JOHANNES SEEFRIED ("Seefried").

       In consideration of the mutual covenants contained herein, the parties
hereto agree as follows:

     1.        Term.  The Company hereby employs Seefried as the Chief
               -----
Financial Officer of the Company, and Seefried agrees to serve the Company as
such, upon the terms and Conditions hereof for the period commencing on the date
hereof and, unless Seefried's employment under the Agreement is otherwise
terminated in accordance with the provisions hereof, ending on December 31,
2000.

     2.         Duties, (a) Seefried shall serve as the Company's Chief
                ------
Financial Officer, with such duties and authority as are generally incident to
such position. Seefried will hold such senior offices and/or such
Directorships in the Company and/or any subsidiaries or affiliates of the
Company to which, from time to time, he  may be elected or appointed; provided
that the offices to which Seefried may be so elected or appointed shall not
be inconsistent with his duties and authority as aforesaid.

                         (b) Seefried agrees that he will devote substantially
all of his time and attention to the affairs of the Company and use his best
efforts to promote the business and interests of the Company and that he will
not engage, directly or indirectly, in any other business or occupation during
the term of employment hereunder.  It is understood, however, that the foregoing
will not prohibit Seefried from engaging in personal investment activities for
himself and his family that do not detrimentally interfere with the performance
of his duties hereunder.

     3.       Compensation. The Company will pay Seefried an annual salary
              ------------
("Base Salary") at an annual rate of $200,000 for the calendar year 2000,

practices for senior executives of the Company for all services to be rendered
hereunder, including, without limitation, all services to be rendered by him as
an officer and/or director of the Company and its subsidiaries and affiliates.
In addition all existing benefits including medical benefits and the existing
car allowance benefit shall remain in place until the end of the term of this
employment agreement.

                In addition to the Annual Bonus described below, as an incentive
to execute this employment agreement and in recognition of his successful
closing of the Tail Wind Fund private placement agreement, the Board of
Directors granted Seefried on May 24, 2000 twenty-five thousand (25,000) options
on its common stock (of which up to $100,000 in value are

<PAGE>
<PAGE>


eligible for a incentive stock option award), subject to shareowner approval of
an increase in the number of shares in the Company Stock Option Plan, at a
strike price of $10.25, vesting and exercisable on the grant date.

            Additional Financing Performance Bonus: Simultaneously with the
execution of this employment agreement, the Company by resolution of the
Compensation Committee of the Board of Directors hereby grant's Seefried a
performance bonus of up to One hundred thousand (100,000) non-qualified stock
options on its Common Stock at a strike price equal to the closing price on the
date of signing of this agreement, subject to shareowner approval of an increase
in the number of shares in the Company Stock Option Plan, based solely upon the
Company obtaining any additional public or private financing or investment by
May 31, 2001. Of such grant, Fifty-thousand (50,000) options shall be vested and
exercisable on the closing of any financing or investment of up to and including
Five Million dollars ($5,000,000).  An additional Twenty five thousand (25,000)
options shall be vested and exercisable on the closing of any financing or
investment of over Five Million dollars ($5,000,000) up to and including Seven
and one half million dollars ($7,500,000). An additional Twenty-five thousand
(25,000) options, for a total of one hundred thousand (100,000) options, shall
be
granted if the Company obtains any additional financing or investment over Seven
and one-half million dollars ($7,500,000).  These options shall be vested and
exercisable immediately upon closing of the additional financing or investment.
Seefried agrees that he will use his best efforts to obtain such additional
financing during his employment and the Company agrees that these options shall
be issued to Seefried irrespective of whether he personally negotiated the
financing arrangements or whether the additional financing occurred after his
termination of employment for any reason, notwithstanding any other provision in
this agreement to the contrary.

                 Employment Agreement Supercedes:  To the extent that any
provisions of this employment agreement conflict with or are inconsistent with
any provision in the 1998 stock incentive plan of Ursus Telecom Corporation or
any subsequently revised Company stock incentive plan, the provisions of this
employment agreement shall control; and any inconsistent or conflicting
provision of the Company's employee stock incentive plan shall be null and
void.

simultaneously with the execution of this employment agreement the Company by
resolution of the Compensation Committee of the Board of Directors hereby grants
Seefried a performance bonus of Seventy-five thousand (75,000) non-qualified
stock options on its Common Stock at a strike price equal to the closing price

associated with or work for an entity with which Seefried is then associated or
working with, in compliance with the non-compete provisions of Section 13
(a) (e.g., for an employer not within the State of Florida).

      (c) If any of the covenants contained in this Section 13 or any part
thereof is held by a court of competent jurisdiction to be unenforceable because
of the duration of such provision, the activity limited by or the
subject of such provision and/or the area covered thereby, then the court making
such determination shall construe such restriction so as to thereafter be
limited or reduced to be enforceable to the greatest extent permissible by
applicable law.

are not performed strictly in accordance with their terms or are otherwise
breached. Seefried hereby expressly agrees that the Company shall be entitled as

other remedies permitted by law, to prevent a breach or violation by Seefried
and to secure enforcement of the provisions of Sections 13, 14, 15 or 16 hereof.

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

shall be deemed valid unless by full performance of the parties hereto or by a
writing signed by the parties hereto. No waiver by the Company or Seefried of

at the same time or any prior or subsequent time. This Agreement supersedes and
controls over all previous agreements between the Company and Seefried regarding
his employment by the Company.

        21.    Severability. In case any provision in this Agreement shall be
               ------------
