	 	Re:	Separation from Employment 

 Dear Andrew: 
 This letter confirms our agreement concerning your resignation from employment with InterSearch Group, Inc. (the “Company”), which was effective
September 26, 2007 (the “Separation Date”). This letter confirms the details of your separation and describes the severance benefits that the Company is offering to you. 
 1. Separation Details. As of the date of this letter agreement (the “Agreement”), you have been paid all outstanding compensation and
any accrued, but unused, vacation time. You are eligible to convert your medical insurance coverage under COBRA, and will receive information from our plan administrator describing this conversion election. If you seek reimbursement of any business
expenses, you agree to submit your final expense reimbursement statement within the next ten (10) days, along with receipts or other supporting documentation. The Company will reimburse valid business expenses in accordance with its standard
expense reimbursement policies. 
 2. Severance Payments and Benefits. In exchange for the transitional assistance, general release of
claims, and other agreements contained in this letter, the Company will pay you severance in the amount of One Hundred and Eighty Thousand Dollars ($180,000), less applicable tax withholdings (“Severance Pay”). The Severance Pay will be
paid in equal installments, less applicable withholdings (the “Installment Payments”), on the Company’s regular payroll dates over a period of twelve months (the “Severance Period”) following your acceptance of this
Agreement in accordance with Paragraph 13 below. In addition, if you elect to convert your health coverage under COBRA, the Company will pay the COBRA premiums for you and your qualified dependents during the Severance Period. Except for the
separation terms proposed in this Agreement, you will not be entitled to any compensation, benefits or other perquisites of employment after the Separation Date. In the event you breach any of your obligations under this Agreement, in addition to
any other remedy available by law, all payments and benefits under this Agreement shall immediately cease. 
 3. Transitional
Assistance. Your receipt of the foregoing severance payments and benefits is conditioned upon your successful completion, as reasonably determined by the Company’s Chief Executive Officer of a Transitional Project List and your continued
availability to respond to questions regarding information included on the Transitional Project List during the Severance Period. The Company acknowledges that the Transitional Project List has been received and is acceptable and covenants that
questions regarding the Transitional Project List will not exceed the greater of (a) one (1) hour per week or (b) fifty (50) hours cumulative during

the Severance Period. You acknowledge and agree that you prepared the Transitional Project List and will respond to questions regarding the Transitional
Project List as an independent contractor, and not an agent, common law employee, or representative of the Company. Nothing in this Agreement shall be interpreted or construed as creating or establishing an employment relationship between you and
the Company during the Severance Period, and you shall not be entitled to any benefits awarded the Company’s employees. The severance payments and benefits under this Agreement shall be your sole and exclusive compensation for these
transitional services. 
 4. General Release of Claims. In exchange for the
foregoing payments and benefits, you completely release the Company, its affiliated, related, parent or subsidiary entities, and its and their present and former directors, officers, and employees (the “Released Parties”) from any and all
claims you may now have or have ever had against any of them, including, but not limited to, any claims arising under Title VII of the Civil Rights Act of 1964, the California Fair Employment and Housing Act, the Age Discrimination in
Employment Act (“ADEA”), or any other claims for violation of any federal, state, or municipal laws, and any and all claims for attorneys’ fees and costs (the “Released Claims”).1 The parties intend for this release to be enforced to the fullest extent permitted by law. You understand that you are not waiving any right or claim that
cannot be waived as a matter of law, such as workers’ compensation or unemployment insurance benefits. You agree not to file or initiate any lawsuit concerning the Released Claims. You understand that this paragraph does not prevent you from
filing a charge with or participating in an investigation by a governmental administrative agency; provided, however, that you hereby waive any right to receive any monetary award resulting from such a charge or investigation. 
 5. Equity Agreement. During the Severance Period, you shall agree to be subject to the following limitations on the transfer or disposition of any
shares of stock of the Company then owned by you: 
  

	 	a.	Volume: You shall sell no more than twenty percent (20%) of the average daily trading volume of the Company’s stock on the Principal Market for the ten
(10) consecutive trading days immediately preceding the date of the sale(s). 

  

	 	b.	Price: The sale price of any share of common stock sold by you shall not be at a price that is ten percent (10%) lower than the average of the Adjusted Closing Price for
the ten (10) consecutive trading days immediately preceding the date of the sale(s); provided, however, no share of common stock shall be sold at a price less than one dollar ($1.00). 

  

	1	You agree that because this release specifically covers known and unknown claims, you waive your rights under Section 1542 of the California Civil Code, or under any comparable
law of any other jurisdiction. Section 1542 states: “A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her
must have materially affected his or her settlement with the debtor.”

 “Adjusted Closing Price” means, for any security as of any date, the adjusted
closing price for such security on the Principal Market during the period beginning at 9:30:01 a.m., New York Time (or such other time as the Principal Market publicly announces is the official open of trading), and ending at 4:00:00 p.m., New York
Time (or such other time as the Principal Market publicly announces is the official close of trading) as reported by Yahoo! Finance. 
 “Principal Market” means the American Stock Exchange or, if the American Stock Exchange is not the principal trading market for the Company’s common stock, then on the principal securities exchange or securities market
on which the common stock is then traded 
 6. Market “Stand-Off” Agreement. You agree that you shall not, to the extent
requested during the Severance Period by the Company or an underwriter of securities of the Company, sell or otherwise transfer or dispose of any shares of stock of the Company then beneficially owned by you (as defined in Section 13 of the
Securities Act) for (i) up to 180 days following the date of the final prospectus in connection with an initial public offering by the Company of its securities and (ii) up to 90 days following the date of the final prospectus in
connection with any registration statement of the Company filed under the Securities Act within twenty-four (24) months of the closing date of an initial public offering by the Company; provided, however, that the foregoing shall not apply to
shares held by you that are sold pursuant to such registration statement. In addition, you agree to execute and deliver as requested by the lead underwriter, an agreement, in such lead underwriter’s standard form, reflecting the foregoing. The
provisions of this paragraph are referred to herein as the “Market Stand-Off Agreement” and shall be binding upon any transferee or assignee of any securities of the Company owned by you. You further agree that the if the Market Stand-Off
Agreement has been triggered during the Severance Period by a request of the Company or an underwriter of securities of the Company pursuant to the first or second sentence of this paragraph, you shall remain subject to the terms of such Market
Stand-Off Agreement for the applicable period following the Severance Period, as described above (the “Remainder Period”). In furtherance of the foregoing, you acknowledge that the Company and its transfer agent and registrar are hereby
authorized to decline to make any transfer of securities of the Company if such transfer would constitute a violation or breach of this Agreement. In consideration for any limitations that may be imposed upon you during the Remainder Period, at the
sole determination of the Company, you shall have the right during the Remainder Period to either (a) continue to sell shares of stock of the Company then owned by you in accordance with the limitations set forth in Paragraph 5 hereof or
(b) receive additional cash payments, each equal to the amount of an Installment Payment, which additional payments shall be paid on the Company’s regular payroll dates.

 7. Compliance with Confidentiality and Insider Trading Policy. During the Ninety (90) day
period following the termination of your employment with the Company (the “Termination Period”), you shall continue to comply with the InterSearch Group, Inc. Confidentiality and Insider Trading Policy dated March 15, 2006, as
amended June 20, 2007 (the “Insider Trading Policy”). For purposes of the Insider Trading Policy, you shall remain subject during the Termination Period to the restrictions applicable to Covered Persons. 
 8. Non-Solicitation. In addition to your continuing obligations under your Noncompete Agreement dated December 10, 2004 and signed in
connection with the merger of Walnut Ventures, Inc. and the Company (the “Noncompete Agreement”) and your Employee Proprietary Information and Inventions Assignment Agreement dated January 19, 2007 (the “EPIAA”), you
agree that during the Severance Period and for a period of one (1) year thereafter, you shall not directly or indirectly (i) solicit, induce, recruit or encourage any person employed by the Company to terminate his or her employment, or
(ii) divert or attempt to divert from the Company any business with any customer, client, member, business partner or supplier about which you obtained confidential information during your employment with the Company, by using the
Company’s trade secrets or by otherwise engaging in conduct that amounts to unfair competition. 
 9. Confidentiality. You
understand and agree that this letter shall be maintained in strict confidence, and that you shall not disclose any of its terms to another person, except to your legal counsel, tax advisors or immediate family, unless required by law. You further
agree not to make or publish, either orally or in writing, any disparaging statement about the Released Parties. 
 10.
Return of Company Property. Within five (5) business days of the date of your acceptance of this Agreement, you confirm that you will return all Company materials in your possession or control, including keys and any computer equipment. To
the extent you need such materials to perform your transitional services they will be provided separately at that time. 
 11.
Dispute Resolution. Any and all disputes arising out of the terms of this Agreement, their interpretation, or any of the Released Claims, shall be resolved by final binding arbitration in San Francisco, California, under the Commercial Rules
of the American Arbitration Association. Either party may bring an action in court to compel arbitration under this Agreement, to enforce an arbitration award, or to obtain temporary injunctive relief pending a judgment. Otherwise, neither party
shall initiate or prosecute any legal action against the other. The prevailing party in the arbitration shall be entitled to recover its attorneys’ fees and costs (at reasonable, regular hourly rates), in addition to any other relief to which
it may be entitled by law. 
 12. Entire Agreement. This Agreement contains all of our agreements and understandings and fully
supersedes any prior agreements or understandings that we may have had regarding your employment with the Company or its termination, with the exception of the EPIAA and the

Noncompete Agreement. This Agreement is governed by California law and may be amended only in a written document signed by both of us. If any term in this
Agreement is unenforceable, the remainder of this Agreement will remain enforceable. You acknowledge that the payments and benefits described above exceed any amount to which you otherwise are entitled under the Company’s policies and
practices. 
 13. Acceptance. To accept this Agreement, please sign below and return this letter to me on or before
October 31, 2007. 
 If you have any questions, please feel free to call me. We wish you the best in your future endeavors.

 AMENDMENT TO SEPARATION AGREEMENTVoting Agreement between Ansys and Zoltan Cendes

 Exhibit 10.1 
 VOTING AGREEMENT 
 THIS VOTING AGREEMENT (“Agreement”), dated as of
March 31, 2008, is made by and between ANSYS, Inc., a Delaware corporation (the “Buyer”), and the undersigned holder (the “Stockholder”) of shares (the “Shares”) of common stock, par value
$0.01 per share, of Ansoft Corporation, a Delaware corporation (the “Seller”). 
 WHEREAS, concurrently with the
execution of this Agreement, Buyer, Evgeni, Inc., a Delaware corporation and a wholly owned Subsidiary of Buyer (“Merger Sub”), Sidney LLC, a single member Delaware limited liability company and wholly owned subsidiary of Buyer
(“Merger LLC”), and Seller have entered into an Agreement and Plan of Merger, dated of even date herewith (as such agreement may be subsequently amended or modified, the “Agreement and Plan of Merger”), providing
for the merger (the “Merger”) of Merger Sub with and into Seller, with Seller to be the surviving corporation of the Merger, which Merger will be followed immediately by a merger of the entity surviving the Merger with and into
Merger LLC (the “Upstream Merger”), with the Merger LLC to be the surviving entity in the Upstream Merger; 
 WHEREAS, the Stockholder beneficially owns (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) and has sole or shared voting power with respect to the number of Shares, and holds stock options or other
rights to acquire the number of Shares indicated opposite the Stockholder’s name on Schedule 1 attached hereto; 
 WHEREAS, it is a condition to the entrance into the Agreement and Plan of Merger that the Stockholder execute and deliver this Agreement on a date even herewith; and 
 WHEREAS, all capitalized terms used in this Agreement without definition herein shall have the meanings ascribed to them in the Agreement and Plan
of Merger. 
 NOW, THEREFORE, in consideration of, and as a condition to, Buyer entering into the Agreement and Plan of Merger and
proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by Buyer in connection therewith, the Stockholder and Buyer agree as follows: 
 1. Agreement to Vote Shares. The Stockholder agrees that, from and after the date hereof until the Expiration Date (as defined below), at any
meeting of the stockholders of Seller or any adjournment thereof, or in connection with any written consent of the stockholders of Seller, with respect to the Merger, the Agreement and Plan of Merger, or any Acquisition Proposal, the Stockholder
shall: 
 (a) appear in person or by proxy at such meeting or otherwise cause the Shares to be counted as present thereat for purposes of
calculating a quorum; 
 (b) vote (or cause to be voted), or deliver a written consent (or cause a consent to be delivered) covering all of
the Shares that such Stockholder shall be entitled to so vote, whether such Shares are beneficially owned by such Stockholder on the date of this Agreement or are subsequently acquired, (i) in favor of adoption and approval of the Agreement and
Plan of Merger and all other transactions contemplated by the Agreement and Plan of Merger as to 

 
which stockholders of Seller are called upon to vote or consent; and (ii) against any Acquisition Proposal, or any agreement or transaction providing
for the consummation of a transaction contemplated by any Acquisition Proposal. 
 2. Expiration Date. As used in this Agreement, the
term “Expiration Date” shall mean the earlier to occur of (a) the Effective Time, (b) the termination of the Agreement and Plan of Merger pursuant to Article VIII thereof, or (c) upon mutual written agreement of the
parties to terminate this Agreement. Upon termination or expiration of this Agreement, no party shall have any further obligations or liabilities under this Agreement; provided, however, such termination or expiration shall not relieve any
party from liability for any willful breach of this Agreement prior to termination hereof. 
 3. Agreement to Retain Shares. From and
after the date hereof until the Expiration Date, the Stockholder shall not, except as contemplated by this Agreement or the Agreement and Plan of Merger, directly or indirectly, sell, assign, transfer, or otherwise dispose of (including, without
limitation, by the creation of a Lien (as defined below)), or enter into any contract, option, commitment or other arrangement or understanding with respect to the sale, assignment, transfer, or other disposition of, any Shares owned by the
Stockholder, whether such Shares are held by the Stockholder on the date of this Agreement or are subsequently acquired prior to any meeting of stockholders held prior to the Expiration Date, whether by the exercise of any stock options to acquire
Shares or otherwise. Notwithstanding the foregoing, the Stockholder may make (a) transfers by will or by operation of law, in which case this Agreement shall bind the transferee, (b) transfers in connection with estate and charitable
planning purposes, including transfers to relatives, trusts, and charitable organizations, subject to the transferee agreeing in writing to be bound by the terms of, and perform the obligations of the Stockholder under, this Agreement,
(c) transfers of shares in connection with the exercise of options to purchase 100,000 Shares within 30 days prior to their expiration in accordance with their terms either (i) with a value after payment of any taxes owed as a result of
the transfer, that does not exceed the sum of the option exercise price and minimum withheld tax or (ii) to Seller in a net exercise transaction and (d) as Buyer may otherwise agree in writing in its sole discretion. 
 4. Representations and Warranties of the Stockholder. The Stockholder hereby represents and warrants to Buyer as follows: 
 (a) the Stockholder has the power and the right to enter into and perform the terms of this Agreement; 
 (b) this Agreement (assuming this Agreement constitutes a valid and binding agreement of Buyer) constitutes a valid and binding agreement with respect to
the Stockholder, enforceable against the Stockholder in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to creditors’ rights and general principles of equity;

 (c) except as set forth on Schedule 1, the Stockholder beneficially owns the number of Shares indicated opposite such
Stockholder’s name on Schedule 1, free and clear of any liens, claims, charges or other encumbrances or restrictions (“Liens”), and has sole or shared, and otherwise unrestricted, voting power with respect to such
Shares; and 
  

 2 

 (d) the execution and delivery of this Agreement by the Stockholder does not, and the performance by the
Stockholder of his or her obligations hereunder and the consummation by the Stockholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other
obligation or any order, arbitration award, judgment or decree to which the Stockholder is a party or by which the Stockholder is bound, or any statute, rule or regulation to which the Stockholder is subject or, in the event that the Stockholder is
a corporation, partnership, trust or other entity, any bylaw or other organizational document of the Stockholder. 
 5. Irrevocable
Proxy. Subject to the last sentence of this Section 5, by execution of this Agreement, the Stockholder does hereby appoint Buyer with full power of substitution and re-substitution, as the Stockholder’s true and lawful attorney
and irrevocable proxy, to the fullest extent of the undersigned’s rights with respect to the Shares, to vote, if the Stockholder is unable to perform his or her obligations under this Agreement, each of such Shares solely with respect to, and
in a manner consistent with, the matters set forth in Section 1 hereof. The Stockholder intends this proxy to be irrevocable and coupled with an interest hereunder until the Expiration Date and hereby revokes any proxy previously granted
by the Stockholder with respect to the Shares. Notwithstanding anything contained herein to the contrary, this irrevocable proxy shall automatically terminate upon the Expiration Date of this Agreement. 
 6. Specific Enforcement. The Stockholder has signed this Agreement intending to be legally bound thereby. The Stockholder expressly agrees that
this Agreement shall be specifically enforceable in any court of competent jurisdiction in accordance with its terms against the Stockholder. 
 7. Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed an original but all of which together shall constitute one and the same instrument. 
 8. No Waivers. No waivers of any breach of this Agreement extended by Buyer to the Stockholder shall be construed as a waiver of any rights or
remedies of Buyer with respect to any other stockholder of Seller who has executed an agreement substantially in the form of this Agreement with respect to shares of Seller Common Stock held or subsequently held by such stockholder or with respect
to any subsequent breach of the Stockholder or any other such stockholder of Seller. No waiver of any provisions hereof by either party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a
continuing waiver of any provision hereof by such party. 
 9. Governing Law. This Agreement shall be governed by the laws of the
State of Delaware, without giving effect to the principles of conflicts of laws thereof. If any provision hereof is deemed unenforceable, the enforceability of the other provisions hereof shall not be affected. 
 10. Capacity as Stockholder. The Stockholder signs this Agreement solely in the Stockholder’s capacity as a stockholder of Seller, and not in
the Stockholder’s capacity as a director, officer or employee of Seller or any of its Subsidiaries or in the Stockholder’s capacity as a trustee or fiduciary of any ERISA plan or trust. Notwithstanding anything herein to the 

  

 3 

 
contrary, nothing herein shall in any way restrict a director and/or officer of Seller in the exercise of his or her fiduciary duties consistent with the
terms of the Agreement and Plan of Merger as a director and/or officer of Seller or in his or her capacity as a trustee or fiduciary of any ERISA plan or trust or prevent or be construed to create any obligation on the part of any director and/or
officer of Seller or any trustee or fiduciary of any ERISA plan or trust from taking any action in his or her capacity as a director of Seller. 
 11. No Agreement Until Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or
understanding between the parties hereto unless and until (a) the Board of Directors of Seller has approved, for purposes of any applicable anti-takeover laws and regulations, and any applicable provision of the Seller Charter, the possible
acquisition of the Shares by Buyer and its Subsidiaries pursuant to the Agreement and Plan of Merger, (b) the Agreement and Plan of Merger is executed by all parties thereto, and (c) this Agreement is executed by all parties hereto.

 12. Entire Agreement; Amendment. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with
respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived,
except by an instrument in writing signed by each party hereto. 
 13. Notices. All notices and other communications hereunder shall
