In addition, such termination shall be subject to Section 4 hereof, and Sections 1, 7 and 8 hereof shall survive any such termination and remain in full force and effect.

(a)     Offer and Sale Procedures.  The Placement Agent and the Offerors hereby establish and agree to observe the following provisions with respect to the offer and sale of the Capital Securities:

(i)     Offers and Sales only to the Purchaser.  Offers and sales of the Capital Securities will be made only to the Purchaser in a transaction not requiring registration under the 1933 Act.

(ii)     No General Solicitation.  No general solicitation or general advertising (within the meaning of Rule 502(c) under the 1933 Act) has been or will be used in connection with the offer and sale of the Capital Securities.

(iii)     No Directed Selling Efforts.  No directed selling efforts (within the meaning of Regulation S) has been or will be used with respect to the offer and sale of the Capital Securities.

(iv)     Purchaser Notification.

(b)     Covenants of the Offerors.  Each of the Offerors, jointly and severally, covenant with the Placement Agent and the Purchaser as follows:

(i)     Due Diligence.  In connection with the initial purchase of the Capital Securities, the Offerors agree that, prior to the Representation and Delivery Date, the Placement Agent and the Purchaser shall have the right to make reasonable inquiries into the business of the Trust, the Company and the subsidiaries of the Company.  The Offerors also agree to provide answers to the Placement Agent and the Purchaser, if requested, concerning the Trust, the Company and the subsidiaries of the Company (to the extent that such information is

13

available or can be acquired and made available without unreasonable effort or expense and to the extent the provision thereof is not prohibited by applicable law) and the terms and conditions of the offering of the Capital Securities and the Subordinated Debt Securities.

(ii)     Integration.  The Offerors agree that they will not, and will cause their Affiliates not to, make any offer or sale of securities of the Offerors of any class if, as a result of the doctrine of "integration" referred to in Rule 502 under the 1933 Act, such offer or sale would render invalid the exemption from the registration requirements of the 1933 Act provided by Section 4(2) thereof or by Rule 144A or otherwise.

(iii)     Restriction on Repurchases.  Until the expiration of two (2) years (or such shorter or longer period as permitted or required by Rule 144(k) under the 1933 Act  (or similar successor rule)) after the original issuance of the Capital Securities, the Offerors will not, and will cause their Affiliates not to, purchase or agree to purchase or otherwise acquire any Capital Securities which are "restricted securities" (as such term is defined under Rule 144(a)(3) under the 1933 Act), whether as beneficial owner or otherwise, unless, immediately upon any such purchase, the Offerors or any Affiliate shall submit such Capital Securities to the Institutional Trustee for cancellation.

(a)     Indemnification of the Placement Agent and the Purchaser.  Each of the Offerors agree, jointly and severally, to indemnify and hold harmless: (x) the Placement Agent, and the Purchaser, (y) each person, if any, who controls (within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act) the Placement Agent or the Purchaser (each such person, a "controlling person") and (z) the respective partners, directors, officers, employees and agents of the Placement Agent and the Purchaser or any such controlling person, as follows:

(i)     against any and all loss, liability, claim, damage and expense whatsoever, as incurred, relating to or arising out of, or based upon, in whole or in part, (A) any untrue statement or alleged untrue statement of a material fact included in the 1934 Act Reports, 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; (B) any untrue statement or alleged untrue statement of material fact contained in any information (whether written or oral) or documents executed in favor of or furnished or made available to the Placement Agent or the Purchaser by the Offerors; (C) any omission or alleged omission to state in any information (whether written or oral) or documents executed in favor of or furnished or made available to the Placement Agent or the Purchaser by the Offerors a material fact necessary to make the statements therein not misleading; or (D) the breach or alleged breach of any representation, warranty and agreement of any Offeror contained herein or in the Subscription Agreement;

(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, or breach or alleged breach of any such

14

representation, warranty or agreement; provided, that (subject to Section 7(c) hereof) any such settlement is effected with the written consent of the Offerors; and

(iii)    against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Placement Agent), 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, or breach or alleged breach of any such representation, warranty or agreement, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that the Company agrees to indemnify and hold harmless the Trust against any and all loss, liability, claim, damage and expense whatsoever, as incurred, which is due from the Trust pursuant to the
foregoing.

(b)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.  Counsel to the indemnified parties shall be selected by the Placement Agent.  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.

(c)     Settlement without Consent if Failure to Reimburse.  If at any time an indemnified party shall have validly 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

15

accordance with such request prior to the date of such settlement, provided, however, that an indemnifying party shall not be liable for any such settlement effected without its consent if such indemnifying party (1) reimburses such indemnified party with respect to those fees and expenses of counsel that it determines in good faith are reasonable and (2) provides written notice within 10 days after receipt of the request for reimbursement to the indemnified party substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement.

SECTION 8.  Contribution.  In order to provide for just and equitable contribution in circumstances under which the indemnification provided for in Section 7 hereof is for any reason held to be unenforceable for the benefit of 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 Offerors, on the one hand, and the Placement Agent, on the other hand, from the offer and sale of the Capital 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 Offerors, on the one hand, and the Placement Agent, on the other hand, in connection with the statements, omissions or breaches which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Offerors, on the one hand, and the Placement Agent, on the other hand, in connection with the offer and sale of the Capital Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the sale of the Capital Securities pursuant to this Agreement (before deducting expenses) received by the Offerors and the total commission received by the Placement Agent bear to the aggregate of such net proceeds and commissions.

The Offerors and the Placement Agent agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation 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, omission or alleged omission or breach or alleged breach.

Notwithstanding the provisions of this Section 8, the Placement Agent shall not be required to contribute any amount in excess of the total commissions received by it.

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.

16

For purposes of this Section 8, the Purchaser, each person, if any, who controls the Placement Agent or the Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Actand the respective partners, directors, officers, employees and agents of the Placement Agent, the Purchaser or any such controlling person shall have the same rights to contribution as the Placement Agent, while each officer and director of the Company, each Trustee of the Trust 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 Offerors.

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 Trustees of the Trust submitted pursuant hereto shall remain operative and in full force and effect, and shall survive delivery of the Capital Securities by the Trust.

SECTION 10.  Termination of Agreement.

(a)     Termination; General.  The Placement Agent may terminate this Agreement, by notice to the Offerors, at any time on or prior to the Closing Date if, since the time of execution of this Agreement or, in the case of (i), since the respective dates as of which information is given in the 1934 Act Reports, (i) there has occurred any Material Adverse Effect, or (ii) there has occurred any material adverse change in the financial markets in the United States, any outbreak of hostilities or escalation thereof or any other calamity or crisis, or any change or development involving political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Placement Agent, impracticable to market the Capital Securities or to enforce contracts for the sale of the Capital Securities, or (iii) trading in any securities of the Company has been suspended or limited by the Commission or any national stock exchange or market on or in which such securities are traded or quoted, or if trading generally on the American Stock Exchange, the New York Stock Exchange or the Nasdaq National Market has been suspended or 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 or any other governmental authority, or (iv) a banking moratorium has been declared by United States federal, Delaware, Maine 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 and Section 5 hereof, and provided further that Sections 1, 7 and 8 hereof shall survive such termination and remain in full force and effect.

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.

ANNEX C

Pursuant to Section 5(c) of the Placement Agreement, special tax counsel for the Offerors shall deliver an opinion in substantially the following form:

We have acted as special tax counsel to Northeast Bancorp, a Maine corporation (the "Company"), in connection with the offering by NBN Capital Trust IV (the "Trust") of 10,000 MMCapSSM (liquidation amount $1,000 per capital security) (the "Capital Securities").  This opinion letter is furnished pursuant to Section 5(c) of the Placement Agreement, dated December 17, between the Company, the Trust and you.

In arriving at the opinions expressed below we have examined executed copies of (i) the Amended and Restated Declaration of Trust of the Trust dated the date hereof (the "Declaration"), and (ii) the Indenture relating to the issuance of the Fixed/Floating Rate Junior Subordinated Debt Securities due 2035 (the "Subordinated Debt Securities"), dated as of the date hereof (the "Indenture") (together, the "Operative Documents").  In addition, we have made such investigations of law and fact as we have deemed appropriate as a basis for the opinion expressed below.

It is our opinion that, under current law and assuming the performance of the Operative Documents in accordance with the terms described therein, the Subordinated Debt Securities will be treated for United States federal income tax purposes as indebtedness of the Company.

It is our opinion that the Trust will be classified for United States federal income tax purposes as a grantor trust and not as an association taxable as a corporation.

Our opinion is based on the U.S. Internal Revenue Code of 1986, as amended, Treasury regulations promulgated thereunder, and administrative and judicial interpretations thereof, all as of the date hereof and all of which are subject to change, possibly on a retroactive basis.  In rendering this opinion, we are expressing our views only as to the federal income tax laws of the United States of America.
