(“Citi”), Deutsche Bank Securities Inc., UBS Securities LLC, and Xxxxx Fargo Securities, LLC are acting as representatives (in such capacity, if and as applicable, the “Representatives”), with respect to (i) the sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of 8,000,000 shares of common stock, par value $0.01 per share, of the Company (“Common Stock”) and (ii) the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 1,200,000 additional shares of Common Stock to cover over-allotments, if any. The aforesaid 8,000,000 shares of Common Stock (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the 1,200,000 shares of Common Stock subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities.”

Simultaneous with the execution and delivery of this Agreement, the Company has entered

into a Stock Purchase Agreement, dated August 3, 2011 (the “Stock Purchase Agreement”), with American Capital, Ltd., a Delaware corporation (“ACAS”), relating to the issuance and sale by the Company to ACAS of an aggregate of 2,000,000 shares (the “Private Placement Shares”) of Common Stock in a private placement concurrent with the closing of the issuance and sale of the Initial Securities. At the closing of the issuance and sale of the Initial Securities: (a) the Company will enter into a registration rights agreement (the “Registration Rights Agreement”) with ACAS, pursuant to which the Company will grant certain registration rights to ACAS with respect to the Private Placement Shares; (b) the Company will enter into a management agreement (the “Management Agreement”) with the Manager, pursuant to which the Manager will manage the business and operations of the Company and its subsidiaries; and (c) the Manager will enter into an administrative services agreement (the “Administrative Services Agreement”) with ACAS and American Capital Mortgage Management, LLC, a Delaware limited liability company and sole member of the Manager (“ACM”), pursuant to which ACAS and ACM will provide the Manager with certain personnel and resources in order for the Manager to perform its obligations under the Management Agreement.

The Company and the Manager understand that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company and the Underwriters agree that up to 250,000 shares of the Initial Securities to be purchased by the Underwriters (the “Reserved Securities”) shall be reserved for sale by the Underwriters to certain officers or employees of ACM (the “Invitees”), as part of the distribution of the Securities by the Underwriters, subject to the terms of this Agreement, the applicable rules, regulations and interpretations of the Financial Industry Regulatory Authority (“FINRA”) and all other applicable laws, rules and regulations. To the extent that such Reserved Securities are not orally confirmed for purchase by Invitees by 8:00 a.m. (New York City time) on the first business day after the date of this Agreement, such Reserved Securities may be offered to the public as part of the public offering contemplated hereby.

Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430A (“Rule 430A”) of the 1933 Act Regulations (as defined below) and paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations.

The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement, the General Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein, which information is specified in Section 6(b) hereof.

The Company has made available a “bona fide electronic road show,” as defined in Rule 433, in compliance with Rule 433(d)(8)(ii) (the “Bona Fide Electronic Road Show”) such that no filing of any “road show” (as defined in Rule 433(h)) is required in connection with the offering of the Securities.

(xviii) Absence of Further Requirements.

Intangibles or the failure of such Intangibles to be in full force and effect would not be reasonably expected to result, individually or in the aggregate, 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 expected 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 any such infringement or conflict would not be reasonably expected to result, individually or in the aggregate, in a Material Adverse Effect.

(xxi) Real Property; 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 would not be reasonably expected to result, individually or in the aggregate, in a Material Adverse Effect.

(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 Company’s inception, 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.

(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 Underwriters for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Securities by the Underwriters under this Agreement.

(xxvi) Compliance with the Xxxxxxxx-Xxxxx Act.

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, 2011 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.

as the Representatives in their sole discretion shall make to eliminate any sales or purchases of fractional securities. In addition, in connection with the sale of the Initial Securities, the Manager, on its own behalf and for its own business reasons, agrees to pay Citi for the account of the Underwriters, the amount per Initial Security set forth in Schedule I for each Initial Security purchased by such Underwriter (the “Initial Securities Manager Offering Payment”).

(b) Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriters, severally and not jointly, to purchase up to an additional 1,200,000 shares of Common Stock, at the price per share set forth in paragraph (a) above. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part at any time on or before the 30th day after the date hereof only for the purpose of covering over-allotments, which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representatives to the Company setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representatives, but shall not be later than seven full business days after the exercise of said option. If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule I opposite the name of such Underwriter bears to the total number of Initial Securities, subject in each case to such adjustments as the Representatives in their sole discretion shall make to eliminate any sales or purchases of fractional shares. In addition, in connection with the sale of any Option Securities, the Manager, on its own behalf and for its own business reasons, agrees to pay Citi, for the account of the Underwriters, the amount per Option Security set forth on Schedule I for each Option Security purchased by such Underwriter (the “Option Securities Manager Offering Payment” and collectively with the Initial Securities Manager Offering Payment, the “Manager Offering Payments”).

(c) Payment. The Securities shall be delivered by the Company to the Representatives, including, at the option of the Representatives, through the facilities of DTC for the account of the Representatives, against payment by the Representatives of the purchase price therefor by wire transfer of immediately available funds to a bank account designated by the Company. The time and date of such delivery and payment for the Initial Securities and payment of the Initial Securities Manager Offering Payment shall be 10:00 a.m. (New York City time) on the third (fourth, if the pricing occurs after 4:30 p.m. (New York City time) on any given day) business day after the date hereof, or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Company (such time and date of payment and delivery being herein called “Closing Time”).

Citi, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder. Under no circumstances shall the Company bear responsibility for the payment of or liability for the Manager’s non-payment of the Manager Offering Payments.

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 Underwriters shall reasonably object, except as required by law.

(c) Delivery of Registration Statements. Upon request, the Company will furnish 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 and documents 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 XXXXX, 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 XXXXX, 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 the 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 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.

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

(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 such 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), and including the Rule 430A 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 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, 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 concession and reallowance figures in the third paragraph of text under the caption “Underwriting” and the information in the thirteenth, fourteenth and fifteenth paragraphs of text under the caption “Underwriting” (collectively, the “Underwriter Content”).

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.

(e) Indemnification for Reserved Securities. In connection with the offer and sale of the Reserved Securities, the Company agrees to indemnify and hold harmless the Underwriters, their Affiliates and selling agents and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all loss, liability, claim, damage and expense (including, without limitation, any legal or other expenses reasonably incurred in connection with defending, investigating or settling any such action or claim), as incurred, (i) arising out of the violation of any applicable laws or regulations of foreign jurisdictions where Reserved Securities have been offered; (ii) arising out of any untrue statement or alleged untrue statement of a material fact contained in any prospectus wrapper or other material prepared by or with the consent of the Company for distribution to Invitees in connection with the offering of the Reserved Securities or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (iii) caused by the failure of any Invitee to pay for and accept delivery of Reserved Securities which have been orally confirmed for purchase by any Invitee by 8:00 a.m. (New York City time) on the first business day after the date of the Agreement; or (iv) related to, or arising out of or in connection with, the offering of the Reserved Securities.

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 0000 Xxx) 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, the Manager or AGNC 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 or 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 and adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (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.

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 each 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) each 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 each 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.

Re:	Proposed Public Offering by American Capital Mortgage Investment Corp.

Dear Sirs:

The undersigned, an officer and/or director, manager or affiliate of American Capital Mortgage Investment Corp., a Maryland corporation (the “Company”), understands that Citigroup Global Markets Inc., Deutsche Bank Securities Inc., UBS Securities LLC and Xxxxx Fargo Securities, LLC (in such capacity, the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company and American Capital MTGE Management, LLC, a Delaware limited liability company and manager of the Company (the “Manager”), providing for the public offering of shares of the Company’s common stock, $0.01 par value per share (“Common Stock”). In recognition of the benefit that such an offering will confer upon the undersigned, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with the Representatives that, during a period of 180 days following the date of the Underwriting Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of the Representatives, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any of the shares of Common Stock or any securities convertible into or exchangeable or exercisable for shares of Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or file, or cause to be filed, any registration statement under the Securities Act of 1933, as amended, with respect to any of the foregoing (collectively, the “Lock-Up Securities”) or (ii) enter into any swap or any

other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of shares of Common Stock or other securities, in cash or otherwise.

Notwithstanding the foregoing, if:

(1) during the last 17 days of the Lock-Up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or

(2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of the Lock-Up Period,

the restrictions imposed by this lock-up agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless the Representatives waive, in writing, such extension.

For the avoidance of doubt, nothing contained herein shall prevent the undersigned from or restrict the ability of the undersigned to (i) purchase shares of Common Stock or other securities of the Company or (ii) exercise any options or other convertible securities granted under any benefit plan of the Company; provided, that any shares of Common Stock received upon exercise of such options or other convertible securities shall be subject to the foregoing restrictions.

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.

THIS LOCK-UP AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
