PRELIMINARY STATEMENTS

WHEREAS, the respective Boards of Directors of SYS, Subcorp and Antin have determined that the merger of Antin with and into Subcorp, 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, Antin, and the 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 California General Corporation Law (the "CGCL"), Antin shall be merged with and into Subcorp at the Effective Time. As a result of the Merger, the separate corporate existence of Antin shall cease and Subcorp shall continue its existence under the laws of the State of California as a wholly-owned subsidiary of SYS. Subcorp, 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 following the later of the Closing Date and the approval of the listing of shares to be issued by SYS in the Merger by the American Stock Exchange, the parties shall cause the Merger to be consummated by filing 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 Subcorp (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 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 Antin and specified in 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, Luce, Forward, Hamilton & Scripps LLP ("Luce Forward"), 600 West Broadway, Suite 2600, San Diego, California 92101, 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 IV have been satisfied or waived, or at such other date as SYS and Antin 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 8:00 a.m., Pacific Standard Time, on January 3, 2005.

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

1.4 Articles of Incorporation and Bylaws. The Articles of Incorporation of Subcorp, as in effect immediately prior to the Effective Time, shall be the Articles of Incorporation of the Surviving Corporation and the Bylaws of Subcorp, as 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.

ARTICLE II
CONVERSION OF SECURITIES AND ESCROW

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 Antin or their respective stockholders, each share of Antin Capital Stock issued and outstanding immediately prior to the Effective Time shall be converted into, and shall represent the right to receive, that portion of the aggregate amount of up to $2,100,000 (such aggregate amount, the "Merger Consideration"), to which such share is entitled, with $360,000 payable in cash (the "Cash Consideration"), and up to $1,740,000, payable in the form of up to 696,000 shares of restricted SYS Common Stock (valued at $2.50 per share) (the "Stock Consideration"). The Merger Consideration shall be paid and allocated and distributed among the Stockholders as set forth on Schedule 2.1.

2.2 Subcorp Stock. Each share of capital stock of Subcorp outstanding at the Effective Time shall remain issued and outstanding following the Effective Time.

2.3 Fractional Shares; Adjustments.

2.3.1 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.

2.3.2 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 Antin Capital Stock whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.1, upon presentation of such fractional interest represented by an appropriate Certificate for Antin Capital Stock to SYS, 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 Antin Capital Stock for which Certificates have been surrendered shall be appropriately adjusted to provide to the Stockholders the same economic effect as contemplated by this Agreement. The fractional share interests of each Stockholder will be aggregated, and no 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.

2.4.1 Exchange at Closing and at the Effective Time and Possible Subsequent Delivery of SYS Shares. At the Closing, each Antin Stockholder shall deliver (i) the Certificate or Certificates representing such Antin Stockholder's shares of Antin 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 (medallion guaranteed) with respect to that Stockholder's shares of SYS Common Stock which are to be deposited with the Escrow Agent, and in exchange for such delivery shall receive as soon as possible after the Effective Time (i) the Cash Consideration to which such Antin Stockholder is entitled as set forth on Schedule 2.1, and (ii) the Stock Consideration to which such Antin Stockholder is entitled as set forth on Schedule 2.1, payable by delivery of a single stock certificate naming the Escrow Agent as the holder thereof. Subsequent to the Effective Time, SYS shall deliver to the Stockholders and to Escrow such additional Stock Consideration to which the Stockholders may be entitled pursuant to Schedule 2.1.

2.4.2 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, and (ii) 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.

2.4.3 No Further Ownership Rights in Antin Capital Stock. All Merger Consideration issued and/or paid upon surrender of Certificates (or affidavit) 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 Antin Capital Stock represented thereby, and, as of the Closing, the stock transfer books of Antin shall be closed and there shall be no further registration of transfers on the stock transfer books of Antin of shares of Antin Capital Stock outstanding immediately prior to the Closing. If, after the Closing, Certificates are presented to Antin or the Surviving Corporation for any reason, they shall be cancelled.

2.4.4 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.

2.4.5 Withholding Rights. Each of the Surviving Corporation and SYS shall be entitled to deduct and withhold from the Cash Consideration otherwise payable pursuant to this Agreement to any holder of shares of Antin Capital Stock, such amounts as it is required to deduct and withhold with respect to the making of such payment or any other payment by Antin, the Surviving Corporation or SYS, 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 Antin 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 Antin Capital Stock evidence reasonably satisfactory to such holder that payment was duly remitted to the appropriate Governmental Authority. The parties hereto anticipate that no Stock Consideration and substantially all of the Cash Consideration will be withheld and paid to Governmental Authorities pursuant to this Section 2.4.5. Any Cash Consideration which is not so withheld shall be distributed at Closing in accordance with Schedule 2.1.

2.4.6 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.

2.5.1 Escrow Agreement. On or prior to the Closing Date, SYS and the Stockholders 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 A hereto (the "Escrow Agreement").

2.5.2 Deposit of Escrow Consideration. As soon as possible after the Effective Time, SYS shall deliver to the Escrow Agent, for immediate deposit into the Escrow Account, 220,000 shares of restricted SYS Common Stock, to be allocated among the Stockholders in accordance with Schedule 2.1, by delivery of one certificate issued in the name of the Escrow Agent as Escrow Agent, accompanied if requested by the Escrow Agent by stock powers duly endorsed in blank by the Antin Stockholders. Any such endorsement shall be medallion guaranteed. Such shares shall constitute part of the "Escrow Consideration," which may also be referred to herein as the "Escrow Stock Consideration." Any remaining part of the Escrow Consideration, which may consist of up to 128,000 shares of restricted SYS Common Stock, shall be determined in accordance with Schedule 2.1 and shall be delivered by SYS to the Escrow Agent upon the later of the approval of the listing of shares to be issued by SYS in the Merger by the American Stock Exchange on delivery of the Closing Date Balance Sheet to the Stockholders by SYS and shall be allocated to Miller in accordance with Schedule 2.1.

2.5.3 Disbursement of Merger Consideration. All of the Escrow Consideration deposited in the Escrow Account shall be available, in accordance with this Agreement and the Escrow Agreement, to secure, and to provide recourse for, the rights of SYS as described in Schedule 2.1 and to provide recourse to SYS for any breach of the representations and warranties of the Antin Stockholders under Article IV hereof and pursuant to Article VIII hereof, and shall be paid to the Antin Stockholders only in accordance with and subject to the terms and conditions set forth herein and in the Escrow Agreement.

2.6 Internal Revenue Code Election. At its option, following the Closing Date SYS may make an election under Section 338 of the Internal Revenue Code of 1986, as amended, with regard to the Merger, provided that such election has no adverse effect upon any of the Antin stockholders.

5.1.2 Public Announcements. The initial press release concerning the transactions contemplated hereby shall be a joint press release and shall be issued, upon the mutual agreement of Miller and SYS, on or after the date of this Agreement. SYS and the Stockholders shall consult with each other before issuing, and give each other the opportunity to review and comment upon, any other press release or public statements with respect to the transactions contemplated by this Agreement, and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by Applicable Law, court process or by obligations pursuant to any listing agreement of SYS with any national securities exchange or national securities quotation system.

5.1.3 Notices of Certain Events. Each party hereto shall promptly notify the other parties in writing of:

5.2 Covenants of SYS.

5.2.1 Employees and Employee Benefits. From and after the Closing, each continuing Antin employee shall be entitled to participate in all SYS employee benefit plans in a manner and to the extent consistent with their position. From and after the Closing, SYS shall exercise its best efforts to treat all service by Antin Employees with Antin (or any predecessor thereto) prior to the Closing for all purposes as service with SYS (except for purposes of benefit accrual under defined benefit pension plans or to the extent such treatment would result in duplicative accrual on or after the Closing Date of benefits for the same period of service), and, with respect to any medical or dental benefit plan in which Antin Employees participate after the Closing Date, SYS shall exercise its best efforts to waive or cause to be waived any pre-existing condition exclusions and actively-at-work requirements (provided, however, that no such waiver shall apply to a pre-existing condition of any Antin Employee who was, as of the Closing, excluded from participation in a Antin Plan by virtue of such pre-existing condition), and shall exercise its best efforts to provide that any covered expenses incurred on or before the Closing during the plan year of the applicable Antin Plan in which the Closing Date occurs by a Antin Employee or a Antin Employee's covered dependent shall be taken into account for purposes of satisfying applicable deductible, coinsurance and maximum out-of-pocket provisions after the Closing Date to the same extent as such expenses are taken into account for the benefit of similarly situated employees of SYS and subsidiaries of SYS.

5.2.2 Registration.

(i) SYS will use its best efforts to attempt to register for resale with the SEC all SYS shares issued pursuant hereto. Following the effectiveness of the registration, and through the twelve month anniversary of the Closing Date, SYS will not voluntarily terminate the registration and, to the extent that the registration statement or the prospectus which is a part thereof requires amendment or supplement under the Securities Act of 1933 and the rules adopted thereunder, will exercise reasonable commercial efforts to expeditiously amend or supplement such registration statement, including the prospectus which is a part thereof.

(ii) At any time that SYS determines to register any of its SYS Common Shares, or to amend any filed registration which is not yet effective, either for its own account or for the account of a holder of SYS Common Shares or as a result of a holder of SYS Common Shares exercising demand registration rights, other than a registration (A) relating solely to SYS Common Shares registered on Form S-4 or Form S-8 (or any successor forms), or (B) with respect to which the SYS Common Shares held by the Antin Stockholders would not be legally permitted to be included, then SYS shall:

(A) at least 15 days prior to the filing of a registration statement, other than as set forth in (ii)(A) or (B) above, promptly give each Antin Stockholder (each, an "Eligible Stockholder") written notice thereof by registered or certified mail, courier or personal delivery; provided that no such notice shall be required in a non-underwritten registration, and all of such stock shall be registered thereon; and

(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 (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.

(iii) 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 (ii)(A) above. In such event the right of any Eligible Stockholder to registration pursuant to subsection (ii) 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 5.2.2, 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 5.2.2, 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.

(iv) SYS shall provide to each Eligible Stockholder 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.

(v) SYS shall have the right to terminate or withdraw any registration initiated by it under this Section 5.2.2 prior to the effectiveness of such registration, but without prejudice to its obligation pursuant to this Section 5.2.2.

(vi) SYS shall bear the expenses associated with the registration of Registrable Securities pursuant to this Section 5.2.2 exclusive of underwriters' and brokers' discounts and commissions and expenses of the Stockholders' legal counsel.

5.3.1 Conduct of Antin's Operations.

5.3.2 Access to Information; Confidentiality. Upon reasonable notice, the Stockholders shall cause Antin to afford to the officers, employees, accountants, counsel, financial advisors and other representatives of SYS reasonable access during normal business hours, during the period prior to the Closing Date, to such of its properties, books, contracts, commitments, records, all other information and data, officers and employees as SYS may reasonably request and, during such period, Antin shall furnish promptly to SYS (a) a copy of each report, schedule, and other document filed, published, 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 Antin may restrict the foregoing access to the extent that it reasonably concludes, after consultation with outside legal counsel, that (i) any Applicable Law requires Antin 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 Antin is a party.

5.3.3 No Solicitation. Until the Effective Time or the termination of this Agreement:

(i) Antin and the Stockholders will not, and will not permit or cause any Subsidiary or any of the directors or officers of Antin or any Subsidiary, and will direct Antin's employees, agents and representatives not to, directly or indirectly, solicit, initiate, encourage, or furnish or disclose non-public information in furtherance of, or otherwise facilitate any inquiries that may be reasonably expected to lead to, the making of any proposal or offer with respect to a merger, reorganization, share exchange, consolidation, or similar transaction involving, or any purchase of 10% or more of the assets or any equity of, Antin or any Subsidiary or any other business combination other than the transactions contemplated by this Agreement (any such proposal or offer, an "Acquisition Proposal").

(ii) Antin and the Stockholders 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) Antin and the Stockholders 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.

5.3.4 Release. Each Stockholder (who for purposes of this Section 5.3.4 shall be referred to as a "Releasor" on behalf of Releasor and Releasor's successors, heirs, and assigns, hereby fully and forever releases and discharges Antin and SYS and their respective successors, heirs, and assigns, and their respective officers, directors, agents, representatives, employees and attorneys from any and all claims, demands, actions, agreements, suits, causes of action, obligations, controversies, debts, costs, attorneys' fees, expenses, damages, judgments, orders and liabilities of whatever kind or nature in law, equity or otherwise, past, present or future, known or unknown, suspected or unsuspected, from the beginning of time through execution of this Agreement, excepting only any claims arising out of this Agreement and enforcement thereof and, in the case of Miller, any debts or liabilities which may be shown as owing to Miller on the Closing Balance Sheet (collectively, the "Claims").

Each Releasor acknowledges that there is a possibility that subsequent to the execution of this Agreement, he or she will discover facts or incur or suffer claims that were unknown or unsuspected at the time this Agreement was executed, and which if known by such Releasor at that time may have materially affected such Releasor's decision to execute this Agreement. Each Releasor acknowledges and agrees that by reason of this Section 5.3.4, he or she is assuming any risk of such unknown facts and such unknown and unsuspected claims.

Each Releasor has been advised of the existence of Section 1542 of the California Civil Code ("Section 1542"), which provides:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

Notwithstanding such provisions, this Section 5.3.4 shall constitute a full release in accordance with its terms. Each Releasor hereby knowingly and voluntarily waives the provisions of Section 1542, as well as any other statute, law or rule of similar effect.

(ii) For a period of two (2) years after the date of Closing of the Merger, each Stockholder agrees that he or she will not, directly or indirectly (whether on his or her own behalf or as an owner, parent, stockholder, partner, joint venturer, investor, member, officer, director, agent, independent contractor, associate, executive, consultant or licensor) solicit or encourage to leave the employ of Antin or its subsidiaries any employee or independent contractor of Antin or its subsidiaries and affiliates.

(iii) Each Stockholder acknowledges that the restrictions and covenants set forth above are reasonably necessary to protect the goodwill and other legitimate business interests of SYS and its subsidiaries, including the goodwill acquired by SYS as a consequence of the closing of the Merger described in this Agreement, and are not overbroad, overlong, or unfair (including in duration and scope).

9.6 Governing Law; Venue.

9.6.1 This Agreement shall be governed by the laws of the State of California without regard to its conflict of laws rules, and any action arising out of or in connection with this Agreement or the Merger shall be brought only in the appropriate federal or state court in San Diego County, California. Each of the parties hereto agrees that a final judgment in any action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

9.6.2 Each of the parties hereto irrevocably consents to the service of any summons and complaint and any other process in any other action or proceeding relating to this Agreement, on behalf of itself or its property, by the personal delivery of copies of such process to such party. Nothing in this Section 9.6 shall affect the right of any party hereto to serve legal process in any other manner permitted by law.

9.7 Arbitration. The parties to this Agreement shall submit to binding arbitration before a single, neutral arbitrator of any dispute, controversy or claim arising out of, or relating to, the transactions contemplated by this Agreement or any breach hereof, provided, however, that the parties retain their right to, and shall not be prohibited, limited or in any other way restricted from, seeking or obtaining equitable relief from a court having jurisdiction over the parties. Such arbitration shall be governed by and conducted through the American Arbitration Association in accordance with the Commercial Dispute Resolution Procedures. The arbitration hearing shall be held in San Diego, California at a place to be designated by the parties or, in the absence of their agreement, by the arbitrator.

9.8 Specific Performance. The transactions contemplated by this Agreement are unique. Accordingly, each of the parties acknowledges and agrees that, in addition to all other remedies to which it may be entitled, each of the parties hereto is entitled to a decree of specific performance, provided such party is not in material default hereunder. The party prevailing in any proceeding seeking such a decree shall be entitled to payment of all reasonable legal fees and expenses by the non-prevailing party.

Additionally, notwithstanding the foregoing or anything to the contrary contained in this Agreement, SYS is specifically permitted to adopt a holding company structure pursuant to Section 251(g) of the DGCL and assign this Agreement to the holding company or consummate SYS's previously approved reincorporation into the State of Delaware, in which case the references herein to receipt and registration of actual and underlying SYS shares shall instead refer to the equivalent shares of the Delaware corporation.

9.10 Expenses. All costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby and thereby shall be paid by the party incurring such expenses.

9.11 Severability. The invalidity or unenforceability in whole or in part of any covenant, promise or undertaking, or any section, subsection, sentence, clause, phrase, word, or any of the provisions of this Agreement will not affect the validity or enforceability of the remaining portions of this 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 Amendment. This Agreement may be amended only by agreement in writing executed by all of the parties hereto; provided, however, that SYS and Antin shall be entitled to provide written statements regarding new information as to the Antin Disclosure Schedule, respectively, without the written consent of the other parties hereto.
