EXHIBIT A

CONFIDENTIAL INFORMATION

In connection with your providing certain products and/or services to Syntel INC
(“SYNTEL”) and/or on behalf of SYNTEL, you will have access to information
concerning SYNTEL and SYNTEL’s clients. As a condition to your being given
access to such information, you agree to treat any information concerning SYNTEL
and/or SYNTEL’s clients (whether prepared by SYNTEL, its advisors or otherwise)
which is furnished to you by or on behalf of SYNTEL and/or SYNTEL’s clients
(herein collectively referred to as the “Confidential Information”) in
accordance with the provisions of this letter and to take or abstain from taking
certain other actions herein set forth. The term “Confidential Information” does
not include information which (i) is already in your possession, or (ii) becomes
generally available to the public other than as a result of a disclosure by you
or your directors, officers, employees, agents or advisors, or (iii) becomes
available to you on a non-confidential basis from a source other than SYNTEL
and/or SYNTEL’s clients.

You hereby agree that the Confidential Information will be used solely for the
purpose of providing certain products and/or services to and/or on behalf of
SYNTEL, and that such information will be kept confidential by you and your
advisors; provided, however, that (i) any of such information may be disclosed
to your directors, officers and employees and representatives of your advisors
who need to know such information for the purpose of providing such services to
and/or on behalf of SYNTEL (it being understood that such directors, officers,
employees and representatives shall be informed by you of the confidential
nature of such information and shall be directed by you to treat such
information confidentially), and (ii) any disclosure of such information may be
made to which SYNTEL consents in writing.

Notwithstanding the foregoing, if you or any of your representatives are
required (by oral question or request for information or documents in legal
proceedings or similar process) to disclose any Confidential Information, you
will promptly notify SYNTEL of such requirement so that SYNTEL may seek an
appropriate protective order and/or waive your compliance with the provisions of
this Agreement. If, in the absence of a protective order or the receipt of a
waiver hereunder, you or any of your representatives is nonetheless, in the
reasonable written opinion of counsel, compelled to disclose Confidential
Information to any tribunal or else stand liable for contempt or suffer other
censure or penalty, you or your representatives, after notice to SYNTEL, may
disclose such Confidential Information to such tribunal. You or your
representatives shall not be liable for the disclosure of Confidential
Information hereunder to such tribunal compelling such disclosure unless such
disclosure to such tribunal was caused by or resulted from a previous disclosure
by you or your representatives not permitted by this Agreement.

You agree that the furnishing of Confidential Information neither grants nor
implies any license under any trademark, patent, copyright, methodology,
intellectual property or process right, or any other property right nor does the
furnishing of Confidential Information constitute an inducement of any kind, or
any representation, warranty, assurance, or guarantee with respect to the no
infringement of trademarks, patents, copyrights, methodologies, intellectual
property rights or processes, or any other property rights of third persons or
of SYNTEL. You agree to promptly redeliver to SYNTEL, upon request, all
Confidential Information on any tangible media and that you will not retain any
copies, extracts or other reproductions in whole or in part of such material.
You further agree that breach of this confidentiality letter agreement could
cause irreparable harm to SYNTEL and that SYNTEL shall be entitled to any and
all injunctive relief, as well as monetary damages, including reasonable
attorney fees, for such breach.

You agree that this confidentiality letter agreement contains the entire
agreement between you and SYNTEL regarding Confidential Information and SYNTEL
shall not be bound by any other different, additional, or further agreements or
understandings except as consented to in writing by SYNTEL. This confidentiality
letter agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns. No amendment hereof shall be
effective unless contained in a written instrument signed by the parties hereto.
No delay or omission by either party to exercise any right or power under this
Agreement shall impair such right or power or be construed to be a waiver
thereof. A waiver by either party of any of the covenants to be performed by the
other party or of any breach shall not be construed to be a waiver of any
succeeding breach or of any other covenant. If any provision of this
confidentiality letter

--------------------------------------------------------------------------------

agreement is declared invalid, such provision shall be deemed severable from the
remaining provisions of the confidentiality letter agreement, which shall remain
in full force and effect. All rights and remedies provided for in this
confidentiality letter agreement shall be cumulative and in addition to and not
in lieu of any other rights or remedies available to either party at law, in
equity, or otherwise. This letter shall be governed by, and construed in
accordance with, the laws of the State of Michigan.
