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 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 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. 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 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 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 foregoing sentence shall not apply to the Securities to be sold hereunder. Notwithstanding the foregoing, if (1) during the last 17 days of the 30-day restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs or (2) prior to the expiration of the 30-day restricted period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of the 30-day restricted period, the restrictions imposed in this paragraph (j) 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.

(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.

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.

(m)REIT Qualification.

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

(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.

The Company covenants and agrees that (i) if the Charter Amendment is not so approved, it shall submit the Charter Amendment or, in its stead, an amendment to the Company's amended and restated certificate of incorporation providing for the authorization of at least an additional number of shares of Common Stock sufficient to issue shares of Common Stock equal to the Exchange Cap (as such term is defined in the General Disclosure Package), for approval at each of its subsequent annual meetings until so approved and (ii) promptly following the approval of the Charter Amendment (or such other amendment specified in clause (i) of this sentence), the Company shall reserve for future issuance a requisite number of shares of Common Stock so issuable upon conversion of the Series A Stock then outstanding. Upon stockholder approval of the Charter Amendment (or stockholder approval of such other amendment as described in the immediately preceding sentence) and the filing by the Company of an amendment to its amended and restated certificate of incorporation to reflect such amendment, the Common Stock so issuable upon conversion of the Series A Stock then outstanding will be duly authorized and, when issued upon conversion and surrender of the Series A Stock in accordance with the Certificate of Designation, will be validly issued, fully paid and nonassessable.

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), 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 third, ninth and tenth paragraphs, each relating to price, stabilization activities (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 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 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 and 7 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.

The Company acknowledges that the Underwriters' research analysts and research departments are required to be independent from its investment banking division and is subject to certain regulations and internal policies, and that Underwriter's research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by its research analysts and research department may be different from or inconsistent with the views or advice communicated to the Company by Underwriters' investment banking division. The Company acknowledges that each Underwriter is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the Company and any other companies that may be the subject of the transactions contemplated by this Agreement.

Section 16.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, Affiliates, selling agents 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.

Special optional redemption: Upon the occurrence of a Change of Control, the Issuer may, at its option, redeem any or all of the shares of Series A Preferred Stock within 120 days after the first date on which such Change of Control occurred at a cash redemption price of $25.00 per share plus any accumulated and unpaid dividends to, but not including, the redemption date. If, prior to the Change of Control Conversion Date (as defined below), the Issuer has provided notice of its election to redeem some or all of the Series A Preferred Stock (whether pursuant to its optional redemption right or this special optional redemption right), the holders of Series A Preferred Stock will not have the conversion right described below under “Conversion rights” with respect to the shares of Series A Preferred Stock called for redemption.
Change of Control: Deemed to occur when, after the original issuance of the Series A Preferred Stock, the following have occurred and are continuing: (i) the acquisition by any person, including any syndicate or group deemed to be a “person” under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or series of purchases, mergers or other acquisition transactions of the Issuer's stock entitling that person to exercise more than 50% of the total voting power of all the Issuer's stock entitled to vote generally in the election of the Issuer's directors (except that such person will be deemed to have beneficial ownership of all securities that such person has the right to acquire, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent condition); and (ii) following the closing of any transaction referred to in clause (i) above, neither the Issuer nor the acquiring or surviving entity has a class of common securities (or American Depositary Receipts representing such securities) listed on the New York Stock Exchange (the “NYSE”), the NYSE Amex Equities (the “NYSE Amex”) or The NASDAQ Stock Market (“Nasdaq”), or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE Amex or Nasdaq.



Conversion rights: Upon the occurrence of a Change of Control, provided that the Common Stock Authorization has occurred at or prior to such Change of Control, each holder of Series A Preferred Stock will have the right (subject to the special optional redemption described above) to convert some or all of the Series A Preferred Stock held by such holder on the Change of Control Conversion Date into a number of shares of the Issuer's common stock per share of Series A Preferred Stock to be converted equal to the lesser of: l the quotient obtained by dividing (i) the sum of the $25.00 liquidation preference per share of the Series A Preferred Stock plus the amount of any accumulated and unpaid dividends thereon to, but not including, the Change of Control Conversion Date (unless the Change of Control Conversion Date is after a dividend record date and prior to the corresponding dividend payment date for the Series A Preferred Stock, in which case no additional amount for such accrued and unpaid dividends will be included in this sum) by (ii) the Common Stock Price (as defined below); and l 1.7100 (the “Share Cap”), subject to adjustments to the Share Cap for any splits, subdivisions or combinations of our common stock. The “Common Stock Authorization” consists of (1) the approval of an amendment by the Issuer's stockholders at the 2012 Annual Meeting, or any other amendment to the Issuer's amended and restated certificate of incorporation to increase the number of the Issuer's authorized shares of common stock by an amount in excess of the Exchange Cap (as defined below), whether at the Issuer's 2012 Annual Meeting or otherwise, and (2) the subsequent filing of such amendment to effect the increased number of authorized common shares provided for in such amendment. The “Common Stock Price” is (i) if the consideration to be received in the Change of Control by the holders of the Issuer's common stock is solely cash, the amount of cash consideration per share of the Issuer's common stock or (ii) if the consideration to be received in the Change of Control by holders of the Issuer's common stock is other than solely cash (x) the average of the closing sale prices per share of the Issuer's common stock (or, if no closing sale price is reported, the average of the closing bid and ask prices per share or, if more than one in either case, the average of the average closing bid and the average closing ask prices per share) for the ten consecutive trading days immediately preceding, but not including, the date on which such Change of Control occurred as reported on the principal U.S. securities exchange on which the Issuer's common stock is then traded, or (y) the average of the last quoted bid prices for the Issuer's common stock in the over-the-counter market as reported by Pink OTC Markets Inc. or similar organization for the ten consecutive trading days immediately preceding, but not including, the date on which such Change of Control occurred, if the Issuer's common stock is not then listed for trading on a U.S. securities exchange. The “Change of Control Conversion Date” is the date the Series A Preferred Stock is to be converted, which will be a business day selected by the Issuer that is no fewer than 20 days nor more than 35 days after the date on which the Issuer provides the required notice of the occurrence of a Change of Control to the holders of Series A Preferred Stock. The “Exchange Cap” is the aggregate number of shares of the Issuer's common stock (or equivalent alternative conversion consideration, as applicable) issuable or deliverable, as applicable, in connection with the exercise of the Change of Control Conversion Right. For the avoidance of doubt, subject to certain adjustments, the Exchange Cap will not exceed 10,260,000 shares of the Issuer's common stock (or equivalent alternative conversion consideration, as applicable), subject to proportionate increase to the extent the underwriters' over-allotment option to purchase additional shares of Series A Preferred Stock is exercised, not to exceed 11,799,000 shares of the Issuer's common stock in total (or equivalent cash, securities or other property or assets (including any combination thereof), as applicable).
