Exhibit 10.10

EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into as of May 24, 2006 (the “Effective Date”), between Aspect Software, Inc., a Delaware corporation (the “Company”), and Michael Sheridan (“Employee”).

The Company and Employee desire to enter into this Agreement to provide the terms on which Employee will serve as the Vice President of Marketing of the Company.

The parties hereto agree as follows:

1. Employment. The Company hereby employs Employee, and Employee hereby accepts employment with the Company, upon the terms and conditions set forth in this Agreement for the period beginning as of the Effective Date and ending as provided in Section 4 hereof (the “Employment Period”).

2. Position and Duties.

(a) During the Employment Period, Employee will serve as the Vice President of Marketing of the Company, subject to the overall direction and authority of Employee’s manager or supervisor as designated by the Company from time to time.

(b) Employee will devote his or her reasonable best efforts and his or her full business time and attention to the business and affairs of the Company and its affiliates; provided that nothing in this Section 2(b) will prohibit Employee from devoting a reasonable amount of time to charitable or other similar activities. Employee will perform his or her duties and responsibilities hereunder to the best of his or her abilities in a diligent, trustworthy, businesslike and efficient manner.

3. Base Salary and Benefits.

(a) During the Employment Period, Employee’s base salary will be $210,000.00 per annum and will be subject to review by the Company’s Chief Executive Officer (the “CEO”) on an annual basis (the “Base Salary”), which salary will be payable in regular installments in accordance with the Company’s general payroll practices and will be subject to customary withholding.

(b) During the Employment Period, Employee will be entitled to participate in all of the Company’s employee benefit programs (including cash bonus programs) for which managerial employees of the Company are generally eligible in accordance with the terms and conditions of such programs as the same may be amended or modified from time to time.

(c) The Company will reimburse Employee for all reasonable expenses incurred by him or her in the course of performing his or her duties under this Agreement which are consistent with the Company’s policies in effect from time to time with respect to travel, entertainment and other business expenses, subject to the Company’s requirements with respect to reporting and documentation of such expenses.

4. Term.

(a) The Employment Period will commence as of the Effective Date and (i) will terminate upon Employee’s resignation, death or Disability (as defined in Section 4(e) below) and (ii) may be terminated by the Company at any time for Cause (as defined in Section 4(f) below) or without Cause.

(b) Subject to the other terms and conditions of this Section 4(b), if the Employment Period is terminated by the Company without Cause during the term of this Agreement, Employee will be entitled to receive his or her Base Salary described in Section 3(a) above and continuation of medical and dental benefits coverage during the six (6) month period immediately following any such termination (subject to the following sentence, the “Severance Period”). The Severance Period shall terminate immediately (and no further payments shall be due or payable under this Section 4(b)) if, prior to the end of the period specified in the preceding sentence, Employee becomes employed by or is engaged as a consultant or independent contractor on a full-time basis (i.e 30 or more hours per week) with any person or entity other than the Company and its affiliates. Any amounts payable under this Section 4(b) will be payable at such times as such amounts would have been payable had Employee’s employment not been terminated. Notwithstanding anything in this Agreement to the contrary, the Company will have no obligation to pay any amounts payable under this Section 4(b) during such times as Employee is in breach of Sections 5, 6 or 7 hereof. As a condition to the Company’s obligations (if any) to make the payments described in this Section 4(b), Employee will execute and deliver a general release in form and substance reasonably satisfactory to the Company.

(c) If the Employment Period is terminated by the Company for Cause or pursuant to Section 4(a)(i) above, Employee will be entitled only to receive his or her Base Salary through the date of termination.

(d) Except as otherwise expressly provided in Section 4(b) above, all of Employee’s rights to salary, bonuses, fringe benefits and other compensation hereunder (if any) which accrue or become payable after the termination of the Employment Period will cease upon such termination. The Company may offset any amounts Employee owes the Company or its affiliates against any amounts the Company owes Employee hereunder. Employee’s termination of employment with the Company for any reason shall be deemed to automatically remove Employee, without further action, from any and all offices held by Employee with the Company or its affiliates.

(e) For purposes of this Agreement, “Disability” (i) means any physical or mental incapacitation which results in Employee’s inability to perform his or her duties and responsibilities for the Company for a total of 120 days during any twelve-month period, as determined by the CEO in his good faith judgment and (ii) will be deemed to have occurred on the 120^th day of such inability to perform.

2

(f) For purposes of this Agreement, “Cause” means (i) the entering of a guilty plea or conviction of a felony or any other act or omission involving dishonesty, disloyalty or fraud with respect to the Company or any of its affiliates or any of their customers or suppliers, (ii) conduct tending to bring the Company or any of its affiliates into substantial public disgrace or disrepute, (iii) substantial and repeated failure to perform duties as reasonably directed by the CEO or his designees, (iv) gross negligence or willful misconduct with respect to the Company or any of its affiliates or (v) any other material breach of this Agreement.

5. Confidential Information. Employee acknowledges that the information, observations and data (including, without limitation, trade secrets, know-how, research and product plans, customer lists, software, inventions, processes, formulas, technology, designs, drawings, specifications, marketing and advertising materials, distribution and sales methods and systems, sales and profit figures and other technical and business information) concerning the business or affairs of the Company or any of its affiliates obtained by him or her while employed by the Company (“Confidential Information”) are the property of the Company or such affiliate. Therefore, Employee agrees that he or she shall not disclose to any unauthorized person or use for his or her own purposes any Confidential Information without the prior written consent of the Company, unless and to the extent that the aforementioned matters become generally known to and available for use by the public other than as a result of Employee’s acts or omissions to act. Employee will deliver to the Company at the termination of the Employment Period, or at any other time the Company may request, all memoranda, notes, plans, records, reports, computer tapes, printouts and software and other documents and data (and copies thereof) to the extent containing Confidential Information or Work Product (as defined in Section 6 below) of the Company or any of its affiliates which he or she may then possess or have under his or her control.

6. Inventions and Patents. Employee acknowledges that all inventions, innovations, improvements, developments, methods, designs, analyses, drawings, reports and all similar or related information (whether or not patentable) which relate to the Company’s or any of its affiliates’ actual or anticipated business, research and development or existing or future products or services and which are conceived, developed or made by Employee while employed by the Company (“Work Product”) belong to the Company or such affiliate. Employee shall promptly disclose such Work Product to the Company and perform all actions requested by the Company (whether during or after the Employment Period) to establish and confirm such ownership (including, without limitation, assignments, consents, powers of attorney and other instruments).

7. Noncompete: Non-Solicitation.

(a) Employee acknowledges that Employee’s services to the Company require the use of information including a formula, pattern, compilation, program, device, method, technique, or process that the Company has made reasonable efforts to keep confidential and that derives independent economic value, actual or potential, from not being generally known to the public or to other persons who can obtain economic value from its disclosure or use (“Trade Secrets”). Employee further acknowledges and agrees that the Company would be irreparably damaged if Employee were to provide similar services requiring the use of such Trade Secrets to any person or entity competing with the Company or engaged in a similar business. Therefore, Employee agrees that during the Employment Period and during the twelve (12) month period immediately thereafter (the “Protection Period”), he or she will not, either directly or indirectly, for himself or herself or any other person or entity (i) induce or attempt to induce any employee of the Company or any of its affiliates to leave the employ of the Company or such affiliate, or in any way interfere with the relationship between the Company or any affiliate and any employee thereof, (ii) hire any person who is (or in the case of a former employee, was an employee of the Company or any affiliate at any time during the 180 day period prior to any attempted hiring by Employee) an employee of the Company or any affiliate, (iii) induce or attempt to induce any customer, supplier, licensee, licensor or other business relation of the Company or any affiliate to cease doing business with the Company or such affiliate, or in any way interfere with the relationship between any such customer, supplier, licensee, licensor or business relation and the Company or any affiliate (including, without limitation, making any negative statements or communications about the Company or its affiliates) or (iv) Participate in any business in which he would be reasonably likely to employ, reveal, or otherwise utilize Trade Secrets used by the Company prior to the Executive’s termination in any geographical area in which the Company or any of its affiliates conduct business. “Participate” includes any direct or indirect interest in any enterprise, whether as an officer, director, employee, partner, sole proprietor, agent, representative, independent contractor, consultant, executive, franchisor, franchisee, creditor, owner or otherwise; provided that the foregoing activities shall not include the passive ownership (i.e., Employee does not directly or indirectly participate in the business or management of the applicable entity) of less than 5% of the stock of a publicly-held corporation whose stock is traded on a national securities exchange.

(b) Employee agrees that the aforementioned covenant contained in Section 7(a) is reasonable with respect to its duration, geographical area and scope. In particular, Employee acknowledges and agrees that the Company and its affiliates conduct their businesses on a worldwide basis and that the geographic scope of the covenant contained in Section 7(a) is necessary to protect the goodwill and Confidential Information of the Company and its affiliates. Employee further acknowledges that the restrictions contained in Section 7(a) do not impose an undue hardship on him or her due to the fact that he or she has general business skills which may be used in industries other than those in which each of the Company and its affiliates conduct their businesses and do not deprive Employee of his or her livelihood. Employee agrees that the covenants made in Section 7(a) shall be construed as agreements independent of any other provision(s) of this Agreement and shall survive any order of a court terminating any other provision(s) of this Agreement.

(c) If, at the time of enforcement of Sections 5, 6 or 7 of this Agreement, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area.

(d) Because Employee’s services are unique and because Employee has access to Confidential Information and Work Product, the parties hereto agree that money damages may not be an adequate remedy for any breach of this Agreement. Therefore, in the event a breach or threatened breach of this Agreement, the Company or its successors or assigns may, in addition to other rights and remedies existing in their favor, apply to any court for specific performance and/or injunctive or other relief in order to enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security). In addition, in the event of an alleged breach or violation of this Section 7, the Protection Period will be tolled until such breach or violation has been duly cured. Employee agrees that the restrictions contained in Sections 5, 6 and 7 are reasonable.

8. Additional Acknowledgments. Employee acknowledges that the provisions of Sections 5, 6 and 7 are in consideration of: (i) employment with the Company and (ii) additional good and valuable consideration as set forth in this Agreement. Employee expressly agrees and acknowledges that the restrictions contained in Sections 5, 6 and 7 do not preclude Employee from earning a livelihood, nor do they unreasonably impose limitations on Employee’s ability to earn a living. Employee acknowledges that he or she has carefully read this Agreement and has given careful consideration to the restraints imposed upon Employee by this Agreement.

9. Other Businesses. As long as Employee is employed by the Company, Employee agrees that he or she will not, except with the express written consent of the Company, become engaged in, render services for, or permit his or her name to be used in connection with any business other than the business of the Company or any of its affiliates.

10. Employee’s Representations. Employee hereby represents and warrants to the Company that (i) the execution, delivery and performance of this Agreement by Employee does not and will not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree to which Employee is a party or by which he or she is bound, (ii) Employee is not a party to or bound by any employment agreement, noncompete agreement or confidentiality agreement with any other person or entity and (iii) upon the execution and delivery of this Agreement by the Company, this Agreement shall be the valid and binding obligation of Employee, enforceable in accordance with its terms. Employee hereby acknowledges and represents that he or she has had the opportunity to consult with independent legal counsel regarding his or her rights and obligations under this Agreement and that he or she fully understands the terms and conditions contained herein.

Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. In the event that any ruling of any court or governmental authority calls into question the validity of any portion of this Agreement, the parties hereto shall consult with each other concerning such matters and shall negotiate in good faith a modification to this Agreement which would obviate any such questions as to validity while preserving, to the extent possible, the intent of the parties and the economic and other benefits of this Agreement and the portion thereof whose validity is called into question.

Each party hereto submits to the co-exclusive jurisdiction of the United States District Court for Massachusetts, and of any Massachusetts state court sitting in Boston, Massachusetts over any lawsuit under this Agreement and waives any objection based on venue or forum non conveniens with respect to any action instituted therein.
