            DESCRIPTION OF SS&C TECHNOLOGIES, INC. ("SS&C") EXECUTIVE
                 OFFICER AND DIRECTOR COMPENSATION ARRANGEMENTS

Executive Compensation Program

      The objectives of SS&C's executive compensation program are to:

      - Attract and retain key executives critical to SS&C's long-term success;

      - Align the interests of executive officers with the interests of
      stockholders and SS&C's success; and

      - Recognize and reward individual performance and responsibility.

      General. SS&C's executive compensation program consists of base salary,
short-term incentive compensation in the form of cash bonuses and long-term
incentive compensation in the form of stock options. In addition, executive
officers are entitled to participate in benefit programs that are available
generally to SS&C employees. These benefit programs include medical benefits,
the employee stock purchase plan and the 401(k) profit sharing plan and trust.

      For 2004, SS&C's management recommended the executive compensation
packages, subject to approval and oversight by the Compensation Committee of
SS&C's Board. On March 11, 2005, the Compensation Committee ratified and
approved the increased annual salaries of Messrs. Pedonti and Whitman set out
below, effective as of March 1, 2005. The base compensation figure for Mr. Milne
is based on the pound-dollar exchange rate as of March 8, 2005.

      Short-Term Incentive Compensation. Under SS&C's senior officer short-term
incentive program, the Compensation Committee has discretionary authority to
award cash bonuses to individual executive officers. The Compensation Committee
believes the short-term incentive program provides significant incentive to
SS&C's executive officers because it enables the Compensation Committee to
reward outstanding individual achievement. The total amount of funds available
for annual bonuses to executive officers and other employees in the incentive
program is tied to SS&C's overall financial performance. On March 11, 2005, the
Compensation Committee elected to award the following bonuses to SS&C's
executive officers for services rendered during 2004:

      Long-Term Incentive Compensation. SS&C provides long-term incentives to
its executive officers and key employees in the form of stock options. The
objectives of this program are to align executive and stockholder long-term
interests by creating a strong and direct link between executive compensation
and stockholder return, and to enable executives to develop and maintain a
significant, long-term stock

<PAGE>

ownership position in the common stock. Stock options are granted generally at
the fair market value of the common stock at the time the option is granted.
Accordingly, these stock options will only have value if SS&C's stock price
increases above the fair market value of the common stock at the time the
options were granted. In selecting executives eligible to receive option grants
and determining the amount and frequency of such grants, the Compensation
Committee evaluates a variety of factors, including (1) the job level of the
executive and (2) past, current and prospective service to SS&C rendered, or to
be rendered, by the executive. During 2004, SS&C granted options to purchase an
aggregate of 50,000 shares of common stock to SS&C's executive officers.

Director Compensation Program

Under a revised director compensation program recommended by the Compensation
Committee and adopted by the Board on March 11, 2005, each non-employee member
of the Board shall receive (i) an annual payment of $10,000 for service on the
Board, (ii) a payment of $1,000 for each Board meeting attended and (iii) a
payment of $500 for each Committee meeting attended. In addition, the Chairman
of the Audit Committee of the Board shall receive an annual payment of $5,000,
and the Chairman of each other Board Committee shall receive an annual payment
of $2,500. All of the directors are reimbursed for expenses incurred in
connection with their attendance at Board and committee meetings. Non-employee
directors are also awarded non-statutory options under SS&C's 1996 Director
Stock Option Plan. Each eligible director is entitled to receive an option to
purchase shares of common stock upon his or her initial election to the Board
and at each annual meeting of stockholders thereafter, provided that he or she
continues to serve as a director immediately following such annual meeting. Such
option shall be fully vested and shall have an exercise price of the closing
price of the Corporation's common stock on the Nasdaq Stock Market on the date
of grant. On March 11, 2005, the Board of Directors amended the Director Plan to
reduce the initial and annual option grants from 7,500 to 5,000 shares.<PAGE>

      laws, rules, regulations and ordinances applicable thereto, and pursuant
      to a Town of Windsor Building Permit (hereinafter referred to as "Tenant's
      Work"), and shall be done by Tenant's choice of contractor (which shall be
      subject to Landlord's reasonable approval) pursuant to a Stipulated Sum
      AIA Document A101 Standard Form of Agreement Between Tenant and Contractor
      (hereinafter referred to as "General Contractor"). Tenant shall have no
      authority to make any changes to the Build-Out Drawings after approval of
      the same by Landlord and Tenant, whether by change order or otherwise,
      absent Landlord's prior written consent, which consent shall not be

Two Hundred Thirty Nine Thousand One Hundred Thirty Dollars ($239,130.00) shall
be borne by Tenant.

      Tenant shall furnish and install any and all necessary trade fixtures,
equipment and other items necessary for the proper conduct of Tenant's business.
In no event shall Landlord be required to provide or install any trade fixtures

one or more responsible contractors whose labor will work in harmony with other
labor working in the Building and with suppliers of materials for use in
construction in and on the Building, and especially Tenant agrees that it will
not do or permit to be done anything which would cause any labor difficulty in
connection with any construction in the Building,

contractors being on or about the Premises or the Building, and from Tenant's
contractors performing work in the Building or on the Premises.

      All contractors, subcontractors, mechanics, laborers, materialmen, and
others who perform any work, labor or services, or furnish any materials, or
otherwise participate in the labor or services, or furnish any materials, or
otherwise participate in the improvement of the Building shall be and are hereby
given notice that Tenant is not authorized to subject Landlord's interest in the
Building to any claim for mechanics', laborers' and materialmen's liens, and all
persons dealing directly or indirectly with Tenant may not look to the Building
as security for payment. Tenant shall save Landlord harmless from and against
all expenses, liens, claims or damages to either property or person which may or
might arise by reason of the making of any such additions, improvements,
alterations and/or installations.

      Tenant shall be liable to Landlord for any damage to the Building caused

      8. Section 32 of the Lease is amended by adding the following sentence

      10. Notwithstanding anything to the contrary in the Lease, Tenant shall
have the right to install its own exclusive signage within the Lamberton Road
Building lobby entrance, consistent with a first class office building and
similar in design and materials to Tenant's existing signage, subject to
obtaining the Landlord's prior written consent after Landlord's review of the
planned signage, which consent shall not be unreasonably withheld or delayed.
All costs associated with said signage (including without limitation all
permitting costs) shall be at the Tenant's sole expense.

      11. Provided Tenant is not in default of its obligations hereunder, beyond
any applicable cure period, and subject to a right of first refusal in favor of
Milliman & Robertson, as presently exists under its lease, Landlord shall
provide Tenant with written notice (the "Right of First Offer Notice") for the
approximately 11,147 square feet of rentable area on the second floor of the
I-91 side of the Building should said space become available for lease.
Landlord's Right of First Offer Notice to Tenant shall set forth the premises'
square footage, the availability date, the term of occupancy (which term shall
be coterminous with the term of this lease as it may be extended), the rent, the
base years for the purpose of Tax and Operating Cost Excess, and the tenant
improvements to be performed by Landlord, if any. The terms and conditions
contained in the Right of First Offer Notice shall reflect Landlord's good faith
determination of the then current fair market rental terms available for
comparable premises in the Building to new tenants. Tenant shall have fifteen
(15) days following receipt of the Right of First Offer Notice to accept said
space on the terms and conditions offered, and if Tenant shall fail to accept
the Offer within said fifteen (15) day period, Tenant shall have waived its
right to the space and shall have no further right pursuant to this Section 11
to the space offered for the remainder of the term of this Lease, as it may be
extended. In the event Tenant accepts the offer of any space pursuant to this
Section 11, Landlord and Tenant shall execute an amendment to this lease,
setting forth the terms and conditions for the lease by Tenant of the space so
acquired.

      12. Except as herein provided, all other terms and conditions of the Lease
are hereby ratified and confirmed, and shall remain in full force and effect.
