AGREEMENT

     Section 1. Definitions. Whenever used in this Agreement, the following terms shall have the following respective meanings:

          1.1. “Additional Holder” and “Additional Holders” mean the additional holder or holders, as the case may be, of Shares that become a party to this Agreement from time to time by signing an Additional Holder Signature Page in the form attached hereto as Exhibit A. Specifically excepted from this definition is any holder that is a successor-in-interest to all or some of the Shares held by Compass, notwithstanding that any successor-in-interest shall sign an Additional Holder Signature Page (any reference to Compass herein shall be a reference to any

and/or the benefit of one or more of his or her spouse or lineal descendants; (iii) a transfer by will or intestate succession to a Stockholder’s spouse or lineal descendants or such Stockholder’s executor, administrator or testamentary trustee for the benefit of one or more of such Stockholder’s spouse or lineal descendants; (iv) a transfer from a trust for the benefit of a Stockholder and/or one or more of his or her spouse or lineal descendants to such Stockholder’s spouse and/or lineal descendants; (v) a transfer to any members of the Board of Directors of the Company that are nominees of Compass; (vi) a transfer to any director, officer or employee of The Compass Group International LLC; (vii) a transfer to a Person in which a Compass Affiliate is directly or indirectly the beneficial owner of five percent or more of the equity securities of such Person, (viii) a transfer by Madison to The New York Life Insurance Company or any of its majority-owned subsidiaries, provided that Madison shall provide the Company with written notice of such transfer within sixty (60) days of the transfer, and (ix) a transfer by Allied to an Allied Affiliate with the prior written consent of Compass, which consent shall not be unreasonably withheld. The Shares transferred to any such permitted transferee shall remain subject to the provisions of this Agreement and such permitted transferee shall become a Stockholder for purposes of this Agreement. Every such transferee shall observe and comply with this Agreement and with all obligations and restrictions imposed hereby and shall, at the request of Compass or any Stockholder, execute an Additional Holder Signature Page.

          2.4. Drag Along/Tag Along Rights. Compass shall be permitted to sell, assign, convey, transfer, encumber or in any other manner dispose of any or all of the Shares held or owned by it, subject, however, (i) that Shares transferred to any person shall remain subject to the provisions of this Agreement and such transferee shall become a Stockholder for purposes of this Agreement and (ii) in the case of sales or other transfers for value, to the following restrictions:

          (a) Disposition Notice. If Compass proposes at any time to sell or otherwise transfer for value, whether in a single transaction or in a series of transactions, including any redemption or repurchase of Shares by the Company, but excluding Exempt Transfers, (i) in the context of Section 2.4(b), substantially all of its Shares, or (ii) in the context of Section 2.4(c), more than 5% of the then outstanding Shares of the Company (each a “Proposed Sale”) to any person, Compass shall send written notice (the “Disposition Notice”) to the other Stockholders specifying the identity and address of such person, the number of Shares to be sold, the proposed per Share sale price, the form of consideration to be paid, any other material terms and conditions of the Proposed Sale, and, for bona fide sales subject to Section 2.4(b), below, whether Compass is thereby exercising its Section 2.4(b) Drag Along Rights. The Disposition Notice shall be deemed effective with respect to each such Stockholder in accordance with Section 7.2.

          (b) Drag Along Rights. In the event that the Proposed Sale is a bona fide sale or other bona fide transfer for value to a non-affiliated third party (a “Third Party Purchaser”), Compass shall have the right to require each of the other Stockholders to sell, and each of the Stockholders hereby agrees to sell, an equal percentage of his Shares (the “Drag Along Right”) to such Third Party Purchaser on the same terms and conditions, and at the same time as, the Proposed Sale. If Compass has by way of the Disposition Notice exercised its Drag Along Rights, then, promptly upon receipt of such Disposition Notice, each Stockholder (each a “Drag Along Stockholder”) shall deliver to Compass (or such other person as may be agreed upon

between Compass and each such Drag Along Stockholder) to be held by Compass (or such other agreed upon person) in escrow for sale or return upon the terms of this Section 2.4, the certificate or certificates representing the Shares to be sold pursuant to this Section 2.4(b), duly endorsed or accompanied by executed stock powers, together with a limited power-of-attorney authorizing Compass to sell such Shares in accordance with the terms of this Section 2.4(b). To the fullest extent of the law, the Stockholders and any Additional Holders expressly waive any appraisal rights conferred under the Delaware General Corporation Law.

          (c) Tag Along Rights. Upon receipt of any Disposition Notice from Compass, each of the other Stockholders shall have, as a condition to closing the Proposed Sale, the right to require (the “Tag Along Right”) that the same percentage of his or its Shares be sold as part of, and upon the same terms and conditions as, the Proposed Sale. The rights referred to in this Section 2.4(c) shall be exercised by written notice to Compass (the “Tag Along Notice”). The Tag Along Notice shall only be deemed effective if received by Compass from the electing Stockholder (each a “Tag Along Stockholder”) within the period ending 30 days after the Disposition Notice was received by such Tag Along Stockholder. Promptly upon giving the Tag Along Notice, each Tag Along Stockholder shall deliver to Compass (or such other person as may be agreed upon between Compass and such Tag Along Stockholder) to be held by Compass (or such other person) in escrow for sale or return upon the terms of this Section 2.4(c), the certificate or certificates representing his Shares to be sold as part of the Proposed Sale, duly endorsed or accompanied by executed stock powers, together with a limited power-of-attorney authorizing Compass to sell such Shares in accordance with the terms of this Section 2.4.

          (d) Promptly upon the consummation of any Proposed Sale, and, in any event not later than 5 days after such consummation, Compass shall deliver to each Drag Along Stockholder or Tag Along Stockholder, as the case may be, the total sale price of his or its Shares sold as part of the Proposed Sale (after deduction of his proportionate share, based on number of Shares sold, of the reasonable out-of-pocket expenses associated with such Proposed Sale), together with evidence of the expenses associated with, and the completion and time of completion of, such Proposed Sale.

          (e) Notwithstanding anything herein to the contrary, Compass shall have 90 days from the date of receipt of any Disposition Notice during which to consummate the Proposed Sale to which such Disposition Notice relates. If, at the end of such 90 day period, Compass has not consummated the Proposed Sale, all certificates representing Shares delivered by either a Drag Along Stockholder or Tag Along Stockholder, as the case may be, to Compass for sale or other disposition as part of such Proposed Sale shall be returned to such Drag Along Stockholder or Tag Along Stockholder, as the case may be, and the transaction contemplated by the Proposed Sale shall be deemed to be a new Proposed Sale and shall again be subject to the provisions of this Section 2.4.

          (f) Limitations.

          (i) Notwithstanding anything herein to the contrary, in the event that all of the Stockholders are required to provide any indemnities in connection with the Proposed Sale, each Stockholder shall not be liable for more than such Person’s pro rata share (based upon the amount of consideration received) of any liability for indemnity, and such liability shall not exceed (A) the total purchase price or consideration received by such Stockholder for such Person’s Shares in the Proposed Sale plus (B) such Stockholders’ pro rata share of any escrow established in connection with any such Proposed Sale.

          (ii) Notwithstanding anything herein to the contrary, the Institutional Investors shall only be obligated to make representations or warranties in any such Proposed Sale as to such Person’s (i) title and ownership of the Shares to be sold by such Person, including the absence of liens or encumbrances on such Shares, (ii) authorization, execution and delivery of the relevant documents by such Person, and (iii) the enforceability of the relevant documents against such Person.

          2.5. Expiration of Restrictions. All restrictions imposed pursuant to this Section 2 shall terminate:

          (a) at any time upon the written agreement of the Company and all the Stockholders then signatory to this Agreement as it may be amended or revised from time to time;

          (b) immediately upon the dissolution of the Company or the bankruptcy or insolvency of the Company;

          (c) immediately upon the closing of the first underwritten offering by the Company to the public pursuant to an effective registration statement under the Securities Act; provided that such registration statement covers the offer and sale of Common Stock of which the aggregate net proceeds attributable to sales for the account of the Company exceed $50,000,000; provided, further, that the Stockholders shall be required to enter into customary lock-up agreements in such form as is generally required from company insiders by the lead underwriter in such offering; or

          (d) upon the acquisition by merger of the Company by an existing publicly traded company; provided that the Stockholders receive cash or publicly-tradeable securities in exchange for their Shares pursuant to such acquisition.

     Section 3. Pre-Emptive Rights.

          3.1. Rights to Purchase Additional Securities. So long as the restrictions imposed by Section 2 apply to the Stockholders and have not terminated pursuant to Section 2.5, except for Excluded Issuances (as defined in Section 3.3 below), if the Company authorizes or issues to any Person (the “Proposed Purchaser”) any of its Shares or other equity securities, debt securities containing equity features or other securities or other rights convertible into or

containing options or rights to acquire any such debt or equity securities (collectively, “Securities”), the Company shall, within 90 days of such authorization or issuance, offer to sell by written notice (the “Offer Notice”) to each holder of record of Shares on the date of such authorization or issuance a portion of such Securities equal to the number of Securities to be so issued multiplied by the quotient determined by dividing (A) the number of Shares held by such holder of Shares by (B) the number of Shares then outstanding (calculated assuming that all convertible securities shall be converted into Shares, to the extent then exercisable, immediately prior to such issuance). The Offer Notice shall describe the terms of the offering, including, without limitation, the Securities offered and the price and other terms of sale, and shall set forth in reasonable detail the payment terms and such Stockholder’s percentage allotment.

          3.2. Notice of Acceptance. In order to exercise his or its preemptive rights hereunder, each holder of Shares must deliver a written notice to the Company within 15 days of receipt of the Offer Notice, describing his or its election to purchase the Securities. If a holder of Shares fails to timely exercise such holder’s rights pursuant to this Section, the Company shall be entitled to sell such Securities which any holder of Shares has not elected to purchase to the Proposed Purchaser following such expiration on terms and conditions no more favorable to the Proposed Purchaser thereof than those offered to the holders of Shares.

          3.3. Excluded Issuances. “Excluded Issuances” means any Shares or any security exercisable, convertible or exchangeable for Shares that may be issued or sold (i) pursuant to stock options or restricted stock or similar arrangements issued or provided to managers, consultants, directors and/or key employees of the Company (up to twenty percent (20%) of the Company’s total outstanding share capital), (ii) other than for cash or cash equivalents as part of an arms’ length transaction in which the Company is acquiring control of an unaffiliated third-party from a person to whom such Shares are issued, (iii) pursuant to a public offering of the Company’s securities, or (iv) to institutional lenders lending money to the Company (but no more than a cumulative aggregate of five percent (5%) of the Company’s total outstanding share capital).

     Section 4. Legend on Certificates. Each certificate representing Shares shall (unless otherwise permitted by the provisions of this Agreement be stamped or otherwise imprinted with a legend (in addition to any legends as may be required pursuant to applicable state securities laws) substantially similar to the following:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED BY A HOLDER UNLESS AND UNTIL THE SECURITIES ARE REGISTERED UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION IS AVAILABLE AND, IF REQUIRED BY THE COMPANY, THE HOLDER HAS DELIVERED TO THE COMPANY AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

THIS CERTIFICATE AND THE SECURITIES REPRESENTED BY THIS CERTIFICATE AND ALL RIGHTS HEREIN ARE SUBJECT TO AND TRANSFERABLE (INCLUDING WITHOUT LIMITATION BY WAY OF PLEDGE OR OTHER GRANT OF A SECURITY INTEREST THEREIN) ONLY IN ACCORDANCE WITH THE PROVISIONS OF THAT CERTAIN STOCKHOLDERS’ AGREEMENT, DATED AS OF SEPTEMBER 20, 2005 AMONG THE COMPANY’S STOCKHOLDERS. A COPY OF SUCH STOCKHOLDERS’ AGREEMENT, AS MAY BE AMENDED FROM TIME TO TIME, IS ON FILE AND AVAILABLE FOR INSPECTION AT THE PRINCIPAL OFFICE OF THE COMPANY. ANY SALE, PLEDGE, GIFT, BEQUEST, TRANSFER, ASSIGNMENT, ENCUMBRANCE OR OTHER DISPOSITION OF THIS CERTIFICATE AND THE SECURITIES REPRESENTED HEREBY IN VIOLATION OF SAID STOCKHOLDERS’ AGREEMENT SHALL BE INVALID.

     Section 5. Covenant Not To Compete.

          5.1. During the period (the “Non-Compete Period”) beginning on the date hereof and ending on the second anniversary of the closing date of the Disposition or, if an Employment Termination shall occur prior to the Disposition, the date that is the later to occur of (i) the one year anniversary of the Employment Termination and (ii) the end of the period during which any severance payments are paid under any employment agreement with the Company in connection with such Employment Termination, each Management Stockholder and each Additional Holder that is an employee, officer or director of the Company agrees and covenants that, in connection with the sale, assignment, conveyance, transfer, encumbrance or other disposition of all the Shares owned by such Management Stockholder or Additional Holder (the “Disposition”) or, if such Management Stockholder or Additional Holder is an officer or employee of the Company or its subsidiaries, such individual’s termination of employment with the Company or its subsidiaries, as applicable (the “Employment Termination”), he or she:

          (a) shall not own, manage, operate, join, control or participate in the ownership, management, operation or control of, or be connected as a stockholder, member, manager, director, officer, employee, partner, consultant with, any for profit business, firm, entity or organization, which competes with the Company and its subsidiaries in the manufacturing, marketing and selling of printed circuit boards (the “Business”) in any state in the United States or anywhere else in the world (each a “Competing Concern”); provided, however, the forgoing shall not prohibit such holder from beneficially owning up to five percent (5%) of the outstanding equity securities of a for profit business, firm, entity or organization the equity securities of which are traded on a national securities exchange, the Nasdaq Stock market, or the London Stock Exchange. Each such Stockholder expressly acknowledges and agrees that such restriction is reasonable with respect to subject matter. Each such Stockholder expressly acknowledges and agrees that because the Company and its subsidiaries do business throughout the world, such restriction is reasonable as to geographic area. Each such Stockholder expressly acknowledges and agrees that because the Company is likely to continue to conduct a like business during the Non-Compete Period, such restriction is reasonable as to time.

          (b) shall not, during the period beginning on the closing date of the Disposition and ending on the second anniversary thereof, directly or indirectly,

          (i) contact, approach or solicit for the purpose of offering employment to or hiring (whether as an employee, consultant, agent, independent contractor or otherwise) or actually hire any person employed by the Company or any of its subsidiaries at any time prior to the closing date of the disposition or during the Non-Compete Period, without the prior written consent of Compass;

          (ii) solicit or attempt to induce any customer or other business relation of the Company or any of its subsidiaries into any business relationship (including the termination or rescission of the relationship) which might materially harm the Company or any related, affiliated or subsidiary organization of Company; or

          (iii) participate or concur in any remarks or actions that are disparaging or detrimental in any way to the business or personal reputation of the Company and any related, affiliated or subsidiary organization of Company, or any directors, officers, employees or representatives thereof.

          5.2. Whenever possible each provision and term of this Section 5 will be interpreted in a manner to be effective and valid but if any provision or term of this Section 5 is held to be prohibited or invalid, then such provision or term will be ineffective only to the extent of such prohibition or invalidity, without invalidating or affecting in any manner whatsoever the remainder of such provision or term or the remaining provisions or terms of this Section 5. If any of the covenants set forth in this Section 5 are held to be unreasonable, arbitrary or against public policy, such covenants will be considered divisible with respect to scope, time and geographic area, and in such lesser scope, time and geographic area, will be effective, binding and enforceable against each Seller.

     Section 6. Custody of Shares by Company.

          To facilitate the enforcement of the rights and obligations agreed to herein by the parties, each Stockholder and each Additional Holder, other than the Institutional Investors, acknowledges such rights and obligations and agrees that the Company or its designee shall hold each such Stockholder’s and Additional Holder’s Shares (other than the Institutional Investors’ shares), for the benefit of such Stockholder, subject to any rights granted to another party as permitted herein. Each Stockholder and Additional Holder (other than the Institutional Investors) shall promptly deliver to the Company all stock certificates evidencing the Shares of such holder, together with a stock power executed in blank in a form acceptable to the Company and its counsel. So long as the Company shall hold the Shares on behalf of a Stockholder, the Stockholder shall be entitled to exercise such holder’s right to vote such Shares and shall be entitled to receive any dividend (ordinary or extraordinary, whether paid in cash or property) or other distribution with respect to such Shares.

     Section 7. Miscellaneous.

          7.1. Effectiveness of Transfers. No Shares shall be transferred on the Company’s books and records, and transfers of Shares shall be otherwise ineffective, unless any such transfer is made pursuant to and in accordance with the terms and conditions of this Agreement.
