For purposes of this Agreement, a “Material Adverse Effect” means any event, circumstance, change or effect individually or in the aggregate that has or would reasonably be expected to have a material adverse effect on the business, assets, properties, liabilities, results of operations or financial condition of the Company and its subsidiaries taken as a whole or impairs, prevents or delays the ability of the Company to perform its obligations hereunder, other than any event, circumstance, change or effect due to (A) general economic, market or political conditions, except in the event those conditions have a materially disproportionate effect on the Company and its subsidiaries, taken as a whole, as compared to other persons operating in the same industry, (B) matters generally affecting the industry in which the Company operates, except in the event those conditions have a materially disproportionate effect on the Company and its subsidiaries, taken as a whole, as compared to other persons operating in the same industry, (C) the announcement or expectation of this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby, including any termination of, reduction in or other negative impact on relationships, contractual or otherwise, with any funding sources, customers, suppliers, distributors, licensors, licensees, partners or employees of the Company or any of its subsidiaries to the extent related to the announcement or performance of this Agreement and the other Transaction Documents or the identity of Purchaser, (D) any of the requirements or limitations imposed on any party pursuant to this Agreement or the other Transaction Documents, including compliance with any covenants in this Agreement and such other Transaction Documents, (E) changes in applicable laws or regulations or in accounting policies or principles or in any interpretations of any of the foregoing, (F) any outbreak or escalation of war or armed hostilities or any act of terrorism, (G) earthquakes, hurricanes or other natural disasters or acts of God, (H) any failure by the Company to meet any published estimates or expectations as to revenues, earnings or other measures of financial or operating performance, (I) any failure by the Company to meet any projections, forecasts or budgets prepared by or on behalf of the Company, it being understood however that the factors giving rise to any such failure are not otherwise excluded by this clause (I) from the definition of “Material Adverse Effect” or (J) a decline in the Company’s stock price, in and of itself.

Section 2.2. Capitalization.

(a) The authorized capital stock of the Company consists of 90,000,000 shares of Common Stock and 5,000,000 shares of preferred stock, par value $0.001 per share (“Company Preferred Stock”).

Section 2.3. Subsidiaries.

(a) Section 2.3(a) of the Company Disclosure Schedule lists each subsidiary of the Company and sets forth with respect to each such subsidiary the jurisdiction of incorporation or organization, the authorized and outstanding capital stock of such subsidiary and the owner(s) of record of such outstanding capital stock. All the outstanding shares of capital stock (or other securities having by their terms voting power to elect a majority of directors or others performing similar functions) of each such subsidiary are owned by the Company, by another wholly-owned subsidiary of the Company or by the Company and another wholly-owned subsidiary of the Company, free and clear of all liens, charges, security interests, mortgages, pledges, options, preemptive rights, rights of first refusal or first offer, proxies, levies, voting trusts or agreements, or other adverse claims or restrictions on title or transfer of any nature whatsoever (collectively, “Encumbrances”), and are duly authorized, validly issued, fully paid and nonassessable. There are no securities convertible into or exchangeable for shares of capital stock or other securities of any subsidiary of the Company, or subscriptions, options, warrants, puts, calls, phantom stock rights, stock appreciation rights, stock-based performance units, agreements, understandings, claims or other commitments or rights of any type granted or entered into by the Company or any of its subsidiaries relating to the issuance, sale, repurchase or transfer of any securities of any subsidiary of the Company or that give any person or entity the right to receive any economic benefit or right similar to or derived from the economic benefits and rights of securities of any subsidiary of the Company. Except for the capital stock of its subsidiaries, the Company does not own, directly or indirectly, any capital stock or other ownership interest in any person. The Company is not subject to any obligation or requirement to provide funds to or make any investment (in the form of a loan, capital contribution or otherwise) in any person.

(b) Other than the shares of capital stock set forth in Section 2.3(a) of the Company Disclosure Schedule, no subsidiary of the Company has outstanding securities of any kind. No subsidiary of the Company is party to any contract obligating such subsidiary, directly or indirectly, to issue any additional securities and there is no circumstance or condition that may give rise to a claim by any person that such person is entitled to acquire the securities of any such subsidiary.

(c) No subsidiary of the Company has outstanding any bonds, debentures, notes or other obligations or debt securities the holders of which have the right to vote (or convertible into, or exercisable or exchangeable for, securities having the right to vote) on any matter.

Section 2.4. Validity of New Shares. When issued and paid for in accordance with the provisions of this Agreement, the New Shares will be duly authorized and validly issued, fully paid and nonassessable and free of any Encumbrances other than Encumbrances (i) imposed under applicable securities laws or (ii) imposed under any of the Transaction Documents.

Section 2.5. Authority.

(a) The Company has all requisite corporate power and authority to execute and deliver this Agreement and each other Transaction Document to which it is a party and to perform and consummate the transactions contemplated hereby and thereby. The execution, delivery and performance of this

Agreement and each other Transaction Document to which it is a party and the consummation by the Company of the transactions contemplated by this Agreement and the other Transaction Documents to which the Company is a party have been duly authorized by all necessary corporate action on the part of the Company and no other corporate proceedings on the part of the Company are necessary to authorize this Agreement or any other Transaction Document to which the Company is a party or to consummate transactions contemplated hereby and thereby, other than (i) the approval of the Company Stock Sale by a majority of the votes cast by all stockholders entitled to vote, as required under the rules of the NASDAQ Capital Market (the “Stock Sale Approval”); and (ii) the approval of the Charter Amendment by the affirmative vote of the holders of not less than 75% of the issued and outstanding shares of Common Stock (the “Charter Amendment Approval”). This Agreement, the Amended Bylaws and each other Transaction Document to which the Company is a party has been duly executed and delivered by the Company and, assuming the accuracy of the representations made in Section 3.2, constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms.

(b) The board of directors of the Company, at a meeting duly called and held, by the unanimous vote of all the directors present (i) adopted a resolution approving this Agreement, the Charter Amendment and each other Transaction Document to which the Company is a party, (ii) approved the Company Stock Sale, the other transactions contemplated hereby and the transactions contemplated by the Transaction Documents; (iii) determined that the Company Stock Sale is fair to, and in the best interests of, the Company and its stockholders; (iv) declared the Charter Amendment advisable; (v) took all actions necessary to render any anti-takeover statute or regulation inapplicable to each of the transactions contemplated by the Transaction Documents; and (vi) resolved to recommend that the Company’s stockholders vote in favor of the Company Stock Sale and the Charter Amendment.

(c) The board of directors of the Company has taken all actions so that the restrictions contained in Section 203 of the General Corporation Law of the State of Delaware (the “DGCL”) applicable to a “business combination” (as defined in such Section 203), and any other applicable law, will not apply to Purchaser or its affiliates with respect to the execution and delivery of this Agreement and the other Transaction Documents and the consummation of the transactions contemplated by this Agreement and the other Transaction Documents. No other anti-takeover statute or regulation applies to this Agreement and the other Transaction Documents and the consummation of the transactions contemplated by this Agreement and the other Transaction Documents. The Company does not have any stockholder rights plan in effect.

There are no pending or, to the knowledge of the Company, threatened or anticipated claims (other than routine claims for benefits) by, on behalf of or against any of the Benefit Plans or any trusts related thereto which would reasonably be expected to result in any liability of the Company or any subsidiary of the Company. Neither the Company nor its subsidiaries has agreed or otherwise committed to, whether in writing or otherwise, increase or improve the compensation, benefits or terms and conditions of employment or service of any director, officer, employee or consultant other than as required under an applicable Benefit Plan. Each Benefit Plan may be amended and terminated in accordance with its terms.

Section 4.2. No Solicitation.

(a) The Company agrees that from the date hereof through the Closing, (i) it and its subsidiaries shall not, and (ii) it shall cause its and its subsidiaries’ Representatives (as defined in Section 4.4(a)) to not, directly or indirectly, (x) solicit, initiate, seek, facilitate or encourage (including by way of providing information) the submission of any Takeover Proposal or any inquiries, proposals or offers that reasonably may be expected to lead to, any Takeover Proposal or (y) engage in any discussions or negotiations with respect thereto or otherwise cooperate with or assist or participate in, or facilitate any such inquiries, proposals, discussions or negotiations, or provide any confidential information relating to a Takeover Proposal. The Company shall, and shall direct each of its subsidiaries and each Representative to immediately cease any discussions, negotiations or communications with any party with respect to any Takeover Proposal and use commercially reasonable efforts to obtain the return from all such persons or cause the destruction of all copies of confidential information previously provided to such parties by the Company, its subsidiaries or its Representatives.

(b) Notwithstanding the provisions of Section 4.2(a), at any time prior to obtaining the Stock Sale Approval, in response to a written unsolicited Takeover Proposal received by the Company after the date hereof, (i) the Company may, directly or through officers or advisors, contact the person making such Takeover Proposal and its advisors solely for the purpose of clarifying the proposal and any material terms thereof and the capability of consummation, so as to determine whether the proposal for a Takeover Proposal is reasonably likely to lead to a Superior Proposal and (ii) if the Company’s board of directors determines in good faith following consultation with its legal and financial advisors that such Takeover Proposal is or is reasonably likely to lead to a Superior Proposal, the Company’s board of directors may (directly or through officers or advisors), after providing Purchaser with not less than 72 hours written notice of its intention to take such actions, (x) furnish nonpublic information with respect to the Company and the Company’s subsidiaries to the person that made such Takeover Proposal (provided, that the Company shall furnish such information pursuant to a confidentiality agreement no less favorable to the Company than the terms of the Confidentiality Agreement), (y) disclose to the Company’s stockholders any information required to be disclosed under applicable law and (z) participate in discussions and negotiations regarding such proposal.

(c) Except as set forth in this Section 4.2(c), neither the board of directors of the Company nor any committee thereof shall fail to make, withdraw or modify in a manner adverse to Purchaser the Recommendation (as defined below) or approve, recommend, or declare advisable any Takeover Proposal or authorize or permit the Company to enter into any letter of intent or other contract constituting a Takeover Proposal (other than a confidentiality and standstill agreement to the extent permitted by, and in accordance with, Section 4.2(a)), take any action or make any public statement inconsistent with the Recommendation, or resolve, agree to take or publicly propose to do any of the foregoing actions. Notwithstanding the foregoing, if prior to obtaining the Stock Sale Approval, the Company’s board of directors in good faith, after consultation with the Company’s legal advisors, determines that the failure to do so would be inconsistent with the directors’ duties under applicable law, the board may (i) withdraw, qualify or modify in a manner adverse to Purchaser, or fail to make, the Recommendation or recommend that the Company’s stockholders approve a Superior Proposal, (ii) cause the Company to terminate this Agreement and (iii) cause the Company to enter into a definitive agreement providing for or implementing a Superior Proposal, but only (x) not less than 72 hours after providing written notice to Purchaser advising Purchaser that the board of directors of the Company has received a Superior Proposal, specifying the material terms and conditions of such Superior Proposal and, identifying the person making such Superior Proposal, accompanied by a copy of the definitive agreement proposed to be entered into with the person making the Superior Proposal and (y) if the Company pays the Termination Fee as provided in Section 6.3.

(d) For purposes of this Agreement, “Takeover Proposal” means any of the following (other than the transactions expressly provided for in this Agreement): (i) any merger, consolidation, share exchange, business combination or similar transaction involving the Company; (ii) any sale, lease, exchange, mortgage, pledge, transfer or other disposition of 15% or more of the fair market value of the assets (including by means of an issuance, sale or other disposition of voting securities) of the Company and its subsidiaries, taken as a whole, or to which 15% or more of the Company’s revenues or earnings on a consolidated basis are attributable; (iii) any direct or indirect acquisition (whether in a single transaction or a series of transactions) of beneficial ownership (within the meaning of Section 13 under the Exchange Act) of 15% or more of any class of equity securities of the Company; or (iv) any tender offer or exchange offer that if consummated would result in any person or “group” (as defined in Section 13(d) of the Exchange Act) beneficially owning 15% or more of any class of voting securities of the Company.

(e) For purposes of this Agreement, “Superior Proposal” means a bona fide written proposal for a Takeover Proposal made by a third party after the date hereof that the Company’s board of directors determines (after taking into account any amendments to this Agreement entered into or which Purchaser irrevocably covenants to enter into and for which all internal approvals of Purchaser have been obtained prior to the date of such determination), in good faith and after consultation with its financial and legal advisors, is on terms that are more favorable to the Company’s stockholders than the Company Stock Sale (based upon the financial terms of such Takeover Proposal, the timing of and the availability of financing and the expectations of obtaining required approvals and such other considerations as the Company’s board of directors in the exercise of its fiduciary responsibilities deems relevant); provided, that for the purpose of the definition of “Superior Proposal”, the references to “15%” in the definition of “Takeover Proposal” shall be deemed to refer to 50%.

(f) The Company shall notify Purchaser of, promptly, but in no event later than three business days after receipt thereof, the material terms of any written proposal that any of the Company or any of its subsidiaries or its officers, directors, or Representatives or affiliates may receive after the date hereof relating to a Takeover Proposal and shall keep Purchaser reasonably informed as to the status of and any material developments regarding any such proposal.

(g) Nothing in this Section 4.2 or elsewhere in this Agreement shall prevent the Company’s board of directors from complying with Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act with respect to a Takeover Proposal or from issuing a stop, look and listen announcement or otherwise making any required disclosure to the Company stockholders if, in the good faith judgment of the Company’s board of directors, after consultation with outside legal counsel, failure to do so would be inconsistent with its obligations under applicable law, including Rule 14d-9 promulgated under the Exchange Act or Item 1012(a) of Regulation M-A.

(h) The Company agrees that any violations of the restrictions set forth in this Section 4.2 by any Representative of the Company or any of its subsidiaries shall be deemed to be a breach of this Section 4.2 by the Company.

(b) Except to the extent expressly permitted by Section 4.2, (i) the board of directors of the Company shall recommend that the Company’s stockholders vote in favor of the Company Stock Sale and the Charter Amendment Approval, and (ii) the Proxy Statement shall include a statement that the board of directors of the Company has recommended that the Company’s stockholders vote in favor of the Company Stock Sale and the proxy statement described in Section 4.9 shall include a statement that the board of directors of the Company has recommended that the Company’s stockholders vote in favor of the Charter Amendment Approval (this statement and the statement in the Proxy Statement, the “Recommendation”). Notwithstanding the foregoing, if prior to obtaining the Stock Sale Approval, the Company’s board of directors in good faith, after consultation with the Company’s legal advisors, determines that the failure to do so would be inconsistent with the directors’ duties under applicable law, the board may withdraw, qualify or modify, or fail to make the Recommendation. Regardless of whether the Company’s board of directors withdraws, qualifies or modifies, or fails to make the Recommendation, the Company shall submit the Company Stock Sale and the Charter Amendment Approval to the Company’s stockholders for their vote.

(c) The Company shall, as soon as reasonably practicable following the date of this Agreement, but no later than within fifteen business days from the date hereof, prepare and file a preliminary proxy statement (as subsequently amended, the “Proxy Statement”) with the SEC and thereafter each of the Company and Purchaser shall use their reasonable best efforts to respond to any comments of the SEC or its staff, and to any request by the SEC or its staff for amendments or supplements to the Proxy Statement or for additional information. The Proxy Statement and any amendments or supplements to the Proxy Statement will, when filed, comply as to form in all material respects with the applicable requirements of the Exchange Act.

Purchaser shall cooperate fully with the Company in the preparation of the Proxy Statement, including any amendment or supplement thereto, and shall furnish the Company, promptly upon the Company’s request, with all information reasonably requested by the Company for inclusion in, or otherwise in respect of, the Proxy Statement. Purchaser and its counsel shall be given a reasonable opportunity to review and comment upon the Proxy Statement and related proxy materials and any proposed amendment or supplement to the Proxy Statement prior to its filing with the SEC or dissemination to the Company’s stockholders, and reasonable and good faith consideration shall be given to any comments made by Purchaser and its counsel.

(d) Without limiting the generality of the foregoing, each of the parties shall correct promptly any information provided by it to be used in the Proxy Statement, if and to the extent any such information shall be or have become false or misleading in any material respect and shall take all steps necessary to correct the same and to cause the Proxy Statement as so corrected to be disseminated to the stockholders of the Company, in each case to the extent required by applicable law or otherwise deemed appropriate by the Company.

with such financial and other information and data concerning the Company and its subsidiaries and operations of the Company and its subsidiaries as Purchaser reasonably may request in writing.

Neither the Company nor any of its subsidiaries shall be required to provide access or to disclose information if doing so would in the Company’s reasonable opinion jeopardize any attorney-client or other legal privilege or contravene any law in the opinion of outside antitrust counsel reasonably would be expected to make it more difficult to obtain all requisite clearances, approvals and authorizations for the transactions contemplated by this Agreement, including under the HSR Act.

(b) Each party to this Agreement will hold, and will use its best efforts to cause its affiliates, and their respective Representatives to hold, in strict confidence from any person (other than any such affiliate or Representative), unless (i) compelled to disclose by judicial or administrative process (including in connection with obtaining the necessary approvals of this Agreement and the transactions contemplated hereby of Governmental Authorities) or by other requirements of law or (ii) disclosed in an action or proceeding brought by a party to this Agreement in pursuit of its rights or in the exercise of its remedies under this Agreement, all documents and information concerning the other party or any of its affiliates furnished to it by the other party or such other party’s Representatives in connection with this Agreement or the transactions contemplated hereby, except to the extent that such documents or information can be shown to have been (A) previously known by the party receiving such documents or information, (B) in the public domain (either prior to or after the furnishing of such documents or information hereunder) through no fault of such receiving party or (C) later acquired by the receiving party from another source if the receiving party is not aware that such source is under an obligation to another party hereto to keep such documents and information confidential; provided, however, that following the Closing the foregoing restrictions will not apply to Purchaser’s use of documents and information concerning the Company and its subsidiaries furnished by the Company under this Agreement. In the event the transactions contemplated by this Agreement are not consummated, upon the request of the other party, each party hereto will, and will cause its affiliates and their respective Representatives to, promptly redeliver or cause to be redelivered all copies of documents and information furnished by the other party in connection with this Agreement or the transactions contemplated hereby and destroy or cause to be destroyed all notes, memoranda, summaries, analyses, compilations and other writings related to such documents and information or based on such documents and information prepared by the party furnished such documents and information or its Representatives.

Each party shall (x) promptly notify the other party of any written communication to that party or its affiliates from any Governmental Authority and, subject to applicable law, permit the other party to review in advance any proposed written communication to any of the foregoing; (y) not agree to participate, or to permit its affiliates to participate, in any substantive meeting or discussion with any Governmental Authority in respect of any filings, investigation or inquiry concerning this Agreement unless it consults with the other party in advance and, to the extent permitted by such Governmental Authority, gives the other party the opportunity to attend and participate in such meeting; and (z) furnish the other party with copies of all correspondence, filings, and communications (and memoranda setting forth the substance thereof) between them and their affiliates and their respective Representatives on the one hand, and any Governmental Authority or members or their respective staffs on the other hand, with respect to this Agreement.

Section 4.7. Contact with Customers and Suppliers. Prior to the Closing, neither Purchaser nor any affiliate, officer, director, advisor, agent, employee or other representative of Purchaser shall contact any employee, customer, supplier or other person having a commercial relationship with the Company or any subsidiary without the consent of the Company, such consent not to be unreasonably withheld.

Section 4.8. Transfer Taxes. The responsibility for, and the payment obligation in connection therewith, all transfer, registration, stamp, documentary, sales, use and similar Taxes (including all applicable transfer Taxes), and any penalties, interest and additions to such Taxes, and fees incurred, levied or payable in connection with the transactions contemplated by this Agreement shall be borne and paid by Purchaser and Purchaser will at its own expense file or other otherwise submit all necessary returns and other documentation with respect to all such Taxes and fees.

Section 4.9. Charter Amendment Approval; Filing of the Certificate of Incorporation. As promptly as practicable following the Closing, the Company shall, in accordance with applicable law and its certificate of incorporation and bylaws, duly call, give notice of, convene and hold a meeting of its stockholders for the purpose of obtaining the Charter Amendment Approval. After promptly as reasonably practicable following the Charter Amendment Approval, the Company shall duly execute and file the Charter Amendment with the DSOS in accordance with the DGCL. The preliminary proxy statement for such stockholders’ meeting will be filed contemporaneously with the Proxy Statement described in Section 4.3 with the SEC and thereafter each of the Company and Purchaser shall use their

reasonable best efforts to respond to any comments of the SEC or its staff, and to any request by the SEC or its staff for amendments or supplements to such proxy statement or for additional information. Such proxy statement and any amendments or supplements to such proxy statement will, when filed, comply as to form in all material respects with the applicable requirements of the Exchange Act. If at any time prior to the stockholders’ meeting called to obtain the Charter Amendment Approval there shall occur any event that is required to be set forth in an amendment or supplement to such proxy statement, the Company shall promptly prepare, and, after consultation with Purchaser, mail to its stockholders such an amendment or supplement. Purchaser shall cooperate fully with the Company in the preparation of such proxy statement, including any amendment or supplement thereto, and shall furnish the Company, promptly upon the Company’s request, with all information reasonably requested by the Company for inclusion in, or otherwise in respect of, such proxy statement. Purchaser and its counsel shall be given a reasonable opportunity to review and comment upon such proxy statement and related proxy materials and any proposed amendment or supplement to such proxy statement prior to its filing with the SEC or dissemination to the Company’s stockholders, and reasonable and good faith consideration shall be given to any comments made by Purchaser and its counsel.

STOCKHOLDERS

Section 1.1. Place of Meetings. All meetings of stockholders shall be held at such place as may be designated from time to time by the Board of Directors, the Chairman of the Board or the Chief Executive Officer or, if not so designated, at the principal office of the corporation.

Section 1.2. Annual Meeting. The annual meeting of stockholders for the election of directors and for the transaction of such other business as may properly be brought before the meeting shall be held on a date and at a time designated by the Board of Directors, the Chairman of the Board, the Chief Executive Officer or the President (if the President shall be a different individual than the Chief Executive Officer) (which date shall not be a legal holiday in the place where the meeting is to be held). If no annual meeting is held in accordance with the foregoing provisions, a special meeting may be held in lieu of the annual meeting, and any action taken at that special meeting shall have the same effect as if it had been taken at the annual meeting, and in such case all references in these Bylaws to the annual meeting of the stockholders shall be deemed to refer to such special meeting.

Section 1.3. Special Meetings. Special meetings of stockholders for any purpose or purposes may be called at any time by the Board of Directors, the Chairman of the Board, the Chief Executive Officer or the President (if the President shall be a different individual than the Chief Executive Officer) or at the request in writing of stockholders owning at least fifty percent (50%) in amount of the entire capital stock of the corporation issued and outstanding and entitled to vote generally in the election of directors.

Section 1.4. Notice of Meetings. Except as otherwise provided by law, notice of each meeting of stockholders, whether annual or special, shall be given not less than 10 nor more than 60 days before the date of the meeting to each stockholder entitled to vote at such meeting. Without limiting the manner by which notice otherwise may be given to stockholders, any notice shall be effective if given by a form of electronic transmission consented to (in a manner consistent with the General Corporation Law of the State of Delaware) by the stockholder to whom the notice is given. The notices of all meetings shall state the place, date and time of the meeting and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting. The notice of a special meeting shall state, in addition, the purpose or purposes for which the meeting is called. If notice is given by mail, such notice shall be deemed given when deposited in the United States mail, postage prepaid, directed to the stockholder at such stockholder’s address as it appears on the records of the corporation. If notice is given by electronic transmission, such notice shall be deemed given at the time specified in Section 232 of the General Corporation Law of the State of Delaware.

Section 1.5. Voting List. The Secretary shall prepare, at least 10 days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least 10 days prior to the meeting: (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with notice of the meeting, or (ii) during ordinary business hours, at the principal place of business of the corporation. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

Section 1.6. Quorum. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, the holders of a majority in voting power of the shares of the capital stock of the corporation issued and outstanding and entitled to vote at the meeting, present in person, present by means of remote

communication in a manner, if any, authorized by the Board of Directors in its sole discretion, or represented by proxy, shall constitute a quorum for the transaction of business. A quorum, once established at a meeting, shall not be broken by the withdrawal of enough votes to leave less than a quorum.

Section 1.7. Adjournments. Any meeting of stockholders may be adjourned from time to time to any other time and to any other place at which a meeting of stockholders may be held under these Bylaws by the stockholders present or represented at the meeting and entitled to vote, although less than a quorum, or, if no stockholder is present, by any officer entitled to preside at or to act as secretary of such meeting. It shall not be necessary to notify any stockholder of any adjournment of less than 30 days if the time and place of the adjourned meeting, and the means of remote communication, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting, are announced at the meeting at which adjournment is taken, unless after the adjournment a new record date is fixed for the adjourned meeting. At the adjourned meeting, the corporation may transact any business which might have been transacted at the original meeting.

Section 1.8. Voting and Proxies. Each stockholder shall have one vote for each share of stock entitled to vote held of record by such stockholder and a proportionate vote for each fractional share so held, unless otherwise provided by law or the Certificate of Incorporation. Each stockholder of record entitled to vote at a meeting of stockholders may vote in person (including by means of remote communications, if any, by which stockholders may be deemed to be present in person and vote at such meeting) or may authorize another person or persons to vote for such stockholder by a proxy executed or transmitted in a manner permitted by the General Corporation Law of the State of Delaware by the stockholder or such stockholder’s authorized agent and delivered (including by electronic transmission) to the Secretary of the corporation. No such proxy shall be voted upon after three years from the date of its execution, unless the proxy expressly provides for a longer period.

Section 1.9. Action at Meeting. When a quorum is present at any meeting, any matter other than the election of directors to be voted upon by the stockholders at such meeting shall be decided by the affirmative vote of the holders of a majority in voting power of the outstanding shares of stock present or represented and voting on such matter (or if there are two or more classes of stock entitled to vote as separate classes, then in the case of each such class, the holders of a majority of the stock of that class present or represented and voting on such matter), except when a different vote is required by law, applicable rule, regulation or listing agreement, the Certificate of Incorporation or these Bylaws. When a quorum is present at any meeting, any election by stockholders of directors shall be determined by a plurality of the votes cast by the stockholders entitled to vote on the election.

Section 1.10. Nomination of Directors.

(a) Except for (i) directors nominated pursuant to the Governance Agreement, dated as of May 6, 2009, by and among the Corporation, Chiesi Farmaceutici SpA (“Chiesi SpA”) and the stockholders named therein (the “Governance Agreement”) while it is in effect, (ii) any directors entitled to be elected by the holders of preferred stock, (iii) any directors elected in accordance with Section 2.8 hereof by the Board of Directors to fill a vacancy or newly created directorships or (iv) as otherwise required by applicable law or stock market regulation, only persons who are nominated in accordance with the procedures in this Section 1.10 shall be eligible for election as directors.

(b) To be timely, a stockholder’s notice must be received in writing by the Secretary at the principal executive offices of the corporation as follows: (x) in the case of an election of directors at an annual meeting of stockholders, not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is advanced by more than 20 days, or delayed by more than 60 days, from the first anniversary of the preceding year’s annual meeting, a stockholder’s notice must be so received not earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of (A) the 90th day prior to such annual meeting and (B) the tenth day following the day on which notice of the date of such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever first occurs; or (y) in the case of an election of directors at a special meeting of stockholders, provided that the Board of Directors has determined that directors shall be elected as such meeting, not earlier than the 120th day prior to such special meeting and not later than the close of business on the later of (i) the 90th day prior to such special meeting and (ii) the tenth day following the day on which notice of the date of such special meeting was mailed or public disclosure of the date of such special meeting was made, whichever first occurs. In no event shall the adjournment or postponement of an annual or special meeting (or the public announcement thereof) commence a new time (or extend any time period) for the giving of a stockholder’s notice.

The stockholder’s notice to the Secretary shall set forth: (a) as to each proposed nominee (i) such person’s name, age, business address and, if known, residence address, (ii) such person’s principal occupation or employment, (iii) the class and number of shares of stock of the corporation which are beneficially owned by such person, and (iv) any other information concerning such person that must be disclosed as to nominees in proxy solicitations pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the “Exchange Act”); (b) as to the stockholder giving the notice (i) such stockholder’s name and address, as they appear on the corporation’s books, (ii) the class and number of shares of stock of the corporation which are owned, beneficially and of record, by such stockholder, (iii) a description of all arrangements or understandings between such stockholder and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination(s) are to be made by such stockholder, (iv) a representation that such stockholder intends to appear in person or by proxy at the meeting to nominate the person(s) named in its notice and (v) a representation whether the stockholder intends or is part of a group which intends (a) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the corporation’s outstanding capital stock required to elect the nominee and/or (b) otherwise to solicit proxies from stockholders in support of such nomination; and (c) as to the beneficial owner, if any, on whose behalf the nomination is being made (i) such beneficial owner’s name and address, (ii) the class and number of shares of stock of the corporation which are beneficially owned by such beneficial owner, (iii) a description of all arrangements or understandings between such beneficial owner and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination(s) are to be made and (iv) a representation whether the beneficial owner intends or is part of a group which intends (a) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the corporation’s outstanding capital stock requirement to elect the nominee and/or (b) otherwise to solicit proxies from stockholders in support of such nomination. In addition, to be effective, the stockholder’s notice must be accompanied by the written consent of the proposed nominee to serve as a director if elected.
