may resell, subject to the conditions set forth herein, all or a portion of the Notes to purchasers (the “Subsequent Purchasers”) at any time after the date of this Agreement. 
 The Company has prepared an offering memorandum dated the date hereof setting forth information concerning the Company, the Notes, the Registration
Rights Agreement and the Common Stock in form and substance reasonably satisfactory to the Initial Purchasers. As used in this Agreement, “Offering Memorandum” means, collectively, the Preliminary Offering Memorandum dated March 5,

possess such valid and current licenses, certificates, authorizations or permits issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to conduct their respective businesses as currently conducted except where
the failure to possess any certificate, authorization or permit would not result in a Material Adverse Change, and neither the Company nor any subsidiary has received any notice of proceedings relating to the revocation or modification of, or
non-compliance with, any such certificate, authorization or permit which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, could have a Material Adverse Effect. 
 (y) Title to Properties. The Company and each of its subsidiaries has valid title to all the properties and assets reflected as owned in the
financial statements included in the Disclosure Package and the Final Offering Memorandum, in each case free and clear of any security interests, mortgages, liens, encumbrances, equities, claims and other defects, except such as do not, individually

property, improvements, equipment and personal property held under lease by the Company or any subsidiary are held under valid and enforceable leases, with such exceptions as are not material and do not, singly or in the aggregate, materially
interfere with the use made or proposed to be made of such real property, improvements, equipment or personal property by the Company or such subsidiary. 
 (z) Tax Law Compliance. The Company and its subsidiaries have filed all material federal, state, local and foreign income and franchise tax returns required to be filed in a timely manner, unless the Company
has otherwise filed an extension therefor and other than where such failure to so timely file would not result in a Material Adverse Effect, and have paid all taxes required to be paid by any of them and, if due and payable, any related or similar
assessment, fine or penalty levied against any of them, except for any taxes, assessments, fines or penalties as are being contested in good faith and by appropriate proceedings or the failure to pay which would not result in a Material Adverse
Effect. The Company has made appropriate provisions in the financial statements included in the Disclosure Package and the Final Offering Memorandum in respect of all federal, state and foreign income and franchise taxes for all current or prior
periods as to which the tax liability of the Company or any of its subsidiaries has not been finally determined.

 (aa) Company Not an “Investment Company”. The Company has been advised of the rules and
requirements under the Investment Company Act of 1940, as amended (the “Investment Company Act”). The Company is not, and, after receipt of payment for the Notes and application of the proceeds as described under “Use of
Proceeds” in the Disclosure Package and the Final Offering Memorandum, will not be, required to register as an “investment company” within the meaning of the Investment Company Act. 
 (bb) Compliance with Reporting Requirements. The Company is subject to and in compliance in all material respects with the reporting requirements
of Section 13 or Section 15(d) of the Exchange Act. 
 (cc) Insurance. Each of the Company and its subsidiaries are insured
by institutions that the Company reasonably believes are recognized, financially sound and reputable, with policies in such amounts and with such deductibles and covering such risks as are generally deemed reasonable and customary for their
businesses including, but not limited to, policies covering real and personal property owned or leased by the Company and its subsidiaries against theft, damage, destruction, acts of terrorism or vandalism and earthquakes. To the Company’s
knowledge, all policies of insurance insuring the Company or any of its subsidiaries or their respective businesses, assets, employees, officers and directors are in full force and effect; the Company and its subsidiaries are in compliance with the
terms of such policies and instruments in all material respects. The Company has no reason to believe that it or any subsidiary will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to
obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not have a Material Adverse Effect. 
 (dd) No Restriction on Distributions. No subsidiary of the Company is currently prohibited, directly or indirectly, from paying any dividends to
the Company, from making any other distribution on such subsidiary’s capital stock, from repaying to the Company any loans or advances to such subsidiary from the Company or from transferring any of such subsidiary’s property or assets to
the Company or any other subsidiary of the Company, except as described in or contemplated by the Disclosure Package and the Final Offering Memorandum. 
 (ee) No Price Stabilization or Manipulation. The Company has not taken and will not take, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization
or manipulation of the price of the Notes or the Conversion Shares to facilitate the sale or resale of the Notes. The Company acknowledges that the Initial Purchasers may engage in passive market making transactions in the Common Stock on the New
York Stock Exchange in accordance with Regulation M under the Exchange Act. 
 (ff) Related Party Transactions. There are no business
relationships or related-party transactions involving the Company or any subsidiary or any other person required to be described in the Disclosure Package and the Final Offering Memorandum which have not been described as required. 
 (gg) No General Solicitation. None of the Company or any of its affiliates (as defined in Rule 501(b) of Regulation D under the Securities Act
(“Regulation D”)) (“Affiliates”), has, directly or through an agent, engaged in any form of general solicitation or general advertising (as those terms are used in Regulation D) in connection with the offering of the Notes or the

  

 9 

 
Conversion Shares under the Securities Act or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act; the Company
has not entered into any contractual arrangement with respect to the distribution of the Notes or the Conversion Shares except for this Agreement, and the Company will not enter into any such arrangement except for the Indenture and the Registration
Rights Agreement and as may be contemplated hereby or thereby. 
 (hh) No Unlawful Contributions or Other Payments. Neither the
Company nor any of its subsidiaries nor, to the knowledge of senior management of the Company, any director, officer, agent, employee or affiliate of the Company or any of its subsidiaries is aware of any action, directly or indirectly, that has
resulted in a violation by such persons of the FCPA, including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the
payment of any money, or other offer, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any
candidate for foreign political office, in contravention of the FCPA. 
 “FCPA” means Foreign Corrupt Practices Act of 1977, as
amended, and the rules and regulations thereunder. 
 (ii) No Conflict with Money Laundering Laws. Neither the Company nor any of its
subsidiaries has conducted its business in a manner that has resulted in a failure to comply with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money
laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines issued, administered or enforced by any governmental agency. 
 (jj) No Conflict with OFAC Laws. Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any officer, agent or
employee of the Company or any of its subsidiaries is currently blocked by any U.S. sanctions by virtue of appearing on the Specifically Designated Nationals list of the Office of Foreign Assets Control of the U.S. Treasury Department
(“OFAC”) as of the date of this Agreement; and the Company will not directly or indirectly use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other
person or entity on OFAC’s Specifically Designated Nationals list for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC. 
 (kk) Compliance with Environmental Laws. Except as otherwise disclosed in the Disclosure Package and the Final Offering Memorandum
(i) neither the Company nor any of its subsidiaries is in violation of any federal, state, local or foreign law, regulation order, permit or other requirement relating to pollution or protection of human health or the environment (including,
without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including without limitation, laws and regulations relating to emissions, discharges, releases or threatened releases of chemicals,
pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum and petroleum products (collectively, “Materials of Environmental Concern”), or otherwise relating to the manufacture, processing, distribution, use,
treatment, storage, disposal, transport or handling of Materials of Environmental Concern (collectively, “Environmental Laws”), which violation includes, but is not limited to, noncompliance with any permits or other governmental
authorizations required for the operation of the business of the Company or its subsidiaries under applicable Environmental Laws, nor has 

  

 10 

 
the Company or any of its subsidiaries received any written communication, whether from a governmental authority, citizens group, employee or otherwise, that
alleges that the Company or any of its subsidiaries is in violation of any Environmental Law except as would not, individually or in the aggregate, have a Material Adverse Effect; (ii) there is no claim, action or cause of action filed with a
court or governmental authority, no investigation with respect to which the Company has received written notice, and no written notice by any person or entity alleging potential liability for investigatory costs, cleanup costs, governmental response
costs, natural resources damages, property damages, personal injuries, attorneys’ fees or penalties arising out of, based on or resulting from the presence, or release into the environment, of any Material of Environmental Concern at any
location owned, leased or operated by the Company or any of its subsidiaries, now or at the time of a release in the past (collectively, “Environmental Claims”), pending or, to the Company’s knowledge, threatened against the Company
or any of its subsidiaries or any person or entity whose liability for any Environmental Claim the Company or any of its subsidiaries has retained or assumed either contractually or by operation of law except as would not, individually or in the
aggregate, have a Material Adverse Effect; (iii) to the Company’s knowledge, there are no past, present or anticipated future actions, activities, circumstances, conditions, events or incidents, including, without limitation, the release,
emission, discharge, presence or disposal of any Material of Environmental Concern, that reasonably could result in a violation of any Environmental Law, required expenditures to be incurred pursuant to Environmental Law or form the basis of a
potential Environmental Claim against the Company or any of its subsidiaries or against any person or entity whose liability for any Environmental Claim the Company or any of its subsidiaries has retained or assumed either contractually or by
operation of law except as would not, individually or in the aggregate, have a Material Adverse Effect; and (iv) neither the Company nor any of its subsidiaries is subject to any pending or, to the Company’s knowledge, threatened
proceeding under Environmental Law to which a governmental authority is a party and which is reasonably likely to result in monetary sanctions of $100,000 or more. 
 (ll) Periodic Review of Costs of Environmental Compliance. In the ordinary course of its business, the Company conducts a periodic review of the effect of Environmental Laws on the business, operations and
properties of the Company and its subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or
compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review and the amount of its established reserves, the
Company has reasonably concluded that such associated costs and liabilities would not, individually or in the aggregate, have a Material Adverse Effect. 
 (mm) ERISA Compliance. The Company and its subsidiaries and any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and
published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, its subsidiaries or their “ERISA Affiliates” (as defined below) are in compliance with ERISA except where the failure to be
in compliance would not result in a Material Adverse Change. “ERISA Affiliate” means, with respect to the Company or a subsidiary, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the
Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company or such subsidiary is a member. Within the last five years, there has been no “reportable
event” as that term is defined in Section 4043 of ERISA and the regulations thereunder with respect to any of the “employee benefit plans” subject to Title IV of ERISA which would require the giving of notice under
Section 4043 of ERISA (disregarding any events for which the notice has been waived under Section 4043 of 

  

 11 

 
ERISA and the regulations thereunder). No “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA
Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA) except where such unfunded benefit liabilities would not result in a Material Adverse
Change. Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee
benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code, in each case except where such liabilities would not reasonably be expected to result in a Material Adverse Change. Each “employee benefit plan”
established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter from the Internal Revenue Service and,
since the date of such determination letter, to the Company’s knowledge, nothing has occurred, whether by action or failure to act, which would reasonably be expected to cause the loss of such qualification. Except as disclosed in the Final
Offering Memorandum, neither of the following events has occurred or is reasonably likely to occur: (i) a material increase in the aggregate amount of contributions required to be made to all Plans in the current fiscal year of the Company
compared to the amount of such contributions made in the Company’s most recently completed fiscal year; or (ii) a material increase in the Company’s “accumulated post-retirement benefit obligations” (within the meaning of
Statement of Financial Accounting Standards 106) compared to the amount of such obligations in the Company’s most recently completed fiscal year. For purposes of this paragraph, the term “Plan” means a plan (within the meaning of
Section 3(3) of ERISA) subject to Title IV of ERISA with respect to which any member of the Company may have any liability. 
 (nn)
Brokers. There is no broker, finder or other party that is entitled to receive from the Company any brokerage or finder’s fee or other fee or commission as a result of any transactions contemplated by this Agreement. 
 (oo) No Outstanding Loans or Other Indebtedness. There are no outstanding loans, advances (except normal advances for business expenses in the
ordinary course of business) or guarantees of indebtedness by the Company to or for the benefit of any of the officers or directors of the Company or any of the members of any of their families. 
 (pp) Sarbanes-Oxley Compliance. There is and has been no failure on the part of the Company and, to the knowledge of the Company, any of the
Company’s directors or officers, in their capacities as such, to comply with any provision of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the “Sarbanes-Oxley Act”), including
Section 402 related to loans and Sections 302 and 906 related to certifications. 
 (qq) Internal Controls and Procedures. The
Company maintains (i) effective internal control over financial reporting as defined in Rule 15d-15 under the Exchange Act and (ii) a system of internal accounting controls sufficient to provide reasonable assurance that
(A) transactions are executed in accordance with management’s general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted
accounting principles and to maintain asset accountability; (C) access to assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with the
existing assets at reasonable intervals and appropriate action is taken with respect to any differences. 
  

 12 

 (rr) No Material Weakness or Change in Internal Controls. Except as disclosed in the Disclosure
Package and the Final Offering Memorandum, since the end of the Company’s most recent audited fiscal year, there has been (i) no material weakness in the Company’s internal control over financial reporting (whether or not remediated)
and (ii) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. 
 (ss) Significant Subsidiaries. The subsidiaries listed on Annex A attached hereto are the only significant subsidiaries of the Company as defined
by Rule 1-02 of Regulation S-X (the “Significant Subsidiaries”). 
 (tt) Lending Relationship. Except as disclosed in
the Disclosure Package and the Final Offering Memorandum, the Company (i) does not have any material lending or other relationship with any bank or lending affiliate of any Initial Purchaser and (ii) does not intend to use any of the
proceeds from the sale of the Notes hereunder to repay any outstanding debt owed to any Affiliate of any Initial Purchaser. 
 (uu)
PORTAL. The Company has been advised by the NASD’s PORTAL Market that the Notes have been designated PORTAL-eligible securities in accordance with the rules and regulations of the NASD. 
 Any certificate signed by an officer of the Company and delivered to the Representative or to counsel for the Initial Purchasers at the closing shall be
deemed to be a representation and warranty by the Company to each Initial Purchaser as to the matters set forth therein. 
 Section 2. Purchase, Sale and Delivery of the Notes. 
 (a) The Firm Notes. The Company agrees to issue and sell
to the several Initial Purchasers the Firm Notes upon the terms herein set forth. On the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Initial
Purchasers agree, severally and not jointly, to purchase from the Company the respective principal amount of Firm Notes set forth opposite their names on Schedule A at a purchase price of 97.000% of the aggregate principal amount
thereof. 
 (b) The Closing Date. Delivery of the Firm Notes to be purchased by the Initial Purchasers and payment therefor shall be
made at the offices of Shearman & Sterling LLP, 599 Lexington Avenue, New York, New York 10022 (or such other place as may be agreed to by the Company and the Representative) at 9:00 a.m. New York time, on March 12, 2007, or such
other time and date as the Representative and the Company shall agree (the time and date of such closing are called the “Closing Date”). 
 (c) The Optional Notes; any Subsequent Closing Date. In addition, on the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Company hereby
grants an option to the several Initial Purchasers to purchase, severally and not jointly, up to $15,000,000 aggregate principal amount of Optional Notes from the Company at the same price as the purchase price to be paid by the Initial Purchasers
for the Firm Notes. The option granted hereunder may be exercised at any time and from time to time within the 13 day period beginning on the Closing Date upon notice by the Representative to the Company, which notice may be given at any time at
least two days prior to the Closing Date or Subsequent Closing Date (as defined below), as applicable. Such notice shall 
  

 13 

 
set forth (i) the amount (which shall be an integral multiple of $1,000 in aggregate principal amount) of Optional Notes as to which the Initial
Purchasers are exercising the option, (ii) the names and denominations in which the Optional Notes are to be registered and (iii) the time, date and place at which such Notes will be delivered (which time and date may be simultaneous with,
but not earlier than, the Closing Date; and in such case the term “Closing Date” shall refer to the time and date of delivery of the Firm Notes and the Optional Notes). Such time and date of delivery, if subsequent to the Closing Date, is
called a “Subsequent Closing Date” and shall be determined by the Representative. Such date may be the same as the Closing Date but not earlier than the Closing Date nor later than 10 business days after the date of such notice. If any
Optional Notes are to be purchased, each Initial Purchaser agrees, severally and not jointly, to purchase the principal amount of Optional Notes (subject to such adjustments to eliminate fractional amounts as the Representative may determine) that
bears the same proportion to the total principal amount of Optional Notes to be purchased as the principal amount of Firm Notes set forth on Schedule A opposite the name of such Initial Purchaser bears to the total principal amount of
Firm Notes. 
 (d) Payment for the Notes. Payment for the Notes shall be made at the Closing Date (and, if applicable, at any
Subsequent Closing Date) by wire transfer of immediately available funds to the order of the Company. 
 It is understood that the
Representative has been authorized, for its own account and the accounts of the several Initial Purchasers, to accept delivery of and receipt for, and make payment of the purchase price for, the Firm Notes and any Optional Notes the Initial
Purchasers have agreed to purchase. BAS, individually and not as the Representative of the Initial Purchasers, may (but shall not be obligated to) make payment for any Notes to be purchased by any Initial Purchaser whose funds shall not have been
received by the Representative by the Closing Date or any Subsequent Closing Date, as the case may be, for the account of such Initial Purchaser, but any such payment shall not relieve such Initial Purchaser from any of its obligations under this
Agreement. 
 (e) Delivery of the Notes. The Company shall deliver, or cause to be delivered, to the Representative for the accounts
of the several Initial Purchasers the Firm Notes at the Closing Date, against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. The Company shall also deliver, or cause to be
delivered, to the Representative for the accounts of the several Initial Purchasers, the Optional Notes the Initial Purchasers have agreed to purchase at the Closing Date or any Subsequent Closing Date, as the case may be, against the irrevocable
release of a wire transfer of immediately available funds for the amount of the purchase price therefor. Delivery of the Notes shall be made through the facilities of The Depository Trust Company unless the Representative shall otherwise instruct.
Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Initial Purchasers. 
 Section 3. Covenants of the Company. 
 The Company covenants and agrees with each Initial
Purchaser as follows: 
 (a) Representatives’ Review of Proposed Amendments and Supplements. During such period beginning
on the date hereof and ending on the date of the completion of the resale of the Notes by the Initial Purchasers (as notified by the Initial Purchasers to the Company), prior to amending or supplementing the Disclosure Package or the Final Offering
Memorandum, the 

  

 14 

 
Company shall furnish to the Representative for review a copy of each such proposed amendment or supplement, and the Company shall not print, use or
distribute such proposed amendment or supplement to which the Representative reasonably objects. 
 (b) Amendments and Supplements to the
Offering Memorandum and Other Securities Act Matters. If, at any time prior to the completion of the resale of the Notes by the Initial Purchasers (as notified by the Initial Purchasers to the Company), any event shall occur or condition exist
as a result of which it is necessary to amend or supplement the Disclosure Package or the Final Offering Memorandum in order that any Supplemental Offering Materials, the Disclosure Package or the Final Offering Memorandum will not include an untrue
statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered to a purchaser, not misleading, or if in the opinion of the
Representative or counsel for the Initial Purchasers it is otherwise necessary to amend or supplement any Supplemental Offering Materials, the Disclosure Package or the Final Offering Memorandum to comply with law, the Company shall promptly notify
the Initial Purchasers and prepare, subject to Section 3(a) hereof, such amendment or supplement as may be necessary to correct such untrue statement or omission. 
 (c) Copies of Offering Memorandum. The Company agrees to furnish the Representative, without charge, until the earlier of six months after the date hereof or the completion of the resale of the Notes by the
Initial Purchasers (as notified by the Initial Purchasers to the Company) as many copies of the materials contained in the Disclosure Package and the Final Offering Memorandum and any amendments and supplements thereto (including any documents
incorporated or deemed incorporated by reference therein) as the Representative may reasonably request. 
 (d) Blue Sky Compliance.
The Company shall cooperate with the Representative and counsel for the Initial Purchasers, as the Initial Purchasers may reasonably request from time to time, to qualify or register the Notes for sale under (or obtain exemptions from the
application of) the state securities or blue sky laws of those jurisdictions designated by the Representative, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the
distribution of the Notes. The Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would
be subject to taxation as a foreign corporation. The Company will advise the Representative promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Notes for offering, sale or trading in any
jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its reasonable best efforts to obtain the
withdrawal thereof at the earliest possible moment. 
 (e) Rule 144A Information. For so long as any of the Notes are “restricted
securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Company shall provide to any holder of the Notes or to any prospective purchaser of the Notes designated by any holder, upon request of such holder or prospective
purchaser, information required to be provided by Rule 144A(d)(4) of the Securities Act if, at the time of such request, the Company is not subject to the reporting requirements under Section 13 or 15(d) of the Exchange Act. 
 (f) Compliance with Securities Law. During the period beginning on the date hereof and ending on the date of the completion of the resale of the
Notes, the Company will comply in all material respects with all applicable securities and other laws, rules and regulations, including, 
  

 15 

 
without limitation, the Sarbanes-Oxley Act, and use its reasonable best efforts to cause the Company’s directors and officers, in their capacities as
such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes Oxley Act. 
 (g)
Legends. Each of the Notes will bear, to the extent applicable, the legend contained in “Transfer Restrictions” in the Disclosure Package and the Final Offering Memorandum for the time period and upon the other terms stated therein.

 (h) No General Solicitation. Except following the effectiveness of the Registration Statement (as defined in the Registration
Rights Agreement), the Company will not, and will cause its subsidiaries not to, solicit any offer to buy or offer to sell the Notes by means of any form of general solicitation or general advertising (as those terms are used in Regulation D under
the Securities Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act. 
 (i) No
Integration. The Company will not, and will cause its subsidiaries not to, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any “security” (as defined in the Securities Act) in a transaction that could
be integrated with the sale of the Notes in a manner that would require the registration under the Securities Act of the Notes. 
 (j)
Information to Publishers. Until the effectiveness of the Registration Statement (as such term is defined in the Registration Rights Agreement), any information provided by the Company to publishers of publicly available databases about the
terms of the Notes shall include a statement that the Notes have not been registered under the Act and are subject to restrictions under Rule 144A of the Act. 
 (k) DTC. The Company will cooperate with the Representative and use its best efforts to permit the Notes to be eligible for clearance and settlement through The Depository Trust Company. 
 (l) Rule 144 Tolling. During the period of two years after the Closing Date or, if later, any Subsequent Closing Date, 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 which constitute “restricted securities” under Rule 144 that have been reacquired by any of them. 

(m) Use of Proceeds. The Company shall apply the net proceeds from the sale of the Notes sold by it in the manner described under the caption
“Use of Proceeds” in the Disclosure Package and the Final Offering Memorandum. 
 (n) Transfer Agent. The Company shall
engage and maintain, at its expense, a registrar and transfer agent for the Common Stock. 
 (o) Available Conversion Shares. The
Company will reserve and keep available at all times, free of pre-emptive rights, the full number of Conversion Shares. 
 (p) Conversion
Price. Between the date hereof and the Closing Date, the Company will not do or authorize any act or thing that would result in an adjustment of the conversion price. 
 (q) Company to Provide Interim Financial Statements and Other Information. Prior to the Closing Date, the Company will furnish the Initial Purchasers, if and as soon as they have been prepared by or are
available to the Company, a copy of any unaudited interim financial statements of the Company for any period subsequent to the period covered by the most recent financial statements included in the Disclosure Package and the Final Offering
Memorandum. 
  

 16 

 (r) Agreement Not to Offer or Sell Additional
Securities. During the period commencing on the date hereof and ending on the 75th day following the date of the
Final Offering Memorandum, the Company will not, without the prior written consent of BAS (which consent may be withheld at the sole discretion of BAS), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or
establish an open “put equivalent position” or liquidate or decrease a “call equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer (or enter into any transaction
which is designed to, or might reasonably be expected to, result in the disposition of), or announce the offering of, or file any registration statement under the Securities Act in respect of, any shares of Common Stock, options or warrants to
acquire shares of the Common Stock or securities exchangeable or exercisable for or convertible into shares of Common Stock (other than as contemplated by this Agreement with respect to the Notes or with respect to any existing stock plan of any
acquired company); provided, however, that the Company may issue shares of its Common Stock or options to purchase its Common Stock, or Common Stock upon exercise of options, pursuant to any stock option, stock bonus or other stock
plan or arrangement described in the Disclosure Package and the Final Offering Memorandum, or any existing stock plan of any acquired company. 
 (s) Future Reports to Stockholders. The Company shall furnish to its stockholders as soon as practicable after the end of each fiscal year an annual report (including a balance sheet and statements of income, stockholders’
equity and cash flows of the Company and its consolidated subsidiaries certified by independent public accountants) and, as soon as practicable after the end of each of the first three quarters of each fiscal year (beginning with the fiscal quarter
ending after the effective date of the Registration Statement), to make available to its stockholders consolidated summary financial information of the Company and its subsidiaries for such quarter in reasonable detail. 
 (t) Future Reports to the Representative. During the period of five years after the Closing
Date the Company will furnish to the Representative at 9 West 57th Street, New York, NY 10022 (i) as soon as
practicable after the end of each fiscal year, copies of the annual report of the Company containing the balance sheet of the Company as of the close of such fiscal year and statements of income, stockholders’ equity and cash flows for the year

 (v) No Manipulation of Price. The Company will not take, directly or indirectly, any action designed to cause or result in, or that has
constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise the stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Notes. 
  

 17 

 (w) Existing Lock-Up Agreements. The Company will enforce all existing agreements between the
Company and any of its security holders that prohibit the sale, transfer, assignment, pledge or hypothecation of any of the Company’s securities in connection with a public offering by the Company. In addition, the Company will direct the
transfer agent to place stop transfer restrictions upon any such securities of the Company that are bound by such existing “lock-up” agreements for the duration of the periods contemplated in such agreements.

 (a) it has not offered or sold, and will not offer or sell, any Notes within the United States or to, or for the account or benefit of, U.S. persons (x) as part of their distribution at any time or
(y) otherwise until one year after the later of the commencement of the offering and the date of closing of the offering except, to those it reasonably believes to be a QIB. 
 (b) in accordance with Rule 502(c) of Regulation D promulgated under the Securities Act, neither it nor any person acting on its behalf has made or will

described in the Final Offering Memorandum. 
  

 21 

 Section 7. Reimbursement of Initial Purchasers’ Expenses. 
 If this Agreement is terminated by the Representative pursuant to Section 5, Section 10 or Section 11, or if the sale to the Initial
Purchasers of the Notes on the Closing Date is not consummated because of any refusal, inability or failure on the part of the Company to perform any agreement herein or to comply with any provision hereof, the Company agrees to reimburse the
Representative and the other Initial Purchasers (or such Initial Purchasers as have terminated this Agreement with respect to themselves), severally, upon demand for all out-of-pocket expenses that shall have been reasonably incurred by the
Representative and the Initial Purchasers in connection with the proposed purchase and the offering and sale of the Notes, including but not limited to fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and
telephone charges; provided, however, that the Company shall not be obligated to reimburse the expenses of any Representative or other Initial Purchaser who is a defaulting Initial Purchaser in the context of a termination of this Agreement
pursuant to Section 10. In the case of a termination of this Agreement by the Representative pursuant to Section 10, the defaulting Initial Purchaser or Initial Purchasers agree to reimburse the Company for all reimbursements made by the
Company to the Representative and the other Initial Purchasers pursuant to this Section 7. 
 Section 8. Indemnification.

 (a) Indemnification of the Initial Purchasers by the Company. The Company agrees to indemnify and hold harmless each Initial
Purchaser, its directors, officers and employees and agents, and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as
incurred, to which such Initial Purchaser or such controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue
statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Final Offering Memorandum, the Final Term Sheet, any Issuer Written Information, any Supplemental Offering Materials, or any written
information used by or with the consent of the Company in connection with the offer or sale of the Notes (or any amendment or supplement to the foregoing), or the omission or alleged omission therefrom of a material fact, in each case, necessary in
order to make the statements therein, in the light of the circumstances under which they were made, not misleading and to reimburse each Initial Purchaser and each such controlling person for any and all reasonable expenses (including the reasonable
fees and disbursements of one counsel chosen by BAS) as such expenses are reasonably incurred by such Initial Purchaser, its officers, directors, employees, agents or such controlling person in connection with investigating, defending, settling,
compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to
the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Representative
expressly for use in the Preliminary Offering Memorandum, the Final Offering Memorandum, the Final Term Sheet, any Issuer Written Information, any Supplemental Offering Materials, or any written information used by or with the consent of the Company
in connection with the offer or sale of the Notes (or any amendment or supplement to the foregoing). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have. 

 

 22 

 (b) Indemnification of the Company, its Directors and Officers. Each Initial Purchaser agrees,
severally and not jointly, to indemnify and hold harmless the Company, each of its directors, each of its officers and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any loss,
claim, damage, liability or expense, as incurred, to which the Company, or any such director, officer or controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated
below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Final Offering Memorandum, the Final Term Sheet, any Issuer Written Information, any Supplemental
Offering Materials, or any written information used by or with the consent of the Company in connection with the offer or sale of the Notes (or any amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission
to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, and only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in the Preliminary Offering Memorandum, the Final Offering Memorandum, the Final Term Sheet, any Issuer Written Information, any Supplemental Offering Materials, or any written information
used by or with the consent of the Company in connection with the offer or sale of the Notes (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by or on behalf of the
Representative expressly for use therein; and to reimburse the Company, or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer or controlling person in
connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company hereby acknowledges that the only information that the Initial Purchasers have furnished to the
Company expressly for use in the Preliminary Offering Memorandum, the Final Offering Memorandum, the Final Term Sheet, any Issuer Written Information, any Supplemental Offering Materials, or any written information used by or with the consent of the
Company in connection with the offer or sale of the Notes (or any amendment or supplement thereto) are the statements set forth in Schedule C. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities
that each Initial Purchaser may otherwise have. 
 (c) Notifications and Other Indemnification Procedures. Promptly after receipt by
an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof may be made against an indemnifying party under this Section 8, notify the indemnifying party
in writing of the commencement thereof, but the failure to so notify the indemnifying party (i) will not relieve the indemnifying party from liability under paragraph (a) or (b) above unless and to the extent such indemnifying party
did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any
indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an
indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly
after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the
indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action
or that there may be legal defenses available to it 

  

 23 

 
and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall
have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified
party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or
other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being
understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), reasonably approved by the indemnifying party (or by BAS in the case of Section 8(b) and
Section 9), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable
time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party. 
 (d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there is a
final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. 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 Section 8(c) hereof, 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 90 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. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry
of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement,
compromise or consent (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of
fault, culpability or a failure to act by or on behalf of any indemnified party. 
 Section 9. Contribution. 
 If the indemnification provided for in Section 8 is for any reason unavailable to or otherwise insufficient to hold harmless an indemnified party in
respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims,
damages, liabilities or expenses referred to therein (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
Notes pursuant to this Agreement or (ii) if the allocation provided by clause (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 (i) above
but also the relative fault of the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses,
claims, damages, liabilities or 

  

 24 

 
expenses, 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 Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes pursuant to this Agreement (before deducting
expenses) received by the Company, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Notes. The relative fault of the Company, on the one hand, and the Initial Purchasers, on the other
hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate
representation or warranty relates to information supplied by the Company, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. 
 The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses
referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

 The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 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 which does not take account of the equitable considerations referred to in this Section 9.

 Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the
amount by which the total price at which the Notes purchased by such Initial Purchaser and distributed to investors were offered to investors exceeds the amount of any damages which 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 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in
Schedule A. For purposes of this Section 9, each officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities Act and the Exchange Act shall have the
same rights to contribution as such Initial Purchaser, and each director of the Company, each officer of the Company, and each person, if any, who controls the Company within the meaning of the Securities Act and the Exchange Act shall have the same
rights to contribution as the Company. 
 Section 10. Default of One or More of the Several Initial Purchasers. 
 If, on the Closing Date or any Subsequent Closing Date, as the case may be, any one or more of the several Initial Purchasers shall fail or refuse to
purchase Notes that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of
the aggregate principal amount of the Notes to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the principal amount of Firm Notes set forth opposite their respective names on
Schedule A bears to the aggregate principal amount of Firm Notes set forth opposite the names of all such non- 

  

 25 

 
defaulting Initial Purchasers, or in such other proportions as may be specified by the Representative with the consent of the non-defaulting Initial
Purchasers, to purchase the Notes which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on such date. If, on the Closing Date or any Subsequent Closing Date, as the case may be, any one or more of the
Initial Purchasers shall fail or refuse to purchase Notes and the aggregate principal amount of Notes with respect to which such default occurs exceeds 10% of the aggregate principal amount of Notes to be purchased on such date, and arrangements
satisfactory to the Representative and the Company for the purchase of such Notes are not made within 48 hours after such default, this Agreement shall terminate without liability of any party (other than a defaulting Initial Purchaser) to any other
party except that the provisions of Section 4, Section 7, Section 8 and Section 9 shall at all times be effective and shall survive such termination. In any such case either the Representative or the Company shall have the right to
postpone the Closing Date or any Subsequent Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Final Offering Memorandum or any other documents or arrangements may be
effected. 
 As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a
defaulting Initial Purchaser under this Section 10. Any action taken under this Section 10 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

 Section 11. Termination of this Agreement. 
 On or prior to the Closing Date this Agreement may be terminated by the Representative by notice given to the Company if at any time (i) trading or quotation in any of the Company’s securities shall have
been suspended or limited by the Commission or by the New York Stock Exchange, or trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices
shall have been generally established on any of such stock exchanges by the Commission or the NASD; (ii) a general banking moratorium shall have been declared by any federal, New York or Delaware authority or a material disruption in commercial
banking or securities settlement or clearance services in the United States has occurred; or (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the
United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the
Representative is material and adverse and makes it impracticable or inadvisable to market the Notes in the manner and on the terms described in the Disclosure Package and the Final Offering Memorandum or to enforce contracts for the sale of
securities. Any termination pursuant to this Section 11 shall be without liability on the part of (a) the Company to any Initial Purchaser, except to the extent that the Company is obligated to reimburse the expenses of the Representative
and the Initial Purchasers pursuant to Sections 4 and 7 hereof, or (b) any Initial Purchaser to the Company, provided, however, that if the Company reimbursed the Initial Purchasers for their expenses pursuant to Section 7
hereof and the defaulting Initial Purchaser or Initial Purchasers are obligated to reimburse the Company for all reimbursements made by the Company to the Representative and the other Initial Purchasers pursuant to Section 7 hereof, such
obligation to reimburse the Company shall survive. 
  

 26 

 Section 12. Representations and Indemnities to Survive Delivery. 
 The respective indemnities, contribution, agreements, representations, warranties and other statements of the Company and of the several Initial
Purchasers set forth in or made pursuant to this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation, or statement as to the result thereof, made by or on behalf of any Initial Purchaser or the
Company or any of its or their partners, officers or directors or any controlling person, as the case may be, (ii) acceptance of the Notes and payment for them hereunder or (iii) any termination of this Agreement.

 Section 14. Successors. 
 This Agreement will inure to the benefit of and be binding upon the parties hereto, including any substitute Initial Purchasers pursuant to Section 10 hereof, and to the benefit of the employees, officers and
directors and controlling persons referred to in Section 8 and Section 9, and in each case their respective successors, and no other person will have any right or obligation hereunder. The term “successors” shall not include any
purchaser of the Notes as such from any of the Initial Purchasers merely by reason of such purchase. 
 Section 15. Partial
Unenforceability. 
 The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the
validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes
(and only such minor changes) as are necessary to make it valid and enforceable. 
 Section 16. Governing Law Provisions.

 This Agreement shall be governed by and construed in accordance with the laws of the State of New York. 
 Section 17. No Advisory or Fiduciary Relationship. 
 The Company acknowledges and agrees that: (i) the purchase and sale of the Notes pursuant to this Agreement, including the determination of the offering price of the Notes and any related discounts and
commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Initial Purchasers, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the
terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a
principal and is not the agent or fiduciary of the Company, its affiliates, stockholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the
Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company on other matters) or any other obligation in
connection with the transactions contemplated by this Agreement to the Company except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of
transactions that involve interests that differ from those of the Company and that the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Initial
Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

 This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the several Initial
Purchasers, or any of them, 

  

 28 

 
with respect to the subject matter hereof. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may
have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty. 
 Section 18. General
Provisions. 
 No indemnified party shall be entitled to any consequential, special or punitive damages by virtue of Section 8 or 9
of this Agreement except to the extent that such indemnified party is obligated to pay such types of damages to a third party in respect of a claim for which such indemnified party is entitled to indemnification or contribution. This Agreement
constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be
executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the
parties hereto. The Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement. This Agreement is not intended to, and does not, create any rights, benefits, remedies
or claims of any person other than the parties hereto.

	 Issue price
	  	100%
		
	 Aggregate principal amount offered:
	  	$85 million (excluding option to purchase up to $15 million of additional notes)
		
	 Net proceeds:
	  	Approximately $81.90 million (or $96.45 million if the initial purchasers exercise their option to purchase $15 million of additional notes in full) after deducting underwriting discount and
offering expenses

	 U.S. Federal Income Tax Considerations :
	  	For U.S. federal income tax purposes, interest income on the notes will accrue at the rate of 8.375% compounded semi-annually, which rate represents our determination of the yield at which we
could issue a comparable noncontingent, nonconvertible, fixed-rate debt instrument with terms and conditions otherwise similar to the notes. A U.S. holder will be required to accrue interest income on a constant yield to maturity basis at this rate
(subject to certain adjustments), with the result that a U.S. holder may recognize interest income significantly in excess of stated interest payments received while the notes are outstanding.
		
	Adjustment to conversion rate upon a Public Acquirer Change of Control:	  	The following table sets forth the hypothetical stock price, effective date and number of additional shares to be issuable per $1,000 principal amount of notes:

 Form of Comfort Letter 
 March 6, 2007 
 Barnes Group Inc. and its Board of Directors 
 and 
 Banc of America Securities LLC 
 as representatives of the several initial purchasers 
 c/o Banc of America Securities LLC 
 9 West 57th Street 
 New York, NY 10019 
 Ladies and Gentlemen: 
 We have audited: 
  

	 	1.	the consolidated financial statements of Barnes Group Inc. (the “Company”) and its subsidiaries as of December 31, 2006 and 2005 and for each of the three years in
the period ended December 31, 2006 included in the Company’s annual report on Form 10-K for the year ended December 31, 2006 (the “Form 10-K”), 

  

	 	2.	the related financial statement schedule included in the Form 10-K, 

  

	 	3.	management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006 which is included in the Form 10-K,
and 

  

	 	4.	the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006. 

 The consolidated financial statements, financial statement schedule, and management’s assessment referred to above are all incorporated by reference
in the offering memorandum for up to $100,000,000 Convertible Senior Subordinated Notes due 2027 (the “Notes”); our reports with respect thereto including our opinion regarding the effectiveness of the Company’s internal control over
financial reporting (which contains an explanatory paragraph on management’s assessment of the effectiveness of internal control over financial reporting and on the effectiveness of internal control over financial reporting due to the exclusion
of Heinz Hänggi AG, Stanztechnik (Heinz Hänggi) and the KENT Division of Premier Farnell (KENT) because they were acquired by the Company in purchase business combinations during 2006) are also incorporated by reference in the offering
memorandum. The preliminary offering memorandum dated March 5, 2007 is herein referred to as the “Offering Memorandum”. 
  

 Exh. A-1 

 This letter is being furnished in reliance upon your representation to us that: 
  

	a.	You are knowledgeable with respect to the due diligence review process that would be performed if this placement of securities were registered pursuant to the Securities Act of 1933
(the “Act”). 

  

	b.	In connection with the offering of Notes, the review process you have performed is substantially consistent with the due diligence review process that you would have performed if
this placement of Notes were being registered pursuant to the Act. 

 In connection with the Offering Memorandum: 
  

	1.	We are an independent registered public accounting firm with respect to the Company within the applicable rules and regulations adopted by the Securities and Exchange Commission
(“SEC”) and the Public Company Accounting Oversight Board (United States) (“PCAOB”). 

  

	2.	Company officials have advised us that the consolidated financial statements and related financial statement schedule incorporated by reference in the Offering Memorandum are
prepared in accordance with Regulation S-X of the SEC. In our opinion, the consolidated financial statements and related financial statement schedule audited by us and incorporated by reference in the Offering Memorandum comply as to form in all
material respects with the applicable sections of Regulation S-X. 

  

	3.	We have not audited any financial statements of the Company as of any date or for any period subsequent to December 31, 2006. Therefore, we are unable to and do not express any
opinion on the financial position, results of operations or cash flows as of any date or for any period subsequent to December 31, 2006. Also, we have not audited the Company’s internal control over financial reporting as of any date
subsequent to December 31, 2006. Therefore, we do not express any opinion on the Company’s internal control over financial reporting as of any date subsequent to December 31, 2006.  

  

	4.	For purposes of this letter, we have read the minutes of the Board of Directors, Audit Committee, Corporate Governance Committee, Finance Committee and Compensation and Management
Development Committee of the Company and its subsidiaries as set forth in the minute books at March 5, 2007, officials of the Company having advised us that the minutes of all such meetings through that date were set forth therein (except for
the minutes of Board of Directors meeting held on February 14, 2007, Audit Committee meetings held on February 15, 2007 and February 20, 2007, Corporate Governance Committee meeting held on February 14, 2007, Finance Committee
meeting held on October 18, 2006 and Compensation and Management Development Committee meeting held on February 14, 2007 which were not approved in final form, for which drafts were provided to us; officials of the Company have represented
that such drafts include all substantive actions taken at such meeting), and have carried out other procedures to March 5, 2007 (our work did not extend to March 6, 2007 inclusive) as follows: 

  

 Exh. A-2 

	 	a.	With respect to the period from January 1, 2007 to January 31, 2007, we have: 

  

	 	(i)	read the unaudited consolidated financial data of the Company and subsidiaries for January of both 2007 and 2006 furnished us by the Company, officials of the Company having advised
us that no such financial data as of any date or for any period subsequent to January 31, 2007 were available. The financial information for January 2007 and 2006 is incomplete in that it omits the statement of cash flows and other disclosures.

  

	 	(ii)	inquired of certain officials of the Company who have responsibility for financial and accounting matters as to whether the unaudited consolidated financial data referred to in a(i)
above are stated on a basis substantially consistent with that of the audited consolidated financial statements incorporated by reference in the Offering Memorandum. 

 The foregoing procedures do not constitute an audit made in accordance with standards of the PCAOB. Also, they would not necessarily reveal matters of
significance with respect to the comments in the following paragraph. Accordingly, we make no representations as to the sufficiency of the foregoing procedures for your purposes. 
  

	5.	It should be noted effective January 1, 2007, the Company adopted FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes (an
interpretation of FASB Statement No. 109).” Nothing came to our attention as a result of the foregoing procedures, however, that caused us to believe that: 

 (i) At January 31, 2007 there was any change in the capital stock, increase in long-term debt, or decrease in consolidated net current assets
(working capital) or stockholders’ equity of the Company and subsidiaries consolidated as compared with amounts shown in the December 31, 2006 consolidated balance sheet incorporated by reference in the Offering Memorandum, or
(ii) for the period from January 1, 2007 to January 31, 2007, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated net sales, income before income taxes or in the total or
per-share amounts of net income, except in all instances for changes, increases or decreases which the Offering Memorandum discloses have occurred or may occur, and except that the unaudited consolidated financial data as of January 31, 2007,
which we were furnished by the Company, showed the following: 
 [CHART SHOWING CHANGES/DECREASES TO BE INSERTED] 
  

	6.	 It should be noted effective January 1, 2007, the Company adopted FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in
Income Taxes (an interpretation of FASB Statement No. 109).” As mentioned in 4a, Company officials have advised us that no consolidated financial data as of any date or for any period subsequent to January 31, 2007 are available;
accordingly, the procedures carried out by us with respect to changes in financial statement items 

  

 Exh. A-3 

	 	 
after January 31, 2007 have, of necessity, been even more limited than those with respect to the periods referred to in 4. We have inquired of certain
officials of the Company who have responsibility for financial and accounting matters as to whether (a) at March 5, 2007 there was any change in the capital stock, increase in long-term debt, or decrease in consolidated net current assets
(working capital) or stockholders’ equity of the Company and subsidiaries consolidated as compared with amounts shown in the December 31, 2006 consolidated balance sheet incorporated by reference in the Offering Memorandum; or (b) for
the period from February 1, 2007 to March 5, 2007, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated net sales, income before taxes or in the total or per-share amounts of net
income. Those officials referred to above stated that they cannot comment on any such changes, increases or decreases in consolidated net sales, income before taxes or the total or per-share amounts of net income for the periods referred to above.
On the basis of these inquiries and our reading of the minutes as described in 4, nothing came to our attention that caused us to believe that there was any such change in the capital stock, increase in long-term debt or decrease in consolidated net
current assets (working capital) or stockholders’ equity, except in all instances for changes, increases or decreases which the Offering Memorandum discloses have occurred or may occur. 

  

	7.	For purposes of this letter, we have also read the items identified by you on the attached copy of the Offering Memorandum and have performed the following procedures, which were
applied as indicated with respect to the letters explained below. We make no comment as to whether the SEC would view any non-GAAP financial information included or incorporated by reference in the Offering Memorandum as being compliant with the
requirements of Regulation G or Item 10 of Regulation S-K. 

  

			
	A	  	 Compared with, or recomputed from, a corresponding amount included in the Company’s accounting records and found such amounts to be in
agreement.

		
	B	  	 Recomputed from the actual column for the proposed use of proceeds of the Notes to be offered by means of this Offering Memorandum as described under “Use
of Proceeds.” However, we make no comment as to whether the sale of the Notes will be consummated and the use of proceeds as described therein will actually occur.

		
	C	  	 Compared to a schedule prepared by the Company from its accounting records and found such amounts to be in agreement. We (a) compared the amounts on the
schedule to corresponding amounts appearing in the accounting records and found such amounts to be in agreement and (b) determined that the schedule was mathematically correct. However, we make no comment regarding the statement that one third of
rental expense is a reasonable estimate of interest factor related to such rental expense. Furthermore, we make no comment regarding the Company’s estimation of amortization of capitalized interest.

  

 Exh. A-4 

			
	D	  	 Compared to a schedule prepared by the Company from its accounting records and found such amounts to be in agreement. We (a) compared the amounts on the
schedule to corresponding amounts appearing in the accounting records and found such amounts to be in agreement and (b) determined that the schedule was mathematically correct. It should be noted that EBITDA and the percentage change in the
Company’s international sales excluding the impact of foreign currency translation are not measures of operating performance or liquidity defined by generally accepted accounting principles and may not be comparable to similarly titled measures
presented by other companies. We make no comment about the Company’s definition, calculation or presentation of EBITDA and the percentage change in the Company’s international sales excluding the impact of foreign currency translation or
their usefulness for any purposes.

		
	E	  	 Compared to or recomputed from a corresponding amount in the Company’s audited financial statements incorporated by reference in the Offering Memorandum
and found such amounts to be in agreement. We make no comment as to the appropriateness or completeness of the Company’s determination of the Regulation S-K requirements for quantitative and qualitative disclosures about market risks or as to
the reasonableness of the Company’s assumptions underlying such disclosures.

  

	8.	Our audit of the consolidated financial statements for the periods referred to in the introductory paragraph of this letter comprised audit tests and procedures deemed necessary for
the purpose of expressing an opinion on such financial statements taken as a whole. For none of the periods referred to therein, or any other period, did we perform audit tests for the purpose of expressing an opinion on individual balances of
accounts or summaries of selected transactions such as those enumerated above, and, accordingly, we express no opinion thereon. 

  

	9.	The procedures enumerated in paragraph 7 do not constitute an audit conducted in accordance with standards of the PCAOB. Accordingly, we make no representations regarding the
sufficiency of the foregoing procedures for your purposes. 

  

	10.	It should be understood that we make no representations regarding questions of legal interpretation or regarding the sufficiency for your purposes of the procedures enumerated in
the preceding paragraphs; also, such procedures would not necessarily reveal any material misstatement of the amounts or percentages listed above. Further, we have addressed ourselves solely to the foregoing data as set forth in the Offering
Memorandum and make no representations regarding the adequacy of disclosure or regarding whether any material facts have been omitted. 

  

 Exh. A-5 

	11.	This letter is solely for the information of the addressees and to assist the underwriters in conducting and documenting their investigation of the affairs of the Company in
connection with the offering of the Notes covered by the Offering Memorandum, and is not to be used, circulated, quoted, or otherwise referred to within or without the underwriting group for any other purpose, including but not limited to the
purchase or sale of the Notes, nor is it to be filed with or referred to in whole or in part in the Offering Memorandum or any other document, except that reference may be made to it in the Purchase Agreement or in any list of closing documents
pertaining to the offering of the Notes covered by the Offering Memorandum.

legal proceedings, or legal conclusions, have been reviewed by such counsel and fairly summarize, in all material respects, the matters referred to therein. 
  

 Exh. B-1-2 

 (xii) No consent, approval, authorization or other order of, or registration or filing
with, any court or other governmental authority or agency, is required for the Company’s execution, delivery and performance of the Purchase Agreement and consummation of the transactions contemplated thereby, by the Disclosure Package and by
the Final Offering Memorandum, except as required under the Securities Act, the Exchange Act, the Trust Indenture Act, applicable state securities or blue sky laws, or the rules of the New York Stock Exchange or the NASD.
