Dear Mr. Grohman:

         The  purpose of this letter is to set forth the  agreement  between you
and Viatel, Inc., its subsidiaries and their respective  predecessors including,
without  limitation,  Destia  Communications,   Inc.  (collectively  hereinafter
referred to as "Viatel")  regarding your  resignation as an officer and employee
of Viatel.  This Agreement  supersedes any prior  agreements  among the parties,
including the  Employment  Agreement  dated as of March 15, 2000 between you and
Viatel (the "Employment Agreement").

         As we have  discussed, in addition to your  resignation  (as described
above) Viatel desires to obtain your (i) release of all claims  against  Viatel,
(ii) a standstill  agreement as provided herein, and (iii) agreement to maintain
the  confidentiality of business  information of Viatel of which you have become
aware during the course of your employment  with Viatel.  You have agreed to the
foregoing  as  consideration  for  Viatel's  commitment  to  provide  to you the
benefits  set forth in  paragraph 2 below.  Based on these  considerations,  the
parties have mutually agreed as follows:

         1.  RESIGNATION. Effective as of April 7, 2001 (the "Effective  Date"),
your resignation as an officer and employee of Viatel is accepted.

         2.  PAYMENTS AND  BENEFITS.  Viatel will provide you with the following
payments and benefits:

         (a) SEVERANCE  PAYMENTS.  On the Effective Date,  Viatel will pay you a
cash lump sum payment of $102,271.56 which will be wired to an account specified
by you in writing.

         (b) SALARY/ACCRUED  AND UNUSED VACATION.  On the Effective Date, Viatel
shall pay you a lump sum cash  payment  equal to the amount,  if any, of accrued
but unpaid  base  salary and  vacation  due to you  pursuant  to the  Employment
Agreement and in accordance with Viatel's normal payroll policies. These amounts
shall be wired to an account specified by you in writing.

         (c) BENEFIT PLAN  PARTICIPATION.  Viatel shall continue to maintain any
health,  disability,  accidental death and disability,  business travel and life

<PAGE>

insurance  coverage and other health and benefit plans and programs to which you
were entitled  immediately prior to the date hereof, and Viatel will continue to
pay the employer  portion of the  applicable  premium  through  October 7, 2001,
provided, however, that any such benefits or payments shall cease if you receive
similar  benefits  from a subsequent  employer.  On or after such date,  you may
elect  COBRA  coverage  for up to an 18-month  period or such  longer  period as
provided in COBRA, at your own expense. Except as otherwise provided herein, you
will not be  entitled to any  compensation  or  benefits  (or any  reimbursement
therefore) or to  participate in any employee  benefit  programs of Viatel on or
after the date hereof.

         (d) 401(K)  RETIREMENT PLANS. You will be entitled to elect at any time
on or after the Effective  Date, a distribution  of any vested accrued  benefits
under  any  401(k),  pension  or other  type of  retirement  plan  sponsored  or
maintained by Viatel in accordance with the terms of such plans.

         (e)  OPTIONS/RESTRICTED  STOCK.  Any options that are not vested on the
Effective Date shall be automatically forfeited and any options vested as of the
Effective Date shall remain  exercisable in accordance  with their terms. On the
Effective Date,  Viatel will vest the 67,750 shares of restricted  stock granted
to you by Viatel and will deliver stock certificates representing such shares to
you without any restricted legend or other impairment of their negotiability.

         (f) EXPENSE  REIMBURSEMENT.  Viatel will  reimburse  you for all unpaid
business  expenses  incurred  or  paid by you  prior  to the  Effective  Date in
connection with the  performance of your duties under the Employment  Agreement,
upon  presentation  of  appropriate  documentation  in accordance  with Viatel's
customary procedures and policies applicable to its executives.

         (g) NO OTHER  COMPENSATION  OR BENEFITS.  Except as otherwise  provided
herein,  you  will not be  entitled  to any  compensation  or  benefits  (or any
reimbursement  therefor) or to  participate in any employee  benefit  program of
Viatel on or after the Effective Date.

         3.  YOUR RELEASE.

         (a)  Except as  otherwise  provided  herein,  in  consideration  of the

Dear Mr. Levy:

          The  purpose  of  this  letter  is to set  forth  the  agreement  (the
"Agreement")  between you and Viatel, Inc. and its subsidiaries and predecessors
(hereinafter  referred to collectively as "Viatel")  regarding your  resignation
from Viatel as an employee and director.

          1.   RESIGNATION/TRANSITION   SERVICES.   (a)  Viatel   accepts   your
resignation  as an officer and  director of Viatel  effective  February 23, 2000
(the  "Effective  Date").  From the date hereof through and including  March 31,
2000 (the "Termination  Date"), you shall continue to provide services to Viatel
as a non-executive  employee, for a maximum of twenty (20) hours per week, which
will be performed in a maximum of three (3) business days per week. In the event
that you perform  services in excess of twenty (20) hours in any week, your time
commitment  for any  subsequent  week will be  reduced by the amount of any such
excess hours. From the date hereof through the Termination Date (the "Transition
Period"),  you will  report  solely to William  Murphy and will  assist him with
regard to transitional issues. Viatel acknowledges and agrees that the principal
location for the  performance  of such  transitional  services will be either at
your principal residence in Woodcliff Lake, New Jersey or at Viatel's offices in
Now York,  except that, upon reasonable  notice,  Viatel may reasonably  request
that you perform such act-Vices in the United Kingdom or in any other country in
which Viatel  conducts its  business.  In the event you are requested to perform
services  outside  the United  States,  Viatel  will  assist you with  regard to
planning  your  travel  arrangements  and will pay for  your  business  expenses
associated  with any such  business  trip (which  shall  include  business-class
airfare).  Notwithstanding anything herein to the contrary,  Viatel acknowledges
that  you  will be  taking  a  one-week  vacation  paid by  Viatel  for the week
commencing  March 25,  2000 and that you will not be  required  to  perform  any
service during that week, however, you agree to be reasonably available by phone
to respond to any issues that may arise.

          (b) Through the  Termination  Date,  Viatel will reimburse you for all
unpaid business  expenses  incurred or paid by you prior to the Termination Date
in connection  with the  performance  of your duties prior to the date hereof or
contemplated   hereby,   upon  presentation  of  appropriate   documentation  in
accordance  with Viatel's  customary  procedures and policies  applicable to its
executives, Without limiting the generality of the foregoing Viatel acknowledges
that it is  responsible  fur, and shall  promptly pay, all  reasonable  business
expenses billed to your corporate American Express card.

          (c) You will have no authority to bind, make any commitments on behalf
of or, except as specifically contemplated hereunder, otherwise act an behalf of
Viatel in any manner  whatsoever  on or after the date hereof.  You agree not to
take any action, or intentionally fail to take any action, which would cause any
third party to assume that you have any such authority.

<PAGE>

          2. PAYMENT AND  BENEFITS.  Viatel will provide you with the  following
payments and benefits:

          (a) SALARY. On the Effective Date, Viatel will pay you a cash lump sum
payment equal to the amount, if any, of accrued but unpaid base salary.

          (b) TRANSITION  PAYMENTS.  During the Transition  Period,  Viatel will
continue to pay you your base salary,  based on the rate of your current  annual
base salary of $345,000,  payable in accordance with Viatel's payroll  practices
applicable to you in effect prior to the date hereof.

          (c) BONUS. In the event that Viatel pays bonuses to its current senior
executives with employment  agreements with respect to services performed in the
2000  calendar  year,  upon the earlier of (i) the date that bonuses are paid to
such Viatel  executives  with respect to the 2000  calendar year or (ii) January
31, 2001, Viatel will pay you a cash lump sum representing the pro rated portion
of your Bonus Award (as defined in your  employment  agreement with Viatel dated
August 27, 1999 (the  "Employment  Agreement"))  as if you were employed for the
entire  2000  Performance  Year (as  defined in the  Employment  Agreement)  and
multiplying  such Bonus Award by a fraction,  of which: (i) the numerator is the
number of days beginning of January 1, 2000 and ending on the  Termination  Date
and (ii) the denominator is 365. The parties hereto  acknowledge  that the Bonus
Award is intended to be calculated and made in accordance with Section 3.2(c) of
the Employment Agreement.

          (d) SEVERANCE.  Subject to Section 12 hereof, on the Termination Date,
Viatel will pay you a cash lump sum payment of $57,500,  representing  severance
equal to two (2) months' base salary. In addition to the foregoing, in the event
that JazzTel plc, any of its subsidiaries or any entity  controlled,  indirectly
or directly by, or under common  control with,  Martin  Varsavsky,  completes an
acquisition  of  Viatel  commenced  at any  time  from the  date  hereof  to and
including  August  23,  2000,  Viatel  will pay you a cash lump sum  payment  of
$500,000 (the "COC Severance Amount).

          (e) 401(K)/RETIREMENT  PLANS. You will be entitled to elect at anytime
on or after the Termination  Date, a distribution of any vested accrued benefits
under  any  401(k),  pension  or other  type of  retirement  plan  sponsored  or

of the foregoing,  on the Termination Date, Viatel will cause the trustee of the
Destia 401(k) Plan to distribute  your entire account balance under such plan by
wire  transfer  in  a  direct  rollover  to  an  individual  retirement  account
established at Donaldson, Lufkin & Jenrette ("DLJ") by you.

          (f) BENEFIT PLAN  PARTICIPATION.  Viatel will continue to maintain any
health,  disability,  AD&D, business travel and life insurance coverage to which
you were entitled immediately prior to the date hereof, and Viatel will continue
to pay the employer  portion of the applicable  premiums,  until the Termination
Date.  On and  after  the  Termination  Date,  you,  your  spouse  and  eligible
dependents may elect COBRA  continuation  health  coverage for up to an 18-month
period  or such  longer  period  as  provided  in COBRA at your  expense  at the
standard  COBRA rate  applicable  to other former  employees.  No later than the
Termination  Date  we will  provide  more  information  to you  regarding  COBRA
benefits and the election forms.  Except with respect to your, your spouse's and
your eligible  dependents' rights under COBRA,  failure of Viatel to provide any
such  information  and  forms,  however,  shall not in any  event  result in any
adverse impact on Viatel or any rights it may have under this Agreement.

of wireless voice or data services, any internet service provider, or any DSL or
local loop  provider,  that is  competitive  with Viatel's  business  within the
United  States or any European  country in which Viatel  currently  conducts any
business  (including the solicitation of any customer of Viatel on behalf of any
competitor or any other business,  directly,  indirectly on behalf of himself or
any other person or entity) (collectively, "Competitive Activities"). Viatel and
you agree that the scope of your  non-competition  covenant will be as set forth
in this Section 8, notwithstanding any non-competition covenant contained in any
other agreement between you and the Company.  Notwithstanding anything herein to
the contrary: (i) you shall be permitted to make minority investments in private
businesses  in which you are  neither  employed  nor  serving as a  director  or
equivalent  position;  and (ii) this Section 8 shall become null and void on and
after May 1, 2000 and be of no further force or effect.

          9.  NON-SOLICITATION.  For a period of  eighteen  (18) months from the
Termination Date, you shall not solicit,  induce,  counsel,  advise or encourage
either  directly  or  indirectly,  any  employee of Viatel who is employed in an
executive,  managerial,  professional or non-clerical administrative capacity to
leave the employment of Viatel.

          10. NON-DISPARAGEMENT. You and Viatel will not at any time, and Viatel
shall use its best  efforts to ensure  that the Viatel  Persons  will not at any
time,  make any  statement,  whether  written or oral,  or take any other action
which is intended, or could reasonably be expected to, disparage, defame or harm
the reputation (or otherwise cause adverse  publicity) of the other party. In no
event shall any public  statements be made about Viatel or you without the prior
written consent of the other party. You and Viatel also each agree that you will
not assist in any  litigation or  instigation  against the other party except as
required by law.

          11. NON-DISCLOSURE. You and Viatel agree that the terms and conditions
of this Agreement are  confidential  and that each will not, without the express
prior  written  consent of the other party,  in any manner  publish,  publicize,
disclose,  or otherwise make known or permit or cause to be known such terms and
conditions to anyone (other than such party's  prospective  or current  lenders,
financial  advisors  and legal  advisors,  who  shall  agree to be bound by this
paragraph  prior to  disclosure  of the  terms  and  conditions  hereof  to such
persons),  except as required by law, or in any proceeding to enforce then terms
of this  Agreement.  The parties  hereto shall  mutually agree in writing on the
terms of any statement or communication about the circumstances surrounding your
termination  including,  without  limitation,  the terms of any press release or
memo to any officer or employee of Viatel.

          12. REMEDIES.  If you or Viatel should breach each of your or Viatel's
obligations  under the foregoing  paragraphs,  in addition to and not in lieu of
any  other  rights  which  either  party  may  have  at  law  or in  equity  and
contemplated by Section 13 hereof, the non-breaching  party shall have the right
to obtain injunctive  relief, it being acknowledged by the parties that any such
breach would cause  irreparable harm and continuing  injury to the non-breaching
party and that money damages  alone would not provide an adequate  remedy to the
non-breaching  party.  In  the  event  you  breach  in a  material  manner  your
obligations under Sections 6 through 11 hereof, Viatel shall also have the right
to declare (by written  notice to you) and  enforce the  forfeiture  of the cash
amounts  payable  under  Sections  2(c) and 2(d)  hereof.  In the  event  Viatel
breaches  in a material  manner its  obligations  hereunder,  you shall have the
right (by written  notice to Viatel) to cease  performing  any services  through

                                       7
<PAGE>

April  1,  2000  and  you  shall  not be  required  to  comply  with  any of the
restrictive  covenants  under Sections 6 through 11 hereof,  provided,  however,
that if you cease to perform  duties  pursuant to this  Section 12, your date of
cessation shall become your Termination Date and you will not be entitled to the
severance under Section 2(d) of this Agreement.

          13. NO WAIVER.  This Agreement  constitutes  the entire  agreement and
understanding  between  you and Viatel and  supersedes  any prior  agreement  or
understanding,  oral or written, between the parties, including, but not limited
to the Employment Agreement (except as specifically referred to herein). None of
the  provisions of this  Agreement  can be waived or modified  except in writing
signed by both parties.  This  Agreement  shall be binding upon and inure to the
benefit of you and your heirs,  legal  administrators  and assigns and  Viatel's
successors   and   assigns   (whether   by  merger,   consolidation,   purchase,
reorganization,  sale of  stock,  sale of  assets,  liquidation  or  otherwise).
Furthermore,  there are no agreements,  covenants or  understandings  other than
those contained  herein except as govern the  compensation and benefit plans and
arrangements set forth herein.

          14. SEVERABILITY.  If any term or provision of this Agreement shall be
held  invalid or  unenforceable,  the  remaining  terms and  provisions  of this
Agreement shall not be affected thereby and (i) such provision shall be reformed
to the minimum extent  necessary to be valid while  preserving the intent of the
parties as expressed  herein,  or (ii) if such provision  cannot be so reformed,
such provision shall be severed from this Agreement and an equitable  adjustment
shall be made to this  Agreement  (including,  without  limitation,  addition of
necessary  further  provisions  to this  Agreement)  so as to give effect to the
intent as so expressed  and the  benefits so provided.  Neither such holding nor
such   reformation  nor  severance  shall  affect  or  impair  the  legality  or
enforceability of any other provision of this Agreement.

          15.  REVOCATION.  You  acknowledge  and  agree  that by  signing  this
Agreement,  you understand that you  voluntarily  waive the right to revoke this
Agreement  during  the seven  (7) day  period  following  the  execution  of the
Agreement.

          16.  MISCELLANEOUS.  In the event that Viatel fails to pay any amounts
provided  hereunder or either  party  otherwise  breaches any  provision of this
Agreement, either in whole or in part, the non-breaching party shall be entitled
to recover  from the other  party,  in addition  to the  recovery of its damages
and/or other relief, any costs,  including reasonable  attorneys' fees, incurred
or reasonably  expected to be incurred in instituting,  prosecuting or defending
any action arising by reason of such failure or the breach of this Agreement.

          17. TAX WITHHOLDING.  Solely to the extent that any payment  hereunder
is subject to  withholding  for federal,  state or local income taxes or federal
employment  taxes,  Viatel agrees to withhold the minimum  amount of withholding
taxes  required by law.  With  respect to the shares of  Restricted  Stock which
become  vested  hereunder,  Viatel  shall  reduce the amount of shares of Common
Stock  otherwise  deliverable  to you to cover the minimum amount of withholding
taxes  required  by law.  Viatel  represents  and  warrants  that,  prior to the
Effective  Date, it shall have obtained  approval by Viatel's Board of Directors
or a compensation  committee of such board which consists solely of at least two
(2) non-employee  directors,  of the reduction of such shares of Common Stock so
that it will be  treated as an exempt  "disposition  to the  issuer"  under Rule
16b-3 promulgated under Section 16(b) of the Exchange Act.

          18.  TAX  INDEMNITY.  Viatel  shall  select  and  retain a law firm or
accounting firm with a national  reputation  (which may be Viatel's  current law
firm or auditors) to determine whether you have a reasonable  reporting position
that the  acceleration of stock options under your employment  agreement,  dated
May 3, 1999 with Destia Communications, Inc., (the "Payments") is not subject to
the excise tax imposed under Sections 280G and 4999 of the Internal Revenue Code
of 1986, as amended (the "Code"). The advice of such law firm or accounting firm
shall be provided  to you in writing  within  thirty (30) days of the  Effective
Date.  Upon  receipt  of such  written  advice,  you agree to take a  consistent
position with such advice.  Notwithstanding  anything herein to the contrary, in
the event  that all or any  portion of the  Payments  will be or are found to be
subject to the tax imposed under Sections 280G and 4999 of the Code (the "Excise
Tax"), Viatel shall indemnify you up to $3 million for, and, if required,  shall
pay, the Excise Tax plus all interest and penalties  resulting  from the payment
of or failure to pay the Excise Tax.

          19. INDEMNIFICATION;  D&O INSURANCE. Viatel hereby agrees to indemnify
you  against  any  and all  expenses  (including  attorney's  fees  and  costs),
liabilities,  costs, damages,  judgments,  fines and amounts paid in settlement,
actually and reasonably  incurred by you, to the fullest extent now or hereafter
permitted  by law,  in  connection  with any  threatened,  pending or  completed
action,  suit  or  proceeding,   whether  civil,  criminal,   administrative  or
investigative, brought or threatened to be brought against you by reason of your
performance as a director,  officer,  employee or agent of Viatel. The rights of
indemnification  provided  for herein  shall be not be deemed  exclusive  of any
other rights to which you may be entitled under Viatel's  By-laws or Certificate
of  Incorporation,  and shall inure to the benefit of your heirs,  executors and
administrators.  Any expenses (including  reasonable  attorney's fees and costs)
incurred  by you in  connection  with an  event  for  which  indemnification  is
provided  hereunder  shall be paid  promptly  by Viatel in  advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
you to repay such amount if it shall  ultimately be determined  that you are not
entitled to be indemnified by Viatel as authorized by law.  Viatel will continue
to maintain  Directors' and Officers'  Liability Insurance (the "D&O Insurance")
for you until the sixth  anniversary  of the Effective Date in an amount no less
than the same amount currently provided to Viatel's directors and officers.
