RISK FACTORS

Investing in our common stock involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully this prospectus supplement, the accompanying prospectus and any related free writing prospectus and carefully read the risks described under the sections entitled “Risk Factors” in our 2021 10-K and the Subsequent Quarterly Reports, as well as any amendments thereto reflected in subsequent filings with the SEC and in our other filings that are incorporated by reference into this prospectus supplement and the accompanying prospectus in their entirety, together with the other information in the documents incorporated by reference in this prospectus supplement, the accompanying prospectus and any related free writing prospectus. See “Where You Can Find More Information” and “Information Incorporated by Reference.” Additionally, the risks and uncertainties discussed in this prospectus supplement and the accompanying prospectus or in any document incorporated by reference into this prospectus supplement and the accompanying prospectus are not the only risks and uncertainties that we face, and our business, financial condition, prospects, results of operations, cash flow and the market price of our common stock could be materially adversely affected by other matters that are not known to us or that we currently do not consider to be material. If any of these risks actually occurs, our business, reputation, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also carefully read the section entitled “Special Note Regarding Forward-Looking Statements.”

S-5

USE OF PROCEEDS

All of the shares of common stock being offered hereby are being sold by the selling stockholder identified in this prospectus supplement. We will not receive any proceeds from the sale of the common stock by the selling stockholder. We will bear the expenses and fees incurred in connection with the registration of the shares to be sold by the selling stockholder, including registration, listing fees, printers and accounting fees and fees and disbursements of counsel (collectively, the “Registration Expenses”). Other than Registration Expenses, the selling stockholder will bear any selling discounts, commissions, placement agent fees or other similar expenses payable with respect to sales of shares of common stock.

S-6

SELLING STOCKHOLDER

Up to 500,000 shares of our common stock issued to the selling stockholder in connection with the Acquisition are being offered by this prospectus supplement, all of which are being offered for resale for the account of the selling stockholder pursuant to the Registration Rights Agreement. The selling stockholder may from time to time offer and sell pursuant to this prospectus supplement, any, all or none of the shares of our common stock being registered, but is not obligated to do so. The selling stockholder makes no representation that the securities to which this prospectus supplement relates will be offered for sale. For purposes of this prospectus supplement, the selling stockholder includes the selling stockholder set forth in the table below and its permitted transferees, pledgees, assignees, distributees, donees or successors or others who later hold any of the selling stockholder’s interests in the securities covered by this prospectus supplement, in each case subject to the Registration Rights Agreement.

The shares of our common stock being offered by the selling stockholder pursuant to this prospectus supplement are subject to certain lock-up restrictions. See “Plan of Distribution—Lock-up Provisions.”

The table below, as of the date of this prospectus supplement, sets forth certain information known to us, with respect to the beneficial ownership of our shares of common stock held by the selling stockholder. Because the selling stockholder may sell, transfer or otherwise dispose of all, some or none of the shares of our common stock covered by this prospectus supplement, we cannot determine the number of such shares that will be sold, transferred or otherwise disposed of by the selling stockholder, or the amount or percentage of shares of our common stock that will be held by the selling stockholder upon termination of any particular offering. See the section entitled “Plan of Distribution.” In addition, the selling stockholder may sell, transfer or otherwise dispose of, at any time and from time to time, the securities it holds in transactions exempt from the registration requirements of the Securities Act after the date of this prospectus supplement. Therefore, for purposes of the table below, we have assumed that the selling stockholder will sell all of its shares of common stock covered by this prospectus supplement.

For the purposes of the table below, the percentage of shares beneficially owned is determined in accordance with the rules and regulations of the SEC, including Rule 13d-3 under the Exchange Act. These rules generally provide that a person is the beneficial owner of securities if such person has or shares the power to vote or direct the voting thereof, or to dispose or direct the disposition thereof or has the right to acquire such powers within 60 days. We have based percentage of beneficial ownership prior to this offering on 245,529,851 shares of common stock outstanding as of October 21, 2022.

All information with respect to common stock ownership of the selling stockholder has been furnished by or on behalf of the selling stockholder. We believe, based on information supplied by the selling stockholder, that except as may otherwise be indicated in the table below, the selling stockholder has sole voting and dispositive power with respect to the securities reported as beneficially owned by it.

PLAN OF DISTRIBUTION

The selling stockholder may, from time to time, sell any or all of the shares of common stock beneficially owned by it and offered hereby. The selling stockholder will act independently of us in making decisions with respect to the timing, manner and size of each sale. We will not receive any of the proceeds from the sale by the selling stockholder of the shares of common stock.

The selling stockholder, which, as used herein, includes any of its donees, pledgees, distributees, assignees, transferees and successors-in-interest selling shares of common stock received after the date of this prospectus supplement from the selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of the securities covered hereby on the principal trading market for the common stock or any other stock exchange, market or trading facility on which our common stock is traded or in private transactions. These dispositions may be at market prices prevailing at the time of sale, at prices related to such market prices, at varying prices determined at the time of sale, at fixed prices or at negotiated prices. The selling stockholder may use any one or more of the following methods when disposing of its securities:

•

on NYSE, in the over-the-counter market or on any other national securities exchange on which our securities are listed or traded;

•

through underwriters, brokers or dealers or agents for resale to the public or to institutional investors at various times;

•

to or through underwriters or dealers in one or more underwritten offerings or pursuant to other underwritten transactions on a firm commitment or best-efforts basis;

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•

block trades in which the broker-dealer will attempt to sell the common stock as agent, but may purchase and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•

an exchange distribution in accordance with the rules of the applicable exchange;

•

through trading plans entered into by the selling stockholder pursuant to Rule 10b5-1 under the Exchange Act that are in place at the time of an offering pursuant to this prospectus supplement and any applicable prospectus supplement hereto that provide for periodic sales of securities on the basis of parameters described in such trading plans;

•

directly to one or more purchasers, including through a specific bidding, auction or other process or in privately negotiated transactions;

•

settlement of short sales;

•

distribution to employees, members, limited partners or equityholders of the selling stockholder;

•

in transactions through broker-dealers that agree with the selling stockholder to sell a specified number of such shares at a stipulated price per share;

•

through the writing or settlement of options (including put or call options) or other hedging transactions, whether through an options exchange or otherwise;

•

by pledge to secured debts and other obligations;

•

delayed delivery arrangements;

•

in “at the market” offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

S-8

•

a combination of any such methods of sale; and

•

any other method permitted by applicable law.

The selling stockholder may, from time to time, pledge or grant a security interest in some or all of the securities it owns and, if it defaults in the performance of its secured obligations, the pledgees or secured parties may offer and sell the securities, from time to time, under this prospectus supplement, or under an amendment to this prospectus supplement amending the list of selling stockholders to include any donee, pledgee, transferee or other successors-in-interest as selling stockholders under this prospectus supplement. The selling stockholder also may transfer the securities in other circumstances, in which case the donees, transferees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus supplement. Upon being notified by the selling stockholder, in accordance with the Registration Rights Agreement, that a donee, pledgee, transferee, or other successor-in-interest intends to sell our securities, we will, to the extent required, promptly file a prospectus supplement or, if appropriate, a post-effective amendment, to name specifically such person as a selling stockholder.

In addition, the selling stockholder may elect to make a pro rata in-kind distribution of shares of our common stock to its members, partners or stockholders pursuant to the registration statement of which this prospectus supplement forms a part by delivering a prospectus supplement. To the extent that such members, partners or stockholders are not affiliates of ours, such members, partners or stockholders would thereby receive freely tradeable shares of our common stock pursuant to the distribution through a registration statement.

To the extent required, with respect to a particular offering of the securities held by the selling stockholder, the specific securities to be offered and sold, the name of the selling stockholder, the respective purchase prices and public offering prices, the proceeds to be received from the sale (if any) and other material terms of the offering, the settlement of short sales entered into after the date of this prospectus supplement, the names of any participating agents, broker-dealers or underwriters and any applicable commissions or discounts, concessions and other items constituting compensation from the selling stockholder will be set forth in a prospectus supplement or, if appropriate, a post-effective amendment.

The aggregate proceeds to the selling stockholder from the sale of the securities offered hereby will be the purchase price of such securities less discounts or commissions, if any. The selling stockholder reserves the right to accept and, together with its agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents.

Instead of selling the securities pursuant to this prospectus supplement, the selling stockholder may sell the securities 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. The selling stockholder has the sole and absolute discretion not to accept any purchase offer or make any sale of securities if it deems the purchase price to be unsatisfactory at any particular time.

The selling stockholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus supplement to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, that the third parties may sell securities covered by this prospectus supplement and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by any selling stockholder or borrowed from any selling stockholder or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from any selling stockholder in settlement of those derivatives to close out any related open borrowings of stock.

The selling stockholder may also pledge securities to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution, may affect sales of the pledged securities pursuant to this prospectus supplement (as supplemented or amended to reflect such transaction).

S-9

In order to facilitate the offering of the securities, any underwriters or agents, as the case may be, involved in the offering of such securities may engage in transactions that stabilize, maintain or otherwise affect the price of our securities. Specifically, the underwriters or agents, as the case may be, may over allot in connection with the offering, creating a short position in our securities for their own account. In addition, to cover overallotments or to stabilize the price of our securities, the underwriter or agents, as the case may be, may bid for, and purchase, such securities in the open market. Finally, in any offering of securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allotted to an underwriter or a broker-dealer for distributing such securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. The underwriters or agents, as the case may be, are not required to engage in these activities, and may end any of these activities at any time.

The selling stockholder may solicit offers to purchase shares directly from, and it may sell such shares directly to, institutional investors or others. In this case, no underwriters or agents would be involved. The terms of any of those sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement, if any.

It is possible that one or more underwriters may make a market in our securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for our securities.

The selling stockholder may authorize underwriters, broker-dealers or agents to solicit offers by certain purchasers to purchase the securities at the public offering price set forth in a prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we or the selling stockholder pay for solicitation of these contracts.

In effecting sales, broker-dealers or agents engaged by the selling stockholder may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the selling stockholder (or, if any broker-dealer acts as agent for the purchaser of common stock, from the purchaser) in amounts to be negotiated immediately prior to the sale. In compliance with the guidelines of the Financial Industry Regulatory Authority (“FINRA”), the aggregate maximum discount, commission, fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed eight percent (8%) of the gross proceeds of any offering pursuant to this prospectus supplement and any applicable prospectus supplement.

If at the time of any offering made under this prospectus supplement a member of FINRA participating in the offering has a “conflict of interest” as defined in FINRA Rule 5121 (“Rule 5121”), that offering will be conducted in accordance with the relevant provisions of Rule 5121.

To our knowledge, there are currently no plans, arrangements, or understandings between the selling stockholder and any broker-dealer or agent regarding the sale of the shares by the selling stockholder. Upon our notification by the selling stockholder that any material arrangement has been entered into with an underwriter or broker-dealer for the sale of securities through a block trade, special offering, exchange distribution, secondary distribution or a purchase by an underwriter or broker-dealer, we will file, if required by applicable law or regulation, a supplement to this prospectus pursuant to Rule 424(b) under the Securities Act disclosing certain material information relating to such underwriter or broker-dealer and such offering.

Underwriters, broker-dealers or agents may facilitate the marketing of an offering online directly or through one of their affiliates. In those cases, prospective investors may view offering terms and a prospectus online and, depending upon the particular underwriter, broker-dealer or agent, place orders online or through their financial advisors.

S-10

In connection with the sale of the common stock or interests therein, the selling stockholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholder may also sell common stock short and deliver these shares to close out its short positions, or loan or pledge the securities to broker-dealers that in turn may sell these shares. The selling stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of the securities offered by this prospectus supplement, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus supplement.

In offering the securities covered by this prospectus supplement, the selling stockholder and any underwriters, broker-dealers or agents who execute sales for the selling stockholder or otherwise participate in the sale of the securities herein may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any discounts, commissions or concessions received by such underwriters, broker-dealers or agents and any profit they earn on any resale of such securities may be deemed to be underwriting commissions or discounts under the Securities Act.

We are required to pay certain fees and expenses incurred by us incident to the registration of the common stock.

The underwriters, broker-dealers and agents may engage in transactions with us or the selling stockholder, or perform services for us or the selling stockholder, in the ordinary course of business.

In order to comply with the securities laws of some states, if applicable, the securities must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states, the securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from registration or qualification requirements is available and is complied with. A selling stockholder who is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including anti-manipulation rules of Regulation M, which may apply to sales of securities in the market and to the activities of the selling stockholder and its affiliates, such as limiting the timing of purchases and sales of the common stock by the selling stockholder or any other person. We will make copies of this prospectus supplement and the accompanying prospectus (as it may be supplemented or amended from time to time) available to the selling stockholder and have informed it of the need to deliver a copy of this prospectus supplement and the accompanying prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Lock-up Provisions

In connection with the transactions contemplated by the definitive agreement for the Acquisition and related documents, including the Registration Rights Agreement, CIG agreed to certain lock-up provisions which require CIG to continue to own (subject to customary exceptions) the shares of common stock being offered for resale pursuant to this prospectus supplement from the issue date until November 1, 2022.

OUR COMPANY

NexTier Oilfield Solutions Inc. is a predominately U.S. land focused oilfield service company, with a diverse set of well completion and production services across a variety of active and demanding basins. We provide our services through our operating subsidiaries to exploration and production customers. Our integrated solutions approach is focused on delivering efficiency, and our ongoing commitment to innovation helps our customers capitalize on technological advancements. NexTier is differentiated through four points of distinction, including safety performance, efficiency, partnership and innovation.

We were formed under the name Keane Group, Inc. as a Delaware corporation on October 13, 2016, to be a holding corporation as part of an organizational restructuring of Keane Group Holdings, LLC, which was formed March 1, 2011, and its subsidiaries, for the purpose of facilitating the initial public offering of shares of common stock of the Company in 2017. On January 25, 2017, we consummated an initial public offering (“IPO”). To effectuate the IPO, we completed a series of transactions reorganizing our business, resulting in the Company being a holding company with no material assets other than its ownership of Keane Group. In connection with the restructuring, the Keane Group entities became wholly owned subsidiaries of the Company.

In continuation of our growth through acquisition strategy, which since 2013 has notably resulted in the growth of the location and scale of our operational footprint, expansion of our customer base, addition of wireline operations, increase in our pumping capacity and expansion of our hydraulic fracturing operations by more than an additional 1,040,000 hydraulic horsepower, on October 31, 2019, we completed a merger transaction (the “C&J Merger”) with C&J Energy Services, Inc., then a publicly traded Delaware corporation. Pursuant to this transaction, C&J was ultimately merged with and into one of our wholly owned subsidiaries, with our subsidiary continuing as the surviving entity. On the effective date of the C&J Merger, we changed our name to “NexTier Oilfield Solutions Inc.”

We provide services largely, consisting of:

•

Completion Services, which is comprised of: (1) fracturing services; (2) wireline and pumping services; and (3) completion support services, which includes our research and technology department; and

•

Well Construction and Intervention Services, which is comprised of: (1) cementing services and (2) coiled tubing services.

We provide our services in several of the most active basins in the United States, including the Permian, the Marcellus Shale/Utica, the Eagle Ford and the Bakken/Rockies. The high density of our operations in the basins in which we are most active provides us the opportunity to leverage our fixed costs and to quickly respond with what we believe are highly efficient, integrated solutions that are best suited to address customer requirements. We provide our services in conjunction with onshore well development, in addition to stimulation operations on existing wells, to exploration and production customers with some of the highest quality and safety standards in the industry. We believe our proven capabilities enable us to deliver cost-effective solutions for increasingly complex and technically demanding well completion requirements, which include longer lateral segments, multiple fracturing stages in challenging high-pressure formations and greater proppant intensity.

Our completion services are designed in partnership with our customers to enhance both initial production rates and estimated ultimate recovery from new and existing wells. We utilize our in-house capabilities, including our research and technology department and data control instruments business, to offer a technologically advanced and efficiency focused range of completion techniques. In late 2020, we began evolving our completion service offerings to develop an integrated natural gas treatment and delivery solution. We believe this integration solution will assist our customers to reduce emissions at the wellsite and throughout their operations. This solution is focused on providing gas sourcing, compression, transport, decompression, treatment, and related services for our fracturing operations. We currently expect this additional integrated service to be available to our customers later in 2021.

We seek to deploy our assets with well-capitalized customers that have long-term development programs that enable us to maximize operational efficiencies and the return on our assets. We believe our integrated approach increases efficiencies and provides potential cost savings for our customers, allowing us to broaden our relationships with existing customers and attract new ones.

DESCRIPTION OF CAPITAL STOCK

The following summarizes the most important terms of our common stock and related provisions of the certificate of incorporation and our bylaws. This description also summarizes the principal agreements relating to our common 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 and the agreements referred to below, copies of which are filed as exhibits to the registration statement of which this prospectus forms a part.

General

Our authorized capital stock consists of 500,000,000 shares of common stock, par value $0.01 per share, and 50,000,000 shares of preferred stock, par value $0.01 per share.

Common Stock

Dividend Rights

Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of our common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.

Voting Rights

Each holder of our common stock is entitled to one vote for each share owned of record on all matters voted upon by stockholders. A majority vote is required for all action to be taken by stockholders, except as otherwise provided for in our certificate of incorporation and bylaws or as required by law, including the election of directors in an election that is determined by our board of directors to be a contested election, which requires a plurality. Our certificate of incorporation provides that our board of directors and, prior to the date that Keane Investor Holdings LLC (“Keane Investor”) and its respective affiliates (as defined in Rule 12b-2 of the Exchange Act), or any person who is an express assignee or designee of Keane Investor’s respective rights under our certificate of incorporation (and such assignee’s or designee’s affiliates) (of these entities, the entity that is the beneficial owner of the largest number of shares is referred to as the “Designated Controlling Stockholder”) ceases to own, in the aggregate, at least 50% of the then-outstanding shares of our common stock (the “50% Trigger Date”), the Designated Controlling Stockholder, are expressly authorized to make, alter or repeal our bylaws and that our stockholders may only amend our bylaws after the 50% Trigger Date with the approval of at least two-thirds of the total voting power of the outstanding shares of our capital stock entitled to vote in any annual election of directors.

From and after such date that the Designated Controlling Stockholder ceases to own, in the aggregate, at least 35% of the then-outstanding shares of our common stock (the “35% Trigger Date”), advance notice requirements for stockholder proposals that can be acted on at stockholder meetings and nominations to our board of directors will be established.

Liquidation Rights

In the event of our liquidation, dissolution or winding-up, the holders of our common stock are entitled to share equally and ratably in our assets, if any, remaining after the payment of all of our debts and liabilities and the liquidation preference of any outstanding preferred stock.

Other Rights

Our common stock has no preemptive rights, no cumulative voting rights and no redemption, sinking fund or conversion provisions.

Preferred Stock

Our board of directors is authorized, by resolution or resolutions, to issue up to 50,000,000 shares of our preferred stock. Our board of directors is authorized, by resolution or resolutions, to provide, out of the unissued shares of our preferred stock, for one or more series of preferred stock and, with respect to each such series, to fix, without further stockholder approval, the designation, powers, preferences and relative, participating, option or other special rights, including voting powers and rights, and the qualifications, limitations or restrictions thereof, of each series of preferred stock pursuant to Section 151 of the Delaware General Corporation Law (the “DGCL”). Our board of directors could authorize the issuance of preferred stock with terms and conditions that could discourage a takeover or other transaction that some holders of our common stock might believe to be in their best interests or in which holders of common stock might receive a premium for their shares over and above market price. We have no current plan to issue any shares of preferred stock.

Composition of our Board of Directors

Our board of directors currently has nine members. The Second Amended and Restated Stockholders’ Agreement, dated as of October 31, 2019, by and among the Company, and Keane Investor (the “Stockholders’ Agreement”) provides that, effective as of the effective time, Keane Investor (or Cerberus Capital Management, L.P. (“Cerberus”), if Cerberus no longer holds its Common Stock through Keane Investor) will have the right to designate (i) two individuals to the Board for as long as Keane Investor or Cerberus, as applicable, has beneficial ownership of at least 12.5% of the outstanding Common Stock and (ii) one individual to the Board for as long as Keane Investor or Cerberus, as applicable, has beneficial ownership of less than 12.5% but at least 7.5% of the outstanding Common Stock. Pursuant to the Stockholders’ Agreement, Keane Investor or Cerberus, as applicable, has customary replacement rights for such designees.

Our certificate of incorporation provides that our board of directors will consist of not less than seven directors and not more than 15 directors, and that the exact number of directors will be determined by a resolution of our board of directors. Our certificate of incorporation also provides that, prior to the 50% Trigger Date, the Designated Controlling Stockholder may increase or decrease the authorized number of directors on our board of directors. Following the 50% Trigger Date, the authorized number of directors may be increased or decreased only with the approval of at least two-thirds of all of the outstanding shares of our capital stock entitled to vote.

Anti-Takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws

Some provisions of Delaware law and of our certificate of incorporation and bylaws could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our bylaws establish advance notice procedures with respect to stockholder proposals, other than proposals made by or at the direction of our board of directors or, prior to the 35% Trigger Date, by the Designated Controlling Stockholder. Our bylaws also establish advance notice procedures with respect to the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors

or by a committee appointed by our board of directors. These provisions 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 the acquirer’s own slate of directors or otherwise attempting to obtain control of us.

Calling Special Stockholder Meetings

Our certificate of incorporation and bylaws provide that special meetings of our stockholders may be called only by our board of directors or by stockholders owning at least 25% in amount of our entire capital stock issued and outstanding, and entitled to vote.

Stockholder Action by Written Consent

The DGCL permits stockholder action by written consent unless otherwise provided by our certificate of incorporation. Prior to the 50% Trigger Date, the Designated Controlling Stockholder may take any action that may be taken at a meeting by written consent. On or after the 50% Trigger Date, no action may be taken by written consent in lieu of a stockholders’ meeting.

Undesignated Preferred Stock

Our board of directors is authorized to issue, without stockholder approval, preferred stock with such terms as our board of directors may determine. The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue one or more series of preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of the Company.

Delaware Anti-Takeover Statute

We have elected not to be governed by Section 203 of the DGCL, an anti-takeover law (“Section 203”). This law prohibits a publicly held Delaware corporation from engaging under certain circumstances in a business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

•

prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

•

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, excluding for purposes of determining the number of shares outstanding those shares owned by persons who are directors and also officers and 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

•

on or subsequent to the date of the transaction, the business combination is approved by our board of directors 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 which is not owned by the interested stockholder.

Section 203 defines “business combination” to include: any merger or consolidation involving us and the interested stockholder; any sale, transfer, pledge or other disposition of 10% or more of our assets involving the interested stockholder; in general, any transaction that results in the issuance or transfer by us of any of our stock to 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 us. 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. 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. We have opted out of this provision. Accordingly, we will not be subject to any anti-takeover effects of Section 203. Accordingly, we will not be subject to any anti-takeover effects of Section 203.

Removal of Directors; Vacancies

Our certificate of incorporation provides that, following the 50% Trigger Date, directors may be removed with or without cause upon the affirmative vote of holders of at least two-thirds of the total voting power of the outstanding shares of the capital stock of the Company entitled to vote in any annual election of directors or class of directors, voting together as a single class. In addition, our certificate of incorporation provides that vacancies, including those resulting from newly created directorships or removal of directors, may only be filled (i) by the Designated Controlling Stockholder or by a majority of the directors then in office, prior to the 50% Trigger Date, and (ii) after the 50% Trigger Date, by a majority of the directors then in office, in each case although less than a quorum, or by a sole remaining director. This may deter a stockholder from increasing the size of our board of directors and gaining control of the board of directors by filling the remaining vacancies with its own nominees.

Limitation on Directors’ Liability

Our certificate of incorporation and bylaws will indemnify our directors to the fullest extent permitted by the DGCL. The DGCL permits a corporation to limit or eliminate a director’s personal liability to the corporation or the holders of its capital stock for breach of duty. This limitation is generally unavailable for acts or omissions by a director which (i) were in bad faith, (ii) were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated or (iii) involved a financial profit or other advantage to which such director was not legally entitled. The DGCL also prohibits limitations on director liability for acts or omissions which resulted in a violation of a statute prohibiting certain dividend declarations, certain payments to stockholders after dissolution and particular types of loans. The effect of these provisions is to eliminate the rights of our Company and our stockholders (through stockholders’ derivative suits on behalf of our Company) to recover monetary damages against a director for breach of fiduciary duty as a director (including breaches resulting from grossly negligent behavior), except in the situations described above. These provisions will not limit the liability of directors under the federal securities laws of the United States.

Debt Facilities

Under our existing debt facilities, a change of control may permit the lenders to exercise remedies, such as acceleration of their loans, termination of their obligations to fund additional advances and collection against the collateral securing such loan.

Choice of Forum

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the exclusive forum for: (a) any derivative action or proceeding brought on our behalf; (b) any action asserting a breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders; (c) any action asserting a claim pursuant to any provision of the DGCL, our certificate of incorporation or our bylaws; or (d) any action asserting a claim governed by the internal affairs doctrine. However, it is possible that a court could find our forum selection provision to be inapplicable or unenforceable.

Registration Rights
