Item 5. Other Events.

     On August 27, 1999, Viatel,  Inc., a Delaware  corporation (the "Company"),
Viatel Acquisition Corp., a Delaware  corporation and a wholly-owned  subsidiary
of the Company  ("Merger  Sub"),  and Destia  Communications,  Inc.,  a Delaware
corporation  ("Destia"),  entered  into an  Agreement  and Plan of  Merger  (the
"Merger  Agreement"),  which provides,  among other things,  for the merger (the
"Merger") of Merger Sub with and into Destia.  Upon  consummation of the Merger,
Destia will become a wholly-owned subsidiary of the Company.

     Under the terms of the Merger Agreement,  Destia  stockholders will receive
0.445 share of the Company's  common  stock in exchange for each share of Destia
common stock held by the such stockholders at the effective time of the Merger.

     The transaction is contingent  upon,  among other things,  approval by both
the Company's and Destia's stockholders, certain regulatory approvals (including
approval  under the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976 and
certain telecommunications regulatory approvals) and other customary conditions.
Holders of over a majority of Destia's  voting  common stock have agreed to vote
in favor of the Merger.

     The Merger is  intended to  constitute  a tax-free  reorganization,  and is
expected to be completed by year end.

               (i) GENERAL.  The Merger shall become  effective at the time (the
          "EFFECTIVE  TIME")  the  Company  and the Parent  Subsidiary  file the
          Certificate  of  Merger  with the  Secretary  of State of the State of

          entirety  as did  the  By-laws  of the  Parent  Subsidiary  in  effect
          immediately  prior to the  Effective  Time and shall be the By-laws of
          the  Surviving  Corporation  (except  that the  name of the  Surviving

               (iv)  DIRECTORS AND  OFFICERS.  The directors and officers of the
          Parent Subsidiary immediately prior to the Effective Time shall be the
          directors and officers of the Surviving  Corporation  at and as of the

          shall be converted  into the right to receive 0.445 Parent Shares (the

          no longer be outstanding,  shall be canceled and shall cease to exist,
          and each holder of a certificate  representing any such Company Shares
          shall thereafter cease to have any rights with respect to such Company
          Shares, except the right to receive the Per Share Merger Consideration
          for  each  such   Company   Share  and  any   unpaid   dividends   and

          to be  outstanding  or to have any  rights  other than those set forth
          above in  thisss.2(d)(v)  after the  Effective  Time.  Notwithstanding
          anything  to the  contrary in  thisss.2(d)(v),  no  fractional  Parent
          Shares shall be issued to then former  holders of Company  Shares.  In
          lieu  thereof,  each then former  holder of a Company  Share who would
          otherwise  have been  entitled to receive a fraction of a Parent Share
          (after  taking into  account all  certificates  delivered by such then
          former  holder at any one time) shall  receive an amount in cash equal
          to such  fraction of a Parent Share  multiplied  by the Closing  Sales
          Price per Parent Share on the date of the Effective Time.

               (vi) CONVERSION OF STOCK RIGHTS.  The Company shall take all such
          action as may be necessary to cause, at the Effective Time, each Stock
          Right (but excluding rights of holders of Nonvoting Shares to exchange
          such  shares for Voting  Shares)  granted by the  Company to  purchase
          Company Shares which is outstanding and unexercised  immediately prior
          thereto  (whether  or not  vested  or  exercisable),  to be  converted
          automatically into an equivalent Stock Right to purchase Parent Shares
          in an amount and at an exercise price determined as follows:

                    (x) The  number of Parent  Shares to be  subject  to the new
               Stock  Right  shall be  equal to the  product  of the  number  of
               Company Shares subject to the original Stock Right  multiplied by
               the Per Share Merger Consideration,  provided that any fractional
               Parent Shares resulting from such multiplication shall be rounded
               as provided in the  instrument  governing such Stock Right or, if
               there is no such instrument, up to the next whole share; and

                    (y) The exercise  price per Parent Share under the new Stock
               Right shall be equal to the  quotient of the  exercise  price per
               Company  Share under the original  Stock Right divided by the Per
               Share Merger  Consideration,  provided  that the  exercise  price
               resulting  from such division shall be rounded as provided in the
               instrument  governing  such  Stock  Right or, if there is no such
               instrument, up to the next whole cent.

          The  adjustments  provided  herein with respect to any original  Stock
          Rights which are "incentive  stock options" (as defined in Section 422
          of the Code)  shall be and are  intended  to be  effected  in a manner
          which is consistent  with Section  424(a) of the Code. The option plan
          of the Company under which the original Stock Rights were issued shall
          be assumed  by Parent,  and the  duration  and other  terms of the new
          Stock Rights shall be the same as the original  Stock  Rights,  except
          that all references to the Company shall be deemed to be references to
          Parent.  At the  Effective  Time,  Parent shall deliver to then former
          holders of original Stock Rights appropriate  agreements  representing
          the right to acquire  Parent  Shares on the terms and  conditions  set
          forth in this ss. 2(d)(vi).

          registration  statement or  registration  statements (and maintain the
          current status of the prospectus or  prospectuses  contained  therein)
          for so long as such options remain outstanding.  With respect to those
          individuals  who  subsequent  to the  Merger  will be  subject  to the
          reporting  requirements under Section 16(a) of the Securities Exchange
          Act, Parent shall administer the option plans assumed pursuant to this
          ss.  2(d)(vi) in a manner that  complies  with Rule 16b-3  promulgated
          under the  Securities  Exchange  Act to the extent the Company  option
          plan  complied  with  such  rule  prior  to the  Merger.  Prior to the
          Effective  Time,  Parent  shall take all actions as may be required to
          cause the acquisition of equity  securities of Parent, as contemplated
          by this ss.  2(d)(vi),  by any Person who is or will become a director
          or officer of Parent to be eligible for exemption  under Rule 16b-3(d)
          promulgated under the Securities Exchange Act.

               (vii)  CONVERSION OF CAPITAL STOCK OF THE PARENT  SUBSIDIARY.  At
          and as of the Effective  Time,  each share of common  stock,  $.01 par
          value per share, of the Parent  Subsidiary shall be converted into one
          share of common  stock,  $.01 par value per  share,  of the  Surviving
          Corporation.

     (e)  PROCEDURE FOR EXCHANGE.

          (i)  Immediately  after the Effective Time, (A) Parent will furnish to
     The Bank of New York,  its  transfer  agent,  or such  other  bank or trust
     company reasonably acceptable to the Company, to act as exchange agent (the
     "EXCHANGE  AGENT") a corpus  (the  "EXCHANGE  FUND")  consisting  of Parent
     Shares  and cash  sufficient  to  permit  the  Exchange  Agent to make full
     payment of the Merger Consideration to the holders of all of the issued and
     outstanding  Company Shares (other than any Company Shares owned by Parent,
     Parent  Subsidiary or the Company),  and (B) Parent will cause the Exchange
     Agent to mail a letter of transmittal (with  instructions for its use) in a
     form to be mutually  agreed upon by the Company and Parent prior to Closing
     to each holder of issued and  outstanding  Company  Shares  (other than any
     Company Shares owned by Parent,  the Parent  Subsidiary or the Company) for
     the holder to use in surrendering the certificates which, immediately prior
     to the  Effective  Time,  represented  his or its  Company  Shares  against
     payment  of the  Merger  Consideration  to which  such  holder is  entitled
     pursuant  toss.2(d)(v).  Upon  surrender  to the  Exchange  Agent  of  such
     certificates,  together with such letter of transmittal,  duly executed and
     completed  in  accordance  with  the  instructions  thereto,  Parent  shall
     promptly cause to be issued a certificate representing that number of whole
     Parent  Shares and a check  representing  the amount of cash in lieu of any
     fractional shares and unpaid



                                     - 10 -
<PAGE>

     dividends  and  distributions,  if any, to which such Persons are entitled,
     after giving effect to any required tax  withholdings.  No interest will be
     paid  or  accrued  on the  cash in lieu of  fractional  shares  and  unpaid
     dividends  and  distributions,  if any,  payable  to  recipients  of Parent
     Shares.  If  payment is to be made to a Person  other  than the  registered
     holder of the  certificate  surrendered,  it shall be a  condition  of such
     payment that the certificate so surrendered  shall be properly  endorsed or
     otherwise in proper form for transfer and that the Person  requesting  such
     payment  shall pay any  transfer or other  taxes  required by reason of the
     payment to a Person  other than the  registered  holder of the  certificate
     surrendered  or establish to the reasonable  satisfaction  of the Surviving
     Corporation  or the  Exchange  Agent  that such tax has been paid or is not
     applicable.  In the event any certificate representing Company Shares shall
     have been lost,  stolen or  destroyed,  upon the making of an  affidavit of
     that fact by the Person  claiming such  certificate  to be lost,  stolen or
     destroyed,  the Exchange Agent will issue in exchange for such lost, stolen
     or destroyed  certificate the Merger  Consideration  deliverable in respect
     thereof; provided, however, the Person to whom such Merger Consideration is
     paid shall,  as a condition  precedent  to the  payment  thereof,  give the
     Surviving  Corporation  a bond in such sum as it may  direct  or  otherwise
     indemnify the Surviving Corporation in a manner reasonably  satisfactory to
     it against  any claim that may be made  against the  Surviving  Corporation
     with  respect  to the  certificate  alleged  to have been  lost,  stolen or
     destroyed. No dividends or other distributions declared after the Effective
     Time with  respect to Parent  Shares and  payable to the  holders of record
     thereof shall be paid to the holder of any unsurrendered  certificate until
     the holder  thereof shall  surrender such  certificate  in accordance  with
     thisss.2(e).  After the  surrender  of a  certificate  in  accordance  with
     thisss.2(e),  the record  holder  thereof  shall be entitled to receive any
     such dividends or other distributions,  without any interest thereon, which
     theretofore   had  become   payable  with  respect  to  the  Parent  Shares
     represented by such certificate.  No holder of an unsurrendered certificate
     shall be entitled,  until the  surrender of such  certificate,  to vote the
     Parent  Shares  into  which  his or its  Company  Shares  shall  have  been
     converted into the right to receive.

          (ii) The Company will cause its transfer agent to furnish  promptly to
     the Parent Subsidiary a list, as of a recent date, of the record holders of
     Company Shares and their  addresses,  as well as mailing labels  containing
     the names and addresses of all record  holders of Company  Shares and lists
     of security  positions of Company  Shares held in stock  depositories.  The
     Company will furnish the Parent Subsidiary with such additional information
     (including,  but not limited to, updated lists of holders of Company Shares
     and their  addresses,  mailing labels and lists of security  positions) and
     such other  assistance  as Parent or the Parent  Subsidiary or their agents
     may reasonably request.

          (iii)  The  Parent  may cause the  Exchange  Agent to invest  the cash
     included  in the  Exchange  Fund in one or  more  investments  selected  by
     Parent; provided, however, that the terms and conditions of the investments
     shall be such as to permit the Exchange Agent to make prompt payment of the
     Merger Consideration as necessary.  The Parent may cause the Exchange Agent
     to pay



                                     - 11 -
<PAGE>

     over to the  Surviving  Corporation  any net  earnings  with respect to the
     investments,  and Parent will replace  promptly any portion of the Exchange
     Fund which the Exchange Agent loses through investments.

          (iv)  The  Parent  may  cause  the  Exchange  Agent to pay over to the
     Surviving  Corporation  any portion of the  Exchange  Fund  (including  any
     earnings  thereon)  remaining  180  days  after  the  Effective  Time,  and
     thereafter all former stockholders of the Company shall be entitled to look
     to the Surviving  Corporation  (subject to abandoned property,  escheat and
     other  similar laws) as general  creditors  thereof with respect to the Per
     Share Merger  Consideration  and any cash  payable upon  surrender of their
     certificates.

          (v) The Parent shall pay, or shall cause the Surviving  Corporation to
     pay, all charges and expenses of the Exchange Agent.

          (f) CLOSING OF TRANSFER RECORDS. After the Effective Time, no transfer
of Company Shares  outstanding  prior to the Effective Time shall be made on the
stock transfer books of the Surviving Corporation. If, after the Effective Time,
certificates representing such shares are presented for transfer to the Exchange
Agent, they shall be canceled and exchanged for certificates representing Parent
Shares,  cash in lieu of  fractional  shares,  if any, and unpaid  dividends and
distributions, if any, as provided in ss.2(e).

          (g) DISSENTERS'  RIGHTS.  The holders of Nonvoting  Shares as to which
dissenters'  rights  shall have been duly  demanded  under  applicable  law (the
"DISSENTING  SHARES"),  if any,  shall be entitled  to payment by the  Surviving
Corporation  only of the  fair  value  of such  Nonvoting  Shares  plus  accrued
interest to the extent  permitted by and in  accordance  with the  provisions of
applicable law; provided,  however,  that (i) if any holder of Dissenting Shares
shall, under the circumstances permitted by applicable law, subsequently deliver
a written  withdrawal  of such  holder's  demand or (ii) if any holder  fails to
establish  such  holder's  entitlement  to rights of payment as  provided  under
applicable  law,  such holder or holders (as the case may be) shall forfeit such
right to payment  for such  Nonvoting  Shares and such  Nonvoting  Shares  shall
thereupon  be  deemed  to have  been  converted  into  Parent  Shares  as of the
Effective Time.

     3.  REPRESENTATIONS  AND WARRANTIES OF THE COMPANY.  The Company represents
and warrants to Parent and the Parent Subsidiary:

          (a) ORGANIZATION,  QUALIFICATION AND CORPORATE POWER. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of Delaware. If applicable to such country,  each of the Company's  Subsidiaries
operating in such country has been duly incorporated or otherwise organized,  is
validly existing and, in jurisdictions where the concept is applicable,  in good
standing  under  the  laws  of  the   jurisdiction  of  its   incorporation   or
organization.  Each of the Company and its  Subsidiaries  is duly  authorized to
conduct  business and is in good  standing  under the laws of each  jurisdiction
where  such   qualification   is  required,   except  where  the  lack  of  such
qualification or failure to be in good standing would not reasonably be expected
to have a  material  adverse  effect on the  business,  financial  condition  or
results of operations of the Company and its Subsidiaries taken as a whole or on
the ability of the Company to consummate the  transactions  contemplated by this
Agreement (a "COMPANY



                                     - 12 -

MATERIAL  ADVERSE  EFFECT").  Each of the Company and its  Subsidiaries has full
corporate power and corporate  authority,  and all foreign,  federal,  state and
local  governmental  permits,  licenses and  consents,  required to carry on the
businesses  in which it is engaged and to own and use the  properties  owned and
used by it, except for such permits,  licenses and consents the failure of which
to have would not  reasonably  be  expected to have a Company  Material  Adverse
Effect.  The  Company  does  not own any  equity  interest  in any  corporation,
partnership,  limited  liability  company,  joint  venture or other legal entity
other than the Subsidiaries  listed in ss.3(a) of the Company  Disclosure Letter

of which are issued and  outstanding  as of August 26, 1999,  75,000,000  Voting
Shares,  of which  31,226,052  Voting Shares were issued and  outstanding  as of
August 26,  1999 and no Voting  Shares  were held in  treasury  as of August 26,

warrant  entitling  the holder  thereof to purchase  8.485  Voting  Shares at an
exercise  price of $0.01 per  Voting  Share (the  "WARRANTS").  As of August 26,
1999,  1,315,148 Voting Shares were subject to issuance pursuant to the Warrants

outstanding   or  authorized   stock   appreciation,   phantom   stock,   profit
participation  or  similar  rights  with  respect  to the  Company or any of its

there are no rights,  contracts,  commitments  or  arrangements  obligating  the
Company to redeem, purchase or acquire, or offer to purchase, redeem or acquire,
any outstanding shares of, or any outstanding options, warrants or rights of any
kind  to  acquire  any  shares  of,  or  any  outstanding  securities  that  are

Company.

          (c) SUBSIDIARIES.  The Company owns,  directly or indirectly,  100% of
the  outstanding  shares of capital stock of each of its  Subsidiaries  free and
clear of any  Security  Interest  and each such share of capital  stock has been
duly authorized and is validly issued, fully paid and nonassessable, and none of
such shares of capital  stock has been issued in violation of any  preemptive or
similar right. No shares of capital stock of, or other equity  interests in, any
Subsidiary of the Company are reserved for issuance, and there are no contracts,
agreements,  commitments  or  arrangements  obligating the Company or any of its
Subsidiaries (i) to offer, sell, issue,  grant,  pledge,  dispose of or encumber

                                     - 13 -
<PAGE>

convertible  into or exchangeable  for, any shares of capital stock of, or other
equity interests in, any of the Subsidiaries of the Company.

          (d) VOTING ARRANGEMENTS. Except as set forth in ss.3(d) of the Company
Disclosure  Letter or in Company  Reports filed prior to the date hereof,  there
are no voting trusts,  proxies or other similar  agreements or understandings to
which the Company or any of its  Subsidiaries is a party or by which the Company
or any of its  Subsidiaries is bound with respect to the voting of any shares of

registration of the offering, sale or delivery of any shares of capital stock of
the Company or any of its  Subsidiaries  under the Securities  Act. There are no
issued or outstanding  bonds,  debentures,  notes or other  indebtedness  of the
Company  having the right to vote on any  matters on which  stockholders  of the

Merger  unless and until it receives the Requisite  Stockholder  Approval of the
Company Stockholders.

          (f)  NONCONTRAVENTION.  Neither the execution and the delivery of this
Agreement,  nor the consummation of the transactions  contemplated  hereby, will

under any agreement,  contract, lease, license,  instrument or other arrangement
to which the  Company  or any of its  Subsidiaries  is a party or by which it is
bound or to which any of its  assets is  subject,  except  where the  violation,
conflict,   breach,   default,    acceleration,    termination,    modification,
cancellation, or failure to give notice would not reasonably be expected to have
a Company  Material  Adverse  Effect or  except as set forth in  ss.3(f)  of the
Company  Disclosure  Letter.  Other than as required under the provisions of the
Hart-Scott-Rodino   Act,   Foreign   Competition   Laws,  the  Delaware  General

SEC  that  it has  been  required  to  make  under  the  Securities  Act and the
Securities  Exchange  Act  (collectively,  the "COMPANY  REPORTS").  Each of the
Company Reports has complied with the Securities Act and the Securities Exchange
Act in  all  material  respects.  None  of  the  Company  Reports,  as of  their
respective  dates,  contained any untrue statement of a material fact or omitted
to state a material fact necessary in order to make the statements made therein,
in light of the circumstances under which they were made, not misleading.

Disclosure  Letter or in Company  Reports  filed prior to the date  hereof,  the
Company and its  Subsidiaries  are in compliance  with all  applicable  foreign,

payment of all Taxes  required to be paid in respect of the  periods  covered by

          "COMPANY  BENEFIT  PLAN")  are  accurately  and  completely  listed in
          ss.3(o) of the Company Disclosure Letter. No Company Benefit Plan is a
          multi-employer  plan,  money  purchase  plan,  defined  benefit  plan,
          multiple employer plan or multiple employer welfare arrangement and no
          Company  Benefit  Plan is  covered  by  Title  IV of  ERISA.  True and
          complete  copies of all Company  Benefit Plans (other than medical and
          other similar  welfare plans made  generally  available to all Company
          Employees) have been made available to Parent.

               (ii) All Company  Benefit  Plans to the extent  subject to ERISA,
          are in  compliance  in all material  respects with ERISA and the rules
          and  regulations  promulgated  thereunder.  Each Company  Benefit Plan
          which is an  "employee  pension  benefit  plan"  within the meaning of
          Section 3(2) of ERISA  ("COMPANY  PENSION PLAN") and which is intended
          to be qualified  under Section 401(a) of the Internal  Revenue Code of
          1986, as amended (the "CODE"), has received a favorable  determination
          letter from the Internal Revenue Service,  which determination  letter
          is currently in effect,  and there are no  proceedings  pending or, to
          the  knowledge of the  management of the Company,  threatened,  or any
          facts or circumstances  known to the management of the Company,  which
          are  reasonably  likely to result in revocation of any such  favorable
          determination  letter. There is no pending or, to the knowledge of the
          management  of the  Company,  threatened  litigation  relating  to the
          Company Benefit Plans. Neither the Company nor any of its Subsidiaries
          has engaged in a transaction  with respect to any Company Benefit Plan
          that,  assuming the taxable period of such  transaction  expired as of
          the date hereof, is reasonably likely to subject the Company or any of
          its Subsidiaries to a tax or penalty imposed by either Section 4975 of
          the Code or Section 502(i) of ERISA.

               (iii)  No  liability  under  Title  IV of  ERISA  has  been or is
          reasonably  likely  to be  incurred  by  the  Company  or  any  of its
          Subsidiaries with respect to any ongoing, frozen or terminated Company
          Benefit Plan that is a "single-employer  plan",  within the meaning of
          Section 4001(a)(15) of ERISA,  currently or formerly maintained by any
          of them, or the single-employer plan of any entity which is considered
          a  predecessor  of the Company or one employer  with the Company under
          Section 4001 of ERISA (a "COMPANY ERISA AFFILIATE"). All contributions
          required to be made under the terms of any Company  Benefit  Plan have
          been  timely made or  reserves  therefor  on the balance  sheet of the
          Company have been established,  which reserves are adequate. Except as
          required by Part 6 of Title I of ERISA,  the Company does not have any
          unfunded  obligations  for retiree  health and life benefits under any
          Company Benefit Plan.

          (p) DELAWARE  GENERAL  CORPORATION LAW. For purposes of Section 203 of
the  Delaware  General  Corporation  Law,  the  execution  and  delivery of this
Agreement  and the  Stockholder  Agreements  and  consummation  of  transactions
contemplated  hereby and thereby,  including without  limitation the purchase by
Parent of Company Shares or other securities issued by the Company, has received
the prior  approval of the Board of Directors  of the Company and,  accordingly,
Parent will not be subject to the restrictions of Section 203(b) of the Delaware
General  Corporation Law in the  consummation of the Merger or this Agreement or
the Stockholder Agreements or the transactions contemplated by either thereof.

Reports,  the Company's products and information systems are Year 2000 Compliant
except to the extent  that their  failure to be Year 2000  Compliant  would not,
individually  or in the  aggregate,  reasonably  be  expected to have a material
adverse effect on the business,  financial condition or results of operations of
the  Company  and its  Subsidiaries  taken  as a  whole.  For  purposes  of this
Agreement,  "YEAR  2000  COMPLIANT"  shall  mean that a  Person's  products  and
information  systems



                                     - 18 -

electromagnetic fields or microwave transmissions); (vi) neither the Company nor
any of its Subsidiaries is subject to any orders, decrees,  injunctions or other
arrangements  with  any  governmental  or  regulatory   authority  of  competent
jurisdiction  or is subject to any indemnity or other  agreement  with any third
party relating to liability under any Environmental Law or relating to Hazardous
Substances;  and (vii) there are no  circumstances  or conditions  involving the
Company or any of its  Subsidiaries  that would reasonably be expected to result
in  any  claims,  liabilities,  investigations,  costs  or  restrictions  on the
ownership,   use  or  transfer  of  any  of  its  properties   pursuant  to  any
Environmental Law.

individually  or in the  aggregate,  a material  adverse effect on the business,
financial  condition or results of operation of the Company and its Subsidiaries
taken as a whole.

Disclosure  Letter,  all  material  contracts to which the Company or any of its

     4. REPRESENTATIONS AND WARRANTIES OF PARENT AND THE PARENT SUBSIDIARY. Each
of Parent and the Parent Subsidiary represents and warrants to the Company:

          (a)  ORGANIZATION,  QUALIFICATION  AND CORPORATE POWER. Each of Parent
and Parent  Subsidiary has been duly  incorporated  and is validly existing as a
corporation  in good



                                     - 20 -
<PAGE>

standing under the laws of the State of Delaware. If applicable to such country,
each  of  Parent's  Subsidiaries   operating  in  such  country  has  been  duly
incorporated or otherwise  organized,  is validly existing and, in jurisdictions
where  the  concept  is  applicable,  in good  standing  under  the  laws of the
jurisdiction  of its  incorporation  or  organization.  Each of  Parent  and its
Subsidiaries is duly  authorized to conduct  business and, if applicable to such
country,  is in good  standing  under the laws of each  jurisdiction  where such
qualification  is  required,  except  where  the lack of such  qualification  or
failure  to be in good  standing  would not  reasonably  be  expected  to have a
material  adverse  effect on the  business,  financial  condition  or results of
operations of Parent and its Subsidiaries  taken as a whole or on the ability of
the Parties to consummate  the  transactions  contemplated  by this Agreement (a
"Parent Material Adverse Effect").  Each of Parent and its Subsidiaries has full
corporate power and corporate  authority,  and all foreign,  federal,  state and
local  governmental  permits,  licenses and  consents,  required to carry on the
businesses  in which it is engaged and to own and use the  properties  owned and
used by it, except for such permits,  licenses and consents the failure of which
to have would not  reasonably  be  expected  to have a Parent  Material  Adverse
Effect. Parent does not own any equity interest in any corporation, partnership,
limited  liability  company,  joint  venture  or  other  entity  other  than the
Subsidiaries  listed in ss.4(a) of Parent's  disclosure letter accompanying this
Agreement (the "PARENT DISCLOSURe LETTER").

          (b)  CAPITALIZATION.  The entire  authorized  capital  stock of Parent
consists of 1,281,958 shares of preferred stock,  $.01 par value per share, none

32,601,087  Parent Shares were issued and  outstanding as of August 23, 1999 and
no Parent Shares were held in treasury on August 23, 1999. All of the issued and
outstanding  Parent  Shares have been duly  authorized  and are validly  issued,
fully paid and  nonassessable,  and none have been  issued in  violation  of any
preemptive  or  similar  right.  Except as set forth in  ss.4(b)  of the  Parent
Disclosure  Letter,   neither  Parent  nor  any  of  its  Subsidiaries  has  any
outstanding or authorized  Stock Rights.  There are no outstanding or authorized
stock appreciation,  phantom stock, profit  participation or similar rights with
respect to Parent or any of its  Subsidiaries.  There are no rights,  contracts,
commitments or  arrangements  obligating  Parent or any of its  Subsidiaries  to
redeem,  purchase  or acquire,  or offer to  purchase,  redeem or  acquire,  any
outstanding  shares of, or any  outstanding  options,  warrants or rights of any
kind  to  acquire  any  shares  of,  or  any  outstanding  securities  that  are
convertible into or exchangeable for any shares of, capital stock of Parent.

          (c)  SUBSIDIARIES.  Except  as set  forth  in  ss.4(a)  of the  Parent
Disclosure Letter, Parent, directly or indirectly,  owns 100% of the outstanding
shares  of  capital  stock of each of its  Subsidiaries  free  and  clear of any
Security  Interest and each such share of capital stock has been duly authorized
and is validly issued, fully paid and nonassessable,  and none of such shares of
capital stock has been issued in violation of any  preemptive or similar  right.
No shares of capital stock of, or other equity  interests in, any  Subsidiary of
Parent  are  reserved  for  issuance,  and there are no  contracts,  agreements,
commitments or arrangements  obligating Parent or any of its Subsidiaries (i) to
offer, sell, issue, grant, pledge,  dispose of or encumber any shares of capital
stock of, or other equity  interests  in, or any options,  warrants or rights of
any kind to acquire any shares of capital  stock of, or other  equity  interests
in, any of the Subsidiaries of Parent or (ii) to redeem, purchase or acquire, or
offer to purchase or acquire,  any  outstanding  shares of capital  stock of, or
other equity interests in, or any outstanding options, warrants or rights of any
kind to acquire any shares of capital stock of, or other equity  interest in, or
any outstanding  securities



                                     - 21 -
<PAGE>

that are convertible  into or exchangeable  for, any shares of capital stock of,
or other equity interests in, any of the Subsidiaries of Parent.

          (d) VOTING ARRANGEMENTS.  There are no voting trusts, proxies or other
similar  agreements or understandings to which Parent or any of its Subsidiaries
is a party or by which Parent or any of its  Subsidiaries  is bound with respect
to  the  voting  of  any  shares  of  capital  stock  of  Parent  or  any of its
Subsidiaries.  There are no issued or outstanding  bonds,  debentures,  notes or
other  indebtedness  of Parent  having the right to vote on any matters on which
stockholders of Parent may vote.

          (e)  AUTHORIZATION  OF  TRANSACTION.  Each of  Parent  and the  Parent
Subsidiary  has full power and authority  (including  full  corporate  power and
corporate authority),  and has taken all required action,  necessary to properly
execute and deliver this Agreement and to perform its obligations hereunder, and
this Agreement  constitutes the valid and legally binding  obligation of each of
Parent and the Parent  Subsidiary,  enforceable in accordance with its terms and
conditions,  except  as  limited  by  (i)  applicable  bankruptcy,   insolvency,
reorganization,  moratorium  and other  laws of  general  application  affecting
enforcement  of  creditors'  rights  generally  and (ii) general  principles  of
equity,  regardless  of whether  asserted in a  proceeding  in equity or at law;
provided,  however, that Parent cannot consummate the Merger unless and until it
receives the Requisite Stockholder Approval of the Parent Stockholders.

          (f)  NONCONTRAVENTION.  Neither the execution and the delivery of this
Agreement,  nor the consummation of the transactions  contemplated  hereby, will
(i) violate any constitution,  statute, regulation, rule, injunction,  judgment,
order,  decree or other  restriction of any Government Entity to which Parent or
any of its Subsidiaries is subject or any provision of the charter or by-laws of
Parent or any of its Subsidiaries or (ii) conflict with,  result in a breach of,
constitute a default under,  result in the  acceleration of, create in any party
the right to accelerate, terminate, modify or cancel or require any notice under
any agreement,  contract,  lease,  license,  instrument or other  arrangement to
which  either  Parent  or any of its  Subsidiaries  is a party or by which it is
bound or to which  any of its  assets is  subject,  except in the case of clause
(ii) where the violation, conflict, breach, default, acceleration,  termination,
modification,  cancellation  or failure to give notice would not  reasonably  be
expected to have a Parent Material Adverse Effect.  Other than as required under
the provisions of the  Hart-Scott-Rodino  Act, Foreign Competition Laws, Nasdaq,
the  Securities  Exchange Act, the  Securities  Act and state  securities  laws,
neither Parent nor any of its Subsidiaries needs to give any notice to, make any
filing with or obtain any  authorization,  consent or approval of any Government
Entity in order for the Parties to consummate the  transactions  contemplated by
this  Agreement,  except where the failure to give notice,  to file or to obtain
any authorization,  consent or approval would not reasonably be expected to have
a Parent Material Adverse Effect or except as set forth in ss.4(f) of the Parent
Disclosure Letter.  "Required Parent Consents" means any authorization,  consent
or approval of a Government  Entity or other Third Party required to be obtained
pursuant to any Foreign  Competition  Laws or state securities laws or so that a
matter  set  forth in ss.  4(f) of the  Parent  Disclosure  Letter  would not be
reasonably  expected to have a Parent  Material  Adverse  Effect for purposes of
this ss.4(f).

          (g) Filings  with the SEC.  Parent has made all  filings  with the SEC
that it has been required to make under the  Securities  Act and the  Securities
Exchange Act (collectively,



                                     - 22 -
<PAGE>

the  "Parent  Reports").  Each of the  Parent  Reports  has  complied  with  the
Securities Act and the Securities Exchange Act in all material respects. None of
the Parent Reports, as of their respective dates, contained any untrue statement
of a material  fact or omitted to state a material  fact  necessary  in order to
make the statements made therein, in light of the circumstances under which they
were made, not misleading.

          (h) FINANCIAL STATEMENTS.

               (i) Parent has filed an Annual  Report on Form 10-K (the  "PARENT
          10-K") for the fiscal  year ended  December  31,  1998 and a Quarterly
          Report on Form 10-Q (the "PARENT  10-Q") for the fiscal  quarter ended
          June 30, 1999.  The financial  statements  included in the Parent 10-K
          and the Parent 10-Q  (including the related notes and schedules)  have
          been   prepared   from  the  books  and  records  of  Parent  and  its
          Subsidiaries  in  accordance  with GAAP applied on a consistent  basis
          throughout  the periods  covered  thereby,  and present  fairly in all
          material   respects  the   financial   condition  of  Parent  and  its
          Subsidiaries  as of the indicated  dates and the results of operations
          and cash  flows of Parent and its  Subsidiaries  for the  periods  set
          forth therein,  (subject in the case of quarterly financial statements
          to the absence of complete  footnotes  and subject to normal  year-end
          audit adjustments).

               (ii) From June 30, 1999 until the date of this Agreement,  Parent
          and its  Subsidiaries  have not incurred any liabilities that are of a
          nature that would be required to be  disclosed  on a balance  sheet of
          Parent and its  Subsidiaries  or the  footnotes  thereto  prepared  in
          conformity  with GAAP,  other  than (A)  liabilities  incurred  in the
          ordinary  course  of  business  or (B)  liabilities  that  would  not,
          individually  or in the  aggregate,  reasonably  be expected to have a
          Parent Material Adverse Effect or (C) liabilities disclosed in ss.4(h)
          of the Parent  Disclosure  Letter or in Parent  Reports filed prior to
          the date hereof.

          (m) TAXES.  Except as set forth in  ss.4(m)  of the Parent  Disclosure
Letter or in Parent  Reports filed prior to the date hereof,  Parent and each of
its Subsidiaries  have duly filed or caused to be duly filed on their behalf all
federal,  state, local and foreign Tax Returns required to be filed by them, and
have duly paid, caused to be paid or made adequate  provision for the payment of
all Taxes  required  to be paid in  respect of the  periods  covered by such Tax
Returns,  except  where the  failure to file such Tax  Returns or pay such Taxes
would not  reasonably  be  expected to have a material  adverse  effect upon the
business,  financial  condition  or  results  of  operations  of Parent  and its
Subsidiaries  taken as a whole.  Except as set forth in  ss.4(m)  of the  Parent
Disclosure  Letter, no claims for Taxes have been asserted against Parent or any
of its Subsidiaries and no material  deficiency for any Taxes has been proposed,
asserted  or  assessed  which  has not been  resolved  or paid in  full.  To the
knowledge of Parent's  management,  no Tax Return or taxable period of Parent or
any of its  Subsidiaries  is under  examination  by any  taxing  authority,  and
neither Parent nor any of its  Subsidiaries  has received  written notice of any
pending audit by any taxing  authority.  There are no outstanding  agreements or
waivers  extending  the  statutory  period of  limitation  applicable to any Tax
Return for any period of Parent or any or its Subsidiaries.  Except as set forth
in ss.4(m) of the Parent  Disclosure  Letter,  there are no tax liens other than
liens  for  Taxes  not yet due and  payable  relating  to  Parent  or any of its
Subsidiaries.  Parent has no reason to believe  that any  conditions  exist that
could  reasonably  be  expected  to prevent  the  Merger  from  qualifying  as a
reorganization  within the meaning of Section 368(a) of the Code. Neither Parent
nor any of its  Subsidiaries is a party to any agreement or contract which would
result in payment  of any  "excess  parachute  payment"  within



                                     - 24 -
<PAGE>

the  meaning  of  Section  280G of the  Code  as a  result  of the  transactions
contemplated  hereby.  Neither Parent nor any of its  Subsidiaries has filed any
consent  pursuant  to  Section  341(f)  of the Code or  agreed  to have  Section
341(f)(2) of the Code apply to any  disposition  of a subsection (f) asset owned
by Parent or any of its  Subsidiaries.  Parent  has not been and is not a United
States real  property  holding  company (as defined in Section  897(c)(2) of the
Code) during the applicable period specified in Section  897(c)(1)(A)(ii) of the
Code. None of Parent or its Subsidiaries (x) has been a member of an "affiliated
group,"  within the meaning of Section  1504(a) of the Code,  other than a group
the common  parent of which was Parent or (y) has any liability for the Taxes of
any  person,  other  than  any of  Parent  or its  Subsidiaries  under  Treasury
Regulation ss.1.1502-6 (or any similar provision of state, local or foreign law)
as a transferee, successor, by contract or otherwise.

          (n)  FAIRNESS  OPINION.  ING Barings LLC has  delivered  to the Parent
Board the Parent Fairness Opinion, and a true and complete copy thereof has been
furnished to the Company.

          (o) EMPLOYEE BENEFITS.

               (i) All pension, profit-sharing,  deferred compensation, savings,
          stock bonus and stock option plans,  and all employee  benefit  plans,
          whether or not covered by ERISA which are  sponsored  by Parent or any
          Parent ERISA Affiliate (as defined below) of Parent or to which Parent
          or any Parent ERISA Affiliate of Parent makes contributions, and which
          cover employees of Parent (the "PARENT EMPLOYEES") or former employees
          of Parent,  all  employment  or  severance  contracts  with  executive
          officers of Parent,  and any applicable "change of control" or similar
          provisions in any plan,  contract or arrangement  that cover Employees
          (collectively,  "PARENT  BENEFIT  PLANS"  and  individually  a "PARENT
          BENEFIT PLAN") are accurately and completely  listed  inss.4(o) of the
          Parent  Disclosure  Letter. No Parent Benefit Plan is a multi-employer
          plan,  money purchase plan,  defined benefit plan,  multiple  employer
          plan or multiple  employer  welfare  arrangement and no Parent Benefit
          Plan is covered by Title IV of ERISA.  True and complete copies of all
          Parent  Benefit  Plans (other than medical and other  similar  welfare
          plans made generally available to all Parent Employees) have been made
          available to the Company.

               (ii) All Parent Benefit Plans to the extent subject to ERISA, are
          in  compliance  in all material  respects with ERISA and the rules and
          regulations promulgated thereunder.  Each Parent Benefit Plan which is
          an "employee  pension benefit plan" within the meaning of Section 3(2)
          of ERISA ("PARENT PENSION PLAN") and which is intended to be qualified
          under   Section   401(a)  of  the  Code,   has  received  a  favorable
          determination   letter  from  the  Internal  Revenue  Service,   which
          determination  letter  is  currently  in  effect,  and  there  are  no
          proceedings  pending or, to the knowledge of the management of Parent,
          threatened,  or any facts or circumstances  known to the management of
          Parent,  which are  reasonably  likely to result in  revocation of any
          such favorable  determination  letter.  There is no pending or, to the
          knowledge of the management of Parent,  threatened litigation relating
          to  the  Parent  Benefit   Plans.   Neither  Parent



                                     - 25 -
<PAGE>

          nor any of its  Subsidiaries has engaged in a transaction with respect
          to any Parent  Benefit Plan that,  assuming the taxable period of such
          transaction  expired as of the date hereof,  is  reasonably  likely to
          subject Parent or any of its  Subsidiaries to a tax or penalty imposed
          by either Section 4975 of the Code or Section 502(i) of ERISA.

               (iii)  No  liability  under  Title  IV of  ERISA  has  been or is
          reasonably  likely to be incurred by Parent or any of its Subsidiaries
          with respect to any ongoing,  frozen or terminated Parent Benefit Plan
          that is a  "single-employer  plan",  within  the  meaning  of  Section
          4001(a)(15) of ERISA, currently or formerly maintained by any of them,
          or the  single-employer  plan of any  entity  which  is  considered  a
          predecessor  of Parent or one employer  with Parent under Section 4001
          of ERISA (a "PARENT ERISA AFFILIATE").  All contributions  required to
          be made under the terms of any Parent  Benefit  Plan have been  timely
          made or reserves  therefor  on the  balance  sheet of Parent have been
          established, which reserves are adequate. Except as required by Part 6
          of Title I of ERISA, Parent does not have any unfunded obligations for
          retiree health and life benefits under any Parent Benefit Plan.

          (p) YEAR 2000.  Except as  disclosed  in the  previously  filed Parent
Reports,  Parent's  products  and  information  systems are Year 2000  Compliant
except to the extent  that their  failure to be Year 2000  Compliant  would not,
individually  or in the  aggregate,  reasonably  be  expected to have a material
adverse effect on the business,  financial condition or results of operations of
Parent and its Subsidiaries taken as a whole.

          (q) ENVIRONMENTAL MATTERS.  Except for such matters that, individually
or in the aggregate, are not reasonably likely to have a material adverse effect
on the business,  financial condition or results of operations of Parent and its
Subsidiaries  taken  as a whole,  or  would  not  otherwise  require  disclosure
pursuant to the Securities  Exchange Act, or are listed in ss.4(q) of the Parent
Disclosure Letter or described in Parent Reports filed prior to the date hereof,
(i) each of Parent and its  Subsidiaries  has complied and is in compliance with
all  applicable  Environmental  Laws;  (ii) the  properties  currently  owned or
operated by Parent or any of its  Subsidiaries  (including  soils,  groundwater,
surface  water,  buildings  or  other  structures)  are  not  contaminated  with
Hazardous  Substances  (as defined  below);  (iii) neither Parent nor any of its
Subsidiaries  is subject to liability  for any Hazardous  Substance  disposal or
contamination  on any third party  property;  (iv) neither Parent nor any or its
Subsidiaries  has  had  any  release  or  threat  of  release  of any  Hazardous
Substance;  (v) neither  Parent nor any of its  Subsidiaries  has  received  any
notice,  demand,  threat, letter, claim or request for information alleging that
it or  any of its  Subsidiaries  may be in  violation  of or  liable  under  any
Environmental  Law (including any claims relating to  electromagnetic  fields or
microwave  transmissions);  (vi) neither Parent nor any of its  Subsidiaries  is
subject to any  orders,  decrees,  injunctions  or other  arrangements  with any
governmental or regulatory authority of competent  jurisdiction or is subject to
any  indemnity  or other  agreement  with any third party  relating to liability
under any Environmental Law or relating to Hazardous Substances; and (vii) there
are no circumstances  or conditions  involving Parent or any of its Subsidiaries
that  could  reasonably  be  expected  to  result  in any  claims,  liabilities,
investigations,  costs or restrictions on the ownership,  use or transfer of any
of its properties pursuant to any Environmental Law.

          (r)  INTELLECTUAL  PROPERTY.  Except as  disclosed  in  ss.4(r) of the
Parent  Disclosure  Letter  or in the  Parent  Reports  filed  prior to the date
hereof,  Parent and its Subsidiaries have all right, title and interest in, or a
valid and binding license to use, all Parent  Intellectual  Property (as defined
below). Except as disclosed in ss.4(r) of the Parent Disclosure Letter or in the
Parent Reports filed prior to the date hereof,  Parent and its  Subsidiaries (i)
have not  defaulted in any material  respect under any license to use any Parent
Intellectual Property,  (ii) are not the subject of any proceeding or litigation
for  infringement  of any  third  party  intellectual  property,  (iii)  have no
knowledge of circumstances that would be reasonably expected to give rise to any
such proceeding or litigation and (iv) have no knowledge of  circumstances  that
are causing or would be  reasonably  expected to cause the loss or impairment of
any Parent Intellectual Property, other than a default, proceeding,  litigation,
loss or  impairment  that is not having or would not be  reasonably  expected to
have,  individually  or in the  aggregate,  a  material  adverse  effect  on the
business,  financial  condition  or  results  of  operation  of  Parent  and its
Subsidiaries taken as a whole.

          For purposes of this Agreement,  "PARENT INTELLECTUAL  PROPERTY" means
patents and patent  rights,  trademarks  and trademark  rights,  trade names and
trade name  rights,  service  marks and  service  mark  rights,  copyrights  and
copyright rights,  trade secret and trade secret rights,  and other intellectual
property rights,  and all pending  applications for and  registrations of any of
the foregoing that are individually or in the aggregate  material to the conduct
of the business of Parent and its Subsidiaries taken as a whole.

          (s) INSURANCE. Except as set forth in ss.4(s) of the Parent Disclosure
Letter,  each of  Parent  and  its  Subsidiaries  is  insured  with  financially
responsible  insurers in such  amounts and against  such risks and losses as are
customary for companies  conducting  the business as conducted by Parent and its
Subsidiaries during such time period.

          (t)  CERTAIN  CONTRACTS.  Except as set forth in ss.4(t) of the Parent
Disclosure  Letter, all material to which Parent or any of its Subsidiaries is a
party or may be bound that are required by Item  610(b)(10) of Regulation S-K to
be filed as exhibits to, or incorporated by reference in, the Parent 10-K or the
Parent  10-Q have  been so filed or  incorporated  by  reference.  All  material
contracts to which Parent or any of its  Subsidiaries is a party or may be bound
that have been  entered  into as of the date hereof and will be required by Item
610(b)(10)  of  Regulation  S-K to be filed or  incorporated  by reference  into
Parent's Quarterly Report on Form 10-Q for the period ending September 30, 1999,
but which have not previously  been filed or  incorporated by reference into any
Parent Reports,  are set forth in ss.4(t) of the Parent Disclosure  Letter.  All
contracts, licenses, consents, royalty or other agreements which are material to
Parent and its  Subsidiaries,  taken as a whole,  to which  Parent or any of its
Subsidiaries is a party (the "PARENT CONTRACTS") are valid and in full force and
effect on the date hereof except to the extent they have  previously  expired in
accordance  with  their  terms  or,  to the  extent  such  invalidity  would not
reasonably  be  expected  to have a  material  adverse  effect on the  business,
financial  condition  or results of  operations  of Parent and its  Subsidiaries
taken as a whole  and,  to  Parent's  knowledge,  neither  Parent nor any of its
Subsidiaries  has violated any  provision  of, or committed or failed to perform
any act which with or without notice,  lapse of time or both would  constitute a
default under the provisions of, any Parent Contract,  except for defaults which
individually  and in the aggregate would not reasonably be expected to result in
a material  adverse  effect on the business,



                                     - 27 -
<PAGE>

financial  condition  or results of  operations  of Parent and its  Subsidiaries
taken as a whole.

          (u)   ACTIVITIES  OF  PARENT   SUBSIDIARY.   Since  the  date  of  its
incorporation,  Parent  Subsidiary  has not carried on any business or conducted
any operations  other than the execution of this  Agreement,  the performance of
its obligations hereunder and matters ancillary thereto. Parent Subsidiary has a
positive net worth under GAAP.

          (v)  CIRCE.  Parent  and/or  its  Subsidiaries  have all Circe  Rights
necessary for the operation of Rings 1 and 2 of the Circe Network, except to the
extent the failure to have any such Circe Rights,  would not, in the  aggregate,
be reasonably  expected to have a Parent Material  Adverse Effect.  All material
Circe  Rights  relating  to Rings 1 and 2 have  terms or are  renewable  without
material cost, for the entire  expected  useful life of such rings.  To Parent's
knowledge, as of the date of this Agreement, there is no existing or anticipated
fact or circumstance that would be reasonably expected to cause a material delay
in the  scheduled  in-service  date of Circe Rings 3, 4 or 5 as described in the
most recent Parent Reports filed prior to the date hereof.

     5. COVENANTS.  The Parties agree as follows with respect to the period from
and after the  execution of this  Agreement  through and including the Effective
Time (except for ss.5(j),  ss.5(l) and ss.5(q),  which will apply from and after
the Effective Time in accordance with their  respective  terms and ss.5(p) which
will apply from the date hereof and shall survive after the Closing).

          (a) GENERAL.  Each of the Parties will use all  reasonable  efforts to
take all actions and to do all things  necessary in order to consummate and make
effective  the   transactions   contemplated   by  this   Agreement   (including
satisfaction,  but not  waiver,  of the  closing  conditions  set  forth in ss.6
below).

          (b) NOTICES AND CONSENTS. The Company and Parent will give any notices
(and will cause each of their  respective  Subsidiaries  to give any notices) to
third  parties,  and will use all  reasonable  efforts to obtain (and will cause
each of their respective  Subsidiaries to use all reasonable  efforts to obtain)
any  third-party  consents,  that may be required in connection with the matters
referred to in ss.3(f) and ss.4(f) above  (regardless  of whether the failure to
give such  notice or obtain  such  consent  would  result in a Company  Material
Adverse Effect or a Parent Material Adverse Effect).

          (c) REGULATORY  MATTERS AND APPROVALS.  Each of the Parties,  promptly
after the date hereof,  will (and the Company,  promptly  after the date hereof,
will cause each of its  Subsidiaries  to) give any  notices to, make any filings
with and use all reasonable efforts to obtain any  authorizations,  consents and
approvals of Government  Entities in connection with the matters  referred to in
ss.3(f) and ss.4(f) above. Without limiting the generality of the foregoing:

               (i) FEDERAL SECURITIES LAWS. As promptly as practicable following
          the  date  hereof,   Parent  and  the  Parent   Subsidiary  shall,  in
          cooperation   with  the  Company,   prepare  and  file  with  the  SEC
          preliminary  proxy  materials  which shall  constitute the Joint Proxy
          Statement/Prospectus   (such  proxy   statement/prospectus,   and  any
          amendments    or    supplements     thereto,    the    "JOINT    PROXY
          STATEMENT/PROSPECTUS")  and a registration  statement on Form S-4 with
          respect to



                                     - 28 -
<PAGE>

          the  issuance  of Parent  Shares in  connection  with the Merger  (the
          "REGISTRATION   STATEMENT"),    and   file   with   state   securities
          administrators such registration  statements or other documents as may
          be required under applicable blue sky laws to qualify or register such
          Parent  Shares in such states as are  designated  by the Company  (the
          "BLUE SKY  FILINGS").  The Joint  Proxy  Statement/Prospectus  will be
          included in the  Registration  Statement as Parent's  prospectus.  The
          Registration Statement and the Joint Proxy  Statement/Prospectus shall
          comply  as to  form  in all  material  respects  with  the  applicable
          provisions  of the  Securities  Act and the Exchange Act and the rules
          and regulations  thereunder.  Each of Parent and the Parent Subsidiary
          shall use all reasonable  efforts to have the  Registration  Statement
          declared  effective by the SEC as promptly as practicable after filing
          with the SEC and to keep the Registration  Statement effective as long
          as is  necessary  to  consummate  the  Merger.  Parent  and the Parent
          Subsidiary  agree  that  none  of the  information  supplied  or to be
          supplied  by  Parent  or  the  Parent   Subsidiary  for  inclusion  or
          incorporation  by reference in the  Registration  Statement and/or the
          Joint Proxy  Statement/Prospectus  and each  amendment  or  supplement
          thereto, at the time of mailing thereof and at the time of the Company
          Special  Meeting (as defined below) or the Parent Special  Meeting (as
          defined below), will contain an untrue statement of a material fact or
          omit to  state a  material  fact  required  to be  stated  therein  or
          necessary   to  make  the   statements   therein,   in  light  of  the
          circumstances under which they were made, not misleading.  The Company
          agrees that none of the information  supplied or to be supplied by the
          Company for inclusion or incorporation by reference in the Joint Proxy
          Statement/Prospectus  and each amendment or supplement thereto, at the
          time of mailing thereof and at the time of the Company Special Meeting
          or the Parent Special  Meeting,  will contain an untrue statement of a
          material  fact or omit to state a material  fact required to be stated
          therein or necessary to make the statements  therein,  in light of the
          circumstances under which they were made, not misleading. For purposes
          of  the  foregoing,  it is  understood  and  agreed  that  information
          concerning or related to Parent and the Parent Special Meeting will be
          deemed to have been supplied by Parent and  information  concerning or
          related to the Company and the Company Special Meeting shall be deemed
          to have been supplied by the Company.  Parent will provide the Company
          with a reasonable opportunity to review and comment on the Joint Proxy
          Statement/Prospectus  and any amendment or supplement thereto prior to
          filing such with the SEC,  will provide the Company with a copy of all
          such filings made with the SEC and will notify the Company as promptly
          as  practicable  after the receipt of any comments from the SEC or its
          staff or from any state securities  administrators  and of any request
          by the SEC or its staff or by any state securities  administrators for
          amendments or  supplements to the  Registration  Statement or any Blue
          Sky Filings or for additional information, and will supply the Company
          and its legal counsel with copies of all correspondence between Parent
          or any of its representatives, on the one hand, and the SEC, its staff
          or any  state  securities  administrators,  on the  other  hand,  with
          respect  to  the  Registration  Statement.  No  change,  amendment  or
          supplement to the information supplied by the Company for inclusion in
          the  Joint  Proxy  Statement/Prospectus  shall  be  made  without  the



                                     - 29 -
<PAGE>

          approval of the  Company,  which  approval  shall not be  unreasonably
          withheld or delayed.  If, at any time prior to the Effective Time, any
          event  relating  to the  Company or Parent or any of their  respective
          Affiliates,  officers or  directors  is  discovered  by the Company or
          Parent,  as the case may be, that is required by the  Securities  Act,
          the Securities  Exchange Act, or the rules or regulations  thereunder,
          to be set forth in an  amendment  to the  Registration  Statement or a
          supplement  to the Joint  Proxy  Statement/Prospectus,  the Company or
          Parent, as the case may be, will as promptly as practicable inform the
          other,  and such  amendment or supplement  will be promptly filed with
          the  SEC and  disseminated  to the  stockholders  of the  Company  and
          Parent,  to the extent  required by applicable  securities  laws.  All
          documents  which the  Company or Parent  files or is  responsible  for
          filing with the SEC and any other regulatory agency in connection with
          the Merger (including,  without limitation, the Registration Statement
          and the Joint Proxy  Statement/Prospectus)  will comply as to form and
          content in all material  respects  with the  provisions  of applicable
          law.  Notwithstanding the foregoing, the Company, on the one hand, and
          Parent  and  the  Parent  Subsidiary,  on  the  other  hand,  make  no
          representations or warranties with respect to any information that has
          been  supplied  in  writing  by the other,  or the  other's  auditors,
          attorneys  or  financial   advisors,   specifically  for  use  in  the
          Registration Statement or the Joint Proxy Statement/Prospectus,  or in
          any other  documents to be filed with the SEC or any other  regulatory
          agency   expressly  for  use  in  connection  with  the   transactions
          contemplated hereby.

               (ii) DELAWARE GENERAL  CORPORATION LAW. The Company will take all
          action, to the extent necessary in accordance with applicable law, its
          certificate of incorporation  and by-laws to convene a special meeting
          of its  stockholders  (the  "COMPANY  SPECIAL  MEETING"),  as  soon as
          reasonably practicable in order that the stockholders may consider and
          vote upon the  adoption  of this  Agreement  and the  approval  of the
          Merger in accordance with the Delaware General Corporation Law. Parent
          will take all  action,  to the extent  necessary  in  accordance  with
          applicable  law,  its  certificate  of  incorporation  and  by-laws to
          convene a special  meeting of its  stockholders  (the "PARENT  SPECIAL
          MEETING"),  as  soon as  reasonably  practicable  in  order  that  the
          stockholders  may consider and vote upon the issuance of Parent Shares
          in connection with the Merger as provided in the Agreement as required
          by the  rules  of  Nasdaq  and,  if  necessary,  an  amendment  to the
          certificate  of  incorporation  of Parent to  increase  the  number of
          authorized Parent Shares.  The Company and Parent shall mail the Joint
          Proxy    Statement/Prospectus   to   their   respective   stockholders
          simultaneously  and as  soon as  reasonably  practicable.  Subject  to

          thereby,  the term thereof is not extended thereby and the other terms
          and conditions thereof, taken as a whole, are not less advantageous to

          to exist any indebtedness,  issuances of debt securities,  guarantees,
          Security Interests,  loans or advances not in existence as of the date
          of this Agreement except pursuant to the credit facilities, indentures
          and other  arrangements in existence on the date of this Agreement and

          Agreement, in each case as such credit facilities,  indentures,  other
          arrangements and other existing indebtedness may be amended, extended,
          exchanged, modified, refunded, renewed or refinanced after the date of
          this Agreement,  but only if the aggregate principal amount thereof is
          not increased  thereby,  the term thereof is not extended  thereby and
          the other terms and conditions thereof, taken as a whole, are not less
          advantageous to Parent and its Subsidiaries than those in existence as
          of the date of this Agreement;

               (x)  without  Prior  Consultation,  Parent  will not  change  its
          methods  of  accounting  in  effect  at  June  30,  1999  in a  manner
          materially affecting the consolidated assets, liabilities or operating

          Consultation unless it has afforded Prior Consultation.

          In the event Parent shall request the Company to consent in writing to
an  action  otherwise  prohibited  by this  ss.  5(e),  the  Company  shall  use
reasonable  efforts to respond in a prompt and timely  fashion  (but in no event
later than ten (10) business days  following  such  request),  but may otherwise
respond affirmatively or negatively in its sole discretion.

          (f) ACCESS.  Each Party will (and will cause each of its  Subsidiaries
to) permit  representatives  of the other Party to have access at all reasonable
times and in a manner so as not to materially interfere with the normal business
operations of the Company and its Subsidiaries,  or Parent and its Subsidiaries,

to the others of any material adverse development causing a breach of any of its
own  representations and warranties in ss.3 and ss.4 above. No disclosure by any

          (h) COMPANY EXCLUSIVITY.

               (i) The  Company  shall,  and shall  cause its  Subsidiaries  and
          Representatives  to,  immediately  cease and  terminate  any  existing
          solicitation,   initiation,  encouragement,  activity,  discussion  or
          negotiation with any Persons conducted  heretofore by the Company, its
          Subsidiaries  or  any  of  their  respective   Affiliates,   officers,
          directors,  employees,  financial advisors,  agents or representatives
          (each a "REPRESENTATIVE")  with respect to any proposed,  potential or
          contemplated Acquisition Proposal.

               (ii) From and after the date  hereof,  without the prior  written
          consent of Parent, the Company will not authorize or permit any of its
          Subsidiaries  to, and shall  cause any and all of its  Representatives
          not to, directly or indirectly,  (A) solicit,  initiate,  or encourage
          any inquiries or proposals  that  constitute,  or could  reasonably be
          expected  to lead  to,  an  Acquisition  Proposal,  or (B)  engage  in
          negotiations  or  discussions  with any  Third  Party  concerning,  or
          provide any non-public  information  to any person or entity  relating
          to, an Acquisition  Proposal,  or (C) enter into any letter of intent,
          agreement in principle or any  acquisition  agreement or other similar
          agreement with respect to any Acquisition Proposal; provided, however,
          that nothing contained in thisss.5(h)(ii) shall prevent the Company or
          the  Company  Board  prior to  receipt  of the  Requisite  Stockholder
          Approval  of the  Company  Stockholders,  from  furnishing  non-public
          information to, or entering into discussions or negotiations with, any
          Third  Party in  connection  with an  unsolicited,  bona fide  written
          proposal for an Acquisition  Proposal by such Third Party, if and only
          to the extent that (1) such Third Party has made a written proposal to
          the Company  Board to  consummate  an  Acquisition  Proposal,  (2) the
          Company  Board  determines  in good faith,  based upon the advice of a
          financial  advisor  of  nationally  recognized  reputation,  that such
          Acquisition  Proposal  is  reasonably  capable of being  completed  on
          substantially the terms proposed, and would, if consummated, result in
          a transaction  that would provide  greater value to the holders of the
          Company Shares than the transaction  contemplated by this Agreement (a
          "SUPERIOR  PROPOSAL"),  (3) the failure to take such action would,  in
          the reasonable good faith judgment of the Company Board,  based upon a
          written  opinion of Company  outside legal counsel,  be a violation of
          its fiduciary  duties to the Company's  stockholders  under applicable
          law, and (4) prior to furnishing  such  non-public  information to, or
          entering into  discussions  or  negotiations  with,  such Person,  the
          Company Board  receives  from such Person an executed  confidentiality
          agreement  with material  terms no less  favorable to the Company than
          those  contained in the  Confidentiality  Agreement and provides prior
          notice of its decision to take such action to the Parent.  The Company
          agrees not to release any Third Party from, or waive any provision of,
          any standstill agreement to which it is a party or any confidentiality
          agreement  between  it and  another  Person  who has made,  or who may
          reasonably be  considered  likely to make,  an  Acquisition  Proposal,
          unless the failure to take such action would,  in the reasonable  good
          faith  judgment of the Company  Board,  based upon written  opinion of
          Company outside legal counsel,  be a violation of its fiduciary duties
          to the Company's  stockholders under applicable law and such action is
          taken prior to



                                     - 36 -
<PAGE>

          receipt  of  the  Requisite   Stockholder   Approval  of  the  Company
          Stockholders.  Without  limiting the foregoing,  it is understood that
          any violation of the restrictions set forth in the preceding  sentence
          by any  Representative of the Company or any of its Subsidiaries shall
          be deemed to be a breach of thisss.5(h) by the Company.

               (iii) The Company shall notify Parent  promptly  after receipt by
          the Company or the  Company's  knowledge  of the receipt by any of its
          Representatives  of  any  Acquisition  Proposal  or  any  request  for
          non-public  information in connection with an Acquisition  Proposal or
          for access to the  properties,  books or records of the Company by any
          Person that  informs such party that it is  considering  making or has
          made an Acquisition Proposal.  Such notice shall be made orally and in
          writing and shall  indicate  the identity of the offeror and the terms
          and conditions of such proposal, inquiry or contact. The Company shall
          keep  Parent  informed  of the  status  (including  any  change to the
          material  terms)  of any such  Acquisition  Proposal  or  request  for
          non-public information.

               (iv) The Company Board may not withdraw or modify,  or propose to
          withdraw or modify,  in a manner  adverse to Parent,  the  approval or
          recommendation  by the Company  Board of this  Agreement or the Merger
          unless,  following  the  receipt of a Superior  Proposal  and prior to
          receipt  of  the  Requisite   Stockholder   Approval  of  the  Company
          Stockholders,  in the  reasonable  good faith  judgment of the Company
          Board,  based upon the  written  opinion of  Company's  outside  legal
          counsel,  the  failure to do so would be a  violation  of the  Company
          Board's   fiduciary  duties  to  the  Company's   stockholders   under
          applicable  law;  provided,  however,  that,  the Company  Board shall
          submit this Agreement and the Merger to the Company's stockholders for
          adoption and  approval,  whether or not the Company  Board at any time
          subsequent  to the date hereof  determines  that this  Agreement is no
          longer  advisable or recommends  that the  stockholders of the Company
          reject it or  otherwise  modifies  or  withdraws  its  recommendation.
          Unless the Company  Board has  withdrawn  its  recommendation  of this
          Agreement  in  compliance  herewith,  the  Company  shall use its best
          efforts to solicit from the Company  stockholders  proxies in favor of
          the  adoption  and  approval of this  Agreement  and the Merger and to
          secure the vote or consent of the Company's  stockholders  required by
          the  Delaware   General   Corporation   Law  and  its  certificate  of
          incorporation  and by-laws to adopt and approve this Agreement and the
          Merger.

          (i) PARENT EXCLUSIVITY.

               (i)  Parent  shall,   and  shall  cause  its   Subsidiaries   and
          Representatives  to,  immediately  cease and  terminate  any  existing
          solicitation,   initiation,  encouragement,  activity,  discussion  or
          negotiation  with any  Persons  conducted  heretofore  by Parent,  its
          Subsidiaries  or  any  of  its  Representatives  with  respect  to any
          proposed,  potential or contemplated  Parent Acquisition  Proposal the
          consummation  of which would (x) not be consistent with this Agreement
          or  the



                                     - 37 -
<PAGE>

          Merger and the other transactions  contemplated by this Agreement, (y)
          result in a material delay in the Effective Time or (z) materially and
          adversely  impact the  likelihood  of obtaining  any Required  Company
          Consent or Required  Parent  Consent  other than those the failures to
          obtain would not result in either a Company Material Adverse Effect or
          a Parent  Material  Adverse Effect (a "PROHIBITED  PARENT  ACQUISITION
          PROPOSAL").

               (ii) From and after  the date  hereof,  Parent  will  notify  the
          Company of any Parent Acquisition Proposal of which notice is given to
          the Parent  Board.  Such notice to the Company  will be made  promptly
          after such notice to the Parent Board, but will be conditional upon an
          appropriate  confidentiality  agreement.  Without  the  prior  written
          consent of the Company, Parent will not authorize or permit any of its
          Subsidiaries  to, and shall  cause any and all of its  Representatives
          not to, directly or indirectly,  (A) solicit,  initiate,  or encourage
          any inquiries or proposals  that  constitute,  or could  reasonably be
          expected to lead to, a Prohibited Parent Acquisition  Proposal, or (B)
          engage in  negotiations  or  discussions  with any Parent  Third Party
          concerning,  or provide  any  nonpublic  information  to any person or
          entity relating to, a Prohibited Parent Acquisition  Proposal,  or (C)
          enter  into any  letter  of  intent,  agreement  in  principle  or any
          acquisition  agreement or other similar  agreement with respect to any
          Prohibited  Parent  Acquisition  Proposal;   provided,  however,  that
          nothing  contained  in  thisss.5(i)(ii)  shall  prevent  Parent or the
          Parent  Board  from,  prior to  receipt of the  Requisite  Stockholder
          Approval of the Parent Stockholders,  furnishing nonpublic information
          to, or entering into  discussions  or  negotiations  with,  any Parent
          Third  Party in  connection  with an  unsolicited,  bona fide  written
          proposal for a Prohibited Parent  Acquisition  Proposal by such Parent
          Third  Party,  if and only to the extent  that (1) such  Parent  Third
          Party has made a written  proposal to the Parent Board to consummate a
          Prohibited  Parent   Acquisition   Proposal,   (2)  the  Parent  Board
          determines in good faith, based upon the advice of a financial advisor
          of  nationally  recognized  reputation,  that such  Prohibited  Parent
          Acquisition  Proposal  is  reasonably  capable of being  completed  on
          substantially the terms proposed, and would, if consummated, result in
          a transaction  that would provide  greater value to the holders of the
          Parent Shares than the  transaction  contemplated by this Agreement (a
          "PARENT  SUPERIOR  PROPOSAL"),  (3) the  failure  to take such  action
          would,  in the  reasonable  good faith  judgment of the Parent  Board,
          based upon a written opinion of Parent's  outside legal counsel,  be a
          violation of its fiduciary duties to the Parent's  stockholders  under
          applicable law, and (4) prior to furnishing such nonpublic information
          to, or entering into  discussions or  negotiations  with, such Person,
          the Parent Board receives from such Person an executed confidentiality
          agreement  with material  terms no less favorable to Parent than those
          contained  in the  Confidentiality  Agreement.  Parent  agrees  not to
          release any Parent Third Party from,  or waive any  provision  of, any
          standstill  agreement  to which  it is a party or any  confidentiality
          agreement  between  it and  another  Person  who has made,  or who may
          reasonably  be  considered   likely  to  make,  a  Prohibited   Parent
          Acquisition Proposal, unless the failure to take such action would, in
          the reasonable good faith judgment of the Parent Board, based upon the
          written opinion of Parent's  outside legal counsel,  be a violation of
          its



                                     - 38 -
<PAGE>

          fiduciary duties to the Parent's stockholders under applicable law and
          such  action is taken  prior to receipt of the  Requisite  Stockholder
          Approval of the Parent  Stockholders.  Without limiting the foregoing,
          it is understood that any violation of the  restrictions  set forth in
          the preceding  sentence by any  Representative of Parent or any of its
          Subsidiaries  shall be  deemed to be a breach  of  thisss.5(i)(ii)  by
          Parent.  A Parent  Acquisition  Proposal  shall be deemed a Prohibited
          Parent  Acquisition  Proposal  at the time (and not before) the Parent
          Board is first notified of such Parent  Acquisition  Proposal,  and at
          any  time  that  the  Parent  Board  is  notified  of  a   significant
          development with respect to such Parent Acquisition  Proposal,  unless
          the Parent Board in good faith determines that such Parent Acquisition
          Proposal is not, and is not reasonably  likely to become, a Prohibited
          Parent Acquisition Proposal.

               (iii) Parent shall notify the Company  promptly  after receipt by
          Parent  or   Parent's   knowledge   of  the  receipt  by  any  of  its
          Representatives of any Prohibited Parent  Acquisition  Proposal or any
          request for  non-public  information  in connection  with a Prohibited
          Parent Acquisition Proposal or for access to the properties,  books or
          records of Parent by any  Person  that  informs  such party that it is
          considering  making  or  has  made  a  Prohibited  Parent  Acquisition
          Proposal.  Such  notice  shall be made orally and in writing and shall
          indicate the identity of the offeror and the terms and  conditions  of
          such  proposal,  inquiry or  contact.  Parent  shall keep the  Company
          informed of the status (including any change to the material terms) of
          any  such  Prohibited  Parent  Acquisition  Proposal  or  request  for
          nonpublic information.

               (iv) The Parent Board may not  withdraw or modify,  or propose to
          withdraw or modify,  in a manner adverse to the Company,  the approval
          or  recommendation by the Parent Board of this Agreement or the Merger
          unless,  following the receipt of a Parent Superior Proposal but prior
          to  receipt  of the  Requisite  Stockholder  Approval  of  the  Parent
          Stockholders,  in the  reasonable  good faith  judgment  of the Parent
          Board,  based upon the  written  opinion  of  Parent's  outside  legal
          counsel,  the  failure  to do so would be a  violation  of the  Parent
          Board's fiduciary duties to the Parent's stockholders under applicable
          law; provided,  however, that the Parent Board shall submit the Merger
          to Parent's stockholders for adoption and approval, whether or not the
          Parent Board at any time subsequent to the date hereof determines that
          this  Agreement  is  no  longer   advisable  or  recommends  that  the
          stockholders  of Parent  reject the Merger or  otherwise  modifies  or
          withdraws  its  recommendation.  Unless the Parent Board has withdrawn
          its recommendation of the Merger in compliance herewith,  Parent shall
          use its best efforts to solicit from the Parent  stockholders  proxies
          in favor of the  adoption and approval of the Merger and to secure the
          vote or consent of  Parent's  stockholders  required by Nasdaq and the
          Delaware General Corporation Law.

               (v)  Prior  to  taking  any  action  with  respect  to  a  Parent
          Acquisition  Proposal  which is not a  Prohibited  Parent  Acquisition
          Proposal  equivalent to those  permitted by clauses (A), (B) or (C) of
          ss.5(i)(ii),  Parent shall notify each



                                     - 39 -
<PAGE>

          Parent Third Party which is the object of or a party to such action of
          the limitation on Prohibited Parent Acquisition Proposals set forth in
          this  ss.5(i),  and Parent  shall not enter into any letter of intent,
          agreement in principle or any  acquisition  agreement or other similar
          agreement with respect to any Parent Acquisition  Proposal unless such
          letter or agreement includes a covenant of the applicable Parent Third
          Party not to take any action which would cause such Parent Acquisition
          Proposal to become a Prohibited Parent Acquisition Proposal.

          (j) INSURANCE AND INDEMNIFICATION.

               (i) Parent will provide each  individual who served as a director
          or officer of the Company at any time prior to the Effective Time with
          liability insurance for a period of six years after the Effective Time
          no less favorable in coverage and amount than any applicable insurance
          of the  Company  in effect  immediately  prior to the  Effective  Time
          provided,  however, if the existing liability insurance expires, or is
          terminated or canceled by the insurance  carrier  during such six year
          period, the Surviving  Corporation will use its best efforts to obtain
          as much liability  insurance (no less favorable in coverage) as can be
          obtained for the  remainder of such period for a premium not in excess
          (on an annualized basis) of 200% of the last annual premium paid prior
          to the date hereof.

               (ii) After the Effective Time, Parent (A) will not take or permit
          to be  taken  any  action  to  alter  or  impair  any  exculpatory  or
          indemnification   provisions  now  existing  in  the   certificate  of
          incorporation, by-laws or indemnification and employment agreements of
          the  Company  or  any of  its  Subsidiaries  for  the  benefit  of any
          individual  who served as a director  or officer of the Company or any
          of its Subsidiaries (an "INDEMNIFIED  PARTY") at any time prior to the
          Effective Time (except as may be required by applicable  law), and (B)
          shall  cause  the  Surviving  Corporation  to honor and  fulfill  such
          provisions  until the date which is six years from the Effective  Time
          (except as may be required by applicable law);  provided,  however, in
          the event any claim or claims are  asserted  within such  period,  all
          rights to  indemnification  in respect  of such claim or claims  shall
          continue until the final disposition thereof.

               (iii) To the extent clauses (i) and (ii) above shall not serve to
          indemnify and hold harmless an Indemnified Party,  Parent,  subject to
          the terms and conditions of this clause (iii),  will indemnify,  for a
          period of six years from the  Effective  Time,  to the fullest  extent
          permitted  under  applicable  law,  each  Indemnified  Party  from and
          against   any  and  all   actions,   suits,   proceedings,   hearings,
          investigations,  charges,  complaints,  claims, demands,  injunctions,
          judgments,  orders, decrees, rulings, damages, dues, penalties, fines,
          costs, amounts paid in settlement,  liabilities,  obligations,  taxes,
          liens,  losses,  expenses  and fees,  including  all  court  costs and
          reasonable  attorneys' fees and expenses,  resulting from, arising out
          of, relating to or caused by this Agreement or any of the transactions
          contemplated  herein;  provided,  however,  in the  event any claim or
          claims are asserted or  threatened  within such six-year  period,  all
          rights to



                                     - 40 -
<PAGE>

          indemnification  in respect of any such claim or claims shall continue
          until final  disposition of any and all such claims.  Any  Indemnified
          Party  wishing  to claim  indemnification  under  this  clause  (iii),
          notwithstanding  anything to the contrary in the  provisions set forth
          in the  Company's  certificate  of  incorporation,  by-laws  or  other
          agreements respecting  indemnification of directors or officers,  upon
          learning of any such claim, action, suit, proceeding or investigation,
          shall  promptly  notify Parent  thereof,  but the failure to so notify
          shall  not  relieve  Parent  of any  liability  it may  have  to  such
          Indemnified  Party  if such  failure  does  not  materially  prejudice
          Parent. In the event of any such claim,  action,  suit,  proceeding or
          investigation  (whether  arising before or after the Effective  Time),
          (A) Parent or the Surviving Corporation shall have the right following
          the Effective Time to assume the defense  thereof and Parent shall not
          be liable to such Indemnified  Parties for any legal expenses of other
          counsel  or  any  other   expenses   subsequently   incurred  by  such
          Indemnified  Parties in connection  with the defense  thereof,  except
          that if  Parent or the  Surviving  Corporation  fails to  assume  such
          defense or  counsel  for Parent  advises  that there are issues  which
          raise   conflicts  of  interest   between   Parent  or  the  Surviving
          Corporation,  on the one hand,  and the  Indemnified  Parties,  on the
          other hand, the Indemnified Parties may retain counsel satisfactory to
          them, and the Company,  Parent or the Parent  Subsidiary shall pay all
          reasonable  fees and  expenses  of such  counsel  for the  Indemnified
          Parties  promptly  as  statements  therefor  are  received;  provided,
          however,  that Parent  shall be  obligated to pay for only one firm of
          counsel for all Indemnified Parties in any jurisdiction unless the use
          of one counsel for such Indemnified Parties would present such counsel
          with a conflict  of  interest,  in which case Parent need only pay for
          separate counsel to the extent necessary to resolve such conflict; (B)
          the Indemnified  Parties will  reasonably  cooperate in the defense of
          any such matter; and (C) Parent shall not be liable for any settlement
          effectuated without its prior written consent, which consent shall not
          be  unreasonably  withheld  or  delayed.  Parent  shall not settle any
          action or claim  identified  in  thisss.5(j)(iii)  in any manner  that
          would impose any liability or penalty on an Indemnified Party not paid
          by  Parent  or the  Surviving  Corporation  without  such  Indemnified
          Party's prior written consent, which consent shall not be unreasonably
          withheld or delayed.

               (iv)  Notwithstanding  anything  contained in clause (iii) above,
          Parent  shall not have any  obligation  hereunder  to any  Indemnified
          Party (A) if the  indemnification  of such Indemnified Party by Parent
          in the manner contemplated hereby is prohibited by applicable law, (B)
          the conduct of the Indemnified  Party relating to the matter for which
          indemnification  is sought involved bad faith or willful misconduct of
          such  Indemnified  Party,  or (C) with respect to actions taken by any
          such Indemnified Party in his or its individual  capacity,  including,
          without limitations, with respect to any matters relating, directly or
          indirectly,  to the purchase,  sale or trading of securities issued by
          the Company  other than a tender or sale  pursuant  to a stock  tender
          agreement  or (D) if such  Indemnified  Party shall have  breached its
          obligation  to  cooperate  with  Parent in the defense of any claim in
          respect  of  which  indemnification  is  sought  and such  breach  (x)
          materially and adversely affects Parent's defense of such claim or (y)
          will materially and



                                     - 41 -
<PAGE>

          adversely  affect Parent's defense of such claim if such breach is not
          cured  within ten days after notice of such breach is delivered to the
          Indemnified Party and such breach is not cured during such period.

          (k) FINANCIAL STATEMENTS.

               (i) As soon as they are made  available to and reviewed by senior
          management of the Company,  the Company shall make available to Parent
          the  internally  generated  monthly,  quarterly  (including  quarterly
          statements for the  three-month  period ended  September 30, 1999) and
          annual financial statements of the Company, consisting of consolidated
          balance  sheets,  and  consolidated  statements  of income and of cash

          annual  financial  statements,   consisting  of  consolidated  balance
          sheets, and consolidated statements of income and of cash flows.

          (l) CONTINUITY OF BUSINESS ENTERPRISE.  Parent,  Surviving Corporation
or any other member of the  qualified  group (as defined in Treasury  Regulation
ss.1.368-1(d))  shall,  for  the  foreseeable  future,  continue  at  least  one
significant  historic business line of the Company or use at least a significant
portion of the Company's  historic  business assets in a business,  in each case
within the meaning of Treasury Regulation ss.1.368-1(d).

          (n) RULE 145 AFFILIATES.  Prior to the Closing Date, the Company shall
deliver to Parent a letter  identifying all persons who were, at the date of the
Company  Special  Meeting,  "affiliates" of the Company for purposes of Rule 145
under the Securities Act. The Company shall use its reasonable  efforts to cause
each such person to deliver to Parent on or prior to the Closing  Date a written
agreement substantially in the form attached as Exhibit C.

          (o) NASDAQ LISTING.  Parent shall use all reasonable  efforts to cause
the  Parent  Shares to be issued in  connection  with the  Merger  and under the
Company Benefit Plans to be approved for listing on Nasdaq,  subject to official
notice of issuance, prior to the Closing Date.

          (p) TAX FREE TREATMENT.  The Parties intend the Merger to qualify as a
reorganization  under Section 368(a) of the Code.  Each Party and its Affiliates
shall use reasonable efforts to cause the Merger to so qualify and to obtain the
opinion referred to in ss. 6(b)(vii).  For purposes of the tax opinion described
in ss. 6(b)(vii),  Parent and the Company shall provide customary representation
letters  substantially  in the form of  Exhibits D and E, each dated on or about
the  date  that  is  two  business  days  prior  to the  date  the  Joint  Proxy
Statement/Prospectus is mailed to the stockholders of Parent and the Company and
reissued as of the  Closing  Date.  Each of Parent,  Parent  Subsidiary  and the
Company and each of their  respective  Affiliates  shall not take any action and
shall not fail to take any action or suffer to exist any condition  which action
or failure to act or condition would prevent,  or would be reasonably  likely to
prevent,  the Merger from qualifying as a  reorganization  within the meaning of
Section 368(a) of the Code.

          (q) COMPANY  EMPLOYEE PLANS.  After the Effective  Time,  Parent shall
arrange for each employee  participating in any of the Company Benefits Plans to
participate in any counterpart  benefit plans of Parent or its  Subsidiaries (as
appropriate) in accordance with the eligibility criteria thereof,  provided that
(i) such  participants  shall  receive full credit for years of service with the
Company or any of its Subsidiaries  prior to the Effective Time for all purposes
for which such service was recognized  under the Company  Benefit Plans and (ii)
such participants shall participate in the Parent Benefit Plans on terms no less
favorable than those offered by Parent to similarly situated employees of Parent
or its  Subsidiaries.  Parent  shall give credit under its  applicable  employee
welfare benefit plans for all copayments, deductibles and out-of-pocket maximums
satisfied by employees (and their  eligible  dependents) of the Company (and its
Subsidiaries), in respect of the calendar year in which the Closing Date occurs.
Parent shall waive all  pre-existing  conditions (to the extent waived under the
applicable  employee welfare benefit plans of the Company and its  Subsidiaries)
otherwise  applicable  to  employees of the Company and its  Subsidiaries  under
Parent's  employee  welfare benefit plans in which employees of the Company (and
its  Subsidiaries)  become  eligible to participate on or following the Closing.
Notwithstanding  the  foregoing,  Parent may  continue  (or cause the  Surviving
Corporation to continue) one or more of the Company Benefit Plans, in which case
Parent  shall have  satisfied  its  obligations  hereunder  with  respect to the
benefits  so  provided  if the  terms of the  Company  Benefit  Plans  which are
continued  are no less  favorable  than the  terms of the  counterpart  plans of
Parent and its Subsidiaries (as applicable).

          (r) NOTICE OF ADVERSE CIRCE NETWORK  DEVELOPMENTS.  Parent will notify
Company  promptly after it becomes aware of any fact or circumstance  that would
be  reasonably  expected to  materially  delay or prevent the  completion in all
material  respects of the Circe



                                     - 43 -

prior to the date hereof.

          (s) DISCOUNT NOTES.  Parent and the Company agree to cooperate and use
their  reasonable  efforts to obtain  within 60 days  after the date  hereof any
necessary consents,  waivers or other modifications of the indenture dated as of
April 8,  1998,  between  the  Company  and The Bank of New  York,  as  trustee,
governing the 11% Senior Discount Notes due 2008 issued by the Company, so as to
avoid the  obligation  to conduct an Offer to Purchase  pursuant to Section 4.12
thereof as a result of the transactions contemplated by this Agreement, provided
that in  connection  with  obtaining  such  consents,  waivers or  modifications
neither  the Company nor Parent will be required to make any payment or take any
other action which is not commercially  reasonable.  The Company and Parent each
shall pay one-half of all fees and expenses,  including  fees paid to holders of
such notes,  incurred by the Parties pursuant to this ss.5(s).  If such consent,
waiver or modification  is not obtained  within such 60 day period,  the Parties
may  mutually  agree to modify the terms of this  Agreement so as to achieve the
results  of the  transactions  contemplated  hereby  in a manner  that  will not
require such an Offer to Purchase to be undertaken.

          (t) YEAR 2000 BUDGETS. Each of Parent and the Company shall, and shall
seek to cause its executive  officers to, (a) cooperate in good faith to develop
a year 2000  combined  budget for Parent and (b) provide such  assistance as the
other Party may reasonably require to develop a year 2000 combined budget.

Dear Sirs:

          The  undersigned  refers  to the  Agreement  and Plan of  Merger  (the
"MERGER AGREEMENT") dated as of August 27, 1999, among Viatel,  Inc., a Delaware
corporation,  Viatel  Acquisition  Corp.,  a  Delaware  corporation,  and Destia
Communications,  Inc., a Delaware  corporation.  Capitalized  terms used but not
defined  in this  letter  have the  meanings  given  such  terms  in the  Merger
Agreement.

          The  undersigned,  a holder of Company Shares,  is entitled to receive
Parent Shares in connection with the Merger.  The undersigned  acknowledges that
the  undersigned  may be deemed an "affiliate" of the Company within the meaning
of Rule 145 ("RULE 145")  promulgated under the Securities Act, although nothing
contained herein should be construed as an admission of such fact.

          If in fact the  undersigned  were an  affiliate  under  the  Act,  the
undersigned's  ability to sell, assign or transfer the Parent Shares received by
the undersigned in exchange for any Company Shares pursuant to the Merger may be
restricted  unless such  transaction is registered under the Act or an exemption
from such  registration is available.  The undersigned (i) understands that such
exemptions are limited and (ii) has obtained  advice of counsel as to the nature
and conditions of such  exemptions,  including  information  with respect to the
applicability to the sale of such securities of Rules 144 and 145(d) promulgated
under the Securities Act.

          The  undersigned  hereby  represents to and covenants with Parent that
the  undersigned  will not sell,  assign or  transfer  any of the Parent  Shares
received by the  undersigned  in exchange  for  Company  Shares  pursuant to the
Merger  except (i) pursuant to an  effective  registration  statement  under the
Securities  Act or (ii) in a  transaction  that,  in the opinion of  independent
counsel  (the  reasonable  fees of which  counsel  will be paid by Parent) or as
described in a "no-action" or interpretive  letter from the Staff of the SEC, is
not required to be registered under the Securities Act.

          In the  event  of a  sale  or  other  disposition  by the  undersigned
pursuant  to Rule 145,  of Parent  Shares  received  by the  undersigned  in the
Merger, the undersigned will supply Parent with evidence of compliance with such
Rule,  in the form of a letter in the form of Annex I hereto and the  opinion of
counsel or no-action letter referred to above. The undersigned  understands that
Parent may instruct  its  transfer  agent to withhold the transfer of any Parent
Securities  disposed  of by the  undersigned,  but  that  upon  receipt  of such
evidence of compliance the transfer  agent shall  effectuate the transfer of the
Parent Shares sold as indicated in the letter.

          The undersigned  acknowledges and agrees that appropriate legends will
be  placed  on any  certificates  representing  Parent  Shares  received  by the
undersigned in the Merger or held by a transferee thereof, which legends will be
removed by delivery of  substitute  certificates  upon


<PAGE>

receipt of an opinion in form and substance  reasonably  satisfactory  to Parent
from  independent  counsel (the reasonable fees of which counsel will be paid by
Parent) to the effect that such  legends are no longer  required for purposes of
the Securities Act.

          The  undersigned  acknowledges  that (i) the undersigned has carefully
read this letter and  understands  the  requirements  hereof and the limitations
imposed upon the distribution, sale, transfer or other disposition of the Parent
Shares and (ii) the  receipt  by Parent of this  letter is an  inducement  and a
condition to Parent's obligations to consummate the Merger.


                                        Very truly yours,

                          [Letterhead of VIATEL, INC.]




                                                                          , 1999

Ladies and Gentlemen:

          In  connection  with the opinion to be  delivered  pursuant to Section
6(b)(vii) of the Agreement and Plan of Merger (the "Merger  Agreement") dated as
of August 27, 1999, among VIATEL,  INC., a Delaware  corporation (the "Parent"),
VIATEL  ACQUISITION  CORP.,  a Delaware  corporation  and a direct  wholly owned
subsidiary of the Parent (the "Parent Subsidiary"),  and DESTIA  COMMUNICATIONS,
INC., a Delaware corporation (the "Company"),  and in connection with the filing
with the  Securities  and Exchange  Commission  (the "SEC") of the  registration
statement on Form S-4 (the "Registration  Statement"),  which includes the Joint
Proxy  Statement/Prospectus  of the  Parent  and the  Company,  the  undersigned
certifies and  represents on behalf of the Parent and the Parent  Subsidiary and
as to the Parent and the Parent Subsidiary, after due inquiry and investigation,
as follows (any  capitalized term used but not defined herein having the meaning
given to such term in the Merger Agreement):

          1.  The  facts  relating  to the  contemplated  merger  of the  Parent
Subsidiary  with  and  into the  Company  (the  "Merger")  as  described  in the
Registration Statement and the documents described in the Registration Statement
are,  insofar  as such facts  pertain  to the Parent and the Parent  Subsidiary,
true,  correct  and  complete  in all  material  respects.  The  Merger  will be
consummated in accordance with the Merger Agreement.

          2. The  formula  set forth in the Merger  Agreement  pursuant to which
each issued and  outstanding  share of voting common  stock,  par value $.01 per
share,  of the Company  (the "Voting  Shares")  and each issued and  outstanding
share of non-voting  common stock, par value $.01 per share, of the Company (the
"Nonvoting  Shares" and, together with the Voting Shares,  the "Company Shares")
will be converted into common shares of the Parent (the "Parent  Shares") is the
result of arm's length bargaining.


<PAGE>

          3. Cash payments to be made to  stockholders of the Company in lieu of
fractional  shares of  Parent  Shares  that  would  otherwise  be issued to such
stockholders in the Merger will be made for the purpose of saving the Parent the
expense and  inconvenience  of issuing  and  transferring  fractional  shares of
Parent Shares, and do not represent separately bargained for consideration.  The
total cash  consideration that will be paid in the Merger to stockholders of the
Company in lieu of fractional  shares of Parent Shares is not expected to exceed
one  percent  of the total  consideration  that will be issued in the  Merger to
stockholders of the Company in exchange for their shares of Company Shares.

          4. (i) The Parent  has no present  plan or  intention,  following  the
Merger, to reacquire,  or to cause any corporation that is related to the Parent
to acquire,  any Parent Shares,  except for  repurchases of Parent Shares by the
Parent in  connection  with a repurchase  program  meeting the  requirements  of
Section  4.05(1)(b) of Revenue  Procedure  96-30,  which program was not entered
into or amended in any way in contemplation of or connection with the Merger. To
the best  knowledge of the  management  of the Parent,  no  corporation  that is
related to the Parent has a plan or intention to purchase any Parent Shares.

          (ii) For purposes of this  representation  letter, a corporation shall
be treated as related to the Parent if such corporation is related to The Parent
within the meaning of Treasury Regulation Section 1.368-1(e)(3).

          5.  The  Parent  has  no  present   plan  or  intention  to  make  any
distributions after the Merger to holders of Parent Shares (other than dividends
made in the ordinary course of business).

          6.  Neither  the  Parent  nor the  Parent  Subsidiary  (nor any  other
subsidiary  of the Parent) has  acquired,  or, except as a result of the Merger,
will acquire, or has owned in the past five years, any Company Shares.

          7. Prior to the Merger,  the Parent will own all the capital  stock of
the Parent Subsidiary.  The Parent has no present plan or intention to cause the
Company to issue additional  shares of its stock that would result in the Parent
owning less than all the capital stock of the Company after the Merger.

          8. The Parent has no present plan or intention,  following the Merger,
to  liquidate  the  Company,   to  merge  the  Company  with  and  into  another
corporation, to sell or otherwise dispose of any of the stock of the Company, to
cause the Company to  distribute  to the Parent or any of its  subsidiaries  any
assets of the Company or the proceeds of any borrowings incurred by the Company,
or to cause the Company to sell or  otherwise  dispose of any of the assets held
by the Company at the time of the Merger, except for dispositions of such assets
in  the  ordinary  course  of  business  and  transfers   described  in  Section
368(a)(2)(C)  of the Internal  Revenue Code of 1986,  as amended (the "Code") or
Treasury Regulation Section 1.368-2(k).

          9.  Immediately  following  the Merger,  the Company  will hold (i) at
least 90% of the fair  market  value of the net  assets  and at least 70% of the
fair market value of the gross assets that were held by the Company  immediately
prior to the  Merger and (ii) at least 90% of the fair


<PAGE>

market  value of the net assets and at least 70% of the fair market value of the
gross assets that were held by the Parent  Subsidiary  immediately  prior to the
Merger. For purposes of this  representation,  amounts paid by the Company or by
the  Parent  Subsidiary  to  stockholders  who  receive  cash or other  property
(including cash in lieu of fractional shares of Parent Shares and cash paid with
respect to  Dissenting  Shares) in  connection  with the  Merger,  assets of the
Company  used  to pay  its  reorganization  expenses  and  all  redemptions  and
distributions  made by the Company  (other than  dividends  made in the ordinary
course of business)  immediately  preceding,  or in contemplation of, the Merger
will be included as assets held by the Company immediately prior to the Merger.

          10.  Except as otherwise  specifically  contemplated  under the Merger
Agreement, the Parent, the Parent Subsidiary, the Company and holders of Company
Shares will each pay their respective  expenses,  if any, incurred in connection
with the Merger. Except to the extent specifically contemplated under the Merger
Agreement  or the  Stockholder  Agreements,  neither  the  Parent nor the Parent
Subsidiary has paid, directly or indirectly, or has agreed to assume any expense
or other liability,  whether fixed or contingent,  incurred or to be incurred by
the Company or any holder of Company Shares in connection with or as part of the
Merger or any related transactions.

          11.  Following the Merger,  the Parent intends to cause the Company to
continue  its  "historic  business"  or to  use a  significant  portion  of  its
"historic  business assets" in a business (as such terms are defined in Treasury
Regulation Section 1.368-1(d)).

          12.  Neither  the Parent nor the Parent  Subsidiary  is an  investment
company as defined in Section 368(a)(2)(F)(iii) and (iv) of the Code.

          13.  Neither  the  Parent  nor the  Parent  Subsidiary  will  take any
position on any Federal,  state or local income or franchise tax return, or take
any other tax reporting position, that is inconsistent with the treatment of the
Merger as a  reorganization  within the  meaning of Section  368(a) of the Code,
unless otherwise required by a "determination" (as defined in Section 1313(a)(1)
of the  Code) or by  applicable  state or local  tax law (and  then  only to the
extent required by such applicable state or local tax law).

          14. None of the compensation received by any  stockholder-employee  of
the Company in respect of periods at or prior to the Effective  Time  represents
separate  consideration for any of its Company Shares. None of the Parent Shares
that will be received by any  stockholder-employee  of the Company in the Merger
represents  separately  bargained  for  consideration  which is allocable to any
employment   agreement   or   arrangement.   The   compensation   paid   to  any
stockholder-employees  will  be for  services  actually  rendered  and  will  be
determined by bargaining at arm's-length.

          15.  There is no  intercorporate  indebtedness  existing  between  the
Parent (or any of its  subsidiaries,  including the Parent  Subsidiary)  and the
Company (or any of its  subsidiaries)  that was issued or  acquired,  or will be
settled, at a discount.


<PAGE>

          16.  Neither  the  Parent  nor the  Parent  Subsidiary  is  under  the
jurisdiction  of a court in a Title 11 or similar  case  within  the  meaning of
Section 368(a)(3)(A) of the Code.

          17. In connection  with the Merger,  Company  Shares will be converted
solely into Parent Shares (except for cash paid in lieu of fractional  shares of
Parent Shares or cash paid with respect to Dissenting  Shares).  For purposes of
this representation,  Company Shares (including  Dissenting Shares) redeemed for
cash or other property furnished,  directly or indirectly, by the Parent will be
considered as exchanged for other than Parent Shares. Further, no liabilities of
the  Company  or any of the  holders of  Company  Shares  will be assumed by the
Parent,  nor will any of the Company Shares acquired by the Parent in connection
with the Merger be subject to any liabilities.

          18. Any  payments  with  respect to  Dissenting  Shares  shall be made
solely  by the  Company  or the  Surviving  Corporation,  and no cash  or  other
property  shall be  furnished,  directly  or  indirectly,  by the  Parent to the
Company,  the Surviving  Corporation or to any holder of Dissenting  Shares with
respect to any  Dissenting  Shares.  The total fair market  value of all Company
Nonvoting  Shares issued and outstanding as of the date of the Merger  Agreement
is equal to (i) less than 1% of the fair market value of the net assets and (ii)
less than 1% the fair  market  value of the gross  assets  that were held by the
Company immediately prior to the Merger.

          19. The Merger  Agreement,  the  Registration  Statement and the other
documents   described  in  the  Registration   Statement  represent  the  entire
understanding  of the  Parent  and the  Parent  Subsidiary  with  respect to the
Merger.

          20.  The  Parent  Subsidiary  is a  corporation  newly  formed for the
purpose  of  participating  in the Merger and at no time prior to the Merger has
had assets  (other than nominal  assets  contributed  upon the  formation of the
Parent Subsidiary,  which assets will be held by the Parent Subsidiary following
the Merger) or business operations.

          21. The Merger is being  undertaken  for  purposes  of  enhancing  the
business  of the Parent and for other good and valid  business  purposes  of the
Parent.

          22. The undersigned is authorized to make all the  representations set
forth herein on behalf of the Parent and the Parent Subsidiary.

          The  undersigned  acknowledges  that (i) the  opinion to be  delivered
pursuant to Section  [6(b)(vii)]  of the Merger  Agreement  will be based on the
accuracy  of the  representations  set forth  herein and on the  accuracy of the
representations  and  warranties  and  the  satisfaction  of the  covenants  and
obligations  contained in the Merger  Agreement and the various other  documents
related  thereto,  and (ii) such opinion will be subject to certain  limitations
and  qualifications  including  that  it may  not be  relied  upon  if any  such
representations  or  warranties  are not  accurate or if any such  covenants  or
obligations are not satisfied in all material respects.


<PAGE>

          The  undersigned  acknowledges  that such opinion will not address any
tax  consequences  of the Merger or any  action  taken in  connection  therewith
except as expressly set forth in such opinions.

                                          Very truly yours,

Agreement):

          1.  The  facts  relating  to the  contemplated  merger  of the  Parent
Subsidiary  with  and  into the  Company  (the  "Merger")  as  described  in the
Registration Statement and the documents described in the Registration Statement

state or local tax law (and then only to the extent  required by such applicable
state or local tax law).

          12. None of the compensation received by any  stockholder-employee  of
the Company in respect of periods at or prior to the Effective  Time  represents
separate  consideration for any of its Company Shares. None of the Parent Shares
that will be received by any  stockholder-employee  of the Company in the Merger
represents  separately  bargained  for  consideration  which is allocable to any
employment   agreement   or   arrangement.   The   compensation   paid   to  any
stockholder-employees  will  be for  services  actually  rendered  and  will  be
determined by bargaining at arm's-length.

          13.  There is no  intercorporate  indebtedness  existing  between  the
Parent (or any of its  subsidiaries,  including the Parent  Subsidiary)  and the
Company  (or any of its  subsidiaries)  that was  issued,  acquired,  or will be
settled, at a discount.

          14. The Company is not under the jurisdiction of a court in a Title 11
or similar case within the meaning of Section 368(a)(3)(A) of the Code.

          15. The Merger  Agreement,  the  Registration  Statement and the other
documents   described  in  the  Registration   Statement  represent  the  entire
understanding of the Company with respect to the Merger.


<PAGE>

          16. No assets of the Company have been sold,  transferred or otherwise
disposed  of which  would  prevent  the Parent  from  continuing  the  "historic
business" of the Company or from using a  significant  portion of the  "historic
business  assets" of the  Company in a  business  following  the Merger (as such
terms are defined in Treasury Regulation Section 1.368-1(d)).

          17. On the date of the Merger,  the fair market value of the assets of
the  Company  will  exceed  the  sum of its  liabilities,  plus  the  amount  of
liabilities, if any, to which such assets are subject.

          18. No holders of Voting Shares have  dissenter's  rights with respect
to the Merger under  applicable  law. Any  payments  with respect to  Dissenting
Shares shall be made solely by the Company or the Surviving Corporation,  and no
cash or other property shall be furnished,  directly or indirectly by the Parent
to the Company, the Surviving  Corporation or to any holder of Dissenting Shares
with respect to any Dissenting Shares.

          19. The total fair market value of all Company Nonvoting Shares issued
and outstanding as of the date of the Merger Agreement is equal to (i) less than
1% of the fair  market  value of the net  assets  and (ii) less than 1% the fair
market value of the gross assets that were held by the Company immediately prior
to the Merger.

          20. The undersigned is authorized to make all the  representations set
forth herein on behalf of the Company.

          The  undersigned  acknowledges  that (i) the  opinion to be  delivered
pursuant  to  Section  6(b)(vii)  of the Merger  Agreement  will be based on the
accuracy  of the  representations  set forth  herein and on the  accuracy of the
representations  and  warranties  and  the  satisfaction  of the  covenants  and
obligations  contained in the Merger  Agreement and the various other  documents
related  thereto,  and (ii) such opinion will be subject to certain  limitations
and  qualifications  including  that  it may  not be  relied  upon  if any  such
representations  or warranties  are not accurate or if any of such  covenants or
obligations are not satisfied in all material respects.

          The  undersigned  acknowledges  that such opinion will not address any
tax  consequences  of the Merger or any  action  taken in  connection  therewith
except as expressly set forth in such opinion.


                                Very truly yours,

                                DESTIA COMMUNICATIONS, INC.

the  matters  specified  in this  Agreement.  The  Stockholder  understands  and

including,  without limitation,  any voting agreement,  stockholder agreement or
voting trust. This Agreement has been duly executed and delivered by Stockholder
and constitutes a legal, valid and binding agreement of Stockholder, enforceable

advisers.

6. COVENANTS

     6.1 Except in accordance with the provisions of this Agreement, Stockholder
(and  the  Company,  pursuant  to  Section  6.8  hereof)  agrees,  prior  to the
termination of this Agreement as provided in Section 4 above,  not to,  directly
or indirectly:

          (a) sell, transfer,  pledge, encumber,  assign or otherwise dispose of
(including  by  merger,   testamentary  disposition,   interspousal  disposition
pursuant  to a domestic  relations  proceeding  or  otherwise  or  otherwise  by
operation of law), or enter into any contract,  option or other  arrangement  or
understanding  with  respect  to  the  sale,  transfer,   pledge,   encumbrance,
assignment or other disposition of, any of the Shares,  provided,  however, that
Stockholder may transfer Shares, with the prior written consent of Parent, which
shall  not  be  unreasonably  withheld,  to  a  trust  of  which  there  are  no
beneficiaries  other than the  parents,  spouse or children of  Stockholder,  or
otherwise make transfers for estate planning purposes,  so long as the trust and
the trustee(s),  or other  transferee,  thereof  deliver a written  agreement to
Parent,  reasonably  acceptable to Parent,  to be bound by the  restrictions set
forth in this Agreement,  and Parent  receives an opinion of counsel  reasonably
satisfactory  to it that this  Agreement  is  binding  upon  such  trust and the
trustee(s),  or other transferee,  thereof, as if such trust and trustee(s),  or
other  transferee,  were  Stockholder.  Any action  taken in  violation  of this
Section 6.1(a) shall be void and of no effect;

          (b) grant any proxies with  respect to any Shares,  deposit any Shares
into a voting trust or enter into a voting agreement with respect to any Shares;
or

          (c) take any action to solicit, initiate or encourage any inquiries or
proposals  that  constitute,  or could  reasonably  be  expected  to lead to, an
Acquisition  Proposal  (as  defined  in  the  Merger  Agreement)  or  engage  in
negotiations  or  discussions  with any  person or entity  (or group of  persons
and/or entities) other than Parent or its Affiliates concerning,  or provide any




                                     - 4 -
<PAGE>

non-public  information  to any  person or entity  relating,  to an  Acquisition
Proposal or otherwise  assist or facilitate  any effort or attempt by any person
or entity  (other than Parent and Parent  Subsidiary)  to make or  implement  an
Acquisition  Proposal.  Stockholder  will  immediately  cease and  terminate any
existing  solicitation,   initiation,  encouragement,  activity,  discussion  or
negotiation on his part with any parties  conducted  heretofore  with respect to
any proposed,  potential or contemplated  Acquisition Proposal,  and will notify
Parent promptly if he becomes aware of any  Acquisition  Proposal or any request
for  non-public  information in connection  with an Acquisition  Proposal or for
access to the  properties,  books or  records  of the  Company  by any person or
entity that informs the Company (or its  officers,  directors,  representatives,
agents,  Affiliates or associates) that it is considering  making or has made an
Acquisition Proposal.  Such notice shall be made orally and in writing and shall
indicate  the  identity  of the  offeror  and the terms and  conditions  of such
proposal,  inquiry or contact.  The foregoing provisions of this Section 6.1(c),
however,  shall not restrict Stockholder,  solely in his capacity as a member of
the  Company  Board (as  defined in the Merger  Agreement),  from voting to take
actions  permitted  under  Section 5(h) of the Merger  Agreement,  and shall not
restrict  Stockholder,  solely in his  capacity as an  executive  officer of the
Company,  from taking  actions  authorized  and directed by the Company Board so
long as such  actions  will not  cause  the  Company  to breach or result in the
Company being in breach of any provisions of the Merger Agreement.

     6.2 Stockholder agrees, during the term of this Agreement, to notify Parent
promptly of the number of any shares of Common  Stock  acquired  by  Stockholder
after the date hereof.

     6.3  Stockholder  agrees that  neither he nor any of his  Affiliates  will,
directly or indirectly,  unless in any such case specifically invited in writing
to do so by the board of  directors  of Parent,  for a period of two years after
the Effective Time, except as otherwise expressly set forth in this Agreement or
in the Merger  Agreement:  (i) individually or together with one or more persons
or entities,  acquire,  offer to acquire or agree to acquire,  or participate in
the financing of any acquisition of,  beneficial  ownership of any securities of
Parent  entitled  to vote in the  general  election  of  directors  (other  than
securities  distributed  generally to all holders of a class of securities,  and
restricted stock distributed to Stockholder pursuant to his employment agreement
with Parent), or securities  convertible into or exchangeable or exercisable for
such securities (other than stock options)  (collectively,  "SECURITIES");  (ii)
initiate,  propose,  engage or  otherwise  participate  in the  solicitation  of
stockholders or their proxies for approval of one or more stockholder  proposals
(including,  without limitation, the election of directors, any amendment to the
charter or bylaws,  or any  Business  Combination  Transaction)  with respect to
Parent;  (iii) otherwise act alone or in concert with any other person or entity
to seek to influence or control the management, board of directors,  policies or
affairs of Parent,  or to  solicit,  propose or  encourage  any other  person or
entity with respect to any form of Business Combination Transaction with Parent,
or to  solicit,  make or propose or  encourage  any other  person or entity with
respect to, or announce an intent to make,  any tender  offer or exchange  offer
for any  Securities;  (iv) request  Parent or its board of directors,  officers,
employees  or  agents,  to amend or  waive,  or seek any  modification  to,  any
provision of this  Section 6.3; or (v) take any action  designed to or which can
reasonably be expected to require Parent to make a public announcement regarding
any of the matters  referred to in this Section 6.3.  This Section 6.3 shall not
prohibit  any action by  Stockholder  solely in his  capacity  as a director  of
Parent, or solely in his capacity as an executive  officer of the Company,  from
taking  actions  authorized  and directed by the Parent Board (as defined in the
Merger Agreement). Notwithstanding the



                                     - 5 -
<PAGE>
provisions  of  Section  4, this  Section  6.3 shall  terminate  immediately  if
Stockholder  ceases to be a director  of the  Parent  Board  because  Parent has
breached its obligations under Section 6.7.

     6.4  Stockholder  agrees  that  for a  period  of one  year  following  the
Effective Time (the "LOCK-UP  PERIOD"),  Stockholder will not, without the prior
written consent of Parent,  directly or indirectly,  offer, offer to sell, sell,
contract  to sell,  grant any  option for the  purchase  of,  assign,  transfer,
pledge,  hypothecate or otherwise encumber or dispose of any beneficial interest
in  (including by merger,  testamentary  disposition,  interspousal  disposition
pursuant  to a domestic  relations  proceeding  or  otherwise  or  otherwise  by
operation of law)  ("Transfer")  any Parent  common  stock,  par value $0.01 per
share  ("PARENT  COMMON  STOCK"),   or  any  securities   convertible   into  or
exchangeable  or exercisable  for any shares of Parent Common Stock or any other
rights to acquire shares of Parent Common Stock (either  pursuant to Rule 144 of
the  regulations  under the Securities Act of 1933, as amended (the  "SECURITIES
ACT"),  or  otherwise)  either  beneficially  owned  by  Stockholder  as of  the
Effective Time or acquired by Stockholder  during the Lock-up Period as a result
of the exercise of options.  Notwithstanding the foregoing,  the undersigned may
(i)  Transfer  shares  of  Parent  Common  Stock as a bona  fide  gift or gifts,
provided that Stockholder provides prior written notice of such gift or gifts to
Parent and the donee or donees  thereof  deliver a written  agreement to Parent,
reasonably  acceptable  to  Parent,  to be bound by the  restrictions  set forth
herein  as if such  donee or donees  were  Stockholders;  (ii) on one  occasion,
Transfer up to 225,000 shares of Parent Common Stock;  and (iii) Transfer shares
of Parent Common Stock,  with the prior written  consent of Parent,  which shall
not be  unreasonably  withheld,  to a trust of which there are no  beneficiaries
other than the parents,  spouse or children of  Stockholder,  or otherwise  make
transfers for estate planning purposes, so long as the trust and the trustee(s),
or other transferee,  thereof deliver a written agreement to Parent,  reasonably
acceptable  to  Parent,  to be  bound  by the  restrictions  set  forth  in this
Agreement,  and Parent receives an opinion of counsel reasonably satisfactory to
it that this Agreement is binding upon such trust and the  trustee(s),  or other
transferee,  thereof, as if such trust and trustee(s), or other transferee, were
Stockholder.  Any  Transfer of Parent  Common Stock in violation of this Section
6.4 shall be void and of no effect.

     6.5 Notwithstanding the provisions of Section 4, Sections 6.3 and 6.4 shall
terminate immediately upon any termination of Stockholder's employment agreement
with Parent by Stockholder for Good Reason or any  termination of  Stockholder's
employment  agreement by Parent  without Cause ("Good  Reason" and "Cause" shall
have the meanings set forth in such employment agreement).

     6.6 For purposes of clause (i) of the  definition of "Change of Control" in
the Company's 1999 Flexible Incentive Plan, Stockholder hereby designates Parent
and Parent  Subsidiary.  From the date hereof  through the  termination  of this
Agreement pursuant to Section 4, this designation shall be irrevocable.

     6.7 Parent agrees that  Stockholder  and a Stockholder  Nominee (as defined
below)  will  become  members  of the  Parent  Board as of the  Effective  Time.
Following  the time when  Stockholder  and  Stockholder  Nominee,  respectively,
become  members of the Parent Board,  and  continuing for so long as Stockholder
directly  owns at least 10% of the  outstanding  shares of Parent  Common Stock,
Parent  agrees to cause Parent  Board to nominate  Stockholder  and  Stockholder
Nominee,  respectively,  for  election  as members  of the Parent  Board at each
annual


                                     - 6 -
<PAGE>

meeting of  stockholders  of Parent at which such director is up for re-election
and to recommend to its  stockholders a vote in favor of, and to solicit proxies
from its  stockholders  voting in favor of,  the  election  of  Stockholder  and
Stockholder  Nominee as members of Parent  Board,  all in the same manner and to
the same extent,  and in accordance with the same  procedures  applicable to the
election of members of the Parent Board  generally.  If at any time  Stockholder
directly  owns less than 10% of the  outstanding  shares of Parent Common Stock,
but at least 5% of the  outstanding  shares of  Parent  Common  Stock,  Parent's
obligations set forth above in this Section 6.7 shall apply to Stockholder  (and
not  Stockholder  Nominee)  unless,  at the  first  such  time or within 30 days
thereafter,  Stockholder  gives written  notice to Parent that such  obligations
shall thereafter  apply to Stockholder  Nominee (and not  Stockholder).  As used
herein,  "STOCKHOLDER NOMINEE" shall mean such person designated by Stockholder,
who  qualifies  as an  independent  director  of  Parent  for  purposes  of Rule

specificity  the grounds for such  removal,  and a  reasonable  opportunity  for
Stockholder  to be heard  as to why  such  contemplated  removal  should  not be
approved).  Notwithstanding  the  foregoing,  Parent's  obligations  under  this
Section  6.7  as  to  Stockholder  Nominee  shall  immediately  cease  upon  the
occurrence of any of the following events:  (i) Stockholder  Nominee chooses not
to serve as a member of the Parent Board, (ii) the stockholders of Parent do not
re-elect  Stockholder  Nominee as a member of Parent Board at the annual meeting

Nominee stating with specificity the grounds for such removal,  and a reasonable
opportunity  for  Stockholder  Nominee  to be heard as to why such  contemplated
removal  should  not be  approved);  provided,  however,  Stockholder  shall  be
entitled to designate a replacement  Stockholder  Nominee so long as Stockholder
continues  to  directly  own at least  10% of the  outstanding  shares of Parent
Common Stock.

     6.8 The  Company  recognizes  and  agrees  to use  commercially  reasonable
efforts to enforce the  Transfer  restrictions  placed on the Shares  under this

     7.2 REQUESTED REGISTRATION.

          (a) Upon the written request (the  "REQUEST") of  Stockholder,  on two
occasions,  Parent shall  promptly  cause to be filed under the Securities Act a
registration statement on such form as selected by Stockholder (which form shall
be subject to the approval of Parent, which shall not be unreasonably  withheld)
of  all  or  such  portion  of  the  Registrable   Securities  so  requested  by
Stockholder,  and Parent  shall take  reasonable  actions to effect,  as soon as
practicable,  subject to the reasonable  cooperation of  Stockholder,  within 90
days after the Request is received from Stockholder,  the registration under the
Securities Act, of the Registrable Securities which Parent has been so requested
to register by Stockholder.

          (b) EXPENSES. Parent shall pay the Registration Expenses in connection
with any  registration  effected  pursuant to this  Section 7.2 and  Stockholder
shall pay the Selling  Expenses in  connection  with any  registration  effected
pursuant to this Section 7.2.



                                     - 8 -
<PAGE>

          (c) EFFECTIVE REGISTRATION STATEMENT.  Notwithstanding anything to the
contrary herein, a registration requested pursuant to this Section 7.2 shall not
be deemed to have been effected  unless a  registration  statement  with respect
thereto has become effective and remains effective,  without interruption by any
stop  order for a period of more than  five days  (whether  or not  contiguous),
until  the  earlier  of (i)  120  days  following  the  effective  date  of such
registration  or (ii) the date when Parent  Shares sought to be offered and sold
pursuant  thereto are in fact offered and sold in  accordance  with the terms of
such offering.  Notwithstanding the foregoing,  a registration statement used in
connection  with a  non-underwritten  offering  shall not be deemed to have been
effected if (i) except during a Delay Period (as defined in Section  7.6),  such
registration  statement is not amended or  supplemented  within 10 business days
after the date on which it becomes  necessary to amend or  supplement it or (ii)
during a Delay Period, Stockholder elects, within 10 days after the commencement
of  the  Delay  Period,   to  discontinue  his  resale   participation  in  such
registration statement.

          (d) PRIORITY OF RIGHTS.  Whenever  Parent shall effect a  registration
pursuant to Section 7.2(a), holders of securities of Parent who have "piggyback"
registration  rights may  include  all or a portion of such  securities  in such
registration statement;  provided, however, that if such registration relates to
an underwritten  offering,  and the managing  underwriter shall inform Parent by
letter of its belief that the number or type of securities  of Parent  requested
by holders of the securities of Parent other than  Stockholder to be included in
such registration would materially and adversely affect the underwritten  public
offering,  then Parent shall include in such registration,  to the extent of the
number and type of  securities  which  Parent is so advised  can be sold in such
Public  Offering,   first,  all  of  the  Registrable  Securities  specified  by
Stockholder  in the Request and second,  for each holder of Parent's  securities
other than Stockholder,  the fraction of each holder's securities proposed to be
registered  which is obtained by dividing  (i) the number of the  securities  of
Parent that such holder  proposes  to include in such  registration  by (ii) the
total number of securities  proposed to be included in such  registration by all
holders other than Stockholder.

          (e)  SELECTION  OF  UNDERWRITERS.  If  Stockholder  so  requests,  the
registration  contemplated by Section 7.2(a) shall be for an underwritten public
offering.  In connection with any such underwritten public offering,  (a) Parent
shall  promptly  select the  managing  underwriter  subject to the  approval  of
Stockholder  (which  approval  shall not be  unreasonably  withheld,  delayed or
conditioned by Stockholder),  and (b) if he so desires, Stockholder may promptly
select the  co-managing  underwriter  subject to the  approval of Parent  (which
approval shall not be unreasonably withheld, delayed or conditioned by Parent).

          (f) LIMITATIONS ON REGISTRATION.  Parent shall not be required to file
a  registration  statement  pursuant  to this  Section  7.2 which  would  become
effective  within  180  days  following  the  effective  date of a  registration
statement  (other than a registration  statement filed on Form S-4 or S-8 or any
successor  form  of  limited  purpose)  filed  by  Parent  with  the  Commission
pertaining  to any public  offering of common stock,  or securities  convertible
into  or  exchangeable  for  common  stock,  for the  account  of  Parent  or an
underwritten  offering  of  common  stock,  or  securities  convertible  into or
exchangeable  for common stock,  for another holder of securities of Parent.  In
addition,  if, in the good faith determination of Parent's board of directors, a
registration would adversely affect certain activities of Parent to the material
detriment of Parent, then Parent may at its option direct that such registration
be delayed for a



                                     - 9 -
<PAGE>

period  not in  excess  of 90 days in the  aggregate  from the date of  Parent's
receipt of the  Request or from the first date upon which  Parent is required to
effect the registration contemplated by Section 7.2, as applicable.

          (g)  REGISTRATION  PROCEDURES.   In  connection  with  a  registration
statement  prepared by Parent  pursuant to this  Section  7.2,  Parent (a) shall
furnish to Stockholder,  a reasonable period of time prior to the filing thereof
with the  Commission,  a copy of the  registration  statement and each amendment
thereto or each amendment or supplement to the prospectus included therein,  and
shall use its reasonable efforts to reflect in each such document, when so filed
with the Commission,  such comments as Stockholder  reasonably may propose;  and
(b) if at any time the  Commission  shall  issue any stop order  suspending  the
effectiveness of a registration statement, or any state securities commission or
other regulatory  authority shall issue an order suspending the qualification or
exemption from qualification of the sale of securities under state securities or
blue sky laws,  Parent shall use commercially  reasonable  efforts to obtain the
withdrawal or lifting of such order at the earliest possible time.

     7.3 PIGGYBACK REGISTRATION.

          (a) RIGHT TO  INCLUDE  REGISTRABLE  SECURITIES.  If Parent at any time
proposes  to  register  any  of  its  securities  under  the  Securities  Act by
registration  on Forms S-1, S-2, S-3 or any successor or similar form(s) (except
registrations  on such  forms  or  similar  forms  solely  for  registration  of
securities  in  connection  with  (i)  an  employee  benefit  plan  or  dividend
reinvestment plan or a merger or consolidation or (ii) debt securities which are
not convertible into Common Stock), whether or not for sale for its own account,
it shall each such time give written  notice to  Stockholder of its intention to
do so at least 20 days prior to the  anticipated  filing date of a  registration
statement  with  respect  to such  registration  with the  Commission.  Upon the
written request of Stockholder  made as promptly as practicable and in any event
within 10 days after the receipt of any such notice, which request shall specify
the Registrable  Securities  intended to be disposed of by  Stockholder,  Parent
shall use reasonable efforts to effect the registration under the Securities Act
of all Registrable  Securities which Parent has been so requested to register by
Stockholder;  provided, however, that at any time after giving written notice of
its intention to register any  securities and prior to the effective date of the
registration  statement filed in connection with such  registration,  Parent may
elect to delay or not proceed with such  registration  If Parent elects to delay
or not proceed  with such  registration,  it shall give  written  notice of such
determination  to Stockholder  and Parent shall be relieved of its obligation to
register any  Registrable  Securities in connection with such  registration.  If
such registration relates to an underwritten  offering, any right of Stockholder
to  participate  in such  registration  pursuant  to this  Section  7.3 shall be
conditioned  upon his  agreeing  to offer  and sell  Registrable  Securities  in
accordance with the plan of  distribution  applicable to the other Parent Common
Stock sought to be offered and sold in such registration.

          (b) EXPENSES. Parent shall pay the Registration Expenses in connection
with any  registration  effected  pursuant to this  Section 7.3 and  Stockholder
shall pay the Selling  Expenses in  connection  with any  registration  effected
pursuant to this Section 7.3.

          (c) SELECTION OF UNDERWRITERS AND FORM OF REGISTRATION  STATEMENT.  In
connection  with each public  offering  effected  pursuant to this  Section 7.3,
Parent (or, if the



                                     - 10 -
<PAGE>

proposed registration by Parent is pursuant to a contractual demand registration
right,  the persons or entities  who caused such  registration  statement  to be
filed)  shall  select  the  managing  underwriters,  if  any,  and  the  form of
registration statement to be used in connection with any such offering.

     (d)  PRIORITY  IN  PIGGYBACK  REGISTRATIONS.  Notwithstanding  anything  in
Section  7.3  above  to  the  contrary,  if  the  managing  underwriter  of  any
underwritten  public  offering  shall inform Parent by letter of its belief that
the number or type of  Registrable  Securities  requested to be included in such
registration  would materially and adversely  affect such public offering,  then
Parent  shall  promptly  notify  Stockholder  of  such  fact.  If  the  managing
underwriter  does not agree to include all (or such lesser amount as Stockholder
shall, in his discretion,  agree to) of the number of the Registrable Securities
initially  requested by  Stockholder to be included in such  registration,  then
Parent shall include in such registration,  to the extent of the number and type
which Parent is so advised can be sold in such Public  Offering,  (i) first, the
Parent securities proposed to be sold by Parent or, if the proposed registration
by Parent is pursuant to a contractual  demand  registration  right,  the Parent
Common Stock proposed to be sold by the party making the demand and (ii) second,
to  the  extent  additional  Parent  Shares  may be  included,  that  number  of
Registrable  Securities  equal to the  product  of (x) the total  number of such
additional Parent Shares to be included in such  registration  multiplied by (y)
the fraction whose numerator is the number of Registrable  Securities  sought to
be included in such  registration  by Stockholder  and whose  denominator is the
total number of Parent Shares sought to be included in such  registration by all
persons  or  entities   entitled  to  participate  in  such  registration  on  a
"piggyback" basis.

     (e) EFFECTIVE PERIOD.  Parent shall use commercially  reasonable efforts to
maintain  the  effectiveness  of any  registration  pursuant to this Section 7.3
until the earlier (i) 90 days following the effective date of such  registration
or (ii) the date when the  securities  sought to be  offered  and sold  pursuant
thereto  are in fact  offered  and sold in  accordance  with  the  terms of such
offering.

     7.4 REGISTRATION PROCEDURES.

          (a) In connection with the registration of any Registrable  Securities
under the  Securities Act as provided in Sections 7.2 or 7.3, and subject to the
provisions of this Section 7, Parent shall as promptly as practicable:

               (i)  prepare  and  file  with  the   Commission   the   requisite
registration statement to effect such registration and thereafter use reasonable
efforts to cause such registration  statement to become and remain effective for
the applicable effective period;

               (ii)  use  reasonable  efforts  to  prepare  and  file  with  the
Commission such amendments and  supplements to such  registration  statement and
the  prospectus  used in  connection  therewith as may be necessary to keep such
registration statement effective and to comply with provisions of the Securities
Act with respect to the  disposition of all  Registrable  Securities  covered by
such registration statement for the applicable effective period;



                                     - 11 -
<PAGE>

               (iii) furnish to Stockholder  such number of conformed  copies of
such  registration  statement and of each such amendment and supplement  thereto
(in each case including all  exhibits),  such number of copies of the prospectus
contained in such registration  statement (including each preliminary prospectus
and any summary  prospectus) and any other prospectus filed under Rule 424 under
the Securities Act, in conformity with the requirements of the Securities Act;

               (iv)  use   reasonable   efforts  to   register  or  qualify  all
Registrable  Securities covered by such registration  statement under such other
securities or blue sky laws of such States of the United States of America where
an exemption is not  available  and as  Stockholder  shall  reasonably  request;
provided,  however,  that Parent  shall not for any such  purpose be required to
qualify  generally to do business as a foreign  corporation in any  jurisdiction
wherein  it would not,  but for the  requirements  of this  paragraph  (iv),  be
obligated to be so qualified or to consent to general  service of process in any
such jurisdiction;

               (v) notify  Stockholder  when a  prospectus  relating  thereto is
required to be delivered under the Securities Act and, upon discovery that there
has  occurred  any event as a result of which the  prospectus  included  in such
registration  statement,  as then in effect,  includes an untrue  statement of a
material fact or omits to state any material fact required to be stated  therein
or necessary to make the statements therein not misleading,  in the light of the
circumstances  under which they were made, and at the request of Stockholder use
its  reasonable  efforts to promptly  prepare and  furnish to  Stockholder  such
number of copies of a supplement to or an amendment of such prospectus as may be
necessary so that,  as thereafter  delivered to the Parents of such  securities,
such prospectus shall not include an untrue statement of a material fact or omit
to state a material fact required to be stated  therein or necessary to make the
statements therein not misleading in the light of the circumstances  under which
they were made;

               (vi)  otherwise  use its  reasonable  efforts to comply  with all
applicable rules and regulations of the Commission;

               (vii)  provide and cause to be  maintained  a transfer  agent and
registrar for all Registrable  Securities covered by such registration statement
from and after a date not later  than the  effective  date of such  registration
statement;

               (viii) furnish to  Stockholder,  prior to the filing thereof with
the Commission,  a copy of the registration statement and each amendment thereto
or each amendment or supplement to the prospectus  included  therein,  and shall
use its reasonable efforts to reflect in each such document,  when so filed with
the Commission, such comments as Stockholder reasonably may propose;

               (ix) use reasonable  efforts to list all  Registrable  Securities
covered by such registration  statement on any national  securities  exchange or
over-the-counter  market,  if any, on which  Registrable  Securities of the same
class covered by such registration statement are then listed; and

               (x)  subject to  customary  confidentiality  obligations,  Parent
shall permit reasonable access to Stockholder and its counsel and other advisors
to  its  financial



                                     - 12 -
<PAGE>

statements  and its other  books and  records to permit  Stockholder  to perform
reasonable due diligence.

          Stockholder  agrees that upon receipt of any notice from Parent of the
happening of an event of the kind described in Section 7.4(v), Stockholder shall
forthwith discontinue its disposition of Registrable  Securities pursuant to the
registration   statement   relating  to  such   Registrable   Securities   until
Stockholder's  receipt of the copies of the  supplemented or amended  prospectus
contemplated  by Section  7.4(v).  Stockholder  agrees to promptly  provide such
information regarding himself and his Registrable  Securities as Parent may from
time to time  reasonably  require for  inclusion in any  registration  statement
under Section 7.2 or 7.3.

     7.5  UNDERWRITTEN  OFFERINGS.  If  requested  by the  underwriters  for any
underwritten public offering by Stockholder pursuant to a registration requested
under Section 7.2, Parent shall enter into an  underwriting  agreement with such
underwriters  for  such  public  offering,   such  agreement  to  be  reasonably
satisfactory in substance and form to Parent,  Stockholder and the underwriters,
and to contain such representations and warranties by Parent and Stockholder and
such  other  terms as are  generally  prevailing  in  agreements  of that  type,
including, without limitation, customary indemnities and contribution provisions
generally  prevailing in agreements of that type.  Stockholder  shall  cooperate
with Parent in the  negotiation  of the  underwriting  agreement  and shall give
consideration  to the reasonable  suggestions  of Parent  regarding the form and
substance thereof. Stockholder shall be a party to such underwriting agreement.

     7.6 DELAY PERIODS. If at any time after the effectiveness of a registration
statement  under  Section 7.2 or 7.3 but prior to the  expiration of the related
effectiveness  period,  counsel to Parent (which counsel shall be experienced in
securities  laws  matters)  determines  in good faith that it is  reasonable  to
conclude  that the  compliance  by Parent  with its  disclosure  obligations  in
connection  with such  registration  statement  may  require the  disclosure  of
information  which the Board of Directors of Parent has  identified  as material
and which the Board of  Directors  has  determined  that  Parent has a bona fide
business  purpose for  preserving  as  confidential,  then  Parent  shall not be
required to  maintain  the  effectiveness  thereof or amend or  supplement  such
registration  statement for a period (a "DELAY PERIOD")  expiring three business
days  after  the  earlier  to  occur  of (A) the  date on  which  such  material
information  is  disclosed  to the public or ceases to be  material or Parent is
able to so comply with its disclosure obligations and Commission requirements or
(B) 90 days after Parent notifies  Stockholder of such good faith determination.
The effectiveness  period of such registration  statement will be extended for a
period  equal  to  the  duration  of  such  Delay  Period.  Parent  will  notify
Stockholder  of such  Delay  Period  as soon as  practicable  after the Board of
Directors makes such  determination.  Such notice shall state to the extent,  if
any,  as is  practicable,  an estimate  of the  duration  of such Delay  Period.
Stockholder  agrees that (x) upon  receipt of such  notice of a Delay  Period he
will  forthwith   discontinue   disposition  of  securities   pursuant  to  such
registration statement and (y) will not deliver any prospectus forming a part of
the registration statement in connection with any sale of Registrable Securities
until the expiration of such Delay Period.

     7.7 HOLDBACK  AGREEMENTS.  Stockholder agrees that, upon the request of and
only to the  extent  required  of other  executive  officers  of  Parent  by the
underwriter(s)  managing  any  registration  of Parent  Common  Stock  under the
Securities Act by Parent (except to the extent Stockholder is participating as a
selling  securityholder  pursuant to this  Agreement),  he will not,



                                     - 13 -
<PAGE>

without the prior written consent of such underwriters,  during the 7-day period
prior to, and during the 90-day period  beginning on, the effective date of such
registration,  sell,  make any short sale of,  pledge,  grant any option for the
purchase of or otherwise  dispose of, or enter into any other hedging or similar
transaction  with respect to, any Parent Shares,  or any securities  convertible
into or exchangeable for Parent Shares.

     7.8 INDEMNIFICATION AND CONTRIBUTION.

          (a) INDEMNIFICATION BY PARENT. In the event of any registration of any
securities of Parent under the Securities Act in which  Stockholder is a selling
stockholder,  Parent shall, and hereby does, indemnify and hold harmless, in the
case of any registration statement filed pursuant to this Section 7, Stockholder
and his agents and Affiliates  and, to the extent  required by any  underwriting
agreement  entered into by Parent,  each other person or entity who participates
as an underwriter in the registration  statement and each other person or entity
who  controls any such  underwriter  within the meaning of the  Securities  Act,
against  any and all  losses,  claims,  damages or  liabilities  insofar as such
losses,  claims,  damages or liabilities (whether arising in connection with any
actions or proceedings,  whether  commenced or threatened,  in respect  thereof)
arise out of or are based upon any untrue  statement or alleged untrue statement
of any fact contained in any registration  statement under which such securities
were  registered  under the Securities Act, any  preliminary  prospectus,  final
prospectus  or  summary  prospectus  contained  therein,  or  any  amendment  or
supplement  thereto, or any omission or alleged omission to state therein a fact
required to be stated  therein or  necessary to make the  statements  therein in
light of the circumstances under which they were made not misleading, and Parent
shall reimburse  Stockholder and each such agent or Affiliate and, to the extent
required by an underwriting  agreement  entered into by Parent,  any underwriter
and controlling person for any legal or any other expenses  reasonably  incurred
by them in connection  with  investigating  or defending  any such loss,  claim,
liability,  action or proceeding  described in this clause (a);  provided  that,
Parent  shall be required to reimburse  fees and  expenses  with respect to more
than one firm of  attorneys  (in  addition to any local  counsel) for all of the
indemnified parties only to the extent that any of the indemnified parties shall
have  differing  interests  from any other  indemnified  party;  and,  provided,
further,  that Parent  shall not be liable in any such case to the extent  that:
(i) any such  loss,  claim,  damage or  liability  (or action or  proceeding  in
respect  thereof) or expense arises out of or is based upon an untrue  statement
or  alleged  untrue  statement  or  omission  or alleged  omission  made in such
registration  statement,  any such preliminary  prospectus,  summary prospectus,
amendment  or  supplement  in  reliance  upon  and in  conformity  with  written
information  furnished  to Parent by or on  behalf of  Stockholder  specifically
stating that it is for  inclusion in such  registration  statement,  preliminary
prospectus, final prospectus, summary prospectus,  amendment or supplement, (ii)
with respect to any preliminary prospectus or prospectus (if such prospectus has
then been  amended or  supplemented)  to the extent  that any such loss,  claim,
damage, liability (or action or proceeding in respect thereof) or expense arises
out of or is based upon a sale of  Registrable  Securities to a person or entity
to whom there was not sent or given, at or prior to the written  confirmation of
such sale, a copy of the  prospectus  (or of the  prospectus  as then amended or
supplemented) if Parent has previously furnished copies thereof to Stockholder a
reasonable time in advance and the loss, claim, damage,  liability or expense of
Stockholder  results  from an untrue  statement or alleged  untrue  statement or
omission or alleged  omission of a material  fact  contained in the  preliminary
prospectus  (or the  prospectus)  which was corrected in the  prospectus (or the



                                     - 14 -
<PAGE>

prospectus  as amended or  supplemented),  or (iii) to the extent  that any such
loss,  claim,  damage,  liability or expense  arises out of or is based upon any
action  or  failure  to act by  Stockholder  that is found  in a final  judicial
determination  (or a settlement  tantamount  thereto) to  constitute  bad faith,
willful  misconduct  or  gross  negligence  on the  part  of  Stockholder.  Such
indemnity shall remain in full force and effect  regardless of any investigation
made by or on behalf of  Stockholder  or any such  director,  officer,  agent or
Affiliate  or  controlling  person  and  shall  survive  the  transfer  of  such
securities by Stockholder.

          (b) INDEMNIFICATION BY STOCKHOLDER.  If any Registrable Securities are
included in any  registration  statement,  Stockholder  shall indemnify and hold
harmless  (in the same  manner  and to the same  extent as set forth in  Section
7.8(a))  Parent,  each  director,  officer and employee,  agent and Affiliate of
Parent and, to the extent required by any underwriting agreement entered into by
Stockholder,  each other person or entity who  participates as an underwriter in
the  registration  statement or sale of such securities and each other person or
entity who controls any such  underwriter  within the meaning of the  Securities
Act,  with  respect to any  statement  or alleged  statement  in or  omission or
alleged omission from such registration  statement,  any preliminary prospectus,
final prospectus or summary prospectus  contained  therein,  or any amendment or
supplement  thereto,  if such  statement  or alleged  statement  or  omission or
alleged  omission  was made in  reliance  upon and in  conformity  with  written
information  furnished  to Parent by or on  behalf of  Stockholder  specifically
stating that it is for  inclusion in such  registration  statement,  preliminary
prospectus,  final  prospectus,  summary  prospectus,  amendment or  supplement;
provided,  however,  in no event shall the liability of  Stockholder  under this
Section  7.8(b)  exceed  the  proceeds  obtained  by the  sale of  Stockholder's
Registrable Securities in any such registration.

          (c) NOTICE OF CLAIMS,  ETC.  Promptly  after receipt by an indemnified
party of notice of the  commencement  of any action or  proceeding  involving  a
claim  referred to in the preceding  Sections  7.8(a) and (b), such  indemnified
party shall, if a claim in respect thereof is to be made against an indemnifying
party,  promptly give written notice to the latter of the  commencement  of such
action;  provided,  however,  that the failure of any indemnified  party to give
notice as  provided  herein  shall not  relieve  the  indemnifying  party of its
obligations  under the preceding  paragraphs of this Section 7.8,  except to the
extent  that  the  indemnifying  party  is  prejudiced  by  such  failure.   The
indemnified  party shall be entitled  to receive  the  indemnification  payments
described herein after providing such written notice to the indemnifying  party.
In  case  any  such  action  is  brought  against  an  indemnified   party,  the
indemnifying party shall be entitled to participate in and to assume the defense
thereof,  with counsel  reasonably  satisfactory to such indemnified  party, and
after  notice  from  the  indemnifying  party to such  indemnified  party of its
election so to assume the defense thereof,  the indemnifying  party shall not be
liable to such  indemnified  party for any legal or other expenses  subsequently
incurred by the latter in connection with the defense  thereof.  The indemnified
party  shall be  entitled  to  separate  counsel to the extent  contemplated  in
Sections  7.8(a)  and  7.8(b).   Each  indemnified   party  shall  furnish  such
information  regarding itself or the claim in question as an indemnifying  party
may  reasonably  request  in  writing  and as shall be  reasonably  required  in
connection with the defense of such claim and litigation resulting therefrom. No
indemnifying  party  shall  be  liable  for  any  settlement  of any  action  or
proceeding effected without its written consent, which shall not be unreasonably
withheld, delayed or conditioned,  unless such indemnifying party shall not have
satisfied its current  reimbursement  obligations hereunder within 30 days after
the initial written



                                     - 15 -
<PAGE>

request  by  the  indemnified  party  therefor.   Notwithstanding  the  previous
sentence,  the indemnifying  party shall not be liable for any settlement unless
the indemnifying  party receives an unconditional  release from all liability on
claims that are the subject matter of such action,  suit or proceeding.  Consent
of the  indemnified  party shall be required for the entry of any judgment or to
enter into a settlement  only when such judgment or settlement  does not include
as an unconditional term thereof the giving by the claimant or plaintiff to such
indemnified  party of a release  from all  liability in respect of such claim or
litigation or if such  judgment or settlement  includes an admission of fault by
the indemnified party.

          (d) CONTRIBUTION.  If the indemnification provided for in this Section
7.8 shall for any reason be held by a court to be  unavailable to an indemnified
party in  respect  of any loss,  claim,  damage or  liability,  or any action in
respect  thereof,  then,  in lieu of the amount paid or payable  under  Sections
7.8(a) and 7.8(b) hereof, the indemnified party and the indemnifying party shall
contribute to the aggregate losses,  claims,  damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating the
same) in such  proportion  as is  appropriate  to reflect the relative  fault of
Parent on one hand and  Stockholder  on the other  that  resulted  in such loss,
claim,  damage or liability,  or action in respect thereof, as well as any other
relevant equitable  considerations or, to the extent both Parent and Stockholder
sell  shares  pursuant to such  registration  statement,  and if the  allocation
provided above is not permitted by applicable  law, in such  proportion as shall
be appropriate to reflect the relative  benefits  received by Parent on one hand
and  Stockholder  on the  other.  No  person  or  entity  guilty  of  fraudulent
misrepresentation  (within the meaning of the Securities  Act) shall be entitled
to contribution  from any person or entity who was not guilty of such fraudulent
misrepresentation.  In  addition,  no  person or entity  shall be  obligated  to
contribute  hereunder any amounts in payment for any settlement of any action or
claim, effected without such person's or entity's written consent, which consent
shall not be unreasonably  withheld;  provided,  however,  in no event shall the
liability of any Stockholder  under this subsection exceed the proceeds obtained
by  the  sale  of  such  Stockholder's   Registrable   Securities  in  any  such
registration.

     7.9 LIMITATION. Nothing in this Section 7 shall be construed to confer upon
Stockholder  the right to sell Parent Common Stock in an amount  exceeding  that
allowed by Section 6.4 of this Agreement.

8. SURVIVAL OF  REPRESENTATIONS  AND  WARRANTIES.  Except as expressly  provided
otherwise,  all  representations,  warranties,  covenants and agreements made by
Stockholder  or Parent in this Agreement  shall survive the  termination of this
Agreement as set forth in Section 4 and any investigation at any time made by or
on behalf of any party.

9. NOTICES. All notices or other communications  required or permitted hereunder
shall be in writing (except as otherwise  provided herein),  given in the manner
provided in the Merger Agreement,  and shall be deemed duly given when received,
addressed as follows:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "ACT"),  OR THE SECURITIES  LAWS OF ANY  JURISDICTION.  SUCH
          SECURITIES MAY NOT BE OFFERED, SOLD,  TRANSFERRED,  PLEDGED,
          ASSIGNED, ENCUMBERED,  HYPOTHECATED OR OTHERWISE DISPOSED OF
          EXCEPT PURSUANT TO (I) A REGISTRATION STATEMENT WITH RESPECT
          TO SUCH  SECURITIES  THAT IS  EFFECTIVE  UNDER  SUCH  ACT OR
          APPLICABLE  STATE SECURITIES LAW, OR (II) ANY EXEMPTION FROM
          REGISTRATION  UNDER SUCH ACT, OR APPLICABLE STATE SECURITIES
          LAW,  RELATING TO THE  DISPOSITION OF SECURITIES,  INCLUDING
          RULE 144, PROVIDED AN OPINION OF COUNSEL IS FURNISHED TO THE
          COMPANY,  IN FORM AND SUBSTANCE  REASONABLY  SATISFACTORY TO
          THE  COMPANY,  TO THE  EFFECT  THAT AN  EXEMPTION  FROM  THE
          REGISTRATION REQUIREMENTS OF THE ACT AND/OR APPLICABLE STATE
          SECURITIES LAW IS AVAILABLE.

          IN ADDITION,  THE SECURITIES REPRESENTED BY THIS CERTIFICATE
          MAY NOT BE OFFERED, SOLD,  TRANSFERRED,  PLEDGED,  ASSIGNED,
          HYPOTHECATED  OR OTHERWISE  DISPOSED OF UNLESS SUCH TRANSFER
          COMPLIES  WITH THE  PROVISIONS  OF A  STOCKHOLDER  AGREEMENT
          DATED AS OF AUGUST 27, 1999 (THE "STOCKHOLDER AGREEMENT"), A
          COPY  OF  WHICH  IS ON



                                - 18 -
<PAGE>

          FILE AND MAY BE  INSPECTED  AT THE  PRINCIPAL  OFFICE OF THE
          COMPANY.  NO TRANSFER OF THE SECURITIES  WILL BE MADE ON THE
          BOOKS OF THE  COMPANY  UNLESS  ACCOMPANIED  BY  EVIDENCE  OF
          COMPLIANCE WITH THE TERMS OF SUCH STOCKHOLDER AGREEMENT. THE
          SECURITIES  REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT
          TO  OTHER  RIGHTS  AND  OBLIGATIONS  AS  SET  FORTH  IN  THE
          STOCKHOLDER AGREEMENT.

12.  ASSIGNS.  This Agreement  shall be binding upon and inure to the benefit of
the  parties  hereto  and their  respective  successors,  assigns  and  personal
representatives,  but neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto without the
prior written consent of the other parties.

13. GOVERNING LAW. EXCEPT AS EXPRESSLY SET FORTH BELOW,  THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE STATE OF DELAWARE,
REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER  APPLICABLE  PRINCIPLES
OF CONFLICTS OF LAWS THEREOF. IN ADDITION,  EACH OF STOCKHOLDER,  PARENT, PARENT
SUBSIDIARY  AND  COMPANY  HEREBY  AGREE  THAT ANY  DISPUTE  ARISING  OUT OF THIS
AGREEMENT SHALL BE HEARD IN THE APPROPRIATE COURT OF THE STATE OF NEW YORK OR IN
THE UNITED STATES  DISTRICT COURT FOR THE SOUTHERN  DISTRICT OF NEW YORK AND, IN
CONNECTION  THEREWITH,  EACH  PARTY TO THIS  AGREEMENT  HEREBY  CONSENTS  TO THE
JURISDICTION OF SUCH COURTS AND AGREES THAT ANY SERVICE OF PROCESS IN CONNECTION
WITH ANY DISPUTE  ARISING OUT OF THIS  AGREEMENT MAY BE GIVEN TO ANY OTHER PARTY
HERETO BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED,  AT THE RESPECTIVE ADDRESSES
SET FORTH IN SECTION 9 ABOVE.

14.  INJUNCTIVE  RELIEF.  The parties agree that in the event of a breach of any
provision  of this  Agreement,  the  aggrieved  party may be without an adequate
remedy at law. The parties  therefore agree that in the event of a breach of any
provision of this Agreement,  the aggrieved party shall be entitled to obtain in
any court of  competent  jurisdiction  a decree of  specific  performance  or to
enjoin  the  continuing  breach  of such  provision,  in each case  without  the
requirement that a bond be posted and without having to prove actual damages, as
well as to obtain damages for breach of this Agreement.  By seeking or obtaining
such relief, the aggrieved party will not be precluded from seeking or obtaining
any other relief to which it may be entitled.

15.  COUNTERPARTS;   FACSIMILE  SIGNATURES.  This  Agreement  may  be  executed,
including execution by facsimile,  in any number of counterparts,  each of which
shall be deemed to be an original and all of which together shall constitute one
and the same document.

16.  SEVERABILITY.  Any term or provision of this Agreement  which is invalid or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such invalidity or  unenforceability  without rendering invalid
or  unenforceable  the  remaining  terms and  provisions  of this  Agreement  or
affecting  the validity or  enforceability  of any of the terms or provisions of




                                     - 19 -
<PAGE>

this Agreement in any other jurisdiction.  If any provision of this Agreement is
so broad as to be unenforceable,  such provision shall be interpreted to be only
so broad as is enforceable.

17.  FURTHER  ASSURANCES.  Each party  hereto  shall  execute and  deliver  such
additional  documents  and take such  additional  actions as may be necessary or
desirable to consummate the transactions contemplated by this Agreement.

18. THIRD-PARTY BENEFICIARIES.  Nothing in this Agreement, expressed or implied,
shall be construed  to give any person or entity  other than the parties  hereto
any  legal or  equitable  right,  remedy  or claim  under or by  reason  of this
Agreement or any provision contained herein.

     WHEREAS,  as a  condition  to their  willingness  to enter  into the Merger

meeting  and shall  cause the  Shares  to be voted in any such  consent,  and in
either case,  shall:  (a) vote the Shares in favor of the adoption of the Merger
Agreement;  (b) vote the Shares against any action or agreement  that would,  or
could   reasonably  be  expected  to,  result  in  a  breach  of  any  covenant,

<PAGE>

that would, or could reasonably be expected to, impede,  interfere with,  delay,
postpone or attempt to discourage the Merger, including, but not limited to, (i)
any  extraordinary  corporate  transaction  (other than the  Merger),  such as a
merger,  other  business   combination,   recapitalization,   reorganization  or
liquidation,  involving Company (a "BUSINESS COMBINATION  TRANSACTION"),  (ii) a
sale or  transfer  of a  material  amount  of assets  of  Company  or any of its

management  or board of directors of Company,  except as otherwise  agreed to in
writing by Parent, (iv) any material change in the present capitalization of the
Company or (v) any other material change in the corporate  structure or business
of Company; and (d) without limiting the foregoing, consult with Parent prior to
any such meeting or consent and, in either case, vote such Shares in such manner
as is  determined  by Parent to be in  compliance  with the  provisions  of this
Section 1. Stockholder  acknowledges  receipt and review of a copy of the Merger
Agreement.  In furtherance  of this Section 1,  Stockholder  hereby  irrevocably
grants to, and appoints, Parent, and any individual designated in writing by it,
and each of them  individually,  as its proxy and  attorney-in-fact  (with  full
power of substitution), for and in its name, place and stead, to vote the Shares
at any meeting of the  stockholders of the Company called with respect to any of
the  matters  specified  in this  Agreement.  The  Stockholder  understands  and
acknowledges  that Parent is entering into the Merger Agreement in reliance upon
Stockholder's  execution and delivery of this Agreement.  The Stockholder hereby
affirms  that the  irrevocable  proxy  set  forth in this  Section 1 is given in
connection with the execution of the Merger Agreement, and that such irrevocable
proxy is given to secure the performance of the duties of Stockholder under this
Agreement.  Except as  otherwise  provided  for herein,  Stockholder  hereby (i)
affirms that the irrevocable  proxy is coupled with an interest and may under no
circumstances  be  revoked,  (ii)  ratifies  and  confirms  all that the proxies
appointed  hereunder  may  lawfully do or cause to be done by virtue  hereof and
(iii)  affirms  that such  irrevocable  proxy is  executed  and  intended  to be
irrevocable in accordance  with the provisions of Section 212(e) of the Delaware
General  Corporation Law (as defined in the Merger  Agreement).  Notwithstanding
any other provision of this Agreement,  the irrevocable  proxy granted hereunder
shall automatically terminate upon the termination of this Agreement pursuant to
Section 4.

2.  REPRESENTATIONS  AND  WARRANTIES OF  STOCKHOLDER.  Steven West, SS Econ Ltd.
Partnership  and SS Econ Ltd.  Partnership No. 2 represent and warrant to Parent
and Parent  Subsidiary with respect to that part of the Existing Shares owned by

    6.1  Except in accordance with the provisions of this Agreement, Stockholder

termination of this Agreement as provided in Section 4 above,  not to,  directly
or indirectly:

          (a) sell, transfer,  pledge, encumber,  assign or otherwise dispose of

pursuant  to a domestic  relations  proceeding  or  otherwise  or  otherwise  by
operation of law), or enter into any contract,  option or other  arrangement  or
understanding  with  respect  to  the  sale,  transfer,   pledge,   encumbrance,
assignment or other disposition of, any of the Shares,  provided,  however, that
Stockholder may transfer Shares, with the prior written consent of Parent, which
shall  not  be  unreasonably  withheld,  to  a  trust  of  which  there  are  no
beneficiaries  other than the  parents,  spouse or children of  Stockholder,  or
otherwise make transfers for estate planning purposes,  so long as the trust and
the trustee(s),  or other  transferee,  thereof  deliver a written  agreement to
Parent,  reasonably  acceptable to Parent,  to be bound by the  restrictions set
forth in this Agreement,  and Parent  receives an opinion of counsel  reasonably
satisfactory  to it that this  Agreement  is  binding  upon  such  trust and the
trustee(s),  or other transferee,  thereof, as if such trust and trustee(s),  or
other  transferee,  were  Stockholder.  Any action  taken in  violation  of this
Section 6.1(a) shall be void and of no effect;

          (b) grant any proxies with  respect to any Shares,  deposit any Shares
into a voting trust or enter into a voting agreement with respect to any Shares;

Acquisition  Proposal  (as  defined  in  the  Merger  Agreement)  or  engage  in
negotiations  or  discussions  with any  person or entity  (or group of  persons
and/or entities) other than Parent or its Affiliates concerning,  or provide any


                                       4
<PAGE>

non-public  information  to any  person or entity  relating,  to an  Acquisition
Proposal or otherwise  assist or facilitate  any effort or attempt by any person
or entity  (other than Parent and Parent  Subsidiary)  to make or  implement  an
Acquisition  Proposal.  Stockholder  will  immediately  cease and  terminate any
existing  solicitation,   initiation,  encouragement,  activity,  discussion  or
negotiation on his part with any parties  conducted  heretofore  with respect to
any proposed,  potential or contemplated  Acquisition Proposal,  and will notify
Parent promptly if he becomes aware of any  Acquisition  Proposal or any request
for  non-public  information in connection  with an Acquisition  Proposal or for
access to the  properties,  books or  records  of the  Company  by any person or
entity that informs the Company (or its  officers,  directors,  representatives,
agents,  Affiliates or associates) that it is considering  making or has made an
Acquisition Proposal.  Such notice shall be made orally and in writing and shall
indicate  the  identity  of the  offeror  and the terms and  conditions  of such
proposal, inquiry or contact.

     6.2 Stockholder agrees, during the term of this Agreement, to notify Parent
promptly of the number of any shares of Common  Stock  acquired  by  Stockholder
after the date hereof.

     6.3 [INTENTIONALLY OMITTED]

written consent of Parent,  directly or indirectly,  offer, offer to sell, sell,
contract  to sell,  grant any  option for the  purchase  of,  assign,  transfer,
pledge,  hypothecate or otherwise encumber or dispose of any beneficial interest
in  (including by merger,  testamentary  disposition,  interspousal  disposition
pursuant  to a domestic  relations  proceeding  or  otherwise  or  otherwise  by
operation of law)  ("Transfer")  any Parent  common  stock,  par value $0.01 per
share  ("PARENT  COMMON  STOCK"),   or  any  securities   convertible   into  or
exchangeable  or exercisable  for any shares of Parent Common Stock or any other
rights to acquire shares of Parent Common Stock (either  pursuant to Rule 144 of
the  regulations  under the Securities Act of 1933, as amended (the  "SECURITIES
ACT"),  or  otherwise)  either  beneficially  owned  by  Stockholder  as of  the
Effective Time or acquired by Stockholder  during the Lock-up Period as a result
of the exercise of options.  Notwithstanding the foregoing,  the undersigned may
(i)  Transfer  shares  of  Parent  Common  Stock as a bona  fide  gift or gifts,
provided that Stockholder provides prior written notice of such gift or gifts to
Parent and the donee or donees  thereof  deliver a written  agreement to Parent,
reasonably  acceptable  to  Parent,  to be bound by the  restrictions  set forth
herein  as if such  donee or  donees  were  Stockholders;  (ii)  Transfer  up to
$5,000,000  worth of Parent Common Stock;  and (iii)  Transfer  shares of Parent
Common  Stock,  with the prior  written  consent of Parent,  which  shall not be

the parents, spouse or children of Stockholder,  or otherwise make transfers for
estate  planning  purposes,  so long as the trust and the  trustee(s),  or other
transferee, thereof deliver a written agreement to Parent, reasonably acceptable
to Parent,  to be bound by the  restrictions  set forth in this  Agreement,  and
Parent  receives an opinion of counsel  reasonably  satisfactory to it that this
Agreement is binding upon such trust and the  trustee(s),  or other  transferee,
thereof, as if such trust and trustee(s), or other transferee, were Stockholder.
Any  Transfer of Parent  Common  Stock in violation of this Section 6.4 shall be
void and of no effect.

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "ACT"),  OR THE SECURITIES  LAWS OF ANY  JURISDICTION.  SUCH

          APPLICABLE  STATE SECURITIES LAW, OR (II) ANY EXEMPTION FROM
          REGISTRATION



                                  7
<PAGE>

          UNDER SUCH ACT, OR APPLICABLE STATE SECURITIES LAW, RELATING
          TO  THE  DISPOSITION  OF  SECURITIES,  INCLUDING  RULE  144,
          PROVIDED AN OPINION OF COUNSEL IS  FURNISHED TO THE COMPANY,
          IN  FORM  AND  SUBSTANCE  REASONABLY   SATISFACTORY  TO  THE
          COMPANY,   TO  THE  EFFECT  THAT  AN   EXEMPTION   FROM  THE
          REGISTRATION REQUIREMENTS OF THE ACT AND/OR APPLICABLE STATE
          SECURITIES LAW IS AVAILABLE.

          IN ADDITION,  THE SECURITIES REPRESENTED BY THIS CERTIFICATE
          MAY NOT BE OFFERED, SOLD,  TRANSFERRED,  PLEDGED,  ASSIGNED,
          HYPOTHECATED  OR OTHERWISE  DISPOSED OF UNLESS SUCH TRANSFER
          COMPLIES  WITH THE  PROVISIONS  OF A  STOCKHOLDER  AGREEMENT
          DATED AS OF AUGUST 27, 1999 (THE "STOCKHOLDER AGREEMENT"), A
          COPY  OF  WHICH  IS ON  FILE  AND  MAY BE  INSPECTED  AT THE
          PRINCIPAL  OFFICE  OF  THE  COMPANY.   NO  TRANSFER  OF  THE
          SECURITIES  WILL BE MADE ON THE BOOKS OF THE COMPANY  UNLESS
          ACCOMPANIED BY EVIDENCE OF COMPLIANCE WITH THE TERMS OF SUCH
          STOCKHOLDER  AGREEMENT.  THE SECURITIES  REPRESENTED BY THIS
          CERTIFICATE ARE ALSO SUBJECT TO OTHER RIGHTS AND OBLIGATIONS
          AS SET FORTH IN THE STOCKHOLDER AGREEMENT.

12.  ASSIGNS.  This Agreement  shall be binding upon and inure to the benefit of
the  parties  hereto  and their  respective  successors,  assigns  and  personal
representatives,  but neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto without the
prior written consent of the other parties.

13. GOVERNING LAW. EXCEPT AS EXPRESSLY SET FORTH BELOW,  THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE STATE OF DELAWARE,
REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER  APPLICABLE  PRINCIPLES
OF CONFLICTS OF LAWS THEREOF. IN ADDITION,  EACH OF STOCKHOLDER,  PARENT, PARENT
SUBSIDIARY  AND  COMPANY  HEREBY  AGREE  THAT ANY  DISPUTE  ARISING  OUT OF THIS
AGREEMENT SHALL BE HEARD IN THE APPROPRIATE COURT OF THE STATE OF NEW YORK OR IN
THE UNITED STATES  DISTRICT COURT FOR THE SOUTHERN  DISTRICT OF NEW YORK AND, IN
CONNECTION  THEREWITH,  EACH  PARTY TO THIS  AGREEMENT  HEREBY  CONSENTS  TO THE
JURISDICTION OF SUCH COURTS AND AGREES THAT ANY SERVICE OF PROCESS IN CONNECTION
WITH ANY DISPUTE  ARISING OUT OF THIS  AGREEMENT MAY BE GIVEN TO ANY OTHER PARTY
HERETO BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED,  AT THE RESPECTIVE ADDRESSES
SET FORTH IN SECTION 9 ABOVE.

14.  INJUNCTIVE  RELIEF.  The parties agree that in the event of a breach of any
provision  of this  Agreement,  the  aggrieved  party may be without an adequate
remedy at law. The parties



                                       8
<PAGE>

therefore  agree  that  in the  event  of a  breach  of any  provision  of  this
Agreement,  the  aggrieved  party  shall be  entitled  to obtain in any court of
competent  jurisdiction  a decree  of  specific  performance  or to  enjoin  the
continuing breach of such provision, in each case without the requirement that a
bond be posted and without having to prove actual damages,  as well as to obtain
damages for breach of this Agreement.  By seeking or obtaining such relief,  the
aggrieved party will not be precluded from seeking or obtaining any other relief
to which it may be entitled.

15.  COUNTERPARTS;   FACSIMILE  SIGNATURES.  This  Agreement  may  be  executed,
including execution by facsimile,  in any number of counterparts,  each of which
shall be deemed to be an original and all of which together shall constitute one
and the same document.

16.  SEVERABILITY.  Any term or provision of this Agreement  which is invalid or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such invalidity or  unenforceability  without rendering invalid
or  unenforceable  the  remaining  terms and  provisions  of this  Agreement  or
affecting  the validity or  enforceability  of any of the terms or provisions of
this Agreement in any other jurisdiction.  If any provision of this Agreement is
so broad as to be unenforceable,  such provision shall be interpreted to be only
so broad as is enforceable.

17.  FURTHER  ASSURANCES.  Each party  hereto  shall  execute and  deliver  such
additional  documents  and take such  additional  actions as may be necessary or
desirable to consummate the transactions contemplated by this Agreement.

18. THIRD-PARTY BENEFICIARIES.  Nothing in this Agreement, expressed or implied,
shall be construed  to give any person or entity  other than the parties  hereto
any  legal or  equitable  right,  remedy  or claim  under or by  reason  of this
Agreement or any provision contained herein.

shall  not  be  unreasonably  withheld,  to  a  trust  of  which  there  are  no
beneficiaries  other than the  parents,  spouse or children of  Stockholder,  or
otherwise make transfers for estate planning purposes,  so long as the trust and
the trustee(s),  or other  transferee,  thereof  deliver a written  agreement to
Parent,  reasonably  acceptable to Parent,  to be bound by the  restrictions set

satisfactory  to it that this  Agreement  is  binding  upon  such  trust and the
trustee(s),  or other transferee,  thereof, as if such trust and trustee(s),  or

Proposal or otherwise  assist or facilitate  any effort or attempt by any person
or entity  (other than Parent and Parent  Subsidiary)  to make or  implement  an
Acquisition  Proposal.  Stockholder  will  immediately  cease and  terminate any
existing  solicitation,   initiation,  encouragement,  activity,  discussion  or
negotiation on his part with any parties  conducted  heretofore  with respect to
any proposed,  potential or contemplated  Acquisition Proposal,  and will notify
Parent promptly if he becomes aware of any  Acquisition  Proposal or any request
for  non-public  information in connection  with an Acquisition  Proposal or for
access to the  properties,  books or  records  of the  Company  by any person or
entity that informs the Company (or its  officers,  directors,  representatives,
agents,  Affiliates or associates) that it is considering  making or has made an
Acquisition Proposal.  Such notice shall be made orally and in writing and shall
indicate  the  identity  of the  offeror  and the terms and  conditions  of such
proposal, inquiry or contact.

the  regulations  under the Securities Act of 1933, as amended (the  "SECURITIES
ACT"),  or  otherwise)  either  beneficially  owned  by  Stockholder  as of  the

of the exercise of options.  Notwithstanding the foregoing,  the undersigned may
(i)  Transfer  shares  of  Parent  Common  Stock as a BONA  FIDE  gift or gifts,
provided that Stockholder provides prior written notice of such gift or gifts to

and the same document.

16.  SEVERABILITY.  Any term or provision of this Agreement  which is invalid or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective

affecting  the validity or  enforceability  of any of the terms or provisions of
this Agreement in any other jurisdiction.  If any provision of this Agreement is
so broad as to be unenforceable,  such provision shall be interpreted to be only
so broad as is enforceable.

consult  with Parent  prior to any such  meeting or consent and, in either case,
vote such Shares in such manner as is  determined  by Parent to be in compliance
with the  provisions  of this Section 1.  Stockholder  acknowledges  receipt and
review of a copy of the Merger  Agreement.  In  furtherance  of this  Section 1,
Stockholder  hereby  irrevocably  grants  to,  and  appoints,  Parent,  and  any

proxy and  attorney-in-fact  (with full power of  substitution),  for and in its
name,  place and stead, to vote the Shares at any meeting of the stockholders of
the  Company  called  with  respect  to any of the  matters  specified  in  this
Agreement.  The Stockholder understands and acknowledges that Parent is entering
into the Merger Agreement in reliance upon Stockholder's  execution and delivery
of this Agreement. The Stockholder hereby affirms that the irrevocable proxy set
forth in this Section 1 is given in connection  with the execution of the Merger
Agreement, and that such irrevocable proxy is given to secure the performance of
the duties of Stockholder under this Agreement. Except as otherwise provided for
herein,  Stockholder  hereby (i) affirms that the  irrevocable  proxy is coupled
with an interest and may under no  circumstances  be revoked,  (ii) ratifies and

shall  not  be  unreasonably  withheld,  to  a  trust  of  which  there  are  no
beneficiaries  other than the  parents,  spouse or children of  Stockholder,  or
otherwise make transfers for estate planning purposes,  so long as the trust and
the trustee(s),  or other  transferee,  thereof  deliver a written  agreement to
Parent,  reasonably  acceptable to Parent,  to be bound by the  restrictions set
forth in this Agreement,  and Parent  receives an opinion of counsel  reasonably
satisfactory  to it that this  Agreement  is  binding  upon  such  trust and the

immediately   cease  and  terminate  any  existing   solicitation,   initiation,
encouragement,  activity, discussion or negotiation on its part with any parties
conducted  heretofore  with respect to any proposed,  potential or  contemplated
Acquisition Proposal, and will notify Parent promptly if it becomes aware of any
Acquisition  Proposal or any request for  non-public  information  in connection
with an Acquisition  Proposal or for access to the properties,  books or records
of the  Company  by any  person or  entity  that  informs  the  Company  (or its
officers, directors, representatives,  agents, Affiliates or associates) that it
is considering making or has made an Acquisition Proposal.  Such notice shall be
made orally and in writing and shall  indicate  the  identity of the offeror and

terms of an all stock transaction  through which Viatel will purchase all of the

Furthermore,  the Boards of  Directors  of Viatel and  Destia  have  unanimously

stockholders.  The  combined  company  will  have  a  market  capitalization  of
approximately $2.0 billion and latest quarter annualized consolidated revenue of
approximately $576.0 million.

Under the terms of the proposed transaction, Viatel will exchange 0.445 share of
