SUMMARY

This summary highlights certain information concerning our company and this offering. It does not contain all of the information you should consider before making an investment decision. You should carefully read the entire prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein, including the financial statements and related notes, and should consider, among other things, the matters set forth in “Risk Factors” before making an investment decision.

Unless the context requires or is otherwise noted, all references in this prospectus supplement and accompanying prospectus to “SemGroup,” the “Company,” “we,” “us” and “our” refer to SemGroup Corporation, a Delaware corporation, and its consolidated subsidiaries and predecessors.

Our Company

Overview

We are a growth-oriented provider of gathering, transportation, storage, distribution, marketing and other midstream services primarily to producers, refiners of petroleum products and other market participants located in the Midwest and Rocky Mountain regions of the U.S. and Canada. We, or our significant equity method investees, have an asset base consisting of pipelines, gathering systems, storage facilities, terminals, processing plants and other distribution assets located in North American production and supply areas, including the Gulf Coast, Midwest, Rocky Mountain and Western Canadian regions. We also maintain and operate storage, terminal and marine facilities at Milford Haven in the United Kingdom (the “U.K.”) that enable customers to supply petroleum products to markets in the Atlantic Basin. We also operate a network of liquid asphalt cement terminals throughout Mexico. Our operations are conducted directly and indirectly through our primary business segments – Crude Transportation, Crude Facilities, Crude Supply and Logistics, SemGas®, SemCAMS, SemLogistics, SemMexico and SemStream®.

Assets and Operations

We believe that the variety of our assets enables us to offer a broad portfolio of midstream services and helps mitigate seasonal fluctuations that may affect less diverse businesses. At March 31, 2016, our primary business segments owned the following:

 

   

Crude Transportation operates crude oil pipelines and truck transportation businesses in the U.S. Crude Transportation’s assets include:

 

  ¡

a 400-mile crude oil gathering and transportation pipeline system with over 630,000 barrels of associated storage capacity in Kansas and northern Oklahoma that is connected to several third-party pipelines and refineries;

 

  ¡

the Wattenberg Oil Trunkline (“WOT”), a 75-mile, 12-inch diameter crude oil gathering pipeline system that transports crude oil from production facilities in the DJ Basin to the pipeline owned by White Cliffs Pipeline, L.L.C. (“White Cliffs”); the WOT has a capacity of approximately 85,000 barrels per day as well as 360,000 barrels of operational storage;

 

  ¡

a 16-mile crude oil pipeline that connects our Platteville, Colorado crude oil terminal to the Tampa, Colorado crude oil market;

 

  ¡

a crude oil trucking fleet of over 270 transport trucks and 270 trailers;

 



 

S-1


Table of Contents
  ¡

Maurepas Pipeline, a project underway to build three pipelines to service refineries in the Gulf Coast region, which is expected to be completed in the fourth quarter of 2016;

 

  ¡

a 51% ownership interest in White Cliffs, which owns a 527-mile pipeline, consisting of two 12-inch common carrier, crude oil pipelines, that transports crude oil from Platteville, Colorado to Cushing, Oklahoma (the “White Cliffs Pipeline”); and

 

  ¡

a 50% ownership interest in Glass Mountain Pipeline, LLC, which owns a 215-mile crude oil pipeline in western and north central Oklahoma.

 

   

Crude Facilities operates crude oil storage and terminal businesses in the U.S. Crude Facilities assets include:

 

  ¡

approximately 7.6 million barrels of crude oil storage capacity in Cushing, Oklahoma, of which 6.25 million barrels are leased to customers and 1.35 million barrels are used for crude oil operations and marketing activities; and

 

  ¡

a 30-lane crude oil truck unloading facility with 350,000 barrels of associated storage capacity in Platteville, Colorado that connects to the origination point of the White Cliffs Pipeline.

 

   

Crude Supply and Logistics operates a crude oil marketing business that utilizes our Crude Transportation and Crude Facilities assets for marketing purposes. Additionally, Crude Supply and Logistics’ assets include:

 

  ¡

approximately 61,800 barrels of crude oil storage capacity in Trenton and Stanley, North Dakota.

 

   

SemGas provides natural gas gathering and processing services in the U.S. and owns and operates gathering systems and four processing plants with 595 million cubic feet per day of capacity.

 

   

SemCAMS provides natural gas gathering and processing services in Alberta, Canada and owns working interests in, and operates, four natural gas processing plants with a combined operating capacity of 695 million cubic feet per day.

 

   

SemLogistics provides refined product and crude oil storage services in the U.K. and owns a facility in Wales that has multi-product storage capacity of approximately 8.7 million barrels.

 

   

SemMexico purchases, produces, stores, and distributes liquid asphalt cement products in Mexico and operates an in-country network of twelve asphalt cement terminals and modification facilities and two marine terminals. We are currently evaluating a possible sale of this business.

 

   

SemStream owned 4,652,568 common units representing limited partner interests in NGL Energy Partners LP (“NGL Energy”) (NYSE: NGL) and an 11.78% interest in the general partner of NGL Energy. On April 27, 2016, we sold all of our NGL Energy limited partner units.

Pending Transaction with our Subsidiary Rose Rock

On May 30, 2016, we entered into a merger agreement with Rose Rock, pursuant to which we will acquire all of the outstanding common units of Rose Rock not already owned by us in an all stock-for-unit transaction at a ratio of 0.8136 SemGroup shares of Class A common stock per Rose Rock common unit. We expect to issue approximately 13.1 million shares of Class A common stock in connection with the closing of the merger based on the number of common units of Rose Rock not owned by us that were outstanding as of March 31, 2016. In addition, if the merger is consummated, we expect to become a guarantor of, or otherwise assume, an aggregate of $750 million of outstanding 5.625% senior unsecured notes of Rose Rock. We manage and operate Rose Rock through our ownership of Rose Rock’s general partner, and our consolidated financial statements include the accounts of Rose Rock.

 



 

S-2


Table of Contents

Completion of the merger is subject to the approval by our stockholders and the common unitholders of Rose Rock. We own approximately 56.2% of the Rose Rock common units, which is sufficient to approve the transaction on behalf of the holders of Rose Rock common units. Completion of the merger is also conditioned upon, among other things, (i) the effectiveness of a registration statement on Form S-4 with respect to the issuance by SemGroup of its shares of Class A common stock as the merger consideration and (ii) the approval of the listing on the New York Stock Exchange, subject to official notice of issuance, of such shares. Further, the consummation of the merger requires a waiver or amendment of certain provisions of our credit agreement and Rose Rock’s credit agreement, and we expect to amend and consolidate the credit agreements in connection with the closing of the merger.

Pursuant to the terms of the merger agreement, we have agreed (i) to cause a SemGroup stockholder meeting to be held to approve the issuance by us of the shares of Class A common stock as the merger consideration and (ii) to recommend to our stockholders the approval of the issuance of such shares. However, our Board of Directors may, subject to certain conditions, change its recommendation in favor of approval of the issuance of such common shares if it determines in good faith that failure to take such action would be reasonably likely to be inconsistent with its duties under applicable law or in connection with the receipt of a superior proposal; provided, however, that our Board of Directors must cause the stockholder meeting to be held to approve the issuance of the shares unless our Board has changed its recommendation in favor of such issuance in connection with a superior proposal.

The merger agreement contains provisions granting both us and Rose Rock the right to terminate the merger agreement for certain reasons, including, among others, if:

 

   

the merger is not completed on or before December 31, 2016;

 

   

any governmental authority has issued an order, decree or ruling or taken any other action (including the enactment of any statute, rule, regulation, decree or executive order) enjoining or prohibiting consummation of the merger; or

 

   

under certain conditions, there has been a material breach of any of the representations, warranties, covenants or agreements set forth in the merger agreement by a party to the merger agreement that is not cured by December 31, 2016.

The merger agreement provides for certain termination rights for Rose Rock. The merger agreement provides that upon termination of the merger agreement (i) in connection with the failure of the stockholders of SemGroup to approve the issuance of the common shares as the merger consideration, SemGroup shall pay to Rose Rock any and all of Rose Rock’s out-of-pocket expenses in an amount up to $3.8 million and (ii) in connection with a change by our Board of its recommendation in favor of approval of the issuance of the common shares under certain circumstances, SemGroup shall pay to Rose Rock a termination fee in the amount of $15.5 million.

Upon completion of the merger transaction, all of the outstanding common units of Rose Rock will be owned by us. Subject to customary approvals and conditions, we expect the merger to close in the third quarter of 2016.

We expect that the merger will provide us with immediate and long-term benefits. For example, we expect that the merger will:

 

   

be immediately accretive to SemGroup stockholders;

 

   

simplify our corporate capital structure and improve our cost of capital and our capital market access;

 

   

be viewed ratings positive by the ratings agencies; and

 

   

provide increased financial flexibility for execution of our strategic growth plan.

Risk Factors

Investing in our Class A common stock involves risks. You should consider the factors described under “Risk Factors” beginning on page S-6 of this prospectus supplement and the other risk factors incorporated by reference into this prospectus supplement and accompanying prospectus.

The number of shares of our Class A common stock outstanding after this offering is based on approximately 44,188,475 shares outstanding as of May 31, 2016 and excludes:

S-5


Table of Contents

RISK FACTORS

An investment in our Class A common stock involves risk. You should carefully read and consider the risks described below as well as the risk factors included in Item 1A. “Risk Factors” in our Annual report on Form 10-K for the year ended December 31, 2015, together with all of the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus. If any of these risks were to occur, our business, results of operations and financial condition could be materially adversely affected. As a result, the trading price of our Class A common stock may decline, and you might lose part or all of your investment.

Risks Related to our Pending Transaction with Rose Rock

Our pending transaction with Rose Rock may not close when expected, or at all.

The consummation of our merger with Rose Rock is subject to the approval of the issuance of shares of our Class A common stock pursuant to the merger agreement by our stockholders and the satisfaction of other customary closing conditions. If these conditions to closing are not satisfied or waived, if waivable, the merger with Rose Rock will not be consummated. Further, the consummation of the merger requires a waiver or amendment of certain provisions of our credit agreement and Rose Rock’s credit agreement. Although we expect to amend and consolidate the credit agreements to permit the merger, if the lenders do not consent and we cannot refinance the credit agreements, then we will not be able to consummate the merger. Additionally, there is no assurance that we will complete the merger in the time frame that we anticipate or under the terms set forth in the merger agreement, or at all. The closing of this offering is not conditioned on, and will be consummated before, the closing of the pending merger. Accordingly, if you choose to purchase our shares of Class A common stock, you should be willing to do so whether or not we complete the Rose Rock merger.

If our pending transaction with Rose Rock is consummated, we may not realize the benefits we expect.

We entered into the merger agreement with Rose Rock because we believe that the merger will be, among other things, immediately accretive to SemGroup stockholders, simplify our corporate capital structure and improve our cost of capital and our capital market access and provide increased financial flexibility for execution of our strategic growth plan. However, our assessments and expectations regarding these anticipated benefits of the merger may prove to be incorrect. Accordingly, there can be no assurance we will realize the anticipated benefits of our merger with Rose Rock.

Risks Related To Our Class A Common Stock

The market price of our Class A common stock may experience significant price and volume fluctuations.

The market price of our Class A common stock may change significantly in response to various factors and events beyond our control, including the following:

 

   

the risk factors described and incorporated by reference in this prospectus supplement;

 

   

our operating and financial results differing from that expected by securities analysts and investors;

 

   

changes in securities analysts’ estimates of our future financial performance and the future financial performance of our competitors;

 

   

the financial performance and stock performance of our competitors or companies in our industry generally;

 

   

changes in accounting standards, policies, interpretations or principles;

 

   

changes in laws or regulations which adversely affect our industry or us;

 

S-6


Table of Contents
   

general conditions in our customers’ industries; and

 

   

general economic conditions and conditions in the securities markets.

Volatility of our Class A common stock may make it difficult for you to resell shares of our Class A common stock when you desire or at attractive prices.

Holders of our Class A common stock may not receive dividends in the amount identified in guidance or any dividends.

We may not have sufficient cash each quarter to pay dividends or maintain current or expected levels of dividends. The actual amount of cash we pay out in dividends may fluctuate from quarter to quarter and will depend on various factors, some of which are beyond our control, including:

 

   

the amount of cash that our subsidiaries distribute to us;

 

   

the amount of cash we generate from our operations, our working capital needs, our level of capital expenditures and our ability to borrow;

 

   

the restrictions contained in our indentures and credit agreements and our debt service requirements; and

 

   

the cost of acquisitions, if any.

A failure either to pay dividends or to pay dividends at expected levels could result in a loss of investor confidence, reputational damage and a decrease in the market price of our Class A common stock.

Future sales or issuances of shares of our Class A common stock may adversely affect our stock price.

The future sale or issuance of a substantial number of shares of our Class A common stock in the public market or otherwise, or the perception that such sales or issuances could occur, may depress the market price of our Class A common stock. Sales or issuances of a substantial number of shares of our Class A common stock in the public market could occur at any time. These sales or issuances, or the possibility that these sales or issuances may occur, may also impair our ability to raise capital through the sale of additional equity securities.

Table of Contents

USE OF PROCEEDS

We estimate that the net proceeds from the sale of our Class A common stock in this offering will be approximately $         million (approximately $         million if the underwriter’s option is exercised in full), after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use all of the net proceeds from this offering for working capital and general corporate purposes, including to pay down our revolving credit facility and for future capital expenditures. The aggregate principal amount of borrowings outstanding under our revolving credit facility at March 31, 2016 was $70.0 million. Outstanding borrowings under our revolving credit facility were used primarily to fund construction costs related to our Maurepas pipeline project. The weighted average interest rate on the revolving credit facility was 3.69% as of March 31, 2016. The revolving credit facility matures on December 11, 2018.

While we have identified the expected uses for the net proceeds of this offering, we have not fully determined the specific amounts we plan to spend on the particular uses noted above or the timing of these expenses. As a result, our management will have broad discretion in utilizing the net proceeds from this offering, and investors will be relying on the judgment of our management with regard to the use of these net proceeds.

Affiliates of Barclays Capital Inc. are lenders under our revolving credit facility and accordingly will receive a portion of the proceeds of this offering through any repayment of indebtedness under the facility. See “Underwriting—Relationships.”

DIVIDEND POLICY

In January 2013, we announced our intention to pay a quarterly cash dividend to common stockholders beginning in the second quarter of 2013. We had not paid any cash dividends on our Class A common stock prior to the second quarter of 2013. We intend to pay our dividends from our “cash available for dividends,” which is based on adjusted EBITDA, adjusted to exclude the earnings of our subsidiary, Rose Rock, cash income taxes, cash interest expense, maintenance capital expenditures and any cash reserves established by our management and to include cash distributions received from Rose Rock. Cash reserves are established by our management to provide for the proper conduct of our business, including reserves for future capital expenditures and for anticipated future credit needs.

Our credit agreement allows payments or distributions as long as we (i) are in compliance on a pro forma basis with our financial covenants and (ii) demonstrate a minimum liquidity of $50 million.

The following table sets forth the dividends paid per share of Class A common stock in the quarter indicated.

UNDERWRITING

Barclays Capital Inc. is acting as sole underwriter of this offering. Under the terms of an underwriting agreement, which we will file as an exhibit to our current report on Form 8-K and incorporate by reference in this prospectus supplement and the accompanying prospectus, the underwriter has agreed to purchase from us 5,000,000 shares at a public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement.

The underwriting agreement provides that the underwriter’s obligation to purchase the shares depends on the satisfaction of the conditions contained in the underwriting agreement, including:

 

   

the obligation to purchase all of the shares offered hereby (other than those shares covered by its option to purchase additional shares as described below), if any of the shares are purchased;

 

   

the representations and warranties made by us to the underwriter are true;

 

   

there is no material adverse change in our business or in the financial markets; and

 

   

our delivery of customary closing documents to the underwriter.

Commissions and Expenses

The following table summarizes the underwriting discounts and commissions we will pay to the underwriter. These amounts are shown assuming both no exercise and full exercise of the underwriter’s option to purchase additional shares. The underwriting fee is the difference between the initial price to the public and the amount the underwriter pays to us for the shares.

 

     No Exercise      Full Exercise  

Per share

   $                    $                

Total

   $         $     

The underwriter has advised us that it proposes to offer the shares directly to the public at the public offering price on the cover of this prospectus supplement and to selected dealers, which may include the underwriter, at such offering price less a selling concession not in excess of $ per share. Sales of shares made outside of the United States may be made by affiliates of the underwriter.

The expenses of the offering that are payable by us are estimated to be approximately $0.4 million (excluding underwriting discounts and commissions).

Option to Purchase Additional Shares

We have granted the underwriter an option exercisable for 30 days after the date of this prospectus supplement, to purchase, from time to time, in whole or in part, up to an aggregate of 750,000 shares at the public offering price less underwriting discounts and commissions. This option may be exercised if the underwriter sells more than 5,000,000 shares in connection with this offering.

Lock-Up Agreements

We and our directors and executive officers have agreed that, for a period of 60 days after the date of this prospectus supplement, we and they will not directly or indirectly, without the prior written consent of Barclays Capital Inc., (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 (including, without limitation, shares that may be deemed to be beneficially owned by us or them in accordance with the rules and regulations of the SEC and shares that may be issued upon exercise of any options

Table of Contents

or warrants) or securities convertible into or exercisable or exchangeable for shares, other than certain permitted transfers and issuances and grants of options, (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 shares, (3) file or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares or securities convertible, exercisable or exchangeable into shares or any of our other securities, or (4) publicly disclose the intention to do any of the foregoing.

These restrictions do not apply to, among other things:

 

   

the sale of shares to the underwriter pursuant to the underwriting agreement;

 

   

the issuance by us of additional awards or shares under currently outstanding employee benefit plans, qualified stock option plans or other employee compensation plans existing on the date of this prospectus;

 

   

the issuance of options, warrants or rights outstanding on the date of this prospectus;

 

   

the filing of one or more registration statements on Form S-8 relating to any employee benefit plan in effect on the date of this prospectus;

 

   

the filing of a registration statement on Form S-4 relating to the merger with Rose Rock; or

 

   

certain other exceptions.

Barclays Capital Inc., in its sole discretion, may release the shares and other securities subject to the lock-up agreements described above in whole or in part at any time with or without notice. When determining whether or not to release shares and other securities from lock-up agreements, Barclays Capital Inc. will consider, among other factors, the holder’s reasons for requesting the release, the number of shares and other securities for which the release is being requested and market conditions at the time.

Indemnification

We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriter may be required to make for these liabilities.

Stabilization, Short Positions and Penalty Bids

The underwriter may engage in stabilizing transactions, short sales and purchases to cover positions created by short sales, and penalty bids or purchases for the purpose of pegging, fixing or maintaining the price of the shares, in accordance with Regulation M under the Securities Exchange Act of 1934:

 

   

Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

 

   

A short position involves a sale by the underwriter of shares in excess of the number of shares the underwriter is obligated to purchase in the offering, which creates the syndicate short position. This short position may be either a covered short position or a naked short position. In a covered short position, the number of shares involved in the sales made by the underwriter in excess of the number of shares it is obligated to purchase is not greater than the number of shares that it may purchase by exercising its option to purchase additional shares. In a naked short position, the number of shares involved is greater than the number of shares in its option to purchase additional shares. The underwriter may close out any short position by either exercising its option to purchase additional shares and/or purchasing shares in the open market. In determining the source of shares to close out the short position, the underwriter will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which it may purchase shares through its option to purchase additional shares. A naked short position is more likely to be created if the underwriter is concerned that

 

S-13


Table of Contents
 

there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

 

   

Syndicate covering transactions involve purchases of the shares in the open market after the distribution has been completed in order to cover syndicate short positions.

 

   

Penalty bids permit the representative to reclaim a selling concession from a syndicate member when the shares originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our shares of Class A common stock or preventing or retarding a decline in the market price of the shares. As a result, the price of the shares may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the New York Stock Exchange or otherwise and, if commenced, may be discontinued at any time.

Neither we nor the underwriter makes 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 shares. In addition, neither we nor the underwriter makes any representation that the underwriter will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

Electronic Distribution

A prospectus supplement and the accompanying prospectus in electronic format may be made available on the Internet sites or through other online services maintained by the underwriter and/or selling group members participating in this offering, or by their affiliates. In those cases, prospective investors may view offering terms online and, depending upon the particular underwriter or selling group member, prospective investors may be allowed to place orders online. The underwriter may agree with us to allocate a specific number of shares for sale to online brokerage account holders.

Other than the prospectus supplement and the accompanying prospectus in electronic format, the information on any underwriter’s or selling group member’s web site and any information contained in any other web site maintained by an underwriter or selling group member is not part of the prospectus supplement and the accompanying prospectus or the registration statement of which this prospectus supplement and the accompanying prospectus form a part, has not been approved and/or endorsed by us or any underwriter or selling group member in its capacity as underwriter or selling group member and should not be relied upon by investors.

Stamp Taxes

If you purchase shares offered in this prospectus supplement and the accompanying prospectus, you may be required to pay stamp taxes and other charges under the laws and practices of the country of purchase, in addition to the offering price listed on the cover page of this prospectus supplement and the accompanying prospectus.

Relationships

They have received, and expect to receive, customary compensation and expense reimbursement for these services.

No representation or warranty is hereby made as to the tax consequences to a resident, or deemed resident, of Canada of an investment in the Securities or with respect to the eligibility of the Securities for investment by such investor under relevant Canadian federal and provincial legislation and regulations.

Rights of Action for Damages or Rescission

Securities legislation in certain of the Canadian jurisdictions provides certain purchasers of securities pursuant to an offering memorandum, including where the distribution involves an “eligible foreign security” as such term is defined in Ontario Securities Commission Rule 45-501 Ontario Prospectus and Registration Exemptions and in Multilateral Instrument 45-107 Listing Representation and Statutory Rights of Action Disclosure Exemptions, as applicable, with a remedy for damages or rescission, or both, in addition to any other rights they may have at law, where the offering memorandum, or other offering document that constitutes an offering memorandum, and any amendment thereto, contains a “misrepresentation” as defined under applicable Canadian securities laws. These remedies, or notice with respect to these remedies, must be exercised or delivered, as the case may be, by the purchaser within the time limits prescribed under, and are subject to limitations and defences under, applicable Canadian securities legislation. In addition, these remedies are in addition to and without derogation from any other right or remedy available at law to the investor.

RATIO OF EARNINGS TO FIXED CHARGES

The table below shows our ratio of earnings to fixed charges for the periods indicated. For purposes of this computation, “earnings” include pre-tax income from continuing operations before adjustment for non-controlling interests in consolidated subsidiaries or income or loss from equity investees (including gain on issuance of common units by equity method investee), fixed charges, amortization of capitalized interest, distributed income of equity investees and our share of pre-tax losses of equity investees for which charges arising from guarantees are included in fixed charges, less interest capitalized, preference security dividend requirements of consolidated subsidiaries and the minority interest in pre-tax income of subsidiaries that have not incurred fixed charges. “Fixed charges” include interest (whether expensed or capitalized), amortized premiums, discounts and capitalized expenses related to indebtedness, an estimate of the interest within rental expense and preference security dividend requirements of consolidated subsidiaries. No shares of preferred stock were outstanding during the periods indicated. Accordingly, the ratio of earnings to combined fixed charges and preferred stock dividends is the same as the ratio of earnings to fixed charges for each such period in the table below.

DESCRIPTION OF SENIOR DEBT SECURITIES

General

The following description applies to the senior debt securities offered by this prospectus. Unless otherwise indicated in the applicable prospectus supplement, the senior debt securities will be direct, unsecured obligations of SemGroup and will rank on a parity with all of our outstanding unsecured senior indebtedness. The senior debt securities may be issued in one or more series. The senior debt securities will be issued under an indenture between us and the trustee specified in the applicable prospectus supplement.

The statements under this caption are brief summaries of the provisions contained in the indenture, do not claim to be complete and are qualified in their entirety by reference to the indenture, a copy of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Whenever defined terms are used but not defined in this prospectus, those terms have the meanings given to them in the indenture.

The following describes the general terms and provisions of the senior debt securities to which any prospectus supplement may relate. The particular terms of any senior debt security and the extent, if any, to which these general provisions may apply to the senior debt securities will be described in the prospectus supplement relating to the senior debt securities.

 

5


Table of Contents

The indenture does not limit the aggregate principal amount of senior debt securities which may be issued under it. Rather, the indenture provides that senior debt securities of any series may be issued under it up to the aggregate principal amount which we may authorize from time to time. Senior debt securities may be denominated in any currency or currency unit we designate. The indenture does not limit or otherwise restrict the amount of other debt which we may incur or the other securities which we may issue.

Senior debt securities of a series may be issuable in registered form without coupons, which we refer to as “registered securities,” or in the form of one or more global securities in registered form, which we refer to as “global securities.”

You must review the prospectus supplement for a description of the following terms, where applicable, of each series of senior debt securities for which this prospectus is being delivered:

 

    the title of the senior debt securities;

 

    the limit, if any, on the aggregate principal amount or aggregate initial public offering price of the senior debt securities;

 

    the priority of payment of the senior debt securities;

 

    the price or prices, which may be expressed as a percentage of the aggregate principal amount, at which the senior debt securities will be issued;

 

    the date or dates on which the principal of the senior debt securities will be payable;

 

    the interest rate or rates, which may be fixed or variable, for the senior debt securities, if any, or the method of determining the same;

 

    the date or dates from which interest, if any, on the senior debt securities will accrue, the date or dates on which interest, if any, will be payable, the date or dates on which payment of interest, if any, will commence and the regular record dates for the interest payment dates;

 

    the extent to which any of the senior debt securities will be issuable in temporary or permanent global form, or the manner in which any interest payable on a temporary or permanent global senior debt security will be paid;

 

    each office or agency where the senior debt securities may be presented for registration of transfer or exchange;

 

    the place or places where the principal of and any premium and interest on the senior debt securities will be payable;

 

    the date or dates, if any, after which the senior debt securities may be redeemed or purchased in whole or in part, (1) at our option or (2) mandatorily pursuant to any sinking, purchase or similar fund or (3) at the option of the holder, and the redemption or repayment price or prices;

 

    the terms, if any, upon which the senior debt securities may be convertible into or exchanged for any other kind of our securities or indebtedness and the terms and conditions upon which the conversion or exchange would be made, including the initial conversion or exchange price or rate, the conversion period and any other additional provisions;

 

    the authorized denomination or denominations for the senior debt securities;

 

    the currency, currencies or units based on or related to currencies for which the senior debt securities may be purchased and the currency, currencies or currency units in which the principal of and any premium and interest on the senior debt securities may be payable;

 

    any index used to determine the amount of payments of principal of and any premium and interest on the senior debt securities;

 

6


Table of Contents
    the payment of any additional amounts with respect to the senior debt securities;

 

    whether any of the senior debt securities will be issued with original issue discount;

 

    information with respect to book-entry procedures, if any;

 

    any additional covenants or events of default not currently included in the indenture relating to the senior debt securities; and

 

    any other terms of the senior debt securities not inconsistent with the provisions of the indenture.

If any of the senior debt securities are sold for one or more foreign currencies or foreign currency units or if the principal of or any premium or interest on any series of senior debt securities is payable in one or more foreign currencies or foreign currency units, the restrictions, elections, tax consequences, specific terms and other information with respect to that issue of senior debt securities and those currencies or currency units will be described in the applicable prospectus supplement.

A judgment for money damages by courts in the U.S., including a money judgment based on an obligation expressed in a foreign currency, will ordinarily be rendered only in U.S. dollars. New York statutory law provides that a court shall render a judgment or decree in the foreign currency of the underlying obligation and that the judgment or decree shall be converted into U.S. dollars at the exchange rate prevailing on the date of entry of the judgment or decree.

Senior debt securities may be issued as original issue discount senior debt securities, which bear no interest or interest at a rate which at the time of issuance is below market rates, to be sold at a substantial discount below their stated principal amount due at the stated maturity of the senior debt securities. There may be no periodic payments of interest on original issue discount securities. In the event of an acceleration of the maturity of any original issue discount security, the amount payable to the holder of the original issue discount security upon acceleration will be determined in accordance with the prospectus supplement, the terms of the security and the indenture, but will be an amount less than the amount payable at the maturity of the principal of the original issue discount security.

If the senior debt securities are issued with “original issue discount” within the meaning of the Internal Revenue Code of 1986, as amended, then a holder of those senior debt securities will be required under the Internal Revenue Code to include original issue discount in ordinary income for federal income tax purposes as it accrues, in accordance with a constant interest method that takes into account the compounding of interest, in advance of receipt of cash attributable to that income. Generally, the total amount of original issue discount on a senior debt security will be the excess of the stated redemption price at maturity of the security over the price at which the security is sold to the public. To the extent a holder of a senior debt security receives a payment (at the time of acceleration of maturity, for example) that represents payment of original issue discount already included by the holder in ordinary income or reflected in the holder’s tax basis in the security, that holder generally will not be required to include the payment in income. The specific terms of any senior debt securities that are issued with original issue discount and the application of the original discount rules under the Internal Revenue Code to those securities will be described in a prospectus supplement for those securities.

Registration and Transfer

Unless otherwise indicated in the applicable prospectus supplement, senior debt securities will be issued only as registered securities. Senior debt securities issued as registered securities will not have interest coupons.

Registered securities (other than a global security) may be presented for transfer, with the form of transfer endorsed thereon duly executed, or exchanged for other senior debt securities of the same series at the office of the security registrar specified in the indenture. Transfer or exchange will be made without service charge, but we may require payment of any taxes or other governmental charges.

Table of Contents

Book-Entry Senior Debt Securities

Senior debt securities of a series may be issued in whole or in part in the form of one or more global securities. Each global security will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement. Global securities will be issued in registered form and in either temporary or permanent form. Until exchanged in whole or in part for the individual securities which it represents, a global security may not be transferred except as a whole by the depositary for the global security to a nominee of the depositary or by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any nominee to a successor depositary or any nominee of the successor. The specific terms of the depositary arrangement for a series of senior debt securities will be described in the applicable prospectus supplement.

Payment and Paying Agents

Unless otherwise indicated in an applicable prospectus supplement, payment of principal of and any premium and interest on registered securities will be made at the office of such paying agent or paying agents as we may designate from time to time. In addition, at our option, payment of any interest may be made by:

 

    check mailed to the address of the person entitled to the payment at the address in the applicable security register; or

 

    wire transfer to an account maintained by the person entitled to the payment as specified in the applicable security register.

Unless otherwise indicated in an applicable prospectus supplement, payment of any installment of interest on registered securities will be made to the person in whose name the senior debt security is registered at the close of business on the regular record date for the payment.

Consolidation, Merger or Sale of Assets

The indenture relating to the senior debt securities provides that we may, without the consent of the holders of any of the senior debt securities outstanding under the indenture, consolidate with, merge into or transfer our assets substantially as an entirety to any person, provided that:

 

    any successor assumes our obligations on the senior debt securities and under the indenture; and

 

    after giving effect to the consolidation, merger or transfer, no event of default (as defined in the indenture) will have happened and be continuing.

Any consolidation, merger or transfer of assets substantially as an entirety, which meets the conditions described above, would not create an event of default which would entitle holders of the senior debt securities, or the trustee acting on their behalf, to take any of the actions described below under “—Events of Default, Waivers, Etc.”

Leveraged and Other Transactions

The indenture and the senior debt securities do not contain provisions which would protect holders of the senior debt securities in the event we engaged in a highly leveraged or other transaction which could adversely affect the holders of senior debt securities.

Modification of the Indenture

The indenture provides that, with the consent of the holders of a majority in aggregate principal amount of the outstanding senior debt securities of each affected series, modifications and alterations of the indenture may be made which affect the rights of the holders of the senior debt securities. However, no modification or alteration may be made without the consent of the holder of each senior debt security affected which would, among other things,

 

    modify the terms of payment of principal of or any premium or interest on the senior debt securities; or

 

8


Table of Contents
    reduce the percentage in principal amount of outstanding senior debt securities required to modify or alter the indenture.

Events of Default, Waivers, Etc.

An “event of default” with respect to senior debt securities of any series is defined in the indenture to include:

 

  (1) default in the payment of principal of or any premium on any of the outstanding senior debt securities of that series when due;

 

  (2) default in the payment of interest on any of the outstanding senior debt securities of that series when due and continuance of such default for 30 days;

 

  (3) default in the performance of any of our other covenants in the indenture with respect to the senior debt securities of that series and continuance of such default for 60 days after written notice;

 

  (4) certain events of bankruptcy, insolvency or reorganization relating to us; and

 

  (5) any other event that may be specified in a prospectus supplement with respect to any series of senior debt securities.

If an event of default with respect to any series of outstanding senior debt securities occurs and is continuing, either the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding senior debt securities of that series may declare the principal amount (or with respect to original issue discount securities, the portion of the principal amount as may be specified in the terms of that series) of all senior debt securities of that series to be immediately due and payable. At any time after such a declaration of acceleration and before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in aggregate principal amount of the outstanding senior debt securities of any series may rescind and annul the declaration of acceleration and its consequences, but only if all events of default with respect to senior debt securities of such series have been remedied and all payments due, other than those due as a result of acceleration, have been made.

If an event of default occurs and is continuing, the trustee may, in its discretion, and at the written request to the trustee of holders of not less than 25% in aggregate principal amount of the outstanding senior debt securities of any series and upon reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request and subject to certain other conditions set forth in the indenture will, proceed to protect the rights of the holders of all the senior debt securities of that series. Prior to acceleration of maturity of the outstanding senior debt securities of any series, the holders of not less than a majority in aggregate principal amount of the senior debt securities may, on behalf of all of the holders of the senior debt securities, waive any past default under the indenture except a default in the payment of principal of or any premium or interest on the senior debt securities of that series, a failure by us to convert any senior debt security into shares of our Class A common stock (to the extent such right is applicable) or in respect of a covenant or provision of the indenture which, pursuant to the indenture, cannot be waived without the consent of each holder of outstanding senior debt securities.

The indenture provides that upon the occurrence of an event of default specified in clauses (1) or (2) of the first paragraph in this subsection, we will, upon demand of the trustee, pay to it, for the benefit of the holders of any senior debt securities, the whole amount then due and payable on the affected senior debt securities for principal, premium, if any, and interest, if any. The indenture further provides that if we fail to pay such amount upon demand, the trustee may, among other things, institute a judicial proceeding for the collection of those amounts.

Table of Contents

The indenture also provides that notwithstanding any of its other provisions, the holder of any senior debt security of any series will have the right to institute suit for the enforcement of any payment of principal of or any premium or interest on the senior debt securities when due and that such right will not be impaired without the consent of that holder.

We are required to file annually with the trustee a written statement of our officers as to the existence or non-existence of defaults under the indenture or the senior debt securities.

Satisfaction and Discharge

The indenture provides, among other things, that when all senior debt securities not previously delivered to the trustee for cancellation (1) have become due and payable or (2) will become due and payable at their stated maturity within one year, we may deposit with the trustee funds, in trust, for the purpose and in an amount sufficient to pay and discharge the entire indebtedness on the senior debt securities not previously delivered to the trustee for cancellation. Those funds will include all principal, premium, if any, and interest, if any, to the date of the deposit or to the stated maturity, as applicable. Upon such deposit, the indenture will cease to be of further effect except as to our obligations to pay all other sums due under the indenture and to provide the officers’ certificates and opinions of counsel required under the indenture. At such time we will be deemed to have satisfied and discharged the indenture.

Governing Law

The indenture and the senior debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

Regarding the Trustee

Information concerning the trustee for a series of senior debt securities will be set forth in the prospectus supplement relating to that series of senior debt securities.

We may have normal banking relationships with the trustee in the ordinary course of business.

DESCRIPTION OF SUBORDINATED DEBT SECURITIES

General

The following description applies to the subordinated debt securities offered by this prospectus. Unless otherwise indicated in the applicable prospectus supplement, the subordinated debt securities will be unsecured, subordinated obligations of SemGroup. The subordinated debt securities may be issued in one or more series. The subordinated debt securities will be issued under an indenture between us and the trustee specified in the applicable prospectus supplement.

The statements under this caption are brief summaries of the provisions contained in the indenture, do not claim to be complete and are qualified in their entirety by reference to the indenture, a copy of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Whenever defined terms are used but not defined in this prospectus, those terms have the meanings given to them in the indenture.

The following describes the general terms and provisions of the subordinated debt securities to which any prospectus supplement may relate. The particular terms of any subordinated debt security and the extent, if any,

 

10


Table of Contents

to which these general provisions may apply to the subordinated debt securities will be described in the prospectus supplement relating to the subordinated debt securities.

The indenture does not limit the aggregate principal amount of subordinated debt securities which may be issued under it. Rather, the indenture provides that subordinated debt securities of any series may be issued under it up to the aggregate principal amount which we may authorize from time to time. Subordinated debt securities may be denominated in any currency or currency unit we designate. The indenture does not limit or otherwise restrict the amount of other debt which we may incur or the other securities which we may issue.

Subordinated debt securities of a series may be issuable in the form of registered securities or global securities.

You must review the prospectus supplement for a description of the following terms, where applicable, of each series of subordinated debt securities for which this prospectus is being delivered:

 

    the title of the subordinated debt securities;

 

    the limit, if any, on the aggregate principal amount or aggregate initial public offering price of the subordinated debt securities;

 

    the priority of payment of the subordinated debt securities;

 

    the price or prices, which may be expressed as a percentage of the aggregate principal amount, at which the subordinated debt securities will be issued;

 

    the date or dates on which the principal of the subordinated debt securities will be payable;

 

    the interest rate or rates, which may be fixed or variable, for the subordinated debt securities, if any, or the method of determining the same;

 

    the date or dates from which interest, if any, on the subordinated debt securities will accrue, the date or dates on which interest, if any, will be payable, the date or dates on which payment of interest, if any, will commence and the regular record dates for the interest payment dates;

 

    the extent to which any of the subordinated debt securities will be issuable in temporary or permanent global form, or the manner in which any interest payable on a temporary or permanent global subordinated debt security will be paid;

 

    each office or agency where the subordinated debt securities may be presented for registration of transfer or exchange;

 

    the place or places where the principal of and any premium and interest on the subordinated debt securities will be payable;

 

    the date or dates, if any, after which the subordinated debt securities may be redeemed or purchased in whole or in part, (1) at our option or (2) mandatorily pursuant to any sinking, purchase or similar fund or (3) at the option of the holder, and the redemption or repayment price or prices;

 

    the terms, if any, upon which the subordinated debt securities may be convertible into or exchanged for any other kind of our securities or indebtedness and the terms and conditions upon which the conversion or exchange would be made, including the initial conversion or exchange price or rate, the conversion period and any other additional provisions;

 

    the authorized denomination or denominations for the subordinated debt securities;

 

    the currency, currencies or units based on or related to currencies for which the subordinated debt securities may be purchased and the currency, currencies or currency units in which the principal of and any premium and interest on the subordinated debt securities may be payable;

 

11


Table of Contents
    any index used to determine the amount of payments of principal of and any premium and interest on the subordinated debt securities;

 

    the payment of any additional amounts with respect to the subordinated debt securities;

 

    whether any of the subordinated debt securities will be issued with original issue discount;

 

    information with respect to book-entry procedures, if any;

 

    the terms of subordination;

 

    any additional covenants or events of default not currently included in the indenture relating to the subordinated debt securities; and

 

    any other terms of the subordinated debt securities not inconsistent with the provisions of the indenture.

If any of the subordinated debt securities are sold for one or more foreign currencies or foreign currency units or if the principal of or any premium or interest on any series of subordinated debt securities is payable in one or more foreign currencies or foreign currency units, the restrictions, elections, tax consequences, specific terms and other information with respect to that issue of subordinated debt securities and those currencies or currency units will be described in the applicable prospectus supplement.

A judgment for money damages by courts in the U.S., including a money judgment based on an obligation expressed in a foreign currency, will ordinarily be rendered only in U.S. dollars. New York statutory law provides that a court shall render a judgment or decree in the foreign currency of the underlying obligation and that the judgment or decree shall be converted into U.S. dollars at the exchange rate prevailing on the date of entry of the judgment or decree.

Subordinated debt securities may be issued as original issue discount securities, to be sold at a substantial discount below their stated principal amount due at the stated maturity of the subordinated debt securities. There may be no periodic payments of interest on original issue discount securities. In the event of an acceleration of the maturity of any original issue discount security, the amount payable to the holder of the original issue discount security upon acceleration will be determined in accordance with the prospectus supplement, the terms of the security and the indenture, but will be an amount less than the amount payable at the maturity of the principal of the original issue discount security.

If the subordinated debt securities are issued with “original issue discount” within the meaning of the Internal Revenue Code of 1986, as amended, then a holder of those subordinated debt securities will be required under the Internal Revenue Code to include original issue discount in ordinary income for federal income tax purposes as it accrues, in accordance with a constant interest method that takes into account the compounding of interest, in advance of receipt of cash attributable to that income. Generally, the total amount of original issue discount on a subordinated debt security will be the excess of the stated redemption price at maturity of the security over the price at which the security is sold to the public. To the extent a holder of a subordinated debt security receives a payment (at the time of acceleration of maturity, for example) that represents payment of original issue discount already included by the holder in ordinary income or reflected in the holder’s tax basis in the security, that holder generally will not be required to include the payment in income. The specific terms of any subordinated debt securities that are issued with original issue discount and the application of the original discount rules under the Internal Revenue Code to those securities will be described in a prospectus supplement for those securities.

Registration and Transfer

Unless otherwise indicated in the applicable prospectus supplement, subordinated debt securities will be issued only as registered securities. Subordinated debt securities issued as registered securities will not have interest coupons.

 

12


Table of Contents

Registered securities (other than a global security) may be presented for transfer, with the form of transfer endorsed thereon duly executed, or exchanged for other subordinated debt securities of the same series at the office of the security registrar specified in the indenture. Transfer or exchange will be made without service charge, but we may require payment of any taxes or other governmental charges.

Book-Entry Subordinated Debt Securities

Subordinated debt securities of a series may be issued in whole or in part in the form of one or more global securities. Each global security will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement. Global securities will be issued in registered form and in either temporary or permanent form. Until exchanged in whole or in part for the individual securities which it represents, a global security may not be transferred except as a whole by the depositary for the global security to a nominee of the depositary or by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any nominee to a successor depositary or any nominee of the successor. The specific terms of the depositary arrangement for a series of subordinated debt securities will be described in the applicable prospectus supplement.

Payment and Paying Agents

Unless otherwise indicated in an applicable prospectus supplement, payment of principal of and any premium and interest on registered securities will be made at the office of such paying agent or paying agents as we may designate from time to time. In addition, at our option, payment of any interest may be made by:

 

    check mailed to the address of the person entitled to the payment at the address in the applicable security register; or

 

    wire transfer to an account maintained by the person entitled to the payment as specified in the applicable security register.

Unless otherwise indicated in an applicable prospectus supplement, payment of any installment of interest on registered securities will be made to the person in whose name the subordinated debt security is registered at the close of business on the regular record date for the payment.

Subordination

The subordinated debt securities will be subordinated and junior in right of payment to some of our other indebtedness (which may include senior indebtedness for money borrowed) to the extent described in the applicable prospectus supplement.

Consolidation, Merger or Sale of Assets

The indenture relating to the subordinated debt securities provides that we may, without the consent of the holders of any of the subordinated debt securities outstanding under the indenture, consolidate with, merge into or transfer our assets substantially as an entirety to any person, provided that:

 

    any successor assumes our obligations on the subordinated debt securities and under the indenture; and

 

    after giving effect to the consolidation, merger or transfer, no event of default (as defined in the indenture) will have happened and be continuing.

Any consolidation, merger or transfer of assets substantially as an entirety, which meets the conditions described above, would not create an event of default which would entitle holders of the subordinated debt securities, or the trustee acting on their behalf, to take any of the actions described below under “—Events of Default, Waivers, Etc.”

 

13


Table of Contents

Leveraged and Other Transactions

The indenture and the subordinated debt securities do not contain provisions which would protect holders of the subordinated debt securities in the event we engaged in a highly leveraged or other transaction which could adversely affect the holders of subordinated debt securities.

Modification of the Indenture

The indenture provides that, with the consent of the holders of a majority in aggregate principal amount of the outstanding subordinated debt securities of each affected series, modifications and alterations of the indenture may be made which affect the rights of the holders of the subordinated debt securities. However, no modification or alteration may be made without the consent of the holder of each subordinated debt security affected which would, among other things,

 

    modify the terms of payment of principal of or any premium or interest on the subordinated debt securities;

 

    adversely modify the subordination terms of the subordinated debt securities; or

 

    reduce the percentage in principal amount of outstanding subordinated debt securities required to modify or alter the indenture.

Events of Default, Waivers, Etc.

An “event of default” with respect to subordinated debt securities of any series is defined in the indenture to include:

 

  (1) default in the payment of principal of or any premium on any of the outstanding subordinated debt securities of that series when due;

 

  (2) default in the payment of interest on any of the outstanding subordinated debt securities of that series when due and continuance of such default for 30 days;

 

  (3) default in the performance of any of our other covenants in the indenture with respect to the subordinated debt securities of that series and continuance of such default for 60 days after written notice;

 

  (4) certain events of bankruptcy, insolvency or reorganization relating to us; and

 

  (5) any other event that may be specified in a prospectus supplement with respect to any series of subordinated debt securities.

If an event of default with respect to any series of outstanding subordinated debt securities occurs and is continuing, either the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding subordinated debt securities of that series may declare the principal amount (or with respect to original issue discount securities, the portion of the principal amount as may be specified in the terms of that series) of all subordinated debt securities of that series to be immediately due and payable. At any time after such a declaration of acceleration and before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in aggregate principal amount of the outstanding subordinated debt securities of any series may rescind and annul the declaration of acceleration and its consequences, but only if all events of default with respect to subordinated debt securities of such series have been remedied and all payments due, other than those due as a result of acceleration, have been made.

If an event of default occurs and is continuing, the trustee may, in its discretion, and at the written request to the trustee of holders of not less than 25% in aggregate principal amount of the outstanding subordinated debt securities of any series and upon reasonable indemnity against the costs, expenses and liabilities to be incurred in

 

14


Table of Contents

compliance with such request and subject to certain other conditions set forth in the indenture will, proceed to protect the rights of the holders of all the subordinated debt securities of that series. Prior to acceleration of maturity of the outstanding subordinated debt securities of any series, the holders of not less than a majority in aggregate principal amount of the subordinated debt securities may, on behalf of all of the holders of the subordinated debt securities, waive any past default under the indenture except a default in the payment of principal of or any premium or interest on the subordinated debt securities of that series, a failure by us on request to convert any subordinated debt security into shares of our Class A common stock (to the extent such right is applicable) or in respect of a covenant or provision of the indenture which, pursuant to the indenture, cannot be waived without the consent of each holder of outstanding subordinated debt securities.

The indenture provides that upon the occurrence of an event of default specified in clauses (1) or (2) of the first paragraph in this subsection, we will, upon demand of the trustee, pay to it, for the benefit of the holders of any subordinated debt securities, the whole amount then due and payable on the affected subordinated debt securities for principal, premium, if any, and interest, if any. The indenture further provides that if we fail to pay such amount upon demand, the trustee may, among other things, institute a judicial proceeding for the collection of those amounts.

The indenture also provides that notwithstanding any of its other provisions, the holder of any subordinated debt security of any series will have the right to institute suit for the enforcement of any payment of principal of or any premium or interest on the subordinated debt securities when due and that such right will not be impaired without the consent of that holder.

We are required to file annually with the trustee a written statement of our officers as to the existence or non-existence of defaults under the indenture or the subordinated debt securities.

Satisfaction and Discharge

The indenture provides, among other things, that when all subordinated debt securities not previously delivered to the trustee for cancellation (1) have become due and payable or (2) will become due and payable at their stated maturity within one year, we may deposit with the trustee funds, in trust, for the purpose and in an amount sufficient to pay and discharge the entire indebtedness on the subordinated debt securities not previously delivered to the trustee for cancellation. Those funds will include all principal, premium, if any, and interest, if any, to the date of the deposit or to the stated maturity, as applicable. Upon such deposit, the indenture will cease to be of further effect except as to our obligations to pay all other sums due under the indenture and to provide the officers’ certificates and opinions of counsel required under the indenture. At such time we will be deemed to have satisfied and discharged the indenture.

Governing Law

The indenture and the subordinated debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

Regarding the Trustee

Information concerning the trustee for a series of subordinated debt securities will be set forth in the prospectus supplement relating to that series of subordinated debt securities.

We may have normal banking relationships with the trustee in the ordinary course of business.

DESCRIPTION OF CAPITAL STOCK

General

We have the authority to issue 100,000,000 shares of common stock, which consist of 90,000,000 shares of Class A Common Stock, par value $0.01 per share (the “Class A Common Stock”), and 10,000,000 shares of

 

15


Table of Contents

Class B Common Stock, par value $0.01 per share (the “Class B Common Stock,” together with the Class A Common Stock, the “Class A and Class B Common Stock”). We are registering Class A Common Stock hereunder. We are not registering Class B Common Stock hereunder.

Common Stock

As of March 4, 2016, 43,961,629 shares of our Class A Common Stock were issued and outstanding and no shares of our Class B Common Stock were issued and outstanding. All of the outstanding shares of our Class A Common Stock are fully paid and nonassessable.

The Class A Common Stock and the Class B Common Stock are identical in all respects, except that the Class B Common Stock is not eligible for trading on a national securities exchange or market system.

Voting Rights

Holders of shares of Class A and Class B Common Stock are entitled to one vote per share on each matter on which the holders of our common stock are entitled to vote, including the election of directors. Holders of Class A and Class B Common Stock vote together as a single class. Holders of Class A and Class B Common Stock do not have cumulative voting rights with respect to the election of directors, meaning that the holders of a majority of the shares voting for the election of directors can elect all of the directors standing for election.

Dividend and Liquidation Rights

The holders of Class A and Class B Common Stock are entitled to receive ratably such dividends as may be declared by our Board of Directors from funds legally available. The terms of our current credit facility, however, restrict, to some extent, the payment of cash dividends on our common stock. In the event of a liquidation, dissolution, distribution of assets or other winding up of our company, the holders of the Class A and Class B Common Stock are entitled to share equally and ratably, share for share, in all assets remaining for distribution to stockholders.

Redemption and Preemptive Rights

Holders of Class A and Class B Common Stock have no redemption or preemptive rights.

Conversion Rights of Class B Common Stock

Each share of Class B Common Stock is convertible at any time at the option of the holder thereof into one share of Class A Common Stock. We will reserve and keep available out of our authorized but unissued Class A Common Stock at least the number of shares of Class A Common Stock that would become issuable upon the conversion of all shares of Class B Common Stock at any time outstanding.

Anti-Takeover Provisions

Provisions of the General Corporation Law of the State of Delaware (the “DGCL”) and of our amended and restated certificate of incorporation and bylaws may delay, defer, make more difficult or prevent a change of control of our company.

 

16


Table of Contents

Delaware Business Combination Statute

Section 203 of the DGCL, in general, prohibits a “business combination” between a corporation and an “interested stockholder” within three years of the time the stockholder became an interested stockholder, unless:

 

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

 

    upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, exclusive of shares owned by directors who are also officers and by certain employee stock plans; or

 

    at or subsequent to such time, the business combination is approved by the board of directors and authorized at a stockholders’ meeting by at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. Generally, an “interested stockholder” is a person who owns, individually or with or through other persons, 15% or more of the corporation’s outstanding voting stock.

The restrictions of Section 203 of the DGCL do not apply to corporations that have elected, in the manner provided therein, to “opt out” of Section 203 of the DGCL or, with certain exceptions, that do not have a class of voting stock that is listed on a national securities exchange or held of record by more than 2,000 stockholders. We have not elected to “opt out” of Section 203 of the DGCL and, accordingly, we are subject to Section 203 of the DGCL. Our Board of Directors could rely on this provision of the DGCL to prevent or delay an acquisition of us.

Certificate of Incorporation and Bylaws

Issuance of Common Stock. The authorized but unissued shares of our common stock are available for future issuance without stockholder approval, unless required by our amended and restated certificate of incorporation or bylaws, by the rules of the NYSE (on which our Class A Common Stock is listed), or by applicable law. These additional shares may be used 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 and unreserved common stock could also render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Advance Notice Procedures. Our bylaws provide that proposals and director nominations made by a stockholder to be voted upon at any annual meeting or special meeting of stockholders may be taken only if such proposal or director nomination is “properly brought” before such meeting. In order for any matter to be considered “properly brought” before an annual meeting or a special meeting, a stockholder must comply with certain requirements regarding advance notice to the company. The advance notice provisions could have the effect of delaying, until the next stockholders meeting, stockholder actions which are favored by the holders of a majority of our outstanding voting stock.

Special Meetings of Stockholders. Stockholders do not have the right to call special meetings of stockholders. Only the Chairman of our Board of Directors or our Chief Executive Officer, upon the request of a majority of the Board of Directors, may call a special meeting of stockholders. The only business that may be conducted at a special meeting of stockholders is the business properly brought before the meeting pursuant to our notice of meeting. This provision will make it more difficult for stockholders to take action opposed by the Board of Directors.

Transfer Agent

The transfer agent and registrar for our common stock is Computershare.

Significant Provisions of the Warrant Agreements

We will issue the warrants under one or more warrant agreements to be entered into between us and a bank or trust company, as warrant agent, in one or more series, which will be described in the prospectus supplement for the warrants. The following summaries of significant provisions of the warrant agreements and the warrants are not intended to be comprehensive, and holders of warrants should review the detailed description of the relevant warrant agreement included in any prospectus supplement.

Modifications Without Consent of Warrantholders

We and the warrant agent may amend the terms of the warrants and the warrant certificates without the consent of the holders to:

 

    cure any ambiguity;

 

    cure, correct or supplement any defective or inconsistent provision; or

 

    amend the terms in any other manner which we may deem necessary or desirable and which will not adversely affect the interests of the affected holders in any material respect.

Enforceability of Rights of Warrantholders

The warrant agents will act solely as our agents in connection with the warrant certificates and will not assume any obligation or relationship of agency or trust for or with any holders of warrant certificates or beneficial owners of warrants. Any holder of warrant certificates and any beneficial owner of warrants may, without the consent of any other person, enforce by appropriate legal action, on its own behalf, its right to exercise the warrants evidenced by the warrant certificates in the manner provided for in that series of warrants or pursuant to the applicable warrant agreement. No holder of any warrant certificate or beneficial owner of any warrants will be entitled to any of the rights of a holder of the debt securities or any other warrant property, if any, purchasable upon exercise of the warrants, including, without limitation, the right to receive the payments on those debt securities or other warrant property or to enforce any of the covenants or rights in the relevant indenture or any other similar agreement.

Registration and Transfer of Warrants

Subject to the terms of the applicable warrant agreement, warrants in registered, definitive form may be presented for exchange and for registration of transfer at the corporate trust office of the warrant agent for that series of warrants, or at any other office indicated in the prospectus supplement relating to that series of warrants, without service charge. However, the holder will be required to pay any taxes and other governmental charges as described in the warrant agreement. The transfer or exchange will be effected only if the warrant agent for the series of warrants is satisfied with the documents of title and identity of the person making the request.

New York Law to Govern

The warrants and each warrant agreement will be governed by, and construed in accordance with, the laws of the State of New York.

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts, including contracts obligating holders to purchase from us and us to sell to the holders, a specified principal amount of debt securities or a specified number of shares of Class A Common Stock or any of the other securities that we may sell under this prospectus (or a range of principal amount or number of shares pursuant to a predetermined formula) at a future date or dates. The consideration payable upon settlement of the purchase contracts may be fixed at the time the purchase contracts are issued or may be determined by a specific reference to a formula set forth in the purchase contracts. The purchase contracts may be issued separately or as part of units consisting of a purchase contract and other securities or obligations issued by us or third parties, including United States treasury securities, securing the holders’ obligations to purchase the relevant securities under the purchase contracts. The purchase contracts may require us to make periodic payments to the holders of the purchase contracts or units or vice versa, and the payments may be unsecured or prefunded on some basis. The purchase contracts may require holders to secure their obligations under the purchase contracts in a specified manner and in some circumstances we may deliver newly issued prepaid purchase contracts, often referred to as “prepaid securities,” upon release to a holder of any collateral securing such holder’s obligations under the original purchase contract.

The applicable prospectus supplement will describe the terms of any purchase contracts or purchase units and, if applicable, such other securities or obligations. The description in the prospectus supplement will not necessarily be complete and will be qualified in its entirety by reference to the purchase contracts, and, if applicable, collateral arrangements, relating to the purchase contracts.

DESCRIPTION OF UNITS

We may issue units consisting of one or more purchase contracts, warrants, debt securities, shares of Class A Common Stock or any combination of such securities. The applicable prospectus supplement will describe:

 

    the terms of the units and of the purchase contracts, warrants, debt securities and/or Class A Common Stock comprising the units, including whether and under what circumstances the securities comprising the units may be traded separately;

 

    a description of the terms of any unit agreement governing the units; and

 

    a description of the provisions for the payment, settlement, transfer or exchange of the units.

PLAN OF DISTRIBUTION

From time to time, we may sell the securities offered by this prospectus:

 

    through underwriters or dealers;

 

    through agents;

 

    directly to purchasers; or

 

    through a combination of any of these methods of sale.

This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement. Any underwriter, dealer or agent may be deemed to be an “underwriter” within the meaning of the Securities Act.
