Our Company

We are a fiber-based bandwidth infrastructure provider in the Mid-Atlantic region. We provide services to over 1,500 customers, including carriers, healthcare providers, local government agencies, financial institutions, educational institutions, and other enterprises over our advanced fiber network. Our principal products and services include Multiprotocol Label Switching (“MPLS”) and Ethernet / Metro E, Fiber to the Cell (“FTTC”) wireless backhaul and fiber transport services, data center wavelength transport services and IP services.

The following map identifies the features of our fiber network:

S-1

Our industry continues to experience significant increases in global data traffic. The proliferation of smartphones and other network connected devices, the increase in rich media applications, the rise of cloud computing, the deployment of 4G LTE mobile broadband, and the trend towards outsourced enterprise IT and storage services are driving demand for increased connectivity and speed. According to the Cisco Index, global tablet, mobile phone, and machine-to-machine IP traffic is anticipated to grow 104%, 79%, and 82%, respectively, from 2012 through 2017. The Cisco Index estimates that U.S. mobile IP traffic is forecasted to grow approximately nine times from 2012 through 2017, while business IP traffic is expected to nearly triple over the same period. We believe that fiber represents the only transport medium currently capable of supporting these increasing bandwidth demands.

We leverage our fiber assets to capture the continued rapid growth in demand for data and mobility services in the second- and third-tier markets we primarily serve. Compared to first-tier cities, the majority of our markets have a favorable competitive landscape, as there are currently fewer other competitors present. We believe this landscape, combined with our unique network and the strength of our customer relationships, provides us with a sustainable competitive advantage in many of our markets.

As of September 30, 2013, our fiber network spanned approximately 5,800 long-haul fiber route miles. We currently connect to 540 cell towers, approximately 1,300 buildings and 12 data center locations. Based on internal estimates, there are approximately 4,000 cell sites within five miles of our network, over 20,000 buildings within one mile of our network and approximately 80 data centers within our markets. We believe there is a significant opportunity for us to leverage our existing fiber footprint to compete for these opportunities within our markets. To assist us in capturing this opportunity, we have strengthened our management team with recent hires over the last 18 months and intend to drive growth by focusing on leveraging our strategic fiber assets to deliver next-generation communications services.

Our Segments and Services

Beginning in the first quarter of 2013, we restructured our operating segments to more closely align with our product and service offerings, which coincides with the way that we measure performance and allocate resources. We have three reportable operating segments—strategic data, legacy voice and access.

Strategic Data

Our strategic data segment includes our carrier data, enterprise data and IP services product groups and represents the focal point of our growth strategy. We market and sell these services primarily to carrier and enterprise clients, including healthcare providers, local government agencies, financial institutions, educational institutions, and data centers. Given our focus on on-net customers, our strategic data services typically carry higher gross margins than many of our other product lines. A significant majority of our capital expenditures and sales force are dedicated to increasing revenue and profits from our strategic data segment.

We believe that a balanced split between carrier and enterprise revenue results in the most effective capital allocation and resulting profitability. For example, adding a new on-net building brings us closer to nearby cell sites, thus providing an opportunity for FTTC growth, and adding a new cell site brings us closer to nearby on-net buildings and provides an opportunity for enterprise growth. Our ability to sustain revenue growth in our strategic data segment depends on our effectively deploying capital and implementing our FTTC and edge-out plans in a timely and disciplined manner, attracting new customers and upselling existing customers.

We generate growth within our strategic data segment through increased bandwidth demand, particularly for long-term FTTC contracts from wireless carriers deploying 4G LTE services, improving enterprise penetration

S-2

within our existing markets and selling into the edge-out markets. We have added 279 FTTC sites over the last 12 months, representing a year over year increase of over 100%, and 153 on-net buildings, representing an increase of 13% over the last 12 months. Our sales force is focused on capitalizing on these sources of growth as we are organized into carrier and enterprise teams to effectively pursue the opportunity.

Legacy Voice and Access

Our legacy voice segment includes our local lines, primary rate interface (“PRI”), long distance, toll and directory advertising and other voice services, excluding voice over IP (“VoIP”) which is typically provided to enterprise customers and is included in our strategic data segment. These products are sold to enterprise and residential customers on our network.

Our access segment provides carrier customers access to our network within our footprint and primarily includes switched access and reciprocal compensation products.

These legacy businesses, in the aggregate, require limited incremental capital and personnel investment to maintain the underlying assets and deliver reasonably predictable cash flows. We currently expect aggregate revenue from these businesses will continue to decline at an annual rate of approximately 15%. Despite the declining revenues, we expect the cash flows from these businesses to continue to significantly contribute to funding the capital expenditures for our growing strategic data segment.

Our Network and Platform

We have developed a robust, dense network of long-haul fiber, metro Ethernet and Ethernet rings located primarily in Virginia and West Virginia, and portions of Pennsylvania, Maryland, Ohio and Kentucky. As of September 30, 2013, our fiber network spanned approximately 5,800 long-haul fiber route miles. To support the continued surge in network traffic, in July 2013, we launched 100 Gbps wavelength services across our entire Mid-Atlantic footprint. We believe our 100 Gbps capability, which provides greater throughput and superior latency performance, is attractive to carrier and enterprise customers.

Our integrated fiber transport network allows us to offer a suite of advanced next generation communications services, including, but not limited to, multi-site networking, dedicated Internet and Metro Ethernet Forum (“MEF”) 2.0 certified Ethernet solutions, high-speed Internet and VoIP services. We use a multi-vendor approach, including Cisco and Ciena, among others, to deliver high speed wavelength services directly to end customers or as infrastructure for the MPLS Ethernet and high-speed Internet backbone. Network-to-network interconnection points allow us to engage carrier partners to provide end to end service for carrier and enterprise customers. We continue to invest in our fiber network to support the deployment of next-generation products and services, expand our addressable market and bring new customers on-net.

Our local networks consist of central office digital switches, routers, loop carriers and virtual and physical colocations interconnected primarily with fiber facilities. A mix of fiber optic and copper facilities connect our customers with the core network. Our network operations center provides technical surveillance of our network using IBM-based network management systems.

In June 2013, we launched an upgrade of our internal business processes and systems including provisioning, billing and customer care, which will allow us to scale our back office systems as our business continues to grow. We expect to begin realizing the benefits of this initiative in 2014, including operating efficiencies, improved customer facing capabilities and streamlined business processes.

S-3

Our Competitive Strengths

We believe the following competitive strengths will help us successfully execute our business strategy:

• our advanced fiber network, which allows us to provide next generation communication solutions and tailored services to our customers;

• our footprint, including greenfield contiguous markets, which we believe provides significant opportunities for growth with a favorable competitive environment relative to first-tier markets;

• our robust and expanding products and services, including FTTC and Metro Ethernet, and increasing customer bandwidth demands, both of which drive our growth;

• our disciplined, success-based capital investment strategy aimed at maximizing our capital efficiency and delivering attractive returns;

• our diverse customer base, which we believe affords us significant opportunities to upsell additional advanced data products and solutions;

• our strong liquidity position and cash flow visibility from our legacy voice and access segments, which we believe will allow us to fund our growth plan; and

• our experienced management team, with deep industry experience and a strong track record of operating and scaling bandwidth infrastructure assets.

Operating Strategy

Our overall strategy is to:

• monetize our fiber optic network by selling bandwidth infrastructure services to new and existing carrier and enterprise customers while maintaining approximately 70 – 80% of our strategic data revenue from on-net traffic;

• leverage our balanced mix of carrier and enterprise customers to increase the density of our network in our existing markets;

• provide competitive value proposition and high quality customer service with in-market relationships and support;

• use our edge-out strategy to expand into new adjacent geographic markets to expand our addressable market; and

• execute our success-based investment strategy to improve capital efficiency and expand margins.

The core tenets of our growth strategy include:

Continue to Scale Our FTTC Revenue Stream

As demand continues to increase for 4G LTE services, wireless carriers are upgrading their backhaul networks from legacy copper based T1s and even Ethernet over SONET connections to native Ethernet in order to handle the exponential need for capacity. To meet this need, we provide FTTC backhaul solutions and transport services to multiple large telecommunications providers who operate in our markets, where our wireless carrier customers are upgrading to 4G LTE services. As of September 30, 2013, we provided FTTC backhaul solutions to 540 sites. We are targeting having FTTC connectivity to 1,500 of the approximately 4,000 cell sites within five miles of our network over the next several years to capitalize on the growth opportunity in our footprint. Based on wireless carrier plans to upgrade to 4G LTE and associated bandwidth growth, together with our knowledge of and experience in the markets we serve, we anticipate long-term growth in tenants, bandwidth and monthly revenue per FTTC site across our addressable market.

S-4

Drive Incremental On-Net Data Traffic

Our on-net strategy focuses on driving traffic through our network, thereby providing economies of scale and increasing profitability. As bandwidth demand grows, we are able to drive incremental revenue through our existing network with minimal increase in operating expenses or capital expenditures. We evaluate this on-net approach and the associated capital expenditure against the revenue opportunity and have determined that maintaining approximately 70 – 80% of our strategic data revenue from on-net traffic is the most effective use of capital.

Edge-Out into Key Markets Adjacent to Our Existing Network Footprint

Our edge-out strategy expands our fiber network into new contiguous markets based on demand from existing customers and by leveraging existing assets. We also employ experienced in-market sales teams to drive growth. Our current edge-out markets include Richmond, VA and Western PA, which meaningfully increase our addressable market. We had an existing customer which needed alternative solutions in Richmond, VA, and signed a multi-year contract for our services, thus providing us with an anchor to support our expansion into this market. We recently completed the build out of our 110 metro-mile fiber network in Richmond, VA and lit up the network, with anchor enterprise and carrier customers already under contract. In Western PA, we own fiber assets and can leverage these assets to build out metro Ethernet and Ethernet rings. As we edge-out into new markets, we are able to bring new carrier customers, cell sites and enterprise customers onto our fiber networks, thus significantly increasing our addressable market.

Disciplined Success-Based Capital Investment Strategy

We seek to maximize our capital expenditure efficiency by requiring that a significant percentage of our capital investment be tied to specific revenue generating projects based on customer commitments, which we refer to as “success-based projects”. We also maximize our capital expenditure efficiency by pursuing on-net and near-net customer opportunities and maintaining a balanced mix of carrier and enterprise business. Our capital investment strategy targets a 15% – 20% return on investment and a less than 4-year payback. During the nine months ended September 30, 2013, 77% of our funds committed to capital projects were for success-based projects. Since the beginning of 2012, we have invested approximately $88 million of capital within our strategic data segment, the vast majority of which was allocated to success-based projects. Our goal is to continue to achieve a similar ratio of success-based projects to total capital expenditures.

(3) In December 2012, we completed a cost reduction plan involving an employee reduction-in-force, consolidation of certain facilities and freezing the accumulation of benefits under certain postretirement plans. Restructuring charges of $3.0 million were recognized in the fourth quarter of 2012 in connection with this plan, $2.4 million of which related to employee severance and termination benefits and $0.6 million of which related to lease termination costs.

(4) We evaluate our performance based upon Adjusted EBITDA (a measure that is not determined in accordance with U.S. generally accepted accounting principles (“GAAP”)), defined by us as net income or loss attributable to us before interest, income taxes, depreciation and amortization, accretion of asset retirement obligations, net income or loss attributable to noncontrolling interests, other income or expenses, equity-based compensation charges, acquisition-related charges, amortization of actuarial losses on retirement plans, employee separation charges, restructuring-related charges, gain or loss on settlements and gain or loss on interest rate derivatives. The following table provides a reconciliation of our operating income (a GAAP financial measure) to our Adjusted EBITDA (a non-GAAP financial measure) for the indicated periods:

Adjusted EBITDA is a non-GAAP financial performance measure. It should not be considered in isolation, as an alternative to, or more meaningful than measures of financial performance determined in accordance with GAAP. We believe that Adjusted EBITDA is a standard measure of operating performance and liquidity that is commonly reported in the telecommunications and high speed data transport industry and provides relevant and useful information to investors for comparing performance period to period and for comparing financial performance of similar companies. However, our calculation of Adjusted EBITDA may not be comparable to other similarly-titled measures of other companies and should not be considered in isolation or as a substitute for analysis of our operating results as reported under GAAP. We utilize Adjusted EBITDA internally to assess our ability to meet future capital expenditure and working capital requirements, to incur indebtedness if necessary, and to fund continued growth. We also use Adjusted EBITDA to evaluate the performance of our business for budget planning purposes and as factors in our employee compensation programs.

(5) During 2010, we received a Federal stimulus award providing 50% funding to bring broadband services and infrastructure to Alleghany County, Virginia. We were required to deposit 100% of our grant ($8.1 million) into pledged accounts in advance of any reimbursements, to be drawn down ratably following reimbursement approvals.

RISK FACTORS

An investment in our common stock involves risks. You should carefully consider the specific risks set forth in this prospectus supplement and the accompanying prospectus and the risks described in our Annual Report on Form 10-K for the year ended December 31, 2012 and our Quarterly Reports on Form 10-Q for the six months ended June 30, 2013 and the nine months ended September 30, 2013, which are incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision. You should also consider similar information contained in any Annual Report on Form 10-K, Quarterly Report on Form 10-Q or other document filed by us with the SEC after the date of this prospectus supplement before deciding to invest in our common stock. The occurrence of any such risks might cause you to lose all or part of your investment in our common stock. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations and financial condition.

Risks Relating to this Offering and our Common Stock

The Quadrangle Entities will continue to have significant influence over our business after this offering and could delay, deter or prevent a change of control, change in management or business combination that may be beneficial to our stockholders, and as a result, may depress the market price of our common stock.

Upon completion of this offering, the Quadrangle Entities (as defined in the section entitled “Selling Stockholders”) will beneficially own 3,168,716 shares of our common stock, or approximately 14.4% of our outstanding common stock. If the underwriters’ option to purchase 376,818 additional shares is exercised in full, the Quadrangle Entities will beneficially own 2,791,898 shares of our common stock, or approximately 12.7% of our outstanding common stock. In addition, two of the eight directors who serve on our board of directors will be representatives or designees of the Quadrangle Entities. Pursuant to the terms of the Stockholders Agreement (as defined in the section entitled “Selling Stockholders”), the Quadrangle Entities currently have the right to nominate three directors. One of the three directors designated by the Quadrangle Entities currently must be “independent” as defined by the rules of The NASDAQ Stock Market. Pursuant to the Stockholders Agreement, the Quadrangle Entities may designate only two directors, who do not need to be “independent,” if their ownership falls below 20% of the voting power of our common stock, one director, who does not need to be “independent,” if their ownership falls below 10% and no directors if their ownership falls below 5%. The Stockholders Agreement also provides that one director will be our Chief Executive Officer for so long as he or she is employed by us. Upon completion of this offering, the Quadrangle Entities’ ownership of our common stock will fall below 20% of the voting power of our common stock, and, as result, they may continue to designate two directors who do not need to be “independent.”

By virtue of the Stockholder’s Agreement and such stock ownership and representation on the board of directors, the Quadrangle Entities will continue to have a significant influence over day-to-day corporate and management policies and all matters submitted to our stockholders, including the election of the directors, and to exercise significant control over our business, policies and affairs. Such concentration of voting power could have the effect of delaying, deterring or preventing a change of control, a change in management or a business combination that might otherwise be beneficial to our stockholders and as a result, may depress the market price of our common stock.

The interests of the Quadrangle Entities may not coincide with the interests of a holder of our common stock and because the Quadrangle Entities will continue to have significant influence over our business, they could cause us to enter into transactions or agreements adverse to the interests of our other stockholders.

The interests of the Quadrangle Entities may not always coincide with the interests of our other stockholders. Accordingly, because the Quadrangle Entities will continue to have significant influence over our business after the closing of this offering, they could cause us to enter into transactions or agreements adverse to the interests of our other stockholders.

S-10

In addition, the Quadrangle Entities are in the business of making investments in companies and may, from time to time, acquire and hold interests in businesses that compete directly or indirectly with us. The Quadrangle Entities may also pursue, for their own account, acquisition opportunities that may be complementary to our business, and as a result, those acquisition opportunities may not be available to us. Additionally, we have specifically renounced in the Shareholders Agreement (as defined in the section entitled “Selling Stockholders”) any interest or expectancy that the Quadrangle Entities will offer to us any investment or business opportunity of which they are aware.

The shares of our common stock being sold in this offering by the selling stockholders were not freely tradable on The Nasdaq Global Market prior to the completion of this offering, and the sale by the selling stockholders of the shares of our common stock in this offering will increase the number of shares of our common stock eligible to be freely traded on The Nasdaq Global Market, which could depress the market price of our common stock.

Of the 22,022,899 shares of our common stock issued and outstanding as of October 28, 2013, approximately 25.8% was held by the selling stockholders. The remainder of our shares of issued and outstanding common stock are freely tradable on The Nasdaq Global Market without restriction or further registration under the Securities Act of 1933, as amended (the “Securities Act”), unless such shares constitute “restricted securities” within the meaning of Rule 144 under the Securities Act or are purchased by our “affiliates” as that term is defined in Rule 144 under the Securities Act. The shares of common stock being sold in this offering were not freely tradable on The Nasdaq Global Market prior to the completion of this offering and the sale by the selling stockholders of the shares of common stock in this offering will increase the number of shares of our common stock eligible to be freely traded on The Nasdaq Global Market, which could depress the market price of our common stock.

On October 30, 2013, our board of directors declared a quarterly dividend on our common stock in the amount of $0.14 per share to be paid on January 9, 2014 to stockholders of record on December 12, 2013. We currently intend to continue to pay regular quarterly dividends on our common stock at a rate of $0.14 per share. All decisions to declare future dividends will be made at the discretion of the board of directors and will depend on, among other things, our results of operations, cash requirements, investment opportunities, financial condition, credit agreement and contractual restrictions and other factors that the board of directors may deem relevant. We are a holding company that does not operate any business of our own. As a result, we are dependent on cash dividends and distributions and other transfers from our subsidiaries to make dividend payments or other distributions to our stockholders. Amounts that can be made available to us to pay cash dividends will be permitted by our credit agreement within the parameters of a restricted payment basket.

As of March 1, 2013, there were approximately 3,300 record holders of our common stock.

UNDERWRITING

Subject to the terms and conditions stated in the underwriting agreement, the selling stockholders have agreed to sell to the underwriters named below, and the underwriters, for whom Wells Fargo Securities, LLC and Cowen and Company, LLC are acting as joint book-running managers and representatives, have, severally and not jointly, agreed to purchase from the selling stockholders, the respective number of shares of common stock appearing opposite their names below.

Underwriters	Number of Shares of Common Stock

Cowen and Company, LLC		906,876
D.A. Davidson & Co.		188,409
Canaccord Genuity Inc.		125,606
Drexel Hamilton, LLC		125,606
Total		2,512,121

The underwriting agreement provides that the obligations of the several underwriters are subject to various conditions, including approval of legal matters by counsel. The underwriters are obligated, severally and not jointly, to purchase all of the common stock (other than those covered by the option to purchase additional shares of common stock described below) if they purchase any of the common stock. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or, under certain limited circumstances, the underwriting agreement may be terminated.

Option to Purchase Additional Common Stock

The selling stockholders have granted the underwriters a 30-day option, exercisable from the date of this prospectus supplement, to purchase up to an additional 376,818 shares of common stock from the selling stockholders at the public offering price less the underwriting discounts and commissions. To the extent the option is exercised, each underwriter must, subject to the terms and conditions contained in the underwriting agreement, purchase a number of additional shares of common stock approximately proportionate to that underwriters’ initial purchase commitment.

Underwriting Discounts and Expenses

The underwriters propose to offer some of the shares of common stock directly to the public at the public offering price set forth on the cover page of this prospectus supplement and some of the shares of common stock to dealers at the public offering price less a concession not to exceed $0.60 per share of common stock. After the offering, the underwriters may change the public offering price and the other selling terms. The offering of the shares of common stock by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The following table summarizes the underwriting discounts and commissions and the proceeds, before expenses, payable to the selling stockholders, both on a per share basis and in total, assuming either no exercise or full exercise by the underwriters of their option to purchase additional common stock from the selling stockholders.

	Per Share		Total
			No Exercise		Full Exercise
Public offering price	$	20.00	$	50,242,420	$	57,778,780

Proceeds, before expenses, to the selling stockholders	$	18.90	$	47,479,087	$	54,600,947

S-17

We estimate that our total expenses of this offering, other than underwriting discounts and commissions, will be approximately $700,000 and are payable by us. We have also agreed to reimburse the underwriters for certain of their expenses relating to required reviews by FINRA in an amount up to $10,000.

Lock-Up Agreements

We, all of our directors and executive officers, the selling stockholders and their affiliates have agreed that, subject to certain exceptions (including in connection with change of control transactions, to us to satisfy tax withholding obligations and up to 5% of our issued and outstanding common stock by us in connection with strategic transactions), without the prior written consent of Wells Fargo Securities, LLC and Cowen and Company, LLC, we and they will not directly or indirectly (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of common stock (including, without limitation, shares of common stock that may be deemed to be beneficially owned by us or them in accordance with the rules and regulations of the SEC and shares of common stock that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for common stock (other than the shares of common stock offered for sale by the selling stockholders as described in this prospectus supplement), (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of the common stock, (3) cause to be filed a registration statement with respect to any shares of common stock or securities convertible, exercisable or exchangeable into common stock or any of our other securities, or (4) publicly disclose the intention to do any of the foregoing for a period of 90 days after the date of this prospectus supplement.

To the extent any of the underwriters in this offering are unable to publish research reports on us under Rule 139 of the Securities Act and/or pursuant to NASD Rule 2711 of the rules and regulations of the Financial Industry Regulatory Authority, the 90-day restricted period described in the preceding paragraph will be extended if:

• during the last 17 days of the 90-day restricted period we issue an earnings release or material news or a material event relating to us occurs; or

• prior to the expiration of the 90-day restricted period, we announce that we will release earnings results during the 16-day period beginning on the last day of the 90-day period;

in which case the restrictions described in the preceding paragraph will continue to apply until the expiration of the 18-day period beginning on the date of issuance of the earnings release or the announcement of the material news or material event, unless such extension is waived in writing by each of Wells Fargo Securities, LLC and Cowen and Company, LLC.

Listing on The NASDAQ Global Market

Our shares of common stock are listed on The Nasdaq Global Market under the symbol “LMOS.”

Price Stabilization, Short Positions and Penalty Bids

In connection with the offering, the underwriters may purchase and sell common stock in the open market. These transactions may include short sales, covering transactions and stabilizing transactions. Short sales involve sales of common stock in excess of the number of common stock to be purchased by the underwriters in the offering, which creates a short position. “Covered” short sales are sales of common stock made in an amount up to the number of common stock represented by the underwriters’ option to purchase additional shares. In determining the source of common stock to close out the covered short position, the underwriters will consider, among other things, the price of common stock available for purchase in the open market as compared to the price at which they may purchase shares of common stock through the option to purchase additional shares. Transactions to close out the covered short position involve either purchases of the common stock in the open market after the distribution has been completed or the exercise of the option to purchase additional shares. The underwriters may also make “naked” short sales of common stock in excess of the option to purchase additional

S-18

shares. The underwriters must close out any naked short position by purchasing common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of common stock in the open market while the offering is in progress.

The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when it repurchases common stock originally sold by that syndicate member in order to cover syndicate short positions or make stabilizing purchases.

Any of these activities may have the effect of preventing or retarding a decline in the market price of the common stock. They may also cause the price of the common stock to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions on The NASDAQ Global Market or in the over-the-counter market, or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time. Neither we nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the common stock.

Certain Relationships

The underwriters and their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriters and their related entities have performed and may perform investment and commercial banking and advisory services for us and our affiliates from time to time, for which they have received and may receive customary fees and expense reimbursement. The underwriters and their affiliates may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business.

In addition, in the ordinary course of their various business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve securities and instruments of the issuer. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Electronic Distribution

This prospectus supplement in electronic format may be made available on the websites maintained by the underwriters. The underwriters may agree to allocate a number of shares of common stock for sale to their online brokerage account holders. The common stock will be allocated to the underwriters, which may make Internet distributions on the same basis as other allocations. In addition, shares of common stock may be sold by the underwriters to securities dealers who resell shares of common stock to online brokerage account holders.

Other than this prospectus supplement in electronic format, information contained in any websites maintained by the underwriters is not part of this prospectus supplement or registration statement of which this prospectus supplement forms a part, has not been endorsed by us and should not be relied on by investors in deciding whether to purchase common stock. The underwriters are not responsible for information contained in websites that they do not maintain.

S-19

Indemnification

We, and the selling stockholders, have agreed, joint and severally, to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

Sales Outside the United States

No action has been taken in any jurisdiction (except in the United States) that would permit a public offering of the common stock or the possession, circulation or distribution of this prospectus supplement or any other material relating to us or the common stock in any jurisdiction where action for that purpose is required. Accordingly, the common stock may not be offered or sold, directly or indirectly, and neither this prospectus supplement nor any other offering material or advertisements in connection with the common stock may be distributed or published, in or from any country or jurisdiction, except in compliance with any applicable rules and regulations of any such country or jurisdiction.

MATERIAL U.S. FEDERAL TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following discussion is a summary of the material U.S. federal income tax consequences to non-U.S. holders (as defined below) of the purchase, ownership and disposition of our common stock issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, including, without limitation, estate and gift tax laws, and any applicable state, local or foreign tax laws are not discussed. This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”) in effect as of the date of this offering. These authorities may change or be subject to differing interpretations. Any such change may be applied retroactively in a manner that could adversely affect a non-U.S. holder of our common stock. We have not sought and will not seek any rulings or other guidance from the IRS regarding the matters discussed below. Consequently, there can be no assurance the IRS or a court will not take a contrary position regarding the tax consequences of the purchase, ownership and disposition of our common stock.

This discussion is limited to non-U.S. holders that hold our common stock as a “capital asset” within the meaning of Section 1221 of the Code (property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a non-U.S. holder’s particular circumstances, including the impact of the unearned income Medicare contribution tax. In addition, it does not address consequences relevant to non-U.S. holders subject to particular rules, including, without limitation:

• U.S. expatriates and certain former citizens or long-term residents of the United States;

• persons subject to the alternative minimum tax;

• persons holding our common stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

• banks, insurance companies, and other financial institutions;

• real estate investment trusts or regulated investment companies;

• brokers, dealers or traders in securities;

• “controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

• tax-exempt organizations or governmental organizations;

• persons deemed to sell our common stock under the constructive sale provisions of the Code;

• persons who hold or receive our common stock pursuant to the exercise of any employee stock option or otherwise as compensation; and

• tax-qualified retirement plans.

If a partnership (or other entity treated as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding our common stock and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

S-22

Definition of a Non-U.S. Holder

For purposes of this discussion, a “non-U.S. holder” is any beneficial owner of our common stock that is neither a “U.S. person” nor a partnership for U.S. federal income tax purposes. A U.S. person is any of the following:

• an individual who is a citizen or resident of the United States;

• a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof, or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

• a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more United States persons (within the meaning of Section 7701(a)(30) of the Code), or (2) has made a valid election under applicable Treasury Regulations to be treated as a United States person.

Distributions

Cash or other property distributions on our common stock generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a non-U.S. holder’s adjusted tax basis in its common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below in the section relating to the sale or disposition of our common stock.

Subject to the discussion below on backup withholding and foreign accounts, dividends paid to a non-U.S. holder of our common stock that are not effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or a lower rate specified by an applicable income tax treaty).

Non-U.S. holders will be entitled to a reduction in or an exemption from withholding on dividends as a result of either (a) an applicable income tax treaty or (b) the non-U.S. holder holding our common stock in connection with the conduct of a trade or business within the United States and dividends being paid in connection with that trade or business. To claim such a reduction in or exemption from withholding, the non-U.S. holder must provide the applicable withholding agent with a properly executed (a) IRS Form W-8BEN (or successor form) claiming an exemption from or reduction of the withholding tax under the benefit of an income tax treaty between the United States and the country in which the non-U.S. holder resides or is established, or (b) IRS Form W-8ECI (or successor form) stating that the dividends are not subject to withholding tax because they are effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States, as may be applicable. These certifications must be provided to the applicable withholding agent prior to the payment of dividends and must be updated periodically. Non-U.S. holders failing to timely provide the applicable withholding agent with the required certification, but otherwise qualifying for a reduced rate under an applicable income tax treaty, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Subject to the discussion below on backup withholding and foreign accounts, if dividends paid to a non-U.S. holder are effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such dividends are attributable), then, although exempt from U.S. federal withholding tax (provided the non-U.S. holder provides appropriate certification, as described above), the non-U.S. holder will be subject to U.S. federal income tax on such dividends on a net income basis at the regular graduated U.S. federal income tax rates. In addition, a non-U.S. holder that is a corporation may be subject to a branch profits tax at a rate of 30% (or a lower rate specified by an applicable income tax treaty) on its effectively

S-23

connected earnings and profits for the taxable year that are attributable to such dividends, as adjusted for certain items. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

Sale or Other Taxable Disposition

Subject to the discussions below on backup withholding and foreign accounts, a non-U.S. holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of our common stock unless:

• the gain is effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such gain is attributable);

• the non-U.S. holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

• our common stock constitutes a U.S. real property interest, or USRPI by reason of our status as a U.S. real property holding corporation, or USRPHC, for U.S. federal income tax purposes.

Gain described in the first bullet point above will generally be subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal income tax rates. A non-U.S. holder that is a foreign corporation also may be subject to a branch profits tax at a rate of 30% (or a lower rate specified by an applicable income tax treaty) of a portion of its effectively connected earnings and profits for the taxable year, as adjusted for certain items.

A non-U.S. holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or a lower rate specified by an applicable income tax treaty) on any gain derived from the disposition, which may be offset by certain U.S. source capital losses of the non-U.S. holder (even though the individual is not considered a resident of the United States) provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe we are not currently and do not anticipate becoming a USRPHC. Because the determination of whether we are a USRPHC depends on the fair market value of our USRPIs relative to the fair market value of our other business assets and our non-U.S. real property interests, however, there can be no assurance we are not a USRPHC or will not become one in the future. Even if we are or were to become a USRPHC, gain arising from the sale or other taxable disposition by a non-U.S. holder of our common stock will not be subject to U.S. federal income tax if such class of stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market, and such non-U.S. holder owns, actually or constructively, 5% or less of such class of our stock throughout the shorter of the five-year period ending on the date of the sale or other disposition or the non-U.S. holder’s holding period for such stock.

Non-U.S. holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

A non-U.S. holder will not be subject to backup withholding with respect to payments of dividends on our common stock we make to the non-U.S. holder, provided the applicable withholding agent does not have actual knowledge or reason to know such holder is a United States person and the holder certifies its non-U.S. status, such as by providing a valid IRS Form W-8BEN or W-8ECI, or other applicable certification. However, information returns will be filed with the IRS in connection with any dividends on our common stock paid to the non-U.S. holder, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the non-U.S. holder resides or is established.

S-24

Information reporting and backup withholding may apply to the proceeds of a sale of our common stock within the United States, and information reporting may (although backup withholding generally will not) apply to the proceeds of a sale of our common stock outside the United States conducted through certain U.S.-related financial intermediaries, in each case, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder on IRS Form W-8BEN or other applicable form (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person) or such owner otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under the Code provisions commonly known as the Foreign Account Tax Compliance Act (“FATCA”) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or gross proceeds from the sale or other disposition of, our common stock paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and recently-issued IRS guidance, withholding under FATCA generally will apply to payments of dividends on our common stock made on or after July 1, 2014 and to payments of gross proceeds from the sale or other disposition of such stock on or after January 1, 2017.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our common stock.

Certain Relationships and Transactions

Our board of directors currently consists of eight members. Pursuant to the terms of our Shareholders Agreement, the Quadrangle Entities currently have the right to nominate three directors. One of the three directors designated by the Quadrangle Entities currently must be “independent” as defined by the rules of The NASDAQ Stock Market. Pursuant to the Shareholders Agreement, the Quadrangle Entities may designate only two directors, who do not need to be “independent,” if their ownership falls below 20% of the voting power of our common stock, one director, who does not need to be “independent,” if their ownership falls below 10% and no directors if their ownership falls below 5%. The Shareholders Agreement also provides that one director will be our Chief Executive Officer for so long as he or she is employed by us. In accordance with the Shareholders Agreement, the Quadrangle Entities and the other management shareholders party thereto each are required to vote for such nominees and take all other necessary action to ensure that these nominees are elected to the Board of Directors.

In accordance with the Shareholders Agreement, we may not take certain significant actions, such as a merger or sale of assets in excess of $3 million, incurrences of indebtedness, amendments of organizational documents and certain other matters, subject to certain specified exceptions, without the approval of a majority of the members of the board of directors. The required quorum for any meeting of the board of directors must include at least one director designated by, and affiliated with, the Quadrangle Entities, for as long as the Quadrangle Entities are entitled to designate one or more members of the board of directors in accordance with the terms of the Shareholders Agreement.

The Shareholders Agreement covers other matters of corporate governance, restrictions on transfer of our securities, registration rights and information rights.

PLAN OF DISTRIBUTION

The selling stockholders currently intend to offer and sell pursuant to one or more prospectus supplements, from time to time, the securities offered by this prospectus, in one or more underwritten or other public offerings and at prices and on terms that will be determined at the time of the offering. The selling stockholders initially acquired their shares of our common stock in private placement transactions completed prior to the date of this prospectus. We will pay for all costs, expenses and fees in connection with the registration of the securities. In addition, we have agreed to indemnify the selling stockholders against certain liabilities in connection with offerings of the shares of common stock. The selling stockholders will pay for all selling discounts and commissions, if any, on the shares of stock offered by them.

However, the selling stockholders also may offer and sell securities, as applicable:

• through agents or underwriters;

• through a block trade in which the broker or dealer engaged to handle the block trade will attempt to sell the securities as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

• directly to one or more purchasers (through a specific bidding or auction process or otherwise); or

• through a combination of any of these methods of sale.

The distribution of our securities may be effected from time to time in one or more transactions either:

• at a fixed price or prices, which may be changed;

• at market prices prevailing at the time of sale;

• at prices relating to the prevailing market prices; or

• at negotiated prices.

Offers to purchase our securities may be solicited by agents designated by the selling stockholders from time to time. Any agent involved in the offer or sale of our securities will be named, and any commissions payable by us and/or the selling stockholders to the agent will be described, in the applicable prospectus supplement. Unless otherwise indicated in the applicable prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment. Any agent may be deemed to be an underwriter, as such term is defined in the Securities Act, of the securities so offered and sold.

The selling stockholders may transfer their shares of common stock in ways not involving market makers or established trading markets, including directly by gift, distribution, or other transfer. The selling stockholders may also sell any shares of common stock that qualify for sale pursuant to Rule 144.

If the selling stockholders offer and sell our securities through an underwriter or underwriters, we and/or the selling stockholders will execute an underwriting agreement with the underwriter or underwriters. The names of the specific managing underwriter or underwriters, as well as any other underwriters, and the terms of the transactions, including compensation of the underwriters and dealers, which may be in the form of discounts, concessions or commissions, if any, will be described in the applicable prospectus supplement, which, along with this prospectus, will be used by the underwriters to make resales of our securities. If underwriters are used in the sale of any of our securities in connection with this prospectus, those securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at fixed public offering prices or at varying prices determined by the underwriters and us and/or the selling stockholders at the time of sale. Our securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more underwriters, If any underwriter or underwriters are used in the sale of our securities, unless otherwise indicated in a related

6

prospectus supplement, the underwriting agreement will provide that the obligations of the underwriters are subject to some conditions precedent and that with respect to a sale of our securities the underwriters will be obligated to purchase all such securities if any are purchased.

If any underwriters are involved in the offer and sale of our securities, they will be permitted to engage in transactions that maintain or otherwise affect the price of such securities or other securities of ours, These transactions may include over-allotment transactions, purchase to cover short positions created by an underwriter in connection with the offering and the imposition of penalty bids. If an underwriter creates a short position in the securities in connection with the offering, i.e., if it sells more securities than set forth on the cover page of the applicable prospectus supplement, the underwriter may reduce that short position by purchasing securities in the open market. In general, purchases of securities to reduce a short position could cause the price of the securities to be higher than it might be in the absence of such purchases. As noted above, underwriters may also choose to impose penalty bids on other underwriters and/or selling group members. This means that if underwriters purchase securities on the open market to reduce their short position or to stabilize the price of the securities, they may reclaim the amount of the selling concession from those underwriters and/or selling group members who sold such securities as part of the offering.

If the selling stockholders offer and sell our securities through a dealer, the selling stockholders or an underwriter will sell our securities to the dealer, as principal. The dealer may then resell our securities to the public at varying prices to be determined by the dealer at the time of resale. Any such dealer may be deemed to be an underwriter, as such term is defined in the Securities Act, of our securities so offered and sold. The name of the dealer and the terms of the transactions will be set forth in the applicable prospectus supplement.

The selling stockholders may solicit offers to purchase our securities directly and the selling stockholders may sell our securities directly to institutional or other investors, who may be deemed to be an underwriter within the meaning of the Securities Act with respect to any resales of those securities. The terms of these sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement.

We and/or the selling stockholders may enter into agreements with agents, underwriters and dealers under which we may agree to indemnify the agents, underwriters and dealers against certain liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make with respect to these liabilities. The terms and conditions of this indemnification or contribution will be described in the applicable prospectus supplement.

Some of the agents, underwriters or dealers or their affiliates may be customers of, engage in transactions with or perform services for us, the selling stockholders or any of our or their affiliates in the ordinary course of business.

The selling stockholders may authorize our respective agents or underwriters to solicit offers to purchase our securities at the public offering price under delayed delivery contracts. The terms of these delayed delivery contracts, including when payment for and delivery of our securities sold will be made under the contracts and any conditions to each party’s performance set forth in the contracts, will be described in the applicable prospectus supplement. The compensation received by underwriters or agents soliciting purchases of our securities under delayed delivery contracts will also be described in the applicable prospectus supplement.

The selling stockholders may be deemed to be underwriters within the meaning of Section 2(11) of the Securities Act. Any profit they realize on the resale of our common stock may be deemed to be underwriting discounts and commissions under the Securities Act. Neither we nor any selling stockholder can presently estimate the amount of any such compensation.

7

From time to time, the selling stockholders may pledge or grant a security interest in some or all of our shares of common stock owned by them. If the selling stockholders default in the performance of their secured obligations, the pledgees or secured parties may offer and sell such common stock from time to time by this prospectus. The selling stockholders also may transfer, distribute or donate our common stock owned by them in other circumstances. The number of shares of our common stock beneficially owned by selling stockholders will decrease as and when the selling stockholders transfer, distribute or donate their shares of our common stock or default in performing obligations secured by their shares of our common stock. The plan of distribution for the securities offered and sold under this prospectus will otherwise remain unchanged, except that the transferees, distributees, donees, pledgees, other secured parties or other successors in interest will be the selling stockholders for purposes of this prospectus.

Any underwriters who are qualified market makers on the NASDAQ Global Market may engage in passive market making transactions in the common stock on the NASDAQ Global Market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, and before the commencement of offers or sales of the common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

The discussion set forth below describes the most important terms of our common stock, restated certificate of incorporation and by-laws.

For a complete description you should refer to our certificate of incorporation and by-laws, which are filed as exhibits to the registration statement of which this prospectus is a part, and to the applicable provisions of the Delaware General Corporation law.

Set forth below is a brief discussion of the principal terms of our common stock:

Dividend Rights

Holders of our common stock are entitled to receive ratably dividends, if, as and when dividends are declared from time to time by our board of directors out of funds legally available for that purpose, after any dividends required to be paid on outstanding preferred stock, if any. The terms of our credit facility impose restrictions on our ability to declare dividends on our capital stock.

Voting Rights

Each outstanding share of our common stock is entitled to one vote on all matters submitted to a vote of holders of our common stock. The holders of common stock do not have cumulative voting rights in the election of directors.

Preemptive or Similar Rights

Our common stock will not be entitled to preemptive or other similar subscription rights to purchase any of our securities.

Right to Receive Liquidation Distributions

Upon our liquidation, dissolution or winding up, the holders of our common stock will be entitled to receive pro rata our assets which are legally available for distribution, after payment of all debts and other liabilities and subject to the prior rights of any holders of preferred stock then outstanding.

NASDAQ Listing

Our common stock is traded on the NASDAQ Global Market under the symbol “LMOS.”

Shareholders Agreement

We are a party to a Shareholders Agreement with the Quadrangle Entities. For a description of the Shareholders Agreement, see “Selling Stockholders — Certain Relationships and Transactions.” This description is qualified by reference to the Shareholders Agreement which is filed as an exhibit to the registration statement of which this prospectus is a part and incorporated by reference herein.

Anti-takeover Effects of our Certificate of Incorporation and By-laws

Our certificate of incorporation and by-laws 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

9

of delaying, deferring or preventing a future takeover or change in control of the company unless such takeover or change in control is approved by the board of directors, including:

Written Consent of Stockholders

Our certificate of incorporation provides that all corporate powers will be exercised by our board of directors, except as otherwise specifically required by law or otherwise provided in our certificate of incorporation. Our certificate of incorporation and our bylaws do not permit stockholder action by written consent. Any action required or permitted to be taken by our stockholders must be effected at an annual or special meeting of stockholders and may not be effected by the written consent of our stockholders.

Special Meetings

Pursuant to the General Corporation Law of the State of Delaware, or DGCL, a special meeting of stockholders may be called by the board of directors or by any other person authorized to do so in our certificate of incorporation or bylaws. Our bylaws provide that a stockholder may request a special meeting of stockholders subject to the conditions set forth in our bylaws, including that stockholders representing at least 25% of the total number of shares of stock entitled to vote on the matter or matters to be brought before the proposed special meeting request the special meeting of stockholders and that stockholders follow the procedures set forth in our bylaws.

Forum Selection

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 shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws, or (iv) any action asserting a claim governed by the internal affairs doctrine. Our certificate of incorporation further provides that any person or entity purchasing or acquiring any interest in shares of our capital stock shall be deemed to have notice of and to have consented to the provisions described above.

Advance Notice Procedures

Our by-laws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to the board of directors. Stockholders at an annual meeting will only be able to consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the board of directors or by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has given our Secretary timely written notice, in proper form, of the stockholder’s intention to bring that business before the meeting. Although the by-laws do not give the board of directors the power to approve or disapprove stockholder nominations of candidates or proposals regarding other business to be conducted at a special or annual meeting, the by-laws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or defer a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of the company.

No Cumulative Voting

The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless our certificate of incorporation provides otherwise. Our certificate of incorporation expressly provides that no stockholder shall be entitled to cumulate votes in the election of directors.

10

Authorized but Unissued Shares

Our authorized but unissued shares of common stock and preferred stock will be available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain control of a majority of our common stock by means of a proxy contest, tender offer, merger or otherwise.

Transfer Agent and Registrar

Computershare Investor Services, LLC is the transfer agent and registrar for our common stock.
