Mr. John E. Telling
950 South Lagoon Lane
Mantoloking, NJ  08738

Dear John:

         This will confirm the Company's acceptance with regret of your
resignation as an officer, employee and Director of the Company effective
December 8, 1999. This letter together with your signature below will serve as a
record of the payments which will be made to you, shall serve as a record of
your equity position in the Company and shall set forth a mutual release and
certain continuing obligations. This letter shall supersede your May 24, 1999
Employment Agreement and any and all other agreements between you and the
Company which shall have no further force or effect.

         1. Payments. The Company will have payment obligations to you as set
forth in this Section 1 in respect of the period December 9, 1999 to May 23,
2004. You will be paid as follows:

                  (a) On January 31, 2000, the amount of $31,250 (which takes
into account the partial month of December 1999, payments previously made to
you, and the month of January 2000);

                  (b) On February 1, 2000 and on the first (1st) day of each
month thereafter until and including April 1, 2004, the amount of $20,833.33;

                  (c) On May 1, 2004, the amount of $15,456 (which takes into
account the partial month of May 2004); and

                  (d) On or before January 31, 2000 and on the [FIFTEENTH
(15TH)] day of each month thereafter commencing February 15, 2000 and until and
including December 15, 2000, the amount of $20,833.33.

Because you will not be an employee of the Company during the period in which
these payments are made, you shall be responsible for all income and other taxes
associated with such payments.

The Company may prepay all or any portion of such payments at any time, with
such payments to be credited in inverse order of maturity.

         2. Stock Ownership. You will be immediately vested in the 9099 shares
of the Company's common voting stock, $0.10 par value (the "Common Stock") which
were granted to you effective on May 24, 1999, representing 1% of the shares of
the Company's then issued and outstanding Common Stock, on a fully diluted
basis. Promptly after execution of this letter, you will receive a stock
certificate representing such shares. Such certificate will contain the
following restrictive legend:

                  The shares of capital stock represented by this certificate
                  have not been registered with the Securities and Exchange
                  Commission under the Securities Act of 1933, as amended (the
                  "Act"), in reliance upon an exemption from registration
                  provided by Section 4(2) the Act, nor with any state
                  securities regulatory authority in reliance upon particular
                  statutory transactional exemptions. The holder shall not
                  consummate a sale or other transfer of such shares without
                  prior registration under the Act under any applicable state
                  statute without first delivering to the Company an opinion of
                  counsel to the holder, which opinion is reasonably
                  satisfactory to the Company, to the effect that such proposed
                  sale or transfer is exempt from the registration provisions of
                  the Act and of all applicable state securities laws.

You will be paid on or before April 15, 2000 a bonus amount such that after your
payment of all federal, state and local income taxes, self-employment taxes, or
other taxes (including any interest or penalties, arising from the actions or
inactions of the Company, imposed with respect thereto) (the "Income Taxes")
imposed on such bonus you will retain an amount equal to the Income Taxes
imposed on you by the vesting of the Common Stock. The Company hereby confirms
that it has received an appraisal of the stock as of June 30, 1999 of $50 per
share. You will provide the Company's designee with any information necessary to
timely calculate such bonus.

         3. Stock Options. The Company hereby confirms that you were granted a
non-qualified option (the "Option") to acquire from the Company unauthorized but
unissued shares of its Common Stock in an aggregate number equal to three
percent (3%) of the shares of Common Stock issued and outstanding on May 24,
1999, inclusive of all shares of Common Stock then reserved for future issuance
upon the complete exercise of then outstanding option, warrant or rights grants
(including the option granted to you as referenced in this Section) provided
that if at the time of such intended issuance the Company constitutes a
subsidiary of another corporation or its corporate existence has been terminated
as a result of its merger into or consolidation with another corporation, then
Executive shall receive certificates representing an identical ownership in the
ultimate parent of the Company or the survivor of any such merger or
consolidation or, if no such parent shall then exist, then the survivor of the
merger or consolidation. The Option


<PAGE>   3

Mr. John E. Telling
December 31, 1999
Page 3


remains in full force and effect under the terms of this letter agreement and
the number of shares of Common Stock to which it relates is agreed to be 27,296.
The exercise price of each share the subject of the Option grant shall be
Twenty-Eight Dollars and 86 cents ($28.86), and the dates upon which the Option
may be exercised as to incremental portions shall be as follows:

    THE FOLLOWING PERCENTAGE                SHALL BE EXERCISABLE COMMENCING
      OF THE OPTION SHARES
<S>                                         <C>
               25%                                    July 1, 1999
               25%                                    July 1, 2000
               25%                                    July 1, 2001

</TABLE>

and each exercise right shall continue in force for a period of five (5) years
following its commencement. Further, on the date of any sale of all or
substantially all of the Company's assets or any merger, consolidation or other
combination transaction as the result of which the Company is not the surviving
entity (other than any merger effected for the principal purpose of
reincorporation in another jurisdiction or for another purpose not resulting in
at least a thirty percent (30%) change in the ultimate beneficial ownership of
the Company), you (or in the case of your legal incapacity, your legal
representative(s)) shall also be entitled to exercise the Option as to all
Option shares then otherwise ineligible for exercise (except those for which the
exercise period has expired), and within the six (6) month period following your
death, your representative or beneficiaries shall be entitled to exercise the
Option as to one half of all shares which would otherwise be ineligible for
acquisition as of the date of your death (except those for which the exercise
period has expired). The Option is not transferable other than by will or the
laws of descent and distribution. Except as set forth above the Option may only
be exercised by you during your lifetime. The Option may not be transferred,
assigned, pledged, hypothecated, or otherwise disposed of during your lifetime,
whether by operation of law or otherwise, and is not subject to execution,
attachment or similar process. Any attempt to transfer, assignment, pledge,
hypothecation, or other disposition of this Option contrary to the provisions
hereof, and the levy of an attachment or similar process upon the Option, shall
be null and void. The Company shall have the right to terminate the Option in
the event of such a transfer, assignment, pledge, hypothecation, or other
disposition, or levy of attachment or similar process, by notice to that affect
to the executive, provided, however, the termination of the Option shall
prejudice any rights or remedies which the Company may have under this agreement
or otherwise.

         4. Mutual Release. In consideration of the promises and covenants set
forth in this agreement:

             4.1 The Company's Release. The Company hereby releases and forever
discharges you and each of your legal representatives, heirs, beneficiaries and
assigns from and against any and all claims, losses, liabilities, obligations,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever (whether known or unknown, foreseen or
unforeseen, liquidated or contingent, currently existing or arising in the
future), arising from any

Page 4


act, omission, event, conduct or transaction having occurred on or before the
date of this agreement.

             4.2 Your Release. You hereby release and forever discharge the
Company and its trustees, officers, employees, agents, counsel, subsidiaries,
affiliates, successors and assigns from and against any and all claims, losses,
liabilities, obligations, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever (whether known or
unknown, foreseen or unforeseen, liquidated or contingent, currently existing or
arising in the future, and including under any applicable federal, state, or
local labor, contract, tort or anti-discrimination laws, or any claims for
violations of public policy, or for emotional distress), arising from any act,
omission, event, conduct or transaction having occurred on or before the date of
this agreement. Without limiting the generality of the foregoing, the Company
shall have no further obligation to you for any insurance or other employee
benefit.

         5. OWBPA Compliance. With respect to the waiver of your rights under
the Age Discrimination in Employment Act and the Older Worker's Benefit
Protection Act, you expressly acknowledge that you have up to 21 days from the
receipt of this agreement to review and consider this agreement. By signing this
letter agreement, you acknowledge that you have used as much of this 21 day
period as you needed. You understand that you may revoke this agreement within 7
days after you have signed it, and that the letter agreement will not become
effective or enforceable until the 7 day revocation period has expired.
Revocation must be made by delivering a written notice of revocation to Company
counsel no later than the close of business on the seventh day after you sign
this agreement.

         6. Confidentiality. During the Term, you will not disclose or use any
Confidential Information other than as specifically requested by the Company in
writing; and you agree to take all reasonable precautions to prevent inadvertent
disclosure or use of Confidential Information. For purposes of this agreement,
"Confidential Information" is defined as: the existence and terms of this
agreement, the Company's business strategy, sales, sales volume, sales methods,
sales proposals; customers and prospective customers, identity of customers and
prospective customers, identity of key purchasing personnel in the employ of
customers and prospective customers; amount or kind of customer purchases from
the Company, its sources of supply; the Company computer programs, systems
documentation, special hardware, product hardware, related software development,
the Company manuals, formulae, processes, methods, machines, compositions,
ideas, improvements, inventions; or other confidential or proprietary
information belonging to the Company or relating to the Company's affairs.
Confidential Information does not, however, include the general skills and
experience gained during your employment with the Company, or information
publicly available through no fault of yours, or information generally known
within the industries in which the Company competes. You agree that the
Confidential Information is the property of the Company; the use,
misappropriation, or disclosure of the Confidential Information would constitute
a breach of trust and could cause irreparable injury to the Company; and it is
essential to the protection of the Company's good will and to the maintenance of
the Company's competitive position that the Confidential Information be kept

secret and that you not disclose the Confidential Information to others or use
the Confidential Information to your own advantage or to the advantage of
others. You will promptly deliver to the Company all software programs,
questionnaires, files, manuals, letters, notes, notebooks, reports, customer
lists, and all other material containing Confidential Information which are in
your possession or under your control.

         7. Noncompetition.

                  (a) Basic Obligation. You will not Compete with the Company
                  (as hereinafter defined) for a period of time equal to the

                  make payment under Section 1 of this agreement (the "Term").

                  (b) Definition of "Compete with the Company." For the purposes
                  of this Section 7, the term "Compete with the Company" means
                  action by you in the continental United States, direct or

                  either as an officer, director, stockholder, owner, partner,
                  member, promoter, employee, consultant, advisor, agent,
                  manager, creditor or in any other capacity, resulting in your
                  having any pecuniary interest, legal or equitable ownership,

         8. Non-Solicitation. During the Term of this agreement plus a period of
two (2) years, you will not without prior consent of the Company, directly or
indirectly or on your own account, or as agent, employee, partner, stockholder
or otherwise, solicit, sell to or contract, with a view to selling any
long-distance services or any other product or service offered or sold by the
Company at any time during the Term of this agreement or any product or service
similar to, competitive with, or intended to compete with any such product or
service, to any person, firm or corporation from whom you or any person under

or cause to be solicited any employee of the Company, directly or indirectly, on

addition to and not in derogation of the provisions in Section 7 above.

         9. Remedies. You acknowledge that the Confidential Information which is
the subject of this agreement is valuable and unique and constitutes information
proprietary to the Company; that your breach or attempted breach of any
provision of Sections 6 through 8 would cause irreparable harm to the Company
not compensable in monetary damages; that the Company's remedy at law for any
such breach would be inadequate; and that, in addition to any other remedy, the
Company shall be entitled to temporary and permanent injunctive relief to enjoin
an actual or threatened breach of such provisions without being required to
prove damages or furnish any bond or other security.

         10. Arbitration. In the event of any dispute between the parties under

settled by arbitration in Oklahoma County, Oklahoma, in accordance with the
rules and regulations of the American Arbitration Association then in effect.
The arbitrator(s) shall have the right and authority to determine how their
award or decision as to each issue and matter in dispute may be implemented or
enforced. Any decision or award shall be final and conclusive on the parties;
there shall be no appeal therefrom other than for claimed bias, fraud or
misconduct by the arbitrator(s); judgment upon any award or decision may be
entered in any court of competent jurisdiction in the State of Oklahoma or
elsewhere; and the parties hereto consent to the application by any party in
interest to any court of competent jurisdiction for confirmation or enforcement
of such award. The party against whom a decision is made shall pay the fees of
the American Arbitration Association. Notwithstanding the foregoing, the
Company, at its sole option shall be entitled to enforce its rights, as
contemplated by Section 9 hereof, to injunctive and other equitable relief in
the event of a breach of Section 6, 7 or 8, thereof, either by arbitration
pursuant to this Section 10, or directly in any court of competent jurisdiction.

         11. Advice of Counsel. You acknowledge that the Company has expressly
advised you to seek the advice of an attorney before signing this agreement and
that you have had adequate time to do so.
