ARTICLE II

CORPORATE GOVERNANCE

Section 2.1   Board of Directors Representation.  (a)    Effective as of the date hereof, the Stockholders and the Company shall use their reasonable best efforts to cause the Board of Directors to be comprised of nine directors of whom:

(i)                                 three shall be designated by POI Acquisition (the “Acquisition Designees”);

(ii)                              two shall be designated by QDRF (the “QDRF Designees”);

(iii)                           two shall be designated pursuant to the Merger Agreement for a period of not less than two years from the date hereof;

(iv)                          one shall be Richard Ginsburg, president and chief executive officer of the Company; and

(iv)                              one shall be an Independent Person selected by a majority of the other directors, which person shall initially be Robert J. McGuire.

(b)   At such time as POI Acquisition shall cease to own Common Shares in an amount equal to at least 25% of the Common Shares issued and outstanding as of the effective date hereof, POI Acquisition shall have the right to designate two Acquisition Designees rather than three Acquisition Designees pursuant to Section 2.1(a) above. At such time as POI Acquisition shall cease to own Common Shares in an amount equal to at least 15% of the Common Shares issued and outstanding as of the effective date hereof, POI Acquisition shall have the right to designate one Acquisition Designee rather than two Acquisition Designees pursuant to Section 2.1(a) above. At such time as POI Acquisition shall cease to own Common Shares in an amount equal to at least 10% of the Common Shares issued and outstanding as of the effective date hereof, POI Acquisition shall cease to have the right to designate a director to the Board of Directors pursuant to Section 2.1(a) above. Upon each of the triggering events set forth in this Section 2.1(b) above, POI Acquisition shall promptly cause one of its Acquisition Designees to resign from the Board of Directors and all committees thereof. Upon any such resignation, the Stockholders will use their reasonable best efforts to cause the directors

4

remaining in office to either decrease the size of the Board of Directors to eliminate such vacancy or cause the vacancy created thereby to be filled by a designee selected by a majority of the directors remaining in office.

(c)   At such time as QDRF shall cease to own Common Shares in an amount equal to at least 15% of the Common Shares issued and outstanding as of the effective date hereof, QDRF shall have the right to designate one QDRF Designee to the Board of Directors rather than two QDRF Designees pursuant to Section 2.1(a) above. At such time as QDRF shall cease to own Common Shares in an amount equal to at least 10% of the Common Shares issued and outstanding as of the effective date hereof, QDRF shall cease to have the right to designate a director to the Board of Directors pursuant to Section 2.1(a) above. Upon each of the triggering events set forth in this Section 2.1(c) above, QDRF shall promptly cause one of its QDRF Designees to resign from the Board of Directors and all committees thereof. Upon any such resignation, the Stockholders will use their reasonable best efforts to cause the directors remaining in office to either decrease the size of the Board of Directors to eliminate such vacancy or cause the vacancy created thereby to be filled by a designee selected by a majority of the directors remaining in office.

(d)   At such time as Mr. Ginsburg ceases to be the chief executive officer of the Company, he shall no longer be entitled to serve as a director pursuant to Section 2.1(a) above.  Upon any such resignation, the Stockholders will use their reasonable best efforts to cause the directors remaining in office to either decrease the size of the Board of Directors to eliminate such vacancy or cause the vacancy created thereby to be filled by a designee selected by a majority of the directors remaining in office.

(e)   Each Stockholder agrees to vote, or act by written consent with respect to, any Common Shares owned directly or indirectly by it, at each annual or special meeting of stockholders of the Company at which directors are to be elected or to take all actions by written consent in lieu of any such meeting as are necessary, and the Company shall use its reasonable best efforts to take all appropriate actions as are necessary, to cause the Board of Directors to be comprised of the number and type of directors specified in Section 2.1(a). In conjunction with a Trigger Event and effective immediately prior to the consummation thereof, the Stockholders and the Company shall take all action necessary and appropriate to reconstitute the size and composition of the Board of Directors in accordance with the listing rules of the applicable securities exchange; provided, however, that in the case of any such reconstitution of the Board of Directors, POI Acquisition shall remain entitled pursuant to Section 2.1(a) to designate the Acquisition Designees (subject to Section 2.1(b)), QDRF shall remain entitled to designate the QDRF Designee (subject to Section 2.1(c)), Mr. Ginsburg shall remain entitled to serve as a director (subject to Section 2.1(d)) and the Company shall continue to perform its obligations under the Merger Agreement with respect to directors designated thereunder.

(f)   Until such time as POI Acquisition ceases to own Common Shares in an amount equal to at least 40% of the Common Shares issued and outstanding as of the effective date hereof, POI Acquisition shall have the right, exercisable at any time upon delivery of written notice to QDRF and the Company, to elect to cause the Board of Directors to be increased to include two additional directors and to designate such directors, and shall similarly have the right to designate one additional director to the extent that POI Acquisition owns

5

Common Shares in an amount equal to at least 35% (but less than 40%) of the Common Shares issued and outstanding as of the effective date hereof (the “Acquisition Election”). Upon making the Acquisition Election, the Stockholders (and their respective Stockholder Designees) and the Company shall use their reasonable best efforts to take all appropriate action to cause the size of the Board of Directors to be increased to include the director(s) designated by POI Acquisition. Upon making the Acquisition Election, (i) the number of Acquisition Designees set forth in Section 2.1(a)(i) shall be increased by the number of Acquisition Designees so designated and (ii) at such time as POI Acquisition shall cease to own the requisite percentage of Common Shares issued and outstanding to designate one or more directors pursuant to this Section 2.1(f), POI Acquisition shall promptly cause such Acquisition Designee(s) to resign from the Board of Directors and all committees thereof. Upon any such resignation, the Stockholders will use their reasonable best efforts to cause the directors remaining in office to either decrease the size of the Board of Directors to eliminate such vacancy or cause the vacancy created thereby to be filled by a designee selected by a majority of the directors remaining in office.

(g)   If any Stockholder entitled to designate directors hereunder requests in writing that any of its designees be removed as a director, the other Stockholder shall vote, or act by written consent with respect to, all Common Shares owned directly or indirectly by such other Stockholder and otherwise take or cause to be taken all actions necessary to remove such director designated by such Stockholder. Unless a Stockholder shall otherwise request in writing, no other Stockholder shall take any action to cause the removal of any directors designated by such Stockholder. In the event that a vacancy is created at any time by the death, disability, retirement, resignation or removal (with or without cause) of any director designated by a Stockholder, so long as such Stockholder has the right to designate a replacement designee at such time, the Company and the other Stockholder shall use their reasonable best efforts to take all appropriate action necessary to cause the vacancy created thereby to be filled by the replacement designated by such Stockholder.

(h)   POI Acquisition and QDRF each shall be entitled to designate an employee, director or officer of such entity or its Affiliates to serve as a nonvoting observer to the Board of Directors (an “Observer”) at any time that such entity owns at least 5% of the outstanding Common Shares. The Observer shall be permitted to attend all meetings of the Board of Directors. The Company shall provide the Observer, in the same manner as provided to directors, notice of such meetings and copies of all materials, financial or otherwise, which the Company provides to its directors; provided, however, that the Company may exclude the Observer from access to any materials or from any meeting, or any portion of the foregoing, if the Company reasonably believes upon advice of counsel that such exclusion is reasonably necessary to preserve the attorney-client privilege, to protect confidential or proprietary information or for other similar reasons.

(i)   The parties hereto acknowledge and agree that designation of a director as a Stockholder Designee does not in itself preclude such director from being deemed “independent” for purposes of applicable rules and regulations of the United States Securities and Exchange Commission or the securities exchange upon which the Common Shares are listed (each such qualifying director, an “Independent Designee”).

6

(j)   For purposes of this Agreement, a Stockholder shall be deemed to own its proportional interest of any Common Shares held by a Person beneficially owned by such Stockholder (determined based on such Stockholder’s pro rata direct or indirect equity interest in such Person).

(k)   The Company shall reimburse each Stockholder Designee and each Observer for their reasonable out-of-pocket expenses incurred by them for the purpose of attending meetings of the Board of Directors, the board of directors of any Subsidiary of the Company or the respective committees thereof.

Section 2.2   Bylaws.   (a)    At the first meeting of the Board of Directors following the date of this Agreement, the bylaws of the Company shall be amended to provide that (i) until such time as POI Acquisition ceases to own Common Shares in an amount equal to at least 20% of the Common Shares issued and outstanding as of the effective date hereof, at least one of the Acquisition Designees (other than an Independent Designee) shall be required to be present to constitute a quorum of the Board of Directors and (ii) until such time as QDRF ceases to own Common Shares in an amount equal to at least 20% of the Common Shares issued and outstanding as of the effective date hereof, at least one of the QDRF Designees (other than an Independent Designee) shall be required to be present to constitute a quorum of the Board of Directors; provided, however, that (x) any of the Stockholders may waive such right for any given meeting of the Board of Directors and (y) none of the Stockholders may use such provision in bad faith to avoid the taking of any action by the Board of Directors.

(b)   If and for so long as POI Acquisition has the rights described in Section 2.2(a)(i) above neither the Company nor any other Stockholder shall, without the prior written consent of POI Acquisition, take any action to amend the bylaws of the Company in any manner that would impair POI Acquisition’s rights hereunder.  If and for so long as QDRF has the rights described in Section 2.2(a)(ii) above neither the Company nor any other Stockholder shall, without the prior written consent of QDRF, take any action to amend the bylaws of the Company in any manner that would impair QDRF’s rights hereunder.

Section 2.3.   Information and Inspection Rights.  The Company shall furnish to each Stockholder that, together with its Affiliates, owns at least 5% of the outstanding Common Shares such information regarding the business, affairs, prospects and financial condition of the Company and its Subsidiaries as such Stockholder may reasonably request and shall permit such Stockholder or any of its designated representatives to examine the books and records of the Company and its Subsidiaries (and to make copies thereof and extracts therefrom), and to inspect their respective facilities.

(b)   To the extent a Stockholder or Permitted Transferee described in clause (i) above is not an individual or an estate, and a Person (which is not a Permitted Transferee of the Stockholder or of such Permitted Transferee, as the case may be) acquires Control of such Stockholder or Permitted Transferee, (x) such acquisition of Control shall be deemed to be a transfer of the Common Shares held by such Stockholder or Permitted Transferee subject to the restrictions on transfer contained in this Agreement (including, without limitation, Articles III and IV hereof) and (y) to the extent such Stockholder or Permitted Transferee then holds assets in addition to Common Shares, the determination of the purchase price deemed to have been paid for the Common Shares held by such Permitted Transferee in such deemed transfer for purposes of the provisions of this Agreement shall be made by the Board of Directors in good faith.

Section 3.3   Notice of Proposed Transfer.  No fewer than 10 days prior to any proposed transfer of any Common Shares by a Stockholder (other than under the circumstances described in Article IV or pursuant to a Registered Sale or a Rule 144 Sale), the Stockholder shall give written notice to the Company and the other Stockholder of its intention to effect such transfer. Each such notice shall describe the manner of the proposed transfer, the proposed date of the transfer and the number of Common Shares proposed to be transferred and, if requested by the Company, shall be accompanied by an opinion of counsel reasonably satisfactory to the Company to the effect that the proposed transfer of the Common Shares may be affected without registration under the Securities Act.

Section 3.4   Validity of Transfers; Compliance with Laws, Agreement.  (a)  Any attempt to transfer any Common Shares in violation of this Agreement shall be null and void.  The Company shall not record on its stock transfer books or otherwise any transfer of Common Shares in violation of the terms and conditions set forth herein.

an agreement in form and substance reasonably acceptable to the Company) to become a party to this Agreement and shall have such rights and obligations of its transferor for purposes of Articles III and IV; provided, that a transferee of Common Shares pursuant to clause (i) of Section 3.2(a) shall have all of the rights and obligations of the transferor Stockholder;  provided, further, that, in connection with a transfer of at least 10% of the outstanding Common Shares by a Stockholder, such Stockholder may also assign its rights and obligations under Section 2.1 to such transferee, and in such circumstances, the transferee shall have the rights and obligations of the transferor Stockholder under such Section; provided, however, that such transferee shall not be entitled to designate a Stockholder Designee or an Observer unless such Stockholder Designee or Observer, as the case may be, is reasonably acceptable to the Board of Directors.

ARTICLE IV

RIGHT OF FIRST OFFER, TAG-ALONG SALE, DRAG-ALONG

Section 4.1.   Right of First Offer.  (a)    If QDRF (for purposes of this Section 4.1, a “Selling Stockholder”) proposes to transfer (unless the proposed transfer is a Permitted Transfer or a transfer pursuant to such Selling Stockholder’s “tag-along” rights under Section 4.2, in which case the following provisions need not be complied with) all or any portion of its Common Shares (the number of Common Shares proposed to be transferred by the Selling Stockholder, the “Subject Securities”), the Selling Stockholder shall deliver a notice of intention to sell (a “Sale Notice”) to POI Acquisition (the “Offeree Stockholder”) setting forth the number of Subject Securities proposed to be transferred, an irrevocable offer to sell such Subject Securities to the Offeree Stockholder and the terms and conditions pursuant to which the Selling Stockholder is offering to sell such Subject Securities.

(b)   Upon receipt of a Sale Notice, the Offeree Stockholder shall have the right to elect to purchase at the price and on the terms and conditions stated in the Sale Notice, all, but not less than all, of the Subject Securities (as allocated among the Offeree Stockholder in their discretion).  In the event that the Offeree Stockholder elects to purchase all of the Subject Securities, the Offeree Stockholder shall so notify the Selling Stockholder within 20 days (the “Option Period”) after the receipt by such party of the Sale Notice.  Any such election shall be made by written notice (a “Notice of Election”) to the Selling Stockholder.

(c)   If a Notice of Election with respect to the Subject Securities shall have been delivered to the Selling Stockholder, the Selling Stockholder shall sell such Subject Securities to the Offeree Stockholder designated in the Notice of Election at the price and on the terms and conditions stated in the Sale Notice.

(d)   The closing of the sale of Subject Securities to the Offeree Stockholder shall take place at the offices of the Company, or such other location as the parties to the sale may mutually select, on a date the parties may mutually select, no later than 30 days following the expiration of the Option Period (or upon the expiration of such longer period required to obtain any necessary regulatory approvals).  At such closing, the Selling Stockholder shall deliver a certificate or certificates for the Subject Securities to be sold, accompanied by stock powers with signatures guaranteed and all necessary stock transfer taxes paid and stamps affixed, if

9

necessary, against receipt of the purchase price therefor by certified or official bank check or by wire transfer of immediately available funds.

(e)   If the Offeree Stockholder (and/or its assignee(s)) does not elect to purchase all of the Subject Securities by the end of the Option Period, such Subject Securities may be sold to any Person for a period of 180 days following the expiration of the Option Period at a price not lower than the price specified in the Sale Notice and on other terms and conditions not more favorable to the purchaser than those specified in the Sale Notice. Any Subject Securities not sold by such 180th day shall again be subject to the restrictions contained in this Section 4.1.

(f)   The Offeree Stockholder shall be entitled to assign any or all of their rights under this Section 4.1 to any other Person.

Section 4.2.   Tag-Along Rights.  (a)    In the event that POI Acquisition (for purposes of this Section 4.2, a “Selling Stockholder”) proposes to transfer (other than by way of a Permitted Transfer) all or any portion of the Common Shares owned by such Selling Stockholder (any of the foregoing, a “Sale”), then unless such Selling Stockholder is entitled to give and does give a Drag-Along Notice pursuant to Section 4.3, such Selling Stockholder shall give notice (a “Notice of Intention to Sell”) to the other Stockholder (for purposes of this Section 4.2, the “Other Stockholder”) and the Company promptly, and in any event not more than 10 days after the execution and delivery by all the parties thereto of the definitive agreement relating to the Sale, setting forth in reasonable detail the terms and conditions of such proposed Sale, including the number of Common Shares proposed to be so transferred, the name of the third party purchaser, the proposed amount and form of consideration. In the event that the terms and/or conditions set forth in the Notice of Intention to Sell are thereafter amended in any respect, the Selling Stockholder shall give written notice (an “Amended Notice”) of the amended terms and conditions of the proposed Sale promptly to the other Stockholder and the Company.

(b)   The Other Stockholder shall have the right, exercisable upon written notice to the Selling Stockholder within 20 days after such Stockholder’s receipt of any Notice of Intention to Sell, or, if later, within 20 days of such Stockholder’s receipt of the most recent Amended Notice, to participate in the proposed Sale by the Selling Stockholder to the proposed purchaser on the terms and conditions set forth in such Notice of Intention to Sell or the most recent Amended Notice, as the case may be (such participation rights being hereinafter referred to as “tag-along” rights). Each Stockholder may participate with respect to the Common Shares owned by such Stockholder in an amount equal to the product obtained by multiplying (i) the aggregate number of Common Shares owned by such Stockholder by (ii) a fraction, the numerator of which is equal to the number of Common Shares proposed to be sold or transferred by the Selling Stockholder and the denominator of which is the aggregate number of Common Shares owned by the Selling Stockholder. If the Other Stockholder has not notified the Selling Stockholder of its intent to exercise tag-along rights 20 days after receipt of the Notice of Intention to Sell or, if later, within 20 days of receipt of an Amended Notice, the Other Stockholder shall be deemed to have elected not to exercise such tag-along rights with respect to the Sale contemplated by such Notice of Intention to Sell or such Amended Notice, as the case may be (in the case of an Amended Notice, regardless of its election pursuant to the Notice of Intention to Sell relating to such Sale).  If the number of Common Shares elected to be sold by the Selling Stockholder and the Other Stockholder, in addition to the number of Common Shares

10

elected to be sold by other stockholders of the Company (“Other Tagging Stockholders”) pursuant to similar tag-along rights as those contained in this Agreement, is greater than the number of Common Shares specified in the Notice of Intention to Sell, the number of Common Shares being sold by each such holder shall be reduced such that the applicable holder shall be entitled to (and obligated to) sell only its pro rata portion of Common Shares (based on the number of Common Shares owned by such holder to the total number of Common Shares owned by all of such electing holders).  If a Stockholder elects not to include the maximum number of Common Shares that such holder would have been permitted to include in a proposed Sale, the Selling Stockholder, the Other Stockholder and any Other Tagging Stockholders may sell in the proposed Sale a number of additional Common Shares owned by any of them equal to their pro rata portion of the number of Common Shares eligible to be included in the proposed Sale and not so elected to be included (based on the number of Common Shares owned by such holder to the total number of Common Shares owned by all of such electing holders).

(c)   If the Other Stockholder exercises its rights under this Section 4.2, the closing of the purchase of the Common Shares with respect to which such rights have been exercised will take place concurrently with the closing of the sale of the Selling Stockholder’s Common Shares to the purchaser.

(d)   In connection with any Sale pursuant to this Section 4.2, the Other Stockholder shall make to the purchaser in the Sale the same representations, warranties, covenants, indemnities and agreements as the Selling Stockholder makes in connection with the proposed Sale (except that in the case of representations, warranties, covenants, indemnities and agreements pertaining specifically to the Selling Stockholder, a Stockholder exercising its “tag-along” rights shall make the comparable representations, warranties, covenants, indemnities and agreements pertaining specifically to itself); provided, that all representations, warranties, covenants and indemnities shall be made by the Selling Stockholder, the Other Stockholder and the Other Tagging Stockholders severally and not jointly. Each Stockholder and any Other Tagging Stockholder participating in the Sale will be responsible for funding its proportionate share of any escrow arrangements in connection with the Sale and for its proportionate share of any withdrawals therefrom.  All fees, commissions, adjustments to purchase price, expenses and indemnities of the Selling Stockholder, the Other Stockholder and any Other Tagging Stockholders thereunder shall be borne by each of them on a pro rata basis based on the number of Common Shares sold by each of them in such Sale.

Section 4.3.   Drag-Along.  (a)    If (i) POI Acquisition (for purposes of this Section 4.3, the “Selling Stockholder”) receives a bona fide offer from any third party who is not an Affiliate of either the Company or POI Acquisition to purchase (including a purchase by merger, consolidation or similar transaction) 100% of the Common Shares owned by the Selling Stockholder at such time, (ii) at least 90% of the fair market value of the consideration to be received by the Selling Stockholder in such offer is in the form of cash, Cash Equivalents or Marketable Securities and (iii) such offer is accepted by the Selling Stockholder, then QDRF (for purposes of this Section 4.3, the “Other Stockholder”) hereby agrees that, if requested by the Selling Stockholder, it will transfer to such purchaser, subject to Section 4.3(b), on the terms of the offer so accepted by the Selling Stockholder, including time of payment, form of consideration and adjustments to purchase price, all of its Common Shares.

PREEMPTION

Section 5.1   Preemptive Rights.  (a)  Each Stockholder shall have the right to purchase for cash its Preemptive Right Pro Rata Share of newly issued (i) Common Shares or (ii) options or warrants to purchase, or securities convertible into or exchangeable for, Common Shares (“Rights” and together with Common Shares, “POI Securities”), in each case that the Company or any Subsidiary of the Company may from time to time propose to sell for cash.  A Stockholder’s “Preemptive Right Pro Rata Share” shall be, at any given time, that proportion, calculated prior to any proposed new issuance, which the number of Common Shares owned by such Stockholder at such time bears to the total number of Common Shares outstanding at such time.

(b)   In the event the Company proposes to undertake an issuance for cash of POI Securities to any Person, it shall give the Stockholders written notice (the “Preemptive Notice”) of its intention to sell POI Securities for cash, the price, the identity of the purchaser and the

principal terms upon which the Company proposes to issue the same.  Subject to Section 5.1(a), each Stockholder shall have ten Business Days from the delivery date of any Preemptive Notice to agree to purchase a number of POI Securities up to its Preemptive Right Pro Rata Share of POI Securities (in each case calculated prior to the issuance) for the price and upon the terms specified in the Preemptive Notice by giving written notice to the Company and stating therein the number of POI Securities to be purchased.

(c)   In the event that any Stockholder fails to purchase all of its Preemptive Right Pro Rata Share pursuant to this Section 5.1, the Company shall have 180 days after the date of the Preemptive Notice to consummate the sale of the POI Securities with respect to which such Stockholder’s preemptive right was not exercised, at or above the price and upon terms not more favorable to the purchasers of such POI Securities than the terms specified in the initial Preemptive Notice given in connection with such sale.

Section 5.2   Excluded Securities.  The parties hereby agree that the preemption rights described in Section 5.1 shall not be exercisable with respect to any issuance by the Company or any Subsidiary of the Company of the following securities (“Excluded Securities”):

(a)   any issuance of securities to officers, employees, directors or consultants of any Protection One Entity in connection with such person’s employment, consulting or director arrangements with a Protection One Entity;

(b)   any issuance of securities in connection with any business combination or acquisition transaction involving any Protection One Entity, including any issuance to the equityholders or management of the entity that is the subject of such business combination or acquisition transaction; or

(c)    any securities issued by the Company or a Subsidiary of the Company pursuant to a public offering registered with the SEC.
