If any event shall occur or condition shall exist as a result of which it is necessary (or, if the Representatives or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend the Registration Statement or amend or supplement the General Disclosure Package, the Prospectus in order that the Registration Statement, the General Disclosure Package and the Prospectus, as the case may be, 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 1933 Act Rules and Regulations, the 1934 Act or the 1934 Act Rules and Regulations, the Company will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement (or, if the Representatives or counsel for the Underwriters shall have notified the Company as aforesaid, the Company will promptly notify the Representatives of its intention to prepare such amendment or supplement) and will promptly prepare and file with the Commission, subject to Section 3(a)(2), such amendment or supplement as may be necessary to correct such untrue statement or omission or to comply with such requirements, and, in the case of an amendment or post-effective amendment to the Registration Statement, the Company will use its best efforts to have such amendment declared or become effective as soon as practicable, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(6)Blue Sky Qualifications. The Company will use its commercially reasonable efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale, or to obtain an exemption for the Securities to be offered and sold, under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications and exemptions in effect for so long as required for the distribution of the Securities (but in no event for less than one year from the date of this Agreement); 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. In each jurisdiction in which the Securities have been so qualified or exempt, the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification or exemption, as the case may be, in effect for so long as required for the distribution of the Securities (but in no event for less than one year from the date of this Agreement).

(13)Regulated Investment Company Status. The Company will maintain its qualification as a “regulated investment company” under Subchapter M of the Code for so long as the Company remains a BDC regulated under the 1940 Act.

(14)Business Development Company Status. The Company, during a period of two years from the Effective Date of the Registration Statement, will use its best reasonable efforts to maintain its status as a BDC; provided, however, the Company may change the nature of its business so as to cease to be, or to withdraw its election as, a BDC, with the approval of the board of directors and a vote of stockholders as required by Section 58 of the 1940 Act or any successor provision.

(2)Stabilization. The Company, the Adviser and the Administrator will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the 1934 Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(3)Best Efforts. The Company, the Adviser and the Administrator will use their best reasonable efforts to discharge all conditions of theirs to closing as set forth in this Agreement and with respect to the Company, to perform all of the agreements required of them by this Agreement.

SECTION 6.Indemnification.

(a)The Company, the Adviser and the Administrator, jointly and severally, agree to indemnify and hold harmless each Underwriter, its affiliates 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:

30

(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 for the Securities as originally filed or in any amendment thereof (and including any post-effective amendment, any Rule 462(b) Registration Statement and any Rule 430C Information deemed to be included or incorporated therein), or in any preliminary prospectus, the Prospectus, the Disclosure Package or in any sales material (or any amendment or supplement to any of the foregoing), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading;

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

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

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), or the General Disclosure Package, any preliminary prospectus 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 following information in the Prospectus furnished on behalf of each Underwriter: (i) their names, (ii) the figure appearing in the first sentence of the second paragraph of text under the caption “Underwriting—Option” and (iii) the second paragraph under the caption “Underwriting—Sales Outside the United States.”

(b)Each Underwriter severally agrees to indemnify and hold harmless the Company, the Adviser and the Administrator, each of their directors, each of the Company’s officers who signed the Registration Statement, and each person, if any, who controls the Company, the Adviser or the Administrator within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 6, 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), or the General Disclosure Package, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), in reliance

31

upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: (i) their names, (ii) the figure appearing in the first sentence of the second paragraph of text under the caption “Underwriting—Option” and (iii) the second paragraph under the caption “Underwriting—Sales Outside the United States.”

(c)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 as follows: counsel to the Underwriters 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 shall be selected by the Representatives; and counsel to the Company, the Adviser, the Administrator, each of their directors, each of the Company’s officers who signed the Registration Statement and each person, if any, who controls the Company, the Adviser or the Administrator within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall be selected by the Company, the Adviser and the Administrator. 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 the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Underwriters 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, and the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Company, the Adviser, the Administrator, each of their directors, each of the Company’s officers who signed the Registration Statement and each person, if any, who controls the Company, the Adviser or the Administrator within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, in each case 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)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) effected without its written consent if (i) such settlement is entered into more than 45 days after

32

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.

(e)The provisions of this Section 6 and in Section 7 hereof shall not affect any agreements among the Company, the Adviser and the Administrator with respect to indemnification of each other or contribution between themselves.

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, the Adviser and the Administrator on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, the Adviser and the Administrator 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, the Adviser and the Administrator (treated jointly for this purpose as one person) on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, the Adviser and the Administrator (treated jointly for this purpose as one person) and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Securities as set forth on such cover.

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

The Company, the Adviser, the Administrator 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

33

investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

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 of the Company, the Adviser or the Administrator, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company, the Adviser or the Administrator 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 Adviser and the Administrator. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Exhibit A hereto and not joint.

SECTION 8.Representations, Warranties and Agreements to Survive Delivery.

SECTION 9.Termination of Agreement.

(a)The Representatives may terminate this Agreement, by notice to the Company, the Adviser and the Administrator, at any time on or prior to the Closing Date (and, if any Option Securities are to be purchased on an Option Closing Date which occurs after the Closing Date, the Representatives may terminate the obligations of the several Underwriters to purchase such Option Securities, by notice to the Company, at any time on or prior to such Option Closing Date) (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus or the General Disclosure Package, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus or the General Disclosure Package, any material adverse change in the condition, financial or otherwise, or in the business affairs or business prospects of the Adviser or the

34

Administrator, whether or not arising in the ordinary course of business, or (iii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iv) if trading in any securities of the Company has been suspended or limited by the Commission or The Nasdaq Global Select Market, or if trading generally on the New York Stock Exchange or The Nasdaq Global Select 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 order of the Commission, FINRA 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 (v) if a banking moratorium has been declared by either federal or New York authorities, or (vi) if there shall have occurred any downgrading, or any notice or announcement shall have been given or made of: (A) any intended or potential downgrading or (B) any watch, review or possible change that does not indicate an affirmation or improvement in the rating accorded any securities of or guaranteed by the Company or any of its subsidiaries by any “nationally recognized statistical rating organization,” as that term is defined in Section 3(a)(62) under the 1934 Act, or (vii) if an outbreak or escalation of hostilities involving the United States or a declaration by the United States of a national emergency or war has occurred or (viii) if any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere has occurred, if the effect of any such event specified in clause (vii) or (viii) in your judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities being delivered at such Closing Date or Option Closing Date on the terms and in the manner contemplated in the General Disclosure Package and the Prospectus.

(b)Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and except that, in the case of any termination of this Agreement, Sections 1, 6, 7, 8 and 17 hereof shall survive such termination and remain in full force and effect and except that, in the case of the termination of the obligations of the several Underwriters to purchase any Option Securities on an Option Closing Date which occurs after the Closing Date, this Agreement shall otherwise survive such termination and remain in full force and effect.

SECTION 10.Default by One or More of the Underwriters. If one or more of the Underwriters shall fail on the Closing Date or an Option Closing Date to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

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

35

their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

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

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

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

In order to induce you and the other Underwriters to enter into the Underwriting Agreement, and in light of the benefits that the offering of the Common Stock will confer upon the undersigned in its capacity as a securityholder and/or an officer, director or employee of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each Underwriter that, during the period beginning on and including the date of the Underwriting Agreement through and including the date that is the 45th day after the date of the Underwriting Agreement, the undersigned will not, without the prior written consent of Wells Fargo, Merrill Lynch and UBS directly or indirectly:

(i) 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, lend or otherwise transfer or dispose of any shares of the Company’s Common Stock or preferred stock or other capital stock (collectively, “Capital Stock”) or any securities convertible into or exercisable or exchangeable for Common Stock or other Capital Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or

(ii) enter into any swap or other agreement, arrangement or transaction that transfers to another, in whole or in part, directly or indirectly, any of the economic consequences of ownership of any Common Stock or other Capital Stock or any securities convertible into or exercisable or exchangeable for any Common Stock or other Capital Stock,

whether any transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock, other Capital Stock, other securities, in cash or otherwise. Moreover, if:

(1) during the last 17 days of such 45-day restricted 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 such 45-day restricted period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of such 45-day restricted period,

the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the date of issuance of the earnings release or the occurrence of the material news or material event, as the case may be, unless Wells Fargo, Merrill Lynch and UBS waive, in writing, such extension.

The undersigned hereby acknowledges and agrees that written notice of any extension of the 45-day restricted period pursuant to the provisions of the previous paragraph will be delivered by Wells Fargo, Merrill Lynch and UBS to the Company, the Adviser or the Administrator and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this agreement during the period from and including the date of this agreement through and including the 34^th day following the expiration of the 45-day restricted period, the undersigned will give prior notice thereof to the Company and will not consummate any such transaction or take any such action unless it has received written confirmation from the Company that such restricted period (as the same may have been extended pursuant to the previous paragraph) has expired.

Notwithstanding the provisions set forth in the second preceding paragraph, the undersigned may, without the prior written consent of Wells Fargo, Merrill Lynch and UBS, transfer any Common Stock or other Capital Stock or any securities convertible into or exchangeable or exercisable for Common Stock or other Capital Stock

(1) if the undersigned is a natural person, as a bona fide gift or gifts, or by will or intestacy, or as may be required by court order or by action of law, to any member of the immediate family (as defined below) of the undersigned or to a trust the beneficiaries of which are exclusively the undersigned or members of the undersigned’s immediate family, or as a bona fide gift or gifts to a charity or educational institution,

Exh. D-2

(2) if the undersigned is a partnership or a limited liability company, to a partner or member, as the case may be, of such partnership or limited liability company if, in any such case, such transfer is not for value, and

(3) if the undersigned is a trust, to a beneficiary of such trust if such transfer is not for value,

provided, however, that in the case of any transfer described in clause (1) or (2) above, it shall be a condition to the transfer that (A) the transferee executes and delivers to Wells Fargo, Merrill Lynch and UBS, acting on behalf of the Underwriters, not later than one business day prior to such transfer, a written agreement, in substantially the form of this agreement (it being understood that any references to “immediate family” in the agreement executed by such transferee shall expressly refer only to the immediate family of the undersigned and not to the immediate family of the transferee) and otherwise satisfactory in form and substance to Wells Fargo, Merrill Lynch and UBS, and (B) such transfer is not reported or required to be reported in any public report or filing with the Securities and Exchange Commission or otherwise, and the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfer during such 45-day restricted period (as the same may be extended as described above). For purposes of this paragraph, “immediate family” shall mean a spouse, child, grandchild or other lineal descendant (including by adoption), father, mother, brother or sister of the undersigned.

The undersigned further agrees that (i) it will not, during such 45-day restricted period (as the same may be extended as described above), make any demand or request for or exercise any right with respect to the registration under the 1933 Act, of any Common Stock or other Capital Stock or any securities convertible into or exercisable or exchangeable for Common Stock or other Capital Stock, and (ii) the Company may, with respect to any Common Stock or other Capital Stock or any securities convertible into or exercisable or exchangeable for Common Stock or other Capital Stock owned or held (of record or beneficially) by the undersigned, cause the transfer agent or other registrar to enter stop transfer instructions and implement stop transfer procedures with respect to such securities during such 45-day restricted period (as the same may be extended as described above).

Notwithstanding anything herein to the contrary, this letter agreement shall not prohibit the disposition of Common Stock by the undersigned to Golub Capital Employee Grant Program Rabbi Trust upon the vesting of restricted shares of Common Stock in order to satisfy withholding and other income tax related obligations of the undersigned.

In addition, the undersigned hereby waives any and all notice requirements and rights with respect to the registration of any securities pursuant to any agreement, instrument, understanding or otherwise, including any registration rights agreement or similar agreement, to which the undersigned is a party or under which the undersigned is entitled to any right or benefit and any tag-along rights, co-sale rights or other rights to have any securities (debt or equity) included in the offering contemplated by the Underwriting Agreement or sold in connection with the sale of Common Stock pursuant to the Underwriting Agreement, provided that such waiver shall apply only to the public offering of Common Stock pursuant to the

Exh. D-3

Underwriting Agreement and each registration statement filed under the 1933 Act in connection therewith.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this agreement and that this agreement has been duly authorized (if the undersigned is not a natural person), executed and delivered by the undersigned and is a valid and binding agreement of the undersigned. This agreement and all authority herein conferred are irrevocable and shall survive the death or incapacity of the undersigned (if a natural person) and shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

The undersigned acknowledges and agrees that whether or not any public offering of Common Stock actually occurs depends on a number of factors, including market conditions.
