hereof, the Initial Purchasers will pay all of their own costs and expenses, including the fees and expenses of counsel to the Initial Purchasers and any advertising expenses incurred in connection with the offering of the Notes. If the sale of the Notes provided for herein is not consummated by reason of acts of the Company or changes in circumstances of the Company pursuant to Section 8 of this Agreement which prevent this Agreement from becoming effective, or by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed or because any other condition of the Initial Purchasers’ obligations hereunder is not fulfilled or if the Initial Purchasers decline to purchase the Notes for any reason permitted under this Agreement, the Company will reimburse the Initial Purchasers for all reasonable out-of-pocket disbursements (including fees and expenses of counsel to the Initial Purchasers) incurred by the Initial Purchasers in connection with any investigation or preparation made by them in respect of the marketing of the Notes or in contemplation of the performance by them of their obligations hereunder. (g) Until completion of the distribution of the Notes, the Company will timely file all reports, documents and amendments to previously filed documents required to be filed by it pursuant to Section 12, 13(a), 13(c), 14 or 15(d) of the Exchange Act. (h) The Company will apply the net proceeds from the sale of the Notes as set forth in the Disclosure Package and the Offering Memorandum. (i) For a period commencing on the date hereof and ending on the 30th day after the date of the Offering Memorandum, the Company agrees not to, directly or indirectly, (i) offer for sale, sell, or otherwise dispose of (or enter into any transaction or device that is designed to, or would be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock (other than the shares of Common Stock issued pursuant to (i) employee benefit plans, qualified stock option plans, other employee compensation plans or non-employee director compensation programs (collectively, “Compensation Plans”) existing on the date hereof and disclosed in the Disclosure Package or pursuant to currently outstanding options, warrants or rights not issued under one of those plans or (ii) any existing forward sales contract), or sell or grant options, rights or warrants with respect to any shares of Common Stock or securities convertible into or
18 exchangeable for shares of Common Stock (other than the grant of options and other equity awards pursuant to Compensation Plans existing on the date hereof and disclosed in the Disclosure Package), (ii) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such shares of Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, (iii) file or cause to be filed a registration statement, including any amendments, with respect to the registration of Common Stock or securities convertible, exercisable or exchangeable into Common Stock (other than any registration statement on Form S-8), or (iv) publicly disclose the intention to do any of the foregoing, in each case without the prior written consent of the Representatives, and to cause each officer, director and stockholder of the Company set forth on Schedule V hereto to furnish to the Representatives, prior to the date of this Agreement, a letter or letters, substantially in the form of Exhibit A hereto (the “Lock-Up Agreements”). Notwithstanding the foregoing, the Company may sell shares of Common Stock pursuant to the Company’s existing at-the-market equity offering program under that certain Equity Distribution Agreement, dated May 2, 2025, by and between the Company and the Agents, Forward Purchasers, and Forward Sellers party thereto (as each such term is defined therein) (including entry into forward contracts not outstanding on the date hereof thereunder), provided that no such sales are effected or forward contracts entered into prior to the earlier of the 14th day after the date of the Offering Memorandum or the date on which the Initial Purchasers exercise their option to purchase the Additional Notes pursuant to Section 3 hereof. For the avoidance of doubt, the preceding sentence shall not prevent the delivery of shares of Common Stock pursuant to the settlement, or early termination, of any forward contract outstanding on the date hereof. For the further avoidance of doubt, nothing contained in this Section 7(i) shall prohibit or in any way restrict, or be deemed to prohibit or in any way restrict, the issuance of the Notes pursuant to this Agreement, the issuance of any Additional Notes or any shares of Underlying Common Stock that may be delivered upon conversion thereof, in each case, in accordance with the terms of the Indenture. (j) The Company will cooperate with the Initial Purchasers and with counsel to the Initial Purchasers in connection with the qualification of the Notes for offering and sale by the Initial Purchasers and by dealers under the securities laws of such jurisdictions as the Initial Purchasers may designate and will file such consents to service of process or other documents necessary or appropriate in order to effect such qualification and to permit the continuance of sales and dealings in such jurisdictions for as long as may be necessary to complete the distribution of the Notes; provided, however, that in no event will either the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action which would subject it to service of process in suits, other than for actions or proceedings arising out of the offering or sale of the Notes, in any jurisdiction where it is not now so subject. (k) The Company will not take, directly or indirectly, any action designed to cause or result in, or that might cause or result in, stabilization or manipulation of the price of the Notes to facilitate the sale or resale of the Notes.
19 (l) The Company will comply with all agreements set forth in the representation letters of the Company to DTC relating to the acceptance of the Notes for “book-entry” transfer through the facilities of DTC. (m) The Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to, resell any of the Notes that have been acquired by any of them, except for Notes purchased by the Company or any of its affiliates and resold in a transaction registered under the Securities Act. (n) The Company will not offer or sell any security that would be integrated with the sale of the Notes in a manner that would require the registration under the Securities Act of the sale to the Initial Purchasers or QIBs. (o) The Company will reserve and keep available at all times, free of pre-emptive rights, the Maximum Number of Underlying Common Stock for the purpose of enabling the Company to satisfy all obligations to issue any shares of Underlying Common Stock upon conversion of the Notes. The Company will use its best efforts to cause and maintain the listing of the Maximum Number of Underlying Common Stock on the Exchange. 8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless, each Initial Purchaser, each person, if any, who controls any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate, director, officer, employee and agent of any Initial Purchaser from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Disclosure Package, any Issuer Written Information that the Company has used or referred to in connection with the sale of the Notes or the Offering Memorandum or any amendment or supplement thereto (if the Company furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, with respect to the Preliminary Offering Memorandum, the Disclosure Package or any Issuer Written Information that the Company has used or referred to in connection with the sale of Notes or the Offering Memorandum or any amendment or supplement thereto (if the Company furnished any amendments or supplements thereto), not misleading in light of the circumstances under which they were made, except in each case insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use therein.
20 (b) Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company and their respective directors, principal executive officer or officers, principal financial officer, controller or principal accounting officer, and each person if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Initial Purchaser, but only with reference to 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, the Disclosure Package or any Issuer Written Information that the Company have used or referred to in connection with the sale of Notes or the Offering Memorandum or any amendment or supplement thereto. The Company acknowledges that the statements in the first paragraph under the caption “Plan of Distribution – New Issue of Notes” in the Preliminary Offering Memorandum and the Offering Memorandum regarding market making activities of the Initial Purchasers and the first and second paragraphs under the caption “Plan of Distribution – Price Stabilization and Short Positions” in the Preliminary Offering Memorandum and the Offering Memorandum, constitute the only written information furnished to the Company by the Representatives on behalf of the Initial Purchasers, referred to in Sections 2(j), 2(k), 8(a) and 8(b) of this Agreement. (c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel chosen by the indemnifying party and reasonably satisfactory to the indemnified party to represent the indemnified party and any others entitled to indemnification pursuant to this Section 8 the indemnifying party may designate in such proceeding and shall pay the reasonably incurred fees and expenses of such counsel related to such proceeding as incurred. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the reasonably incurred fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party within a reasonable time after notice of commencement of any such proceeding. It is understood and agreed that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such reasonably incurred fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representatives in the case of parties indemnified pursuant to Section 8(a), and by the Company, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, such consent shall not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, provided that such consent shall not be unreasonably withheld, effect any settlement of any pending or threatened proceeding in respect
21 of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include any statement as to, or an admission of, fault, culpability or failure to act by or on behalf of any indemnified party. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it 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 such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. (d) To the extent the indemnification provided for in Section 8(a) or Section 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Notes or (ii) if the allocation provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other hand in connection with the offering of the Notes 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 Notes and the total discounts and commissions received by the Initial Purchasers in connection therewith, bear to the aggregate offering price of the Notes. The relative fault of the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amounts of Notes they have purchased hereunder, and not joint. (e) The Company and the Initial Purchasers agree that it would not be just or equitable if contribution pursuant to this Section 8 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 Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal
22 or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Initial Purchaser shall 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 Notes 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 remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. (f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Initial Purchaser, any person controlling any Initial Purchaser or any affiliate, director, officer, employee or agent of any Initial Purchaser or by or on behalf of the Company and its respective officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Notes. 9. Defaulting Initial Purchasers. (a) If, on the Closing Date or the Option Closing Date, as the case may be, any Initial Purchaser defaults in its obligations to purchase the Notes that it has agreed to purchase under this Agreement, the remaining non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Notes by the non-defaulting Initial Purchasers or 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 Notes, 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 Notes on such terms. In the event that within the respective prescribed periods, the non-defaulting Initial Purchasers notify the Company that they have so arranged for the purchase of such Notes, or the Company notifies the non-defaulting Initial Purchasers that it has so arranged for the purchase of such Notes, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date or the Option Closing Date, as the case may be, for up to seven 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 Disclosure Package, the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Disclosure Package or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser,” unless the context requires otherwise, includes any party not listed in Schedule I hereto that, pursuant to this Section 9, purchases Notes that a defaulting Initial Purchaser agreed but failed to purchase. (b) If, after giving effect to any arrangements for the purchase of the Notes 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 principal amount of such Notes that remain unpurchased on the Closing Date or the Option Closing Date, as the case may be, does not
23 exceed one-eleventh of the aggregate principal amount of all the Notes to be purchased on such date, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Notes that such Initial Purchaser agreed to purchase hereunder on such date plus such Initial Purchaser’s pro rata share (based on the principal amount of Notes that such Initial Purchaser agreed to purchase hereunder on such date) of the Notes of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made; provided that the non-defaulting Initial Purchasers shall not be obligated to purchase more than 110% of the aggregate principal amount of Notes that it agreed to purchase on the Closing Date or the Option Closing Date, as the case may be, pursuant to the terms of Section 3. (c) If, after giving effect to any arrangements for the purchase of the Notes 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 principal amount of such Notes that remain unpurchased on the Closing Date or the Option Closing Date, as the case may be, exceeds one-eleventh of the aggregate principal amount of all the Notes 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 the Option Closing Date, the obligation of the Initial Purchasers to purchase Additional Notes on the Option 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 9 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 7 and except that the provisions of Section 8 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. 10.

The Securities will be convertible into cash, shares of common stock of the Company, no par value per share (the “Common Stock”) or a combination of cash and Common Stock, at the Company’s election. In consideration for the agreement by the Initial Purchasers to participate in the Offering and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date hereof and continuing to and including the date 30 days after the date of the final offering memorandum (the “Lock-Up Period”) relating to the Offering (the “Final Memorandum”), the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Common Stock of the Company, or any options or warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock of the Company, whether now owned or hereafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the Securities and Exchange Commission (collectively the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such shares. Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) sales of the Undersigned’s Shares held as of the date hereof through the Company’s 401(k) plan pursuant to portfolio balancing opportunities provided by the terms of such 401(k) plan or (iv) with the prior written consent of the Representatives on behalf of the Initial Purchasers. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. The undersigned now has, and, except as contemplated by clause (i), (ii), (iii) or (iv)
or above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. 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 except in compliance with the foregoing restrictions. The undersigned understands that the Company and the Initial Purchasers are relying upon this Lock-Up Agreement in proceeding toward consummation of the offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns. Very truly yours, ________________________________________ [Name of Director/Executive Officer]
