Subordinated Debt Securities due February 14, 2017

UNDERWRITING AGREEMENT

Ladies and Gentlemen:

Chittenden Corporation, a Vermont corporation (the “Company”), proposes to issue and sell $125,000,000 aggregate principal amount of its Subordinated Debt Securities due February 14, 2017 (the “Notes”) to the several Underwriters named in Schedule A hereto (collectively the “Underwriters,”), for whom Lehman Brothers Inc. is acting as Representative (in such capacity, the “Representative”). The Notes will be issued pursuant to an Indenture dated as of February 14, 2007 (the “Indenture”) between the Company and The Bank of New York Trust Company, N.A., a national banking association, as Trustee (the “Trustee”). This agreement (this “Agreement”) is to confirm the agreement concerning the purchase of the Notes from the Company by the Underwriters.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a shelf registration statement on Form S-3 (No. 333-87586), as amended by Pre-effective Amendment No. 1 thereto, covering the registration of the Notes under the Securities Act of 1933, as amended (the “1933 Act”), which permits the delayed or continuous offering of securities pursuant to Rule 415 of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus (including a prospectus supplement relating to the Notes) in accordance with the provisions of Rule 430B (“Rule 430B”) of the 1933 Act Regulations and paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations. Any 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 Rule 430B is referred to as “Rule 430B Information.” The term “preliminary prospectus” means a preliminary prospectus supplement specifically relating to the Notes together with a base prospectus. Such registration statement, at any given time, including the exhibits thereto, schedules thereto, if any, and the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act at such time, and information (including the Rule 430B Information) otherwise deemed to be part thereof or included thereon by 1933 Act Regulations at such time, 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, including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, in the form first furnished to the Underwriters for use in connection with the offering of the Notes 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”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “1934 Act”) which is incorporated by reference in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be.

6

result in any violation (in each case material to the Company and its subsidiaries considered as a whole) of any statute or any order, rule or regulation of any court or regulatory authority or other governmental body having jurisdiction over the Company or any of its subsidiaries or any of their properties; and no consent, approval, license, registration, decree, authorization or order of, or filing or qualification with, any court or governmental body or agency is required for, and the absence of which would materially affect, the performance by the Company of its obligations under this Agreement, in connection with the offering, issuance or sale of the Notes hereunder or the consummation of the transactions contemplated by this Agreement or for the due execution, delivery or performance of the Indenture by the Company, except such as have already been obtained or as may be required under the 1933 Act, the 1934 Act or the state securities laws of the various states in connection with the sale of the Notes and except for the qualification of the Indenture under the 1939 Act.

7

except where lack thereof would not result in a Material Adverse Effect, and the Company and its subsidiaries have not received any written notice of any infringement of or conflict with asserted rights of others with respect to any patent or proprietary rights or of any facts or circumstances which would render any patent and proprietary rights invalid or inadequate to protect the interest of the Company and 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 any Material Adverse Effect.

(xviii) 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 for such Governmental Licenses the absence of which would not reasonably be expected to cause 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 reasonably be expected to, singly or in the aggregate, have 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 have 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.

(xix) Manipulation. The Company and its subsidiaries have not taken and will not take, directly or indirectly, any action designed to or which constituted or which might reasonably be expected to cause or result in stabilization or manipulation of the price of the Notes.

(xxii) 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 that are material to the business of the Company and its subsidiaries, considered as one enterprise, 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 Disclosure Package and the Prospectus or (b) do not, singly or in the aggregate,

8

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 described in the Disclosure Package and the Prospectus, are in full force and effect, and neither the Company nor any subsidiary has received 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.

(xxiii) Compliance with the Sarbanes-Oxley Act. There is, and has been, no failure on the part of the Company or, to the knowledge of the Company, any of the Company’s directors or officers, in their capacities as such, to comply with the provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith, except for such failures to comply that would not individually or in the aggregate reasonably be expected to have a Material Adverse Effect.

(xxiv) Internal Control Over Financial Reporting. Each of the Company and its subsidiaries maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company’s internal control over financial reporting is effective, and the Company is not aware of any material weaknesses in its internal control over financial reporting.

(xxv) Disclosure Control and Procedures. The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) that comply with the requirements of the Exchange Act; and such disclosure controls and procedures have been designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is communicated to the Company’s principal executive officer and principal financial officer by others within those entities to allow timely decisions regarding disclosure.

(b) Officers’ Certificates. Any certificate signed by any officer of the Company delivered to the Underwriters or to counsel for the Underwriters shall be deemed a representation and warranty by the Company, to each Underwriter as to the matters covered thereby on the date of such certificate and, unless subsequently amended or supplemented, at each Representation Date subsequent thereto.

SECTION 2. Sale and Delivery to Underwriters; Closing

(a) Notes. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company the principal amount of Notes set forth in Schedule A opposite the name of such Underwriter plus any additional principal amount which such Underwriter may be obligated to purchase pursuant to Section 11 hereto, at a price equal to 99.234% of the principal amount thereof, plus accrued interest, if any, from February 14, 2007.

(b) Delivery and Payment for the Notes. Delivery of the Notes shall be made at the offices of Sidley Austin LLP, 787 Seventh Ave, New York, New York 10019, at 10:00 A.M.

It is understood that each Underwriter has authorized the Representative, for its account, to accept delivery of, receipt for, and make payment of the purchase price for the principal amount of Notes which it has agreed to purchase. Lehman Brothers, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Notes to be purchased by any Underwriter whose funds have not been received by the Closing Time, but such payment shall not relieve such Underwriter from its obligations hereunder.

The Company, subject to Section 3(b), will comply with the requirements of Rule 424 or Rule 430B, as applicable, and will notify the Underwriters as promptly as practicable, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or any supplement to the Prospectus or any amended Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, any prospectus, or of the suspension of the qualification of the Notes for offering or sale in any jurisdiction or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Notes. The Company will effect the filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest practicable moment.

10

(b) Filing of Amendments; Preparation of Final Term Sheet. Until the distribution of the Notes is complete, the Company will give the Representative notice of their intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)), or any amendment, supplement or revision to either any preliminary prospectus or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, and the Company will furnish the Representative with copies of any such documents to, and consult with, the Representative and its counsel within a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representative or counsel for the Representative shall reasonably object in writing.

(c) Delivery of Registration Statements. The Company has furnished or will deliver to the Representative and counsel for the Representative, without charge, as many signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and, upon request, documents incorporated or deemed to be incorporated by reference therein) as it may reasonably request, and will also deliver to the Representative, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits). The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

11

hereof, such Prospectus shall be furnished at the expense of such Underwriter. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Notes as contemplated in this Agreement and in the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Notes, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters and for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f) Blue Sky Qualifications. The Company will use its best efforts, when and as reasonably requested by counsel for the Underwriters, to qualify the Notes for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Underwriters may designate and to maintain such qualifications in effect for as long as may be required to complete the distribution of Notes contemplated hereby; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(g) Rule 158. The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(h) DTC. The Company will cooperate with the Underwriters and use their commercially reasonable efforts to permit the Notes to be eligible for clearance and settlement through the facilities of The Depository Trust Company.

(i) Use of Proceeds. The Company will use the proceeds referred to in the Disclosure Package and the Prospectus under “Use of Proceeds” in the manner described therein.

(j) Restriction on Sale of the Notes. During a period of 30 days from the date of the Prospectus, the Company will not, without the prior written consent of the Representative,

12

directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any Notes (or debt securities substantially similar to the Notes), or any security convertible into or exchangeable into or exercisable for the Notes. The foregoing sentence shall not apply to the Notes to be sold hereunder.

Subject to the last sentence of this Section 4(a), and except as set forth in Sections 7 and 8 hereof, the Company will pay all expenses incident to the performance of its obligations under this Agreement, including (i) the preparation, printing and filing of the Registration Statement (including financial statements and exhibits) as originally filed and of each amendment thereto, (ii) the preparation, printing and delivery to the Underwriters of this Agreement, any Agreement among Underwriters and such other documents as may be required in connection with the offering, purchase, sale, issuance or delivery of the Notes (not including any fees or disbursements of counsel for the Underwriters), (iii) the preparation, issuance and delivery of the certificates for the Notes to the Underwriters, including any transfer taxes and any stamp or other duties payable upon the sale, issuance or delivery of the Notes to the Underwriters, (iv) the fees and disbursements of the Company’s counsel, accountants and other advisors, (v) the qualification of the Notes under securities laws in accordance with the provisions of Section 3(f) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection therewith and in connection with the preparation of the Blue Sky Survey and any supplement thereto, if any, (vi) the printing and delivery to the Underwriters of copies of each preliminary prospectus, any Issuer Free Writing Prospectus and the Prospectus and any amendments or supplements thereto, (vii) the printing and delivery to the Underwriters of copies of the Blue Sky Survey and any supplement thereto, if any, (viii) the fees and expenses of the Trustee and any transfer agent or registrar for the Notes, (ix) any fees payable in connection with the rating of the Notes and (x) the cost and charges associated with the approval of the Notes by The Depository Trust Company for “book-entry” transfer.

(b) Termination of Agreement. If this Agreement is terminated by the Underwriters in accordance with the provisions of Section 6 or Section 10(a)(i) hereof, the Company shall reimburse the Underwriters for all of their out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriters.

SECTION 5. Free Writing Prospectuses.

(a) Company’s Representation. The Company represents and warrants to, and agrees with, each Underwriter that (i) the Company has not made, and will not, make any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus without the prior consent of the Representative (which consent being deemed to have been given with respect to (A) the Final

13

Term Sheet prepared and filed pursuant to Section 3(b) hereof and (B) any other Issuer Free Writing Prospectus identified on Schedule B hereto); (ii) each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the 1933 Act and the 1933 Act Regulations on the date of first use, and the Company has complied with any filing requirements applicable to such Issuer Free Writing Prospectus pursuant to Rule 433 of the 1933 Act Regulations; (iii) each Issuer Free Writing Prospectus will not, as of its issue date and through the time the Notes are delivered pursuant to Section 2 hereof, include any information that conflicts with the information contained in the Registration Statement, any preliminary prospectus and the Prospectus; and (iv) each Issuer Free Writing Prospectus, when considered together with the information contained in the preliminary prospectus, did not, as of the Applicable Time, does not, as of the date hereof, and will not, as of the Closing Time, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(b) Underwriter’s Representation. Each Underwriter represents and warrants to, and agrees with, the Company and each other Underwriter that it has not made, and will not make any offer relating to the Notes that would constitute a “free writing prospectus” (as defined in Rule 405 of the 1933 Act Regulations) required to be filed with the Commission, without the prior consent of the Company and the Representative.

(c) Errors or Omissions. The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the preliminary prospectus or the Prospectus or would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Representative and, if requested by the Representative, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission.

SECTION 6. Conditions of Underwriters’ Obligations. The obligations of the several Underwriters hereunder are subject to the accuracy, as of the date hereof and the Closing Time (as if made at the Closing Time), of the representations and warranties of the Company contained herein or in certificates of any officer of the Company delivered pursuant to the provisions hereof, to the performance by the Company of its covenants and other obligations hereunder and to the following further conditions:

SECTION 7. Indemnification.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter 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) 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, any Issuer Free Writing Prospectus, the Disclosure Package 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;

16

(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 to the extent based upon any such untrue statement or omission, or any such alleged untrue statement or omission, provided that (subject to Section 7(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 one counsel for the Underwriters (in addition to local counsel) chosen by the Representative), 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 or on behalf of any Underwriter through Lehman Brothers expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430B information, or any preliminary prospectus, any Issuer Free Writing Prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, the Company’s directors, each of the Company’s 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 against any and all loss, liability, claim, damage and expense whatsoever 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 430B Information, or any preliminary prospectus, any Issuer Free Writing Prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Underwriter through Lehman Brothers expressly for use in the Registration Statement (or any amendment thereto) or any preliminary prospectus, Issuer Free Writing Prospectus or Prospectus (or any amendment or supplement thereto).

17

(c) Actions against Parties; Notification. Each indemnified party shall give prompt notice 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 7(a) above, counsel to the indemnified parties shall be selected by Lehman Brothers, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Company, in each case reasonably acceptable to the indemnifying party. 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 7 or Section 8 hereof (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.

(d) 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, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(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; provided that an indemnifying party shall not be liable for any such settlement effected without its consent if such indemnifying party, prior to the date of such settlement (1) reimburses such indemnified party in accordance with such request for the amount of such fees and expenses of counsel as the indemnifying party believes in good faith to be reasonable and (2) provides written notice to the indemnified party that the indemnifying party disputes in good faith the reasonableness of the unpaid balance of such fees and expenses.

SECTION 8. Contribution. If the indemnification provided for in Section 7 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

18

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 on the one hand and the Underwriters on the other hand from the offering of the Notes 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 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 on the one hand and the Underwriters 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 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 Notes as set forth on such cover.

The relative fault of the Company 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 by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 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 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 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 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes 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.

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.

19

For purposes of this Section 8, 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 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 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. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the principal amount of Notes set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 9. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its other subsidiaries 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 controlling person, or by or on behalf of the Company, and shall survive delivery of the Notes to the Underwriters.

SECTION 10. Termination.

(a) Termination; General. The Representative may terminate this Agreement, by notice to the Company, 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 preliminary prospectus, Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings or business affairs of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, (ii) if there has occurred any outbreak of hostilities or escalation thereof or other national or international calamity or crisis (including, without limitation, an act of terrorism) or any change in national or international political, financial or economic conditions, in each case the effect of which on the financial markets in the United States is so material and adverse so as to make it, in the judgment of the Representative, impracticable or inadvisable to market the Notes or to enforce contracts for the sale of the Notes, (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, 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 a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or (iv) if a banking moratorium has been declared by either Federal, New York or Vermont 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, 7 and 8 shall survive such termination and remain in full force and effect.

SECTION 11. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time to purchase the Notes which it or they are obligated to

20

purchase under this Agreement (the “Defaulted Securities”), the Representative 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 herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

(a) if the principal amount of Defaulted Securities does not exceed 10% of the principal amount of Notes 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 principal amount of Defaulted Securities exceeds 10% of the principal amount of Notes to be purchased on such date, this Agreement 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, either the Representative or the Company shall have the right to postpone Closing Time 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 11.

SECTION 12. 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 Representative shall be directed to Lehman Brothers at Lehman Brothers Inc., 745 Seventh Avenue, New York, New York 10019, attention of Debt Capital Markets, Financial Institutions Group (with a copy to the General Counsel); notices to the Company shall be directed to it at Chittenden Corporation, Two Burlington Square, Burlington, Vermont 05401, attention of F. Sheldon Prentice, Senior Vice President, General Counsel and Corporate Secretary (with a copy to William Mayer, Esq., Goodwin Procter LLP, Exchange Place, Boston, MA 02109).

SECTION 13. Parties. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company 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 their respective successors and the controlling persons and officers and directors referred to in Sections 7 and 8 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 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 purchaser of Notes from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

21

SECTION 14. Governing Law and Time. This agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflicts of law. Specified times of day refer to New York City Time.

SECTION 15. Information Furnished by Underwriters. The Underwriters severally confirm that the information appearing in the list of names of each of the Underwriters under the caption “Underwriting” in the most recent preliminary prospectus and the Prospectus and the statements in the fourth, eighth, ninth and tenth paragraphs and the third sentence of the fourteenth paragraph under the caption “Underwriting” in the most recent Preliminary Prospectus and the Prospectus, constitute the only written information furnished to the Company by the Representative on behalf of the Underwriters, referred to in Sections 1(a)(i), 7(a) and 7(b) of this Agreement.

SECTION 16. Research Analyst Independence. The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering of the Notes that differ from the views of their respective investment banking divisions. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

SECTION 17. Nature of Relationship. The Company acknowledges and agrees that in connection with the offering and the sale of the Notes or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriters, on the other hand, exists; (ii) the Underwriters are not acting as advisors, experts or otherwise, to the Company, including, without limitation, with respect to the determination of the public offering price of the Notes, and such relationship between the Company, on the one hand, and the Underwriters, on the other hand, is entirely and solely a commercial relationship, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

SECTION 18. Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.
