Item 2.  Acquisition or Disposition of Assets

         On February 6, 1998, Global Telecommunication  Solutions, Inc. ("GTS"),
CCI Acquisition  Corp., a wholly owned subsidiary of GTS ("Acquisition  Corp."),
Centerpiece   Communications,   Inc.   ("CCI")  and  J.  Mark   Rubenstein  (the
"Stockholder")   executed  a  Merger  and   Reorganization   Agreement  ("Merger
Agreement"),  pursuant  to  which  CCI  was  merged  ("Merger")  with  and  into
Acquisition Corp.

         The parties closed the Merger on February 6, 1998 ("Closing  Date") and
all related  transactions  were  consummated  as  contemplated  on that date. On
February 6, 1998, a Certificate  of Merger was filed with the Secretary of State
of the State of New Jersey.

         In  connection  with the  Merger,  GTS issued an  aggregate  of 401,284
shares of GTS's common Stock ("GTS  Shares") to the  Stockholder,  determined by
dividing  $2,500,000 by the average  closing sales price of one GTS Share on the
20  consecutive  trading  days  ending  two  days  prior  to the  Closing  Date.
Furthermore,  the  Stockholder  entered into an agreement  with Sheldon  Finkel,
Chairman of the Board of GTS,  pursuant to which the Stockholder was granted tag
along  rights to sell his shares of common  stock in the event Mr.  Finkel sells
shares  of  common  stock  of GTS  owned  by him  under  certain  circumstances.
Additionally,  GTS  delivered  a  promissory  note  to  the  Stockholder  in the
aggregate principal amount of $1 million,  which is secured by substantially all
the assets of CCI.

         On  the  Closing  Date,  GTS  entered  into  an  employment   agreement
("Employment Agreement") with J. Mark Rubenstein,  the President of CCI, who was
appointed the Vice President - Wholesale Sales of GTS. The Employment  Agreement
is for a term through December 2001. Mr. Rubenstein is to receive an annual base
salary of  $150,000,  subject to annual  increases  and  bonuses as the Board of
Directors of GTS may, in its discretion, determine. GTS also agreed to cause the
stockholder to be elected to the Board of Directors of The Acquisition Corp. for
so long as the Stockholder is employed by GTS or any of its affiliates.

         Pursuant  to the Merger  Agreement,  GTS agreed to file a  registration
statement  with the SEC to  register  the GTS Shares  issued to  Stockholder  in
connection with the Merger on or before November 1, 1998, or to include all such
shares  in a  registration  statement  which  has been  filed  but not  declared
effective  if  allowable  under the  Securities  Act and the  rules  promulgated
thereunder,  so that  they  may be sold by the  Stockholder.  Additionally,  GTS
agreed  to use its best  efforts  to cause  such  registration  statement  to be
declared  effective  by the SEC no later  than  January  31,  1999 and once such
registration  statement is declared  effective,  to keep it effective  until all
securities  registered  thereby are either sold or can be sold under Rule 144(k)
of  the  rules  promulgated  under  the  Securities  Act.   Notwithstanding  the
foregoing,  the stockholder  executed a "lock-up"  agreement (i) prohibiting his
sale of such  shares  for a period of one year after the  Closing  Date and (ii)
limiting  the number of such shares  which he may sell in any  calendar  quarter
during the second year thereafter to 25% of the GTS Shares; provided,


                                        2



<PAGE>



however,  in the event the Stockholder fails to sell the complete 25% during any
calendar  quarter the  Stockholder  shall be  entitled to sell,  during the next
calendar  quarter,  the  lesser  of the  following  percentage  of the GTS Stock
acquired by him hereunder: (1) the sum of (A) 25% and (B) the difference between
25% and that percentage sold during the immediately  preceding calendar quarter;
and (2) 40%.

                    CONVERSION OF SHARES AND RELATED MATTERS

     Section 2.1  Conversion of Outstanding  Stock of the Merger  Subsidiary and
Exchange for Stock of Surviving  Corporation.  Upon  consummation of the Merger,
all 100  shares of the common  stock,  no par  value,  of the Merger  Subsidiary
("Merger Subsidiary Stock") outstanding  immediately prior to the Effective Time
shall,  by virtue of the Merger and without any action on the part of the holder
thereof, be converted into and exchanged for 100 shares of the common stock, par

Surviving  Corporation  immediately  after the  Effective  Time.  All  shares of
Surviving  Corporation  Stock shall be fully paid and  non-assessable.  Promptly
after the Effective Time, the Surviving  Corporation  shall issue to GTS a stock
certificate  representing  the 100  shares  of  Surviving  Corporation  Stock in
exchange for the  certificate or  certificates  which formerly  represented  100
shares of Merger Subsidiary Stock, which stock certificates shall be immediately
canceled.

     Section 2.2 Conversion of CCI Shares.  As of the Effective Time, all of the
outstanding  shares of common stock,  par value $.01 per share,  of CCI that are
outstanding  immediately prior to the Effective Time (the "CCI Shares") shall be

to $5,000,000 (the "Merger Consideration"), comprised of the following:


$1,500,000 in immediately available funds ( the "Cash Consideration");
a number of shares ("Stock  Consideration")  of GTS common stock, par value $.01
per share ("GTS Stock"),  determined by dividing $2,500,000 by the lesser of (a)
average  of the  closing  sales  price of one share of GTS  Stock on the  twenty
trading days ending two days immediately  prior to the Closing Date; and (b) the
stock price used to  calculate  equity  consideration  paid to any other  entity
involved in a merger, asset acquisition, or like transaction with GTS during the
sixty (60) day  period  immediately  prior to the  Closing  Date (the  number of
shares  of  GTS  Stock  constituting  the  Stock  Consideration  payable  to the
Stockholder  shall be rounded up or down to the nearest whole number of shares).
The Common Stock,  upon issuance,  shall be subject to the  restrictions of Rule
144  promulgated  by the  United  States  of  America  Securities  and  Exchange
Commission  (the  "SEC")  under the  Securities  Act of 1933,  as  amended  (the
"Securities  Act"),  until properly disposed of in accordance with the terms and
conditions  of Rule 144 or any other  provision of the federal  securities  laws
authorizing disposal of such stock.

a secured non-negotiable  promissory note substantially in the form of Exhibit D
attached to this Agreement (the "Promissory  Note"),  in the principal amount of
One Million Dollars ($1,000,000.00),  which shall accrue interest at the rate of
eight  percent (8%) per annum,  payable as follows:  payments of Two Hundred and
Fifty Thousand Dollars ($250,000),  plus interest accrued on the Promissory Note
up to the payment  date,  shall be made on October 31, 1998 and January 1, 1999;
and  payments  of One Hundred  Twenty Five  Thousand  Dollars  ($125,000),  plus
interest accrued on the Promissory Note up to the payment date, shall be made on
March 31, 1999, June 30, 1999,  September 30, 1999 and January 1, 2000.  Amounts
payable under the Promissory Note will be secured by a Security Agreement in the
form  attached  hereto  as  Exhibit E  delivered  by  Merger  Subsidiary  to the
Stockholder  concurrently  with the execution of this  Agreement  (the "Security
Agreement").  Should GTS or Merger Subsidiary raise additional funds,  either in
the form of debt or equity,  following  the  Closing  Date,  in  addition to the
scheduled  principal  and  interest  payments set forth  herein,  it shall use a
portion  of such  funds to pay  down  the  balance  due on the  Promissory  Note
according to the following formula:  One Hundred Thousand Dollars (or lesser sum
as shall then be outstanding) for each One Million Dollars  ($1,000,000) raised.
Such  additional  payments shall be paid to Stockholder  within Thirty (30) days
after the closing on each amount raised.

     Section 2.3  Balance  Sheet  Adjustment.  The Cash  Consideration  shall be
adjusted (the "Balance Sheet Adjustment") to reflect X in the following formula:

X = Y - Z, where

X = the dollar amount of the increase or decrease in the Cash Consideration;
Y = The total cash and the net realizable value of CCI's accounts  receivable as
of the Closing  Date;  and Z = the total of all of CCI's  liabilities  as of the
Closing Date, except those liabilities set forth on Schedule 2.3.

The  Stockholder or its designee shall deliver to GTS a balance sheet and income
statement  ( which  shall  be in the  form of a  compilation),  dated  as of the
Closing  Date,  no later than  fourteen  (14) days after the Closing  Date.  The
Balance  Sheet  Adjustment  shall be  determined  on or before 90 days after the
Closing Date.  GTS and the  Stockholder  will cooperate in good faith to prepare
the Balance Sheet Adjustment.  If any dispute arises over the preparation of the
Balance Sheet  Adjustment  which cannot be reconciled by the Stockholder and GTS
in good  faith,  the  Stockholder  and GTS  will  engage a  mutually  acceptable
independent  public  accounting firm to determine the Balance Sheet  Adjustment,
such  accounting  fees to be paid by the  parties  equally.  The  Balance  Sheet
Adjustment  determined  by  that  accounting  firm  will  be  binding  upon  the
Stockholder and GTS.

     Section 2.4 Additional Payments. If the Balance Sheet Adjustment results in
the  obligation  of either party to the other,  such amount shall be paid within
ten (10) days after final determination of the Balance Sheet Adjustment.

         Section 2.5  Registration Rights.

                  (a) General.  No later than November 1, 1998, GTS shall file a
registration statement with the SEC to register the shares issued to Stockholder
hereunder  for  resale,  or shall  include  all such  shares  in a  registration
statement which has been filed but not declared effective if allowable under the
Securities Act and the rules promulgated thereunder, so that they may be sold by
the Stockholder to the public except as otherwise  provided  herein  (including,
without limitation,  Exhibit F hereto).  GTS shall use its best efforts to cause
such  registration  statement to be declared  effective by the SEC no later than
January 31, 1999 and once such registration statement is declared effective,  to
keep it effective until all securities registered thereby are either sold or can
be sold under the exemption from the registration requirements of the Securities
Act  contained  in Rule  144(k)  thereof.  GTS shall bear all fees and  expenses
incurred  by  it  in  connection   with  the  preparation  and  filing  of  such
registration  statement.  The Stockholder  will pay all brokerage  discounts and
commissions with respect to the sale of his GTS Shares and any fees and expenses
of separate  counsel and accountants  which may be retained by the  Stockholder.
The  Stockholder  will be  required to execute a lock-up  agreement  in the form
annexed hereto as Exhibit F pursuant to which he shall agree (i) not to sell any
GTS Shares until the one-year  anniversary  of the Closing Date and (ii) only to
sell up to 25% of the GTS Share  acquired by him in  connection  with the Merger
during any three-month period during the one-year period  thereafter;  provided,
however,  in the event the Stockholder fails to sell the complete 25% during any
calendar  quarter the  Stockholder  shall be  entitled to sell,  during the next
calendar  quarter,  the  lesser  of the  following  percentage  of the GTS Stock
acquired by him hereunder: (1) the sum of (A) 25% and (B) the difference between
25% and that percentage sold during the immediately  preceding calendar quarter;
and (2) 40%.


<PAGE>

         Notwithstanding any other provision of this Section 2.5, GTS shall have
no obligation  hereunder to register the GTS Shares on behalf of the Stockholder
unless (1) the  Stockholder  executes a lock-up  agreement  in the form  annexed
hereto as Exhibit F and (2) the  Stockholder  provides  to GTS  information  and
documents  with respect to his  ownership of the GTS Shares and other matters as
GTS shall reasonably request for disclosure in the registration statement.

         (b) Indemnification.

     (i) GTS shall indemnify and hold harmless,  to the extent permitted by law,
the Stockholder against all losses,  claims,  damages,  liabilities and expenses
(including  reasonable attorneys' fees, costs and expenses) caused by any untrue
or alleged  untrue  statement of material  fact  contained  in any  registration
statement  filed  pursuant  to  Section  2.5  (a),   prospectus  or  preliminary
prospectus or any amendment  thereof or supplement  thereto,  or any omission or
alleged  omission of material fact required to be stated therein or necessary to
make the  statements  therein  not  misleading,  except  insofar as the same are
caused by or contained in or omitted  from  information  furnished in writing to
GTS by the Stockholder for use therein.

     (ii) In connection with any registration statement in which the Stockholder
participates,  the  Stockholder  will  furnish  to GTS such  information  as GTS
reasonably  requests for use in connection with any such registration  statement
or  prospectus  and, to the extent  permitted by law,  will  indemnify  GTS, its
directors  and  officers and each Person who controls GTS (within the meaning of
Section 15 of the Securities Act of 1933, as amended (the  "Securities  Act") or
Section  20(a) of the  Securities  And  Exchange  Act of 1934,  as amended  (the
"Exchange  Act")) against any loss,  claims  damages,  liabilities  and expenses
(including  reasonable  attorneys' fees, costs and expenses)  resulting from any
untrue  statement or alleged untrue  statement of material fact contained in the
registration  statement,  prospectus or preliminary  prospectus or any amendment
thereof or supplement  thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the  statements  therein
not  misleading,  but only to the  extent  that such  actual or  alleged  untrue
statement or omission is contained in or omitted from any information  furnished
to GTS in writing by the Stockholder for use therein.


<PAGE>

     (iii) any person entitled to indemnification under this Section 2.5(b) will
(a) give  prompt  written  notice to the  indemnifying  party of any claim  with
respect to which it seeks  indemnification;  provided,  that the failure to give
such  notice  shall  not  relieve  the  indemnifying  party  of its  obligations
hereunder;  and,  except to the extent that the  indemnifying  party is actually
prejudiced  by the failure to give  notice;  and (b) unless in such  indemnified
party's reasonable  judgment a conflict of interest between such indemnified and
indemnifying  parties  may  exist  with  respect  to  such  claim,  permit  such
indemnifying  party to assume the defense of such claim with counsel  reasonably
satisfactory to the indemnified party and such indemnifying party shall promptly
and vigorously  assume such defense at its cost and expense.  If such defense is
assumed,  the  indemnifying  party will not be subject to any  liability for any
settlement made by the  indemnified  party without its consent (but such consent
shall not be unreasonably  withheld).  An indemnifying party who is not entitled
to, or elects not to, assume the defense of a claim shall promptly pay all costs
and expenses of the indemnified  party's  defense,  but will not be obligated to
pay the fees and expenses of more than one counsel for each party indemnified by
such indemnifying party with respect to such claim.

                                   ARTICLE III

service,  or (iii) avoiding the imposition of any fine or penalty, in any manner
which is in violation of any applicable ordinance, regulation or law.

     Section 4.32 Related  Party  Transactions.  Except as disclosed in Schedule
4.32, and except for  compensation and related  arrangements  with employees for
services rendered consistent with past practices, no current or former director,

                     Representations and Warranties of GTS
                             And Merger Subsidiary

     In order to induce CCI and the Stockholder to enter into this Agreement and
to consummate the transactions contemplated under this Agreement, GTS and Merger
Subsidiary, jointly and severally, hereby make the following representations and
warranties each of which is relied upon by CCI and the Stockholder regardless of
any other action, omission to act, investigation made or information obtained by
CCI or the Stockholder:

     Section 5.1  Organization,  Power and Authority.  GTS and Merger Subsidiary
are  corporations  duly  organized  and validly  existing  under the laws of the
States of Delaware and New Jersey,  respectively,  with full corporate power and
authority to enter into this Agreement and perform their  obligations under this
Agreement.  GTS is  duly  qualified  as a  foreign  corporation  and is in  good
standing  under  the laws of each  jurisdiction  in  which  the  conduct  of its
business or the  ownership of its assets  requires  such  qualification,  except
where the failure to so qualify would not result in a material adverse effect on
GTS or its business.

     Section 5.2 Due Authorization;  Binding Obligation. The execution, delivery
and performance of this Agreement, the Promissory Note, the Employment Agreement
and all other agreements contemplated by this Agreement, the consummation of the
transactions contemplated by this Agreement and the issuance of the Common Stock
have been duly  authorized by all necessary  corporate  action of GTS and Merger
Subsidiary.  This  Agreement  has been duly  executed  and  delivered by GTS and
Merger  subsidiary  and is the valid and  binding  obligation  of GTS and Merger
subsidiary,  enforceable in accordance with its terms. Neither the execution and
delivery of this Agreement nor the consummation of the transactions contemplated
by this  Agreement  will:  (i)  conflict  with or violate any  provision  of the
articles  of  incorporation  or  by-laws  of GTS,  or of any law,  ordinance  or
regulation  or any  decree  or order of any  court  or  administrative  or other
governmental  body which is either  applicable  to,  binding upon or enforceable
against GTS; (ii) result in any material breach of or default under any material
mortgage, contract, agreement,  indenture, will, trust or other instrument which
is either binding upon or enforceable against GTS or its assets; (iii) result in
any breach of or default under any contract;  (iv) violate any legally protected
right of any  individual  or  entity;  or (v)  impair  or in any way  limit  any
material governmental license,  approval,  permit or authorization.  Attached to
this Agreement as Exhibi N are true, correct and complete copies of the Articles
of Incorporation, as amended, and Bylaws, as amended, of GTS.

     Section  5.3  Shares.  When  issued  in  accordance  with the terms of this
Agreement,  the GTS  Stock to be  issued  to the  Stockholder  shall be  validly
issued,  fully paid and  non-assessable and shall be free and clear of any liens
or encumbrances whatsoever.


     Section 5.4  Consents and  Approvals.  The  execution  and delivery of this
Agreement by GTS does not,  and the  performance  of this  Agreement by GTS will
not, require GTS to obtain any consent, approval,  authorization or other action
by,  or to make  any  filing  with  or  notification  to,  any  governmental  or
regulatory authority.


<PAGE>

     Section 5.5 SEC Reports.  GTS has delivered to the  Stockholder  its Annual
Report on Form 10-KSB for the fiscal year ended December 31, 1996 ("10-K"),  and
its Quarterly Reports on Form 10-QSB for the quarters ended March 31, 1997, June
30, 1997 and September 30, 1997  ("10-Qs") and  collectively,  with the 8-Ks and
the 10-K, the "SEC Filings").  Each of the SEC Filings,  including the financial
statements contained therein, as of their filing dates, complied in all material
respects with the  requirements of the rules and regulations  promulgated by the
SEC with respect thereto and did not contain any untrue  statement of a material
fact or omit to state a material fact required to be stated therein or necessary
in order to make the statements  therein,  in light of the  circumstances  under
which they were made, not misleading.  GTS has made all filings  required by the
SEC and other  state and federal  regulatory  agencies  for all  periods  ending
before  the  Closing  Date  and  there  are  no  agreements,  waivers  or  other
arrangements providing for an extension of time with respect to any such filing.
To its knowledge,  GTS is in material compliance with all applicable  securities
laws and regulations and there are no actions suits, proceedings, investigations
or  claims  now  threatened  or  pending  against  GTS in any forum nor are such
matters  currently under discussion with any  governmental  authority and GTS is
not aware of any matter which is reasonably likely to cause such actions, suits,
proceedings, investigations or claims to arise.

     Section 5.6 Brokers. No broker,  finder or investment banker is entitled to
any  brokerage,  finder's  or other fee or  commission  in  connection  with the
transactions  contemplated by this Agreement based upon  arrangements made by or
on behalf of GTS.


     Section  5.7  No  Undisclosed  Liabilities.   GTS  has  no  liabilities  or
obligations  (whether  secured,   unsecured,   absolute,  accrued,  asserted  or
unasserted, contingent or otherwise) of any nature, whether as principal, agent,
partner,  co-venturer,  guarantor  or in any  other  capacity  except:  (i)  the
liabilities  and  obligations of GTS that are reflected in the Report filed with
the SEC on Form 10-QSB for the period ending  September 30, 1997 and only to the
extent reflected; (ii) liabilities incurred or accrued in the ordinary course of
business since  September 30, 1997 which do not,  either  individually or in the
aggregate,  have a material adverse effect on the financial condition of GTS; or
(iii) liabilities otherwise disclosed in Schedule 5.7.


<PAGE>

                  Section 5.8 Litigation,  Orders and Decrees.  Except as listed
on  Schedule   5.8,   there  are  no  actions,   suits,   claims,   governmental
investigations  or  arbitration  proceedings  pending  or to the  best of  GTS's
knowledge,  threatened  against or affecting  GTS or the  business,  assets,  or
financial  condition  of GTS and there are no facts or  circumstances  which are
reasonably  likely  to  create a basis  for any of the  foregoing.  There are no
outstanding  orders,  decrees  or  stipulations  issued by any  local,  state or
federal  judicial  authority  in any  proceeding  to which GTS is or was a party
which may have a material adverse effect on GTS.

                  Section  5.9  Labor  Matters.  GTS  is  not  a  party  to  any
collective bargaining  agreements with its employees.  GTS is in compliance with
all federal, state and local laws regarding employment and employment practices,
conditions of employment,  wages and hours and occupational  laws, the violation
of which  would have a material  adverse  effect on GTS.  GTS is not  engaged in
unfair  labor  practices,  and  there are no unfair  labor  practice  complaints
pending or threatened  against GTS before the National Labor  Relations Board or
any  other  governmental  or  regulatory  board  or  agency  performing  similar
functions.  There is no labor strike, slowdown, work stoppage or dispute pending
or threatened against or involving GTS. To the best of GTS's knowledge,  none of
GTS's  employees  are engaged in organizing or are members of any union or other
employee group that is seeking recognition as a bargaining unit.


     Section  5.10  Absence of Changes.  Except as set forth in  Schedule  5.10,
since September 30, 1997,  there has not been any material adverse change in the
financial  condition,  assets,  liabilities,  business or operations of GTS that
would  materially  impact GTS's financial  condition or its ability to fully and
timely comply with each of its obligations hereunder.


     Section 5.11 Accuracy of Documents,  Exhibits and Schedules. All contracts,
instruments,  agreements and other  documents  delivered by GTS to CCI for CCI's
review in  connection  with this  Agreement  and the  transactions  contemplated
hereby,  including all articles of incorporation,  by-laws,  corporate  minutes,
stock record books and tax returns are true,  correct and complete copies of all
those contracts,  instruments,  agreements and other documents. All Exhibits and
Schedules to this Agreement are true correct and complete as of the date hereof.
No  statement  contained  in  this  Agreement  or in any  certificate,  Exhibit,
Schedule or  instrument  furnished  to CCI  pursuant to the  provisions  of this
Agreement  or  in  connection  with  the   consummation   of  the   contemplated
transactions contains or will contain any untrue statement of a material fact or
does not  include or omit to state a material  fact  necessary  in order to make
those statements not misleading.


<PAGE>

     Section  5.12  Environmental  Matters;  Health and Safety  Laws.  GTS is in
material  compliance  with all  federal,  state  and  local  laws,  regulations,
permits,  orders and  decrees  relating to  protection  of the  environment  and
employee health and safety ("GTS Applicable Requirements"). GTS has not received
any notice to the effect that its operations  are not in compliance  with any of
the GTS Applicable Requirements or the subject of any governmental investigation
evaluating  whether any remedial action is needed to respond to a release of any
toxic or hazardous waste or other substance  (including petroleum products) into
the environment  and GTS knows of no facts which could  constitute the basis for
any thereof.

     Section 5.13 Nature and Survival of Representations  and Warranties of GTS.
All  statements  contained  in any  Schedule,  document,  certificate  or  other
instrument  delivered  by or on behalf of GTS pursuant  hereto or in  connection
with the  transactions  contemplated  hereby  shall be  deemed  representations,
warranties, covenants and agreements made by GTS. Each representation, warranty,
covenant and  agreement  made by GTS shall survive the Closing for eighteen (18)
months. The representations, warranties, covenants and agreements made by GTS in
this Agreement shall not be affected or deemed waived by reason of the fact that
CCI  or  its   representative   knew  or  should   have   known  that  any  such
representations, warranties, covenants or agreement is or might be inaccurate in
any  respect.  Any  furnishing  of  information  to CCI by GTS  pursuant  to, or
otherwise in connection with, this Agreement, including, without limitation, any
information contained in any document,  contract, book or record of GTS to which
CCI had access or any  information  obtained by, or made  available to, CCI as a
result  of any  investigation  made by or on  behalf of CCI prior to the date of
this  Agreement,  shall not affect  CCI's  right to rely on any  representation,
warranty,  covenant or agreement  made by GTS in this Agreement and shall not be
deemed a waiver thereof.

                                   ARTICLE VI

                          Covenants of the Stockholder

     Section  6.1 Further  Assurances.  From time to time after the date of this
Agreement,  the Stockholder shall execute and deliver such other instruments and
shall take such other actions as GTS may  reasonably  request to effectuate  the
transactions contemplated by this Agreement.
               
     Section 6.2 Restrictive Covenant.

     (a) To assure that GTS will realize the value inherent in the  transactions
contemplated by this Agreement, the Stockholder agrees with GTS that neither the
Stockholder nor any of his Affiliates (except for the Stockholder's  performance
under an Employment  Agreement  with GTS) nor any person or entity  controlling,
controlled by or in any common control with the Stockholder  shall,  directly or
indirectly,  for a period of four (4) years following the date of this Agreement
in any state of the United States of America:


<PAGE>

     (i) own,  manage,  operate,  control or otherwise  engage in a  Competitive
Business (as hereinafter defined);

     (ii) attempt to solicit or solicit the customers or facilities  serviced by
GTS  (including,  without  limitation,  those  acquired  by  GTS  hereunder)  in
connection with a Competitive Business; or

     (iii)  attempt  to  solicit,  solicit  or employ  any  person  employed  or
contracted  by GTS  (except  those  listed  on  Schedule  6.2)  to  leave  their
employment or not fulfill their contractual  responsibility,  whether or not the
employment or  contracting  is full-time or temporary,  pursuant to a written or
oral agreement, or for a determined period or at will.

     As used in this Section 6.2, "Competitive  Business" shall mean the design,
development and/or marketing of prepaid telecommunications products,  including,
without limitation, prepaid phone cards, prepaid cellular products and services,
prepaid  dial tone and related  services,  or prepaid  enhanced  and/or  prepaid
interactive  telecommunications  services and/or products. 

     Notwithstanding   the  foregoing,   in  the  event  GTS  (i)  breaches  its
obligations to pay the Stockholder the amounts due under the Promissory Note and
fails to cure such  breach  after  receipt of written  notice  from  Stockholder
within the time periods  permitted  therein,  or (iii) breaches its  obligations
under Section 2.5 of this Agreement,  then the  Stockholder's  obligations under
this Section 6.2(a) shall cease.

     (b) If Section 6.2(a) of this  Agreement,  as applied to the Stockholder or
any other  person,  is adjudged by a court to be invalid or  unenforceable,  the
same will in no way affect any other provision of that Section or any other part
of this Agreement,  the application of that provision in any other circumstances
or the validity or  enforceability of this Agreement.  If any provision,  or any
part of any provision,  is held to be  unenforceable  because of the duration of
the provision or the geographic  scope of the provision,  the parties agree that
the court making such  determination  will have the power to reduce the duration
and/or geographic scope of the provision to the longest permissible duration and
largest  permissible  geographic  scope,  and/or  to  delete  specific  words or
phrases, and in its reduced form Section 6.2(a) will then be enforced.


<PAGE>

     Stockholder  agrees that he will not, at any time,  directly or indirectly,
(except  in his  duties to GTS or the  Surviving  Corporation)  disclose  to any
person any  information  concerning  the methods of  operation,  sales,  cost or
pricing methods,  employees (number and location),  customers  (names,  needs or
requirements), contracts or agreements of CCI's or GTS's respective businesses.

     Because GTS will be  irreparably  damaged if the provisions of this Section
6.2 are not  specifically  enforced,  GTS  shall be  entitled  to an  injunction
restraining  any violation or  threatened  violation of this Section 6.2, or any
other  appropriate  decree of specific  performance,  without the  necessity  of
showing any actual damage or that monetary damages would not provide an adequate
remedy.  Such  remedies  shall not be exclusive  and shall be in addition to any
other  remedy  which  GTS may have as a result  of any such  violation.  Nothing
contained  in  this  Section  shall  be  construed  as  prohibiting  GTS and its
Affiliates  from pursuing all other  remedies  available to them for a breach of
the provisions of Section 6.2. The Stockholder  further  acknowledges and agrees
that the covenants  contained in Section 6.2 are necessary for the protection of
the CCI's and Surviving  Corporation's  legitimate business  interests,  and are
reasonable in scope and content.

     Section  6.3  Press  Releases.  Neither  the  Stockholder  nor  any  of his
Affiliates  shall  issue or cause to be issued any press  release in  connection
with or  referring to any of the  transactions  contemplated  by this  Agreement
without the express prior written consent of GTS.

     Section  6.4  Non-Use  of Name.  From and  after the date  hereof,  neither
Stockholder  nor any of his  Affiliates  (other than the Surviving  Corporation)
shall  establish  or  otherwise  be  associated  with,  as  an  owner,  partner,
shareholder,   employee  or  otherwise,   any  firm  which   utilizes  the  name
"Centerpiece Communications" or any variant thereof as part of its business name
other than in connection with their  employment by GTS after the Closing Date or
grant  to  any  person  or  entity  the  right  to  use  he  name   "Centerpiece
Communications" or any variant thereof.


     Section 6.5 Lock-Up  Agreements.  Concurrently  with the  execution of this
Agreement,  Stockholder  will execute and deliver to GTS the Lock-Up  Agreement.

     Section 6.6 Employment  Agreement.  Concurrently with the execution of this
Agreement, Stockholder will execute and deliver to GTS the Employment Agreement.

                                Covenants of GTS

     Section  7.1 Further  Assurances.  From time to time after the date of this
Agreement,  GTS shall execute and deliver such other  instruments and shall take
such other actions as the Stockholder  may reasonably  request to effectuate the
transactions contemplated by this Agreement.

     Section  7.2  Disclosure.  GTS will not be  required  to  obtain  the prior
written  consent of the  Stockholder  to disclose  the  existence or any term or
condition of this Agreement if, and only if, GTS believes (based upon the advice
of counsel) such  disclosure is required under the securities laws of the United
States. 

     Section 7.3  Membership of  Purchaser's  Board of Directors.  GTS agrees to
nominate  the  Stockholder  for  membership  to GTS's board of directors at each
annual meeting of its stockholders for so long as the Stockholder (i) remains an
employee  of  GTS  and  (ii)  continues  to  own  at  least  65%  of  the  Stock
Consideration  acquired by him pursuant to this Agreement.  Notwithstanding  the
foregoing,  in the  event  the  Stockholder  is not a  member  of GTS'  board of
directors, the Stockholder shall have the right to terminate his employment with
GTS as provided in Section 3.7 of the Employment Agreement.

     Section 7.4 Employment  Agreement.  Concurrently with the execution of this
Agreement,  GTS will  execute  and  deliver to the  Stockholder  the  Employment
Agreement.

     Section 7.5 Promissory Note and Security  Agreement.  Concurrently with the
execution of this Agreement, GTS will execute and deliver to the Stockholder the
Promissory Note and Security Agreement.

between the parties  hereto  relating to: (a)  liabilities or obligations of CCI
(whether absolute, accrued, contingent or otherwise), whether existing as of the
Closing or arising  out of facts or  circumstances  existing  at or prior to the
Closing,  and whether or not those  liabilities or obligations were known at the
time of the Closing (except for those  post-closing  contractual  obligations of
the CCI specifically set forth on Schedule 8.1) including,  without  limitation,
any Losses arising from any tax,  environmental or regulatory  matters;  (b) any

Closing to perform  any of the  ongoing  contractual  obligations  which are set
forth  on  Schedule  8.1.  GTS  agrees  that  any for  which it is to be paid in
connection with the indemnification provided hereunder shall be in the following
order (the "Set-Off Priority"):  (i) recapture of the GTS Stock, up to a maximum
value of $100,000,  at a price per share  recapture price equal to the per share

Stock;  (ii) from amounts  remaining  due and owing from GTS to the  Stockholder
under the Promissory  Note;  (iii) form the Cash  Consideration;  (iv) from cash

relating to: (a) liabilities or obligations of GTS (whether  absolute,  accrued,

(d) any failure  after the  Closing to perform  any of the  ongoing  contractual
obligations which are set forth on Schedule 8.1.

     Section  8.3   Procedure   for  Claims.   A  Party   required  to  make  an
indemnification payment pursuant to this Agreement  ("Indemnifying Party") shall
have no liability  with  respect to any claim or  otherwise  with respect to any
covenant,  representation,  warranty, agreement, undertaking or obligation under
this Agreement unless the Party entitled to receive such indemnification payment
("Indemnified  Party") gives notice to the Indemnifying Party specifying (i) the
covenant,  representation  or warranty,  agreement,  undertaking  or  obligation
contained herein which it asserts has been breached,  (ii) in reasonable detail,
the nature and dollar amount of any Claim the Indemnified Party may have against
the Indemnifying Party by reason thereof under this Agreement, and (iii) whether
or not the Claim is a Claim by a person, firm,  corporation or government entity
other than a party hereto or any affiliate of such party ("Third-Party Claims").
With respect to  Third-Party  Claims,  an  Indemnified  Party (a) shall give the
Indemnifying  Party prompt notice of any Third-Party  Claim, (b) prior to taking
any action  with  respect to such  Third-Party  Claim,  shall  consult  with the
Indemnifying Party as to the procedure to be followed in defending, settling, or
compromising  the Third-Party  Claim, (c) shall not consent to any settlement or
compromise  of  the  Third-Party  Claim  without  the  written  consent  of  the
Indemnifying Party (which consent,  unless the Indemnifying Party has elected to
assume the exclusive defense of such Claim,  shall not be unreasonably  withheld
or delayed) and (d) shall permit the  Indemnifying  Party,  with the Indemnified
Party's prior written consent, which consent shall not be unreasonably withheld,
if it so elects,  to assume the  exclusive  defense  of such  Third-Party  Claim
(including,  except as provided in the last  sentence of this  Section  8.3, the
compromise or settlement thereof) at its own cost and expense.  The Indemnifying
Party will not  compromise  or settle any  Third-Party  Claim without the writte
consent of the  Indemnified  Party if the relief provided is other than monetary
damages and such relief would materially adversely affect the Indemnified Party.

                               EMPLOYMENT AGREEMENT

         THIS EMPLOYMENT  AGREEMENT (the "Agreement"),  dated as of January ___,
1998,  is entered  into between J. MARK  RUBENSTEIN,  residing at 29 Duer Place,
Weehawken,   New  Jersey  07087  ("Executive"),   and  GLOBAL  TELECOMMUNICATION
SOLUTIONS,  INC., a Delaware  corporation  having its  principal  office at 5697
Rising Sun Avenue, Philadelphia, Pennsylvania 19120 ("Company").

         WHEREAS,  THE  Company and  Executive  are  entering  into a Merger And
Reorganization  Agreement  (the  "Merger  Agreement")  under  which  Centerpiece
Communications,  Inc.  ("CCI")  will be  merged  with and  into a  wholly  owned
subsidiary of the Company; and

         WHEREAS, Executive is the sole shareholder of CCI; and

         WHEREAS,  a material term of the Merger  Agreement is the employment of
Executive by the Company in accordance  with the terms and  conditions set forth
herein; and

     WHEREAS,  the Company and Executive desire to provide for the employment of
Executive by the Company on the terms set forth herein;

         IT IS AGREED:

         1.       Employment, Duties and Acceptance.

                  1.1 The Company hereby employs Executive as its Vice President
- - -Wholesale Sales to supervise and control the Company's  wholesale sales. All of
Executive's  powers and authority in any capacity  shall at all times be subject
to the  reasonable  direction  and  control  of the  Company's  Chief  Operating
Officer.

                  1.2 The Chief  Operating  Officer may assign to Executive such
other  executive  duties for the Company or any Affiliate (as defined in Section
5.1) as are  consistent  with  Executive's  status as Vice  President  Wholesale
Sales.

                  1.3  Executive  accepts such  employment  and agrees to devote
substantially  all  of  his  business  time,   energies  and  attention  to  the
performance of his duties.  Executive shall perform his duties  primarily in and
from the Company's offices located in the Northern New Jersey metropolitan area.

         2.       Compensation and Benefits.

                  2.1  Subject to any  increases  in salary  pursuant to Section
2.2,  the  Company  shall  pay to  Executive  a base  salary  ("Salary")  at the
aggregate rate of $150,000 per annum during the Employment Term (as such term is
defined in  Section  3.1,  below).  Executive's  Salary  shall be paid in equal,
periodic   installments,   in  accordance  with  the  Company's  normal  payroll
procedures  and shall be subject to  withholding  taxes and other normal payroll
deductions.

                  2.2 The Company shall annually review Executive's performance.
Based upon such review and such other factors as the Company may  consider,  the
Company may determine to increase  Executive's  salary and/or award  Executive a
bonus (which bonus shall be payable in cash or securities of the Company).


<PAGE>



Notwithstanding  the  foregoing,  Executive  understands  that Company shall not
obligated  under  any  circumstances,  to award any such  increase  in salary or
bonus.

                  2.3 Executive  shall be entitled to such  medical,  dental and
disability  insurance and other such benefits  which are no less  favorable than
generally  afforded to other senior executives of the Company,  subject to appli
cable waiting periods and other generally applicable conditions. Executive shall
be  entitled to three weeks of paid  vacation in each  employment  year and to a
reasonable number of other paid days off for religious and personal reasons (and
such paid sick  leave in  accordance  with the  Company's  policies  generally).
Executive  acknowledges  that the Company may, from time to time,  apply for and
take out in its own name and at its expense, life, health, disability,  accident
or other insurance, including key man insurance, upon Executive that the Company
may deem necessary and advisable to protect its interests  hereunder.  Executive
agrees to submit to medical or other reasonable  examination  necessary for such
purpose  and to  assist  and  cooperate  with  the  Company  in  procuring  such
insurance;  and  Executive  acknowledges  that he shall have no right,  title or
interest in or to such insurance.

                  2.4  The  Company  will  pay or  reimburse  Executive  for all
transportation,  hotel and other  expenses  reasonably  incurred by Executive on
business trips and for all other ordinary and reasonable  out-of-pocket expenses
actually  incurred by him in the conduct of the business of the Company  against
itemized  vouchers  submitted  with  respect to any such  expenses  approved  in
accordance with customary procedures.

         3.       Term and Termination.

                  3.1 The term of this  Agreement  commences  as of January  31,
1998 and shall continue until January 31, 2001 (the "Employment  Term"),  unless
sooner terminated or extended as herein provided.

                  3.2 If Executive dies during the term of this Agreement,  this
Agreement shall  thereupon  terminate.  Notwithstanding  such  termination,  the
Company  shall (i) pay to the legal  representative  of  Executive's  estate the
Salary due  Executive  pursuant to paragraph  2.1 hereof for a period of one (1)
year from the date of his death (the "Benefit  Period") and (ii) ensure that the
health  insurance  afforded  such  legal  representative  prior  to the  date of
Executive's  death is continued  during the Benefit Period;  provided,  however,
that the Company shall be entitled to deduct the cost of  continuing  the health
insurance from the Executive's salary during the Benefit Period. Notwithstanding
anything  contained  herein to the contrary,  the  termination  of the Agreement
under this section shall not affect  Executive's  rights (or those of his lawful
heirs or assigns),  including Executive's rights as a shareholder of the Company
or the Company's  obligations under the transactions  contemplated by the Merger
and  Reorganization  Agreement (the "Merger") and all other  agreements  entered
into as a part of the Merger.

                  3.3 The Company, by written notice to Executive, may terminate
this  Agreement if  Executive  shall fail  because of illness or  incapacity  to
render, for six (6) consecutive months,  services of the character  contemplated
by this  Agreement.  To enforce this  provision,  the Company  shall  deliver to
Executive  a  written  statement,  to be signed by an  officer  of the  Company,
setting  forth  its  intent  to  terminate  this  Agreement,  the  date on which
termination will occur and


<PAGE>



all reasons for the  termination at least ten (10) days prior to the termination
date. Notwithstanding anything contained herein to the contrary, the termination
of the  Agreement  under this section  shall not affect  Executive's  rights (or
those of this  lawful  heirs or  assigns),  including  Executive's  rights  as a
shareholder of the Company or the Company's  obligations  under the transactions
contemplated  by the Merger and all other  agreements  entered into as a part of
the Merger.


                  3.4 The  Company,  by not less than thirty  (30) days  written
notice to Executive,  may terminate this Agreement without cause at any time. In
the event of such  termination the Company shall pay to Executive the salary and
benefits due Executive pursuant to Article 2 through the full Employment Term as
provided in Section 3.1.  Notwithstanding  such  termination,  the provisions of
paragraph 4 shall  survive.  In  addition,  notwithstanding  anything  contained
herein to the contrary,  the  termination  of the  Agreement  under this section
shall not affect  Executive's rights (or those of this lawful heirs or assigns),
including  Executive's  rights as a shareholder  of the Company or the Company's
obligations  under the  transactions  contemplated  by the  Merger and all other
agreements entered into as a part of the Merger.

                  3.5 The Company,  by written notice to Executive setting forth
a  detailed  explanation  of the  circumstances  giving  rise  to the  right  to
terminate, may terminate this Agreement for cause. As used herein, "cause" shall
include, but not be limited to: (a) the refusal or failure by Executive to carry
out specific  directions of the Chief Operating  Officer which are of a material
nature and consistent  with his status as Vice President - Wholesale  Sales,  or
the refusal or failure by  Executive to perform a material  part of  Executive's
duties hereunder; (b) the commission by Executive of a material breach of any of
the provisions of this  Agreement;  (c) common law fraud or dishonest  action by
Executive  in his  relations  with the  Company  or any of its  subsidiaries  or
affiliates,  or with any  customer or business  contact of the Company or any of
its  subsidiaries  or  affiliates  ("dishonest"  for these  purposes  shall mean
Executive's  knowingly  or  recklessly  making  of a  material  misstatement  or
omission for his personal  benefit);  or (d) the  conviction of Executive of any
crime involving an act of moral  turpitude.  Notwithstanding  the foregoing,  no
"cause" for  termination  shall be deemed to exist with  respect to  Executive's
acts described in clauses (a) or (b) above,  unless the Company shall have given
written notice to Executive, signed by an officer of the Company, specifying the
"cause" with reasonable  particularity  and, within ten (10) business days after
such notice,  Executive  shall not have cured or eliminated the problem or thing
giving rise to such "cause;" provided,  however,  that a breach of any provision
of clauses (a) or (b) above, involving the same or substantially similar actions
or conduct for which the Company  previously gave notice of termination and with
respect  to  which,  Executive   satisfactorily  cured,  shall  be  grounds  for
termination   for  cause  without  any  additional   notice  from  the  Company.
Notwithstanding  such termination,  the provisions of paragraph 4 shall survive.
In addition,  notwithstanding  anything  contained  herein to the contrary,  the
termination  of the Agreement  under this section  shall not affect  Executive's
rights (or those of this lawful heirs or assigns),  including Executive's rights
as a  shareholder  of  the  Company  or  the  Company's  obligations  under  the
transactions contemplated by the Merger and all other agreements entered into as
a part of the Merger.

                  3.6 The Executive,  by written  notice to the Company  setting
forth a detailed  explanation of the  circumstances  giving rise to the right to
terminate, may terminate this Agreement for cause if the Company materially


<PAGE>



breaches any of the provisions of this Agreement. Notwithstanding the foregoing,
the Executive shall not have grounds for termination unless Executive shall have
given  written  notice to the  Company  specifying  the breach  with  reasonable
particularity and, within ten (10) days after such notice, the Company shall not
have cured or  eliminated  the  problem  or thing  giving  rise to such  breach;
provided,  however,  that a breach of any provision of this Agreement  involving
the same or  substantially  similar  actions or conduct for which the  Executive
previously  gave notice of  termination  and with respect to which,  the Company
satisfactorily  cured,  shall be grounds for  termination  for cause without any
additional  notice from the Executive.  In the event of termination by Executive
under this  Section  3.6,  the  Company  shall pay to  Executive  the Salary due
Executive  pursuant  to  paragraph  2.1  hereof  through  the  Employment  Term.
Notwithstanding  such  termination,  the provisions of paragraph 4 shall survive
termination if the Company  continues to pay Executive the Salary as provided in
the  immediately  preceding  sentence.  In  addition,  notwithstanding  anything
contained  herein to the contrary,  the  termination of the Agreement under this
section  shall not affect  Executive's  rights (or those of this lawful heirs or
assigns),  including  Executive's  rights as a shareholder of the Company or the
Company's obligations under the transactions  contemplated by the Merger and all
other agreements entered into as a part of the Merger.

         3.7  Executive,  by not less than  thirty (3o) days  written  notice to
Company may terminate this Agreement  without cause at any time. In the event of
termination   under  this  Section  3.7,  the  Company's   prospective   payment
obligations  under  Article 2 shall  terminate  simultaneously  with the date on
which the Executive leaves Company's employ. Notwithstanding such termination by
Executive,  the provisions of Article 4 shall survive termination.  In addition,
notwithstanding  anything  contained herein to the contrary,  the termination of
the Agreement under this section shall not affect  Executive's  rights (or those
of this lawful heirs or assigns),  including Executive's rights as a shareholder
of the Company or the Company's obligations under the transactions  contemplated
by the Merger and all other agreements entered into as a part of the Merger.

         3.8  Notwithstanding any other provision contained herein, in the event
of a termination  for cause  pursuant to Section 3.6 or 3.7 hereof,  the parties
shall promptly submit the determination of whether cause for termination existed
to binding  arbitration.  The  arbitration  shall be held  before  the  American
Arbitration  Association  (the "AAA") at its office in New York, New York, shall
be administered  under the AAA's  Commercial  Arbitration  Rules and Section 6.3
shall be applicable to such  arbitration.  The parties agree to jointly  request
that the  arbitration  hearing be concluded and a decision  rendered  within 120
days after the end of the cure period as defined in the  applicable  Section 3.6
or 3.7.  The  arbitrator's  decision  shall be  final  and  non-appealable.  The
prevailing party in any such arbitration shall be entitled to reimbursement from
the  non-prevailing  party for all of its reasonable  arbitration and attorneys'
fees and costs.  Upon  termination  for cause as provided in Section 3.6 or 3.7,
the Company  shall pay  Executive's  Salary and bonus into a third party  escrow
account to be held in such account  pending final  resolution of the arbitration
hearing as set forth in this  Section.  In the event the  Arbitrator  determines
that the Company's  termination  of Executive was based upon cause as defined in
Section 3.6, then all funds previously  deposited into escrow hereunder shall be
immediately  returned  to the  Company  and the  Company  shall  have no further
obligation hereunder.  In the event the Arbitrator determines that the Company's
termination  of  Executive  was not based upon cause as defined in Section  3.6,
then all funds  previously  deposited into escrow hereunder shall be immediately
released to the Executive


<PAGE>



and the Company shall immediately  commence providing  Executive with his Salary
and  benefits  for the  remaining  term  of this  Agreement.  In the  event  the
Arbitrator  determines  that the  Executive's  termination of this Agreement was
based upon cause as defined in Section 3.7, then all funds previously  deposited
into escrow hereunder shall be immediately released to Executive and the Company
shall immediately  commence providing Executive with his Salary and benefits for
the remaining term of this  Agreement.  In the event the  Arbitrator  determines
that the  Executive's  termination of this Agreement was not based upon cause as
defined  in  Section  3.7,  then all  funds  previously  deposited  into  escrow
hereunder  shall be  immediately  returned to the Company and the Company  shall
have no further obligation hereunder.

         4.       Protection of Confidential Information.

                  4.1      Executive acknowledges that:

     (a) As a result of his employment  with the Company,  Executive will obtain
secret and  confidential  information  concerning  the  business  of the Company
and/or  its  subsidiaries  and  affiliates  (referred  to  collectively  in this
paragraph  4  as  the  "Company"),   including,  without  limitation,  financial
information, designs and other proprietary rights, trade secrets and "know-how,"
customers and sources ("Confidential Information").

     (b) The Company will suffer  substantial  damage which will be difficult to
compute if, during the period of his employment  with the Company or thereafter,
Executive  should  enter a  business  competitive  with the  Company  or divulge
Confidential  Information.  (c) The  provisions of this Agreement are reasonable
and necessary for the protection of the business of the Company.

     4.2 Executive  agrees that he will not at any time,  either during the term
of  this  Agreement  or  thereafter,   divulge  to  any  person  or  entity  any
Confidential  Information  obtained  or  learned  by  him  as a  result  of  his
employment with, or prior retention by, the Company, except (i) in the course of
performing  his  duties  hereunder;  (ii)  with the  Company's  express  written
consent;  (iii) to the extent that any such  information is in the public domain
other  than  as a  result  of  Executive's  breach  of any  of  his  obligations
hereunder;  or (iv) where  required to be disclosed by court order,  subpoena or
other  government  process.  If Executive  shall be required to make  disclosure
pursuant to the provisions of clause (iv) of the preceding  sentence,  Executive
promptly,  but in no event more than  seventy two (72) hours  after  learning of
such  subpoena,   court  order,  or  other  government  process,  shall  (unless
prohibited  by law,  regulation,  court  order,  administrative  decree or other
governmental  action)  notify,  by  personal  delivery or by  electronic  means,
confirmed by mail, the Company and, at the Company's  expense,  Executive shall:
(a) take all  reasonably  necessary and lawful steps  required by the Company to
defend against the enforcement of such subpoena, court order or other government
process, and (b) permit the Company to intervene and participate with counsel of
its choice in any proceeding relating to the enforcement thereof.

     4.3 Upon  termination  of his employment  with the Company,  Executive will
promptly deliver to the Company all memoranda, notes, records, reports, manuals,
drawings,  blueprints and other documents (and all copies  thereof)  relating to
the business of the Company and all property associated therewith,  which he may
then possess or have under his control; provided, however, subject


<PAGE>



to  Executive's  obligations  under  this  Section  4, that  Executive  shall be
entitled to retain copies of such documents reasonably necessary to document his
financial   relationship   (both  past  and  future)  with  the   Company.   4.4
[Intentionally left blank] 4.5 [Intentionally left blank]

reimbursed  by the other  party  for the  reasonable  attorneys'  fees and costs
incurred by the prevailing party.

     4.7 If any provision of Section 4.2 is held to be unenforceable  because of
the scope,  duration  or area of its  applicability,  the  tribunal  making such
determination shall have the power to modify such scope,  duration,  or area, or
all of them, and such  provision or provisions  shall then be applicable in such
modified form.

     4.8 The  provisions of this  paragraph 4 shall survive the  termination  of
this Agreement for any reason.
