                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT, dated this 24th day of April, 1997 is by and between
Cityscape Corp., a Delaware corporation (hereinafter "Employer") and Gregg L.
Armbrister (hereinafter "Employee").

                                   WITNESSETH:

         WHEREAS, the Company desires to hire and retain the Employee as an
employee to perform certain services for the Company.

         NOW, THEREFORE, in consideration of the mutual covenants contained
herein and on the attached Schedule, and for other good and valuable
consideration the receipt of which is hereby acknowledged, the Company and the
Employee hereby agree as follows:

         1.       EMPLOYMENT OF EXECUTIVE.

         (a) The Company hereby employs the Employee in the capacity and for the
position set forth in Item 1 of the Schedule attached hereto. Employee hereby
accepts such employment with the Company upon the terms and conditions
hereinafter set forth.

         (b) The duties of the Employee shall include the duties and services
described in Item 2 of the Schedule, which duties and services shall at all
times be subject to the direction, approval and control of the Company and shall
include such other duties, as may be assigned by the Board of Directors of the
Company commensurate with the responsibilities normally associated with
Employee's position.

         2.       SERVICES TO BE RENDERED.

         The Employee will devote Employee's full time and efforts to the
business and affairs of the Company and shall not during the term of this
Agreement be engaged in any other businesses; provided that the Employee may
engage in passive investments in businesses in which the Employee does not
participate. Notwithstanding the foregoing, the Employee may retain his
ownership interest in the firm K. M'Kenzie And Associates, Inc., a Georgia
corporation, but shall not take part in the active management of the same while
in the employ of Employer. The
<PAGE>   2
Employee will always use Employee's best efforts to promote the interests of the
Company.

         3.       TERM.

         The term of this Agreement (the "Term") shall commence on May 1, 1997,
and shall continue until April 30, 2001, unless (i) extended by the mutual
agreement of the Company and the Employee or (ii) terminated as hereinafter
provided. Until May 1, 1997, Employee shall serve as a consultant to Employer
under the usual terms and conditions between the parties and Employee shall
devote approximately sixty per cent (60%) to Employer's business pursuits during
this time.

         4.       COMPENSATION.

         (a) The Employee shall receive a salary as set forth on Schedule 3.
Effective May 1, 1997, the salary due and payable under Schedule Item 3 shall be
increased each January by the percentage increase, if any, in the Consumer Price
Index defined in subsection (c) below between November 1996 and November 1997
for the first increase and between November 1997 and November 1998 for the
second increase, and November 1998 and November 1999 for the third increase. The
increases shall be cumulative, that is the base salary upon which a CPI increase
is that which is in effect at the end of each year. In no event shall the salary
be reduced because of a percentage decline in the Consumer Price Index.

         (b) Each January, commencing with January 1998, the Board of Directors
of the Company shall review Employee's performance and the Board of Directors
may, in its sole discretion, elect to increase the salary then paid to Employee;
however, there shall be absolutely no obligation to do so.

         (c) Consumer Price Index shall mean the Index published by the United
States Department of Labor for all Urban Consumers U.S. City Average N.Y., N.J.,
CT. 1982-1984 = 100 or such successor Index as may be published which most

         5.       BENEFITS.

         The employee shall be entitled to participate in the regular pension,
profit sharing, health, disability, and other benefit
<PAGE>   3
programs of the Company in effect from time to time on the same basis that other
senior officers of the Company participate therein. To the extent possible,
without incurring additional expense and without adversely affecting the right
of any other employee, the Company shall endeavor to eliminate or waive any
waiting period with respect to profit sharing and/or pension benefits as well as
health insurance benefits. The Employee shall be entitled, for the term hereof,
to annual vacations to be taken in accordance with the policies of the Company
in effect from time to time for senior officers but in no case less than two (2)
weeks paid vacation for each year while employed beginning on and including the
first year of employment.

         6.       EXPENSES.

         The Company shall reimburse the Employee against appropriate vouchers
or other receipts for business expenses reasonably incurred by Employee in the
performance of Employee's duties pursuant to the terms hereof. In addition, upon
the submission of appropriate vouchers or other receipts, the Company shall
reimburse Employee for gas, tolls, and car phone charges. Employee shall submit
vouchers or other receipts once per calendar month and shall be reimbursed by
Company within thirty (30) days of submission. Expenses shall further include
reimbursement for reasonable monthly car rental or car purchase payments not
exceeding Four Hundred Fifty Dollars ($450).

         7.       DEATH AND DISABILITY.

         In the event of the death of the Employee during the Term, the
Employee's employment hereunder shall automatically terminate. In the vent of
the total disability of the Employee, the Employee's employment hereunder may
terminate at the option of the board of Directors of the Company. For purposes
of this Agreement, "total disability" shall mean the Employee's inability to
perform Employee's regular and customary duties on behalf of the Company for a
period of no less than 120 consecutive days, or any 180 days during an twelve
(12) month period, with such "total disability" being established by a written
certification submitted by the medical doctor agreed to by the Employee and the
Company. In the absence of agreement, the Company and the Employee shall each
nominate a qualified doctor and these two (2) doctors shall select a third
qualified medical doctor, which third doctor shall make the determination as to
total disability. During the aforementioned 120 and 180 day periods, Employee
shall receive his
<PAGE>   4
regular salary less any Company provided disability insurance proceeds Employee
may receive. After the termination of these time periods, no salary will be
payable.

         8.       CAUSE.

         By notice to the Employee, the President or the Board of Directors of
the Company may terminate this Agreement for Cause. As used herein, "Cause"
shall be defined as: (a) the refusal or failure by the Employee to carry out
specific directions of the Board of Directors which are of a material nature and
consistent with Employee's position described in the Schedule, or the refusal or
failure by the Employee to perform a material part of the Employee's duties
hereunder; (b) the commission by the Employee of a breach of any of the
provisions of this Agreement; (c) the commission by the Employee of a fraudulent
or dishonest act in Employee's relations with the Company or any of its
affiliates, or with any customer or business contact of the Company or any of
its affiliates ("dishonest" for these purposes shall mean that Employee
knowingly or recklessly made a material misstatement or omission for Employee's
personal benefits); (d) the conviction of the Employee for any crime involving
an act of moral turpitude; (e) any act of insubordination or the willful failure
to carry out a written directive of the board of Directors which does not
violate the terms of this Agreement; (f) any breach under Sections 9 and 10 of
this Agreement; of (g) the Employee's gross incompetence. Notwithstanding the
foregoing, no "Cause" for termination shall be deemed to exist with respect to
the Employee's acts described in clauses (a) or (b) above, unless the Company
shall have given written notice to the Employee specifying the "Cause" with
reasonable particularity and, within ten (10) business days after such notice,
Employee shall not have cured or eliminated the problem or thing giving rise to
such "Cause"; provided, however, that (i) any periodic breach or continual
breaching after notice and cure of any provision of clauses (a) or (b) above, or
(ii) a repeated breach after notice and cure, of any provisions of clause (a) or
(b) above, involving the same or substantially similar actions or conduct, shall
be grounds for termination for cause without any additional notice from the
Company. The parties hereto agree that three (3) separate instances of a breach
by the Employee of the provisions of this Agreement during the Term shall be
considered periodic, continual or repeated and shall constitute "Cause" within
the meaning of this Section 8.

Employee's employment by the Company, the Employee, both during and after the
Terms, will obtain secret and confidential information concerning the business
of the Company and its affiliates, including, without limitation, financial
information, trade secrets, information concerning the operations, sales,
personnel, suppliers, customers, costs, profits and pricing policies, "know how"

         (b) During the Term and thereafter, the Employee shall exercise all due
and diligent precautions to protect the integrity of the customer lists, mailing

copies thereof) then in Employee's possession or control.

         (c) The Employee agrees that Employee will not at any time, either

<PAGE>   7
which Employee may then possess or have under Employee's control; provided,
however, that Employee shall be entitled to retain copies of such documents
reasonably necessary to document Employee's financial relationship (both past
and future) with the Company.

         (e) The Employee acknowledges that (i) any breach of the provisions of
these Sections 9 and 10 may cause substantial and irreparable harm to the
Company for which the Company would have no adequate remedy at law, and (ii) the
provisions of this Agreement are reasonable and necessary for the protection of
the business of the Company and its affiliates.

         11.      REMEDIES FOR EMPLOYER.

         (a) If Employee commits a breach, or threatens to commit a breach, of
any of the provisions of Sections 9 and 10, the Company shall have the right and
remedy:

                  (i) to have the provisions of this Agreement specifically
                  enforced by any court having equity jurisdiction; and

                  (ii) to require Employee to account for and to pay over to the
                  Company all damages suffered by the Company (including
                  consequential and incidental damages) as a result of any
                  transactions constituting a breach of any of the provisions of
                  Sections 9 and 10, and Employee hereby agrees to account for
                  and pay over such damages to the Company;

         (b) The Employee acknowledges and agrees that the services being
rendered hereunder to the Company are of a special, unique and extraordinary
character and that any such breach or threatened breach may cause substantial
and irreparable injury to the Company and that money damages will not provide an
adequate remedy to the Company. Employee further agrees that the Company in any
such equitable proceeding shall not have to prove irreparable harm. (However, in
a suit for damages, Company shall be required to prove the amount of damages
actually sustained.)

         (c) Each of the rights and remedies enumerated in Section 11(a) shall
be independent of the other, and shall be severally enforceable, and such rights
and remedies shall be in addition to, and not in lieu of any other rights and
remedies available to the
<PAGE>   8
Company under law or equity.

         (d) If any provision of Sections 9 or 10 is held to be unenforceable
because of the scope, duration or area of its applicability, the court making
such determination shall have the power to modify such scope, duration, or area,
or all of them, and such provision or provisions shall then be applicable in
such modified form.

         12.      INDEMNIFICATION.

         (a) The Company hereby agrees to indemnify and hold harmless the
Employee, both during and after the expiration of the Term, from and against any
and all loss or liability including reasonable legal fees and legal
disbursements which the Employee may have to third parties as a result of the
proper performance of Employee's duties hereunder during the Term, to the extent
permitted by the laws of the State of New York. The Employee hereby agrees to
indemnify and hold harmless the Company from any and all loss or liability which
the Company suffers as a result of employee's breach of Employee's obligations
hereunder to the extent permitted by the laws of the State of New York. When the
Company assumes its obligation to indemnify and hold harmless the Employee in
connection with a claim or litigation, its obligation with respect to such claim
or litigation shall be limited to holding the Employee harmless from and against
any judgment or settlement approved by the Company in connection with the claim
or litigation. The Company reserves the right to select counsel of its choosing
to defend the Employee.

         (b) Whenever a claim shall arise for which any party may be or become
entitled to indemnification hereunder, the indemnified party shall notify the
indemnifying part promptly, and in the case of a third party claim, in writing
within ten (10) days after the indemnified party's first receipt of written
notice of such third party claim, and in any event within such shorter period as
maybe legally required for the indemnifying party or parties to take appropriate
action to resist such claim. The failure to give a timely notice, as provided in
the preceding sentence, shall not operate as a waiver of any indemnified party's
right to indemnification, provided that the failure to give such notice did not
materially prejudice the legal rights of the indemnifying party. Such notice
shall specify all facts known to the indemnified part giving rise to such
indemnity rights and shall estimate (to the extent determinable) the amount of
liability
<PAGE>   9
arising therefrom.

         13.  EARLY TERMINATION.

plans. If Employee elects to take compensation payments in periodic
installments, then the Employer will continue to pay its share of the medical,
