AGREEMENT AND PLAN OF MERGER

This Agreement and Plan of Merger (this "Agreement") is made and entered into as of March 31, 2004, by and among SYS, a California corporation ("SYS"); Shadow Research International, Inc., a Delaware corporation and a wholly owned subsidiary of SYS ("Subcorp"); Polexis, Inc., a California corporation ("Polexis"); ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, an individual resident in the State of California, ▇▇▇▇ ▇▇▇▇▇, an individual resident in the State of California, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇, an individual resident in the State of California, and ▇▇▇▇ ▇▇▇▇▇, an individual resident in the State of California (collectively, the "Polexis Principal Common Stockholders"); Nextreme Ventures, LLC, a Delaware limited liability company, ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇, an individual resident in the State of California, Ellumina, LLC, a Delaware limited liability company, BridgeWest, LLC, a Delaware limited liability company, Gladehill Development Corp., a Nevada corporation, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, an individual resident in the State of California, and ▇▇▇▇ ▇▇▇▇▇▇▇, an individual resident in the State of California (collectively, the "Polexis Preferred Stockholders"). The Polexis Principal Common Stockholders and the Polexis Preferred Stockholders are sometimes referred to collectively herein as the "Polexis Principal Stockholders."

PRELIMINARY STATEMENTS

WHEREAS, the respective Boards of Directors of SYS, Subcorp and Polexis have determined that the merger of Subcorp with and into Polexis, in the manner contemplated herein (the "Merger"), is desirable and in the best interests of their respective stockholders and, by resolutions duly adopted, have approved and adopted this Agreement;

WHEREAS, SYS, Subcorp, Polexis and the Polexis Principal Stockholders desire to make certain representations, warranties, covenants and agreements in connection with the merger and also to prescribe various conditions to the merger.

NOW, THEREFORE, in consideration of these premises and their promises hereinafter set forth, the parties hereto agree as follows:

ARTICLE I
THE MERGER

1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the Delaware General Corporation Law (the "DGCL") and the California General Corporation Law (the "CGCL"), Subcorp shall be merged with and into Polexis at the Effective Time. As a result of the Merger, the separate corporate existence of Subcorp shall cease and Polexis shall continue its existence under the laws of the State of California as a wholly-owned subsidiary of SYS. Polexis, in its capacity as the corporation surviving the Merger, is hereinafter sometimes referred to as the "Surviving Corporation."

1.2 Effective Time. As promptly as possible on the Closing Date, the parties shall cause the Merger to be consummated by filing (a) with the Secretary of State of the State of Delaware (the "Delaware Secretary of State") a certificate of merger (the "Certificate of Merger") in such form as is required by and executed in accordance with the DGCL and (b) with the Secretary of State of the State of California (the "California Secretary of State") this Agreement and an officer's certificate from SYS and Polexis (collectively, the "California Merger Documents") in such form as is required by and executed in accordance with the CGCL. The Merger shall become effective (the "Effective Time") when the Certificate of Merger has been filed with the Delaware Secretary of State and when the California Merger Documents have been filed with the California Secretary of State or at such later time as shall be agreed upon by SYS and Polexis and specified in the Certificate of Merger and the California Merger Documents. Prior to the filings referred to in this Section 1.2, a closing (the "Closing") shall be held at the offices of SYS's counsel, ▇▇▇▇, Forward, ▇▇▇▇▇▇▇▇ & Scripps LLP ("▇▇▇▇ ▇▇▇▇▇▇▇"), ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, or such other place as the parties may agree on, as soon as practicable (but in any event within ten business days) following the date upon which all conditions set forth in Article VI that are capable of being satisfied prior to the Closing have been satisfied or waived, or at such other date as SYS and Polexis may agree;

provided that the conditions set forth in Article VI have been satisfied or waived at or prior to such date. The date on which the Closing takes place is referred to herein as the "Closing Date." For all purposes, the Closing shall be effective as of 11:59 p.m. on the Closing Date.

1.3 Effects of the Merger. At and after the Effective Time, the separate existence of Subcorp will cease, and Polexis as the Surviving Corporation and successor shall succeed to all the rights and property of Subcorp and Polexis, and shall be subject to all the debts and liabilities of Subcorp and Polexis except as otherwise expressly provided in reference to this Agreement.

1.4 Certificate of Incorporation and Bylaws. The (a) Amended and Restated Articles of Incorporation of Polexis, as in effect immediately prior to the Effective Time, shall be the Articles of Incorporation of the Surviving Corporation and (b) Bylaws of Polexis in effect immediately prior to the Effective Time shall be the Bylaws of the Surviving Corporation; in each case, until amended in accordance with the CGCL.

1.5 Directors and Officers of the Surviving Corporation. On the Closing Date, Polexis shall deliver to SYS evidence satisfactory to SYS of the resignations of the directors and officers of Polexis and any Subsidiary, with such resignations to be effective immediately after the Effective Time. SYS shall cause the election of new directors and officers, as determined by SYS, for Polexis and any Subsidiary to be effective as of the resignation of the former directors and officers of Polexis and any Subsidiary.

ARTICLE II
CONVERSION OF SECURITIES

2.1 Merger Consideration; Conversion of Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of SYS, Subcorp or Polexis or their respective stockholders, each share of Polexis Capital Stock issued and outstanding immediately prior to the Effective Time shall in accordance with Section 2.1(a) be converted into, and shall represent the right to receive, that portion of the aggregate amount of $5,236,000 (such aggregate amount, the "Merger Consideration"), as such share is entitled, with $2,586,000, payable in cash (the "Cash Consideration"), and $2,650,000, payable in the form of fifty-three (53) $50,000 SYS Units, with each Unit consisting of 12,690 shares of restricted SYS Common Stock (valued at $1.97 per share) and a $25,000 convertible promissory note ("Convertible Promissory Note") substantially in the form of Exhibit A hereto (such aggregate amount, the "Stock Consideration"). The Convertible Promissory Note shall be subject to a subordination agreement satisfactory in form and substance to SYS' principal lender, provided that such form of subordination agreement must also have received the reasonable approval of a majority of the Polexis Principal Common Stockholders.

(a) The Merger Consideration shall be allocated and distributed as set forth on Schedule 1, which has been determined in accordance with the following:

(i) Each issued share of Common Stock of Polexis shall, at the Effective Time, be converted into (i) $0.1145551 cash, (ii) 0.0542312 shares of common stock of SYS, and (iii) a Convertible Promissory Note with an original principal amount of $0.1068354.

(ii) Each issued share of Series A Preferred Stock of Polexis shall, at the Effective Time, be converted into (i) $0.7861153 cash; (ii) 0.1250559 shares of common stock of SYS; and (iii) a Convertible Promissory Note with an original principal amount of $0.2463609.

(iii) Each issued share of Series B Preferred Stock of Polexis shall, at the Effective Time, be converted into (i) $0.3218283 cash; (ii) 0.0511967 shares of common stock of SYS; and (iii) a Convertible Promissory Note with an original principal amount of $0.1008579.

(b) Deposit to Escrow. At the Closing, 330,203 shares of Common Stock (the "Escrow Stock Consideration") of the shares of Common Stock to be issued to the Polexis Principal Stockholders

as part of the Units which constitute the Stock Consideration shall be paid by SYS to the Escrow Agent, for deposit into the Escrow Account, as set forth in Section 2.5. The allocation of such shares among the Polexis Principal Stockholders shall be as set forth on Schedule 1.

(c) Deposit to Founders' Escrow. At the Closing, SYS shall deposit 25,381 shares of SYS Common Stock (the "Founders' Escrow Consideration") with the Escrow Agent on behalf of each of ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇ ▇▇▇▇▇ pursuant to the Founders' Escrow Agreements. Such 50,762 shares of Common Stock will be derived in equal amounts from the Units constituting part of the Stock Consideration otherwise payable to Mr. Glasgow and ▇▇. ▇▇▇▇▇.

(d) Direct Delivery. Notwithstanding Section 2.1(a), (i) the Escrow Stock Consideration shall not be delivered to the Polexis Principal Stockholders and shall instead be delivered to the Escrow Agent in accordance with Section 2.5(b), and (ii) the Founders' Escrow Consideration shall not be delivered in accordance with Section 2.1(a) and shall instead be deposited with the Escrow Agent pursuant to Section 2.1(c).

2.2 Conversion of Subcorp Stock. Each share of capital stock of Subcorp outstanding at the Effective Time shall be converted into and become one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

2.3 Fractional Shares; Adjustments.

(a) No certificates for fractional SYS Common Shares shall be issued as a result of the conversion provided for in Section 2.1, and such fractional share interests will not entitle the owner thereof to vote or have any rights of a holder of SYS Common Shares.

(b) In lieu of any such fractional SYS Common Shares, the holder of a certificate or certificates (the "Certificates") that immediately prior to the Effective Time represented outstanding shares of Polexis Capital Stock (each, a "Polexis Stockholder") whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.1(a), upon presentation of such fractional interest represented by an appropriate Certificate for Polexis Capital Stock to SYS pursuant to Section 2.4, shall be entitled to receive a cash payment therefore, in an amount equal to the value of such fractional interest, with an SYS Common Share being valued for this purpose as described in Section 2.1. Such payment with respect to fractional shares is intended to avoid the expense and inconvenience of issuing fractional shares and to provide a mechanical rounding off of, and is not a separately bargained for, consideration. If more than one Certificate shall be surrendered for the account of the same holder, the number of shares of Polexis Capital Stock for which Certificates have been surrendered shall be appropriately adjusted to provide to the Polexis Stockholders the same economic effect as contemplated by this Agreement. The fractional share interests of each Polexis Stockholder will be aggregated, and no Polexis Stockholder will receive cash in an amount greater than the value of one full SYS Common Share for such fractional share interest.

2.4 Exchange of Certificates.

(a) Exchange at Closing. At the Closing, each Polexis Principal Stockholder shall deliver (i) the Certificate or Certificates representing such Polexis Principal Stockholder's shares of Polexis Capital Stock (or affidavits of lost certificates in lieu thereof), duly endorsed in blank or accompanied by stock powers duly executed in blank and (ii) fully executed stock powers with respect to that Principal Stockholder's shares of SYS Common Stock which are to be deposited with the Escrow Agent, and in exchange for such delivery shall receive (i) the Cash Consideration (as determined pursuant to Section 2.1) to which such Polexis Principal Stockholder is entitled, payable by wire transfer of immediately available funds to the account specified by such Polexis Principal Stockholder, and (ii) the Stock Consideration (as determined pursuant to Section 2.1) to which such Polexis Principal Stockholder is entitled, payable by delivery of a Convertible

Promissory Note and a stock certificate naming such Polexis Principal Stockholder as the holder thereof.

(b) Exchange Procedures. As soon as practicable after the Effective Time, SYS shall mail to each holder of record of a Certificate (other than the Principal Polexis Stockholders), a letter of transmittal and instructions for effecting the surrender of the Certificate in exchange for the Merger Consideration to which such Polexis Stockholder is entitled, substantially in the form of Exhibit B (the "Letter of Transmittal") and an Investment Representation Certificate substantially in the form Exhibit C (the "Investment Representation Certificate"). Upon surrender of a Certificate for cancellation to SYS, together with a duly executed Letter of Transmittal and Investment Representation Certificate, the holder of such Certificate shall be entitled to receive in exchange therefor (i) the Stock Consideration which such holder has the right to receive pursuant to this Agreement in such denominations and registered in such names as such holder may request, and (ii) payment by check or wire transfer of funds in U.S. dollars representing (A) the amount of the Cash Consideration which such holder has the right to receive pursuant to the provisions of this Article II, and (B) the amount of cash in lieu of fractional shares, if any, and accrued and unpaid dividends, distributions, and interest on the Convertible Promissory Note, if any, which such holder has the right to receive pursuant to the provisions of this Article II, after giving effect to any required withholding tax. No interest will be paid or accrued on the cash in lieu of fractional shares, if any, and unpaid dividends and distributions, if any, payable to holders of shares of Polexis Capital Stock. In the event of a transfer of ownership of shares of Polexis Capital Stock that is not registered on the transfer records of Polexis, a certificate representing the proper number of SYS Common Shares, together with a convertible note in the appropriate amount and a check for the cash to be paid as part of the Cash Consideration and for the cash to be paid in lieu of fractional shares, if any, and unpaid dividends, distributions, and interest, if any, may be issued to such transferee if the Certificate representing such shares of Polexis Capital Stock held by such transferee is presented to SYS, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.4, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the appropriate amount of Merger Consideration upon surrender. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by SYS, the posting by such person of a bond in such reasonable amount as SYS may direct as indemnity against any claim that may be made against it with respect to such Certificate, SYS will deliver in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration, payable at Closing with respect to the shares of Polexis Capital Stock formerly represented thereby, and unpaid dividends and distributions on SYS Common Shares, if any, as provided in this Article II.

(c) Distributions with Respect to Unexchanged Shares. Notwithstanding any other provisions of this Agreement, no dividends or other distributions declared or made after the Effective Time with respect to SYS Common Shares having a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate, no cash payment as part of the Merger Consideration and no cash payment of interest or in lieu of fractional shares shall be paid to any such holder, until the holder shall surrender such Certificate (or affidavit) as provided in this Section 2.4. Subject to the effect of all applicable constitutions, laws, statutes, treaties, orders, rules, regulations, ordinances, notices, approvals, policies or guidelines promulgated, or judgments, decisions, decrees, or orders of any Governmental Authority (collectively, "Applicable Laws"), following surrender of any such Certificate, there shall be paid to the holder of the Merger Consideration issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole SYS Common Shares and not paid, less the amount of any

withholding taxes that may be required thereon, (ii) amount of cash representing accrued and unpaid interest on the Convertible Promissory Note constituting a portion of such Merger Consideration, and (iii) at the appropriate payment date subsequent to surrender, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole SYS Common Shares, less the amount of any withholding taxes which may be required thereon.

(d) No Further Ownership Rights in Polexis Capital Stock. All Merger Consideration issued and/or paid upon surrender of Certificates in accordance with the terms hereof (including any cash paid pursuant to this Article II) shall be deemed to have been issued and/or paid in full satisfaction of all rights pertaining to such shares of Polexis Capital Stock represented thereby, and, as of the Closing, the stock transfer books of Polexis shall be closed and there shall be no further registration of transfers on the stock transfer books of Polexis of shares of Polexis Capital Stock outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Section 2.4.

(e) No Liability. Neither SYS nor the Surviving Corporation shall be liable to any person in respect of any Merger Consideration (on dividends, distributions, or interest with respect thereto) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificates shall not have been surrendered prior to seven years after the Effective Time or immediately prior to such earlier date on which any Merger Consideration (or any dividends, distributions, or interest with respect thereto) would otherwise escheat to or become the property of any Governmental Authority, any such Merger Consideration (or dividends, distributions, or interest with respect thereto) shall, to the extent permitted by Applicable Law, become the property of SYS, free and clear of all claims or interest of any person previously entitled thereto. For purposes of this Agreement, "Governmental Authority" means any (A) nation, region, state, county, city, town, village, district or other jurisdiction, (B) federal, state, local, municipal, foreign or other government, (C) federal, state, local municipal, foreign or multi-national court, arbitral tribunal, administrative agency or commission, (D) other governmental, quasi-governmental, public, or regulatory body, agency, instrumentality or authority of any nature, (E) multi-national organization, (F) body exercising, or entitled to exercise, any administrative, executive, judicial, legislative, policy, regulatory or taxing authority or power of any nature or (G) official of any of the foregoing.

(f) Withholding Rights. Each of the Surviving Corporation and SYS shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any holder of shares of Polexis Capital Stock, such amounts as it is required to deduct and withhold with respect to the making of such payment under the United States Internal Revenue Code of 1986, as amended (the "Code") or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by the Surviving Corporation or SYS, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Polexis Capital Stock in respect of which such deduction and withholding was made by the Surviving Corporation or SYS, as the case may be. Any Tax withheld by SYS or the Surviving Corporation shall be paid by SYS or the Surviving Corporation, as the case may be, to the appropriate Governmental Authority when due in accordance with Applicable Law; and SYS or the Surviving Corporation, as the case may be, shall within 30 days of the payment of such Tax deliver to the holder of the shares of Polexis Capital Stock evidence reasonably satisfactory to such holder that payment was duly remitted to the appropriate Governmental Authority.

(g) Restrictive Legend. Each certificate evidencing SYS Common Shares issued pursuant to this Agreement shall bear the following legend in conspicuous type:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR REGISTERED OR QUALIFIED UNDER ANY STATE SECURITIES LAWS. THE SHARES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR QUALIFICATION WITHOUT AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION OR QUALIFICATION IS NOT REQUIRED.

2.5 Escrow Accounts.

(a) Escrow Agreement. On or prior to the Closing Date, SYS and Polexis shall establish an escrow at Union Bank of California, N.A. (the "Escrow Account"), by the execution and delivery of an Escrow Agreement substantially in the form attached as Exhibit D hereto (the "Escrow Agreement").

(b) Deposit of Merger Consideration. On the Closing Date, SYS shall pay to the Escrow Agent, for immediate deposit into the Escrow Account, the Escrow Stock Consideration, by delivery of one or more certificates, duly endorsed in blank by the Polexis Principal Stockholders, representing that number of SYS Common Shares comprising of the Escrow Stock Consideration, together with the related stock powers delivered to SYS pursuant to Section 2.4(b).

(c) Disbursement of Merger Consideration. All of the Escrow Stock Consideration deposited in the Escrow Account shall be available, in accordance with this Agreement and the Escrow Agreement, to secure, and to provide the sole and exclusive recourse for, the performance of the Polexis Principal Stockholders' indemnity obligations under Section 8.2 hereof, and to provide the sole and exclusive recourse for, the performance of the obligations of the Polexis Principal Stockholders under Section 5.3(f) hereof, and shall be paid to the Polexis Principal Stockholders only in accordance with (and with any amounts set forth on Schedule 1 subject to adjustment in accordance with) the terms and subject to the conditions set forth in the Escrow Agreement.

(d) Founders' Escrow Agreement. On or prior to the Closing Date, SYS and each of ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇ ▇▇▇▇▇ shall establish an escrow at Union Bank of California, N.A. (each a "Founders' Escrow Account"), by the execution and delivery of an Escrow Agreement substantially in the form attached as Exhibit E-1 and E-2 hereto (each a "Founders' Escrow Agreement").

(e) Deposit of the Founders' Escrow Consideration. On the Closing Date, SYS shall pay to the Escrow Agent, on behalf of Mr. Glasgow and ▇▇. ▇▇▇▇▇, for immediate deposit in the applicable Founders' Escrow Account, the Founders' Escrow Consideration by delivery of two or more certificates, duly endorsed in blank, representing that number of SYS Common Shares comprising the Founders' Escrow Consideration.

2.6 Internal Revenue Code Election. At its option, following the Closing Date SYS may make an election under Section 338(g) of the Internal Revenue Code of 1986, as amended, with regard to the Merger.

ARTICLE III
REPRESENTATIONS AND WARRANTIES OF SYS AND SUBCORP

In order to induce Polexis and the Polexis Principal Stockholders to enter into this Agreement, SYS and Subcorp, jointly and severally, hereby represent and warrant to Polexis and the Polexis Principal Stockholders that the statements contained in this Article III are true, correct and complete, except as otherwise expressly set forth in this Article III as of the date hereof unless another date is expressly stated below.

Each of SYS, Subcorp and each other subsidiary of SYS is a corporation duly organized, validly existing and, where applicable, in good standing under the laws of its state of incorporation with corporate power and authority to own, lease, use and operate its properties and to conduct its business as and where now owned, leased, used, operated and conducted. Each of SYS, Subcorp and each other subsidiary of SYS is duly qualified to do business and in good standing in each jurisdiction in which the nature of the business conducted by it or the property it owns, leases or operates, requires it to so qualify, except where the failure to be so qualified or in good standing in such jurisdiction would not have a Material Adverse Effect on SYS and its subsidiaries taken as a whole. SYS is not in default in the performance, observance or fulfillment of any provision of the SYS Articles of Incorporation, as amended (the "SYS Articles"), or the SYS Amended and Restated Bylaws, as amended, as in effect on the date hereof (the "SYS Bylaws"), and Subcorp and each other subsidiary of SYS is not in default in the performance, observance or fulfillment of any provisions of its Certificate of Incorporation or Bylaws. SYS has heretofore furnished to Polexis complete and correct copies of the SYS Articles and the SYS Bylaws and the Certificate of Incorporation and Bylaws of Subcorp and each other subsidiary of SYS.

3.2 Corporate Power and Authority. Each of SYS and Subcorp has all requisite corporate power and authority to enter into and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated by this Agreement. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby by SYS and Subcorp have been duly authorized by all necessary corporate action on the part of each of SYS and Subcorp. This Agreement has been duly executed and delivered by each of SYS and Subcorp and constitutes the legal, valid and binding obligation of each of SYS and Subcorp enforceable against each of them in accordance with its terms, except to the extent that such enforceability may be subject to applicable bankruptcy, insolvency, reorganization, moratorium and similar laws affecting the enforcement of creditors' rights generally or by general equitable principles.

3.3 Conflicts; Consents and Approvals. Neither the execution and delivery of this Agreement by SYS or Subcorp nor the consummation of the transactions contemplated hereby or thereby will:

(a) conflict with, or result in a breach of any provision of, the SYS Articles or the SYS Bylaws, the Subcorp Certificate of Incorporation or Bylaws or the governing documents of any other subsidiary of SYS;

(b) materially violate, or conflict with, or result in a material breach of any provision of, or constitute a material default (or an event that, with the giving of notice, the passage of time or otherwise, would constitute a default) under, or entitle any party (with the giving of notice, the passage of time or otherwise) to terminate, accelerate, modify or call a material default under, or result in the creation of any material Encumbrance upon any of the properties or assets of SYS or any of its subsidiaries under, any of the terms, conditions or provisions of any material note, bond, mortgage, indenture, deed of trust, license, contract, undertaking, agreement, lease or other instrument or obligation to which SYS or any of its subsidiaries is a party (for purposes of this Agreement, "Encumbrance" means any charge, claim, mortgage, servitude, easement, right of way, equitable interest, lease or other possessory interest, conditional sale or other title retention arrangement, lien, pledge, security interest, preference, priority, right of first refusal or similar restriction);

(c) materially violate any (i) order, writ, injunction, decree, statute, ruling, assessment, or arbitration or award of any Governmental Authority or (ii) Applicable Laws relating to SYS or any of its subsidiaries or their respective properties or assets; or

(d) require any action or consent or approval of, or review by, or registration or filing by SYS or any of its affiliates with, any third party or any Governmental Authority, other than registrations

(B) use its best efforts to include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all of the SYS Common Shares held by such Eligible Stockholder or underlying any Convertible Promissory Note held by such Eligible Shareholder (the "Registrable Securities") specified in a written request or requests, made within ten (10) days after receipt of such written notice from SYS by any Eligible Stockholder but only to the extent that such inclusion does not diminish the number of securities included by a holder of SYS Common Shares who has demanded such registration.

(C) If the registration of which SYS gives notice is for a registered public offering involving an underwriting, SYS will so advise the Eligible Stockholders as part of the written notice given pursuant to subsection (i) above. In such event the right of any Eligible Stockholder to registration pursuant to subsection (i) above shall be conditioned upon such Eligible Stockholder's participation in such underwriting and the inclusion of such Eligible Stockholder's Registrable Securities in the underwriting to the extent provided herein. The Eligible Stockholders proposing to distribute their Registrable Securities through such underwriting shall (together with SYS and the other holders of SYS Common Shares distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by SYS (or by the holders of SYS Common Shares who have demanded such registration). Notwithstanding any other provision of this Section 5.2(c), if the managing underwriter determines that marketing factors require a limitation of the number of SYS Common Shares to be underwritten, the managing underwriter may limit the number of SYS Common Shares to be included in such registration. SYS will so advise the Eligible Stockholders and any other holder of SYS Common Shares distributing their SYS Common Shares through the underwriting pursuant to piggyback registration rights similar to this Section 5.2(c), and the number of SYS Common Shares to be registered and other securities that may be included in the registration and underwriting shall be allocated among all stockholders in proportion, as nearly as practicable, to the respective amounts of registrable securities held by such stockholders and other securities held by other holders at the time of filing the registration statement. If any Eligible Stockholder disapproves of the terms of any such underwriting, he or she may elect to withdraw therefrom by written notice to SYS and the managing underwriter. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from registration, and shall not be transferred in a public distribution prior to ninety (90) days after the effective date of the registration statement relating thereto.

(iii) SYS shall provide to each Eligible Stockholder whose Registrable Securities are registered a suitable number of prospectuses, and supplements thereto, as soon as possible following the effectiveness of the registration or the filing of the supplement, as the case may be.

(iv) SYS shall have the right to terminate or withdraw any registration initiated by it under this Section 5.2(c) prior to the effectiveness of such registration whether or not any Eligible Stockholder has elected to include such Eligible Stockholders' Registrable Securities in such registration, but without prejudice to its obligation pursuant to this Section 5.2(c).

(v) SYS shall bear the expenses associated with the registration of Registrable Securities pursuant to this Section 5.2(c) exclusive of underwriters' and brokers' discounts and commissions and expenses of the Eligible Stockholders' legal counsel.

(d) Waiver of Conflict. Each of SYS, Subcorp and (effective after the Closing) Polexis hereby agrees that ▇▇▇▇▇▇ ▇▇▇▇▇▇ may represent any or all of the Polexis Stockholders in any matters arising after the Closing, whether or not relating to the Merger or the other transactions contemplated by this Agreement, and hereby waives any conflict of interest that may arise in connection with such representation.

(e) Insurance. Each of SYS and (effective after the Closing) Polexis hereby agrees to maintain insurance with respect to Polexis and its directors and officers until at least the second anniversary of the Closing, with such insurance to be at least equal in amount and in scope to the policies listed in Section 4.24 of the Polexis Disclosure Schedule and, to the extent such policies provide coverage post-Closing for occurrences pre-Closing, including without limitation director and officer liability coverage, to maintain such policies in place through at least the second anniversary of the Closing.

(f) Pre Closing Loan. On the Closing Date, but prior to the Closing, SYS shall lend Polexis $550,000 pursuant to a demand promissory note. Polexis shall use the proceeds of the loan as follows: $200,000 for employee bonuses (to be designated, or redesignated, in the event conditions fail, by the then directors and officers of Polexis), $300,000 in payment of a cash fee owed to ▇▇▇▇▇▇▇▇▇▇ and Co., and up to $50,000 to pay expenses of Polexis related to the Merger (following which payment no transaction related expenses shall remain unpaid).

(g) In addition, immediately upon the Closing, SYS shall issue two Units to ▇▇▇▇▇▇▇▇▇▇ and Co.

announced or received by it during such period pursuant to the requirements of Applicable Laws (other than documents which such party is not permitted to disclose under Applicable Laws), and (b) consistent with its legal obligations, all other information concerning it and its business, properties and personnel as SYS may reasonably request; provided, however, that Polexis may restrict the foregoing access to the extent that it reasonably concludes, after consultation with outside legal counsel, that (i) any Applicable Law requires Polexis to restrict access to any properties or information, (ii) providing such access would result in the loss of the attorney-client privilege, (iii) such documents discuss the pricing or dollar value of the transactions contemplated by this Agreement, (iv) such documents contain competitively sensitive information, the sharing of which could constitute a violation of any applicable Antitrust Laws or (v) such disclosure is reasonably likely to result in a breach of or default under any contract or agreement to which Polexis is a party.

All requests for access and information shall be coordinated through senior executives of the parties to be designated.

(d) No Solicitation. Until the consummation of the Merger or the termination of this Agreement:

(ii) Polexis will not, and will not permit or cause any Subsidiary or any of the officers or directors of it or any Subsidiary to, and shall direct its and such Subsidiary's employees, agents and representatives not to, directly or indirectly, engage in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any person relating to an Acquisition Proposal, whether such Acquisition Proposal arises or has arisen before or after the date of this Agreement, or otherwise facilitate any effort or attempt to make or implement an Acquisition Proposal.

(iii) Polexis will immediately cease all existing activities, discussions and negotiations with any parties conducted heretofore with respect to any Acquisition Proposal and request the return of all confidential information regarding such party provided to any such parties prior to the date hereof pursuant to the terms of any confidentiality agreements or otherwise.

(f) Certain Post-Closing Obligations. The Polexis Principal Stockholders shall pay $150,500 under the termination agreement with regard to Polexis' lease of its facility at 28▇▇ ▇▇▇▇▇▇ ▇▇▇ ▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇.

8.2 Indemnification.

(a) The Polexis Principal Stockholders (the "Polexis Indemnifying Parties"), shall jointly and severally indemnify and hold SYS, Subcorp and the Surviving Corporation (collectively, the "SYS Indemnified Parties") harmless from and against any and all liability, loss, cost and expense whatsoever, including reasonable fees of legal counsel and related disbursements (collectively, "Damages;" provided that the $150,500 to be paid from escrow for the facilities lease termination shall not be "Damages"), incurred by the SYS Indemnified Parties as a result of or related to any breach of any representation, warranty, covenant or agreement made as of the Closing Date by Polexis in Article IV or Article V of this Agreement or in any certificate or schedule delivered pursuant thereto, subject to the following:

(i) Subject to Section 8.2(d), the SYS Indemnified Parties' sole and exclusive recourse for Damages shall be from the Escrow Stock Consideration, and no deficiency actions shall be permitted.

(ii) The per share value of any portion of the Escrow Stock Consideration released to SYS from the Escrow Account in order to pay a claim for Damages or otherwise shall be equal to the average closing price of SYS Common Stock as reported on the principal exchange on which it is then traded during the ten (10) trading days immediately preceding the release date.

(iii) No Damages shall be required to be paid by the Polexis Indemnifying Parties pursuant to this Section 8.2 until and unless the aggregate amount of Damages exceeds $100,000, but if such aggregate amount of Damages exceeds $100,000 then the full amount of such Damages up to all of the proceeds of the Escrow Account shall be required to be paid by the Polexis Indemnifying Parties.

(b) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the SYS Indemnified Parties by a third party with respect to which indemnity may be sought pursuant to this Article VIII, the following procedures shall apply:

(i) The SYS Indemnified Parties shall promptly give written notice thereof to the Polexis Indemnifying Parties. The notice shall state the information then available regarding the amount of the claim and shall specify the provision or provisions of this Agreement under which the right to indemnification is being asserted.

(ii) If within thirty days after receiving such notice, the Polexis Indemnifying Parties give written notice to the SYS Indemnified Parties stating they intend to defend against such claim at their own cost and expense, the defense (including the right to settle or compromise such action) of such matter, including selection of counsel (subject to the consent of the SYS Indemnified Parties, which consent shall not be unreasonably withheld) and the sole power to direct and control such defense, shall be by the Polexis Indemnifying Parties, and the SYS Indemnified Parties shall make no payment in respect of such claim to any third party as long as the Polexis Indemnifying Parties are conducting a good faith and diligent defense. In any such defense, the Polexis Indemnifying Parties will consult with the SYS Indemnified Parties (who shall provide all reasonable cooperation) in connection with the Polexis Indemnifying Parties' defense.

(iii) In any such proceeding, each of the SYS Indemnified Parties shall have the right to retain its own counsel, at its own cost and expense unless: (A) the Polexis Indemnifying Parties and the SYS Indemnified Parties shall have mutually agreed to the contrary; (B) the Polexis Indemnifying Parties have failed within a reasonable time to retain counsel, in which event the SYS Indemnified Parties shall have the right to retain counsel, the cost of which shall constitute Damages; or (C) the named parties in any such proceeding (including any impleaded parties) include both the SYS Indemnified Parties and the Polexis Indemnifying Parties and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the Polexis Indemnifying Parties shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be responsible in Damages for fees and expenses of more than one separate firm (in addition to any local counsel) for the SYS Indemnified Parties, and that all such fees and expenses shall be reimbursed as they are incurred.

(iv) The Polexis Indemnifying Parties shall not be responsible in Damages for any settlement of any proceeding effected without their consent. Notwithstanding the foregoing, if at any time the SYS Indemnified Parties shall have requested the Polexis Indemnifying Parties to reimburse the SYS Indemnified Parties for fees and expenses of counsel as contemplated herein, the Polexis Indemnifying Parties agree that they shall be responsible in Damages for any settlement of any proceeding effected without their written consent herein if (x) such settlement is entered into more than 30 days after receipt by the Polexis Indemnifying Parties of the aforesaid request; and (y) the Polexis Indemnifying Parties shall not have reimbursed the SYS Indemnified Parties in accordance with such request (other than due to a reasonable dispute as to the validity of such request) prior to the date of settlement. If no such notice of intent to dispute and defend is given by the Polexis Indemnifying Parties, or if such diligent

good faith defense is not being or ceases to be conducted, the SYS Indemnified Parties shall, at the expense in Damages of the Polexis Indemnifying Parties, undertake the defense of such claim or Damages with counsel selected by the SYS Indemnified Parties, and shall have the right to compromise or settle the same exercising reasonable business judgment. The SYS Indemnified Parties shall make available all information and assistance that the Polexis Indemnifying Parties may reasonably request and shall cooperate with the Polexis Indemnifying Parties in such defense.

(v) Notwithstanding anything herein to the contrary, the Polexis Indemnifying Parties shall have the right to settle all claims of third parties for which indemnification is payable hereunder without the consent of the SYS Indemnified Parties so long as such settlement releases the SYS Indemnified Parties from all liability for or in connection with such action and does not include equitable relief against any of the SYS Indemnified Parties.

(c) Notwithstanding anything herein to the contrary, no claim by the SYS Indemnified Parties against the Polexis Indemnifying Parties may be made unless written notice of such breach is given in accordance with this Article VIII prior to the Cut-Off Date.

(d) Except in the case of fraud and for any nonmonetary, equitable relief to which any SYS Indemnified Party may be entitled, the rights and remedies set forth in Section 8.2 shall constitute the sole and exclusive rights and remedies of the parties hereto under or with respect to the subject matter of this Agreement.

8.3 Insurance Recoveries. The SYS Indemnified Parties will use their commercially reasonable efforts to first recover, under any insurance policy maintained by the SYS Indemnified Parties, any Damages covered by such insurance before seeking indemnification under Section 8.2. If, notwithstanding such efforts, the Polexis Indemnifying Parties are obligated to provide indemnification under Section 8.2 for Damages covered by the insurance in question then, to the extent permissible under Applicable Law and the applicable insurance policy, the SYS Indemnified Parties shall assign to the Polexis Indemnifying Parties all of its contractual and tort rights against the insurer in connection with the insurer's failure to perform under such insurance, and shall cooperate with the Polexis Indemnifying Parties, as reasonably requested, in the prosecution of such rights.

Agreement. If for any reason, any provision is determined to be invalid or in conflict with any existing, or future law or regulation by a court or agency having valid jurisdiction, such will not impair the operation or have any other effect upon such other provisions of this Agreement as may remain otherwise valid, and the latter will continue to be given full force and effect and bind the parties hereto.

9.12 Letter of Intent. SYS and Polexis acknowledge and agree that the execution and delivery of this Agreement by the parties hereto terminates the Letter of Intent and that their respective obligations thereunder are hereby null and void.

EXHIBIT A

Convertible Promissory Note

EXHIBIT A

THIS NOTE AND THE SHARES ISSUABLE UPON CONVERSION OF THIS NOTE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THIS NOTE AND THE SHARES ISSUABLE UPON CONVERSION OF THIS NOTE MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THIS NOTE UNDER SAID ACT OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO SYS THAT SUCH REGISTRATION IS NOT REQUIRED.

CONVERTIBLE NOTE

FOR VALUE RECEIVED, SYS, a California corporation (the "Borrower"), hereby promises to pay to (the "Holder"), the sum of Twenty-Five Thousand Dollars ($25,000), with simple interest accruing at the annual rate of ten percent (10%), on , 2007 (the "Maturity Date").

The following terms apply to this Note:

ARTICLE 1
PAYMENT RELATED PROVISIONS

1.1 Payment Grace Period. The Borrower will have a twenty (20) day grace period to pay any monetary amounts due under this Note, after which grace period a default interest rate of the higher of (i) one percent (1%) per month or (ii) the maximum amount allowed by law will apply to the amounts past due hereunder.

1.2 Interest Rate. Subject to the Holder's right to convert, interest payable on this Note will accrue at the annual rate of ten percent (10%) and be payable (i) on each April 1, July 1, October 1 and January 1, commencing July 1, 2004 (ii) on any Conversion Date and (iii) on the Maturity Date, accelerated or otherwise, when the principal and remaining accrued but unpaid interest is due and payable.

ARTICLE 2
CONVERSION RIGHTS

The Holder will have the right to convert the principal amount due under this Note into Shares of the Borrower's Common Stock as set forth below.

2.1 Conversion Rights. The Holder will have the right from and after the Closing Date, and then at any time until the Maturity Date, to convert all, but not part, of the outstanding and unpaid principal portion of this Note (the date of giving of such notice of conversion, a "Conversion Date") into shares of fully paid and nonassessable shares of restricted common stock of the Borrower (as such stock exists on the date of issuance of this Note, or any shares of capital stock of the Borrower into which such stock is hereafter changed or reclassified, the "Common Stock") at an initial per share conversion price equal to $2.32 per share (the "Conversion Price"). Within five (5) business days after the delivery to the Borrower of the attached Notice of Conversion, fully executed by the Holder, the Borrower will issue and deliver to the Holder the shares of Common Stock issuable in the conversion, along with accrued but unpaid interest on the Note through the Conversion Date. In the event that at any time and from time to time following the six-month anniversary of the date of this Note but ending on October 15, 2005 (i) the resale of the shares of Common Stock underlying this Note is subject to an effective registration statement under the Securities Act of 1933, as amended, and (ii) the closing price of the Borrower's Common Stock on the principal exchange on which it is traded is $3.00 or more for five or more consecutive trading days, then, at any time within twenty (20) days thereafter, Borrower

A-1

may demand the conversion of up to a total of 50% of the original principal amount of this Note and, upon such demand, 50% of the principal amount of this Note shall be converted in accordance with the terms hereof. Certificates evidencing shares of Common Stock issued upon conversion of this Note shall bear a legend indicating that the issuance of the shares was not registered under applicable securities laws and that the shares may be resold only pursuant to a registration or an exemption from registration.

2.2 Conversion Price Adjustments. The Conversion Price described in Section 2.1 and the number and kind of shares or other securities to be issued upon conversion determined pursuant to Section 2.1 is subject to adjustment upon any of the following events:

2.3 Merger, Consolidation or Sale of Assets. If the Borrower at any time consolidates with or merges into, or sells or conveys all or substantially all of its assets to, any other entity, the unpaid principal portion of this Note and accrued interest thereon will thereafter be deemed to evidence the right to purchase such number and kind of shares or other securities and property as would have been issuable or distributable, on account of such consolidation, merger, sale or conveyance, upon or with respect to the securities subject to the conversion or purchase right immediately prior to such consolidation, merger, sale or conveyance. The foregoing provision will similarly apply to successive transactions of a similar nature by any such successor or purchaser. Without limiting the generality of the foregoing, the anti-dilution provisions of this Section 2.2.3 and 2.2.4 will apply to such securities of such successor or purchaser after any such consolidation, merger, sale or conveyance.

2.4 Reclassification. If the Borrower at any time, by reclassification or otherwise, changes the Common Stock into the same or a different number of securities of any class or classes, the unpaid principal portion of this Note and accrued interest thereon will thereafter be deemed to evidence the right to purchase such number and kind of securities as would have been issuable as the result of such change with respect to the Common Stock immediately prior to such reclassification or other change.

2.5 Stock Splits, Combinations and Dividends. If the shares of Common Stock are subdivided or combined into a greater or smaller number of shares of Common Stock, or if a dividend is paid on the Common Stock in shares of Common Stock, the Conversion Price will be proportionately reduced in case of subdivision of shares or stock dividends or proportionately increased in the case of combination of shares, in each such case by the ratio which the total number of shares of Common Stock outstanding immediately after such event bears to the total number of shares outstanding immediately prior to such event.

2.6 Share Issuance. Subject to the provisions of this Section 2.2, if the Borrower at any time issues any shares of Common Stock prior to the conversion of the entire principal amount of the Note (other than (i) as provided in this Section 2.2 or (ii) (a) pursuant to options, warrants or other obligations to issue shares outstanding on the date hereof; (b) pursuant to options, warrants or other obligations to issue shares pursuant to a Company Plan or otherwise for employees, consultants and directors and (c) pursuant to any shares issued or to be issued in connection with other convertible notes, a merger or acquisition transaction) for a consideration less than the Conversion Price that would be in effect at the time of such issue, then, and thereafter successively upon each such issue, the Conversion Price will be reduced as follows: (x) the number of shares of Common Stock outstanding immediately prior to such issue will be multiplied by the Conversion Price in effect at the time of such issue and the product will be added to the aggregate consideration, if any, received by the Borrower upon such issue of additional shares of Common Stock and (y) the sum so obtained will be divided by the number of shares of Common Stock outstanding immediately after such issue. The resulting quotient will be the adjusted Conversion Price. Except for issuances pursuant to clauses (i) and (ii) of this Section 2.2.4, for purposes of this adjustment the issuance of any security of the Borrower carrying the right to convert such security into shares of Common Stock or of any warrant, right or option to

A-2

purchase Common Stock will result in an adjustment to the Conversion Price upon the issuance of shares of Common Stock pursuant to such conversion or purchase rights.

2.7 Reservation of Shares. As of the issuance date of this Note and for the remaining period during which the conversion right exists, the Borrower will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Common Stock upon the full conversion of this Note. The Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. The Borrower agrees that its issuance of this Note constitutes full authority to its officers, agents and transfer agents who are charged with the duty of executing and issuing stock certificates to execute and issue the necessary certificates for shares of Common Stock upon the conversion of this Note.

ARTICLE 3
EVENTS OF DEFAULT

The occurrence of any of the following events (each, an "Event of Default") will, at the option of the Holder, make all sums of principal and interest then remaining unpaid hereon and all other amounts payable hereunder immediately due and payable, all without demand, presentment or notice, or grace period, all of which hereby are expressly waived, except as set forth below:

3.1 Failure to Pay Principal or Interest. The Borrower fails to pay any installment of principal or interest hereon when due and such failure continues past the grace period allowed in Section 1.1 hereof.

3.2 Breach by Borrower. The Borrower breaches any material representation, warranty, covenant or other term or condition of this Note in any material respect and such breach, if subject to cure, continues for a period of twenty (20) days after written notice to the Borrower from the Holder.

3.3 Receiver or Trustee. The Borrower makes an assignment for the benefit of creditors, applies for or consents to the appointment of a receiver or trustee for the Borrower or for a substantial part of its property or business or such a receiver or trustee is otherwise appointed.

3.4 Bankruptcy. Bankruptcy, insolvency, reorganization or liquidation proceedings or other proceedings or relief under any bankruptcy law or similar law are instituted by or against the Borrower and are not dismissed within forty-five (45) days of initiation.

3.5 Default. The Borrower, after applicable notice and cure periods, defaults under any one or more of its obligations in an aggregate monetary amount in excess of $500,000 and such default is not remedied within 90 days.

3.6 Failure to Deliver Common Stock. The Borrower fails to timely deliver Common Stock to the Holder pursuant to and in the form required by this Note.

ARTICLE 4

In the event that the rate of interest required to be paid or other charges hereunder exceed the maximum permitted by such law, any payments in excess of such maximum will be credited against amounts owed by the Borrower to the Holder and thus refunded to the Borrower.

4.6 Arbitration.

INSTRUCTIONS

This Letter of Transmittal will instruct SYS on how you want SYS to exchange your Polexis Stock in connection with the Merger.

1. Execution and Delivery. All Polexis stock certificates must be accompanied by a completed and signed Letter of Transmittal. You may choose any method you like to deliver these documents to SYS; however, you assume all risks of non-delivery. Delivery shall be effected, and risk of loss and title to the certificates transmitted shall pass, only upon receipt of the certificates by SYS. Accordingly, it is recommended that you send your certificates by registered mail and have them properly insured.

2. Signatures. You must sign the form exactly the way your name appears on the face of the certificates. If the shares are owned by two or more persons, each must sign exactly as his or her name appears on the face of the certificate. If the shares of Polexis Stock described on the Letter of Transmittal have been assigned by the registered owner, the form should be signed in exactly the same way as the name of the last transferee indicated on the certificates or transfer documents.

If the form is signed by anyone who does not appear as the registered owner of the certificates listed, the certificates must be endorsed or accompanied by appropriate stock powers which are, in either case, signed by the registered owner as the name that appear on the certificates and that signature must be guaranteed by a member of the Medallion signature guarantee program.

If the form is signed by a trustee, executor, administrator, guardian, officer of a corporation, attorney-in-fact, or by any others acting in a representative or fiduciary capacity, the person signing, unless such person is the registered owner, must give such person's full title in such capacity and appropriate evidence of authority to act in such capacity must be forwarded to the Exchange Agent with the Letter of Transmittal.

3. Stock Certificates in Same Name. If you are requesting that SYS issue stock certificates and promissory notes in exactly the name that appears on the Polexis stock certificates, you do not need to endorse the certificates submitted with this Letter of Transmittal.

4. Stock Certificates in Different Name. If you are requesting that SYS issue stock certificates and promissory notes in a name other than exactly the name that appears on your Polexis certificates, you must endorse your Polexis certificates or send with them appropriately signed stock powers, and the signature on the form, as well as the signature on your certificates or on the stock powers, must be guaranteed by a member of the Medallion signature guarantee program.

5. Lost Certificates. If any of your Polexis certificates have been lost, stolen, or destroyed, you must submit an affidavit of lost certificate satisfactory to SYS, along with a bond of indemnity or other indemnity agreement acceptable to SYS. Prior to sending such documents, please notify SYS at the address shown on the first page of this Letter of Transmittal for further instructions.

6. Miscellaneous. A single SYS stock certificate and promissory note will be issued to you in exchange for all the shares of Polexis Stock covered by this Letter of Transmittal. SYS will not issue any fractional shares of SYS Stock in connection with the Merger. If you would otherwise be entitled to receive a fraction of an SYS share, you will instead receive a check in an amount equal to $ multiplied by such fraction. The check for cash in lieu of a fractional share will be issued and delivered in accordance with the special instructions specified on the form for the issuance and delivery of SYS stock certificates contained in the Letter of Transmittal.

7. Substitute Form W-9. You are required to provide SYS with a correct taxpayer identification number on the Substitute Form W-9 which is included as part of this Letter of Transmittal. If you fail to provide the information on the form, you will be subject to 28% Federal income tax withholding.

8. Questions and Requests for Information or Assistance. If you have any questions or need assistance relating to the Letter of Transmittal please contact SYS (telephone: - - ). You may obtain additional copies of the form from SYS at the address indicated on the first page of the Letter of Transmittal.

9. Distributions of SYS Shares; Dividends. SYS anticipates that a certificate for SYS Stock and promissory notes will be mailed to you approximately one week after receipt of your properly submitted Letter of Transmittal and your Polexis stock certificates and the closing of the Merger. Until you surrender your Polexis stock certificates with a properly completed Letter of Transmittal, SYS will not pay any dividends or other distributions otherwise payable to you on the SYS Stock or promissory note.

In no event will SYS or Polexis be liable to you for any SYS Stock or promissory note, any related dividends, or any cash delivered by them in good faith to a public official under any applicable abandoned property, escheat, or similar law. In no event will you be entitled to receive any interest on any cash to be distributed to you for fractional shares in connection with the Merger.

Simultaneous with the execution and delivery of this Escrow Agreement on the Closing Date, and pursuant to Section 2.1(b) of the Merger Agreement, SYS has deposited with the Escrow Agent, and the Escrow Agent hereby acknowledges receipt of 330,203 shares of SYS common stock (together with any cash proceeds of any liquidation of any such shares, the "Escrow Stock Amount" or the "Escrow Amount"), via physical delivery of certificates representing such shares, together with stock powers duly endorsed in blank by the Polexis Principal Stockholders. The Escrow Agent shall vote the Escrow Stock Amount in accordance with written instructions to be received from SYS.

(b) Subject to Section 5(d), on October 15, 2005 (or, if the Escrow Agent is closed on such date, the next day upon which the Escrow Agent is open for business), the remaining balance of the Escrow Amount.

D-1

5. Lease Termination Disbursement and Indemnity Claims. Upon notice from SYS, the Escrow Agent shall disburse to SYS a portion of the Escrow Amount to satisfy the obligations of the Polexis Principal Stockholders under Section 5.3(f) of the Merger Agreement. In the event that any Indemnified Party gives notice of a claim for indemnification to the Polexis Indemnifying Parties, pursuant to Section 8.2(c) of the Merger Agreement, on or prior to October 15, 2005 (a "Merger Agreement Notice"), then SYS shall deliver a Notice to each Polexis Principal Stockholder and to the Escrow Agent (a "Claim Notice"), containing a copy of such Merger Agreement Notice and specifying in reasonable detail the amount and nature of the Claim and requesting that the Escrow Agent make a disbursement to SYS in the amount specified therein.

(a) The Polexis Principal Stockholders shall have ten calendar days following receipt of a Claim Notice (the "Objection Period") to deliver a Notice to the Escrow Agent and SYS (an "Objection Notice") objecting to all or any portion of the amount specified in the Claim Notice.

(b) If the Escrow Agent does not receive a timely Objection Notice, then the Escrow Agent shall pay the amount of the disbursement set forth in the Claim Notice from the Stock Escrow Amount.

(c) If the Escrow Agent does receive a timely Objection Notice, SYS shall notify the Escrow Agent, within two business days following receipt of the Objection Notice, and the Escrow Agent shall (i) disburse to SYS, from the Stock Escrow Amount, a number of shares equal in value to the portion, if any, of the amount specified in the Claim Notice to which the Polexis Principal Stockholders do not object and (ii) segregate and hold, separate from the Stock Escrow Amount, a number of shares equal in value to the amount specified in the Claim Notice to which the Polexis Principal Stockholders object (the portion of the Escrow Amount to be so segregated, a "Disputed Amount").

(d) The Escrow Agent shall retain any Disputed Amount until the earlier of the receipt by the Escrow Agent of (i) a joint Notice from SYS and the Polexis Principal Stockholders indicating that the objection has been resolved and instructing the Escrow Agent to disburse or credit the Disputed Amount, or any applicable portion thereof, to SYS or the Polexis Principal Stockholders, respectively, or (ii) a true and correct copy of a final, non-appealable decision of a court or arbitrator relating to such Claim, which the Escrow Agent shall assume was obtained pursuant to the procedures set forth in Sections 8.2 and 9.7 of the Merger Agreement (an "Indemnity Claim Judgment"), ordering the Escrow Agent to disburse the Disputed Amount, at which time the Escrow Agent shall promptly disburse the Disputed Amount in accordance therewith.

(e) In the event of a disbursement to SYS, if the resale of the shares of SYS stock subject to the escrow is then registered under the Securities Act of 1933, as amended, SYS may direct the Escrow Agent to sell an adequate number of shares such that the disbursement to SYS may be made in cash. If the resale of such shares is not then so registered, the disbursement to SYS shall be made in shares valued in the manner described in Section 8.2(a) of the Merger Agreement.

SYS and the Polexis Principal Stockholders shall, jointly and severally, indemnify and hold the Escrow Agent harmless from any and all liability and expenses (including, without limitation, its attorney's fees and expenses of litigation) which may arise out of or result from this Escrow Agreement or any action taken or omitted to be taken by it as Escrow Agent in accordance with this Escrow Agreement, as the same may be amended, modified or supplemented, except with respect to any such liability and expense as may result from the gross negligence or willful misconduct of the Escrow Agent.

(c) The Escrow Agent shall be entitled to rely and shall be protected in acting in reliance upon any instructions or directions furnished to it in writing jointly by SYS and the Polexis Principal Stockholders or pursuant to any provision of this Escrow Agreement and shall be entitled to treat as genuine, and as the document it purports to be, any letter, paper or other document furnished to it by SYS or the Polexis Principal Stockholders and reasonably believed by it to be genuine and to have been signed and presented by the proper party or parties.

Any such successor Escrow Agent shall deliver to SYS and the Polexis Principal Stockholders a written instrument accepting such appointment hereunder, and thereupon it shall succeed to all the rights and duties of the Escrow Agent hereunder and shall be entitled to receive the Escrow Amount held by the predecessor Escrow Agent hereunder.

(e) The Escrow Agent may consult with counsel to be selected and employed by it and shall be fully protected with respect to any action under this Escrow Agreement taken or suffered in good faith by the Escrow Agent in accordance with the opinion of such counsel.

9. Notices. All notices and other communications hereunder (each, a "Notice") shall be in writing and shall be deemed given if delivered personally, sent by facsimile (with written confirmation of successful delivery) or dispatched by a nationally recognized overnight courier service to the parties at the following addresses (or at such other address for a party as shall be specified by like Notice from such party to the other parties hereto).

CONDITIONS OF ACCEPTANCE

IN CONSIDERATION OF THE ACCEPTANCE OF THIS ESCROW BY UNION BANK OF CALIFORNIA, N.A., all of the parties agree that said Acceptance is predicated upon the following conditions and stipulations and that any modification of escrow instructions shall also be subject to the following provisions:

1. In the event of any conflict between the Escrow Agreement (hereinafter called the "Escrow Agreement") and these Conditions of Acceptance, the latter shall prevail.

2. The duties of the Escrow Agent are only such as are specifically provided herein and in the Escrow Agreement, being purely ministerial in nature, and the Escrow Agent shall incur no liability whatsoever, except for willful misconduct or gross negligence, so long as it has acted in good faith.

3. The Escrow Agent shall be under no responsibility in respect of any of the items deposited with it other than to faithfully follow the instructions contained herein and in the Escrow Agreement. The Escrow Agent may advise with counsel and shall be fully protected in any action taken in good faith in accordance with such advice. The Escrow Agent shall not be required to defend any legal proceedings which may be instituted against it in respect of the subject matter of the Escrow unless requested to do so by the parties to the Escrow and indemnified as provided in the Escrow Agreement. The Escrow Agent shall not be required to institute legal proceedings of any kind.

4. The Escrow Agent shall have no responsibility for the genuineness or validity of any document or other item deposited with it nor for the identity or legal capacity of any party involved nor for the sufficiency of any agency nor for the genuineness of signatures to any papers or documents nor for the negotiability or marketability of any item deposited with it nor for any delay of this Escrow due to any cause beyond its control, and it shall be fully protected in acting in accordance with any written instructions given to it hereunder or under the Escrow Agreement and believed by it to have been signed by the proper parties.

5. The Escrow Agent shall be liable for only such funds and instruments as are actually deposited and received by it for the purpose of this Escrow and shall have a lien on all funds and instruments deposited with it for the purpose of securing any fees, costs or other charges incurred by it hereunder.

6. The Escrow Agent shall not be liable for the payment of any funds in the event it shall be prevented from making payment by operation of law or otherwise.

7. Provided the terms of the Escrow can be complied with, the Escrow Agent will not withhold completion and settlement thereof, unless restrained by order of court or served with some other similar legal proceeding, and in so doing, the Escrow Agent will not become liable to the undersigned, or to any other person, for its failure or refusal to comply with conflicting or adverse claims or demands.

8. In the event of a dispute between the parties, an ambiguity in the provisions governing the Escrow or uncertainty on the part of the Escrow Agent as to how to proceed with the Escrow, such that the Escrow Agent, in its sole and absolute judgment, deems it necessary for its protection so to do, the Escrow Agent may (a) refrain from taking any action other than to safely keep the items deposited hereunder until it shall have received joint written instructions from the parties to the Escrow, or (b) deposit the escrowed items into a court of competent jurisdiction and thereupon have no further duties or responsibilities in connection therewith.

9.

FOUNDERS' ESCROW AGREEMENT

This Founders' Escrow Agreement (the "Founders' Escrow Agreement") is made and entered into as of March 31, 2004, by and among SYS, a California corporation ("SYS"), ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, an individual resident in San Diego County, California ("Glasgow"), and Union Bank of California, N.A. (the "Escrow Agent"). Glasgow is sometimes referred to in this document as the "Founder."

PRELIMINARY STATEMENTS

WHEREAS, pursuant to that certain Agreement and Plan of Merger (the "Merger Agreement"), made and entered into as of March 31, 2004, by and among SYS, Shadow Research International, Inc., Polexis, Inc. ("Polexis") and certain Polexis Principal Stockholders, Shadow Research International, Inc. intends to merge with and into Polexis, as more fully set forth in the Merger Agreement; and

WHEREAS, it is a condition to the consummation of the merger under the Merger Agreement that this Founders' Escrow Agreement be entered into by and among SYS, the Founder and Escrow Agent. Capitalized terms used in this Founders' Escrow Agreement without definition shall have the meanings given to them in the Merger Agreement.

NOW, THEREFORE, in consideration of these premises and the mutual and dependent promises hereinafter set forth, the parties hereto agree as follows:

1. Deposit in Escrow. Simultaneous with the execution and delivery of this Founders' Escrow Agreement on the Closing Date, and pursuant to Section 2.1(c) of the Merger Agreement, SYS has deposited with the Escrow Agent, and the Escrow Agent hereby acknowledges receipt of 25,381 shares of SYS common stock (together with any proceeds of such shares, the "Founder's Escrow Stock Amount" or the "Founder's Escrow Amount"), via physical delivery of certificates representing such shares, together with stock powers duly endorsed in blank by the Founder. The Escrow Agent shall vote the Founder's Escrow Stock Amount in accordance with written instructions to be received from SYS.

2. Escrow Account. The Founder's Escrow Amount shall be deposited by the Escrow Agent, immediately upon receipt, in an account (the "Escrow Account") for the benefit of SYS and the Founder.

3. Investment of Escrow Amount. Except as otherwise instructed in writing by all of the parties hereto, any cash that may comprise the Founder's Escrow Amount shall be deposited by the Escrow Agent, until depletion, uninvested in an escrow account. The Escrow Agent is authorized to disburse, in accordance with its customary procedures, cash comprising all or part of the Founder's Escrow Amount to provide for any payments required to be made pursuant to this Founders' Escrow Agreement.

4. Disbursements to the Founder. Except with respect to any Disputed Amounts as to which Claims are pending or have been paid pursuant to Section 5 below, the Escrow Agent shall disburse from the Escrow Account, to the Founder, on the earlier of nine months following the closing of the Merger or the date (as such date is specified to the Escrow Agent by SYS) on which the Founder has been in the full-time employ of SYS or any affiliate of SYS for six (6) months following such closing (or, if the Escrow Agent is closed on such date, the next day upon which the Escrow Agent is open for business), the remaining balance of the Escrow Amount, less 50% of the Escrow Agent Expenses. The "Escrow Agent Expenses" means the aggregate amount of any fees or expenses and related disbursements incurred by the Escrow Agent in carrying out its obligations hereunder prior to such date.

5. Claims. In the event that a Founder shall fail to be an employee of SYS or any affiliate of SYS for at least six (6) months during the nine (9) months subsequent to the closing of the Merger, then SYS shall deliver a Notice to the Founder and to the Escrow Agent (a "Claim Notice"), specifying

E-1-1

the event giving rise to the Notice and requesting that the Escrow Agent make a disbursement to SYS of the entire amount of the shares and any other assets in the Escrow Account.

(a) The Founder shall have ten calendar days following receipt of a Claim Notice (the "Objection Period") to deliver a Notice to the Escrow Agent and SYS (an "Objection Notice") objecting to all or any portion of the amount specified in the Claim Notice.

(b) If the Escrow Agent does not receive a timely Objection Notice, then the Escrow Agent shall pay the amount of the disbursement set forth in the Claim Notice from the Founder's Escrow Amount.

(c) If the Escrow Agent does receive a timely Objection Notice, the Escrow Agent shall segregate and hold, separate from remainder of the Founder's Escrow Amount, that portion of the Founder's Escrow Amount which is attributable to the Claim Notice (a "Disputed Amount").

(d) The Escrow Agent shall retain any Disputed Amount until the earlier of the receipt by the Escrow Agent of (i) a joint Notice from SYS and the Founder indicating that the objection has been resolved and instructing the Escrow Agent to disburse or credit the Disputed Amount, or any applicable portion thereof, to SYS or the Founder, respectively, or (ii) a true and correct copy of a final, non-appealable decision of a court or arbitrator relating to such Claim Notice (a "Claim Judgment"), ordering the Escrow Agent to disburse the Disputed Amount, at which time the Escrow Agent shall promptly disburse the Disputed Amount in accordance therewith.

6. Term and Termination. This Founders' Escrow Agreement shall expire, and the Escrow Account shall be closed, on the date upon which all of the Escrow Amount has been disbursed pursuant to this Agreement.

7. Concerning the Escrow Agent.

(a) The duties and responsibilities of Escrow Agent shall be limited to those expressly set forth in this Founders' Escrow Agreement and the Acceptance of Escrow, the form of which is attached hereto as Exhibit A (the "Acceptance of Escrow"). With the exception of this Agreement and the Acceptance of Escrow, the Escrow Agent is not responsible for, or chargeable with knowledge of, any terms or provisions contained in any underlying agreement referred to in this Agreement or any other separate agreements and understandings between the parties. The Escrow Agent shall not be liable for the accuracy of any calculations or the sufficiency of funds for any purpose.

(b) The Escrow Agent shall not be liable to anyone whatsoever by reason of any error or judgment or for any act done or step taken or omitted by it in good faith or for any mistake of fact or law or for anything which it may do or refrain from doing in connection herewith unless caused by or arising out of its own gross negligence or willful misconduct. SYS and the Founder shall, jointly and severally, indemnify and hold the Escrow Agent harmless from any and all liability and expenses (including, without limitation, its attorney's fees and expenses of litigation) which may arise out of or result from this Founders' Escrow Agreement or any action taken or omitted to be taken by it as Escrow Agent in accordance with this Founders' Escrow Agreement, as the same may be amended, modified or supplemented, except with respect to any such liability and expense as may result from the gross negligence or willful misconduct of the Escrow Agent.

(c) The Escrow Agent shall be entitled to rely and shall be protected in acting in reliance upon any instructions or directions furnished to it in writing jointly by SYS and the Founder or pursuant to any provision of this Founders' Escrow Agreement and shall be entitled to treat as genuine, and as the document it purports to be, any letter, paper or other document furnished to it by SYS or the Founders and reasonably believed by it to be genuine and to have been signed and presented by the proper party or parties.

E-1-2

(d) The Escrow Agent, or any successor to it hereafter appointed, may at any time resign by giving a Notice to SYS and the Founder and shall be discharged from its duties hereunder upon the appointment of a successor Escrow Agent as hereinafter provided or upon the expiration of thirty (30) days after such Notice is given. In the event of any such resignation, a successor Escrow Agent, which shall be a bank or trust company organized under the laws of the State of California and having a combined capital and surplus of not less than $10,000,000, shall be jointly appointed by SYS and the Founder. Any such successor Escrow Agent shall deliver to SYS and the Founder a written instrument accepting such appointment hereunder, and thereupon it shall succeed to all the rights and duties of the Escrow Agent hereunder and shall be entitled to receive the Escrow Amount held by the predecessor Escrow Agent hereunder.

(e) The Escrow Agent may consult with counsel to be selected and employed by it and shall be fully protected with respect to any action under this Founders' Escrow Agreement taken or suffered in good faith by the Escrow Agent in accordance with the opinion of such counsel.

(f) The Escrow Agent shall receive compensation for its services at its customary rates as in effect from time to time. Such compensation, along with any other fees or expenses and related disbursements incurred by the Escrow Agent in carrying out its obligations hereunder prior to such date, shall be paid 50% by the Founder as set forth in Section 4 above and 50% by SYS; provided, to the extent the Escrow Amount is insufficient to pay the Founder's share of the Escrow Agent's compensation, fees, expenses or related disbursements hereunder, the Founder shall pay such amount to the Escrow Agent.

All notices and other communications hereunder (each, a "Notice") shall be in writing and shall be deemed given if delivered personally, sent by facsimile (with written confirmation of successful delivery) or dispatched by a nationally recognized overnight courier service to the parties at the following addresses (or at such other address for a party as shall be specified by like Notice from such party to the other parties hereto).

4.2.4 Accrued but unused personal leave shall be paid out in accordance with legal requirements. No personal leave or other benefits shall continue to accrue during the Severance Period.

4.2.5 Notwithstanding the foregoing, if any amounts due to Employee pursuant to this Agreement are determined to be "Parachute Payments" as such term is defined in Section 280G of the Internal Revenue Code of 1986, as amended (the "Code"), and the regulations promulgated thereunder, then the total compensation paid to Employee pursuant to this Agreement, together with any other payment or the value of any benefit received or to be received by the Employee which is treated as a Parachute Payment shall not exceed 2.99 times the Employee's Base Amount (as such term is defined in Section 280G of the Code). In the event a reduction of the payments set forth in this Agreement is required pursuant to this Section, the Employee may select the compensation which will be reduced in order to fall within the 2.99 times Base Amount limitation.

4.3 Resignation with Cause. If Employee resigns his employment because (a) his position or duties are modified by the Company to such an extent that his duties are substantially no longer consistent with the position for which he was employed pursuant to this Agreement, or (b) there has been a material breach by the Company of a material term of this Agreement which continues uncured following fourteen (14) days after written notice by Employee to the Company of such breach, then Employee will be entitled to the severance benefits set forth in subsection 4.2, consistent with the terms of said provision.

4.4 Termination Due to Death or Disability. This Agreement will immediately terminate upon Employee's death. This Agreement will terminate upon Employee's Disability (as defined below), when consistent with state and federal law. In the event of Employee's termination due to death or Disability, Employee, or Employee's heirs, personal representatives or estate, as the case may be, will be entitled to receive only the standard entitlements and those benefits available under any applicable Company plan or insurance policy, subject to such plan or policy requirements, along with accrued unpaid Base Salary and personal time. All other Company obligations to Employee pursuant to this Agreement will become automatically terminated and completely extinguished. In addition, neither Employee nor Employee's heirs, personal representatives or estate will be entitled to receive Severance Payments or other benefits described in subsection 4.2 above.

4.4.1 For the purpose of this Agreement only, the Company will not deem this Agreement terminated due to Employee's Disability unless he has been unable to perform his duties hereunder for three (3) consecutive months or ninety (90) days in any twelve (12) consecutive month period due to Employee's medical or mental condition, as determined in good faith by the Board of Directors of the Company.

5.2 Confidential/Trade Secret Information/Non-Disclosure.

5.2.1 Confidential/Trade Secret Information Defined. During the course of Employee's employment, Employee will have access to various confidential/trade secret information of the Company. "Confidential/trade secret information" is information which is not generally known to the public and, as a result, is of economic benefit to the Company in the conduct of its business. Employee and the Company agree that the term "confidential/trade secret" includes but is not limited to all information developed or obtained by the Company, including its affiliates, and predecessors, and comprising the following items, whether or not such items have been reduced to tangible form (e.g., physical writing, computer hard drive, disk, tape, etc.): all methods, techniques, processes, ideas, research and development, product designs, engineering designs, plans, models, production plans, business plans, add-on features, trade names, service marks, slogans, forms, pricing structures, menus, business forms, marketing programs and plans, layouts and designs, financial structures, operational methods and tactics, cost information, the identity of and/or contractual arrangements with suppliers and/or vendors, accounting procedures, and any document, record or other information of the Company relating to the above.

It does not include any information which (a) was in the lawful and unrestricted possession of Employee prior to its disclosure to Employee by the Company or its affiliates or predecessors, (b) is or becomes generally available to the public by lawful acts other than those of Employee after receiving it, or (c) has been received lawfully and in good faith by Employee from a third party who is not and has never been an employee of the Company or its affiliates or predecessors and who did not derive it from the Company or its affiliates or predecessors.

5.2.2 Restriction on Use of Confidential/Trade Secret Information. Employee agrees that his use of confidential/trade secret information is subject to the following restrictions for an indefinite period of time so long as the confidential/trade secret information has not become generally known to the public:

Employee further agrees that he shall surrender to the Company all documents and materials in his possession or control which contain confidential/trade secret information and which are the property of the Company upon the termination of this Agreement, and that he shall not thereafter retain any copies of any such materials.

5.2.3 Non-Solicitation of Customers/Prohibition Against Unfair Competition. Employee agrees that at no time after his employment with the Company will he engage in competition with the

F-4

Company while making any use of the Company's confidential/trade secret information. In addition, Employee agrees that, for a period of one (1) year after the termination of this Agreement, he will not directly or indirectly accept or solicit, whether as an employee, independent contractor or in any other capacity, the business of any customer of the Company with whom Employee worked or otherwise had access to the Company's confidential/trade secret information pertaining to its business with that customer during the last two (2) years of his employment with the Company.

5.3 Conflict of Interest. During Employee's employment with Company, Employee must not engage in any work, paid or unpaid, that creates an actual conflict of interest with Company. Such work shall include, but is not limited to, directly or indirectly competing with Company in any way, or acting as an officer, director, employee, consultant, controlling or 5% stockholder, volunteer, lender, or agent of any business enterprise of the same nature as, or which is in direct competition with the business in which Company is now engaged or in which Company becomes engaged during Employee's employment with Company, as may be determined by the Board of Directors in its sole discretion. If the Board of Directors believes such a conflict exists during Employee's employment, the Board of Directors may ask Employee to choose to discontinue the other work or resign employment with Company. In addition, Employee agrees not to refer any client or potential client of Company to competitors of Company without obtaining the Company's prior written consent during Employee's employment. Any termination of Employee's employment due to violation of this subsection is considered "With Cause" for the purposes of section 4.1 above.

5.4 Non-Solicitation During Employment. Employee shall not during his employment interfere with or disrupt or attempt to disrupt Employer's business relationship with its customers or suppliers or solicit any of the employees of Employer to leave the employ of Employer.

5.5 Non-Solicitation of Employees. Employee agrees that, for one (1) year following the termination of his employment, he shall not, directly or indirectly, ask or encourage any of the Company's employees to leave their employment with the Company or solicit any of the Company's employees for employment.

5.6 Breach of Provisions. If the Employee breaches any of the provisions of this Section 5, or in the event that any such breach is threatened by the Employee, in addition to and without limiting or waiving any other remedies available to the Company at law or in equity, the Company shall be entitled to immediate injunctive relief in any court, domestic or foreign, having the capacity to grant such relief, to restrain any such breach or threatened breach and to enforce the provisions of this Section 5. The Employee acknowledges and agrees that there is no adequate remedy at law for any such breach or threatened breach and, in the event that any action or proceeding is brought seeking injunctive relief, the Employee shall not use as a defense thereto that there is an adequate remedy at law. In addition, if the Employee breaches any of the provisions of this Section 5, any and all Severance Payments and benefit obligations under subsections 4.2 and 4.3 will cease and be extinguished in their entirety and the Company will have no further obligations in that regard.

5.7 Reasonable Restrictions. The parties acknowledge that the foregoing restrictions, as well as the duration and the territorial scope thereof as set forth in this Section 5, are under all of the circumstances reasonable and necessary for the protection of the Company and its business.
