ITEM 5.  OTHER EVENTS

View Tech, Inc. and its wholly-owned subsidiary, USTeleCenters, Inc.
(collectively "the Company") entered into a $15 million credit agreement (the
"Agreement"), with Imperial Bank (the "Bank"), effective November 21, 1997.  The
Agreement provides for a maximum credit line of up to $15 million for a term of
five (5) years.  Amounts outstanding under the Agreement are collateralized by
the assets of the Company.  Funds available under the Agreement will vary from
time to time depending on many variables including, without limitation, the
amount of Eligible Trade Accounts Receivable and Eligible Inventory of the
Company, as such terms are defined in the Agreement. The interest rates charged
on outstanding principal amounts vary between the Prime Rate, plus the Prime
Rate Margin, or between the Eurodollar Rate, plus the Eurodollar Rate Margin,
depending upon the Company's Leverage Ratio, as such terms are defined in the
Agreement. The Agreement requires the Company to comply with various financial
and operating loan covenants. Under certain conditions, the Agreement allows the
Company to prepay principal amounts outstanding without penalty. The Agreement
replaced the Company's previous credit agreements with BankBoston and City
National Bank.

The Agreement provides for three separate loan commitments consisting of (i) a
Facility A Commitment up to $7 million; (ii) a Facility B Commitment up to $5
million and (iii) a Facility C Commitment up to $3 million.  Amounts drawn under
the Facility A Commitment are due and payable no later than November 21, 2002.
Amounts drawn under the Facility B Commitment are subject to mandatory
repayments in sixteen (16) equal quarterly installments commencing on March 31,
1999.  Amounts outstanding under the Facility C Commitment are subject to
mandatory repayments in twelve (12) equal quarterly installments commencing on
March 31, 2000.  All amounts outstanding under each such Facility are due and
payable no later than November 21, 2002.  The Agreement prohibits the payment of
dividends to shareholders of View Tech, Inc.

In connection with the Agreement, the Company issued a Common Stock Purchase
Warrant for the purchase of 60,000 shares of the Company'' Common Stock by the
Bank and a Common Stock Purchase Warrant for the purchase of 20,000 shares of
the Company's Common Stock by BankBoston, N.A., a national banking association
(collectively, the "Warrants"), a participating lender.  The Warrants are
exercisable until November 21, 2004 at a purchase price of $7.08 per share.

Obligations of the Borrower hereunder or under such Notes to make payments of
principal of or interest on the Loans when due.

                                                              ------------------

   SECTION 3.7.2.  SETOFF.  Each Principal Company agrees that, regardless of

the adequacy of any Collateral, the Agent and each Bank shall continue to have
all rights of set-off and bankers' liens provided by Applicable Law, and, in
addition thereto, each Principal Company further agrees that, if at any time any
amount owing by such Principal Company under this Agreement or the Notes is then
due to the Agent or any Bank, the Agent or such Bank may, regardless of the
adequacy of any Collateral, apply to the payment of such amount any and all
balances, credits, deposits, accounts or moneys of such Principal Company then
or thereafter deposited with or held by such Bank and will promptly notify such
Principal Company (it being understood that the failure to give any such notice
shall not affect the rights of the Agent or the Banks hereunder).

   SECTION 3.7.3.  DUE DATE EXTENSION.  If any payment of principal of or
                   ------------------

then such due date shall be extended to the next following Business Day (unless,
in the case of interest due on the principal amount of any Eurodollar Loan, such
next following Business Day is the first day of a calendar month, in which case
such due date shall be the immediately preceding Business Day), and additional

     SECTION 3.7.4.  NOTICES OF CHANGES IN PRIME RATE; NOTICE OF EURODOLLAR 
                   ------------------------------------------------------ 
RATES.  Changes in the rate of interest on any Prime Rate Loans shall take 
- -----
effect simultaneously with each change in the Prime Rate. The Agent shall give
notice promptly to the Borrower and the Banks of changes in the Prime Rate. The
applicable Eurodollar Rate for each Interest Period shall be determined by the
Agent, and notice thereof shall be given by the Agent promptly to the Borrower
and each Bank. Each determination of the Prime Rate and the applicable
Eurodollar Rate by the Agent shall be conclusive and binding upon the parties
hereto, in the absence of manifest error. The Agent shall, upon written request
of the Borrower or any Bank, deliver to the Borrower or such Bank a statement
showing in reasonable detail the computations used by the Agent in determining
any applicable Eurodollar Rate hereunder.

     SECTION 3.7.5.  COMPUTATIONS.  Interest and Commitment Fees shall be 
                     ------------

     SECTION 3.7.6.  RECORDKEEPING.  Each Bank shall record in its records, or
                     -------------                                            
at its option on the grid attached to each of its Notes, the date and amount of
each of the Loans and other Credit Extensions made by such Bank, each repayment
and prepayment thereof and, in the case of each Eurodollar Loan, the principal
amount thereof and the dates on which each Interest Period for such Loan shall
begin and end.  The aggregate unpaid principal amount so recorded shall be
rebuttable presumptive evidence of the principal amount owing and unpaid on such
Note.  The failure to so record any such amount or any error in so recording any
such amount shall not, however, limit or otherwise affect the obligations of any
Principal Company hereunder or under any Note to repay the principal amount of
the Loans or other Credit Extensions evidenced by such Note together with all
interest accruing thereon.

   SECTION 3.8.  TAXES.  All payments of principal of and interest on the Notes
                 -----                                                         
and of all Fees and other sums payable hereunder or under any of the other Loan
Documents shall be made free and clear of and without deduction for any present
or future income, excise, stamp or franchise taxes or other taxes, fees, duties,
withholdings or charges of any nature whatsoever imposed by any Governmental
Authority, but excluding franchise taxes imposed on the Agent or any Bank and
taxes imposed on the Agent or any Bank measured by such Person's net income or
receipts imposed by the jurisdiction where such Person's principal lending
office is located (all non-excluded items being called "Taxes"). If any
                                                        -----
withholding or deduction from any such payment to be made hereunder or under any
of the other Loan Documents is required in respect of any Taxes pursuant to any
Applicable Law, then the Borrower or other Principal Company obligated to make
such payment will:
<PAGE>
 
                                     -55-

          (a)  pay directly to the relevant Governmental Authority the full
     amount required to be so withheld or deducted;

          (b)  promptly forward to the Agent and each affected Bank an official
     receipt or other documentation satisfactory to the Agent evidencing that
     the Borrower or other Principal Company obligated to make such payment has
     made such payment to such Governmental Authority; and

          (c)  pay to the Agent such additional amounts as are necessary to
     ensure that the net amount actually received by each affected Bank will
     equal the full amount such Bank would have received had no such withholding
     or deduction been required.

     Moreover, if any Taxes are directly asserted against the Agent or any Bank
with respect to any payment received by the Agent or such Bank hereunder or
under any of the other Loan Documents, the Agent or such Bank may pay such Taxes
and the Borrower or other Principal Company obligated to make such payment will
promptly pay such additional amounts (including any penalty, interest or
expense) as are necessary in order that the net amount received by the Agent or
such Bank after the payment of such Taxes (including any Taxes on such
additional amount) shall equal the amount the Agent or such Bank would have
received had such Taxes not been asserted.

     If any Principal Company fails to pay any Taxes when due to the appropriate
Governmental Authority or fails to remit to the Agent when due any payments
required by this Section 3.8 or any required receipts or other required
                 -----------                                           
documentary evidence, the Borrower or other Principal Company shall indemnify
the Agent and each of the Banks for any incremental Taxes, interest or penalties
that may become payable by the Agent or any of the Banks as a result of any such
failure and shall promptly pay to the Agent any amounts not paid when due to the
Agent as required by this Section 3.8.
                          ----------- 

     SECTION 3.9.  USE OF PROCEEDS.  The Borrower covenants and agrees that the
                   ---------------                                             
entire proceeds of all Loans and other Credit Extensions made pursuant hereto
will be used and applied by the Borrower as follows: (a) with respect to the
Facility A Loans (including Letters of Credit) and Facility B Loans, for working
capital and other general corporate purposes not prohibited by this Agreement
(including, without limitation, the financing of Permitted Acquisitions and the
repayment on the Closing Date of the entire amount of outstanding obligations of
the Principal Companies under the credit facilities described on Schedule 3.9)
                                                                 ------------
and (b) with respect to the Facility C Loans, to finance Permitted Acquisitions
by the Principal Companies.

     end on a day which is not a Business Day shall end on the immediately
     succeeding Business Day (unless such immediately succeeding Business Day is
     the first Business Day of a calendar month, in which case such Interest
     Period shall end on the immediately preceding Business Day);

          (b) the Borrower may not select any Interest Period for any principal
     of any Loan which would end after the Maturity of such principal; and

          (c) absent the timely selection of a new Interest Period for a then
     outstanding Eurodollar Loan, or any part thereof, such Eurodollar Loan or
     such part, as the case may be, shall, immediately upon the expiration of
     such Interest Period, automatically and without further action, be
     converted into a Prime Rate Loan.

     SECTION 4.4.2.  CONDITIONS PRECEDENT.  No portion of the outstanding 
                     -------------------- 
principal amount of any Loan may be continued as, or converted into, one or more
Eurodollar Loans unless, on and as of the requested date of continuation or
conversion, as the case may be, all of the conditions precedent set forth in
Section 7.2 have been satisfied.

     SECTION 4.4.3.  OTHER LIMITATIONS.  At all times:
                     ----------------- 

          (a) the aggregate principal amount of each Group of Eurodollar Loans

                                     -58-

          (b) the total number of Eurodollar Loans in effect at any time shall
     not exceed six (6).

     SECTION 4.5.  INCREASED COSTS.
                   --------------- 

          (a) If (i) Regulation D of the F.R.S. Board, or (ii) after the date
     hereof, the adoption of any Applicable Law, or any change therein or in any
     existing Applicable Law, or any change in the interpretation or
     administration thereof by any Governmental Authority charged with the
     interpretation or administration thereof, or compliance by any Bank (or any
     Eurodollar Office of such Bank) with any request or directive (whether or
     not having the force of law) of any such Governmental Authority:

               (A) shall subject any Bank (or any Eurodollar Office of such
          Bank) to any tax, duty or other charge with respect to the Eurodollar
          Loans, its Notes or its obligation to make Eurodollar Loans available,
          or shall change the basis of taxation of payments to any Bank of the
          principal of or interest on its Eurodollar Loans or any other amounts
          due under this Agreement in respect of its Eurodollar Loans or its
          obligation to make Eurodollar Loans available (except for changes in
          the rate of tax on the overall net income of such Bank or its
          Eurodollar Office imposed by the jurisdiction in which such Bank's
          principal executive office or Eurodollar Office is located); or

               (B) shall impose, modify or deem applicable any reserve
          (including, without limitation, any reserve imposed by the F.R.S.
          Board), special deposit or similar requirement against assets of,
          deposits with or for the account of, or credit extended by, any Bank
          (or any Eurodollar Office of such Bank); or

               (C) shall impose on any Bank (or its Eurodollar Office) any other
          condition affecting its Eurodollar Loans, its Notes or such Bank's
          obligation to make Eurodollar Loans available;

     and the result of any of the foregoing is to increase the cost to (or in
     the case of Regulation D referred to above, to impose a cost on) such Bank
     (or any Eurodollar Office of such Bank) of making or maintaining any
     Eurodollar Loan, or to reduce the amount of any sum received or receivable
     by such Bank (or its Eurodollar Office) under this Agreement or under its
     Notes with respect thereto, then upon demand by such Bank, the Borrower
     shall pay directly to such 
<PAGE>
 
                                     -59-

     Bank such additional amount as will compensate such Bank for such increased
     cost or such reduction.

          (b) If any Bank shall reasonably determine that the adoption or phase-
     in of any Applicable Law regarding capital adequacy, or any change therein
     or in any existing Applicable Law, or any change in the interpretation or
     administration thereof by any Governmental Authority charged with the
     interpretation or administration thereof, or compliance by any Bank (or its
     Eurodollar Office) or any Person controlling such Bank with any request or
     directive regarding capital adequacy (whether or not having the force of
     law) of any such Governmental Authority, has or would have the effect of
     reducing the rate of return on such Bank's or such controlling Person's
     capital as a consequence of such Bank's obligations hereunder (including,
     without limitation, the Commitments) to a level below that which such Bank
     or such controlling Person could have achieved but for such adoption,
     phase-in, change or compliance (taking into consideration such Bank's or
     such controlling Person's policies with respect to capital adequacy) by an
     amount deemed by such Bank or such controlling Person to be material, then
     such Bank shall promptly after its determination of such occurrence give
     notice thereof to the Borrower.  The Borrower and such Bank shall
     thereafter attempt to negotiate in good faith an adjustment to the
     compensation payable hereunder which will adequately compensate such Bank
     for such reduction.  If the Borrower and the Bank are unable to agree to
     such adjustment within thirty (30) days of the day on which the Borrower
     receives such notice (but not earlier than the effective date of any such
     applicability, change, interpretation, administration or compliance), the
     Borrower shall pay such additional amounts which will, in such Bank's
     reasonable determination, evidenced by calculations in reasonable detail
     furnished to the Borrower, compensate such Bank or such controlling Person
     for such reduction.  In determining such amount, a Bank may use any
     reasonable methods of averaging, allocating or attributing such reductions
     among its customers.

     SECTION 4.6.  INTEREST RATE INADEQUATE OR UNFAIR.  If with respect to any 
                   ---------------------------------- 
Interest Period:

          (a) deposits in Dollars (in the applicable amounts) are not being
     offered to one or more Banks in the relevant market for such Interest
     Period, or the Agent otherwise determines (which determination shall be
     binding and conclusive on the Borrower) that by reason of circumstances
     affecting the interbank eurodollar 
<PAGE>
 
                                     -60-

     market, adequate and reasonable means do not exist for ascertaining the
     applicable Eurodollar Rate; or

          (b) the Required Banks determine that the Eurodollar Rate (Reserve
     Adjusted) as determined by the Agent will not adequately and fairly reflect
     the cost to such Banks of maintaining or funding Eurodollar Loans for such
     Interest Period, or that the maintaining or funding of Eurodollar Loans has
     become impracticable as a result of an event occurring after the date of
     this Agreement which in the opinion of such Banks materially affects
     Eurodollar Loans;

     then the Agent shall promptly notify the Borrower and the Banks, so long as
     ----                                                                       
     such circumstances shall continue, (i) no Bank shall thereafter have any
     obligation to fund or make available Eurodollar Loans and (ii) on the last
     day of the current Interest Period for any Eurodollar Loan, such Eurodollar
     Loan shall, unless then repaid in full, automatically convert to a Prime
     Rate Loan.

     SECTION 4.7.  CHANGES IN LAW RENDERING EURODOLLAR LOANS UNLAWFUL.  In the 
                   -------------------------------------------------- 
event that the adoption or phase-in of any Applicable Law, or any change therein
or in any existing Applicable Law or any change in the interpretation thereof by
any Governmental Authority charged with the interpretation or administration
thereof, shall make it (or in the good faith judgment of any Bank cause a
substantial question as to whether it is) unlawful for any Bank to maintain or
fund Eurodollar Loans, then such Bank shall promptly notify the Borrower, the
other Banks and the Agent and, so long as such circumstances shall continue, (a)
such Bank shall thereafter have no obligation to fund or make available
Eurodollar Loans and (b) on the last day of the current Interest Period for any
Eurodollar Loan (or, in any event, on such earlier date as may be required by
the relevant Applicable Law), such Eurodollar Loan shall, unless then repaid in
full, automatically convert to a Prime Rate Loan.

     SECTION 4.8.  FUNDING LOSSES.  The Borrower hereby agrees that, upon demand
                   -------------- 
by any Bank, the Borrower will indemnify such Bank against any net loss or
expense which such Bank may sustain or incur (including, without limitation, any
net loss or expense reasonably incurred by reason of the liquidation or
employment of deposits or other funds acquired by such Bank to maintain or fund
any Eurodollar Loan), as reasonably determined by such Bank, as a result of (a)
any payment, repayment, prepayment or conversion of any Eurodollar Loan of such
Bank on a date other than the last day of an Interest Period for such Eurodollar
Loan (including any conversion pursuant to Section 4.7) or (b) any failure of
                                           -----------

date specified therefor in a notice of borrowing pursuant to Section 3.1 or in

                                               -----------    --- 

     SECTION 4.9.  DISCRETION OF BANK AS TO MANNER OF FUNDING.  Notwithstanding 
                   ------------------------------------------ 
any provision of this Agreement to the contrary, each Bank shall be entitled to
maintain and fund all or any part of any of the Loans in any manner it sees fit,
it being understood, however, that for purposes of this Agreement all
determinations hereunder (including determinations of any net loss or expense
under Section 4.8) shall be made as if such Bank had actually funded and 
      -----------                                                   
maintained each Eurodollar Loan during each Interest Period for such Eurodollar
Loan through the purchase of a deposit on the first day of such Interest Period
having a principal amount equal to the principal amount of such Eurodollar Loan,
having a maturity corresponding to such Interest Period and bearing an interest
rate equal to the Eurodollar Rate for such Interest Period.

     SECTION 4.10.  CONCLUSIVENESS OF STATEMENTS; SURVIVAL OF PROVISIONS.
                    ---------------------------------------------------- 
Demands made by any Bank to the Borrower under Section 4.5 or 4.8 shall be

                     thereunder from the Issuer thereof that an Event of Default
                     has occurred and is continuing.

     By delivery to the Issuer and the Agent of an Issuance Request at least two
but not more than five Business Days prior to the Stated Expiry Date of any
Letter of Credit, the Borrower may request the Issuer to extend the Stated
Expiry Date of such Letter of Credit for an additional period not to exceed the

Termination Date.

     SECTION 5.2.  ISSUANCES AND EXTENSIONS.  Subject to the terms and
                   ------------------------                           
conditions of this Agreement (including Article VIII), the Issuer shall issue

          (a)  for the account of the Issuer, with respect to all Letters of
     Credit, a fronting fee of 0.5% per annum (calculated from and including the

     Stated Expiry Date thereof) on the Stated Amount of all Letters of Credit;
     and

          (b)  for the account of the Banks ratably in accordance with their
     respective Percentages, an issuing fee equal to 2.5% (calculated from and

                                                                --- ----
according to their respective Percentages.  Each Bank shall, to the extent of
its Percentage, be deemed to have irrevocably participated in the issuance of
such Letter of Credit and shall be responsible to reimburse promptly the Issuer
for Reimbursement Obligations which have not been reimbursed by the Borrower in
accordance with Section 5.5, or which have been reimbursed by the Borrower but
                -----------

Bank shall, to the extent of its Percentage, be entitled to receive from the
Issuer a ratable portion of the letter of credit fees received by the Issuer
pursuant to clause (b) of Section 5.3, with respect to each Letter of Credit.
            ----------    -----------

reason Facility A Loans shall not be made to fund any Reimbursement Obligation,
all as provided in Section 5.5 in an amount equal to the amount of any drawing
                   -----------                                                
honored by the Issuer under a Letter of Credit issued by it, or in the event the
Issuer must for any reason return or disgorge such reimbursement, the Issuer
shall promptly notify each Bank of the unreimbursed amount of such drawing and
of such Bank's respective participation therein. Each Bank 
<PAGE>
 
                                     -64-

shall make available to the Issuer, whether or not any Default or Event of
Default shall have occurred and be continuing, an amount equal to its respective
participation in same day or immediately available funds at the office of the
Issuer specified in such notice not later than 12:00 p.m. (Boston time) on the
Business Day after the date notified by the Issuer. In the event that any Bank
fails to make available to such Issuer the amount of such Bank's participation
in such Letter of Credit as provided herein, the Issuer shall be entitled to
recover such amount on demand from such Bank together with interest at the daily
average Federal Funds Rate for three Business Days (together with such other
compensatory amounts as may be required to be paid by such Bank to the Issuer
pursuant to the Rules for Interbank Compensation of the Council on International
Banking or the Clearinghouse Compensation Committee, as the case may be, as in
effect from time to time) and thereafter at the Prime Rate plus 1-1/2%. Nothing
in this Section 5.4 shall be deemed to prejudice the right of any Bank to
        -----------
recover from the Issuer any amounts made available by such Bank to the Issuer
pursuant to this Section 5.4 in the event that it is determined by a court of
                 -----------
competent jurisdiction that the payment with respect to a Letter of Credit by
the Issuer in respect of which payment was made by such Lender constituted gross
negligence or willful misconduct on the part of the Issuer. The Issuer shall
distribute to each other Bank which has paid all amounts payable by it under
this Section with respect to any Letter of Credit issued by the Issuer such
other Bank's Percentage of all payments received by the Issuer from the Borrower
in reimbursement of drawings honored by the Issuer under such Letter of Credit
when such payments are received.

     SECTION 5.5.  DISBURSEMENTS.  The Issuer will notify the Borrower and the
                   -------------

shall be made.  Subject to the terms and provisions of such Letter of Credit,
the Issuer shall make such payment to the beneficiary (or its designee) of such
Letter of Credit.  Prior to 1:00 p.m., Boston time, on the Disbursement Date,
the Borrower will reimburse the Issuer for all amounts which the Issuer has
disbursed under such Letter of Credit issued by it.  To the extent the Issuer is
not reimbursed in full in accordance with the third sentence of this Section
                                                                     -------
5.5, the Reimbursement Obligations in respect of a Letter of Credit shall accrue

the Prime Rate Margin applicable to Facility A Loans, payable on demand.  In the
event the Issuer is not reimbursed by the Borrower on the Disbursement Date, or
if the Issuer must for any reason return or disgorge such reimbursement, the
Banks (including the Issuer) shall fund the Reimbursement Obligations therefor
by making Facility A Loans which are Prime Rate Loans as provided in Section 3.1
                                                                     -----------

being deemed to have given a timely Loan Request therefor for such amount);
provided, however, that for the purpose of determining the availability of the
- --------  -------              
Commitments immediately prior to giving effect to the application of the
proceeds of such Loans, such Reimbursement Obligations shall be deemed not to be
outstanding at such time.

     SECTION 5.6.  REIMBURSEMENT.  The Borrower's Obligations under Section 5.5
                   -------------                                    -----------
to reimburse the Issuer with respect to each Disbursement (including interest
thereon) in respect of Letters of Credit (the "Reimbursement Obligations"), and
                                               -------------------------       
each Bank's obligations to make participation payments in each drawing under
Letters of Credit which have not been reimbursed by the Borrower, shall be
absolute and unconditional under any and all circumstances and irrespective of
any setoff, counterclaim or defense to payment which the Borrower may have or
have had against the Issuer, any Bank or any beneficiary of any Letter of
Credit, including any defense based upon the occurrence of any Default or Event
of Default, any draft, demand or certificate or other document presented under a
Letter of Credit proving to be forged, fraudulent, invalid or insufficient, the
failure of any Disbursement to conform to the terms of the applicable Letter of
Credit (if, in the Issuer's good faith opinion in respect of Letters of Credit,
such Disbursement is determined to be appropriate), or any nonapplication or
misapplication by the beneficiary of the proceeds of such Disbursement, or the
legality, validity, form, regularity or enforceability of such Letter of Credit;
and provided, however, that nothing herein shall adversely affect the right of
    --------  -------                                                         
the Borrower to commence any proceeding against the Issuer for any wrongful
Disbursement made by the Issuer under a Letter of Credit issued by it as a
result of acts or omissions constituting gross negligence or willful misconduct
on the part of the Issuer.

     SECTION 5.7.  DEEMED DISBURSEMENTS.  Upon the occurrence and during the
                   --------------------                                     
continuation of any Event of Default, an amount equal to that portion of Letter
of Credit Outstandings attributable to outstanding and undrawn Letters of Credit
shall, at the option of the Issuer (in the case of Letters of Credit), and
without demand upon or notice to the Borrower, be deemed to have been paid or
disbursed by the Issuer thereof under such Letters of Credit (notwithstanding
that such amount may not in fact have been so paid or disbursed), and, upon
notification by the Issuer, as the case may be, to the Agent and the Borrower of
its Obligations under this Section 5.7, the Borrower shall be immediately
                           -----------                                   
obligated to reimburse the Issuer, as the case may be, the amount deemed to have
been so paid or disbursed by the Issuer. Any amounts so received by the Issuer
from the Borrower pursuant to this Section 5.7 shall be held as collateral 
                                   -----------                 
security for the repayment of the Borrower's Obligations, in connection with the
Letters of Credit issued by the Issuer. At any time when such Letters of Credit
shall terminate and all obligations of the

                                     -66-

Issuer are either terminated or paid or reimbursed to the Issuer in full, the
Obligations of the Borrower under this Section 5.7 shall be reduced accordingly
                                       -----------
(subject, however, to reinstatement in the event any payment in respect of such
 -------  -------
Letters of Credit is recovered in any manner from the Issuer), and the Issuer
will, if no other monetary Obligations are then owed to the Issuer or the Banks
hereunder, return to the Borrower the excess, if any, of

          (a) the aggregate amount deposited by the Borrower with the Issuer and
     not theretofore applied by the Issuer to any Reimbursement Obligations owed
     to the Issuer, over
                    ----

          (b) the aggregate amount of all Reimbursement Obligations owed to the
     Issuer pursuant to this Section, as so adjusted.

If any other monetary Obligations shall be owed by the Borrower or any of its
Subsidiaries to the Issuer or any Bank hereunder, then the Issuer shall turn
over such excess amount to the Agent for application to such Obligations until
the same shall be paid in full.  At such time when all Events of Default shall
have been cured or waived and all of the Borrower's Obligations hereunder shall
have been paid in full, the Issuer or the Agent, as the case may be, shall
return to the Borrower all amounts then on deposit with the Issuer pursuant to
this Section 5.7.  All amounts on deposit pursuant to this Section shall, until
     -----------                                                               
their application to any Reimbursement Obligations or their return to the
Borrower, as the case may be, bear interest at the daily average Federal Funds
Rate from time to time in effect (net of the costs of any reserve requirements,
in respect of amounts on deposit pursuant to this Section, pursuant to F.R.S.
Board Regulation D), which interest shall be held by the Issuer or the Agent, as
the case may be, as additional collateral security for the repayment of the
Borrower's Obligations in connection with the Letters of Credit issued by the
Issuer and the Borrower's other Obligations hereunder or under any Loan
Document.

     SECTION 5.8.  NATURE OF REIMBURSEMENT OBLIGATIONS.  The Borrower shall
                   -----------------------------------                     
assume all risks of the acts, omissions or misuse of any Letter of Credit by the
beneficiary thereof.  Neither the Issuer nor any Bank (except to the extent of
its own gross negligence or willful misconduct) shall be responsible for:

          (a) the form, validity, sufficiency, accuracy, genuineness or legal
     effect of any Letter of Credit or any document submitted by any party in
     connection with the application for and issuance of a Letter of Credit,
     even if it should in fact prove to be in any or all respects invalid,
     insufficient, inaccurate, fraudulent or forged;
<PAGE>
 
                                     -67-

          (b) the form, validity, sufficiency, accuracy, genuineness or legal
     effect of any Instrument transferring or assigning or purporting to
     transfer or assign a Letter of Credit or the rights or benefits thereunder
     or proceeds thereof, in whole or in part, which may prove to be invalid or
     ineffective for any reason;

          (c) the failure of the beneficiary to comply fully with conditions
     required in order to demand payment under a Letter of Credit;

          (d) errors, omissions, interruptions or delays in transmission or
     delivery of any messages, by mail, cable, telegraph, telex or otherwise; or

          (e) any loss or delay in the transmission or otherwise of any document
     or draft required in order to make a Disbursement under a Letter of Credit
     or of the proceeds thereof.

None of the foregoing shall affect, impair or prevent the vesting of any of the
rights or powers granted to the Issuer or any Bank hereunder.  In furtherance
and extension, and not in limitation or derogation of any of the foregoing, any
action taken or omitted to be taken by the Issuer in good faith shall be binding
upon the Borrower and shall not put the Issuer under any resulting liability to
the Borrower.

          SECTION 5.9.  INDEMNITY.  In addition to amounts payable as elsewhere
                        ---------                                              
provided in this Article V or in Article VI, the Borrower hereby agrees to

protect, indemnify, pay and save the Issuer and each Bank participating in any
Letter of Credit harmless from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees) which the Issuer or such Bank participating in such Letter of
Credit may incur or be subject to as a consequence, direct or indirect, of (a)
the issuance of any Letter of Credit, other than as a result of the gross
negligence or willful misconduct of the Issuer or such Bank participating in
such Letter of Credit as determined by a court of competent jurisdiction, or (b)
the failure of the Issuer or such Bank participating in such Letter of Credit to
honor a drawing under any Letter of Credit issued by it as a result of any act
or omission, whether rightful or wrongful, of any present or future de jure or
                                                                    -- ----

     SECTION 6.1.  GUARANTY.
                   -------- 

     SECTION 6.1.1.  GUARANTY OF PAYMENT.  Each of the Principal Companies (in

absolutely, unconditionally and irrevocably guaranties to the Secured Parties
the full and punctual payment when due, whether at stated maturity, by scheduled

11 U.S.C. 362(a)), of each of the Obligations, in accordance with its terms,
whether such Obligations are outstanding on the date of this Agreement or arise
or are incurred at any time or times thereafter. The Guaranties hereby made
constitute guaranties of payment when due and not of collection, and each of the
Guarantors individually agrees that it shall not be necessary or required that
any Secured Party exercise any rights, assert any claim or demand or enforce any
remedy whatsoever against any Principal Company before or as a condition to the
obligations of the Guarantors hereunder. The liabilities and obligations of each
of the Guarantors to the Secured Parties under its respective Guaranty made
hereunder shall be unlimited, and such liabilities and obligations are joint and

obligations are absolute and unconditional, but as a separate undertaking on the
part of the Guarantors, each of the Guarantors hereby absolutely,
unconditionally and irrevocably, and jointly and severally, covenants and agrees
to cause each of the other Principal Companies to perform and comply with all of
the covenants, agreements and conditions to be complied with by any such
Principal Company under the Loan Documents, and each of the Guarantors hereby
agrees, jointly and severally, to take or to cause to be taken, promptly and
without any expense to the Secured Parties, all such measures as may be
appropriate and can be lawfully effected by such Guarantor to prevent the
occurrence of any Default and to cure or make good promptly any Default which
may occur at any time or times.

     SECTION 6.2.  GUARANTY ABSOLUTE.  The obligations of the Guarantors under

will be paid strictly in accordance with the terms of this Agreement and the
other Loan Documents, regardless of any Applicable Law now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of the
Secured Parties with respect thereto.  The liabilities and obligations of the
Guarantors under the Guaranties hereby made shall be absolute, unconditional and
irrevocable, and also joint and several, irrespective of:

               (a) any lack of validity or enforceability of this Agreement or
     any other Loan Document or any other agreement or Instrument relating to
     any thereof or to any of the Obligations;

               (b) any change in the corporate existence, structure or ownership
     of any of the Principal Companies or their Subsidiaries, or any insolvency,
     bankruptcy, reorganization or other similar proceeding affecting any such
     Person or any Property of any such Person or any resulting release or
     discharge of any Obligation contained in this Agreement or any other Loan
     Document;

               (c)  the failure of any Secured Party

                    (i)  to assert any claim or demand or to enforce any right
               or remedy against the Borrower, any other Guarantor, or any other
               Person under the provisions of this Agreement or any other Loan
               Document or any other agreement or Instrument relating to any
               thereof or under any Applicable Law, or

                    (ii) to exercise any right or remedy against any Collateral;

               (d) any change in the time, manner or place of payment of, or in
     any other term of, all or any of the Obligations, or any other compromise,
     renewal, extension, acceleration or release with respect thereto or with
     respect to the Collateral, or any other amendment to, rescission, waiver or
     other modification of, or any consent to departure from, any of the terms
     of this Agreement or any other Loan Document or any other Instrument
     relating to any thereof;

               (e) any increase, reduction, limitation, impairment or
     termination of any of the Obligations for any reason, including any claim
     of waiver, release, surrender, alteration or compromise, and any defense or
     set-off, counterclaim, recoupment or termination whatsoever by reason of
     the invalidity, illegality, nongenuineness,

     any amendment to or waiver or release of, or consent to departure from, any
     other guaranties held by any Secured Party securing all or any of the
     Obligations;

               (g) any defense, set-off or counterclaim which may at any time be
     available to or be asserted by the Borrower or any other Principal Company
     against any other Principal Company or against the Agent; or

               (h) any other circumstance which might otherwise constitute a
     suretyship or other defense available to, or a legal or equitable discharge
     of, the Borrower or any other Guarantor.

     SECTION 6.3.  REINSTATEMENT, ETC.  The Guarantors agree that the Guaranties
                   ------------------                                
hereby made shall continue to be effective or be reinstated, as the case may be,
if at any time any payment (in whole or in part) of any of the Obligations is
rescinded or must otherwise be restored by the Agent upon the insolvency,
bankruptcy or reorganization of the Borrower or otherwise, all as though such
payment had not been made.

     SECTION 6.4.  WAIVER.  Each of the Guarantors hereby waives promptness,
                   ------                                       
diligence, notice of acceptance and any other notice with respect to any of the
Obligations or its Guaranty and any requirement that any Secured Party protect,
secure, perfect or insure any Lien or any Property subject thereto or exhaust
any right or take any action against the Borrower, the other Guarantors, or any
other Person or entity or any Collateral.

     SECTION 6.5.  SUBORDINATION OF SUBROGATION RIGHTS.  The rights which any

collectively called the "Subrogation Rights."  In the event of any proceeding
                         ------------------                                  
for the distribution, division or application of all or any part of the Property
of any of the other Principal Companies, whether such proceeding be for the
liquidation, dissolution or winding up of any of the other Principal Companies,
a receivership, insolvency or bankruptcy proceeding, an assignment for the
benefit of creditors, or a proceeding by or against any of the other Principal
Companies for relief under any bankruptcy, reorganization or insolvency law, if
all of the Obligations have not been paid and satisfied in full at the

proceeding:

               (a) to enforce all of the Subrogation Rights of such Guarantor,
     in the name of the Agent or in the name of such Guarantor, by proof of
     debt, proof of claim, suit or otherwise;

               (b) to collect any Property of any of the other Principal
     Companies distributed or applied by way of dividend or payment on account
     of such Subrogation Rights, and to apply the same, or the proceeds of any
     realization thereof, towards the payment of the Obligations until all the
     Obligations have been paid and satisfied in full in cash; and

               (c) to vote all claims arising under or in respect of all such
     Subrogation Rights.

          So long as any Obligations remain unpaid, no Guarantor shall take any
action of any kind to enforce any of its Subrogation Rights, and no Guarantor
shall receive or accept from any Person any payments or other distributions in
respect of any of its Subrogation Rights.  Should any payment on account of any
of the Subrogation Rights be received by any Guarantor, such payment shall be
delivered by such Guarantor forthwith to the Agent for the benefit of the
Secured Parties in the form received by such Guarantor, except for the addition
of any endorsement or assignment necessary to effect transfer of all rights
therein to the Agent.  Until so delivered, each such payment shall be held by
such Guarantor in trust for the benefit of the Secured Parties and shall not be
commingled with any other funds of such Guarantor.

exercising or not exercising from time to time any rights and privileges
available to it under this Agreement, the Notes or the other Loan Documents.

     SECTION 11.7.  NOTICES, ETC., TO THE AGENT.  The Agent will distribute

2.     Exercise.
       -------- 

       (a) This Warrant may be exercised by the Holder, in whole or in part, by
surrendering this Warrant, with the purchase form appended hereto as Exhibit
                                                                     -------
A, duly executed by such Holder, at the principal office of the Company, or at
- -
such other office or agency as the Company may designate, accompanied by payment
in full by bank or certified check in lawful money of the United States, of the
aggregate Purchase Price payable in respect of the total number of shares of
Common Stock purchased upon such exercise.

       (b) Each exercise of this Warrant shall be deemed to have been effected
immediately prior to the close of business on the day on which this Warrant
shall have been surrendered to the Company as provided in Subsection 2(a) above.
                                                          ---------------    
At such time, the person or persons in whose name or names any certificates for
or other instruments evidencing shares of Common Stock shall be issuable upon
such exercise as provided in Subsection 2(d) below shall be deemed to have
                             ---------------                              
become the holder or holders of record of the Common Stock represented by such
certificates or other instruments.

     (c)    (i)  The Holder may at its sole option, and in lieu of paying the
          Purchase Price pursuant to Subsection 2(a) hereof, exchange this
                                     ---------------                      
          Warrant in whole or in part for a number of shares of Common Stock as
          determined below.  Such shares of Common Stock shall be issued by the
          Company to the Holder without payment by the Holder of any other
          exercise price or any cash or other consideration.  The number of
          shares of Common Stock to be so issued to the Holder shall be equal to
          the quotient obtained by dividing (A) the Surrendered Value (as
          defined below) on the date of surrender of this Warrant pursuant to
          Subsection 2(a), by (B) the Fair Market Value on the exchange date of
          ---------------                                                      
          one share of Common Stock.

            (ii) For the purposes of this Subsection 2(c), the "Surrendered
                                          ---------------       -----------
          Value" of a portion of this Warrant on a given date shall be deemed to
          -----                                                                 
          be the excess of (A) the aggregate Fair Market Value on such date of
          the total number of shares of Common Stock otherwise issuable upon
          exercise of such portion of the Warrant, over (B) the aggregate
                                                   ----                  
          Purchase Price of such total number of shares of Common Stock.

     (d) As soon as practicable after the exercise of this Warrant in full or in
part, and in any event within three (3) business days thereafter, the Company,
at its expense, will cause to be issued in the name of, and delivered to, the
Holder, or, subject to the terms and conditions hereof, as such Holder (upon
payment by such Holder of any applicable transfer taxes) may direct:
<PAGE>
 
                                      3
 
               (i) a certificate or certificates for the number of full shares
          of Common Stock to which such Holder shall be entitled upon such
          exercise, plus, in lieu of any fractional share to which such Holder
                    ----                                                      
          would otherwise be entitled, cash in an amount determined pursuant to
          Section 3 hereof, and
          ---------            

               (ii) in case such exercise is in part only, a new warrant or
          warrants (dated the date hereof) of like tenor, calling in the
          aggregate on the face or faces thereof for the number of shares of
          Common Stock equal (without giving effect to any adjustment therein)
          to the Warrant Number minus the number of such shares of Common Stock
          purchased by the Holder upon such exercise.

3.   Adjustments; Fractional Securities.
     ---------------------------------- 

     (a) If, at any time after the original issue date of this Warrant, the
outstanding Common Stock shall be subdivided into a greater number of shares or
a dividend in Common Stock shall be paid in respect of Common Stock, the
Purchase Price in effect immediately prior to such subdivision or at the record
date of such dividend shall simultaneously with the effectiveness of such
subdivision or immediately after the record date of such dividend be immediately
and automatically proportionately and equitably reduced.  If, at any time after
the original issue date of this Warrant, the outstanding Common Stock shall be
combined into a smaller number of shares, the Purchase Price in effect
immediately prior to such combination shall, simultaneously with the
effectiveness of such combination, be immediately and automatically
proportionately and equitably increased.  When any adjustment is required to be
made in the Purchase Price, the number of shares of Common Stock purchasable
upon the exercise of this Warrant shall be changed to the number determined by
dividing (i) an amount equal to the maximum number of shares of Common Stock
issuable upon the exercise of this Warrant immediately prior to such adjustment,
multiplied by the Purchase Price in effect immediately prior to such adjustment,
by (ii) the Purchase Price in effect immediately after such adjustment.

     (b) If, at any time after the original issue date of this Warrant, there
shall occur any capital reorganization or reclassification of the Common Stock
(other than a change in par value or a subdivision or combination as provided
for in Subsection 3(a) above), or any consolidation or merger of the Company
       ---------------                                                      
with or into another corporation, or a transfer of all or substantially all of
the assets of the Company, or the payment of a liquidating distribution, then,
as part of any such reorganization, reclassification, consolidation, merger,
sale, automatic conversion or liquidating distribution, lawful provision shall
be made so that the Holder of this Warrant shall have the right thereafter to
receive upon the exercise hereof (to the extent, if any, still exercisable) the
kind and amount of shares of stock or other securities or property which such
Holder would have been entitled to receive if, immediately prior to any such
reorganization, reclassification, consolidation, merger, sale, automatic
conversion or liquidating distribution, as the case may be, such Holder had held
the number of shares of Common Stock which were then purchasable upon the
exercise of this Warrant.  In any such case, appropriate adjustment (as
reasonably determined by the Board of Directors 
<PAGE>
 
                                       4

of the Company) shall be made in the application of the provisions set forth
herein with respect to the rights and interests thereafter of the Holder of this
Warrant such that the provisions set forth in this Section 3 (including
                                                   ---------  
provisions with respect to adjustment of the Purchase Price) shall thereafter be
applicable, as nearly as is reasonably practicable, in relation to any shares of
stock or other securities or property thereafter deliverable upon the exercise
of this Warrant.

     (c) In any case in which this Section 3 shall require that any adjustment
                                   ---------                                  
in the number of shares of Common Stock or other property for which this Warrant
may be exercised be made effective as of a record date for a specified event,
the Company may elect to defer until the occurrence of such event the issuing to
the Holder with respect to the exercise of this Warrant after that record date
the Common Stock and other property, if any, issuable upon exercise over and
above the Common Stock and other property, if any, issuable upon exercise of
this Warrant as in effect prior to such adjustment; provided, however, that,
                                                    --------  -------       
upon request, the Company shall deliver to the Holder a due bill or other
appropriate instrument evidencing the Holder's right to receive such additional
shares or property upon the occurrence of the event requiring such adjustment.

     (d) When any adjustment is required to be made in the Purchase Price or the
Warrant Number, the Company shall promptly mail to the Holder a certificate
setting forth the Purchase Price and the Warrant Number after such adjustment,
and setting forth a brief statement of the facts requiring such adjustment.
Such certificate shall also set forth the kind and amount of stock or other
securities or property into which this Warrant shall be exercisable following
the occurrence of any of the events specified in Subsection 3(a), (b) or (c)
                                                 ---------------  ---    ---
above.

     (e) The Company shall not be required, upon the exercise of this Warrant,
to issue any fractional shares, but shall make an adjustment therefore in cash
on the basis of the Fair Market Value of the Common Stock at the time of
exercise.

4.   Limitation on Sales, etc.
     ------------------------ 

     The Holder, and each subsequent holder of this Warrant, if any,
acknowledges that this Warrant and the underlying shares of Common Stock have
not been registered under the Securities Act of 1933, as now in force or
hereafter amended, or any successor legislation (the "Act"), and agrees not to
                                                      ---                     
sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this
Warrant or any Common Stock issued upon its exercise in the absence of (a) an
effective registration statement under the Act as to this Warrant or such
underlying shares of Common Stock and registration or qualification of this
Warrant or such underlying shares of Common Stock under any applicable Blue Sky
or state securities laws then in effect, or (b) an opinion of counsel,
satisfactory to the Company, that such registration and qualification are not
required.

     Without limiting the generality of the foregoing, unless the offering and
sale of the Common Stock to be issued upon the particular exercise of the
Warrant shall have been effectively registered under the Act, the Company shall
be under no obligation to issue the shares covered by such exercise unless and
until the registered Holder shall 
<PAGE>
 
                                       5

have executed an investment letter in form and substance reasonably satisfactory
to the Company, including a warranty at the time of such exercise that it is
acquiring such shares for its own account, for investment, and not with a view
to, or for sale in connection with, the distribution of any such shares, in
which event the registered Holder shall be bound by the provisions of a legend
to such effect on the certificate(s) representing the Common Stock.

     In addition, without limiting the generality of the foregoing, the Company
may delay issuance of the Common Stock hereunder until completion of any action
or obtaining of any consent which the Company deems necessary under any
applicable law (including without limitation state securities or "blue sky"
laws), provided that the Company shall use all reasonable efforts in good faith
       --------                                                                
to diligently pursue completion of such action or the receipt of such consent.

5.   Notices of Record Date, etc.
     --------------------------- 

     In case:

     (a) the Company shall take a record of the holders of Common Stock for the
purpose of entitling or enabling them to receive any dividend or other
distribution, or to receive any right to subscribe for or purchase any shares of
stock of any class or any other securities, or to receive any other right, or

     (b) of any capital reorganization of the Company, any reclassification of
the capital stock of the Company, any consolidation or merger of the Company
with or into another corporation, or any transfer of all or substantially all of
the assets of the Company, or

     (c) of the voluntary or involuntary dissolution, liquidation or winding-up
of the Company,

then, and in each such case, the Company will mail or cause to be mailed to the
Holder of this Warrant a notice specifying, as the case may be, (i) the date on
which a record is to be taken for the purpose of such dividend, distribution or
right, and stating the amount and character of such dividend, distribution or
right, or (ii) the effective date on which such reorganization,
reclassification, consolidation, merger, transfer, 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 Common Stock shall be entitled to exchange their Common
Stock for securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation or
winding-up.  Such notice shall be mailed at least twenty (20) days prior to the
record date or effective date for the event specified in such notice, provided
                                                                      --------
that the failure to so mail such notice shall not affect the legality or
validity of any such action.

                                       6

6.   Reservation of Stock, etc.

issuance and delivery upon the exercise of this Warrant, such stock and other
property as from time to time shall be issuable upon the exercise of this
Warrant.

     (b) The Company will not, by amendment of its Certificate of Incorporation
or through reorganization, consolidation, merger, dissolution, issuance of
capital stock or sale of treasury stock (otherwise than upon exercise of this
Warrant) or sale of assets, or by any other act or deed, avoid or seek to avoid
the material performance or observance of any of the covenants, stipulations or
conditions in this Warrant to be observed or performed by the Company.  The
Company will at all times in good faith assist, insofar as it is able, in the
carrying out of all of the provisions of this Warrant in a reasonable manner and
in the taking of all other action which may be necessary in order to protect the
rights hereunder of the Holder of this Warrant.

     (c) The Company will maintain an office where presentations and demands to
or upon the Company in respect of this Warrant may be made.  The Company will
give notice in writing to the Holder, at the address of the Holder appearing on
the books of the Company, of each change in the location of such office.

8.   Transfers, etc.

     (a) The Company will maintain a register containing the names and addresses
of the Holders of this Warrant.  The Holder may change its, his or her address
as shown on the warrant register by written notice to the Company requesting

Company may treat the Holder of this Warrant as the absolute owner hereof for
all purposes.

9.   Replacement of Warrants.

loss, theft, destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) upon delivery of an indemnity agreement (with surety
if reasonably required) in an amount reasonably satisfactory to the Company, or
(in the case of mutilation) upon surrender and cancellation of this Warrant, the
Company will issue, in lieu thereof, a new Warrant of like tenor.

2.     Exercise.
       -------- 

       (a) This Warrant may be exercised by the Holder, in whole or in part, by
surrendering this Warrant, with the purchase form appended hereto as Exhibit
                                                                     -------
A, duly executed by such Holder, at the principal office of the Company, or at
- -
such other office or agency as the Company may designate, accompanied by payment
in full by bank or certified check in lawful money of the United States, of the
aggregate Purchase Price payable in respect of the total number of shares of
Common Stock purchased upon such exercise.

       (b) Each exercise of this Warrant shall be deemed to have been effected
immediately prior to the close of business on the day on which this Warrant
shall have been surrendered to the Company as provided in Subsection 2(a) above.
                                                          ---------------   
At such time, the person or persons in whose name or names any certificates for
or other instruments evidencing shares of Common Stock shall be issuable upon
such exercise as provided in Subsection 2(d) below shall be deemed to have
                             ---------------                              
become the holder or holders of record of the Common Stock represented by such
certificates or other instruments.

       (c)    (i)  The Holder may at its sole option, and in lieu of paying the
          Purchase Price pursuant to Subsection 2(a) hereof, exchange this
                                     ---------------                      
          Warrant in whole or in part for a number of shares of Common Stock as
          determined below.  Such shares of Common Stock shall be issued by the
          Company to the Holder without payment by the Holder of any other
          exercise price or any cash or other consideration.  The number of
          shares of Common Stock to be so issued to the Holder shall be equal to
          the quotient obtained by dividing (A) the Surrendered Value (as
          defined below) on the date of surrender of this Warrant pursuant to
          Subsection 2(a), by (B) the Fair Market Value on the exchange date of
          ---------------                                                      
          one share of Common Stock.

            (ii) For the purposes of this Subsection 2(c), the "Surrendered
                                          ---------------       -----------
          Value" of a portion of this Warrant on a given date shall be deemed to
          -----                                                                 
          be the excess of (A) the aggregate Fair Market Value on such date of
          the total number of shares of Common Stock otherwise issuable upon
          exercise of such portion of the Warrant, over (B) the aggregate
                                                   ----                  
          Purchase Price of such total number of shares of Common Stock.

       (d) As soon as practicable after the exercise of this Warrant in full 
or in part, and in any event within three (3) business days thereafter, the
Company, at its expense, will cause to be issued in the name of, and delivered
to, the Holder, or, subject to the terms and conditions hereof, as such Holder
(upon payment by such Holder of any applicable transfer taxes) may direct:
<PAGE>
 
                                       3

               (i) a certificate or certificates for the number of full shares
          of Common Stock to which such Holder shall be entitled upon such
          exercise, plus, in lieu of any fractional share to which such Holder
                    ----                                                      
          would otherwise be entitled, cash in an amount determined pursuant to
          Section 3 hereof, and
          ---------            

               (ii) in case such exercise is in part only, a new warrant or
          warrants (dated the date hereof) of like tenor, calling in the
          aggregate on the face or faces thereof for the number of shares of
          Common Stock equal (without giving effect to any adjustment therein)
          to the Warrant Number minus the number of such shares of Common Stock
          purchased by the Holder upon such exercise.

3.   Adjustments; Fractional Securities.
     ---------------------------------- 

     (a) If, at any time after the original issue date of this Warrant, the
outstanding Common Stock shall be subdivided into a greater number of shares or
a dividend in Common Stock shall be paid in respect of Common Stock, the
Purchase Price in effect immediately prior to such subdivision or at the record
date of such dividend shall simultaneously with the effectiveness of such
subdivision or immediately after the record date of such dividend be immediately
and automatically proportionately and equitably reduced.  If, at any time after
the original issue date of this Warrant, the outstanding Common Stock shall be
combined into a smaller number of shares, the Purchase Price in effect
immediately prior to such combination shall, simultaneously with the
effectiveness of such combination, be immediately and automatically
proportionately and equitably increased.  When any adjustment is required to be
made in the Purchase Price, the number of shares of Common Stock purchasable
upon the exercise of this Warrant shall be changed to the number determined by
dividing (i) an amount equal to the maximum number of shares of Common Stock
issuable upon the exercise of this Warrant immediately prior to such adjustment,
multiplied by the Purchase Price in effect immediately prior to such adjustment,
by (ii) the Purchase Price in effect immediately after such adjustment.

     (b) If, at any time after the original issue date of this Warrant, there
shall occur any capital reorganization or reclassification of the Common Stock
(other than a change in par value or a subdivision or combination as provided
for in Subsection 3(a) above), or any consolidation or merger of the Company
       ---------------                                                      
with or into another corporation, or a transfer of all or substantially all of
the assets of the Company, or the payment of a liquidating distribution, then,
as part of any such reorganization, reclassification, consolidation, merger,
sale, automatic conversion or liquidating distribution, lawful provision shall
be made so that the Holder of this Warrant shall have the right thereafter to
receive upon the exercise hereof (to the extent, if any, still exercisable) the
kind and amount of shares of stock or other securities or property which such
Holder would have been entitled to receive if, immediately prior to any such
reorganization, reclassification, consolidation, merger, sale, automatic
conversion or liquidating distribution, as the case may be, such Holder had held
the number of shares of Common Stock which were then purchasable upon the
exercise of this Warrant.  In any such case, appropriate adjustment (as
reasonably determined by the Board of Directors 
<PAGE>
 
                                       4

of the Company) shall be made in the application of the provisions set forth
herein with respect to the rights and interests thereafter of the Holder of this
Warrant such that the provisions set forth in this Section 3 (including
                                                   ---------  
provisions with respect to adjustment of the Purchase Price) shall thereafter be
applicable, as nearly as is reasonably practicable, in relation to any shares of
stock or other securities or property thereafter deliverable upon the exercise
of this Warrant.

     (c) In any case in which this Section 3 shall require that any adjustment
                                   ---------                                  
in the number of shares of Common Stock or other property for which this Warrant
may be exercised be made effective as of a record date for a specified event,
the Company may elect to defer until the occurrence of such event the issuing to
the Holder with respect to the exercise of this Warrant after that record date
the Common Stock and other property, if any, issuable upon exercise over and
above the Common Stock and other property, if any, issuable upon exercise of
this Warrant as in effect prior to such adjustment; provided, however, that,
                                                    --------  -------       
upon request, the Company shall deliver to the Holder a due bill or other
appropriate instrument evidencing the Holder's right to receive such additional
shares or property upon the occurrence of the event requiring such adjustment.

     (d) When any adjustment is required to be made in the Purchase Price or the
Warrant Number, the Company shall promptly mail to the Holder a certificate
setting forth the Purchase Price and the Warrant Number after such adjustment,
and setting forth a brief statement of the facts requiring such adjustment.
Such certificate shall also set forth the kind and amount of stock or other
securities or property into which this Warrant shall be exercisable following
the occurrence of any of the events specified in Subsection 3(a), (b) or (c)
                                                 ---------------  ---    ---
above.

     (e) The Company shall not be required, upon the exercise of this Warrant,
to issue any fractional shares, but shall make an adjustment therefore in cash
on the basis of the Fair Market Value of the Common Stock at the time of
exercise.

4.   Limitation on Sales, etc.
     ------------------------ 

     The Holder, and each subsequent holder of this Warrant, if any,
acknowledges that this Warrant and the underlying shares of Common Stock have
not been registered under the Securities Act of 1933, as now in force or
hereafter amended, or any successor legislation (the "Act"), and agrees not to
                                                      ---                     
sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this
Warrant or any Common Stock issued upon its exercise in the absence of (a) an
effective registration statement under the Act as to this Warrant or such
underlying shares of Common Stock and registration or qualification of this
Warrant or such underlying shares of Common Stock under any applicable Blue Sky
or state securities laws then in effect, or (b) an opinion of counsel,
satisfactory to the Company, that such registration and qualification are not
required.

     Without limiting the generality of the foregoing, unless the offering and
sale of the Common Stock to be issued upon the particular exercise of the
Warrant shall have been effectively registered under the Act, the Company shall
be under no obligation to issue the shares covered by such exercise unless and
until the registered Holder shall 
<PAGE>
 
                                       5

have executed an investment letter in form and substance reasonably satisfactory
to the Company, including a warranty at the time of such exercise that it is
acquiring such shares for its own account, for investment, and not with a view
to, or for sale in connection with, the distribution of any such shares, in
which event the registered Holder shall be bound by the provisions of a legend
to such effect on the certificate(s) representing the Common Stock.

     In addition, without limiting the generality of the foregoing, the Company
may delay issuance of the Common Stock hereunder until completion of any action
or obtaining of any consent which the Company deems necessary under any
applicable law (including without limitation state securities or "blue sky"
laws), provided that the Company shall use all reasonable efforts in good faith
       --------                                                                
to diligently pursue completion of such action or the receipt of such consent.

5.   Notices of Record Date, etc.
     --------------------------- 

     In case:

     (a) the Company shall take a record of the holders of Common Stock for the
purpose of entitling or enabling them to receive any dividend or other
distribution, or to receive any right to subscribe for or purchase any shares of
stock of any class or any other securities, or to receive any other right, or

     (b) of any capital reorganization of the Company, any reclassification of
the capital stock of the Company, any consolidation or merger of the Company
with or into another corporation, or any transfer of all or substantially all of
the assets of the Company, or

     (c) of the voluntary or involuntary dissolution, liquidation or winding-up
of the Company,

then, and in each such case, the Company will mail or cause to be mailed to the
Holder of this Warrant a notice specifying, as the case may be, (i) the date on
which a record is to be taken for the purpose of such dividend, distribution or
right, and stating the amount and character of such dividend, distribution or
right, or (ii) the effective date on which such reorganization,
reclassification, consolidation, merger, transfer, 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 Common Stock shall be entitled to exchange their Common
Stock for securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation or
winding-up. Such notice shall be mailed at least twenty (20) days prior to the
record date or effective date for the event specified in such notice, provided
                                                                      --------
that the failure to so mail such notice shall not affect the legality or
validity of any such action.

Warrant.

Warrant) or sale of assets, or by any other act or deed, avoid or seek to avoid
the material performance or observance of any of the covenants, stipulations or
conditions in this Warrant to be observed or performed by the Company.  The
Company will at all times in good faith assist, insofar as it is able, in the
carrying out of all of the provisions of this Warrant in a reasonable manner and

FOR IMMEDIATE RELEASE

 VIEW TECH ANNOUNCES NEW $15 MILLION CREDIT FACILITY COMMITMENT FROM IMPERIAL
                              BANK AND BANKBOSTON

      - Vermont Telecommunications Network Services Acquisition Closes -

CAMARILLO, CA - December 3, 1997 - View Tech, Inc. (Nasdaq:  VUTK) today
announced that Imperial Bank of Los Angeles, California and BankBoston, N.A. of
Boston, Massachusetts will provide View Tech with a $15 million credit facility.
In addition, the Company announced that the receipt of this credit facility has
accommodated View Tech's recently announced agreement to acquire Vermont
Telecommunications Network Services, Inc. ("Network Services"; release dated
November 13), and the acquisition has been closed.

"This credit facility will help to provide View Tech with the financial
flexibility to continue its growth, especially by means of acquisition," said
Paul C. O'Brien, View Tech's chairman of the board.  "We are particularly
pleased that the Network Services acquisition has closed successfully, enabling
View Tech to bring its high-quality communications solutions to more businesses
in the Northeast."

The $15 million credit facility will be underwritten primarily by Imperial Bank,
which will provide $9 million of the total financing.  BankBoston, N.A. will
provide the remaining $6 million.  This financing includes funds to be used for
acquisitions, general corporate expenditures, and working capital.

"We believe the commitment from Imperial Bank and BankBoston is an
acknowledgment of View Tech's strengths as a business, and we look forward to a
successful, long-term banking relationship," said Robert G. Hatfield, chief
executive officer of View Tech.  "View Tech has taken many steps recently to
bring us closer to becoming a national leader in our very competitive market,
and we continue to strive for that goal."
