The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement or the Prospectus (including any amendments or supplements to the Registration Statement or the Prospectus) made in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of any Underwriter for use in the Registration Statement or the Prospectus (or any amendments or supplements to the Registration Statement or the Prospectus), it being understood and agreed that the only such information furnished to the Company in writing by the Underwriters consists of the information described in Section 6(f) below.

(iii) The Disclosure Package as of the Applicable Time does not 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 under which they were made, not misleading.

The aggregate of all pending legal or governmental proceedings to which any Main Street Entity is a party or of which any of such Main Street Entity’s property or assets is the subject which are not described in the Registration Statement, the Prospectus or the Disclosure Package, including ordinary routine litigation incidental to the business, could not reasonably be expected to have a Material Adverse Effect.

     (aa) Investments. Save for those provided in the 1940 Act, the Code and the Small Business Investment Act of 1958 and the regulations promulgated thereunder (the “SBA Regulations”), there are no material restrictions, limitations or regulations with respect to the ability of the Company or the Funds to invest their assets as described in the Disclosure Package or the Prospectus.

     (bb) Tax Law Compliance.

The method of operation of the Funds will permit it to continue to meet the requirements for qualification as an SBIC.

     (dd) SBA Debentures. The Funds are eligible to sell securities guaranteed by the SBA in the amounts and on the terms described in the Disclosure Package and the Prospectus. The Funds are not in default under the terms of any debenture which it has issued to the SBA for guaranty by the SBA or any other material monetary obligation, and no event, which with the passage of time, notice or both has occurred, which would be a default or event of default thereunder.

Section 2. Sale and Delivery to Underwriters; Closing.

     (a) Firm Shares. On the basis of the representations, warranties and covenants contained herein and subject to the terms and conditions set forth herein, 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, at the price of $14.0125 per share (representing a public offering price of $14.75 per share, less an underwriting discount of $0.7375 per share), the number of Firm Shares set forth in Schedule A opposite the name of such Underwriter, plus any additional number of Firm Shares which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof.

     (b) Option Shares. In addition, on the basis of the representations and warranties contained herein and subject to the terms and conditions set forth herein, the Company hereby grants an option to the Underwriters, severally and not jointly, to purchase up to an additional 375,000 Common Shares, at the price per share set forth in Section 2(a) above, less the per share amount of any dividend or other distribution declared by the Company, the record date of which occurs during the period from the Closing Time through the Date of Delivery (as defined below) with respect thereto. Said option may be exercised only to cover over-allotments which may be made in connection with the Offering and distribution of the Firm Shares by the Underwriters. The option granted hereby may be exercised only by written notice from Morgan Keegan, on behalf of the Underwriters, to the Company, given within a period of 30 calendar days after the date of this Agreement, setting forth the aggregate number of Option Shares to be purchased and the time and date of payment and delivery for such Option Shares. Any such time and date of delivery (the “Date of Delivery”) shall be determined by the Underwriters, but shall not be later than seven (7) full business days and no earlier than three (3) full business days after the exercise of said option, nor in any event prior to the Closing Time. If the option is exercised as to all or any portion of the Option Shares, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Shares then being purchased which the number of Firm Shares set forth in Schedule A opposite the name of such Underwriter bears to the total number of Firm Shares, subject in each case to such adjustments as Morgan Keegan in its discretion shall make to eliminate any sales or purchases of a fractional number of Option Shares plus any additional number of Option Shares which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof.

     (c) Payment. Payment of the purchase price for, and delivery of certificates, if any, for the Firm Shares shall be made at the offices of Sutherland Asbill & Brennan LLP, 1275 Pennsylvania Avenue, NW, Washington, D.C. 20004, or at such other place as shall be agreed upon by the Underwriters and the Company, at 10:00 a.m. (Eastern Standard Time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern Standard Time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten (10) business days after such date as shall be agreed upon by the Underwriters and the Company (such time and date of payment and delivery being herein

called “Closing Time”). In addition, in the event that any or all of the Option Shares are purchased by the Underwriters, payment of the purchase price for such Option Shares shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Underwriters and the Company, on the Date of Delivery as specified in the notice from the Underwriters to the Company.

     Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery to the Underwriters for the respective accounts of the Underwriters of the Shares to be purchased by them. It is understood that each Underwriter has authorized Morgan Keegan, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Firm Shares and the Option Shares, if any, which it has agreed to purchase. Morgan Keegan, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Firm Shares or the Option Shares, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

     (d) Denominations; Registration. Certificates for the Firm Shares and the Option Shares, if any, shall be in such denominations and registered in such names as the Underwriters may request in writing at least two (2) full business days before the Closing Time or the relevant Date of Delivery, as the case may be. The certificates for the Firm Shares and the Option Shares, if the Company determines to issue any such certificates, will be made available for examination and packaging by the Underwriters in Washington, D.C. no later than 10:00 a.m. (Eastern Standard Time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be. The Firm Shares and the Option Shares to be purchased hereunder shall be delivered at the Closing Time or the Date of Delivery, as the case may be, through the facilities of the Depository Trust Company or another mutually agreeable facility, against payment of the purchase price therefore in immediately available funds to the order of the Company.

Section 3. Covenants.

     The Company agrees with each Underwriter as follows:

     (a) Compliance with Securities Regulations and Commission Requests. The Company will comply with the requirements of Rule 430C, and will notify the Underwriters as soon as practicable, and, in the cases clauses (ii)-(iv) of this Section 3(a), confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or any supplement to the 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, and (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 the Prospectus, or of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings required by Rule 497 and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing

under Rule 497 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 suspending the effectiveness of the Registration Statement pursuant to Section 8(d) of the 1933 Act, and, if any such stop order is issued, to obtain the lifting thereof at the earliest possible moment.

     (b) Filing of Amendments. The Company will give the Underwriters notice of its intention to file or prepare any amendment to the Registration Statement, or any supplement or revision to either the Preliminary Prospectus or to the Prospectus, and will furnish the Underwriters with copies of any such documents 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 Underwriters or counsel for the Underwriters shall reasonably object.

     (c) Delivery of Registration Statements. The Company has furnished or will deliver to the Underwriters and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein) and signed copies of all consents and certificates of experts, and will also deliver to the Underwriters, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters. 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.

     (d) Delivery of Prospectuses. The Company has delivered to each Underwriter, without charge, as many copies of the Preliminary Prospectus (and will deliver as many copies of the Prospectus) as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to each Underwriter, without charge, during the period when the Prospectus is required to be delivered under the 1933 Act, such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. 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 so as to permit the completion of the distribution of the Shares 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 Shares, any event shall occur or condition shall exist as a result of which it is necessary, in the reasonable opinion of counsel for the Underwriters or 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, 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) Amendments or Supplements to the Disclosure Package. If there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Company will promptly notify the Underwriters so that any use of the Disclosure Package may cease until it is amended or supplemented (at the sole cost and expense of the Company).

     (g) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriters, to qualify the Shares 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 so long as required for the distribution of the Shares; provided, however, that the foregoing shall not apply to the extent that the Shares are “covered securities” that are exempt from state regulation of securities offerings pursuant to Section 18 of the 1933 Act; and provided, further, 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.

     (h) 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 security holders as soon as practicable, but in any event not later than 16 months after the date hereof, 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.

     (i) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Shares in the manner specified in the Prospectus and the Disclosure Package under “Use of Proceeds.”

     (j) Listing. The Company will use its reasonable best efforts to cause the Shares to be duly authorized for listing on the NASDAQ, prior to the date the Shares are issued.

     (k) Restriction on Sale of Shares. During a period of 60 days from the date of the Prospectus Supplement (the “Lock-Up Period”), the Company will not, without the prior written consent of Morgan Keegan (which will not be unreasonably withheld), (i) 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 Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares or file any registration statement under the 1933 Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Shares,

whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of Common Shares or such other securities, in cash or otherwise. Notwithstanding the foregoing, if (1) during the last 17 days of the Lock-Up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. The restrictions in this Section shall not apply to (A) the Shares to be sold hereunder, (B) the Common Shares issued pursuant to the Company’s Dividend Reinvestment Plan or (C) any options or Common Shares granted or withheld pursuant to the Company’s stock option, stock bonus, restricted stock or other stock plan or arrangements referred to in the Prospectus.

     (l) Reporting Requirements. The Company, during the period when the Prospectus is required to be delivered under the 1933 Act, will file all documents required to be filed with the Commission pursuant to the 1940 Act and the 1934 Act within the time periods required by the 1940 Act and the 1934 Act.

     (m) Subchapter M. The Company has elected to be taxed as a regulated investment company, and will use its best efforts to maintain qualification as a regulated investment company under Subchapter M of the Code.

     (n) No Manipulation of Market for Shares. Except for the authorization of actions permitted to be taken by the Underwriters as contemplated herein or in the Prospectus, the Company will not take, directly or indirectly, any action designed to cause or to result in, or that might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares in violation of federal or state securities laws.

     (o) Reserved

     (p) Continued Compliance with SBA Requirements. The Funds will continue to comply with the requirements for qualification as an SBIC, which is eligible to borrow from the SBA as described in the Prospectus.

The Underwriters covenant to the Company as follows:

     (q) FINRA No Objection Letter. The Underwriters agree to use their best efforts to obtain a no objection letter from FINRA regarding the fairness and reasonableness of the underwriting terms and arrangements with respect to the Offering.

Section 4. Payment of Expenses.

     (b) Termination of Agreement. If this Agreement is terminated by the Underwriters in accordance with the provisions of Section 5 or Section 9(a) hereof, the Company shall reimburse, or arrange for an affiliate to reimburse, the Underwriters for all of their out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriters.

Section 5. Conditions of Underwriters’ Obligations.

     The obligations of the Underwriters hereunder are subject to the accuracy of the representations and warranties of the Company contained in Section 1 hereof 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:

In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of Tennessee and the federal law of the United States, upon the opinions of counsel satisfactory to the Underwriters. Such counsel may also state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers of the Company and certificates of public officials.

Section 6. Indemnification.

     (a) Indemnification of Underwriters. The Company agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors, officers and employees, and any person who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and the successors and assigns of all of the foregoing persons, from and against:

(i) any and all loss, damage, expense, liability or claim whatsoever (including the reasonable cost of any investigation incurred in connection therewith) which, jointly or severally, any such Underwriter or any such person may incur under the 1933 Act, the 1934 Act, the 1940 Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (A) 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 (B) any untrue statement or alleged untrue statement of a material fact included in 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;

(ii) against any and all loss, damage, expense, liability or claim 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 arises out of or is based upon any such untrue statement or omission referred to in clause (i); 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 Morgan Keegan), reasonably incurred in investigating, preparing or defending against any actual or threatened litigation (including the fees and disbursements of counsel chosen by Morgan Keegan), 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 clauses (i) or (ii) above.

Notwithstanding the foregoing, the indemnification provisions set forth in this Section 6(a) shall not apply to any loss, damage, expense, liability or claim to the extent arising out of or based upon 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 Morgan Keegan or its counsel expressly for use in the Registration Statement (or any amendment thereto), the Disclosure Package or the Prospectus (or any amendment or supplement thereto), it being understood and agreed upon that the only such information furnished by any Underwriter consists of the information

set forth in Section 6(f) below. Moreover, that the Company will not be liable to any Underwriter with respect to the Prospectus and the Disclosure Package to the extent that the Company shall sustain the burden of proving that any such loss, damage, expense, liability or claim resulted from the fact that such Underwriter, in contravention of a requirement of this Agreement or applicable law, sold Shares to a person to whom such Underwriter failed to send or give, at or prior to the Closing Time, a copy of the Prospectus, as then amended or supplemented if: (i) the Company shall have previously furnished copies of the Prospectus (sufficiently in advance of the Closing Time to allow for distribution by the Closing Time) to the Underwriter and the loss, damage, expense, liability or claim against such Underwriter resulted from an untrue statement or omission of a material fact contained in or omitted from the Disclosure Package which was corrected in the Prospectus prior to the Closing Time and such Prospectus was required by law to be delivered at or prior to the written confirmation of sale to such person and (ii) such failure to give or send such Prospectus by the Closing Time to the party or parties asserting such loss, damage, expense, liability or claim would have constituted a defense to the claim asserted by such person.

     (b) Indemnification of the Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, officers, 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, damage, expense, liability or claim described in Section 6(a), 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), 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 such Underwriter through Morgan Keegan or its counsel expressly for use in the Registration Statement (or any amendment thereto) or the Disclosure Package or the Prospectus (or any amendment or supplement thereto), it being understood and agreed upon that the only such information furnished by any Underwriter consists of the information set forth in Section 6(f) below.

     (c) 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), counsel to the indemnified parties shall be selected by Morgan Keegan, and, in the case of parties indemnified pursuant to Section 6(b), 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 (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 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; 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.

     (e) Limitations on Indemnification. Any indemnification by the Company shall be subject to the requirements and limitations of Section 17(i) of the 1940 Act and 1940 Act Release 11330.

     (f) Information Provided By Underwriters. The Company and the Underwriters acknowledge and agree that (i) the concession and reallowance figures appearing under the caption “Underwriting—Underwriting Discounts” in the Prospectus, (ii) the statements set forth in the first sentence of each of the first and third paragraphs under the caption “Underwriting—Price Stabilization, Short Positions and Penalty Bids” in the Prospectus, (iii) the statements set forth in the first sentence under the caption “Underwriting—Passive Market Making Pursuant to Regulation M” in the Prospectus, and (iv) the list of Underwriters and their respective participation in the sale of the Shares, which is set forth in the table under the caption “Underwriting” in the Prospectus, constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Prospectus.

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 on the one hand and the Underwriters on the other hand from the offering of the Shares 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 Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the Offering of the Shares pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters (whether from the Company or otherwise), in each case as set forth on the cover of the Prospectus Supplement bear to the aggregate public offering price of the Shares 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 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.

     No Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares 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.

     Notwithstanding the provisions of this Section 7, 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 shall have the same rights to contribution as such Underwriter, and each director and officer of the Company 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 7 are several in proportion to the number of Firm Shares set forth opposite their respective names in Schedule A hereto and not joint.

     Any contribution by the Company shall be subject to the requirements and limitations of Section 17(i) of the 1940 Act and 1940 Act Release 11330.

Section 8. Representations and Warranties to Survive Delivery.

     All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company 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 Shares to the Underwriters.

Section 9. Termination of Agreement.

     (a) Termination; General. The Underwriters 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 date of the Prospectus Supplement, any Material Adverse Change 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 material outbreak of hostilities or material 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 Underwriters, impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares, or (iii) if trading in the Common Shares of the Company has been suspended or materially limited by the Commission or the NASDAQ, or if trading generally on the New York Stock Exchange 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 NASDAQ 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 or New York state 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 Section 1, Section 6, Section 7, Section 8, Section 11, Section 12 and Section 13 shall survive such termination and remain in full force and effect.

Section 10. Default by One or More of the Underwriters.

     (a) If one or more of the Underwriters shall fail at Closing Time or the Date of Delivery to purchase the Shares which it or they are obligated to purchase under this Agreement (the “Defaulted Shares”), the Underwriters 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 Shares in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Underwriters shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Shares does not exceed 10% of the number of Shares 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

(ii) if the number of Defaulted Shares exceeds 10% of the number of Shares 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 Shares to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

     (b) No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

     (c) In the event of any such default which does not result in a termination of this Agreement or, in the case of the 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 Company to sell the relevant Option Shares, as the case may be, either the Underwriters or the Company shall have the right to postpone the Closing Time or the Date of Delivery, as the case may be, for a period not exceeding seven (7) days in order to effect any required changes in the Registration Statement or Prospectus Supplement 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 13. No Fiduciary Obligation.

     The Company acknowledges and agrees that each of the Underwriters have acted, and are acting, solely in the capacity of an arm’s-length contractual counterparty to the Company with respect to the Offering of the Shares contemplated hereby (including in connection with determining the terms of the Offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, the Underwrites have not advised, and are not advising, the Company or any other person as to any legal, tax, investment, accounting or regulatory matter in any jurisdiction with respect to the transactions contemplated hereby. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions has been and will be performed solely for the benefit of the Underwriters and have not been and shall not be on behalf of the Company or any other person. It is understood that the offering price was arrived at through arm’s-length negotiations between the Underwriters and the Company, and that such price was not set or otherwise determined as a result of expert advice rendered to the Company by any Underwriter. The Company acknowledges and agrees that the Underwriters are collectively acting as an independent contractor, and any duty of the Underwriters arising out of this Agreement and the

transactions completed hereby shall be contractual in nature and expressly set forth herein. Notwithstanding anything in this Agreement to the contrary, the Company acknowledges that the Underwriters may have financial interests in the success of the Offering contemplated hereby that are not limited to the difference between the price to the public and the purchase price paid to the Company by the Underwriters for the Shares.

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 APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID STATE. UNLESS OTHERWISE EXPLICITLY PROVIDED, SPECIFIED TIMES OF DAY REFER TO ESTERN STANDARD TIME.
