SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
This prospectus, any applicable prospectus supplement and the documents incorporated by reference herein contain forward-looking statements within the meaning of Section 21E of the Exchange Act and Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), that involve risks and uncertainties. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance and business. You can identify these statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe” and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events. All statements other than statements of historical facts included in this prospectus that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements.

Table of Contents
These forward-looking statements are largely based on our expectations and beliefs concerning future events, which reflect estimates and assumptions made by our management. These estimates and assumptions reflect our best judgment based on currently known market conditions and other factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control. Although we believe our estimates and assumptions to be reasonable, they are inherently uncertain and involve a number of risks and uncertainties that are beyond our control. In addition, management’s assumptions about future events may prove to be inaccurate. Management cautions all readers that the forward-looking statements contained in this prospectus are not guarantees of future performance, and we cannot assure any reader that those statements will be realized or the forward-looking events and circumstances will occur. Actual results may differ materially from those anticipated or implied in the forward-looking statements due to the factors listed in the “Risk Factors” section and elsewhere in this prospectus and factors listed in “Business” and “Risk Factors” in our most recent Annual Report on Form 10-K and any subsequently filed Quarterly Reports on Form 10-Q, which are incorporated by reference into this prospectus, as the same may be updated from time to time by our future filings under the Exchange Act.
You should read these risk factors and the other cautionary statements made in this prospectus, any applicable prospectus supplement and the documents incorporated by reference herein as being applicable to all related forward-looking statements wherever they appear in this prospectus, any applicable prospectus supplement and the documents incorporated by reference herein. We cannot assure you that the forward-looking statements in this prospectus will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified time frame, if at all.
The forward-looking statements made in this prospectus, any applicable prospectus supplement and the documents incorporated by reference herein relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events, except to the extent required by applicable securities law. These cautionary statements qualify all forward-looking statements attributable to us or persons acting on our behalf.

SELLING STOCKHOLDERS
The following table sets forth information with respect to the beneficial ownership of our common stock held as of March 31, 2017 by the selling stockholders, the number of shares of common stock being offered hereby and information with respect to common stock to be beneficially owned by the selling stockholders assuming all the Common Shares registered hereunder are sold. The amounts and percentages of common stock beneficially owned are reported on the basis of SEC regulations governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has the right to acquire beneficial ownership within 60 days. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which he or she has no economic interest.
The percentages in the following table reflect the common stock beneficially owned by the selling stockholders as a percentage of the total number of shares of our common stock held and, to the extent applicable, issuable to the selling stockholders upon the exercise or conversion of any of our securities that are exercisable or convertible within 60 days of March 31, 2017. As of March 31, 2017, we had 33,553,688 shares of common stock outstanding.

DESCRIPTION OF CAPITAL STOCK
The following description of our capital stock and provisions of our certificate of incorporation and our bylaws are summaries and are qualified by reference to the certificate of incorporation and the bylaws, which documents are incorporated by reference as exhibits to the registration statement of which this prospectus is a part, and the applicable provisions of the Delaware General Corporation Law (DGCL).
Our authorized capital stock consists of 150,000,000 shares of common stock, par value $0.01 per share and 5,000,000 shares of undesignated preferred stock, par value $0.01 per share, the rights and preferences of which may be established from time to time by our board of directors. As of March 31, 2017, there were 33,553,688 shares of common stock and no shares of preferred stock issued and outstanding.
The following description summarizes the terms of our capital stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description, you should refer to our certificate of incorporation and bylaws, copies of which have been filed as exhibits to the registration statement of which this prospectus is a part.
Common Stock
Holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders. Our stockholders do not have cumulative voting rights in the election of directors. Except as required by law or our certificate of incorporation and bylaws, the vote of a majority of the shares represented in person or by proxy at any meeting at which a quorum is present will be sufficient for the transaction of any business at a meeting. Subject to preferences held by, or that may be granted to, any outstanding shares of preferred stock, holders of our common stock will be entitled to receive ratably those dividends as may be declared by our board of directors out of funds legally available for such distributions, as well as any other distributions made to our stockholders. In the event of our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in all of our assets remaining after we pay our liabilities and any liquidation preferences granted to the holders of outstanding shares of preferred stock. Holders of our common stock have no preemptive or other subscription or conversion rights. There are no redemption or sinking fund provisions applicable to our common stock. All shares of our common stock that are outstanding on the date of this prospectus are fully paid and non-assessable.
Preferred Stock
Our certificate of incorporation authorizes the issuance of 5,000,000 shares of blank check preferred stock with such designation, rights and preferences as may be determined from time to time by our board of directors. No shares of preferred stock are being issued or registered in this offering. Accordingly, our board of directors is empowered, without stockholder approval, to issue preferred stock with dividend, liquidation, conversion, voting or other rights which could adversely affect the voting power or other rights of the holders of common stock. The preferred stock could be utilized as a method of discouraging, delaying or preventing a change in control of us. Although we do not currently intend to issue any shares of preferred stock, there can be no assurance that we will not do so in the future.

Table of Contents
Registration Rights
Pursuant to the Registration Rights Agreement, the selling stockholders have certain rights with respect to the registration of their shares of our common stock under the Securities Act.
Demand Registration Rights. Commencing 90 days following the completion of a firm commitment underwritten public offering of our securities pursuant to an effective registration statement filed by us under the Securities Act resulting in gross proceeds of at least $75.0 million to us, any holder who is a party to the Registration Rights Agreement who holds registrable securities has the right to demand that we file a registration statement covering the resale of its common stock, provided that a minimum of 20% of the common stock covered by the Registration Rights Agreement are included in such request, subject to a maximum of four such demands in the aggregate for all holders and to other specified exceptions. Provided that we are eligible for the use of SEC Form S-3, any holder who is a party to the Registration Rights Agreement who holds registrable securities, has the right to demand that we file with the SEC a registration statement under SEC Form S-3 or any similar short-form registration statement covering the shares of common stock held by these stockholders to be offered to the public, subject to specified exceptions. At the request of the holders, a demand registration may be a shelf registration pursuant to Rule 415 of the Securities Act.
The underwriters of any such offerings will have the right to limit the number of shares to be offered except that if a limit is imposed, then only shares held by holders who are parties to the Registration Rights Agreement who holds registrable securities will be included in such offering and the number of shares to be included in such offering will be allocated pro rata among those same parties. In any event, we will not include any securities of any other person (including us) in any demand registration statement without the prior written consent of the holders of a majority of the shares of common stock covered by such demand registration statement.
In no event will we be required to effect more than one demand registration under the Registration Rights Agreement within any three-month period (or within a given one-month period, in the case of any registration under Form S-3 or any similar short-form registration statement), and we will not be obligated to effect any demand registration unless the aggregate gross proceeds to be received from the sale of common stock equals or exceeds $10.0 million (or $1.0 million, in the case of any registration under Form S-3 or any similar short-form registration statement).
Piggyback Registration Rights. If we register any equity securities for our own account for public sale, stockholders with registration rights will, with specified exceptions, have the right to include their shares in the registration statement. The underwriters of any underwritten offering will have the right to limit the number of such shares to be included in the registration statement if the inclusion of all common stock of the holders who are a party to the Registration Rights Agreement who holds registrable securities proposed to be included in such offering would materially and adversely interfere with the successful marketing of our securities. Priority of inclusion in the registration shall be given first to us, second to stockholders with registration rights,  pro rata  on the basis of the relative number of securities requested to be registered by such stockholder, and third to any other participating person on such basis as we determine.
Expenses of Registration. Other than underwriting fees, discounts, commissions, stock transfer taxes and fees and disbursements of legal counsel to participating holders (excluding the fees of one firm of legal counsel to all of the participating holders participating in an underwritten public offering), we will pay all expenses relating to demand registrations and all expenses relating to piggyback registrations.

Indemnification and Contribution. The Registration Rights Agreement contains indemnification and contribution arrangements between us and stockholders who are a party to the Registration Rights Agreement who holds registrable securities with respect to each registration statement.
Anti-takeover Effects of Delaware Law and our Certificate of Incorporation and Bylaws
The provisions of Delaware law, our certificate of incorporation and our bylaws described below may have the effect of delaying, deferring or discouraging another party from acquiring control of us.
Delaware Law. We are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. In general, those provisions prohibit a public Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:
 
 	•	 	the transaction is approved by the board of directors before the date the interested stockholder attained that status;	
 
 	•	 	upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or	
 
 	•	 	on or after the date the business combination is approved by the board of directors and authorized at a meeting of stockholders, and not by written consent, by at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.	
In general, Section 203 defines a business combination to include the following:
 
 	•	 	any merger or consolidation involving the corporation and the interested stockholder;	
 
 	•	 	any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;	
 
 	•	 	subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;	
 
 	•	 	any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or	
 
 	•	 	the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.	
In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by any such entity or person.

Table of Contents
A Delaware corporation may opt out of this provision by express provision in its original certificate of incorporation or by amendment to its certificate of incorporation or bylaws approved by its stockholders. However, we have not opted out of, and do not currently intend to opt out of, this provision. The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us.
Charter and Bylaws. Our certificate of incorporation and bylaws contain certain provisions that are intended to enhance the likelihood of continuity and stability in the composition of the board of directors and which may have the effect of delaying, deferring or preventing a future takeover or change in control of our company unless such takeover or change in control is approved by the board of directors, including:
Authorized but Unissued Preferred Stock. Our board of directors is authorized to issue, without stockholder approval, preferred stock with such terms as the board of directors may determine.
Calling Special Stockholder Meetings. Our bylaws provide that special meetings of our stockholders may be called only pursuant to the request of our board of directors, by the chairman of our board of directors, by our chief executive officer or by the holders of at least 25% of the voting power of all then outstanding shares of our common stock. In addition, stockholders may not fill vacancies on the board of directors and may not act by written consent.
Advanced Notice Procedures. Stockholders must timely provide advance notice, with specific requirements as to form and content, of nominations of directors or the proposal of business to be voted on at an annual meeting.
Board of Directors. Our bylaws provide that our board of directors will be elected annually by the stockholders in accordance with the certificate of incorporation and bylaws at the annual meeting. Each director shall serve for a one-year term or until a successor is duly elected or qualified, or until such director’s earlier death, resignation, disqualification or removal. The bylaws provide that the number of directors will initially be seven and thereafter may be fixed by the board of directors in accordance with the certificate of incorporation and bylaws.
Other Board of Director Requirements. Our authorized number of directors may be changed only by resolution of the board of directors and all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum. In addition, directors may only be removed for cause and then only by a vote of holders of a majority of the shares entitled to vote at an election of directors.
Conflicts of Interest. Delaware law permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors or stockholders. Our certificate of incorporation renounces any interest or expectancy that we have in, or right to be offered an opportunity to participate in, specified business opportunities. Our certificate of incorporation provides that none of our non-employee directors, non-employee 5% or greater stockholders or their affiliates will have any duty to refrain from engaging in a corporate opportunity in the same or similar lines of business in which we or our affiliates now engage or propose to engage. In addition, in the event that any such director, stockholder or affiliate acquires knowledge of a potential transaction or other business opportunity which may be a corporate opportunity for us or our affiliates, such person will have no duty to communicate or offer such transaction or business opportunity to us and may take any

Table of Contents
such opportunity for themselves or offer it to another person or entity. Our certificate of incorporation does not renounce our interest in any business opportunity that is expressly offered to a director solely in his or her capacity as our director.
Director and Officer Indemnification. We will indemnify officers and directors against losses that they may incur in investigations and legal proceedings resulting from their services to us, which may include services in connection with takeover defense measures.
Supermajority Voting Requirements. In addition to the vote of the holders of any class or series of stock required by law, the bylaws or the certificate of incorporation, the affirmative vote of the holders of at least 66 2/3% in voting power of all shares of our stock entitled to vote generally in the election of directors, voting together as a single class, is required in order for our stockholders to alter, amend or repeal the provisions of our bylaws or amend or repeal of certain provisions of our certificate of incorporation including the following:
 
 	•	 	the resignation and removal of directors;	
 
 	•	 	the provisions regarding competition and corporate opportunities;	
 
 	•	 	the provisions regarding stockholder action by written consent;	
 
 	•	 	the provisions regarding calling special meetings of stockholders;	
 
 	•	 	filling vacancies on our board and newly created directorships;	
 
 	•	 	the advance notice requirements for stockholder proposals and director nominations; and	
 
 	•	 	indemnification provisions.	
In addition, our certificate of incorporation grants our board the authority to amend and repeal our bylaws without a stockholder vote in any manner not inconsistent with the laws of the State of Delaware or our certificate of incorporation.
Limitations on Liability and Indemnification of Officers and Directors
The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties. Our certificate of incorporation includes a provision that eliminates the personal liability of directors for monetary damages for actions taken as a director, except to the extent such exemption from liability is not permitted by the DGCL.
Our certificate of incorporation and bylaws provide that we must indemnify our directors and officers to the fullest extent authorized by the DGCL. We are also expressly obligated to advance certain expenses (including attorneys’ fees and disbursements and court costs) and carry directors’ and officers’ insurance providing indemnification for our directors, officers and certain employees for some liabilities. We believe that these indemnification provisions and insurance are useful to attract and retain qualified directors and executive officers.

Table of Contents
The limitation of liability and indemnification provisions in our certificate of incorporation and bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.
Listing
Our common stock is listed on the NYSE under the symbol “MX.”

PLAN OF DISTRIBUTION
We are registering 4,088,978 Common Shares for possible sale by the selling stockholders. Unless the context otherwise requires, as used in this prospectus, “selling stockholders” includes the selling stockholders named in the table above and donees, pledgees, transferees or other successors-in-interest selling Common Shares received from the selling stockholders as a gift, pledge, partnership distribution or other transfer after the date of this prospectus.
The selling stockholders may offer and sell all or a portion of the Common Shares covered by this prospectus from time to time, in one or more or any combination of the following transactions:
 
 	•	 	in underwritten transactions;	
 
 	•	 	on the NYSE, in the over-the-counter market or on any other national securities exchange on which our shares are then listed or traded;	
 
 	•	 	in privately negotiated transactions;	
 
 	•	 	in a block trade in which a broker-dealer will attempt to sell the offered shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;	
 
 	•	 	through purchases by a broker-dealer as principal and resale by the broker-dealer for its account pursuant to this prospectus;	
 
 	•	 	through the distribution of the Common Shares by any selling stockholder holder to its partners, members or stockholders;	
 
 	•	 	in ordinary brokerage transactions and transactions in which the broker solicits purchasers;	
 
 	•	 	through the writing or settlement of options (including put or call options), whether the options are listed on an options exchange or otherwise;	
 
 	•	 	a combination of any such methods of sale; and	
 
 	•	 	any other method permitted pursuant to applicable law.	
The selling stockholders may sell the Common Shares at prices then prevailing or related to the then current market price or at negotiated prices. The offering price of the Common Shares from time to time will be determined by the selling stockholders and, at the time of the determination, may be higher or lower than the market price of our common stock on NYSE or any other exchange or market.
The Common Shares may be sold directly or through broker-dealers acting as principal or agent, or pursuant to a distribution by one or more underwriters on a firm commitment or best-efforts basis. The selling stockholders may also enter into hedging transactions with broker-dealers. In connection with such transactions, broker-dealers of other financial institutions may engage in short sales of our Common Shares in the course of hedging the positions they assume

with the selling stockholders. The selling stockholders may also enter into options or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of Common Shares offered by this prospectus, which Common Shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). In connection with an underwritten offering, underwriters or agents may receive compensation in the form of discounts, concessions or commissions from the selling stockholders or from purchasers of the offered Common Shares for whom they may act as agents. In addition, underwriters may sell the Common Shares to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. The selling stockholders and any underwriters, dealers or agents participating in a distribution of the Common Shares may be deemed to be “underwriters” within the meaning of the Securities Act, and any profit on the sale of the Common Shares by the selling stockholders and any commissions received by broker-dealers may be deemed to be underwriting commissions under the Securities Act.
The selling stockholders may agree to indemnify an underwriter, broker-dealer or agent against certain liabilities related to the selling of the Common Shares, including liabilities arising under the Securities Act. Under the Registration Rights Agreement, we have agreed to indemnify the selling stockholders against certain liabilities related to the sale of the Common Shares, including certain liabilities arising under the Securities Act. Under the Registration Rights Agreement, we have also agreed to pay the costs, expenses and fees of registering the Common Shares, including the fees, charges and disbursements of one firm of counsel to the selling stockholders; however, the selling stockholders will pay any underwriting fees, discounts, selling commissions and stock transfer taxes relating to the registration and sale of the Common Shares in any underwritten offering.
Upon our notification by the selling stockholders that any material arrangement has been entered into with an underwriter or broker-dealer for the sale of Common Shares through a block trade, special offering, exchange distribution, secondary distribution or a purchase by an underwriter or broker-dealer, we will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, disclosing certain material information, including:
 
 	•	 	the name of the selling stockholders;	
 
 	•	 	the number of Common Shares being offered;	
 
 	•	 	the terms of the offering;	
 
 	•	 	the names of the participating underwriters, broker-dealers or agents;	
 
 	•	 	any fees, discounts, selling commissions or other compensation paid to underwriters or broker-dealers and any fees, discounts, selling commissions or concessions allowed or reallowed or paid by any underwriters to dealers;	
 
 	•	 	the public offering price; and	
 
 	•	 	other material terms of the offering.	
 
14

Table of Contents
In addition, upon being notified by the selling stockholders that a donee, pledgee, transferee, other successor-in-interest intends to sell more than 500 Common Shares, we will, to the extent required, promptly file a supplement to this prospectus to name specifically such person as a selling stockholder.
The selling stockholders are subject to the applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M. This regulation may limit the timing of purchases and sales of any of the Common Shares offered in this prospectus by the selling stockholders. The anti-manipulation rules under the Exchange Act may apply to sales of the Common Shares in the market and to the activities of the selling stockholders and their affiliates. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of the Common Shares to engage in market-making activities for the particular securities being distributed for a period of up to five business days before the distribution. The restrictions may affect the marketability of the Common Shares and the ability of any person or entity to engage in market-making activities for the Common Shares.
In compliance with the guidelines of the Financial Industry Regulatory Authority (“FINRA”), the aggregate maximum discount, commission, agency fees, or other items constituting underwriting compensation to be received by any FINRA member or independent broker dealer will not exceed 8% of any offering pursuant to this prospectus and any applicable prospectus supplement.
To the extent required, this prospectus may be amended and/or supplemented from time to time to describe a specific plan of distribution. Instead of selling the Common Shares under this prospectus, the selling stockholders may sell the Common Shares in compliance with the provisions of Rule 144 under the Securities Act, if available, or pursuant to other available exemptions from the registration requirements of the Securities Act.

INFORMATION NOT REQUIRED IN PROSPECTUS
Item 14. Other Expenses of Issuance and Distribution.
The following table sets forth the costs and expenses to be paid by us in connection with the sale of the shares of common stock being registered hereby. All amounts are estimates except for the Securities and Exchange Commission, or SEC, registration fee.

Securities and Exchange Commission registration fee	  	$	3,934	 	
Accounting fees and expenses	  	$	25,000	 	
Legal fees and expenses	  	$	200,000	 	
Printing and miscellaneous expenses	  	$	10,000	 	
 	  	 	 	 	
Total(1)	  	$	238,934	 	

(1)	Does not include any fees or expenses in connection with any subsequent underwritten offering and any prospectus supplements prepared in connection therewith. Such expenses are not presently known and cannot be estimated.	
Item 15. Indemnification of Directors and Officers.
Section 145 of the General Corporation Law of the State of Delaware, or DGCL, provides that a corporation may indemnify directors and officers as well as employees, agents, and certain other individuals against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party or who is threatened to be made a party by reason of such person being or having been a director, officer, employee of or agent to the registrant to the extent and under the circumstances set forth therein. The statute provides that it is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.
As permitted by the DGCL, our certificate of incorporation includes a provision that eliminates the personal liability of our directors for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability is not permitted by DGCL.
As permitted by the DGCL, our bylaws provide that (1) we are required to indemnify our directors and officers to the fullest extent permitted by the DGCL, subject to certain exceptions; (2) we are permitted to indemnify our other employees and agents to the extent that we indemnify our officers and directors; (3) we are required to advance expenses, as incurred, to our directors and officers in connection with any legal proceeding, subject to certain exceptions; and (4) the rights conferred in our bylaws are not exclusive.
We have entered into indemnification agreements with our directors and officers. The indemnification agreements provide for indemnification and advancement of expenses to our directors and officers under certain circumstances for acts or omissions to the extent permissible under Delaware law. We also obtained directors’ and officers’ liability insurance, which insures against liabilities that our directors or officers may incur in such capacities. We believe that our charter and bylaw provisions are necessary to attract and retain qualified persons as directors and officers.

Item 17. Undertakings.
The undersigned registrant hereby undertakes:
(a)(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
provided, however, that paragraphs (a)(1)(i), (ii), and (iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 (15 U.S.C. 78m or 78o(d)) that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
(i) If the registrant is relying on Rule 430B,
(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the
 
II-3

Table of Contents
securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
(ii) if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.
(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:
We have acted as special counsel to MagnaChip Semiconductor Corporation, a Delaware corporation (the “Company”), in connection with the Registration Statement on Form S-3, as amended (the “Registration Statement”), of the Company, filed with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the “Act”), and the rules and regulations thereunder (the “Rules”). You have asked us to furnish our opinion as to the legality of the securities being registered under the Registration Statement. The Registration Statement relates to the registration under the Act of up to 4,088,978 shares (the “Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”), that may be offered by certain stockholders of the Company.

In connection with the furnishing of this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents:
 
 	1.	the Registration Statement;	
 
 	2.	the Second Amended Chapter 11 Plan of Reorganization Proposed by the Official Committee of Unsecured Creditors of MagnaChip Semiconductor Finance Company, et al., dated as of September 24, 2009; and	
 
 	3.	Findings of Fact, Conclusions of Law, and Order Confirming Second Amended Chapter 11 Plan of Reorganization Proposed by the Official Committee of Unsecured Creditors of MagnaChip Semiconductor Finance Company, et al., dated as of September 25, 2009.	
In addition, we have examined (i) such corporate records of the Company as we have considered appropriate, including a copy of the certificate of incorporation, as amended, and by-laws, as amended, of the Company, certified by the Company as in effect on the date of this letter, and copies of resolutions of the board of directors of the Company relating to the issuance of the Shares, certified by the Company and (ii) such other certificates, agreements and documents as we deemed relevant and necessary as a basis for the opinions expressed below.

Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that the Shares have been duly authorized by all necessary corporate action on the part of the Company and are validly issued, fully paid and non-assessable.
