(a)Subject to Section 6(b), if the number of Directors that the Stockholders have the right to designate to the Board is decreased pursuant to Section 1(b), 1(c), 1(d) or 1(e) (each such occurrence, a “Decrease in Designation Rights”), then:

Section 5.Certain Covenants of the Corporation and the Stockholders.
(a)The Corporation agrees to take all Necessary Action to cause (i) the Board to be comprised of at least that number of Directors contemplated by Section 1(a) from time to time, or such other number of Directors as the Board may determine, subject to the terms of this Agreement, the Charter or the Bylaws of the Corporation; (ii) the individuals designated in accordance with Section 1 to be included in the slate of nominees to be elected to the Board at the next annual or special meeting of stockholders of the Corporation at which Directors are to be elected, in accordance with the Bylaws, Charter and General Corporation Law of the State of Delaware and at each annual meeting of stockholders of the Corporation thereafter at which such Director’s term expires; (iii) the individuals designated in accordance with Section 2(c) to fill the applicable vacancies on the Board, in accordance with the Bylaws, Charter, Securities Laws, General Corporation Law of the State of Delaware and the NASDAQ rules; and (iv) to adhere to, implement and enforce the provisions set forth in Section 4.
(b)The Stockholders shall comply with the requirements of the Charter and Bylaws when designating and nominating individuals as Directors, in each case, to the extent such requirements are applicable to Directors generally. Notwithstanding anything to the contrary set forth herein, in the event that the Board determines, within sixty (60) days after compliance with the first sentence of this Section 5(b), in good faith, after consultation with outside legal counsel, that its nomination, appointment or election of a particular Director designated in accordance with Section 1 or Section 2, as applicable, would constitute a breach of its fiduciary duties to the Corporation’s stockholders or does not otherwise comply with any requirements of the Charter or Bylaws, then the Board shall inform the Stockholders of such determination in writing and explain in reasonable detail the basis for such determination and shall, to the fullest extent permitted by law, nominate, appoint or elect another individual designated for nomination, election or appointment to the Board by the Stockholders (subject in each case to this Section 5(b)). The Board and the Corporation shall, to the fullest extent permitted by law, take all Necessary Action required by this Section 5 with respect to the election of such substitute designees to the Board.
(c)In the event the Board recommends that its stockholders vote in favor of any matter that the Board has determined in good faith (after reasonable consultation with such Persons as the Board deems appropriate (including the Corporation’s or the Board’s legal and financial advisors, as applicable), and following any deliberations of the Board that the Board determines are necessary or appropriate to consider the matter) to be advisable and in the best interests of its stockholders, then, if requested by OEP, Sanken hereby agrees to vote all outstanding shares of Common Stock held thereby (i) in favor of such matter and any other matter that the Board has determined is necessary or appropriate in connection with such matter and (ii) against and in opposition to any matter that would reasonably be expected to oppose, impede, frustrate, prevent or nullify such matter.  The Stockholders acknowledge that Sanken has agreed to the matters in the foregoing sentence in order to protect OEP’s rights as a minority stockholder of the 
5






Corporation, and in consideration therefor, OEP agrees that, at the reasonable request of Sanken, it will use good faith efforts to be generally supportive of the Corporation’s proposed strategic direction unless OEP determines (in its good faith discretion) that such proposed strategic direction would reasonably be expected to materially and adversely affect the Corporation or OEP.  For the avoidance of doubt, this Section 5(c), is an agreement as between the Stockholders and a covenant only of the Stockholders and not of the Corporation, and the Corporation shall have no rights or obligations under this Section 5(c).
(d)In the event that either Stockholder desires to sell a portion of its shares of Common Stock on the open market which is greater than two percent (2%) of all of the then-issued and outstanding shares of Common Stock to any other Person(s), it shall, subject to any applicable confidentiality restrictions imposed on such Stockholder by law, contract or otherwise, use commercially reasonable efforts to discuss any such possible sale with the other Stockholder, so that the Stockholders can consider in good faith any potential commercial or other matters that may result from such potential sale; provided, however, that in no event shall the foregoing provide any Stockholder with a consent, approval or other right in respect of any sale of, or transaction involving, the other Stockholder’s shares of Common Stock.  In addition, in no event shall either Stockholder directly sell a portion of its shares of Common Stock which is greater than ten percent (10%) of all of the then-issued and outstanding shares of Common Stock to any other Person that is a material competitor of the Corporation or a material competitor of the other Stockholder without the prior written consent of the other Stockholder (which consent shall not be unreasonably withheld, conditioned or delayed); provided, that, for the avoidance of doubt, the foregoing restriction shall only apply to a direct sale of shares of Common Stock from a Stockholder to any such material competitor in a privately negotiated transaction solely between such Stockholder and such material competitor, and shall not apply to any other transaction, including any underwriter-led or other secondary sale or offering, block trade, open market sale, tender offer, merger or sale of the Corporation or other similar transactions.  Notwithstanding anything to contrary contained herein, in no event shall this Section 5(d) operate to restrain, limit or supersede the agreements of the Stockholders in Section 5(c), and in all events this Section 5(d) shall be subordinate to the provisions of Section 5(c). For the avoidance of doubt, this Section 5(d) is an agreement as between the Stockholders and a covenant only of the Stockholders and not of the Corporation, and the Corporation shall have no rights or obligations under this Section 5(d).
Section 6.Termination. 
(a)This Agreement shall terminate upon the earliest to occur of any one of the following events:
(i)both (i) Sanken and its Affiliates and (ii) OEP and its Affiliates ceasing to own any shares of Common Stock; and
(ii)the unanimous written consent of the parties hereto.
For the avoidance of doubt, the rights and obligations (i) of Sanken under this Agreement shall terminate upon Sanken and its Affiliates ceasing to own any shares of Common Stock and (ii) subject to Section 6(b), of OEP under this Agreement shall terminate upon OEP and its Affiliates ceasing to own any shares of Common Stock. Notwithstanding the foregoing, nothing in this Agreement shall modify, limit or otherwise affect, in any way, any and all rights to indemnification, exculpation and/or contribution owed by any of the parties hereto, to the extent arising out of or relating to events occurring prior to the date of termination of this Agreement or the date the rights and obligations of such party under this Agreement terminates in accordance with this Section 6. 
6






(b)Notwithstanding anything herein to the contrary, (a) in the event that OEP ceases to be entitled to any particular right or benefit hereunder because OEP and its Affiliates collectively cease to beneficially own, directly or indirectly, in the aggregate at least five percent (5%) or more of all issued and outstanding shares of Common Stock (including any rights contained in Sections 1, 2, 3 and 4 hereof), then any such right or benefit shall automatically become a right or benefit of the Nominating and Corporate Governance Committee for so long as this Agreement remains in effect, and the Nominating and Corporate Governance Committee shall have the right to enforce any such rights or benefits mutatis mutandis as though it were OEP under any applicable provision (but without regard to any share ownership requirements set forth therein), and accordingly all of Sanken’s and the Company’s obligations in respect of any such provisions shall remain in full force and effect, and (b) in the event that the other rights and obligations of OEP and its Affiliates contained herein terminate as to OEP and such Affiliates pursuant to Section 6(a) above because OEP and its Affiliates cease to own any shares of Common Stock, this Agreement shall remain in effect (unless otherwise terminated pursuant to another clause of Section 6(a)), and all such other rights and obligations of OEP and its Affiliates shall automatically become a right or obligation of the Nominating and Corporate Governance Committee for so long as this Agreement remains in effect, and the Nominating and Corporate Governance Committee shall have the right to enforce any such rights mutatis mutandis as though it were OEP under any applicable provision, and accordingly all of Sanken’s and the Company’s obligations in respect of any such provisions shall remain in full force and effect.  In addition, from and after such time as OEP and its Affiliates collectively cease to beneficially own, directly or indirectly, in the aggregate at least five percent (5%) or more of all issued and outstanding shares of Common Stock clause (ii) of the proviso set forth in Section 2(b) and clauses (ii) and (iii) of the proviso set forth in Section 2(c) shall, in each case, cease to be operative under any and all circumstances and as a result, Sanken shall cease to have any rights set forth in such clauses from and after such time. 
Section 7.Information Rights.  The Corporation will furnish to each Stockholder owning at least five percent (5%) of all issued and outstanding shares of Common Stock the following information:
(a)As soon as available, but no later than the later of (i) ninety (90) days following completion of each fiscal year and (ii) the applicable filing deadline under SEC rules, the audited consolidated balance sheet of the Corporation and its Subsidiaries as at the end of each such fiscal year and the audited consolidated statements of income, cash flows and changes in stockholders' equity for such year of the Corporation and its Subsidiaries, setting forth in each case in comparative form the figures for the next preceding fiscal year, accompanied by the report of independent certified public accountants of recognized national standing; provided that this requirement shall be deemed to have been satisfied if, on or prior to such date, the Corporation files its annual report on Form 10-K for the applicable fiscal year with the SEC;

provided, that, in each case, the Corporation shall not be obligated to provide such access or materials if the Corporation determines, in its reasonable judgment, that doing so would reasonably be expected to (i) result in the disclosure of trade secrets or competitively sensitive information to third parties, (ii) violate applicable law or any contractual or other obligation of confidentiality owing to a third party, (iii) jeopardize the protection of an attorney-client privilege, attorney work product protection or other legal privilege (provided, however, that the Corporation shall use reasonable efforts to provide alternative, redacted or substitute documents or information in a manner that would not result in the loss of the ability to assert attorney-client privilege, attorney work product protection or other legal privileges), or (iv) expose the Corporation to risk of liability for disclosure of personal information.  In furtherance of the foregoing, each Stockholder agrees that it shall not (and shall cause its Subsidiaries not to) use or disclose any information or materials received pursuant to this Section 7 (or otherwise received from or in respect of the Corporation or its Subsidiaries or which is otherwise related to the Corporation’s or its Subsidiaries’ business) in a manner that would reasonably be expected to be adverse to the Corporation or its Subsidiaries or their respective businesses, except that the foregoing shall not in any way limit, restrict or supersede in any respect any waiver of corporate opportunity doctrine or similar provision in favor of any Stockholder in any of the Corporation’s Governing Documents (including the Charter) (and in the event of any conflict between any such provision and this sentence with respect to any Stockholder, such provision shall control).
Section 8.Public Announcements.  Subject to each Stockholder’s disclosure obligations imposed by law or regulation or the rules of any stock exchange upon which its securities are listed, each of the parties hereto will cooperate with each other in the development and distribution of all news releases and other public information disclosures with respect to the Corporation and/or its Subsidiaries, and no Stockholder will make any such news release or public disclosure without first consulting with the other Stockholder hereto, and, in each case, also receiving the consent of such Stockholder (which shall not be unreasonably withheld or delayed) and each Stockholder shall coordinate with the party whose consent is required with respect to any such news release or public disclosure.  Notwithstanding the foregoing, this Section 8 shall not apply to any press release or other public statement made by a Stockholder (a) which is consistent with prior disclosure and does not contain any information that has not been previously announced or made public in accordance with the terms of this Agreement or (b) is made to its auditors, attorneys, accountants, financial advisors or limited partners (who, in the case of this clause (b), are bound by customary duties of confidentiality).
