Effect; all of the Intangibles are valid and in full force and effect, except when the invalidity of such Intangibles or the failure of such Intangibles to be in full force and effect is not reasonably likely to, individually or in the aggregate, result in a Material Adverse Effect; the Company and its Subsidiaries have not received any notice of proceedings relating to the revocation or modification of any such Intangibles which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would be reasonably likely to result in a Material Adverse Effect; the Company and its Subsidiaries have not violated or received written notice of any infringement of or conflict with (and the Company does not know of any such infringement of or conflict with) asserted rights of others with respect to any such Intangibles, except where the infringement of or conflict with is not reasonably likely to, individually or in the aggregate, result in a Material Adverse Effect.

(xxi) Personal Property. Neither the Company nor any Subsidiary owns any real property or holds any real property lease. The Company and its Subsidiaries have good title to all personal property, if any, owned by them, in each case, free and clear of all liens, security interests, pledges, charges, encumbrances, mortgages and defects, except as are disclosed in the Registration Statement, the General Disclosure Package and the Prospectus or as could not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

(xxii) Investment Company Act. The Company is not required to register as an “investment company” under the Investment Company Act of 1940, as amended (the “1940 Act”).

(xxiii) Registration Rights. Except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus or which have been waived, there are no persons with registration or other similar rights to have any equity or debt securities, including securities that are convertible into or exchangeable for equity securities, registered pursuant to the Registration Statement or otherwise registered by the Company under the 1933 Act; no person has a right of participation, first refusal or similar right with respect to the sale of the Securities by the Company.

(xxiv) Accounting Controls and Disclosure Controls. The Company and each of its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurances that (A) transactions are executed in accordance with management’s general or specific authorization; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (C) receipts and expenditures are being made only in accordance with management’s general or specific authorization; (D) access to assets is permitted only in accordance with management’s general or specific authorization; and (E) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as described in the Registration Statement, the General Disclosure Package and the Prospectus, since the end of the Company’s most recent audited fiscal year, there has been (A) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (B) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company and its

Subsidiaries, considered as one enterprise, have established and currently maintain disclosure controls and procedures that comply with Rule 13a-15 under the 1934 Act and the Company has determined that such disclosure controls and procedures are effective in compliance with Rule 13a-15 under the Exchange Act.

(xxv) No Commissions. Neither the Company nor any of its Subsidiaries is a party to any contract, agreement or understanding with any person (other than as contemplated by this Agreement) that would give rise to a valid claim against the Company or any of its Subsidiaries or the Underwriter for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Securities by the Underwriter under this Agreement.

(xxvi) Actively-Traded Security. The Common Stock is an “actively-traded security” exempted from the requirements of Rule 101 of Regulation M under the 1934 Act by subsection (c)(1) of such rule.

All tax returns of the Company and its Subsidiaries required by law to be filed have been filed and all taxes shown by such returns or otherwise assessed, which are due and payable, have been paid, except assessments against which appeals have been or will be promptly taken and as to which adequate reserves have been provided. The charges, accruals and reserves on the books of the Company in respect of any income and corporation tax liability for any years not finally determined are adequate to meet any assessments or re-assessments for additional income tax for any years not finally determined, except to the extent of any inadequacy that would not result in a Material Adverse Effect.

(xxix) Absence of Transfer Taxes. There are no transfer taxes or other similar fees or charges under federal law or the laws of any state, or any political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the sale by the Company of the Securities under this Agreement.

The Company has no reason to believe that it or any Subsidiary will not be able (A) to renew its existing insurance coverage as and when such policies expire or (B) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not result in a Material Adverse Effect. Neither the Company nor any Subsidiary has been denied any material insurance coverage which it has sought or for which it has applied.

(xxxviii) REIT Status. Commencing with its initial taxable year ended December 31, 2008, the Company has been organized and operated in conformity with the requirements for qualification and taxation as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (collectively, the “Code”), and the Company’s current and proposed method of operations as described in the Registration Statement, the General Disclosure Package and the Prospectus will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Code for its taxable year ending December 31, 2010 and thereafter. No transaction or other event has occurred that could cause the Company to not be able to qualify as a REIT for its taxable year ending December 31, 2010 or future taxable years. Except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, the Company and each of its Subsidiaries have no intention of changing their operations or engaging in activities that would cause the Company to fail to qualify, or make economically undesirable the Company’s continued qualification, as a REIT under the Code.

(xl) Description of Organization and Method of Operations. The description of the Company’s organization and current and proposed method of operations and its qualification and taxation as a REIT set forth in the Registration Statement, the General Disclosure Package and the Prospectus is accurate in all material respects and presents fairly the matters referred to therein. The Company’s conflicts of interest, operating policies, investment guidelines and operating restrictions described or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus accurately reflect in all material respects the guidelines and policies of the Company with respect to the operation of its business, and no material deviation from such guidelines or policies is currently contemplated.

(xli) Director Independence. Each of the independent directors (or independent director nominees, once appointed, if applicable) named in the Registration

Statement, the General Disclosure Package and Prospectus satisfies the independence standards established by Nasdaq and, with respect to members of the Company’s audit committee, the enhanced independence standards contained in Rule 10A-3(b)(1) promulgated by the Commission under the 1934 Act.

The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated herein and in the Registration Statement, the General Disclosure Package and the Prospectus and compliance by the Manager with its obligations under this Agreement do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Manager pursuant to the Manager Agreements and Instruments, nor will such action result in any violation of the provisions of the limited liability company operating agreement or other organizational documents of the Manager or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Manager or any of its assets, properties or operations, except as would not result in a Manager Material Adverse Effect.

(iv) Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Manager, threatened, against or affecting the Manager, except for such matters that could not, individually or in the aggregate, result in a Manager Material Adverse Effect.

The Manager possesses such Intangibles issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus, except where the failure so to possess would not, individually or in the aggregate, result in a Manager Material Adverse Effect; the Manager is in compliance with the terms and conditions of all such Intangibles, except where the failure so to comply would not, individually or in the aggregate, result in a Manager Material Adverse Effect; all of the Intangibles are valid and in full force

and effect, except when the invalidity of such Intangibles or the failure of such Intangibles to be in full force and effect would not have a Manager Material Adverse Effect; and the Manager has not received any notice of proceedings relating to the revocation or modification of any such Intangibles which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Manager Material Adverse Effect.

(viii) Employment; Noncompetition; Nondisclosure.

(a) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b) hereof, will comply with the requirements of Rule 430B and will notify the Representatives promptly, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall have been declared effective, or any supplement to the Prospectus or any amended Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, or of any order preventing or suspending the use of any Preliminary Prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Securities. The Company will effect the filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)). The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments and Exchange Act Documents. The Company will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)) or any amendment, supplement or revision to any Preliminary Prospectus or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, and the Company will furnish the Representatives 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 Representatives or counsel for the Underwriters shall reasonably object, except as required by law. The Company has given the

Representatives notice of any filings made pursuant to the 1934 Act or 1934 Act Regulations within 48 hours prior to the execution of this Agreement; the Company will give the Representatives notice of its intention to make any such filing from the execution of this Agreement to the Closing Time and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing and will not file or use any such document to which the Representatives or counsel for the Representatives shall reasonably object, except as required by law.

(c) Delivery of Registration Statements. The Company has furnished or will deliver to the Representatives and counsel for the Underwriters, without charge, conformed copies of the Registration Statement and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein or otherwise deemed to be a part thereof) and conformed copies of all consents and certificates of experts, and will also deliver to the Representatives, without charge, a conformed copy of the Registration Statement 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 the Electronic Data Gathering, Analysis and Retrieval system (“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 each Preliminary 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 and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Securities 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 Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the 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 or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to comply with such requirements, the Company will use its best efforts to have such amendment declared effective as soon as practicable (if it is not an automatic shelf registration statement with respect to the Securities) and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs

an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, the General Disclosure Package or the Prospectus, or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(f) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications in effect for a period of not less than one year from the date hereof; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

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

The foregoing sentence shall not apply to the (A) Securities to be sold hereunder, (B) any shares of Common Stock sold pursuant to the Company’s Direct Stock Purchase Program and Dividend Reinvestment Program; provided that the Company shall not grant any purchase volume waivers under such plan during the period of 30 days from the date of the Prospectus, (C) any shares of Common Stock issued or options to purchase Common Stock granted pursuant to existing employee benefit plans of the Company or (D) any shares of Common Stock issued pursuant to any non-employee director stock plans or dividend reinvestment plans.

(k) Issuer Free Writing Prospectuses. Each of the Company and the Manager represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company, the Manager and the Representatives, it has not made and will not make any offer relating to the Securities that would constitute an “issuer free writing prospectus,” as defined in Rule 433, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company, the Manager and the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” Each of the Company and the Manager represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

(l) Share Price Manipulation. Each of the Company and the Manager agrees that it will not, and will cause its respective officers and directors (and in the case of the Manager, ACAS) and their respective subsidiaries not to, take, directly or indirectly, any action designed to, or that might be reasonably expected to, cause or result in stabilization or manipulation of the price of the Securities to facilitate the sale or resale of the Securities, provided that the Company may bid for and purchase its Common Stock in accordance with Rule 10b-18 under the 1934 Act.

(m) REIT Qualification. The Company will use its best efforts to continue to meet the requirements for qualification and taxation as a REIT under the Code, subject to any future determination by the Company’s board of directors that it is no longer in the Company’s best interests to qualify as a REIT.

(n) Investment Company Act. The Company will use its best efforts to conduct its affairs and the affairs of its Subsidiaries in such a manner so as to ensure that neither the Company nor any of its Subsidiaries will be an “investment company” (as defined in the Investment Company Act of 1940 (the “1940 Act”)) or an entity “controlled” by an investment company that is required to be registered under the 1940 Act.

(o) Undertakings. The Company will comply with all of the provisions of any undertakings in the Registration Statement.

(p) Transfer Agent. The Company has engaged and will maintain, at its sole expense, a registrar and transfer agent for the Securities.

Section 6. Indemnification.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its Affiliates, its selling agents and each person, if any, who controls the Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any 462(b) Registration Statement, and including the Rule 430B Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any Preliminary Prospectus and the General 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, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in any Issuer Limited Use Free Writing Prospectus 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;

(iii) 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;

(iv) against any and all expense (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 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 the Underwriter Content.

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense 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, the General Disclosure Package or the Prospectus in reliance upon and in conformity with the Underwriter Content. The Company hereby acknowledges that the only information that the Underwriters have furnished to the Company expressly for use in the Registration Statement, the General Disclosure Package or the Prospectus are the statements set forth under the caption “Underwriting” in such documents as follows: the first and second sentences of paragraph 9, and the third and fourth sentences of paragraph 10, each relating to price stabilization activities and paragraph 11 relating to electronic prospectus delivery (collectively, the “Underwriter Content”).

(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 case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 6 for any legal or other expenses subsequently incurred by such indemnified party in connection

with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party, representing the indemnified parties who are parties to such action), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, or (iii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlement without Consent if Failure to Reimburse. The indemnifying party under this Section 6 shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 6(d) hereof, the indemnifying party 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 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes (i) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding 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.

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 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 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 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 and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus bear to the aggregate public offering price of the Securities as set forth on the cover of the Prospectus.

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.

Notwithstanding the provisions of this Section 7, (i) no Underwriter shall be required to contribute an amount in excess of the underwriting discounts and commissions applicable to the Securities purchased by such Underwriter and (ii) 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 and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.

The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule I hereto and not joint.

Section 8. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or the Manager submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors or any person controlling the Company, the person controlling the Manager and (ii) delivery of and payment for the Securities.

Section 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Prospectus (exclusive of any supplement thereto), any Material Adverse Effect or Manager Material Adverse Effect, 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 (ii) 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 material and adverse 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 Underwriter, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or Nasdaq, or if trading generally on the New York Stock Exchange or The NASDAQ Stock Market, Inc. 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 order of the Commission, FINRA or any other governmental authority, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States such that settlement and clearance of the sale of the Securities is impracticable or impossible, or (v) if a banking moratorium has been declared by either federal or New York State authorities.

(b) Liabilities and Expenses. If this Agreement is terminated pursuant to this Section 9, (i) such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that this paragraph and Sections 1, 6, 7 and 9(a) shall survive such termination and remain in full force and effect, and (ii) the Underwriters shall only be entitled to receive out-of-pocket expenses actually incurred.

Section 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time or a Date of Delivery 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:

(i) 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 their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii) 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 Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Company to sell the Option Securities to be purchased and sold on such Date of Delivery, shall terminate without liability on the part of any non-defaulting Underwriter.

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

In the event of any such default which does not result in a termination of this Agreement or, in the case of a 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 Securities, as the case may be, either (i) the Representatives or (ii) the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

Section 11. Tax Disclosure. Notwithstanding any other provision of this Agreement, from the commencement of discussions with respect to the transactions contemplated hereby, the Company (and each employee, representative or other agent of the Company) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure (as such terms are used in Sections 6011, 6111 and 6112 of the U.S. Code and the Treasury Regulations promulgated thereunder) of the transactions contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to the Company relating to such tax treatment and tax structure.

Goldschmidt, Esq.

Section 13. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Manager, on the one hand, and the several Underwriters, on the other hand, (ii) in connection with the offering contemplated hereby and the process leading to such transaction the Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, the Manager, or their respective stockholders, creditors, employees or any other party, (iii) the Underwriter has not assumed and will not assume an advisory or fiduciary responsibility in favor of the Company or the Manager with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether the Underwriter has advised or is currently advising the Company or the Manager on other matters) and the Underwriter has no obligation to the

Company or the Manager with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (iv) the Underwriters and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of each of the Company and the Manager, and (v) the Underwriters and their respective agents have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company and the Manager have consulted their own respective legal, accounting, regulatory and tax advisors to the extent each deemed appropriate.

Section 14. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Manager and the Underwriters, or any of them, with respect to the subject matter hereof.

Section 15. Parties. This Agreement shall each inure to the benefit of and be binding upon the Underwriters, the Company, the Manager and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company, the Manager and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company, the Manager and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

Section 16. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

Re:

Certain United States Federal Income Tax Matters

Ladies and Gentlemen:

You have requested our opinion concerning certain United States Federal income tax considerations in connection with the sale (the “Sale”) by American Capital Agency Corp., a Delaware corporation (“ACAC”), to the several Underwriters named in Schedule I ( the “Underwriters”) of the Underwriting Agreement among Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Deutsche Bank Securities Inc. and UBS Securities LLC as representatives of the several Underwriters, and ACAC and American Capital Agency Management, LLC, dated as of September [27], 2010 (the “Underwriting Agreement”), of [11,500,000] shares of ACAC’s common stock, par value $0.01 per share, and an additional [1,725,000] shares of ACAC’s common stock at the Underwriters’ option to cover over-allotments (collectively, the “Shares”), pursuant to a shelf registration statement on Form S-3 filed with the Securities and Exchange Commission (the “Commission”), which was declared effective by the Commission on July 13, 2009, including the base prospectus dated as of July 13, 2009, the preliminary prospectus supplement thereto dated as of September [27], 2010, and the

B-1

final prospectus supplement thereto dated as of September [27], 2010 (the “Offering Documents”). We have acted as tax counsel to ACAC in connection with, and have participated in the preparation of, the Offering Documents. This opinion is being furnished to you pursuant to Section 5(b) of the Underwriting Agreement. Capitalized terms used herein but not defined shall have the meanings set forth in the Underwriting Agreement.

In connection with this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of the Offering Documents and such other documentation and information provided to us by ACAC as we have deemed necessary or appropriate as a basis for the opinion set forth herein. In addition, ACAC has provided us with, and we are relying upon, a certificate containing certain factual statements, factual representations and covenants of officers of ACAC (the “Officers’ Certificate”) relating to, among other things, the actual and proposed operations of ACAC and the entities in which it holds, or has held, a direct or indirect interest (collectively, the “Company”). For purposes of our opinion, we have not independently verified the facts, statements, representations and covenants set forth in the Officers’ Certificate, the Offering Documents, or in any other document. In particular, we note that the Company may engage in transactions in connection with which we have not provided legal advice, and have not reviewed, and of which we may be unaware. Consequently, we have relied on ACAC’s representation that the facts, statements, representations, and covenants presented in the Officers’ Certificate, the Offering Documents, and other documents, or otherwise furnished to us, accurately and completely describe all material facts relevant to our opinion. We have assumed that all such facts, statements, representations and covenants are true without regard to any qualification as to knowledge, belief, intent, materiality, or otherwise. Our opinion is conditioned on the continuing accuracy and completeness of such facts, statements, representations and covenants. We are not aware of any facts inconsistent with the statements in the Officers’ Certificate. Any material change or inaccuracy in the facts, statements, representations, and covenants referred to, set forth, or assumed herein or in the Officers’ Certificate may affect our conclusions set forth herein.

In our review of certain documents in connection with our opinion as expressed below, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed, photostatic, or electronic copies, and the authenticity of the originals of such copies. Where documents have been provided to us in draft form, we have assumed that the final executed versions of such documents will not differ materially from such drafts.

Our opinion is also based on the correctness of the following assumptions: (i) ACAC and each of the entities comprising the Company has been and will continue to be operated in accordance with the laws of the jurisdictions in which they were formed, and in the manner described in the relevant organizational documents, (ii) there will be no changes in the applicable laws of the State of Delaware or of any other jurisdiction under the laws of which any of the entities comprising the Company have been formed, and (iii) each of the written agreements to which the Company is a party has been and will be implemented, construed and enforced in accordance with its terms.

B-2

In rendering our opinion, we have considered and relied upon the Internal Revenue Code of 1986, as amended (the “Code”), the regulations promulgated thereunder (“Regulations”), administrative rulings and other Treasury interpretations of the Code and the Regulations by the courts and the Internal Revenue Service (“IRS”), all as they exist at the date hereof. It should be noted that the Code, Regulations, judicial decisions, and administrative interpretations are subject to change at any time and, in some circumstances, with retroactive effect. A material change that is made after the date hereof in any of the foregoing bases for our opinion could affect our conclusions set forth herein. In this regard, an opinion of counsel with respect to an issue represents counsel’s best judgment as to the outcome on the merits with respect to such issue, is not binding on the IRS or the courts, and is not a guarantee that the IRS will not assert a contrary position with respect to such issue or that a court will not sustain such a position if asserted by the IRS.

We express no opinion as to the laws of any jurisdiction other than the federal laws of the United States. We express no opinion on any issue relating to ACAC or any investment therein, other than as expressly stated herein.

TO ENSURE COMPLIANCE WITH TREASURY DEPARTMENT CIRCULAR 230, YOU ARE HEREBY NOTIFIED THAT: (A) ANY FEDERAL TAX ADVICE CONTAINED HEREIN IS NOT INTENDED OR WRITTEN TO BE USED, AND CANNOT BE USED BY ANY PERSON, FOR THE PURPOSE OF AVOIDING PENALTIES THAT MAY BE IMPOSED UNDER THE CODE; (B) THE ADVICE IS WRITTEN IN CONNECTION WITH THE PROMOTION OR MARKETING OF THE TRANSACTION OR THE MATTERS ADDRESSED HEREIN BY THE COMPANY; AND (C) YOU SHOULD SEEK ADVICE BASED ON YOUR PARTICULAR CIRCUMSTANCES FROM AN INDEPENDENT TAX ADVISOR.

Based on and subject to the foregoing, we are of the opinion that:

1. Commencing with ACAC’s initial taxable year that ended on December 31, 2008, ACAC has been organized and operated in conformity with the requirements for qualification and taxation as a real estate investment trust (a “REIT”) under the Code, and its actual method of operation through the date of this opinion has enabled, and its proposed method of operation will continue to enable, it to meet the requirements for qualification and taxation as a REIT for its taxable year ending December 31, 2010 and subsequent years. As noted in the Offering Documents, ACAC’s qualification and taxation as a REIT depend upon its ability to meet, through actual operating results, certain requirements relating to the sources of its income, the nature of its assets, its distribution levels and the diversity of its stock ownership, and various other qualification tests imposed under the Code, the results of which are not reviewed by us. Accordingly, no assurance can be given that the actual results of ACAC’s operations for any one taxable year will satisfy the requirements for taxation as a REIT under the Code.

2. Although the discussion set forth in the Offering Documents under the headings “Federal Income Tax Considerations” and “Supplement to Federal Income Tax Considerations” does not purport to discuss all possible United States Federal income tax consequences of the ownership and disposition of the Shares, such discussion, though general in nature, constitutes, in all material respects, a fair and accurate summary under current law of the material United States Federal income tax consequences of the ownership and disposition of the Shares of ACAC, subject to the qualifications set forth therein.

B-3

This opinion has been prepared for you in connection with the Sale and pursuant to Section 5(b) of the Underwriting Agreement. This opinion may not be relied upon by anyone else without our prior written consent. This opinion is expressed as of the date hereof, and we are under no obligation to supplement or revise our opinion to reflect any legal developments or factual matters arising subsequent to the date hereof, or the impact of any information, document, certificate, record, statement, representation, covenant, or assumption relied upon herein that becomes incorrect or untrue.

Very truly yours,

Notwithstanding the foregoing, the undersigned may make gifts or transfers of Common Stock to, or for the benefit of, family members, charitable institutions, and trusts, limited partnerships or other entities created for estate planning purposes, the principal beneficiaries of which are family members or charitable institutions, subject to the condition that any such family member or charitable institution or other holder shall execute an agreement with the Representatives stating that such transferee is receiving and holding the shares of Common Stock subject to the provisions of this lock-up agreement. In addition, if the undersigned is a corporation, partnership, limited liability company or other entity, the undersigned may transfer shares of Common Stock to persons or other entities that own equity interests in the undersigned, subject to the condition that the recipient shall execute an agreement with the Representatives stating that such recipient is receiving and holding the shares of Common Stock subject to the provisions of this lock-up agreement.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Lock-Up Securities, except in compliance with the foregoing instructions.
