The Company also proposes to issue and sell to the Initial Purchasers not more than an additional $22,500,000 principal amount of its 1.25% Convertible Senior Notes due 2020 (the “Additional Securities”) if and to the extent that you, as the Representatives, shall have determined to exercise, on behalf of the Initial Purchasers, the right to purchase such Additional Securities granted to the Initial Purchasers in Section 0 hereof.

(k)During the period of one year after the Closing Date or the Option Closing Date, if later, the Company will not be, nor will it become, an open-end investment company, unit investment trust or face-amount certificate company that is or is required to be registered under Section 8 of the Investment Company Act.

(l)So long as any Securities are outstanding, the Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) at such time (or any person who has been an affiliate within the three months preceding such time) to, resell any of the Securities or the Underlying Securities issued upon conversion of the Securities that have been reacquired by any of them, unless such Securities or Underlying Securities have been registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act that results in such Securities or Underlying Securities, as the case may be, no longer being “restricted securities” under Rule 144.

(p)To apply the net proceeds from the sale of the Securities as described in the Time of Sale Information and the Final Memorandum under the heading “Use of Proceeds.”

The Company also agrees that, without the prior written consent of each of the Representatives on behalf of the Initial Purchasers, it will not, during the period ending 90 days after the date of the Final Memorandum (the “Restricted Period”), (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, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any other securities convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, 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 publicly announce the intention to do any of the foregoing.

For the avoidance of doubt, nothing in the preceding paragraph shall prevent the entry into and performance under or termination of the Capped Call Confirmations by the Company or any Capped Call Counterparty.

7.Offering of Securities; Restrictions on Transfer. (a) Each Initial Purchaser, severally and not jointly, represents and warrants that such Initial Purchaser is a qualified institutional buyer as defined in Rule 144A under the Securities Act (a “QIB”). Each Initial Purchaser, severally and not jointly, agrees with the Company that (i) it will not solicit offers for, or offer or sell, such Securities by any General Solicitation, other than a Permitted General Solicitation listed on

Schedule II hereto, or those made with the prior written consent of the Company, or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act, (ii) it will sell such Securities only to persons that it reasonably believes to be QIBs that in purchasing such Securities are deemed to have represented and agreed as provided in the Final Memorandum under the captions “Notice to Investors” and “Transfer Restrictions.”

(b)Each Initial Purchaser, severally and not jointly, represents, warrants, and agrees with respect to offers and sales outside the United States that:

(i)such Initial Purchaser understands that no action has been or will be taken in any jurisdiction by the Company that would permit a public offering of the Securities, or possession or distribution of the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum or any other offering or publicity material relating to the Securities, in any country or jurisdiction where action for that purpose is required; and

(ii)the Securities have not been registered under the Securities Act and may not be sold within the United States or to, or for the account or benefit of, U.S. persons except in accordance with 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 5(d), 5(e), 5(f), 5(k)(ii)(B), 5(k)(ii)(C) and 5(k)(ii)(D) of this Agreement, 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 agrees that the Initial Purchasers may provide copies of the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum and the Indenture to Xtract Research LLC (“Xtract”), following completion of the offering, for inclusion in an online research service sponsored by Xtract, access to which shall be restricted by Xtract to QIBs.

8.Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Initial Purchaser, its officers and directors, 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 of any Initial Purchaser within the meaning of Rule 405 under the Securities Act 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 Memorandum, the Time of Sale Memorandum, any Additional Written Offering Communication prepared by or on behalf of, used by, or referred to by the Company, any General Solicitation made by the Company, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), the Final Memorandum or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, except 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 you expressly for use therein.

(b)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 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 you expressly for use in the Preliminary Memorandum, the Time of Sale Memorandum, any Additional Written Offering Communication identified in Schedule II hereto under the caption “Permitted Additional Written Offering Communications”, road show, any Permitted General Solicitation set forth in Schedule II hereto, the Final Memorandum or any amendment or supplement thereto, it being understood and agreed upon that the only such information furnished by any Initial Purchaser consists of the following information in the Preliminary Memorandum and Time of Sale Memorandum furnished on behalf of each Initial Purchaser: (i) the names set forth in the table of Initial Purchasers in the list under the first paragraph of text under the caption “Plan of Distribution” and (ii) the information contained in the thirteenth paragraph under the caption “Plan of Distribution” related to price stabilization and short positions.

(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 reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have mutually agreed in writing 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 (iii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party or (iv) the indemnified party shall have reasonably concluded there may be legal defenses available to it that are different from or additional to those available to the indemnifying party. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, otherwise be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such 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, 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, effect any settlement of any pending or threatened proceeding in respect 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 (i) includes an unconditional release of such

indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include any statement as to or any admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d)To the extent the indemnification provided for in Section 8(a) or 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 Company on the one hand and the Initial Purchasers on the other hand from the offering of the Securities 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 Company on the one hand and of the Initial Purchasers 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 Company on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the total discounts and commissions received by the Initial Purchasers bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and of the Initial Purchasers 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 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. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Securities 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 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 price at which the Securities resold by it in the initial placement of such Securities were offered to investors 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 of any Initial Purchaser or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

9.Termination. The Initial Purchasers may terminate this Agreement by notice given by you to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over‑the‑counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Memorandum or the Final Memorandum.

10.Effectiveness; Defaulting Initial Purchasers. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, or the Option Closing Date, as the case may be, any one or more of the Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase is not more than one‑tenth of the aggregate principal amount of Securities to be purchased on such date, the other Initial Purchasers shall be obligated severally in the proportions that the principal amount of Firm Securities set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Firm Securities set forth opposite the names of all such non‑defaulting Initial Purchasers, or in such other proportions as you may specify, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that any Initial Purchaser has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 0 by an amount in excess of one‑ninth of such principal amount of Securities without the written consent of such Initial Purchaser. If, on the Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Firm Securities which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities with respect to which such default occurs is more than one‑tenth of the aggregate principal amount of Firm Securities to be purchased on such date, and arrangements satisfactory to you and the Company for the purchase of such Firm Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non‑defaulting Initial Purchaser or of the Company. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Time of Sale Memorandum, the Final Memorandum or in any other documents or arrangements may be effected. If, on the Option Closing Date, any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Additional Securities and the aggregate principal amount of Additional Securities with respect to

which such default occurs is more than one-tenth of the aggregate principal amount of Additional Securities to be purchased on the Option Closing Date, the non-defaulting Initial Purchasers shall have the option to (a) terminate their obligation hereunder to purchase the Additional Securities to be sold on the Option Closing Date or (b) purchase not less than the principal amount of Additional Securities that such non-defaulting Initial Purchasers would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

If this Agreement shall be terminated by the Initial Purchasers, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Initial Purchasers or such Initial Purchasers as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Initial Purchasers in connection with this Agreement or the offering contemplated hereunder.

11.Entire Agreement. (a) This Agreement represents the entire agreement between the Company and the Initial Purchasers with respect to the preparation of the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum, the conduct of the offering, and the purchase and sale of the Securities.

(b)The Company acknowledges that in connection with the offering of the Securities: (i) the Initial Purchasers have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Initial Purchasers owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement) if any, and (iii) the Initial Purchasers may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Initial Purchasers arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

12.Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

13.Applicable 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 internal laws of the State of New York.

14.Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

OPINION OF COUNSEL FOR THE COMPANY

The opinion of the counsel for the Company, to be delivered pursuant to Section 5(d) of the Purchase Agreement shall be to the effect that:

A.The Company has been duly incorporated, is validly existing as a corporation under the laws of the jurisdiction of its incorporation and has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Memorandum.

B.The Purchase Agreement has been duly authorized, executed and delivered by the Company.

C.The authorized capital stock of the Company conforms as to legal matters to the description thereof contained in each of the Time of Sale Memorandum and the Final Memorandum.

D.The Securities have been duly authorized by the Company and, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of the Purchase Agreement, will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights generally and equitable principles of general applicability (regardless of whether considered in a proceeding in equity or at law) and will be entitled to the benefits of the Indenture pursuant to which such Securities are to be issued and the issuance of the Securities will not be subject to any statutory preemptive rights or any preemptive or similar rights under the articles of incorporation or bylaws of the Company.

E.The Maximum Number of Underlying Securities have been duly authorized and reserved for issuance and, when issued and delivered by the Company upon conversion of the Securities in accordance with the terms of the Securities and the Indenture, will be validly issued, fully paid and non‑assessable, and the issuance of the Underlying Securities is not subject to any statutory preemptive rights or any preemptive or similar rights under the articles of incorporation or bylaws of the Company.

F.The Indenture has been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery thereof by the Trustee, will be a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights generally and equitable principles of general applicability (regardless of whether considered in a proceeding in law or at equity).

G.The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Purchase Agreement, the Indenture and the Securities will not violate or result in a breach of (i) any provision of the federal laws of the United States, the laws of the State of Indiana or the laws of the State of New York (except no opinion need be rendered with respect to federal or state securities or Blue Sky laws), or (ii) the articles of incorporation or bylaws of the Company.

A1-1

X.Xx consent, approval, authorization or order of, or qualification with, any federal or state governmental body or agency is required under the federal laws of the United States, the laws of the State of Indiana or the laws of the State of New York to be made or obtained by the Company in connection with the performance by the Company of its obligations under the Purchase Agreement, the Indenture or the Securities or the consummation by the Company of the transactions effected pursuant to the Purchase Agreement, except such as have been obtained or may be required by the federal or state securities or Blue Sky laws in connection with the offer and sale of the Securities and the Underlying Securities or the consummation of the transactions effected pursuant to the Capped Call Confirmation.

I.The Company is not, and after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Final Memorandum will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended, and the rules and regulations thereunder.

J.The statements in each of the Time of Sale Memorandum and the Final Memorandum under the caption “Description of Notes” and “Description of Capital Stock,” insofar as such statements purport to summarize matters of law, descriptions of statutes, rules or regulations, or summaries of legal matters, documents or legal proceedings, in each case fairly summarize in all material respects such matters, statutes, rules, regulations, documents or proceedings.

K.The statements in each of the Time of Sale Memorandum and the Final Memorandum under the caption “Certain Material Federal Tax Considerations,” insofar as such statements purport to summarize the United States federal tax laws referred to therein, are accurate and fairly summarize in all material respects the United States federal tax laws referred to therein.

L.(i) In the opinion of such counsel each document filed by the Company with the Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and expressly incorporated by reference in the Time of Sale Memorandum or Final Memorandum (except for the financial statements and financial schedules and other financial and statistical data included therein or omitted therefrom, as to which such counsel need not express any opinion), when such document was filed with the Commission, appeared on its face to comply as to form in all material respects with the requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder (in passing upon compliance as to the form of such documents, such counsel has assumed that the statements made or incorporated by reference therein are complete and correct), and (ii) nothing has come to the attention of such counsel that causes such counsel to believe that (A) the Time of Sale Memorandum (except for the financial statements and financial schedules and other financial and statistical data included or incorporated by reference therein or omitted therefrom, as to which such counsel need not express any belief) as of the date of the Purchase Agreement or as amended or supplemented, if applicable, or as of the date such opinion is delivered contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (B) the Final Memorandum (except for the financial statements and financial schedules and other financial and statistical data included or incorporated by reference therein or omitted therefrom, as to which such counsel need not express any belief) when issued contained, or as of the date such opinion is delivered contains, any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

A1-2

With respect to the matters referred to in the paragraph above, counsel may state that his or her opinions and beliefs are based upon his or her participation in the preparation of the Time of Sale Memorandum and the Final Memorandum (and any amendments or supplements thereto) and review and discussion of the contents thereof and review of the documents incorporated by reference therein, but are without independent check or verification except as specified.

M.Assuming (i) the accuracy of the representations and warranties of, and compliance thereby with the agreements of, the Company and the Initial Purchasers contained in the Purchase Agreement and (ii) the offer, sale and delivery of the Securities are completed in the manner contemplated by, and in accordance with, the Purchase Agreement, the Time of Sale Memorandum and the Final Memorandum, it is not necessary in connection with the offer, sale and delivery of the Securities to the Initial Purchasers under the Purchase Agreement or in connection with the initial resale of such Securities by the Initial Purchasers in accordance with the Purchase Agreement, the Time of Sale Memorandum and the Final Memorandum to register the Securities under the Securities Act of 1933 or to qualify the Indenture under the Trust Indenture Act of 1939, it being understood that no opinion is expressed as to any subsequent resale of any Security or as to any Underlying Security.

EXHIBIT A2

OPINION OF CORPORATE COUNSEL FOR THE COMPANY

The opinion of Xxxxx Xxxxxx, Corporate Counsel for the Company, to be delivered pursuant to Section 5(e) of the Purchase Agreement shall be to the effect that:

A.The Company is duly qualified to transact business and, to the extent such concept is applicable, is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing, to the extent such concept is applicable, would not have a material adverse effect on the Company and its subsidiaries, taken as a whole.

B.Each Material Subsidiary of the Company has been duly incorporated, is validly existing as a corporation in good standing (to the extent such concept is applicable) under the laws of the jurisdiction of its incorporation, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Memorandum and is duly qualified to transact business and is in good standing, to the extent such concept is applicable, in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing, to the extent such concept is applicable, would not have a material adverse effect on the Company and its subsidiaries, taken as a whole; all of the issued shares of capital stock of each subsidiary of the Company have been duly and validly authorized and issued, are fully paid and non-assessable, are owned directly or indirectly by the Company (except for any director qualifying shares and other de minimus amounts of outstanding securities or ownership interests) and, to such counsel’s knowledge, are free and clear of all liens, encumbrances, equities or claims.

X.Xx such counsel’s knowledge, the execution and delivery by the Company of, and the performance by the Company of its obligations under, the Purchase Agreement, the Indenture and the Securities will not violate or result in a breach of any agreement or other instrument binding upon the Company or any of its subsidiaries the result of which would have a material adverse effect on the Company and its subsidiaries, taken as a whole, or any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Company or any subsidiary.

X.Xx such counsel’s knowledge after due inquiry, there are no legal or governmental proceedings pending or overtly threatened in writing to which the Company or any of its subsidiaries is a party or to which any of the properties of the Company or any of its subsidiaries is subject other than proceedings fairly summarized in all material respects in the Time of Sale Memorandum and proceedings which such counsel believes are not reasonably likely to have a material adverse effect on the Company and its subsidiaries, taken as a whole, or on the power or ability of the Company to perform its obligations under the Purchase Agreement, the Indenture or the Securities or to consummate the transactions effected pursuant to the Purchase Agreement.

Capped Call Transactions:

In connection with the pricing of the notes, we entered into capped call transactions with one or more of the initial purchasers or their affiliates. The capped call transactions are generally expected to reduce potential dilution to our common stock upon any conversion of notes and/or offset any cash payments we are required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap. If the initial purchasers exercise their over-allotment option, we may enter into additional capped call transactions.

Net Proceeds:

We estimate that the net proceeds from this offering will be approximately $145.1 million (or $167.0 million if the initial purchasers exercise their over-allotment option in full), after deducting the initial purchasers’ discount and estimated offering expenses payable by us.

Use of Proceeds:

We intend to use approximately $12.8 million of the net proceeds from this offering to pay the cost of the capped call transactions. See “Description of Capped Call Transactions” in the Preliminary Offering Memorandum.

We intend to use the remaining net proceeds from this offering for working capital and other general corporate purposes.

If the initial purchasers exercise their over-allotment option, we may use a portion of the net proceeds from the sale of the additional notes to enter into additional capped call transactions. Any remaining net proceeds from the sale of additional notes will be used for working capital and other general corporate purposes as described above. See “Use of Proceeds” in the Preliminary Offering Memorandum.

Description of Notes—Conversion Rights—Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change

Holders who convert their notes in connection with a make-whole fundamental change occurring prior to the maturity date of the notes may, under certain circumstances, be entitled to an increase in the conversion rate for the notes so surrendered for conversion, as described under the caption “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 for the notes will be increased per $1,000 principal amount of notes for each stock price and effective date set forth below:


	Stock Price
Effective Date	$45.36	$50.00	$55.00	$61.24	$70.00	$80.00	$100.00	$120.00	$150.00	$170.00	$200.00

The exact stock prices and effective dates may not be set forth in the table above, in which case:

If the stock price is between two stock prices in the table or the effective date is between two effective dates in the table, the number of additional shares by which the conversion rate will be increased will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day year.

If the stock price is greater than $200.00 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the conversion rate.

If the stock price is less than $45.36 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), no additional shares will be added to the conversion rate.

Notwithstanding the foregoing, in no event will the conversion rate per $1,000 principal amount of notes exceed 22.0458 shares of common stock, subject to adjustment in the same manner as the conversion rate as set forth in the Preliminary Offering Memorandum under the caption “Description of Notes—Conversion Rights—Conversion Rate Adjustments.”

Our obligation to increase the conversion rate for notes converted in connection with a make-whole fundamental change could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness and equitable remedies.
