Ladies and Gentlemen:

RBC Bearings Incorporated, a Delaware corporation (the “Company”), and the persons listed in Schedule B hereto (collectively, the “Selling Shareholders”), confirm their respective agreements with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Merrill Lynch, KeyBanc Capital Markets and Jefferies & Company, Inc., are acting as representatives (in such capacity, the “Representatives”), with respect to (i) the issue and sale by the Company and the Selling Shareholders, acting severally and not jointly, and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of shares of Common Stock, $.01 par value per share, of the Company (“Common Stock”) set forth in Schedules A and B hereto, and (ii)  the grant by the Company and the Selling Shareholders to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 1,243,200 additional shares of Common Stock to cover over-allotments, if any.  The aforesaid 8,288,000 shares of Common Stock (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the 1,243,200 shares of Common Stock subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities.”

The Company and the Selling Shareholders understand that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (No. 333-124824), including the related preliminary prospectus or prospectuses, covering the registration of the Securities under the Securities Act of 1933, as amended (the “1933 Act”). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430A (“Rule 430A”) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”) and paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations.  The information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to paragraph (b) of Rule 430A is referred to as “Rule 430A Information.”  Each prospectus used before such registration statement became effective, and any prospectus that omitted the Rule 430A Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a “preliminary prospectus.”  Such registration statement, including the exhibits and any schedules thereto, at the time it became effective, and including the Rule 430A Information, is herein called the “Registration Statement.”  Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the “Rule 462(b) Registration Statement,” and after such filing the term “Registration Statement” shall include the Rule 462(b) Registration Statement.  The final prospectus in the form first furnished to the Underwriters for use in connection with the offering of the Securities is herein called the “Prospectus.”  For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”).

Prior to the consummation of the sale of the Securities, (1) the Company will amend and restate or certificate of incorporation to effect a 5-for-2 stock split of the Common Stock, (2) all outstanding shares of the Company’s Class B preferred stock will be converted in accordance with their terms into 1,846,396 (on a post stock split basis) shares of Class A common stock,   shares of Class C preferred stock and shares of Class D preferred stock, (3) all of the outstanding shares of the Company’s Class C Preferred Stock will be redeemed, (4) all of the outstanding shares of the Company’s Class D preferred stock will be repurchased, (5)  the Company’s certificate of incorporation will be amended and restated to effect the authorization of 60,000,000 shares of Common Stock (of which 15,458,833 will be outstanding), 10,000,000 shares of undesignated preferred stock (of which none will be outstanding),  and the reclassification into Common Stock of all other classes of common and preferred stock, as otherwise described in the Prospectus, and (6) all outstanding options and warrants will become exercisable into shares of Common Stock (collectively, in each case as more precisely described in the Prospectus, the “Pre-Offering Transactions”).

4

(vi)             Good Standing of Subsidiaries.  Each subsidiary of the Company (each a “Subsidiary” and, collectively, the “Subsidiaries”) has been duly organized and is validly existing as a corporation or limited liability company in good standing under the laws of the jurisdiction of its incorporation, has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus and is duly qualified as a foreign corporation or limited liability company to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect; except as otherwise disclosed in the Registration Statement, all of the issued and outstanding capital stock of each such Subsidiary has been duly authorized and validly issued, is fully paid and non-assessable and is owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity; none of the outstanding shares of capital stock of any Subsidiary was issued in violation of the preemptive or similar rights of any securityholder of such Subsidiary.  The only subsidiaries of the Company are the subsidiaries listed on Exhibit 21 to the Registration Statement.

(ix)              Authorization and Description of Securities.  The Securities to be purchased by the Underwriters from the Company have been duly authorized for issuance and sale to the Underwriters pursuant to this Agreement and, when issued and delivered by the Company pursuant to this Agreement against payment of the consideration set forth herein, will be validly issued and fully paid and non-assessable; the Common Stock conforms to all statements relating thereto contained in the Prospectus and such description conforms to the rights set forth in the instruments defining the same; no holder of the Securities will be subject to personal liability by reason of being such a holder; and the issuance of the Securities is not subject to the preemptive or other similar rights of any securityholder of the Company.

the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or any subsidiary’s principal suppliers, manufacturers, customers or contractors, which, in either case, would result in a Material Adverse Effect.

(xii)             Absence of Proceedings.  There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company, threatened, against or affecting the Company or any subsidiary, which is required to be disclosed in the Registration Statement (other than as disclosed therein), or which would reasonably be expected to result in a Material Adverse Effect, or which might materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in this Agreement (including the Pre-Offering Transactions) or the performance by the Company of its obligations hereunder; the aggregate of all pending legal or governmental proceedings to which the Company or any subsidiary is a party or of which any of their respective property or assets is the subject which are not described in the Registration Statement, including ordinary routine litigation incidental to the business, would not reasonably be expected to result in a Material Adverse Effect.

(xiii)            Accuracy of Exhibits.  There are no contracts or documents which are required to be described in the Registration Statement or the Prospectus or to be filed as exhibits thereto which have not been so described and filed as required.

(xiv)           Possession of Intellectual Property.  The Company and its subsidiaries own or possess, or can acquire on reasonable terms, adequate patents, patent rights, licenses, inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), trademarks, service marks, trade names or other intellectual property (collectively, “Intellectual Property”) necessary to carry on the business now operated by them, and neither the Company nor any of its subsidiaries has received any notice or is otherwise aware of any infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances which would render any Intellectual Property invalid or inadequate to protect the interest of the Company or any of its subsidiaries therein, and which infringement or conflict (if the subject of any unfavorable decision, ruling or finding) or invalidity or inadequacy, singly or in the aggregate, would result in a Material Adverse Effect.

(xv)            Absence of Further Requirements.  No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency is necessary or required for the performance by the Company of its obligations hereunder, in connection with the offering, issuance or sale of the Securities hereunder or the consummation of the transactions contemplated by this Agreement (including the Pre-Offering Transactions and the use of the proceeds of the sale of the Securites as described in the Prospectus under “Use of Proceeds”), except  such as have been already obtained or as may be required under the 1933 Act or the 1933 Act Regulations or state securities laws.

7

(xvi)           Absence of Manipulation.  Neither the Company nor any affiliate of the Company has taken, nor will the Company or any affiliate take, directly or indirectly, any action which is designed to or which has constituted or which would be expected to cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(xvii)          Possession of Licenses and Permits.  The Company and its subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct the business now operated by them, except where the failure so to possess would not, singly or in the aggregate, result in a Material Adverse Effect; the Company and its subsidiaries are in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, result in a Material Adverse Effect; all of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not, singly or in the aggregate, result in a Material Adverse Effect; and neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Effect.

(xviii)         Title to Property.  The Company and its subsidiaries have good and marketable title to all real property owned by the Company and its subsidiaries and good title to all other properties owned by them, in each case, free and clear of all mortgages, pledges, liens, security interests, claims, restrictions or encumbrances of any kind except such as (a) are described in the Prospectus or (b) do not, singly or in the aggregate, materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company or any of its subsidiaries; and all of the leases and subleases material to the business of the Company and its subsidiaries, considered as one enterprise, and under which the Company or any of its subsidiaries holds properties as described in the Prospectus, are in full force and effect, and neither the Company nor any subsidiary has any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or any subsidiary under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company or such subsidiary to the continued possession of the leased or subleased premises under any such lease or sublease, except as would not reasonably be expected to result in a Material Adverse Effect.

(xix)            Investment Company Act.  The Company is not required, and upon the issuance and sale of the Securities as herein contemplated and the application of the net proceeds therefrom as described in the Prospectus will not be required, to register as an “investment company” under the Investment Company Act of 1940, as amended (the “1940 Act”).

8

(xx)             Environmental Laws.  Except as described in the Registration Statement and except as would not, singly or in the aggregate, result in a Material Adverse Effect, (A) neither the Company nor any of its subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, 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 the release, to the knowledge of the Company, or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products, asbestos containing materials or mold (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (B) the Company and its subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements, (C) there are no pending or threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any of its subsidiaries and (D) to the knowledge of the Company, there are no events, facts or circumstances that would reasonably be expected to form the basis of any liability or obligation of the Company or any of its subsidiaries, including, without limitation, any order, decree, plan or agreement requiring clean-up or remediation, or any action, suit or proceeding by any private party or governmental body or agency, against or affecting the Company or any of its subsidiaries relating to any Hazardous Materials or any Environmental Laws.

(xxi)            Registration Rights.  Except as described in the Registration Statement, there are no persons with registration rights or other similar rights to have any securities registered pursuant to the Registration Statement (except for rights which have been complied with or waived) or otherwise registered by the Company under the 1933 Act.

(xxii)           Related Party Transactions.  No relationship, direct or indirect, exists between or among the Company or any affiliate of the Company, on the one hand, and any director, officer, stockholder, customer or supplier of any of them, on the other hand, which is required by the 1933 Act or by the 1933 Act Regulations to be described in the Registration Statement or the Prospectus which is not so described or is not described as required.

(xxiii)          Suppliers.  Except as described in the Registration Statement, or as would not reasonably be expected to have a Material Adverse Effect, no supplier of merchandise to the Company or any of its subsidiaries has ceased shipments of merchandise to the Company or indicated an interest in decreasing or ceasing its sales to the Company or materially increasing pricing or otherwise modifying its relationship

9

with the Company, other than in the normal and ordinary course of business consistent with past practices.

(xxiv)          Insurance.  The Company and its subsidiaries carry insurance in such amounts and covering such risks as are adequate in the reasonable judgment of the Company for the conduct of their respective businesses and the value of their respective properties and the Company believes that, following the completion of the offering, it and its subsidiaries will continue to be able to obtain insurance on substantially the same terms as it now possesses.

(xxv)           Accounting Controls.  The Company and its subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurances that (A) transactions are executed in accordance with management’s general or specific authorization;  (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets;  (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.

(xxvi)          Disclosure Controls.  The Company and its subsidiaries employ disclosure controls and procedures that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and is accumulated and communicated to the Company’s management, including its principal executive officer or officers and principal financial officer or officers, as appropriate to allow timely decisions regarding disclosure.

(xxvii)         No Extension of Credit.  The Company has not, directly or indirectly, extended credit, arranged to extend credit, or renewed any extension of credit, in the form of a personal loan, to any director or executive officer of the Company or its subsidiaries, or to or for the family member or affiliate of any director or executive officer of the Company or its subsidiaries, except for extensions of credit no longer outstanding.

(xxviii)        Sarbanes-Oxley Act.  As of the Closing Time, the Company and any of the Company’s directors or officers, in their capacities as such, will comply with any applicable provision of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the “Sarbanes Oxley Act”).

(xxix)          Tax Returns.  The Company and its subsidiaries have filed all federal, state, local and foreign tax returns that are required to have been filed by them pursuant to applicable foreign, federal, state, local or other law or have duly requested extensions thereof, except insofar as the failure to file such returns or request such extensions would not reasonably be expected to result in a Material Adverse Effect, and have paid all taxes due pursuant to such returns or pursuant to any assessment received by the Company and

10

its Subsidiaries, except for such taxes or assessments, if any, as are being contested in good faith and as to which adequate reserves have been provided or where the failure to pay would not reasonably be expected to result in a Material Adverse Effect.  The charges, accruals and reserves on the books of the Company in respect of any income and corporation tax liability of the Company and each subsidiary for any years not finally determined are adequate to meet any assessments or re-assessments for additional income tax for any years not finally determined, except to the extent of any inadequacy that would not reasonably be expected to result in a Material Adverse Effect.

(xxx)           Pre-Offering Transactions.  The Pre-Offering Transactions have been duly authorized by the Company and have been consummated by the Company on or before the Closing Time.  The Company’s Amended and Restated Charter as described in the Prospectus has been approved by all necessary corporate, board and shareholder action, does not require any governmental or third party approval and will be in full force and effect on or before the Closing Time.  The issuance of shares of Common Stock in accordance with the Pre-Offering Transactions does not require registration under the 1933 Act or the 1933 Act Regulations and will not be integrated with the sale of the Securities hereunder.

(b)           Representations and Warranties by the Selling Shareholders.  Each Selling Shareholder severally and not jointly represents and warrants to each Underwriter as of the date hereof, as of the Closing Time, and, if the Selling Shareholder is selling Option Securities on a Date of Delivery, as of each such Date of Delivery, and agrees with each Underwriter, as follows:

(i)               Accurate Disclosure.  The information which relates specifically to each Selling Shareholder, as set forth under the caption “Principal and Selling Shareholders” does not contain, and, as amended or supplemented, if applicable, will not contain any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein; there are no agreements between such Selling Shareholder and any other Selling Shareholder that would be required to be described in the Prospectus that are not so described; and each such Selling Shareholder is not prompted to sell the Securities to be sold by such Selling Shareholder hereunder by any information concerning the Company or any subsidiary of the Company which is not set forth in the Prospectus.

(ii)              Authorization of this Agreement.  This Agreement has been duly authorized, executed and delivered by or on behalf of such Selling Shareholder.

(iii)             Authorization of Power of Attorney and Custody Agreement.  The Power of Attorney and Custody Agreement, in the form heretofore furnished to the Representatives (the “Power of Attorney and Custody Agreement”), has been duly authorized, executed and delivered by such Selling Shareholder and, assuming the due authorization, execution and delivery by the other parties thereto,  is the valid and binding agreement of such Selling Shareholder; the Custodian (as defined below) is authorized to

11

deliver the Securities to be sold by such Selling Shareholder hereunder and to accept payment therefore; and each Attorney-in-Fact is authorized to execute and deliver this Agreement and the certificate referred to in Section 5(f) or that may be required pursuant to Sections 5(n) and 5(o) on behalf of such Selling Shareholder, to exercise the Options and/or Warrants for shares of Common Stock, to sell, assign and transfer to the Underwriters the Securities to be sold by such Selling Shareholder, as provided in Section 2(a) hereof, to agree to an upsizing or downsizing of the Offering or cutback in the number of Securities to be sold by the Selling Shareholder, provided that any such upsizing or downsizing or cutback is allocated on a pro rata basis among the Selling Shareholders, to determine the purchase price to be paid by the Underwriters to such Selling Shareholder, to authorize the delivery of the Shares to be sold by such Selling Shareholder under the Purchase Agreement, to take actions and execute and deliver all such agreements, documents,  instruments and certificates as may be necessary or desirable, otherwise to act on behalf of such Selling Shareholder in connection with this Agreement, Pre-Offering Transactions (including, without limitation, the stock split of the Common Stock),  the sale of Shares to the Underwriters and the offering of Securities by the Underwriters and the registration of Securities by the Company and approve any of the Pre-Offering Transactions on behalf of the Selling Shareholder.

(iv)             Noncontravention.  The execution and delivery of this Agreement and the Power of Attorney and Custody Agreement and the sale and delivery of the Securities to be sold by such Selling Shareholder and the consummation of the transactions contemplated herein and compliance by such Selling Shareholder with its obligations hereunder do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default under, or result in the creation or imposition of any tax, lien, charge or encumbrance upon the Securities to be sold by such Selling Shareholder or any property or assets of such Selling Shareholder pursuant to any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, license, lease or other agreement or instrument to which such Selling Shareholder is a party or by which such Selling Shareholder may be bound, or to which any of the property or assets of such Selling Shareholder is subject, including any applicable state laws requiring any spousal or other consent in connection with the disposition of property by the Selling Stockholder (except for such conflicts, breaches or defaults that would adversely effect such Selling Shareholder’s ability to fulfill its obligations hereunder or under the Power of Attorney and Custody Agreement in any material respect), nor will such action result in any violation of the provisions of the charter or by-laws or other organizational instrument of such Selling Shareholder, if applicable, or any applicable treaty, law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over such Selling Shareholder or any of its properties (except for violations of any treaty, law, statute, rule, regulation, judgment, order, writ or decree that would adversely effect such selling shareholder’s ability to fulfill its obligations hereunder or under the Power of Attorney and Custody Agreement in any material respect). Such Selling Shareholder has

(b)           Option Securities.  In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company and the Selling Shareholders, acting severally and not jointly, hereby grant an option to the Underwriters, severally and not jointly, to purchase up to an additional 1,243,200 shares of Common Stock set forth in Schedule B, at the price per share set forth in Schedule C, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities.  The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time on one or more occasions only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by Merrill Lynch to the Company and the Selling Shareholders setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities.  Any such time and date of delivery (a “Date of Delivery”) shall be determined by Merrill Lynch, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined.  If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, first from the Selling Shareholders on a pro rata basis in accordance with the number of Option Securities of each of the Selling Shareholders set forth in Schedule B and then from the Company, subject in each case to such adjustments as Merrill Lynch in its discretion shall make to eliminate any sales or purchases of fractional shares.

(c)           Payment.  Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Fried, Frank, Harris, Shriver & Jacobson LLP, One New York Plaza, New York, New York 10004, or at such other place as shall be agreed upon by the Representatives and the Company and the Selling Shareholders, at 9:00 A.M.

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representatives and the Company and the Selling Shareholders, on each Date of Delivery as specified in the notice from Merrill Lynch to the Company and the Selling Shareholders.

(Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be.

24

1, 6, 7 and 8 shall survive any such termination and remain in full force and effect.

SECTION 6.           Indemnification.

(a)           Indemnification of Underwriters by the Company.   The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, as such term is defined in Rule 501(b) under the 1933 Act (each, an “Affiliate”), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i)            against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii)           against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(e) below) any such settlement is effected with the written consent of the Company; and

(iii)          against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through Merrill Lynch expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); and provided further, however, that the Company will not be liable to any of the Underwriters with respect to the Prospectus to the extent that any such loss, liability, claim, damage or expense resulted from the fact that such

25

Underwriter, in contravention of a requirement of this Agreement or applicable law, sold Securities to a person to whom such Underwriter failed to send or give, at or prior to the Closing Time or Date of Delivery, as applicable, a copy of the final prospectus, as then amended or supplemented if the Company has previously furnished copies thereof (sufficiently in advance of the Closing Time or Date of Delivery, as applicable, to allow for distribution by the Closing Time or Date of Delivery, as applicable,) to the Underwriters and the loss, liability, claim, damage or expense of such Underwriter resulted from an untrue statement or omission of a material fact contained in or omitted from the preliminary prospectus which was corrected in the final prospectus as, if applicable, amended or supplemented prior to the Closing Time or Date of Delivery, as applicable, and such prospectus was required by law to be delivered at or prior to the written confirmation of the sale to such person.

(b)           Indemnification of Underwriters by Selling Shareholders.  Each Selling Shareholder, severally and not jointly, agrees to indemnify and hold harmless each Underwriter, its Affiliates and selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the extent and in the manner set forth in clauses (a)(i), and (ii) above; provided, however, that this indemnity agreement shall only apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by such Selling Stockholder expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto).  It is hereby understood that each Selling Shareholder shall be deemed to have provided the information with respect to such Selling Shareholder as set forth under the caption “Principal and Selling Shareholders.”  Notwithstanding anything to the contrary contained herein, the extent of such Selling Shareholder’s liability under this Agreement shall be limited to the net proceeds received by such Selling Shareholder from the sale of the shares of Common Stock by such Selling Shareholder pursuant to this Agreement.

(c)           Acknowledgement by the Company and the Selling Shareholders.  The Company and the Selling Shareholders also acknowledge and agree that (i) the purchase and sale of any Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters of such Securities, on the other hand, (ii) in connection with the public offering of the Securities and the process leading to such transaction each Underwriter will act solely as a principal and not as agent or fiduciary of the Company or its stockholders, creditors, employees or any other party, (iii) no Underwriter will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of Securities contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter will have any obligation to the Company with respect to the Offering except the obligations expressly set forth herein, (iv) any Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (v) the Underwriters have not provided and will not

26

provide any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and the Company has consulted and will consult its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

(d)           Indemnification of Company, Directors and Officers and Selling Shareholders.  Each Underwriter severally agrees to indemnify and hold harmless the Company, their directors, each of their officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and each Selling Shareholder and each person, if any, who controls any Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through Merrill Lynch expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).  The parties hereto agree that such written information consists of:  the information in the table under the caption “Underwriting,” the information in the first paragraph under the caption “Underwriting—Commissions and Discounts,” and the information under the caption “Underwriting—Internet Distribution”; provided however, that the Underwriters shall not be liable for any losses, liabilities, claims, damages or expenses arising out of or based upon the Company’s failure to perform its obligations under Section 3(a) of this Agreement.

(e)           Actions against Parties; Notification.  Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement.  In the case of parties indemnified pursuant to Section 6(a) and 6(b) above, counsel to the indemnified parties shall be selected by Merrill Lynch, and, in the case of parties indemnified pursuant to Section 6(c) above, counsel to the indemnified parties shall be selected by the Company.  An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party.  In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.  No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof

27

(whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) 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.

(f)            Settlement without Consent if Failure to Reimburse.  If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel with respect to a claim in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a) (ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(g)           Other Agreements with Respect to Indemnification.  The provisions of this Section shall not affect any agreement among the Company and the Selling Shareholders with respect to indemnification.

SECTION 7.           Contribution.  If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Shareholders on the one hand and of the Underwriters on the other hand in connection with the statements or omissions, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the Selling Shareholders and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus.

28

The relative fault of the Company and the Selling Shareholders on the one hand and the Underwriters 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 relates to information supplied by the Company or the Selling Shareholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters 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 above in this Section 7.  The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission, and (ii) no Selling Shareholder shall be required to contribute any amount in excess of the net proceeds received by such Selling Shareholder from the sale of its Securities pursuant to this Agreement.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or any Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company or such Selling Shareholder, as the case may be.  The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.  The Selling Shareholders’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Securities set forth opposite their respective names in Schedule B hereto and not joint.

The provisions of this Section 7 shall not affect any agreement among the Company and the Selling Shareholders with respect to contribution.

29

SECTION 8.           Representations, Warranties and Agreements to Survive.  All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries or any of the Selling Shareholders submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any  person controlling any Underwriter, its officers or directors, any person controlling the Company or any person controlling the Selling Shareholders and (ii) delivery of and payment for the Securities.

SECTION 9.           Termination of Agreement.

(a)           Termination; General.  The Representatives may terminate this Agreement, by notice to the Company and the Selling Shareholders, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the Nasdaq National Market, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (v) if a banking moratorium has been declared by either Federal or New York authorities.

(b)           Liabilities.  If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect.

SECTION 10.         Default by One or More of the Underwriters.  If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms

30

herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a)           if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b)           if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Company to sell the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Selling Shareholders to sell the relevant Option Securities, as the case may be, either (i) the Representatives or (ii)  the Company and any Selling Shareholder shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements.  As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11.         Default by one or more of the Selling Shareholders or the Company.  (a) If a Selling Shareholder shall fail at Closing Time or at a Date of Delivery to sell and deliver the number of Securities which such Selling Shareholders are obligated to sell hereunder, and the remaining Selling Shareholders do not exercise the right hereby granted to increase, pro rata or otherwise, the number of Securities to be sold by them hereunder to the total number to be sold by all Selling Shareholders as set forth in Schedule B hereto, then the Underwriters may, at option of the Representatives, by notice from the Representatives to the Company and the non-defaulting Selling Shareholders, either (i) terminate this Agreement without any liability on the fault of any non-defaulting party except that the provisions of Sections 1, 4, 6, 7 and 8 shall remain in full force and effect or (ii) elect to purchase the Securities which the non-defaulting Selling Shareholders and the Company have agreed to sell hereunder.  No action taken pursuant to this Section 11 shall relieve any Selling Shareholder so defaulting from liability, if any, in respect of such default.

In the event of a default by any Selling Shareholder as referred to in this Section 11, each of the Representatives, the Company and the non-defaulting Selling Shareholders shall have the right to postpone Closing Time or Date of Delivery for a period not exceeding seven days in

31

order to effect any required change in the Registration Statement or Prospectus or in any other documents or arrangements.

(b)           If the Company shall fail at Closing Time or at the Date of Delivery to sell the number of Securities that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any nondefaulting party; provided, however, that the provisions of Sections 1, 4, 6, 7 and 8 shall remain in full force and effect.  No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.

SECTION 12.         Tax Disclosure.  Notwithstanding any other provision of this Agreement, from the commencement of discussions with respect to the transactions contemplated hereby, the Company (and each employee, representative or other agent of the Company) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure (as such terms are used in Sections 6011, 6111 and 6112 of the U.S. Code and the Treasury Regulations promulgated thereunder) of the transactions contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided relating to such tax treatment and tax structure.

SECTION 13.         Notices.  All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.  Notices to the Underwriters shall be directed to the Representatives at 4 World Financial Center, New York, New York 10281-1201, attention of Michael L. Santini; with a copy to Fried, Frank, Harris, Shriver & Jacobson LLP, One New York Plaza, New York, New York 10004, attention of Valerie Ford Jacob, Esq.; and notices to the Company shall be directed to RBC Bearings Incorporated, One Tribology Center, Oxford, CT  06478, attention of President; with a copy to Kirkland & Ellis LLP, Citigroup Center, 153 East 53^rd Street, New York, NY 10022, attention of Joshua N.

Korff, Esq; with a copy to Fox Rothschild LLP, 2700 Kelly Road, Suite 300, Warrington, PA 18976, attention of Elizabeth D. Sigety, Esq.

SECTION 14.         Parties.  This Agreement shall each inure to the benefit of and be binding upon the Underwriters, the Company and the Selling Shareholders and their respective successors.  Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and the Selling Shareholders and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.  This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and the Selling Shareholders and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.  No

32

purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 15.         GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

SECTION 16.         TIME.  TIME SHALL BE OF THE ESSENCE OF THIS AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

(a)                                  Dividends.  Except as otherwise provided by the Delaware General Corporation Law or this Amended and Restated Certificate of Incorporation (this “Certificate of Incorporation”), the holders of Common Stock: (i) subject to the rights of holders of any series of Preferred Stock, shall share ratably, on a per share basis, in all dividends and other distributions payable in cash, securities or other property of the Corporation as may be declared thereon by the Board of Directors from time to time out of assets or funds of the Corporation legally available therefor; and (ii) are subject to all the powers, rights, privileges, preferences and priorities of any series of Preferred Stock as provided herein or in any resolution or resolutions adopted by the Board of Directors pursuant to authority expressly vested in it by the provisions of Section 2 of this ARTICLE FOUR.

(b)                                 Conversion Rights.  The Common Stock shall not be convertible into, or exchangeable for, shares of any other class or classes or of any other series of the same class of the Corporation’s capital stock.

(c)                                  Preemptive Rights.  No holder of Common Stock shall have any preemptive rights with respect to the Common Stock or any other securities of the Corporation, or to any obligations convertible (directly or indirectly) into securities of the Corporation whether now or hereafter authorized.

(d)                                 Voting Rights.  Except as otherwise provided by the Delaware General Corporation Law or this Certificate of Incorporation and subject to the rights of holders of any series of Preferred Stock, all of the voting power of the stockholders of the Corporation shall be vested in the holders of the Common Stock, and each holder of Common Stock shall have one vote for each share held by such holder on all matters voted upon by the stockholders of the Corporation.

(e)                                  Liquidation Rights.  In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, after payment or provision for payment of the Corporation’s debts and subject to the rights of the holders of shares of Preferred Stock upon such dissolution, liquidation or winding up, the remaining net assets of the Corporation shall be distributed among holders of shares of Common Stock ratably on a per share basis.  A merger or consolidation of the Corporation with or into any other corporation or other entity, or a sale or conveyance of all or any part of the assets of the Corporation (which shall not in fact result in the liquidation of the Corporation and the distribution of assets to its stockholders) shall not be deemed to be a voluntary or involuntary liquidation or dissolution or winding up of the Corporation within the meaning of this Section 3(e).

(f)                                    Registration or Transfer.  The Corporation shall keep or cause to be kept at its principal office (or such other place as the Corporation reasonably designates) a register for the registration of Common Stock.  Upon the surrender of any certificate representing shares of any class of Common Stock at such place, the Corporation shall, at the request of the registered holder of such certificate, execute and deliver a new certificate or certificates in exchange therefor representing in the aggregate the number of shares of such class represented by the surrendered certificate, and the Corporation forthwith shall cancel such surrendered certificate.  Each such new certificate will be registered in such name and will represent such number of shares of such class as is requested by the holder of the surrendered certificate and shall be

2

substantially identical in form to the surrendered certificate.  The issuance of new certificates shall be made without charge to the holders of the surrendered certificates for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such issuance.

(g)                                 Replacement.  Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder will be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing one or more shares of any class of Common Stock, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor, its own agreement will be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such class represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate.

(h)                                 Notices.  All notices referred to herein shall be in writing, shall be delivered personally or by first class mail, postage prepaid, and shall be deemed to have been given when so delivered or mailed to the Corporation at its principal executive offices and to any stockholder at such holder’s address as it appears in the stock records of the Corporation (unless otherwise specified in a written notice to the Corporation by such holder).

(i)                                     Fractional Shares.  In no event will holders of fractional shares be required to accept any consideration in exchange for such shares other than consideration which all holders of Common Stock are required to accept.

                Section 4.               Reclassification of Class A Common Stock and Class B Common Stock.  Upon this Certificate of Incorporation becoming effective in accordance with the Delaware General Corporate Law (the "Effective Time"): (i) each share of Class A Common Stock, par value $0.01 per share ("Old Class A Common"), issued and outstanding immediately prior to the Effective Time shall be reclassified as, and converted into, 2.5 validly issued, fully paid and nonassessble shares of Common Stock and (ii) each share of Class B Common Stock, par value $0.01 per share ("Old Class B Common"), issued and outstanding immediately prior to the Effective Time shall be reclassified as, and converted into, 2.5 validly issued, fully paid and nonassessble shares of Common Stock, (such reclassification as, and the conversion of Old Class A Common and Old Class B Common, respectively, into Common Stock, the "Reclassification").  Each stock certificate that, immediately prior to the Effective Time, represented shares of Old Class A Common or Old Class B Common, respectively, shall, from and after the Effective Time, automatically and without the necessity of presenting the same for exchange, represent the number of shares of Common Stock into which the shares represented by such certificate shall have been reclassified as of the Effective Time after giving effect to the Reclassification; provided, however, that each person holding of record a stock certificate or certificates that represented Old Class A Common or Old Class B Common, respectively, shall receive, upon surrender of such certificate, a new certificate or certificates evidencing and representing the number of shares of Common Stock into which such shares of Old Class A Common or Old Class B Common, respectively, shall have been reclassified in accordance with the Reclassification.

ARTICLE FIVE

The Corporation is to have perpetual existence.

ARTICLE SIX

Section 1.                                            Number, Election and Term of Office.  At each annual meeting of stockholders, directors of the Corporation shall be elected to hold office until the expiration of the term for which they are elected, and until their successors have been duly elected and qualified; except that if any such election shall be not so held, such election shall take place at stockholders’ meeting called and held in accordance with the Delaware General Corporation Law.  The directors of the Corporation shall be divided into 3 classes as nearly equal in size as is practicable, hereby designated Class I, Class II and Class III.  The term of office of the initial Class I directors shall expire at the next succeeding annual meeting of stockholders, the term of office of the initial Class II directors shall expire at the second succeeding annual meeting of stockholders and the term of office of the initial Class III directors shall expire at the third succeeding annual meeting of the stockholders.  For the purposes hereof, the initial Class I, Class II and Class III directors shall be those directors elected by the stockholders of the Corporation in connection with the adoption of this Certificate of Incorporation.  At each annual meeting after the first annual meeting of stockholders, directors to replace those of a Class whose terms expire at such annual meeting shall be elected to hold office until the third succeeding annual meeting and until their respective successors shall have been duly elected and qualified.  If the number of directors is hereafter changed, any newly created directorships or decrease in directorships shall be so apportioned among the classes as to make all classes as nearly equal in number as practicable.

Section 2.                                            Vacancies.  Vacancies occurring on the Board of Directors for any reason may be filled by vote of a majority of the remaining members of the Board of Directors, although less than a quorum, at any meeting of the Board of Directors.  A person so elected by the Board of Directors to fill a vacancy shall hold office until the next succeeding annual meeting of stockholders of the Corporation and until his or her successor shall have been duly elected and qualified.

ARTICLE SEVEN

In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to make, alter, amend or repeal the Bylaws of the Corporation.

ARTICLE EIGHT

Section 1.                                            Limitation of Liability.

(a)                                  To the fullest extent permitted by the Delaware General Corporation Law as it now exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than permitted prior thereto), and except as otherwise provided in the Corporation’s Bylaws, no Director of the Corporation shall be liable to the Corporation or its stockholders for monetary damages arising from a breach of fiduciary duty owed to the Corporation or its stockholders.

(b)                                 Any repeal or modification of the foregoing paragraph by the stockholders of the Corporation shall not adversely affect any right or protection of a Director of the Corporation existing at the time of such repeal or modification.

Section 2.                                            Right to Indemnification.  Each person who was or is made a party or is threatened to be made a party to or is otherwise involved (including involvement as a witness) in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”), by reason of the fact that he or she is or was a Director or officer of the Corporation or, while a Director, officer or other employee of the Corporation, is or was serving at the request of the Corporation as a Director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a Director or officer or in any other capacity while serving as a Director or officer, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than permitted prior thereto), against all expense, liability and loss (including attorneys’ fees, judgments, fines, excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased to be a Director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators; provided, however, that, except as provided in Section 3 of this ARTICLE EIGHT with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation.  The right to indemnification conferred in this Section 2 of this ARTICLE EIGHT shall be a contract right and shall include the obligation of the Corporation to pay the expenses incurred in defending any such proceeding in advance of its final disposition (an “advance of expenses”); provided, however, that, if and to the extent that the Delaware General Corporation Law requires, an advance of expenses incurred by an indemnitee in his or her capacity as a Director or officer (and not in any other capacity in which service was or is rendered by such indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon delivery to the Corporation of an undertaking (an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (a “final adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under this Section 2 or otherwise.  The Corporation may, by action of its Board of Directors, provide indemnification to employees and agents of the Corporation with the same or lesser scope and effect as the foregoing indemnification of Directors and officers.

Section 3.                                            Procedure for Indemnification.  Any indemnification of a Director or officer of the Corporation or advance of expenses under Section 2 of this ARTICLE EIGHT

4

shall be made promptly, and in any event within forty-five days (or, in the case of an advance of expenses, twenty days), upon the written request of the Director or officer.  If a determination by the Corporation that the Director or officer is entitled to indemnification pursuant to this ARTICLE EIGHT is required, and the Corporation fails to respond within sixty days to a written request for indemnity, the Corporation shall be deemed to have approved the request.  If the Corporation denies a written request for indemnification or advance of expenses, in whole or in part, or if payment in full pursuant to such request is not made within forty-five days (or, in the case of an advance of expenses, twenty days), the right to indemnification or advances as granted by this ARTICLE EIGHT shall be enforceable by the Director or officer in any court of competent jurisdiction.  Such person’s costs and expenses incurred in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation.  It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of expenses where the undertaking required pursuant to Section 2 of this ARTICLE EIGHT, if any, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the Delaware General Corporation Law for the Corporation to indemnify the claimant for the amount claimed, but the burden of such defense shall be on the Corporation.  Neither the failure of the Corporation (including its Board of Directors, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.  The procedure for indemnification of other employees and agents for whom indemnification is provided pursuant to Section 2 of this ARTICLE EIGHT shall be the same procedure set forth in this Section 3 for Directors or officers, unless otherwise set forth in the action of the Board of Directors providing indemnification for such employee or agent.

Section 4.                                            Insurance.  The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was a Director, officer, employee or agent of the Corporation or was serving at the request of the Corporation as a Director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan, against any expense, liability or loss asserted against him or her and incurred by him or her in any such capacity, whether or not the Corporation would have the power to indemnify such person against such expenses, liability or loss under the Delaware General Corporation Law.

Section 5.                                            Service for Subsidiaries.  Any person serving as a Director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture or other enterprise, at least 50% of whose equity interests are owned by the Corporation (a “subsidiary” for this ARTICLE EIGHT) shall be conclusively presumed to be serving in such capacity at the request of the Corporation.

Section 6.                                            Reliance.  Persons who after the date of the adoption of this provision become or remain Directors or officers of the Corporation or who, while a Director, officer or

5

other employee of the Corporation, become or remain a Director, officer, employee or agent of a subsidiary, shall be conclusively presumed to have relied on the rights to indemnity, advance of expenses and other rights contained in this ARTICLE EIGHT in entering into or continuing such service.  The rights to indemnification and to the advance of expenses conferred in this ARTICLE EIGHT shall apply to claims made against an indemnitee arising out of acts or omissions which occurred or occur both prior and subsequent to the adoption hereof.

Section 7.                                            Non-Exclusivity of Rights.  The rights to indemnification and to the advance of expenses conferred in this ARTICLE EIGHT shall not be exclusive of any other right which any person may have or hereafter acquire under this Restated Certificate or under any statute, by-law, agreement, vote of stockholders or disinterested Directors or otherwise.

Section 8.                                            Merger or Consolidation.  For purposes of this ARTICLE EIGHT, references to the “Corporation” shall include, in addition to the resulting Corporation, any constituent Corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its Directors, officers and employees or agents, so that any person who is or was a Director, officer, employee or agent of such constituent Corporation, or is or was serving at the request of such constituent Corporation as a Director, officer, employee or agent of another Corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this ARTICLE EIGHT with respect to the resulting or surviving Corporation as he or she would have with respect to such constituent Corporation if its separate existence had continued.

Section 9.                                            Savings Clause.  If this ARTICLE EIGHT or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each person entitled to indemnification under Section 2 of this ARTICLE EIGHT as to all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, ERISA excise taxes and penalties, penalties and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such person and for which indemnification is available to such person pursuant to this ARTICLE EIGHT to the full extent permitted by any applicable portion of this ARTICLE EIGHT that shall not have been invalidated and to the full extent permitted by applicable law.

ARTICLE NINE

Meetings of stockholders may be held within or without the State of Delaware, as the Bylaws may provide.  The books of the Corporation may be kept (subject to any provision contained in the statutes) outside of the State of Delaware at such place or places as may be designated from time to time by the Board of Directors or in the Bylaws of the Corporation.

ARTICLE TEN

For so long as any security of the Company is registered under Section 12 of the Securities Exchange Act of 1934: (i) the stockholders of the Corporation may not take any action by written consent in lieu of a meeting, and must take any actions at a duly called annual or special meeting of stockholders and the power of stockholders to consent in writing without a

6

meeting is specifically denied; and (ii) special meetings of stockholders of the Corporation may be called only by the Board of Directors pursuant to a resolution adopted by the affirmative vote of the majority of the total number of directors then in office.

ARTICLE ELEVEN

Section 1.                                            Certain Acknowledgments.  In recognition and anticipation that: (i) the partners, principals, directors, officers, members, managers and/or employees of Whitney & Co., LLC and its affiliates (“Whitney”) may serve as directors and/or officers of the Corporation, (ii)  Whitney may engage in the same or similar activities or related lines of business as those in which the Corporation, directly or indirectly, may engage and/or other business activities that overlap with or compete with those in which the Corporation, directly or indirectly, may engage, and (iii) that the Corporation and its subsidiaries may engage in material business transactions with Whitney and that the Corporation is expected to benefit therefrom, the provisions of this ARTICLE ELEVEN are set forth to regulate and define the conduct of certain affairs of the Corporation as they may involve Whitney and their respective directors, officers, members, managers and/or employees, and the powers, rights, duties and liabilities of the Corporation and its officers, directors and stockholders in connection therewith.

Section 2.                                            Competition and Corporate Opportunities.  Whitney shall not have any duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as the Corporation or any of its subsidiaries.  In the event that Whitney acquires knowledge of a potential transaction or matter which may be a corporate opportunity for itself and the Corporation or any of its subsidiaries, neither the Corporation nor any of its subsidiaries shall have any expectancy in such corporate opportunity, and neither Whitney shall have any duty to communicate or offer such corporate opportunity to the Corporation or any of its subsidiaries and may pursue or acquire such corporate opportunity for itself or direct such corporate opportunity to another person.

Section 3.                                            Allocation of Corporate Opportunities.  In the event that a director or officer of the Corporation who is also a partner, principal, director, officer, member, manager and/or employee of Whitney acquires knowledge of a potential transaction or matter which may be a corporate opportunity for the Corporation or any of its subsidiaries and Whitney, neither the Corporation nor any of its subsidiaries shall have any expectancy in such corporate opportunity unless such corporate opportunity is expressly offered to such person solely in his or her capacity as a director or officer of the Corporation.

Section 4.                                            Certain Matters Deemed Not Corporate Opportunities.  In addition to and notwithstanding the foregoing provisions of this ARTICLE ELEVEN, a corporate opportunity shall not be deemed to belong to the Corporation if it is a business opportunity that the Corporation is not financially able or contractually permitted or legally able to undertake, or that is, from its nature, not in the line of the Corporation’s business or is of no practical advantage to it or that is one in which the Corporation has no interest or reasonable expectancy.

Section 5.                                            Agreements and Transactions with Whitney.  In the event that Whitney enters into an agreement or transaction with the Corporation or any of its subsidiaries, a director or officer of the Corporation who is also a partner, principal, director, officer, member, manager

7

and/or employee of Whitney, as applicable, shall have fully satisfied and fulfilled the fiduciary duty of such director or officer to the Corporation and its stockholders with respect to such agreement or transaction, if:

(a)                                  The agreement or transaction was approved, after being made aware of the material facts of the relationship between each of the Corporation or subsidiary thereof and Whitney, and the material terms and facts of the agreement or transaction, by (i) an affirmative vote of a majority of the members of the Board of Directors of the Corporation who are not persons or entities with a material financial interest in the agreement or transaction (“Interested Persons”) or (ii) an affirmative vote of a majority of the members of a committee of the Board of Directors of the Corporation consisting of members who are not Interested Persons;

(b)                                 The agreement or transaction was fair to the Corporation at the time the agreement or transaction was entered into by the Corporation; or

(c)                                  The agreement or transaction was approved by an affirmative vote of a majority of the shares of the Corporation’s Common Stock entitled to vote, excluding Whitney, and any Interested Person; provided that if no Common Stock is then outstanding a majority of the voting power of the Corporation’s capital stock entitled to vote, excluding Whitney and any other Interested Person, as applicable.

Section 6.                                            Amendment of this Article.  Notwithstanding anything to the contrary elsewhere contained in this Certificate of Incorporation, the affirmative vote of the holders of at least 80% of the voting power of all shares of Common Stock then outstanding, voting together as a single class, shall be required to alter, amend or repeal, or to adopt any provision inconsistent with, this ARTICLE ELEVEN.

Section 7.                                            Deemed Notice.  Any person or entity purchasing or otherwise acquiring any interest in any shares of the Corporation shall be deemed to have notice or and to have consented to the provisions of this ARTICLE ELEVEN.

ARTICLE TWELVE

ARTICLE FOURTEEN

The Corporation expressly elects to be governed by Section 203 of the Delaware General Corporation Law.  Notwithstanding the terms of Section 203 of the Delaware General Corporation Law, Whitney and its affiliates shall not be deemed at any time and without regard to the percentage of voting stock of the Corporation owned by Whitney or any of its affiliates, as applicable, to be an “interested stockholder” as such term is defined in Section 203(c)(5) of the Delaware General Corporation Law.

ARTICLE FIFTEEN

Whenever a compromise or arrangement is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of the Corporation or any creditor or stockholder thereof or on the application of a receiver or receivers appointed for the Corporation under the provisions of Section 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under the provisions of Section 279 of Title 8 of the Delaware Code, order a meeting of the creditors, and/or the shareholders or class of stockholders of the Corporation, as the case may be, to be summoned in such manner as the said court directs.  If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of the Corporation as a consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders, or class of stockholders, of the Corporation, as the case may be, and also on this Corporation.
