Exhibit 10.43 Salary Continuation Agreement with Wilson Cheung AMENDED AND RESTATED SALARY CONTINUATION AGREEMENT This Amended and Restated Salary Continuation Agreement (the "Agreement") is made and entered into as of January 13, 1999 (the "Effective Date"), by and between Network Peripherals Inc., a Delaware corporation (the "Company"), and Wilson Cheung ("Employee"). Recitals The Company recognizes that the possibility of a Change in Control or other event may occur which may change the nature and structure of the Company and that uncertainty regarding the consequences of such events may adversely affect the Company's ability to retain its key employees. The Company also recognizes that the Employee possesses an intimate and essential knowledge of the Company upon which the Company may need to draw for objective advice and continued services in connection with any acquisition of the Company or other Change in Control that is potentially advantageous to the Company's stockholders. The Company believes that the existence of this Agreement will serve as an incentive to Employee to remain in the employ of the Company and will enhance its ability to call on and rely upon the Employee in connection with a Change in Control. The Company and the Employee desire to enter into this Agreement in order to provide additional compensation and benefits to the Employee in recognition of past services and to encourage Employee to continue to devote his full attention and dedication to the Company and to continue his employment with the Company. 1. Definitions. As used in this Agreement, unless the context requires a different meaning, the following terms shall have the meanings set forth herein: (a) "Cause" means: (i) theft, a material act of dishonesty, fraud, the falsification of any employment or Company records or the commission of any criminal act which impairs Employee's ability to perform his duties under this Agreement; (ii) improper disclosure of the Company's confidential, business or proprietary information by the Employee; (iii) any action by Employee which the Company's Board of Directors (the "Board") reasonably believes has had or will have a material detrimental effect on the Company's reputation or business; or 1 (iv) persistent failure of the Employee to perform the lawful duties and responsibilities assigned by the Company which is not cured within a reasonable time following the Employee's receipt of written notice of such failure from the Company. (b) "Change in Control " means an Ownership Change Event (as defined below) or a series of related Ownership Change Events (collectively, the "Transaction") wherein the stockholders of the Company immediately before the Transaction do not retain immediately after the Transaction, in substantially the same proportions as their ownership of shares of the Company's voting stock immediately before the Transaction, direct or indirect beneficial ownership of more than fifty percent (50%) of the total combined voting power of the outstanding voting stock of the Company or the corporation or corporations to which the assets of the Company were transferred (the "Transferee Corporation(s)"), as the case may be. For purposes of the preceding sentence, indirect beneficial ownership shall include, without limitation, an interest resulting from ownership of the voting stock of one or more corporations which, as a result of the Transaction, own the Company or the Transferee Corporation(s), as the case may be, either directly or through one or more subsidiary corporations.

(d) "Effective Date" means the day and year first set forth above.

In addition, Employee shall be entitled to the benefits afforded to other employees similarly situated under the Company's vacation, holiday and business expense reimbursement policies, as amended from time to time.

This Subsection 4(a)(v) shall apply to all such stock option agreements, whether heretofore or hereafter entered into between the Company and the Employee. (b) The Employee's entitlement to any benefits under Section 4 is conditioned upon the Employee's execution and delivery to the Company of (i) a general release of claims in a form satisfactory to the Company and (ii) a resignation from all of Employee's positions with the Company (with the exception of any continued employment for the purposes set forth in Section 4(a)) in a form satisfactory to the Company. (c) In the event that Employee accepts employment with, or provides any services to (whether as a partner, consultant, joint venturer or otherwise), any person or entity 5 which offers products or services that are competitive with any products or services offered by the Company or with any products or services that Employee is aware the Company intends to offer, Employee shall be deemed to have resigned from his employment with the Company effective immediately upon such acceptance of employment or provision of services. Upon such resignation, Employee shall not be entitled to any further payments or benefits as provided under this Section 4. (d) In the event that Employee accepts employment with, or provides any services to (whether as a partner, consultant, joint venturer or otherwise), any person or entity while Employee continues to receive any separation benefits pursuant to this Section 4, Employee shall immediately notify the Company of such acceptance and provide to the Company information with respect to such person or entity as the Company may reasonably request in order to determine if that person's or entity's products or services are competitive with the Company's. 5. Acceleration of Exercisability and Vesting of Stock Options Upon Change in Control. In the event of a Change in Control, all stock options granted to the Employee prior to the Change in Control (whether heretofore or hereafter granted) shall become immediately exercisable and vested in full effective as of the date thirty (30) days before the consummation of the transaction constituting such Change in Control. 6. Parachute Payments. In the event that any payment or benefit received or to be received by Employee pursuant to this Agreement or otherwise (collectively, the "Payments") would result in a "parachute payment" as described in section 280G of the Internal Revenue Code of 1986, as amended, notwithstanding the other provisions of this Agreement, the amount of such Payments will not exceed the amount which produces the greatest after-tax benefit to Employee. For purposes of the foregoing, the greatest after-tax benefit will be determined within thirty (30) days of the occurrence of such payment to Employee, in Employee's sole and absolute discretion. If no such determination is made by Employee within thirty (30) days of the occurrence of such payment, the Company will promptly make such determination in a fair and equitable manner. 7. Exclusive Remedy. Under any claim for breach of this Agreement or wrongful termination, the payments and benefits provided for in Section 4 shall constitute the Employee's sole and exclusive remedy for any alleged injury or other damages arising out of the cessation of the employment relationship between the Employee and the Company in the event of Employee's termination. Except as expressly set forth herein, the Employee shall be entitled to no other compensation, benefits, or other payments from the Company as a result of any termination of employment with respect to which the payments and/or benefits described in Section 4 have been provided to the Employee. 8. Proprietary and Confidential Information. The Employee agrees to continue to abide by the terms and conditions of the Company's confidentiality and/or proprietary rights agreement between the Employee and the Company. 9. Conflict of Interest.

Arbitration. Any claim, dispute or controversy arising out of this Agreement, the interpretation, validity or enforceability of this Agreement or the alleged breach thereof shall be submitted by the parties to binding arbitration by the American Arbitration Association in Santa Clara County, California; provided, however, that this arbitration provision shall not preclude the Company from seeking injunctive relief from any court having jurisdiction with respect to any disputes or claims relating to or arising out of the misuse or misappropriation of the Company's trade secrets or confidential and proprietary information. All costs and expenses of arbitration or litigation, including but not limited to attorneys fees and other costs reasonably incurred by the prevailing party, as determined by such arbitration or litigation, shall be paid by the other party. Judgment may be entered on the award of the arbitration in any court having jurisdiction. 11. Interpretation. Employee and the Company agree that this Agreement shall be interpreted in accordance with and governed by the laws of the State of California. 12. Conflict in Benefits. This Agreement shall supersede all prior arrangements, whether written or oral, and understandings regarding the subject matter of this Agreement; provided, however, that this Agreement is not intended to and shall not affect, limit or terminate (i) any plans, programs, or arrangements of the Company that are either in writing or regularly made available to a significant number of employees of the Company, (ii) any agreement or arrangement with the Employee that has been reduced to writing and which does not relate to the subject matter hereof, or (iii) any agreements or arrangements hereafter entered into by the parties in writing, except as otherwise expressly provided herein. 13.

Failure of the Company to obtain such agreement prior to the effectiveness of any such succession transaction shall be a breach of this Agreement and shall entitle the Employee to terminate his employment with the Company within three (3) months thereafter and to receive the benefits provided under Section 4 of this Agreement in the event of Termination Upon Change in Control. As used in this Agreement, "Company" shall mean the Company as defined above and any successor or assign to its business and/or assets as aforesaid which executes and delivers the agreement provided for in this Section 13 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law.
