Recent Developments

        On May 15, 2011, we entered into an Agreement and Plan of Merger (the "Merger Agreement") with Integral Systems, Inc., a Maryland corporation ("Integral Systems"), IRIS Merger Sub Inc., a Maryland corporation and our wholly owned subsidiary ("Merger Sub"), and IRIS Acquisition

2

Table of Contents

Sub LLC, a Maryland limited liability company and our wholly owned subsidiary ("Merger LLC"). Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Integral Systems, and Integral Systems will continue as the surviving corporation and as a wholly owned subsidiary of the Company (the "Merger"). The boards of directors of the Company and Integral Systems have unanimously approved the Merger Agreement and the transactions contemplated thereby.

        At the effective time of the Merger (the "Effective Time"), holders of Integral Systems common stock will be entitled to receive (i) $5.00 in cash, without interest, and (ii) 0.588 shares of the Company's common stock for each share of Integral Systems common stock they own (the "Merger Consideration").

        In addition, at the Effective Time, each Integral Systems stock option that has an exercise price less than $13.00 per share shall, if the holder thereof elects in writing, be cancelled in exchange for an amount in cash, without interest, equal to the product of the total number of shares of Integral Systems common stock subject to such in-the-money option, multiplied by the aggregate value of the excess, if any, of $13.00 over the exercise price per share subject to such option, less the amount of any tax withholding. Each Integral Systems stock option that has an exercise price equal to or greater than $13.00 per share and each Integral Systems in-the-money option the holder of which does not make the election described in the preceding sentence shall be converted into an option to purchase Kratos common stock, with (i) the number of shares subject to such option adjusted to equal the number of shares of Integral Systems common stock subject to such out-of-the-money option multiplied by 0.9559, rounded up to the nearest whole share, and (ii) the per share exercise price under each such option adjusted by dividing the per share exercise price under such option by 0.9559, rounded up to the nearest whole cent. Each share of restricted stock granted under an Integral Systems equity plan or otherwise, whether vested or unvested, that is outstanding immediately prior to the completion of the Merger shall be cancelled and the holder thereof shall be entitled to receive an amount in cash, without interest, equal to the product of the total number of restricted shares of Integral Systems common stock held by such holder, multiplied by $13.00, less the amount of any tax withholding. No fractional shares of Company common stock will be issued in the Merger. The Merger is intended to qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

        Completion of the Merger is subject to various customary conditions, including, among other things: (i) the approval of the stockholders of each of the Company and Integral Systems; (ii) subject to certain materiality exceptions, the accuracy of the representations and warranties made by each of the Company and Integral Systems and the compliance by each of the Company and Integral Systems with their respective obligations under the Merger Agreement; (iii) obtaining clearance under the Hart-Scott-Rodino Antitrust Improvements Act, as amended; and (iv) the declaration of the effectiveness by the SEC of the Registration Statement on Form S-4 filed by the Company on June 7, 2011.

        The Merger Agreement contains customary representations, warranties and covenants, including covenants obligating the Company and Integral Systems to continue to conduct their respective businesses in the ordinary course and to cooperate on seeking regulatory approvals and providing access to each other's information. The Merger Agreement also contains a representation by the Company regarding the availability of funds to complete the transactions contemplated by the Merger Agreement, including certain financing commitments, and a customary "no solicitation" provision pursuant to which, prior to the completion of the Merger, neither the Company nor Integral Systems is permitted to solicit or engage in discussions with any third party regarding another acquisition proposal unless it has received an unsolicited proposal or offer that the recipient's board of directors determines is or could reasonably be expected to result in a "Superior Proposal".

        The Merger Agreement contains certain termination rights in favor of each of the Company and Integral Systems, including each party's right to terminate the Merger Agreement under certain circumstances in connection with the acceptance of a "Superior Proposal". In addition, the Merger Agreement provides that in connection with certain terminations of the Merger Agreement, depending on the circumstances surrounding the termination, one party may be required to pay the other a termination fee of $9.3 million.

Background

Department of Defense Drives Strategic Priorities for the Company

        The delivery and execution of our mission-critical engineering and support services are driven by the priorities of the U.S. Federal Government and primarily the DoD. The strategic priorities of the DoD are based in large part on the Quadrennial Defense Review, a legislatively mandated review of DoD strategy and priorities. These priorities are currently focused on mission-critical capabilities of the U.S. armed forces and providing the support infrastructure necessary to sustain these forces in a time of heightened warfare readiness and deployment.

        The DoD's budget for the 2012 fiscal year is $671.0 billion, a decrease of 5% from fiscal year 2011. The top 28 programs account for approximately $64.0 billion in funding and require aggregate funding that is nearly 14% higher than what was set aside for them in the fiscal year 2010 budget, which closed on September 30, 2010. The increase in the top 28 programs represents a significant opportunity to key federal government contractors in support of the DoD's war fighter, information technology, and other operational priorities. We believe there will be significant market opportunities for providers of system sustainment, information technology ("IT") and engineering services and solutions to federal government agencies over the next several years, particularly those in the defense and homeland security communities.

        The entire federal government is currently operating under the authority of a continuing resolution (the "Continuing Resolution") for the fiscal year ending September 30, 2011. The Continuing Resolution funds programs and services, including DoD budgets, at approximately the same levels as fiscal year 2010. The Continuing Resolution runs through September 30, 2011, after which Congress will either pass a new appropriations bill, extend the Continuing Resolution, or shut down the government for all nonessential federal government services.

Focus on Federal Government Transformation

        The federal government, and the DoD in particular, is in the midst of a significant transformation that is driven by the federal government's need to address the changing nature of global threats. A significant aspect of this transformation is the use of C5ISR and information technology to increase the federal government's effectiveness and efficiency. The result is increased federal government spending on information technology to upgrade networks and transform the federal government from separate, isolated organizations into larger, enterprise level, network-centric organizations capable of sharing information broadly and quickly. While the transformation initiative is driven by the need to prepare for new world threats, adopting these IT transformation initiatives will also improve efficiency and reduce infrastructure costs across all federal government agencies.

        An additional aspect of the military transformation includes significantly enhancing military readiness in areas such as missile defense, weapons system sustainment and extension, and the overall strengthening of intelligence and security. For example, the objective of the DoD as it relates to missile defense is to continue to develop, test, and field missile defense systems to protect America, its allies and deployed forces.

Table of Contents

        While the real rate of growth in the top line defense budget may be slowing for the first time since September 11, 2001, the U.S. Government's budgetary process continues to give us good visibility with respect to future spending and the threat areas that the government is addressing. We believe that our business is aligned with mission-critical national security priorities, particularly in the area of missile defense, C5ISR, cyber security and information assurance, and that our current contracts and strong backlog provide us with good insight regarding our future cash flows.

Competitive Strengths

        We believe we have robust capabilities and past performance qualifications in our respective business areas, including a work force that is experienced with the various programs we service and the customers we serve. Additionally, a majority of our employees have national security clearances specifically related to the customers they work for and the contracts which they work on. We believe the following key strengths distinguish us competitively:

Significant and Highly Specialized Experience

        Through existing customer engagements and the government focused acquisitions we have completed over the past several years, we have amassed significant and highly specialized experience in areas directly related to C5ISR weapon system lifecycle extension and sustainment; missile, rocket and weapons system testing and evaluation; military range operations and technical services; and other highly differentiated services and solutions. This collective experience, or past performance qualifications, is a requirement for the majority of our contract vehicles and customer engagements. Further enhancing our specialized expertise, a majority of our approximately 2,900 employees have national security clearances, including top secret and higher. We believe these characteristics represent a significant competitive strength and position us to win renewal or follow-on business.

Specialized National Security Focus Aligned with Mission-Critical National Security Priorities

        Continued concerns related to the threat posed by certain foreign nations and terrorists have caused the U.S. Government to identify national security as an area of functional and spending priority. Budget pressures, particularly related to DoD spending, have placed a premium on developing and fielding relatively low-cost, high-technology solutions to assist in national security missions. Our primary capabilities and areas of focus, listed below, are strongly aligned with the objectives of the U.S. Government:

•

Intelligence, surveillance and reconnaissance



•

Command and control



•

Unmanned systems



•

Ballistic missile defense



•

Cyber security and information assurance

Strategic Geographic Locations and Base Realignment and Closure

        The U.S. Base Realignment and Closure Act of 2005 ("BRAC") is the congressionally authorized process the DoD has implemented to reorganize its base structure to fewer, larger bases in order to support U.S. armed forces more efficiently and effectively, increase operational readiness and facilitate new ways of doing business. As a result of the DoD's BRAC transformation, we have concentrated part of our business strategy on building a significant presence in key BRAC receiving locations where the U.S. Federal Government is relocating its personnel and related technical and professional services. We

5

---

Table of Contents

believe our focus on increasing our strategic presence in key BRAC receiving locations will provide us with a significant competitive advantage

Diverse Base of Key Contracts with Low Concentration

        As a result of our business development focus on securing key contracts, we are a preferred contractor on numerous multiyear, government-wide acquisition contracts ("GWACs") and multiple award contracts. Our preferred contractor status provides us with the opportunity to bid on hundreds of millions of dollars of business each year against a discrete number of other prequalified companies. We have a highly diverse base of contracts with no contract representing more than 5% of 2010 revenue. Our fixed price contracts, almost all of which are production contracts, represent approximately 57% of our 2010 revenue. Our cost-plus-fee contracts and time and materials contracts represent approximately 22% and 21%, respectively, of our 2010 revenue. We believe our diverse base of key contracts and low reliance on any one contract provides us with a stable, balanced revenue stream.

In-Depth Understanding of Client Missions

        We have a reputation for providing mission-critical services and solutions to our clients. Our relationships with our U.S. Army, U.S. Navy and U.S. Air Force customers generally exceed 10 years, enabling us to develop an in-depth understanding of their missions and technical needs. In addition, we have employees located at customer sites, providing us with valuable strategic insights into our clients' ongoing and future program requirements. Our in-depth understanding of our clients' missions, in conjunction with the strategic location of our employees, enables us to offer technical solutions tailored to our clients' specific requirements and evolving mission objectives. In addition, once we are on-site with a customer, we have historically been successful in winning recompete business in the vast majority of cases.

Significant Cash Flow Visibility Driven by Stable Backlog

        As of March 27, 2011, our total backlog, on a pro forma basis with Herley and Integral Systems, was approximately $1.2 billion, of which approximately $676.0 million was funded backlog. The majority of our sales are from orders issued under long-term contracts, typically three to five years in duration. Our contract backlog provides visibility into stable future revenue and cash flow over a diverse set of contracts.

Highly Skilled Employees and an Experienced Management Team

        We deliver our services through a skilled workforce of approximately 2,900 employees. Our senior managers have significant experience with U.S. Federal Government agencies, the U.S. military and federal government contractors. Members of our management team have experience growing businesses both organically and through acquisitions. We believe that the cumulative experience and differentiated expertise of our personnel in our core focus areas, coupled with our sizable employee base, the majority of which hold national security clearances, allows us to qualify for and bid on larger projects in a prime contracting role.

Our Strategy

        Our strategy is to grow our business as a leading provider of highly differentiated products, solutions and services in our core areas of focus as noted above by delivering comprehensive, high-end engineering services, technical solutions, product manufacturing, and information technology solutions to federal government agencies, while improving our margin rates and overall profitability.

Capitalize on Current Contract Base

        We are pursuing new program and contract opportunities and awards, as we build the business, with our expanding customer base, contract portfolio, and product, solution and service offerings. We are aggressively pursuing task orders under existing contract vehicles to maximize our revenue and strengthen our client relationships, though there is no assurance that the federal government will make awards up to the ceiling amounts or that we will be awarded any task orders under these vehicles. We have developed several internal tools that facilitate our ability to track, prioritize and win task orders under these vehicles. Combining these tools with our technical expertise, our strong past performance record and our knowledge of our clients' needs should position us to win additional task orders.

Expand Product, Solution and Service Offerings Provided to Existing Clients

        We are focused on expanding the products, solutions and services we provide to our current clients by leveraging our strong relationships, technical capabilities and past performance record, and by offering a wider range of comprehensive solutions as we continue to acquire companies with new areas of specialization. In regard to new areas of specialization, two of our recent acquisitions have expanded our service offerings to include manufacturing of tactical combat vehicle shelters for C5ISR systems, unmanned systems, weapon systems and warfighters. We believe our understanding of client missions, processes and needs, in conjunction with our full lifecycle IT offerings, including cybersecurity, cyberwarfare and situational awareness, positions us to capture new work from existing clients as the federal government continues to increase the volume of IT services contracted to professional services providers. Moreover, we believe our strong past performance record positions us to expand the level of services we provide to our clients.

Expand Client and Contract Base

        We are also focused on expanding our client base into areas with significant growth opportunities by leveraging our capabilities, industry reputation, long-term client relationships and diverse contract base. We anticipate that this expansion will enable us to both pursue additional higher value work and to further diversify our revenue base across the federal government. Our long-term relationships with federal government agencies, together with our GWAC vehicles, give us opportunities to win contracts with new clients within these agencies.

Improve Operating Margins

        We believe that we have opportunities to increase our operating margins and improve profitability by capitalizing on our corporate infrastructure investments and internally developed tools, improving efficiencies and reducing costs, and concentrating our efforts on increasing the percentage of revenues generated from high value added contracts.

Capitalize on Corporate Infrastructure Investments

        In recent periods, we have made significant investments in our senior management and corporate infrastructure in anticipation of future revenue growth. These investments included hiring senior executives with significant experience in the national security industry, strengthening our internal controls over financial reporting and accounting staff in support of public company reporting requirements, expanding our Sensitive Compartmented Information Facilities and other corporate facilities, and expanding our backlog and bid and proposal pipeline. We will be allocating additional resources in our pursuit of new and larger contract opportunities, leveraging our increased scale and robust past performance qualifications. We believe our management experience and corporate infrastructure are more typical of a company with a much larger revenue base than ours. We therefore

7

---

Table of Contents

anticipate that, to the extent our revenue grows, we will be able to leverage this infrastructure base and increase our operating margins.

Concentrate on High Value Added Contracts

        We expect to improve our operating margins as we strive to increase the percentage of revenue we derive from our work as a contractor and from engagements where contracts are awarded on a best value, rather than on a low cost, basis. The federal government's move toward performance-based contract awards to realize greater return on its investment has resulted in a shift to greater utilization of best value awards. We believe this shift will enable us to expand our operating margins as we are awarded more contracts of this nature.

Pursue Strategic Acquisitions

        We intend to supplement our organic growth by identifying, acquiring and integrating businesses that meet our primary objective of providing us with enhanced capabilities to pursue a broader cross section of the DoD, Department of Homeland Security and other government markets, complement and broaden our existing client base and expand our primary service offerings. Our senior management team has significant acquisition experience.

Summary of the Terms of the Exchange Offer

        On March 25, 2011, Acquisition Co. Lanza Parent, a Delaware corporation and an indirect wholly owned subsidiary of the Company (the "Stage I Issuer"), issued $285.0 million aggregate principal amount of its 10% Senior Secured Notes due 2017 (the "Stage I Notes") pursuant to an indenture, dated as of March 25, 2011, among the Stage I Issuer, the guarantor party thereto and Wilmington Trust FSB ("Wilmington Trust"), as trustee and collateral agent (the "Stage I Indenture"). On April 4, 2011, the Stage I Issuer merged with and into the Company, and the Company assumed all the assets and liabilities of the Stage I Issuer including, pursuant to a supplemental indenture to the Stage I Indenture, all the obligations of the Stage I Issuer under the Stage I Indenture, the Stage I Notes and the Collateral Agreements (as defined in the Stage I Indenture) and (ii) the Company became the issuer of the Stage I Notes under the Stage I Indenture and pledgor under such Collateral Agreements. In addition, on April 15, 2011, the Company redeemed all of the outstanding Stage I Notes by issuing to each holder of Stage I Notes (each, a "Holder" and collectively, the "Holders") in exchange therefor the Original Notes issued by the Company pursuant to the Indenture in a like principal amount. On March 25, 2011, in connection with the issuance of the Stage I Notes, we entered into a registration rights agreement in which we agreed that you, as a holder of unregistered Original Notes, would be entitled to exchange your unregistered Original Notes for Exchange Notes registered under the Securities Act. The exchange offer is intended to satisfy these rights. After the exchange offer is completed, you will no longer be entitled to any registration rights with respect to your Original Notes. The Exchange Notes will be our obligation and will be entitled to the benefits of the Indenture relating to the Exchange Notes. The form and terms of the Exchange Notes are identical in all material respects to the form and terms of the Original Notes, except that the Exchange Notes will:

•

have been registered under the Securities Act and, therefore, will contain no restrictive legends;



•

not have registration rights;



•

not have rights to additional interest; and



•

bear different CUSIP and ISIN numbers from the Original Notes.

You should read the discussion under the heading "The Exchange Offer" beginning on page 27 and "Description of the Exchange Notes" beginning on page 37 for further information about the exchange offer and the Exchange Notes.

RISK FACTORS

        An investment in the Exchange Notes involves significant risks. You should consider carefully the following risk factors and all of the information contained in this prospectus before deciding whether to participate in the exchange offer. The risks and uncertainties described below are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. If any of those risks actually occurs, our business, financial condition and results of operations would suffer. The risks discussed below also include forward-looking statements. See "Forward-Looking Statements" in this prospectus.

Risks Related to the Exchange Notes and the Exchange Offer

We significantly increased our leverage in connection with the financing of recent acquisitions and the Transactions and currently have substantial indebtedness, which could have a negative impact on our financing options and liquidity position and have adverse effects on our business.

        In connection with the Transactions, we incurred an additional $285.0 million of indebtedness and, as of March 27, 2011, have approximately $521.1 million of total indebtedness. As a result of this increased indebtedness, our interest payment obligations have increased significantly. The degree to which we are leveraged could have adverse effects on our business, including the following:

•

it may make it difficult for us to satisfy our obligations under the Kratos Notes and our other indebtedness and contractual and commercial commitments;



•

it may limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate;



•

it may require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures and other general corporate purposes;



•

it may restrict us from making strategic acquisitions or exploiting business opportunities;



•

it may place us at a competitive disadvantage compared to our competitors that have less debt;



•

it may limit our ability to borrow additional funds;



•

it may prevent us from raising the funds necessary to repurchase the Kratos Notes or other outstanding notes tendered to us if there is a change of control, which would constitute a default under the Indenture and under the Revolver; and



•

it may decrease our ability to compete effectively or operate successfully under adverse economic and industry conditions.

        Our ability to meet our debt service obligations will depend upon our future performance, which may be subject to financial, business and other factors affecting our operations, many of which are beyond our control.

Despite our current indebtedness level, we and our subsidiaries may still be able to incur substantially more debt, which could exacerbate the risks associated with our substantial leverage.

        We may be able to incur substantial additional indebtedness in the future. Although the Indenture and the credit agreement governing the Revolver will limit our ability and the ability of our subsidiaries to incur additional indebtedness, these restrictions are subject to a number of qualifications and exceptions and, under certain circumstances, debt incurred in compliance with these restrictions could be substantial. For example, indebtedness in excess of $25.0 million may be incurred under the Revolver in reliance on the $15.0 million general debt basket as well as the fixed charge debt

14

Table of Contents

incurrence test, which additional indebtedness may be secured subject to certain conditions. See clause (22) of the definition of the term "Permitted Liens" under "Description of the Exchange Notes—Certain Definitions." In addition, the Indenture and the credit agreement governing the Revolver will not prevent us from incurring obligations that do not constitute indebtedness. See the sections entitled "Description of the Exchange Notes—Certain Covenants—Limitation on Incurrence of Additional Indebtedness and Issuance of Preferred Stock" and "Description of Certain Indebtedness." To the extent that we incur additional indebtedness or such other obligations, the risks associated with our substantial leverage described above, including our possible inability to service our debt, would increase.

Our debt service obligations may adversely affect our cash flow.

        A higher level of indebtedness increases the risk that we may default on our debt obligations. We may not be able to generate sufficient cash flow to pay the interest on our debt, and future working capital, borrowings or equity financing may not be available to pay or refinance such debt. If we are unable to generate sufficient cash flow to pay the interest on our debt, we may have to delay or curtail our operations.

        Our ability to generate cash flows from operations and to make scheduled payments on our indebtedness will depend on our future financial performance. Our future financial performance will be affected by a range of economic, competitive and business factors that we cannot control. A significant reduction in operating cash flows resulting from changes in economic conditions, increased competition or other events beyond our control could increase the need for additional or alternative sources of liquidity and could have a material adverse effect on our business, financial condition, results of operations, prospects and our ability to service our debt and other obligations. If we are unable to service our indebtedness, we will be forced to adopt an alternative strategy that may include actions such as reducing capital expenditures, selling assets, restructuring or refinancing our indebtedness or seeking additional equity capital. These alternative strategies may not be effected on satisfactory terms, if at all, and they may not yield sufficient funds to make required payments on the Kratos Notes and our other indebtedness.

        If for any reason we are unable to meet our debt service and repayment obligations, we would be in default under the terms of the agreements governing our debt, which would allow our creditors at that time to declare certain outstanding indebtedness to be due and payable, which would in turn trigger cross-acceleration or cross-default rights between the relevant agreements. In addition, our lenders could compel us to apply all of our available cash to repay our borrowings or they could prevent us from making payments on the Kratos Notes. If the amounts outstanding under the Kratos Notes, the Revolver, and any other indebtedness, were to be accelerated, our assets may not be sufficient to repay in full the money owed to the lenders or to our other debt holders, including you as noteholders.

A portion of our business is conducted through foreign subsidiaries and the failure to generate sufficient cash flow from these subsidiaries, or otherwise repatriate or receive cash from these subsidiaries, could result in our inability to repay our indebtedness, including the Exchange Notes.

        As of March 27, 2011, approximately 4% of our consolidated assets, based on book value, were held by foreign subsidiaries. Our ability to meet our debt service obligations (including those relating to the Exchange Notes) with cash from foreign subsidiaries will depend upon the results of operations of these subsidiaries and may be subject to legal, contractual or other restrictions and other business considerations. In addition, dividend and interest payments to us from the foreign subsidiaries may be subject to foreign withholding taxes, which would reduce the amount of funds we receive from such foreign subsidiaries. Dividends and other distributions from our foreign subsidiaries may also be subject

15

---

Table of Contents

to fluctuations in currency exchange rates and legal and other restrictions on repatriation, which could further reduce the amount of funds we receive from such foreign subsidiaries.

        In general, when an entity in a foreign jurisdiction repatriates cash to the U.S., the amount of such cash is treated as a dividend taxable at current U.S. tax rates. Accordingly, upon the distribution of cash to us from our foreign subsidiaries, we will be subject to U.S. income taxes. Although foreign tax credits may be available to reduce the amount of the additional tax liability, these credits may be limited and only offset the tax paid in the foreign jurisdiction, not the excess of the U.S. tax rate over the foreign tax rate. Therefore, to the extent that we must use cash generated in foreign jurisdictions to make principal or interest payments on the Kratos Notes, there may be a cost associated with repatriating the cash to the U.S.

The lien-ranking provisions set forth in the intercreditor agreement will substantially limit the rights of the holders of the Kratos Notes with respect to liens on the assets (other than Notes Priority Collateral) securing the Kratos Notes and the Kratos Guarantees.

        The liens on our assets (other than Notes Priority Collateral, defined under "Description of the Exchange Notes—Collateral") securing the Kratos Notes and the Kratos Guarantees will be contractually subordinated to the liens thereon that secure the Revolver and will be pari passu with the liens that secure the Kratos Notes. The holders of obligations under the Revolver will be entitled to receive proceeds from any realization of such collateral to repay their obligations in full before the holders of the Kratos Notes and other obligations secured by liens subordinated to the Revolver will be entitled to any recovery from such collateral. In the event of a foreclosure, the proceeds from the sale of all of such collateral may not be sufficient to satisfy the amounts outstanding under the Kratos Notes after payment in full of all obligations secured by the Revolver.

        The rights of the holders of the Kratos Notes with respect to the liens on our assets (other than Notes Priority Collateral) securing the Kratos Notes and the Kratos Guarantees will therefore be substantially limited pursuant to the terms of the lien-ranking provisions set forth in the intercreditor agreement. Under those lien-ranking provisions, at any time that the Revolver is outstanding, any actions that may be taken in respect of such assets, including the ability to cause the commencement of enforcement proceedings against such assets and to control the conduct of such proceedings, and the approval of releases of such assets from the lien of the collateral documents, will be at the direction of the lenders under the Revolver. The trustee, on behalf of the holders of the Kratos Notes, will not, for significant periods of time, have the ability to control or direct such actions, even if the rights of the holders of the Kratos Notes are adversely affected. See "Description of the Exchange Notes—Intercreditor Agreement."

The imposition of certain permitted liens will cause the assets on which such liens are imposed to be excluded from the collateral securing the Kratos Notes and the Kratos Guarantees. There are also certain other categories of property that are also excluded from the collateral.

        The Indenture permits liens in favor of third parties to secure certain indebtedness, such as indebtedness incurred under the Revolver (which could exceed $35.0 million in the aggregate), purchase money indebtedness and capital lease obligations, and assets subject to such liens will in certain circumstances be excluded from the collateral securing the Kratos Notes and the Kratos Guarantees. Our ability to incur purchase money indebtedness and capital lease obligations on a secured basis is subject to limitations as described in "Description of the Exchange Notes—Certain Covenants—Limitation on Incurrence of Additional Indebtedness and Issuance of Preferred Stock" and "—Limitation on Liens." Certain of these third party liens rank senior to the liens securing the Kratos Notes. In addition, certain categories of assets are excluded from the collateral securing the Kratos Notes and the Kratos Guarantees and the liens on certain categories of assets are not required to be perfected. Excluded assets include certain contracts, certain equipment, and the assets of any

16

Table of Contents

non-guarantor subsidiary and certain capital stock of certain subsidiaries. See "Description of the Exchange Notes—Collateral." If an event of default occurs and the Kratos Notes are accelerated, the Kratos Notes and the Kratos Guarantees will rank equally with the holders of other unsubordinated and unsecured indebtedness of the relevant entity with respect to such excluded property and will be effectively subordinated to holders of obligations secured by a lien perfected on such excluded property.

The value of the collateral securing the Kratos Notes may not be sufficient to satisfy all the obligations evidenced by or relating to such Kratos Notes secured by such collateral. As a result, holders of such Kratos Notes may not receive full payment on such Kratos Notes following an event of default.

        No appraisal has been made of the collateral securing the Kratos Notes. The value of the collateral in the event of liquidation will depend upon market and economic conditions, the availability of buyers and similar factors. The collateral does not include contracts, agreements, licenses and other rights that by their express terms prohibit the assignment thereof or the grant of a security interest therein. Some of these may be material to us and such exclusion could have a material adverse effect on the value of the collateral. By its nature, some or all of the collateral may not have a readily ascertainable market value or may not be saleable or, if saleable, there may be substantial delays in its liquidation. To the extent that liens, security interests and other rights granted to other parties (including with respect to collateral that secures such Kratos Notes, the lenders under the Revolver) encumber assets owned by us, those parties have or may exercise rights and remedies with respect to the property subject to their liens that could adversely affect the value of that collateral and the ability of the trustee under the Indenture governing the Kratos Notes or the holders thereof to realize or foreclose on that collateral. Consequently, we cannot assure investors in the Kratos Notes that liquidating the collateral securing the Kratos Notes would produce proceeds in an amount sufficient to pay in full any amounts due under such Kratos Notes after also satisfying the obligations to pay any creditors with prior claims on the collateral, including, with respect to collateral that secures such Kratos Notes, the lenders under the Revolver. If the proceeds of any sale of collateral are not sufficient to repay all amounts due on the Kratos Notes, the holders of the Kratos Notes (to the extent not repaid from the proceeds of the sale of the collateral securing the Kratos Notes) would have only an unsecured, unsubordinated claim against our and the guarantors' remaining assets. In addition, under the intercreditor agreement between the collateral agent for the Kratos Notes and the agent under the Revolver, the right of the lenders to exercise certain remedies with respect to the collateral could delay liquidation of the collateral. Bankruptcy laws and other laws relating to foreclosure and sale could also substantially delay or prevent the ability of the collateral agent or any holder of the Kratos Notes to obtain the benefit of any collateral securing the Kratos Notes. Such delays could have a material adverse effect on the value of the collateral.

        Consequently, liquidating the collateral securing the Kratos Notes and the Kratos Guarantees may not result in proceeds in an amount sufficient to pay any amounts due under the Kratos Notes and holders of pari passu claims after also satisfying the obligations to pay any creditors with prior liens (including the lenders under the Revolver). If the proceeds of any sale of collateral are not sufficient to repay all amounts due on the Kratos Notes, the holders of such Kratos Notes (to the extent not repaid from the proceeds of the sale of the collateral securing such Kratos Notes) would have only an unsecured, unsubordinated claim against our remaining assets and the remaining assets of the guarantors of such Kratos Notes.

Table of Contents

The Indenture and the credit agreement governing our Revolver impose significant operating and financial restrictions on us and our subsidiaries that may prevent us and our subsidiaries from pursuing certain business opportunities and restrict our ability to operate our business.

        The Indenture and the credit agreement governing our Revolver contain covenants that restrict our and our subsidiaries' ability to:

•

incur or guarantee additional indebtedness or issue certain preferred stock;



•

pay dividends or make other distributions on, or redeem or purchase, any equity interests or make other restricted payments;



•

make certain acquisitions or investments;



•

create or incur liens;



•

transfer or sell assets;



•

incur restrictions on the payments of dividends or other distributions from our restricted subsidiaries;



•

enter into transactions with affiliates; and



•

consummate a merger or consolidation or sell, assign, transfer, lease or otherwise dispose of all or substantially all of our assets.

        Our Revolver also requires us to comply with specified financial ratios, including a borrowing base availability and minimum fixed charge coverage ratio. Our ability to comply with these covenants will likely be affected by many factors, including events beyond our control, and we may not be able to satisfy those requirements. Our failure to comply with our debt-related obligations could result in an event of default under our other indebtedness and the acceleration of our other indebtedness, in whole or in part, could result in an event of default under the Indenture.

        The restrictions contained in the Indenture and in the credit agreement governing the Revolver will also limit our ability and the ability of our subsidiaries to plan for or react to market conditions, meet capital needs or otherwise restrict our respective activities or business plans and adversely affect the ability to finance our respective operations, enter into acquisitions or to engage in other business activities that would be in our respective interests.

The collateral will in most cases be under our control and the sale of particular assets by us could reduce the pool of assets securing the Kratos Notes and the Kratos Guarantees secured thereby.

        The collateral documents allow us to remain in possession of, retain exclusive control over, freely operate, and collect, invest and dispose of any income from, the collateral securing the Kratos Notes and the related guarantees secured thereby. There are circumstances other than repayment or discharge of the Kratos Notes under which the collateral securing the Kratos Notes and the Kratos Guarantees will be released automatically, without your consent or the consent of the trustee, including:

•

a sale, transfer or other disposal of such collateral in a transaction not prohibited under the Indenture governing the Kratos Notes;



•

with respect to collateral held by a guarantor, upon the release of such guarantor from its guarantee of the Kratos Notes;

18

---

Table of Contents

•

with respect to collateral that is capital stock, upon the dissolution of the issuer of such capital stock in accordance with the Indenture governing the Kratos Notes; and



•

with respect to our assets (other than Notes Priority Collateral) that secure the Revolver, upon any release in connection with a foreclosure or exercise of remedies with respect to such collateral in accordance with the terms of the Revolver.

        Pursuant to the terms of the intercreditor agreement, the holders of the Kratos Notes may not be able to control actions with respect to the collateral, whether or not the holders of the Kratos Notes agree or disagree with those actions.

        In addition, the Indenture also permits us to designate any existing or future restricted subsidiary that is a guarantor of the Kratos Notes or any future subsidiary as an unrestricted subsidiary. If we designate such a future subsidiary guarantor as an unrestricted subsidiary for purposes of the Indenture, all of the liens on any collateral owned by such subsidiary or any of its subsidiaries and any guarantees of the Kratos Notes by such subsidiary or any of its subsidiaries will be released under the Indenture but not necessarily under the Revolver. Designation of an unrestricted subsidiary will reduce the aggregate value of the collateral securing the Kratos Notes to the extent that liens on the assets of the unrestricted subsidiary and its subsidiaries are released.

The rights of holders of Kratos Notes to the collateral securing such Kratos Notes may be adversely affected by the failure to perfect security interests in the collateral and other issues generally associated with the realization of security interests in collateral.

        Your rights in the collateral securing the Kratos Notes may be adversely affected by the failure to perfect security interests in certain collateral in the future. Applicable law requires that certain property and rights acquired after the grant of a general security interest, such as real property, equipment subject to a certificate and certain proceeds, can be perfected only at the time at which such property and rights are acquired and identified. The trustee and the collateral agent for the Kratos Notes may not monitor, and we are not required to inform the trustee and the collateral agent of, the future acquisition of property and rights that constitute collateral, and necessary action may not be taken to properly perfect the security interest in such after-acquired collateral. The collateral agent for the Kratos Notes has no obligation to monitor the acquisition of additional property or rights that constitute collateral or the perfection of any security interest in favor of the Kratos Notes against third parties. A failure to monitor such acquisition and take necessary action may result in the loss of the effectiveness of the grant of the security interest therein or the priority of the security interest in favor of the holders of such Kratos Notes against third parties.

        In addition, the security interest of the collateral agent for the Kratos Notes will be subject to practical challenges generally associated with the realization of security interests in collateral. For example, the collateral agent may need to obtain the consent of third parties and make additional filings. If we are unable to obtain these consents or make these filings, the security interests may be invalid and the holders of the Kratos Notes will not be entitled to the collateral or any recovery with respect to the collateral. The collateral agent may not be able to obtain any such consent. Further, the consents of any third parties may not be given when required to facilitate a foreclosure on such collateral. Accordingly, the collateral agent may not have the ability to foreclose upon those assets, and the value of the collateral may significantly decrease. We are also not required to obtain third party consents in certain categories of collateral.

Table of Contents

The pledge of the capital stock of our subsidiaries that secure the Kratos Notes will automatically be released from the lien on them and no longer constitute collateral when the pledge of such capital stock or such other securities would require the filing of separate financial statements with the SEC for that subsidiary.

        The Kratos Notes and the Kratos Guarantees will be secured by a pledge of the stock of some of our subsidiaries. Under the SEC regulations in effect as of the date of this prospectus, if the par value, book value as carried by us or market value (whichever is greatest) of the capital stock, other securities or similar items of a subsidiary pledged as part of the collateral to secure such Kratos Notes is greater than or equal to 20% of the aggregate principal amount of the Kratos Notes then outstanding, such a subsidiary would be required to provide separate financial statements to the SEC. Therefore, the Indenture and the related collateral documents provide that any capital stock and other securities of our subsidiaries will be excluded from the collateral to the extent that the pledge of such capital stock would cause such companies to be required to file separate financial statements with the SEC pursuant to Rule 3-16 of Regulation S-X (as in effect from time to time).

        As a result, holders of the Kratos Notes could lose a portion or all of their security interest in the capital stock or other securities of those subsidiaries. It may be more difficult, costly and time-consuming for holders of the Kratos Notes to foreclose on the assets of a subsidiary that guarantees such Kratos Notes than to foreclose on its capital stock so the proceeds realized upon any such foreclosure could be significantly less than those that would have been received upon any sale of the capital stock or other securities of such subsidiary. See "Description of the Exchange Notes—Collateral."

Rights of holders of Exchange Notes in the collateral secured thereby may be adversely affected by bankruptcy proceedings.

        The right of the collateral agent for the Exchange Notes to repossess and dispose of the collateral securing the Exchange Notes upon acceleration is likely to be significantly impaired by U.S. federal bankruptcy law if bankruptcy proceedings are commenced by or against us prior to or possibly even after the collateral agent has repossessed and disposed of the collateral. Under the U.S. Bankruptcy Code, a secured creditor, such as the collateral agent for the Exchange Notes, is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from a debtor, without bankruptcy court approval. Moreover, bankruptcy law permits the debtor to continue to retain and to use collateral, and the proceeds, products, rents or profits of the collateral, even though the debtor is in default under the applicable debt instruments; provided that the secured creditor is given "adequate protection." The meaning of the term "adequate protection" may vary according to circumstances, but it is intended in general to protect the value of the secured creditor's interest in the collateral and may include cash payments or the granting of additional security, if and at such time as the court in its discretion determines, for any diminution in the value of the collateral as a result of the stay of repossession or disposition or any use of the collateral by the debtor during the pendency of the bankruptcy case. In view of the broad discretionary powers of a bankruptcy court, it is impossible to predict how long payments under the Exchange Notes could be delayed following commencement of a bankruptcy case, whether or when the collateral agent would repossess or dispose of the collateral, or whether or to what extent holders of the Exchange Notes would be compensated for any delay in payment of loss of value of the collateral through the requirements of "adequate protection." Furthermore, in the event the bankruptcy court determines that the value of the collateral is not sufficient to repay all amounts due on the Exchange Notes, the holders of the Exchange Notes would have "under-secured claims" as to the difference. Federal bankruptcy laws do not permit the payment or accrual of interest, costs and attorneys' fees for "under-secured claims" during the debtor's bankruptcy case. Additionally, the collateral agent's ability to foreclose on the collateral on your behalf may be subject to the consent of third parties, prior liens and practical problems associated with the realization of the trustee's security interest in the collateral. Moreover, the debtor or trustee in a

20

---

Table of Contents

bankruptcy case may seek to void an alleged security interest in collateral for the benefit of the bankruptcy estate. It may successfully do so if the security interest is not properly perfected or was perfected within a specified period of time (generally 90 days) prior to the initiation of such proceeding. Under such circumstances, a creditor may hold no security interest and be treated as holding a general unsecured claim in the bankruptcy case. It is impossible to predict what recovery (if any) would be available for such an unsecured claim if we became a debtor in a bankruptcy case. While U.S. bankruptcy law generally invalidates provisions restricting a debtor's ability to assume and/or assign a contract, there are exceptions to this rule which could be applicable in the event that we become subject to a U.S. bankruptcy proceeding.

Under certain circumstances, a court could cancel the Exchange Notes or the Exchange Guarantees and the security interests that secure the Exchange Notes and such Exchange Guarantees under fraudulent conveyance laws.

        The issuance of the Exchange Notes and the related Exchange Guarantees may be subject to review under U.S. federal or state fraudulent transfer laws. If we become a debtor in a case under the U.S. Bankruptcy Code or encounter other financial difficulty, a court could avoid (that is, cancel) our obligations under the Exchange Notes. The court might do so if it finds that when we issued the Exchange Notes, (i) we received less than reasonably equivalent value or fair consideration and (ii) we either (a) were or were rendered insolvent, (b) were left with inadequate capital to conduct our business or (c) believed or reasonably should have believed that we would incur debts beyond our ability to pay. The court could also avoid the Exchange Notes, without regard to the factors described in clauses (i) and (ii) above, if it finds that we issued the Exchange Notes with actual intent to hinder, delay or defraud our creditors.

        Similarly, if one of the guarantors of the Exchange Notes becomes a debtor in a case under the U.S. Bankruptcy Code or encounters other financial difficulty, a court might cancel its Exchange Guarantee if it finds that when such guarantor issued its Exchange Guarantee (or in some jurisdictions, when payments become due under the Exchange Guarantee of such Exchange Notes), factors (i) and (ii) above applied to such guarantor, such guarantor was a defendant in an action for money damages or had a judgment for money damages docketed against it (if, in either case, after final judgment the judgment is unsatisfied), or if it found that such guarantor issued its Exchange Guarantee with actual intent to hinder, delay or defraud its creditors.

        A court could avoid any payment by us or any such guarantor pursuant to the Exchange Notes or the Exchange Guarantee thereof or any realization on the pledge of assets securing the Exchange Notes or the Exchange Guarantees of such Exchange Notes, and require the return of any payment or the return of any realized value to us or such guarantor, as the case may be, or to a fund for the benefit of our or such guarantor's creditors. In addition, under the circumstances described above, a court could subordinate rather than avoid obligations under the Exchange Notes, the Exchange Guarantees or the pledges. If the court were to avoid any Exchange Guarantee, funds may not be available to pay the Exchange Notes from another guarantor thereof or from any other source.

        The test for determining solvency for purposes of the foregoing will vary depending on the law of the jurisdiction being applied. In general, a court would consider an entity insolvent either if the sum of its existing debts exceeds the fair value of all of its property, or its assets' present fair saleable value is less than the amount required to pay the probable liability on its existing debts as they become due. For this analysis, "debts" include contingent and unliquidated debts. If a court avoided our obligations under the Exchange Notes and the obligations of such guarantor under its Exchange Guarantee thereof, holders of the Exchange Notes would cease to be our creditors or creditors of such guarantor and likely have no source from which to recover amounts due under the Exchange Notes. Even if the Exchange Guarantee of such guarantor is not avoided as a fraudulent transfer, a court may subordinate

21

---

Table of Contents

such Exchange Guarantee to such guarantor's other debt. In that event, such Exchange Guarantee would be structurally subordinated to all of such guarantor's other debt.

        The Indenture will limit the liability of each guarantor on its Exchange Guarantee of the Exchange Notes issued thereunder to the maximum amount that such guarantor can incur without risk that its Exchange Guarantee will be subject to avoidance as a fraudulent transfer. This limitation may not protect such Exchange Guarantees from fraudulent transfer challenges or, if it does, the remaining amount due and collectible under the Exchange Guarantees may not suffice, if necessary, to pay the Exchange Notes in full when due.

Any future pledge of collateral may be avoidable in bankruptcy.

        Any future pledge of collateral in favor of the trustee or collateral agent under the Indenture may be avoidable by the pledgor (a debtor in possession) or by its trustee in bankruptcy if certain events or circumstances exist or occur, including, among others, if (i) the pledgor is insolvent at the time of the pledge, (ii) the pledge permits the holders of the Kratos Notes to receive a greater recovery than if the pledge had not been given and (iii) a bankruptcy proceeding in respect of the pledgor is commenced within 90 days following the pledge or the perfection thereof, or, in certain circumstances, a longer period.

The collateral is subject to casualty risks.

        We intend to maintain insurance or otherwise insure against hazards in a manner appropriate and customary for our business. There are, however, certain losses that may be either uninsurable or not economically insurable, in whole or in part. Insurance proceeds may not compensate us fully for our losses. If there is a complete or partial loss of any of the collateral, the insurance proceeds may not be sufficient to satisfy all of the secured obligations, including the Kratos Notes and the Kratos Guarantees secured thereby.

Our ability to repurchase the Kratos Notes upon a change of control may be limited.

        Upon the occurrence of specific change of control events, we will be required to offer to repurchase all outstanding Kratos Notes at 101% of the principal amount, plus accrued and unpaid interest, if any, to the date of repurchase. The lenders under the Revolver will have the right to accelerate the indebtedness thereunder upon a change of control. Any of our future debt agreements may contain a similar provision. However, we may not have sufficient funds at the time of the change of control to make the required repurchase of Kratos Notes or repayment of our other indebtedness. Any of our future debt agreements may contain similar restrictions. If we fail to repurchase any Kratos Notes submitted in a change of control offer, it would constitute an event of default under the Indenture governing the Kratos Notes which would, in turn, constitute an event of default under the Revolver and could constitute an event of default under our other indebtedness, even if the change of control itself would not cause a default. Important corporate events, such as takeovers, recapitalizations or similar transactions, may not constitute a change of control under the Indenture governing the Kratos Notes and thus not permit the holders of the Kratos Notes to require us to repurchase or redeem the Kratos Notes. See "Description of the Exchange Notes—Repurchase Upon Change of Control."

The Kratos Notes may receive a reduced rating in the future, which could cause a decline in the liquidity or market price of the Exchange Notes.

        If in the future one or more rating agencies assigns the Kratos Notes a reduced rating lower than the current rating, the market price of the Kratos Notes may be adversely affected.

If you do not exchange your Original Notes pursuant to this exchange offer, you may never be able to sell your Original Notes.

        It may be difficult for you to sell your Original Notes that are not exchanged in the exchange offer. The Original Notes may not be offered or sold unless they are registered or there are exemptions from the registration requirements under the Securities Act and applicable state securities laws. If you do not tender your Original Notes or if we do not accept some of your Original Notes, those notes will continue to be subject to the transfer and exchange restrictions in:

•

the Indenture;



•

the legend on the Original Notes; and



•

the offering circular relating to the Original Notes.

        The restrictions on transfer of your Original Notes arise because we issued the Original Notes pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws. In general, you may only offer or sell the Original Notes if they are registered under the Securities Act and applicable state securities laws, or offered and sold pursuant to an exemption from such requirements. Holders who do not tender their Original Notes will not have any further registration rights under the registration rights agreement or otherwise, and we do not intend to register the Original Notes under the Securities Act. To the extent Original Notes are tendered and accepted in the exchange offer, the trading market, if any, for the Original Notes would be adversely affected. See "The Exchange Offer—Procedures for Tendering."

There is no active market for the Exchange Notes and if an active trading market does not develop for the Exchange Notes you may not be able to resell them.

        The Exchange Notes are a new issue of securities for which there is currently no trading market. We do not intend to list the Exchange Notes on any national securities exchange or include the Exchange Notes for quotation on any automated dealer quotation system. The initial purchasers of the Stage I Notes indicated that they intend to make a market in the notes; however, they are not obligated to do so and any market-making activities may be discontinued at any time without notice. In addition, market-making activity will be subject to the limits imposed by law. Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the Exchange Notes. Any such disruptions could adversely affect the prices at which the Exchange Notes may be sold.

        Further, even if a market were to exist, the Exchange Notes could trade at prices that may be lower than the initial offering price depending on many factors, including prevailing interest rates, the markets for similar securities, general economic conditions and our financial condition, current stock price, performance and prospects. The liquidity of, and the trading market for, the Exchange Notes may be adversely affected by general declines or disruptions in the market for non-investment grade debt.

Some holders that exchange their Original Notes may be required to comply with registration and prospectus delivery requirements in connection with the sale or transfer of their Exchange Notes.

        Holders that exchange Original Notes in the exchange offer for the purpose of participating in a distribution of the Exchange Notes may be deemed to have received restricted securities and, if so, will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction. Each broker-dealer that receives Exchange Notes for its own account in exchange for Original Notes which were acquired by such broker-dealer as a result of market-making or other trading activities may be deemed to be a statutory underwriter under the

23

Table of Contents

Securities Act and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction. Holders that are required to comply with the registration and prospectus delivery requirements may face additional burdens on the transfer of their Exchange Notes and could incur liability for failure to comply with applicable requirements.

Your Original Notes will not be accepted for exchange if you fail to follow the applicable exchange offer procedures and, as a result, your Original Notes will continue to be subject to existing transfer restrictions and you may not be able to sell them.

        We will not accept your Original Notes for exchange if you do not follow the applicable exchange offer procedures. We will issue Exchange Notes as part of the applicable exchange offer only after timely receipt of your Original Notes, a properly completed and duly executed letter of transmittal and all other required documents. Therefore, if you want to tender your Original Notes, please allow sufficient time to ensure timely delivery. If we do not receive your Original Notes, a properly completed and duly executed letter of transmittal and other required documents by the expiration date of the applicable exchange offer, we will not accept your Original Notes for exchange. We are under no duty to give notification of defects or irregularities with respect to the tenders of Original Notes for exchange. If there are defects or irregularities with respect to your tender of Original Notes, we will not accept your Original Notes for exchange.

Other Risks Related to Kratos

        The entire Federal Government is currently operating under the authority of a Continuing Resolution for the fiscal year ending September 30, 2011, and has suspended certain federal retirement fund payments to finance the nation's general obligations. The failure of the Federal Government to pass a new appropriations bill, extend the Continuing Resolution or increase the nation's debt ceiling could result in a shut down of the government for all nonessential Federal Government services. A shut down of the government for all nonessential Federal Government services could cause the government, government agencies or prime contractors that use Kratos as a subcontractor, to reduce their purchases under existing contracts, to exercise their rights to terminate contracts at-will, to abstain from exercising options to renew contracts, to delay or refrain from making new contract awards, or to delay the payment of Kratos' invoices, any of which could have an adverse effect on Kratos' business, financial condition and results of operations.

        In addition to the foregoing risks, we are, and will continue to be, subject to the risks described in our Annual Report on Form 10-K for the year ended December 26, 2010 and in our subsequent reports on Forms 10-Q and 8-K and other filings with the SEC. All such reports are or will be filed with the SEC and are incorporated by reference into this prospectus. See the section entitled "Where You Can Find More Information" beginning on page 102.

USE OF PROCEEDS

        We will not receive any cash proceeds from the issuance of the Exchange Notes. In consideration for issuing the Exchange Notes as contemplated in this prospectus, we will receive in exchange Original Notes in like principal amount. The Original Notes surrendered in exchange for Exchange Notes will be retired and canceled and cannot be reissued. Issuance of the Exchange Notes will not result in a change in our amount of outstanding debt.

THE EXCHANGE OFFER

Purpose and Effect of the Exchange Offer

        On March 25, 2011, the Stage I Issuer issued $285.0 million aggregate principal amount of the Stage I Notes pursuant to the Stage I Indenture. In connection with the purchase and sale of the Stage I Notes, we entered into a registration rights agreement with the initial purchasers of the Stage I Notes. On April 4, 2011, (i) the Stage I Issuer merged with and into the Company, and the Company assumed all the assets and liabilities of the Stage I Issuer including, pursuant to a supplemental indenture to the Stage I Indenture, all the obligations of the Stage I Issuer under the Stage I Indenture, the Stage I Notes and the related Collateral Agreements and (ii) the Company became the issuer of the Stage I Notes under the Stage I Indenture and pledgor under such Collateral Agreements. In addition, on April 15, 2011, the Company redeemed all of the outstanding Stage I Notes by issuing to each Holder in exchange therefor the Original Notes issued by the Company pursuant to the Indenture in a like principal amount.

Resale of the Exchange Notes

        Based upon an interpretation by the staff of the SEC contained in no-action letters issued to third parties, we believe that you may exchange Original Notes for Exchange Notes in the ordinary course of business. For further information on the SEC's position, see Exxon Capital Holdings Corporation, available May 13, 1988, Morgan Stanley & Co. Incorporated, available June 5, 1991 and Shearman & Sterling, available July 2, 1993, and other interpretive letters to similar effect. You will be allowed to resell Exchange Notes to the public without further registration under the Securities Act and without delivering to purchasers of the Exchange Notes a prospectus that satisfies the requirements of Section 10 of the Securities Act so long as you do not participate, do not intend to participate, and have no arrangement with any person to participate, in a distribution of the Exchange Notes. However, the foregoing does not apply to you if you are: a broker-dealer who purchased the Exchange Notes directly from us to resell pursuant to Rule 144A or any other available exemption under the Securities Act; or you are an "affiliate" of ours within the meaning of Rule 405 under the Securities Act.

        In addition, if you are a broker-dealer, or you acquire Exchange Notes in the exchange offer for the purpose of distributing or participating in the distribution of the Exchange Notes, you cannot rely on the position of the staff of the SEC contained in the no-action letters mentioned above and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction, unless an exemption from registration is otherwise available.

        Each broker-dealer that receives Exchange Notes for its own account in exchange for Original Notes, which the broker-dealer acquired as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the Exchange Notes. The letter of transmittal for use in connection with any such resale will state that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. A broker-dealer may use this prospectus, as it may be amended or supplemented from time to time, in connection with resales of Exchange Notes

received in exchange for Original Notes which the broker-dealer acquired as a result of market-making or other trading activities.

Terms of the Exchange Offer

        Upon the terms and subject to the conditions stated in this prospectus and in the letter of transmittal, we will accept all Original Notes properly tendered and not withdrawn prior to 5:00 p.m. New York City time, on the expiration date. After authentication of the Exchange Notes by the trustee or an authenticating agent, we will issue $1,000 principal amount of Exchange Notes in exchange for each $1,000 principal amount of Original Notes accepted in the exchange offer. Holders may tender some or all of their Original Notes in denominations of $2,000 or any integral multiple of $1,000.

        If you wish to exchange your Original Notes for Exchange Notes in the exchange offer, you will be required to represent that:

•

any Exchange Notes to be received by you will be acquired in the ordinary course of your business;



•

that, at the time of the commencement and consummation of the exchange offer, you have no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Notes in violation of the Securities Act;



•

that you are not our "affiliate" (as defined in Rule 405 promulgated under the Securities Act) or, if you are an affiliate, you will comply with any applicable registration and prospectus delivery requirements;



•

if you are not a broker-dealer, that you are not engaged in, and do not intend to engage in, the distribution of Exchange Notes; and



•

if you are a broker-dealer that will receive Exchange Notes for your own account in exchange for Original Notes that were acquired as a result of market-making or other trading activities, that you will deliver a prospectus in connection with any resale of such Exchange Notes.

        You will make these representations to us by signing or agreeing to be bound by the letter of transmittal.

        Broker-dealers that are receiving Exchange Notes for their own account must have acquired the Original Notes as a result of market-making or other trading activities in order to participate in the exchange offer. Each broker-dealer that receives Exchange Notes for its own account pursuant to this exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of the Exchange Notes during the 180-day period following the completion of the exchange offer, exclusive of any period during which a stop order suspending the effectiveness of the registration statement of which this prospectus is a part is in effect or we have suspended the use of this prospectus. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer during the 180-day period following the closing of the exchange offer in connection with resales of Exchange Notes received in exchange for Original Notes where such Original Notes were acquired by such broker-dealer as a result of market-making or other trading activities. We have agreed that, during the 180-day period following the closing of the exchange offer, we will make this prospectus available to any broker-dealer for use in connection with any such resale. See "Plan of Distribution."

Table of Contents

        The Exchange Notes will evidence the same debt as the Original Notes and will be issued under and entitled to the benefits of the same indenture. The form and terms of the Exchange Notes are identical in all material respects to the form and terms of the Original Notes except that:

•

the Exchange Notes will be issued in a transaction registered under the Securities Act;



•

the Exchange Notes will bear different CUSIP and ISIN numbers from the Original Notes;



•

the Exchange Notes will not be subject to transfer restrictions and, except in limited circumstances, holders of Exchange Notes will have no registration rights; and



•

provisions providing for an increase in the stated interest rate on the Original Notes if the Original Notes are not exchanged for registered Exchange Notes will be eliminated.

        Holders of Original Notes that are not entitled to participate in the exchange offer and holders who do not receive freely tradable Exchange Notes will have, for a period of 180 days following the consummation of the exchange offer, the right to require us to file a registration statement covering resales of their notes. If we do not timely file or cause this resale registration statement to become effective, these holders will be entitled to additional interest.

        As of the date of this prospectus, $285.0 million aggregate principal amount of the Original Notes was outstanding. In connection with the issuance of the Original Notes, we arranged for the Original Notes to be issued and transferable in book-entry form through the facilities of DTC, acting as depositary. The Exchange Notes will also be issuable and transferable in book-entry form through DTC.

        This prospectus, together with the accompanying letter of transmittal, is initially being sent to all registered holders as of the close of business on June 30, 2011. We intend to conduct the exchange offer as required by the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and regulations of the SEC under the Exchange Act, including Rule 14e-1, to the extent applicable.

        The exchange offer is not conditioned upon any minimum aggregate principal amount of Original Notes being tendered, and holders of the Original Notes do not have any appraisal or dissenters' rights under the General Corporation Law of the State of Delaware or under the Indenture in connection with the exchange offer. No governmental approvals or consents must be received to consummate the exchange offer. We shall be considered to have accepted Original Notes tendered according to the procedures in this prospectus when, as and if we have given oral or written notice of acceptance to the exchange agent. See "—Exchange Agent." The exchange agent will act as agent for the tendering holders for the purpose of receiving Exchange Notes from us and delivering Exchange Notes to those holders.

        If any tendered Original Notes are not accepted for exchange because of an invalid tender or the occurrence of other events described in this prospectus, the unaccepted Original Notes will be credited to the holder's account at DTC according to the procedures described below or, in the case of Original Notes tendered by delivery of certificates, certificates for these unaccepted Original Notes will be returned, at our cost, to the tendering holder of the Original Notes, promptly after the expiration date.

        Holders who tender Original Notes in the exchange offer will not be required to pay brokerage commissions or fees or, except as described in the following sentence, transfer taxes related to the exchange of Original Notes in the exchange offer. If you instruct us to register Exchange Notes in the name of, or request that Original Notes not tendered or not accepted in the exchange offer be returned to, a person other than you, you will be responsible for the payment of any applicable transfer

tax. We will pay all charges and expenses, other than applicable taxes, in connection with the exchange offer. See "—Solicitation of Tenders; Fees and Expenses."

        Neither we nor our board of directors makes any recommendation to holders of Original Notes as to whether to tender or refrain from tendering all or any portion of their Original Notes pursuant to the exchange offer. Moreover, no one has been authorized to make any recommendation. Holders of Original Notes must make their own decision whether to tender in the exchange offer and, if so, the amount of Original Notes to tender after reading this prospectus and the letter of transmittal and consulting with their advisors, if any, based on their own financial position and requirements.

Expiration Date; Extensions; Amendments

        The term "expiration date" shall mean 5:00 p.m., New York City time, on July 29, 2011 unless we, in our sole discretion, extend the exchange offer, in which case the term "expiration date" shall mean the latest date to which the exchange offer is extended.

        We expressly reserve the right, in our sole discretion:

•

to delay acceptance of any Original Notes or to terminate the exchange offer and to refuse to accept Original Notes not previously accepted, if any of the conditions described under "—Conditions" shall have occurred and shall not have been waived by us;



•

to extend the expiration date of the exchange offer;



•

to amend the terms of the exchange offer in any manner;



•

to purchase or make offers for any Original Notes that remain outstanding subsequent to the expiration date; and



•

to the extent permitted by applicable law, to purchase Original Notes in the open market, in privately negotiated transactions or otherwise.

        The terms of the purchases or offers described in the fourth and fifth clauses above may differ from the terms of the exchange offer.

        Any delay in acceptance, termination, extension, or amendment will be followed as promptly as practicable by oral or written notice to the exchange agent and by making a public announcement. If the exchange offer is amended in a manner determined by us to constitute a material change, we will promptly disclose the amendment in a manner reasonably calculated to inform the holders.

        Without limiting the manner in which we may choose to make public announcements of any delay in acceptance, termination, extension, or amendment of the exchange offer, we shall have no obligation to publish, advise, or otherwise communicate any public announcement, other than by making a timely press release to an appropriate news agency.

        You are advised that we may extend the exchange offer because some of the holders of the Original Notes do not tender on a timely basis.

Interest on the Exchange Notes

        The Exchange Notes will bear interest from and including June 1, 2011, or, if later, the most recent date on which interest was paid or provided for on the Original Notes surrendered for the Exchange Notes, at a rate of 10% per year. Accordingly, holders of Original Notes that are accepted for exchange will not receive interest that is accrued but unpaid on the Original Notes at the time of

30

Table of Contents

tender. We will pay interest on the Exchange Notes twice a year, on December 1st and June 1st, beginning December 1, 2011.

Procedures for Tendering

        Only a holder may tender his, her or its Original Notes in the exchange offer. Any beneficial owner whose Original Notes are registered in the name of such owner's broker, dealer, commercial bank, trust company or other nominee or are held in book-entry form and who wishes to tender should contact the registered holder promptly and instruct the registered holder to tender on such owner's behalf. If the beneficial owner wishes to tender on his, her or its own behalf, the beneficial owner must, prior to completing and executing the letter of transmittal and delivering the owner's Original Notes, either make appropriate arrangements to register ownership of the Original Notes in the owner's name or obtain a properly completed bond power from the registered holder. The transfer of record ownership may take considerable time and may not be completed prior to the expiration date.

        The tender by a holder will constitute an agreement between the holder, us and the exchange agent according to the terms and subject to the conditions described in this prospectus and in the letter of transmittal.

        A holder who desires to tender Original Notes and who cannot comply with the procedures set forth in this prospectus for tender on a timely basis or whose Original Notes are not immediately available must comply with the procedures for guaranteed delivery set forth below.

        The method of delivery of Original Notes and the letter of transmittal and all other required documents to the exchange agent is at the election and risk of the holders. Delivery of such documents will be deemed made only when actually received by the exchange agent or deemed received under the ATOP procedures described below. In all cases, sufficient time should be allowed to assure delivery to the exchange agent prior to the expiration date. No letter of transmittal or Original Notes should be sent to us. Holders may also request that their respective brokers, dealers, commercial banks, trust companies or nominees effect the tender for holders in each case as described in this prospectus and in the letter of transmittal.

        Original Notes Held in Book-Entry Form.    We understand that the exchange agent will make a request promptly after the date of the prospectus to establish accounts for the Original Notes for the purpose of facilitating the exchange offer, and subject to their establishment, any financial institution that is a participant in DTC may make book-entry delivery of the Original Notes by causing DTC to transfer the Original Notes into the exchange agent's account for the Original Notes using DTC's procedures for transfer.

        The exchange offer is eligible for DTC's ATOP. Accordingly, DTC participants may, instead of physically completing and signing the letter of transmittal and delivering it to the exchange agent, electronically transmit their acceptance of the exchange offer by causing DTC to transfer Original Notes held in book-entry form to the exchange agent in accordance with DTC's ATOP procedures for transfer. DTC will then send a book-entry confirmation, including an agent's message to the exchange agent.

        The term "agent's message" means a message transmitted by DTC, received by the exchange agent and forming part of the book-entry confirmation, which states that DTC has received an express acknowledgment from the participant in DTC tendering Original Notes that are the subject of that book-entry confirmation that the participant has received and agrees to be bound by the terms of the letter of transmittal, and that we may enforce such agreement against such participant. If you use ATOP procedures to tender Original Notes you will not be required to deliver a letter of transmittal to the exchange agent, but you will be bound by its terms just as if you had signed it.

Table of Contents

        If you desire to tender Original Notes held in book-entry form with DTC, the exchange agent must receive, prior to 5:00 p.m. New York City time on the expiration date, at its address set forth in this prospectus, a confirmation of book-entry transfer of the Original Notes into the exchange agent's account at DTC, which is referred to in this prospectus as a "book-entry confirmation," and an agent's message transmitted pursuant to DTC's ATOP procedures. In lieu of transmitting an agent's message pursuant to DTC's ATOP procedures, you may deliver to the exchange agent, prior to 5:00 p.m. New York City time on the expiration date, at the address set forth in this prospectus, a properly completed and validly executed letter of transmittal, or manually signed facsimile thereof, together with any signature guarantees and other documents required by the instructions in the letter of transmittal.

        Original Notes Held in Certificated Form.    For a holder to validly tender Original Notes held in physical or certificated form, the exchange agent must receive, prior to 5:00 p.m. New York City time on the expiration date, at its address set forth in this prospectus:

•

a properly completed and validly executed letter of transmittal, or a manually signed facsimile thereof, together with any signature guarantees and any other documents required by the instructions to the letter of transmittal; and



•

certificates for tendered Original Notes.

        Signatures.    Signatures on a letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed by a member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc., a commercial bank or trust company having an office or correspondent in the United States or an "eligible guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange Act, unless the Original Notes tendered with the letter of transmittal are tendered:

•

by a registered holder who has not requested that Exchange Notes or certificates representing Original Notes not being tendered be issued to a person other than the registered holder, sent to an address other than that of a registered holder or credited to a different account maintained at DTC; or



•

for the account of an institution eligible to guarantee signatures.

        If the letter of transmittal is signed by a person other than the registered holder or DTC participant who is listed as the owner, the Original Notes must be endorsed or accompanied by appropriate bond powers which authorize the person to tender the Original Notes on behalf of the registered holder or DTC participant who is listed as the owner, in either case signed as the name of the registered holder who appears on the Original Notes or the DTC participant who is listed as the owner. If the letter of transmittal or any Original Notes or bond powers are signed or endorsed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, those persons should so indicate when signing and, unless waived by us, submit evidence satisfactory to us of their authority to so act with the letter of transmittal.

        If you tender your Original Notes through ATOP, signatures and signature guarantees are not required.

        Determinations of Validity.    All questions as to the validity, form, eligibility, including time of receipt, acceptance and withdrawal of the tendered Original Notes will be determined by us in our sole discretion. This determination will be final and binding. We reserve the absolute right to reject any and all Original Notes not properly tendered or any Original Notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any irregularities or conditions of tender as to particular Original Notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Original Notes must

32

Table of Contents

be cured within the time we shall determine. Although we intend to notify holders of defects or irregularities related to tenders of Original Notes, neither we, the exchange agent nor any other person shall be under any duty to give notification of defects or irregularities related to tenders of Original Notes, nor shall any of us incur liability for failure to give notification. Tenders of Original Notes will not be considered to have been made until the irregularities have been cured or waived. Any Original Notes received by the exchange agent that we determine are not properly tendered or the tender of which is otherwise rejected by us and as to which the defects or irregularities have not been cured or waived by us will be returned by the exchange agent to the tendering holder unless otherwise provided in the letter of transmittal, promptly following the expiration date.

a written or facsimile transmission of a notice of withdrawal must be received by the exchange agent at its address listed below prior to 5:00 p.m., New York City time, on the expiration date; or

specify the name of the person having deposited the Original Notes to be withdrawn;



•

identify the Original Notes to be withdrawn, including the certificate number or numbers and principal amount of the Original Notes or, in the case of Original Notes transferred by book-entry transfer, the name and number of the account at DTC from which the Original Notes were tendered and the name and number of the account at DTC to be credited;



•

commencement and consummation of the exchange offer, it has no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Notes in violation of the Securities Act; (iii) that it is not our "affiliate" (as defined in Rule 405 promulgated under the Securities Act) or, if it is an affiliate, it will comply with any applicable registration and prospectus delivery requirements; (iv) if such holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of Exchange Notes; and (v) if such holder is a broker-dealer that will receive Exchange Notes for its own account in exchange for Original Notes that were acquired as a result of market-making or other trading activities, that it will deliver a prospectus in connection with any resale of such Exchange Notes.

        If any of these conditions are not met, we will not be required to accept for exchange, or to issue Exchange Notes in exchange for, any Original Notes and may terminate or amend the exchange offer. These conditions are for our sole benefit and may be asserted by us regardless of the circumstances giving rise to any such condition or may be waived by us in whole or in part at any time and from time to time in our discretion. All such conditions must be satisfied or waived by us at or before the expiration date.

Exchange Agent

        Wilmington Trust has been appointed as exchange agent for the exchange offer. In this capacity, the exchange agent has no fiduciary duties and will be acting solely on the basis of our directions. Requests for assistance, requests for additional copies of this prospectus or of the letter of transmittal, and requests for the notice of guaranteed delivery should be directed to the exchange agent. You should send certificates for Original Notes, letters of transmittal and any other required documents to the exchange agent addressed to:

By Regular Mail, Overnight Mail or Courier:
Wilmington Trust FSB
c/o Wilmington Trust Company
Rodney Square North
1100 North Market Street
Wilmington, DE 19890-1626

        Delivery of the letter of transmittal to an address other than as listed above or transmission of instructions via facsimile other than as described above does not constitute a valid delivery of the letter of transmittal.

Solicitation of Tenders; Fees and Expenses

        We will bear the expenses of requesting that holders of Original Notes tender those notes for Exchange Notes. The principal solicitation under the exchange offer is being made by mail. Additional solicitations may be made by our officers and regular employees and our affiliates in person, by telegraph, telephone or telecopier.

        We have not retained any dealer-manager in connection with the exchange offer and will not make any payments to brokers, dealers or other persons soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and will reimburse the exchange agent for its reasonable out-of-pocket costs and expenses in connection with the exchange offer and will indemnify the exchange agent for all losses and claims incurred by it as a result of the exchange offer. We may also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this prospectus, letters of transmittal and related documents to the beneficial owners of the Original Notes and in handling or forwarding tenders for exchange.

35

Table of Contents

        We will pay the expenses to be incurred in connection with the exchange offer, including fees and expenses of the exchange agent and trustee, SEC registration fees, and accounting and legal fees, printing costs, transfer taxes and related fees and expenses.

        You will not be obligated to pay any transfer tax in connection with the exchange, except if you instruct us to register Exchange Notes in the name of, or request that Original Notes not tendered or not accepted in the exchange offer be returned to, a person other than you, you will be responsible for the payment of any applicable transfer tax.

Accounting Treatment

        The Exchange Notes will be recorded at the same carrying value as the Original Notes, as reflected in our accounting records on the date of the exchange. Accordingly, no gain or loss for accounting purposes will be recognized by us upon the closing of the exchange offer. We will amortize the expenses of the exchange offer over the term of the Exchange Notes.

Federal Income Tax Consequences

        The exchange of the Original Notes for the Exchange Notes in the exchange offer will not constitute a taxable event or exchange for U.S. federal income tax purposes, and thus will have no U.S. federal income tax consequences to holders of Original Notes. The Exchange Notes received pursuant to the exchange offer will be treated as a continuation of the Original Notes. Consequently, there will be no change in a holder's adjusted tax basis in the Exchange Notes, and the holder's holding period in the Exchange Notes will be the same as that applicable to the Original Notes. In addition, the U.S. federal income tax consequences of holding and disposing of the Exchange Notes will be the same as those applicable to the Original Notes.

Participation in the Exchange Offer; Untendered Notes

        Participation in the exchange offer is voluntary. Holders of the Original Notes are urged to consult their financial and tax advisors in making their own decisions on what action to take.

        As a result of the making of, and upon acceptance for exchange of all Original Notes tendered under the terms of, this exchange offer, we will have fulfilled a covenant contained in the terms of the registration rights agreement. Holders of the Original Notes who do not tender in the exchange offer will continue to hold their Original Notes and will be entitled to all the rights, and subject to the limitations, applicable to the Original Notes under the Indenture. Holders of Original Notes will no longer be entitled to any rights under the registration rights agreement that by their terms terminate or cease to have further effect as a result of the making of this exchange offer. See "Description of the Exchange Notes." All untendered Original Notes will continue to be subject to the restrictions on transfer described in the Indenture. To the extent that Original Notes are tendered and accepted in the exchange offer, the trading market for untendered Original Notes could be adversely affected. This is because there will probably be many fewer remaining Original Notes outstanding following the exchange, significantly reducing the liquidity of the untendered Original Notes.

        We may in the future seek to acquire untendered Original Notes in the open market or through privately negotiated transactions, through subsequent exchange offers or otherwise. We intend to make any acquisitions of Original Notes following the applicable requirements of the Exchange Act, and the rules and regulations of the SEC under the Exchange Act, including Rule 14e-1, to the extent applicable. We have no present plan to acquire any Original Notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any Original Notes that are not tendered in the exchange offer.

        No appraisals of any Collateral have been prepared in connection with the offering of the Notes.

Table of Contents

        The right of the Collateral Agent to repossess and dispose or otherwise exercise remedies in respect of the Collateral upon the occurrence of an Event of Default is likely to be significantly impaired by applicable bankruptcy law if a bankruptcy proceeding were to be commenced by or against the Company or any Guarantor prior to the Collateral Agent having repossessed and disposed of the Collateral or otherwise completed the exercise of its remedies with respect to the Collateral. Under the Bankruptcy Code, a secured creditor such as the Collateral Agent is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from such debtor, without bankruptcy court approval. Moreover, the Bankruptcy Code permits the debtor to continue to retain and to use collateral even though the debtor is in default under the applicable debt instruments; provided that, under the Bankruptcy Code, the secured creditor is given "adequate protection." The meaning of the term "adequate protection" may vary according to circumstances, but it is intended in general to protect the value of the secured creditor's interest in the collateral securing the Obligations owed to it and may include cash payments or the granting of additional security, if and at such times as the bankruptcy court in its discretion determines, for any diminution in the value of such collateral as a result of the stay of repossession or disposition or any use of the collateral by the debtor during the pendency of the bankruptcy case. In view of the lack of a precise definition of the term "adequate protection" and the broad discretionary powers of a bankruptcy court, it is impossible to predict how long payments under the Notes or the Guarantees could be delayed following commencement of a bankruptcy case, whether or when the Collateral Agent could repossess or dispose of the Collateral or whether or to what extent Holders would be compensated for any delay in payment or loss of value of the Collateral through the requirement of "adequate protection."

        Moreover, the Collateral Agent may need to evaluate the impact of the potential liabilities before determining to foreclose on Collateral consisting of real property because a secured creditor that holds a lien on real property may be held liable under environmental laws for the costs of remediating or preventing release or threatened releases of hazardous substances at such real property. Consequently, the Collateral Agent may decline to foreclose on such Collateral or exercise remedies available if it does not receive indemnification to its satisfaction from the Holders.

        The Collateral Agent's ability to foreclose on the Collateral may be subject to lack of perfection, the consent of third parties, prior liens and practical problems associated with the realization of the Collateral Agent's Lien on the Collateral.

Intercreditor Agreement

        The Collateral Agent, on behalf of itself, the Trustee and the Holders, and the Administrative Agent, on behalf of itself and the Credit Facility Claim Holders, have entered into the Intercreditor Agreement, which, among other things, provides for the following:

        Lien Priorities.    Notwithstanding the date, manner or order of grant, attachment or perfection of any Liens granted to the Collateral Agent, the Trustee or the Holders on the Credit Facility Priority Collateral or of any Liens granted to the Administrative Agent or the Credit Facility Claim Holders on the Credit Facility Priority Collateral and notwithstanding any provision of the UCC or any other applicable law or the Indenture Documents or the Credit Facility Documents or any other circumstance whatsoever, so long as the Discharge of the Credit Facility Claims has not occurred: (a) any Lien on the Credit Facility Priority Collateral now or hereafter held by or on behalf of the Administrative Agent or any Credit Facility Claim Holders or any agent or trustee therefor securing any Credit Facility Claims, will be senior in all respects and prior to any Lien thereon that secures any of the Indenture Obligations; and (b) any Lien on such Credit Facility Priority Collateral now or hereafter held by or on behalf of the Collateral Agent, the Trustee or any Holders or any agent or trustee therefor securing any Indenture Obligations, regardless of how acquired, whether by grant, statute, operation of law, subrogation or otherwise, will be junior and subordinate in all respects to all Liens thereon that secures any Credit Facility Claims. Notwithstanding the date, manner or order of grant, attachment or

41

Table of Contents

perfection of any Liens granted to the Administrative Agent or the Credit Facility Claim Holders on the Notes Priority Collateral or of any Liens granted to the Collateral Agent, the Trustee or the Holders on the Notes Priority Collateral and notwithstanding any provision of the UCC or any other applicable law or the Credit Facility Documents or the Indenture Documents or any other circumstance whatsoever, so long as the Discharge of Indenture Obligations has not occurred: (a) any Lien on the Notes Priority Collateral now or hereafter held by or on behalf of the Collateral Agent, the Trustee or any Holders or any agent or trustee therefor securing any Indenture Obligations, will be senior in all respects and prior to any Lien thereon that secures any of the Credit Facility Claims (except as provided in the definition of Indenture Obligations); and (b) any Lien on such Notes Priority Collateral now or hereafter held by or on behalf of the Administrative Agent or any Credit Facility Claim Holders or any agent or trustee therefor securing any Credit Facility Claims, regardless of how acquired, whether by grant, statute, operation of law, subrogation or otherwise, will be junior and subordinate in all respects to all Liens thereon that secure any Indenture Obligations (except as provided in the definition of Indenture Obligations).

        Prohibition on Contesting Liens.    The Collateral Agent, on behalf of itself, the Trustee and each Holder, and the Administrative Agent, on behalf of itself and each Credit Facility Claim Holder, agrees that it will not and will waive any right to contest or support any other Person in contesting, in any proceeding (including any insolvency or liquidation proceeding), the priority, validity, perfection or enforceability of a Lien held by or on behalf of any of the Credit Facility Claim Holders in the Common Collateral or by or on behalf of any of the Holders in the Common Collateral, as the case may be; provided that nothing in the Intercreditor Agreement shall be construed to prevent or impair the rights of: (a) the Administrative Agent or any Credit Facility Claim Holder to enforce the Intercreditor Agreement, including the priority of the Liens securing the Credit Facility Claims; or (b) the Collateral Agent, the Trustee or any Holder to enforce the Intercreditor Agreement, including the priority of the Liens securing the Indenture Obligations.

        New Liens.    The Administrative Agent, on behalf of itself and each Credit Facility Claim Holder, agrees that, so long as the Discharge of Indenture Obligations has not occurred, it shall not obtain a Lien on any asset or property of the Company or any Guarantor unless the Company or the Administrative Agent shall have provided the Collateral Agent with prior written notice thereof. The Collateral Agent, on behalf of itself, the Trustee and the Holders, agrees that, so long as the Discharge of Credit Facility Claims has not occurred, it shall not obtain a Lien on any asset or property of the Company or any Guarantor unless the Company or the Collateral Agent shall have provided the Administrative Agent with prior written notice thereof. To the extent the foregoing is not complied with for any reason, without limiting any other right or remedy available to the Administrative Agent or the Collateral Agent, as applicable, the Administrative Agent, on behalf of itself and the Credit Facility Claim Holders, and the Collateral Agent, on behalf of itself, the Trustee and the Holders, agrees that any amounts received by or distributed to any of the Credit Facility Claim Holders or the Holders pursuant to or as a result of any Lien granted in contravention of the foregoing shall be subject to "—Application of Proceeds".

        Exercise of Remedies in Respect of Credit Facility Priority Collateral.    So long as the Discharge of Credit Facility Claims has not occurred, whether or not any insolvency or liquidation proceeding has been commenced by or against the Company or any Guarantor, (a) the Collateral Agent, the Trustee and the Holders will not exercise or seek to exercise any rights or remedies (including set-off) with respect to any Credit Facility Priority Collateral that secures any Indenture Obligations, institute any action or proceeding with respect to such rights or remedies (including any action of foreclosure), contest, protest or object to any foreclosure proceeding or action brought by the Administrative Agent or any Credit Facility Claim Holder, the exercise of any right under any Indenture Document or any lockbox agreement, control agreement, blocked account agreement, landlord waiver or bailee's letter or similar agreement or arrangement to which the Collateral Agent, the Trustee or any Holder is a party

Thereafter, the Company may redeem the Notes, at its option, in whole or in part, upon not less than 30 nor more than 60 days' notice, at the following redemption

prices (expressed as percentages of the principal amount thereof) if redeemed during the twelve-month period commencing on June 1, of the year set forth below:

        In addition, the Company must pay accrued and unpaid interest, if any, on the Notes redeemed.

        Optional Redemption Upon Equity Offerings.    At any time, or from time to time, on or prior to June 1, 2013, the Company may, at its option, use an amount not to exceed the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes (which includes the Initial Notes and Additional Notes, if any) originally issued under the Indenture at a redemption price of 110% of the aggregate principal amount thereof, plus accrued and unpaid interest and Additional Interest, thereon, if any, to the date of redemption; provided that:

(1)

at least 65% of the aggregate principal amount of Notes (which includes the Initial Notes and Additional Notes, if any) originally issued under the Indenture remains outstanding immediately after any such redemption; and



(2)

the Company makes such redemption not more than 120 days after the consummation of any such Equity Offering.

        Selection and Notice of Redemption.    In the event that the Company chooses to redeem less than all of the Notes, selection of the Notes for redemption will be made by the Trustee either:

(1)

in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed; or



(2)

if the Notes are not then listed on a national securities exchange, on a pro rata basis, by lot or by such method as the Trustee may reasonably determine is fair and appropriate.

        If a partial redemption is made with the proceeds of an Equity Offering, the Trustee will select the Notes (which will include the Initial Notes and Additional Notes, if any) only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to DTC procedures), unless such method is otherwise prohibited. No Notes of a principal amount of $2,000 or less shall be redeemed in part and Notes of a principal amount in excess of $2,000 may be redeemed in part in multiples of $1,000 only.

        Notice of redemption will be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to the Trustee and each Holder to be redeemed at its registered address. If Notes are to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed. A new Note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in the Global Note (as defined in the Indenture) will be made).

        The Company will pay the redemption price for any Note together with accrued and unpaid interest and Additional Interest thereon through the date of redemption. On and after the redemption date, interest will cease to accrue on Notes or portions thereof called for redemption as long as the Company has deposited with the paying agent funds in satisfaction of the applicable redemption price pursuant to the Indenture.

Mandatory Redemption; Offers to Purchase; Open Market Purchases

        The Company is not required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the Company may be required to offer to purchase the Notes as described under the captions "—Repurchase upon Change of Control" and "—Certain Covenants—Limitation on Asset Sales." The Company may at any time and from time to time purchase Notes in the open market or otherwise.

Repurchase upon Change of Control

        Upon the occurrence of a Change of Control, each Holder will have the right to require that the Company purchase all or a portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder's Notes using immediately available funds pursuant to the offer described below (the "Change of Control Offer"), at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase.

        Within 30 days following the date upon which the Change of Control occurred, the Company must send, by first-class mail, an offer to each Holder, with a copy to the Trustee, which offer shall govern the terms of the Change of Control Offer. Such offer shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed, other than as may be required by law (the "Change of Control Payment Date").

        Holders electing to have a Note purchased pursuant to a Change of Control Offer will be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, to the paying agent at the address specified in the notice prior to the close of business on the third business day prior to the Change of Control Payment Date. If only a portion of a Note is purchased pursuant to a Change of Control Offer, a new Note in a principal amount equal to the portion thereof not purchased will be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be made). Notes (or portions thereof) purchased pursuant to a Change of Control Offer will be cancelled and cannot be reissued.

        The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

        If a Change of Control Offer is made, there can be no assurance that the Company will have available funds sufficient to pay the Change of Control purchase price for all the Notes that might be delivered by Holders seeking to accept the Change of Control Offer. In the event the Company is required to purchase outstanding Notes pursuant to a Change of Control Offer, the Company expects that it would seek third party financing to the extent it does not have available funds to meet its purchase obligations. However, there can be no assurance that the Company would be able to obtain such financing and the terms of the Credit Agreement and/or the Indenture may restrict the ability of the Company to obtain such financing.

        Restrictions in the Indenture described herein on the ability of the Company and its Restricted Subsidiaries to incur additional Indebtedness, to grant Liens on its property, to make Restricted Payments and to make Asset Sales may also make more difficult or discourage a takeover of the Company, whether favored or opposed by the management or the Board of Directors of the Company. Consummation of any such Asset Sales in certain circumstances may require redemption or repurchase of the Notes, and there can be no assurance that the Company or the acquiring party will have

53

Table of Contents

sufficient financial resources to effect such redemption or repurchase. Such restrictions and the restrictions on transactions with Affiliates may, in certain circumstances, make more difficult or discourage any leveraged buyout of the Company or any of its Subsidiaries by the management of the Company. While such restrictions cover a wide variety of arrangements that have traditionally been used to effect highly leveraged transactions, the Indenture may not afford the Holders protection in all circumstances from the adverse aspects of a highly leveraged transaction, reorganization, restructuring, merger, recapitalization or similar transaction.

        One of the events that constitutes a Change of Control under the Indenture is the disposition of "all or substantially all" of the Company's assets under certain circumstances. This term has not been interpreted under New York law (which is the governing law of the Indenture) to represent a specific quantitative test. As a consequence, in the event Holders elect to require the Company to purchase the Notes and the Company elects to contest such election, there can be no assurance as to how a court interpreting New York law would interpret the phrase under such circumstances.

        The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the "Change of Control" provisions of the Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the "Change of Control" provisions of the Indenture by virtue thereof.

Certain Covenants

        The Indenture contains, among others, the following covenants:

        Limitation on Restricted Payments.    The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly:

(1)

declare or pay any dividend or make any distribution (other than dividends or distributions payable in Qualified Capital Stock of the Company and dividends and distributions payable to the Company or another Restricted Subsidiary of the Company) on or in respect of shares of Capital Stock of the Company or its Restricted Subsidiaries to holders of such Capital Stock;



(2)

purchase, redeem or otherwise acquire or retire for value any Capital Stock of the Company or its Restricted Subsidiaries (other than any such Capital Stock held by the Company or any Restricted Subsidiary);



(3)

(4)

make any Investment (other than Permitted Investments);

(each of the foregoing actions set forth in clauses (1), (2), (3) and (4) being referred to as a "Restricted Payment"), if at the time of such Restricted Payment or immediately after giving effect thereto:

(i)

(ii)

the Company is not able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with the covenant described under "—Limitation on Incurrence of Additional Indebtedness and Issuance of Preferred Stock;" or

(D)

the amount for the period subsequent to May 19, 2010 and on or prior to the Reference Date equal to the sum of (i) the net reduction in the Investments (other than Permitted Investments) made by the Company or any of its Restricted Subsidiaries in any Person resulting from repurchases, repayments or redemptions of such Investments by such Person, proceeds realized on the sale of such Investment and proceeds representing the return of capital (excluding dividends and distributions), in each case received by the Company or any of its Restricted Subsidiaries, and (ii) to the extent such Person is an Unrestricted Subsidiary, the portion (proportionate to the Company's equity interest in such Subsidiary) of the Fair Market Value of the net assets of such Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that the foregoing sum shall not exceed, in the case of any such Person or Unrestricted Subsidiary, the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company or any of its Restricted Subsidiaries in such Person or Unrestricted Subsidiary; plus



(E)

100% of the aggregate net cash proceeds received from the exercise by any holder of a convertible note of the Company that has been converted into Qualified Capital Stock of the Company subsequent to May 19, 2010 and on or prior to the Reference Date.

In the case of clause (iii)(B) above, any net cash proceeds from issuances and sales of Qualified Capital Stock of the Company financed directly or indirectly using funds borrowed from the Company or any Subsidiary of the Company, shall be excluded until and to the extent such borrowing is repaid.

        Notwithstanding the foregoing, the provisions set forth in the immediately preceding paragraph do not prohibit:

(1)

the payment of any dividend or other distribution or redemption within 60 days after the date of declaration of such dividend or call for redemption if such payment would have been permitted on the date of declaration or call for redemption;

(6)

        Not later than the date of making any Restricted Payment pursuant to the provisions of the first paragraph described under this covenant and no less frequently than quarterly in the case of all other Restricted Payments, the Company shall deliver to the Trustee an Officers' Certificate stating that such Restricted Payment complies with the Indenture and setting forth in reasonable detail the basis upon which the required calculations were computed, which calculations may be based upon the Company's latest available internal quarterly financial statements.

        Limitation on Incurrence of Additional Indebtedness and Issuance of Preferred Stock.    (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, "incur," which term shall be deemed to include the entry into a committed revolving credit facility or agreement to increase in the amount of the revolving commitments thereunder, in each case, in an aggregate principal amount equal to the aggregate amount of all revolving commitments thereunder at the time of such entry or increase, as the case may be, and for the avoidance of doubt not the extension or issuance of individual loans or letters of credit thereunder) any Indebtedness (other than Permitted Indebtedness), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that if no Default or Event of Default shall have occurred and be continuing at the time of or as a consequence of the incurrence of any such Indebtedness, the Company may incur Indebtedness or issue Disqualified Stock and any of its Restricted Subsidiaries that is or, upon such incurrence, becomes a Guarantor may incur Indebtedness, in each case, if on the date of the incurrence of such Indebtedness or the issuance of such Disqualified Stock, as the case may be, the Consolidated Fixed Charge Coverage Ratio of the Company will be, after giving effect to the incurrence thereof, greater than 2.00 to 1.00. In connection with the Herley Acquisition, the Company incurred Indebtedness, and the Guarantors incurred Indebtedness in the form of Additional Notes and the related guarantees thereof in an aggregate principal amount of $285.0 million, in each case as permitted pursuant to that certain Supplemental Indenture, dated as of February 7, 2011, among the Company, the Guarantors party thereto, the Trustee and the Collateral Agent.

        (b)   The Company will not, and will not permit any of its Domestic Restricted Subsidiaries to, directly or indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated to any other Indebtedness of the Company or such Domestic Restricted Subsidiary unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Obligations of the Company or such Domestic Restricted Subsidiary under (a) in the case of the Company, the Notes and the other Indenture Documents or (b) in the case of such Domestic Restricted Subsidiary, its Guarantee and the other Indenture Documents, in each case, to the same extent and in the same manner as such Indebtedness is subordinated pursuant to subordination provisions that are most favorable to the holders of any other Indebtedness of the Company or such Domestic Restricted Subsidiary.

        Limitation on Asset Sales.    The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1)

the Company or the applicable Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets sold or otherwise disposed;



(2)

at least 75% of the consideration received by the Company or the Restricted Subsidiary, as the case may be, from such Asset Sale is in the form of cash or Cash Equivalents and is received at the time of such disposition; provided that (a) the amount of any liabilities (as shown on the most recent applicable balance sheet) of the Company or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are

assumed by the transferee of any such assets shall be deemed to be cash for purposes of this provision so long as the documents governing such liabilities or the assumption thereof provide that there is no further recourse to the Company or any of its Subsidiaries with respect to such liabilities and (b) the Fair Market Value of any marketable securities received by the Company or any such Restricted Subsidiary in exchange for any such assets that are converted into cash or Cash Equivalents within 60 days after the consummation of such Asset Sale shall be deemed to be cash for purposes of this provision; and

(3)

the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 360 days of receipt thereof either:



(a)

to the extent the property that is subject to such Asset Sale constitutes Credit Facility Priority Collateral, (i) to repay or prepay Indebtedness and other Obligations under the Credit Agreement and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto or (ii) to acquire inventory, documents, contracts, or accounts, chattel paper, instruments or contract rights in respect of any service or sales contracts;



(b)

to make (or enter into a definitive and binding agreement committing to do so within 180 days after the date that is 360 days following the date of receipt of such Net Cash Proceeds) an investment in property, plant, equipment or other non-current assets that replace the properties and assets that were the subject of such Asset Sale or that will be used or useful in a Permitted Business or the acquisition of all of the Capital Stock of a Person engaged in a Permitted Business; or



(c)

a combination of repayment and investment permitted by the foregoing clauses (3)(a) and (3)(b);

provided, that if such Asset Sale is of all or substantially all of the Capital Stock of one or more of the Subsidiaries of the Company and if the Net Cash Proceeds of such Capital Stock are not reinvested in the acquisition of all of the Capital Stock of a Person engaged in a Permitted Business as described in clause (3)(b) above, then the portion of the Net Cash Proceeds attributable to Credit Facility Priority Collateral of such Subsidiaries immediately prior to such sale shall be applied as required by clause (3)(a) above, and the portion of the Net Cash Proceeds attributable to Notes Priority Collateral of such Subsidiaries immediately prior to such sale shall be applied as required by clause (3)(b) above, notwithstanding the fact that such Capital Stock constitutes Notes Priority Collateral.

        Pending the final application of Net Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or invest such Net Cash Proceeds in Cash Equivalents. On the 361^st day after an Asset Sale or such earlier date, if any, as the Board of Directors of the Company or of such Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (3)(a), (3)(b) or (3)(c) of the preceding paragraph (each, a "Net Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds which have not been applied on or before such Net Proceeds Offer Trigger Date as permitted in clauses (3)(a), (3)(b) and (3)(c) of the preceding paragraph (each a "Net Proceeds Offer Amount") shall be applied by the Company or such Restricted Subsidiary to make an offer to purchase (the "Net Proceeds Offer") on a date (the "Net Proceeds Offer Payment Date") not less than 30 nor more than 60 days following the applicable Net Proceeds Offer Trigger Date, from all Holders, the maximum principal amount of Notes that may be purchased with the Net Proceeds Offer Amount at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest thereon, if any, to the date of purchase; provided, however, that if (x) at any time any non-cash consideration received by the Company or any Restricted Subsidiary of the Company, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale

58

Table of Contents

hereunder on the date of such conversion or disposition, as the case may be, and the Net Cash Proceeds thereof shall be applied in accordance with clause (3) of the immediately preceding paragraph and this paragraph and (y) any Net Cash Proceeds are not applied by the date provided in any definitive and binding agreement described under clause (3)(b) of the immediately preceding paragraph (as such date may be extended in accordance with the terms of such definitive agreement, but in any event, to a date no later than 180 days following such 361^st date), such date (as extended, if applicable) shall immediately be deemed to be a "Net Proceeds Trigger Date" and the aggregate amount of such Net Cash Proceeds not applied in accordance with clause (3)(a), (3)(b) or (3)(c), as applicable, by such date shall immediately be deemed to be the "Net Proceeds Offer Amount," and such aggregate amount shall be subject to a Net Proceeds Offer and such Net Cash Proceeds shall be applied in accordance with this paragraph.

        The Company may defer any Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $5.0 million resulting from one or more Asset Sales in which case the accumulation of such amount shall constitute a Net Proceeds Offer Trigger Date (at which time, the entire unutilized Net Proceeds Offer Amount, and not just the amount in excess of $5.0 million, shall be applied as required pursuant to the immediately preceding paragraph). Upon the completion of each Net Proceeds Offer, the Net Proceeds Offer Amount will be reset at zero, and for the avoidance of doubt, if the aggregate principal amount of Notes properly tendered in connection with such Net Proceeds Offer was less than the Net Proceeds Offer Amount, any Net Cash Proceeds relating to, and remaining following the completion of, such Net Proceeds Offer shall no longer constitute Net Cash Proceeds for purposes of this covenant.

        In the event of the transfer of substantially all (but not all) of the property and assets of the Company and its Restricted Subsidiaries as an entirety to a Person in a transaction permitted under "—Merger, Consolidation and Sale of Assets," which transaction does not constitute a Change of Control, the successor entity shall be deemed to have sold the properties and assets of the Company and its Restricted Subsidiaries not so transferred for purposes of this covenant, and shall comply with the provisions of this covenant with respect to such deemed sale as if it constituted an Asset Sale. In addition, the Fair Market Value of such properties and assets of the Company or its Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this covenant.

        Each notice of a Net Proceeds Offer shall be mailed first class, postage prepaid, to the record Holders as shown on the register of Holders within 20 days following the Net Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with the procedures set forth in the Indenture. Upon receiving notice of the Net Proceeds Offer, Holders may elect to tender their Notes in whole or in part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) in exchange for cash. To the extent Holders properly tender Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of tendering Holders will be purchased on a pro rata basis (based on amounts tendered) or on as nearly a pro rata basis as is practicable (subject to DTC procedures). A Net Proceeds Offer shall remain open for a period of 20 business days or such longer period as may be required by law.

        The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the "Asset Sales" provisions of the Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the "Asset Sales" provisions of the Indenture by virtue of such compliance.

(l)

restrictions on cash or other deposits imposed by customers under contracts or other arrangements entered into or agreed to in the ordinary course of business;

        Each Guarantor (other than any Guarantor whose Guarantee is to be released in accordance with the terms of the Guarantee and the Indenture in connection with any transaction complying with the provisions of this covenant and the "—Limitation on Asset Sales" covenant) will not, and the Company will not cause or permit any Guarantor to, consolidate with or merge with or into any Person, other than the Company or any other Guarantor unless:

        All Affiliate Transactions (and each series of related Affiliate Transactions which are similar or part of a common plan) involving aggregate payments or other property with a Fair Market Value in excess of $5.0 million shall be approved by a majority of the members of the Board of Directors of the Company (including a majority of the disinterested members thereof), as the case may be, such approval to be evidenced by a Board Resolution stating that such Board of Directors has determined that such transaction complies with the foregoing provisions and the Company shall deliver an Officers' Certificate to the Trustee certifying that such transactions are in compliance with clause (a)(y) of the preceding paragraph.

(2)

take such actions necessary or advisable to grant to the Collateral Agent for the benefit of the Holders a perfected security interest in the assets of such new Domestic Restricted Subsidiary of the type that would constitute Collateral (which for the avoidance of doubt shall not include any Excluded Assets), subject to the Permitted Liens, including the filing of Uniform

        Conduct of Business.    The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any businesses other than Permitted Businesses.

(1)

all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries (showing in reasonable detail, either on the face of the financial statements or in the footnotes thereto and in "Management's Discussion and Analysis of Financial Condition and Results of Operations", the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company, if any) and, with respect to the annual information only, a report thereon by the Company's certified independent accountants; and



(2)

all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports,

        Notwithstanding the foregoing, the Company may satisfy such requirements prior to the effectiveness of the registration statement contemplated by the Registration Rights Agreement by filing with the SEC such registration statement within the time period required for such filing as specified in the Registration Rights Agreement, to the extent that any such registration statement contains substantially the same information as would be required to be filed by the Company if it were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, and by providing the Trustee and Holders with such Registration Statement (and any amendments thereto) promptly following the filing thereof.

        In addition, following the consummation of the Exchange Offer, whether or not required by the SEC's rules and regulations, the Company will file a copy of all such information and reports with the SEC for public availability within the time periods specified in the SEC's rules and regulations (unless the SEC will not accept such a filing). In addition, the Company has agreed that, prior to the consummation of the Exchange Offer, for so long as any Notes remain outstanding, it will furnish to the Holders upon their request, the information required to be delivered pursuant to Rule 144(A)(d)(4) under the Securities Act.

        Payments for Consent.    The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture, the Notes or any of the Collateral Agreements unless such consideration is offered to be paid or is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Events of Default

(4)

the failure to pay at final maturity (giving effect to any applicable grace periods and any extensions thereof) the principal amount of any Indebtedness of the Company or any Restricted Subsidiary of the Company, or the acceleration of the final stated maturity of any such Indebtedness (which acceleration is not rescinded, annulled or otherwise cured within 20 days from the date of acceleration) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final maturity or which has been accelerated (in each case with respect to which the 20-day period described above has elapsed), aggregates $10.0 million or more at any time;



(5)

one or more judgments in an aggregate amount in excess of $10.0 million shall have been rendered against the Company or any of its Restricted Subsidiaries (other than any judgment as to which a reputable and solvent third party insurer has not disclaimed coverage) and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final and non-appealable;



(6)

certain events of bankruptcy affecting the Company, any of its Significant Subsidiaries or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary;



(7)

a court of competent jurisdiction enters a judgment, decree or order for relief in respect of the Company, any of its Significant Subsidiaries or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary in an involuntary case or proceeding under any Bankruptcy Code, which shall (A) approve as properly filed a petition seeking reorganization, arrangement, adjustment or composition in respect of the Company, such Significant Subsidiary or group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, (B) appoint a Custodian of the Company, such Significant Subsidiary or group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, or for substantially all of its property or (C) order the winding up or liquidation of its affairs; and such judgment, decree or order shall remain unstayed and in effect for a period of sixty (60) days;

invalid or any Guarantor denies its liability under its Guarantee (other than by reason of release of a Guarantor in accordance with the terms of the Indenture); or

(10)

(i) any security interest created by any Collateral Agreement ceases to be in full force and effect (except as permitted by the terms of the Indenture or the Collateral Agreements) or (ii) the breach or repudiation by the Company or any of its Restricted Subsidiaries of any of their obligations under any Collateral Agreement (other than by reason of a release of such obligation or Lien related thereto in accordance with the terms of the Indenture or the Collateral Agreement); provided that, in the case of clauses (i) and (ii), such cessation, breach or repudiation, individually or in the aggregate, results in Collateral having a Fair Market Value in excess of $5.0 million not being subject to a valid, perfected security interest in favor of the Collateral Agent (to the extent required under the Collateral Agreements). For the avoidance of doubt, this clause (10) does not limit or otherwise alter in any manner the remedies available to Holders in clauses (1) through (9) above.

        If an Event of Default (other than an Event of Default specified in clause (6) above with respect to the Company) shall occur and be continuing and has not been waived, the Trustee or the Holders of at least 25% in principal amount of outstanding Notes (which includes the Initial Notes and Additional Notes, if any) may declare the principal of and premium, if any, accrued interest and Additional Interest, if any, on all the Notes to be due and payable by notice in writing to the Company and the Trustee specifying the Event of Default and that it is a "notice of acceleration" (the "Acceleration Notice"), and the same shall become immediately due and payable.

        If an Event of Default specified in clause (6) above with respect to the Company occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest and Additional Interest, if any, on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

        The Indenture provides that, at any time after a declaration of acceleration with respect to the Notes as described in the preceding paragraphs, the Holders of a majority in principal amount of the Notes (which includes the Initial Notes and Additional Notes, if any) may rescind and cancel such declaration and its consequences:

(1)

if the rescission would not conflict with any judgment or decree;



(2)

if all existing Events of Default have been cured or waived except nonpayment of principal, premium, if any, interest or Additional Interest, if any, that has become due solely because of the acceleration;



(3)

to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal and premium, if any, and Additional Interest, if any, which has become due otherwise than by such declaration of acceleration, has been paid or deposited with the Trustee for payment therefor without any restriction on or condition to the application by the Trustee towards such payment;



(4)

if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its reasonable expenses, disbursements and its advances; and



(5)

in the event of the cure or waiver of an Event of Default described in clause (6) of the description above of Events of Default, the Trustee shall have received an Officers' Certificate and an Opinion of Counsel that such Event of Default has been cured or waived.

        No such rescission shall affect any subsequent Default or impair any right consequent thereto.

        The Holders of a majority in principal amount of the Notes (which includes the Initial Notes and Additional Notes, if any) may waive any existing Default or Event of Default under the Indenture, and

68

Table of Contents

its consequences, except a default in the payment of the principal of or premium, if any, interest or Additional Interest, if any, on any Notes.

        Holders may not enforce the Indenture or the Notes except as provided in the Indenture and under the Trust Indenture Act. The Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee an indemnity or security satisfactory to the Trustee. Subject to the provisions of the Indenture and applicable law, the Holders of a majority in aggregate principal amount of the then outstanding Notes have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.

        No past, present or future director, officer, employee, incorporator, or stockholder of the Company or a Guarantor, as such, shall have any liability for any obligations of the Company or the Guarantors under the Notes, the Guarantees or the Indenture or for any claim based on, or in respect of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

        Under the Indenture, the Company is required to provide an Officers' Certificate to the Trustee promptly upon any Officer obtaining knowledge of any Default or Event of Default (provided that such Officers' Certificate shall be provided at least annually whether or not such Officers know of any Default or Event of Default) that has occurred and, if applicable, describe such Default or Event of Default and the status thereof.

Legal Defeasance and Covenant Defeasance

        The Company may, at its option and at any time, elect to have its obligations and the obligations of the Guarantors discharged with respect to the outstanding Notes ("Legal Defeasance"). Such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, except for:

(1)

the rights of Holders to receive payments in respect of the principal of, premium, if any, interest and Additional Interest, if any, on the Notes when such payments are due;



(2)

the Company's obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments;



(3)

the rights, powers, trust, duties and immunities of the Trustee and the Company's obligations in connection therewith; and



(4)

the Legal Defeasance provisions of the Indenture.

        In addition, the Company may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants that are described in the Indenture ("Covenant Defeasance") and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, reorganization and insolvency events) described under "Events of Default" will no longer constitute an Event of Default with respect to the Notes.

        In order to exercise either Legal Defeasance or Covenant Defeasance:

(1)

the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in U.S. dollars, non-callable U.S. government obligations, or a combination thereof, in such amounts and at such times as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest,

if any, on the Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

(2)

in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States confirming that:



(a)

the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or



(b)

since May 19, 2010, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3)

in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States confirming that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;



(4)

no Default or Event of Default shall have occurred and be continuing on the date of such deposit pursuant to clause (1) of this paragraph (except such Default or Event of Default resulting from the failure to comply with "—Certain Covenants—Limitation on Incurrence of Additional Indebtedness and Issuance of Preferred Stock" as a result of the borrowing of funds required to effect such deposit) or insofar as Defaults or Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of such deposit;



(5)

such Legal Defeasance or Covenant Defeasance shall not result in a breach of, or constitute a default under the Indenture or any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;



(6)

the Company shall have delivered to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others;



(7)

the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and



(8)

the Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary qualifications and exclusions) to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940.

Book-Entry, Delivery and Form

        The Exchange Notes will be delivered in the form of one or more "Global Notes." The Global Notes will be deposited with, or on behalf of, DTC and registered in the name of DTC or its nominee, who will be the Global Notes holder. Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to DTC or another nominee of DTC. Investors may hold their beneficial interests in the Global Notes directly through DTC if they are participating organizations or "participants" in such system or indirectly through organizations that are participants in such system. Except in the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to receive physical delivery of certificated notes.

Depository Procedures

        The following description of the operations and procedures of DTC are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them from time to time. We take no responsibility for these operations and procedures and urge investors to contact the system or their participants directly to discuss these matters.

        DTC has advised us that DTC is a limited purpose trust company that was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Participants include securities brokers and dealers, banks, trust companies and clearing corporations and certain other organizations. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

Table of Contents

        We expect that pursuant to procedures established by DTC (i) upon the issuance of the Global Notes, DTC or its custodian will credit, on its internal system, the principal amount of the individual beneficial interests represented by such Global Notes to the respective accounts of persons who have accounts with such depositary and (ii) ownership of beneficial interests in the Global Notes will be shown on, and the transfer of such ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). Such accounts initially will be designated by or on behalf of the initial purchasers and ownership of beneficial interests in the Global Notes will be limited to persons who have accounts with DTC ("participants") or persons who hold interests through participants. Holders may hold their interests in the Global Notes directly through DTC if they are participants in such system, or indirectly through organizations that are participants in such system.

        So long as DTC, or its nominee, is the registered owner or holder, DTC or such nominee, as the case may be, will be considered the sole owner or holder represented by such Global Notes for all purposes under the Indenture under which such Global Notes are issued. No beneficial owner of an interest in the Global Notes will be able to transfer that interest except in accordance with DTC's procedures, in addition to those provided for under the Indenture under which such Global Notes are issued. Payments of the principal of, premium (if any), and interest (including Additional Interest) on, the Global Notes will be made to DTC or its nominee, as the case may be, as the registered owner thereof. None of us, the Trustee, or any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

        We expect that DTC or its nominee, upon receipt of any payment of principal, premium, if any, or interest (including Additional Interest) on the Global Notes, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Notes as shown on the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the Global Notes held through such participants will be governed by standing instructions and customary practice, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants.

        Transfers between participants in DTC will be effected in the ordinary way through DTC's same-day funds system in accordance with DTC rules and will be settled in same day funds. If a holder requires physical delivery of certificated notes for any reason, including to sell Notes to persons in states which require physical delivery of such Notes, or to pledge such securities, such holder must transfer its interest in a Global Note, in accordance with the normal procedures of DTC and with the procedures set forth in the Indenture under which such Global Notes are issued.

        DTC has advised us that it will take any action permitted to be taken by a holder only at the direction of one or more participants to whose account the DTC interests in the Global Notes are credited and only in respect of such portion of the aggregate principal amount of Notes as to which such participant or participants has or have given such direction. However, if there is an event of default under the Indenture under which such Notes are issued, DTC reserves the right to exchange the Global Notes for legended notes in certificated form, and to distribute such notes to its participants.

        Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Notes among participants of DTC, it is under no obligation to perform such procedures, and such procedures may be discontinued at any time. Neither we nor the Trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Certificated Securities

        Subject to certain conditions, any person having a beneficial interest in a Global Note may, upon request to the Trustee, exchange such beneficial interest for notes in the form of certificated securities. Upon any such issuance, the Trustee is required to register such certificated securities in the name of, and cause the same to be delivered to, such person or persons (or the nominee of any thereof). All such certificated notes would be subject to legend requirements. In addition, if:

(1)

we notify the Trustee in writing that DTC is no longer willing or able to act as a depositary and we are unable to locate a qualified successor within 90 days, or



(2)

we, at our option, notify the Trustee in writing that we elect to cause the issuance of notes in the form of certificated securities under the Indenture,

then, upon surrender by the Global Notes holder of its Global Notes, notes in such form will be issued to each person that the Global Notes holder and DTC identify as being the beneficial owner of the related notes.

        Neither we nor the Trustee will be liable for any delay by the Global Notes holder or DTC in identifying the beneficial owners of notes and we and the Trustee may conclusively rely on, and will be protected in relying on, instructions from the Global Notes holder or DTC for all purposes.

Same-Day Settlement and Payment

        The Indenture requires that payments in respect of the Notes represented by the Global Notes (including principal, premium, if any, interest and Additional Interest, if any) be made by wire transfer of immediately available funds to the accounts specified by the Global Notes holder. With respect to certificated securities, we will make all payments of principal, premium, if any, and interest by wire transfer of immediately available funds to the accounts specified by the holders thereof or, if no such account is specified, by mailing a check to each such holder's registered address.

Methods of Receiving Payments on the Notes

        If a holder has given wire transfer instructions to us, we will make all principal, premium and interest payments on those Notes in accordance with those instructions. All other payments on these Notes will be made at the office or agency of the paying agent and registrar within the City and State of New York unless we elect to make interest payments by check mailed to the holders at their address set forth in the register of holders.

Paying Agent and Registrar for the Notes

        The Trustee will initially act as paying agent and registrar for the Notes. We may change the paying agent or registrar without prior notice to the holders of the Notes, and we or any of our subsidiaries may act as paying agent or registrar.

Transfer and Exchange

        A holder may transfer or exchange Notes in accordance with the Indenture. The registrar and the Trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents and we may require a holder to pay any taxes and fees required by law or permitted by the Indenture. We are not required to transfer or exchange any Note selected for redemption. Also, we are not required to transfer or exchange any Note for a period of 15 days before a selection of Notes is to be redeemed.

        The registered holder of a Note will be treated as the owner of it for all purposes.

DESCRIPTION OF CERTAIN INDEBTEDNESS

May 2010 $225.0 Million 10% Senior Secured Note Offering

        On May 19, 2010, we issued $225.0 million in aggregate principal amount of 10% Senior Secured Notes due 2017 in an unregistered offering pursuant to Rule 144A and Regulation S under the Securities Act (the "2010 Notes"). On August 11, 2010, we completed an exchange offer for the 2010 Notes pursuant to a registration rights agreement entered into in connection with the issuance of the 2010 Notes. In the exchange offer, we offered to exchange the 2010 Notes for a like aggregate amount of 10% Senior Secured Notes due June 1, 2017 registered under the Securities Act (referred to elsewhere in this prospectus as the "Existing Kratos Notes"). The Existing Kratos Notes have substantially similar terms as the 2010 Notes, except that the Existing Kratos Notes do not have transfer restrictions or registration rights. The Existing Kratos Notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by us and each of our subsidiaries, as the guarantors thereof. We pay interest on the Existing Kratos Notes semi-annually, in arrears, on June 1 and December 1 of each year, which began on December 1, 2010.

        The Existing Kratos Notes are secured by a lien on substantially all of our assets and the assets of the guarantors thereunder, subject to certain exceptions and permitted liens. The holders of the Existing Kratos Notes have a first priority lien on substantially all of our assets and the guarantors, except accounts receivable, inventories, deposit accounts, securities accounts, cash, securities and general intangibles (other than intellectual property) where the holders of the Existing Kratos Notes have a second priority lien to the $35.0 million credit facility described below.

        The Existing Kratos Notes include customary covenants and events of default as well as a consolidated fixed charge ratio of 2.00 to 1.00 for the incurrence of additional indebtedness. Negative covenants include, among other things, limitations on additional debt, liens, negative pledges, investments, dividends, stock repurchases, asset sales and affiliate transactions. Events of default include, among other events, non-performance of covenants, breach of representations, cross-default to other material debt, bankruptcy, insolvency, material judgments and changes in control. As of December 26, 2010, we were in compliance with the covenants contained in the Existing Kratos Notes.

        On or after June 1, 2014, we may redeem some or all of the Existing Kratos Notes at 105% of the aggregate principal amount of such notes through June 1, 2015, 102.5% of the aggregate principal amount of such notes through June 1, 2016 and 100% of the aggregate principal amount of such notes thereafter, plus accrued and unpaid interest to the date of redemption. Prior to June 1, 2013, we may redeem up to 35% of the aggregate principal amount of the Existing Kratos Notes at 110% of the aggregate principal amount of the Existing Kratos Notes, plus accrued and unpaid interest to the redemption date, with the net cash proceeds of certain equity offerings. In addition, we may, at our option, redeem some or all of the Existing Kratos Notes at any time prior to June 1, 2014, by paying a "make whole" premium, plus accrued and unpaid interest, if any, to the date of redemption.

$35.0 Million Credit Facility

        Concurrent with the completion of the offering of the 2010 Notes, on May 19, 2010, we entered into a Credit and Security Agreement (the "Credit Agreement") with certain lenders and with KeyBank, as administrative agent, lead arranger and sole book runner, for a four year senior secured revolving credit facility in the amount of $25.0 million. The Revolver is secured by a lien on substantially all of our assets and the assets of the guarantors thereunder, subject to certain exceptions and permitted liens. The Revolver has a first priority lien on accounts receivable, inventories, deposit accounts, securities accounts, cash, securities and general intangibles (other than intellectual property). On all other assets, the Revolver has a second priority lien to the Existing Kratos Notes.

97

Table of Contents

        The Revolver will expire on May 18, 2014 and may be increased to $45.0 million. Any increase in the Revolver is subject to the consent of KeyBank and compliance with covenants in the Existing Kratos Notes. The amounts of borrowings that may be made under the Revolver are based on a borrowing base which is comprised of specified percentages of eligible receivables, eligible unbilled receivables and eligible inventory. If the amount of borrowings outstanding under the Revolver exceeds the borrowing base then in effect, we are required to repay such borrowings in an amount sufficient to eliminate such excess. The Revolver includes $10.0 million of availability for letters of credit and $5.0 million of availability for swingline loans.

        We may borrow funds under the Revolver at a base rate based either on LIBOR or a base rate established by KeyBank. Base rate borrowings bear interest at an applicable margin of 1.25% to 2.0% over the base rate (which will be the greater of the prime rate or 0.5% over the federal funds rate, with a floor of 1.0% over one month LIBOR). LIBOR rate borrowings will bear interest at an applicable margin of 3.25% to 4.0% over the LIBOR rate. The applicable margin for base rate borrowings and LIBOR borrowings will depend on the average monthly revolving credit availability. The Revolver also has a commitment fee of 0.75% to 1.0%, depending on the average monthly revolving credit availability.

        Borrowings under the Revolver are subject to mandatory prepayment upon the occurrence of certain events, including the issuance of certain securities, the incurrence of certain debt and the sale or other disposition of certain assets. The Revolver includes customary affirmative and negative covenants and events of default, as well as a financial covenant relating to a minimum fixed charge coverage ratio of 1.25. Negative covenants include, among other limitations, limitations on additional debt, liens, negative pledges, investments, dividends, stock repurchases, asset sales and affiliate transactions. Events of default include, among other events, non-performance of covenants, breach of representations, cross-default to other material debt, bankruptcy and insolvency, material judgments and changes in control.

        On December 13, 2010, we entered into a First Amendment Agreement (the "Amendment Agreement"), with certain lenders and with KeyBank, as administrative agent, lead arranger and sole book runner, which amended the Credit Agreement. Among other things, the Amendment Agreement: (i) increased the amount of the senior secured revolving line of credit from $25.0 million to $35.0 million; (ii) modified the definitions of certain terms contained in the Credit Agreement; (iii) amended certain borrowing covenants under the Credit Agreement to (a) increase the acceptable amount of additional Indebtedness (as defined in the Credit Agreement) attributable to Senior Notes, unsecured Subordinated Indebtedness (both as defined in the Credit Agreement) and other unsecured Indebtedness from $25.0 million to $100.0 million and (b) exempt certain performance based contingent obligations related to prior acquisitions from the borrowing restrictions; and (iv) updated certain schedules to the Credit Agreement. As of December 26, 2010, there were no outstanding borrowings on the Revolver and $2.4 million was outstanding on letters of credit resulting in net availability of $32.6 million. As of December 26, 2010, we were in compliance with the covenants contained in the Revolver.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

        To ensure compliance with Treasury Department Circular 230, you are hereby notified that: (a) any discussion of U.S. federal tax issues contained or referred to herein is not intended or written to be used, and cannot be used, by holders for the purpose of avoiding penalties that may be imposed on them under the Internal Revenue Code of 1986, as amended (the "Code"); (b) such discussion is written in connection with the promotion or marketing of the transactions or matters addressed herein; and (c) holders should seek advice based on their particular circumstances from an independent tax advisor.

        The following is a summary of certain material U.S. federal income tax considerations relating to the exchange of Original Notes for Exchange Notes in the exchange offer. This summary is based on the Code, existing and proposed Treasury Regulations, revenue rulings, administrative interpretations and judicial decisions now in effect, all of which are subject to change possibly with retroactive effect. This summary does not purport to address all U.S. federal income tax considerations that may be relevant to holders in light of their particular circumstances or to holders subject to special tax rules, such as banks, insurance companies or other financial institutions, dealers in securities or foreign currencies, tax-exempt investors, holders subject to the U.S. federal alternative minimum tax, or persons holding the notes as part of a hedging transaction, straddle, conversion transaction, or other integrated transaction.

        We have not sought and we do not expect to seek any ruling from the Internal Revenue Service (the "IRS") or an opinion of counsel with respect to the statements made and the conclusions reached in the following summary. As such, there can be no assurance that the IRS will agree with such statements and conclusions. Thus, all persons that exchange Original Notes for Exchange Notes in the exchange offer are urged to consult their own tax advisors with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign jurisdiction.

        The exchange of the Original Notes for the Exchange Notes in the exchange offer will not constitute a taxable event or exchange for U.S. federal income tax purposes, and thus will have no U.S. federal income tax consequences to holders of Original Notes. The Exchange Notes received pursuant to the exchange offer will be treated as a continuation of the Original Notes. Consequently, there will be no change in a holder's adjusted tax basis in the Exchange Notes, and the holder's holding period in the Exchange Notes will be the same as that applicable to the Original Notes. In addition, the U.S. federal income tax consequences of holding and disposing of the Exchange Notes will be the same as those applicable to the Original Notes.

        The preceding discussion of certain U.S. federal income tax considerations is not tax advice. Each prospective investor should consult its own tax advisor regarding the particular U.S. federal, state, local and foreign tax consequences of exchanging Original Notes for, holding and disposing of Exchange Notes, including the consequences of any proposed change in applicable laws.

PLAN OF DISTRIBUTION

        Each broker-dealer that receives Exchange Notes for its own account in the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of the Exchange Notes. We have agreed that, during the period broker-dealers are required to deliver this prospectus, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Original Notes where such Original Notes were acquired as a result of market-making or other trading activities.

        We will not receive any proceeds from any sale of Exchange Notes by broker-dealers. Exchange notes received by broker-dealers for their own account in the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Notes or a combination of these methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange Notes that were received by it for its own account in the exchange offer and any broker or dealer that participates in a distribution of such Exchange Notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of Exchange Notes and any commissions or concessions received by any such persons may be considered underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

        During the 180-day period following the completion of this exchange offer, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to the exchange offer (including the expenses of one counsel for the holders of the Original Notes), other than dealers' and brokers' discounts, commissions and counsel fees and will indemnify the holders of the Original Notes, including any broker-dealers, against certain liabilities, including liabilities under the Securities Act.
