BEAR, STEARNS & CO. INC.
As Representative of the several underwriters, c/o Bear, Stearns & Co. Inc.
383 Madison Avenue
New York, NY 10179

Ladies and Gentlemen:

Annaly Mortgage Management, Inc., a Maryland corporation (the "Company"), proposes to issue and sell to the underwriters named in SCHEDULE A annexed hereto (the "Underwriters"), for whom Bear, Stearns & Co. Inc. ("Bear Stearns") is acting as representative, an aggregate of 2,750,000 shares (the "Firm Shares") of 7.875% Series A cumulative redeemable preferred stock, $0.01 par value (liquidation preference $25.00 per share) (the "Series A Preferred Stock"), of the Company. In addition, solely for the purpose of covering over-allotments, the Company proposes to grant to the Underwriters the option to purchase from the Company up to an additional 412,500 shares of Series A Preferred Stock (the "Additional Shares"). The Firm Shares and the Additional Shares are hereinafter collectively sometimes referred to as the "Shares." The Shares are described in the Prospectus which is referred to below.

The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the "Securities Act"), with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-3 (File No. 333-105987), as amended, including a base prospectus, with respect to the Shares, and which incorporates by reference documents which the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the "Exchange Act"). The Company has prepared a prospectus supplement (the "Prospectus Supplement") to the base prospectus included as part of such registration statement setting forth the terms of the offering, sale and plan of distribution of the Shares and additional information concerning the Company and its business. The Company has furnished to Bear Stearns, for use by the Underwriters and by dealers, copies of one or more preliminary prospectuses, containing the base prospectus included as part of such registration statement, as supplemented by a preliminary Prospectus Supplement, and including the documents incorporated in such base prospectus by reference (each, a "Preliminary Prospectus"), relating to the Shares. Except where the context otherwise requires, such registration statement, as amended when it became effective, including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a Prospectus (as defined below) subsequently filed with the Commission pursuant to Rule 424(b) under the Securities Act and also including any other registration statement filed pursuant to Rule 462(b) under the Securities Act, collectively, are herein called the "Registration Statement," and the base prospectus, including all documents incorporated therein by reference, included in the Registration Statement, as supplemented by the Prospectus Supplement, in the form filed by the Company with the Commission pursuant to Rule 424(b) under the Securities Act on or before the second Business Day (as defined below) following the date of this Underwriting Agreement (the "Agreement") (or on such other day as the parties may mutually agree), is herein called the "Prospectus." Any reference herein to the Registration Statement, the Prospectus, any Preliminary Prospectus or any amendment or supplement thereto shall be deemed to refer to and include the


documents incorporated by reference therein, and any reference herein to the terms "amend," "amendment" or "supplement" with respect to the Registration Statement, the Prospectus or any Preliminary Prospectus shall be deemed to refer to and include the filing after the execution hereof of any document with the Commission deemed to be incorporated by reference therein. For purposes of this Agreement, all references to the Registration Statement, the Prospectus, any Preliminary Prospectus or to any amendment or supplement thereto shall be deemed to include any copy filed with the Commission pursuant to its Electronic Data Gathering Analysis and Retrieval System ("EDGAR"), and such copy shall be identical in content to any Prospectus or Preliminary Prospectus delivered to the Underwriters for use in connection with the offering of the Shares.

The Company and the Underwriters agree as follows:

1. SALE AND PURCHASE. Upon the basis of the warranties and representations and subject to the terms and conditions herein set forth, the Company agrees to issue and sell the Firm Shares to the several Underwriters, and each of the Underwriters, severally and not jointly, agrees to purchase from the Company the respective number of Firm Shares (subject to such adjustment as Bear Stearns may determine to avoid fractional shares) set forth opposite the name of such Underwriter in SCHEDULE A annexed hereto at a purchase price of $23.5668 per Share. The Company is advised by Bear Stearns that the Underwriters intend (i) to make a public offering of the Shares as soon as the Underwriters deem advisable after this Agreement has been executed and delivered and (ii) initially to offer the Firm Shares upon the terms set forth in the Prospectus. The Underwriters may from time to time increase or decrease the public offering price after the initial public offering to such extent as they may determine.

In addition, the Company hereby grants to the several Underwriters the option to purchase, and upon the basis of the warranties and representations and subject to the terms and conditions herein set forth, the Underwriters shall have the right to purchase, severally and not jointly, from the Company ratably in accordance with the number of Firm Shares to be purchased by each of them (subject to such adjustment as Bear Stearns shall determine to avoid fractional shares), all or a portion of the Additional Shares as may be necessary to cover over-allotments made in connection with the offering of the Firm Shares, at the same purchase price per share to be paid by the Underwriters to the Company for the Firm Shares. This option may be exercised by Bear Stearns on behalf of the several Underwriters at any time (but not more than once) on or before the thirtieth day following the date hereof, by written notice to the Company. Such notice shall set forth the aggregate number of Additional Shares as to which the option is being exercised and the date and time when the Additional Shares are to be delivered (such date and time being herein referred to as the "additional time of purchase"); PROVIDED, HOWEVER, that the additional time of purchase shall not be (i) earlier than the time of purchase (as defined below) or (ii) later than the tenth Business Day after the date on which the option shall have been exercised. The number of Additional Shares to be sold to each Underwriter shall be the number which bears the same proportion to the aggregate number of Additional Shares being purchased as the number of Firm Shares set forth opposite the name of such Underwriter on SCHEDULE A hereto bears to the aggregate number of Firm Shares (subject, in each case, to such adjustment as Bear Stearns may determine to eliminate fractional shares). As used herein "Business Day" shall mean a day on which the New York Stock Exchange (the "NYSE") is open for trading and commercial banks in the City of New York are open for business.

2. PAYMENT AND DELIVERY. Payment of the purchase price for the Firm Shares shall be made to the Company by federal funds wire transfer against delivery of the certificates for the Firm Shares to Bear Stearns through the facilities of the Depository Trust Company ("DTC") for the respective accounts of the Underwriters. Such payment and delivery shall be made at 10:00 A.M., New York City time, on October 19, 2004 (unless another time shall be agreed to by Bear Stearns and the Company or unless postponed in accordance with the provisions of Section 8 hereof). The time at which such payment and delivery are actually made is herein sometimes called the "time of purchase." Certificates for the Firm

2

Shares shall be delivered to Bear Stearns, through the facilities of DTC, in definitive form in such names and in such denominations as Bear Stearns shall specify no later than the second Business Day preceding the time of purchase. For the purpose of expediting the checking of the certificates for the Firm Shares by Bear Stearns, the Company agrees to make such certificates available to Bear Stearns for such purpose at least one full Business Day preceding the time of purchase.

Payment of the purchase price for the Additional Shares shall be made at the additional time of purchase in the same manner and at the same office as the payment for the Firm Shares. Certificates for the Additional Shares shall be delivered to Bear Stearns, through the facilities of DTC, in definitive form in such names and in such denominations as Bear Stearns shall specify no later than the second Business Day preceding the additional time of purchase. For the purpose of expediting the checking of the certificates for the Additional Shares by Bear Stearns, the Company agrees to make such certificates available to Bear Stearns for such purpose at least one full Business Day preceding the additional time of purchase.

3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents and warrants to each of the Underwriters that:

The Registration Statement has been filed with the Commission and has been declared effective under the Securities Act.

The Prospectus Supplement has been or will be so prepared and will be filed pursuant to Rule 424(b) of the Securities Act on or before the second Business Day following the date of this Agreement or on such other day as the parties may mutually agree. The Preliminary Prospectus, at the time of filing thereof, conformed in all material respects to the requirements of the Securities Act.

The Company has not distributed any offering material in connection with the offering or sale of the Shares other than the Registration Statement, the Preliminary Prospectus, the Prospectus or any other materials, if any, permitted by the Securities Act.

(b) Each part of the Registration Statement, when such part became or becomes effective or was or is filed with the Commission, and the Prospectus and any amendment or supplement thereto, on the date of filing thereof with the Commission and at the time of purchase and, if applicable, at the additional time of purchase, conformed or will conform in all material respects with the requirements of the Securities Act. Each part of the Registration Statement, when such part became or becomes effective or was or is filed with the Commission, did not or will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus and any amendment or supplement thereto, on the date of filing thereof with the Commission and at the time of purchase and, if applicable, at the additional time of purchase, did not or will not include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that the foregoing shall not apply to statements in, or omissions from, any such document in reliance upon, and in conformity with, written information concerning the Underwriters that was furnished in writing to the Company by Bear Stearns, on behalf of the several Underwriters, specifically for use in the preparation thereof.

3

As of the date of this Agreement, the Company has no plan or intention to materially alter (i) its capital investment policy or (ii) except in accordance with its capital investment policy, the percentage of its investment portfolio that is invested in (A) mortgage-backed securities which are guaranteed, as to payments of principal and interest, by either the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association or the Government National Mortgage Association and (B) debentures which are issued by the Federal Home Loan Bank, Federal Home Loan Mortgage Corporation or Federal National Mortgage Association. The Company has good and marketable title to all of the properties and assets owned by it, in each case free and clear of any security interests, liens, encumbrances, equities, claims and other defects (except for any security interest, lien, encumbrance or claim that may otherwise exist under any applicable repurchase agreement), except such as do not have a Material Adverse Effect and do not interfere with the use made or proposed to be made of such property or asset by the Company, and except as described in or contemplated by the Prospectus. The Company owns no real property. Any real property and buildings held under lease by the Company are held under valid, existing and enforceable leases, with such exceptions as are disclosed in the Prospectus or are not material and do not interfere with the use made or proposed to be made of such property and buildings by the Company.

(dd) The Company has filed all federal and state income and franchise tax returns required to be filed on or prior to the date hereof and has paid taxes shown as due thereon (or that are otherwise due and payable), other than taxes which are being contested in good faith and for which adequate reserves have been established in accordance with generally accepted accounting principles. The Company has no knowledge, after due inquiry, of any tax deficiency which has been asserted or threatened against the Company. To the knowledge of the Company, there are no tax returns of the Company that are currently being audited by federal, state or local taxing authorities or agencies which would have a Material Adverse Effect.

(ee) The Company owns or possesses adequate license or other rights to use all patents, trademarks, service marks, trade names, copyrights, software and design licenses, trade secrets, manufacturing processes, other intangible property rights and know-how (collectively, "Intangibles") necessary to entitle the Company to conduct its business as described in the Prospectus, and the Company has not received notice of infringement of or conflict with (and the Company knows of no such infringement of or conflict with) asserted rights of others with respect to any Intangibles which could have a Material Adverse Effect.

(ff) The Company maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management's general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles as applied in the United States and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management's general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

8

(gg) The Company has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-14 and 15d-14 under the Exchange Act); such disclosure controls and procedures are designed to ensure that material information relating to the Company is made known to the Company's Chief Executive Officer and its Chief Financial Officer, and such disclosure controls and procedures are effective to perform the functions for which they were established; any significant material weaknesses in internal controls have been identified for the Company's Chief Executive Officer and its Chief Financial Officer; and since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls.

(hh) The Company is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the business in which it is engaged. The Company has no reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

(ii) The Company is not in violation, and has not received notice of any violation with respect to, any applicable environmental, safety or similar law applicable to the business of the Company. The Company has received all permits, licenses or other approvals required of them under applicable federal and state occupational safety and health and environmental laws and regulations to conduct its business, and the Company is in compliance with all terms and conditions of any such permit, license or approval, except any such violation of law or regulation, failure to receive required permits, licenses or other approvals or failure to comply with the terms and conditions of such permits, licenses or approvals which could not, singly or in the aggregate, have a Material Adverse Effect.

(jj) The Company has not incurred any liability for any finder's fees or similar payments in connection with the transactions herein contemplated, except as may otherwise exist with respect to the Underwriters pursuant to this Agreement.

(kk) There are no existing or, to the knowledge of the Company, threatened labor disputes with the employees of the Company which are likely to have individually or in the aggregate a Material Adverse Effect.

(ll) Neither the Company nor, to the knowledge of the Company, any employee or agent of the Company, has made any payment of funds of the Company or received or retained any funds in violation of any law, rule or regulation or of a character required to be disclosed in the Prospectus. No relationship, direct or indirect, exists between or among the Company, on the one hand, and the directors, officers and stockholders of the Company, on the other hand, which is required by the Securities Act to be described in the Registration Statement and the Prospectus that is not so described.

(mm) The Company, since its date of inception, has been, and upon the sale of the Shares will continue to be, organized and operated in conformity with the requirements for qualification and taxation as a "real estate investment trust" (a "REIT") under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the "Code"), for all taxable years commencing with its taxable year ended December 31, 1997. The proposed method of operation of the Company as described in the Prospectus will enable the Company to continue to meet the requirements for qualification and taxation as a REIT under the Code, and no actions have been taken (or not taken which are required to be taken) which would cause such qualification to be lost. The Company intends to continue to operate in a manner which would permit it to qualify as a REIT under the Code. The Company has no intention of changing its operations or engaging in activities which would cause it to fail to qualify, or make economically undesirable its continued qualification, as a REIT.

9

(nn) The Company is not and, after giving effect to the offering and sale of the Shares, will not be an "investment company" or an entity "controlled" by an "investment company," as such terms are defined in the Investment Company Act of 1940, as amended (the "Investment Company Act").

(oo) No relationship, direct or indirect, exists between or among the Company, on the one hand, and the directors, officers, stockholders or directors of the Company, on the other hand, which is required by the rules of the NASD to be described in the Registration Statement and the Prospectus which is not so described.

(pp) The Company has not, directly or indirectly, including through any subsidiary, extended credit, arranged to extend credit, or renewed any extension of credit, in the form of a personal loan, to or for any director or executive officer of the Company, or to or for any family member or affiliate of any director or executive officer of the Company.

(qq) Neither the Company nor any of the subsidiaries nor, to the Company's knowledge, any employee or agent of the Company or the subsidiaries has made any payment of funds of the Company or the subsidiaries or received or retained any funds in violation of any law, rule or regulation, which payment, receipt or retention of funds is of a character required to be disclosed in the Registration Statement or the Prospectus.

(rr) The Company is in compliance with all presently applicable provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated thereunder (the "Sarbanes-Oxley Act") and is actively taking steps to ensure that it will be in compliance with other applicable provisions of the Sarbanes-Oxley Act upon the effectiveness of such provisions.

(a) The Company will furnish such information as may be required and otherwise will cooperate in qualifying the Shares for offering and sale under the securities or blue sky laws of such jurisdictions (both domestic and foreign) as Bear Stearns may designate and to maintain such qualifications in effect so long as required for the distribution of the Shares, provided that the Company shall not be required to qualify as a foreign corporation or to consent to the service of process under the laws of any such jurisdiction (except service of process with respect to the offering and sale of the Shares). The Company will promptly advise Bear Stearns of the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(b) The Company will prepare the Prospectus in a form approved by the Underwriters and file such Prospectus with the Commission pursuant to Rule 424(b) under the Securities Act not later than 10:00 A.M. (New York City time), on or before the second Business Day following the date of this Agreement or on such other day as the parties may mutually agree and to furnish promptly (and with respect to the initial delivery of such Prospectus, not later than 10:00
A.M. (New York City time) on or before the second Business Day following the date of this Agreement or on such other day as the parties may mutually agree) to the Underwriters copies of the Prospectus (or of the Prospectus as amended or supplemented if the Company shall have made any amendments or supplements thereto after the effective date of the Registration Statement) in such quantities and at such locations as the Underwriters may reasonably request for the purposes contemplated by the Securities Act, which the Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the version created to be transmitted to the Commission for filing via EDGAR, except to the extent permitted by Regulation S-T.

10

(c) The Company will advise Bear Stearns immediately, confirming such advice in writing, of (i) the receipt of any comments from the Commission relating to any filing of the Company under the Securities Act or the Exchange Act, (ii) any request by the Commission for amendments or supplements to the Registration Statement or the Prospectus or for additional information with respect thereto, (iii) 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 the Prospectus, (iv) the suspension of the qualification of the Shares for offering or sale in any jurisdiction, (v) the initiation, threatening or contemplation of any proceedings for any of such purposes and, if the Commission or any other governmental agency or authority should issue any such order, the Company will make every reasonable effort to obtain the lifting or removal of such order as soon as possible. The Company will advise Bear Stearns promptly of any proposal to amend or supplement the Registration Statement or the Prospectus including by filing any documents that would be incorporated therein by reference and to file no such amendment or supplement to which Bear Stearns shall object to in writing.

If within the time during which a Prospectus relating to the Shares is required to be delivered under the Securities Act any event shall occur or condition shall exist which, in the reasonable opinion of the Company, Bear Stearns or their respective counsel, would require the making of any change in the Prospectus then being used, or in the information incorporated by reference therein, so that the Prospectus would not include an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend or supplement the Prospectus to comply with any law, the Company will promptly prepare and furnish to the Underwriters copies of the proposed amendment or supplement before filing any such amendment or supplement with the Commission and thereafter promptly furnish, at the Company's own expense, to the Underwriters and to dealers copies in such quantities and at such locations as Bear Stearns may from time to time reasonably request of an appropriate amendment to the Registration Statement or supplement to the Prospectus so that the Prospectus as so amended or supplemented will not, in the circumstances when it is so delivered, be misleading or so that the Prospectus will comply with the law.

14

In the event that the letters referred to above set forth any such changes, decreases or increases, it shall be a further condition to the obligations of the Underwriters that (i) such letters shall be accompanied by a written explanation of the Company as to the significance thereof, unless Bear Stearns deem such explanation unnecessary, and (ii) such changes, decreases or increases do not, in the sole judgment of Bear Stearns, make it impractical or inadvisable to proceed with the purchase and delivery of the Shares as contemplated by the Registration Statement and the Prospectus.

(c) Bear Stearns shall have received at the time of purchase and at the additional time of purchase, as the case may be, the favorable opinion of Clifford Chance US LLP, counsel for the Underwriters, dated the time of purchase or the additional time of purchase, as the case may be, substantially in the form of EXHIBIT B hereto.

7. TERMINATION. The obligations of the several Underwriters hereunder shall be subject to termination in the absolute discretion of Bear Stearns, at any time prior to the time of purchase or, if applicable, the additional time of purchase, (i) if any of the conditions specified in Section 6 shall not have been fulfilled when and as required by this Agreement to be fulfilled, (ii) if any material adverse and unfavorable change occurs (financial or otherwise), or any development involving a material adverse and unfavorable change occurs (financial or otherwise) (in each case, other than as disclosed in, or incorporated by reference into, the Registration Statement and the Prospectus (exclusive of any supplement thereto)), in the operations, business, net worth, condition or prospects of the Company, or a material change in management of the Company occurs, whether or not arising in the ordinary course of business, which would, in the sole judgment of Bear Stearns, make it impracticable to market the Shares, (iii) if the United States shall have declared war in accordance with its constitutional processes or there has occurred an outbreak or escalation of hostilities or other national or international calamity or crisis or change in economic, political or other conditions the effect of which on the financial markets of the United States is such as to make it, in the sole judgment of Bear Stearns, impracticable or inadvisable to market the Shares or enforce contracts for the sale of the Shares, (iv) if trading in any securities of the Company has been suspended by the Commission or by the NYSE, or if trading generally on the NYSE has been suspended (including an automatic halt in trading pursuant to market-decline triggers other than those in which solely program trading is temporarily halted), or limitations on or minimum prices for trading (other than limitations on hours or numbers of days of trading) shall have been fixed, or maximum ranges for prices for securities have been required, by such exchange or the NASD or Nasdaq or by order of the Commission or any other governmental authority, (v) if a banking moratorium shall have been declared by New York or United States authorities or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States,
(vi) if there shall have occurred any downgrading, or any notice or announcement shall have been given or made of (a) any intended or potential downgrading or
(b) any review or possible change that does not indicate an improvement, in the rating accorded any securities of or guaranteed by the Company by any "nationally recognized statistical rating organization," as that term is defined in Rule 436(g)(2) under the Securities Act, (vii) if any federal or state statute, regulation, rule or order of any court or other governmental authority has been enacted, published, decreed or otherwise promulgated which, in the reasonable opinion of Bear Stearns, materially adversely affects or will materially adversely affect the business or operations of the Company, or (viii) if any action has been taken by any federal, state or local government or agency in respect of its monetary or fiscal affairs which, in the reasonable opinion of Bear Stearns, has a material adverse effect on the securities markets in the United States.

If Bear Stearns elects to terminate this Agreement as provided in this
Section 7, the Company and each other Underwriter shall be notified promptly by telephone, which shall be promptly confirmed by facsimile.

If the sale to the Underwriters of the Shares, as contemplated by this Agreement, is not carried out by the Underwriters for any reason permitted under this Agreement or if such sale is not carried out because the Company shall be unable to comply with any of the terms of this Agreement, the Company

16

shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 4(o), 5, 9 and 10 hereof), and the Underwriters shall be under no obligation or liability to the Company under this Agreement (except to the extent provided in Sections 9 and 10 hereof) or to one another hereunder.

8. INCREASE IN UNDERWRITERS' COMMITMENTS. If any Underwriter shall default in its obligation under this Agreement to take up and pay for the Shares to be purchased by it under this Agreement (otherwise than for reasons sufficient to justify the termination of this Agreement under the provisions of
Section 7 hereof), Bear Stearns shall have the right, within 36 hours after such default, 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 Shares which such Underwriter shall have agreed but failed to take up and pay for (the "Defaulted Shares"). Absent the completion of such arrangements within such 36 hour period, (i) if the total number of Defaulted Shares does not exceed 10% of the total number of Shares to be purchased at the time of purchase or the additional time of purchase, as the case may be, each non-defaulting Underwriter shall take up and pay for (in addition to the number of Shares which it is otherwise obligated to purchase on such date pursuant to this Agreement) the number of Shares agreed to be purchased by all such defaulting Underwriters in such amount or amounts as Bear Stearns may designate with the consent of each Underwriter so designated or, in the event no such designation is made, such Shares shall be taken up and paid for by all non-defaulting Underwriters pro rata in proportion to the aggregate number of Firm Shares set opposite the names of such non-defaulting Underwriters in SCHEDULE A; and (ii) if the total number of Defaulted Shares exceeds 10% of such total number of Shares to be purchased at the time of purchase or the additional time of purchase, as the case may be, and if neither the non-defaulting Underwriters nor the Company shall make arrangements within the five Business Day period from the date of default for the purchase of such Defaulted Shares, Bear Stearns may terminate this Agreement by notice to the Company, without liability of any party to any other party except that the provisions of Sections 4(o), 5, 9 and 10 shall at all times be effective and shall survive such termination. Nothing in this paragraph, and no action taken hereunder, shall relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

Without relieving any defaulting Underwriter from its obligations hereunder, the Company agrees with the non-defaulting Underwriters that they will not sell any Shares hereunder unless all of the Shares are purchased by the Underwriters (or by substituted Underwriters selected by Bear Stearns with the approval of the Company or selected by the Company with Bear Stearns' approval).

If a new Underwriter or Underwriters are substituted for a defaulting Underwriter or Underwriters in accordance with the foregoing provisions, the Company or Bear Stearns shall have the right to postpone the time of purchase or the additional time of purchase, as the case may be, for a period not exceeding five Business Days from the date of substitution in order that any necessary changes in the Registration Statement and the Prospectus and other documents may be effected.

The term Underwriter as used in this Agreement shall refer to and include any Underwriter substituted under this Section 8 with like effect as if such substituted Underwriter had originally been named in SCHEDULE A.

9. INDEMNIFICATION.

(a) The Company shall indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, (i) against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys' fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim

17

whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, as originally filed or any amendment thereof, or any related Preliminary Prospectus or the Prospectus, or in any supplement thereto or amendment thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the case of any Preliminary Prospectus or the Prospectus, in the light of the circumstances under which such statements were made, not misleading or (ii) against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys' fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation) arising out of a breach by the Company of the representations and warranties contained in Section 3 of this Agreement; provided, however, that the Company will not be liable in any such case to the extent but only to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through Bear Stearns expressly for use therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have, including but not limited to other liability under this Agreement.

(b) Each Underwriter severally agrees to indemnify and hold harmless the Company, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys' fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Exchange Act, the Securities Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, as originally filed or any amendment thereof, or any related Preliminary Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through Bear Stearns specifically for use therein; provided, however, that in no case shall any Underwriter be liable or responsible for any amount in excess of the underwriting discount applicable to the Shares to be purchased by such Underwriter hereunder. This indemnity will be in addition to any liability which the Underwriters may otherwise have, including but not limited to other liability under this Agreement.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of any claims or the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the claim or the commencement thereof (but the failure so to notify an indemnifying party shall not relieve the indemnifying party from any liability which it may have under this Section 9 to the extent that it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability that such indemnifying party may have otherwise than on

18

account of the indemnity agreement hereunder). In case any such claim or action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate, at its own expense in the defense of such action, and to the extent it may elect 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, that counsel to the indemnifying party shall not (except with the written consent of the indemnified party) also be counsel to the indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, (iii) the indemnifying party does not diligently defend the action after assumption of the defense, or (iv) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. In no event shall the indemnifying party be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from its own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened claim, investigation, action or proceeding in respect of which indemnity or contribution may be or could have been sought by an indemnified party under this Section 9 or Section 10 hereof (whether or not the indemnified party is an actual or potential party thereto), unless (x) such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such claim, investigation, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or any failure to act, by or on behalf of the indemnified party, and
(y) the indemnifying party confirms in writing its indemnification obligations hereunder with respect to such settlement, compromise or judgment.

10. CONTRIBUTION. In order to provide for contribution in circumstances in which the indemnification provided for in Section 9 hereof is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company and each Underwriter shall contribute to the aggregate losses, claims, damages, liabilities and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting in the case of losses, claims, damages, liabilities and expenses suffered by the Company, any contribution received by the Company from persons, other than the Underwriters, who may also be liable for contribution, including persons who control the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company) as incurred to which the Company and the Underwriters may be subject, in such proportions as is appropriate to reflect the relative benefits received by the Company and the Underwriters from the offering and sale of the Shares or, if such allocation is not permitted by applicable law, in such proportions as are appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same proportion as (x) the total proceeds from the offering and sale of the Shares (net of

19

underwriting discounts and commissions but before deducting expenses) received by the Company bears to (y) the underwriting discount or commissions received by the Underwriters, in each case as set forth in the Prospectus. The relative fault of each of the Company and of the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or 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 10 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 10. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 10 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 judicial, regulatory or other legal or 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 10, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the discounts and commissions applicable to the Shares underwritten by such Underwriter and distributed to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 10, each person, if any, who controls any Underwriter within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to clauses
(i) and (ii) of the immediately preceding sentence. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 10 or otherwise. The Underwriters' respective obligations to contribute pursuant to this Section 10 are several in proportion to the number of Shares set forth opposite their respective names in Schedule A hereto and not joint.

11. INFORMATION FURNISHED BY THE UNDERWRITERS. The statements set forth in the last paragraph on the cover page of the Prospectus Supplement, the statement set forth in the last sentence of the third paragraph under the caption "Risk Factors", and the statements set forth in the sixth, ninth, eleventh and twelfth paragraphs under the caption "Underwriting" in the Prospectus Supplement constitute the only information furnished by or on behalf of the Underwriters as such information is referred to in Sections 3 and 9 hereof.

12. NOTICES. Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram and, if to the Underwriters, shall be sufficient in all respects if delivered or sent to Bear, Stearns & Co. Inc., 383 Madison Avenue, New York, New York 10179, Attention: Erik Friedman; and if to the Company, shall be sufficient in all respects if delivered or sent to the Company at the offices of the Company at 1211 Avenue of the Americas, Suite 2902, New York, New York 10036, Attention:

13. GOVERNING LAW; CONSTRUCTION. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (a "Claim"), directly or indirectly, shall be governed by, and construed in accordance with, the laws of the State of New York. The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

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

15. PARTIES AT INTEREST. The Agreement herein set forth has been and is made solely for the benefit of the Underwriters, the Company and to the extent provided in Sections 9 and 10 hereof the controlling Persons, directors and officers referred to in such Sections, and their respective successors, assigns, heirs, pursuant representatives and executors and administrators. No other Person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement.

16. COUNTERPARTS. This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

17. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the Underwriters and the Company and their successors and assigns and any successor or assign of any substantial portion of the Company's and any of the Underwriters' respective businesses and/or assets.

21

If the foregoing correctly sets forth the understanding among the Company and the Underwriters, please so indicate in the space provided below for the purpose, whereupon this letter and your acceptance shall constitute a binding agreement among the Company and the Underwriters, severally.

Very truly yours,

OPINION OF MCKEE NELSON LLP

1. The Company has been duly incorporated and is validly existing and in good standing under the laws of the State of Maryland. The Company is duly qualified or registered as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification or registration is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or register or be in good standing would not have a Material Adverse Effect.

2. The Company has the corporate power and authority to own, lease and operate its properties and conduct its business as described in the Prospectus and to enter into and perform its obligations under or as contemplated by the Underwriting Agreement.

3. The Underwriting Agreement has been duly authorized, executed, and delivered by the Company.

4. The Shares have been duly authorized by the Company for issuance and sale to the Underwriters pursuant to the Underwriting Agreement and, when issued and delivered by the Company pursuant to the Underwriting Agreement against payment of the consideration set forth therein, will be validly issued, fully paid and non-assessable and no holder of the Shares is or will be subject to personal liability, under the General Corporation Law of the State of Maryland (the "MGCL") or the charter or by-laws of the Company, by reason of being a holder.

5. All issued and outstanding shares of capital stock of the Company are validly issued, fully paid, and non-assessable, and conform in all material respects with the description thereof contained in the Prospectus. The Shares when issued and outstanding will conform in all material respects with the description thereof contained in the Prospectus. The relative rights, preferences, interests and powers of the Shares offered pursuant to the Underwriting Agreement, as set forth in the Articles Supplementary relating thereto, are valid under the MGCL.

6. The issuance of the Shares is not subject to preemptive or other similar rights of any stockholder of the Company arising by operation of the MGCL or under the charter or by-laws of the Company, or, to our knowledge, any contractual preemptive rights, resale rights, rights of first refusal or similar rights. Except as disclosed in the Registration Statement and the Prospectus, there is no outstanding option, warrant or other right calling for the issuance of, and, to the knowledge of such counsel, no commitment, plan or arrangement to issue, any shares of capital stock of the Company or any security convertible into, exercisable for, or exchangeable for shares of capital stock of the Company. No holder of any security of the Company has the right to have any security owned by such holder included for registration in the Registration Statement.

7. The form of the certificate used to evidence the Series A Preferred Stock of the Company complies in all material respects with all applicable requirements of the MGCL and with the applicable requirements of the charter and by-laws of the Company and complies with all the applicable requirements of NYSE.

8. The information in the Prospectus under the caption "Description of Stock" and in the Prospectus Supplement under the caption "Description of Series A Preferred Stock," to the extent that

Ex. A-1


such information constitutes summaries of legal matters under the MGCL or of provisions of the Company's charter or by-laws, have been reviewed by us and are correct in all material respects. The information in the Prospectus under the caption "Federal Income Tax Considerations," and in the Prospectus Supplement under caption "Federal Income Tax Consequences," to the extent that such information constitutes a summary of legal matters, documents or proceedings referred to therein, have been reviewed by us and fairly present the information called for with respect to such legal matters, documents and proceedings in all material respects as required by the Securities Act of 1933 (the "1933 Act"), the rules and regulations of the Securities and Exchange Commission (the "Commission") under the 1933 Act (the "1933 Act Regulations"), the Securities Exchange Act of 1934, as amended (the "1934 Act") and the rules and regulations of the Commission under the 1934 Act (the "1934 Act Regulations").

9. The Company satisfies the registrant eligibility requirements for the use of Form S-3 under the 1933 Act set forth in General Instruction I.A. to such Form; the transactions contemplated by the Underwriting Agreement satisfy the transaction eligibility requirements for the use of such Form set forth in General Instruction I.B.1 to such Form; and the Shares have been registered under the Registration Statement in compliance with such requirements.

10. The Registration Statement and the Prospectus (in each case other than (A) the financial statements and supporting schedules and other financial or statistical data included or incorporated by reference therein or omitted therefrom as to which we express no opinion and (B) except as expressed in our opinion in paragraph (11) below, the documents incorporated therein), as of their respective effective dates, as the case may be, each complied, and as of the date hereof each comply, as to form in all material respects to the applicable requirements of the 1933 Act and the 1933 Act Regulations.

11. The annual report on Form 10-K for the year ended December 31, 2003 and the proxy statement contained in the Form S-4 filed with the Commission on March 10, 2004, incorporated by reference in the Registration Statement (other than the financial statements and supporting schedules and other financial data included therein, as to which we express no opinion), when they were filed with the Commission (or, if later, upon filing of an amendment thereto) complied as to form in all material respects with the requirements of the 1934 Act and the 1934 Act Regulations.

12. The Registration Statement has been declared effective under the 1933 Act; the Prospectus has been filed pursuant to Rule 424(b) of the 1933 Act Regulations in the manner and within the time period required by Rule 424(b); and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

13. To our knowledge, no consent, approval, authorization, or other order of any federal regulatory body, federal administrative agency or other federal governmental body of the United States of America or any state regulatory body, state administrative agency or other state governmental body of the State of Maryland is required under Applicable Laws for the issuance and sale of the Shares to the Underwriters as contemplated by the Underwriting Agreement or the public offering of the Shares as contemplated by the Prospectus.

14. The issuance and sale of the Shares to the Underwriters as contemplated by the Underwriting Agreement and consummation of the transactions contemplated thereby do not and will not conflict with or result in a breach or violation of any of the terms and provisions of, or constitute a default under (A) any indenture, mortgage, deed of trust, lease, repurchase agreement or other agreement, known to us, to which the Company is a party or is bound, except for such for such violations, conflicts, breaches, defaults, liens, charges, or encumbrances that would not result in a Material Adverse Effect, (B) the charter or bylaws of the Company, (C) Applicable Laws, (D) the Investment Company Act of

Ex. A-2


1940, as amended (the "1940 Act"), or (E) or any judgment, decree, order, rule, or regulation, known to us, of any court, other governmental authority, or arbitrator having jurisdiction over the Company, except for such for such violations, conflicts, breaches, defaults, liens, charges, or encumbrances that would not result in a Material Adverse Effect.

15. The Company is not in violation of its charter or by-laws, and, to our knowledge, no default by the Company exists in the due performance or observance of any material obligation, agreement, covenant, or condition contained in any contract, indenture, mortgage, loan agreement, note, lease, repurchase agreement, other agreement, or instrument that is described or referred to in the Registration Statement or the Prospectus or filed or incorporated by reference as an exhibit to the Registration Statement, except, in each case above, for such for such violations, conflicts, breaches, defaults, liens, charges, or encumbrances that would not result in a Material Adverse Effect.

16. To our knowledge, there are no legal or governmental proceedings pending or threatened which are required to be disclosed in the Registration Statement or the Prospectus but are not so disclosed.

17. The Company is not, and the transactions contemplated by the Underwriting Agreement will not cause the Company to become an "investment company" or an entity "controlled" by an "investment company" under the 1940 Act.

18. For all taxable years commencing with its taxable year ended December 31, 1997, the Company has been, and upon the sale of Shares will continue to be, organized and operated in conformity with the requirements for qualification and taxation as a "real estate investment trust" (a "REIT") under
Section 856 through 860 of the Internal Revenue Code of 1986, as amended (the "Code"). The Company's proposed method of operation will enable the Company to continue to meet the requirements for qualification and taxation as a REIT under the Code, and no actions have been taken (or not taken which are required to be taken) which would cause such qualification to be lost. The disclosure contained in the Prospectus under the caption "Federal Income Tax Considerations," to the extent such information constitutes a summary of the United States federal income tax laws and legal conclusions referred to therein, is accurate in all material respects and fairly summarizes the federal income tax laws referred to therein.

In acting as counsel to the Company, we have participated in conferences with officers and other representatives of the Company, the independent public accountants for the Company, and your representatives, at which conferences the contents of the Registration Statement and the Prospectus, and related matters were discussed. Although we are not passing upon or assuming responsibility for the accuracy, completeness or fairness of the statements included or incorporated by reference in the Registration Statement, the Prospectus, or the Incorporated Documents (as defined below) and have made no independent check or verification thereof (except as set forth in paragraphs eight, ten and eighteen above), nothing has come to our attention which has led us to believe that the Registration Statement, at the time the Registration Statement became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that the Prospectus Supplement, as of its date or on the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except in each case that we express no belief and make no statement with respect to financial statements and schedules and other financial or statistical data included or incorporated by reference in or omitted from the Registration Statement, the Prospectus, or the Incorporated Documents. As used herein, the term "Incorporated Documents," when used with respect to the Registration Statement or the Prospectus as of any date, means the documents incorporated or deemed to be incorporated by reference in the

Ex. A-3


Registration Statement or the Prospectus, as the case may be, as of such date pursuant to Item 12 of Form S-3.

Ex. A-4


EXHIBIT B

OPINION OF CLIFFORD CHANCE US LLP

1. The Underwriting Agreement has been duly authorized, executed and delivered by the Underwriters.

2. The Shares have been duly authorized and, when issued and delivered to and paid for by the Underwriters, will be duly and validly and issued and will be fully paid and non-assessable.

3. The Shares conform to the description thereof contained in the Registration Statement and the Prospectus.

4. The Registration Statement and the Prospectus (except as to the financial statements and schedules and other financial and statistical data contained or incorporated by reference therein, as to which we express no opinion) comply as to form in all material respects with the requirements of the Securities Act.

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

In addition, we have reviewed the Registration Statement and the Prospectus and participated in the preparation of the Prospectus Supplement and in conferences with officers and other representatives of and counsel to the Company, representatives of the independent public accountants for the Company and representatives of the Underwriters at which the contents of the Registration Statement and the Prospectus and related matters were discussed and, we have reviewed certain corporate records, documents and proceedings, and on the basis of the foregoing, nothing has come to our attention that leads us to believe that the Registration Statement, at the time such Registration Statement became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading or that the Prospectus, as of the date of the Underwriting Agreement or the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (it being understood that we express no belief with respect to the financial statements, financial schedules and other financial data included or incorporated by reference in the Registration Statement or the Prospectus).

The limitations inherent in the independent verification of factual matters and the character of determinations involved in the preparation of a disclosure document are such, however, that we do not assume any responsibility for the accuracy, completeness, or fairness of the statements contained in the Registration Statement or the Prospectus or any amendments or supplements thereto (including any of the documents incorporated by reference therein).

(a) Holders of the then outstanding shares of Series A Preferred Stock shall be entitled to receive, when and as authorized by the Board of Directors, out of funds legally available for the payment of dividends, cumulative preferential cash dividends at the rate of 7.875% of the $25.00 liquidation preference per annum (equivalent to a fixed annual amount of $1.96875 per share). Such dividends shall be cumulative from the first date on which any Series A Preferred Stock is issued and shall be payable quarterly in arrears on or before March 31, June 30, September 30, and December 31 of each year or, if not a business day, the next succeeding business day (each, a "Dividend Payment Date"). Any dividend payable on the Series A Preferred Stock

1

for any partial dividend period will be computed on the basis of a 360-day year consisting of twelve 30-day months (it being understood that the dividend payable on June 30, 2004 will be for less than the full quarterly dividend period). Dividends will be payable to holders of record as they appear in the stock records of the Corporation at the close of business on the applicable record date, which shall be the first day of the calendar month on which the applicable Dividend Payment Date falls or on such other date designated by the Board of Directors of the Corporation for the payment of dividends that is not more than 30 nor less than 10 days prior to such Dividend Payment Date (each, a "Dividend Record Date").

(b) No dividends on shares of Series A Preferred Stock shall be declared by the Corporation or paid or set apart for payment by the Corporation at such time as the terms and provisions of any agreement of the Corporation, including any agreement relating to its indebtedness, prohibit such declaration, payment or setting apart for payment or provide that such declaration, payment or setting apart for payment would constitute a breach thereof or a default thereunder, or if such declaration or payment shall be restricted or prohibited by law.

(c) Notwithstanding the foregoing, dividends on the Series A Preferred Stock shall accrue whether or not the terms and provisions set forth in Section 3(b) hereof at any time prohibit the current payment of dividends, whether or not the Corporation has earnings, whether or not there are funds legally available for the payment of such dividends and whether or not such dividends are declared. Accrued but unpaid dividends on the Series A Preferred Stock will accumulate as of the Dividend Payment Date on which they first become payable.

(d) Except as provided in Section 3(e) below, unless full cumulative dividends on the Series A Preferred Stock have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof is set apart for payment for all past dividend periods and the then current dividend period, no dividends (other than in shares of Common Stock or in shares of any series of preferred stock ranking junior to the Series A Preferred Stock as to dividends and upon liquidation) shall be declared or paid or set aside for payment nor shall any other distribution be declared or made upon the Common Stock, or any preferred stock of the Corporation ranking junior to or on a parity with the Series A Preferred Stock as to dividends or upon liquidation, nor shall any shares of Common Stock, or any shares of preferred stock of the Corporation ranking junior to or on a parity with the Series A Preferred Stock as to dividends or upon liquidation be redeemed, purchased or otherwise acquired for any consideration (or any moneys be paid to or made available for a sinking fund for the redemption of any such shares) by the Corporation (except by conversion into or exchange for other capital stock of the Corporation ranking junior to the Series A Preferred Stock as to dividends and upon liquidation and except for transfers made pursuant to the provisions of Article XI of the Charter).

(e) When dividends are not paid in full (or a sum sufficient for such full payment is not so set apart) on the Series A Preferred Stock and the shares of any other series of preferred stock ranking on a parity as to dividends with the Series A Preferred Stock, all dividends declared upon the Series A Preferred Stock and any other series of preferred stock ranking on a parity as to dividends with the Series A Preferred Stock shall be declared pro rata so that the amount of dividends declared per

2

share of Series A Preferred Stock and such other series of preferred stock shall in all cases bear to each other the same ratio that accrued dividends per share on the Series A Preferred Stock and such other series of preferred stock (which shall not include any accrual in respect of unpaid dividends for prior dividend periods if such preferred stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on Series A Preferred Stock which may be in arrears.

(f) Any dividend payment made on shares of the Series A Preferred Stock shall first be credited against the earliest accrued but unpaid dividend due with respect to such shares which remains payable. Holders of the Series A Preferred Stock shall not be entitled to any dividend, whether payable in cash, property or stock in excess of full cumulative dividends on the Series A Preferred Stock as described above.

(4) LIQUIDATION PREFERENCE.

(a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation, the holders of shares of Series A Preferred Stock then outstanding are entitled to be paid out of the assets of the Corporation, legally available for distribution to its stockholders, a liquidation preference of $25.00 per share, plus an amount equal to any accrued and unpaid dividends to the date of payment, before any distribution of assets is made to holders of Common Stock or any series of preferred stock of the Corporation that ranks junior to the Series A Preferred Stock as to liquidation rights.

(b) In the event that, upon any such voluntary or involuntary liquidation, dissolution or winding up, the available assets of the Corporation are insufficient to pay the amount of the liquidating distributions on all outstanding shares of Series A Preferred Stock and the corresponding amounts payable on all shares of other classes or series of capital stock of the Corporation ranking on a parity with the Series A Preferred Stock in the distribution of assets, then the holders of the Series A Preferred Stock and all other such classes or series of capital stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled.

(c) After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series A Preferred Stock will have no right or claim to any of the remaining assets of the Corporation.

(d) Written notice of any such liquidation, dissolution or winding up of the Corporation, stating the payment date or dates when, and the place or places where, the amounts distributable in such circumstances shall be payable, shall be given by first class mail, postage pre-paid, not less than 30 nor more than 60 days prior to the payment date stated therein, to each record holder of the Series A Preferred Stock at the respective addresses of such holders as the same shall appear on the stock transfer records of the Corporation.

(e) The consolidation or merger of the Corporation with or into any other corporation, trust or entity or of any other corporation with or into the Corporation, or the sale, lease or conveyance of all or substantially all of the assets or business of the

3

Corporation, shall not be deemed to constitute a liquidation, dissolution or winding up of the Corporation.

(5) REDEMPTION.

(a) RIGHT OF OPTIONAL REDEMPTION. The Series A Preferred Stock is not redeemable prior to the five year anniversary of the issuance of the Series A Preferred Stock. However, in order to ensure that the Corporation remains a qualified real estate investment trust ("REIT") for federal income tax purposes, the Series A Preferred Stock will be subject to the provisions of Article XI of the Charter. Pursuant to Article XI, and without limitation of any provisions of such Article XI, Series A Preferred Stock, together with other equity stock of the Corporation, owned by a stockholder in excess of the Ownership Limit will automatically be transferred to a Trust (as defined in the Charter) for the benefit of a Beneficiary (as defined in the Charter). On and after the five year anniversary of the issuance of the Series A Preferred Stock, the Corporation, at its option and upon not less than 30 nor more than 60 days' written notice, may redeem shares of the Series A Preferred Stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends thereon to and including the date fixed for redemption (except as provided in Section 5(c) below), without interest. If less than all of the outstanding Series A Preferred Stock is to be redeemed, the Series A Preferred Stock to be redeemed shall be selected pro rata (as nearly as may be practicable without creating fractional shares) or by any other equitable method determined by the Corporation.

(b) LIMITATIONS ON REDEMPTION. Unless full cumulative dividends on all shares of Series A Preferred Stock shall have been, or contemporaneously are, declared and paid or declared and a sum sufficient for the payment thereof set apart for payment for all past dividend periods and the then current dividend period, no shares of Series A Preferred Stock shall be redeemed unless all outstanding shares of Series A Preferred Stock are simultaneously redeemed, and the Corporation shall not purchase or otherwise acquire directly or indirectly any shares of Series A Preferred Stock (except by exchange for capital stock of the Corporation ranking junior to the Series A Preferred Stock as to dividends and upon liquidation); provided, however, that the foregoing shall not prevent such action by the Board of Directors or its designee pursuant to Article XI in order to ensure that the Corporation remains qualified as a REIT for federal income tax purposes or the purchase or acquisition of shares of Series A Preferred Stock pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding shares of Series A Preferred Stock.

(c) RIGHTS TO DIVIDENDS ON SHARES CALLED FOR REDEMPTION. Immediately prior to any redemption of Series A Preferred Stock, the Corporation shall pay, in cash, any accumulated and unpaid dividends to and including the redemption date, unless a redemption date falls after a Dividend Record Date and prior to the corresponding Dividend Payment Date, in which case each holder of Series A Preferred Stock at the close of business on such Dividend Record Date shall be entitled to the dividend payable on such shares on the corresponding Dividend Payment Date notwithstanding the redemption of such shares before such Dividend Payment Date. Except as provided above, the Corporation will make no payment or allowance for unpaid dividends, whether or not in arrears, on Series A Preferred Stock which is redeemed.

4

(d) PROCEDURES FOR REDEMPTION.

(i) Notice of redemption will be mailed by the Corporation, postage prepaid, not less than 30 nor more than 60 days prior to the redemption date, addressed to the respective holders of record of the Series A Preferred Stock to be redeemed at their respective addresses as they appear on the stock transfer records of the Corporation. No failure to give such notice or any defect thereto or in the mailing thereof shall affect the validity of the proceedings for the redemption of any shares of Series A Preferred Stock except as to the holder to whom notice was defective or not given.

(ii) In addition to any information required by law or by the applicable rules of any exchange upon which Series A Preferred Stock may be listed or admitted to trading, such notice shall state: (A) the redemption date; (B) the redemption price; (C) the number of shares of Series A Preferred Stock to be redeemed; (D) the place or places where the Series A Preferred Stock is to be surrendered for payment of the redemption price; and (E) that dividends on the shares to be redeemed will cease to accrue on such redemption date. If less than all of the Series A Preferred Stock held by any holder is to be redeemed, the notice mailed to such holder shall also specify the number of shares of Series A Preferred Stock held by such holder to be redeemed.

(iii) If notice of redemption of any shares of Series A Preferred Stock has been given and if the funds necessary for such redemption have been set aside by the Corporation in trust for the benefit of the holders of any shares of Series A Preferred Stock so called for redemption, then, from and after the redemption date, dividends will cease to accrue on such shares of Series A Preferred Stock, such shares of Series A Preferred Stock shall no longer be deemed outstanding and all rights of the holders of such shares will terminate, except the right to receive the redemption price. Holders of Series A Preferred Stock to be redeemed shall surrender such Series A Preferred Stock at the place designated in such notice and, upon surrender in accordance with said notice of the certificates for shares of Series A Preferred Stock so redeemed (properly endorsed or assigned for transfer, if the Corporation shall so require and the notice shall so state), such shares of Series A Preferred Stock shall be redeemed by the Corporation at the redemption price plus any accrued and unpaid dividends payable upon such redemption. In case less than all the shares of Series A Preferred Stock represented by any such certificate are redeemed, a new certificate or certificates shall be issued representing the unredeemed shares of Series A Preferred Stock without cost to the holder thereof.

(iv) The deposit of funds with a bank or trust corporation for the purpose of redeeming Series A Preferred Stock shall be irrevocable except that:

(A) the Corporation shall be entitled to receive from such bank or trust corporation the interest or other earnings, if any, earned on any money so deposited in trust, and the holders of any shares redeemed shall have no claim to such interest or other earnings; and

5

(B) any balance of monies so deposited by the Corporation and unclaimed by the holders of the Series A Preferred Stock entitled thereto at the expiration of two years from the applicable redemption dates shall be repaid, together with any interest or other earnings thereon, to the Corporation, and after any such repayment, the holders of the shares entitled to the funds so repaid to the Corporation shall look only to the Corporation for payment without interest or other earnings.

(e) APPLICATION OF ARTICLE XI. The shares of Series A Preferred Stock are subject to the provisions of Article XI of the Charter, including, without limitation, the provision for the redemption of shares transferred to the Trust (as defined in such Article). For this purpose, the market price of the Series A Preferred Stock shall equal $25.00 per share, plus all accrued and unpaid dividends on the shares of Series A Preferred Stock.

(f) STATUS OF REDEEMED SHARES. Any shares of Series A Preferred Stock that shall at any time have been redeemed or otherwise acquired by the Corporation shall, after such redemption or acquisition, have the status of authorized but unissued preferred stock, without designation as to series until such shares are once more classified and designated as part of a particular series by the Board of Directors.

(6) VOTING RIGHTS.

(a) Holders of the Series A Preferred Stock will not have any voting rights, except as set forth below.

(b) Whenever dividends on any shares of Series A Preferred Stock shall be in arrears for six or more quarterly periods (a "Preferred Dividend Default"), the holders of such shares of Series A Preferred Stock (voting separately as a class with all other series of preferred stock ranking on a parity with the Series A Preferred Stock as to dividends or upon liquidation ("Parity Preferred"), upon which like voting rights have been conferred and are exercisable), will be entitled to vote for the election of a total of two additional directors of the Corporation (the "Preferred Stock Directors"), and the number of directors on the Board of Directors shall increase by two, at a special meeting called by the holders of record of at least 20% of the Series A Preferred Stock or the holders of any other series of Parity Preferred so in arrears (unless such request is received less than 90 days before the date fixed for the next annual or special meeting of stockholders) or at the next annual meeting of stockholders, and at each subsequent annual meeting until all dividends accumulated on such shares of Series A Preferred Stock for the past dividend periods and the dividend for the then current dividend period shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment.

(c) If and when all accumulated dividends and the dividend for the then current dividend period on the Series A Preferred Stock shall have been paid in full or set aside for payment in full, the holders of shares of Series A Preferred Stock shall be divested of the voting rights set forth in Section 6(b) hereof (subject to revesting in the event of each and every subsequent Preferred Dividend Default) and, if all

6

accumulated dividends and the dividend for the current dividend period have been paid in full or set aside for payment in full on all other series of Parity Preferred upon which like voting rights have been conferred and are exercisable, the term of office of each Preferred Stock Director so elected shall terminate and the number of directors on the Board of Directors shall decrease by two. Any Preferred Stock Director may be removed at any time with or without cause by the vote of, and shall not be removed otherwise than by the vote of, the holders of record of a majority of the outstanding shares of the Series A Preferred Stock when they have the voting rights set forth in Section 6(b) (voting separately as a class with the Parity Preferred upon which like voting rights have been conferred and are exercisable). So long as a Preferred Dividend Default shall continue, any vacancy in the office of a Preferred Stock Director may be filled by written consent of the Preferred Stock Director remaining in office, or, if none remains in office, by a vote of the holders of record of a majority of the outstanding shares of Series A Preferred Stock when they have the voting rights set forth in Section 6(b) (voting separately as a class with all other series of Parity Preferred upon which like voting rights have been conferred and are exercisable). The Preferred Stock Directors shall each be entitled to one vote per director on any matter.

(d) So long as any shares of Series A Preferred Stock remain outstanding, the Corporation shall not, without the affirmative vote of the holders of at least two thirds of the shares of the Series A Preferred Stock outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting separately as a class, together with all other series of Parity Preferred upon which like voting rights have been conferred and are exercisable), (i) authorize or create, or increase the authorized or issued amount of, any class or series of capital stock ranking prior to the Series A Preferred Stock with respect to payment of dividends or the distribution of assets upon liquidation, dissolution or winding up, or reclassify any authorized capital stock of the Corporation into any such shares, or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any such shares or (ii) amend, alter or repeal the provisions of the Charter, whether by merger, consolidation or otherwise, so as to materially and adversely affect any right, preference, privilege or voting power of the Series A Preferred Stock or the holders thereof; provided, however, that with respect to the occurrence of any event set forth in (ii) above, so long as the Series A Preferred Stock remains outstanding with the terms thereof materially unchanged, the occurrence of any such event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers of the Series A Preferred Stock and; provided, further, that any increase in the amount of the authorized preferred stock, including the Series A Preferred Stock, or the creation or issuance of any additional Series A Preferred Stock or any other series of preferred stock, or any increase in the amount of authorized shares of such series, in each case ranking on a parity with or junior to the Series A Preferred Stock with respect to payment of dividends or the distribution of assets upon liquidation, dissolution or winding up, shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers.

(e) The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, all outstanding shares of Series A Preferred Stock shall have been redeemed or called for redemption upon proper notice and sufficient funds shall have been deposited in trust to effect such redemption.
