Note 2 - Income Taxes

      There is no provision for federal or state income taxes and for foreign 
      income taxes for the first quarter of 1995, since the Company had 
      incurred operating losses since inception.  In addition, the Company 
      has fully reserved the potential future tax benefits resulting from the 
      utilization of U.S. net operating loss carryforwards, Polish operating 
      loss carryforwards and other temporary timing differences.

Note 4 - Net Income (loss) per share

      The net income (loss) per common and common equivalent share is based 
      on the weighted average number of shares of common stock outstanding.  
      For 1995, common equivalent shares include stock options for 128,394 
      shares granted at prices below the average market price of $3.36 per 
      share, as if they were outstanding for the entire quarter, calculated 
      by the treasury stock method in accordance with Securities and Exchange 
      Commission Staff Accounting Bulletin requirements.  
      
      For 1996, common equivalent shares include stock options and warrants 
      for 376,394 shares granted at prices below the average fair market 
      price at which the Company's common stock traded during the period, as 
      if they were outstanding for the entire quarter, calculated by the 
      treasury stock method as described above.
      
      The average market price during each of the periods presented has been 
      used in the calculation of equivalent shares in all periods presented 
      as this results in the maximum dilutive effect.
      
Note 5 - Investment in operating ventures

      During 1995, the Company made an investment of $2,930 in a Polish joint 
      venture "TELINFO".  The  joint venture was formed to provided 
      telecommunication services in a rural area of Poland.  The Company has 
      a 34 percent interest in the joint venture and has no continuing 
      obligation to fund or guarantee the liabilities of the joint venture.  
      Currently, the joint venture has no significant operations but is 
      seeking a telephone operator's license for the Suwalki, Poland area.
       
      During the first quarter of 1996, the Company invested $98,939 for a 5% 
      interest in a venture with Elterix, a Polish company developing a 
      private network for 70,000 telephone lines.

Note 6 - Business combination

      On April 29, 1996, the Company signed a definitive agreement to acquire 
      all of the stock of Telereunion, a privately owned Delaware 
      corporation.  Telereunion is a telecommunications equipment and service 
      company with operations primarily in Mexico. Under the terms of the 
      acquisition, the Company will issue to the shareholders of Telereunion 
      1,605,000 shares of common stock of the Company, 380,000 shares of 
      non-voting, non-participating preferred stock having an aggregate 
      liquidation preference of $380,000 and warrants to purchase up to 
      2,595,000 additional shares at $2.19.  The warrants would vest and 
      become exercisable, if at all, as the combined companies meet certain 
      specified financial objectives and would expire 7 years after closing.  
      In addition, the Company will convert and amend certain non-qualified 
      options outstanding under the Telereunion 1995 Stock Option and 
      Appreciation Rights Plan to provide for the right to acquire an 
      aggregate of 216,618 shares of Common Stock for an exercise price of 
      $1.35 per share.

             MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                    CONDITION AND RESULTS OF OPERATIONS           
           --------------------------------------------------------

REVENUES from the sale of products increased by $168,632 from $340,606 in the 
first quarter of 1995 to $509,238 in the first quarter of fiscal 1996.  In 
the first quarter of 1996, sales of Point-to-Point microwave equipment 
totaled approximately $85,000, while sales of switching equipment totaled 
approximately $420,000 during this period.  For the first quarter of 1995, 
sales of Point-to-Point microwave and switching equipment approximated 
$150,000 and $190,000, respectively.

COST OF REVENUES increased by $109,951 from $208,210 in the first quarter of 
1995 to $318,161 in the first quarter of fiscal 1996.  The increase in the 
cost of revenues for the first quarter of 1996 as compared to the same period 
in 1995, reflects the increase in sales revenue realized by the Company.

GROSS PROFIT as a percentage of sales decreased by 1% from 39% in the first 
quarter of 1995 to 38% for the first quarter of 1996.  In dollar terms, gross 
profit increased $58,681, from $132,396 to $191,077 over the same time period.

SELLING GENERAL AND ADMINISTRATIVE EXPENSES ("SG&A") increased by 
approximately $53,868 from $347,676 in the first quarter of fiscal 1995 to 
$401,544 in the first quarter of fiscal 1996.  The increase in SG&A reflects 
the Company's continuing efforts to expand its sales and marketing as well as 
technical capabilities, including the Company's efforts to establish itself 
in the Point-to-Point and Point-to-Multipoint microwave markets.  In 
addition, the Company incurred  non-recurring expenses of approximately 
$53,000 relating to a severance package for its former Chairman and Chief 
Executive Officer who resigned on February 29, 1996.

LOSS FROM OPERATIONS decreased by $4,813 from ($215,280) in the first quarter 
of fiscal 1995 to ($210,467) in the first quarter of fiscal 1996.

OTHER INCOME decreased by $32,345 from $69,242 in the first quarter of fiscal 
1995 to $36,897 in the first quarter of fiscal 1996.  Primary components of 
this change were interest income and foreign exchange gain (loss).  The 
Company has realized less interest income when comparing the first quarter of 
1996 to the first quarter of 1995, primarily due to a decrease in the amount 
invested in short term securities as a result of the use by the Company of 
funds for its operations. 

Additionally, the Company experienced a negative impact in the quarter to 
quarter comparison regarding foreign exchange gain (loss).  In the first 
quarter of 1995, the Company posted an exchange gain of $5,300, while in the 
first quarter of 1996 the Company experienced an exchange loss of $2,928. 

NET LOSS increased by $39,186, from a loss of $141,922 in the first quarter 
of 1995 to a loss of $181,108, in the first quarter of 1996.


                                      8

LIQUIDITY AND CAPITAL RESOURCES. At March 31, 1996 the Company had cash and 
equivalents of approximately $3,400,000.  Since inception, the Company has 
financed its operations primarily through the issuance of debt and equity and 
through cash generated by operations.

On August 10, 1994, the Company issued 1,050,000 shares of its common stock 
and 525,000 redeemable common stock purchase warrants in its initial public 
offering for net cash proceeds of approximately $6,000,000.  Approximately 
$630,000 of these funds were utilized to repay existing indebtedness of the 
Company.  Remaining net proceeds have been and will be used primarily for the 
expansion of current operations, implementation of new product lines, 
inventory acquisition, working capital and other general corporate purposes.

The Company's future cash requirements for the remainder of 1996 and beyond 
will depend primarily upon the level of sales, expenditures on product 
development and enhancements and marketing and the timing of inventory 
purchases.  

OUTLOOK AND UNCERTAINTIES

Future trends for the revenues and profitability of the Company are difficult 
to predict.  The Company continues to face many risks and uncertainties, 
including general and specific market economic risks, the risks associated 
with the continuing conversion of the Polish economy from a communist economy 
to a market economy, competitive factors, the risks of its customers being 
able to obtain financing for their purchases of the Company's products, risks 
of the collectibility of accounts receivable general and the availability of 
products that will be approved for use in the Company's foreign markets.  In 
addition, the Company believes that the markets in which it participates 
could be subject to numerous factors that will contribute to the slow growth 
of its business in those markets, such as the lack of capital for the 
creation of infrastructure, lack of governmental support for the 
telecommunication industry and intense competition from other vendors with 
substantially greater resources and name recognition than the Company.  In 
addition, many of the products or components of the products manufactured by 
the Company are subject to price fluctuations which are beyond the Company's 
control and can affect the Company's ability to price its products 
competitively and, thus, the overall profitability of the Company.  
Furthermore, the Company faces the challenge of maintaining product lines 
that reflect the rapidly improving and changing technology of the 
telecommunications industry.

It is also difficult to predict what effect the Company's proposed purchase 
of the stock of Telereunion will have on the Company's liquidity and capital 
resources.  The exploitation of the opportunities presented by the Mexican 
telephone market are expected to require substantial capital.  To the extent 
Telereunion does not have a positive net cash flow from its operations, it 
can be expected that the Company would have to fund any shortfalls from its 
working capital. In addition, any capital expenditures needed to expand the 
operations of Vextro de Mexico (a subsidiary of Telereunion) would likely be 
funded out of the working capital of the Company.  Any such fundings would 
reduce the funds available to finance and expand the Company's operations in 
eastern Europe.  In addition, further economic crises in Mexico could result 
in the need to fund any cash flow shortfalls of Telereunion and Vextro.

PART II. OTHER INFORMATION

Item 5.  Other Information

      On April 29, 1996, the Company executed a definitive agreement to 
      acquire all of the issued and outstanding shares of Telereunion, Inc., 
      a Delaware corporation ("Telereunion").  The acquisition will be 
      completed by means of a merger between Telereunion and a newly formed 
      subsidiary of the Company.  Upon consummation of the merger, the 
      subsidiary will change its name to Telereunion, Inc.  Telereunion 
      distributes Northern Telcom telecommunications products, as well as 
      Octel voice mail systems and provides conference calling services in 
      Mexico.  Telereunion's operations are conducted through Vextro de 
      Mexico, S.A de C.V. ("Vextro"),  its 97% owned subsidiary organized 
      under the laws of the Republic of Mexico. Although, the acquisition is 
      subject to a number of conditions, management expects that all such 
      conditions will be satisfied in the near term.
      
      Under the terms of the acquisition, the Company will issue to the 
      stockholders of Telereunion, in exchange for the issued and outstanding 
      shares of common stock of Telereunion,: (i) an aggregate of 1,605,000 
      shares of the common stock, $.001 par value per share, of the Company 
      (the "Common Stock"), (ii) warrants for the purchase of an aggregate of 
      2,500,000 shares of Common Stock at an exercise price of $2.19 per 
      share and having a term of seven years (the "Series A Common Stock 
      Warrants"), (iii) warrants for the purchase of an aggregate of 95,000 
      shares of Common Stock at an exercise price of $2.19 per share and 
      having a term of seven years (the "Series B Common Stock Warrants"), 
      and (iv) an aggregate of 380,000 shares of a new series of non-voting, 
      non-participating preferred stock, $.001 par value per share, of the 
      Company (the "Series B Preferred Stock").  In addition, the Company 
      will convert and amend certain non-qualified options outstanding under 
      the Telereunion 1995 Stock Option and Appreciation Rights Plan to 
      provide for the right to acquire an aggregate of 216,618 shares of 
      Common Stock for an exercise price of $1.35 per share.  The options 
      will be fully vested and immediately exercisable.  The consideration to 
      be paid by the Company for the issued and outstanding common stock of 
      Telereunion has been determined by negotiation between the parties.
      
      The exercise price for the Series A Common Stock Warrants and the 
      Series B Common Stock Warrants was calculated based upon the average of 
      the closing price for a share of Common Stock quoted on the Nasdaq 
      Small Cap market for the twenty (20) trading days immediately preceding 
      December 22, 1995, the date of execution of the letter of intent with 
      respect to this acquisition.  The Series A Common Stock Warrants will 
      vest and become exercisable, if at all, upon the Company meeting 
      certain fiscal year earnings per share targets, computed in accordance 
      with the terms of the Series A Common Stock Warrants, as follows: (i) 
      1,000,000 shares if earnings per share equals at least $.315 per share; 
      (ii) an additional 1,000,000 shares if earnings per share (computed to 
      include the effect of the vesting of 2,000,000 shares under the Series 
      A Common Stock Warrants) equals at least $.458 per share; and (iii) an 
      additional 500,000 shares if earnings per share (computed to include 
      the effect of the vesting of all of the Series A 



                                           10


<PAGE>

      Common Stock Warrants) equals at least $.75 per share.  The Series B 
      Common Stock Warrants will vest and become exercisable, 
      if at all, upon the Company achieving a $5,000,000 increase in net 
      shareholder's equity, computed in accordance with the terms of the 
      Series B Common Stock Warrants.  Both the Series A Common Stock 
      Warrants and the Series B Common Stock Warrants are subject to 
      accelerated vesting if the closing price for the Company's Common Stock 
      as quoted on The Nasdaq Stock Market or any other reliable public 
      market is at least $12.00 per share for a period of 90 consecutive 
      trading days during the warrants' terms.

      The Series B Preferred Stock is redeemable by the Company for a price 
      of $1.00 per share upon the attainment of a specified increase in net 
      stockholder's equity or upon the attainment of a specified operating 
      cash flow target.  If a redemption event does not occur within eighteen 
      months of its issuance, the Series B Preferred Stock is automatically 
      terminated.

      In addition to the foregoing terms, three stockholders of Telereunion 
      who are the principal executive officers of Telereunion and its 
      operating subsidiaries will receive three year employment agreements.  
      The Company will also increase the size of its Board of Directors by 
      one member, from its pre-acquisition size of six members to seven.  The 
      three "management" stockholders of Telereunion will join the Board as 
      new directors and four of the six pre-acquisition directors of the 
      Company will comprise the remaining members of the Board.  It is 
      anticipated that Messrs. Panno, Varghese, Kirkland and Efird and 
      Messrs. Landa, Mora and Gudino will comprise the Board of Directors of 
      the Company after consummation of the acquisition.
      
      Mr. Christopher Efird, who is a director of the Company, is also a 
      director of Telereunion.  In addition, Mr. Efird is an employee of 
      Benchmark Equity Group ("Benchmark"), a stockholder of Telereunion.  
      Upon consummation of the acquisition, Mr. Efird will receive, as 
      compensation for his services as an employee of Benchmark, 65,625 
      shares of Common Stock, 37,500 Series A Common Stock Warrants and 
      11,875 Series B Common Stock Warrants, which shares and warrants 
      constitute a portion of the Common Stock and warrants to be issued to 
      Benchmark at the closing of the acquisition.  Mr. Efird originally 
      joined the Board of the Company on November 17, 1995.

     "Redemption Price") in cash upon the surrender of the stock certificates 
     representing each holder's shares of the Series B Non-Voting, 
     Non-Participating Preferred Stock for cancellation.  The number of 
     shares of Series B Non-Voting, Non-Participating Preferred Stock shall

     outstanding from time to time.

     Section 5. LIQUIDATION, DISSOLUTION, OR WINDING UP.

          (a) If a Redemption Condition has been met, but a liquidation

     occurs prior to the payment of the Redemption Price to the holders of 
     the Series B Non-Voting Non-Participating Preferred Stock pursuant to 
     Section 4 above, the Company may, at its sole option and election, make 
     a distribution to the holders of the shares of Series B Non-Voting, 
     Non-Participating Preferred Stock as set forth below in connection with 
     such liquidation, dissolution or winding up in lieu of paying the 
     Redemption Price to such holders.  If the Company makes such an 
     election, no distribution will be made to the holders of shares of stock 
     ranking junior (either as to dividends or upon liquidation, dissolution, 
     or winding up) to the Series B Non-Voting, Non-Participating Preferred 
     Stock unless, prior thereto, the holders of shares of Series B Junior 
     Participating Preferred Stock have received an amount equal to $1.00 for 
     each shares of Series B Non-Voting Preferred Stock (the "Series B 
     Liquidation Preference").  Following the payment of the full amount of 
     the Series B Liquidation 


                                      2

<PAGE>

     Preference, no additional distributions will be made to the holders of 
     shares of Series B Non-Voting Preferred Stock.

          (b) In the event, however, that there are not sufficient assets 
     available to permit payment in full of the Series B Liquidation 
     Preference and the liquidation preferences of all other series of 
     preferred stock, if any, that rank on a parity with the Series B 
     Non-Voting, Non-Participating Preferred Stock, then such remaining 
     assets will be distributed ratably to the holders of such parity shares 
     in proportion to their respective liquidation preferences. 

     Section 6. CONSOLIDATION, MERGER, ETC.  In case the Company enters into 
any consolidation, merger, combination, or other transaction in which the 
shares of Common Stock are exchanged for or changed into other stock or 
securities, cash, and/or any other property, then in any such case the shares 
of Series B Non-Voting, Non-Participating Preferred Stock will at the same 
time be similarly exchanged or changed into securities of the issuer of the 
securities for which the Common Stock is exchanged or which the Common Stock 
is changed into, which securities have a liquidation preferred equivalent to 
that of the shares of Series B Non-Voting, Non-Participating Preferred Stock 
and shall otherwise be equivalent to the Series B Non-Voting, 
Non-Participating Preferred Stock with respect to payment of dividends, 
voting rights, redemption rights, and preference upon the dissolution and 
liquidation of the Company.

     Section 7. AMENDMENT.  The Articles of Incorporation of the Company will 
not be further amended in any manner that would materially alter or change 
the powers, preferences, or special rights of the Series B Non-Voting, 
Non-Participating Preferred Stock so as to affect them adversely without the 
affirmative vote of the holders of a majority or more of the outstanding 
shares of the Series B Non-Voting, Non-Participating Preferred Stock, voting 
separately as a class.

     Section 8. FRACTIONAL SHARES.  Shares of the Series B Non-Voting, 
Non-Participating Preferred Stock may be issued in fractions of a share that 
entitle the holder, in proportion to such holder's fractional shares, to 
participate in distributions and to have the benefit of all other rights of 
holders of shares of Series B Non-Voting, Non-Participating Preferred Stock.

Company on, on March ____, 1996.

further salary payments except those earned prior to the date of termination 
and shall make no further bonus payments.

          8.2  TERMINATION BY THE COMPANY WITHOUT CAUSE. If the Company

competes with the Company, excepting ownership by Employee of no more than one
percent (1%) of the publicly traded common stock or any corporation, (b) without
the express written consent of the Company, accept employment with, or in any 
manner agree to provide, for compensation, services for any other person or 
entity that competes directly or indirectly with the Company, or (c) materially
disrupt, damage, impair or interfere with the business of the Company, whether 
by way of interfering with or soliciting its employees, disrupting its 
relationship with customers, agents, representatives or vendors, or otherwise.

     10.  ARBITRATION.  Any and all disputes or controversies, whether of law 
or fact of any nature whatsoever, arising from or respecting this Agreement 
shall be decided by arbitration by the Judicial Arbitration Mediation Services,
Inc. ("JAMS") in accordance with the rules and regulations of JAMS, or by any 
other body mutually agreed upon by the parties.  Pre-arbitration discovery 
shall be permitted at the request of any party under appropriate protection for
proprietary and confidential business information.

          Before filing a demand for arbitration, a party must send the other 
parties written notice indentifying the matter in dispute and involving the 
procedures in this paragraph.  Such written notice shall be sent promptly after
the party knew or reasonably should have known of an 



<PAGE>

alleged violation of this Agreement.  Within fifteen (15) days after such 
written notice is given, one or more principals of each party shall meet at a 
mutually agreeable location in Dallas, Texas, for the purpose of determining 
whether they can resolve the dispute themselves by written agreement.  If the 
parties fail to resolve the dispute by written agreement within the fifteen-day
(15-day) period, the complaining party may then initiate the arbitration process
by filing a demand with JAMS or such other body as the parties may agree upon.
Nothing in this paragraph shall prevent a party from seeking temporary equitable
relief from JAMS or such other body as the parties may mutually agree upon 
during the fifteen-day (15-day) period in necessary to prevent irreparable harm.

          The arbitrators shall be selected as follows:  the Company and 
Employee shall each select one (1) independent, qualified arbitrator and the 
two (2) arbitrators so selected shall select the third arbitrator.  Any party 
may disqualify any individual arbitrator who is a present or past employee, 
owner, officer, director, relative or consultant to any party hereto or a 
competing organization.

          Arbitration shall take place in Dallas, Texas, or any other 
location mutually agreeable to the parties.  At the request of any party, 
arbitration proceedings will be conducted in the utmost secrecy and, in such 
case, all documents, testimony and records shall be received, heard and 
maintained by the arbitrators in secrecy under seal, available for inspection 
only by the Company or Employee, their respective attorneys, and their 
respective experts, consultants or witnesses who shall agree, in advance and 
in writing, to receive all such information confidentially and to maintain 
such information in secrecy, and make no use of such information except for 
the purposes of the arbitration, until such information shall become 
generally known.

          The arbitrators, who shall act by majority vote, shall be able to 
decree any and all relief of an equitable nature, including but not limited 
to such relief as a temporary restraining order, a temporary injunction, or a 
permanent injunction, and shall also be able to award damages, with or without
any accounting costs.  The decree or judgment of an award rendered by the 
arbitrators may be entered in any court having jurisdiction over the parties.

          Reasonable notice of the time and place of arbitration shall be 
given to persons other than the parties, if such notice is required by law, 
in which case such persons or their authorized representatives shall have the 
right to attend or participate in the arbitration hearing in such manner as the
law shall require.

          If any action is necessary to enforce or interpret the terms of 
this Agreement, the prevailing party shall be entitled to reasonable attorney's
fees, costs and necessary disbursements in addition to any other relief to which
that party may be entitled.

     11.  POWER OF AUTHORITY.  Each party executing this Agreement hereby 
covenants, represents and warrants that he or she has full power of authority 
to execute this Agreement, that no other consents or approvals or any other 
third parties are required or necessary for this Agreement to be so binding 
(except as otherwise herein expressly stated) and that this Agreement shall 
be fully enforceable in accordance with its terms.

     12.  HEIRS, ADMINISTRATORS AND SUCCESSORS.  Except as otherwise provided 
herein, this Agreement shall inure to the benefit of and be binding upon, the 
heirs, administrators and successors of each of the parties hereto.



<PAGE>

     13.  NONASSIGNABILITY.  The Company may assign the benefit of this 
Agreement to any successor  in interest that results from a merger, 
reorganization or acquisition.  Otherwise, no party to this Agreement may 
assign any right hereunder or delegate any duty hereunder without the written 
consent of the other party affected by such assignment or delegation.

     14.  NO ORAL MODIFICATION.  This Agreement may only be changed or modified
and any provisions hereof may only be waived in or by a writing signed by a 
party against whom enforcement or any waiver, change or modification is sought.

     15.  GOVERNING LAW.  This Agreement shall be deemed to be a contract 
made under, and shall be construed in accordance with, the laws of the State 
of Texas.

     16.  SEVERABILITY.  If any portion of this Agreement shall be held illegal,
unenforceable, void or voidable by any court, each of the remaining terms hereof
shall nevertheless remain in full force and effect as a separate contract.

     17.  RIGHT OF SETOFF.  Whenever the Company owes Employee any amounts of 
money by virtue of this Agreement or otherwise, the Company shall be entitled 
to setoff against any such sums due to Employee the amount of any claims that 
the Company has against Employee.  This right of setoff shall also apply to 
amounts due on the date of termination.

     18.  COUNTERPARTS.  This Agreement constitutes the entire agreement and 
understanding of the parties pertaining to the matters set forth herein, and

     AGREEMENT AND PLAN OF MERGER, dated as of April 29, 1996 (this 
"AGREEMENT"), by and among Polish Telephones and Microwave Corporation, a 
Texas corporation (the "PARENT"), PTMC Acquisition Sub, Inc., a Delaware 
corporation and a wholly-owned subsidiary of the Parent (the "MERGER SUB"), 
Telereunion, Inc. (the "COMPANY") and the stockholders of the Company listed 
on the signature pages of this Agreement (the "STOCKHOLDERS").  The Parent 
and Merger Sub are sometimes referred to in this Agreement as the "PARENT 
COMPANIES."

                                  BACKGROUND

     Upon the terms and subject to the conditions of this Agreement and in 
accordance with the Delaware General Corporation Law (the "DELAWARE LAW"), 
Merger Sub will merge with and into the Company (the "MERGER") and, pursuant 
to such Merger the issued and outstanding shares of the Common Stock, $0.001 
par value per share of the Company (the "COMPANY COMMON STOCK"), will be 
converted into the right to receive shares of common stock, $0.001 par value 
per share, of the Parent (the "PARENT COMMON STOCK"), shares of the Series B 
Non-Voting, Non-Participating Preferred Stock, $0.001 par value per share, of 
the Parent (the "PARENT PREFERRED STOCK") and certain Warrants to purchase 
shares of the Parent Common Stock, as set forth in this Agreement.

     The Board of Directors of the Company has determined that the Merger is 
fair to, and in the best interests of, the Company and its stockholders and 
has approved and adopted this Agreement and the transactions contemplated by 
this Agreement.

     The Board of Directors of the Parent has determined that the Merger is 
fair to, and in the best interests of, the Parent and its stockholders and 
has approved and adopted this Agreement and the transactions contemplated by 
this Agreement.

     The Board of Directors of Merger Sub has approved and adopted this 
Agreement and the Parent, as the sole stockholder of Merger Sub, will adopt 
this Agreement promptly after the execution by the parties.

     For federal income tax purposes, it is intended that the Merger qualify 
as a reorganization under the provisions of Section 368(a) of the United 
States Internal Revenue Code of 1986, as amended (the "CODE").

     THEREFORE, in consideration of the foregoing and the respective 
representations, warranties, covenants, and agreements set forth in this 
Agreement and other good and valuable consideration, the receipt and 
sufficiency of which all parties mutually acknowledge, the parties, intending 
to be legally bound, agree as follows:

                                       1

<PAGE>

                                  ARTICLE I                 
                                                            
                   THE MERGER; THE CONVERSION OF SECURITIES 

     1.1  THE MERGER. Upon the terms and subject to the conditions set forth 
in this Agreement, and in accordance with the applicable provisions of the 
Delaware Law, at the Effective Time (as defined in SECTION 1.3), Merger Sub 
will be merged with and into the Company.  As a result of the Merger, the 
separate corporate existence of Merger Sub will cease and the Company will 
continue as the surviving corporation of the Merger (the "SURVIVING 
CORPORATION").

     1.2  CLOSINGS.

          (a) Unless this Agreement has been terminated pursuant to SECTION 
8.1 before the Closing Date, and subject to the satisfaction or waiver of the 
conditions set forth in SECTIONS 6.1 and 6.2, the consummation of the Merger 
(the "CLOSING") will take place at the offices of Hughes & Luce, L.L.P., 1717 
Main Street, Dallas, Texas as soon as practicable (but in any event within 
two business days) after the satisfaction or waiver of the conditions as set 
forth in SECTIONS 6.1 and 6.2, or at such other date, time, and place as the 
Parent and the Company agree; provided, that the conditions set forth in 
SECTION 6.1 and 6.2 have been satisfied or waived at or prior to such time.  
The date on which the Closing takes place is referred to as the "CLOSING 
DATE."  As promptly as practicable on the Closing Date, the parties will 
cause the Merger to be consummated by filing a certificate of merger (the 
"CERTIFICATE OF MERGER") with the Secretary of State of the State of 
Delaware, in such form as required by, and executed in accordance with the 
relevant provisions of, the Delaware Law (the date and time of such filing, 
or such later date or time agreed upon by the Parent and the Company and set 
forth in the Certificate of Merger, being the "EFFECTIVE TIME").  For all Tax 
purposes, the Closing will be effective at the end of the day on the Closing 
Date. 

          (b) Upon the terms and subject to the conditions set forth in this 
Agreement, on the Closing Date (as defined in SECTION 1.2(a)) and at the 
Closing (as defined in SECTION 1.2(a)): 

              (i) the Parent Companies will execute and deliver the other 
agreements, instruments and documents referred to in SECTION 6.1; and

              (ii) the Company will execute and deliver the other agreements, 
instruments and documents referred to in SECTION 6.2.

     1.3  MERGER CONSIDERATION; CONVERSION AND CANCELLATION OF COMPANY COMMON 
STOCK.  At the Effective Time, by virtue of the Merger and without any action 
on the part of the Parent Companies, the Company, or their respective 
stockholders, including, without limitation, the Stockholders:

                                       2

<PAGE>

          (a)  subject to the other provisions of this ARTICLE I, the 
outstanding shares of Company Common Stock (or fraction thereof) issued and 
outstanding immediately prior to the Effective Time will be converted into:

               (i) 1,605,000 shares of the Parent Common Stock;

               (ii) 380,000 shares of the Parent Preferred Stock.  The 
     rights and preferences of the Parent Preferred Stock will conform to a 
     certificate of designation substantially in the form of EXHIBIT A.

               (iii) warrants for the purchase of 2,500,000 shares of Parent
     Common Stock (the "SERIES A COMMON STOCK WARRANTS") substantially in the
     form of EXHIBIT B.

               (iv) warrants for the purchase of 95,000 shares of Parent 
     Common Stock (the "SERIES B COMMON STOCK WARRANTS") substantially in the 
     form of EXHIBIT C.  

          (The Parent Common Stock, the Parent Preferred Stock, the Series A 
     Common Stock Warrants and the Series B Common Stock Warrants are 
     collectively referred to herein as the "PARENT SECURITIES".)  The Parent 
     Securities will be allocated among the Stockholders as set forth on 
     SCHEDULE 1.3(a) hereto (which allocation does not contemplate the 
     issuance of any fractional shares of the Parent's capital stock or 
     warrants to purchase the issuance of any such fractional shares).

Notwithstanding the foregoing, if between the date of this Agreement and the 
Effective Time the outstanding shares of the Parent Common Stock or Company 
Common Stock have been changed into a different number of shares or a 
different class, by reason of any stock dividend, subdivision, 
reclassification, recapitalization, split, combination, exchange of shares, 
or similar occurrence, the number of the Parent Securities into which the 
Company Common Stock will be converted will be correspondingly and 
proportionately adjusted to reflect such stock dividend, subdivision, 
reclassification, recapitalization, split, combination, or exchange of shares.

          (b) Notwithstanding any provision of this Agreement to the contrary,
each share of Company Common Stock held in the treasury of the Company 
immediately prior to the Effective Time will be canceled and extinguished 
without any conversion thereof and no payment will be made with respect 
thereto.

          (c) All shares of the Company Common Stock will cease to be 
outstanding and will automatically be canceled and retired, and each 
certificate previously evidencing the Company Common Stock outstanding 
immediately prior to the Effective Time (other than Company Common Stock 
described in SECTION 1.3(b)) (the "CONVERTED SHARES") will thereafter 
represent the right to receive that number of the Parent Securities 
determined in accordance with SECTION 1.3(a) (the "MERGER CONSIDERATION").  
The holders of certificates previously evidencing Converted Shares will cease 
to have any rights with respect to such Converted Shares except as otherwise 
provided in this Agreement or by applicable law.  Such certificates 
previously evidencing Converted Shares will be exchanged for certificates 
evidencing (i) the whole shares of the Parent 



                                      3


<PAGE>

Common Stock, (ii) the whole shares of the Parent Preferred Stock, (iii) the 
Series A Common Stock Warrants to purchase whole shares of the Parent Common 
Stock and (iv) the Series B Common Stock Warrants to purchase whole shares of 
the Parent Common Stock into which such Converted Shares have been converted 
upon the surrender of such certificates in accordance with the provisions of 
SECTION 1.7, without interest.  No fractional shares of the Parent Common 
Stock will be issued in connection with the Merger.  In addition, after the 
Closing the Telereunion 1995 Stock Option and Appreciation Rights Plan (the 
"TELEREUNION OPTION PLAN") shall be converted and amended as necessary to 
provide for the right to acquire shares of the Parent Common Stock in the 
stead of the Company Common Stock on the same terms and subject to the same 
conditions as now set forth in such Plan as in effect on the date of this 
Agreement.  In addition, each option agreement currently in effect and 
entered into pursuant to the Telereunion Option Plan (the "OPTION AGREEMENT") 
shall be amended after the Effective Time so as to provide for the right to 
exercise the option granted by such option agreement (the "OPTIONS") to 
acquire shares of the Parent Common Stock in the stead of the Company Common 
Stock and so as to prevent the enlargement or dilution of the Option holder's 
and the Company's rights and obligations under such Option Agreement.  With 
respect to each option intended to qualify under SECTION 422 of the Code, the 
amendments shall be consistent with the provisions of 424(a) of the Code.  
Consistent with the provisions above, the amendments to each Option Agreement 
shall be determined by the Board of Directors of the Parent.  The 
determinations of the Board of Directors of the Parent made in good faith 
shall not be subject to review by anyone, and shall be final, binding and 
conclusive on all persons ever interested hereunder.

          (d) Each share of common stock, par value $.01 per share, of Merger
Sub issued and outstanding immediately prior to the Effective Time will be 
converted into one share of common stock, par value $.01 per share, of the 
Surviving Corporation.

     1.4  EFFECT OF THE MERGER. At the Effective Time, the effect of the 
Merger will be as provided in the applicable provisions of the Delaware Law.

     1.5  CERTIFICATE OF INCORPORATION; BYLAWS. At the Effective Time, the 
articles of incorporation of Merger Sub, as in effect immediately prior to 
the Effective Time, will be the articles of incorporation of the Surviving 
Corporation and thereafter will continue to be its articles of incorporation 
until amended as provided in such articles of incorporation and pursuant to 
the Delaware Law.  The bylaws of Merger Sub, as in effect immediately prior 
to the Effective Time, will be the bylaws of the Surviving Corporation and 
thereafter will continue to be its bylaws until amended as provided in such 
bylaws and pursuant to the Delaware Law.

     1.6  DIRECTORS AND OFFICERS. The directors of the Company immediately 
prior to the Effective Time will be the directors of the Surviving 
Corporation, each to hold office in accordance with the articles of 
incorporation and bylaws of the Surviving Corporation, and the officers of 
the Company immediately prior to the Effective Time will be the officers of 
the Surviving Corporation, each to hold office in accordance with the bylaws 
of the Surviving Corporation, in each case until their respective successors 
are duly elected or appointed and qualified.

     1.7  EXCHANGE AND SURRENDER OF CERTIFICATES.

          (a) As soon as practicable after the Effective Time, each holder of 
a certificate previously evidencing Converted Shares will be entitled, upon 
surrender of such certificate to the Parent or its transfer agent, to receive 
in exchange for such certificate a certificate or certificates representing 
the number of (i) the whole shares of the Parent Common Stock, (ii) the whole 
shares of the Parent Preferred Stock, (iii) the Series A Common Stock 
Warrants to purchase whole shares of the Parent Common Stock and (iv) the 
Series B Common Stock Warrants to purchase whole shares of the Parent Common 
Stock into which the Converted Shares so surrendered have been converted as 
described in SECTION 1.3, in such denominations and registered in such names 
as such holder may request consistent with the provisions of this Agreement.  
Until so surrendered and exchanged, each certificate previously evidencing 
Converted Shares will represent solely the right to receive (i) the whole 
shares of the Parent Common Stock, (ii) the whole shares of the Parent 
Preferred Stock, (iii) the Series A Common Stock Warrants to purchase whole 
shares of the Parent Common Stock and (iv) the Series B Common Stock Warrants 
to purchase whole shares of the Parent Common Stock into which the Converted 
Shares have been converted as set forth in SECTION 1.3(a).  Unless and until 
any such certificates are so surrendered and exchanged, no dividends or other 
distributions payable to the holders of record of the Parent Common Stock or 
the Parent Preferred Shares (including, without limitation, the amount of any 
redemption price with respect to the Parent Preferred Stock) as of any time 
on or after the Effective Time will be paid to the holders of such 
certificates previously evidencing Converted Shares; provided, however, that, 
upon any such surrender and exchange of such certificates, there will be paid 
to the record holders of the certificates issued and exchanged therefor (i) 
the amount, without interest, of dividends and other distributions, (including,
without limitation, the amount of any redemption price paid with respect to the
Parent Preferred Stock) if any, with a record date on or after the Effective 
Time theretofore paid with respect to such whole shares of the Parent Common 
Stock or Parent Preferred Stock, and (ii) at the appropriate payment date, the
amount of dividends or other distributions or payments, if any, with a record 
date on or after the Effective Time but prior to surrender and a payment date 
occurring after surrender, payable with respect to such whole shares of the 
Parent Common Stock or Parent Preferred Stock.  Notwithstanding the foregoing,
no party to this Agreement (or the Parent's transfer agent) will be liable to
any former holder of Converted Shares for any cash, the Parent Common Stock, 
the Parent Preferred Stock or dividends or distributions (including without 
limitation, the amount of any redemption price paid with respect to the Parent
Preferred Stock) thereon or any Series A Common Stock Warrants or Series B 
Common Stock Warrants delivered to a public official pursuant to applicable 
abandoned property, escheat, or similar law.

          (b) All of the Parent Securities issued upon the surrender for 
exchange of certificates previously representing Converted Shares in accordance
with the terms of this Agreement will be deemed to have been issued in full 
satisfaction of all rights pertaining to such Converted Shares.  At and after
the Effective Time, there will be no further registration of transfers on the
stock transfer books of the Surviving Corporation of Company Common Stock that
was outstanding immediately prior to the Effective Time. If, after the 
Effective Time, certificates that previously evidenced Converted Shares are 
presented to the Surviving Corporation for any reason, they will be canceled 
and exchanged as provided in this ARTICLE I.

          (f) The Parent Pension Plans, the Parent Welfare Benefit Plans and 
     the Parent Employee Benefit Plans and related trusts and insurance

     fiduciary of any Parent Plan has engaged in any transaction in violation
     of Section 406(a) or (b) of ERISA or Polish law analog or any "prohibited
     transaction" (as defined in Code Section 4975(c)(1)) that would subject 
     the Parent or DTS

     WARRANT TO PURCHASE SHARES OF COMMON STOCK, $0.001 PAR VALUE 
     PER SHARE, OF POLISH TELEPHONES AND MICROWAVE CORPORATION


     THIS CERTIFIES that, for value received, _____________________________ 
(the "Warrantholder"), is entitled, upon the terms and subject to the conditions
hereinafter set forth, to purchase from Polish Telephones and Microwave 
Corporation, a Texas corporation (the "Company"), that number of fully paid and
nonassessable shares of the Company's common stock, $0.001 par value per share
(the "Common Stock"), at the purchase price per share (the "Exercise Price") as
set forth in Section 1 below.  The number of shares and Exercise Price are 
subject to adjustment as provided in Section 10 below.

     1.   NUMBER OF SHARES; EXERCISE PRICE; TERM.

         (a) This Warrant is exercisable for _____________ shares (the "Shares")
of Common Stock at a purchase price of $2.19 per share (the "EXERCISE PRICE").

          (b) Subject to the terms and conditions set forth in this Warrant, 
this Warrant will be exercisable during the term commencing on the date of this
Warrant and ending on May __, 2003 subject to the following vesting schedule:

     (i) This Warrant will vest and become fully exercisable as to 40% of the 
Shares upon the attainment by the Company in any fiscal year after the 
consummation by the Company of its acquisition of all the outstanding shares 
of the capital stock of Telereunion, Inc., a Delaware corporation 
("Telereunion"), of earnings (before depreciation, amortization and non-cash 
charges 



                                      1


<PAGE>

against the earnings of the Company arising as a result of the vesting of this
Warrant and the other similar warrants issued in connection with the acquisition
of the outstanding capital stock of Telereunion) per share of $0.315, computed 
in accordance with generally accepted accounting principles, EXCEPT that only 
1,000,000 of the 2,500,000 shares of Common Stock issuable upon exercise of this
Warrant and the other similar warrants issued in connection with the acquisition
of the outstanding capital stock of Telereunion (the "Total Warrant Shares") 
will be included in the calculation of the earnings per share of the Company in
all instances regardless of whether the closing price for a share of Common 
Stock quoted on the NASDAQ (as defined below) on the date on which such 
calculation is made is more or less than the Exercise Price;

     (ii) This Warrant will vest and become fully exercisable as to an 
additional 40% of the Shares upon the attainment by the Company in any fiscal 
year after the consummation by the Company of its acquisition of all the 
outstanding shares of the capital stock of Telereunion of earnings (before 
depreciation, amortization and non-cash charges against the earnings of the 
Company arising as a result of the vesting of this Warrant and the other 
similar warrants issued in connection with the acquisition of the outstanding 
capital stock of Telereunion) per share of $0.458, computed in accordance 
with generally accepted accounting principles, EXCEPT that only 2,000,000 of 
the Total Warrant Shares will be included in the calculation of the earnings 
per share of the Company in all instances regardless of whether the closing 
price for a share of Common Stock quoted on the NASDAQ on the date on which 
such calculation is made is more or less than the Exercise Price; and PROVIDED
that the percentage of the Shares as to which this Warrant will vest and become
fully exercisable pursuant to this clause (ii) will be increased to 80% of the
Shares if there has been no vesting of the Warrant and the right to exercise 
this Warrant pursuant to the immediately preceding clause (i); and 

     (iii) This Warrant will vest and become fully exercisable as to an 
additional 20% of the Shares upon the attainment by the Company in any fiscal 
year after the consummation by the Company of its acquisition of all the 
outstanding shares of the capital stock of Telereunion of earnings (before 
depreciation, amortization and non-cash charges against the earnings of the 
Company arising as a result of the vesting of this Warrant and the other 
similar warrants issued in connection with the acquisition of the outstanding 
capital stock of Telereunion) per share of $0.75, computed in accordance with 
generally accepted accounting principles, PROVIDED that 2,500,000 of the 
Total Warrant Shares will be included in the calculation of the earnings per 
share of the Company in all instances regardless of whether the closing price 
for a share of Common Stock quoted on the NASDAQ on the date on which such 
calculation is made is more or less than the Exercise Price; and PROVIDED 
that the percentage of the Shares as to which this Warrant will vest and 
become fully exercisable pursuant to this clause (ii) will be increased to 
100% of the Shares if there has been no vesting of the Warrant and the right 
to exercise this Warrant pursuant to the immediately preceding clause (ii).

     (iv) Notwithstanding the foregoing, this Warrant will vest and become 
fully exercisable as to any of the Total Warrant Shares not already vested 
and exercisable if the closing price for a share of Common Stock quoted on 
The Nasdaq Stock Market or other reliable public market (e.g., either the New 
York Stock Exchange or the American Stock Exchange) equals or exceeds $12.00 
for any ninety (90) consecutive trading days.

     2.   TRANSFER AND EXCHANGE.  This Warrant and all options and rights under
this Warrant are transferable, as to all or any part of the number of Shares 
issuable under the terms of this Warrant, by the holder of this Warrant, in 
person or by duly authorized attorney, on the books of the Company upon 
surrender of the Warrant at the principal offices of the Company, together 
with the attached, properly endorsed, Assignment Form. Absent any such transfer,
the Company may deem and treat the registered holder of this Warrant at any time
as the absolute owner of the Warrant for all purposes and will not be affected 
by any notice to the contrary.  If this Warrant is transferred in part, the 
Company will, at the time of surrender, issue to the transferee a Warrant 
covering the number of issuable Shares transferred and to the transferor a 
Warrant covering the number of issuable Shares not transferred.

     3.   EXERCISE.

          (a) This Warrant may be exercised as to all or any of the Shares as 
     to which this Warrant has vested and become fully exercisable at any time
     or from time to time on or after the date on which such vesting of the 
     Warrant occurs as to such Shares, on any Business Day (as defined in 
     Section 9 below).  In order to exercise this Warrant, in whole or in part,
     the holder will deliver to the Company at its principal offices (i) a 
     written notice of such holder's election to exercise its Warrant, 
     substantially in the form of the Warrant Exercise Notice attached to this
     Warrant, (ii) payment of the Exercise Price, in an amount equal to the 
     aggregate purchase price for all Shares to be purchased pursuant to such 
     exercise, and (iii) the Warrant.  Upon receipt of such notice, the Company
     will, as promptly as practicable, and in any event within ten (10) Business
     Days, execute, or cause to be executed, and deliver to such holder a 
     certificate or certificates representing the aggregate number of full 
     shares of Common Stock issuable upon such exercise.  The stock certificate
     or certificates so delivered will be in such denominations as may be 
     specified in such notice and will be registered in the name of such holder,
     or such other name as designated in such notice.  A Warrant will be deemed
     to have been exercised, such certificate or certificates will be deemed to
     have been issued, and such holder or any other person or entity so 
     designated or named in such notice will be deemed to have become a holder 
     of record of such shares for all purposes, as of the date that such notice
     (together with payment of the Exercise Price and the Warrant) is received 
     by the Company.  If the Warrant has been exercised in part, the Company 
     will, at the time of delivery of such certificate of certificates, either
     deliver to such holder a new Warrant evidencing the rights of such holder
     to purchase a number of Shares with respect to which the Warrant has not 
     been exercised, which new Warrant will, in all other respects, be identical
     to this Warrant, or, at the request of such holder, appropriate notation 
     may be made on the Warrant and the Warrant returned to such holder.

          (b)  Payment of the Exercise Price will be made, at the option of the
     holder, by (i) company or individual check (subject to collection), 
     certified or official bank check or (ii) cancellation of any debt owed by 
     the Company to the holder.  If the holder surrenders a combination of cash
     or cancellation of any debt owed by the Company to the holder, the holder 
     will specify the respective number of shares of Common Stock to be 
     purchased with each form of consideration, and the foregoing provisions 
     will be applied to each form of consideration with the same effect as if 
     the Warrant were being separately exercised with respect to each 



                                      3


<PAGE>

     form of consideration; PROVIDED, HOWEVER, that a holder may designate that
     any cash to be remitted to a holder in payment of debt be applied, together
     with other monies, to the exercise of the portion of the Warrant being 
     exercised for cash.

          (c) In lieu of exercising this Warrant in the manner set forth in 
     paragraph 3(b) above, this Warrant may be exercised by surrender of the 
     Warrant without payment of any other consideration, commission or 
     remuneration, together with the cashless exercise subscription form at the
     end hereof, duly executed.  The number of shares to be issued in exchange 
     for the Warrant shall be the product of (x) the excess of the Market Price
     (as defined below) of the Common Stock on the date of surrender of the 
     Warrant and the exercise subscription form OVER the Exercise Price per 
     share and (y) the number of shares subject to issuance upon exercise of 
     the Warrant, divided by the Market Price of the Common Stock on such date.
     Upon such exercise and surrender of this Warrant, the Company will (i) 
     issue a certificate or certificates in the name of the holder for the 
     largest number of whole shares of the Common Stock to which the holder 
     shall be entitled and, in lieu of any fractional share of the Common Stock
     to which the Holder shall be entitled, pay cash equal to the fair value of
     such fractional share (determined in such reasonable manner as the Board 
     of Directors of the Company shall determine), and (ii) deliver the other
     securities and properties receivable upon the exercise of this Warrant, 
     pursuant to the provisions of this Warrant.

          (d) The market price of a share of the Common Stock (the "Market 
     Price") on any date of determination shall be (i) the average of the last
     reported sale price of the Common Stock on the five business days 
     immediately preceding the date of determination as reported on the Nasdaq 
     Market ("NASDAQ") or (ii) if there is no such reported sale on any of the
     dates in question, the average of the closing bid and asked quotations as
     so reported on NASDAQ for such dates.

     4.   NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip 
representing fractional shares will be issued upon the exercise of this Warrant.
In lieu of any fractional share to which a holder would otherwise be entitled,
such holder will be entitled to receive, at its option, either (i) a cash 
payment equal to the excess of fair market value for such fractional share 
above the Exercise Price for such fractional share (as mutually determined by
the Company and the holder) or (ii) a whole share if the holder tenders the 
Exercise Price for one whole share.

     5.   CHARGES, TAXES AND EXPENSES.  Issuance of certificates for shares 
upon the exercise of this Warrant will be made without charge to the holder 
for any issue or transfer tax or other incidental expense in respect of the 
issuance of such certificates, all of which taxes and expenses will be paid 
by the Company.

     6.   NO RIGHTS AS SHAREHOLDERS.  This Warrant does not entitle the holder
to any voting rights, dividend rights or other rights as a shareholder of the 
Company prior to exercise.

     7.   WARRANT REGISTER.  The Company will, at all times while this Warrant
remains outstanding and exercisable, keep and maintain at its principal office
a register in which the registration,



                                      4

<PAGE>

transfer, and exchange of the Warrants will be provided for.  The Company will 
not at any time, except upon the dissolution, liquidation, or winding up of the
Company, close such register so as to result in preventing or delaying the 
exercise or transfer of any Warrant.


     8.   LOST, STOLEN, MUTILATED, OR DESTROYED WARRANT.  If this Warrant is 
lost, stolen, mutilated, or destroyed, the Company will issue a new Warrant 
of like denomination, tenor, and date upon receipt of and appropriate affidavit
and indemnity executed by the Holder.  Any such new Warrant will constitute an
original contractual obligation of the Company, whether or not the allegedly 
lost, stolen, mutilated, or destroyed Warrant is at any time enforceable by 
any person or entity.

     9.   BUSINESS DAYS.  A "Business Day" is any day other than Saturday, 
Sunday, or legal holiday.  If the last or appointed day for the taking of any 
action or the expiration of any right required or granted in this Warrant is 
not a Business Day, then such action may be taken or such right may be 
exercised on the following Business Day.

     10.   ADJUSTMENTS.

     (a)  ADJUSTMENT EVENTS.  The Warrant will be exercisable for the number 
of shares of Common Stock in such manner that, following the complete and full
exercise of this Warrant, the amount of Common Stock and other property issued
to the holder of this Warrant will equal the aggregate number of shares of 
Common Stock set forth in Section 1(a), as adjusted, to the extent necessary,
to give effect to the following events:

                 (i) (A) The holder of this Warrant will be entitled to an 
          adjustment as set forth in Section 10(a)(i)(B), if at any time or 
          from time to time, the holders of any class of Common Stock or any 
          option, warrant, right, or similar security exercisable into or 
          exchangeable for Common Stock ("Common Stock Equivalent") have 
          received, or (on or after the record date fixed for the determination
          of shareholders eligible to receive) have become entitled to receive,
          without payment therefor, (I) property (other than cash) by way of 
          dividend or distribution; or (II) property (including cash) by way of
          spin-off, split-up, reclassification (including any reclassification
          in connection with a consolidation or merger in which the Company is
          the surviving corporation), recapitalization, combination of shares 
          into a smaller number of shares, or similar corporate restructuring.

                     (B) In each such case, the holder of this Warrant will be
          entitled to receive for each share of Common Stock issuable under 
          this Warrant as of the record date fixed for such distribution, the
          greatest per share amount of property received or receivable by any
          holder of any class of Common Stock or Common Stock Equivalent.  With
          respect to any subsequent distribution, all such consideration 
          receivable pursuant to this Section 10(a)(i) will be deemed 
          outstanding and owned by the holder when determining the amount of 
          consideration due to the holder upon exercise of the Warrant.

<PAGE>

                     (C) This Section 10(a)(i) does not apply to additional 
          shares of Common Stock issued as a stock dividend or in a stock-split.

                 (ii) If at any time there occurs any stock split, stock 
          dividend, reverse stock split, or other subdivision of the Common 
          Stock, then the number of shares of Common Stock to be received and 
          the Exercise Price to be paid will be proportionately adjusted.

                 (iii) (A) The following events will constitute "Reorganization
          Events": (I) any reclassification or change of outstanding shares of
          any class of Common Stock or Common Stock Equivalent (other than a 
          change in par value, or from par value to no par value, or from no 
          par value to par value), or (II) any consolidation of the Company 
          with, or merger or share exchange of the Company with or into, 
          another entity, or (III) any sale of all or substantially all of the
          property, assets, business, income or revenue generating capacity, 
          or goodwill of the Company.

                       (B) Upon the occurrence of a Reorganization Event, the 
          Company, or the successor or other entity, as the case may be, will 
          provide that the holder of this Warrant will receive the highest per
          share kind and amount of consideration (including cash) received or 
          receivable upon such Reorganization Event by any holder of any class
          of Common Stock or Common Stock Equivalent for each Share issuable 
          under this Warrant immediately prior to such Reorganization Event (as
          adjusted pursuant to Section 10(a)(i)).  Any such successor entity, 
          which thereafter will be deemed to be the Company for purposes of this
          Warrant, will provide for adjustments that are as nearly equivalent
          as may be possible to the adjustments provided for by this Section 10.

                 (v) In case any event occurs as to which the preceding Sections
          10(a)(i) through (iii) are not strictly applicable, but as to which 
          the failure to make any adjustment would not fairly protect the 
          purchase rights represented by the Warrants in accordance with the 
          essential intent and principles of this Section 10, then, in each such
          case, the holder and the Company will negotiate for 30 days in good 
          faith in an attempt to reach a mutually agreeable solution.  If, at 
          the end of such 30-day period the Company and the holder have not 
          reached such an agreement, the holder may appoint an independent 
          investment bank or firm of independent public accountants reasonably
          acceptable to the Company, which will give its opinion as to the 
          adjustment, if any, on a basis consistent with the essential intent
          and principles established in this Section 10, necessary to preserve
          the purchase rights represented by this Warrant.  Upon receipt of such
          opinion, the Company will promptly deliver a copy of such opinion to 
          the holder and will make the adjustments described in such opinion. 
          The fees and expenses of such investment bank or independent public 
          accountants will be borne equally by the Company and the holder.

          (b)  ROUNDING.  Any calculation under this Section 10 will be made to
the nearest one ten-thousandth of a share and the number of issuable Shares 
resulting from such



                                      6


<PAGE>

calculation will be rounded up to the next whole share of Common Stock 
comprising issuable Shares.

          (c)    NOTICE OF EVENTS.

                 (i) In the event of (A) any setting by the Company of a record
          date with respect to the holders of any class of the capital stock of
          the Company for the purpose of determining which of such holders are
          entitled to dividends, repurchases of securities or other 
          distributions, or any right to subscribe for, purchase or otherwise 
          acquire any shares of such capital stock or other property or to 
          receive any other right; or (B) any capital reorganization of the 
          Company, or reclassification or recapitalization of the capital stock
          of the Company or any transfer of all or a majority of the assets, 
          business, or revenue or income generating capacity of the Company, or
          consolidation, merger, share exchange, reorganization, or similar 
          transaction involving the Company; or (C) any voluntary or involuntary
          dissolution, liquidation, or winding up of the Company; or (D) any 
          proposed issue or grant by the Company of any capital stock of the 
          Company, or any right or option to subscribe for, purchase, or 
          otherwise acquire any capital stock of the Company (other than the 
          issue of Issuable Warrant Shares upon exercise of this Warrant), then,
          in each such event, the Company will deliver or cause to be delivered
          to the holders a notice specifying, as the case may be, (I) the date 
          on which any such record is to be set for the purpose of such 
          dividend, distribution, or right, and stating the amount and character
          of such dividend, distribution, or right; (II) the date as of which 
          the holders of record will be entitled to vote on any reorganization,
          reclassification, recapitalization, transfer, consolidation, merger, 
          share exchange, conveyance, dissolution, liquidation, or winding-up;
          (III) the date on which any such reorganization, reclassification, 
          recapitalization, transfer, consolidation, merger, share exchange, 
          conveyance, dissolution, liquidation, or winding-up is to take place 
          and the time, if any is to be fixed, as of which the holders of record
          of any class of capital stock of the Company will be entitled to 
          exchange their shares of capital stock for securities or other 
          property deliverable upon such event; (IV) the amount and character 
          of any capital stock, property, or rights proposed to be issued or 
          granted, the consideration to be received therefor, and, in the case
          of rights or options, the exercise price thereof, and the date of 
          such proposed issue or grant and the persons or class of persons to 
          whom such proposed issue or grant will be offered or made; and (V) 
          such other information as the holders may reasonably request.  Any
          such notice will be deposited in the United States mail, postage 
          prepaid, at least thirty (30) days prior to the date therein 
          specified, and notwithstanding anything in this Agreement or this 
          Warrant to the contrary the holders may exercise this Warrant within
          thirty (30) days from the receipt of such notice.

                 (ii) If there is any adjustment as provided above in Section 
          10(a), the Company will immediately cause written notice thereof to 
          be sent to the holder, which notice will be accompanied by a 
          certificate of the independent public accountants of the Company 
          setting forth in reasonable detail the facts requiring any such 
          adjustment in the number of shares receivable after such adjustment.
          At the request of the holder and 



                                      7


<PAGE>

          upon surrender of this Warrant of such holder, the Company will 
          reissue this Warrant of such holder in a form conforming to such 
          adjustments.

     11.  ASSURANCES. The Company will not by any action including, without 
limitation, amending, or permitting the amendment of, the charter documents, 
bylaws, or similar instruments of the Company or through any reorganization, 
reclassification, transfer of assets, consolidation, merger, share exchange, 
dissolution, issue or sale of securities, or any other similar voluntary 
action, avoid or seek to avoid the observance or performance of any of the 
terms of this Warrant, but will at all times in good faith assist in the 
carrying out of all such terms and in the taking of all such actions as may be
necessary or appropriate to protect the rights of the holder against impairment
or dilution.  Without limiting the generality of the foregoing, the Company 
will, with respect to this Warrant, (i) take all such action as may be 
necessary or appropriate in order that the Company may validly and legally 
issue fully paid and nonassessable shares of Common Stock, free and clear of 
all liens, encumbrances, equities, and claims and (ii) use its best efforts to
obtain all such authorizations, exemptions, or consents from any public 
regulatory body having jurisdiction as may be necessary to enable the Company
to perform its obligations under this Warrant.

     12.  MISCELLANEOUS.

          (a)  EMPLOYMENT OF HOLDER.  The parties hereto acknowledge and 
agree that the issuance, vesting and exercise of this Warrant is in no way 
tied to, or conditioned upon, the employment by the Company or any affiliate

related to the holder hereof.

          (b)  SUCCESSORS.  This Warrant will be binding upon any successors or
assigns of the Company.

          (C)  GOVERNING LAW.  THIS WARRANT WILL CONSTITUTE A CONTRACT UNDER 
THE LAWS OF TEXAS AND FOR ALL PURPOSES WILL BE CONSTRUED IN ACCORDANCE WITH 
AND GOVERNED BY THE LAWS OF SAID STATE, WITHOUT GIVING EFFECT TO THE CONFLICT 
OF LAWS PRINCIPLES OR ANY OTHER PRINCIPLE THAT COULD REQUIRE THE APPLICATION 
OF THE LAWS OF ANY OTHER JURISDICTION.

          (d)  ATTORNEY'S FEES.  In any litigation, arbitration or court 
proceeding between the Company and the holder relating hereto, the prevailing 
party will be entitled to reasonable attorneys' fees and expenses incurred in 
enforcing this Warrant.

          (f)  NOTICE.  Any notice required or permitted under this Warrant 
will be deemed effectively given upon personal delivery to the party to be 
notified or upon deposit with the United States Post Office, by certified mail,

     BY AND AMONG POLISH TELEPHONES AND MICROWAVE CORPORATION, 
     PTMC ACQUISITION SUB, INC., TELEREUNION, INC. AND CERTAIN OF
     STOCKHOLDERS OF TELEREUNION, INC. (AS SUCH AGREEMENT MAY BE
     SUPPLEMENTED, MODIFIED, AMENDED, OR RESTATED FROM TIME TO TIME,
     THE "AGREEMENT").  COPIES OF THE AGREEMENT IS AVAILABLE AT THE 
     OFFICES OF POLISH TELEPHONES AND MICROWAVE CORPORATION.


         WARRANT TO PURCHASE SHARES OF COMMON STOCK, $0.001 PAR VALUE
          PER SHARE, OF POLISH TELEPHONES AND MICROWAVE CORPORATION


     THIS CERTIFIES that, for value received, _____________________________ 
(the "Warrantholder"), is entitled, upon the terms and subject to the conditions
hereinafter set forth, to purchase from Polish Telephones and Microwave 
Corporation, a Texas corporation (the "Company"), that number of fully paid and
nonassessable shares of the Company's common stock, $0.001 par value per share
(the "Common Stock"), at the purchase price per share (the "Exercise Price") as
set forth in Section 1 below.  The number of shares and Exercise Price are 
subject to adjustment as provided in Section 10 below.

     1.   NUMBER OF SHARES; EXERCISE PRICE; TERM.

          (a) This Warrant is exercisable for _____________ shares (the 
"Shares") of Common Stock at a purchase price of $2.19 per share (the "Exercise
Price").

          (b) Subject to the terms and conditions set forth in this Warrant, 
this Warrant will be exercisable (i) upon the attainment by the Company of an 
increase in net shareholders equity of the Company of at least $5,000,000 
computed by comparing (A) the net shareholders equity of the Company on a pro 
forma basis after giving effect to the acquisition of Telereunion, Inc., a 
Delaware corporation ("Telereunion") by the Company as of the date of the 
consummation of such acquisition to (B) the net shareholders equity of the 
Company as set forth in a consolidated balance sheet of the Company as of any 
date occurring during the 18-month period immediately following the 
consummation of the acquisition of Telereunion by the Company,



                                     1


<PAGE>

which balance sheet shall be contained in any periodic report of the Company 
on Form 10-KSB or Form 10-QSB as filed with the Securities and Exchange 
Commission or (ii) if the closing price for a share of Common Stock quoted on 
The NASDAQ Stock Market or other reliable public market (e.g., either the New 
York Stock Exchange or the American Stock Exchange) equals or exceeds $12.00 
for any ninety (90) consecutive trading days.  If the condition for vesting 
is not satisfied within the 18 month period immediately following the 
consummation of the acquisition of Telereunion by the Company, this Warrant 
will expire and no longer be exercisable. In any event, this Warrant  will 
expire on and no longer be exercisable after May ___, 2003.

     2.   TRANSFER AND EXCHANGE.  This Warrant and all options and rights 
under this Warrant are transferable, as to all or any part of the number of 
Shares issuable under the terms of this Warrant, by the holder of this 
Warrant, in person or by duly authorized attorney, on the books of the 
Company upon surrender of the Warrant at the principal offices of the 
Company, together with the attached, properly endorsed, Assignment Form.  
Absent any such transfer, the Company may deem and treat the registered 
holder of this Warrant at any time as the absolute owner of the Warrant for 
all purposes and will not be affected by any notice to the contrary.  If this 
Warrant is transferred in part, the Company will, at the time of surrender, 
issue to the transferee a Warrant covering the number of issuable Shares 
transferred and to the transferor a Warrant covering the number of issuable 
Shares not transferred.

     3.   EXERCISE.

          (a) This Warrant may be exercised as to all or any of the Shares as 
     to which this Warrant has vested and become fully exercisable at any time
     or from time to time on or after the date on which such vesting of the 
     Warrant occurs as to such Shares, on any Business Day (as defined in 
     Section 9 below).  In order to exercise this Warrant, in whole or in part,
     the holder will deliver to the Company at its principal offices (i) a 
     written notice of such holder's election to exercise its Warrant, 
     substantially in the form of the Warrant Exercise Notice attached to this
     Warrant, (ii) payment of the Exercise Price, in an amount equal to the 
     aggregate purchase price for all Shares to be purchased pursuant to such 
     exercise, and (iii) the Warrant.  Upon receipt of such notice, the Company
     will, as promptly as practicable, and in any event within ten (10) Business
     Days, execute, or cause to be executed, and deliver to such holder a 
     certificate or certificates representing the aggregate number of full 
     shares of Common Stock issuable upon such exercise.  The stock certificate
     or certificates so delivered will be in such denominations as may be 
     specified in such notice and will be registered in the name of such holder,
     or such other name as designated in such notice.  A Warrant will be deemed
     to have been exercised, such certificate or certificates will be deemed to
     have been issued, and such holder or any other person or entity so 
     designated or named in such notice will be deemed to have become a holder
     of record of such shares for all purposes, as of the date that such notice
     (together with payment of the Exercise Price and the Warrant) is received 
     by the Company.  If the Warrant has been exercised in part, the Company 
     will, at the time of delivery of such certificate of certificates, either
     deliver to such holder a new Warrant evidencing the rights of such holder 
     to purchase a number of Shares with respect to which the Warrant has not 
     been exercised, which new Warrant will, in all other respects, be identical
     to this Warrant, or, at the request of such holder, appropriate notation 
     may be made on the Warrant and the Warrant returned to such holder.



                                      2


<PAGE>

          (b) Payment of the Exercise Price will be made, at the option of the
     holder, by (i) company or individual check (subject to collection), 
     certified or official bank check or (ii) cancellation of any debt owed by
     the Company to the holder.  If the holder surrenders a combination of cash
     or cancellation of any debt owed by the Company to the holder, the holder
     will specify the respective number of shares of Common Stock to be 
     purchased with each form of consideration, and the foregoing provisions 
     will be applied to each form of consideration with the same effect as if
     the Warrant were being separately exercised with respect to each form of
     consideration; PROVIDED, HOWEVER, that a holder may designate that any 
     cash to be remitted to a holder in payment of debt be applied, together
     with other monies, to the exercise of the portion of the Warrant being 
     exercised for cash.

          (c) In lieu of exercising this Warrant in the manner set forth in 
     paragraph 3(b) above, this Warrant may be exercised by surrender of the 
     Warrant without payment of any other consideration, commission or 
     remuneration, together with the cashless exercise subscription form at the
     end hereof, duly executed.  The number of shares to be issued in exchange
     for the Warrant shall be the product of (x) the excess of the Market Price
     (as defined below) of the Common Stock on the date of surrender of the 
     Warrant and the exercise subscription form OVER the Exercise Price per 
     share and (y) the number of shares subject to issuance upon exercise of 
     the Warrant, divided by the Market Price of the Common Stock on such date.
     Upon such exercise and surrender of this Warrant, the Company will (i) 
     issue a certificate or certificates in the name of the holder for the 
     largest number of whole shares of the Common Stock to which the holder 
     shall be entitled and, in lieu of any fractional share of the Common 
     Stock to which the Holder shall be entitled, pay cash equal to the fair 
     value of such fractional share (determined in such reasonable manner as 
     the Board of Directors of the Company shall determine), and (ii) deliver 
     the other securities and properties receivable upon the exercise of this
     Warrant, pursuant to the provisions of this Warrant.

          (d) The market price of a share of the Common Stock (the "Market 
     Price") on any date of determination shall be (i) the average of the last
     reported sale price of the Common Stock on the five business days 
     immediately preceding the date of determination as reported on the Nasdaq
     Market ("NASDAQ") or (ii) if there is no such reported sale on any of the
     dates in question, the average of the closing bid and asked quotations as
     so reported on NASDAQ for such dates.

     4.   NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip 
representing fractional shares will be issued upon the exercise of this Warrant.
In lieu of any fractional share to which a holder would otherwise be entitled,
such holder will be entitled to receive, at its option, either (i) a cash 
payment equal to the excess of fair market value for such fractional share 
above the Exercise Price for such fractional share (as mutually determined by
the Company and the holder) or (ii) a whole share if the holder tenders the 
Exercise Price for one whole share.

     5.   CHARGES, TAXES AND EXPENSES.  Issuance of certificates for shares 
upon the exercise of this Warrant will be made without charge to the holder for
any issue or transfer tax or other 



                                      3


<PAGE>

incidental expense in respect of the issuance of such certificates, all of 
which taxes and expenses will be paid by the Company.

     6.   NO RIGHTS AS SHAREHOLDERS.  This Warrant does not entitle the holder 
to any voting rights, dividend rights or other rights as a shareholder of the 
Company prior to exercise.

     7.   WARRANT REGISTER.  The Company will, at all times while this Warrant
remains outstanding and exercisable, keep and maintain at its principal office
a register in which the registration, transfer, and exchange of the Warrants 
will be provided for.  The Company will not at any time, except upon the 
dissolution, liquidation, or winding up of the Company, close such register so 
as to result in preventing or delaying the exercise or transfer of any Warrant.

     8.   LOST, STOLEN, MUTILATED, OR DESTROYED WARRANT.  If this Warrant is 
lost, stolen, mutilated, or destroyed, the Company will issue a new Warrant 
of like denomination, tenor, and date upon receipt of and appropriate affidavit
and indemnity executed by the Holder.  Any such new Warrant will constitute an
original contractual obligation of the Company, whether or not the allegedly 
lost, stolen, mutilated, or destroyed Warrant is at any time enforceable by any
person or entity.

     9.   BUSINESS DAYS.  A "Business Day" is any day other than Saturday, 
Sunday, or legal holiday.  If the last or appointed day for the taking of any 
action or the expiration of any right required or granted in this Warrant is 
not a Business Day, then such action may be taken or such right may be exercised
on the following Business Day.

     10.  ADJUSTMENTS.

     (a)  ADJUSTMENT EVENTS.  The Warrant will be exercisable for the number 
of shares of Common Stock in such manner that, following the complete and full
exercise of this Warrant, the amount of Common Stock and other property issued
to the holder of this Warrant will equal the aggregate number of shares of 
Common Stock set forth in Section 1(a), as adjusted, to the extent necessary,
to give effect to the following events:

               (i)  (A) The holder of this Warrant will be entitled to an 
          adjustment as set forth in Section 10(a)(i)(B), if at any time or 
          from time to time, the holders of any class of Common Stock or any
          option, warrant, right, or similar security exercisable into or 
          exchangeable for Common Stock ("Common Stock Equivalent") have 
          received, or (on or after the record date fixed for the determination
          of shareholders eligible to receive) have become entitled to receive,
          without payment therefor, (I) property (other than cash) by way of 
          dividend or distribution; or (II) property (including cash) by way of
          spin-off, split-up, reclassification (including any reclassification
          in connection with a consolidation or merger in which the Company is
          the surviving corporation), recapitalization, combination of shares 
          into a smaller number of shares, or similar corporate restructuring.

                    (B) In each such case, the holder of this Warrant will be 
          entitled to receive for each share of Common Stock issuable under this
          Warrant as of



                                      4


<PAGE>

          the record date fixed for such distribution, the greatest per share
          amount of property received or receivable by any holder of any class
          of Common Stock or Common Stock Equivalent.  With respect to any 
          subsequent distribution, all such consideration receivable pursuant 
          to this Section 10(a)(i) will be deemed outstanding and owned by the
          holder when determining the amount of consideration due to the holder
          upon exercise of the Warrant.

                     (C) This Section 10(a)(i) does not apply to additional
          shares of Common Stock issued as a stock dividend or in a stock-split.

               (ii) If at any time there occurs any stock split, stock dividend,
          reverse stock split, or other subdivision of the Common Stock, then 
          the number of shares of Common Stock to be received and the Exercise
          Price to be paid will be proportionately adjusted.

               (iii) (A) The following events will constitute "Reorganization 
          Events": (I) any reclassification or change of outstanding shares of
          any class of Common Stock or Common Stock Equivalent (other than a 
          change in par value, or from par value to no par value, or from no 
          par value to par value), or (II) any consolidation of the Company 
          with, or merger or share exchange of the Company with or into, another
          entity, or (III) any sale of all or substantially all of the property,
          assets, business, income or revenue generating capacity, or goodwill 
          of the Company.

                     (B) Upon the occurrence of a Reorganization Event, the 
          Company, or the successor or other entity, as the case may be, will
          provide that the holder of this Warrant will receive the highest per
          share kind and amount of consideration (including cash) received or
          receivable upon such Reorganization Event by any holder of any class
          of Common Stock or Common Stock Equivalent for each Share issuable
          under this Warrant immediately prior to such Reorganization Event 
          (as adjusted pursuant to Section 10(a)(i)).  Any such successor 
          entity, which thereafter will be deemed to be the Company for purposes
          of this Warrant, will provide for adjustments that are as nearly 
          equivalent as may be possible to the adjustments provided for by this
          Section 10.

               (v) In case any event occurs as to which the preceding Sections
          10(a)(i) through (iii) are not strictly applicable, but as to which
          the failure to make any adjustment would not fairly protect the 
          purchase rights represented by the Warrants in accordance with the 
          essential intent and principles of this Section 10, then, in each 
          such case, the holder and the Company will negotiate for 30 days in 
          good faith in an attempt to reach a mutually agreeable solution.  If,
          at the end of such 30-day period the Company and the holder have not
          reached such an agreement, the holder may appoint an independent 
          investment bank or firm of independent public accountants reasonably
          acceptable to the Company, which will give its opinion as to the 
          adjustment, if any, on a basis consistent with the essential intent
          and principles established in this Section 10, necessary to preserve
          the purchase rights represented by this Warrant.  Upon receipt of 



                                      5


<PAGE>

          such opinion, the Company will promptly deliver a copy of such opinion
          to the holder and will make the adjustments described in such opinion.
          The fees and expenses of such investment bank or independent public 
          accountants will be borne equally by the Company and the holder.

          (b)  ROUNDING.  Any calculation under this Section 10 will be made 
to the nearest one ten-thousandth of a share and the number of issuable Shares
resulting from such calculation will be rounded up to the next whole share of 
Common Stock comprising issuable Shares.

          (c)  NOTICE OF EVENTS.

               (i) In the event of (A) any setting by the Company of a record
          date with respect to the holders of any class of the capital stock 
          of the Company for the purpose of determining which of such holders
          are entitled to dividends, repurchases of securities or other 
          distributions, or any right to subscribe for, purchase or otherwise
          acquire any shares of such capital stock or other property or to 
          receive any other right; or (B) any capital reorganization of the 
          Company, or reclassification or recapitalization of the capital stock
          of the Company or any transfer of all or a majority of the assets, 
          business, or revenue or income generating capacity of the Company, or
          consolidation, merger, share exchange, reorganization, or similar 
          transaction involving the Company; or (C) any voluntary or involuntary
          dissolution, liquidation, or winding up of the Company; or (D) any 
          proposed issue or grant by the Company of any capital stock of the 
          Company, or any right or option to subscribe for, purchase, or 
          otherwise acquire any capital stock of the Company (other than the 
          issue of Issuable Warrant Shares upon exercise of this Warrant), 
          then, in each such event, the Company will deliver or cause to be 
          delivered to the holders a notice specifying, as the case may be, 
          (I) the date on which any such record is to be set for the purpose of
          such dividend, distribution, or right, and stating the amount and 
          character of such dividend, distribution, or right; (II) the date as
          of which the holders of record will be entitled to vote on any 
          reorganization, reclassification, recapitalization, transfer, 
          consolidation, merger, share exchange, conveyance, dissolution, 
          liquidation, or winding-up; (III) the date on which any such 
          reorganization, reclassification, recapitalization, transfer, 
          consolidation, merger, share exchange, conveyance, dissolution, 
          liquidation, or winding-up is to take place and the time, if any is
          to be fixed, as of which the holders of record of any class of capital
          stock of the Company will be entitled to exchange their shares of 
          capital stock for securities or other property deliverable upon such
          event; (IV) the amount and character of any capital stock, property,
          or rights proposed to be issued or granted, the consideration to be 
          received therefor, and, in the case of rights or options, the exercise
          price thereof, and the date of such proposed issue or grant and the 
          persons or class of persons to whom such proposed issue or grant will
          be offered or made; and (V) such other information as the holders may
          reasonably request.  Any such notice will be deposited in the United 
          States mail, postage prepaid, at least thirty (30) days prior to the
          date therein specified, and notwithstanding anything in this Agreement
          or this Warrant to 



                                      6


<PAGE>

          the contrary the holders may exercise this Warrant within thirty (30)
          days from the receipt of such notice.

               (ii) If there is any adjustment as provided above in Section 
          10(a), the Company will immediately cause written notice thereof to 
          be sent to the holder, which notice will be accompanied by a 
          certificate of the independent public accountants of the Company 
          setting forth in reasonable detail the facts requiring any such 
          adjustment in the number of shares receivable after such adjustment.
          At the request of the holder and upon surrender of this Warrant of 
          such holder, the Company will reissue this Warrant of such holder in
          a form conforming to such adjustments.

     11.  ASSURANCES. The Company will not by any action including, without 
limitation, amending, or permitting the amendment of, the charter documents, 
bylaws, or similar instruments of the Company or through any reorganization, 
reclassification, transfer of assets, consolidation, merger, share exchange, 
dissolution, issue or sale of securities, or any other similar voluntary 
action, avoid or seek to avoid the observance or performance of any of the 
terms of this Warrant, but will at all times in good faith assist in the 
carrying out of all such terms and in the taking of all such actions as may 
be necessary or appropriate to protect the rights of the holder against 
impairment or dilution.  Without limiting the generality of the foregoing, 
the Company will, with respect to this Warrant, (i) take all such action as 
may be necessary or appropriate in order that the Company may validly and 
legally issue fully paid and nonassessable shares of Common Stock, free and 
clear of all liens, encumbrances, equities, and claims and (ii) use its best 
efforts to obtain all such authorizations, exemptions, or consents from any 
public regulatory body having jurisdiction as may be necessary to enable the 
Company to perform its obligations under this Warrant.

     12.  MISCELLANEOUS.

          (a)  EMPLOYMENT OF HOLDER.  The parties hereto acknowledge and agree
that the issuance, vesting and exercise of this Warrant is in no way tied to 
or conditioned upon the employment by the Company or any affiliate of the 
Company of the holder hereof or any person affiliated with or related to the
holder hereof.

          (b)  SUCCESSORS.  This Warrant will be binding upon any successors or
assigns of the Company.

          (C)  GOVERNING LAW.  THIS WARRANT WILL CONSTITUTE A CONTRACT UNDER 
THE LAWS OF TEXAS AND FOR ALL PURPOSES WILL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF SAID STATE, WITHOUT GIVING EFFECT TO THE CONFLICT OF 
LAWS PRINCIPLES OR ANY OTHER PRINCIPLE THAT COULD REQUIRE THE APPLICATION OF 
THE LAWS OF ANY OTHER JURISDICTION.

proceeding between the Company and the holder relating hereto, the prevailing 
party will be entitled to reasonable attorneys' fees and expenses incurred in

                            EMPLOYMENT AGREEMENT

     AGREEMENT, executed on this ___ day of April, 1996 and effective as of 
January 1, 1996 between TeleReunion, Inc., a Delaware corporation (the 
"Company"), and ______________, an individual resident of Mexico, D.F. (the 
"Employee").

                       W I T N E S S E T H:

     WHEREAS, the Employee is a highly valued and trusted employee of the 
Company's subsidiary, Vextro de Mexico S.A. de C.V. ("Vextro"); and

     WHEREAS, the Company desires to offer the Employee continued employment 
upon the terms and conditions set forth herein and the Employee desires to 
accept such employment; and

     NOW THEREFORE in consideration of the mutual benefits to be derived from 
this Agreement, the Company and the Employee hereby agree as follows:

1.   TERM OF EMPLOYMENT; OFFICE AND DUTIES.

          (a)  During the Period of Employment (as hereinafter defined), the 
Company, through Vextro or one or more of its other subsidiaries, shall 
employ the Employee as a senior executive of the Company with the titles of 
Vice President, with the duties and responsibilities prescribed for such 
offices in the Bylaws of the Company and such subsidiaries, and with such 
additional duties and responsibilities consistent with such positions as may 
from time to time be assigned to the Employee by the Board of Directors of 
the Company (the "Board of Directors"). Employee agrees to perform such 
duties and discharge such responsibilities in accordance with the terms of 
this Agreement.

          (b)  During the Period of Employment, the Employee shall devote 
substantially all of his working time and attention to the business and 
affairs of the Company and its subsidiaries, other than during vacations 
(which shall be of a duration that is consistent with the policies of the 
Company) and periods of illness or incapacity; provided, however, that 
nothing in this Agreement shall preclude the Employee from devoting time 
required:  (i) for serving as a director or officer of any organization or 
entity involving no conflict of interest with the Company; (ii) delivering 
lectures, fulfilling speaking engagements or participating in activities of 
professional associations including chambers of commerce; and (iii) engaging 
in charitable and community activities; PROVIDED THAT, such activities do not 
interfere with the performance of his duties hereunder and devoting 
substantially all of his working time and attention to the business affairs 
of the Company, its subsidiaries, and the Company's Parent.

2.   TERM; PERIOD OF EMPLOYMENT

     The period of employment hereunder (the "Period of Employment") shall 
commence on the date hereof (the "Effective Date") and, unless sooner 
terminated pursuant to this Agreement, 


<PAGE>

shall terminate on the third anniversary of the Effective Date.  The Period 
of Employment may be extended by the written agreement of the Company and 
Employee.

3.   COMPENSATION AND BENEFITS.

     For all services rendered by the Employee in any capacity during the 
Period of Employment, including without limitation, services as an executive 
officer, director, or member of any committee of the Company or any 
subsidiary, affiliate or division thereof, the Employee shall be compensated 
as follows:

          (a)  BASE SALARY.  The Company shall pay the Employee a fixed 
salary ("Base Salary") at a rate of Eighty Thousand Dollars (US $80,000) per 
year.  The Board of Directors will periodically review, at least annually, 
the Employee's Base Salary with a view to increasing such Base Salary if, in 
the judgment of the Board of Directors, the earnings of the Company or the 
services of the Employee merit such an increase.  Annual increases in Base 
Salary, once granted, shall not be subject to revocation and shall become a 
part of the Base Salary.  Base Salary will be payable in accordance with the 
customary payroll practices of the Company, but in no event less frequently 
than monthly.

          (b)  BONUS.  The Company may pay the Employee a bonus if, in the 
judgment of the Board of Directors, the earnings of the Company or the 
services of the Employee merit such bonus. 

          (c)  FRINGE BENEFITS.  During the Period of Employment, the 
Employee shall be entitled to participate in such fringe benefit, insurance, 
deferred compensation and stock option plans or programs of the Company, if 
any, to the extent that his position, tenure, salary, age, health and other 
qualifications make him eligible to participate, subject to the rules and 
regulations applicable thereto.  Such additional benefits shall include, but 
not be limited to, paid sick leave and individual health insurance, all in 
accordance with the policies of the Company.  Except as specifically set 
forth herein, the terms of, and participation by the Employee in, any such 
plan or program shall be determined by the Board of Directors in its sole 
discretion.  In the event of the Employee's disability, the Employee and his 
family shall continue to be covered by all of the Company's life, medical, 
health and dental plans, at the Company's expense, for lesser of the term of 
such disability or the remaining term of the Period of Employment.  In the 
event of the Employee's death, the Employee's family shall continue to be 
covered by all of the Company's medical, health and dental plans, at the 
Company's expense, for twenty-four (24) months following the Employee's death.

          (d)  WITHHOLDING AND EMPLOYMENT TAX.  Payment of all compensation 
hereunder shall be subject to customary withholding tax and other employment 
taxes and deductions as may be required with respect to compensation paid by 
an employer/corporation to an employee.


                                      2

<PAGE>

          (e)  VACATIONS.  Employee shall be entitled to annual vacations of 
two weeks in accordance with the policies of the Company or, if more 
generous, as required by the laws of Mexico.

4.   BUSINESS EXPENSES.

     The Company shall pay or reimburse the Employee for all reasonable 
travel or other expenses incurred by the Employee in connection with the 
performance of his duties under this Agreement, including reimbursement for 
attending meetings of the Board of Directors, in accordance with such 
procedures as the Company may from time to time establish for senior officers 
and as required to preserve any deductions for income taxation purposes to 
which the Company may be entitled.

5.   TERMINATION OF EMPLOYMENT.

     Notwithstanding any other provision of this Agreement, the Period of 
Employment may be terminated:

          (a)  By the Company, in the event of the Employee's death, 
Disability (as hereinafter defined) or for Cause (as hereinafter defined).  
For purposes of this Agreement, "Cause" shall mean Employee's conviction of a 
crime involving an act or acts of dishonesty, fraud or moral turpitude by the 
Employee, which act or acts constitute a felony and the willful and continued 
failure to substantially perform Employee's duties hereunder after receipt of 
written notice from the Company specifically setting forth such failure.  For 
purposes of this Agreement, "Disability" shall mean the inability of 
Employee, in the reasonable judgment of a physician appointed by the Board of 
Directors, to perform his duties of employment for the Company or any of its 
subsidiaries because of any physical or mental disability or incapacity, 
where such disability shall exist for an aggregate period of more than 120 
days in any 365-day period or for any period of 90 consecutive days.  The 
Company shall by written notice to the Employee specify the event relied upon 
for termination pursuant to this Subsection 5(a), and the Period of 
Employment hereunder shall be deemed terminated as of the date of such 
notice.  In the event of any termination under this Subsection 5(a), the 
Company shall pay all amounts then due to the Employee under Section 3(a) of 
this Agreement, in addition to any severance payments required by law, and, 
if such termination was due to Cause, the Company shall have no further 
obligations to Employee under this Agreement.

          (b)  By the Company, for any reason and in its sole and absolute 
discretion, provided that in such event the Company shall, in addition to any 
severance payments required by law, as liquidated damages or severance pay, 
or both, continue to pay to the Employee the Base Salary for a period of one 
year.

          (c)  By the Employee, (i) if the Company's Board of Directors fails 
to elect or reelect the Employee to, or removes the Employee from, any of the 
offices referred to in Section 


                                      3

<PAGE>

1(a) or (ii) if the Employee is not elected or re-elected, or is removed from 
the Board of Directors of the Company other than for Cause or failure to 
discharge properly his duties in any such offices or at the direction of the 
Company.  In the event of any termination under this Section 5(c), the 
Company shall, in addition to any severance payments required by law, as 
liquidated damages or severance pay, or both, continue to pay to the Employee 
the Base Salary for a period of one year after such termination.

          (d)  During any period in which payments are payable by the Company 
to Employee pursuant to Sections 5(b) or 5(c) hereof (such payments being 
hereinafter collectively referred to as "Termination Payments"), Employee and 
his family shall continue to be covered by the Company's life, medical, 
health and death plans.  Such coverage shall be at the Company's expense to 
the same extent as if Employee were still employed by the Company.

6.   NON-COMPETITION.

     During the Period of Employment hereunder and for the one year period 
thereafter, the Employee shall not, anywhere within the United Mexican 
States, the United States of America or anywhere else in the world in which 
the Company (or any of its subsidiaries) is then doing business, engage in 
activities in competition with the business of the Company, including but not 
limited to any aspect of the teleconferencing or telecommunications 
businesses, whether as an individual, investor, partner, joint venturer, 
consultant, employee, agent, salesman, officer or director or otherwise.  In 
addition, for one year following the later of the last day of the Period of 
Employment or the payment of the last Termination Payment hereunder, the 
Employee shall not, within any jurisdiction in which the Company or any 
subsidiary of the Company is then doing business, or within a one hundred 
(100) mile radius of any such jurisdiction, engage in activities in 
competition with the business of the Company or any subsidiary, either as an 
individual, investor, partner, joint venturer, consultant, employee, agent, 
salesman, officer or director or otherwise.  Investments in less than five 
percent of the outstanding securities of any class of a publicly-traded 
company shall not be prohibited by this Section 6.

7.   INVENTIONS AND CONFIDENTIAL INFORMATION.

     The parties hereto recognize that a major need of the Company is to 
preserve its specialized knowledge, trade secrets, and confidential 
information.  The strength and good will of the Company is derived from the 
specialized knowledge, trade secrets, and confidential information generated 
from experience with the activities undertaken by the Company and its 
subsidiaries.  The disclosure of this information and knowledge to 
competitors would be beneficial to them and detrimental to the Company, as 
would the disclosure of information about the marketing practices, pricing 
practices, costs, profit margins, design specifications, analytical 
techniques, and similar items of the Company and its subsidiaries.  By reason 
of his being a senior executive of the Company, the Employee has or will have 
access to, and has obtained or will obtain, specialized knowledge, trade 
secrets and confidential information about the Company's operations and the 
operations of its subsidiaries, which operations extend throughout the United 


                                      4

<PAGE>

Mexican States.  Therefore, the Employee hereby agrees as follows, 
recognizing that the Company is relying on these agreements in entering into 
this Agreement:

   (i)    During and after the Period of Employment hereunder the 
          Employee will maintain as confidential and will not use, disclose 
          to others, or publish or otherwise make available to any other 
          party any inventions or any confidential business information about 
          the affairs of the Company and its subsidiaries, including but not 
          limited to confidential information concerning their products, 
          methods, product purchasing arrangements and agreements, product 
          distribution arrangements and agreements, engineering designs, 
          system designs and standards, analytical techniques, technical 
          information, customer information, employee information, and other 
          confidential information acquired by him in the course of his past 
          or future services for the Company.  Employee agrees to hold as the 
          Company's property all memoranda, books, papers, letters, formulas 
          and other data, and all copies thereof and therefrom, in any way 
          relating to the Company's or its subsidiaries' businesses and 
          affairs, whether made by him or otherwise coming into his 
          possession, and on termination of his employment, or on demand of 
          the Company, at any time, to deliver the same to the Company within 
          twenty four (24) hours of such termination or demand.

  (ii)    During the Period of Employment hereunder and for one year following 
          the last day of the Period of Employment, the Employee will not 
          induce or otherwise attempt to influence any employee of the 
          Company or its subsidiaries, to leave such entity's employ or hire 
          any such employee (unless the Board of Directors shall have 
          authorized such employment and the Company shall have consented 
          thereto in writing).

8.   INDEMNIFICATION.

     The Company will indemnify the Employee (and his legal representatives) 
to the fullest extent permitted by the laws of the state in which the Company 
is incorporated, as in effect at the time of the subject act or omission, or 
the Certificate of Incorporation and Bylaws of the Company, as in effect at 
such time or on the date of this Agreement, whichever affords greater 
protection to the Employee, and the Employee shall be entitled to the 
protection of any insurance policies the Company may elect to maintain 
generally for the benefit of its directors and officers, against all costs, 
charges and expenses whatsoever incurred or sustained by him or his legal 
representative in connection with any action, suit or proceeding to which he 
(or his legal representatives or other successors) may be made a party by 
reason of his being or having been a director or officer of the Company or 
any of its subsidiaries.

9.   LITIGATION EXPENSES.

     In the event of any litigation or other proceeding between the Company 
and the Employee with respect to the subject matter of this Agreement and the 
enforcement of the rights hereunder, the Company shall reimburse the Employee 
for all of his reasonable costs and expenses relating to such litigation or 
other proceeding, including, without limitation, his reasonable attorneys' 
fees and expenses, provided that such litigation or proceeding results in:

          (i)  settlement requiring the Company to make a payment to the 
               Employee, or

          (ii) final judgment or order in favor of the Employee.

10.  CONSOLIDATION; MERGER; SALE OF ASSETS; CHANGE OF CONTROL.

     Nothing in this Agreement shall preclude the Company from combining, 
consolidating or merging with or into, transferring all or substantially all 
of its assets to, or entering into a partnership or joint venture with, 
another corporation or other entity, or effecting any other kind of corporate 
combination provided that the corporation resulting from or surviving such 
combination, consolidation or merger, or to which such assets are 
transferred, or such partnership or joint venture assumes this Agreement and 
all obligations and undertakings of the Company hereunder.  Upon such a 
consolidation, merger, transfer of assets or formation of such partnership or 
joint venture, this Agreement shall inure to the benefit of, be assumed by, 
and be binding upon such resulting or surviving transferee corporation or 
such partnership or joint venture, and the term "Company," as used in this 
Agreement, shall mean such corporation, partnership or joint venture, or 
other entity and this Agreement shall continue in full force and effect and 
shall entitle the Employee and his heirs, beneficiaries and representatives 
to exactly the same compensation, benefits, perquisites, payments and other 
rights as would have been their entitlement had such combination, 
consolidation, merger, transfer of assets or formation of such partnership or 
joint venture not occurred.

11.  SURVIVAL OF OBLIGATIONS.

     Sections 5, 6, 7, 8, 9 and 10 shall survive the termination for any 
reason of this Agreement (whether such termination is by the Company, by the 
Employee, upon the expiration of this Agreement or otherwise).

12.  SEVERABILITY.

     In case any one or more of the provisions or part of a provision 
contained in this Agreement shall for any reason be held to be invalid, 
illegal or unenforceable in any respect in any jurisdiction, such invalidity, 
illegality or unenforceability shall be deemed not to affect any other 
jurisdiction or any other provision or part of a provision of this Agreement, 
nor shall such 


                                      6

<PAGE>

invalidity, illegality or unenforceability affect the validity, legality or 
enforceability of this Agreement or any provision or provisions hereof in any 
other jurisdiction; and this Agreement shall be reformed and construed in 
such jurisdiction as if such provision or part of a provision held to be 
invalid or illegal or unenforceable had never been contained herein and such 
provision or part reformed so that it would be valid, legal and enforceable 
in such jurisdiction to the maximum extent possible.  In furtherance and not 
in limitation of the foregoing, the Company and the Employee each intend that 
the covenants contained in Sections 6 and 7 shall be deemed to be a series of 
separate covenants, one for each state, territory or jurisdiction of the 
United Mexican States and the United States of America and any foreign 
country referenced therein.  If, in any judicial proceeding, a court shall 
refuse to enforce any of such separate covenants, then such unenforceable 
covenants shall be deemed eliminated from the provisions hereof for the 
purpose of such proceedings to the extent necessary to permit the remaining 
separate covenants to be enforced in such proceedings.  If, in any judicial 
proceeding, a court shall refuse to enforce any one or more of such separate 
covenants because the total time thereof or the geographic area covered 
thereby is deemed to be excessive or unreasonable, then it is the intent of 
the parties hereto that such covenants, which would otherwise be 
unenforceable due to such excessive or unreasonable period of time or 
geographic area, be enforced for such lesser period of time as shall be 
deemed reasonable and not excessive by such court.

13.  ENTIRE AGREEMENT; AMENDMENT.

     This Agreement contains the entire agreement between the Company and the 
Employee with respect to the subject matter hereof and thereof.  This 
Agreement may not be amended, waived, changed, modified or discharged except 
by an instrument in writing executed by or on behalf of the party against 
whom enforcement of any amendment, waiver, change, modification or discharge 
is sought.  No course of conduct or dealing shall be construed to modify, 
amend or otherwise affect any of the provisions hereof.

            NON-QUALIFIED STOCK OPTION CERTIFICATE AND AGREEMENT

                              Pursuant to the
                             Telereunion, Inc.
               1995 Stock Option and Appreciation Rights Plan

     THIS AGREEMENT is effective as of September 30, 1995, by and between 
Telereunion, Inc., a Delaware corporation (the "Company") and 
__________________ (the "Optionee").

     WHEREAS, the Optionee is a valued and trusted officer, director, 
employee or consultant of the Company and the Company considers it desirable 
and in its best interests that the Optionee be given an inducement to acquire 
a proprietary interest in the Company and an added incentive to advance the 
interest of the Company by possessing an option to purchase the Common Stock, 
$.001 par value, of the Company, in accordance with the Telereunion, Inc. 
1995 Stock Option and Appreciation Rights Plan as amended (the "1995 Plan") 
adopted by the Board of Directors of the Company in July 28, 1995 and 
approved by the shareholders of the Company in April 1995 and as thereafter 
amended.  

     Now, therefore, in consideration of the premises, it is agreed by and 
between the parties as follows:

     1.   The Company hereby grants to the Optionee the right, privilege and 
option to purchase 51,636 shares of the Common Stock, $.001 par value, of the 
Company subject in all respects to the terms and provisions of the 1995 Plan, 
as it may be amended from time to time, which 1995 Plan and amendments, if 
any, are incorporated by reference herein (the "Options").

     2.   The Options represent options which do not qualify as "incentive stock
options" under Section 422A of the Internal Revenue Code of 1986, as amended.

     3.   The option price as determined by the Board of Directors of the 
Company is Sixty-Five ($.65) per share.

     4.   The Options shall vest and become immediately exercisable.

     5.   Options that are the subject of this Agreement, to the extent not 
theretofore exercised, shall expire on September 30, 2005 (being the 
expiration of ten (10) years from the effective date of grant of this Option) 
and shall terminate in accordance with Section 6 of the 1995 Plan.

     6.   The Options may not be exercised if the issuance of shares upon 
such exercise would constitute a violation of any applicable federal or state 
securities or other law or valid regulation. Optionee, as a condition to his 
exercise of any Options, shall represent to the Company that the shares of 
Common Stock which he acquires upon exercise of any Options are being 
acquired by him for investment and not with a present view to distribution or 
resale, unless counsel for the Company is then of the opinion that such a 
representation is not required under 


<PAGE>

the Securities Act of 1933, as amended, or any other applicable law, 
regulation or rule of any governmental agency.  Optionee agrees as a 
condition precedent to exercise of any portion of the Options that he shall 
furnish whatever documentation may be reasonably requested by the Company to 
ensure compliance with the applicable law and the terms and conditions of 
this Certificate and the 1995 Plan.

     7.   The Options granted hereby may not be transferred in any manner 
otherwise than by will or the laws of descent or distribution and may be 
exercised during the lifetime of the Optionee only by the Optionee.  The 
terms of this Certificate shall be binding upon the executors, 
administrators, heirs, successors and assigns of the Optionee.

     8.   Subject to any provision herein that may provide for the earlier 
termination of the Options, no Option may be exercised more than ten (10) 
years from the date of grant of the Options. During such period, the Options 
may be exercised only in accordance with the terms hereof and the provisions 
of the 1995 Plan.

     9.   Capitalized terms used herein and not defined herein shall have the 
meaning set forth in the 1995 Plan.

Directors upon any questions arising under the 1995 Plan.  Optionee

compensation payable to him and any taxes required to be withheld by federal, 
state or local law as a result of the exercise of the Options.

                             FIRST AMENDMENT TO

                           STOCK OPTION AGREEMENT

     Reference is made to the Non-Qualified Stock Option Certificate and 
Agreement, dated effective as of September 30, 1995 (the "Original 
Agreement"), between Telereunion, Inc., a Delaware corporation 
("Telereunion"), and the undersigned optionee (the "Optionee").  Unless 
otherwise indicated, capitalized terms used in this Amendment have the 
meanings assigned to such terms in the Original Agreement.

     Pursuant to the Original Agreement, the Optionee was granted the option 
(the "Option") to purchase _________ shares of common stock, $.001 par value 
per share, of Telereunion at an exercise price of $.65 per share, on the 
terms and subject to the conditions set forth in the Original Agreement. 
Pursuant to that certain Agreement and Plan of Merger (the "Agreement") dated 
April 29, 1996 between Polish Telephones and Microwave Corporation, a Texas 
corporation (the "Company"), PTMC Acquisition Sub, Inc., a Delaware 
corporation, Telereunion, and the stockholders of Telereunion referenced 
therein, the Company acquired all of the issued and outstanding common stock 
of Telereunion.  Under the terms of the Agreement, certain options 
outstanding under Telereunion's 1995 Stock Option and Appreciation Rights 
Plan, as amended (the "Plan"), including the Option, are to be converted and 
amended to provide for the right to acquire shares of common stock, $.001 par 
value per share, of the Company ("Common Stock") at an exercise price of 
$1.35 per share.  The Company and the Optionee desire to convert and amend 
the Original Agreement to provide for the right to purchase shares of Common 
Stock, to reduce the number of shares of Common Stock subject to the Option 
and to increase the exercise price of the Option, as set forth in this 
Amendment.  Therefore, the Company and the Optionee hereby agree as follows:

     1.  The name of the corporation that issued the Option, and whose common 
stock may be acquired upon exercise of the Option, is hereby changed to 
Polish Telephones and Microwave Corporation, a Texas corporation.

     2.  The total number of shares of Common Stock that may be acquired upon 
exercise in full of the Option is hereby decreased to 25,000 shares.

     3.  The exercise price per share applicable to the Option is hereby 
increased to $1.35 per share.

     4.  Except as expressly set forth in the three preceding paragraphs, all 
of the terms and conditions of the Original Agreement will remain in effect 
following the date hereof.

          THESE SECURITIES (A) HAVE NOT BEEN REGISTERED UNDER THE SECURITIES 
     ACT OF 1933.  THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, OR 
     HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT 
     RELATED THERETO OR AN OPINION OF COUNSEL, REASONABLY SATISFACTORY TO THE 
     COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT 
     OF 1933.

         WARRANT TO PURCHASE SHARES OF COMMON STOCK, $0.001 PAR VALUE
          PER SHARE, OF POLISH TELEPHONES AND MICROWAVE CORPORATION

       THIS CERTIFIES that, for value received, Robert Chamberlain (the  
"Warrantholder"), is entitled, upon the terms and subject to the 
conditions hereinafter set forth, to purchase from Polish Telephones and 
Microwave Corporation, a Texas corporation (the "Company"), that number 
of fully paid and nonassessable shares of the Company's common stock, 
$0.001 par value per share (the "Common Stock"), at the purchase price 
per share (the "Exercise Price") as set forth in Section 1 below.  The 
number of shares and Exercise Price are subject to adjustment as 
provided in Section 10 below.

     1.  NUMBER OF SHARES; EXERCISE PRICE; TERM.

        (a)  This Warrant is exercisable for 79,191 shares (the "Shares") 
of Common Stock at a purchase price of $2.19 per share (the "EXERCISE 
PRICE").



         (b) Subject to the terms and conditions set forth in this 
Warrant, this Warrant will be exercisable during the term commencing on 
the date of this Warrant and ending on, May  , 2001.

     2.  TRANSFER AND EXCHANGE.  This Warrant and all options and 
rights under this Warrant are transferable, as to all or any part of the 
number of Shares issuable under the terms of this Warrant, by the holder 
of this Warrant, in person or by duly authorized attorney, on the books 
of the Company upon surrender of the Warrant at the principal offices of 
the Company, together with the attached, properly endorsed, Assignment 
Form.  Absent any such transfer, the Company may deem and treat the 
registered holder of this Warrant at any time as the absolute owner of 
the Warrant for all purposes and will not be affected by any notice to 
the contrary.  If this Warrant is transferred in part, the Company will, 
at the time of surrender, issue to the transferee a Warrant covering the 
number of issuable Shares transferred and to the transferor a Warrant 
covering the number of issuable Shares not transferred.

     3. EXERCISE.

          (a)  This Warrant may be exercised as to all or any of the from 
     time to time on any Business Day (as defined in Section 9 below).  In 
     order to exercise this Warrant, in whole or in part, the holder will 
     deliver to the Company at its principal offices (i) a written notice of 
     such holder's election to exercise its Warrant, substantially in the 
     form of the Warrant Exercise Notice attached to this Warrant, (ii) 
     payment of the Exercise Price, in an amount equal to the aggregate 
     purchase price for all Shares to be purchased pursuant to such exercise, 
     and (iii) the Warrant.  Upon receipt of such notice, the Company will, 
     as promptly as practicable, and in any event within ten (10) Business 
     Days, execute, or cause to be executed, and deliver to such holder a 
     certificate or certificates representing the aggregate number of full 
     shares of Common Stock issuable upon such exercise.  The stock 
     certificate or certificates so delivered will be in such denominations 
     as may be specified in such notice and will be registered in the name of 
     such holder, or such other name as designated in such notice.  A Warrant 
     will be deemed to have been exercised, such certificate or certificates 
     will be deemed to have been issued, and such holder or any other person 
     or entity so designated or named in such notice will be deemed to have 
     become a holder of record of such shares for all purposes, as of the 
     date that such notice (together with payment of the Exercise Price and 
     the Warrant) is received by the Company.  If the Warrant has been 
     exercised in part, the Company will, at the time of delivery of such 
     certificate or certificates, either deliver to such holder a new Warrant 
     evidencing the rights of such holder to purchase a number of Shares with 
     respect to which the Warrant has not been exercised, which new Warrant 
     will, in all other respects, be identical to this Warrant, or, at the 
     request of such holder, appropriate notation may be made on the Warrant 
     and the Warrant returned to such holder.

          (b)  Payment of the Exercise Price will be made, at the option of 
     the holder, by (i) company or individual check (subject to collection), 
     certified or official bank check or (ii) cancellation of any debt owed 
     by the Company to the holder.  If the holder surrenders a combination of 
     cash or cancellation of any debt owed by the Company to the holder, the 
     holder will specify the respective number of shares of Common Stock to 
     be purchased with each form of consideration, and the foregoing 
     provisions will be applied to each form of consideration with the same 
     effect as if the Warrant were being separately exercised with respect to 
     each form of consideration; PROVIDED, HOWEVER, that a holder may 
     designate that any cash to be remitted to a holder in payment of debt be 
     applied, together with other monies, to the exercise of the portion of 
     the Warrant being exercised for cash.

     4.  NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip 
representing fractional shares will be issued upon the exercise of this 
Warrant.  In lieu of any fractional share to which a holder would otherwise 
be entitled, such holder will be entitled to receive, at its option, either 
(i) a cash payment equal to the excess of fair market value for such 
fractional share above the Exercise Price for such fractional share (as 
mutually determined by the Company and the holder) or (ii) a whole share if 
the holder tenders the Exercise Price for one whole share.

     5.  CHARGES, TAXES AND EXPENSES.  Issuance of certificates for shares 
upon the exercise of this Warrant will be made without charge to the holder 
for any issue or transfer tax or other incidental expense in respect of the 
issuance of such certificates, all of which taxes and expenses will be paid 
by the Company.

     6.  NO RIGHTS AS SHAREHOLDERS.  This Warrant does not entitle the holder 
to any voting rights, dividend rights or other rights as a shareholder of the 
Company prior to exercise.

     7.  WARRANT REGISTER.  The Company will, at all times while this Warrant 
remains outstanding and exercisable, keep and maintain at its principal 
office a register in which the registration, transfer, and exchange of the 
Warrant will be provided for.  The Company will not at any time, except upon 
the dissolution, liquidation, or winding up of the Company, close such 
register so as to result in preventing or delaying the exercise or transfer 
of any Warrant.

     8.  LOST, STOLEN, MUTILATED, OR DESTROYED WARRANT.  If this Warrant is 
lost, stolen, mutilated, or destroyed, the Company will issue a new Warrant 
of like denomination, tenor, and date upon receipt of and appropriate 
affidavit and indemnity executed by the Holder.  Any such new Warrant will 
constitute an original contractual obligation of the Company, whether or not 
the allegedly lost, stolen, mutilated, or destroyed Warrant is at any time 
enforceable by any person or entity.

     9.  BUSINESS DAYS.  A "Business Day" is any day other than Saturday, 
Sunday, or legal holiday.  If the last or appointed day for the taking of any 
action or the expiration of any right required or granted in this Warrant is 
not a Business Day, then such action may be taken or such right may be 
exercised on the following Business Day.

     10.  ADJUSTMENTS.

     (a)  ADJUSTMENT EVENTS.   The Warrant will be exercisable for the number 
of shares of Common Stock in such manner that, following the complete and 
full exercise of this Warrant, the amount of Common Stock and other property 
issued to the holder of this Warrant will equal the aggregate number of 
shares of Common Stock set forth in Section 1(a), as adjusted, to the extent 
necessary, to give effect to the following events:

               (i) (A)  The holder of this Warrant will be entitled to an 
          adjustment as set forth in Section 10(a)(i)(B), if at any time or 
          from time to time, the holders of any class of Common Stock or any 
          option, warrant, right, or similar security exercisable into or 
          exchangeable for Common Stock ("Common Stock Equivalent") have 
          received, or (on or after the record date fixed for the 
          determination of shareholders eligible to receive) have become 
          entitled to receive, without payment therefor, (I) property (other 
          than cash) by way of dividend or distribution; or (II) property 
          (including cash) by way of spin-off, split-up, reclassification 
          (including any reclassification in connection with a consolidation 
          or merger in which the Company is the surviving corporation), 
          recapitalization, 


                                      3

<PAGE>

          combination of shares into a smaller number of shares, or similar 
          corporate restructuring.

                        (B)  In each such case, the holder of this Warrant 
          will be entitled to receive for each share of Common Stock issuable 
          under this Warrant as of the record date fixed for such 
          distribution, the greatest per share amount of property received or 
          receivable by any holder of any class of Common Stock or Common 
          Stock Equivalent.  With respect to any subsequent distribution, all 
          such consideration receivable pursuant to this Section 10(a)(i) 
          will be deemed outstanding and owned by the holder when determining 
          the amount of consideration due to the holder upon exercise of the 
          Warrant.

                        (C)  This Section 10(a)(i) does not apply to 
          additional shares of Common Stock issued as a stock dividend or in 
          a stocksplit.

                   (ii)  If at any time there occurs any stock split, stock 
          dividend, reverse stock split, or other subdivision of the Common 
          Stock, then the number of shares of Common Stock to be received and 
          the Exercise Price to be paid will be proportionately adjusted.

                   (iii) (A)  The following events will constitute   
          "Reorganization Events": (I) any reclassification or change of 
          outstanding shares of any class of Common Stock or Common Stock 
          Equivalent (other than a change in par value, or from par value to 
          no par value, or from no par value to par value), or (II) any 
          consolidation of the Company with, or merger or share exchange of 
          the Company with or into, another entity, or (III) any sale of all 
          or substantially all of the property, assets, business, income or 
          revenue generating capacity, or goodwill of the Company.


                   (B)  Upon the occurrence of a Reorganization Event, 
          the Company, or the successor or other entity, as the case may be, 
          will provide that the holder of this Warrant will receive the 
          highest per share kind and amount of consideration (including cash) 
          received or receivable upon such Reorganization Event by any holder 
          of any class of Common Stock or Common Stock Equivalent for each 
          Share issuable under this Warrant immediately prior to such 
          Reorganization Event (as adjusted pursuant to Section 10(a)(i)).  
          Any such successor entity, which thereafter will be deemed to be 
          the Company for purposes of this Warrant, will provide for 
          adjustments that are as nearly equivalent as may be possible to the 
          adjustments provided for by this Section 10.

                   (v)  In case any event occurs as to which the preceding 
          Sections 10(a)(i) through (iii) are not strictly applicable, but as 
          to which the failure to make any adjustment would not fairly 
          protect the purchase rights represented by the Warrants in 
          accordance with the essential intent and principles of this Section 
          10, then, in each such case, the holder and the Company will 
          negotiate for 30 days in 


                                      4

<PAGE>

          good faith in an attempt to reach a mutually agreeable solution.  
          If, at the end of such 30-day period the Company and the holder have 
          not reached such an agreement, the holder may appoint an 
          independent investment bank or firm of independent public 
          accountants reasonably acceptable to the Company, which will give 
          its opinion as to the adjustment, if any, on a basis consistent 
          with the essential intent and principles established in this 
          Section 10, necessary to preserve the purchase rights represented 
          by this Warrant.  Upon receipt of such opinion, the Company will 
          promptly deliver a copy of such opinion to the holder and will make 
          the adjustments described in such opinion.  The fees and expenses 
          of such investment bank or independent public accountants will be 
          borne equally by the Company and the holder.

          (b)  ROUNDING.  Any calculation under this Section 10 will be 
     made to the nearest one ten-thousandth of a share and the number of 
     issuable Shares resulting from such calculation will be rounded up to 
     the next whole share of Common Stock comprising issuable Shares.

          (c)  NOTICE OF EVENTS.

               (i)  In the event of (A) any setting by the Company of a 
          record date with respect to the holders of any class of the capital 
          stock of the Company for the purpose of determining which of such 
          holders are entitled to dividends, repurchases of securities or 
          other distributions, or any right to subscribe for, purchase or 
          otherwise acquire any shares of such capital stock or other property
          or to receive any other right; or (B) any capital reorganization of 
          the Company, or reclassification or recapitalization of the capital 
          stock of the Company or any transfer of all or a majority of the 
          assets, business, or revenue or income generating capacity of the 
          Company, or consolidation, merger, share exchange, reorganization, 
          or similar transaction involving the Company; or (C) any voluntary 
          or involuntary dissolution, liquidation, or winding up of the 
          Company; or (D) any proposed issue or grant by the Company of any 
          capital stock of the Company, or any right or option to subscribe 
          for, purchase, or otherwise acquire any captial stock of the 
          Company (other than the issue of Issuable Warrant Shares upon 
          exercise of this Warrant), then, in each such event, the Company 
          will deliver or cause to be delivered to the holders a notice 
          specifying, as the case may be, (I) the date on which any such 
          record is to be set for the purpose of such dividend, distribution, 
          or right, and stating the amount and character of such dividend, 
          distribution, or right; (II) the date as of which the holders of 
          record will be entitled to vote on any reorganization, 
          reclassification, recapitalization, transfer, consolidation, 
          merger, share exchange, conveyance, dissolution, liquidation, or 
          wihding-up; (III) the date on which any such reorganization, 
          reclassification, recapitalization, transfer, consolidation, 
          merger, share exchange, conveyance, dissolution, liquidation, or 
          winding-up is to take place and the time, if any is to be fixed, as 
          of which the holders of record of any class of capital stock of the 
          Company will be entitled to exchange their shares of capital stock 
          for securities or other property deliverable upon such event; (IV) 
          the


                                      5

<PAGE>

          amount and character of any capital stock, property, or rights 
          proposed to be issued or granted, the consideration to be received 
          therefor, and, in the case of rights or options, the exercise price 
          thereof, and the date of such proposed issue or grant and the 
          persons or class of persons to whom such proposed issue or grant 
          will be offered or made; and (V) such other information as the 
          holders may reasonably request.  Any such notice will be deposited 
          in the United States mail, postage prepaid, at least thirty (30) 
          days prior to the date therein specified, and notwithstanding 
          anything in this Agreement or this Warrant to the contrary the 
          holders may exercise this Warrant within thirty (30) days from the 
          receipt of such notice.


               (ii)  If there is any adjustment as provided above in 
          Section 10(a), the Company will immediately cause written notice 
          thereof to be sent to the holder, which notice will be accompanied 
          by a certificate of the independent public accountants of the 
          Company setting forth in reasonable detail the facts requiring any 
          such adjustment in the number of shares receivable after such 
          adjustment.  At the request of the holder and upon surrender of 
          this Warrant of such holder, the Company will reissue this Warrant 
          of such holder in a form conforming to such adjustments.

     11.  ASSURANCES.  The Company will not by any action including, without 
limitation, amending, or permitting the amendment of, the charter documents, 
bylaws, or similar instruments of the Company or through any reorganization, 
reclassification, transfer of assets, consolidation, merger, share exchange, 
dissolution, issue or sale of securities, or any other similar voluntary 
action, avoid or seek to avoid the observance or performance of any of the 
terms of this Warrant, but will at all times in good faith assist in the 
carrying out of all such terms and in the taking of all such actions as may 
be necessary or appropriate to protect the rights of the holder against 
impairment or dilution.  Without limiting the generality of the foregoing, 
the Company will, with respect to this Warrant, (i) take all such action as 
may be necessary or appropriate in order that the Company may validly and 
legally issue fully paid and nonassessable shares of Common Stock, free and 
clear of all liens, encumbrances, equities, and claims and (ii) use its best 
efforts to obtain all such authorizations, exemptions, or consents from any 
public regulatory body having jurisdiction as may be necessary to enable the 
Company to perform its obligations under this Warrant.

     12.  MISCELLANEOUS.

          (a)  SUCCESSORS.  This Warrant will be binding upon any successors 
or assigns of the Company.

          (b)  GOVERNING LAW.  THIS WARRANT WILL CONSTITUTE A CONTRACT UNDER 
THE LAWS OF TEXAS AND FOR ALL PURPOSES WILL BE CONSTRUED IN ACCORDANCE WITH 
AND GOVERNED BY THE LAWS OF SAID STATE, WITHOUT GIVING EFFECT TO THE CONFLICT 
OF LAWS PRINCIPLES OR ANY OTHER PRINCIPLE THAT COULD REQUIRE THE APPLICATION 
OF THE LAWS OF ANY OTHER JURISDICTION.
