DESCRIPTION OF CAPITAL STOCK

The following description of select provisions of (a) our Amended and Restated Articles of Incorporation, which we refer to as our articles of incorporation, (b) our Fifth Amended and Restated Bylaws, which we refer to as our bylaws, and (c) Georgia law is necessarily general and does not purport to be complete.

This summary is qualified in its entirety by reference in each case to the applicable provisions of our articles of incorporation and our bylaws. We have incorporated by reference our articles of incorporation and our bylaws as exhibits to the registration statement of which this prospectus forms a part.

General

Stock Outstanding. Our authorized capital stock consists of 950,000,000 shares, of which 750,000,000 are designated “Common Stock” and have a par value of $0.01 per share, and 200,000,000 shares are designated “Preferred Stock” and have a par value of $0.01 per share. As of June 15, 2022, 607,946,380 shares of Common Stock and no shares of Preferred Stock were issued and outstanding.

Common Stock

Holders of our Common Stock are entitled to receive dividends that may be declared and paid or set apart for payment upon the Common Stock out of any assets or funds of FIS legally available for the payment of dividends. Holders of our Common Stock have the right to vote for the election of directors and on all other matters requiring shareholder action, each share being entitled to one vote. Upon the voluntary or involuntary dissolution of FIS, the net assets of FIS available for distribution shall be distributed pro rata to the holders of the Common Stock in accordance with the number of shares of Common Stock held by them. The rights and privileges of holders of our Common Stock are subject to the rights and preferences of the holders of any series of Preferred Stock that we may issue in the future, as described below.

Preferred Stock

The Preferred Stock may be issued from time to time without shareholder consent by approval of our board of directors, which we refer to as our board, as shares of one or more series. The number of shares of each series of Preferred Stock, and the voting powers, designations, preferences, rights, qualifications, limitations and restrictions of or on such shares shall be as fixed and determined by our board prior to the issuance of any such shares, in the manner authorized by the Georgia Business Corporation Code, which we refer to as the Georgia Code. The authority of our board with respect to each series of the Preferred Stock includes, without limiting the generality of the foregoing, the establishment of any or all of the voting powers, preferences, designations, rights, qualifications, limitations and restrictions described in Section 14-2-601(d) of the Georgia Code, and any others determined by our board, any of which may be different from or the same as those of any other class or series of FIS’ shares.

Our board is expressly authorized at any time to adopt resolutions providing for the issuance of, or providing for a change in the number of, shares of any particular series of Preferred Stock and at any time and from time to time to file articles of amendment which are effective without shareholder action to increase or decrease the number of shares included in any series of Preferred Stock (but not to decrease the number of shares in any series below the number of shares then issued), to eliminate the series where no shares are issued, or to set or change in any one or more respects the voting powers, preferences, designations, rights, qualifications, limitations or restrictions relating to the shares of the series, except as otherwise provided by law or in the articles of amendment establishing any such series.

Anti-Takeover Effects of Certain Provisions of our Articles of Incorporation, our Bylaws and Georgia Law

A number of provisions of our articles of incorporation and our bylaws deal with matters of corporate governance and the rights of shareholders. The following discussion is a general summary of select provisions of

6

our articles of incorporation, our bylaws and certain Georgia law that might be deemed to have a potential “anti-takeover” effect. These provisions may have the effect of discouraging a future takeover attempt which is not approved by our board but which individual shareholders may deem to be in their best interest or in which shareholders may be offered a substantial premium for their shares over then-current market prices. As a result, shareholders who might desire to participate in such a transaction may not have an opportunity to do so. Such provisions also render the removal of the incumbent board or management more difficult.

Common Stock. Our unissued shares of authorized Common Stock will be available for future issuance without additional shareholder approval. While the authorized but unissued shares are not designed to deter or prevent a change of control, under some circumstances we could use the authorized but unissued shares to create voting impediments or to frustrate persons seeking to effect a takeover or otherwise gain control by, for example, issuing those shares in private placements to purchasers who might side with our board in opposing a hostile takeover bid.

Preferred Stock. The existence of authorized but unissued Preferred Stock could reduce our attractiveness as a target for an unsolicited takeover bid since we could, for example, issue shares of Preferred Stock to parties that might oppose such a takeover bid or issue shares of Preferred Stock containing terms the potential acquiror may find unattractive. This ability may have the effect of delaying or preventing a change of control, may discourage bids for our Common Stock at a premium over the market price of our Common Stock, and may adversely affect the market price of, and the voting and the other rights of the holders of, our Common Stock.

Board of Directors and Related Provisions. Our articles of incorporation provide that the number of directors is to be not less than five and not more than fifteen and is to be set by resolution of our board from time to time. Our articles of incorporation provide that any vacancy on our board that results from an increase in the number of directors, or from the death, resignation, retirement, disqualification, or removal from office of any director, will be filled by a majority of the remaining members of our board, though less than a quorum, or by the sole remaining director. Any director elected to fill a vacancy resulting from the death, resignation, retirement, disqualification, or removal from office of a director will have the same remaining term as his or her predecessor. Accordingly, our board can prevent any shareholder from enlarging our board and filling the new directorships with that shareholder’s own nominees.

Special Meetings of Shareholders. Our bylaws provide that special meetings of shareholders may be called by the chairman of our board, the vice chairman, our chief executive officer, our president, our board of directors by vote at a meeting of our board of directors, or a majority of our directors in writing without a meeting. Such special meetings may also be called by the holders of 100% of all the votes entitled to be cast on any issue proposed to be considered at the proposed special meeting, if such holders sign, date, and deliver to us one or more demands in writing or by electronic transmission for the meeting describing the purpose or purposes for which it is to be held. This provision could have the effect of inhibiting shareholder actions that require a special meeting of shareholders, unless our board, the chairman of our board, the vice chairman, our chief executive officer or our president calls such a special meeting.

Advance Notice Requirements for Shareholder Proposals and Director Nominees. Our bylaws provide that if one of our shareholders desires to submit a proposal or nominate persons for election as directors at an annual shareholders’ meeting, the shareholder’s written notice must be received by the secretary of FIS at the principal executive offices of FIS not less than 120 days prior to the first anniversary of the date that the proxy statement for the immediately preceding annual meeting of shareholders was released to shareholders. However, if no annual meeting of the shareholders was held in the previous year or if the date of the annual meeting of the shareholders has been changed by more than 30 days from the date contemplated at the time of the previous year’s proxy statement, the notice shall be delivered to and received by the secretary of FIS at the principal executive offices of FIS not later than the last to occur of (i) the date that is 150 days prior to the date of the contemplated annual meeting or (ii) the date that is 10 days after the date of the first public announcement or other notification to the shareholders of the date of the contemplated annual meeting. In the case of a special

7

meeting, to be timely, a shareholder’s proposal must be delivered to the secretary of FIS at the principal executive offices of FIS no later than the close of business on the earlier of (i) the 30th day following the public announcement that a matter will be submitted to a vote of the shareholders at a special meeting or (ii) the 10th day following the day on which notice of the special meeting was given. The notice must describe the proposal or nomination and set forth the name and address of, and the stock held of record and beneficially by, the shareholder, together with other specified information. Our board of directors may make such rules, regulations and procedures for the conduct of meetings of shareholders as it shall deem necessary, appropriate or convenient. Subject to any such rules, regulations and procedures established by our board of directors, the presiding officer of any meeting of the shareholders shall have the authority to, among other things, determine the order of business of the meeting and establish rules for, and appoint personnel to assist in, preserving the orderly conduct of the business of the meeting. In no event shall the adjournment, postponement or rescheduling of an annual or special meeting of shareholders (or the public announcement thereof) commence a new period (or extend any period) for the giving of a notice of nomination as described above. The advance notice requirements regulating shareholder nominations and proposals may have the effect of precluding a contest for the election of directors or the introduction of a shareholder proposal if the requisite procedures are not followed and may discourage or deter a third party from conducting a solicitation of proxies to elect its own slate of directors or to introduce a proposal.

Other Constituencies

In discharging the duties of their respective positions and in determining what is believed to be in the best interests of our company, our board, committees of our board, and individual directors, in addition to considering the effects of any action on FIS or its shareholders, are authorized under a provision of our articles of incorporation to consider the interests of our and our subsidiaries’ employees, customers, suppliers and creditors, the communities in which our offices or other establishments are located, and all other factors the directors consider pertinent. This provision permits our board to consider numerous judgmental or subjective factors affecting a proposal for a business combination, including some non-financial matters, and on the basis of these considerations, our board may be permitted to oppose a business combination or other transaction which, viewed exclusively from a financial perspective, might be attractive to some, or even a majority, of our shareholders.

Amendment of Our Articles of Incorporation

Under the Georgia Code, and except as otherwise provided by our articles of incorporation, amendments to our articles of incorporation generally require the amendment to be recommended to the shareholders by our board and approved at a properly called shareholder meeting by a majority of the votes entitled to be cast on the amendment by each voting group entitled to vote on the amendment.

The Georgia Code provides that certain minor amendments to a corporation’s articles of incorporation may be adopted by the board without shareholder action.

Amendment of Our Bylaws

Under the Georgia Code in general, and subject to our articles of incorporation and the requirements of the business combination and fair price provisions described below, our bylaws may be altered, amended, or repealed by our board or by the affirmative vote of a majority of votes cast by shareholders entitled to vote thereon, where a quorum is present.

Anti-Takeover Legislation - Georgia Law

We are covered by two provisions of the Georgia Code that restrict business combinations with interested shareholders: the business combination provision and the fair price provision. These provisions do not apply to a Georgia corporation unless its bylaws specifically make the statute applicable, and once adopted, in addition to any other vote required by the corporation’s articles of incorporation or bylaws to amend the bylaws, such a

8

bylaw may be repealed only by the affirmative vote of at least two-thirds of the continuing directors and a majority of the votes entitled to be cast by the voting shares of such corporation, other than shares beneficially owned by an interested shareholder and, with respect to the fair price provision, his, her, or its associates and affiliates.

Interested Shareholders Transactions

The business combination provision of the Georgia Code generally prohibits Georgia corporations from entering into certain business combination transactions with any “interested shareholder,” generally defined as any person other than the corporation or its subsidiaries beneficially owning at least 10% of the outstanding voting stock of the corporation, for a period of five years from the date that person became an interested shareholder, unless:

For purposes of this provision, Insider Shares refers generally to shares owned by:

A Georgia corporation’s bylaws must specify that all requirements of this provision apply to the corporation in order for this provision to apply. Our bylaws contain a provision stating that all requirements of this provision, and any successor provision, apply to us.

Fair Price Requirements

The fair price provision of the Georgia Code imposes certain requirements on business combinations of a Georgia corporation with any person who is an “interested shareholder” of that corporation. In addition to any vote otherwise required by law or the corporation’s articles of incorporation, under the fair price provision, business combinations with an interested shareholder must meet one of the three following criteria designed to protect a corporation’s minority shareholders:

9

A Georgia corporation’s bylaws must specify that all requirements of the fair price provision apply to the corporation in order for the fair price provision to apply. Our bylaws contain a provision stating that all requirements of the fair price provision, and any successor provisions thereto, apply to us.

Removal of Directors

The Georgia Code also contains a provision commonly referred to as the “removal provision,” which, in the case of a company such as FIS without a staggered board, generally provides that:

Limitations on Director Liability

Under the provisions of our articles of incorporation, no director shall have any liability to us or to our shareholders for monetary damages for any action taken, or failure to take any action, as a director, except for: (1) any appropriation of any business opportunity of ours in violation of the director’s duties; (2) acts or omissions which involve intentional misconduct or a knowing violation of law; (3) the types of liability set forth in Section 14-2-832 of the Georgia Code (relating to a director’s personal liability for certain corporate distributions); or (4) any transaction from which the director received an improper personal benefit.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

DESCRIPTION OF PURCHASE CONTRACTS

As may be specified in a prospectus supplement, we may issue purchase contracts obligating holders to purchase from us, and us to sell to the holders, a number of debt securities, shares of common stock or preferred stock, or other securities described in this prospectus or the applicable prospectus supplement at a future date or dates. The prospectus supplement relating to any purchase contracts will specify the material terms of the purchase contracts and any applicable pledge or depositary arrangements.

PLAN OF DISTRIBUTION

We may sell the securities being offered hereby in one or more of the following ways from time to time:

The securities may also be offered and sold, if so indicated in the prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us. The prospectus supplement will identify any remarketing firm and will describe the terms of its agreement, if any, with us and its compensation.

Unless otherwise stated in a prospectus supplement, the obligations of the underwriters to purchase any securities will be conditioned on customary closing conditions and the underwriters will be obligated to purchase all of such series of securities, if any are purchased.

If we sell the securities directly or through agents designated by us, we will identify any agent involved in the offering and sale of the securities and will list any commissions payable by us to the agent in the accompanying prospectus supplement. Unless indicated otherwise in the prospectus supplement, any such agent will be acting on a best-efforts basis to solicit purchases for the period of its appointment.

We may authorize agents, underwriters or dealers to solicit offers by certain institutional investors to purchase securities and provide for payment and delivery on a future date specified in an accompanying prospectus supplement. We will describe any such arrangement in the prospectus supplement. Any such

12

institutional investor may be subject to limitations on the minimum amount of securities that it may purchase or on the portion of the aggregate principal amount of such securities that it may sell under such arrangements. Institutional investors from which such authorized offers may be solicited include:

Underwriters, dealers, agents and remarketing firms, and their control persons, may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the underwriters, dealers, agents and remarketing firms may be required to make. Underwriters, dealers, agents and remarketing agents may be customers of, engage in transactions with, or perform services for us or our affiliates in the ordinary course of business.

Each series of securities will be a new issue of securities and will have no established trading market other than our Common Stock which is listed on the New York Stock Exchange.

The applicable prospectus supplement will describe the plan of distribution with regard to any shares to be sold by selling shareholders.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The expenses relating to the registration of the securities will be borne by the registrant. Such expenses are estimated to be as follows:

Georgia Business Corporation Code. Subsection (a) of Section 14-2-851 of the Georgia Business Corporation Code (the “Georgia Code”) provides that a corporation may indemnify an individual who is a party to a proceeding because he or she is or was a director against liability incurred in the proceeding if: (1) such individual conducted himself or herself in good faith; and (2) such individual reasonably believed: (A) in the case of conduct in his or her official capacity, that such conduct was in the best interests of the corporation; (B) in all other cases, that such conduct was at least not opposed to the best interests of the corporation; and (C) in the case of any criminal proceeding, that the individual had no reasonable cause to believe such conduct was unlawful. Subsection (c) of Section 14-2-851 of the Georgia Code provides that the termination of a proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, is not, of itself, determinative that the director did not meet the standard of conduct described in Section 14-2-851 of the Georgia Code. Subsection (d) of Section 14-2-851 of the Georgia Code provides that a corporation may not indemnify a director: (1) in connection with a proceeding by or in the right of the corporation, except for reasonable expenses incurred in connection with the proceeding if it is determined that the director has met the relevant standard of conduct; or (2) in connection with any proceeding with respect to conduct for which he or she was adjudged liable on the basis that personal benefit was improperly received by him or her, whether or not involving action in his or her official capacity. Notwithstanding the foregoing, pursuant to Section 14-2-854 of the Georgia Code, a court shall order a corporation to indemnify or give an advance for expenses to a director if, after application by a director for indemnification or advancement of expenses, such court determines the director is entitled to indemnification under the indemnification provisions of the Georgia Code or if it determines that in view of all relevant circumstances, it is fair and reasonable, even if the director has not met the standard of conduct set forth in subsections (a) and (b) of Section 14-2-851 of the Georgia Code or was adjudged liable in a proceeding referred to in paragraph (1) or (2) of subsection (d) of Section 14-2-851 of the Georgia Code, but if the director was adjudged so liable, the indemnification shall be limited to reasonable expenses incurred in connection with the proceeding.

II-1

Section 14-2-852 of the Georgia Code provides that a corporation shall indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the director was a party because he or she was a director of the corporation against reasonable expenses incurred by the director in connection with the proceeding. Section 14-2-857 of the Georgia Code provides that a corporation may indemnify and advance expenses to an officer of the corporation who is a party to a proceeding because he or she is an officer of the corporation to the same extent as a director. If the officer is not a director (or if the officer is a director but the sole basis on which he or she is made a party to the proceeding is an act or omission solely in his or her capacity as an officer), the corporation may also indemnify and advance expenses to such officer to such further extent as may be provided by the articles of incorporation, the bylaws, a resolution of the board of directors, or contract, except for liability arising out of conduct that constitutes: (A) appropriation, in violation of his or her duties, of any business opportunity of the corporation; (B) acts or omissions which involve intentional misconduct or a knowing violation of law; (C) the types of liability set forth in Section 14-2-832 of the Georgia Code, or (D) receipt of an improper personal benefit. Subsection (c) of Section 14-2-857 of the Georgia Code provides that an officer of the corporation who is not a director is entitled to mandatory indemnification under Section 14-2-852 of the Georgia Code and may apply to a court under Section 14-2-854 of the Georgia Code for indemnification or advances for expenses, in each case to the same extent to which a director may be entitled to indemnification or advances for expenses under those provisions. Finally, a corporation may also indemnify an employee or agent who is not a director to the extent, consistent with public policy, that may be provided by its articles of incorporation, bylaws, general or specific action by its board of directors, or contract.

FIS’ Bylaws. Article V of FIS’ bylaws requires FIS to indemnify and hold harmless any director or officer who was or is a party or is threatened to be made a party, to any threatened, pending, or completed action, suit or proceeding whether civil, criminal, administrative, or investigative, including any action or suit by or in the right of FIS, because such person is or was a director or officer of FIS against liability incurred in such proceeding. FIS’ bylaws generally prohibit FIS from indemnifying any officer or director who is adjudged liable to FIS or is subjected to injunctive relief in favor of FIS for:

In each case, if any person is entitled to indemnification by FIS for some portion of liability incurred, but not the total amount thereof, FIS shall indemnify such person for the portion of such liability to which such person is entitled.

FIS’ bylaws require FIS, under certain circumstances, to advance expenses to its officers and directors who are parties to an action, suit, or proceeding for which indemnification may be sought. The indemnification provided by the Georgia Code and FIS’ bylaws is not exclusive of any other rights to which a director or officer of FIS may be entitled. FIS’ directors and officers are insured against losses arising from any claim against them as such for wrongful acts or omissions, subject to certain limitations.

The Debt Securities may be issued in one or more series pursuant to (i) a senior indenture among the Company, certain other persons and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Senior Indenture”), or (ii) a subordinated indenture to be entered into between the Company and The Bank of New York Mellon Trust Company, N.A. (the “Subordinated Indenture” and, together with the Senior Indenture, the “Indentures”), each of which is incorporated by reference as an exhibit to the Registration Statement. The Depositary Shares evidenced by Receipts may be issued pursuant to a Deposit Agreement (the “Deposit Agreement”) between the Company and a depositary, which will be filed as an exhibit to the Registration Statement when such Depositary Shares are issued. The Warrants may be issued pursuant to one or more warrant agreements (each, a “Warrant Agreement”) to be entered into between the Company and a warrant agent or agents, which will be filed as an exhibit to the Registration Statement when such Warrants are issued. The Purchase Contracts may be issued pursuant to a Purchase Contract Agreement to be entered into between the Company and a bank or trust company as Purchase Contract Agent and a Pledge Agreement to be entered into between the Company, a Purchase Contract Agent and a bank or trust company as Collateral Agent, Custodial Agent and Securities Intermediary, each of which will be filed as an exhibit to the Registration Statement when such Purchase Contracts are issued. The Units may be issued pursuant to a Unit Agreement to be entered into between the Company and a bank or trust company as Unit Agent, which will be filed as an exhibit to the Registration Statement when such Units are issued.

We have examined such corporate records, certificates and other documents as we have considered necessary for the purposes hereof. In such examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as copies and the authenticity of the originals of such latter documents. As to any facts material to our opinions, we have, when relevant facts were not independently established, relied upon the aforesaid records, certificates and documents.

Based upon and subject to the foregoing, and subject to the further limitations, qualifications and assumptions set forth below, we are of the opinion that:

1. Assuming that the Indentures, any Debt Securities and any supplemental indenture to be entered into in connection with the issuance of such Debt Securities have been duly authorized, when (i) the Registration Statement has become effective under the Securities Act, (ii) the applicable Indenture and a supplemental indenture in respect of such Debt Securities have been duly executed and delivered, (iii) the terms of such Debt Securities have been duly established in accordance with the applicable Indenture and the applicable supplemental indenture relating to such Debt Securities in a manner that does not violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and that complies with any requirement or restriction imposed by any court or governmental or regulatory body having jurisdiction over the Company and (iv) such Debt Securities have been duly executed and authenticated in accordance with the applicable Indenture and the applicable supplemental indenture relating to such Debt Securities and duly issued, paid for and delivered in the manner contemplated in the Registration Statement and any prospectus supplement relating thereto, and in accordance with any underwriting agreement and the terms of any other Offered Securities pursuant to which Debt Securities may be issued, such Debt Securities (including any Debt Securities duly issued upon exchange or conversion of any shares of Preferred Stock or Warrants that are exchangeable or convertible into Debt Securities) will constitute valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other similar laws affecting the enforcement of creditors’ rights generally and to general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law).

Assuming that a Deposit Agreement relating to the Depositary Shares (the “Deposit Agreement”) has been duly authorized, when (i) the Registration Statement has become effective under the Securities Act, (ii) the Deposit Agreement has been duly executed and delivered, (iii) the terms of such Depositary Shares and of their issuance and sale have been duly established in conformity with the Deposit Agreement relating to such Depositary Shares and do not violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and comply with any requirement or restriction imposed by any court or governmental or regulatory body having jurisdiction over the Company, (iv) (a) the Debt Securities relating to such Depositary Shares have been duly and properly authorized for issuance as contemplated in paragraph 1 above or (b) the shares of Preferred Stock relating to such Depositary Shares have been duly and properly authorized for issuance and are fully paid and non-assessable, (v) such Preferred Stock or the Debt Securities have been issued, paid for and delivered in the manner contemplated in the Registration Statement and any prospectus supplement relating thereto and in accordance with any underwriting agreement and the terms of any Offered Securities pursuant to which the Debt Securities or shares of Preferred Stock, as the case may be, may be issued and (vi) the Receipts evidencing such Depositary Shares are issued against the deposit of such Preferred Stock or the Debt Securities as contemplated in the Registration Statement and any prospectus supplement relating thereto, and in accordance with the Deposit Agreement, any underwriting agreement and the terms of any Offered Securities relating to such issuance, such Receipts evidencing the Depositary Shares (including any Depositary Shares that may be issued upon exercise, conversion, exchange or otherwise pursuant to the terms of any other Offered Securities) will be validly issued and will entitle the holders thereof to the rights specified therein and in the Deposit Agreement.

3. Assuming that the Warrants and the terms of the offering thereof and related matters have been duly authorized, and their terms and the terms of their issuance and sale do not violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and comply with any requirement or restriction imposed by any court or governmental or regulatory body having jurisdiction over the Company, when (i) the Registration Statement has become effective under the Securities Act, (ii) the Warrant Agreement or Agreements relating to the Warrants have been validly executed and delivered by the Company and the Warrant Agent appointed by the Company, and (iii) the Warrants or certificates representing the Warrants have been executed, authenticated, issued, paid for and delivered as contemplated in the Registration Statement and any prospectus supplement relating thereto, and in accordance with any underwriting agreement, such Warrants will constitute valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other similar laws affecting the enforcement of creditors’ rights generally and to general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law).

5. Assuming that Units and the terms of the offering thereof and related matters have been duly authorized, and their terms and the terms of their issuance and sale do not violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and comply with any requirement or restriction imposed by any court or governmental or regulatory body having jurisdiction over the Company, when (i) the Registration Statement has become effective under the Securities Act, (ii) the other Offered Securities that are a component of such Units have been duly and properly authorized for issuance and, in the case of Common Stock and Preferred Stock, will, upon the issuance of the Units be, fully paid and non-assessable, (iii) in the case of Units consisting at least in part of debt obligations of third parties, such debt obligations at all relevant times constitute the valid and binding obligations of the issuers thereof enforceable against the issuers thereof in accordance with their terms, and (iv) the Units have been executed, authenticated, and if required, issued, paid for and delivered as contemplated in the Registration Statement and any prospectus supplement relating thereto, and in accordance with any underwriting agreement, such Units will constitute valid and binding obligations of the Company enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other similar laws affecting the enforcement of creditors’ rights generally and to general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law).

We express no opinion as to the laws of any jurisdiction other than the laws of the State of New York and the federal laws of the United States of America.

We express no opinion as to the application of the securities or blue sky laws of the several states to the sale of the Offered Securities. Without limiting the generality of the foregoing, except as set forth herein, we express no opinion in connection with the matters contemplated by the Registration Statement, and no opinion may be implied or inferred, except as expressly set forth herein.

When (i) the Registration Statement has become effective under the Securities Act, (ii) amendments to the Company’s articles of incorporation determining the terms of the series of Preferred Stock have been filed with the Secretary of State of the State of Georgia and the shares of such series of Preferred Stock have been duly and properly authorized for issuance, (iii) such issuance does not violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and complies with any requirement or restriction imposed by any court or governmental or regulatory body having jurisdiction over the Company and (iv) such shares of Preferred Stock have been issued, paid for and delivered in the manner contemplated in the Registration Statement and any prospectus supplement relating thereto, and in accordance with any underwriting agreement and the terms of any other Offered Securities pursuant to which shares of Preferred Stock may be issued, such shares of Preferred Stock (including any Preferred Stock duly issued upon exchange for, conversion of or exercise of Debt Securities, Warrants, Purchase Contracts or Units) will be validly issued, fully paid and nonassessable.
