Attention: Kazuhiro Nishihata

Senior Vice President

Dear Mr. Nishihata:

You have requested information regarding Intelligroup, Inc. and its subsidiaries (the “Company”, “us” or “we”) in connection with your consideration of the possible acquisition of the Company (a “Possible Transaction”). In consideration of our furnishing you with the Evaluation Materials (as defined below) you agree as follows:

Confidentiality of Evaluation Materials

You will treat confidentially any information (whether written or oral) that either we or our financial advisor, Credit Suisse Securities (USA) LLC (“Credit Suisse”), or our other representatives furnish to you in connection with a Possible Transaction involving the Company, together with analyses, compilations, studies or other documents prepared by you, or by your representatives (as defined hereinafter) which contain or otherwise reflect such information or your review of, or interest in, the Company (collectively, the “Evaluation Materials”). You recognize and acknowledge the competitive value of the Evaluation Materials and the damage that could result to the Company of the Evaluation Materials were used or disclosed except as authorized by this agreement.

The term “Evaluation Materials” includes information furnished to you orally or in writing (whatever the form or storage medium) or gathered by inspection, and regardless of whether such information is specifically identified as “confidential”. The term “Evaluation Materials” does not include information which (i) is or becomes generally available to the public other than as a result of a disclosure by you or your representatives, (ii) was or becomes available to you on a non-confidential basis from a source other than the Company or its representatives, provided that to your knowledge, after due inquiry, such source is not prohibited from disclosing such information to you by a contractual, legal or fiduciary obligation to the Company or its representatives, or (iii) is independently developed by you without violating your obligations hereunder.

Use of Evaluation Materials

You will not use any of the Evaluation Materials for any purpose other than the exclusive purpose of evaluating a Possible Transaction. You and your representatives will keep the Evaluation Materials completely confidential; provided, however, that (i) such information may only be disclosed to those of your directors, officers, employees, affiliates, agents,representatives (including attorneys, accountants and financial advisors), lenders and other sources of debt financing (collectively, “your representatives”) who need to know such information for the purpose of evaluating a Possible Transaction between you and the Company (it being understood that your representatives shall be informed by you of the confidential nature of such information and shall be directed by you, and shall each expressly agree, to treat such information confidential in accordance with this agreement) and (ii) any other disclosure of such information may only be made if the Company consents in writing prior to any such disclosure. Without limiting the generality of the foregoing, in the event that a Possible Transaction is not consummated, neither you nor your representatives shall use any of the Evaluation Materials for any purpose. You will be responsible for any breach of this agreement by you or your representatives.

1

In the event that you or any of your representatives receive a request or are required (by deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar process) to disclose all or any part of the Evaluation Materials, you or your representatives, as the case may be, agree to (i) immediately notify the Company of the existence, terms and circumstances surrounding such request, (ii) consult with the Company on the advisability of taking legally available steps to resist or narrow such request and (iii) assist the Company in seeking a protective order or other appropriate remedy. In the event that such protective order or other remedy is not obtained or that the Company waives compliance with the provisions hereof, (i) you or your representatives, as the case may be, may disclose to any tribunal only that portion of the Evaluation Materials which you are advised by counsel is legally required to be disclosed, and shall exercise your best efforts to obtain assurance that confidential treatment will be accorded such Evaluation Materials and (ii) you shall not be liable for such disclosure unless disclosure to any such tribunal was caused by or resulted from a previous disclosure by you or your representatives not permitted by this agreement.

Non-Disclosure

The disclosure of your possible interest in purchasing the Company could have a material adverse effect on the Company’s business if for any reason an agreement of purchase and sale is not consummated or a disclosure is made prior to the closing of a Possible Transaction. We also acknowledge that Company, Credit Suisse and our other representatives are bound by this non-disclosure policy. Accordingly, unless required by applicable law or regulatory authority, we both agree that prior to the closing of a Possible Transaction, without the prior written consent of you and the Company, we both will not, and we both will direct our representatives not to, disclose to any person the fact that discussions or negotiations are taking place concerning a possible transaction between you and the Company or any of the terms, conditions or other facts with respect to any such Possible Transaction, including the status thereof. The term “person” as used in this agreement shall be broadly interpreted to include, without limitation, any corporation, the Company, governmental agency or body, stock exchange, partnership, association or individual.

Return of Documents

Upon the Company’s request, you shall promptly deliver to the Company all written Evaluation Materials and destroy all copies of Evaluation Materials and any other written materials without retaining, in whole or in part, any copies, extracts or other reproductions (whatever the form or storage medium) of such materials, and shall certify the destruction of such materials in writing to the Company.

No Unauthorized Contact or Solicitation

During the course of your evaluation, all inquiries and other communications are to be made directly to Credit Suisse or employees or representatives of the Company specified by Credit Suissee. Accordingly, you agree not to directly or indirectly contact communicate with any executive or other employee of the Company concerning a Possible Transaction, or to seek any information in connection therewith from such person, without the express written consent of Credit Suisse. You also agree not to discuss with or offer to any third party an equity participation in a Possible Transaction or any other form of joint acquisition by you and such third party without the prior written consent of Credit Suissee.

Without the Company’s prior written consent, you will not for a period of two years from the date of this agreement directly or indirectly solicit for employment any person who is now employed by the Company (or whose activities are dedicated to the Company) in an executive or management level position or otherwise considered by the Company to be a key employee.

Only those representations or warranties that are made to a purchaser in a definitive sale agreement for the Company (“Sale Agreement”) when, as, and if it is executed, and subject to such limitations and restrictions as may be specified in such Sale Agreement, will have any legal effect.

You further understand and agree that (i) the Company and Credit Suisse shall be free to conduct the process for the Company’s sale as they in their sole discretion shall determine (including, without limitation, negotiating with any of the prospective buyers and entering into a Sale Agreement without prior notice to you or to any other person), (ii) any procedures relating to such sale may be changed at any time without notice to you or any other person and (iii) you shall not have any claims whatsoever against the Company, Credit Suisse or any of their respective directors, officers, employees, stockholders, owners, affiliates, agents or representatives arising out of or relating to the sale of the Company.

Legal Remedy

You understand and agree that money damages would not be a sufficient remedy for any breach of this agreement by you or your representatives and that the Company will be entitled to specific performance and injunctive relief as remedies for any such breach. Such remedies shall not be deemed to be the exclusive remedies for a breach of this agreement by you or your representatives but shall be in addition to all other remedies available at law or equity.

The parties understand and agree that no failure of delay by the other party in exercising any right, power or privilege under this agreement shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or future exercise of any right, power or privilege hereunder.
