(a) On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell through the Manager, as sales agent, and the Manager agrees to use its reasonable efforts to sell, as sales agent for the Company, the Shares on the following terms.

(i) The Shares are to be sold on a daily basis or otherwise as shall be agreed to by the Company and the Manager on any day that is a trading day for the Nasdaq (other than a day on which the Nasdaq is scheduled to close prior to its regular weekday closing time). The Company will designate the maximum amount of the Shares to be sold by the Manager daily as agreed to by the Manager and in any event not in excess of the amount available for issuance under the currently effective Registration Statement. Subject to the terms and conditions hereof, the Manager shall use its reasonable efforts to sell all of the Shares designated. The gross sales of the Shares sold under this Section 3(a) shall be the market price for shares of the Company’s Common Stock sold by the Manager under this Section 3(a) on the Nasdaq at the time of such sale.

(ii) Notwithstanding the foregoing, the Company may instruct the Manager by telephone (confirmed promptly by telecopy) not to sell the Shares if such sales cannot be effected at or above the price designated by the Company in any such instruction. Furthermore, the Company shall not authorize the issuance and sale of, and the Manager shall not be obligated to use its reasonable efforts to sell, any Share at a price lower than the minimum price therefor designated from time to time by the Company’s Board of Directors and notified to the Manager in writing.

(iv) The compensation to the Manager for sales of the Shares, as an agent of the Company, shall be 4% of the gross sales price of the Shares sold pursuant to this Section 3(a), and such rate of compensation shall not apply when the Manager acts as principal.

(vi) Settlement for sales of the Shares pursuant to this Section 3(a) will occur on the third business day following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Shares sold through the Manager for settlement on such date shall be issued and delivered by the Company to the Manager against payment of the Net Proceeds for the sale of such Shares. Settlement for all such Shares shall be effected by free delivery of the Shares to the Manager’s account at The Depository Trust Company in return for payments in same day funds delivered to the account designated by the Company. If the Company shall default on its obligation to deliver the Shares on any Settlement Date, the Company shall (A) hold the Manager harmless against any loss, claim or damage arising from or as a result of such default by the Company and (B) pay the Manager any commission to which it would otherwise be entitled absent such default. If the Manager breaches this Agreement by failing to deliver proceeds on any Settlement Date for the Shares delivered by the Company, the Manager will pay the Company interest based on the effective overnight Federal Funds rate.

(vii) At each Settlement Date and Filing Date (as defined below), the Company shall be deemed to have affirmed each representation and warranty contained in this Agreement. The Company covenants and agrees with the Manager that (A) with respect to each of the Company’s first three fiscal quarters, on or prior to the date on which the Company shall be obligated to file a quarterly report on Form 10-Q in respect of such quarter and (B) with respect to the Company’s fourth fiscal quarter for fiscal year 2009 and for each year thereafter, on or prior to the thirty-fifth day after the end of such quarter in which sales of the Shares were made by the Manager pursuant to this Section 3(a) (each such date, a “Filing Date”), the Company will file a prospectus supplement with the Commission under the applicable paragraph of Rule 424(b), which prospectus supplement will set forth, with regard to such quarter, the number of the Shares sold through the Manager as agent pursuant to this Section 3(a) in At the Market Offerings, the Net Proceeds to the Company and the compensation paid by the Company with respect to such sales of the Shares pursuant to this Section 3(a) and deliver such number of copies of each such prospectus supplement to the Nasdaq as are required by such exchange. Any obligation of the Manager to use its reasonable efforts to sell the Shares on behalf of the Company shall be subject to the continuing accuracy of the representations and warranties of the Company herein, to the performance by the Company of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 5 of this Agreement.

(b) (i) If the Company wishes to issue and sell the Shares other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify the Manager of the proposed terms of such Placement. If the Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Company, wishes to accept amended terms, the Manager and the Company will enter into a Terms Agreement setting forth the terms of such Placement.

(ii) The terms set forth in a Terms Agreement will not be binding on the Company or the Manager unless and until the Company and the Manager have each executed such Terms Agreement accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control.

(c) (i) Under no circumstances shall the number of the Shares sold pursuant to this Agreement and any Terms Agreement exceed the number set forth in Section 1 or the number of shares of the Common Stock available for issuance under the currently effective Registration Statement.

If any action, suit or proceeding (together, a “Proceeding”) is brought against the Manager or any such person in respect of which indemnity may be sought against the Company pursuant to the foregoing paragraph, the Manager or such person shall promptly notify the indemnifying party in writing of the institution of such Proceeding and the Company shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify the Company shall not relieve the Company from any liability which the Company may have to the Manager or any such person or otherwise except to the extent the Company was materially prejudiced by such omission. The Manager or such person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Manager or of such person unless the employment of such counsel shall have been authorized in writing by the Company in connection with the defense of such Proceeding or the Company shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to the Company (in which case the Company shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the Company, and paid as incurred (it being understood, however, that the Company shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The Company shall not be liable for any settlement of any Proceeding effected without its written consent but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless the Manager and any such person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested the Company to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, then the Company agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by the Company of the aforesaid request, (ii) the Company shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. The Company shall not, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or may be a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act, by or on behalf of such indemnified party.

(b) The Manager agrees to indemnify, defend and hold harmless the Company, its directors and officers, and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Company or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in and, in conformity with information furnished in writing by or on behalf of the Manager to the Company expressly for use with reference to the Manager in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information furnished in writing by or on behalf of the Manager to the Company expressly for use in, a Prospectus or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

If any Proceeding is brought against the Company or any such person in respect of which indemnity may be sought against the Manager pursuant to the foregoing paragraph, the Company or such person shall promptly notify the Manager in writing of the institution of such Proceeding and the Manager shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify the Manager shall not relieve the Manager from any liability which the Manager may have to the Company or any such person or otherwise. The Company or such person shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Company or such person unless the employment of such counsel shall have been authorized in writing by the Manager in connection with the defense of such Proceeding or the Manager shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to or in conflict with those available to the Manager (in which case the Manager shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but the Manager may employ counsel and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of the Manager), in any of which events such fees and expenses shall be borne by the Manager and paid as incurred (it being understood, however, that the Manager shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The Manager shall not be liable for any settlement of any such Proceeding effected without the written consent of the Manager but if settled with the written consent of the Manager, the Manager agrees to indemnify and hold harmless the Company and any such person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested the Manager to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, then the Manager agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by the Manager of the aforesaid request, (ii) the Manager shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the Manager at least 30 days’ prior notice of its intention to settle. The Manager shall not, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding.

(c) If the indemnification provided for in this Section 6 is unavailable to an indemnified party under subsections (a) and (b) of this Section 6 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Manager, on the other hand, from the offering of the Shares or (ii) if the allocation provided by clause (i) above 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 Manager, on the other, in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Manager, on the other, shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company, and the total underwriting discounts and commissions received by the Manager, bear to the aggregate public offering price of the Shares. The relative fault of the Company, on the one hand, and of the Manager, on the other hand, shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by the Manager and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(d) The Company and the Manager agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (c) above. Notwithstanding the provisions of this Section 6, the Manager shall not be required to contribute any amount in excess of commissions received by it under the Agreement or any amount by which the total price at which the Shares sold by the Manager exceeds the amount of any damage which the Manager has otherwise been required to pay by reason of such untrue statement or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The indemnity and contribution agreements contained in this Section 6 and the covenants, warranties and representations of the Company contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Manager, its partners, directors or officers or any person (including each partner, officer or director of such person) who controls the Manager within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of the Company, its directors or officers or any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Shares. The Company and the Manager agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Company, against any of the Company’s officers or directors in connection with the issuance and sale of the Shares, or in connection with the Registration Statement, any Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

SECTION 7. Representations and Agreements to Survive Delivery. All representations, warranties and agreements of the Company herein or in certificates delivered pursuant hereto or any Terms Agreement, and the agreements of the Manager contained in Section 6 of this Agreement, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Manager or any controlling persons, or the Company (or any of their officers, directors or controlling persons), and shall survive delivery of and payment for the Shares.

SECTION 8. Termination.

(a) The Company shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Shares in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) if the Shares have been sold through the Manager for the Company, then Sections 4(i) and (w) shall remain in full force and effect, (ii) with respect to any pending sale, through the Manager for the Company, the obligations of the Company, including in respect of compensation of the Manager, shall remain in full force and effect notwithstanding the termination and (iii) the provisions of Section 4(i), Section 6 and Section 7 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) The Manager shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Shares in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that the provisions of Section 4(i), Section 6 and Section 7 of this Agreement shall remain in full force and effect notwithstanding such termination.

(c) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 8(a) or (b) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that Section 4(i), Section 6 and Section 7 shall remain in full force and effect.

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Manager or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of the Shares, such sale shall settle in accordance with the provisions of Section 3(a)(vi) of this Agreement.

(e) In the case of any purchase by the Manager pursuant to a Terms Agreement, the obligations of the Manager pursuant to such Terms Agreement shall be subject to termination in the absolute discretion of the Manager, if, since the time of execution of the Terms Agreement or the respective dates as of which information is given in the Registration Statement, the Basic Prospectuses, the Prospectus and the Permitted Free Writing Prospectuses, if any, there shall have occurred any downgrading, or any notice or announcement shall have been given or made of (i) any intended or potential downgrading or (ii) any review or possible change that does not indicate an improvement, in the rating accorded any securities of or guaranteed by the Company or any Subsidiary by any “nationally recognized statistical rating organization”, as that term is defined in Rule 436(g)(2) under the Act or, if, at any time prior to the Time of Delivery, trading in securities on the Nasdaq shall have been suspended or limitations or minimum prices shall have been established, trading in the securities of the Company on the Nasdaq shall have been suspended, or if a banking moratorium shall have been declared either by the United States or New York State authorities, or if the United States shall have declared war in accordance with its constitutional processes or there shall have occurred any material outbreak or escalation of hostilities or other national or international calamity or crisis of such magnitude in its effect on the financial markets of the United States as, in the Manager’s judgment, to make it impracticable to market the Shares. If the Manager elects to terminate its obligations pursuant to this Section 8(e), the Company shall be notified promptly in writing.

No other person, partnership, association or corporation (including a purchaser, as such purchaser, from the Manager) shall acquire or have any right under or by virtue of this Agreement and any Terms Agreement.

SECTION 11. No Fiduciary Relationship. The Company hereby acknowledges that the Manager is acting solely as sales agent and/or principal in connection with the purchase and sale of the Company’s securities. The Company further acknowledges that the Manager is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis, and in no event do the parties intend that the Manager act or be responsible as a fiduciary to the Company, its management, stockholders or creditors or any other person in connection with any activity that the Manager may undertake or have undertaken in furtherance of the purchase and sale of the Company’s securities, either before or after the date hereof. The Manager hereby expressly disclaims any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Manager agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Manager to the Company regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Company’s securities, do not constitute advice or recommendations to the Company. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Manager with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

SECTION 12. Adjustments for Stock Splits. The parties acknowledge and agree that all share related numbers contained in this Agreement and any Terms Agreement shall be adjusted to take into account any stock split effected with respect to the Shares.

SECTION 13. Entire Agreement. This Agreement and any Terms Agreement constitute the entire agreement and supersedes all other prior and contemporaneous agreements and undertakings, both written and oral, among the parties hereto with regard to the subject matter hereof.

SECTION 14. Counterparts. This Agreement and any Terms Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

SECTION 15. Law; Construction. This Agreement, any Terms Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement or any Terms Agreement (“Claim”), directly or indirectly, shall be governed by, and construed in accordance with, the internal laws of the State of New York.

SECTION 16. Headings. The Section headings in this Agreement and any Terms Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement or any Terms Agreement.

SECTION 17. Submission to Jurisdiction. Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Company consents to the jurisdiction of such courts and personal service with respect thereto. The Company hereby consents to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement and any Terms Agreement is brought by any third party against the Manager or any indemnified party. Each of the Manager and the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement and any Terms Agreement. The Company agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Company and may be enforced in any other courts to the jurisdiction of which the Company is or may be subject, by suit upon such judgment.

SECTION 18. Successors and Assigns. This Agreement shall be binding upon the Manager and the Company and their successors and assigns and any successor or assign of any substantial portion of the Company’s and the Manager’s respective businesses and/or assets.

SECTION 19. Miscellaneous. The Manager, an indirect, wholly-owned subsidiary of UBS AG, is not a bank and is separate from any affiliated bank, including any U.S. branch or agency of UBS AG. Because the Manager is a separately incorporated entity, it is solely responsible for its own contractual obligations and commitments, including obligations with respect to sales and purchases of securities. Securities sold, offered or recommended by the Manager are not deposits, are not insured by the Federal Deposit Insurance Corporation, are not guaranteed by a branch or agency, and are not otherwise an obligation or responsibility of a branch or agency.

A lending affiliate of the Manager may have lending relationships with issuers of securities underwritten or privately placed by the Manager. To the extent required under the securities laws, prospectuses and other disclosure documents for securities underwritten or privately placed by the Manager will disclose the existence of any such lending relationships and whether the proceeds of the issue will be used to repay debts owed to affiliates of the Manager.

If the foregoing correctly sets forth the understanding between the Company and the Manager, please so indicate in the space provided below for that purpose, whereupon this Agreement and your acceptance shall constitute a binding agreement between the Company and the Manager. Alternatively, the execution of this Agreement by the Company and its acceptance by or on behalf of the Manager may be evidenced by an exchange of telegraphic or other written communications.

Very truly yours,

UBS Securities LLC

Xxx Xxxx, XX 00000-0000

Re:

Hoku Scientific, Inc.

Ladies and Gentlemen:

We have acted as legal counsel to Hoku Scientific, Inc., a Delaware corporation (the “Company”), in connection with the transactions contemplated by the Equity Distribution Agreement, dated June 12, 2008 (the “Equity Distribution Agreement”), between the Company and UBS Securities LLC (the “Manager”), including the issuance and sale through or to the Manager, as sales agent and/or principal, of shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), having an aggregate offering price of up to $54,000,000 (the “Shares”). We are rendering this legal opinion pursuant to Section 5(c) of the Equity Distribution Agreement. Unless otherwise indicated, capitalized terms not otherwise defined herein shall have the meanings set forth in the Equity Distribution Agreement.

In connection with this opinion, we have examined and relied upon the representations and warranties as to factual matters contained in and made pursuant to the Equity Distribution Agreement by the various parties. We have examined originals, or copies certified to our satisfaction, of such records, documents, certificates, opinions, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinions expressed below.

As to certain factual matters, we have relied upon certificates of officers of the Company and have not sought to verify independently such factual matters. Where we render an opinion “to our knowledge” or concerning an item “known to us,” our investigation of the factual basis for such opinion consists solely of (i) an inquiry of all attorneys within this firm who have represented the Company, (ii) receipt of a certificate executed by officers of the Company covering such matters, a copy of which is attached as Annex A hereto (the “Officers’ Certificate”), and (iii) such other investigation, if any, that we specifically set forth herein, and such references are intended to mean the current knowledge of such attorneys within this firm. We have conducted no further investigation with respect to those factual matters which are qualified in this letter “to our knowledge” or as “known to us”.

In rendering this opinion, we have assumed: the genuineness and authenticity of all signatures on original documents; the authenticity of all documents submitted to us as originals; the conformity to originals of all documents submitted to us as copies; the accuracy, completeness and authenticity of certificates of public officials; and the due authorization, execution and delivery of all documents (except the due authorization, execution and delivery by the Company of the Equity Distribution Agreement), where authorization, execution and delivery are prerequisites to the effectiveness of such documents. We have also assumed: that all individuals executing and delivering documents in their individual capacities had the legal capacity to so execute and deliver; that the Equity Distribution Agreement is an obligation binding upon you; and that there are no extrinsic agreements or understandings among the parties to the Equity Distribution Agreement or to any of the Agreements and Instruments (as defined below) that would modify or interpret the terms thereof or the respective rights or obligations of the parties thereunder.

We are qualified to practice law in the State of Idaho and we do not express any opinions in this letter concerning any law other than the laws of the State of Idaho, the General Corporation Law of the State of Delaware and the federal laws of the United States of America, except that we opine as to New York law with respect to the opinions set forth in paragraphs 12 and 13 (to the extent the agreements referenced in those paragraphs are governed by New York law). In connection with our opinion in paragraph 2 solely with respect to whether the Subsidiaries have been duly formed, we have assumed that the limited liability company act of the State of Hawaii is similar to the limited liability company act of the State of Idaho.

We are not rendering any opinion or assurance as to compliance with state securities or blue sky laws in connection with the offer and sale of the Shares or clearance with the Financial Industry Regulatory Authority (“FINRA”) with respect to the Manager.

With regard to our opinions in paragraphs 1, 2 and 3 below (i) solely with respect to the good standing of the Company and the Subsidiaries, we have relied solely upon the certificates of the Secretaries of State of the indicated jurisdictions as of a recent date; and (ii) solely with respect to the qualification of the Company and the Subsidiaries to do business as a foreign corporation or limited liability company, as applicable, we have based our opinion solely upon an examination of certificates of good standing issued by the office of the Secretaries of State of the indicated jurisdictions as of a recent date.

With respect to our opinions in paragraph 6 and 7 below solely with respect to full payment of the outstanding capital stock of the Company, we have examined and relied upon the Officers’ Certificate to the effect that the consideration for all outstanding shares of capital stock of the Company was received by the Company in accordance with the provisions of the applicable resolutions of the Board of Directors and any plan or agreement relating to the issuance of such shares.

With regard to our opinion in paragraph 11 below, our opinion is based solely upon oral advice from the staff of the Securities and Exchange Commission (the “Commission”) that the Registration Statement was declared effective under the Securities Act of 1933, as amended, and that no stop order suspending the effectiveness of the Registration Statement has been issued and that no proceedings for that purpose have been initiated or are pending or contemplated by the Commission.

With regard to our opinion in paragraph 13 below, (i) with respect to the Agreements and Instruments, our investigation of the factual basis for such opinion consists solely of (A) the Officers’ Certificate and (B) an examination of copies of the Agreements and Instruments which have been filed as exhibits to the Incorporated Documents, and (ii) solely with respect to decrees, judgments or orders, our investigation of the factual basis for such opinion consists solely of (A) the Officers’ Certificate and (B) an inquiry of all attorneys within this firm who have represented the Company.

With regard to our opinion in paragraph 15 below with respect to legal or governmental proceedings, we have relied upon (i) the Officers’ Certificate, (ii) an inquiry of all attorneys within this firm who have represented the Company, and (iii) a review of the records of this firm to ascertain whether we are acting as counsel of record for the Company in any such matter.

With regard to our opinion in paragraph 16 below, we have relied upon a certificate of the Chief Financial Officer of the Company, in the form attached as Annex B hereto, regarding (i) the value of the Company’s investment securities immediately prior to the receipt of any proceeds from the sale and issuance of the Shares, (ii) the immediate application by the Company of all proceeds received from the sale and issuance of the Shares, and (iii) any intention by the Company to dispose of assets as of the date hereof. The terms “value” and “investment securities” have the meanings ascribed to them in Section 2(a)(41) and Section 3(a)(2), respectively, of the Investment Company Act of 1940, as amended.

On the basis of the foregoing, in reliance thereon and with the foregoing qualifications, we are of the opinion that:

The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware, with full corporate power and authority to own, lease and operate its properties and conduct its business as described in the Registration Statement (including the Basic Prospectus attached thereto, dated June 2, 2008, and the documents incorporated by reference therein) and the Prospectus, to execute and deliver the Equity Distribution Agreement and any applicable Terms Agreement and to perform its obligations thereunder, including, without limitation, to issue, sell and deliver the Shares as contemplated by the Equity Distribution Agreement.

Each of the Subsidiaries has been duly incorporated or formed and is validly existing as a corporation or limited liability company, as applicable, in good standing under the laws of its jurisdiction of incorporation or formation, with full corporate power or limited liability company power, as applicable, and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the Basic Prospectus and the Prospectus.

The Company and the Subsidiaries are each duly qualified to do business as a foreign corporation or limited liability company, as applicable, and are in good standing in each jurisdiction where the ownership or leasing of their respective properties or the conduct of their respective businesses requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, have a Material Adverse Effect.

4.	The Equity Distribution Agreement and any applicable Terms Agreement have been duly authorized, executed and delivered by the Company.

5.	The Shares when paid for in accordance with the terms of the Equity Distribution Agreement and any applicable Terms Agreement will be duly authorized and validly issued and are fully paid and non-assessable.

The Company has an authorized and outstanding capitalization as set forth in the Registration Statement, the Basic Prospectus and the Prospectus as of the dates stated therein; all of the issued and outstanding shares of capital stock of the Company have been duly authorized and validly issued, are fully paid and non-assessable and are free of statutory preemptive rights and, to our knowledge, contractual preemptive rights, resale rights, rights of first refusal and similar rights; the Shares are free of statutory preemptive rights and, to our knowledge, contractual preemptive rights, resale rights, rights of first refusal and similar rights; the certificates for the Shares are in due and proper form.

All of the outstanding shares of capital stock of each of the Subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and, except as otherwise disclosed in the Registration Statement (excluding the exhibits thereto), the Basic Prospectus and the Prospectus, are owned by the Company, in each case subject to no security interest, other encumbrance or adverse claim; the Shares are duly listed, and admitted and authorized for trading, on the NASDAQ Global Market (“Nasdaq”).

8.	The capital stock of the Company, including the Shares, conforms in all material respects to the description thereof, if any, contained in the Registration Statement, the Basic Prospectus and the Prospectus.

The Registration Statement, the Basic Prospectus and the Prospectus (except as to the financial statements and schedules, and other financial data derived therefrom, contained in the Registration Statement, the Basic Prospectus and the Prospectus, as to which we express no opinion) comply as to form in all material respects with the requirements of the Act (including, in the case of the Prospectus, Section 10(a) of the Act); the conditions to the use of Form S-3 in connection with the offering and sale of the Shares as contemplated by the Equity Distribution Agreement have been satisfied; the Registration Statement meets, and the offering and sale of the Shares as contemplated by the Equity Distribution Agreement complies with, the requirements of Rule 415 under the Act; and each Incorporated Document, at the time such document was filed with the Commission or at the time such document became effective, as applicable, complied as to form in all material respects with the requirements of the Exchange Act (except as to the financial statements and schedules, and other financial data derived therefrom, contained in such document, as to which we express no opinion).

10.	To our knowledge, the Company is not an “ineligible issuer” (as defined in Rule 405 under the Act) as of the eligibility determination date for purposes of Rules 164 and 433 under the Act with respect to the offering of the Shares contemplated by the Registration Statement.

11.

The Registration Statement has become effective under the Act and, to our knowledge, no stop order proceedings with respect thereto are pending or threatened under the Act, and any required filing of the Prospectus and any supplement thereto pursuant to Rule 424 or Rule 430B under the Act has been made in the manner and within the time period required by such Rule 424 and in compliance with Rule 430B under the Act.

12.

No approval, authorization, consent or order under any federal law, the laws of the State of New York or under the Delaware General Corporation Law or approval, authorization, consent of or filing with any New York or Delaware governmental or regulatory commission, board, body, authority or agency, or approval of the stockholders of the Company, is required in connection with the issuance and sale of the Shares by the Company of the transactions contemplated by the Equity Distribution Agreement and any applicable Terms Agreement other than registration of the Shares under the Act (except that we express no opinion as to any necessary qualification under the state securities or blue sky laws of the various jurisdictions in which the Shares are being offered by the Manager and we express no opinion with respect to the Conduct Rules of FINRA as applicable to the Manager).

13.

The execution, delivery and performance of the Equity Distribution Agreement and any applicable Terms Agreement by the Company, the issuance and sale of the Shares and the consummation of the transactions contemplated by the Equity Distribution Agreement and any applicable Terms Agreement do not and will not result in any breach or violation of or constitute a default under (nor constitute any event which, with notice, lapse of time or both, would result in any breach or violation of or constitute a default under or give the holder of any indebtedness (or a person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a part of such indebtedness under) (or result in the creation or imposition of a lien, charge or encumbrance on any property or assets of the Company or any Subsidiary pursuant to) (i) the charter or bylaws or operating agreements of the Company or any of the Subsidiaries, as applicable, or (ii) any indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any license, lease, contract or other agreement or instrument (collectively, “Agreements and Instruments”) which is filed as an exhibit to the Registration Statement or any Incorporated Document, or (iii) federal laws, the laws of the State of New York or the Delaware General Corporation Law, or (iv) any decree, judgment or order applicable to the Company or any of the Subsidiaries or any of their respective properties, which decree, judgment or order is known to us, or (v) the rules and regulations of Nasdaq.

14.

To our knowledge, there are no contracts, licenses, agreements, leases or documents of a character which are required to be described in the Registration Statement, the Basic Prospectus or the Prospectus or to be filed as an exhibit to the Registration Statement or any Incorporated Document which have not been so described or filed as required.

15.

To our knowledge, (i) the Company is not a party to any legal or governmental action or proceeding that challenges the validity or enforceability, or seeks to enjoin the performance, of the Equity Distribution Agreement and any applicable Terms Agreement; and (ii) there are no actions, suits, claims, investigations or proceedings pending, threatened or contemplated to which the Company or any of the Subsidiaries or any of their respective directors or officers is or would be a party or to which any of their respective properties is or would be subject at law or in equity, before or by any federal, state, local or foreign governmental or regulatory commission, board, body, authority or agency which are required to be described in the Registration Statement, the Basic Prospectus or the Prospectus but are not so described as required.

16.	Neither the Company nor any Subsidiary is and, after giving effect to the offering and sale of the Shares, neither will be an “investment company” “or an entity “controlled” by an “investment company,” as such terms are defined in the Investment Company Act

17.

The statements in the Registration Statement, the Basic Prospectus and the Prospectus under the heading “Description of Capital Stock,” insofar as such statements constitute summaries of documents or legal proceedings or refer to matters of law or legal conclusions, present fairly, to the extent required by the Act and the rules thereunder, in all material respects, such legal matters and proceedings or documents.

18.

No person has the right, pursuant to the terms of any contract, agreement or other instrument described in or filed as an exhibit to the Registration Statement or any Incorporated Document or otherwise known to us, to cause the Company to register under the Act any shares of Common Stock or shares of any other capital stock or other equity interest in the Company or to include any such shares or interest in the Registration Statement or the offering contemplated thereby.

19.

To our knowledge, the contracts listed on Annex C hereto are valid, binding and enforceable obligations of the parties thereto (except that such enforceability (A) may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting or relating to the enforcement of creditors’ rights generally and (B) is subject to general principles of equity (regardless of whether considered in a proceeding in equity or at law)) and are in full force and effect.

In addition, we have participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company and representatives of the Manager at which the contents of the Registration Statement, the Basic Prospectus and the Prospectus were discussed and, although we are not passing upon and do not assume responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Basic Prospectus or the Prospectus (except as and to the extent stated in subparagraphs 6, 8 and 17 above), on the basis of the foregoing, no facts have come to our attention that cause us to believe that (i) the Registration Statement, at the Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Prospectus, as of the date of the Prospectus Supplement, or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) the Basic Prospectus, as of its date, the date of the Equity Distribution Agreement or the date hereof, in each case together with the information relating to the public offering price of the Shares as set forth on the cover page of the Prospectus, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that we express no opinion in this paragraph with respect to the financial statements and schedules, and other financial data derived therefrom, included in the Registration Statement, the Basic Prospectus or the Prospectus).
