Description of Securities of Mirion Technologies, Inc

The following description sets forth certain material terms and provisions of the securities of Mirion Technologies, Inc. that are registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The following summary of the material terms of our securities is not intended to be a complete summary of the rights and preferences of such securities. The descriptions below are qualified by reference to the actual text of our certificate of incorporation (the “Charter”) and our bylaws (the “Bylaws”), which are filed as exhibits to our Annual Report on Form 10-K filed on February 28, 2022 (the “Annual Report”). We advise you to read our Charter and Bylaws in their entirety for a complete description of the rights and preferences of our securities. Unless the context otherwise indicates or requires, references to “the Company,” “we,” “us,” “our” and “Mirion” refer to Mirion Technologies, Inc., a Delaware corporation, and its consolidated subsidiaries.

Our authorized capital stock consists of 700,000,000 shares of capital stock, par value $0.0001 per share, of which:

500,000,000 shares are designated as Class A common stock (as defined below);

100,000,000 shares are designated as Class B common stock (as defined below); and

100,000,000 shares are designated as preferred stock.

Our board of directors (the “Board”) is authorized, without stockholder approval, except as required by the listing standards of the New York Stock Exchange (the “NYSE”), to issue additional shares of capital stock within these limits.

As of February 22, 2022, we had approximately 199,523,292 shares of Class A common stock, par value $0.0001 per share, of the Company (the “Class A common stock”) outstanding and approximately 8,560,540 shares of Class B common stock outstanding (the “Class B common stock” and, together with the Class A common stock, the “common stock”) and no shares of preferred stock outstanding. In addition, as of February 22, 2022, there are warrants to purchase 27,249,979 shares of Class A common stock outstanding, consisting of warrants to purchase 18,749,979 shares of Class A commons stock sold to the public in our initial public offering (the “public warrants”) and warrants to purchase 8,500,000 shares of Class A common stock issued in a private placement to GS Sponsor II LLC, a Delaware limited liability company (the “Sponsor”) (the “private placement warrants” and, together with the public warrants, the “warrants”).

Holders of shares of our Class A common stock are entitled to one vote for each share held of record on all matters on which stockholders are entitled to vote generally, including the election or removal of directors. The holders of our Class A common stock do not have cumulative voting rights in the election of directors.

Holders of shares of our Class A common stock are entitled to receive dividends when and if declared by our Board out of funds legally available therefor, subject to any statutory or contractual restrictions on the payment of dividends and to any restrictions on the payment of dividends imposed by the terms of any outstanding preferred stock.

Upon our liquidation, dissolution or winding up and after payment in full of all amounts required to be paid to creditors and to the holders of preferred stock having liquidation preferences, if any, the holders of shares of our Class A common stock will be entitled to receive pro rata our remaining assets available for distribution.

Holders of shares of our Class B common stock are entitled to one vote for each share held of record on all matters on which stockholders are entitled to vote generally, including the election or removal of directors. If at any time the ratio at which shares of IntermediateCo (as defined below) Class B common stock, par value $0.0001 per share (“IntermediateCo Class B common stock”) are redeemable or

exchangeable for shares of our Class A common stock changes from one-for-one as described under “Part III, Item 13—Certain Relationships and Related Transactions, and Director Independence—IntermediateCo Charter” of our Annual Report, the number of votes to which our Class B common stockholders are entitled will be adjusted accordingly. The holders of our Class B common stock do not have cumulative voting rights in the election of directors.

Except for transfers to us pursuant to the certificate of incorporation of IntermediateCo (the “IntermediateCo Charter”) or to certain permitted transferees set forth in our Charter, the shares of our Class B common stock and corresponding shares of IntermediateCo Class B common stock may not be sold, transferred or otherwise disposed of.

Holders of shares of our Class B common stock are not entitled to economic interests in us or to receive dividends or to receive a distribution upon our liquidation or winding up. However, if Mirion IntermediateCo, Inc., a Delaware corporation (“IntermediateCo”) makes distributions to us other than solely with respect to our Class A common stock, the holders of IntermediateCo Class B common stock will be entitled to receive distributions pro rata in accordance with the percentages of their respective shares of IntermediateCo Class B common stock. See “Part III, Item 13—Certain Relationships and Related Transactions, and Director Independence—IntermediateCo Charter” of our Annual Report.

Except as otherwise required in our Charter or by applicable law, the holders of our common stock will vote together as a single class on all matters on which stockholders generally are entitled to vote.

The holders of the outstanding shares of our Class A common stock shall be entitled to vote separately upon any amendment to our Charter (including by merger, consolidation, reorganization or similar event) that would alter or change the powers, preferences or special rights of our Class A common stock in a manner that is materially and disproportionately adverse as compared to any alteration or change to our Class B common stock.

The holders of the outstanding shares of our Class B common stock shall be entitled to vote separately upon any amendment to our Charter (including by merger, consolidation, reorganization or similar event) that would alter or change the powers, preferences or special rights of our Class B common stock in a manner that is materially and disproportionately adverse as compared to any alteration or change to our Class A common stock, subject to certain exceptions set forth in our Charter.

Under the IntermediateCo Charter, the holders of IntermediateCo Class B common stock have the right (subject to the terms of the IntermediateCo Charter) to require IntermediateCo to redeem all or a portion of their shares of IntermediateCo Class B common stock for, at our election, (1) newly issued shares of our Class A common stock on a one-for-one basis or (2) a cash payment equal to the arithmetic average of the closing stock prices for a share of our Class A common stock for each of three (3) consecutive full trading days ending on and including the last full trading day immediately prior to the date of redemption (subject to customary adjustments, including for stock splits, stock dividends and reclassifications) in accordance with the terms of the IntermediateCo Charter. Additionally, in the event of a redemption request by a holder of IntermediateCo Class B common stock, we may, at our election, effect a direct exchange of cash or our Class A common stock for IntermediateCo Class B common stock in lieu of such a redemption. Shares of our Class B common stock will be canceled on a one-for-one basis if we, following a redemption request of a holder of IntermediateCo Class B common stock, redeem or exchange IntermediateCo Class B common stock of such holder of IntermediateCo Class B common stock pursuant to the terms of the IntermediateCo Charter. See “Part III, Item 13—Certain Relationships and Related Transactions, and Director Independence—IntermediateCo Charter” of our Annual Report.

All shares of our Class A common stock and Class B common stock (our “common stock”) that are outstanding are fully paid and non-assessable. Our common stock is not subject to calls or assessments by us. The rights, powers and privileges of our common stock is subject to those of the holders of any shares of our preferred stock or any other series or class of stock we may authorize and issue in the future.

Pursuant to our Charter, our Board has the authority, without further action by the stockholders, to issue from time to time shares of preferred stock in one or more series. Our Board may designate the rights, preferences, privileges and restrictions of our preferred stock, including dividend rights, conversion rights, voting rights, redemption rights, liquidation preference, sinking fund terms, and the number of shares constituting any series or the designation of any series.

The issuance of our preferred stock could have the effect of restricting dividends on our common stock, diluting the voting power of our common stock, impairing the liquidation rights of our common stock or delaying, deterring, or preventing a change in control. Such issuance could have the effect of decreasing the market price of our common stock. There are currently no plans to issue any shares of our preferred stock.

Each whole warrant entitles the registered holder to purchase one share of our Class A common stock at a price of $11.50 per share, except as described below. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of shares of Class A common stock. This means only a whole warrant may be exercised at a given time by a warrant holder. The warrants will expire five years after the completion of our initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00. Once the warrants become exercisable, we may redeem the outstanding warrants (except as described herein with respect to the private placement warrants):

•in whole and not in part;

•at a price of $0.01 per warrant;

•upon a minimum of 30 days’ prior written notice of redemption, or the 30-day redemption period, to each warrant holder; and

•if, and only if, the last reported sale price of our Class A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which we send the notice of redemption to the warrant holders.

We have established the $18.00 per share (as adjusted) redemption criteria discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the warrants, each warrant holder will be entitled to exercise its warrant prior to the scheduled redemption date. However, the price of our Class A common stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) as well as the $11.50 warrant exercise price after the redemption notice is issued.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00. We may redeem the outstanding warrants (except as described herein with respect to the private placement warrants):

•in whole and not in part;

•at a price of $0.10 per warrant provided that holders will be able to exercise their warrants prior to redemption and receive that number of shares of Class A common stock determined by reference to the table below, based on the redemption date and the “fair market value” of our Class A common stock (as defined below) except as otherwise described below;

•upon a minimum of 30 days’ prior written notice of redemption;

•if, and only if, the last reported sale price of our Class A common stock equals or exceeds $10.00 per share (as adjusted for stock splits, stock dividends, reorganizations,

recapitalizations and the like) on the trading day prior to the date on which we send the notice of redemption to the warrant holders; and

•if, and only if, there is an effective registration statement covering the issuance of the shares of Class A common stock issuable upon exercise of the warrants and a current prospectus relating thereto available throughout the 30-day period after written notice of redemption is given.

The numbers in the table below represent the number of shares of Class A common stock that a warrant holder will receive upon cashless exercise in connection with a redemption by us pursuant to this redemption feature, based on the “fair market value” of our Class A common stock on the corresponding redemption date (assuming holders elect to exercise their warrants and such warrants are not redeemed for $0.10 per warrant), determined based on the average of the last reported sales price for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants, and the number of months that the corresponding redemption date precedes the expiration date of the warrants, each as set forth in the table below.

Pursuant to the warrant agreement, references above to Class A common stock shall include a security other than Class A common stock into which the Class A common stock has been converted or exchanged for in the event we are not the surviving company in our initial business combination. The numbers in the tables below will not be adjusted solely as a result of us not being the surviving entity following our initial business combination.

The stock prices set forth in the column headings of the table below will be adjusted as of any date on which the number of shares issuable upon exercise of a warrant is adjusted as set forth in the first three paragraphs under the heading “—Anti-Dilution Adjustments” below. The adjusted stock prices in the column headings will equal the stock prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the number of shares deliverable upon exercise of a warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a warrant as so adjusted. The number of shares in the table below shall be adjusted in the same manner and at the same time as the number of shares issuable upon exercise of a warrant.

The exact fair market value and redemption date may not be set forth in the table above, in which case, if the fair market value is between two values in the table or the redemption date is between two redemption dates in the table, the number of shares of Class A common stock to be issued for each warrant exercised will be determined by a straight-line interpolation between the number of shares set forth for the higher and lower fair market values and the earlier and later redemption dates, as applicable, based on a 365 or 366-day year, as applicable. For example, if the average last reported sale price of our Class A common stock for the 10 trading days ending on the third trading date prior to the date on which the notice of redemption is sent to the holders of the warrants is $11.00 per share, and at such time there are 57 months until the expiration of the warrants, holders may choose to, in connection with this redemption feature, exercise their warrants for 0.277 shares of Class A common stock for each whole warrant. For an example where the exact fair market value and redemption date are not as set forth in the table above, if the average last reported sale price of our Class A common stock for the 10 trading days ending on the third trading date prior to the date on which the notice of redemption is sent to the holders of the warrants is $13.50 per share, and at such time there are 38 months until the expiration of the warrants, holders may choose to, in connection with this redemption feature, exercise their warrants for 0.298 shares of Class A common stock for each whole warrant. In no event will the warrants be exercisable in connection with this redemption feature for more than 0.365 shares of Class A common stock per warrant. Finally, as reflected in the table above, if the warrants are out of the money and about to expire, they cannot be exercised on a cashless basis in connection with a redemption by us pursuant to this redemption feature, since they will not be exercisable for any shares of Class A common stock.

Any public warrants held by our officers or directors will be subject to this redemption feature, except that such officers and directors shall only receive “fair market value” for such public warrants if they exercise their public warrants in connection with such redemption (“fair market value” for such public warrants held by our officers or directors being defined as the last reported sale price of the public warrants on such redemption date).

This redemption feature is structured to allow for all of the outstanding warrants (other than the private placement warrants) to be redeemed when the Class A common stock is trading at or above $10.00 per share, which may be at a time when the trading price of our Class A common stock is below the exercise price of the warrants. We have established this redemption feature to provide us with the flexibility to redeem the warrants without the warrants having to reach the $18.00 per share threshold set forth above under “—Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00.” Holders choosing to exercise their warrants in connection with a redemption pursuant to this feature will, in effect, receive a number of shares for their warrants based on an option pricing model with a fixed volatility input as of the date of the Company’s initial public offering on June 20, 2020 (the “Public Offering”). This redemption right provides us an additional mechanism by which to redeem all of the outstanding warrants, and therefore have certainty as to our capital structure as the warrants would no longer be outstanding and would have been exercised or redeemed, and we will effectively be required to pay the redemption price to warrant holders if we choose to exercise this redemption right and it will allow us to quickly proceed with a redemption of the warrants if we determine it is in our best interest to do so. As such, we would redeem the warrants in this manner when we believe it is in our best interest to update our capital structure to remove the warrants and pay the redemption price to the warrant holders.

As stated above, we can redeem the warrants when the Class A common stock is trading at a price starting at $10.00, which is below the exercise price of $11.50, because it will provide certainty with respect to our capital structure and cash position while providing warrant holders with the opportunity to exercise their warrants on a cashless basis for the applicable number of shares of Class A common stock. If we choose to redeem the warrants when the Class A common stock is trading at a price below the exercise price of the warrants, this could result in the warrant holders receiving fewer shares of Class A common stock than they would have received if they had chosen to wait to exercise their warrants for shares of Class A common stock if and when shares of Class A common stock were trading at a price higher than the exercise price of $11.50 per share.

No fractional shares of Class A common stock will be issued upon exercise. If, upon exercise, a holder would be entitled to receive a fractional interest in a share, we will round down to the nearest whole number of the number of shares of Class A common stock to be issued to the holder. If, at the time of redemption, the warrants are exercisable for a security other than the shares of Class A common stock pursuant to the warrant agreement, the warrants may be exercised for such security.

Redemption Procedures and Cashless Exercise. If we call the warrants for redemption as described above under “—Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00,” we will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis” (such option, the “Cashless Exercise Option”). In determining whether to require all

holders to exercise their warrants on a “cashless basis,” we will consider, among other factors, our cash position, the number of warrants that are outstanding and the dilutive effect on our stockholders of issuing the maximum number of shares of Class A common stock issuable upon the exercise of our warrants. In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of Class A common stock equal to the lesser of (A) the quotient obtained by dividing (x) the product of the number of shares of Class A common stock underlying the warrants, multiplied by the excess of the “fair market value” over the exercise price of the warrants by (y) the fair market value and (B) 0.365. The “fair market value” shall mean the average last reported sale price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. If our management takes advantage of this Cashless Exercise Option, the notice of redemption will contain the information necessary to calculate the number of shares of Class A common stock to be received upon exercise of the warrants, including the “fair market value” in such case. Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption. We believe this Cashless Exercise Option feature is an attractive option to us if we do not need the cash from the exercise of the warrants after our initial business combination. If we call our warrants for redemption and our management does not take advantage of this Cashless Exercise Option, the Sponsor and its permitted transferees would still be entitled to exercise their private placement warrants for cash or on a cashless basis using the same formula described above that other warrant holders would have been required to use had management taken advantage of this Cashless Exercise Option, as described in more detail below.

A holder of a warrant may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), would beneficially own in excess of 9.8% (or such other amount as a holder may specify) of the shares of Class A common stock outstanding immediately after giving effect to such exercise.

Anti-Dilution Adjustments. If the number of outstanding shares of Class A common stock is increased by a stock dividend payable in shares of Class A common stock, or by a split-up of shares of Class A common stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Class A common stock issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding shares of Class A common stock. A rights offering to all or substantially all holders of Class A common stock entitling holders to purchase shares of Class A common stock at a price less than the fair market value will be deemed a stock dividend of a number of shares of Class A common stock equal to the product of (1) the number of shares of Class A common stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Class A common stock) multiplied by (2) one minus the quotient of (x) the price per share of Class A common stock paid in such rights offering divided by (y) the fair market value. For these purposes (1) if the rights offering is for securities convertible into or exercisable for Class A common stock, in determining the price payable for Class A common stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (2) fair market value means the volume weighted average price of Class A common stock as reported during the ten trading day period ending on the trading day prior to the first date on which the shares of Class A common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if we, at any time while the warrants are outstanding and unexpired, pay to all or substantially all of the holders of Class A common stock a dividend or make a distribution in cash, securities or other assets to the holders of Class A common stock on account of such shares of Class A common stock (or other shares of our capital stock into which the warrants are convertible), other than (a) as described above, (b) certain ordinary cash dividends, (c) to satisfy the redemption rights of the holders of Class A common stock in connection with a proposed initial business combination, or (d) to satisfy the redemption rights of the holders of Class A common stock in connection with a stockholder vote to amend our amended and restated certificate of incorporation (I) to modify the substance or timing of our obligation to allow redemptions in connection with our initial business combination or to redeem 100% of our Class A common stock if we do not complete our initial business combination within 24 months from the closing of this offering or (II) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity, then the warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each share of Class A common stock in respect of such event.

If the number of outstanding shares of our Class A common stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Class A common stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or

similar event, the number of shares of Class A common stock issuable on exercise of each warrant will be decreased in proportion to such decrease in outstanding shares of Class A common stock.

Whenever the number of shares of Class A common stock purchasable upon the exercise of the warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of shares of Class A common stock purchasable upon the exercise of the warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of shares of Class A common stock so purchasable immediately thereafter.

In case of any reclassification or reorganization of the outstanding shares of Class A common stock (other than those described above or that solely affects the par value of such shares of Class A common stock), or in the case of any merger or consolidation of us with or into another corporation (other than a merger or consolidation in which we are the continuing corporation and that does not result in any reclassification or reorganization of our outstanding shares of Class A common stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety in connection with which we are dissolved, the holders of the warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the warrants and in lieu of the shares of our Class A common stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the warrants would have received if such holder had exercised their warrants immediately prior to such event. However, if such holders were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such merger or consolidation, then the kind and amount of securities, cash or other assets for which each warrant will become exercisable will be deemed to be the weighted average of the kind and amount received per share by such holders in such merger or consolidation that affirmatively make such election, and if a tender, exchange or redemption offer has been made to and accepted by such holders under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act) more than 50% of the outstanding shares of Class A common stock, the holder of a warrant will be entitled to receive the highest amount of cash, securities or other property to which such holder would actually have been entitled as a stockholder if such warrant holder had exercised the warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the Class A common stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in the warrant agreement. Additionally, if less than 70% of the consideration receivable by the holders of Class A common stock in such a transaction is payable in the form of Class A common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the warrant properly exercises the warrant within thirty days following public disclosure of such transaction, the warrant exercise price will be reduced as specified in the warrant agreement based on the per share consideration minus Black-Scholes Warrant Value (as defined in the warrant agreement) of the warrant.

The warrants were issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. You should review a copy of the warrant agreement, which is incorporated by reference to our Annual Report for a description of the terms and conditions applicable to the warrants. The warrant agreement provides that (a) the terms of the warrants may be amended without the consent of any holder for the purpose of (i) curing any ambiguity or correct any mistake, including to conform the provisions of the warrant agreement to the description of the terms of the warrants and the warrant agreement set forth in this prospectus, or defective provision or (ii) adding or changing any provisions with respect to matters or questions arising under the warrant agreement as the parties to the warrant agreement may deem necessary or desirable and that the parties deem to not adversely affect the rights of the registered holders of the warrants and (b) all other modifications or amendments require the vote or written consent of at least 50% of the then outstanding public warrants and, solely with respect to any amendment to the terms of the private placement warrants or any provision of the warrant agreement with respect to the private placement warrants, at least 50% of the then outstanding private placement warrants.

The warrant holders do not have the rights or privileges of holders of Class A common stock or any voting rights until they exercise their warrants and receive shares of Class A common stock. After the issuance of shares of Class A common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

The private placement warrants are identical to the public warrants except that, so long as they are held by the Sponsor or its permitted transferees: (1) they will not be redeemable by us; and (2) they may be exercised by the holders on a cashless basis as described below. If the private placement warrants are held by holders other than the Sponsor or its permitted transferees, the private placement warrants will be redeemable by us in all redemption scenarios and exercisable by the holders on the same basis as the warrants included in the units being sold in this offering.

If holders of the private placement warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering warrants for that number of shares of Class A common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A common stock underlying the warrants, multiplied by the excess of the “fair market value” (defined below) over the exercise price of the warrants by (y) the fair market value. The “fair market value” shall mean the average last reported sale price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of exercise is sent to the warrant agent.

Our Charter provides that the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers or other employees to us or our stockholders; (3) any action asserting a claim against us or any current or former director, officer or other employee of us arising out of or pursuant to any provision of the General Corporation Law of the State of Delaware (the “DGCL”), our Charter or our Bylaws; (4) any action to interpret, apply, enforce, or determine the validity of our Charter or our Bylaws; (5) any claim or cause of action as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware; and (6) any other action asserting a claim that is governed by the internal affairs doctrine shall be a state or federal court located within the State of Delaware, in all cases subject to the court having jurisdiction over indispensable parties named as defendants. However, this exclusive forum provision would not apply to suits brought to enforce a duty or liability created by the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act or any claim for which the federal district courts of the United States have exclusive jurisdiction.

In addition, our Charter provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. However, this exclusive forum provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act or any claim for which the federal district courts of the United States have exclusive jurisdiction.

Any person or entity purchasing or otherwise acquiring any interest in our capital stock shall be deemed to have notice of and consented to these provisions and will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder. Although our Board believes these provisions benefit us by providing increased consistency in the application of Delaware law or federal law for the specified types of actions and proceedings, these provisions may have the effect of discouraging lawsuits against us or our directors and officers.

Our Charter provides that we will indemnify our directors to the fullest extent authorized or permitted by applicable law. We have also entered into agreements to indemnify our directors, executive officers and other employees as determined by our Board. Under our Bylaws, we are required to indemnify each of our directors and officers if the basis of the indemnitee’s involvement was by reason of the fact that the indemnitee is or was a director or officer of us or was serving at our request as a director, officer, employee or agent for another entity. We must indemnify our officers and directors against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by the indemnitee in connection with such action, suit or proceeding if the indemnitee acted in good faith and in a manner the indemnitee reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the indemnitee’s conduct was unlawful. Our Charter also requires us to advance expenses incurred by a director or officer in connection with such action, suit or

proceeding to the maximum extent permitted under Delaware law. Any claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce the amount of money available to us.

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 Charter contains provisions renouncing, to the extent permitted by Delaware law, any interest or expectancy that we have in, or right to be offered an opportunity to participate in, specified business opportunities that are from time to time presented to a member of our Board who is not an employee, or any partner, member, director, stockholder, employee or agent of such member. Notwithstanding the foregoing, our Charter does not renounce any interest in a business opportunity that is expressly offered to a director solely in his or her capacity as one of our directors.

Our Charter and our Bylaws contain provisions that could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions and certain provisions of Delaware law, which are summarized below, could discourage takeovers, coercive or otherwise. These provisions are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our Board. Our Board believes that the benefits of increased protection of the potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us.

As discussed above in the section titled “—Preferred Stock,” our Board has the ability to designate and issue preferred stock with voting or other rights or preferences that could deter hostile takeovers or delay changes in our control or management.

Our Charter provides that our stockholders may not act by written consent. This limit on the ability of stockholders to act by written consent may lengthen the amount of time required to take stockholder actions. As a result, the holders of a majority of our common stock would not be able to amend our Charter or our Bylaws or remove directors without holding a meeting of stockholders called in accordance with our Bylaws.

In addition, our Charter provides that special meetings of the stockholders may be called only by the chairman of our Board, our chief executive officer or our Board acting pursuant to a resolution adopted by a majority of our Board. A stockholder may not call a special meeting, which may delay the ability of our stockholders to force consideration of a proposal or for holders controlling a majority of our capital stock to take any action, including the removal of directors.

Our Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our Board or a committee thereof. These advance notice procedures may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed and may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempt to obtain control us.

Our Charter and our Bylaws contain provisions that establish specific procedures for appointing and removing members of our Board. Under our Charter and our Bylaws, vacancies and newly created directorships on our Board may be filled only by a majority of the directors then serving on our Board. We are also subject to certain director nomination agreements that require us to nominate certain directors for election to our Board. See “Part III, Item 13—Certain Relationships and Related Transactions, and Director Independence—Director Nomination Agreements” of our Annual Report.

The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless our Charter provides otherwise. Our Charter does not expressly provide for cumulative voting. Without cumulative voting, a minority stockholder may not be able to gain as many seats on our Board as the stockholder would be able to gain if cumulative voting were permitted. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat on our Board to influence our Board’s decision regarding a takeover.

The affirmative vote of holders of not less than 66 2/3% of the total voting power of all our outstanding securities generally entitled to vote in the election of directors, voting together as a single class will be required to amend, alter, change or repeal specified provisions of our Charter, including those relating to the terms of our common stock, actions by written consent of stockholders, calling of special meetings of stockholders, election and removal of directors, certain indemnification and corporate opportunity matters, and the required vote to amend our Charter and our Bylaws. Our Bylaws may only be amended by our Board or the affirmative vote of holders of not less than 66 2/3% of the total voting power of all of our outstanding securities generally entitled to vote in the election of directors, voting together as a single class. This requirement of a super-majority vote to approve amendments to our Charter and our Bylaws could enable a minority of our stockholders to exercise veto power over any such amendments.

We are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. In general, Section 203 prohibits a publicly held Delaware corporation from engaging, under certain circumstances, in a business combination with an interested stockholder for a period of three years following the date the person became an interested stockholder unless:

•prior to the date of the transaction, our Board approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•upon completion of the transaction that 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, excluding for purposes of determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder, (1) shares owned by persons

•who are directors and also officers and (2) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

•at or subsequent to the date of the transaction, the business combination is approved by our Board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

Generally, a business combination includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. Our Board expects the existence of this provision to have an anti-takeover effect with respect to transactions our Board does not approve in advance.

The provisions of Delaware law and the provisions of our Charter and our Bylaws could have the effect of discouraging others from attempting hostile takeovers and as a consequence, they might also inhibit temporary fluctuations in the market price of our Class A common stock that often result from actual or rumored hostile takeover attempts. These provisions might also have the effect of preventing changes in our management. It is also possible that these provisions could make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests.

Our Class A common stock and warrants are listed on the NYSE under the symbols “MIR” and “MIR WS,” respectively.

The transfer agent for our common stock and warrant agent for the warrants is Continental Stock Transfer & Trust Company.
