The annual meeting of the stockholders of the Corporation shall be held on such date in each year and at such time and place as may be determined by the Board of Directors, for the purpose of electing Directors and for the transaction of such other proper business as may come before the meeting. Should the stockholders fail to elect Directors on the day designated for their annual meeting or before an adjournment thereof, the Board of Directors shall call a special meeting of the stockholders as soon thereafter as practical.

Special meetings of the stockholders of the Corporation may be called by the Board of Directors or by the Chairman to be held on such date as the Board of Directors or the Chairman shall determine.

2. Advance notice for business.

A. Proposed business. At an annual meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual meeting, business must be (i) specified in the notice of the meeting (or any supplement thereto) given by or at the direction of the Board of Directors, (ii) otherwise brought before the meeting by or at the direction of the Board of Directors or (iii) brought before the meeting by a stockholder in accordance with the procedure set forth below. For business (other than nominations) to be properly brought before an annual meeting by a stockholder, the stockholder must be a stockholder of record on the date of giving written notice and on the record date for the determination of stockholders entitled to vote at such annual meeting and provided timely notice in accordance with this Section 2.

B. Timely notice. In addition to any other applicable requirements, for business proposed by a stockholder, the stockholder must have given written notice thereof, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the Corporation, not later than 90 days nor earlier than the 120th day prior to the anniversary of the previous year’s annual meeting; provided, however, that in the event that no annual meeting was held in the previous year or the annual meeting is scheduled to be held on a date more than thirty (30) days prior to or delayed by more than sixty (60) days after such anniversary date, notice by the stockholder in order to be timely must be so received not later than the later of the close of business ninety (90) days prior to the annual meeting or the tenth (10th) day following the day on which such notice of the date of the annual meeting was mailed or such public disclosure of the date of the annual meeting was made, which may include any public filing by the Corporation with the Securities and Exchange Commission of the date of the annual meeting. Notwithstanding the above, for purposes of determining whether a stockholder’s notice shall have been received in a timely manner for the annual meeting of stockholders in 2008, to be timely, a stockholder’s notice must have been received not later than the close of business on January 5, 2008. The public announcement of an adjournment of an annual meeting shall not commence a new time period for the giving of a stockholder’s notice as described in this Section 2.

C. Form of notice. Any such notice with respect to any business (other than nominations) shall set forth as to each matter the stockholder proposes to bring before the annual meeting (a) a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at the meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend either the Certificate of Incorporation or By-laws of the Corporation, the language of the proposed amendment, and the reasons for conducting such business at the annual meeting; (b) the name and address of the stockholder proposing such business and the name and record address of the beneficial owner, if any, on whose behalf the proposal is made; (c) the class or series and number of shares of capital stock of the Corporation that are owned beneficially and of record by such stockholder and by the beneficial owner, if any, on whose behalf the proposal is made; (d) a description of all arrangements or understandings between such stockholder and any other person or persons (including their names) in connection with the proposal of such business by such stockholder and any material interest of any stockholder in such business; and (e) a representation that the stockholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business. No business shall be conducted at an annual meeting except in accordance with this paragraph, and the chairman of any annual meeting of stockholders may refuse to permit any business to be brought before such annual meeting without compliance with the foregoing procedures.

D. Other requirements. In addition to the provisions of this Section 2, a stockholder shall also comply with all applicable requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations thereunder with respect to the matters set forth herein.

3. Place of meetings. The Board of Directors may designate a place, either within or without the state of Delaware, as the place of meeting for the annual meeting or for a special meeting called by the Board of Directors, provided that the Board may in its sole discretion determine that the meeting shall not be held at any place, but may instead be held solely by means of remote communication. If authorized by the Board of Directors in its sole discretion, and subject to such guidelines and procedures as the Board of Directors may adopt, stockholders and proxy holders not physically present at a meeting of stockholders may, by means of remote communication (i) participate in a meeting of stockholders; and (ii) be deemed present in person and vote at a meeting of stockholders, whether such meeting is to be held at a designated place or solely by means of remote communication, provided that (A) the Corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at a meeting by means of remote communication is a stockholder or proxy holder, (B) the Corporation shall implement reasonable measures to provide such stockholders and proxy holders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (C) if any stockholder or proxy holder votes or takes other action at the meeting by means of remote communication, a record of such votes or other action shall be maintained by the Corporation.

4. Notice of meetings. The Corporation’s Secretary shall deliver to each stockholder of record entitled to vote at a meeting, not less than ten nor more than sixty days before the meeting date, notice, stating the place, day, and hour of the meeting, the means of remote communications, if any, by which stockholders and proxy holders may be deemed present in person and vote at such meeting, and, in the case of a special meeting, the purpose or purposes of the meeting.

5. Record dates.

A. Meetings. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall not be more than 60 nor less than 10 days before the date of such meeting. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the business day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for the adjourned meeting.

B. Dividends. In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

6. List of stockholders. Prior to every meeting of stockholders, the Secretary shall prepare a complete list of stockholders entitled to vote at the meeting, arranged in alphabetical order, with the address of each and the number of voting shares held by each. Any stockholder may examine this list at the Corporation’s principal office during the ten days immediately preceding the meeting for any purpose germane to the meeting. This list shall be produced and kept at the place of the meeting during the whole time thereof, and subject to inspection by any stockholder present.

7. Business. The Chairman shall preside at the stockholders’ meeting, confine the business to the objects stated in the call, and, when in order, approve all minutes prepared by the Secretary. The Chairman may specify a manual or other authority of parliamentary procedure as a guide for conducting the meeting; provided, that once a manual is selected, that manual shall control for all meetings. The Chairman may rely upon the interpretations of corporate counsel in matters of parliamentary law.

8. Quorum. The holders of a majority of the shares of the stock issued and outstanding and entitled to vote thereat, present or represented by proxy, shall be requisite for and shall constitute a quorum at all stockholders’ meetings for the transaction of business, except as otherwise provided by statute, by the Certificate of Incorporation, or by these By-laws. If less than a majority of the outstanding shares are represented at a meeting, however, a majority of the shares so represented may adjourn the meeting, from time to time without notice other than by announcement at the meeting, until a quorum shall be present or represented. At such adjourned meeting, where a quorum shall be present or represented, all business may be transacted which might have been transacted at the meeting originally called.

9. Vote. Subject to the rights of the holders of one or more series of preferred stock of the corporation (“Preferred Stock”), voting separately by class or series, to elect directors pursuant to the terms of one or more series of Preferred Stock, the election of directors shall be determined by a plurality of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon. All other matters shall be determined by the vote of the holders of a majority of the stock having voting power present or represented by proxy, unless the matter is one which, by express provisions of the Delaware Statutes, the Certificate of Incorporation, these By-laws or applicable stock exchange rules, a different vote is required, in which case such express provision shall govern and control the decision of the matter.

10. Proxy. At all stockholders’ meetings, each stockholder having the right to vote shall be entitled to vote in person, by remote communication, if applicable, or by proxy granted in accordance with Delaware law, appointed by a written instrument subscribed by the stockholder and bearing a date not more than three (3) years prior to the meeting, unless the instrument specifically provides for a longer period.

11. Written consents. Unless otherwise restricted by the Certificate of Incorporation or these By-laws, any action required to be taken at any annual or special meeting of stockholders, or any action which may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted, and shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meeting of stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested.

ARTICLE IV

NOTICE

1. Method.

A. A Notice to Directors. Whenever under applicable law, the Certificate of Incorporation or these By-laws notice is required to be given to any director, such notice shall be given either (i) in writing and sent by hand delivery, through the United States mail, or by a nationally recognized overnight delivery service for next day delivery, (ii) by means of facsimile telecommunication or other form of electronic transmission, or (iii) by oral notice given personally or by telephone. A notice to a director will be deemed given as follows: (i) if given by hand delivery, orally, or by telephone, when actually received by the director, (ii) if sent through the United States mail, when deposited in the United States mail, with postage and fees thereon prepaid, addressed to the director at the director’s address appearing on the records of the Corporation, (iii) if sent for next day delivery by a nationally recognized overnight delivery service, when deposited with such service, with fees thereon prepaid, addressed to the director at the director’s address appearing on the records of the Corporation, (iv) if sent by facsimile telecommunication, when sent to the facsimile transmission number for such director appearing on the records of the Corporation, (v) if sent by electronic mail, when sent to the electronic mail address for such director appearing on the records of the Corporation, or (vi) if sent by any other form of electronic transmission, when sent to the address, location or number (as applicable) for such director appearing on the records of the Corporation.

B. Notice to Stockholders. Whenever under applicable law, the Certificate of Incorporation or these By-laws notice is required to be given to any stockholder, such notice shall be given either (i) in writing and sent by hand delivery, through the United States mail, or by a nationally recognized overnight delivery service for next day delivery, (ii) by means of a form of electronic transmission consented to by the stockholder, to the extent permitted by, and subject to the conditions set forth in Section 232 of the Delaware General Corporation Law (“DGCL”). A notice to a stockholder shall be deemed given as follows: (i) if given by hand delivery, when actually received by the stockholder, (ii) if sent through the United States mail, when deposited in the United States mail, with postage and fees thereon prepaid, addressed to the stockholder at the stockholder’s address appearing on the stock ledger of the Corporation, (iii) if sent for next day delivery by a nationally recognized overnight delivery service, when deposited with such service, with fees thereon prepaid, addressed to the stockholder at the stockholder’s address appearing on the stock ledger of the Corporation, and (iv) if given by a form of electronic transmission consented to by the stockholder to whom the notice is given and otherwise meeting the requirements set forth above, (A) if by facsimile transmission, when directed to a number at which the stockholder has consented to receive notice, (B) if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice, (C) if by a posting on an electronic network together with separate notice to the stockholder of such specified posting, upon the later of (1) such posting and (2) the giving of such separate notice, and (D) if by any other form of electronic transmission, when directed to the stockholder. A stockholder may revoke such stockholder’s consent to receiving notice by means of electronic communication by giving written notice of such revocation to the Corporation. Any such consent shall be deemed revoked if (1) the Corporation is unable to deliver by electronic transmission two consecutive notices given by the Corporation in accordance with such consent and (2) such inability becomes known to the Secretary or an assistant secretary or to the Corporation’s transfer agent, or other person responsible for the giving of notice; provided, however, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action.

C. Electronic Transmission. “Electronic Transmission” means any form of communication, not directly involving the physical transmission of paper, that creates a record that may be retained, retrieved and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such a recipient through an automated process, including but not limited to transmission by telex, facsimile telecommunication, electronic mail, telegram and cablegram.

D. Notice to the Stockholders Sharing Same Address. Without limiting the manner by which notice otherwise may be given effectively by the Corporation to stockholders, any notice to stockholders given by the Corporation under any provision of the DGCL, the Certificate of Incorporation or these By-laws shall be effective if given by a single written notice to stockholders who share an address if consented to by the stockholders at that address to whom such notice is given. A stockholder may revoke such stockholder's consent by delivering written notice of such revocation to the Corporation. Any stockholder who fails to object in writing to the Corporation within 60 days of having been given written notice by the Corporation of its intention to send such a single written notice shall be deemed to have consented to receiving such single written notice.

E. Exceptions to Notice Requirements. Whenever notice is required to be given, under the DGCL, the Certificate of Incorporation or these By-laws, to any person with whom communication is unlawful, the giving of such notice to such person shall not be required and there shall be no duty to apply to any governmental authority or agency for a license or permit to give such notice to such person. Any action or meeting which shall be taken or held without notice to any such person with whom communication is unlawful shall have the same force and effect as if such notice had been duly given. In the event that the action taken by the Corporation is such as to require the filing of a certificate with the Secretary of State of Delaware, the certificate shall state, if such is the fact and if notice is required, that notice was given to all persons entitled to receive notice except such persons with whom communication is unlawful.

Whenever notice is required to be given by the Corporation, under any provision of the DGCL, the Certificate of Incorporation or these By-laws, to any stockholder to whom (1) notice of two consecutive annual meetings of stockholders and all notices of stockholder meetings or of the taking of action by written consent of stockholders without a meeting to such stockholder during the period between such two consecutive annual meetings, or (2) all, and at least two payments (if sent by first-class mail) of dividends or interest on securities during a 12-month period, have been mailed addressed to such stockholder at such stockholder's address as shown on the records of the Corporation and have been returned undeliverable, the giving of such notice to such stockholder shall not be required. Any action or meeting which shall be taken or held without notice to such stockholder shall have the same force and effect as if such notice had been duly given. If any such stockholder shall deliver to the Corporation a written notice setting forth such stockholder's then current address, the requirement that notice be given to such stockholder shall be reinstated. In the event that the action taken by the Corporation is such as to require the filing of a certificate with the Secretary of State of Delaware, the certificate need not state that notice was not given to persons to whom notice was not required to be given pursuant to Section 230(b) of the DGCL. The exception in subsection (1) of the first sentence of this paragraph to the requirement that notice be given shall not be applicable to any notice returned as undeliverable if the notice was given by electronic transmission.

2. Waiver of notice. Whenever any notice is required to be given under applicable law, the Certificate of Incorporation, or these By-laws, a written waiver of such notice, signed before or after the date of such meeting by the person or persons entitled to said notice, or a waiver by electronic transmission by the person entitled to said notice, shall be deemed equivalent to such required notice. All such waivers shall be kept with the books of the Corporation. Attendance at a meeting shall constitute a waiver of notice of such meeting, except where a person attends for the express purpose of objecting to the transaction of any business on the ground that the meeting was not lawfully called or convened.

ARTICLE VI

INDEMNIFICATION

1. Right to Indemnification. The corporation shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person (a “Covered Person”) who was or is made or is threatened to be made a party or is or may be otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”), by reason of the fact that he or she, or a person for whom he or she is the legal representative, is or was a director or executive officer of the corporation or, while a director or executive officer of the corporation, is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or nonprofit entity, including service with respect to employee benefit plans, against all expenses (including attorneys’ fees, judgments, fines, and amounts paid in settlement) actually and reasonably incurred by such Covered Person. Notwithstanding the preceding sentence, except as otherwise provided in Section 3 hereof, the corporation shall be required to indemnify a Covered Person in connection with a proceeding (or part thereof) commenced by such Covered Person only if (a) such indemnification is expressly required to be made by law, (b) the commencement of such proceeding (or part thereof) by the Covered Person was authorized in the specific case by the Board of Directors of the corporation, or (c) such indemnification is required to be made pursuant to Section 3 of this Article VI.

2. Prepayment of Expenses. The corporation shall, to the fullest extent permitted by applicable law, pay the expenses (including attorneys’ fees) incurred by a Covered Person in defending any civil, criminal, administrative or investigative action, suit or proceeding in advance of its final disposition; provided, however, that, to the extent required by law, such payment of expenses in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking by the Covered Person to repay all amounts advanced if it should be ultimately determined that the Covered Person is not entitled to be indemnified under this Article VI or otherwise.

3. Enforcement/Claims. Without the necessity of entering into an express contract, all rights to indemnification and advancement of expenses to each Covered Person under this Article VI shall be deemed to be contractual rights and be effective to the same extent and as if provided for in a contract between the corporation and each Covered Person. If a claim for indemnification (following the final disposition of such action, suit or proceeding) or advancement of expenses under this Article VI is not paid in full within forty-five days after a written claim therefor by the Covered Person has been received by the corporation, the Covered Person may file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the reasonable expenses of prosecuting such claim. In any such action the corporation shall have the burden of proving that the Covered Person is not entitled to the requested indemnification or advancement of expenses under applicable law.

4. Nonexclusivity of Rights. The rights conferred on any Covered Person by this Article VI shall not be exclusive of any other rights which such Covered Person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, these By-laws, agreement, vote of stockholders or disinterested directors or otherwise.

5. Other Sources. The corporation’s obligation to indemnify or to advance expenses to any Covered Person or to any person who was or is serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or nonprofit entity shall be offset to the extent the indemnified party is indemnified or advanced expenses by any other source including but not limited to any applicable insurance coverage under a policy maintained by the corporation, the indemnified party or any other person including such other corporation, partnership, joint venture, trust, enterprise or non-profit enterprise.

6. Insurance. To the fullest extent permitted by law, the corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was a director, officer, employee or agent of the corporation serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, or other enterprise (including employee benefit plans) against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power or the obligation to indemnify such person against such liability under the provisions of this Article VI.

7. Certain Definitions. For purposes of this Article VI, the phrases and terms set forth in this Article VI shall be given the same meaning as the identical terms and phrases are given in Section 145 of the General Corporation Law of the State of Delaware, as that Section may be amended and supplemented from time to time. In addition, the following definitions shall apply to this Article VI:

(a) References to “executive officer” or “executive officers” shall have the meaning defined in Rule 3b-7 promulgated under the Securities Exchange Act of 1934, as amended.

(b) References to “expenses” shall be broadly construed and shall include, without limitation, court costs, attorneys’ fees, witness fees, fines, amounts paid in settlement or judgment and any other costs and expenses of any nature or kind incurred in connection with any proceeding.

(c) References to “proceeding” shall be broadly construed and shall include, without limitation, the investigation, preparation, prosecution, defense, settlement, arbitration and appeal of, and the giving of testimony, in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative.

8. Survival of Indemnification and Advancement of Expenses. The rights to indemnification and advancement of expenses conferred by this Article VI shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors, administrators and other personal and legal representatives of such a person.

9. Indemnification of Officers, Employees and Agents. The corporation may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification and to the advancement of expenses to officers, employees and agents of the corporation similar to those conferred in this Article VI to directors and executive officers of the corporation.

10. Effect of Amendment or Repeal. Neither any amendment or repeal of any section of this Article VI, nor the adoption of any provision of the certificate of incorporation or the By-laws inconsistent with this Article VI, shall adversely affect any right or protection of any director, executive officer, officer, employee or agent established pursuant to this Article VI existing at the time of such amendment, repeal or adoption of an inconsistent provision, including without limitation by eliminating or reducing the effect of this Article VI, for or in respect of any act, omission or other matter occurring, or any action or proceeding accruing or arising (or that, but for this Article VI, would accrue or arise), prior to such amendment, repeal or adoption of an inconsistent provision.

11. Saving Clause. If this Article VI or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the corporation shall nevertheless indemnify each director, executive officer, officer, employee or agent to the full extent not prohibited by any applicable portion of this Article VI that shall not have been invalidated, or by any other applicable law. If this Article VI shall be invalid due to the application of the indemnification provisions of another jurisdiction, then the corporation shall indemnify each director and executive officer to the full extent under any other applicable law.

ARTICLE VII

REIMBURSEMENT OR DISALLOWED DEDUCTIONS

Payments made to a corporate officer or Director (such as salary, commissions, bonus, interest, rent or expenses) which shall be disallowed by the Internal Revenue Service, in whole or in part, as a deductible expense for the purpose of corporate tax reporting, shall be reimbursed by such officer to the Corporation to the full extent of such disallowance. The Board of Directors shall take all necessary steps to enforce this repayment. In lieu of repayment by the officer or Directors, the Board of Directors, at its option, may withhold appropriate amounts from the officer’s or Director’s future compensation until payment has been recovered, provided the amount withheld is sufficient to extinguish the indebtedness within five years.

ARTICLE VIII

STOCK

1. Form. The shares of capital stock of the Corporation may be represented by certificates or be uncertificated. Every holder of stock in the Corporation shall be entitled to receive, if he, she or it so requests, a certificate or certificates representing his, her or its shares of capital stock of the Corporation in such form as may be prescribed by the Board of Directors. Certificates representing shares of stock in the corporate name shall be in such form as determined by the Board of Directors. All certificates shall be signed by the President or Vice-President, and by the Secretary or Treasurer. All certificates for such shares shall be consecutively numbered, and the name and address of the person to whom the shares represented thereby are issued together with the number of shares and date of issue, shall be entered on the stock transfer books of the Corporation.

Notwithstanding anything to the contrary in these By-laws, at all times that the Corporation’s stock is listed on a stock exchange, such shares shall comply with all direct registration system eligibility requirements established by such exchange, including any requirement that shares of the Corporation’s stock be eligible for issue in book-entry form. All issuances and transfers of shares of the Corporation’s stock shall be entered on the books of the Corporation with all information necessary to comply with such direct registration system eligibility requirements, including the name and address of the person to whom the shares are issued, the number of shares issued and the date of issue. The Board of Directors shall have the power and authority to make such rules and regulations as it may deem necessary or proper concerning the issue, transfer and registration of shares of stock of the Corporation in both the certificated and uncertificated form.

2. Transfer Agents, Registrars. Where a certificate is countersigned (1) by a transfer agent other than the Corporation or its employees, or, (2) by a registrar other than the Corporation or its employees, any other signature on the certificate may be facsimile. In case an officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if he were such officer, transfer agent or registrar at the date of issue.

3. Lost certificates. Each person claiming a certificate of stock to be lost or destroyed shall make an affidavit or affirmation of the fact and shall give the Corporation a bond in such sum as the Board of Directors may require to indemnify the Corporation against any claim that may be made against it on account of the alleged loss of the certificate. The Board of Directors may accept the affiant’s personal bond if it should appear that he or she possesses unencumbered property of sufficient value to assure indemnification. A new certificate, or such shares in uncertificated form, of the same tenor and for the same number of shares as the one alleged to be lost or destroyed shall then be issued.

4. Transfer of stock. Stock of the Corporation shall be transferable in the manner prescribed by law and in these By-laws. Except as otherwise established by rules and regulations adopted by the Board of Directors, and subject to applicable law, shares of stock may be transferred on the books of the Corporation, if such shares are certificated, upon surrender to the Corporation’s transfer agent or registrar of the Corporation’s share certificates, duly endorsed or accompanied by a written assignment or power of attorney properly executed, or upon proper instructions from the holder of uncertificated shares, in each case with such proof of authority or the authenticity of signature as the Corporation or its transfer agent may reasonably require.

5. Holder. The Corporation shall be entitled to treat the holder of record of any share or shares of stock as the holder in fact thereof and shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have the express or other notice thereof, except as otherwise provided by the laws of Delaware.

ARTICLE IX

2. Reserve for contingencies. Before payment of a dividend, the Board of Directors may set aside out of corporate funds available for dividends, such sum or sums as the Directors may, from time to time and in their discretion, deem proper, as a reserve fund to meet contingencies or for repairing or maintaining the corporate property, or for such other purposes as the Directors shall deem to be in the Corporation’s best interest.

ARRHYTHMIA RESEARCH TECHNOLOGY, INC.

ANNOUNCES RESULTS FOR FIRST QUARTER 2009

Fitchburg, MA

Arrhythmia Research Technology, Inc. (the “Company”) (AMEX: HRT) and its wholly owned subsidiary Micron Products, Inc. (“Micron”) reported total revenue of $4,683,000 and net income $82,000 for the quarter ended March 31, 2009 compared to total revenue of $5,460,000 and net income of $149,000 for the same quarter of 2008. Net income per share for the three months ended March 31, 2009 decreased to $ 0.03 per share from $ 0.06 per share for the same period in 2008.

James E. Rouse, the Company’s President and CEO commented, “The decline in revenue from the same period in 2008 was primarily the result of the elimination of an unprofitable product in our MIT division and continuing price erosion in Micron’s sensor sales. Although we were disappointed that our sensor revenue declined over the same period in 2008, we are encouraged by several developments. Sensor volume sales increased by 20% in the first quarter as compared to the same period in 2008. In addition, during the first quarter we were successful in securing a new long term supply agreement with one of our largest sensor customers. Although in its early stages, we are beginning to see the positive effects of the company-wide lean manufacturing training as well as results from our cost reduction teams developed as part of our continuing focus on improving gross margins on our existing product lines. As part of that process, we are also implementing technological and process improvements which are expected to be completed over the next six to nine months. We are cautiously optimistic that our continuing efforts to streamline manufacturing processes and concentrate on products, services and programs that meet our contribution and strategic goal will produce improved results. In addition, our very strong balance sheet positions us to not only weather the current economic climate but also to capitalize on future growth opportunities.”

The Company through its wholly owned subsidiary Micron Products, Inc. manufactures silver plated and non-silver plated conductive resin sensors and distributes metal snaps used in the manufacture of disposable ECG, EEG, EMS and TENS electrodes. Micron’s MIT division provides end- to- end product life cycle management through a comprehensive portfolio of value-added services such as design, engineering, prototyping, manufacturing, machining, assembly and packaging. MIT manufactures custom injection molded products for medical, electronic, industrial and consumer applications, and provides high end mold design, manufacturing and precision machining for various industries. The Company’s products also include proprietary signal-averaging electrocardiography (SAECG) software used in the detection of potentially lethal heart arrhythmias.
