This prospectus is part of an automatic shelf registration statement that we filed with the Securities and Exchange Commission (the “SEC”), as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”). By using an automatic shelf registration statement, we may, at any time and from time to time, sell senior unsecured notes, including the related guarantees, under this prospectus in one or more offerings in an unlimited amount. As allowed by the SEC rules, this prospectus does not contain all of the information included in the registration statement. For further information, we refer you to the registration statement, including its exhibits. Statements contained in this prospectus about the provisions or contents of any agreement or other document are not necessarily complete and the applicable prospectus supplement may add, update or change the information contained in this prospectus.

This prospectus provides you with a general description of the securities we may offer. Each time we use this prospectus to offer securities, we will provide you with a prospectus supplement that will describe the specific amounts, prices and terms of the securities being offered. The prospectus supplement may also add, update or change information contained in this prospectus. Therefore, if there is any inconsistency between the information in this prospectus and the prospectus supplement, you should rely on the information in the prospectus supplement.

To understand the terms of our securities, you should carefully read this document and the applicable prospectus supplement. Together, they provide the specific terms of the securities we are offering. You should also read the documents we have referred you to under “Where You Can Find More Information” below for information on our company, the risks we face and our financial statements. The registration statement and exhibits can be read at the SEC’s website or at the SEC as described under “Where You Can Find More Information.”

Some of the information included or incorporated by reference in this prospectus and the applicable prospectus supplement concerning our operations, cash flows, financial position, economic performance and financial condition, including in particular, the likelihood of our success in developing and expanding our business and the realization of sales from backlog, include forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act.

Statements that are predictive in nature, that depend upon or refer to events or conditions or that include words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates” and similar expressions are forward-looking statements. Although we believe that these statements are based upon reasonable assumptions, including projections of total sales growth, sales growth from business acquisitions, organic sales growth, consolidated operating margins, total segment operating margins, interest expense, earnings, cash flow, research and development costs, working capital, capital expenditures and other projections, they are subject to several risks and uncertainties, and therefore, it is possible that these statements may not be achieved. Such statements will also be influenced by factors which include, among other things:

In addition, for a discussion of these and other risks and uncertainties that could impair our results of operations or financial condition, see “Part I — Item 1A — Risk Factors” (as it may be updated in our subsequently filed quarterly reports on Form 10-Q) and Note 19 to our audited consolidated financial statements (as it may be updated in our subsequently filed quarterly reports on Form 10-Q), in each case included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, and the risk factor section contained in the applicable prospectus supplement.

Readers of this document are cautioned that our forward-looking statements are not guarantees of future performance and actual results or developments may differ materially from the expectations expressed in the forward-looking statements.

As for the forward-looking statements that relate to future financial results and other projections, actual results will be different due to the inherent uncertainties of estimates, forecasts and projections and may be better or worse than projected and such differences could be material. Given these uncertainties, you should not place any reliance on these forward-looking statements. These forward-looking statements also represent our estimates and assumptions only as of the date that they were made. We expressly disclaim a duty to provide updates to these forward-looking statements, and the estimates and assumptions associated with them, after the date of this filing to reflect events or changes in circumstances or changes in expectations or the occurrence of anticipated events.

L-3 Communications’ telephone number is (212) 697-1111, and its internet address is www.L-3com.com. However, our Web site and information posted on it or connected to it do not constitute a part of this prospectus or any prospectus supplement.

Our business is subject to uncertainties and risks and an investment in our securities involves a high degree of risk. You should carefully consider and evaluate all of the information included and incorporated by reference in this prospectus and any accompanying prospectus supplement, including the risk factors included in the accompanying prospectus supplement and incorporated by reference, as well as any risk factors we may describe in any subsequent periodic reports or information L-3 Holdings and L-3 Communications file with the SEC. It is possible that our business, financial condition, liquidity or results of operations could be materially and adversely affected by any of these risks. In that case, the trading price of our securities could decline and you might lose all or part of the value of your investment.

Unless we otherwise state in the applicable prospectus supplement, we intend to use the net proceeds from the sale of the securities for general corporate purposes. General corporate purposes may include but are not limited to refinancing, repayment, redemption, repurchase or retirement of debt, additions to working capital, capital expenditures, investments in our subsidiaries and possible acquisitions.

The ratio of earnings to fixed charges presented below should be read together with our consolidated financial statements and related notes, “Part II — Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012 and “Part I — Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 29, 2013, which are incorporated herein by reference. In calculating the ratio of earnings to fixed charges, earnings consist of income from continuing operations before income taxes less net income from continuing operations attributable to noncontrolling interests plus fixed charges. Fixed charges consist of interest on indebtedness plus the amortization of bond discounts and deferred debt issuance costs and that portion of lease rental expense representative of the interest element.

The following is a summary of the general terms and conditions of the senior unsecured notes and the related subsidiary guarantees. When we offer to sell a particular series of senior unsecured notes, we will describe the specific terms and conditions of the series in a prospectus supplement to this prospectus. We will also indicate in the applicable prospectus supplement whether the general terms and conditions described in this prospectus apply to the series of senior unsecured notes. For each series of senior unsecured notes, the applicable prospectus supplement for the series may change and supplement the summary below.

We will issue the senior unsecured notes in one or more series under an indenture among L-3 Communications, the subsidiary guarantors from time to time party thereto and The Bank of New York Mellon Trust Company, N.A., as trustee. You should also read the indenture under which the senior unsecured notes are to be issued. We have filed the indenture governing the senior unsecured notes with the SEC as an exhibit to the registration statement of which this prospectus is a part.

All capitalized terms have the meanings specified in the indenture. In this section, the “Company,” “we,” “us” and “our” refer only to L-3 Communications Corporation, but not to any of its subsidiaries.

The indenture does not limit the amount of senior unsecured notes that we may issue and permits us to issue senior unsecured notes in one or more series. All senior unsecured notes of one series need not be issued at the same time, and, unless otherwise provided, any series may be reopened, without the consent of the holders of the senior unsecured notes of that series, for issuances of additional senior unsecured notes of that series. Such additional senior unsecured notes of any series will have the same terms as, and rank equally and ratably with, the existing senior unsecured notes of such series in all respects (except for the issue date and, if applicable, the payment of interest accruing prior to the issue date of such additional notes and the date of the first payment of interest following the issue date of such additional notes) and will be consolidated and form a single series with, and will have the same terms as to ranking, redemption, waivers, amendments or otherwise, as the existing senior unsecured notes of such series, and will vote together as one class on all matters with respect to such series of senior unsecured notes. The indenture provides that we may issue senior unsecured notes up to the principal amount that we may authorize and that such senior unsecured notes may be in any currency or currency unit that we may designate. Except for the limitations on liens, sales and leaseback transactions, consolidation, merger and sale of all or substantially all of our assets contained in the indenture and a covenant relating to future guarantors, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any senior unsecured notes protection against changes in our operations, financial condition or transactions involving us.

We may issue the senior unsecured notes issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These senior unsecured notes, as well as other senior unsecured notes that are not issued at a discount, may be issued with “original issue discount,” or “OID,” for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the senior unsecured notes. Certain U.S. federal income tax considerations applicable to senior unsecured notes issued with OID will be described in more detail in the applicable prospectus supplement.

The applicable prospectus supplement for a series of senior unsecured notes that we issue will describe, among other things, the following terms of the offered senior unsecured notes:

The applicable prospectus supplement may discuss certain U.S. federal income and estate tax considerations for holders of any senior unsecured notes, if any, and the securities exchange or quotation system on which any senior unsecured notes are to be listed or quoted, if any.

We expect most senior unsecured notes to be issued in fully registered form without coupons and in denominations of $2,000 and any integral multiples of $1,000 in excess thereof.

Unless otherwise specified in the applicable prospectus supplement, the Company’s payment obligations under the senior unsecured notes will be jointly and severally guaranteed (the “Subsidiary Guarantees”) by all of the Company’s current and future Domestic Subsidiaries that guarantee other Indebtedness of the Company. The obligations of each Guarantor under its Subsidiary Guarantee will be limited as necessary to prevent that Subsidiary Guarantee from constituting a fraudulent conveyance under applicable law. The Subsidiary Guarantee of each Guarantor will be effectively subordinated to the extent of the value of the collateral securing the other guarantees or Indebtedness of such Guarantor, if such guarantees or Indebtedness are secured. Upon the release of all guarantees by a Guarantor under all then outstanding Indebtedness of the Company (other than the senior unsecured notes), the Subsidiary Guarantee of that Guarantor will automatically and unconditionally be released and discharged, without any further action required by such Guarantor or the trustee. If any former Guarantor thereafter guarantees any Indebtedness of the Company (other than the senior unsecured notes), then that former Guarantor (to the extent it is still a Domestic Subsidiary) will again guarantee the senior unsecured notes on the terms and conditions set forth in the indenture. In addition, the Subsidiary Guarantee of any Guarantor will be automatically and unconditionally released and discharged, without any further action required by such Guarantor or the trustee, if the senior unsecured notes are defeased or at any time such Guarantor is no longer a Domestic Subsidiary.

The indenture will provide that the Company may not, directly or indirectly, consolidate or merge with or into (whether or not the Company is the surviving entity), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to another Person unless:

(1) the Company is the surviving or continuing corporation or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is a corporation, partnership, limited liability company, trust or other entity organized or existing under the laws of the United States, any state thereof or the District of Columbia;

(2) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made (if other than the Company) assumes all the obligations of the Company under the senior unsecured notes and the indenture pursuant to agreements reasonably satisfactory to the trustee; and

In the case of any such consolidation, merger, sale, transfer or other conveyance in a transaction in which there is a successor Person, the successor Person will succeed to, and be substituted for, the Company under the indenture and, subject to the terms of the indenture, the Company will be released from the obligation to pay principal and interest on the senior unsecured notes and all obligations under the indenture.

(a) a merger of the Company with an affiliate solely for the purpose of reincorporating the Company in another jurisdiction; or

(b) any consolidation or merger, or any sale, assignment, transfer, conveyance, lease or other disposition of assets between or among the Company and its subsidiaries.

Unless otherwise specified in the applicable prospectus supplement, the term “Event of Default,” when used in the indenture with respect to any series of senior unsecured notes means any of the following:

(1) default for 30 days in the payment when due of interest on the senior unsecured notes of that series;

(2) default in payment when due of the principal of or premium, if any, on the senior unsecured notes of that series;

(3) failure to make sinking fund payments, if any, when due in respect of that series;

(4) failure by the Company to comply with the provisions described under the caption “— Merger, Consolidation or Sale of Assets”;

(5) failure by the Company to comply with any of its other agreements in the indenture (other than an agreement that has been included in the indenture solely for the benefit of a series of senior unsecured notes other than that series) for 90 days after written notice is received by the Company and the trustee from the holders of at least 25% in aggregate principal amount of senior unsecured notes of that series then outstanding;

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness of the Company or any of its Subsidiaries (or the payment of which is guaranteed by the Company or any of its Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the Issue Date, which default relates to a payment at final maturity or results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of such Indebtedness, together with the principal amount of all other Indebtedness that is not paid at final maturity or the maturity of which has been so accelerated, aggregates $100.0 million or more;

(7) failure by the Company or any of its Subsidiaries to pay final judgments aggregating in excess of $100.0 million, which judgments are not paid, discharged or stayed for a period of 60 days;

(8) certain events of bankruptcy or insolvency with respect to the Company or any of its Significant Subsidiaries;

(9) except as permitted by the indenture, any Subsidiary Guarantee of a Significant Subsidiary is held in any judicial proceeding to be unenforceable or invalid; and

(10) any other Event of Default provided in the applicable officers’ certificate, resolution of our board of directors or the supplemental indenture under which we issue a series of senior unsecured notes.

An Event of Default for a particular series of senior unsecured notes does not necessarily constitute an Event of Default for any other series of senior unsecured notes issued under the indenture.

If an Event of Default with respect to any series of senior unsecured notes occurs and is continuing (other than an Event of Default relating to certain events of bankruptcy or insolvency with respect to the Company), then either the trustee for such series or the holders of 25% in principal amount of the outstanding senior unsecured notes of such series, by notice in writing, may declare the principal amount (or, if the senior unsecured notes are discount securities, that portion of the principal amount as may be specified in the terms of that series) of and accrued and unpaid interest, if any, on all of the senior unsecured notes of such series to be due and payable immediately. We refer you to the prospectus supplement relating to any series of senior unsecured notes that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The holders of a majority in principal amount of the senior unsecured notes of each affected series may, after satisfying certain conditions, rescind and annul any of the above-described declarations and consequences involving such series.

If an Event of Default relating to certain events of bankruptcy or insolvency with respect to the Company occurs and is continuing, then the principal amount (or, if the senior unsecured notes are discount securities, that portion of the principal amount as may be specified in the terms of that series) of and accrued and unpaid interest, if any, on all of the senior unsecured notes outstanding will automatically become due and payable immediately, without any declaration or other act by the trustee or any holder.

The indenture imposes limitations on suits brought by holders of senior unsecured notes against us. Except for actions for payment of overdue principal or interest, no holder of senior unsecured notes of any series may institute any action against us under the indenture unless:

The Company is required to deliver to the trustee annually a statement regarding compliance with the indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the trustee a statement specifying such Default or Event of Default.

Except as otherwise specified in the applicable prospectus supplement, the indenture will provide that the Company will not, and will not permit any of its Wholly Owned Domestic Subsidiaries to, create, incur, assume or permit to exist any Lien (except Permitted Liens) on (1) any Principal Property or (2) the capital stock of any Subsidiary, in each case to secure Indebtedness of the Company, any Subsidiary of the Company or any other Person, unless the senior unsecured notes are secured, equally and ratably with such other Indebtedness (or on a senior basis if the obligations so secured are subordinated Indebtedness), for so long as such other Indebtedness is so secured. Any Lien that is granted to secure the senior unsecured notes under this covenant shall be automatically released and discharged at the same time as the release of the Lien that gave rise to the obligation to secure the senior unsecured notes under this covenant.

“Permitted Liens” means, with respect to each series of senior unsecured notes:

(1) Liens securing Indebtedness of the Company or any of its Subsidiaries, which Indebtedness exists on the Issue Date;

(2) Liens securing Indebtedness of any Person that (a) is acquired by the Company or any of its Subsidiaries after the Issue Date, (b) is merged or amalgamated with or into the Company or any of its Subsidiaries after the Issue Date or (c) becomes consolidated in the financial statements of the Company or any of its Subsidiaries after the Issue Date in accordance with GAAP; provided, however, that in each case contemplated by this clause (2), such Indebtedness was not incurred in contemplation of such acquisition, merger, amalgamation or consolidation and is only secured by Liens on the capital stock and assets of, the Person (and Subsidiaries of the Person) acquired by, or merged or amalgamated with or into, or consolidated in the financial statements of, the Company or any of its Subsidiaries;

(3) Liens securing Indebtedness (including assumed Indebtedness) of the Company or any of its Subsidiaries incurred to finance (whether prior to or within 365 days after) the acquisition, construction or improvement of assets (whether through the direct purchase of assets or through the purchase of the capital stock of any Person owning such assets or through an acquisition of any such Person by merger); provided, however, that such Indebtedness is only secured by Liens on the capital stock and assets acquired, constructed or improved in connection with such financing (including the capital stock and assets of any Subsidiary of any such acquired Person);

(4) Liens to secure any extension, renewal, refinancing or refunding (or successive extensions, renewals, refinancings or refundings), in whole or in part, of any Indebtedness secured by Liens referred to in clauses (1)-(3) above or clause (10) below or Liens created in connection with any amendment, consent or waiver relating to such Indebtedness, so long as such Lien is limited to all or part of substantially the same property which secured the Lien extended, renewed or replaced, the amount of Indebtedness secured is not increased (other than by the amount equal to any costs and expenses (including any premiums, fees or penalties) incurred in connection with any extension, renewal, refinancing or refunding) and the Indebtedness so secured does not exceed the fair market value (as determined by the Company’s board of directors) of the assets subject to such Liens at the time of such extension, renewal, refinancing or refunding, or such amendment, consent or waiver, as the case may be;

(5) Liens to secure intercompany Indebtedness of the Company or any of its Subsidiaries to the Company or any of its Subsidiaries;

(6) Liens to secure the performance of statutory obligations, insurance, surety or appeal bonds, workers compensation obligations, performance bonds or other obligations of a like nature incurred in the ordinary course of business (including Liens to secure letters of credit and reimbursement obligations with respect thereto issued to assure payment of such obligations);

(7) Liens created for the benefit of (or to secure) such series of senior unsecured notes (or the related Subsidiary Guarantees);

(9) Liens for taxes, assessments or governmental charges or claims that are not yet delinquent or that are being contested in good faith by appropriate proceedings promptly instituted and diligently concluded, provided that any reserve or other appropriate provision as is required in conformity with GAAP has been made therefor; and

(10) other Liens, in addition to those permitted in clauses (1) through (9) above, securing Indebtedness having an aggregate principal amount (including all Indebtedness incurred pursuant to clause (4) above to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (10)), measured as of the date of the incurrence of any such Indebtedness (giving pro forma effect to the application of the proceeds therefrom and any transaction in connection with which such Indebtedness is being incurred), taken together with the amount of all Attributable Debt of the Company and its Subsidiaries at that time outstanding relating to Sale and Leaseback Transactions permitted under the covenant described below under the caption “— Limitation on Sale and Leaseback Transactions,” not to exceed the greater of (a) 15% of the Company’s Consolidated Net Tangible Assets measured as of the date of the incurrence of any such Indebtedness (giving pro forma effect to the application of the proceeds therefrom and any transaction in connection with which such Indebtedness is being incurred) or (b) $1.5 billion.

For purposes of clause (10) of this definition of Permitted Liens, (a) with respect to any revolving credit facility secured by a Lien, the full amount of Indebtedness that may be borrowed thereunder will be deemed to be incurred at the time any revolving credit commitment thereunder is first extended or increased and will not be deemed to be incurred when such revolving credit facility is drawn upon and (b) if a Lien of the Company or any of its Wholly Owned Domestic Subsidiaries is granted to secure Indebtedness that was previously unsecured, such Indebtedness will be deemed to be incurred as of the date such Indebtedness is secured.

Except as otherwise specified in the applicable prospectus supplement, the Company will not, and will not permit any of its Subsidiaries to, enter into any arrangement with any other Person pursuant to which the Company or any of its Subsidiaries leases any property that has been or is to be sold or transferred by the Company or the Subsidiary to such other Person (a “Sale and Leaseback Transaction”), except that a Sale and Leaseback Transaction is permitted if the Company or such Subsidiary would be entitled to incur Indebtedness secured by a Lien on the property to be leased (without equally and ratably securing the senior unsecured notes) in an aggregate principal amount equal to the Attributable Debt with respect to such Sale and Leaseback Transaction.

In addition, the following Sale and Leaseback Transactions are not subject to the limitation above and the provisions described in “— Limitation on Liens” above:

(1) temporary leases for a term, including renewals at the option of the lessee, of not more than three years;

(2) leases between only the Company and a Subsidiary of the Company or only between Subsidiaries of the Company;

(3) leases where the proceeds from the sale of the subject property are at least equal to the fair market value (as determined in good faith by the Company) of the subject property and the Company applies an amount equal to the net proceeds of the sale to the retirement of long-term Indebtedness or to the purchase of other property or equipment used or useful in its business, within 270 days of the effective date of such sale; provided that in lieu of applying such amount to the retirement of long-term Indebtedness, the Company may deliver senior unsecured notes or other debt securities to the applicable trustee for cancellation, such senior unsecured notes or other debt securities to be credited at the cost thereof to the Company; and

(4) leases of property executed by the time of, or within 270 days after the latest of, the acquisition, the completion of construction or improvement, or the commencement of commercial operation, of the subject property.

Unless otherwise specified in the applicable prospectus supplement, the indenture will provide that no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person (except the Company or another Guarantor) unless:

(1) subject to the provisions of the following paragraph, the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) assumes all the obligations of such Guarantor pursuant to a supplemental indenture in form and substance reasonably satisfactory to the trustee, under the senior unsecured notes and the indenture; and

(2) immediately after giving effect to such transaction, no Default or Event of Default exists.

The indenture will provide that in the event of a sale or other disposition of all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of stock of any Guarantor such that the Guarantor is no longer a Subsidiary of the Company, then such Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise) or the corporation acquiring the property (in the event of a sale or other disposition of all of the assets of such Guarantor) will be automatically and unconditionally released and relieved of any obligations under its Subsidiary Guarantee, without any actions required on the part of the Guarantor or trustee.

The foregoing notwithstanding, a Guarantor will be automatically and unconditionally released and discharged from all of its obligations under the indenture and its Subsidiary Guarantee upon defeasance or if such Guarantor is released from its guarantees of all other Indebtedness of the Company, without any actions required on the part of the Guarantor or trustee.

Unless otherwise stated in the applicable prospectus supplement, each senior unsecured note will be represented by either one or more global securities registered in the name of The Depository Trust Company, as depositary, or a nominee, or a certificate issued in definitive registered form as set forth in the applicable prospectus supplement. Except as set forth under the subheading “— Global Senior Unsecured Notes and Book-Entry System” below, book-entry senior unsecured notes will not be issuable in certificated form.

Certificated Senior Unsecured Notes. You may transfer or exchange certificated senior unsecured notes at any office we maintain for this purpose in accordance with the terms of the indenture. No service charge will be made for any transfer or exchange of certificated senior unsecured notes, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange.

You may effect the transfer of certificated senior unsecured notes and the right to receive the principal of, premium, if any, and interest, if any, on certificated senior unsecured notes only by surrendering the certificate representing those certificated senior unsecured notes and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

Global Senior Unsecured Notes and Book-Entry System. Each global debt security representing book-entry senior unsecured notes will be deposited with, or on behalf of, the depositary, and registered in the name of the depositary or a nominee of the depositary.

We anticipate that the depositary will follow the following procedures with respect to book-entry senior unsecured notes.

Ownership of beneficial interests in book-entry senior unsecured notes will be limited to persons that have accounts with the depositary for the related global debt security, which we refer to as participants, or persons that may hold interests through participants. Upon the issuance of a global debt security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal amounts of the book-entry senior unsecured notes represented by such global debt security beneficially owned by such participants. The accounts to be credited will be designated by any dealers, underwriters or agents participating in the distribution of the book-entry senior unsecured notes. Ownership of book-entry senior unsecured notes will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by the depositary for the related global debt security (with respect to interests of participants) and on the records of participants (with respect to interests of persons holding through participants). The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. These laws may impair the ability to own, transfer or pledge beneficial interests in book-entry senior unsecured notes.

So long as the depositary for a global debt security, or its nominee, is the registered owner of that global debt security, the depositary or its nominee, as the case may be, will be considered the sole owner or holder of the book-entry senior unsecured notes represented by such global debt security for all purposes under the indenture. Except as described below, beneficial owners of book-entry senior unsecured notes will not be entitled to have securities registered in their names, will not receive or be entitled to receive physical delivery of a certificate in definitive form representing securities and will not be considered the owners or holders of those securities under the indenture. Accordingly, each person beneficially owning book-entry senior unsecured notes must rely on the procedures of the depositary for the related global debt security and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the indenture.

We understand, however, that under existing industry practice, the depositary will authorize the persons on whose behalf it holds a global debt security to exercise certain rights of holders of senior unsecured notes, and the indenture provides that we, the trustee and our respective agents will treat as the holder of a debt security the persons specified in a written statement of the depositary with respect to that global debt security for purposes of obtaining any consents, declarations, waivers or directions required to be given by holders of the senior unsecured notes pursuant to the indenture.

We will make payments of principal of, premium, if any, and interest, if any, on book-entry senior unsecured notes to the depositary or its nominee, as the case may be, as the registered holder of the related global debt security. We, the trustee and any other agent of ours or agent of the trustee will not have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global debt security or for maintaining, supervising or reviewing any records relating to beneficial ownership interests.

We expect that the depositary, upon receipt of any payment of principal of, premium, if any, or interest, if any, on a global debt security, will immediately credit participants’ accounts with payments in amounts proportionate to the respective amounts of book-entry senior unsecured notes held by each participant as shown on the records of such depositary. We also expect that payments by participants to owners of beneficial interests in book-entry senior unsecured notes held through those participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

We will issue certificated senior unsecured notes in exchange for each global debt security if the depositary is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed

by us within 90 days. In addition, we may at any time and in our sole discretion determine not to have the book-entry senior unsecured notes of any series represented by one or more global senior unsecured notes and, in that event, will issue certificated senior unsecured notes in exchange for the global senior unsecured notes of that series. Global senior unsecured notes will also be exchangeable by the holders for certificated senior unsecured notes if an Event of Default with respect to the book-entry senior unsecured notes represented by those global senior unsecured notes has occurred and is continuing. Any certificated senior unsecured notes issued in exchange for a global debt security will be registered in such name or names as the depositary shall instruct the trustee. We expect that such instructions will be based upon directions received by the depositary from participants with respect to ownership of book-entry senior unsecured notes relating to such global debt security.

We have obtained the foregoing information concerning the depositary and the depositary’s book-entry system from sources we believe to be reliable, but we take no responsibility for the accuracy of this information.

Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of senior unsecured notes and as described in the applicable supplement, we may be discharged from any and all obligations in respect of the senior unsecured notes of any series (except for certain obligations to register the transfer or exchange of senior unsecured notes of such series, to replace stolen, lost or mutilated senior unsecured notes of such series, and to maintain paying agencies and certain provisions relating to the treatment of funds held by paying agents). We will be so discharged upon the deposit with the trustee, in trust, of cash, U.S. government obligations or foreign government obligations, or a combination thereof, in such amounts as will be sufficient in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants to pay and discharge each installment of principal, premium, if any, and interest, if any, on and any mandatory sinking fund payments in respect of the senior unsecured notes of that series on the stated maturity or applicable redemption date of those payments in accordance with the terms of the indenture and those senior unsecured notes.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the senior unsecured notes of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred.

Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of senior unsecured notes and as described in the applicable supplement, upon compliance with certain conditions:

Covenant Defeasance and Events of Default. In the event we exercise our option to effect covenant defeasance with respect to any series of senior unsecured notes and the senior unsecured notes of that series are declared due and payable because of the occurrence of any Event of Default, the amount of money and/or U.S. government obligations or foreign government obligations on deposit with the trustee will be sufficient to pay amounts due on the senior unsecured notes of that series at the time of their stated maturity but may not be sufficient to pay amounts due on the senior unsecured notes of that series at the time of the acceleration resulting from the Event of Default. However, we shall remain liable for those payments.

The indenture provides that we and the trustee may enter into supplemental indentures without the consent of the holders of any series of senior unsecured notes to:

The indenture also provides that we and the trustee may, with the consent of the holders of at least a majority in principal amount of senior unsecured notes of a series then outstanding and affected, add any provisions to, or change in any manner, eliminate any of the provisions of the indenture with respect to such series or modify in any manner the rights of the holders of the senior unsecured notes of such series. We and the trustee may not, however, without the consent of the holder of each outstanding senior unsecured note affected thereby (with respect to any senior unsecured notes held by such non-consenting holder):

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding senior unsecured notes of any series may on behalf of the holders of all senior unsecured notes of that series waive our compliance with provisions of the indenture. The holders of a majority in principal amount of the outstanding senior unsecured notes of any series may on behalf of the holders of all the senior unsecured notes of such series waive any past default under the indenture with respect to that series and its consequences, except a continuing default or Event of Default in the payment of the principal of, premium, if any, or interest, if any, on any senior unsecured note of that series or in respect of a covenant or provision which cannot be modified or amended without the consent of the holder of each outstanding senior unsecured note of the series affected; provided, however, that the holders of a majority in principal amount of the outstanding senior unsecured notes of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration.

No director, officer, employee, incorporator or stockholder of the Company or any Subsidiary of the Company, as such, will have any liability for any obligations of the Company or any Subsidiary of the Company under the senior unsecured notes, the Subsidiary Guarantees or the indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of senior unsecured notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the senior unsecured notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

The indenture, the Subsidiary Guarantees and the senior unsecured notes will be governed by, and construed in accordance with, the laws of the State of New York.

The indenture contains certain limitations on the rights of the trustee, should it become a creditor of the Company, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign, in each case to the extent required by law.

The holders of a majority in aggregate principal amount of the then outstanding notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions. The indenture provides that if an Event of Default occurs and is continuing, the trustee will be required, in the exercise of its power, to use the degree of care and skill of a prudent person in the conduct of such person’s affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any holder of senior unsecured notes, unless such holder offers the trustee security and indemnity satisfactory to it against any loss, liability or expense. We and our subsidiaries from time to time maintain ordinary banking relationships and credit facilities with The Bank of New York Mellon Corporation and its affiliates.

Unless otherwise specified in the applicable prospectus supplement, set forth below are certain defined terms used in the indenture. Reference is made to the indenture and the applicable prospectus supplement for a full disclosure of all such terms, as well as any other capitalized terms used herein for which no definition is provided.

“Consolidated Net Tangible Assets” of any Person as of any date means the total assets of such Person and its Subsidiaries as of the most recent fiscal quarter end for which a consolidated balance sheet of such Person and its Subsidiaries is available as of that date, minus all current liabilities of such Person and its Subsidiaries reflected on such balance sheet and minus total goodwill and other intangible assets of such Person and its Subsidiaries reflected on such balance sheet, all calculated on a consolidated basis in accordance with GAAP.

“Default” means any event that is, or with the passage of time or the giving of notice or both would be, an Event of Default.

For the avoidance of doubt, bankers’ acceptances and obligations of a Person under currency exchange or interest rate swap agreements (or other agreements or arrangements designed to protect such Person against fluctuations in currency exchange rates or interest rates) are not Indebtedness.

“Issue Date” means, with respect to each series of senior unsecured notes, the date such series of senior unsecured notes are issued.

“Lien” means any mortgage, lien, pledge, charge, security interest or other encumbrance of any kind, whether or not filed, recorded or otherwise perfected under applicable law, including any conditional sale or other title retention agreement, any lease in the nature thereof, any option or other agreement to sell or give a security interest in and any filing of or agreement to give any financing statement under the Uniform Commercial Code (or equivalent statute) of any jurisdiction.

“Principal Property” means any building, structure or other facility located within the United States (other than its territories and possessions) and owned by the Company or any Wholly Owned Domestic Subsidiary, the book value of which is not less than 0.5% of the Company’s Consolidated Net Tangible Assets. For purposes of this definition, book value will be measured at the time the relevant Lien is being created or, in the case of any Lien incurred pursuant to clause (10) of the definition of “Permitted Liens”, at the time the relevant secured Indebtedness is deemed to be incurred.

The term “Principal Property,” as defined above, will not include any of the assets of our Subsidiaries that are not Wholly Owned Domestic Subsidiaries, and will also not include many of our domestic buildings, structures and other facilities, since many of those buildings, structures and facilities do not meet the minimum book value threshold specified in the definition.

“SEC” means the Securities and Exchange Commission or any successor agency.

“Significant Subsidiary” means any Subsidiary which is a “significant subsidiary” within the meaning of Rule 405 under the Securities Act.

Section 10-851 of the Arizona Revised Statutes (“ARS”) authorizes a corporation to indemnify a director made a party to a proceeding in such capacity, provided that (1) the individual’s conduct was in good faith; and (2) the individual reasonably believed that (a) in the case of conduct in an official capacity with the corporation, the conduct was in the best interests of the corporation; and (b) in all other cases, the conduct was at least not opposed to the corporation’s best interests; and (3) in the case of any criminal proceedings, the individual had no reasonable cause to believe the conduct was unlawful. Indemnification permitted in connection with a proceeding by or in the right of the corporation is limited to reasonable expenses incurred in connection with the proceeding. Additionally, a corporation may not indemnify a director in connection with a proceeding by or in the right of the corporation in which the director was adjudged liable to the corporation or in connection with any other proceeding charging improper financial benefit to the director in which the director was adjudged liable on the basis that financial benefit was improperly received by the director.

Unless otherwise limited by its articles of incorporation, Section 10-854 of the ARS requires a corporation to indemnify (a) an outside director whose conduct was in good faith and, in the case of conduct in an official capacity with the corporation, who reasonably believed that the conduct was in the best interests of the corporation and, in all other cases, who reasonably believed that the conduct was at least not opposed to its best interests, and, in the case of any criminal proceedings, the director had no reasonable cause to believe the conduct was unlawful and (b) a director who was the prevailing party, on the merits or otherwise, in the defense of any proceeding to which the director was a party because the director is or was a director of the corporation, against reasonable expenses incurred by the director in connection with the proceeding.

Section 607.0850(1) of the Florida Business Corporation Act (“FBCA”) empowers a corporation to indemnify any person who was or is a party to any proceeding (other than an action by, or in the right of, the corporation), by reason of the fact that he or she is or was a director, officer, employee, or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against liability incurred in connection with such proceeding, including any appeal thereof, if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any proceeding by judgment, order, settlement or conviction or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in, or not opposed to, the best interests of the corporation or, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

Section 607.0850(2) of the FBCA empowers a corporation to indemnify any person, who was or is a party to any proceeding by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses and amounts paid in settlement not exceeding, in the judgment of the board of directors, the estimated expense of litigating the proceeding to conclusion, actually and reasonably incurred in connection with the defense or settlement of such proceeding, including any appeal thereof. Such indemnification shall be authorized if such person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification shall be made under this subsection in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable unless, and only to the extent that, the court in which such proceeding was brought, or any other court of competent jurisdiction, shall determine upon application that, despite the adjudication of liability but in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

The Articles of Incorporation of L-3 Communications EO/IR, Inc. provide that the corporation shall indemnify its directors and officers to the full extent possible under the laws of the State of Florida.

Under Section 2-418 of the Maryland General Corporation Law (“MDGCL”), a Maryland corporation may indemnify any director who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that he is a present or former director of the corporation and any person who, while a director of the corporation, is

or was serving at the request of the corporation as a director, officer, partner, trustee, employee or agent of another corporation, partnership, joint venture, trust, limited liability company, other enterprise or employee benefit plan. Such indemnification may be against judgments, penalties, fines, settlements and reasonable expenses actually incurred by him in connection with the proceeding unless it is established that (a) the act or omission of the director was material to the matter giving rise to the proceeding and (i) was committed in bad faith; or (ii) was the result of active and deliberate dishonesty; or (b) the director actually received an improper personal benefit in money, property or services; or (c) in the case of any criminal proceeding, the director had reasonable cause to believe his act or omission was unlawful. However, the corporation may not indemnify any director in connection with a proceeding by or in the right of the corporation if the director has been adjudged to be liable to the corporation. A director who has been successful in the defense of any proceeding described above shall be indemnified against reasonable expenses incurred in connection with the proceeding. The corporation may not indemnify a director in respect of any proceeding charging improper personal benefit to the director in which the director was adjudged to be liable on the basis that personal benefit was improperly received. The corporation may not indemnify a director or advance expenses for a proceeding brought by the director against the corporation except if the proceeding is brought to enforce indemnification by the corporation or if the corporation’s charter or bylaws, a board resolution or an agreement approved by the board of directors of the corporation provides otherwise. Notwithstanding the above provisions, a court of appropriate jurisdiction, upon application of the director, may order indemnification if it determines that in view of all the relevant circumstances, the director is fairly and reasonably entitled to indemnification; however, indemnification with respect to any proceeding by or in the right of the corporation or in which liability was adjudged on the basis that personal benefit was improperly received shall be limited to expenses. A corporation may advance reasonable expenses to a director under certain circumstances, including a written undertaking by or on behalf of such director to repay the amount if it shall ultimately be determined that the standard of conduct necessary for indemnification by the corporation has not been met.

A corporation may indemnify and advance expenses to an officer of the corporation to the same extent that it may indemnify directors under Section 2-418 of the MDGCL.

The indemnification and advancement of expenses provided by the MDGCL are not exclusive of any other rights, by indemnification or otherwise, to which a director or officer may be entitled under the charter, bylaws, a resolution of shareholders or directors, an agreement or otherwise.

Section 14A:3-5 of the New Jersey Business Corporation Act (“NJBCA”) empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he is or was a corporate agent (i.e., a director, officer, employee or agent of the corporation or a director, officer, trustee, employee or agent of another corporation or enterprise serving as such at the request of the indemnifying corporation), against reasonable costs (including attorneys’ fees), judgments, fines, penalties and amounts paid in settlement incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal proceeding,

had no reasonable cause to believe that such conduct was unlawful. Section 14A:3-5 of the NJBCA also empowers a corporation to indemnify a corporate agent against reasonable costs (including attorneys’ fees) incurred by him in connection with any proceeding by or in the right of the corporation to procure a judgment in its favor which involves such corporate agent by reason of the fact that he is or was a corporate agent if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Superior Court of New Jersey or the court in which such action or suit was brought shall determine that despite the adjudication of liability, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

To the extent that a corporate agent has been successful in the defense of any action, suit or proceeding referred to above, or in the defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) incurred by him in connection therewith. Section 14A:3-5 further provides that indemnification provided for by Section 14A:3-5 shall not be deemed exclusive of any rights to which the indemnified party may be entitled. The NJBCA also empowers a corporation to purchase and maintain insurance on behalf of any corporate agent against any liability asserted against him or expenses incurred by him by reason of his being or having been a corporate agent whether or not the corporation would have the power to indemnify him against such liabilities and expenses under NJBCA Section 14A:3-5.

Section 78.7502 of the Nevada Revised Statutes (“NRS”) allow a company to indemnify its officers, directors, employees and agents from any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, except an action by or in the right of the corporation. Indemnification may only occur if a determination has been made that the officer, director, employee or agent acted in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful. Unless ordered by a court or expenses are advanced pursuant to Section 78.751(2) of the NRS, a determination of discretionary indemnification may be made by the shareholders; the board of directors by majority vote of a quorum consisting of directors who were not parties to the action, suit, or proceeding; by opinion of independent legal counsel if ordered by a majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding; or by opinion of independent legal counsel in the event a quorum of directors who were not a party to such action, suit, or proceeding does not exist.

Section 1701.13(E) of the Ohio Revised Code (“ORC”) gives a corporation incorporated under the laws of Ohio authority to indemnify or agree to indemnify its directors and officers against certain liabilities they may incur in such capacities in connection with any threatened, pending, or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action brought by or in the right of the corporation, provided that the director or officer acted in good faith and in a manner that the person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, the person had no reasonable cause to believe his or her conduct was unlawful. In the case of an action or suit by or in the right

of the corporation, the corporation may indemnify or agree to indemnify its directors and officers against certain liabilities they may incur in such capacities, provided that the director or officer acted in good faith and in a manner that the person reasonably believed to be in or not opposed to the best interests of the corporation, except that an indemnification shall not be made in respect of (a) any claim, issue or matter as to which the person is adjudged to be liable for negligence or misconduct in the performance of his or her duty to the corporation unless and only to the extent that the court of common pleas or the court in which the action or suit was brought determines, upon application, that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnification for expenses that the court considers proper or (b) any action or suit in which the only liability asserted against a director is pursuant to Section 1701.95 of the ORC relating to unlawful loans, dividends and distribution of assets.

Section 8.101 of the Texas Business Organizations Code (“TXBOC”) authorizes a Texas corporation to indemnify a governing person, former governing person or delegate who was, is, or is threatened to be made a respondent in a proceeding, including any threatened, pending or completed action or other proceeding, whether civil, criminal, administrative, arbitrative or investigative. The TXBOC provides that indemnification is permitted only if it is determined in accordance with the TXBOC that the person (1) acted in good faith; (2) reasonably believed (a) in the case of conduct in the person’s official capacity, that the person’s conduct was in the corporation’s best interests; and (b) in any other case, that the person’s conduct was not opposed to the corporation’s best interests; and (3) in the case of any criminal proceeding, did not have a reasonable cause to believe the person’s conduct was unlawful. A governing person, former governing person or delegate may be indemnified under Section 8.101 of the TXBOC against judgments and expenses that are reasonably and actually incurred by the person (including court costs and reasonable attorneys’ fees), but if the person is found liable to the corporation or is found liable on the basis that the person improperly received a personal benefit, the indemnification is limited to reasonable expenses actually incurred and shall not be made in respect of any proceeding in which the person has been found liable for willful or intentional misconduct in the performance of the person’s duty to the corporation. A corporation is obligated under Section 8.051 of the TXBOC to indemnify a governing person, former governing person or delegate against reasonable expenses actually incurred by the person in connection with a proceeding in which the person is a respondent because the person is or was a governing person or delegate if the person is wholly successful, on the merits or otherwise, in the defense of the proceeding. A corporation is obligated to indemnify an officer to the same extent required under the TXBOC for a governing person. Under Sections 8.105 and 8.151 of the TXBOC a corporation may (1) indemnify and advance expenses to a person who is not a governing person, including an officer, employee or agent, to the extent consistent with other law, as may be provided by the corporation’s articles of incorporation, bylaws, action of its board of directors, contract or common law and (2) purchase and maintain insurance or another arrangement on behalf of an existing or former governing person, delegate or such other person identified in (1) above against any liability asserted against and incurred by the person in that capacity or arising out of the person’s status in that capacity.

The Articles of Incorporation and the Bylaws of L-3 Unmanned Systems, Inc. provide that the corporation shall indemnify its directors and officers to the full extent possible under the laws of the State of Texas.

The Articles of Incorporation of L-3 Unmanned Systems, Inc. provide that the liability of directors of the corporation for monetary damages shall be eliminated to the fullest extent permissible under the laws of the State of Texas.

Section 13.1-697 of the Virginia Stock Corporation Act (“VASCA”) empowers a corporation to indemnify an individual made a party to a proceeding because he is or was a director against liability incurred in the proceeding if: (1) he conducted himself in good faith; and (2) he reasonably believed (i) in the case of conduct in his official capacity with the corporation, that his conduct was in its best interests; and (ii) in all other cases, that his conduct was at least not opposed to its best interests; and (3) in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful. A corporation may not indemnify a director (1) in connection with a proceeding by or in the right of the corporation except for reasonable expenses incurred in connection with the proceeding if it is determined that the director has met the relevant standard in the preceding sentence; or (2) in connection with any other proceeding charging improper personal benefit to the director, whether or not involving action in his official capacity, in which he was adjudged liable on the basis that personal benefit was improperly received by him. Unless limited by its articles of incorporation, a corporation must indemnify a director who entirely prevails in the defense of any proceeding to which he was a party because he is or was a director of the corporation against reasonable expenses incurred by him in connection with the proceeding. Under the VASCA, a corporation may pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding in advance of the final disposition of the proceeding if: (1) the director furnishes the corporation a signed written affirmation of his good faith belief that he has met the standard of conduct described in Section 13.1-697 of the VASCA; and (2) the director furnishes the corporation a signed written undertaking, executed personally or on his behalf, to repay the advance if the director is not entitled to mandatory indemnification under Section 13.1-698 of the VASCA and it is ultimately determined that he did not meet the relevant standard of conduct. Unless a corporation’s articles of incorporation provide otherwise, the corporation may indemnify and advance expenses to an officer of the corporation to the same extent as to a director. A corporation may also purchase and maintain on behalf of a director or officer insurance against liabilities incurred by him in that capacity or arising from his status as a director or officer, whether or not the corporation would have the power to indemnify him against the same liability under the VASCA.

The Articles of Incorporation of Titan Facilities, Inc. provide that the corporation shall indemnify its directors and officers to the full extent possible under the laws of the State of Virginia.

On behalf of itself and all of its subsidiary guarantors, the Company has directors’ and officers’ liability insurance policies, with coverage, in the aggregate, of up to $200 million, subject to various deductibles and exclusions from coverage.

(a)(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) shall not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of this registration statement as of the date the filed prospectus was deemed part of and included in this registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in this registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of this registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of this registration statement or made in a document incorporated or deemed

incorporated by reference into this registration statement or prospectus that is part of this registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in this registration statement or the prospectus that was part of this registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) That, for purposes of determining any liability under the Securities Act, each filing of such registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, as amended, each of the registrants certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of New York, State of New York, on the 8th day of May, 2013.
