In addition, so long as the Investor and certain other holders affiliated with the Investor maintain at least one-half of the Investor’s initial equity investment in the Company, (a) such holders (the “Majority Investor Holders”) shall be entitled to certain (i) preemptive rights and rights of first offer on future equity and/or debt issuances by the Company and (ii) customary registration rights with respect to the common stock issuable upon conversion of the Series B Preferred Stock and (b) the consent of the majority of such holders will be required for (i) certain dividends or payments to other equity interests of the Company or to management or related parties, (ii) subject to certain exceptions, the authorization, issuance, or entrance into any agreement providing for the issuance of any debt or equity securities of the Company or any of its subsidiaries, (iii) certain reclassifications or recapitalizations of securities of the Company or its subsidiaries that would adversely affect the rights of the holders of the Series B Preferred Stock, (iv) certain asset disposals exceeding a specified threshold, (v) certain acquisitions exceeding a specified threshold, (vi) the entrance into certain material transactions involving Patni Computer Systems Limited (“Patni”) or the sale of Patni securities, (vii) certain changes in the line of business by the Company or any of its subsidiaries, (viii) the entrance into, amendment, modification or supplementation of certain agreements with related parties of the Company or any wholly-owned subsidiaries of the Company, (ix) the creation, incurrence, guarantee, assumption or issuance by the Company or any of its subsidiaries of certain additional indebtedness, (x) the hiring or termination of the Chief Executive Office or the Chief Financial Officer of the Company, (xi) the amendment or rescission of any provision of the certificate of incorporation, articles of incorporation, by-laws or similar organizational documents of the Company or any of its subsidiaries that would directly conflict with the terms and provisions of the Investor Rights Agreement or the Statement, (xii) the voluntary delisting of the Company’s stock from certain trading markets, (xiii) certain increases in the size of the Board, (xiv) the voluntary commencement of certain insolvency events, and (xv) the agreement to any of the foregoing.

Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

Article FIFTH of the Second Amended and Restated Articles of Incorporation of the Company (the “Articles of Incorporation”) authorizes the issuance from time to time of up to 20,000,000 shares of preferred stock, without par value. On January 31, 2011, the Company filed with the Pennsylvania Corporation Bureau a Statement with Respect to Shares (“Statement with Respect to Shares”) for the Series B Preferred Stock and set forth the voting and other powers, designations, preferences and relative, participating, optional or other rights, and the qualifications, limitations or restrictions, of the Series B Preferred Stock, which were not previously fixed by the Articles of Incorporation of the Company. The terms of the Statement with Respect to Shares modify and amend the Articles of Incorporation.

The Statement with Respect to Shares provides that the Series B Preferred Stock issued to the Investor is convertible into shares of the common stock, par value $0.01 per share (the “Common Stock”), of the Company at an initial conversion price of $20.30 per share (the “Conversion Price”). In addition to the right to participate in dividends and other distributions payable on the Common Stock on an as-converted basis, cumulative dividends will accrue on each share of Series B Preferred Stock at a rate of 8.0% per annum, which dividends will be added to the liquidation preference, and compounded quarterly. The Series B Preferred Stock will also have, among other things, (i) a Company option to convert the Series B Preferred Stock into Common Stock after eighteen months from the applicable closing date, if, among other things, the volume weighted average Common Stock price exceeds 205% of the Conversion Price for a specified period of time; (ii) a holder option to convert the outstanding principal plus accrued and unpaid dividends into

Common Stock at any time and from time to time; (iii) a holder put right at six years from the last occurring closing date for cash at an amount equal to the outstanding principal plus accrued and unpaid dividends; (iv) if the Series B Preferred Stock is not sooner converted, a mandatory conversion date at six years from the applicable closing date (subject to extension in limited cases) unless the holder exercises the put right described in clause (iii) above; and (v) the right to receive, prior to any payment in respect of any junior equity securities, the greater of the outstanding principal plus accrued and unpaid dividends and the as-converted value upon liquidation of the Company or upon certain changes of control.

Pursuant to the Statement with Respect to Shares, the holders of the Series B Preferred Stock benefit from customary anti-dilution and conversion price adjustment provisions in specified circumstances. Additionally, subject to certain exceptions and applicable law and exchange rules, the holders of Series B Preferred Stock shall be entitled to vote (a) on an as-converted basis with the holders of shares of Common Stock on all matters upon which shareholders of the Company are entitled to vote and (b) as a separate class with respect to the election of certain nominees to the Board.

Failure of the Company to comply with certain provisions of the Statement with Respect to Shares (including requirements relating to redemption payments, certain shareholder approvals, and certain requirements under the Investor Rights Agreement) may result, if not cured, in certain increases to the dividend accrual rate of the Series B Preferred Stock and, under certain circumstances and subject to applicable law and exchange rules, increased representation on the Board, in each case, for the duration of such noncompliance.

The foregoing summary description of the Series B Preferred Stock, the Series B Statement with Respect to Shares and the transactions contemplated thereby does not purport to be complete and is subject to and qualified in its entirety by reference to the Series B Statement with Respect to Shares, a copy of which is attached hereto as Exhibit 3.1 and the terms of which are incorporated herein by reference.
