Exhibit 10.20

EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT (this “Agreement”) is made as of December 19, 2007, by and between Xanodyne Pharmaceuticals, Inc., a Delaware corporation with a principal place of business at One Riverfront Place, Newport, Kentucky (the “Company”), and Greg Flexter, an individual (the “Employee”).

     The Company and the Employee have entered into an Employment Agreement dated as of June 12, 2007 (the “Existing Employment Agreement”). The Company desires to continue to employ the Employee as President and Chief Executive Officer, and the Employee desires to continue to be employed by the Company as President and Chief Executive Officer on the terms and conditions set forth herein. The Company and the Employee desire to amend and restate the Existing Employment Agreement in its entirety.

     In consideration of the mutual covenants and promises contained in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the parties to this Agreement, the parties agree as follows:

     1) EMPLOYMENT AND SUPERSESSION OF ALL PRIOR AGREEMENTS. The Company hereby employs the Employee and the Employee accepts employment upon the terms and conditions of this Agreement. This Agreement, together with all attachments, annexes and exhibits hereto, shall supersede and replace any and all agreements, written or oral, express or implied, between the Employee and the Company or any related or predecessor organization, relating to the subject matter hereof, including without limitation the Existing Employment Agreement. This Agreement, together with all attachments, annexes and exhibits hereto, constitutes the complete understanding between the parties relating to the subject matter hereof and thereof.

     2) DUTIES. The Employee will continue to be employed as President and Chief Executive Officer, reporting to the Board of Directors of the Company (the “Board”). During the Employee’s employment, the Employee agrees to serve and perform such duties consistent with being a President and Chief Executive Officer at such times and in such manner as the Company or the Board may reasonably from time to time direct. At the Company’s discretion, the Employee may be given additional duties or different duties, and this Agreement shall apply as well to any such duties assumed by Employee. During the term of this Agreement, the Employee agrees to faithfully perform the duties assigned to him or her to the best of his or her ability and to devote full and undivided time to the transaction of the Company’s business. The Employee agrees to abide by the rules, regulations, instructions, personnel practices and policies of the Company and any changes therein which may be adopted from time to time by the Company. As provided in the Existing Employment Agreement, the Employee has been elected by the stockholders of the Company in an action by written consent dated June 19, 2007 as a member of the Company’s Board of Directors, effective as of July 9, 2007.

     3) COMPENSATION.

          a) Base Salary. The Company shall pay the Employee, in periodic installments in accordance with the Company’s customary payroll practices, an annual base salary of $500,000, as may be adjusted from time to time by the Board or the Compensation Committee of the Board (the “Committee”), based upon a review of Company and Employee performance, which review shall occur at least annually; provided, however that effective as of January 1, 2008 the Employee’s annual base salary shall be increased to at least $550,000.

          b) Annual Bonus. The Employee will be eligible for an annual bonus based on achievement of objectives set by the Board or the Committee on an annual basis. The Employee’s target bonus will be 60% of the Employee’s base salary. Depending on results, the Employee’s actual bonus, if any, may be higher or lower. The Board or the Committee has the right to modify the bonus program at any time. The bonus award amount will be determined by the Board or Committee in its sole discretion. Notwithstanding the foregoing, for the 2007 calendar year, the Company will pay the Employee a minimum bonus payment of 50% of the base salary paid to Employee in 2007 (such that the 2007 bonus payment will be pro-rated based on salary actually paid in 2007), which bonus shall be paid to the Employee on or before March 15, 2008.

          c) Benefits. The Employee shall be entitled to receive those benefits generally provided to other full-time employees of the Company at substantially the same employment level. Such benefits are subject to change from time to time in the Company’s sole discretion.

          d) Vacation. The Employee shall be entitled to 25 days of paid vacation per year (prorated from July 8, 2007 for calendar year 2007), to be taken at such times as may be approved by the Board, the Committee or an officer designated by the Board or the Committee.

          e) Expense Reimbursement. The Company shall reimburse the Employee for all reasonable travel, entertainment and other expenses incurred or paid by the Employee in connection with, or related to, the performance of his or her duties, responsibilities or services under this Agreement, in accordance with policies and procedures, and subject to limitations, adopted by the Company from time to time.

          f) Stock Options.

               i) As provided in the Existing Employment Agreement, the Board has granted the Employee, in a resolution adopted on July 9, 2007, an option to acquire 1,750,000 shares of the Company’s Common Stock pursuant to and in accordance with the Company’s Amended and Restated 2001 Stock Incentive Plan at an exercise price of $0.98 per share.

               ii) On the first day of trading of the Company’s Common Stock on the NASDAQ Global

Market, the Company shall grant to the Employee an option to purchase 500,000 shares of the Company’s Common Stock (the “IPO Options”), subject to the execution and delivery by the Employee of an appropriate stock option agreement in substantially the form approved and adopted by the Board. The IPO Options shall (i) vest and become exercisable with respect to 25% of the shares on the first anniversary of the grant date and with respect to an additional 2.0833% of the shares at the end of each successive one-month period following the first anniversary of the grant date until the fourth anniversary of the grant date; (ii) be granted pursuant to and in accordance with the Company’s 2007 Stock Incentive Plan or the Company’s Amended and Restated 2001 Stock Incentive Plan and be subject to the terms and conditions of the applicable plan; (iii) have an exercise price per share equal to the closing sales price of the Company’s Common Stock on the first day of trading of the Company’s Common Stock on the NASDAQ Global Market. The number of shares of the Company’s Common Stock subject to the IPO Option shall be subject to appropriate adjustment for stock splits, combinations, recapitalizations and other similar events affecting the Company’s Common Stock. The IPO Options are the same options the granting of which was approved in a resolution adopted by the Board on November 2, 2007. The IPO Options together with the options to be granted to other employees of the Company pursuant to such resolution are generally referred to by the Company as the “IPO Bonus Plan.”

               iii) Future grants of options to the Employee will be at the discretion of the Board.

          g) Relocation. The Company agrees to reimburse Employee for all reasonable and necessary relocation expenses incurred in relocating to the Cincinnati area in accordance with the Company’s Relocation Policy in the form attached hereto as Annex B. Employee must coordinate his relocation through the Company’s Human Resources Department, and any eligible expenses incurred must be reported to the Company by July 9, 2008 in order to be reimbursed.

          h) Withholding. All salary, bonus and other compensation payable to the Employee shall be subject to applicable withholding taxes.

     4) EMPLOYMENT PERIOD.

          a) Employment Period. The period commencing on the date first written above and ending on the date on which this Agreement is terminated is referred to herein as the “Employment Period.” During the Employment Period, the Employee will be an at-will employee of the Company. The Employment Period shall be freely terminable for any reason by either party at any time; provided, however, that (i) if the Company terminates the Employee’s employment with the Company, the Company shall provide written notice of such termination to the Employee (subject, in the event of a termination for Cause, to any additional notice and cure provisions described in the definition of Cause set forth in Section 5(d)) and (ii) if the Employee terminates his or her employment with the Company for any reason other than for Good Reason (as defined in Section 5(d) and subject to the notice and cure provisions described therein), the Employee shall provide written notice of such termination to the Company at least three months prior to the effective date of such termination (the “Employee Notice Period”). The Company may reduce the Employee Notice Period in its sole and absolute discretion. During the Employee Notice Period, it is understood that the Employee shall continue to perform relevant duties for the Company and will assist the Company with transferring

the Employee’s responsibilities in an appropriate manner and take such actions as deemed necessary by the Company to assure a smooth transition.

          b) Cooperation. After notice of termination, the Employee shall cooperate with the Company, as reasonably requested by the Company, to effect a transition of the Employee’s responsibilities and to ensure that the Company is aware of all matters being handled by the Employee. The Company agrees to pay for reasonable travel and lodging expenses incurred by the Employee relating to this cooperation clause.

          c) Termination Date. For all purposes in this Agreement, “Termination Date” means the effective date of the Employee’s termination of employment with the Company.

     5) TERMINATION PAYMENTS.

          a) Termination for Any Reason. Upon termination of the Employee’s employment for any reason, the Employee will be entitled to: (i) all unpaid salary and vacation days accrued through the Termination Date and (ii) any unreimbursed business expenses. The Employee may also be eligible for other post-employment payments and benefits as provided in this Agreement or pursuant to other agreements or plans with the Company.

          b) Termination Not Related to a Change in Control.

               i) Except in a termination related to a Change in Control (as defined in Section 5(d)), which is covered in Section 5(c), if:

     (1) the Employee’s employment is involuntarily terminated by the Company other than for (x) Cause (as defined in Section 5(d) and subject to the notice and cure provisions described therein), (y) death or (z) Disability (as defined in Section 5(d)), or

     (2) the Employee voluntarily terminates his or her employment for Good Reason (as defined in Section 5(d) and subject to the notice and cure provisions described therein),

then, subject to the Employee delivering an executed release in the form attached hereto as Exhibit A or, at the Company’s election, such other form that the Company is then using for employees similarly situated to the Employee, the Company will provide the Employee the following:

     (A) a lump sum equivalent of 12 months of the Employee’s base salary and target bonus as in effect on the Termination Date; and

     (B) for 12 months following the Termination Date, the Employee also shall be entitled to continuation, at the Company’s expense, of group medical, dental, long-term disability, accidental death and disability, and life insurance benefits from the Company to the extent

permitted under such plans or as otherwise approved by the Board, as in effect immediately prior to the Termination Date; provided, however, that in the event continuation of such benefits is not permitted under such plans, the Company shall pay to Employee the cash equivalent of such benefits not permitted to be covered under such plans; and

     (C) the accrued target bonus earned during the calendar year of severance on a pro rata basis.

               ii) The continuation of benefits at the Company’s expense pursuant to Section 5(b)(i)(B) shall be concurrent with any obligation of the Company to provide continuation of coverage under Section 4980B of the Internal Revenue Code of 1986 or Sections 601 et. seq. of the Employee Retirement Income Security Act of 1974 (collectively, “COBRA”), and shall not replace or extend the Employee’s right to continued coverage under COBRA.

          c) Termination Related to a Change in Control.

               i) In the event that one of the following occurs:

     (1) the Employee’s employment is involuntarily terminated by the Company other than for (x) Cause (as defined in Section 5(d) and subject to the notice and cure provisions described therein), (y) death or (z) Disability (as defined in Section 5(d)), either within 90 days prior to, on the date of or within one year after a Change in Control; or

     (2) the Employee terminates his or her employment for Good Reason (as defined in Section 5(d) and subject to the notice and cure provisions described therein) within one year after such Change in Control,

then, subject to the Employee delivering an executed release in the form attached hereto as Exhibit A or, at the Company’s election, such other form that the Company is then using for employees similarly situated to the Employee, the Company will provide the Employee the following:

     (A) a lump sum equivalent of 24 months of the Employee’s base salary and target bonus as in effect on the Termination Date; and

     (B) full vesting of all stock options or other equity incentive awards that are outstanding and not vested as of the Termination Date; and

in the event continuation of such benefits is not permitted under such plans, the Company shall pay to Employee the cash equivalent of such benefits not permitted to be covered under such plans; and

     (C) the accrued target bonus earned during the calendar year of severance on a pro rata basis.

               ii) The continuation of benefits at the Company’s expense pursuant to Section 5(c)(i)(C) shall be concurrent with any obligation of the Company to provide continuation of coverage under COBRA, and shall not replace or extend the Employee’s right to continued coverage under COBRA.

               iii) “Cause” shall mean: (a) the Employee’s willful misconduct with respect to the business and affairs of the Company or any subsidiary thereof, (b) the Employee’s gross neglect of duties or failure to act which can reasonably be expected to affect materially and adversely the business or affairs of the Company or any subsidiary thereof, (c) the Employee’s material breach of any of the agreements contained herein, any other written agreement between the Company and the Employee, or any written policy of the Company governing the Employee’s conduct or employment whether now existing or hereafter created, or the Employee’s breach of the Non-Compete Agreement (as defined in Section 6), (d) the commission by the Employee of an act involving moral turpitude relating to the Company, dishonesty in performance of employment duties or fraud, (e) the Employee’s conviction of any felony, or of any misdemeanor involving fraud, theft, embezzlement, forgery or moral turpitude, (f) possession or use of or impairment on account of illegal drugs, (g) abandonment of employment duties or (h) conduct on the part of Employee relating to the Company’s business or his or her employment duties (which is not authorized, directed or approved by the Company) which results in governmental sanctions being imposed on the Company or the Employee.

Before “Good Reason” has been deemed to have occurred, the Employee must give the Company written notice detailing why the Employee believes a Good Reason event has occurred and such notice must be provided to the Company within 30 days of the Employee’s actual knowledge of the initial occurrence of such alleged Good Reason event. The Company shall then have 30 days after its receipt of written notice to cure the item cited in the written notice so that “Good Reason” will have not formally occurred with respect to the event in question. A termination of employment due to

Good Reason shall occur no later than 75 days after the Employee’s actual knowledge of the condition giving rise to Good Reason.

     6) PROPRIETARY INFORMATION AND NON-COMPETE AGREEMENT. The Employee has executed the Proprietary Information and Invention and Non-Compete Agreement, a copy of which is attached hereto and the text of which is incorporated herein as Annex A (the “Non-Compete Agreement”) and covenants that the Employee will comply with the terms of the Non-Compete Agreement.

     7) INTERNAL REVENUE CODE SECTION 409A. The following rules shall apply with respect to distribution of the payments and benefits, if any, to be provided to the Employee under Section 5:

          a) It is intended that each installment of the payments and benefits provided under Section 5 shall be treated as a separate “payment” for purposes of Section 409A of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and the guidance issued thereunder (“Section 409A”). Neither the Company nor the Employee shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A;

          b) If, as of the date of the “separation from service” of the Employee from the Company, the Employee is not a “specified employee” (each, for purposes of this Agreement, within the meaning of Section 409A), then each installment of the payments and benefits shall be made on the dates and terms set forth in Section 5; and

          c) If, as of the date of the separation from service of the Employee from the Company, the Employee is a specified employee, then:

               i) Each installment of the payments and benefits due under Section 5 that, in accordance with the dates and terms set forth herein, will in all circumstances, regardless of when the separation from service occurs, be paid within the Short-Term Deferral Period (as defined below) shall be treated as a short-term deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A. For purposes of this Agreement, the “Short-Term Deferral Period” means the period ending on the later of (A) the 15th day of the third month following the end of the Employee’s tax year in which the Employee’s separation from service occurs and (B) the 15th day of the third month following the end of the Company’s tax year in which the Employee’s separation from service occurs; and

               ii) Each installment of the payments and benefits due under Section 5 that is not paid within the Short-Term Deferral Period and that would, absent this subsection, be paid within the six-month period following the separation from service of the Employee shall not be paid until the date that is six months and one day after such separation from service (or, if earlier, the death of the Employee), with any such installments that are required to be delayed being accumulated during the six-month period and paid in a lump sum on the date that is six months and one day following the Employee’s separation from service and any subsequent installments, if any, being paid

in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence shall not apply to any installment of payments and benefits if and to the maximum extent that that such installment is deemed to be paid under a separation pay plan that does not provide for a deferral of compensation by reason of the application of Treasury Regulation 1.409A-1(b)(9)(iii) (relating to separation pay upon an involuntary separation from service) or Treasury Regulation 1.409A-1(b)(9)(iv) (relating to reimbursements and certain other separation payments). Such payments due under Section 5 shall bear interest at an annual rate equal to the prime rate as set forth in the Eastern edition of the Wall Street Journal on the Termination Date, from the Termination Date to the date of payment. Any installments that qualify for the exception under Treasury Regulation Section 1.409A-1(b)(9)(iii) must be paid no later than the last day of the second taxable year of the Employee following the taxable year of the Employee in which the separation from service occurs.

     8) INTERNAL REVENUE CODE SECTION 280G. In the event that it is determined that any payment or distribution of any type to the Employee or for the Employee’s benefit made by the Company, by any of its affiliates, by any Person who acquires ownership or effective control or ownership of a substantial portion of the Company’s assets (within the meaning of Section 280G of the Code and the regulations thereunder) or by any affiliate of such Person, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties with respect to such excise tax (such excise tax, together with any such interest or penalties, are collectively referred to as the “Excise Tax”), then such payments or distributions or benefits shall be payable either: (a) in full or (b) in a lesser amount reflecting a reduction in payments to the extent necessary to result in no portion of such payments or distributions or benefits being subject to the Excise Tax. Method (b) shall be used unless method (a) provides a higher after-tax benefit to the Employee. If method (b) is used, then the Employee shall have the right to determine which payments or benefits will be reduced and in what magnitude. The Employee and the Company shall furnish such documentation and documents as may be necessary for the Company’s independent external accountants to perform the requisite computations and analysis contemplated by this Section 8.

     9) REMEDIES UPON BREACH. The Employee acknowledges that the restrictions contained in this Agreement are necessary for the protection of the business and goodwill of the Company and are reasonable for such purpose. The Employee agrees that any breach of this Agreement by the Employee will cause irreparable damage to the Company and that in the event of such breach, the Company shall be entitled, in addition to monetary damages and to any other remedies available to the Company under this Agreement and at law, to equitable relief, including without limitation injunctive relief, and to payment by the Employee of all costs incurred by the Company in enforcing the provisions of this Agreement.

     10) ATTORNEYS’ FEES. If either party to this Agreement breaches any of the terms hereof, that party shall pay to the non-defaulting party all of the non-defaulting party’s costs and expenses, including without limitation attorneys’ fees, incurred by that

party in enforcing the terms of this Agreement.

     11) WAIVER OF TRIAL BY JURY. THE PARTIES TO THIS AGREEMENT DESIRE TO AVOID THE ADDITIONAL TIME AND EXPENSE RELATED TO JURY TRIAL OF ANY DISPUTES ARISING HEREUNDER. THEREFORE, IT IS MUTUALLY AGREED BY AND BETWEEN THE PARTIES TO THIS AGREEMENT THAT THEY SHALL AND HEREBY DO WAIVE TRIAL BY JURY OF ANY CLAIM, COUNTERCLAIM, OR THIRD-PARTY CLAIM, INCLUDING WITHOUT LIMITATION ANY AND ALL CLAIMS OR INJURY OR DAMAGES, BROUGHT BY EITHER PARTY AGAINST THE OTHER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS AGREEMENT. THE PARTIES ACKNOWLEDGE AND AGREE THAT THIS WAIVER IS KNOWINGLY, FREELY, AND VOLUNTARILY GIVEN, IS DESIRED BY BOTH PARTIES, AND IS IN THE BEST INTERESTS OF BOTH PARTIES.

     12) ASSIGNMENT. The Employee acknowledges that services are unique and personal. Accordingly, the Employee may not assign rights or obligations under this Agreement.

     13) SUCCESSORS. This Agreement shall be binding upon, and inure to the benefit of, any successor to all or substantially all of the Company’s business and/or assets, and the Company will require any such successor to expressly assume and agree in writing to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. For all purposes under this Agreement, the term “Company” shall include any successor to the Company’s business and/or assets which becomes bound by this Agreement by contract, operation of law or otherwise. This Agreement will inure to the benefit of and be enforceable by the Employee and the Employee’s personal or legal representatives, executors, estate, trustee, administrators, successors, heirs, distributees, devisees and legatees, as applicable. If the Employee dies and any amounts become payable under this Agreement, the Company will pay those amounts to the Employee’s estate or named beneficiary, as applicable, except as otherwise may be required by applicable law.

     14) WAIVER AND AMENDMENT. No waiver of any term or condition of this Agreement shall be effective unless in writing and signed by the party so waiving. No amendment to this Agreement shall be valid unless in writing and signed by the Company and Employee.

     15) SEVERABILITY. If any provision of this Agreement or any attachment, annex or exhibit hereto, is invalid under any applicable statute or rule of law, it is to that extent to be deemed omitted. The remainder of the Agreement, and such attachments, annexes and exhibits, shall be valid and enforceable to the maximum extent possible.

     16) GOVERNING LAW AND JURISDICTION. The parties agree that this Agreement, and all attachments, annexes and exhibits hereto, shall be construed and enforced in accordance with the laws of the Commonwealth of Kentucky, and that the courts of the Commonwealth of Kentucky have exclusive jurisdiction over actions to

enforce any term of this Agreement or any attachment, annex or exhibit hereto or any action alleging a breach of this Agreement.

     17) HEADINGS. Headings in this Agreement are for convenience only and shall not be used to interpret or construe its provisions.

     18) NOTICE. Any notice or communications that are required or that may be given pursuant to this Agreement shall be in writing and shall be deemed to be duly given if (a) delivered personally or (b) sent by first class mail, postage prepaid, return receipt requested or prepaid via a reputable nationwide overnight courier, in each case in this clause (b), at the addresses specified in the preamble to this Agreement or such other place as may be specified in writing by a party from time to time. Any notice or communications shall be deemed to be effective (i) if personally delivered, when delivered in hand to the party to which it is directed, (ii) if sent by first class mail, postage prepaid, on the third business day following the day of the dispatch thereof or (iii) if sent via a reputable overnight courier service, one business day following the day it is sent.

     19) COUNTERPARTS. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which taken together shall constitute one and the same instrument.

     3. I hereby assign to the Company all of my right, title and interest in and to the Proprietary Subject Matter and any and all related patent rights, copyrights and applications and registrations therefor. At the request and expense of the Company, but without further compensation to me, I shall do such acts, and execute, acknowledge and deliver all such papers, including without limitation patent and copyright applications or assignments, as may be necessary or desirable in the sole discretion of the Company to obtain, maintain, protect or vest in the Company the entire right, title and interest in and to Proprietary Subject Matter and any patent applications, patents, copyright or other proprietary rights of any kind relating thereto, in all countries of the world; including without limitation rendering such assistance as the Company may request in any contemplated or pending litigation, patent office proceeding, or other proceeding. I hereby appoint the Company my attorney-in-fact to execute and deliver any such documents on my behalf in the event I should fail or refuse to do so within a reasonable

period following the Company’s request. I understand that, to the extent this Non-Compete Agreement shall be construed in accordance with the laws of any state which limits assignability to the Company of certain employee inventions, this Non-Compete Agreement shall be interpreted not to apply to any such invention which a court rules or the Company agrees is subject to such state limitation.

     4. I shall not disclose or cause others to disclose to the Company, or induce the Company to use, any information or material, which is the property of any former or concurrent employer, or any other person or entity with whom I have an agreement or to whom I owe a duty to keep such information in confidence. Those persons or entities with whom I have such agreements or to whom I owe such a duty are identified on Exhibit I attached hereto. I hereby represent to the Company that, except as identified on Exhibit I attached hereto, I am not bound by any agreement or any other previous or existing business relationship which conflicts with or prevents the full performance of my duties and obligations to the Company (including without limitation my duties and obligations under this Non-Compete Agreement or any other agreement with the Company) during my employment.

     5. Since the work for which I am employed and upon which I shall be engaged will include Company knowledge and information of a private, confidential, or secret or proprietary nature, I shall not, except as required in the conduct of the Company’s business or as authorized in writing by the Company, publish, disclose, or make use of, or authorize anyone else to publish, disclose or make use of any such knowledge or information, of a confidential, secret or proprietary nature or other information which in any way relates to the business, business relationships and financial affairs of the Company or the design, construction, manufacture or sale of the Company’s products or services.

     6. I will keep and maintain adequate and current written records of my work and inventions at all times and stages, in the form of notes, sketches, drawings, memoranda, and reports, which records shall be and remain the property of and be available to the Company at all time. All documents, written information and other items including without limitation notes, sketches, manuals, blueprints, notebooks, products, tools, fixtures, records and information relating to the business of the Company and all copies thereof, made or obtained by me while employed by the Company shall be the exclusive property of the Company and shall be delivered by me to the Company on termination of my employment (whether such termination is caused by act of the Company or by my own resignation or other act) or at any time as reasonably requested by the Company.

     7. During the term of my Employment Agreement and for a period of 12 months following the Termination Date (as defined in the Employment Agreement), except that in the event of a termination of my employment with the Company as described in Section 5(c)(i) of the Employment Agreement, the period shall be 24 months following the Termination Date, and whether as owner, partner, officer, director, employee, consultant, investor, lender or otherwise, except as the holder of not more than 1% of the outstanding stock of a publicly-held company, I agree not to: (i) engage in any

business or enterprise that is competitive with the Company’s business, including without limitation to any business or enterprise that develops, manufactures, markets, licenses, sells or provides any product or service that competes with any product or service developed, manufactured, marketed, licensed, sold or provided, or planned to be developed, manufactured, marketed, licensed, sold or provided, by the Company or any of its subsidiaries while I am or was employed by the Company; (ii) solicit or accept orders with or for any of the products or business activities that are competitive with the Company’s products or business activities; (iii) solicit or entice away any employee from the Company, or hire any such employee; (iv) solicit or request investments or funds from any other person or entities that are affiliated with the Company or for any entity which competes with the Company; and/or (v) solicit, divert or take away or attempt to divert or take away, the business or patronage of any of the clients, customers or accounts, or prospective clients, customers or accounts of the Company with respect to products or business activities that are competitive with the Company’s products or business activities. I acknowledge that even at such times as I may be entitled to compete with the Company after the periods of restriction in this Non-Compete Agreement or my Employment Agreement, the provisions of this Non-Compete Agreement relating to the confidential nature and ownership of Proprietary Subject Matter in favor of the Company will survive and continue to be binding upon me.

     8. Upon termination of my employment with the Company, I shall, if requested by the Company, reaffirm in writing all of the obligations set forth in paragraph 1 through 7 of this Non-Compete Agreement. All such obligations expressly survive the termination of my employment with the Company.

     9. Excepted from this Non-Compete Agreement are only such inventions, improvements, ideas, suggestions, proposals, writings and the like relating to any phase of the Company’s business made or conceived by me prior to my employment with the Company which are (a) embodied in a United States Letters Patent, Copyright Registration or an application for United States Letters Patent or Copyright Registration filed prior to the commencement of my employment; (b) in the physical possession of a former employer who owns them; or (c) disclosed in detail in Exhibit I attached hereto.

ANNEX “B”
to the Employment Agreement

XANODYNE PHARMACEUTICALS, INC.

RELOCATION POLICY

I.		Purpose
		To define the Company’s policy governing relocation expenses for all employees and, to provide a summary of relocation services provided to employees.
II.		Scope
		This Policy is applicable to all employees who relocate for employment with Xanodyne Pharmaceuticals, Inc. We are dedicated to providing you with personalized service and professional assistance with the necessary tools to facilitate a smooth transition to your new location.

	a.		Policy
			The Company will pay or reimburse certain reasonable relocation expenses to a full-time employee who is offered the company’s relocation package. To be eligible for reimbursement of relocation-related expenses, IRS regulations require that the employee’s commuting distance be at least fifty (50) miles from the former residence or the Company’s work site. This measurement is based on the most direct, commonly traveled route. Example: If the old commuting distance to work is three (3) miles, then the new commuting distance to work would have to exceed fifty-three (53) miles in order to be eligible for relocation benefits.
			The IRS also requires that reimbursement of all relocation-related expenses must be made within the first twelve (12) months after the effective date of the relocation. The initiation of the expense must occur before the end of the 12-month period, even if the activity connected with that expense is not completed until after the 12 (twelve) months has ended. Example: If the employee’s household goods are loaded on the truck prior to the end of the 12 (twelve) months, but not delivered to the new location until sometime later, the expense would be covered.
			If an employee voluntarily leaves the company within eighteen (18) months from the date of transfer, the employee will be required to reimburse the Company a prorated portion of the relocation expenses and gross-up expenses paid by the Company based on the following scale:

	•		Prior to six (6) months — 100% reimbursable.
	•		Between seven (7) months and eighteen (18) months the reimbursement will be reduced by one-twelfth (1/12) for each month that the employee was with the Company.

III.

Reimbursable Relocation Expenses covered under this policy are as follows:

	a.		House-Hunting Assistance
			You and your spouse (if applicable) are entitled to two trips, for up to a total of four (4) days, to search for a residence in your new work area. You will be reimbursed for all reasonable expenses incurred during your trip, (e.g., lodging, meals, travel, telephone, rental car and gasoline, parking and tolls). All travel arrangements should be made through the Company’s travel agency by the employee.
			Please be sure to contact your Human Resources Department prior to scheduling your house-hunting trip to assure maximum use of your time and a successful outcome.
	b.		Closing Costs
			The company will reimburse for the following qualifying closing costs for the sale and/or purchase of a house:

	•		Appraisal Fee
	•		Attorney’s Fees (if required by local custom-not to exceed five-hundred ($500.00) dollars.)
	•		Courier Service
	•		Credit Report
	•		Document Preparation
	•		Escrow Fee
	•		Homeowner’s Document Transfer Fee
	•		Inspections (if required by lender)
	•		Loan Application Fee
	•		Loan/Lender Fees and Points of up to 2% of mortgage amount
	•		Notary Fees
	•		Real Estate Commissions for Seller
	•		Recording Fees
	•		Settlement/Closing Fee
	•		Survey (if required by lender)
	•		Tax Stamps
	•		Title Search/Abstract

	c.		Lease Breaking Fees
			If you are living in a rental unit and will be required to pay a penalty for early lease cancellation, the company will reimburse you up to but not exceeding two (2) months of lease breaking expenses. Documentation showing the penalty is required in order to obtain reimbursement.
	d.		Transportation And Storage Of Household Goods
			The company has contracted with an approved carrier to manage your move. Your Human Resources Department will initiate this service.

The company will cover the following costs related to moving your household goods:

	•		Packing and unpacking your household goods.
	•		Transportation of your goods from your existing home to your new home.
	•		Disconnecting and connecting of major appliances (limited to normal appliance services).
	•		Shipment of two (2) cars.
	•		Sixty (60) days of temporary storage of household goods.

The moving company will submit all bills directly to the company for processing and payment. Please note, there are some items that will not be moved under the company’s relocation package, as listed below:

	•		Hazardous Material: Flammable liquids, aerosol cans, paints, fuel kerosene, matches, ammunition, etc.
	•		Perishable Items and Liquor: Perishable food, liquor, beer, wine, plants, flowers, shrubs, and other similar items.

•

On occasion, household plants may be moved on the van; however, this at your own risk.

	•		Pets: Any types of pets or livestock are your moving responsibility. If possible, your pet should travel with your family.
	•		Bulky or Heavy Items: Boats, utility trailer, hobby equipment, snowmobiles, firewood, bricks, patio blocks, storage sheds, and similar types of items.

			You, your spouse or other adult member must be present during the packing, unloading and unpacking of household goods and must carefully review the inventory list prior to signing.
	e.		Loss Or Damage Claims
			If your household goods are damaged during transportation and/or storage, you are insured for the full replacement value of your household goods up to fifty-thousand ($50,000.00) dollars. You must pre-designate your valuable possessions (e.g., antiques, original art work) along with the corresponding appraised value for each item prior to your actual move date. We recommend that you discuss these items with the approved carrier to ensure that they will be insured during the move.
			You may be required to pay for insurance for extraordinary items that are above and beyond a reasonable cost. Coverage of stored goods is limited to sixty (60) days and must be in the care, custody, and control of the original moving company responsible for your household goods.
			If damage does occur during storage or the move, you will be required to file an insurance claim through the moving coordinator as soon as you notice the damage.

	f.		Travel To New Location:
			It is expected that you will drive your car(s) to your new residence. Employees are expected to drive the most direct route available in order to ensure a timely relocation.
			The following reimbursable expenses will be paid during your travel:

	•		Meals (per diem of fifty ($50.00) dollars per day), lodging, parking, mileage (at the current reimbursable rate) for each day of travel. This includes travel from the old location and the arrival day at the new location.
	•		If your household pets cannot travel with you by car, you must arrange for their shipment. You will be reimbursed shipping charges (including pet carriers), insurance cost and required health certificates for up to two household pets.

	g.		Temporary Living
			Temporary housing expenses, not to exceed two-thousand ($2,000) dollars per month, will be reimbursed for up to ninety (90) days, so as not to incur duplicate housing expenses. Your Human Resources Department will assist you in finding temporary housing.
	h.		Return Visits
			If it is necessary for you to move to your new work location before your family, you are entitled to reimbursement for airline tickets or personal automobile mileage for two (2) trips home. Your spouse may visit you in the new location in lieu of your trips home, provided there is no additional cost to the Company. If your spouse visits you, only your spouse’s transportation cost will be covered.
			All return visits will be covered as business travel expenses. All airline reservations should be coordinated through the company’s travel agent and only coach airfare will be reimbursed. Transportation expenses to and from the airport will also be reimbursed; car rentals are not a reimbursable expense.
	i.		Important Tax Information
			The Internal Revenue Service (IRS) considers reimbursements of allowances for moving expenses as compensation to the transferred employee. These reimbursements and/or allowances are subject to Federal and State Income Tax, as well as Social Security taxes. Accordingly, such relocation expenses will be reported on your annual W-2.
			In order to offset some of the tax impact created by this additional income, you will be provided with an income tax allowance or gross-up for the estimated additional you will be required to pay. The income tax allowance includes an amount to offset the tax liability by the gross-up itself (e.g., gross-up on the

gross-up). To be consistent in calculating the gross-up amount for eligible employees and for administrative efficiency, Xanodyne will use a standard, all inclusive tax rate of 40% in calculating the gross-up amount. This rate is applicable for all relocating employees. The following example illustrates how the gross-up amount will be calculated:

			Example: Taxable expenses reimbursed to the employee: $12, 372 Total gross-up provided: [taxable expenses / (1-tax rate] or [12,372 / .60 = $20,620]
			In the above example, the employee would have total taxable income of $20,620 included on his / her W-2 related to the relocation. This amount would include the taxable relocation expense reimbursement of $12,372, plus the gross up tax component of $8,248 ($20,620 — $12,372). The pay stub for this employee will reflect the inclusion of $20,620 in income, with tax withholdings of $8,248. The employee will not receive a check for any amount, since the taxable reimbursement amount will have already been paid on the employee’s behalf.
			You are encouraged to keep careful records of all transactions and expenditures during your move and to seek the assistance of a professional tax consultant to ensure that you have considered all the tax implications of your move.

Relocation Repayment Agreement

The undersigned agrees to the repayment terms outlined in the Xanodyne Pharmaceuticals, Inc. Relocation Policy. My signature also confirms that I have read, accept, and understand the attached policy guidelines.
