ARTICLE II

Effect of the Merger on the Capital Stock of the
Constituent Corporations; Exchange of Certificates

SECTION 2.01. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of FPL Group Common Stock, any shares of Constellation Common Stock or any shares of common stock of Merger Sub:

(a) Cancellation of Certain FPL Group Common Stock. Each share of FPL Group Common Stock that is owned by FPL Group or Constellation shall automatically be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(b) Conversion of FPL Group Common Stock. Each issued and outstanding share of FPL Group Common Stock (other than shares to be cancelled in accordance with Section 2.01(a)) shall be automatically converted, subject to the prior effectiveness of the Stock Split, into the right to receive one fully paid and nonassessable share of Constellation Common Stock (the “Exchange Ratio”). As of the Effective Time, all such shares of FPL Group Common Stock shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate representing any such shares of FPL Group Common Stock shall cease to have any rights with respect thereto, except the right to receive the shares of Constellation Common Stock to be issued or paid in consideration therefor upon the surrender of such certificate in accordance with Section 2.02(b), and the right to receive dividends and other distributions in accordance with Section 2.02(c), in each case, without interest.

(c) Conversion of Merger Sub Common Stock. Each issued and outstanding share of capital stock of Merger Sub shall be automatically converted into and become one fully paid and nonassessable share of common stock, par value $.01 per share, of the Surviving Corporation.

SECTION 2.02. Exchange of Certificates. (a) Exchange Agent. As of the Effective Time, Constellation shall enter into an agreement with such bank or trust company as may be mutually agreed to by FPL Group and Constellation (the “Exchange

Agent”), which agreement shall provide that Constellation shall deposit with the Exchange Agent as of the Effective Time, in trust for the benefit of the holders of Certificates, certificates representing the shares of Constellation Common Stock (such shares of Constellation Common Stock being hereinafter referred to as the “Merger Consideration”, and together with any dividends or other distributions with respect thereto with a record date after the Effective Time, collectively being hereinafter referred to as the “Exchange Fund”) issuable pursuant to Section 2.01(b) in exchange for the shares of FPL Group Common Stock that were outstanding immediately prior to the Effective Time.

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates that immediately prior to the Effective Time represented outstanding shares of FPL Group Common Stock (the “Certificates”) whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.01(b), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as FPL Group and Constellation may reasonably specify) and (ii) instructions for use in surrendering the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Constellation Common Stock that such holder has the right to receive pursuant to the provisions of this Article II and certain dividends or other distributions in accordance with Section 2.02(c), and the Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of FPL Group Common Stock that is not registered in the transfer records of FPL Group, a certificate representing the proper number of shares of Constellation Common Stock may be issued to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such issuance shall pay any transfer or other Taxes required by reason of the issuance of shares of Constellation Common Stock to a person other than the registered holder of such Certificate or establish to the satisfaction of Constellation that such Tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration which the holder thereof has the right to receive in respect of such Certificate pursuant to the provisions of this Article II and certain dividends or other distributions in accordance with Section 2.02(c). No interest shall be paid or will accrue on the Merger Consideration or any cash payable to holders of Certificates pursuant to the provisions of this Article II.

(c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Constellation Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate

with respect to the shares of Constellation Common Stock issuable hereunder in respect thereof, and all such dividends and other distributions shall be paid by Constellation to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Certificate in accordance with this Article II. Subject to the effect of applicable escheat or similar Laws, following surrender of any such Certificate to the Exchange Agent for cancellation there shall be paid to the holder of the certificate representing whole shares of Constellation Common Stock issued in exchange therefor, without interest, (i) promptly after the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Constellation Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of Constellation Common Stock.

(d) No Further Ownership Rights in FPL Group Common Stock. All shares of Constellation Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms of this Article II (and any dividends or other distributions, in each case, pursuant to this Article II) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of FPL Group Common Stock theretofore represented by such Certificates, subject, however, to FPL Group’s obligation to pay any dividends or make any other distributions expressly permitted by the terms of this Agreement with a record date prior to the Effective Time that may have been declared or made by FPL Group on such shares of FPL Group Common Stock that remain unpaid at the Effective Time, and there shall be no further registration of transfers on the stock transfer books of FPL Group of the shares of FPL Group Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to Constellation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II, except as otherwise provided by Law.

(e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of the Certificates for 12 months after the Effective Time shall be delivered to Constellation, upon demand, and any holders of the Certificates who have not theretofore complied with this Article II shall thereafter look only to Constellation for payment of their claim for Merger Consideration, any dividends or other distributions with respect to Constellation Common Stock.

(f) No Liability. None of Constellation, the Surviving Corporation or the Exchange Agent or any of their respective directors, officers, employees and agents shall be liable to any person in respect of any shares of Constellation Common Stock, any dividends or other distributions with respect thereto, in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate shall not have been surrendered prior to five years after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration or any dividends or other distributions payable to the holder of such Certificate would otherwise escheat to or become the property of any Governmental Authority), any such

Merger Consideration, dividends or other distributions in respect of such Certificate shall, to the extent permitted by applicable Law, become the property of Constellation, free and clear of all claims or interest of any person previously entitled thereto.

(g) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Constellation, on a daily basis. Any interest and other income resulting from such investments shall be paid to Constellation.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Constellation or the Exchange Agent, the posting by such person of a bond in such reasonable amount as Constellation or the Exchange Agent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration and, if applicable, any unpaid dividends and distributions on shares of Constellation Common Stock deliverable in respect thereof, in each case pursuant to this Agreement.

(i) Withholding Taxes. Each of the parties and the Exchange Agent will be entitled to deduct and withhold from amounts otherwise payable under this Article II any amounts that it is required to deduct and withhold with respect to such payments under any provision of Tax Law. Any amounts so deducted and withheld will be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made.

ARTICLE III

Each of the FPL Group Nuclear Facilities maintains, and is in material compliance with, emergency plans designed to respond to an unplanned Release therefrom of radioactive materials and each such plan conforms with the requirements of applicable Law in all material respects. The plans for the decommissioning of each of the FPL Group Nuclear Facilities and for the storage of spent nuclear fuel conform with the requirements of applicable Law in all material respects and, solely with respect to the portion of the FPL Group Nuclear Facilities owned, directly of indirectly, by FPL Group, the funding of decommissioning and storage of spent nuclear fuel is consistent with applicable Law.

individually or in the aggregate, have not had and would not reasonably be expected to have a material adverse effect on FPL Group. FPL Group and its subsidiaries and each of the FPL Group Joint Ventures maintain liability insurance to the full extent required by Law for operating the FPL Group Nuclear Facilities, and such insurance regarding such facilities remains in full force and effect in all material respects.

(p) Insurance. Except for failures to maintain insurance or self-insurance that, individually or in the aggregate, have not had and would not reasonably be expected to have a material adverse effect on FPL Group, from January 1, 2004, through the date of this Agreement, each of FPL Group and its subsidiaries has been continuously insured with financially responsible insurers or has self-insured, in each case in such amounts and with respect to such risks and losses as are customary for companies in the United States conducting the business conducted by FPL Group and its subsidiaries during such time period. Neither FPL Group nor any of its subsidiaries has received any notice of cancellation or termination with respect to any insurance policy of FPL Group or any of its subsidiaries, except with respect to any cancellation or termination that, individually or in the aggregate, has not had and would not reasonably be expected to have a material adverse effect on FPL Group.

As of the date of this Agreement, (i) FPL Group’s VaR is in compliance with the FPL Group Approved VaR Limit, and FPL Group and its subsidiaries are operating in compliance with the FPL Group Trading Guidelines in all material respects and (ii) the aggregate net positions in the trading and managed hedge portfolio (i.e., xxxx-to-market positions excluding non-qualifying xxxxxx) of FPL Group and its subsidiaries would not reasonably be expected to result in a material loss to FPL Group and its subsidiaries, taken as a whole, based on market prices in existence as of the date of this Agreement. From September 30, 2005, to the date of this Agreement, neither FPL Group nor any of its subsidiaries has, in accordance with its xxxx-to-market accounting policies, experienced an aggregate net trading loss in FPL Group’s trading and managed hedge portfolio (i.e., xxxx-to-market positions excluding non-qualifying xxxxxx) that would be material to FPL Group and its subsidiaries taken as a whole. For purposes of this Section 3.01(q) and Section 4.02(h), “VaR” shall mean the value-at-risk of the xxxx-to-market trading and managed hedge portfolio (i.e., xxxx-to-market positions excluding non-qualifying xxxxxx) of FPL Group and its marketing and trading subsidiaries based on a two standard deviation move in prices and a one-day holding period.

(u) Joint Venture Representations. Each representation or warranty made by FPL Group in this Section 3.02 relating to a FPL Group Joint Venture that is neither operated nor managed by FPL Group or a FPL Group subsidiary shall be deemed made only to the knowledge of FPL Group.

(v) Opinion of Financial Advisor. FPL Group has received the opinions of Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated and Xxxxxx Brothers Inc., each dated the date of this Agreement to the effect that, as of the date of this Agreement and based upon and subject to the matters set forth therein, the Exchange Ratio, assuming the prior effectiveness of the Stock Split, is fair from a financial point of view to the shareholders of FPL Group.

(x) Rights Agreement. FPL Group has taken all actions necessary so that the execution of this Agreement and the consummation of the Merger and other transactions contemplated hereby do not and will not result in the grant of any

increased rights to any person under the FPL Group Rights Agreement or enable, require or cause the FPL Group Rights to be exercised, distributed or triggered.

SECTION 5.04. Access to Information; Confidentiality; Effect of Review. (a) Access. Subject to the Confidentiality Agreement, to the extent permitted by applicable Law each of FPL Group and Constellation shall, and shall cause each of its respective subsidiaries to, afford to the other party, and to the officers, employees, accountants, counsel, financial advisors and other representatives of such other party, pursuant to integration policies to be adopted by the integration leaders designated by each of Constellation and FPL Group, reasonable access during normal business hours during the period prior to the Effective Time to all their respective properties, books, contracts, commitments, personnel and records and, during such period, to the extent permitted by applicable Law, each of FPL Group and Constellation shall, and shall cause each of its respective subsidiaries to, (i) confer on a regular and reasonable basis with one or more representatives of the other party to discuss material operational and regulatory matters and the general status of its ongoing operations for purposes related to the completion of the transactions contemplated by this Agreement (including, without limitation, a party’s assessment of the proper accounting for such transactions, any public disclosures that a party is required to make regarding such transactions and reasonable access to management and systems needed for integration planning) or the fulfillment of its obligations under this Agreement, (ii) advise the other party of any change or event that has had or would reasonably be expected to have a material adverse effect on such party and (iii) furnish promptly all other information concerning its business, properties and personnel, in each case as such other party may reasonably request in connection with activities relating to the completion of the transactions contemplated by this Agreement or the fulfillment of its obligations under this Agreement; provided, however, that (A) no actions shall be taken pursuant to this Section 5.04(a) that (x) would result in a waiver of the attorney/client privilege or (y) could reasonably be expected to result in violation of applicable Law, including antitrust Laws, and (B) each of the parties shall, without being deemed to have violated this Section 5.04, be permitted to continue to limit the other party’s access to its wholesale competitive supply business, retail competitive supply business and wind business to aggregated information per business line that takes due account of competitive considerations.

Notwithstanding the foregoing, if a party requests access to proprietary information of the other party, the disclosure of which could reasonably be expected to materially impair the competitive position or operations of the other party if the Closing were not to occur (giving effect to the requesting party’s obligations under the Confidentiality Agreement), such information shall only be disclosed to the extent reasonably agreed upon by the chief financial officers (or their designees) of FPL Group and Constellation.

(b) Further Actions. Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things reasonably necessary or advisable to consummate and make effective, in the most expeditious manner reasonably practicable, the Merger and the other transactions contemplated by this Agreement, including (i) the defending of any lawsuits or other legal proceedings, whether judicial

or administrative, challenging this Agreement or the consummation of the transactions contemplated by this Agreement, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Authority vacated or reversed, and (ii) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by this Agreement.

Notwithstanding the foregoing, as used in this Section 5.05, “reasonable best efforts” shall not include nor require any party to (i) sell, or agree to sell, hold or agree to hold separate, or otherwise dispose or agree to dispose of any asset, in each case if such sale, separation or disposition or agreement with respect thereto would, individually or in the aggregate, reasonably be expected to have a material adverse effect on such party or on Constellation and its prospective subsidiaries, taken as a whole, or (ii) conduct or agree to conduct its business in any particular manner if such conduct or agreement with respect thereto would individually or in the aggregate, reasonably be expected to have a material adverse effect on such party or on Constellation and its prospective subsidiaries, taken as a whole.

(c) State Anti-Takeover Statutes. Without limiting the generality of Section 5.05(b), FPL Group and Constellation shall (i) take all action necessary to ensure that no state anti-takeover statute or similar statute or regulation is or becomes applicable to the Merger, this Agreement or any of the other transactions contemplated by this Agreement and (ii) if any state anti-takeover statute or similar statute or regulation becomes applicable to the Merger, this Agreement or any other transaction contemplated by this Agreement, take all action necessary to ensure that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as reasonably practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Merger and the other transactions contemplated by this Agreement.

(ii) provide that each share of FPL Group Restricted Stock shall be converted, subject to the prior effectiveness of the Stock Split, into one share of Constellation Restricted Stock (each such share, as so adjusted, the “FPL Group Adjusted Restricted Stock”), on the same terms and conditions as were applicable to such share of FPL Group Restricted Stock, including vesting;

(iii) adjust the terms of all outstanding FPL Group Other Equity-Based Awards, whether vested or unvested, as necessary to provide that each such FPL Group Other Equity-Based Award outstanding immediately prior to the Effective Time shall be amended and converted, subject to the prior effectiveness of the Stock Split, into an equity or equity-based award in respect of a number of shares of Constellation Common Stock (each, a “FPL Group Adjusted Other Equity-Based Award”) equal to the number of shares of FPL Group Common Stock subject to such FPL Group Other Equity-Based Award immediately before the Effective Time, on the same terms and conditions as were applicable to such FPL Group Other Equity-Based Award, including vesting, and, if such FPL Group Other Equity-Based Award is subject to an exercise or subscription price, the exercise or subscription price per share of such FPL Group Adjusted Other Equity-Based Award shall be equal to the exercise or subscription price per share of such FPL Group Other Equity-Based Award immediately before the Effective Time (rounded up to the nearest whole cent);

(iv) use reasonable best efforts to ensure (A) that the conversion pursuant to Section 2.01(b) of any FPL Group Common Stock held by any director or officer of FPL Group who is subject to Section 16(a) of the Exchange Act, (B) the conversion pursuant to this Section 5.06(a) of any FPL Group Employee Stock Options held by any such director or officer of FPL Group into FPL Group Adjusted Options and (C) the conversion pursuant to this Section 5.06(a) of any FPL Group Restricted Stock or FPL Group Other Equity-Based Awards held by any such director or officer of FPL Group into FPL Group Adjusted Restricted Stock or FPL Group Adjusted Other Equity-Based Awards, in each case will be eligible for exemption under Rule 16b-3(e); and

(v) make such other changes to the FPL Group Stock Plans as FPL Group and Constellation may agree are appropriate to give effect to the Merger.

(b) As soon as practicable after the Effective Time, Constellation shall deliver to the holders of FPL Group Adjusted Options, FPL Group Adjusted Restricted Stock and FPL Group Adjusted Other Equity-Based Awards (collectively, the “FPL Group Adjusted Awards”) appropriate notices setting forth such holders’ rights pursuant to the FPL Group Stock Plans and the agreements evidencing the grants of such FPL Group Adjusted Awards, and stating that such FPL Group Adjusted Awards and the related agreements shall be assumed by Constellation and shall continue in effect on the same terms and conditions, including with respect to vesting (subject to the adjustments required by this Section 5.06 after giving effect to the Merger).

(c) Except as otherwise contemplated by this Agreement and except to the extent required under the respective terms of the FPL Group Employee Stock Options, FPL Group Restricted Stock and FPL Group Other Equity-Based Awards, all restrictions or limitations on transfer and vesting with respect to such FPL Group Employee Stock Options, FPL Group Restricted Stock and FPL Group Other Equity-Based Awards, to the extent that such restrictions or limitations shall not have already lapsed, shall remain in full force and effect with respect to the applicable FPL Group Adjusted Awards after giving effect to the Merger and the assumption of such awards by Constellation as set forth above.

(d) Notwithstanding any provision of Section 5.06(a), FPL Group Employee Stock Options, FPL Group Restricted Stock and FPL Group Other Equity-Based Awards granted after the date of this Agreement, as permitted by Section 4.02(d), (i) shall not vest on the FPL Group Stockholder Approval or otherwise in connection with the occurrence of the transactions contemplated hereby, (ii) shall not be cashed out or terminated in connection with the occurrence of the transactions contemplated hereby, (iii) shall not entitle the holders thereof to any future grants of stock options or other awards (including any “replacement option” grants), (iv) shall be converted at the Effective Time into FPL Group Adjusted Awards and (v) shall otherwise remain in full force and effect and be eligible to become vested in accordance with their terms following the Effective Time.

(e) At the Effective Time, by virtue of the Merger, the FPL Group Stock Plans shall be deemed assumed by Constellation, with the result that all obligations of FPL Group under the FPL Group Stock Plans, including with respect to awards outstanding at the Effective Time under the FPL Group Stock Plans, shall be obligations of Constellation following the Effective Time. Prior to the Effective Time, Constellation shall take all necessary actions for the assumption of the FPL Group Stock Plans by Constellation, including the reservation, issuance and listing of Constellation Common Stock in a number at least equal to the number of shares of Constellation Common Stock that will be subject to FPL Group Adjusted Awards. As promptly as practicable following the Effective Time, Constellation shall use reasonable best efforts to prepare and file with the SEC a registration statement on Form S-8 (or another appropriate form) registering a number of shares of Constellation Common Stock determined in accordance with the preceding sentence.

(a) Following the Effective Time, Constellation will (subject to Sections 5.06, 5.07, this Section 5.08 and Section 5.09), and will cause its subsidiaries to (i) honor all obligations under any contracts, agreements, collective bargaining agreements, plans and commitments (as such may be amended in accordance with this Agreement) of FPL Group and its subsidiaries that exist on the date of this Agreement (or as established or amended in accordance with or permitted by this Agreement) that apply to any current or former employee, or current or former director, of FPL Group or any of its subsidiaries and (ii) continue to honor all obligations under any contracts, agreements, collective bargaining agreements, plans and commitments (as such may be amended in accordance with this Agreement) of Constellation and its subsidiaries that exist on the date of this Agreement (or as established or amended in accordance with or permitted by this Agreement) that apply to any current or former employee, or current or former director, of Constellation or any of its subsidiaries, including the obligation to issue “replacement options” as described in Section 4.01(i) of the Constellation Disclosure Letter; provided, however, that the undertakings set forth in this Section 5.08(a) are not intended to prevent Constellation and its subsidiaries from enforcing such contracts, agreements, collective bargaining agreements, plans and commitments (as such may be amended in accordance with this Agreement) in accordance with their respective terms, including any reserved right to amend, modify, suspend, revoke or terminate any such contract, agreement, collective bargaining agreement or commitment.

(b) At the Effective Time, it shall be the intent of Constellation, that (subject to obligations under applicable Law and applicable collective bargaining agreements) (i) any reductions in the employee work force of Constellation and its subsidiaries shall be made on a fair and equitable basis (as determined by Constellation and its subsidiaries), in light of the circumstances and the objectives to be achieved,

If such insurance coverage cannot be maintained, Constellation shall, or shall cause the Surviving Corporation to, maintain the most advantageous policies of directors and officers insurance otherwise obtainable.

(c) The provisions of Section 5.09(a) (i) are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her representatives and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise.

STOCKHOLDERS

Section 1. - Place of Meetings.

Meetings of stockholders of the Corporation shall be held at such places, either within or without the State of Maryland or the State of Florida, as may be fixed from time to time by the Board and stated in the notice of meeting or in a duly executed waiver of notice thereof.

Section 2. - Annual Meetings.

The Annual Meeting of the stockholders for the election of Directors and for the transaction of general business shall be held on any date during the period of May 1 through May 31 as determined from year to year by the Board. The time and location of the meeting shall be determined by the Board. Failure to hold an Annual Meeting does not invalidate the Corporation’s existence or affect any otherwise valid corporate acts.

The Chief Executive Officer of the Corporation shall prepare, or cause to be prepared, an annual report containing a full and correct statement of the affairs of the Corporation, including a balance sheet and a financial statement of operations for the preceding fiscal year, which shall be submitted to the stockholders at or prior to the Annual Meeting.

Section 3. - Special Meetings.

Special meetings of the stockholders may be held in Baltimore, Maryland, Juno Beach, Florida or in any county within the State of Maryland or the State of Florida or in which the Corporation provides service or owns property upon call by the Chairman of the Board, the Chief Executive Officer or a majority of the Board whenever they deem expedient, or by the Secretary upon the written request of the holders of shares entitled to not less than a majority of all the votes entitled to be cast at such meeting. Such request of the stockholders shall state the purpose or purposes of the meeting and the matters proposed to be acted on and shall be delivered to the Secretary, who shall inform such stockholders of the reasonably estimated cost of preparing and mailing such notice of the meeting, and upon payment to the Corporation of such costs the Secretary shall give notice stating the purpose or purposes of the meeting to all stockholders entitled to vote at such meeting. The business at all special meetings shall be confined to that specifically named in the notice thereof.

Section 4. - Notice and Waiver; Organization of Meeting.

When stockholders are required or permitted to take any action at a meeting whether special or annual, written, printed or electronic notice of every meeting shall be given to each stockholder entitled to vote at the meeting and each other stockholder entitled to notice of the meeting. The notice shall state the place, day, and hour of such meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called. The notice of any meeting shall be given, personally, by mail or electronically, not less than 10 or more than 90 days before the date of the meeting.

Any notice given by the Corporation to a stockholder is effective if given by a single notice, in writing or by electronic transmission, to all stockholders who share an address if the Corporation gives notice, in writing or by electronic transmission, to the stockholder of its intent to give a single notice and the stockholder consents to receiving a single notice or fails to object in writing within 60 days after the Corporation gives notice to the stockholder of its intent to give a single notice. A stockholder may revoke consent given, whether affirmative or implied, by written notice to the Corporation. The notice shall state the time of the meeting, the place of the meeting, if any, and the means of remote communication, if any, by which stockholders and proxy holders may be deemed to be present in person and may vote at the meeting and, if the meeting is a special meeting or notice of the purpose is required by statute, the purpose of the meeting. Notice is given to a stockholder when it is personally delivered to the stockholder, left at the stockholder’s residence or usual place of business, mailed to the stockholder at the stockholder’s address as it appears on the records of the Corporation or transmitted to the stockholder by an electronic transmission to any address or number of the stockholder at which the stockholder receives electronic transmissions. If the Corporation has received a request from a stockholder that notice not be sent by electronic transmission, the Corporation may not provide notice to the stockholder by electronic transmission. Notice given by electronic transmission shall be considered ineffective if the Corporation is unable to deliver two consecutive notices and the inability to deliver the notices becomes known to the Secretary, an Assistant Secretary, the transfer agent or other person responsible for giving the notice. The inadvertent failure to deliver any notice by electronic transmission does not invalidate any meeting or other action. An affidavit of the Secretary, the transfer agent or other agent of the Corporation that notice has been given by a form of electronic transmission, in the absence of actual fraud, shall be prima facie evidence of the facts stated in the affidavit.

The business at all special meetings shall be confined to that specifically named in the notice thereof.

When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken unless the adjournment is to a date more than 120 days after the original record date, or, if after the

adjournment, a new record date is fixed for the adjourned meeting, in which circumstances a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting.

Notice of any meeting of stockholders may be waived before or after the meeting in writing or by electronic transmission by any stockholder entitled to notice of such meeting. Attendance at a meeting by any stockholder, in person or by proxy, shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

All meetings of the stockholders shall be called to order by the Chairman of the Board, or in his or her absence by the Chief Executive Officer, the President or a Vice President; or in the case of the absence of such Officers, then by any stockholder. The party calling the meeting to order shall be Chairman of the meeting. The Secretary of the Corporation, if present, shall act as secretary of the meeting, unless some other person shall be elected by the stockholders at the meeting to act as secretary. An accurate record of the meeting shall be kept by the secretary thereof, and placed in the record books of the Corporation.

(b) For nominations or other business to be brought properly before an Annual Meeting by a stockholder, the stockholder must have given timely notice thereof in proper written form to the Secretary of the Corporation. To be timely, a stockholder’s notice must be delivered to or mailed and received at the principal office of the Corporation not less than 90 days nor more than 120 days prior to the anniversary of the date on which notice of the prior year’s Annual Meeting was given to stockholders in accordance with Section 4 of this Article II. Notices sent by facsimile or electronically will not be accepted by the Secretary of the Corporation. To be in proper written form, a stockholder’s notice to the Secretary shall set forth in writing as to each matter the stockholder proposes to bring before the Annual Meeting:

(i) as to each person whom the stockholder proposes to nominate for election or re-election as a Director, all information relating to such person that is required to be disclosed in solicitations of proxies for election of Directors, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934 (the “Exchange Act”) or any applicable successor provisions thereto, including such person’s written consent to being named in the proxy statement as a nominee and to serving as a Director if elected; and as to the stockholder giving the notice, the name and address, as they appear on the Corporation’s books, of the stockholder proposing such nomination and the class and number of shares of stock of the Corporation which are beneficially owned by the stockholder.

(ii) as to any other business that the stockholder proposes to bring before the meeting:

(A) a brief description of the business desired to be brought before the Annual Meeting and the reasons for conducting such business at the Annual Meeting;

(B) the name and address, as they appear on the Corporation’s books, of the stockholder proposing such business;

(D) any material interest of the stockholder in such business.

(c) Notwithstanding anything in these By-Laws to the contrary, no business shall be conducted at an Annual Meeting except in accordance with the procedures set forth in this Section 5 of Article II. The Chairman of an Annual Meeting shall, if the facts warrant, determine and declare at the Annual Meeting that business was not properly brought before the Annual Meeting in accordance with the provisions of this Section 5 of Article II and, if the Chairman should so determine, he or she shall so declare at the Annual Meeting and any such business not properly brought before the Annual Meeting shall not be transacted.

(d) Notwithstanding the foregoing provisions of this Section, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section. Nothing in this Section shall be deemed to affect any rights of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act.

Section 6. - Quorum.

At any meeting of the stockholders the presence in person or by proxy of stockholders entitled to cast a majority of the votes thereat shall constitute a quorum for the transaction of business.

When a quorum is once present to organize a meeting, it is not broken by the subsequent withdrawal of any stockholders.

The stockholders present, although less than a quorum, may adjourn the meeting to another time or place; provided that notice of such adjourned meeting is given in accordance with the provisions of Section 4 of this Article II.

Section 7. - Voting; Proxies.

At all meetings of the stockholders each stockholder shall be entitled to one vote for each share of Common Stock standing in his or her name and, when the Preferred Stock is entitled to vote, such number of votes as shall be provided in the Charter of the Corporation for each share of Preferred Stock standing in his or her name, and the votes shall be cast by stockholders in person or by lawful proxy. However, no proxy shall be voted 11 months after the date thereof, unless the proxy provides for a longer period.

Section 8. - Control Shares.

Notwithstanding any other provision of the Charter of the Corporation or these By-Laws, Title 3, Subtitle 7 of the Maryland General Corporation Law (or any successor statute) shall not apply to any acquisition by any person of shares of stock of the Corporation. This section may be repealed, in whole or in part, at any time, whether before or after an acquisition of control shares and, upon such repeal, such statute may, to the extent provided by any successor by-law, apply to any prior or subsequent control share acquisition.

Section 9. - Method of Voting.

All elections and all other questions shall be decided by a majority of the votes cast, at a meeting at which a quorum is present, except as expressly provided otherwise by the general laws of the State of Maryland or the Charter and except that Directors shall be elected by a plurality of the votes cast.

Section 10. - Ownership of its Own Stock.

Shares of capital stock of the Corporation held by either (i) the Corporation or (ii) another corporation, if a majority of the shares entitled to vote in the election of Directors of such other corporation is held, directly or indirectly, by the Corporation (a “Controlled Corporation”), shall neither be entitled to vote nor be counted for quorum purposes. Nothing in this Section 10 shall be construed as limiting the right of the Corporation or any Controlled Corporation to vote stock of the Corporation held by it in a fiduciary capacity.

Section 11. - Inspectors.

The Board, in advance of any meeting, may, but need not, appoint one or more individual inspectors or one or more entities that designate individuals as inspectors to act at the meeting or any adjournment thereof. If an inspector or inspectors are not appointed, the person presiding at the meeting may, but need not, appoint one or more inspectors. In case any person who may be appointed as an inspector fails to appear or act, the vacancy may be filled by appointment made by the Board in advance of the meeting or at the meeting by the chairman of the meeting. The inspectors, if any, shall determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots or consents, determine the result, and do such acts as are proper to conduct the election or vote with fairness to all stockholders. Each such report shall be in writing and signed by him or her or by a majority of them if there is more than one inspector acting at such meeting. If there is more than one inspector, the report of a majority shall be the report of the inspectors. The report of the inspector or inspectors on the number of shares represented at the meeting and the results of the voting shall be prima facie evidence thereof.

Section 12. - Record Date for Stockholders; Closing of Transfer Books.

The Board may fix, in advance, a date as the record for the determination of the stockholders entitled to notice of, or to vote at, any meeting of stockholders, or entitled to receive payment of any dividend, or entitled to the allotment of any rights, or for any other proper purpose. Such date in any case shall not be more than 90 days (and in the case of a meeting of stockholders not less than 10 days) prior to the date on which the particular action requiring such determination of stockholders is to be taken (other than in the case of an adjournment). Only stockholders of record on such date shall be entitled to notice of or to vote at such meeting or to receive such dividends or rights, as the case may be. In lieu of fixing a record date the Board may close the stock transfer books of the Corporation for a period not exceeding 20 nor less than 10 days preceding the date of any meeting of stockholders or not exceeding 20 days preceding any other of the above mentioned events.
