Dear
Mark:

Re:
Autonomy Board of Directors

I
am pleased to confirm the terms of your appointment as a non-executive Director of Autonomy Corporation plc (the "Company"). The Board was
extremely impressed with your business and finance experience, and look forward to the expertise and diversity of opinions you will bring to the Board. 

	1.
	Duties.    You shall be expected to attend meetings of the Board, as well as General Meetings of the shareholders upon
request. We expect that you shall be required to serve on the Audit Committee of the Board. In addition, you shall exercise such functions as are consistent with your appointment and which are
delegated to you from time to time by the Board.

	2.
	Company Information.    You shall be supplied with all information (including financial information) which you may reasonably
require in order to carry out your duties, and such information shall be provided sufficiently in advance to enable you to give it proper consideration prior to any decision which may have to be made
with respect to such information.

	3.
	Fees.    Your Directors' fees shall be US$25,000 per annum which shall accrue from day to day and shall be payable in equal
quarterly installments in arrears and shall be subject to all deductions as are required by law. Those fees shall be reviewed by the Remuneration Committee of the Board at its discretion. You shall
not be eligible for any other benefits except as specified herein.

	4.
	Expenses.    You shall be reimbursed for all reasonable out of pocket expenses (including, if necessary, the cost of air fares
and hotel accommodations in respect of your attendance at Board or General meetings of the shareholders of the Company) properly incurred by you on Company business. Claims for reimbursement shall be
paid within 30 days of submission to the Board and shou1d be accompanied by evidence of such expenditures in accordance with Company policy.

	5.
	Liability Insurance.    The Company maintains Directors' and Officers' Liability Insurance which would cover you as a Director
of the company.

	6.
	Confidentiality Obligation.    You agree to the Company's standard confidentiality obligations during your appointment,
attached hereto as Appendix A.

	7.
	Code of Conduct.    During your appointment you shall comply, and shall procure, so far as you are able, that your spouse and
infant children (if any) or any trust in which you or your wife may be concerned or interested as trustee or beneficiary, comply with any code of conduct relating to securities transactions by
directors and specified employees adopted by the Company from time to time.

	8.
	Articles.    Your appointment is subject to the Articles of Association or the Company. When that appointment ends and for
whatever reason, it is agreed that you shall not be entitled to any further compensation and you agree to resign from your office as a Director. Should you fail to do so, you agree that the Board can
appoint someone in your name and on your behalf to sign any

applicable
documents and to take such other steps as may be necessary to give effect to your resignation. 

	9.
	Termination by Company.    The Company may terminate your appointment without notice:

	(a)
	if
you commit any serious or repeated breach of your obligations or are guilty of any serious default or misconduct in connection with the Autonomy Group's business or of conduct
which adversely affects the reputation or standing of the Autonomy Group or you;

	(b)
	if
you resign as a Director of the Company for any reason or are prohibited by law from holding office as a Director; or

	(c)
	if
you are unable to perform your duties by reason of ill health for a period in excess of 90 days (whether or not consecutive) in any period of 52 consecutive weeks.

	10.
	Termination for Convenience.    Either party may terminate your appointment by giving the other not less than three months'
prior written notice.

	11.
	Representation.    You represent to the Company that your appointment as Director of the company (and the performance of your
duties in accordance with such appointment) shall not violate any existing or future agreements you may have with any other person or entity.

	12.
	Certain Definitions.    In this letter "Autonomy Group" shall mean the
Company and any company which is a subsidiary of the Company or any company which is the ultimate holding company of the Company, where "holding company" and "subsidiary" have the meanings ascribed to
them by Section 736 of the Companies Act of 1985.

	13.
	Miscellaneous.    This agreement supersedes any prior agreements, representations or promises of any kind, whether written,
oral, express or implied, between you and the Autonomy Group, and constitutes the full, complete and exclusive agreement between you and the Company with respect to the subject matter of this
agreement. This agreement cannot be changed unless in writing, signed by you and a duly authorized Director of the Company. If any term of this agreement is held to be invalid, void or unenforceable,
such void or unenforceable portion(s) shall be limited or excluded from this agreement to the minimum extent required so that this agreement shall remain in full force and effect and in accordance
with its terms; and, the parties shall use their best efforts to find an alternative way to achieve the same result. This agreement shall be governed by the laws and statutes of England and Wales and
you agree to submit to the jurisdiction thereof with respect to any claim or action arising under or out of this agreement or the subject matter hereof. 

If
you agree to the terms set forth herein, kindly countersign both copies of this letter to confirm the basis of your appointment with the Company and return one copy to the Company at the address
set forth on the first page hereof. 

Yours
sincerely, 

/s/

In
no event shall any Shares otherwise vest following the termination of your employment at Autonomy or its parent, subsidiaries or affiliates. 

	5.
	Duties.    Your new duties generally will be in the areas of overseeing Autonomy's sales operations throughout the United
States, but you may be assigned other duties as needed and your duties may change from time to time on reasonable notice, based on the needs of Autonomy and your skills, as determined by Autonomy. You
shall report directly to the Chief Executive Officer of the group in these new duties.

Autonomy without notice, or payment in lieu of notice, in the event of gross misconduct, examples of which are provided in Autonomy's disciplinary rules, or if you commit a 

1

 

material
breach of the terms of your employment such as breach of confidentiality, discipline or security. The disciplinary rules do not form part of this employment letter and may be amended by
Autonomy from time to time. (c) Autonomy shall be entitled to terminate your employment summarily on making you a payment of your basic salary (less tax and other required deductions) in lieu
of notice. (d) Autonomy shall be under no obligation to provide you with work during any period of notice to terminate your employment, whether given by Autonomy or by you. During such period
Autonomy may suspend you from employment, require you to cease carrying out your duties or having any dealings with Autonomy's employees, suppliers, agents, or customers and may exclude you from any
premises of Autonomy. You will continue to receive your salary and all contractual benefits provided by your employment. You agree that you will, if requested to do so, forthwith resign from all
offices held by you in Autonomy or any group companies. During such period of notice you may not be engaged or employed by or take up any office or partnership in any other company, firm or business,
or trade on your own account without the written permission of the Chief Executive Officer of the group. (e) Should you commence employment with another employer prior to the expiration of the
notice period, either given or received, Autonomy will terminate the period of notice and payment of salary effective from the date you commence such other employment. 

	6.
	Waiver.    In connection with, and in consideration for, this promotion and the additional payments and other benefits set
forth herein, each party hereby fully and forever releases, waives, discharges and promises never to assert any claims or causes of action now known against the other, or against Autonomy's parent and
its parent's other subsidiaries and their respective predecessors, successors, subsidiaries, officers, directors, shareholders, agents, employees and assigns, in respect of any matter arising out of
or in connection with your employment by Autonomy or prior to the date hereof including, but not limited to, claims of wrongful discharge, emotional distress, defamation, breach of contract, breach of
