         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS FOR THE PERIOD ENDED
                                  JUNE 30, 1997


a) Vodavi  Technology,  Inc. (the  Company),  a Delaware  corporation,  designs,
develops,  markets,  and supports a broad range of  telecommunications  systems,
commercial grade telephones,  computer-telephony  products, and voice processing
products,  including voice mail, fax mail, Internet  messaging,  and interactive
voice response systems, for a wide variety of commercial applications.

(b) The  accompanying  unaudited  consolidated  financial  statements  have been
prepared by the Company without audit,  pursuant to the rules and regulations of
the Securities and Exchange  Commission.  These financial statements reflect all
adjustments (consisting of normal recurring accruals and adjustments) which are,
in the opinion of management,  necessary to fairly state the financial  position
as of June 30,  1997 and the  operating  results  and cash flows for the periods
presented.   Operating  results  for  the  interim  periods  presented  are  not
necessarily  indicative  of the  operating  results that may be expected for the
entire year. These financial  statements  should be read in conjunction with the
Company's December 31, 1996 financial statements and accompanying notes thereto.

(c) In the fourth quarter of 1996, certain events occurred which resulted in the
Company  recording an impairment  loss related to the goodwill  associated  with
Enhanced  Systems,  Inc.  (Enhanced).  See  footnotes  1 and 4 to the  Company's
financial statements for the year ended December 31, 1996.

(d) Net  income  per share for the  periods  ended  June 30,  1997 and 1996 were
determined by dividing net income by the weighted  average  number of common and
common equivalent shares outstanding.

         In February  1997,  the  Financial  Accounting  Standards  Board issued
Statement of Financial Accounting Standard (SFAS) No. 128, "Earnings Per Share."
The new standard  requires dual  presentation of both basic and diluted earnings
per  share  ("EPS")  on the  face  of the  earnings  statement  and  requires  a
reconciliation  of both basic and diluted EPS  calculations.  This  statement is
effective for financial  statements  for both interim and annual  periods ending
after December 15, 1997. This statement will be effective for the Company's 1997
fiscal year. EPS as reported in this Form 10-Q would not be materially different
under the provisions of SFAS No. 128.

         Revenue

Revenue remained  relatively constant at approximately $11.9 million in both the
second quarters of 1997 and 1996.

         Gross Margin

Gross margin remained  relatively  constant at approximately 33.3% of revenue in
the second quarter of 1997 as compared with 33.5% in the second quarter of 1996.

         Engineering and Product Development

Expenditures  related to engineering and product development declined $36,000 in
the second quarter of 1997 as compared with the second quarter of 1996.

         Selling, General and Administrative

Selling,  general and  administrative  expenses  declined $152,000 in the second
quarter of 1997 as compared with the second  quarter of 1996. As a percentage of
revenue,  selling,  general  and  administrative  expenses  declined to 23.0% of
revenue  in the  second  quarter  of 1997 as  compared  with 24.3% in the second
quarter of 1996. The  recognition of the impairment  loss related to Enhanced in
the fourth  quarter of 1996 has  eliminated  ongoing  goodwill  amortization  of
approximately $115,000 per quarter.

         Interest Expense

Interest  expense was  approximately  $161,000 in the second  quarter of 1996, a
decrease of $46,000,  or 22.2%, over the second quarter of 1996. The decrease is
attributable  to a decrease in average  borrowings and the effect of the reduced
interest rate in the Company's  new credit  facility (see  Liquidity and Capital
Resources).

         Income Taxes

The Company has provided  for income  taxes using an effective  rate of 39.6% in
the  second  quarter of 1997.  The  provision  for  income  taxes for the second
quarter  of  1996  reflects  the  impact  of  the  non-tax  deductible  goodwill
amortization related to Enhanced.

         Revenue

increase of $1.2 million, or 5.3%, over the first six months of 1996.

         Gross Margin

Gross margin remained  relatively constant at 33.6% of revenue for the first six
months of 1997 as compared with 33.3% in the first six months of 1996.

         Engineering and Product Development

Expenditures  related to engineering and product development declined $53,000 in

         Selling, General and Administrative

Selling,  general and administrative expenses declined $125,000 in the first six
months of 1997 as compared with the first six months of 1996. As a percentage of
revenue,  selling,  general  and  administrative  expenses  declined to 23.6% of

         Interest Expenses

Interest expense was  approximately  $338,000 in the first six months of 1997, a
decrease of $104,000 or 23.5% over the first six months of 1996. The decrease is

         Income Taxes

The Company has provided  for income  taxes using an effective  rate of 39.6% in
the first six months of 1997.  The  provision for income taxes for the first six
months  of  1996  reflects  the  impact  of  the  non-tax  deductible   goodwill
amortization related to Enhanced.


Liquidity and Capital Resources

The Company's cash and cash equivalents were  approximately  1.8 million at June
30, 1997 as compared with $1.2 million at December 31, 1996.  The Company's cash
accounts are swept  regularly and applied  against the Company's line of credit.
The  Company's  borrowings  against its available  operating  line of credit (as
described  below)  at June 30,  1997  were  approximately  $6.7  million,  which
represents  a $1.3  million  increase  from its  borrowings  of $5.4  million at
December 31, 1996. The increased  borrowings are attributed to the timing of the
regular  cash  account  sweeps  by the  Company's  lender  as  evidenced  in the
increased  cash and cash  equivalents  at June 30, 1997 as well as  increases in
overall working capital.  At June 30, 1997, the Company had  approximately  $2.9
million available to it under its operating line of credit.

The Company  maintains a $12.0  million  line of credit  with  General  Electric
Capital Corporation (GE Capital). During the second quarter of 1997, the Company
signed an agreement to extend the facility  through April 2000. The terms of the
extension  lowered the interest  rate to 2.5% over the 30-day  commercial  paper
rate, or a total of 8.1% at June 30, 1997.

Advances  under the line of credit are based upon the  accounts  receivable  and
inventories of Vodavi Communications Systems (VCS), a wholly owned subsidiary of
the Company,  and are secured by substantially all of the assets of the Company.
The revolving line of credit  contains  covenants that are customary for similar
credit facilities and also prohibits the Company's  operating  subsidiaries from
paying  dividends to the Company without the consent of GE Capital.  The Company
was in compliance with the covenants at June 30, 1997.

As of June 30, 1997, the Company has financed  approximately $800,000 in capital
expenditures with vendors and third-party leasing companies.  The terms of these
financings generally provided for interest rates ranging from 9% to 13% with 24-
month repayment periods.

As of June 30, 1997,  the Company had  commitments  in  connection  with its new
product developments.  Such commitments aggregate approximately $100,000 and are
payable  through  December  31,  1997.  The  commitments   include  payments  in
connection with the development of the Company's wireless product.

The Company  believes  that its working  capital and credit  facilities  will be
sufficient to finance its internal growth for the foreseeable  future.  Although
the Company  currently  has no  acquisition  targets,  it intends to continue to
explore  acquisition  opportunities  as they arise and may be  required  to seek
additional financing in the future to meet such opportunities.

                           PART II - OTHER INFORMATION

Item 1.           LEGAL PROCEEDINGS

On September  20, 1996,  the Company and Enhanced  filed a lawsuit in the United
States  District  Court for the  District of Arizona  (No.  CIV 96-2184 PHX SMM)
against Michael Mittel and Fereydoun  Taslimi,  former officers and directors of
Enhanced.  The lawsuit  alleges,  among other  things,  that Messrs.  Mittel and
Taslimi violated  federal and Arizona  securities laws and engaged in fraudulent
activities in connection  with the  Company's  acquisition  of Enhanced in 1995;
breached certain terms of their respective  employment  contracts with Enhanced;
and converted  certain  corporate  assets of Enhanced,  breached their fiduciary
duties to Enhanced,  and  misappropriated  certain  corporate  opportunities for
their own  benefit.  The  Company and  Enhanced  are  seeking  compensatory  and
punitive  damages  against  Messrs.  Mittel and Taslimi.  On September 24, 1996,
Messrs.  Mittel and Taslimi filed a lawsuit in the United States  District Court
for the  Northern  District  of Georgia,  Atlanta  Division  (No.  196-CV-2463),
against the Company and Enhanced.  The lawsuit  alleges that  Enhanced  breached
Messrs.  Mittel's and Taslimi's respective  employment agreements by terminating
their employment.

A hearing to determine  appropriate venue for these cases was held in the United
States  District  Court for the District of Arizona in April 1997. The Court has
not  yet  reached  a  decision  on  this  matter.   In  May  1997,  the  parties
unsuccessfully  attempted to settle these matters through mediation. The Company
intends to proceed with its lawsuit  against  Messrs.  Mittel and Taslimi and to
vigorously defend the lawsuit filed by them against the Company and Enhanced.

- -22-
<PAGE>
                  2.1 Revolving Credit Facility.

                  (a)  Credit.  Upon and  subject  to the terms  and  conditions
hereof,  Lender  agrees  from time to time to make  available  by deposit to the
Disbursement Account on any Business Day until the Commitment  Termination Date,
upon the request of Borrower  therefor,  advances  (each,  a  "Revolving  Credit
Advance") in an aggregate amount  outstanding  that, when added to the aggregate
balance of Letter of Credit Obligations then outstanding, shall not at any given
time exceed the lesser of (the  "Revolving  Credit Advance  Availability"):  (i)
$12,000,000,  as such amount may be terminated  pursuant to the terms of Section
2.5 or 8.2 (the "Commitment"), and (ii) the Borrowing Base.

                  (b)  Method of  Borrowing.  Until the  Commitment  Termination
Date,  Borrower  may from time to time  borrow,  repay and  reborrow  under this
Section  2.1(b).  Each  Revolving  Credit  Advance  shall be made on  notice  by
Borrower  to  the  officer  of  Lender   identified  on  Schedule   2.1(b)  (the
"Responsible  Lending  Officer") given at the office of the Lender  specified on
Schedule 2.1(b) (the "Lending  Office") no later than 11:00 a.m. on the Business
Day of the proposed  Revolving  Credit  Advance.  Each such notice (a "Notice of
Borrowing/Collection  Report") shall be  substantially  in the form of Exhibit A
hereto,  and shall specify therein the requested date (which shall be a Business
Day) of the proposed  Revolving  Credit  Advance,  the amount of such  Revolving
Credit  Advance,  and such other  information  as may be  required by Lender and
shall be given in writing (by telecopy, telex or cable) or by courier, telephone
confirmed immediately in writing.

                  (c)  Mandatory  Repayment.  The entire  unpaid  balance of the
Revolving Credit Loan, together with all other Obligations, shall be immediately
due and  payable  on the  Commitment  Termination  Date.  In the event  that the
outstanding  principal  balance of the Revolving Credit Loan shall, at any time,
exceed  the  applicable  limit  set  forth in  Section  2.1(a),  Borrower  shall
immediately repay the Revolving Credit Loan in the amount of such excess. If the
unpaid principal  balance of the Revolving Credit Loan should at any time exceed
the  above-referenced  limit, the excess balance shall  nevertheless  constitute
Obligations  that are  secured  by the  Collateral  and  entitled  to all of the
benefits thereof and of the Loan Documents and shall be evidenced by the Note.

                  (d) Evidence of Obligation. The Revolving Credit Loan shall be
evidenced  by a note dated the  Closing  Date and  substantially  in the form of
Exhibit C (the "Note").  The Note shall  represent the obligation of Borrower to
pay the amount of the Revolving  Credit  Commitment  or, if less,  the aggregate
unpaid  principal  amount of all Revolving Credit Advances made by Lender to the
Borrower,  with  interest  thereon as  prescribed  in Section  2.2. The date and
amount of each  Revolving  Credit  Advance and each  payment of  principal  with
respect thereto shall be recorded on the books and records of Lender. Such books
and  records  shall  constitute  prima  facie  evidence  of the  accuracy of the
information therein recorded.

                  (e) Use of Proceeds.  Borrower  shall  utilize the proceeds of
the Revolving  Credit  Advances to provide  working capital for Borrower and the
other  Credit  Parties.  Borrower may request that Lender incur Letter of Credit
Obligations to support any
- -23-
<PAGE>
transaction for which Borrower could obtain a Revolving Credit Loan hereunder.

                  (f)  Single   Revolving  Credit  Loan.  All  Revolving  Credit
Advances  shall  constitute  a  single  Revolving  Credit  Loan  hereunder.  The
Revolving Credit Loan, any Letter of Credit Obligations,  and all Obligations of
Borrower  arising under this Agreement and under the other Loan Documents  shall
constitute  one general  obligation of Borrower to Lender  secured by all of the
Collateral.

                  (g) Letters of Credit.  Subject to the terms and conditions of
Schedule 2.1(g) which is hereby incorporated herein by reference, Borrower shall
have the  right to  request,  and  Lender  agrees  to  incur,  Letter  of Credit
Obligations for Borrower in accordance with Schedule 2.1(g).

                  2.2 Interest on Revolving Credit Loan.

                  (a) Rates.  The  Revolving  Credit Loan shall bear interest on
the  outstanding  principal  amount  thereof from and  including the date of the
making thereof until repaid in full,  whether before or after default  judgment,
or the  institution of  proceedings  under any  bankruptcy,  insolvency or other
similar law, as provided in this Section  2.2(a).  In the absence of an Event of
Default,  each  Revolving  Credit Loan shall bear  interest at the Base Rate. So
long as an Event of Default shall have occurred and be continuing, the Revolving
Credit Loan and, to the extent  permitted by Applicable  Law, all due and unpaid
Obligations  other than the  Revolving  Credit Loan,  shall bear interest at the
Default Rate.

                  (b) Payment. Interest shall be payable in arrears on the first
Business Day of each month with respect to interest accrued through the last day
of the preceding month and on the Commitment  Termination Date.  Interest at the
Default Rate shall be payable on demand.

                  (c) Maximum Permissible Rate.  Notwithstanding anything to the
contrary set forth in this Section 2.2, if, at any time until payment in full of
all of the Obligations, the amount deemed interest payable hereunder exceeds the
Maximum  Permissible  Rate,  then in  such  event  and so  long  as the  Maximum
Permissible Rate would be so exceeded,  the rate of interest  payable  hereunder
shall be equal to the Maximum Permissible Rate;  provided,  however,  that if at
any time  thereafter  the rate of interest  payable  hereunder  is less than the
Maximum  Permissible Rate,  Borrower shall continue to pay interest hereunder at
the Maximum  Permissible Rate until such time as the total interest  received by
Lender from the making of Revolving  Credit  Advances  hereunder is equal to the
total  interest  which Lender would have  received had the interest rate payable
hereunder  been (but for the  operation of this  paragraph)  the  interest  rate
payable  since  the  Closing  Date as  otherwise  provided  in  this  Agreement.
Thereafter,  the interest rate payable  hereunder  shall be the rate of interest
provided  in  Section  2.2(a) of this  Agreement,  unless  and until the rate of
interest  again  exceeds  the  Maximum  Permissible  Rate,  in which  event this
paragraph  shall again apply.  In no event shall the total interest  received by
Lender  pursuant  to the terms  hereof  exceed the  amount  which  Lender  could
lawfully have received had the interest due hereunder been
- -24-
<PAGE>
calculated  for the full term hereof at the  Maximum  Permissible  Rate.  In the
event the Maximum  Permissible  Rate is calculated  pursuant to this  paragraph,
such  interest  shall  be  calculated  at a  daily  rate  equal  to the  Maximum
Permissible  Rate  divided  by the  number  of days in the  year in  which  such
calculation  is  made.  In the  event  that a court of  competent  jurisdiction,
notwithstanding  the  provisions  of this  Section  2.2(c),  shall  make a final
determination  that Lender has received  interest  hereunder or under any of the
Revolving  Credit  Loan  Documents  in excess of the Maximum  Permissible  Rate,
Lender shall,  to the extent  permitted by Applicable  Law,  promptly apply such
excess  first  to any  interest  due  and not yet  paid  hereunder,  then to the
outstanding  principal  of the  Obligations,  then to Fees and any other  unpaid
Obligations and thereafter  shall refund any excess to Borrower or as a court of
competent jurisdiction may otherwise order.

                  2.3 Fees.

                  (a) Closing Fee. As additional compensation for Lender's costs
and risks in making this Revolving Credit Facility  available to Borrower during
its  initial  term,  Borrower  has paid to  Lender,  a  non-refundable  fee (the
"Closing  Fee") in an amount equal to $180,000,  less the Commitment Fee and any
remaining portion of the $100,000 initial underwriting deposit made to Lender by
Borrower  on  September  13,  1993 after  deducting  therefrom  (i) all cost and
expenses incurred by Lender and its Affiliates  (including,  but not limited to,
legal and professional  fees and costs of  indemnification)  and (ii) Commitment
Fee. The Closing Fee was deemed fully earned upon the  execution of the Original
Agreement.

                  (b) Non-use Fee. As additional compensation for Lender's costs
and risks in making the Commitment available to Borrower, Borrower agrees to pay
to Lender, in arrears for the preceding month, on the first Business Day of each
month prior to the Commitment Termination Date and on the Commitment Termination
Date, a fee for Borrower's  non-use of the Commitment  (the "Non-use Fee") in an
amount  equal to one  quarter of one  percent  (0.25%)  per annum on the average
daily Revolving Credit Commitment Availability.

                  (c) Letter of Credit Fees.  In  connection  with the Letter of
Credit  Obligations,  Borrower agrees to pay to Lender the Letter of Credit Fees
set forth on Schedule 2.1(g).

                  2.4  Calculation  of Interest and Fees.  All  computations  of
interest  and  periodic  fees  shall be made by Lender on the basis of a 360-day
year for the  actual  number of days  occurring  in the  period  for which  such
interest or fee is payable. If the date for any payment of principal is extended
(whether by operation of this  Agreement,  any  provision of law or  otherwise),
fees payable  pursuant to this  Agreement as well as interest,  shall be payable
for such extended time. Each  determination by Lender of an interest rate or fee
hereunder shall be presumed correct,  subject to the Borrower's ability to rebut
such presumption by a preponderance of evidence to the contrary.

                  2.5 Early  Termination.  Borrower  shall have the right at any
time, on 90
- -25-
<PAGE>
days' prior written notice to Lender,  to voluntarily  terminate the Commitment,
prepay the entire Revolving Credit Loan and all accrued and unpaid  Obligations,
cause  all  outstanding  Letter  of  Credit  Obligations  to be  cancelled,  and
terminate this Agreement.  Upon such  prepayment,  cancellation and termination,
Borrower's  right to receive  Revolving  Credit  Advances and to cause Lender to
incur  Letter  of  Credit  Obligations  shall  simultaneously   terminate.   Any
termination of the Commitment for any reason other than (i) Lender's  assessment
of a material change  pursuant to Section 2.10 or (ii) Lender's  acceleration of
the  Obligations  due to an Event of Default  pursuant  to clause (i) of Section
8.1(K),  shall require  prepayment of the outstanding  Revolving Credit Loan and
all accrued and unpaid Obligations and cancellation of all outstanding Letter of
Credit Obligations, and shall also require payment to Lender of a prepayment fee
(the  "Prepayment  Fee") as  follows:  one  percent  (1%) of the  amount  of the
Commitment if the  Commitment is terminated  prior to April 11, 1998. No partial
termination of the Revolving  Credit Facility by the Borrower shall be permitted
without the consent of Lender.

                  2.6 Manner of Payment; Time.

                  (a) Manner of Payment.  Borrower shall make each payment under
this  Agreement not later than 11:00 a.m. on the day when due in lawful money of
the United  States of  America in  immediately  available  funds to the  Payment
Account  without any deduction  whatsoever,  including,  but not limited to, any
deduction for any set-off, recoupment,  counterclaim or Tax. Amounts received to
the Payment  Account  shall be deemed  received  (i) on the second  Business Day
following the irrevocable  deposit therein of collected  funds, for the purposes
of  calculating  accrual of  interest,  and (ii) on the date of the  irrevocable
deposit   therein  of  collected   funds,   for  the  purposes  of   calculating
availability.  Amounts  received to the Payment Account shall be applied against
the outstanding Obligations pursuant to Section 2.7.

                  (b) Time. All references to time contained in this  Agreement,
unless  otherwise  specified,  shall be to local time in effect in Los  Angeles,
California.

                  2.7   Application   and   Allocation  of  Payments.   Borrower
irrevocably  waives the right to direct the  application of any and all payments
at any time or times  hereafter  received  from or on  behalf of  Borrower,  and
Borrower  irrevocably  agrees that Lender  shall have the  continuing  exclusive
right  to apply  any and all  such  payments  against  the then due and  payable
Obligations  of  Borrower  as Lender  may deem  advisable.  In the  absence of a
specific determination by Lender with respect thereto, the same shall be applied
in the following  order:  (i) then due and payable Fees and expenses;  (ii) then
due and payable interest payments;  (iii) Obligations other than Fees,  expenses
and interest and  principal  payments;  and (iv) then due and payable  principal
payments  on the  Revolving  Credit  Loan and the Letter of Credit  Obligations.
Lender  is  authorized  to,  and at its  option  may,  make or  cause to be made
Revolving Credit Advances on behalf of Borrower under this Agreement for payment
of all Fees, expenses,  Charges, costs, interest,  reimbursement  obligations or
other  Obligations  owing by Borrower  under this  Agreement  or any of the Loan
Documents if and to the extent  Borrower  fails to promptly pay any such amounts
as and when due.
- -26-
<PAGE>
                  2.8  Accounting.  Lender will provide a monthly  accounting of
transactions  under the Revolving  Credit  Facility to Borrower.  Each and every
such accounting  shall be deemed final,  binding and conclusive upon Borrower in
all respects as to all matters  reflected  therein,  unless Borrower,  within 30
days after the date any such  accounting  is rendered,  shall  notify  Lender in
writing  of any  objection  which  Borrower  may  have to any  such  accounting,
describing the basis for such objection with  specificity.  In that event,  only
those items expressly  objected to in such notice shall be deemed to be disputed
by Borrower. Lender's determination, based upon the facts available, of any item
objected to by Borrower in such notice shall be presumed correct, subject to the
Borrower's  ability to rebut such  presumption by a preponderance of evidence to
the contrary.

                  2.9 Taxes.

                  (a) Any and all payments by or on behalf of Borrower hereunder
or under any Note or any other Loan Document  shall be made, in accordance  with
this  Section  2.9,  free and  clear of and  without  deduction  for any and all
present or future  Taxes.  If Borrower or any other  Person shall be required by
law to deduct any Taxes from or in respect of any sum payable hereunder or under
the Note or any other Loan  Document  to Lender,  (i) the sum  payable  shall be
increased  as may be  necessary  so that after  making all  required  deductions
(including  deductions  applicable to additional sums payable under this Section
2.9) Lender  receives an amount  equal to the sum it would have  received had no
such  deductions  been made by Borrower or such other  Person,  (ii) Borrower or
such other Person shall make such  deductions,  and (iii) Borrower or such other
Person  shall  pay the full  amount  deducted  to the  relevant  taxing or other
authority in accordance with Applicable Law.

                  (b) Borrower shall indemnify and pay, within 10 days of demand
therefor, Lender for the full amount of Taxes (including without limitation, any
Taxes  imposed by any  jurisdiction  on amounts  payable under this Section 2.9)
paid by Lender and any liability  (including  penalties,  interest and expenses)
arising  therefrom  or with  respect  thereto,  whether  or not such  Taxes were
correctly  or  legally  asserted;  provided,  however,  that  Borrower  shall be
entitled to a credit  against the  Obligations to the extent that any such Taxes
paid by Borrower  pursuant to this Section 2.9 are subsequently  refunded to the
Lender or to the extent  that the Lender  receives  a credit  against  the Taxes
imposed on it by its  jurisdiction of  incorporation by virtue of the Taxes paid
or  reimbursed  by Borrower  under this Section 2.9 having been paid by it or on
its behalf.

                  (c)  Within  30 days  after the date of any  payment  of Taxes
pursuant to this Section 2.9, Borrower shall furnish or cause to be furnished to
Lender,  at its address referred to in Section 9.10, the original or a certified
copy of a receipt evidencing payment thereof.

                  2.10  Increased  Commitment  or Funding  Costs.  If the Lender
reasonably  determines that either (a) the  introduction of or any change in any
Laws or in the  interpretation  or administration of any Law by any Governmental
Authority charged with the  interpretation  or administration  thereof after the
date of this Agreement relating to the regulation of banks or commercial lenders
or (b) compliance with any guideline or request
- -27-
<PAGE>
issued  or made  after  the date  hereof  from any such  Governmental  Authority
relating to the regulation of banks or commercial lenders (whether or not having
the force of law) has or would have the effect of reducing the rate of return on
the capital of Lender or any corporation  controlling Lender as a consequence of
or with reference to Lender's funding,  incurring or maintaining the Commitment,
any Revolving  Credit Advance,  any Letter of Credit  Obligation,  the Revolving
Credit Loan or any other extension of credit or transaction  hereunder below the
rate that  Lender or such other  corporation  could have  achieved  but for such
introduction,  change or compliance  (taking into account the policies of Lender
or corporation  with regard to capital),  then Borrower shall from time to time,
upon demand by Lender, pay to Lender additional amounts sufficient to compensate
Lender or other  corporation for such  reduction.  Any notice under this Section
2.10 shall be given to Borrower as promptly as practicable  after Lender obtains
knowledge of such change,  guideline  or request and shall be  accompanied  by a
certificate  from  Lender  setting  forth in  reasonable  detail  the nature and
calculation of the relevant amounts.

                  2.11 Failure to Charge Not Subsequent  Waiver.  Any failure by
Lender to require  payment of any  interest  (including  interest at the Default
Rate),  fee,  cost or  other  amount  payable  under  any Loan  Document,  or to
calculate any amount payable by a particular method, on any occasion shall in no
way limit to be deemed a waiver of Lender's right to require full payment of any
such interest, fee, cost or other amount payable by another method, on any other
or subsequent occasion.

                  2.12  Survivability.   All  of  Borrower's  obligations  under
Sections  2.9 and 2.10 shall  survive  the  payment  in full of all  obligations
hereunder.

the Restatement Date and as of the date of each such funding:

                  (a)  Each  of the  representations  and  warranties  contained
herein or in any of the other Loan Documents is true and correct,  except to the
extent that any such  representation or warranty expressly relates to an earlier

contemplated  by this  Agreement,  both before and after  giving  effect to such
Revolving Credit Advance or Letter of Credit Obligation;

                  (b) No Default has occurred and is continuing either before or
after  giving  effect to the  requested  Revolving  Credit  Advance or Letter of
Credit Obligation; and

such Letter
- -28-
<PAGE>
of Credit Obligation, (i) the aggregate principal amount of the Revolving Credit
Loan plus the aggregate  principal  amount of the  outstanding  Letter of Credit
Obligations  does  not  exceed  the  lesser  of (x) the  Commitment  and (y) the
Borrowing Base, without requiring that a payment be made to Lender, and (ii) the
aggregate  outstanding  amount at such time of all Letter of Credit  Obligations
incurred by Lender does not exceed $1,000,000.

constitute,  as of the date of such request or acceptance,  (i) a representation
and  warranty  by Borrower  that the  conditions  in this  Section 3.1 have been
satisfied and (ii) a confirmation by Borrower of the granting and continuance of
Lender's Liens pursuant to the Collateral Documents,  unless in each case (i) or
(ii), a notice to the contrary specifically  captioned "Disclosure Statement" is

preceding  the date of the  Revolving  Credit  Advance.  To the extent  that the
Lender  agrees to make any  Extension  of Credit  after  receipt of a Disclosure
Statement in accordance with the preceding  sentence,  the  representations  and
warranties and  confirmation  pursuant to the preceding  sentence will be deemed
made as modified by the contents of such  statement  and repeated at the time of
the making of such  Extension  of Credit as so modified.  Any such  modification
shall be effective only for the occasion on which the Lender elects to make such
Extension of Credit, and unless expressly agreed by the Lender in writing to the
contrary  as  provided  in  Section  9.1,  shall  not  be  deemed  a  waiver  or
modification of any condition to any future Extension of Credit.

                                   ARTICLE 4.

                         REPRESENTATIONS AND WARRANTIES

                  To induce the Lender to make this  Revolving  Credit  Facility

Agreement and shall survive the execution and delivery of this Agreement:

Party (i) is a corporation duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation and is duly qualified to
do  business  and is in good  standing  in each  other  jurisdiction  where  its
ownership  or lease of  property or the conduct of its  business  requires  such
qualification,  except  where the  failure to so qualify or be in good  standing
could not reasonably be expected to have a Materially  Adverse Effect;  (ii) has
the requisite  corporate power and authority and the legal right to own, pledge,
mortgage or otherwise encumber and operate its properties, to lease the property
it operates  under  lease,  and to conduct its business as now,  heretofore  and

could not reasonably be expected to have a Materially Adverse Effect;  (iii) has
all  licenses,  permits,  consents  or  approvals  from or by,  and has made all
filings with, and has given all notices to, all Governmental  Authorities having
jurisdiction, to
- -29-
<PAGE>
the extent required for such ownership, lease operation and conduct, except such
of the foregoing,  that the failure to have, to have made or to have given which
could not reasonably be expected to have a Materially Adverse Effect; (iv) is in
compliance with its certificate or articles of  incorporation  and by-laws;  and
(v) is in compliance  with all provisions of Applicable Law where the failure to
comply could reasonably be expected to have a Materially Adverse Effect.

                  4.2 Executive Offices; Corporate or Other Names.

                  (a) The current locations of Borrower's chief executive office
and principal place of business are as set forth in response to question 6.a. of
the Credit Party Questionnaire  completed by the Borrower.  During the preceding
five (5) years,  neither the  Borrower nor Vodavi have been known as or used any
corporate, fictitious or trade names except as disclosed in response to question
2 of the Credit Party Questionnaire  completed by the Borrower. The Borrower has
no  professional  office  locations  except as  disclosed  in the  Credit  Party
Questionnaire completed by the Borrower.

                  (b) The current  locations of the chief  executive  office and
principal  place of business of each of ARS and ESI are as set forth in response
to question  6.a. of the Credit  Party  Questionnaire  completed  by such Credit
Party. During the preceding five (5) years,  neither ARS nor ESI have been known
as or used any  corporate,  fictitious  or trade names  except as  disclosed  in
response  to  question 2 of the Credit  Party  Questionnaire  completed  by such
Credit Party.  Neither ARS nor ESI have any professional office locations except
as disclosed on the Credit Party Questionnaire completed by such Credit Party.

                  4.3 Corporate Power;  Authorization;  Enforceable Obligations.
The  execution,  delivery  and  performance  by each  Credit  Party  of the Loan
Documents  executed by such Credit Party and of all instruments and documents to
be delivered by such Credit Party  hereunder and  thereunder and the creation of
all Liens  provided for herein and therein:  (i) are within such Credit  Party's
corporate power;  (ii) have been duly authorized by all necessary  corporate and
shareholder  action;  (iii) are not in  contravention  of any  provision of such
Credit Party's certificate or articles of incorporation or by-laws;  (iv) do not
violate  any  law or  regulation,  or any  order  or  decree  of  any  court  or
governmental  instrumentality  applicable  to  such  Credit  Party;  (v)  do not
conflict with or result in the breach or  termination  of,  constitute a default
under or  accelerate  any  performance  required  by,  any  material  indenture,
mortgage,  deed of trust,  lease,  note,  loan  agreement or other  agreement or
instrument  to which such Credit  Party is a party or by which such Credit Party
or any of  its  property  is  bound;  (vi)  do not  result  in the  creation  or
imposition  of any Lien upon any of the property of such Credit Party other than
those in favor of Lender created  pursuant to the Loan  Documents;  and (vii) do

Person,  except those delivered to Lender pursuant to Section 9.18(a) and except
those not yet required to have been  obtained,  all of which will have been duly
obtained,  made or  complied  with.  Each of the Loan  Documents  has been  duly
executed and  delivered  by each Credit Party which is a party  thereto and each
constitutes  the legal,  valid and  binding  obligation  of such  Credit  Party,
enforceable  against it in  accordance  with its terms except to the extent that
such
- -30-
<PAGE>
enforceability may be effected by bankruptcy,  insolvency,  reorganization,
moratorium or other similar laws  affecting the rights and remedies of creditors
generally, and general principles of equity.

                  4.4 Financial  Statements and  Projections.  Schedule 4.4 sets
forth  the  latest  financial  statements  and  Projections  that  Borrower  has
delivered to Lender prior to the Restatement Date. All of the balance sheets and
statements  of income,  retained  earnings  and cash flows of the Parent and the
Credit  Parties  listed on  Schedule  4.4 have  been,  except as noted  therein,
prepared in conformity  with GAAP and present  fairly the financial  position of
the  Parent  or such  Credit  Party,  as the case may be, in each case as of the
dates thereof, and the results of operations and cash flows for the periods then
ended (as to the  unaudited  interim  financial  statements,  subject  to normal
year-end  audit  adjustments  and the  absence of  footnotes).  The  Projections
disclose  all  material  assumptions  made with  respect  to  general  economic,
financial and market conditions in formulating such Projections.  No facts exist
as of the date of any making of this  representation  that  would  result in any
material  change in any of such  Projections.  The  Projections  are based  upon
reasonable  estimates and  assumptions,  all of which are reasonable in light of
conditions  existing at the Restatement Date, have been prepared on the basis of
the assumptions stated therein,  and reflect the reasonable estimate of Borrower
of the results of operations and other information projected therein.

                  4.5 Material  Adverse  Change.  Except as disclosed in audited
consolidated  financial statements of the Parent Group for the fiscal year ended
December 31,  1996,  that were  delivered to the Lender,  Borrower and the other
Credit Parties have no obligations,  contingent liabilities,  or liabilities for
Charges,  long-term  leases or unusual  forward or  long-term  commitments  that
could,  alone or in the aggregate,  have or result in a Material Adverse Effect.
Since  December 31, 1996,  (i) there has been no material  adverse change in the
business,  assets,  operations,  prospects or  financial  or other  condition of
Borrower or the Parent  Group,  taken as a whole,  and (ii) no Credit  Party has
paid,  made or  declared  any  dividend,  advance or other  distribution  to any
stockholder  of  such  Credit  Party,  except  as  permitted  pursuant  to  this
Agreement. No shares of stock of any Credit Party have been, or are now required
to be, redeemed,  retired, purchased or otherwise acquired for value by Borrower
and there exists no present agreement, understanding or requirements (contingent
or otherwise)  to redeem,  retire,  purchase or otherwise  acquire for value any
such shares in the future except as disclosed on Schedule 4.5.

                  4.6      Ownership of Property; Liens.
- -31-
<PAGE>
                  (a) The real estate listed on Schedule 4.6  constitutes all of
the real  property  owned,  leased,  or used in its  business by Borrower or any
other Credit Party. Except as disclosed on Schedule 4.6, each Credit Party owns:
(i) good and marketable fee simple title to all of the real estate owned or used
by it other  than such as its holds as  lessee,  and (ii)  valid and  marketable
leasehold  interests in all of its Leases (both as lessor and lessee,  sublessee
or assignee). Except as disclosed on Schedule 4.6, each Credit Party holds title
to, or valid  leasehold  interests in, all of its other  properties  and assets.
None of the  properties  or assets of any Credit  Party is subject to any Liens,
except (x) Permitted  Encumbrances and (y) the Liens in favor of Lender pursuant
to  the  Collateral  Documents.  Each  Credit  Party  has  received  all  deeds,
assignments,  waivers,  consents,  non-disturbance  and  recognition  or similar
agreements, bills of sale and other documents, and duly effected all recordings,
filings and other actions necessary to establish, protect and perfect its right,
title and  interest in and to all such real estate and other assets or property.
Except as  described  on Schedule  4.6,  (i) none of the Credit  Parties nor any
other party to any such Lease  described  on  Schedule  4.6 is in default of its
obligations  thereunder or has delivered or received any notice of default under
any such Lease, and no event has occurred which, with the giving of notice,  the
passage of time or both, would  constitute a default under any such Lease,  (ii)
none of the Credit Parties owns or holds,  or is obligated  under or a party to,
any option,  right of first refusal or any other  contractual right to purchase,
acquire,  sell,  assign or dispose of any real property  owned or leased by such
Person,  and (iii) no portion of any real property owned or leased by any Credit
Party has  suffered  any  material  damage by fire or other  casualty  loss or a
Release which has not heretofore  been  completely  repaired and restored to its
original  condition  or is being  remedied.  All  permits  required to have been
issued or  appropriate to enable the real property owned or leased by any Credit
Party to be lawfully  occupied  and used for all of the  purposes for which they
are currently  occupied and used,  have been lawfully  issued and are, as of the
date hereof, in full force and effect.

                  4.7 Restrictions;  No Default. No contract,  lease, agreement,
judgment,  decree or other  instrument  or order to which any Credit  Party is a
party or by which it or any of its properties or assets is bound or affected and
no provision  of existing  Applicable  Law has or results in a Material  Adverse
Effect,  or insofar as any Credit  Party can  reasonably  foresee  could have or
result in a Material  Adverse Effect.  None of the Credit Parties is in default,
and to each Credit Party's knowledge no third party is in default, under or with
respect to any material contract,  agreement, lease or other instrument to which
any Credit Party is a party. No Default has occurred and is continuing.

                  4.8  Labor  Matters.  There  are no  strikes  or  other  labor
disputes  against any Credit  Party that are  pending or, to any Credit  Party's
knowledge, threatened which could have or result in a Material Adverse Effect or
could  cause or result  in the  incurrence  by any  Credit  Party of a  material
liability,  contingent  or  liquidated.  Hours  worked  by and  payment  made to
employees  of each  Credit  Party have not been in  violation  of the Fair Labor
Standards Act or any other  applicable law dealing with such matters which could
have or  result in a  Material  Adverse  Effect or could  cause or result in the
incurrence  by  any  Credit  Party  of  a  material  liability,   contingent  or
liquidated. All payments due from any Credit Party
- -32-
<PAGE>
on account of employee  health and welfare  insurance which could have or result
in a Material  Adverse  Effect or could cause or result in the incurrence by any
Credit Party of a material liability, contingent or liquidated, if not paid have
been paid or accrued as a liability on the books of such Credit  Party.  None of
the Credit Parties has any obligation under any collective  bargaining agreement
or any employment  agreement,  except as disclosed on Schedule 4.16 or permitted
pursuant to Section 7.4.  There is no organizing  activity  involving any Credit
Party pending or threatened by any labor union or group of employees.  Except as
set forth on Schedule 4.14, there are no  representation  proceedings  involving
employees  of any Credit Party  pending or  threatened  with the National  Labor
Relations Board,  and no labor  organization or group of employees of any Credit
Party  have  made a  pending  demand  for  recognition.  Except  as set forth on
Schedule  4.14,  there are no  complaints  or charges  against any Credit  Party
pending or  threatened  to be filed with any  federal,  state,  local or foreign
court, governmental agency or arbitrator based on, arising out of, in connection
with, or otherwise  relating to the  employment or  termination of employment by
any Credit Party of any  individual,  except such  complaints  and charges that,
singularly or in the aggregate,  would not require notice to the Lender pursuant
to Section 6.4.

                  4.9 Ventures,  Subsidiaries and Affiliates,  and Indebtedness.
Except as set forth on  Schedule  4.9,  neither the Parent nor any of the Credit
Parties has any  Subsidiaries,  is engaged in any joint  venture or  partnership
with any other Person,  or is an Affiliate of any other Person.  All outstanding
Stock and  Indebtedness  in excess of $25,000  of each of the Credit  Parties is
described on Schedule 4.9.

                  4.10 Government  Regulation.  None of the Credit Parties is an
"investment  company" or an "affiliated  person" of, or "promoter" or "principal
underwriter"  for,  an  "investment  company,"  as such terms are defined in the
Investment Company Act of 1940 as amended. None of the Credit Parties is subject
to regulation  under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the  Interstate  Commerce Act or any other  federal or state  statute
that restricts or limits its ability to incur Indebtedness, pledge its assets or
to perform its  obligations  hereunder or under any other Loan  Document and the
making of the  Revolving  Credit  Advances  by Lender,  the  application  of the
proceeds  and  repayment  thereof by Borrower or any other  Credit Party and the
consummation  of the  transactions  contemplated by this Agreement and the other
Loan  Documents  will not violate any provision of any such statute or any rule,
regulation or order issued by the  Securities  and Exchange  Commission  (except
that no representation is made concerning  whether any syndication or assignment
by Lender might or would violate any Federal  securities  laws,  regulations  or
orders).

                  4.11 Margin  Regulations.  None of the Credit Parties owns any
"margin  security",  as that term is defined in Regulations G and U of the Board
of Governors of the Federal Reserve System (the "Federal  Reserve  Board"),  and
none of the proceeds of the Revolving Credit Advances will be used,  directly or
indirectly,  for the purpose of purchasing or carrying any margin security,  for
the  purpose of  reducing  or retiring  any  indebtedness  which was  originally
incurred to purchase or carry any margin security or for any other purpose which
might cause any of the loans or other extensions of credit under this
- -33-
<PAGE>
Agreement to be considered a "purpose  credit"  within the meaning of Regulation
G, T, U or X of the Federal Reserve Board.  None of the Credit Parties will take
or permit  to be taken any  action  which  might  cause  this  Agreement  or any
document or instrument  delivered  pursuant  hereto to violate any regulation of
the Federal Reserve Board.

                  4.12 Taxes. All federal, state, local and foreign tax returns,
reports  and  statements  required to be filed by any Credit  Party  (except for
sales and use tax returns involving, in the aggregate, immaterial amounts), have
been filed with the appropriate Governmental Authority and all Charges and other
impositions  shown thereon to be due and payable that are or could reasonably be
expected to become a liability or charge  against any Credit Party or its assets
have been paid prior to the date on which any fine,  penalty,  interest  or late
charge may be added thereto for nonpayment  thereof,  or any such fine, penalty,
interest,  late charge or loss has been paid,  except for  non-compliances  that
could not  reasonably be expected to have a Material  Adverse Effect or to cause
or  result  in the  incurrence  by any  Credit  Party of a  material  liability,
contingent  or  liquidated.  Each  of the  Credit  Parties  has  paid  prior  to
delinquency  all Charges which such Credit Party  reasonably  expects it will be
required  to be  paid  by  them,  except  for  non-compliances  that  could  not
reasonably be expected to have a Material  Adverse  Effect or to cause or result
in the  incurrence  by any Credit Party of a material  liability,  contingent or
liquidated. Proper and accurate amounts have been withheld by each of the Credit
Parties  from its  respective  employees  for all  periods in full and  complete
compliance with the tax, social security and unemployment withholding provisions
of applicable  federal,  state, local and foreign law and such withholdings have
been  timely  paid  to  the  respective  Governmental  Authorities,  except  for
non-compliances that could not reasonably be expected to have a Material Adverse
Effect or to cause or result in the incurrence by any Credit Party of a material
liability,  contingent  or  liquidated.  Schedule  4.12 sets forth those taxable
years for which any Credit  Party's tax returns are  currently  being audited by
the IRS or any other  applicable  Governmental  Authority and any assessments or
threatened  assessments  in  connection  with such audit or which are  otherwise
currently outstanding.  Except as described on Schedule 4.12, none of the Credit
Parties has executed or filed with the IRS or any other  Governmental  Authority
any agreement or other  document  extending,  or having the effect of extending,
the period for  assessment  or  collection  of any  Charges.  None of the Credit
Parties has any obligation under any written tax sharing agreement except as set
forth on Schedule 4.12.

                  4.13 ERISA.

                  (a) Schedule 4.13 lists all Plans maintained or contributed to
by any Credit Party and all Qualified Plans  maintained or contributed to by any
other  ERISA   Affiliate,   and  separately   identifies  the  Title  IV  Plans,
Multiemployer  Plans,  any multiple  employer  plans  subject to Section 4064 of
ERISA,  unfunded  Pension Plans,  Welfare Plans and Retiree Welfare Plans.  Each
Qualified Plan has been  determined by the IRS to qualify under IRC Section 401,
and the trusts  created  thereunder  have been  determined to be exempt from tax
under the  provisions  of IRC Section  501,  and to the best  knowledge  of each
Credit  Party   nothing  has  occurred   that  would  cause  the  loss  of  such
qualification  or  tax-exempt  status.  Each  Plan  is in  compliance  with  the
applicable  provisions  of ERISA and the IRC,  including  the  filing of reports
required under the IRC or ERISA which are true and correct as of the date filed,
and with  respect  to each Plan,  other  than a  Qualified  Plan,  all  required
contributions  and benefits have been paid in accordance  with the provisions of
each such Plan.  None of the Credit Parties or any other ERISA  Affiliate,  with
respect to any Qualified  Plan, has failed to make any  contribution  or pay any
amount due as  required  by IRC Section 412 or Section 302 of ERISA or the terms
of any such Plan. With respect to all Retiree  Welfare Plans,  the present value
of future anticipated  expenses pursuant to the latest actuarial  projections of
liabilities does not exceed $50,000,  and copies of such latest projections have
been provided to Lender;  with respect to Pension  Plans,  other than  Qualified
Plans, the present value of the liabilities for current participants  thereunder
using PBGC  interest  assumptions  does not exceed  $50,000.  None of the Credit
Parties has engaged in a prohibited  transaction,  as defined in Section 4975 of
the IRC or  Section  406 of ERISA,  in  connection  with any Plan,  which  would
subject any Credit Party (after  giving  effect to any  exemption) to a material
tax on prohibited transactions imposed by IRC Section 4975 or any other material
liability.

                  (b) Except as set forth on Schedule 4.13: (i) no Title IV Plan
has any Unfunded  Pension  Liability;  (ii) No ERISA Event or event described in
Section  4062(e) of ERISA with  respect to any Title IV Plan has  occurred or is
reasonably expected to occur; (iii) there are no pending, or to the knowledge of
any Credit Party,  threatened claims, actions or lawsuits (other than claims for
benefits in the normal course),  asserted or instituted  against (x) any Plan or
its assets,  (y) any fiduciary  with respect to any Plan or (z) any Credit Party
or any other ERISA  Affiliate with respect to any Plan;  (iv) none of the Credit
Parties or any other ERISA Affiliate has incurred or reasonably expects to incur
any Withdrawal  Liability (and no event has occurred  which,  with the giving of
notice  under  Section  4219 of ERISA,  would  result in such  liability)  under
Section  4201 of ERISA as a result of a complete  or partial  withdrawal  from a
Multiemployer Plan; (v) within the last five years none of the Credit Parties or
any other ERISA Affiliate has engaged in a transaction which resulted in a Title
IV Plan with Unfunded  Liabilities being transferred  outside of the "controlled
group" (within the meaning of Section  4001(a)(14) of ERISA) of any such entity;
(vi) no plan which is a Retiree Welfare Plan provides for continuing benefits or
coverage for any  participant  or any  beneficiary  of a participant  after such
participant's  termination  of  employment  (except  as may be  required  by IRC
Section 4980B and at the sole expense of the  participant or the  beneficiary of
the participant); the Credit Parties and other ERISA Affiliates have complied
- -35-
<PAGE>
with the notice and continuation  coverage requirements of IRC Section 4980B and
the regulations  thereunder except where the failure to comply could not have or
result in any Material Adverse Effect; and (vii) no liability under any Plan has
been funded,  nor has such  obligation  been  satisfied,  with the purchase of a
contract  from an  insurance  company  that is not rated AAA by the  Standard  &
Poor's Corporation and the equivalent by each other nationally recognized rating
agency.

                  4.14 No  Litigation.  Except as set forth on Schedule 4.14, no
action, claim or proceeding is now pending or, to the knowledge of an officer of
any Credit  Party,  threatened  against  any Credit  Party at law,  in equity or
otherwise, before any court, board, commission, agency or instrumentality of any
federal, state or local government,  or of any agency or subdivision thereof, or
before any arbitrator or panel of  arbitrators,  (i) that  challenges any Credit
Party's  right,  power  or  competence  to  enter  into  or  perform  any of its
obligations  under the Loan Documents,  or the validity or enforceability of the
Security  Interest or of any Loan Document or any action hereunder or thereunder
or (ii) that if determined adversely, could have or result in a Material Adverse
Effect or could  cause or  result in the  incurrence  by any  Credit  Party of a
material liability, contingent or liquidated, nor to the knowledge of an officer
of any Credit  Party does a state of facts  exist that is  reasonably  likely to
give rise to any such action, claim or proceeding.

                  4.15 Brokers.  Except as set forth on Schedule 4.15, no broker
or finder  acting on behalf of Borrower or any other Credit Party  brought about
the obtaining, making or closing of the loans made pursuant to this Agreement or
the transactions contemplated by the Loan Documents and neither Borrower nor any
other Credit Party has any  obligations to any Person in respect of any finder's
or brokerage fees in connection therewith.

                  4.16 Employment Matters.  Except as set forth on Schedule 4.16
or permitted  pursuant to Section 7.4,  there are no  employment,  consulting or
management  agreements  covering  management  of any  Credit  Party.  A true and
complete copy of each such agreement has been furnished to Lender by Borrower.

                  4.17   Patents,   Trademarks,    Copyrights,    Licenses   and
Accreditation. Except as otherwise set forth on Schedule 4.17, each Credit Party
owns or has undisputed possession of all licenses, patents, patent applications,
copyrights,  service marks,  trademarks,  trademark  applications,  trade names,
certificates of need and accreditation  and other rights,  the failure to own or
possess which could have a Material  Adverse  Effect or could cause or result in
the  incurrence  by any Credit  Party of a  material  liability,  contingent  or
liquidated,  each of which is listed,  together with Patent and Trademark Office
application or registration  numbers,  where applicable,  on Schedule 4.17. Each
Credit Party is in full compliance with the provisions of each of the foregoing,
except for  non-compliances  that could not  reasonably  be  expected  to have a
Material  Adverse  Effect or to cause or result in the incurrence by such Credit
Party of a material liability, contingent or liquidated. Schedule 4.17 lists all
trade  names or other  names  under  which any of the  Credit  Parties  conducts

- -36-

property  right  of  others,   except  where  such   infringement  or  claim  of
infringement  could not have or result in a Material Adverse Effect or could not
cause or result in the incurrence by such Credit Party of a material  liability,
contingent or liquidated.  There is no  infringement or claim of infringement by
others of any material  license,  patent,  copyright,  service mark,  trademark,
trade name,  trade  secret or other  intellectual  property  right of any Credit
Party.

                  4.18  Full  Disclosure.   No  information  contained  in  this
Agreement,  the other Loan  Documents,  the  Projections,  the Financials or any
written  statement  furnished  to the Lender by or on behalf of any Credit Party
pursuant to the terms of this Agreement or any other Loan Document, contains any
untrue  statement of a material fact or omits to state a material fact necessary
to make the  statements  contained  herein or therein not misleading in light of
the circumstances  under which they were made. The Security Interests granted to
Lender pursuant to the Collateral Documents will at all times be fully perfected
first priority Liens in and to the Collateral described therein, subject only to
such exceptions as are permitted under the applicable  Collateral  Document.  No
event has occurred  since  December 31, 1996 and is  continuing  that has had or
could have or result in a Material Adverse Effect.

                  4.19  Hazardous  Materials.  Except as set  forth on  Schedule
4.19, the Subject Property is free of contamination  from any Hazardous Material
that would  constitute  a  violation  of any  Environmental  Law.  In  addition,
Schedule 4.19  discloses  potential  material  environmental  liabilities of any
Credit Party of which an officer of such Credit Party has  knowledge (i) related
to noncompliance with the Environmental Laws or (ii) associated with the Subject
Property. None of the Credit Parties has caused or suffered to occur any Release
with respect to any Hazardous  Material that would constitute a violation of any
Environmental  Law at, under,  above or within any real property that it owns or
leases.  None of the  Credit  Parties  is  involved  in  operations  that  could
reasonably be expected to lead to the imposition of any liability or Lien on it,
its property,  or any premises that it occupies or any owner thereof,  under the
Environmental  Laws,  and none of the Credit Parties has permitted any tenant or
occupant of such premises to engage in any such activity.

insurance of any nature  maintained by the Credit Parties,  as well as a summary
of the terms of such insurance.  Such insurance  complies with the standards set
forth on Schedule  4.20 Part I, and all policies  listed on such schedule are in
full force and effect.

                  4.21 Deposit Accounts. Schedule 4.21 lists all banks and other
financial  institutions  at which any of the Credit Parties  maintains  deposits
and/or other  accounts,  and  identifies as such each  Collection  Account,  the
Disbursement  Account,  and such Schedule correctly identifies the name, address
and telephone number of each depository,  the name in which the account is held,
a description of the purpose of the account, and the complete account number.

                  4.22 Solvent Financial Condition. Each of the Borrower and the
Parent  Group,  taken  as a  whole,  is now,  and  after  giving  effect  to the
incurrence  of the  obligations  and  the  granting  of the  Security  Interests
contemplated hereunder and under the other Loan

legal  actions or  proceedings,  the validity or amount of any Charges or claims

                  6.5 Insurance.

                  (a) Each Credit  Party,  at its sole cost and  expense,  shall
maintain or cause to be  maintained  the  policies  of  insurance  described  on
Schedule 4.20 in form, with such  endorsements  and with insurers  recognized as
adequate by Lender.  Such  polices  shall be in such amounts as are set forth on
Schedule  4.20 or such lesser  amounts as the Lender shall  reasonably  agree in
writing.  Each  Credit  Party  shall  notify  Lender  promptly  of any  casualty
occurrence  causing a material  loss or decline in value of any real or personal
property and the  estimated  (or actual,  if  available)  amount of such loss or
decline. In the event any Credit Party at any time or times hereafter shall fail
to obtain or maintain  any of the  policies  of  insurance  required  above that
insure  the  Collateral  or to pay any  premium  in  whole  or in part  relating
thereto,  Lender,  without  waiving  or  releasing  any  Obligation  or  Default
hereunder,  may at any time or times  thereafter (but shall not be obligated to)
obtain and maintain such policies of insurance and pay such premium and take any
other action with respect  thereto  which  Lender deems  advisable.  All sums so
disbursed,  including reasonable  attorneys' fees, court costs and other charges
related thereto, shall be payable, on demand, by Borrower to Lender and shall be
additional  Obligations hereunder secured by the Collateral,  provided,  that if
and to the extent  Borrower fails to promptly pay any of such sums upon Lender's
demand  therefor,  Lender is authorized to, and at its option may, make or cause
to be made Revolving Credit Advances on behalf of Borrower for payment thereof.

                  (b) Lender  reserves the right at any time, upon review of any
Credit Party's risk profile, to require additional forms and limits of insurance
to, in Lender's reasonable opinion,  adequately protect Lender's interest.  Each
Credit Party shall,  if so requested by Lender,  deliver to Lender,  as often as
Lender may request,  a report of a reputable  insurance broker,  satisfactory to
Lender with respect to its insurance policies.

                  (c) Each Credit Party shall deliver to Lender  endorsements to
all of its general  liability  and other  liability  policies  naming  Lender an
additional insured.

those relating to licensing,  environmental,  consumer  credit,  ERISA and labor
matters.

                  6.7  Agreements.  Each Credit Party shall perform,  within all
required time periods (after giving effect to any applicable grace periods), all
of its  obligations  and enforce all of its rights under each agreement to which
such  Credit  Party is a party,  including,  without  limitation,  any lease and
customer  contracts  to which  such  Person is a party  where the  failure to so
perform  and enforce  could  reasonably  be expected to have a Material  Adverse
Effect  or to  cause  or  result  in the  incurrence  of a  material  liability,
contingent or liquidated.  None of the Credit Parties shall  terminate or modify
any  provision  of any  agreement  to which it is a party which  termination  or
modification  could  reasonably  be  expected  to have or result  in a  Material
Adverse Effect or to cause or result in the incurrence by such Credit Party of a
material liability, contingent or liquidated.

threatened  litigation  or  claims,  against  such  Credit  Party  or any  ERISA
Affiliate  in  connection  with any Plan  maintained,  at any time,  by any such
Person  or to which any such  Person  has or had at any time any  obligation  to
contribute,  or/and against any such Plan itself, or against any fiduciary of or
service  provided to any such Plan, and (ii) the  occurrence of any  "Reportable

in all respects with the Environmental Laws applicable to such Person except for
such non-  compliances  as singly or in the  aggregate,  could not reasonably be
expected to have a Materially Adverse Effect,  (ii) notify Lender promptly after
any  Credit  Party  becomes  aware of any  Release  upon any  premises  owned or
occupied  by such  Credit  Party that could  reasonably  be  expected  to have a
Materially  Adverse Effect or result in the incurrence by such Credit Party of a
material liability, actual or contingent, and (iii) promptly forward to Lender a
copy of any order, notice, permit,  application,  or any communication or report
received  by any  Credit  Party  in  connection  with  any  such  Release  or in
connection with any other matter relating to the Environmental Laws that, singly
or in the aggregate,  may adversely  affect the use or value of such premises in
any material respect.  The provisions of this Section 6.9 shall apply whether or
not the Environmental  Protection  Agency, any other federal agency or any state
or local  environmental  agency has taken or threatened any action in connection

access at any and all times),  to the  properties  and facilities of such Credit
Party;  (ii)  permit  Lender and any of its  officers,  employees  and agents to
inspect,  audit and make  extracts  from all of its records,  files and books of

Credit  Party's  locations and at premises not owned by or leased to such Credit
Party.  Each Credit Party shall make  available  to Lender and its  counsel,  as
quickly as practicable under the  circumstances,  copies of all books,  records,
board minutes,  contracts,  insurance policies,  environmental audits,  business
plans, files, financial statements (actual and pro forma), filings with federal,
state  and  local  regulatory  agencies,  and other  instruments  and  documents
(excluding  attorney-client  privileged documents) that Lender may request. Each
Credit Party shall deliver any document or instrument  reasonably  necessary for
Lender, as it may from time to time request,  to obtain records from any service
bureau or other Person which maintains  records for such Credit Party, and shall
maintain  duplicate  records or supporting  documentation  on media,  including,
without  limitation,  computer tapes and discs owned by such Credit Party.  Upon
the request of the Lender, each Credit Party shall instruct its certified public

Collateral  purported to be covered  thereby and that is deemed  material by the
Lender;  provided,  however,  that no  event  described  in  clause  (i) of this

provided to Lender under the Loan Documents  and/or at law or equity,  including

Obligations  shall  become  immediately  due and payable and any  obligation  on
Lender's  part to make any  further  Revolving  Credit  Advances or to incur any
further Letter of Credit  Obligations shall immediately  terminate,  all without
declaration, notice or demand by Lender.

                  8.3 Cumulative  Remedies.  Lender's  rights and remedies under
this  Agreement  shall be cumulative  and  nonexclusive  of any other rights and
remedies  which  Lender may have under any other  agreement,  including  without
limitation,  the Loan Documents,  by operation of law or otherwise.  Recourse to
the Collateral shall not be required.

                  8.4 Waivers by Borrower.  Except as otherwise  provided for in
this Agreement and to the fullest extent permitted by Applicable Law,  Borrower,
for itself and on behalf of each other  Credit  Party,  waives (i)  presentment,

exercise any of its remedies, and (iii) the benefit of all valuation,  appraisal
and exemption laws. Borrower acknowledges that it has been advised by counsel of
its choice with  respect to this  Agreement,  the other Loan  Documents  and the
transactions evidenced by this Agreement and the other Loan Documents.

                  9.3 Indemnity.

                  (a) Borrower shall indemnify and hold Lender and each of their
respective  Affiliates,  officers,  directors,  employees,  attorneys and agents
(each,  an "Indemnified  Person"),  harmless from and against any and all suits,
actions,   proceedings,   claims,  damages,  losses,  liabilities  and  expenses
(including  reasonable  attorneys' fees and  disbursements  and other reasonable
costs of  investigation  or defense,  including  those incurred upon any appeal)
that may be  instituted  or asserted  against or  incurred  by such  Indemnified
Person as the result of credit having been extended under this Agreement and the
other Loan  Documents or in connection  with or arising out of the  transactions
contemplated  hereunder  and  thereunder,  including  any claim,  action,  suit,
proceeding, loss, cost, damage, liability,  deficiency, fine, penalty, punitive,
exemplary or consequential damage or expense (including reasonable
- -51-
<PAGE>
attorneys' and consultants' fees, investigation and laboratory fees, court costs
and litigation expenses), directly or indirectly resulting from, arising out of,
or  based  upon  (i) the  presence,  Release,  use,  manufacture,  installation,
generation,  discharge,  storage  or  disposal,  at any time,  of any  Hazardous
Materials on, under, in or about, or the transportation of any such materials to
or from, any of the Subject Property, or (ii) the violation or alleged violation
by any Credit Party of any law, statute,  ordinance,  order,  rule,  regulation,
permit,  judgment  or  license  relating  to the use,  generation,  manufacture,
installation,  Release, discharge, storage or disposal of Hazardous Materials to
or from any of the Subject  Property;  which  indemnity  shall include,  without
limitation,  (A) any damage, liability,  fine, penalty,  punitive,  exemplary or
consequential  damage, cost or expense arising from or out of any claim, action,
suit or proceeding for personal injury (including sickness, disease, death, pain
or suffering),  tangible or intangible  property  damage,  compensation for lost
wages,  business income,  profits or other economic loss,  damage to the natural
resources or the environment, nuisance, pollution,  contamination, leak, Release
or other adverse effect on the environment,  and (B) the cost of any required or
necessary repair,  cleanup,  treatment,  remediation or detoxification of any of
the Subject  Property and the  preparation  and  implementation  of any closure,
disposal,  remedial  or other  required  actions in  connection  with any of the
Subject  Property;   provided,  that  Borrower  shall  not  be  liable  for  any
indemnification  to such  Indemnified  Person to the extent  that any such suit,
action,  proceeding,  claim,  damage,  loss, liability or expense results solely
from such Indemnified  Person's gross negligence or willful misconduct.  NEITHER
LENDER NOR ANY OTHER  INDEMNIFIED  PERSON SHALL BE  RESPONSIBLE OR LIABLE TO ANY
OTHER PARTY HERETO,  ANY SUCCESSOR,  ASSIGNEE OR THIRD PARTY BENEFICIARY OF SUCH
PERSON OR ANY OTHER PERSON ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR
INDIRECT,  PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES THAT MAY BE ALLEGED AS A
RESULT OF CREDIT HAVING BEEN EXTENDED UNDER THE LOAN DOCUMENTS.

                  (b) Borrower hereby acknowledges and agrees that Lender (i) is
not now, and has not ever been, in control of any of the Subject Property or the
affairs of Borrower,  and (ii) does not have the capacity through the provisions
of the Loan  Documents  to  influence  Borrower's  conduct  with  respect to the
ownership, operation or management of any of the Subject Property.

                  9.4 No  Waiver.  Lender's  failure,  at any time or times,  to
require  strict  performance  by  Borrower  or any  other  Credit  Party  of any
provision of this Agreement or any of the other Loan Documents  shall not waive,
affect or diminish any right of Lender  thereafter to demand  strict  compliance
and  performance  therewith.  Any  suspension or waiver of any Default under the
Loan Documents  shall not suspend,  waive or affect any other Default under this
Agreement  or any of the  other  Loan  Documents  whether  the  same is prior or
subsequent  thereto and whether of the same or of a different  type. None of the
undertakings,  agreements,  warranties,  covenants  and  representations  of any
Credit Party  contained in this Agreement or any of the other Loan Documents and
no Default by Borrower  under this Agreement and no defaults by any Credit Party
under any of the other Loan Documents  shall be deemed to have been suspended or
waived by Lender,  unless  such  waiver or  suspension  is by an  instrument  in
writing signed by an officer of or other authorized
- -52-
<PAGE>
employee of Lender and  directed  to  Borrower  specifying  such  suspension  or
waiver.

                  9.5 Successors and Assigns.  This Agreement and the other Loan
Documents  shall be  binding  on and shall  inure to the  benefit  of  Borrower,
Lender,  and their  respective  successors  and  assigns,  except  as  otherwise
provided herein or therein.  Borrower may not assign,  transfer,  hypothecate or
otherwise convey its rights, benefits,  obligations or duties hereunder or under
any of the other Loan  Documents  without the prior express  written  consent of
Lender.  Any  such  purported  assignment,   transfer,  hypothecation  or  other
conveyance by Borrower without the prior express written consent of Lender shall
be void.  The Lender may assign its rights and  obligations  hereunder to one or
more financial  institutions with the consent of the Borrower,  such consent not
to be  unreasonably  withheld  or  delayed.  The  terms and  provisions  of this
Agreement  and the other Loan  Documents  are for the  purpose of  defining  the
relative  rights and  obligations  of Borrower  and Lender  with  respect to the
transactions contemplated hereby and there shall be no third party beneficiaries
of any of the terms and  provisions  of this  Agreement or any of the other Loan
Documents.

                  9.6 Severability.  Wherever  possible,  each provision of this
Agreement  shall be  interpreted  in such a manner as to be effective  and valid
under applicable law, but if any provision of this Agreement shall be prohibited
by or invalid under  applicable  law, such provision shall be ineffective to the
extent of such prohibition or invalidity,  without invalidating the remainder of
such provision or the remaining provisions of this Agreement.

                  9.7 Conflict of Terms.  Except as  otherwise  provided in this
Agreement  or any of the other  Loan  Documents  by  specific  reference  to the
applicable  provisions of this  Agreement,  if any  provision  contained in this
Agreement is in conflict with, or inconsistent with, any provision in any of the
other Loan Documents, the provision contained in this Agreement shall govern and
control.

                  9.8  Authorized  Signature;  Oral  Instructions.  Until Lender
shall be notified by Borrower  to the  contrary,  each of the Persons  listed on
Schedule 9.8 (an "Authorized  Borrower  Representative") is authorized to act on
behalf  of the  Borrower  in all  respects  hereunder  and the  Lender  shall be
protected in all respect when acting in accordance  with  instructions  given by
such Person.  The signature upon any document or instrument  delivered  pursuant
hereto of any such  Person  shall bind  Borrower  and be deemed to be the act of
Borrower  affixed pursuant to and in accordance with resolutions duly adopted by
Borrower's Board of Directors.  The Lender has permitted telephonic instructions
hereunder  as  an   accommodation   to  the  Borrower.   In  exchange  for  such
accommodation,  the Borrower agrees that the Lender's  understanding of any oral
instruction  shall be binding and conclusive upon the Borrower,  notwithstanding
any divergence  between such  understanding  and any later written  confirmation
thereof,  and the Lender shall in all respects be  protected  and held  harmless
when acting in accordance with such understanding, it being the intention of the
parties that the Borrower assume all risks of the use of oral communication.

                  9.9 Governing Law. EXCEPT AS OTHERWISE  EXPRESSLY  PROVIDED IN
ANY  OF  THE  LOAN  DOCUMENTS,  IN  ALL  RESPECTS,   INCLUDING  
- -53-

ALL MATTERS OF CONSTRUCTION,  VALIDITY AND  PERFORMANCE,  THIS AGREEMENT AND THE
OBLIGATIONS  ARISING  HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED

DOCUMENTS OR TO ANY MATTER  ARISING OUT OF OR RELATING TO THIS  AGREEMENT OR ANY
OF THE OTHER LOAN DOCUMENTS, PROVIDED, THAT LENDER AND BORROWER ACKNOWLEDGE THAT
ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF
THE CITY AND STATE OF NEW YORK,  BOROUGH OF MANHATTAN  AND,  PROVIDED,  FURTHER,
THAT  NOTHING IN THIS  AGREEMENT  SHALL BE DEEMED OR OPERATE TO PRECLUDE  LENDER
FROM  BRINGING  SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER  JURISDICTION  TO

PROCEEDING  BROUGHT  BY THE  LENDER  IN ANY SUCH  OTHER  JURISDICTION.  BORROWER
EXPRESSLY  SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR
SUIT COMMENCED IN ANY SUCH COURT,  AND BORROWER HEREBY WAIVES ANY OBJECTION THAT
BORROWER MAY HAVE BASED UPON LACK OF PERSONAL  JURISDICTION,  IMPROPER  VENUE OR
FORUM NON  CONVENIENS  AND  HEREBY  CONSENTS  TO THE  GRANTING  OF SUCH LEGAL OR
EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT.  BORROWER HEREBY WAIVES
PERSONAL SERVICE OF THE SUMMONS,  COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH

provided.  The giving of any notice required  hereunder may be waived in writing
by the party  entitled to receive  such notice.  Failure or delay in  delivering
copies of any notice, demand, request, consent,  approval,  declaration or other
communication to any Person (other than Borrower or Lender)  designated above to
receive  copies  shall in no way  adversely  affect  the  effectiveness  of such
notice, demand, request, consent, approval, declaration or other communication.

                  9.11  Subordination.  As  an  independent  covenant,  Borrower
hereby expressly covenants and agrees for the benefit of Lender that all present
or future indebtedness, obligations and liabilities of any other Credit Party to
Borrower of whatsoever description (collectively,  the "Junior Claims") shall be
subordinate  and junior in right of payment to all  Obligations,  effective upon
the occurrence and during the continuance of an Event of Default. If an Event of
Default  shall occur,  then,  unless and until such Event of Default  shall have
been cured or shall have  ceased to exist,  no direct or  indirect  payment  (in
cash, property,  securities, by set-off or otherwise) shall be made by any other
Credit Party to Borrower on account of or in any manner in respect of any Junior
Claim  except such  payments  and  distributions  the proceeds of which shall be
applied  to the  Obligations.  In the  event  of a  Proceeding  (as  hereinafter
defined),  all  Obligations  shall  first be paid in full  before  any direct or
indirect payment or distribution (in cash, property,  securities,  by set-off or
otherwise)  shall be made to  Borrower on account of or in any manner in respect
of any Junior Claim except such payments and distributions the proceeds of which
shall be applied to the Obligations.  For the purposes of the previous sentence,
a "Proceeding"  shall occur if any Credit Party shall make an assignment for the
benefit of creditors, file a petition in bankruptcy,  have entered against or in
favor of it an order for relief under the Bankruptcy  Code or similar law of any
other jurisdiction,  generally fail to pay its debts as they come due (either as
to number or amount),  admit in writing its inability to pay its debts generally
as they  mature,  make a  voluntary  assignment  for the  benefit of  creditors,
commence any proceeding  relating to it under any  reorganization,  arrangement,
readjustment  of  debt,  dissolution  or  liquidation  law  or  statute  of  any
jurisdiction,  whether now or hereafter in effect,  or by any act,  indicate its
consent  to,  approval  of or  acquiescence  in any  such  proceeding  or in the
appointment  of any  receiver  of, or trustee or  custodian  (as  defined in the
Bankruptcy  Code) for itself,  or any  substantial  part of its  property,  or a
trustee  or a  receiver  shall  be  appointed  for  any  Credit  Party  or for a
substantial  part of the property of any Credit Party,  or a petition  under any
bankruptcy,  reorganization,  arrangement,  readjustment of debt, dissolution or
liquidation  law or statute or any  jurisdiction  (whether  now or  hereafter in
effect)  shall be filed  against  any Credit  Party.  In the event any direct or
indirect  payment or distribution is made to Borrower in  contravention  of this
Section,  such payment or distribution shall be deemed received in trust for the
benefit of Lender and shall be immediately  paid over to Lender for  application
against the Obligations. Borrower agrees to execute such additional documents as
Lender may reasonably request to evidence the subordination provided for in this
Section.

                  9.12 Survival of  Obligations  Upon  Termination  of Financing
Arrangement.  Except as otherwise  expressly provided for in the Loan Documents,
no  termination  or  cancellation  (regardless  or  cause or  procedure)  of any
financing arrangement under this Agreement shall in any way affect or impair the
obligations, duties and liabilities of
- -56-
<PAGE>
Borrower or the rights of Lender relating to any unpaid  Obligation,  due or not
due,  liquidated,  contingent  or  unliquidated  or  any  transaction  or  event
occurring  prior  to  such  termination,   or  any  transaction  or  event,  the
performance of which is not required until after the Termination Date. Except as
otherwise  expressly  provided  herein  or  in  any  other  Loan  Document,  all
undertakings,  agreements,  covenants,  warranties  and  representations  of  or
binding upon  Borrower,  and all rights of Lender,  all as contained in the Loan
Documents  shall  not  terminate  or  expire,  but  rather  shall  survive  such
termination  or  cancellation  and shall continue in full force and effect until
such  time as all of the  Obligations  have  been  indefeasibly  paid in full in
accordance with the terms of the agreements creating such Obligations, provided,
however,  that the  Lender  agrees to take such  action  as the  Borrower  shall
reasonably request, at the Borrower's cost and expense, to file such instruments
as shall be  necessary  to  release  its  Liens  under the Loan  Documents  upon
termination of the  Commitment  and receipt by the Lender of collected  funds in
the amount of the outstanding Obligations.

                  9.13 Section Titles.  The Section titles and Table of Contents
contained  in this  Agreement  are and shall be without  substantive  meaning or
content of any kind  whatsoever and are not a part of the agreement  between the
parties hereto.

                  9.14  Counterparts.  This  Agreement  may be  executed  in any
number of separate counterparts, each of which shall collectively and separately
constitute one agreement.

                  9.15 Time of Essence. Time is of the essence of this Agreement
and each of the other Loan Documents.

                  9.16  Waiver  of  Jury  Trial.  BECAUSE  DISPUTES  ARISING  IN
CONNECTION WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY
RESOLVED BY AN  EXPERIENCED  AND EXPERT  PERSON AND THE PARTIES WISH  APPLICABLE
STATE AND FEDERAL LAWS TO APPLY  (RATHER THAN  ARBITRATION  RULES),  THE PARTIES
DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS.
THEREFORE,  TO ACHIEVE THE BEST  COMBINATION  OF THE  BENEFITS  OF THE  JUDICIAL
SYSTEM AND OF  ARBITRATION,  THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY
IN ANY ACTION,  SUIT,  OR  PROCEEDING  BROUGHT TO RESOLVE ANY  DISPUTE,  WHETHER
SOUNDING IN CONTRACT,  TORT, OR OTHERWISE,  BETWEEN LENDER AND BORROWER  ARISING
OUT  OF,  CONNECTED  WITH,   RELATED  TO,  OR  INCIDENTAL  TO  THE  RELATIONSHIP
ESTABLISHED  BETWEEN THEM IN CONNECTION WITH, THIS AGREEMENT OR ANY OF THE OTHER
LOAN DOCUMENTS OR THE TRANSACTIONS RELATED THERETO.

                  9.17  Syndication.  The Borrower  agrees to take such steps as
the  Lender  shall  reasonably  request  to  assist  Lender  in the sale  and/or
syndication  of the  credit  provided  herein  to one or  more  other  financial
institutions.  Such steps may include,  at the  discretion,  
- -57-
<PAGE>
of the  Lender,  the  preparation  and  dissemination  of  financial  and  other
disclosure documents to prospective  purchasers,  discussions by management with
such Persons and such  amendments to the Loan  Documents as shall be required to
cause them to conform with customary syndicated bank documents.

                  9.18  Special   Provision   Relating  to  this  Amendment  and
Restatement.

one  original  and shall be  binding  upon all  parties,  their  successors  and
permitted assigns.

                  (c) References to the Original Agreement contained in any Loan
Document  shall be deemed to be a  reference  to such  agreement  as amended and

                  (d)  Borrower  hereby  acknowledges  that  the  Note  and  the
Collateral Documents previously executed and delivered by Borrower to Lender are
and shall  remain in full force and effect,  and hereby  ratifies,  confirms and
approves  the  Note and  such  Collateral  Documents  and all of the  terms  and
provisions  thereof,  and  agrees  that the  Note  and  each of such  Collateral
Documents constitutes the valid and binding obligation of Borrower,  enforceable
by the Lender in accordance with its terms.

                                 SCHEDULE 2.1(g)
                                       to
                                CREDIT AGREEMENT
                           Dated as of April 11, 1994
                   As Amended and Restated as of June 11, 1997

          (a)  Lender  agrees,  subject  to  the  terms  and  conditions  of the
Agreement,  to incur from time to time prior to the Commitment Termination Date,
upon written  request of Borrower,  Letter of Credit  Obligations  in respect of
Letters of Credit;  provided,  however, that (i) Lender shall have no obligation
to incur any further  Letter of Credit  Obligations  on or after the  Commitment
Termination  Date,  (ii) each  Letter of Credit  shall be in form and  substance
satisfactory  to Lender and,  without  limiting the generality of the foregoing,
unless the Lender shall otherwise consent in writing,  no Letter of Credit shall
have an expiry date which is more than one year  following  the date of issuance
thereof  and  Lender  shall be under no  obligation  to incur  Letter  of Credit
Obligations  in respect of any Letter of Credit  having an expiry  date which is
later than the Commitment  Termination  Date,  which shall be presumed to be the
Maturity  Date  unless the Lender  shall  have given or  received  notice to the
contrary  as  permitted  pursuant  to  the  Credit  Agreement,   and  (iii)  the
determination of the bank or other legally  authorized Person (including Lender)
which shall issue any Letter of Credit  contemplated by this paragraph (a) shall
be made by Lender,  in its sole discretion.  Each request by Borrower for Lender
to incur a Letter of Credit  Obligation  shall be  substantially  in the form of
Exhibit A hereto,  shall specify the amount of such Letter of Credit  Obligation
and provide such other  information  with respect  thereto as may be required by
Lender, shall be given in writing (by telecopy,  telex or cable) or by telephone
confirmed  immediately  in  writing,  and  shall be given not less than ten (10)
Business Days prior to the requested date for Lender's  incurring such Letter of
Credit Obligation.  Each Letter of Credit Obligation incurred by Lender shall be
substantially  in the form of Exhibit B attached hereto or in such other form as
may be acceptable to Lender.

          (b) Borrower hereby irrevocably, absolutely and unconditionally agrees
to  reimburse  Lender on demand  for the amount of any and all  payments  now or
hereafter  made by Lender on or  pursuant  to any  Letter of Credit  Obligations
incurred  by  Lender.  In the event the  Lender  shall  make any  payment  on or
pursuant to any Letter of Credit  Obligation  incurred by Lender,  such  payment
shall  then be deemed to  constitute  a  Revolving  Credit  Advance by Lender to
Borrower under Section 2.1(a) of the Credit Agreement.

          (c) (i) In the event that any Letter of Credit Obligation  incurred by
Lender, whether or not then due and payable, shall for any reason be outstanding
on the  Commitment  Termination  Date,  Borrower will pay to Lender cash or cash
equivalents acceptable to Lender ("Cash Equivalents") in an amount equal to 105%
of the maximum amount then available to be drawn under the applicable Letters of
Credit.  Such  funds  or Cash  Equivalents  shall  be held by  Lender  in a cash
collateral account (the "Cash Collateral  Account")  maintained in Bankers Trust
Company,  New York, New York (or at such other depository  institution as may be
selected by Lender).  The Cash Collateral Account shall be in the name of Lender
(as a cash collateral account), and shall be under the sole dominion and control
of Lender and
<PAGE>
subject to the terms of this  Schedule  2.1(g).  Borrower  hereby  pledges,  and
grants to Lender a security  interest  in,  all such funds and Cash  Equivalents
held in the Cash Collateral  Account from time to time and all proceeds thereof,
as  security  for the  payment  of all  amounts  due in respect of the Letter of
Credit  Obligations  and all other  Obligations,  whether  or not then due.  The
Agreement shall constitute a security agreement under applicable law.

          (ii)  From  time  to  time  after  funds  are  deposited  in the  Cash
Collateral Account, Lender may apply such funds or Cash Equivalents then held in
the Cash  Collateral  Account to the  payment of any  amounts,  in such order as
Lender may elect,  as shall be or shall  become due and  payable by  Borrower to
Lender  with  respect  to  such  Letter  of  Credit  Obligations  or  any  other
Obligations which may be then outstanding.

          (iii) Neither Borrower nor any Person claiming on behalf of or through
Borrower  shall have any right to withdraw any of the funds or Cash  Equivalents
held in the Cash  Collateral  Account,  except that upon the  termination of all
Letter of Credit  Obligations and the payment of all amounts payable by Borrower
to Lender in respect thereof and in respect of all other Obligations,  any funds
remaining in the Cash Collateral  Account in excess of the then remaining Letter
of Credit Obligations shall be returned to Borrower.

          (iv) Lender shall not have any  obligation  to invest the funds in the
Cash Collateral  Account or deposit such funds in any interest  bearing account,
and interest and earnings thereon, if any, shall be the property of Lender.

     (d) In the event that Lender  shall  incur any Letter of Credit  Obligation
pursuant hereto at the request or on behalf of Borrower,  Borrower agrees to pay
to Lender,  as  compensation  to Lender for such Letter of  Obligation,  (i) all
costs  and  expenses  incurred  by Lender on  account  of such  Letter of Credit
Obligation  and (ii)  commencing  with the month in which such  Letter of Credit
Obligation  is incurred by Lender and monthly  thereafter  for each month during
which such Letter of Credit  Obligation  shall remain  outstanding,  a fee in an
amount equal to two percent (2%) per annum of the maximum amount  available from
time to time to be drawn under the  applicable  Letter of Credit,  calculated on
the basis of a 360-day  year and the actual  number of days  elapsed;  provided,
however,  that so long as any  Default or Event of Default has  occurred  and is
continuing,  such letter of credit fee rate may be increased  by Lender,  in its
discretion,  by up to an additional two percentage  points (2.0%) above the rate
otherwise applicable. Fees payable by Borrower to Lender hereunder in respect of
Letter of Credit Obligations  (collectively,  the "Letter of Credit Fees") shall
be paid to  Lender  in  arrears,  on the  first  day of  each  month  and on the
Commitment  Termination  Date and  thereafter  on  demand.  The fees,  costs and
expenses  provided for in this paragraph (d) are in addition to any fees,  costs
and expenses payable to the issuers of the Letters of Credit, all of which shall
be  solely  for the  account  of  Borrower  and shall be paid or  reimbursed  by
Borrower.

     (e)  Borrower's  Obligations to Lender with respect to any Letter of Credit
or Letter of Credit  Obligation  shall be evidenced by Lender's  records and, in
the absence of manifest error, shall be absolute,  unconditional and irrevocable
and shall not be affected, modified or 
                                      -2-
<PAGE>
impaired  by: (i) any lack of validity  or  enforceability  of the  transactions
contemplated  by or  related  to such  Letter  of  Credit  or  Letter  of Credit
Obligation; (ii) any amendment or waiver of or consent to depart from all or any
of the terms of the  transactions  contemplated  by or related to such Letter of
Credit or  Letter  of Credit  Obligation;  (iii)  the  existence  of any  claim,
set-off,  defense or other right which  Borrower or any other  Credit  Party may
have against Lender,  the issuer or beneficiary of such Letter of Credit, or any
other  Person,  whether in  connection  with the  Agreement or the  transactions
contemplated  therein or such Letter of Credit or the transactions  contemplated
thereby or any  unrelated  transactions,  provided  however that this  provision
shall not be deemed to  prevent  Borrower  from  pursuing  any claim it may have
against  Lender or the  issuer of any  Letter of Credit by  separate  proceeding
following the payment of any such  Obligation  or from  pursuing any  compulsory
counterclaim in any civil action filed in respect thereof; or (iv) the fact that
any draft,  affidavit,  letter,  certificate,  invoice,  bill of lading or other
document  presented  under or delivered in connection with such Letter of Credit
or any other Letter of Credit proves to have been forged, fraudulent, invalid or
insufficient in any respect or any statement  therein proves to have been untrue
or incorrect in any respect.  Nothing in this  paragraph  (e) shall be deemed to
create any right in any Person other than the Lender.

     (f) In addition to any other indemnity  obligations which Borrower may have
to Lender under the  Agreement and without  limiting such other  indemnification
provisions,  Borrower hereby agrees to indemnify  Lender from and to hold Lender
harmless  against any and all claims,  liabilities,  losses,  costs and expenses
(including,  without limitation,  attorney's fees and expenses) which Lender may
(other than as a result of its own gross negligence or willful misconduct) incur
or be subject to as a consequence,  directly or indirectly,  of (i) the issuance
of or  payment  of or  failure  to pay under  any  Letter of Credit or Letter of
Credit  Obligation  or (ii) any suit,  investigation  or  proceeding as to which
Lender is or may become a party as a consequence, directly or indirectly, of the
issuance  of any  Letter  of  Credit,  the  incurring  of any  Letter  of Credit
Obligation  or any  payment  of or  failure to pay under any Letter of Credit or
Letter of Credit  Obligation.  The  obligations of Borrower under this paragraph
shall survive any termination of the Agreement.

     (g) Borrower  hereby assumes all risks of the acts,  omissions or misuse of
each Letter of Credit by the  beneficiary  or issuer  thereof and, in connection
therewith,  Lender shall not be responsible  (i) for the validity,  sufficiency,
genuineness  or legal effect of any document  submitted in  connection  with any
drawing  under  any  Letter of  Credit  even if it  should in fact  prove in any
respect to be invalid,  insufficient,  inaccurate, untrue, fraudulent or forged;
(ii) for the validity or sufficiency of any instrument transferring or assigning
or  purporting  to  transfer  or assign  any  Letter of Credit or any  rights or
benefits  thereunder or any proceeds  thereof,  in whole or in part,  even if it
should prove to be invalid or ineffective for any reason;  (iii) for the failure
of any issuer or  beneficiary  of any Letter of Credit to comply  fully with the
terms thereof including without  limitation the conditions  required in order to
effect  or  pay  a  drawing   thereunder;   (iv)  for  any  errors,   omissions,
interruptions  or delays in transmission  or delivery of any messages,  by mail,
telecopy,  telex or otherwise;  (v) for any loss or delay in the transmission or
otherwise of any document or draft required in order to make a drawing under any
Letter of Credit;  or (vi) for any  consequences  arising from causes beyond the

Additional  Pledged Stock  accompanied  by undated stock powers duly executed in
blank by the Pledgor and all certificates  and instruments  evidencing the items
described  in clauses (i) and (ii) above  promptly  upon the  Pledgor's  receipt
thereof.

             (d) The Pledged  Stock and all items  described in  subsection  (c)
above are  hereinafter  called  the  "Additional  Pledged  Securities,"  and the
Additional  Pledged  Securities,  together with all other  securities and moneys
received and at the time held by the Lender  hereunder  and any cash or non-cash
proceeds  of  any of the  foregoing,  are  hereinafter  called  the  "Additional
Collateral."  For all  purposes  of the  Pledge  Agreement,  the  term  "Pledged
Securities"  shall mean and  include  the  Pledged  Securities  of the  Borrower
initially pledged thereunder and the Additional Pledged Securities, and the term
"Collateral" shall mean and include the Collateral  initially pledged thereunder
and the Additional Collateral.

             2. Subordination.  As an independent  covenant,  the Pledgor hereby
expressly covenants and agrees for the benefit of the Lender that all present or
future  indebtedness,  obligations  and liabilities of any other Credit Party to
the Pledgor of whatsoever description (collectively,  the "Junior Claims") shall
be subordinate and junior in right of payment to all Obligations, effective upon
the occurrence and during the continuance of an Event of Default. If an Event of
Default  shall occur,  then,  unless and until such Event of Default  shall have
been cured or shall have  ceased to exist,  no direct or  indirect  payment  (in
                                       -2-
<PAGE>
cash, property,  securities, by set-off or otherwise) shall be made by any other
Credit  Party to the  Pledgor  on  account of or in any manner in respect of any
Junior Claim except such payments and  distributions the proceeds of which shall
be applied to the  Obligations.  In the event of a  Proceeding  (as  hereinafter
defined),  all  Obligations  shall  first be paid in full  before  any direct or
indirect payment or distribution (in cash, property,  securities,  by set-off or
otherwise)  shall be made to the  Pledgor  on  account  of or in any  manner  in
respect of any Junior Claim except such payments and  distributions the proceeds
of which shall be applied to the  Obligations.  For the purposes of the previous
sentence,  a  "Proceeding"  shall  occur  if any  Credit  Party  shall  make  an
assignment  for the benefit of creditors,  file a petition in  bankruptcy,  have
entered  against or in favor of it an order for relief under the Bankruptcy Code
or similar  law of any other  jurisdiction,  generally  fail to pay its debts as
they come due (either as to number or amount), admit in writing its inability to
pay its debts  generally as they  mature,  make a voluntary  assignment  for the
benefit  of  creditors,  commence  any  proceeding  relating  to  it  under  any
reorganization,  arrangement,  readjustment of debt,  dissolution or liquidation
law or statute of any  jurisdiction,  whether now or hereafter in effect,  or by
any act,  indicate  its consent  to,  approval  of or  acquiescence  in any such
proceeding or in the appointment of any receiver of, or trustee or custodian (as
defined in the  Bankruptcy  Code) for  itself,  or any  substantial  part of its
property,  or a trustee or a receiver shall be appointed for any Credit Party or
for a substantial  part of the property of any Credit Party, or a petition under
any bankruptcy,  reorganization,  arrangement, readjustment of debt, dissolution
or liquidation law or statute or any  jurisdiction  (whether now or hereafter in
effect)  shall be filed  against  any Credit  Party.  In the event any direct or
indirect payment or distribution is made to the Pledgor in contravention of this
Section,  such payment or distribution shall be deemed received in trust for the
benefit  of the  Lender  and shall be  immediately  paid over to the  Lender for
application  against  the  Obligations.  The  Pledgor  agrees  to  execute  such
additional  documents  as the Lender may  reasonably  request  to  evidence  the
subordination provided for in this Section.

             3. No Other  Amendments.  Except for the  amendments  expressly set
forth and referred to above,  the Pledge Agreement shall remain unchanged and in
full  force and  effect.  Nothing in this  Amendment  is  intended,  or shall be
construed,  to constitute a novation or an accord and satisfaction of any of the
Pledgor's  obligations  under or in connection with the Pledge  Agreement or any
other Loan Document or to modify,  affect or impair the perfection or continuity
of the Lender's security  interests in, security titles to or other liens on any
Collateral for the Obligations.

             4.  Representations and Warranties.  To induce Lender to enter into
this  Amendment,  the Pledgor  does hereby  warrant,  represent  and covenant to
Lender that: (a) each representation or warranty of the Pledgor set forth in the
Pledge  Agreement,  as  amended  by  this  Amendment,  is  hereby  restated  and
reaffirmed  as true and correct in all  material  respects on and as of the date
hereof (except to the extent that any such  representation or warranty expressly
relates to a prior specific date or period),  and no Default or Event of Default
has  occurred  and is  continuing  as of this date as  defined  under the Credit
Agreement;  and (b) the  Pledgor has the power and is duly  authorized  to enter
into, deliver and perform this Amendment, and this Amendment is the legal, valid
and binding obligation of the Pledgor  enforceable against it in accordance with
its terms  except to the extent  that such  enforceability  may be  effected  by
bankruptcy, insolvency, reorganization, moratorium or other similar laws 
                                      -3-
<PAGE>
affecting the rights and remedies of creditors generally, and general principles
of equity.

             5.  Covenants.  The  Pledgor  shall  deliver  to  the  Lender  upon
execution of this Amendment,  the share certificates  representing the shares of
issued  and  outstanding  capital  stock  of  each  of  the  Additional  Pledged
Subsidiaries  pledged  hereunder,  together with an  irrevocable  stock transfer
power covering such shares.

             6.  Counterparts.  This  Amendment  may  be  executed  in  multiple
counterparts,  each of which shall be deemed to be an original  and all of which
when taken together shall constitute one and the same instrument.

             7.  Governing  Law.  THIS  AMENDMENT  SHALL  BE  GOVERNED  BY,  AND
CONSTRUED  IN  ACCORDANCE  WITH,  THE  INTERNAL  LAWS OF THE  STATE  OF NEW YORK
APPLICABLE TO CONTRACTS MADE AND PERFORMED IN SUCH STATE.

             8. Binding  Effect.  This Amendment shall be binding upon and shall
inure to the benefit of the parties hereto and their  respective  successors and
assigns.

             IN WITNESS  WHEREOF,  the parties hereto have caused this Amendment
to be duly  executed  and  delivered  as of the day and  year  specified  at the
beginning hereof.

                               SECURITY AGREEMENT

             SECURITY  AGREEMENT,  dated as of June 11,  1997,  made by ENHANCED
SYSTEMS, INC., an Arizona corporation, having its chief executive office at 8300
East Raintree Drive, Scottsdale,  Arizona 85260 ("Debtor"),  in favor of GENERAL
ELECTRIC CAPITAL  CORPORATION,  a New York corporation  having an office at 1999
Avenue of the Stars, 30th Floor, Los Angeles, California 90067 ("Lender").

                              W I T N E S S E T H:

             WHEREAS,  pursuant  to that  certain  Amended and  Restated  Credit
Agreement  dated  as of April  11,  1994,  by and  among  Vodavi  Communications
Systems, Inc., an Arizona corporation formerly known as V Technology Acquisition
Corp.  ("Borrower") and Lender,  as amended and restated as of June 11, 1997 (as
the same from time to time may be amended,  restated,  supplemented or otherwise
modified,  the "Credit  Agreement"),  Lender has agreed,  among other things, to
make a certain  Revolving  Credit  Loan (as  defined  in the  Credit  Agreement)
available to Borrower; and

             WHEREAS,  pursuant to that certain Guaranty Agreement,  dated as of
June 11, 1997, executed by Debtor and Arizona Repair Services,  Inc. in favor of
Lender  (the  "Guaranty  Agreement"),  Debtor has  guaranteed  the  payment  and
performance by Borrower of all obligations of Borrower  arising under the Credit
Agreement  (including  without limitation payment of the Revolving Credit Loan);
and

             WHEREAS,  Lender is willing to make the  Revolving  Credit Loan and
any other extension of credit provided for in the Credit Agreement  available to
Borrower,  but only upon the  condition,  among  others,  that Debtor shall have
executed and delivered this Security Agreement in favor of Lender; and

             NOW,  THEREFORE,  in consideration of the premises and the Lender's
commitment to make the Revolving Credit Loan available to Borrower,  the parties
hereto agree as follows:

             1. DEFINED TERMS.  Unless  otherwise  defined  herein,  capitalized
terms defined in the Credit Agreement are used herein as therein defined.

             2. GRANT OF SECURITY INTEREST.

             a. To secure the  prompt  and  complete  payment,  performance  and
observance of all of the  obligations,  indebtedness  and  liabilities of Debtor
under the Guaranty Agreement (collectively,  the "Secured Obligations"),  and to
induce Lender to enter into the Credit Agreement, to issue the Commitment and to
make the Revolving  Credit Loan and any other  extensions of credit provided for
therein  available to Borrower in accordance with the respective  terms thereof,
Debtor  hereby  grants to Lender a security  interest in all of Debtor's  right,
title and interest in, to and under the following  whether now owned by or owing
to, or hereafter acquired by or arising in favor of Debtor  (including,  without
limitation, under any trade names, styles or
<PAGE>
divisions  thereof),  and  regardless  of  where  located  (all of  which  being
hereinafter collectively referred to as the "Collateral"):

                    (i) all Accounts;

                    (ii) all Chattel Paper;

                    (iii) all Contracts;

                    (iv) all Documents;

                    (v) all Equipment;

                    (vi) all General Intangibles;

                    (vii) all Instruments;

                    (viii) all Inventory;

                    (ix) all other money, cash or cash equivalents of Debtor;

                    (x) all  books and  records  (including  without  limitation
             credit files,  customer lists,  computer files,  computer programs,
             computer   printouts,   or  other  computer   material)  of  Debtor
             identifying,  evidencing  or  otherwise  pertaining  to  any of the
             Collateral described above; and

                    (xi) all Proceeds of any of the Collateral described above.

             b.  In  addition,  to  secure  the  prompt  and  complete  payment,
performance  and  observance of the Secured  Obligations  and in order to induce
Lender as aforesaid,  Debtor hereby grants to Lender, a security interest in all
property of Debtor held by Lender, including,  without limitation,  all property
of every  description,  now or hereafter in the  possession  or custody of or in
transit to Lender for any purpose, including safekeeping,  collection or pledge,
for the account of Debtor, or as to which Debtor may have any right or power.

             3. LENDER'S RIGHTS; LIMITATIONS ON LENDER'S SECURED 
                OBLIGATIONS.

             a. It is expressly  agreed by Debtor that,  anything  herein to the
contrary notwithstanding, Debtor shall remain liable under each of its Contracts
and  each  of its  Licenses  to  observe  and  perform  all the  conditions  and
obligations  to be observed and performed by it thereunder and Lender shall have
no obligation or liability under any Contract or License by reason of or arising
out of this  Security  Agreement or the granting  herein of a security  interest
therein or the  receipt by Lender of any  payment  relating  to any  Contract or
License pursuant hereto, nor shall Lender be required or obligated in any manner
to perform or fulfill any of the  obligations of Debtor under or pursuant to any
Contract or License,  or to make any  payment,  or to make any inquiry as to the
nature or the sufficiency of any payment received by it or the
                                       -2-
<PAGE>
sufficiency of any performance by any party under any Contract or License, or to
present or file any  claims,  or to take any  action to  collect or enforce  any
performance  or the payment of any amounts which may have been assigned to it or
to which it may be entitled at any time or times.

             b.  Lender  may at any time  after the  occurrence  and  during the
continuation  of an Event of Default and upon 24 hours  prior  notice to Debtor,
notify Account  Debtors,  parties to the  Contracts,  and obligors in respect of
Instruments,  that the Accounts  and the right,  title and interest of Debtor in
and under such Contracts and  Instruments  have been assigned to Lender and that
payments  shall be made  directly  to  Lender,  and upon the  request of Lender,
Debtor shall so notify Account  Debtors,  parties to Contracts,  and obligors in
respect of  Instruments.  Lender may at any time after the occurrence and during
the continuation of an Event of Default and upon notice to the Debtor (which may
be  simultaneous  with notice to Obligors on chattel  paper) notify  obligors in
respect of Chattel  Paper that the right,  title and  interest  of Debtor in and
under such Chattel Paper have been assigned to Lender and that payments shall be
made directly to Lender.

             c.  Lender  at  any  time  after  the  occurrence  and  during  the
continuation  of an  Event  of  Default  shall  have  the  right  to  make  test
verifications  of the Accounts and  verifications  and  appraisals  of the other
Collateral  in any manner and through any medium  that it  reasonably  considers
advisable,  and Debtor agrees to furnish all such  assistance and information as
Lender may reasonably  require in connection  therewith.  Lender may at any time
after the  occurrence  and during the  continuation  of an Event of Default,  in
Lender's own name or in the name of Debtor,  communicate  with Account  Debtors,
parties to Contracts, obligors in respect of Instruments and obligors in respect
of Chattel  Paper to verify with such  Persons,  to Lender's  satisfaction,  the
existence,  amount and terms of any such  Accounts,  Contracts,  Instruments  or
Chattel  Paper.  Upon the occurrence  and  continuation  of an Event of Default,
Debtor,  at its own expense,  shall cause the certified  public  accountant then
engaged by Debtor, to prepare and deliver to Lender at any time and from time to
time promptly upon Lender's request the following reports:  (i) a reconciliation
of all Accounts, (ii) an aging of all Accounts, (iii) trial balances, and (iv) a
test verification of such Accounts as Lender reasonably may request.

             4.  REPRESENTATIONS  AND WARRANTIES.  Debtor hereby  represents and
warrants that:

             a. Except for the  security  interest  granted to Lender under this
Security  Agreement,  and the  Liens  set forth on  Schedule  7.6 to the  Credit
Agreement and Permitted Exceptions, Debtor is the sole owner of each item of the
Collateral in which it purports to grant a security interest  hereunder,  having
good and marketable title thereto free and clear of any and all liens,  security
interests or other encumbrances.

             b. No effective security agreement, financing statement, equivalent
security or lien instrument or continuation  statement  covering all or any part
of the Collateral is on file or of record in any public office, except as may be
set forth on Schedule 7.6 to the Credit Agreement or such as may have been filed
by Debtor in favor of Lender pursuant to this Security Agreement.

             c. As a result of the filing of appropriate financing statements in
the filing  offices  listed on Schedule I hereto,  this  Security  Agreement  is
effective to create a valid and
                                       -3-
<PAGE>
continuing  lien on and  perfected  security  interest in favor of Lender in the
Collateral with respect to which a security  interest may be perfected by filing
pursuant  to the UCC,  which lien and  security  interest  is prior to all other
Liens,  except only for Liens  specifically  designated on Schedule 7.6 as being
prior to Lender's Liens and Permitted  Prior  Exceptions,  and is enforceable as
such as against  creditors of and purchasers  from Debtor (other than purchasers
of  Inventory  in the  ordinary  course of  business).  All action  necessary or
desirable  to protect and  perfect  such  security  interest in each item of the
Collateral has been duly taken.

             d. Schedule II hereto lists all  Instruments of Debtor.  All action
necessary or desirable to protect and perfect the security interest of Lender in
each item set forth on Schedule  II,  including  the  delivery of all  originals
thereof to Lender,  has been duly taken. The security  interest of Lender in the
Collateral listed on Schedule II hereto is prior to all other Liens except those
Liens  specifically  designated on Schedule 7.6 as being prior to Lender's Liens
and Permitted Prior  Exceptions and is enforceable as such against  creditors of
and purchasers from Debtor.

             e. Debtor's chief  executive  office,  principal place of business,
corporate offices, all warehouses and premises within which Collateral is stored
and located and the locations of all of its records  concerning  the  Collateral
are set  forth  on the  Credit  Party  Questionnaire  completed  by  Debtor  and
delivered  to Lender,  and Debtor shall not change its chief  executive  office,
principal  place of business,  corporate  offices or  Collateral  locations,  or
remove such records unless it shall have notified the Lender in writing at least
30 days prior to such  change  and shall  have  taken such  action as the Lender
deems  reasonably  necessary  to cause the Lien of Lender in the  Collateral  to
continue to be perfected.

             f.  During  the  five (5) year  period  preceding  the date of this
Agreement,  Debtor has not been known as or used and Debtor  presently  does not
use any corporate  name other than its name as set forth in its signature  below
and  those  other  corporate,  fictitious  or trade  names (if any) of Debtor as
disclosed on the Credit Party Questionnaire completed by Debtor and delivered to
Lender.  If such  schedule  sets forth any  fictitious or trade names for Debtor
(collectively,  the "Trade Names"), Debtor represents and warrants to and agrees
with Lender that: (i) any  Collateral  arising out of any sales under any of the
Trade Names is the  property  of and  belongs to Debtor,  (ii) each of the Trade
Names  is a trade  name or  trade  style  (and not an  independent  or  separate
corporation or other legal entity) by which Debtor may identify or market itself
or under which  Debtor may sell certain  products,  render  certain  services or
otherwise conduct some or all of its business, (iii) any Collateral which arises
from any sales made,  services rendered or other business conducted under any of
the Trade Names shall be owned solely by Debtor, and (iv) Debtor hereby appoints
Lender to be its attorney-in-fact to file such certificates  disclosing Debtor's
use of the Trade  Names and to take such  other  actions on  Debtor's  behalf as
Lender  reasonably  considers   appropriate  to  comply  with  any  statutes  or
regulations relating to the use of fictitious or assumed business names.
                                       -4-
<PAGE>
             g. (i) The  Accounts  represent  bona fide  sales of  Inventory  or
services  rendered  by  Debtor  in the  ordinary  course  of  Debtor's  business
completed in accordance with the terms and provisions contained in the documents
available  to Lender with respect  thereto and are not  evidenced by a judgment,
Instrument  or Chattel  Paper,  (ii) the  amounts  shown on any  Borrowing  Base
Certificate,  summary or  schedules  of Account  or any aged  receivables  trial
balance  delivered  by Debtor to Lender  pursuant to the terms of this  Security
Agreement  or the Credit  Agreement  and on  Debtor's  books and records and all
invoices  and  statements  which may be  delivered  to the Lender  with  respect
thereto  are  actually  and  absolutely  owing to Debtor  and are not in any way
contingent,  (iii) to the best of  Debtor's  knowledge,  there are no  set-offs,
claims or disputes  existing or asserted with respect thereto and Debtor has not
made any agreement with any Account Debtor for any deduction  therefrom except a
discount or allowance  allowed by Debtor in the ordinary  course of its business
for prompt payment, (iv) to the best of Debtor's knowledge,  there are no facts,
events or occurrences that in any way impair the validity or enforcement thereof
or tend to reduce the amount payable  thereunder as shown on the respective aged
receivable  trial  balances,  Debtor's  books and records and all  invoices  and
statements delivered to Lender with respect thereto, (v) to the best of Debtor's
knowledge,  all Account  Debtors have the capacity to contract,  (vi) Debtor has
received no notice of  proceedings  or actions  which are  threatened or pending
against any Account Debtor which might result in any material  adverse change in
such Account Debtor's financial condition and (vii) Debtor has no knowledge that
any Account Debtor is unable generally to pay its debts as they become due.

             h. With respect to all Inventory and  Equipment,  (i) such property
is located at one of the locations  set forth on the Credit Party  Questionnaire
completed  by  Debtor  and  delivered  to  Lender,  (ii)  Debtor  has  good  and
merchantable title to such property and such property is not subject to any lien
or security  interest or document  whatsoever  except for the security  interest
granted  to Lender  hereunder  and any set forth on  Schedule  7.6 to the Credit
Agreement  and Permitted  Exceptions,  (iii) such property is not subject to any
licensing,  patent, royalty,  trademark, trade name or copyright agreements with
any third parties except as described on Schedule III, which agreements will not
materially  interfere with the sale or use of the Collateral by the Lender, (iv)
with respect to Inventory,  such property is of good and  merchantable  quality,
(v) with respect to Inventory,  such property is free from material defects, and
(vi) with respect to the Inventory, the completion of manufacture, sale or other
disposition  of such property by Lender  following an Event of Default shall not
require the consent of any Person and shall not  constitute  a breach or default
under any  contract  or  agreement  to which  Debtor is a party or to which such
property is subject.

             5. COVENANTS. Debtor covenants and agrees with Lender that from and
after the date of this Security Agreement and until the Termination Date:

             a. Further Assurances;  Pledge of Instruments. At any time and from
time to time,  upon the  written  request of Lender  and at the sole  expense of
Debtor,  Debtor  shall  promptly  and duly  execute and deliver any and all such
further  instruments  and documents  and take such further  action as Lender may
reasonably deem desirable to obtain the full benefits of this Security Agreement
and of the  rights  and  powers  herein  granted,  including  (i) using its best
efforts to secure all consents and approvals  necessary or  appropriate  for the
assignment  to or for the benefit of Lender of any  License or Contract  held by
Debtor or in which Debtor has any
                                       -5-
<PAGE>
rights not  heretofore  assigned,  (ii)  filing any  financing  or  continuation
statements  under  the UCC with  respect  to the liens  and  security  interests
granted  hereunder  or  under  any  other  Loan  Document,   (iii)  transferring
Collateral to Lender's  possession (if such Collateral consists of Chattel Paper
or  if a  security  interest  in  such  Collateral  can  be  perfected  only  by
possession,  or, if  requested  by Lender),  and (iv) using its best  efforts to
obtain  waivers of liens from  landlords  and  mortgagees.  Debtor  also  hereby
authorizes  Lender to file any such financing or continuation  statement without
the signature of Debtor to the extent permitted by applicable law. If any amount
payable  under or in  connection  with any of the  Collateral is or shall become
evidenced by any Instrument, such Instrument,  other than checks received in the
ordinary course of business (which shall be deposited to a Collection  Account),
shall be duly  endorsed  in a manner  satisfactory  to Lender  immediately  upon
Debtor's receipt thereof and delivered to Lender.

             b. Maintenance of Records.  Debtor shall keep and maintain,  at its
own cost and  expense,  satisfactory  and  complete  records of the  Collateral,
including  a record of any and all  payments  received  and any and all  credits
granted  with  respect  to the  Collateral  and  all  other  dealings  with  the
Collateral. Debtor shall mark its books and records pertaining to the Collateral
to evidence this Security  Agreement and the security  interests granted hereby.
All Chattel Paper shall be marked with the following  legend:  "This writing and
the obligations evidenced or secured hereby are subject to the security interest
of General Electric Capital Corporation".  For Lender's further security, Debtor
agrees that Lender shall have a special property right and security  interest in
all of Debtor's  books and records  pertaining to the  Collateral  and, upon the
occurrence  and during the  continuation  of any Event of Default,  Debtor shall
deliver  and  turn  over  any  such  books  and  records  to  Lender  or to  its
representatives at any time on demand of Lender;  provided, that the Lender will
provide the Debtor with copies of such books and records at Debtor's request and
expense.  Prior to the  occurrence  of an Event of Default  and upon  reasonable
notice from Lender,  Debtor shall permit any representative of Lender to inspect
such books and records and shall provide  photocopies  thereof to Lender as more
specifically set forth in Section 5(g) below.

             c.  Indemnification.  In any suit,  proceeding or action brought by
Lender relating to any Account,  Chattel Paper,  Contract,  General  Intangible,
Instrument or Document for any sum owing thereunder, or to enforce any provision
of any Account,  Chattel Paper,  Contract,  General Intangible,  Instrument,  or
Document, Debtor shall save, indemnify and keep Lender harmless from and against
all  expense,  loss or  damage  suffered  by  reason  of any  defense,  set-off,
counterclaim,  recoupment  or reduction of liability  whatsoever  of the obligor
thereunder  arising out of a breach by Debtor of any  obligation  thereunder  or
arising out of any other agreement,  indebtedness or liability at any time owing
to, or in favor of, such obligor or its  successors  from  Debtor,  and all such
obligations of Debtor shall be and remain enforceable against, and only against,
Debtor and shall not be enforceable  against  Lender;  provided,  however,  that
Debtor  shall not be  required  to  indemnify  Lender  with  respect to any such
expense,  loss or damage suffered by Lender as a result of its gross  negligence
or willful  misconduct  in collecting  any sum owing under any Account,  Chattel
Paper, Contract, General Intangible, Instrument or Document.

             d.  Compliance  with  Terms  of  Accounts,  etc.  In  all  material
respects,  Debtor shall  perform and comply with all  obligations  in respect of
Accounts, Chattel Paper, Contracts, Licenses, Instruments and Documents, and all
other agreements to which it is a party or by which it or any of its property is
bound.
                                       -6-

             e.  Limitation  on Liens on  Collateral.  Debtor  shall not create,
permit or suffer to exist, and shall defend the Collateral against and take such
other  action as is necessary to remove,  any Lien on the  Collateral  except as
otherwise  permitted  pursuant to Section 7.6 of the Credit Agreement and except
for  Permitted  Exceptions.  Debtor shall  further  defend the right,  title and
interest of Lender in and to any of Debtor's rights under the Accounts,  Chattel
Paper,  Contracts,  Documents,  General  Intangibles  and Instruments and to the
Inventory,  and in and to the Proceeds  thereof,  against the Liens,  claims and
demands of all Persons whomsoever.

             f. Limitations on  Modifications of Accounts.  Subject to the terms
of the Credit Agreement,  upon the occurrence and during the continuation of any
Event of Default,  Debtor shall not, without Lender's prior written consent, (i)
grant any  extension  of the time of  payment  of any of the  Accounts,  Chattel
Paper,  Instruments or amounts due under any Contract, (ii) compromise or settle
the same for less than the full amount  thereof,  (iii) release,  in whole or in
part,  any Person  liable for the payment  thereof,  or (iv) allow any credit or
discount  whatsoever  thereon other than trade discounts granted in the ordinary
course of business of Debtor.

             g. Right of Inspection. Upon reasonable notice to Debtor (unless an
Event of Default  has  occurred  and is  continuing,  in which case no notice is
necessary),  Lender shall at all times have full and free access  during  normal
business hours to all the books and records and  correspondence  of Debtor,  and
Lender or its  representatives may examine the same, take extracts therefrom and
make  photocopies  thereof,  and Debtor agrees to render to Lender,  at Debtor's
cost and  expense,  such  clerical  and other  assistance  as may be  reasonably
requested with regard thereto. Upon reasonable notice to Debtor (unless an Event
of  Default  has  occurred  and is  continuing,  in  which  case  no  notice  is
necessary),  Lender and its  representatives  shall also have the right to enter
into and upon any  premises  where  any of the  Collateral  is  located  for the
purpose  of  inspecting  the same,  observing  its use or  otherwise  protecting
Lender's interests in the Collateral.

             h.  Continuous  Perfection.  Debtor  shall  not  change  its  name,
identity or corporate  structure in any manner which might make any financing or
continuation  statement filed in connection herewith seriously misleading within
the  meaning  of  section  9-402(7)  of the  UCC or any  other  then  applicable
provision of the UCC unless  Debtor shall have given Lender at least thirty (30)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested by Lender to amend such financing statement or continuation  statement
so that it is not seriously misleading.

             6. LENDER'S APPOINTMENT AS ATTORNEY-IN-FACT.

             a. Debtor hereby  irrevocably  constitutes  and appoints Lender and
any officer or agent thereof,  with full power of substitution,  as its true and
lawful  attorney-in-fact  with full irrevocable power and authority in the place
and stead of Debtor  and in the name of Debtor or in its own name,  from time to
time in Lender's  reasonable  discretion,  for the  purpose of carrying  out the
terms of this Security Agreement,  to take any and all appropriate action and to
execute and deliver any and all documents and  instruments  which may reasonably
be necessary or desirable to accomplish the purposes of this Security  Agreement
and, without  limiting the generality of the foregoing,  hereby grants to Lender
the power and  right,  on behalf of Debtor,  upon  notice to or assent by Debtor
(which  notice  may be  simultaneous  with such  action),  at any time after the
occurrence  and  during  the  continuation  of an  Event of  Default,  to do the
following:

                    (i) in the name of  Debtor,  in its own  name or  otherwise,
             take  possession  of,  endorse and  receive  payment of any checks,
             drafts, notes, acceptances, or other Instruments for the payment of
             monies due under any Collateral;

                    (ii) continue any insurance  existing  pursuant to the terms
             of the  Loan  Documents,  and pay all or any  part of the  premiums
             therefor and the costs thereof; and

                    (iii)  receive  payment of any and all monies,  claims,  and
             other amounts due or to become due at any time arising out of or in
             respect of any Collateral.

             b. Debtor hereby  irrevocably  constitutes  and appoints Lender and
any officer or agent thereof,  with full power of substitution,  as its true and
lawful  attorney-in-fact  with full irrevocable power and authority in the place
and stead of Debtor  and in the name of Debtor or in its own name,  from time to
time in Lender's  reasonable  discretion,  for the  purpose of carrying  out the
terms of this Security Agreement,  to take any and all appropriate action and to
execute and deliver any and all documents and  instruments  which may reasonably
be necessary or desirable to accomplish the purposes of this Security  Agreement
and, without  limiting the generality of the foregoing,  hereby grants to Lender
the power and right,  on behalf of Debtor,  upon notice to (which  notice may be
simultaneous  with such  action)  but  without  the assent of  Debtor,  upon the
occurrence  and  during  the  continuation  of an  Event of  Default,  to do the
following:

                    (i) ask, demand, collect,  receive and give acquittances and
             receipts  for any and all  money  due or to  become  due  under any
             Collateral;

                    (ii) pay or discharge taxes,  liens,  security interest,  or
             other  encumbrances  levied or placed on or threatened  against the
             Collateral;

                    (iii)  obtain any  insurance  called for by the terms of the
             Loan Documents and pay all or any part of the premiums therefor and
             costs thereof;

                    (iv)  direct any party  liable for any  payment  under or in
             respect  of any of the  Collateral  to make  payment of any and all
             monies due or to become due thereunder, 
                                      -8-
<PAGE>
             directly to Lender or as Lender shall direct;

                    (v) sign and endorse any invoices, freight or express bills,
             bills of lading,  storage or  warehouse  receipts,  drafts  against
             debtors, assignments, verifications, and notices in connection with
             accounts  and  other  documents  constituting  or  related  to  the
             Collateral;

                    (vi)  settle,  compromise  or adjust  any suit,  action,  or
             proceeding described above and, in connection therewith,  give such
             discharges or releases as Lender may deem appropriate;

                    (vii) file any claim or take or commence any other action or
             proceeding  in any court of law or equity or  otherwise  reasonably
             deemed  appropriate by Lender for the purpose of collecting any and
             all such monies due under any Collateral whenever payable;

                    (viii)   commence  and  prosecute  any  suits,   actions  or
             proceedings of law or equity in any court of competent jurisdiction
             to collect the  Collateral  or any part  thereof and to enforce any
             other right in respect of any Collateral;

                    (ix) defend any suit,  action or proceeding  brought against
             Debtor  with  respect to any  Collateral  if Debtor does not defend
             such suit,  action or proceeding or if Lender  reasonably  believes
             that  Debtor is not  pursuing  such  defense in a manner  that will
             maximize the recovery with respect to such Collateral;

                    (x) license  or, to the extent  permitted  by an  applicable
             license,  sublicense  whether general,  specific or otherwise,  and
             whether  on an  exclusive  or  non-exclusive  basis,  any Patent or
             Trademark throughout the world for such or terms on such conditions
             and in such manner as Lender shall,  in its reasonable  discretion,
             determine; and

                    (xi) sell, transfer, pledge, make any agreement with respect
             to,  or  otherwise  deal  with any of the  Collateral  as fully and
             completely as though Lender were the absolute owner thereof for all
             purposes,  and to do, at Lender's option and Debtor's  expense,  at
             any time,  or from time to time,  all acts and things  which Lender
             reasonably  deems necessary to perfect,  preserve,  or realize upon
             the  Collateral  and  Lender's  Lien thereon in order to effect the
             intent of this Security Agreement,  all as fully and effectively as
             Debtor might do.

             c. Debtor hereby ratifies, to the extent permitted by law, all that
said attorneys shall lawfully do or cause to be done by virtue hereof. The power
of  attorney  granted  pursuant  to this  Section 6 is a power  coupled  with an
interest and shall be irrevocable until the Termination Date.
                                       -9-
<PAGE>
             d. The powers  conferred on Lender  hereunder are solely to protect
Lender's  interests in the  Collateral  and shall not impose any duty upon it to
exercise any such powers.  Lender shall be accountable  only for amounts that it
actually  receives as a result of the exercise of such powers.  None of Lender's
officers,  directors,  employees, agents or representatives shall be responsible
to Debtor for any failure to act,  and in taking  affirmative  action,  shall be
liable only to the extent that such Persons are finally determined by a court of
competent jurisdiction to be guilty of gross negligence or willful misconduct.

             e. Following the occurrence and during the continuation of an Event
of Default, Debtor also authorizes Lender, at any time and from time to time, to
(i)  communicate  in its own name with any party to any Contract  with regard to
the  assignment  of the  right,  title and  interest  of Debtor in and under the
Contracts and other  matters  relating  thereto and (ii) execute,  in connection
with the sale provided for in Section 8 hereof, any endorsements, assignments or
other instruments of conveyance or transfer with respect to the Collateral.

             7. PERFORMANCE BY LENDER OF DEBTOR'S SECURED OBLIGATIONS. If Debtor
fails to perform or comply with any of its agreements contained herein or in any
of the other Loan  Documents,  and Lender,  as provided for by the terms of this
Security  Agreement or any of the other Loan Documents,  shall itself perform or
comply,  or otherwise cause  performance of or compliance,  with such agreement,
the  reasonable  expenses,  including  attorneys'  fees,  of Lender  incurred in
connection with such  performance or compliance,  together with interest thereon
at the rate then in effect in respect of the  Revolving  Credit  Loan,  shall be
payable by Debtor to Lender on demand and shall constitute  Secured  Obligations
secured hereby.

             8. REMEDIES; RIGHTS UPON DEFAULT.

             a. If any Event of Default  shall occur and be  continuing,  Lender
may exercise in addition to all other  rights and  remedies  granted to it under
this Security  Agreement,  the Credit  Agreement,  the other Loan  Documents and
under any other instrument or agreement  securing,  evidencing,  guaranteeing or
otherwise relating to the Secured  Obligations,  all rights and remedies that it
has as a secured  party under the UCC.  Without  limiting the  generality of the
foregoing, Debtor expressly agrees that in any such event Lender, without demand
of performance or other demand,  advertisement or notice of any kind (except the
notice  specified  below of time and  place of public  or  private  sale and any
notice  expressly  required by the Guaranty  Agreement) to or upon Debtor or any
other  Person  (all and each of which  demands,  advertisements  and notices are
hereby  expressly  waived to the maximum  extent  permitted by the UCC and other
applicable  law),  may  forthwith  enter upon the  premises of Debtor  where any
Collateral is located through self-help, without judicial process, without first
obtaining a final judgment or giving Debtor notice and opportunity for a hearing
on Lender's  claim or action,  and without  paying rent to Debtor,  and collect,
receive, assemble, process,  appropriate and realize upon the Collateral, or any
part thereof,  and may forthwith sell, lease,  assign, give an option or options
to purchase,  or sell or otherwise  dispose of and deliver said  Collateral  (or
contract to do so),  or any part  thereof,  in one or more  parcels at public or
private sale or sales,  at any exchange at such prices as it may deem best,  for
cash or on credit or for future delivery without  assumption of any credit risk.
Lender  shall have the right upon any such public sale or sales,  
                                      -10-
<PAGE>
and, to the extent  permitted by law,  upon any such  private sale or sales,  to
purchase for the benefit of Lender the whole or any part of said  Collateral  so
sold,  free of any right or equity of  redemption,  which  equity of  redemption
Debtor hereby  releases.  Such sales may be adjourned and continued from time to
time with or without  notice.  Lender shall have the right to conduct such sales
on  Debtor's  premises  or  elsewhere  and shall have the right to use  Debtor's
premises  without  charge  for such  time or times as  Lender  reasonably  deems
necessary or advisable.

             Debtor  further  agrees,  at  Lender's  request,  to  assemble  the
Collateral  and make it  available  to  Lender  at  places  which  Lender  shall
reasonably  select,  whether at Debtor's premises or elsewhere.  Until Lender is
able to effect a sale, lease, or other  disposition of Collateral,  Lender shall
have the right to use, operate or administer  Collateral on behalf of Lender, or
any part thereof,  to the extent that it reasonably  deems  appropriate  for the
purpose  of  preserving  Collateral  or its  value  or  for  any  other  purpose
reasonably  deemed  appropriate  by Lender.  Lender shall have no  obligation to
Debtor to  maintain or preserve  the rights of Debtor as against  third  parties
with respect to  Collateral  while  Collateral  is in the  possession of Lender.
Lender may, if it so elects and, to the extent not prohibited by applicable law,
seek the  appointment  of a receiver or keeper to take  possession of Collateral
and to enforce any of Lender's remedies with respect to such appointment without
prior  notice  or  hearing.  Lender  shall  apply the net  proceeds  of any such
collection, recovery, receipt, appropriation, realization or sale as provided in
Section 8(d) hereof, Debtor remaining liable for any deficiency remaining unpaid
after such  application,  and only after so paying  over such net  proceeds  and
after the payment by Lender of any other  amount  required by any  provision  of
law,  including  section  9-504(1)(c)  of the UCC (but  only  after  Lender  has
received  what  Lender  considers  reasonable  proof  of a  subordinate  party's
security  interest),  need Lender account for the surplus, if any, to Debtor. To
the maximum  extent  permitted  by  applicable  law,  Debtor  waives all claims,
damages,  and demands against Lender arising out of the repossession,  retention
or sale of the  Collateral  except  to the  extent  that a  court  of  competent
jurisdiction  issues a final  determination  that such  claims or damages  arise
solely out of the gross negligence or willful  misconduct of such party.  Debtor
agrees that ten (10) days'  prior  notice by Lender of the time and place of any
public  sale or of the  time  after  which a  private  sale  may  take  place is
reasonable  notification  of such  matters.  Debtor shall remain  liable for any
deficiency  if the proceeds of any sale or  disposition  of the  Collateral  are
insufficient  to pay all amounts to which Lender is entitled,  Debtor also being
liable for any  reasonable  attorneys'  fees  incurred by Lender to collect such
deficiency.

             b.  Debtor  agrees to pay any and all  reasonable  costs of Lender,
including,   without  limitation,   reasonable   attorneys'  fees,  incurred  in
connection with the enforcement of any of its rights and remedies hereunder.

             c. Except as otherwise  specifically provided herein or in the Loan
Documents,  Debtor hereby waives presentment,  demand, protest or any notice (to
the maximum extent  permitted by applicable  law) of any kind in connection with
the Loan Documents, the Security Agreement or any Collateral.

             d. The Proceeds of any sale,  disposition or other realization upon
all or any part of the  Collateral  shall be distributed by Lender upon receipt,
in the following order of priorities:
                                      -11-
<PAGE>
                    first, to Lender in an amount  sufficient to pay in full the
             reasonable  expenses  of  Lender  in  connection  with  such  sale,
             disposition   or  other   realization,   including   all  expenses,
             liabilities  and advances  incurred or made by Lender in connection
             therewith, including reasonable attorney's fees;

                    second,  to Lender  in an  amount  equal to the then due and
             unpaid accrued interest,  fees and prepayment premiums,  if any, on
             the Secured Obligations;

                    third,  to  Lender in an  amount  equal to any other  unpaid
             Secured Obligations or amounts owed, if any, in connection with the
             Secured Obligations; and

                    finally,  upon  payment  in  full  of  all  of  the  Secured
             Obligations,  to Debtor or its representatives or to whomsoever may
             be  lawfully  entitled  to  receive  the  same,  or as a  court  of
             competent jurisdiction may direct.

             9. GRANT OF LICENSE TO USE PATENT AND TRADEMARK COLLATERAL. For the
purpose of  enabling  Lender to exercise  rights and  remedies  under  Section 8
hereof  (including,  without limiting the terms of Section 8 hereof, in order to
take possession of, hold, preserve,  process, assemble, prepare for sale, market
for sale, sell or otherwise  dispose of Collateral) at such time as Lender shall
be lawfully entitled to exercise such rights and remedies,  Debtor hereby grants
to Lender an irrevocable,  non-exclusive license (exercisable without payment of
royalty or other compensation to Debtor) to use, transfer, license or sublicense
any  Patent,  Trademark,  trade  secret,  or  copyright  now owned or  hereafter
acquired by Debtor, and wherever the same may be located,  and including in such
license reasonable access to all media in which any of the licensed items may be
recorded or stored and to all  computer  and  automatic  machinery  software and
programs  used for the  compilation  or  printout  thereof;  provided  that such
license  shall be  exercisable  only at such time as the  Lender  shall have the
right to exercise its rights and remedies under Section 8 hereof.

             10.  LIMITATION ON LENDER'S DUTY IN RESPECT OF  COLLATERAL.  Lender
shall use  reasonable  care with respect to the  Collateral in its possession or
under its control.  Lender shall not have any other duty as to any Collateral in
its  possession  or  control  or in the  possession  or  control of any agent or
nominee of Lender,  or any income  thereon or as to the  preservation  of rights
against  prior  parties or any other  rights  pertaining  thereto.  Lender shall
account for any monies  received by Lender in respect of any  foreclosure  on or
disposition of the Collateral.

             11.  REINSTATEMENT.  This Agreement  shall remain in full force and
effect and continue to be  effective  should any petition be filed by or against
Debtor for liquidation or reorganization, should Debtor become insolvent or make
an  assignment  for the benefit of  creditors or should a receiver or trustee be
appointed for all or any significant part of Debtor's assets, and shall continue
to be effective or be reinstated, as the case may be, if at any time payment and
performance of the Secured  Obligations,  or any part thereof,  is,  pursuant to
applicable law, rescinded or reduced in amount, or must otherwise be restored or
returned  by any  obligee of the  Secured  Obligations,  whether as a  "voidable
preference,"  "fraudulent  conveyance," or otherwise, all as though such payment
or performance had not been made. In
                                      -12-
<PAGE>
the event that any payment, or any part thereof, is rescinded, reduced, restored
or returned, the Secured Obligations shall be reinstated and deemed reduced only
by such amount paid and not so rescinded, reduced, restored or returned.

             12. NOTICES.  Except as otherwise  provided herein,  whenever it is
provided herein that any notice, demand, request, consent, approval, declaration
or other  communication  shall or may be given to or served  upon  either of the
parties by the other party, or whenever either of the parties desires to give or
serve upon the other  party any  communication  with  respect  to this  Security
Agreement, each such notice, demand, request, consent, approval,  declaration or
other  communication  shall be in writing and shall be given in the manner,  and
deemed received, as provided for in Section 11 of the Guaranty Agreement.

             13.  SEVERABILITY;   COMPLETE  AGREEMENT.  Any  provision  of  this
Security  Agreement  which is prohibited or  unenforceable  in any  jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such prohibition
or unenforceability  without  invalidating the remaining  provisions hereof, and
any  such  prohibition  or   unenforceability  in  any  jurisdiction  shall  not
invalidate or render  unenforceable  such  provision in any other  jurisdiction.
This Security  Agreement is to be read,  construed and applied together with the
Credit Agreement and the other Loan Documents,  which, taken together, set forth
the complete  understanding  and  agreement of Lender and Debtor with respect to
the matters  referred to herein and therein and supersede all prior  agreements,
understandings or inducements whether express or implied, or oral or written.

             14. NO WAIVER;  CUMULATIVE  REMEDIES.  Lender shall not by any act,
delay,  omission  or  otherwise  be deemed to have  waived  any of its rights or
remedies  hereunder,  and no waiver shall be valid unless in writing,  signed by
Lender and then only to the extent  therein set forth. A waiver by Lender of any
right or remedy hereunder on any one occasion shall not be construed as a bar to
any  right or  remedy  which  Lender  would  otherwise  have  had on any  future
occasion.  No failure to  exercise  nor any delay in  exercising  on the part of
Lender,  any right,  power or  privilege  hereunder,  shall  operate as a waiver
thereof,  nor shall any  single  or  partial  exercise  of any  right,  power or
privilege  hereunder  preclude  any  other or  future  exercise  thereof  or the
exercise  of any other  right,  power or  privilege.  The  rights  and  remedies
hereunder  provided are cumulative and may be exercised  singly or concurrently,
and are not  exclusive of any rights and remedies  provided by law.  None of the
terms or provisions of this Security Agreement may be waived, altered,  modified
or amended  except by an  instrument  in  writing,  duly  executed by Lender and
Debtor.

             15.  LIMITATION BY LAW; TIME OF ESSENCE.  All rights,  remedies and
powers  provided in this Security  Agreement may be exercised only to the extent
that the exercise thereof does not violate any applicable  provision of law, and
all the provisions of this Security  Agreement are intended to be subject to all
applicable mandatory provisions of law that may be controlling and to be limited
to the extent  necessary so that they shall not render this  Security  Agreement
invalid,  unenforceable,  in whole or in part,  or not  entitled to be recorded,
registered,  or filed under the provisions of any applicable law. Time is of the
essence of this Security Agreement.

             16.  TERMINATION  OF  THIS  SECURITY  AGREEMENT.  Subject  to  
                                      -13-
<PAGE>
Section 11 hereof,  this Security Agreement shall terminate upon the Termination
Date and all of Lender's  rights,  titles and interests in and to the Collateral
hereunder shall be automatically terminated and released on such date.

             17.  SUCCESSORS  AND  ASSIGNS.  This  Security  Agreement  and  all
obligations of Debtor hereunder shall be binding upon the successors and assigns
of Debtor, and shall, together with the rights and remedies of Lender hereunder,
inure to the benefit of Lender, all future holders of any instrument  evidencing
any of the Secured  Obligations and their respective  successors and assigns. No
sales  of  participations,   other  sales,   assignments,   transfers  or  other
dispositions  of any agreement  governing or instrument  evidencing  the Secured
Obligations  or any  portion  thereof or  interest  therein  shall in any manner
affect the security interest granted to Lender hereunder. Debtor may not assign,
sell or otherwise transfer an interest in this Security Agreement.

             18.  EXECUTION IN  COUNTERPARTS.  This  Security  Agreement  may be
executed in any number of  counterparts,  each of which shall  collectively  and
separately constitute one agreement.

             19.  GOVERNING LAW;  CONSENT TO JURISDICTION  AND VENUE.  EXCEPT AS
OTHERWISE  EXPRESSLY  PROVIDED IN ANY OF THE LOAN  DOCUMENTS,  IN ALL  RESPECTS,
INCLUDING ALL MATTERS OF CONSTRUCTION,  VALIDITY AND PERFORMANCE,  THIS SECURITY
AGREEMENT AND THE SECURED  OBLIGATIONS  ARISING  HEREUNDER SHALL BE GOVERNED BY,
AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK
APPLICABLE  TO CONTRACTS  MADE AND PERFORMED IN SUCH STATE,  AND ANY  APPLICABLE
LAWS OF THE UNITED STATES OF AMERICA. DEBTOR HEREBY CONSENTS AND AGREES THAT THE
STATE OR FEDERAL  COURTS  LOCATED IN THE BOROUGH OF MANHATTAN,  NEW YORK,  SHALL
HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN
DEBTOR AND LENDER PERTAINING TO THIS SECURITY AGREEMENT OR TO ANY MATTER ARISING
OUT OF OR RELATING TO THIS SECURITY  AGREEMENT,  THE CREDIT  AGREEMENT OR ANY OF
THE OTHER LOAN DOCUMENTS,  PROVIDED, THAT LENDER AND DEBTOR ACKNOWLEDGE THAT ANY
APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF THE
BOROUGH OF  MANHATTAN,  NEW YORK AND,  PROVIDED,  FURTHER,  THAT NOTHING IN THIS
AGREEMENT  SHALL BE DEEMED OR OPERATE TO PRECLUDE  LENDER FROM  BRINGING SUIT OR
TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO REALIZE ON THE COLLATERAL
OR ANY OTHER SECURITY FOR THE SECURED  OBLIGATIONS,  OR TO ENFORCE A JUDGMENT OR
OTHER COURT ORDER IN FAVOR OF LENDER AND,  PROVIDED,  FURTHER,  THAT  NOTHING IN
THIS  AGREEMENT  SHALL BE  DEEMED TO  PRECLUDE  THE  DEBTOR  FROM  PURSUING  ANY
COMPULSORY  COUNTERCLAIM  IN ANY  PROCEEDING  BROUGHT  BY THE LENDER IN ANY SUCH
OTHER  JURISDICTION.  DEBTOR  EXPRESSLY  SUBMITS AND CONSENTS IN ADVANCE TO SUCH
JURISDICTION  IN ANY  ACTION OR SUIT  COMMENCED  IN ANY SUCH  COURT,  AND DEBTOR
HEREBY  WAIVES ANY  OBJECTION  WHICH DEBTOR MAY HAVE BASED UPON LACK OF PERSONAL
JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY
                                      -14-
<PAGE>
CONSENTS  TO THE  GRANTING  OF SUCH  LEGAL  OR  EQUITABLE  RELIEF  AS IS  DEEMED
APPROPRIATE BY SUCH COURT. DEBTOR HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS,
COMPLAINT  AND OTHER  PROCESS  ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT
SERVICE OF SUCH SUMMONS,  COMPLAINTS AND OTHER PROCESS MAY BE MADE BY REGISTERED
OR  CERTIFIED  MAIL  ADDRESSED TO DEBTOR IN  ACCORDANCE  WITH SECTION 12 OF THIS
SECURITY  AGREEMENT AND THAT SERVICE SO MADE SHALL BE DEEMED  COMPLETED UPON THE
EARLIER OF DEBTOR'S  ACTUAL  RECEIPT  THEREOF OR FIVE DAYS AFTER  DEPOSIT IN THE
U.S. MAILS, PROPER POSTAGE PREPAID.

             21.  MUTUAL  WAIVER OF JURY  TRIAL.  BECAUSE  DISPUTES  ARISING  IN
CONNECTION WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY
RESOLVED BY AN  EXPERIENCED  AND EXPERT  PERSON AND THE PARTIES WISH  APPLICABLE
STATE AND FEDERAL LAWS TO APPLY  (RATHER THAN  ARBITRATION  RULES),  THE PARTIES
DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS.
THEREFORE,  TO ACHIEVE THE BEST  COMBINATION  OF THE  BENEFITS  OF THE  JUDICIAL
SYSTEM AND OF  ARBITRATION,  THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY
IN ANY ACTION,  SUIT,  OR  PROCEEDING  BROUGHT TO RESOLVE ANY  DISPUTE,  WHETHER
SOUNDING IN CONTRACT,  TORT, OR OTHERWISE,  BETWEEN THE PARTIES  ARISING OUT OF,
CONNECTED  WITH,  RELATED  TO, OR  INCIDENTAL  TO THE  RELATIONSHIP  ESTABLISHED
BETWEEN THEM IN CONNECTION WITH, THIS SECURITY AGREEMENT,  THE CREDIT AGREEMENT,
OR ANY OF THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS RELATED THERETO.
                                      -15-

             IN WITNESS WHEREOF, Debtor has caused this Security Agreement to be
executed and delivered by its duly  authorized  officer as of the date first set
forth above.

                              W I T N E S S E T H:

             WHEREAS,  pursuant  to that  certain  Amended and  Restated  Credit
Agreement  dated  as of April  11,  1994,  by and  among  Vodavi  Communications
Systems, Inc., an Arizona corporation formerly known as V Technology Acquisition

modified,  the "Credit  Agreement"),  Lender has agreed,  among other things, to
make a certain  Revolving  Credit  Loan (as  defined  in the  Credit  Agreement)
available to Borrower; and

             WHEREAS,  pursuant to that certain Guaranty Agreement,  dated as of
June 11, 1997, executed by Debtor and Enhanced Systems,  Inc. in favor of Lender
(the "Guaranty Agreement"), Debtor has guaranteed the payment and performance by
Borrower of all  obligations  of  Borrower  arising  under the Credit  Agreement
(including without limitation payment of the Revolving Credit Loan); and

             WHEREAS,  Lender is willing to make the  Revolving  Credit Loan and
any other extension of credit provided for in the Credit Agreement  available to
Borrower,  but only upon the  condition,  among  others,  that Debtor shall have
executed and delivered this Security Agreement in favor of Lender; and

             NOW,  THEREFORE,  in consideration of the premises and the Lender's
commitment to make the Revolving Credit Loan available to Borrower,  the parties
hereto agree as follows:

             1. DEFINED TERMS.  Unless  otherwise  defined  herein,  capitalized
terms defined in the Credit Agreement are used herein as therein defined.

             2. GRANT OF SECURITY INTEREST.

             a. To secure the  prompt  and  complete  payment,  performance  and
observance of all of the  obligations,  indebtedness  and  liabilities of Debtor
under the Guaranty Agreement (collectively,  the "Secured Obligations"),  and to
induce Lender to enter into the Credit Agreement, to issue the Commitment and to
make the Revolving  Credit Loan and any other  extensions of credit provided for
therein  available to Borrower in accordance with the respective  terms thereof,
Debtor  hereby  grants to Lender a security  interest in all of Debtor's  right,
title and interest in, to and under the following  whether now owned by or owing
to, or hereafter acquired by or arising in favor of Debtor  (including,  without
limitation, under any trade names, styles or
<PAGE>
divisions  thereof),  and  regardless  of  where  located  (all of  which  being
hereinafter collectively referred to as the "Collateral"):

                    (i) all Accounts;

                    (ii) all Chattel Paper;

                    (iii) all Contracts;

                    (iv) all Documents;

                    (v) all Equipment;
  
                    (vi) all General Intangibles;

                    (vii) all Instruments;

                    (viii) all Inventory;

                    (ix) all other money, cash or cash equivalents of Debtor;

                    (x) all  books and  records  (including  without  limitation
             credit files,  customer lists,  computer files,  computer programs,
             computer   printouts,   or  other  computer   material)  of  Debtor
             identifying,  evidencing  or  otherwise  pertaining  to  any of the
             Collateral described above; and

                    (xi) all Proceeds of any of the Collateral described above.

             b.  In  addition,  to  secure  the  prompt  and  complete  payment,
performance  and  observance of the Secured  Obligations  and in order to induce
Lender as aforesaid,  Debtor hereby grants to Lender, a security interest in all
property of Debtor held by Lender, including,  without limitation,  all property
of every  description,  now or hereafter in the  possession  or custody of or in
transit to Lender for any purpose, including safekeeping,  collection or pledge,
for the account of Debtor, or as to which Debtor may have any right or power.

             3. LENDER'S RIGHTS; LIMITATIONS ON LENDER'S SECURED
                OBLIGATIONS.

             a. It is expressly  agreed by Debtor that,  anything  herein to the
contrary notwithstanding, Debtor shall remain liable under each of its Contracts
and  each  of its  Licenses  to  observe  and  perform  all the  conditions  and
obligations  to be observed and performed by it thereunder and Lender shall have
no obligation or liability under any Contract or License by reason of or arising
out of this  Security  Agreement or the granting  herein of a security  interest
therein or the  receipt by Lender of any  payment  relating  to any  Contract or
License pursuant hereto, nor shall Lender be required or obligated in any manner
to perform or fulfill any of the  obligations of Debtor under or pursuant to any
Contract or License,  or to make any  payment,  or to make any inquiry as to the
nature or the sufficiency of any payment received by it or the
                                       -2-
<PAGE>
sufficiency of any performance by any party under any Contract or License, or to
present or file any  claims,  or to take any  action to  collect or enforce  any
performance  or the payment of any amounts which may have been assigned to it or
to which it may be entitled at any time or times.

             b.  Lender  may at any time  after the  occurrence  and  during the
continuation  of an Event of Default and upon 24 hours  prior  notice to Debtor,
notify Account  Debtors,  parties to the  Contracts,  and obligors in respect of
Instruments,  that the Accounts  and the right,  title and interest of Debtor in
and under such Contracts and  Instruments  have been assigned to Lender and that
payments  shall be made  directly  to  Lender,  and upon the  request of Lender,
Debtor shall so notify Account  Debtors,  parties to Contracts,  and obligors in
respect of  Instruments.  Lender may at any time after the occurrence and during
the continuation of an Event of Default and upon notice to the Debtor (which may
be  simultaneous  with notice to Obligors on chattel  paper) notify  obligors in
respect of Chattel  Paper that the right,  title and  interest  of Debtor in and
under such Chattel Paper have been assigned to Lender and that payments shall be
made directly to Lender.

             c.  Lender  at  any  time  after  the  occurrence  and  during  the
continuation  of an  Event  of  Default  shall  have  the  right  to  make  test
verifications  of the Accounts and  verifications  and  appraisals  of the other
Collateral  in any manner and through any medium  that it  reasonably  considers
advisable,  and Debtor agrees to furnish all such  assistance and information as
Lender may reasonably  require in connection  therewith.  Lender may at any time
after the  occurrence  and during the  continuation  of an Event of Default,  in
Lender's own name or in the name of Debtor,  communicate  with Account  Debtors,
parties to Contracts, obligors in respect of Instruments and obligors in respect
of Chattel  Paper to verify with such  Persons,  to Lender's  satisfaction,  the
existence,  amount and terms of any such  Accounts,  Contracts,  Instruments  or
Chattel  Paper.  Upon the occurrence  and  continuation  of an Event of Default,
Debtor,  at its own expense,  shall cause the certified  public  accountant then
engaged by Debtor, to prepare and deliver to Lender at any time and from time to
time promptly upon Lender's request the following reports:  (i) a reconciliation
of all Accounts, (ii) an aging of all Accounts, (iii) trial balances, and (iv) a
test verification of such Accounts as Lender reasonably may request.

             4.  REPRESENTATIONS  AND WARRANTIES.  Debtor hereby  represents and
warrants that:

             a. Except for the  security  interest  granted to Lender under this
Security  Agreement,  and the  Liens  set forth on  Schedule  7.6 to the  Credit
Agreement and Permitted Exceptions, Debtor is the sole owner of each item of the
Collateral in which it purports to grant a security interest  hereunder,  having
good and marketable title thereto free and clear of any and all liens,  security
interests or other encumbrances.

             b. No effective security agreement, financing statement, equivalent
security or lien instrument or continuation  statement  covering all or any part
of the Collateral is on file or of record in any public office, except as may be
set forth on Schedule 7.6 to the Credit Agreement or such as may have been filed
by Debtor in favor of Lender pursuant to this Security Agreement.

             c. As a result of the filing of appropriate financing statements in
the filing  offices  listed on Schedule I hereto,  this  Security  Agreement  is
effective to create a valid and
                                       -3-
<PAGE>
continuing  lien on and  perfected  security  interest in favor of Lender in the
Collateral with respect to which a security  interest may be perfected by filing
pursuant  to the UCC,  which lien and  security  interest  is prior to all other
Liens,  except only for Liens  specifically  designated on Schedule 7.6 as being
prior to Lender's Liens and Permitted  Prior  Exceptions,  and is enforceable as
such as against  creditors of and purchasers  from Debtor (other than purchasers
of  Inventory  in the  ordinary  course of  business).  All action  necessary or
desirable  to protect and  perfect  such  security  interest in each item of the
Collateral has been duly taken.

             d. Schedule II hereto lists all  Instruments of Debtor.  All action
necessary or desirable to protect and perfect the security interest of Lender in
each item set forth on Schedule  II,  including  the  delivery of all  originals
thereof to Lender,  has been duly taken. The security  interest of Lender in the
Collateral listed on Schedule II hereto is prior to all other Liens except those
Liens  specifically  designated on Schedule 7.6 as being prior to Lender's Liens
and Permitted Prior  Exceptions and is enforceable as such against  creditors of
and purchasers from Debtor.

             e. Debtor's chief  executive  office,  principal place of business,
corporate offices, all warehouses and premises within which Collateral is stored
and located and the locations of all of its records  concerning  the  Collateral
are set  forth  on the  Credit  Party  Questionnaire  completed  by  Debtor  and
delivered  to Lender,  and Debtor shall not change its chief  executive  office,
principal  place of business,  corporate  offices or  Collateral  locations,  or
remove such records unless it shall have notified the Lender in writing at least
30 days prior to such  change  and shall  have  taken such  action as the Lender
deems  reasonably  necessary  to cause the Lien of Lender in the  Collateral  to
continue to be perfected.

             f.  During  the  five (5) year  period  preceding  the date of this
Agreement,  Debtor has not been known as or used and Debtor  presently  does not
use any corporate  name other than its name as set forth in its signature  below
and  those  other  corporate,  fictitious  or trade  names (if any) of Debtor as
disclosed on the Credit Party Questionnaire completed by Debtor and delivered to
Lender.  If such  schedule  sets forth any  fictitious or trade names for Debtor
(collectively,  the "Trade Names"), Debtor represents and warrants to and agrees
with Lender that: (i) any  Collateral  arising out of any sales under any of the
Trade Names is the  property  of and  belongs to Debtor,  (ii) each of the Trade
Names  is a trade  name or  trade  style  (and not an  independent  or  separate
corporation or other legal entity) by which Debtor may identify or market itself
or under which  Debtor may sell certain  products,  render  certain  services or
otherwise conduct some or all of its business, (iii) any Collateral which arises
from any sales made,  services rendered or other business conducted under any of
the Trade Names shall be owned solely by Debtor, and (iv) Debtor hereby appoints
Lender to be its attorney-in-fact to file such certificates  disclosing Debtor's
use of the Trade  Names and to take such  other  actions on  Debtor's  behalf as
Lender  reasonably  considers   appropriate  to  comply  with  any  statutes  or
regulations relating to the use of fictitious or assumed business names.
                                       -4-
<PAGE>
             g. (i) The  Accounts  represent  bona fide  sales of  Inventory  or
services  rendered  by  Debtor  in the  ordinary  course  of  Debtor's  business
completed in accordance with the terms and provisions contained in the documents
available  to Lender with respect  thereto and are not  evidenced by a judgment,
Instrument  or Chattel  Paper,  (ii) the  amounts  shown on any  Borrowing  Base
Certificate,  summary or  schedules  of Account  or any aged  receivables  trial
balance  delivered  by Debtor to Lender  pursuant to the terms of this  Security
Agreement  or the Credit  Agreement  and on  Debtor's  books and records and all
invoices  and  statements  which may be  delivered  to the Lender  with  respect
thereto  are  actually  and  absolutely  owing to Debtor  and are not in any way
contingent,  (iii) to the best of  Debtor's  knowledge,  there are no  set-offs,
claims or disputes  existing or asserted with respect thereto and Debtor has not
made any agreement with any Account Debtor for any deduction  therefrom except a
discount or allowance  allowed by Debtor in the ordinary  course of its business
for prompt payment, (iv) to the best of Debtor's knowledge,  there are no facts,
events or occurrences that in any way impair the validity or enforcement thereof
or tend to reduce the amount payable  thereunder as shown on the respective aged
receivable  trial  balances,  Debtor's  books and records and all  invoices  and
statements delivered to Lender with respect thereto, (v) to the best of Debtor's
knowledge,  all Account  Debtors have the capacity to contract,  (vi) Debtor has
received no notice of  proceedings  or actions  which are  threatened or pending
against any Account Debtor which might result in any material  adverse change in
such Account Debtor's financial condition and (vii) Debtor has no knowledge that
any Account Debtor is unable generally to pay its debts as they become due.

             h. With respect to all Inventory and  Equipment,  (i) such property
is located at one of the locations  set forth on the Credit Party  Questionnaire
completed  by  Debtor  and  delivered  to  Lender,  (ii)  Debtor  has  good  and
merchantable title to such property and such property is not subject to any lien
or security  interest or document  whatsoever  except for the security  interest
granted  to Lender  hereunder  and any set forth on  Schedule  7.6 to the Credit
Agreement  and Permitted  Exceptions,  (iii) such property is not subject to any
licensing,  patent, royalty,  trademark, trade name or copyright agreements with
any third parties except as described on Schedule III, which agreements will not
materially  interfere with the sale or use of the Collateral by the Lender, (iv)
with respect to Inventory,  such property is of good and  merchantable  quality,
(v) with respect to Inventory,  such property is free from material defects, and
(vi) with respect to the Inventory, the completion of manufacture, sale or other
disposition  of such property by Lender  following an Event of Default shall not
require the consent of any Person and shall not  constitute  a breach or default
under any  contract  or  agreement  to which  Debtor is a party or to which such
property is subject.

             5. COVENANTS. Debtor covenants and agrees with Lender that from and
after the date of this Security Agreement and until the Termination Date:

             a. Further Assurances;  Pledge of Instruments. At any time and from
time to time,  upon the  written  request of Lender  and at the sole  expense of
Debtor,  Debtor  shall  promptly  and duly  execute and deliver any and all such
further  instruments  and documents  and take such further  action as Lender may
reasonably deem desirable to obtain the full benefits of this Security Agreement
and of the  rights  and  powers  herein  granted,  including  (i) using its best
efforts to secure all consents and approvals  necessary or  appropriate  for the
assignment  to or for the benefit of Lender of any  License or Contract  held by
Debtor or in which Debtor has any
                                       -5-
<PAGE>
rights not  heretofore  assigned,  (ii)  filing any  financing  or  continuation
statements  under  the UCC with  respect  to the liens  and  security  interests
granted  hereunder  or  under  any  other  Loan  Document,   (iii)  transferring
Collateral to Lender's  possession (if such Collateral consists of Chattel Paper
or  if a  security  interest  in  such  Collateral  can  be  perfected  only  by
possession,  or, if  requested  by Lender),  and (iv) using its best  efforts to
obtain  waivers of liens from  landlords  and  mortgagees.  Debtor  also  hereby
authorizes  Lender to file any such financing or continuation  statement without
the signature of Debtor to the extent permitted by applicable law. If any amount
payable  under or in  connection  with any of the  Collateral is or shall become
evidenced by any Instrument, such Instrument,  other than checks received in the
ordinary course of business (which shall be deposited to a Collection  Account),
shall be duly  endorsed  in a manner  satisfactory  to Lender  immediately  upon
Debtor's receipt thereof and delivered to Lender.

             b. Maintenance of Records.  Debtor shall keep and maintain,  at its
own cost and  expense,  satisfactory  and  complete  records of the  Collateral,
including  a record of any and all  payments  received  and any and all  credits
granted  with  respect  to the  Collateral  and  all  other  dealings  with  the
Collateral. Debtor shall mark its books and records pertaining to the Collateral
to evidence this Security  Agreement and the security  interests granted hereby.
All Chattel Paper shall be marked with the following  legend:  "This writing and
the obligations evidenced or secured hereby are subject to the security interest
of General Electric Capital Corporation".  For Lender's further security, Debtor
agrees that Lender shall have a special property right and security  interest in
all of Debtor's  books and records  pertaining to the  Collateral  and, upon the
occurrence  and during the  continuation  of any Event of Default,  Debtor shall
deliver  and  turn  over  any  such  books  and  records  to  Lender  or to  its
representatives at any time on demand of Lender;  provided, that the Lender will
provide the Debtor with copies of such books and records at Debtor's request and
expense.  Prior to the  occurrence  of an Event of Default  and upon  reasonable
notice from Lender,  Debtor shall permit any representative of Lender to inspect
such books and records and shall provide  photocopies  thereof to Lender as more
specifically set forth in Section 5(g) below.

             c.  Indemnification.  In any suit,  proceeding or action brought by
Lender relating to any Account,  Chattel Paper,  Contract,  General  Intangible,
Instrument or Document for any sum owing thereunder, or to enforce any provision
of any Account,  Chattel Paper,  Contract,  General Intangible,  Instrument,  or
Document, Debtor shall save, indemnify and keep Lender harmless from and against
all  expense,  loss or  damage  suffered  by  reason  of any  defense,  set-off,
counterclaim,  recoupment  or reduction of liability  whatsoever  of the obligor
thereunder  arising out of a breach by Debtor of any  obligation  thereunder  or
arising out of any other agreement,  indebtedness or liability at any time owing
to, or in favor of, such obligor or its  successors  from  Debtor,  and all such
obligations of Debtor shall be and remain enforceable against, and only against,
Debtor and shall not be enforceable  against  Lender;  provided,  however,  that
Debtor  shall not be  required  to  indemnify  Lender  with  respect to any such
expense,  loss or damage suffered by Lender as a result of its gross  negligence
or willful  misconduct  in collecting  any sum owing under any Account,  Chattel
Paper, Contract, General Intangible, Instrument or Document.

             d.  Compliance  with  Terms  of  Accounts,  etc.  In  all  material
respects,  Debtor shall  perform and comply with all  obligations  in respect of
Accounts, Chattel Paper, Contracts, Licenses, Instruments and Documents, and all
other agreements to which it is a party or by which it or any of its property is
bound.
                                       -6-

             e.  Limitation  on Liens on  Collateral.  Debtor  shall not create,
permit or suffer to exist, and shall defend the Collateral against and take such
other  action as is necessary to remove,  any Lien on the  Collateral  except as
otherwise  permitted  pursuant to Section 7.6 of the Credit Agreement and except
for  Permitted  Exceptions.  Debtor shall  further  defend the right,  title and
interest of Lender in and to any of Debtor's rights under the Accounts,  Chattel
Paper,  Contracts,  Documents,  General  Intangibles  and Instruments and to the
Inventory,  and in and to the Proceeds  thereof,  against the Liens,  claims and
demands of all Persons whomsoever.

             f. Limitations on  Modifications of Accounts.  Subject to the terms
of the Credit Agreement,  upon the occurrence and during the continuation of any
Event of Default,  Debtor shall not, without Lender's prior written consent, (i)
grant any  extension  of the time of  payment  of any of the  Accounts,  Chattel
Paper,  Instruments or amounts due under any Contract, (ii) compromise or settle
the same for less than the full amount  thereof,  (iii) release,  in whole or in
part,  any Person  liable for the payment  thereof,  or (iv) allow any credit or
discount  whatsoever  thereon other than trade discounts granted in the ordinary
course of business of Debtor.

             g. Right of Inspection. Upon reasonable notice to Debtor (unless an
Event of Default  has  occurred  and is  continuing,  in which case no notice is
necessary),  Lender shall at all times have full and free access  during  normal
business hours to all the books and records and  correspondence  of Debtor,  and
Lender or its  representatives may examine the same, take extracts therefrom and
make  photocopies  thereof,  and Debtor agrees to render to Lender,  at Debtor's
cost and  expense,  such  clerical  and other  assistance  as may be  reasonably
requested with regard thereto. Upon reasonable notice to Debtor (unless an Event
of  Default  has  occurred  and is  continuing,  in  which  case  no  notice  is
necessary),  Lender and its  representatives  shall also have the right to enter
into and upon any  premises  where  any of the  Collateral  is  located  for the
purpose  of  inspecting  the same,  observing  its use or  otherwise  protecting
Lender's interests in the Collateral.

             h.  Continuous  Perfection.  Debtor  shall  not  change  its  name,
identity or corporate  structure in any manner which might make any financing or
continuation  statement filed in connection herewith seriously misleading within
the  meaning  of  section  9-402(7)  of the  UCC or any  other  then  applicable
provision of the UCC unless  Debtor shall have given Lender at least thirty (30)
days'  prior  written  notice  thereof  and shall have taken all action (or made
arrangements to take such action  substantially  simultaneously with such change
if it is  impossible  to take such action in advance)  necessary  or  reasonably
requested by Lender to amend such financing statement or continuation  statement
so that it is not seriously misleading.

             6. LENDER'S APPOINTMENT AS ATTORNEY-IN-FACT.

             a. Debtor hereby  irrevocably  constitutes  and appoints Lender and
any officer or agent thereof,  with full power of substitution,  as its true and

time in Lender's  reasonable  discretion,  for the  purpose of carrying  out the

following:

                    (i) in the name of  Debtor,  in its own  name or  otherwise,
             take  possession  of,  endorse and  receive  payment of any checks,
             drafts, notes, acceptances, or other Instruments for the payment of
             monies due under any Collateral;

                    (ii) continue any insurance  existing  pursuant to the terms
             of the  Loan  Documents,  and pay all or any  part of the  premiums
             therefor and the costs thereof; and

                    (iii)  receive  payment of any and all monies,  claims,  and
             other amounts due or to become due at any time arising out of or in
             respect of any Collateral.

             b. Debtor hereby  irrevocably  constitutes  and appoints Lender and
any officer or agent thereof,  with full power of substitution,  as its true and
lawful  attorney-in-fact  with full irrevocable power and authority in the place
and stead of Debtor  and in the name of Debtor or in its own name,  from time to
time in Lender's  reasonable  discretion,  for the  purpose of carrying  out the
terms of this Security Agreement,  to take any and all appropriate action and to
execute and deliver any and all documents and  instruments  which may reasonably
be necessary or desirable to accomplish the purposes of this Security  Agreement
and, without  limiting the generality of the foregoing,  hereby grants to Lender
the power and right,  on behalf of Debtor,  upon notice to (which  notice may be
simultaneous  with such  action)  but  without  the assent of  Debtor,  upon the
occurrence  and  during  the  continuation  of an  Event of  Default,  to do the
following:

                    (i) ask, demand, collect,  receive and give acquittances and
             receipts  for any and all  money  due or to  become  due  under any
             Collateral;

                    (ii) pay or discharge taxes,  liens,  security interest,  or
             other  encumbrances  levied or placed on or threatened  against the
             Collateral;

                    (iii)  obtain any  insurance  called for by the terms of the
             Loan Documents and pay all or any part of the premiums therefor and
             costs thereof;

                    (iv)  direct any party  liable for any  payment  under or in
             respect  of any of the  Collateral  to make  payment of any and all
             monies due or to become due thereunder,
                                       -8-
<PAGE>
             directly to Lender or as Lender shall direct;

                    (v) sign and endorse any invoices, freight or express bills,
             bills of lading,  storage or  warehouse  receipts,  drafts  against
             debtors, assignments, verifications, and notices in connection with
             accounts  and  other  documents  constituting  or  related  to  the
             Collateral;

                    (vi)  settle,  compromise  or adjust  any suit,  action,  or
             proceeding described above and, in connection therewith,  give such
             discharges or releases as Lender may deem appropriate;

                    (vii) file any claim or take or commence any other action or
             proceeding  in any court of law or equity or  otherwise  reasonably
             deemed  appropriate by Lender for the purpose of collecting any and
             all such monies due under any Collateral whenever payable;

                    (viii)   commence  and  prosecute  any  suits,   actions  or
             proceedings of law or equity in any court of competent jurisdiction
             to collect the  Collateral  or any part  thereof and to enforce any
             other right in respect of any Collateral;

                    (ix) defend any suit,  action or proceeding  brought against
             Debtor  with  respect to any  Collateral  if Debtor does not defend
             such suit,  action or proceeding or if Lender  reasonably  believes
             that  Debtor is not  pursuing  such  defense in a manner  that will
             maximize the recovery with respect to such Collateral;

                    (x) license  or, to the extent  permitted  by an  applicable
             license,  sublicense  whether general,  specific or otherwise,  and
             whether  on an  exclusive  or  non-exclusive  basis,  any Patent or
             Trademark throughout the world for such or terms on such conditions
             and in such manner as Lender shall,  in its reasonable  discretion,
             determine; and

                    (xi) sell, transfer, pledge, make any agreement with respect
             to,  or  otherwise  deal  with any of the  Collateral  as fully and
             completely as though Lender were the absolute owner thereof for all
             purposes,  and to do, at Lender's option and Debtor's  expense,  at
             any time,  or from time to time,  all acts and things  which Lender
             reasonably  deems necessary to perfect,  preserve,  or realize upon
             the  Collateral  and  Lender's  Lien thereon in order to effect the
             intent of this Security Agreement,  all as fully and effectively as
             Debtor might do.

             c. Debtor hereby ratifies, to the extent permitted by law, all that
said attorneys shall lawfully do or cause to be done by virtue hereof. The power
of  attorney  granted  pursuant  to this  Section 6 is a power  coupled  with an
interest and shall be irrevocable until the Termination Date.
                                       -9-
<PAGE>
             d. The powers  conferred on Lender  hereunder are solely to protect
Lender's  interests in the  Collateral  and shall not impose any duty upon it to
exercise any such powers.  Lender shall be accountable  only for amounts that it
actually  receives as a result of the exercise of such powers.  None of Lender's
officers,  directors,  employees, agents or representatives shall be responsible
to Debtor for any failure to act,  and in taking  affirmative  action,  shall be
liable only to the extent that such Persons are finally determined by a court of
competent jurisdiction to be guilty of gross negligence or willful misconduct.

             e. Following the occurrence and during the continuation of an Event
of Default, Debtor also authorizes Lender, at any time and from time to time, to
(i)  communicate  in its own name with any party to any Contract  with regard to
the  assignment  of the  right,  title and  interest  of Debtor in and under the
Contracts and other  matters  relating  thereto and (ii) execute,  in connection
with the sale provided for in Section 8 hereof, any endorsements, assignments or
other instruments of conveyance or transfer with respect to the Collateral.

             7. PERFORMANCE BY LENDER OF DEBTOR'S SECURED OBLIGATIONS. If Debtor
fails to perform or comply with any of its agreements contained herein or in any
of the other Loan  Documents,  and Lender,  as provided for by the terms of this
Security  Agreement or any of the other Loan Documents,  shall itself perform or
comply,  or otherwise cause  performance of or compliance,  with such agreement,
the  reasonable  expenses,  including  attorneys'  fees,  of Lender  incurred in
connection with such  performance or compliance,  together with interest thereon
at the rate then in effect in respect of the  Revolving  Credit  Loan,  shall be
payable by Debtor to Lender on demand and shall constitute  Secured  Obligations
secured hereby.

             8. REMEDIES; RIGHTS UPON DEFAULT.

             a. If any Event of Default  shall occur and be  continuing,  Lender
may exercise in addition to all other  rights and  remedies  granted to it under
this Security  Agreement,  the Credit  Agreement,  the other Loan  Documents and
under any other instrument or agreement  securing,  evidencing,  guaranteeing or
otherwise relating to the Secured  Obligations,  all rights and remedies that it
has as a secured  party under the UCC.  Without  limiting the  generality of the
foregoing, Debtor expressly agrees that in any such event Lender, without demand
of performance or other demand,  advertisement or notice of any kind (except the
notice  specified  below of time and  place of public  or  private  sale and any
notice  expressly  required by the Guaranty  Agreement) to or upon Debtor or any
other  Person  (all and each of which  demands,  advertisements  and notices are
hereby  expressly  waived to the maximum  extent  permitted by the UCC and other
applicable  law),  may  forthwith  enter upon the  premises of Debtor  where any
Collateral is located through self-help, without judicial process, without first
obtaining a final judgment or giving Debtor notice and opportunity for a hearing
on Lender's  claim or action,  and without  paying rent to Debtor,  and collect,
receive, assemble, process,  appropriate and realize upon the Collateral, or any
part thereof,  and may forthwith sell, lease,  assign, give an option or options
to purchase,  or sell or otherwise  dispose of and deliver said  Collateral  (or
contract to do so),  or any part  thereof,  in one or more  parcels at public or
private sale or sales,  at any exchange at such prices as it may deem best,  for
cash or on credit or for future delivery without  assumption of any credit risk.
Lender shall have the right upon any such public sale or sales,
                                      -10-
<PAGE>
and, to the extent  permitted by law,  upon any such  private sale or sales,  to
purchase for the benefit of Lender the whole or any part of said  Collateral  so
sold,  free of any right or equity of  redemption,  which  equity of  redemption
Debtor hereby  releases.  Such sales may be adjourned and continued from time to
time with or without  notice.  Lender shall have the right to conduct such sales
on  Debtor's  premises  or  elsewhere  and shall have the right to use  Debtor's
premises  without  charge  for such  time or times as  Lender  reasonably  deems
necessary or advisable.

             Debtor  further  agrees,  at  Lender's  request,  to  assemble  the
Collateral  and make it  available  to  Lender  at  places  which  Lender  shall
reasonably  select,  whether at Debtor's premises or elsewhere.  Until Lender is
able to effect a sale, lease, or other  disposition of Collateral,  Lender shall
have the right to use, operate or administer  Collateral on behalf of Lender, or
any part thereof,  to the extent that it reasonably  deems  appropriate  for the
purpose  of  preserving  Collateral  or its  value  or  for  any  other  purpose
reasonably  deemed  appropriate  by Lender.  Lender shall have no  obligation to
Debtor to  maintain or preserve  the rights of Debtor as against  third  parties
with respect to  Collateral  while  Collateral  is in the  possession of Lender.
Lender may, if it so elects and, to the extent not prohibited by applicable law,
seek the  appointment  of a receiver or keeper to take  possession of Collateral
and to enforce any of Lender's remedies with respect to such appointment without
prior  notice  or  hearing.  Lender  shall  apply the net  proceeds  of any such
collection, recovery, receipt, appropriation, realization or sale as provided in
Section 8(d) hereof, Debtor remaining liable for any deficiency remaining unpaid
after such  application,  and only after so paying  over such net  proceeds  and
after the payment by Lender of any other  amount  required by any  provision  of
law,  including  section  9-504(1)(c)  of the UCC (but  only  after  Lender  has
received  what  Lender  considers  reasonable  proof  of a  subordinate  party's
security  interest),  need Lender account for the surplus, if any, to Debtor. To
the maximum  extent  permitted  by  applicable  law,  Debtor  waives all claims,
damages,  and demands against Lender arising out of the repossession,  retention
or sale of the  Collateral  except  to the  extent  that a  court  of  competent
jurisdiction  issues a final  determination  that such  claims or damages  arise
solely out of the gross negligence or willful  misconduct of such party.  Debtor
agrees that ten (10) days'  prior  notice by Lender of the time and place of any
public  sale or of the  time  after  which a  private  sale  may  take  place is
reasonable  notification  of such  matters.  Debtor shall remain  liable for any
deficiency  if the proceeds of any sale or  disposition  of the  Collateral  are
insufficient  to pay all amounts to which Lender is entitled,  Debtor also being
liable for any  reasonable  attorneys'  fees  incurred by Lender to collect such
deficiency.

             b.  Debtor  agrees to pay any and all  reasonable  costs of Lender,
including,   without  limitation,   reasonable   attorneys'  fees,  incurred  in
connection with the enforcement of any of its rights and remedies hereunder.

             c. Except as otherwise  specifically provided herein or in the Loan
Documents,  Debtor hereby waives presentment,  demand, protest or any notice (to
the maximum extent  permitted by applicable  law) of any kind in connection with
the Loan Documents, the Security Agreement or any Collateral.

             d. The Proceeds of any sale,  disposition or other realization upon
all or any part of the  Collateral  shall be distributed by Lender upon receipt,
in the following order of priorities:
                                      -11-
<PAGE>
                    first, to Lender in an amount  sufficient to pay in full the
             reasonable  expenses  of  Lender  in  connection  with  such  sale,
             disposition   or  other   realization,   including   all  expenses,
             liabilities  and advances  incurred or made by Lender in connection
             therewith, including reasonable attorney's fees;

                    second,  to Lender  in an  amount  equal to the then due and
             unpaid accrued interest,  fees and prepayment premiums,  if any, on
             the Secured Obligations;

                    third,  to  Lender in an  amount  equal to any other  unpaid
             Secured Obligations or amounts owed, if any, in connection with the
             Secured Obligations; and

                    finally,  upon  payment  in  full  of  all  of  the  Secured
             Obligations,  to Debtor or its representatives or to whomsoever may
             be  lawfully  entitled  to  receive  the  same,  or as a  court  of
             competent jurisdiction may direct.

             9. GRANT OF LICENSE TO USE PATENT AND TRADEMARK COLLATERAL. For the
purpose of  enabling  Lender to exercise  rights and  remedies  under  Section 8
hereof  (including,  without limiting the terms of Section 8 hereof, in order to
take possession of, hold, preserve,  process, assemble, prepare for sale, market
for sale, sell or otherwise  dispose of Collateral) at such time as Lender shall
be lawfully entitled to exercise such rights and remedies,  Debtor hereby grants
to Lender an irrevocable,  non-exclusive license (exercisable without payment of
royalty or other compensation to Debtor) to use, transfer, license or sublicense
any  Patent,  Trademark,  trade  secret,  or  copyright  now owned or  hereafter
acquired by Debtor, and wherever the same may be located,  and including in such
license reasonable access to all media in which any of the licensed items may be
recorded or stored and to all  computer  and  automatic  machinery  software and
programs  used for the  compilation  or  printout  thereof;  provided  that such
license  shall be  exercisable  only at such time as the  Lender  shall have the
right to exercise its rights and remedies under Section 8 hereof.

             10.  LIMITATION ON LENDER'S DUTY IN RESPECT OF  COLLATERAL.  Lender
shall use  reasonable  care with respect to the  Collateral in its possession or
under its control.  Lender shall not have any other duty as to any Collateral in
its  possession  or  control  or in the  possession  or  control of any agent or
nominee of Lender,  or any income  thereon or as to the  preservation  of rights
against  prior  parties or any other  rights  pertaining  thereto.  Lender shall
account for any monies  received by Lender in respect of any  foreclosure  on or
disposition of the Collateral.

             11.  REINSTATEMENT.  This Agreement  shall remain in full force and
effect and continue to be  effective  should any petition be filed by or against
Debtor for liquidation or reorganization, should Debtor become insolvent or make
an  assignment  for the benefit of  creditors or should a receiver or trustee be
appointed for all or any significant part of Debtor's assets, and shall continue
to be effective or be reinstated, as the case may be, if at any time payment and
performance of the Secured  Obligations,  or any part thereof,  is,  pursuant to
applicable law, rescinded or reduced in amount, or must otherwise be restored or
returned  by any  obligee of the  Secured  Obligations,  whether as a  "voidable
preference,"  "fraudulent  conveyance," or otherwise, all as though such payment
or performance had not been made. In
                                      -12-
<PAGE>
the event that any payment, or any part thereof, is rescinded, reduced, restored
or returned, the Secured Obligations shall be reinstated and deemed reduced only
by such amount paid and not so rescinded, reduced, restored or returned.

             12. NOTICES.  Except as otherwise  provided herein,  whenever it is
provided herein that any notice, demand, request, consent, approval, declaration
or other  communication  shall or may be given to or served  upon  either of the
parties by the other party, or whenever either of the parties desires to give or
serve upon the other  party any  communication  with  respect  to this  Security
Agreement, each such notice, demand, request, consent, approval,  declaration or
other  communication  shall be in writing and shall be given in the manner,  and
deemed received, as provided for in Section 11 of the Guaranty Agreement.

             13.  SEVERABILITY;   COMPLETE  AGREEMENT.  Any  provision  of  this
Security  Agreement  which is prohibited or  unenforceable  in any  jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such prohibition
or unenforceability  without  invalidating the remaining  provisions hereof, and
any  such  prohibition  or   unenforceability  in  any  jurisdiction  shall  not
invalidate or render  unenforceable  such  provision in any other  jurisdiction.
This Security  Agreement is to be read,  construed and applied together with the
Credit Agreement and the other Loan Documents,  which, taken together, set forth
the complete  understanding  and  agreement of Lender and Debtor with respect to
the matters  referred to herein and therein and supersede all prior  agreements,
understandings or inducements whether express or implied, or oral or written.

             14. NO WAIVER;  CUMULATIVE  REMEDIES.  Lender shall not by any act,
delay,  omission  or  otherwise  be deemed to have  waived  any of its rights or
remedies  hereunder,  and no waiver shall be valid unless in writing,  signed by
Lender and then only to the extent  therein set forth. A waiver by Lender of any
right or remedy hereunder on any one occasion shall not be construed as a bar to
any  right or  remedy  which  Lender  would  otherwise  have  had on any  future
occasion.  No failure to  exercise  nor any delay in  exercising  on the part of
Lender,  any right,  power or  privilege  hereunder,  shall  operate as a waiver
thereof,  nor shall any  single  or  partial  exercise  of any  right,  power or
privilege  hereunder  preclude  any  other or  future  exercise  thereof  or the
exercise  of any other  right,  power or  privilege.  The  rights  and  remedies
hereunder  provided are cumulative and may be exercised  singly or concurrently,
and are not  exclusive of any rights and remedies  provided by law.  None of the
terms or provisions of this Security Agreement may be waived, altered,  modified
or amended  except by an  instrument  in  writing,  duly  executed by Lender and
Debtor.

             15.  LIMITATION BY LAW; TIME OF ESSENCE.  All rights,  remedies and
powers  provided in this Security  Agreement may be exercised only to the extent
that the exercise thereof does not violate any applicable  provision of law, and
all the provisions of this Security  Agreement are intended to be subject to all
applicable mandatory provisions of law that may be controlling and to be limited
to the extent  necessary so that they shall not render this  Security  Agreement
invalid,  unenforceable,  in whole or in part,  or not  entitled to be recorded,
registered,  or filed under the provisions of any applicable law. Time is of the
essence of this Security Agreement.

             16. TERMINATION OF THIS SECURITY AGREEMENT. Subject to
                                      -13-
<PAGE>
             Section 11 hereof, this Security Agreement shall terminate upon the
Termination Date and all of Lender's rights,  titles and interests in and to the
Collateral  hereunder  shall be  automatically  terminated  and released on such
date.

             17.  SUCCESSORS  AND  ASSIGNS.  This  Security  Agreement  and  all
obligations of Debtor hereunder shall be binding upon the successors and assigns
of Debtor, and shall, together with the rights and remedies of Lender hereunder,
inure to the benefit of Lender, all future holders of any instrument  evidencing
any of the Secured  Obligations and their respective  successors and assigns. No
sales  of  participations,   other  sales,   assignments,   transfers  or  other
dispositions  of any agreement  governing or instrument  evidencing  the Secured
Obligations  or any  portion  thereof or  interest  therein  shall in any manner
affect the security interest granted to Lender hereunder. Debtor may not assign,
sell or otherwise transfer an interest in this Security Agreement.

             18.  EXECUTION IN  COUNTERPARTS.  This  Security  Agreement  may be
executed in any number of  counterparts,  each of which shall  collectively  and
separately constitute one agreement.

             19.  GOVERNING LAW;  CONSENT TO JURISDICTION  AND VENUE.  EXCEPT AS
OTHERWISE  EXPRESSLY  PROVIDED IN ANY OF THE LOAN  DOCUMENTS,  IN ALL  RESPECTS,
INCLUDING ALL MATTERS OF CONSTRUCTION,  VALIDITY AND PERFORMANCE,  THIS SECURITY
AGREEMENT AND THE SECURED  OBLIGATIONS  ARISING  HEREUNDER SHALL BE GOVERNED BY,
AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK
APPLICABLE  TO CONTRACTS  MADE AND PERFORMED IN SUCH STATE,  AND ANY  APPLICABLE
LAWS OF THE UNITED STATES OF AMERICA. DEBTOR HEREBY CONSENTS AND AGREES THAT THE
STATE OR FEDERAL  COURTS  LOCATED IN THE BOROUGH OF MANHATTAN,  NEW YORK,  SHALL
HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN
DEBTOR AND LENDER PERTAINING TO THIS SECURITY AGREEMENT OR TO ANY MATTER ARISING
OUT OF OR RELATING TO THIS SECURITY  AGREEMENT,  THE CREDIT  AGREEMENT OR ANY OF
THE OTHER LOAN DOCUMENTS,  PROVIDED, THAT LENDER AND DEBTOR ACKNOWLEDGE THAT ANY
APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF THE
BOROUGH OF  MANHATTAN,  NEW YORK AND,  PROVIDED,  FURTHER,  THAT NOTHING IN THIS
AGREEMENT  SHALL BE DEEMED OR OPERATE TO PRECLUDE  LENDER FROM  BRINGING SUIT OR
TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO REALIZE ON THE COLLATERAL
OR ANY OTHER SECURITY FOR THE SECURED  OBLIGATIONS,  OR TO ENFORCE A JUDGMENT OR
OTHER COURT ORDER IN FAVOR OF LENDER AND,  PROVIDED,  FURTHER,  THAT  NOTHING IN
THIS  AGREEMENT  SHALL BE  DEEMED TO  PRECLUDE  THE  DEBTOR  FROM  PURSUING  ANY
COMPULSORY  COUNTERCLAIM  IN ANY  PROCEEDING  BROUGHT  BY THE LENDER IN ANY SUCH
OTHER  JURISDICTION.  DEBTOR  EXPRESSLY  SUBMITS AND CONSENTS IN ADVANCE TO SUCH
JURISDICTION  IN ANY  ACTION OR SUIT  COMMENCED  IN ANY SUCH  COURT,  AND DEBTOR
HEREBY  WAIVES ANY  OBJECTION  WHICH DEBTOR MAY HAVE BASED UPON LACK OF PERSONAL
JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY
                                      -14-
<PAGE>
CONSENTS  TO THE  GRANTING  OF SUCH  LEGAL  OR  EQUITABLE  RELIEF  AS IS  DEEMED
APPROPRIATE BY SUCH COURT. DEBTOR HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS,
COMPLAINT  AND OTHER  PROCESS  ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT
SERVICE OF SUCH SUMMONS,  COMPLAINTS AND OTHER PROCESS MAY BE MADE BY REGISTERED
OR  CERTIFIED  MAIL  ADDRESSED TO DEBTOR IN  ACCORDANCE  WITH SECTION 12 OF THIS
SECURITY  AGREEMENT AND THAT SERVICE SO MADE SHALL BE DEEMED  COMPLETED UPON THE
EARLIER OF DEBTOR'S  ACTUAL  RECEIPT  THEREOF OR FIVE DAYS AFTER  DEPOSIT IN THE
U.S. MAILS, PROPER POSTAGE PREPAID.

             21.  MUTUAL  WAIVER OF JURY  TRIAL.  BECAUSE  DISPUTES  ARISING  IN
CONNECTION WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY
RESOLVED BY AN  EXPERIENCED  AND EXPERT  PERSON AND THE PARTIES WISH  APPLICABLE
STATE AND FEDERAL LAWS TO APPLY  (RATHER THAN  ARBITRATION  RULES),  THE PARTIES
DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS.
THEREFORE,  TO ACHIEVE THE BEST  COMBINATION  OF THE  BENEFITS  OF THE  JUDICIAL
SYSTEM AND OF  ARBITRATION,  THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY
IN ANY ACTION,  SUIT,  OR  PROCEEDING  BROUGHT TO RESOLVE ANY  DISPUTE,  WHETHER
SOUNDING IN CONTRACT,  TORT, OR OTHERWISE,  BETWEEN THE PARTIES  ARISING OUT OF,
CONNECTED  WITH,  RELATED  TO, OR  INCIDENTAL  TO THE  RELATIONSHIP  ESTABLISHED
BETWEEN THEM IN CONNECTION WITH, THIS SECURITY AGREEMENT,  THE CREDIT AGREEMENT,
OR ANY OF THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS RELATED THERETO.

             IN WITNESS WHEREOF, Debtor has caused this Security Agreement to be
executed and delivered by its duly  authorized  officer as of the date first set
forth above.

                               GUARANTY AGREEMENT


                THIS GUARANTY AGREEMENT (this "Guaranty"),  dated as of June 11,
1997, made by ARIZONA REPAIR SERVICES, INC., an Arizona corporation ("ARS"), and
ENHANCED SYSTEMS,  INC., an Arizona corporation ("ESI", ARS and ESI are referred
to herein  individually as a "Guarantor" and collectively as the  "Guarantors"),
in favor of GENERAL  ELECTRIC CAPITAL  CORPORATION,  a New York corporation (the
"Guaranteed Party").

                              W I T N E S S E T H:
                              - - - - - - - - - -

                WHEREAS,   Vodavi  Communications   Systems,  Inc.,  an  Arizona
corporation  formerly known as V Technology  Acquisition Corp. (the "Borrower"),
and  the  Guaranteed  Party  are  parties  to an  Amended  and  Restated  Credit
Agreement,  dated as of April 11, 1994, as amended and restated  effective as of
June 11, 1997 (as the same may hereafter be amended,  restated,  supplemented or
otherwise modified from time to time, the "Credit Agreement";  the terms defined
therein and not otherwise  defined herein being used herein as therein defined),
pursuant to which the Guaranteed  Party has committed to make a Revolving Credit
Loan available to the Borrower; and

                WHEREAS,  the Borrower and the  Guarantors  share an identity of
interests as members of a  consolidated  group of  companies  engaged in similar
businesses,  and the  making  of the  Revolving  Credit  Loan  available  to the
Borrower will facilitate  expansion and enhance the overall  financial  strength
and stability of the Borrower's corporate group, including the Guarantors; and

                WHEREAS,  it is a condition  precedent to the Guaranteed Party's
obligations  to make the  Revolving  Credit  Loan  available  under  the  Credit
Agreement  that the  Guarantors  execute  and  deliver  this  Guaranty,  and the
Guarantors desire to execute and deliver this Guaranty to satisfy such condition
precedent.

                  NOW, THEREFORE,  in consideration of the premises and in order
to induce the Guaranteed Party to make the Revolving Credit Loan available under
the Credit Agreement, each Guarantor hereby agrees as follows:

                1.  Guaranty  of   Obligations.   (a)  Each   Guarantor   hereby
absolutely,  unconditionally and irrevocably  guarantees to the Guaranteed Party
the prompt payment when due,  whether at stated  maturity,  by  acceleration  or
otherwise, of the Revolving Credit Loan and all other Obligations (as defined in
the Credit Agreement, and including all renewals, extensions, modifications, and
refinancings  thereof)  now  or  hereafter  existing,   whether  for  principal,
interest,  fees, expenses or otherwise,  and all expenses (including  reasonable
attorney's fees and expenses)  incurred by the Guaranteed Party in enforcing any
of its rights under the Credit  Agreement and the other Loan  Documents  (all of
the foregoing, collectively, the "Guaranteed Obligations"). Any and all payments
made by any  Guarantor  hereunder  shall be made free and  clear of and  without
deduction for any set-off, counterclaim, or
<PAGE>
withholdings so that, in each case, the Guaranteed  Party shall receive the full
amount  that it would  otherwise  be  entitled  to receive  with  respect to the
Guaranteed Obligations.

                (b) Each Guarantor acknowledges and agrees that this Guaranty is
a guaranty  of payment  and not of  collection  and that the  liability  of such
Guarantor  under this  Guaranty  shall be immediate and primary and shall not be
contingent  upon the  exercise or  enforcement  by the  Guaranteed  Party of any
remedies  the  Guaranteed  Party  may have  against  the  Borrower  or any other
Guarantor any other person or the  enforcement of any lien or  realization  upon
any  collateral  the  Guaranteed  Party may at any time  possess  for any of the
Guaranteed Obligations.

                2. Maximum Liability;  Contribution.  (a) It is the intention of
each  of  the  Guarantors  and  the  Guaranteed   Party  that  each  Guarantor's
obligations hereunder shall be in, but not in excess of, the maximum amount (the
"Maximum Guaranty Liability") permitted by applicable federal bankruptcy,  state
insolvency,  fraudulent  conveyance  or  transfer or similar  laws  ("Applicable
Law"). To that end, but only to the extent such  obligations  would otherwise be
subject to avoidance under Applicable Law if any Guarantor is not deemed to have
received valuable  consideration,  fair value or reasonably equivalent value for
its obligations  hereunder,  each Guarantor's  respective  obligations hereunder
shall be reduced to that amount which,  after giving effect  thereto,  would not
render such Guarantor insolvent, or leave such Guarantor with unreasonably small
capital to conduct its business,  or cause such Guarantor to have incurred debts
(or  intended to have  incurred  debts)  beyond its ability to pay such debts as
they mature, at the time such obligations are deemed to have been incurred under
Applicable Law. As used herein,  the terms "insolvent" and  "unreasonably  small
capital" shall likewise be determined in accordance  with  Applicable  Law. This
Section  is  intended  solely to  preserve  the rights of the  Guaranteed  Party
hereunder to the maximum  extent  permitted by  Applicable  Law, and neither the
Guarantors  nor any  other  Persons  shall  have any right or claim  under  this
Section  that would not  otherwise  be  available  under  Applicable  Law.  Each
Guarantor  agrees that the Guaranteed  Obligations may at any time and from time
to  time  exceed  the  Maximum  Guaranty  Liability  of such  Guarantor  without
impairing  this Guaranty or affecting the rights and remedies of the  Guaranteed
Party hereunder.

                (b) If and to the extent that any  Guarantor  shall,  under this
Guaranty  make a payment (a  "Guarantor  Payment")  of all or any portion of the
Guaranteed  Obligations,  then such Guarantor  shall be entitled to contribution
and  indemnification  from,  and  shall  be  reimbursed  by,  each of the  other
Guarantors  (collectively the "Contributing  Guarantors") in an amount, for each
such Contributing Guarantor,  equal to a fraction of such Guarantor Payment, the
numerator of which fraction is such Contributing Guarantor's Allocable Amount of
such  Guarantor  Payment and the  denominator  of which is the sum of all of the
Allocable  Amounts  of  such  Guarantor  Payment  of  all  of  the  Contributing
Guarantors.  As of any date of  determination  thereof  and with  respect to any
Guarantor Payment,  the "Allocable Amount" of each Contributing  Guarantor shall
be equal to the maximum amount of liability which could be asserted against such
Contributing  Guarantor  under this  Guaranty  with  respect  to such  Guarantor
Payment  without (i)  rendering  such  Contributing  Guarantor  insolvent,  (ii)
                                      -2-
<PAGE>
leaving such Contributing  Guarantor with unreasonably  small capital to conduct
its  business,  or (iii)  causing such  Contributing  Guarantor to have incurred
debts  beyond  its  ability to pay such  debts as they  mature.  As used in this
Section 2(b), the terms  "insolvent" and  "unreasonably  small capital" shall be
determined in accordance  with  Applicable  Laws.  This Section 2(b) is intended
only to define  the  relative  rights and  obligations  of the  Guarantors  with
respect to any and all Guarantor Payments, and nothing set forth in this Section
2(b) is intended to or shall otherwise modify,  affect or impair the obligations
of the  Guarantors,  jointly and severally,  to pay any or all of the Guaranteed
Obligations as and when the same shall become due and payable in accordance with
the terms of this Guaranty.  Each of the Guarantors hereby acknowledges that the
rights of contribution and indemnification  hereunder shall constitute assets in
favor of each Guarantor to which such contribution and  indemnification is owing
hereunder.  The agreements contained in this Section 2(b) shall continue in full
force and effect and may not be terminated or otherwise revoked by any Guarantor
until all of the Guaranteed Obligations have been indefeasibly paid in full, all
Commitments  under the Credit  Agreement  have  terminated  or expired,  and the
Credit  Agreement  and the other Loan  Documents  shall have been  terminated in
accordance with the terms thereof.

                3. Guaranty Absolute.  This Guaranty shall in all respects be an
absolute,  unconditional  and irrevocable  guaranty of payment of the Guaranteed
Obligations and each Guarantor  guarantees that the Guaranteed  Obligations will
be paid strictly in accordance  with the terms of the Loan Documents under which
they arise,  regardless  of any law,  regulation  or order now or  hereafter  in
effect in any  jurisdiction  affecting  any of such  terms or the  rights of the
Guaranteed  Party with respect  thereto.  The liability of each Guarantor  under
this Guaranty shall remain in full force and effect without regard to, and shall
not be  released,  suspended,  discharged,  terminated,  modified  or  otherwise
affected  by  any  circumstance  or  occurrence  whatsoever,  including  without
limitation any of the following  (whether or not any Guarantor  consents thereto
or has notice thereof): (i) any change in or waiver of the time, place or manner
of payment,  or any other term,  of any of the  Guaranteed  Obligations  or Loan
Documents,  any waiver of or any  renewal,  extension,  increase,  amendment  or
modification  of or addition,  consent or supplement to or deletion from, or any
other  action  or  inaction  under  or in  respect  of,  any of  the  Guaranteed
Obligations  or Loan  Documents or any other  document,  instrument or agreement
referred  to therein or any  assignment  or  transfer  of any of the  Guaranteed
Obligations  or  Loan  Documents;  (ii)  any  lack  of  validity,   legality  or
enforceability  of any of the  Guaranteed  Obligations  or Loan Documents or any
other  document,  instrument,  or  agreement  referred  to  therein  or  of  any
assignment  or transfer of any of the  foregoing;  (iii) any  furnishing  to the
Guaranteed  Party  of any  additional  collateral  for  any  of  the  Guaranteed
Obligations or any sale,  exchange,  release or surrender of, or realization on,
any  collateral  for any of the  Guaranteed  Obligations;  (iv) any  settlement,
release or compromise of any of the Guaranteed  Obligations  or Loan  Documents,
any collateral therefor,  or any liability of any other party (including without
limitation  any  other   guarantor)  with  respect  to  any  of  the  Guaranteed
Obligations or Loan  Documents,  or any  subordination  of payment of any of the
Guaranteed  Obligations to the payment of any other  indebtedness,  liability or
obligation  of the Borrower;  (v) any  bankruptcy,  insolvency,  reorganization,
composition,  adjustment,  merger,  consolidation,  dissolution,  liquidation or
                                      -3-
<PAGE>
other like proceeding or occurrence relating to the Borrower or any other change
in  the   ownership,   composition   or  nature  of  the   Borrower;   (vi)  any
non-perfection,  subordination,  release,  avoidability  or  voidability  of any
security interest,  security title, pledge,  collateral assignment or other lien
of the Guaranteed Party on any collateral for any of the Guaranteed  Obligations
or this  Guaranty;  (vii) any  application  of sums paid by the  Borrower or any
other person with respect to any of the  Guaranteed  Obligations,  except to the
extent actually applied against the Guaranteed  Obligations,  regardless of what
other  liabilities  of the  Borrower  remain  unpaid;  (viii) the failure of the
Guaranteed Party to assert any claim or demand or to enforce any right or remedy
against the Borrower or any other person  (including any other  guarantor of any
of the Guaranteed Obligations) under the provisions of any of the Loan Documents
or otherwise,  or any failure of the  Guaranteed  Party to exercise any right or
remedy  against  any  other  guarantor  of or  any  collateral  for  any  of the
Guaranteed  Obligations;  (ix) any other act or failure to act by the Guaranteed
Party which may adversely  affect any Guarantor;  or (x) any other  circumstance
which might  otherwise  constitute  a defense  against,  or a legal or equitable
discharge of, any Guarantor's liability under this Guaranty.

                4. Guaranty  Continuing;  Reinstatement.  This Guaranty shall in
all  respects  be a  continuing  and  irrevocable  guaranty of payment and shall
remain in full force and effect  until the  Termination  Date.  If claim is ever
made upon the Guaranteed  Party for repayment or recovery of any amount received
by the  Guaranteed  Party in  payment  or on  account  of any of the  Guaranteed
Obligations,  and if the  Guaranteed  Party repays all or part of said amount by
reason of (i) any judgment,  decree or order of any court or administrative body
having jurisdiction over the Guaranteed Party or any of its property or (ii) any
settlement or compromise of any such claim effected by the Guaranteed Party with
any such  claimant  (including  without  limitation  the  Borrower or a trustee,
conservator or receiver for the Borrower), then and in such event each Guarantor
agrees that any such judgment,  decree, order, settlement or compromise shall be
binding upon such Guarantor,  notwithstanding  any revocation or cancellation of
this Guaranty or of any of the Loan  Documents,  and each Guarantor shall be and
remain  liable to the  Guaranteed  Party  hereunder  for the amount so repaid or
recovered to the same extent as if such amount had never originally been paid to
the Guaranteed  Party and each  Guarantor's  obligations  and liabilities to the
Guaranteed Party under this Guaranty shall be reinstated to such extent and this
Guaranty and any  collateral  for this  Guaranty  shall remain in full force and
effect (or shall be reinstated) to such extent.  Each Guarantor hereby expressly
waives the benefit of any applicable  statute of limitations  and agrees that it
shall be liable  under this  Guaranty  whenever  the  Guaranteed  Party seeks to
enforce such liability against such Guarantor or its property.

                5. Waivers and  Consents.  Each  Guarantor  hereby  waives:  (i)
notice of acceptance of this Guaranty by the  Guaranteed  Party;  (ii) notice of
the  creation,  existence,  acquisition,  extension,  or  renewal  of any of the
Guaranteed Obligations; (iii) notice of the amount of the Guaranteed Obligations
outstanding from time to time,  subject,  however,  to each Guarantor's right to
make inquiry of the  Guaranteed  Party at reasonable  intervals to ascertain the
amount of  Guaranteed  Obligations  then  outstanding;  (iv) except as otherwise
expressly  required under the Loan Documents,  notice of any default or event of
default under any of the Loan Documents or with respect to any of the Guaranteed
Obligations or notice of 
                                      -4-
<PAGE>
any other  adverse  change in the  Borrower's  financial  condition  or means or
ability to pay any of the  Guaranteed  Obligations  or perform  its  obligations
under any of the Loan Documents or notice of any other fact which might increase
any Guarantor's risk hereunder; (v) notice of presentment,  demand, protest, and
notice of  dishonor  or  nonpayment  as to any  instrument;  (vi)  notice of any
acceleration  or other demand for payment of any of the Guaranteed  Obligations;
and (vii) all other notices and demands to which any Guarantor  might  otherwise
be  entitled  with  respect  to any of the  Guaranteed  Obligations  or the Loan
Documents or with respect to the  Guaranteed  Party's  enforcement of its rights
and remedies thereunder.  Each Guarantor further waives any right such Guarantor
may have,  by statute or  otherwise,  to require  the  Guaranteed  Party to seek
recourse first against the Borrower or any other person,  or to realize upon any
collateral for any of the Guaranteed  Obligations,  as a condition  precedent to
enforcing such Guarantor's  liability and obligations  under this Guaranty,  and
each Guarantor further waives any defense arising by reason of any incapacity or
other  disability  of the Borrower or by reason of any other  defense  which the
Borrower may have on any of the Guaranteed  Obligations or under any of the Loan
Documents. Each Guarantor consents and agrees that, without notice to or consent
by any  Guarantor  and without  affecting  or  impairing  the  liability  of any
Guarantor  under this Guaranty,  the Guaranteed  Party may compromise or settle,
extend  the  period  of  duration  or the time  for the  payment,  discharge  or
performance  of any of the  Guaranteed  Obligations  or Loan  Documents,  or may
refuse  to  enforce  or may  release  all or  any  parties  to any or all of the
Guaranteed   Obligations  (including  without  limitation  any  other  guarantor
thereof)  or any  collateral  therefor,  or may grant other  indulgences  to the
Borrower  or such  other  parties  in respect  thereof,  or may waive,  amend or
supplement  in any manner the  provisions  of any of the Loan  Documents  or any
other  document,  instrument  or  agreement  relating to or securing  any of the
Guaranteed  Obligations (other than this Guaranty),  or may release,  surrender,
exchange,  modify,  or  compromise  any and all  collateral  securing any of the
Guaranteed  Obligations or in which the Guaranteed  Party may at any time have a
lien,  or may  refuse  to  enforce  its  rights  or may make any  compromise  or
settlement or agreement therefor,  in respect of any and all of such collateral,
or with any party to any of the  Guaranteed  Obligations or Loan  Documents,  or
with any other person, or may release or substitute any one or more of the other
endorsers or guarantors of the Guaranteed  Obligations  whether  parties to this
Guaranty or not, or may exchange,  enforce,  waive or release any collateral for
any  guaranty  of any of the  Guaranteed  Obligations.  Each  Guarantor  further
consents and agrees that the Guaranteed  Party shall not be under any obligation
to marshal any assets in favor of such Guarantor or against or in payment of any
of the Guaranteed Obligations.

                6.  Subrogation and Other Rights.  Each Guarantor agrees that no
payment,   performance  or  enforcement  of  such  Guarantor's  liabilities  and
obligations  under this Guaranty shall cause such  Guarantor,  by subrogation or
otherwise,  to acquire any of the Guaranteed Party's rights against the Borrower
or any property of the  Borrower  (or any  interest in such  rights)  unless and
until the Guaranteed Party has received full and indefeasible  payment of all of
the Guaranteed Obligations.

                7.  Cross-Collateralization.  Each  Guarantor's  obligations and
liabilities to the Guaranteed  Party under this Guaranty shall be secured by (i)
any and all property pledged by
                                      -5-
<PAGE>
such  Guarantor  to the  Guaranteed  Party or in which the  Guaranteed  Party is
granted a Lien  pursuant  to the  Security  Agreement  or any  other  Collateral
Document  from  such  Guarantor  to the  Guaranteed  Party and any and all other
security interests,  security titles,  pledges,  collateral assignments or other
Liens which the Guaranteed  Party may now or hereafter have or acquire in, to or
on any real or personal  property assets of such Guarantor,  whether such assets
now exist or are hereafter acquired,  except to the extent that such Guarantor's
obligations and liabilities  hereunder are expressly  excluded from the coverage
of any such  Lien  under  the  express  terms of the  mortgage,  security  deed,
security agreement,  pledge agreement,  collateral  assignment or other document
which granted or grants such Lien.

                8. Guarantor Due Diligence and Benefit.  Each Guarantor is fully
aware of the financial condition, assets and prospects of the Borrower, and each
Guarantor is  executing  and  delivering  this  Guaranty  based solely upon such
Guarantor's  own  independent  investigation  thereof  and in no part  upon  any
representation,  warranty or statement of the  Guaranteed  Party with respect to
the Borrower's financial condition,  assets or prospects. Each Guarantor is in a
position to and hereby  assumes full  responsibility  for  obtaining any and all
information concerning the Borrower's financial condition,  assets and prospects
as such  Guarantor  may now or hereafter  deem  material to such its decision to
enter into and become  liable  under this  Guaranty  and such  Guarantor  is not
relying upon, nor does such Guarantor  expect the Guaranteed Party to furnish it
with any  information  which may be now or hereafter in the  Guaranteed  Party's
possession  concerning the Borrower's financial condition,  assets or prospects.
Each  Guarantor  hereby  knowingly  accepts the full range of risks  encompassed
within a contract  of  guaranty,  which  risks such  Guarantor  understands  may
include,  without  limitation,  the  possibility  that the  Borrower  may  incur
additional  indebtedness to the Guaranteed Party for which such Guarantor may be
liable hereunder after the Borrower's financial condition or means or ability to
pay its lawful debts when they fall due has deteriorated. Each Guarantor further
acknowledges and agrees that any credit or other financial accommodations now or
hereafter  extended  by the  Guaranteed  Party to the  Borrower  and any and all
forbearances  with respect to the  Borrower or its assets  which the  Guaranteed
Party may now or hereafter grant are and will be of direct interest, benefit and
advantage to such Guarantor.

                9.  Guaranteed  Party's  Accounts  and Records;  Application  of
Payments.  Each Guarantor agrees that, in the absence of manifest error, any and
all books and records relating to the Guaranteed  Obligations which are prepared
and maintained by the Guaranteed  Party shall constitute prima facie evidence of
the existence and amount of the  Guaranteed  Obligations.  In the event that the
Guaranteed  Party sends to the  Borrower  any  periodic or other  statements  of
account  with  respect to any or all of the  Guaranteed  Obligations,  each such
statement  rendered by the  Guaranteed  Party shall,  in the absence of manifest
error, be deemed final,  binding and conclusive  upon each Guarantor  unless the
Guaranteed  Party is notified by the Borrower in writing to the contrary  within
thirty (30) days after the date such statement was sent by the Guaranteed  Party
to the Borrower (and each such notice shall only be deemed an objection to those
items specifically  objected to therein).  Each Guarantor irrevocably waives the
right to direct the  application of any and all payments and  collections at any
time  hereafter  received  by the  Guaranteed  Party  from or on  behalf  of the
Borrower,
                                      -6-
<PAGE>
any Guarantor or otherwise with respect to any of the Guaranteed Obligations and
each Guarantor  does hereby  irrevocably  agree that the Guaranteed  Party shall
have the  continuing  exclusive  right to apply  and  re-apply  any and all such
payments and collections  received at any time hereafter by the Guaranteed Party
against the  Guaranteed  Obligations  in such manner and order as the Guaranteed
Party may deem advisable,  notwithstanding  any contrary entry by the Guaranteed
Party upon any of its books and records.

                10. Automatic  Acceleration of Guaranty.  Upon the occurrence of
any Event of  Default  described  in  Section  8.1(f),  (g) or (h) of the Credit
Agreement, all of the Guaranteed Obligations shall be deemed immediately due and
payable,  without notice or demand of any kind by the Guaranteed Party, and each
Guarantor  agrees  immediately  to  pay  the  Guaranteed  Obligations  in  full,
irrespective  of whether any or all of the  Guaranteed  Obligations  can then be
accelerated  against  the  Borrower  and  irrespective  of any  right  which the
Borrower  then  may have  under  any  bankruptcy,  receivership,  insolvency  or
moratorium law to cure defaults and reinstate the maturities of the Obligations.

                11.  Notices  to  Guarantors.  All  notices,  demands  and other
communications  hereunder  or  under  any of the  other  Loan  Documents  by the
Guaranteed  Party to any Guarantor  shall be effective (i) if given by telecopy,
when such  communication is transmitted to the telecopy number set forth beneath
such  Guarantor's  signature  below (with such  telecopy  promptly  confirmed by
delivery of a copy by personal  delivery or U.S.  mail as otherwise  provided in
this Section),  (ii) if given by mail within the United States of America, three
(3) days after such  communication  is deposited in the United  States mail with
first  class  postage  prepaid,  return  receipt  requested  addressed  to  such
Guarantor at its address set forth  beneath such  Guarantor's  signature  below,
(iii) if sent for  overnight  delivery  within the  United  States of America by
Federal Express or other reputable national overnight delivery service,  one (1)
Business Day after such communication is entrusted to such service for overnight
delivery and with recipient signature  required,  addressed as aforesaid or (iv)
if given by any other means,  when delivered at the address of the party to whom
such notice is being delivered.  Any Guarantor may designate a different address
or  telecopy  number  for such  Guarantor's  receipt  of such  notices  or other
communications  but no such  change  shall be  effective  unless  and  until the
Guaranteed Party actually receives written notice thereof from such Guarantor.

                12.  Collection  Costs.  Each  Guarantor  shall be liable to the
Guaranteed  Party for,  and shall pay to the  Guaranteed  Party on  demand,  all
reasonable costs (including  without limitation  reasonable  attorney's fees and
expenses)  incurred  by the  Guaranteed  Party in  enforcing  performance  of or
collecting any payments due under this Guaranty.

                13. Assignment and Transfer. This Guaranty shall be binding upon
each Guarantor and its  successors and permitted  assigns and shall inure to the
benefit of and be  enforceable  by the  Guaranteed  Party and its successors and
permitted  assigns.  Without limiting the generality of the preceding  sentence,
the Guaranteed  Party may assign or grant  participations  in all or any part of
the Guaranteed Obligations,  whereupon such assignee or participant shall become
entitled to all of the rights in respect thereof granted to the Guaranteed Party
herein.

<PAGE>
                14.  Governing  Law.  This  Guaranty  shall be  governed  by the
internal laws of the State of New York  (without  giving effect to its conflicts
of law rules).

                15.   Subordination  of  Borrower's  and  other  Credit  Party's
Obligations to the Guarantors. As an independent covenant, each Guarantor hereby
expressly  covenants and agrees for the benefit of the Guaranteed Party that all
present or future  indebtedness,  obligations and liabilities of the Borrower or
any other Credit Party (including without limitation any other Guarantor) to any
Guarantor of whatsoever description (collectively, the "Junior Claims") shall be
subordinate and junior in right of payment to all Obligations of the Borrower or
any such other Credit Party to the Guaranteed Party  (collectively,  the "Senior
Claims"),  effective upon the occurrence and during the  continuance of an Event
of Default under the Credit  Agreement.  If an Event of Default under the Credit
Agreement shall occur,  then,  unless and until such Event of Default shall have
been cured or shall have  ceased to exist,  no direct or  indirect  payment  (in
cash,  property,  securities,  by  set-off  or  otherwise)  shall be made by the
Borrower  or any other  Credit  Party to any  Guarantor  on account of or in any
manner in respect of any Junior Claim except such payments and distributions the
proceeds  of which  shall be  applied to the  Senior  Claims.  In the event of a
Proceeding (as  hereinafter  defined),  all Senior Claims shall first be paid in
full before any direct or indirect payment or distribution  (in cash,  property,
securities,  by set-off or otherwise)  shall be made to any Guarantor on account
of or in any manner in respect of any Junior  Claim  except  such  payments  and
distributions  the proceeds of which shall be applied to the Senior Claims.  For
the  purposes  of the  previous  sentence,  a  "Proceeding"  shall  occur if the
Borrower or any other Credit Party shall make an  assignment  for the benefit of
creditors, file a petition in bankruptcy, have entered against or in favor of it
an order  for  relief  under the  Bankruptcy  Code or  similar  law of any other
jurisdiction,  generally  fail to pay its debts as they come due  (either  as to
number or amount),  admit in writing its inability to pay its debts generally as
they mature, make a voluntary assignment for the benefit of creditors,  commence
any   proceeding   relating  to  it  under  any   reorganization,   arrangement,
readjustment  of  debt,  dissolution  or  liquidation  law  or  statute  of  any
jurisdiction,  whether now or hereafter in effect,  or by any act,  indicate its
consent  to,  approval  of or  acquiescence  in any  such  proceeding  or in the
appointment  of any  receiver  of, or trustee or  custodian  (as  defined in the
Bankruptcy  Code) for itself,  or any  substantial  part of its  property,  or a
trustee or a receiver  shall be  appointed  for the Borrower or any other Credit
Party or for a  substantial  part of the  property of the  Borrower or any other
Credit Party, or a petition under any bankruptcy,  reorganization,  arrangement,
readjustment  of  debt,  dissolution  or  liquidation  law  or  statute  or  any
jurisdiction  (whether now or hereafter  in effect)  shall be filed  against the
Borrower or any other Credit Party. In the event any direct or indirect  payment
or distribution is made to any Guarantor in contravention of this Section,  such
payment or distribution shall be deemed received in trust for the benefit of the
Guaranteed  Party and shall be immediately paid over to the Guaranteed Party for
application  against the Senior Claims.  Each  Guarantor  agrees to execute such
additional  documents as the Guaranteed Party may reasonably request to evidence
the subordination provided for in this Section.

                16.   Miscellaneous.   (a)  This  Guaranty  (together  with  any
collateral  documents  executed by any Guarantor to secure its  obligations  and
liabilities hereunder) constitutes the 
                                      -8-
<PAGE>
sole and entire  agreement  between the Guarantors and the Guaranteed Party with
respect to the subject  matter  hereof and  supersedes  and replaces any and all
prior agreements,  understandings,  negotiations or correspondence  between them
with respect thereto,  including  without  limitation any and all prior guaranty
agreements  executed  by any  Guarantor  in favor of the  Guaranteed  Party with
respect to any or all of the Guaranteed Obligations.

                (b) Time is of the essence of this Guaranty.

                (c) Words importing the singular number  hereunder shall include
the plural number and vice versa and any pronouns used herein shall be deemed to
cover all  genders.  The term  "person"  as used  herein  means any  individual,
corporation,  partnership,  joint  venture,  association,  joint-stock  company,
trust,  unincorporated  association,  or government  (or any agency or political
subdivision thereof).

                (d) Wherever  possible,  any provision in this Guaranty which is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be  ineffective  only to the  extent  of such  prohibition  or  unenforceability
without  invalidating the remaining  provisions hereof, and any such prohibition
or  unenforceability  in any one  jurisdiction  shall not  invalidate  or render
unenforceable such provision in any other jurisdiction.

                (e) No  amendment or waiver of any  provision of this  Guaranty,
nor consent to any departure by any Guarantor  therefrom,  shall be effective or
binding upon the Guaranteed  Party unless the Guaranteed  Party shall first have
given written consent thereto. Any such amendment, waiver or consent which is so
granted by the Guaranteed Party shall apply only to the specific  occasion which
is the subject of such  amendment,  waiver or consent and shall not apply to the
occurrence of the same or any similar event on any future  occasion.  No failure
on the part of the Guaranteed Party to exercise,  and no delay by the Guaranteed
Party in exercising,  any right hereunder shall operate as a waiver thereof, nor
shall any single or partial  exercise of any right hereunder  preclude any other
or further exercise thereof or the exercise of any other right by the Guaranteed
Party.  No notice to or demand on any  Guarantor  in any case by the  Guaranteed
Party  hereunder shall entitle such Guarantor to any further notice or demand in
any similar or other  circumstances  or constitute a waiver of the rights of the
Guaranteed Party to take any other or future action in any circumstances without
notice or demand. The remedies provided to the Guaranteed Party in this Guaranty
are cumulative and not exclusive of any other remedies provided by law.

                (f) This  Guaranty  may be executed in one or more  counterparts
and each such counterpart shall constitute an original and all such counterparts
together shall constitute one and the same instrument.

                (g) All Section headings herein are for convenience of reference
only and shall not limit or otherwise  affect the meaning or  interpretation  of
the provisions of this Guaranty.

                17. Jury Trial Waiver;  Consent to Jurisdiction and Venue.  EACH
GUARANTOR  HEREBY WAIVES ANY RIGHT SUCH  GUARANTOR MAY HAVE
                                      -9-
<PAGE>
UNDER ANY  APPLICABLE  LAW TO A TRIAL BY JURY WITH  RESPECT TO ANY SUIT OR LEGAL
ACTION WHICH MAY BE COMMENCED BY OR AGAINST ANY GUARANTOR,  THE GUARANTEED PARTY
OR  THE  BORROWER   CONCERNING  THE  INTERPRETATION,   CONSTRUCTION,   VALIDITY,
ENFORCEMENT OR PERFORMANCE OF THIS GUARANTY OR ANY OF THE LOAN DOCUMENTS. IN THE
EVENT ANY SUCH SUIT OR LEGAL ACTION IS COMMENCED BY THE GUARANTEED  PARTY,  EACH
GUARANTOR  HEREBY  EXPRESSLY  AGREES,  CONSENTS  AND  SUBMITS  TO  THE  PERSONAL
JURISDICTION  OF ANY STATE OR FEDERAL COURT SITTING IN THE CITY AND STATE OF NEW
YORK, BOROUGH OF MANHATTAN,  WITH RESPECT TO SUCH SUIT OR LEGAL ACTION, AND EACH
GUARANTOR  ALSO  EXPRESSLY  CONSENTS AND SUBMITS TO AND AGREES THAT VENUE IN ANY
SUCH SUIT OR LEGAL ACTION IS PROPER IN SAID COURTS AND COUNTY AND EACH GUARANTOR
HEREBY  EXPRESSLY  WAIVES ANY AND ALL PERSONAL RIGHTS UNDER APPLICABLE LAW OR IN
EQUITY TO OBJECT TO THE JURISDICTION AND VENUE OF SAID COURTS.  THE JURISDICTION
AND VENUE OF THE COURTS  CONSENTED  AND  SUBMITTED  TO AND  AGREED  UPON IN THIS
SECTION ARE NOT EXCLUSIVE BUT ARE CUMULATIVE AND IN ADDITION TO THE JURISDICTION
AND VENUE OF ANY OTHER COURT UNDER ANY APPLICABLE LAW OR IN EQUITY.

SECTION 15 OF THE FOREGOING
GUARANTY ACKNOWLEDGED AND
AGREED TO:

VODAVI COMMUNICATIONS
SYSTEMS, INC.


By: /s/ Greg Roeper
   ------------------------------------
Title: CFO and V.P.
      ---------------------------------
                                      -11-

                          TRADEMARK SECURITY AGREEMENT


                THIS  AGREEMENT  is made as of June  11,  1997,  by and  between
VODAVI COMMUNICATIONS  SYSTEMS, INC., an Arizona corporation formerly known as V
Technology  Acquisition  Corp.,  having a mailing  address at 8300 East Raintree
Drive,  Scottsdale,  Arizona  85260  ("Debtor"),  and GENERAL  ELECTRIC  CAPITAL
CORPORATION,  a New York  corporation  having a  mailing  address  at 350  South
Beverly Drive, Suite 200, Beverly Hills, California 90212 (the "Secured Party").

                               Statement of Facts
                               ------------------

                In connection with the financial  accommodations  to be extended
by the Secured Party to Debtor under the Amended and Restated Credit  Agreement,
dated as of April 11,  1994 as amended  and  restated  effective  as of June 11,
1997,  between  Debtor and Secured  Party (as the same may hereafter be amended,
restated,  supplemented  or otherwise  modified  from time to time,  the "Credit
Agreement"),  Debtor  has agreed to  collaterally  assign to the  Secured  Party
certain trademark rights in accordance with the terms of this Agreement.

                In  consideration  of the foregoing  premises and other good and
valuable consideration, Debtor hereby agrees with the Secured Party as follows:

                               Statement of Terms
                               ------------------

                Grant of Security  Interest.  To secure the  complete and timely
satisfaction of all of Debtor's obligations hereunder,  as well as to secure all
of the rights of the  Secured  Party  hereunder,  and to secure the  payment and
performance  of any and all  Obligations  (as such term is defined in the Credit
Agreement) (all such Obligations being herein  collectively  called the "Secured
Obligations"),  Debtor  hereby  grants  to  the  Secured  Party  a  present  and
continuing  security interest in the entire right,  title and interest of Debtor
in and to the trademark  application(s)  and  trademark(s)  listed on Schedule 1
attached hereto together with all goodwill of Debtor's business relating thereto
and all other assets of Debtor  necessary to produce the products for which such
applications will be or such trademarks are used,  including without  limitation
all proceeds thereof (such as, by way of example, license royalties and proceeds
of  infringement  suits),  the  right  to  sue  for  past,  present  and  future
infringements,  all rights  corresponding  thereto  throughout the world and all
renewals,  extensions  and  other  proceeds  thereof  (collectively  called  the
"Trademarks").

                Representations  and Warranties.  Debtor represents and warrants
that:

                The Trademarks are subsisting and have not been adjudged invalid
or unenforceable, in whole or in part;

                To the best of Debtor's  knowledge,  each of the  Trademarks  is
valid and enforceable;
<PAGE>
                Debtor  is the  sole  and  exclusive  owner  of the  entire  and
unencumbered  right,  title and interest in and to each of the Trademarks,  free
and clear of any liens,  charges and encumbrances,  including without limitation
licenses  and  covenants  by Debtor  not to sue third  persons,  except  for any
Permitted Exceptions (as such term is defined in the Credit Agreement); and

                Debtor has the  unqualified  right to enter into this  Agreement
and perform its terms.

                No  Inconsistent  Licenses.  Debtor agrees that, so long as this
Agreement is in effect,  it will not enter into any agreement  (for  example,  a
license or assignment agreement) which is inconsistent with Debtor's obligations
under this Agreement, without the Secured Party's prior written consent.

                Event of  Default.  The  failure of the Debtor to perform any of
its  obligations   hereunder,   any  breach  in  any  material  respect  of  any
representation  or warranty of the Debtor herein, or the occurrence of any Event
of Default under (and as such term is defined in) the Credit Agreement will also
constitute a default by Debtor under this  Agreement  (herein  referred to as an
"Event of Default").

                Remedies on Default. If any Event of Default shall have occurred
and be continuing, the Secured Party shall have, in addition to all other rights
and remedies given it by this Agreement, those allowed by law and the rights and
remedies  of a secured  party  under the Code (as such  term is  defined  in the
Credit  Agreement) and,  without  limiting the generality of the foregoing,  the
Secured Party may  immediately,  without demand of performance and without other
notice or demand  whatsoever  to  Debtor,  sell at  public  or  private  sale or
otherwise  realize  upon,  the  whole  or  from  time to  time  any  part of the
Trademarks,  or any  interest  which the  Debtor  may have  therein  and,  after
deducting  from the proceeds of sale or other  disposition of the Trademarks all
expenses (including all reasonable expenses for legal services actually incurred
without giving effect to any statutory presumption),  shall apply the residue of
such proceeds toward the payment of the Secured  Obligations  (which application
shall  be made,  first,  to the  Secured  Party's  costs  and  expenses  of such
collection,  sale or other  disposition,  including  reasonable  attorney's fees
actually incurred without giving effect to any statutory  presumption,  and then
to the  payment of the other  Secured  Obligations  then due).  Debtor  shall be
liable for any deficiency remaining after the application of such proceeds.  Any
remainder of the proceeds after payment in full of the Secured Obligations shall
be paid over to the Debtor. If required by applicable law, notice of any sale or
other  disposition of the Trademarks  shall be given to Debtor at least ten (10)
days before the time of any intended public or private sale or other disposition
of the Trademarks is to be made,  which Debtor hereby agrees shall be reasonable
notice of such sale or other disposition.  At any such sale or other disposition
the Secured Party may, to the extent  permissible under applicable law, purchase
the whole or any part of the Trademarks  sold, free from any right of redemption
on the part of Debtor, which right is hereby waived and released.
                                       -2-
<PAGE>
                No Waiver.  No course of dealing  between Debtor and the Secured
Party, nor any failure to exercise, nor any delay in exercising,  on the part of
the Secured Party,  any right,  power or privilege  hereunder shall operate as a
waiver thereof;  nor shall any single or partial exercise of any right, power or
privilege  hereunder  preclude  any other or  further  exercise  thereof  or the
exercise of any other right, power or privilege.

                Severability.  The provisions of this Agreement are several, and
if any clause or provision shall be held invalid and  unenforceable  in whole or
in part in any  jurisdiction,  then such  invalidity or  unenforceability  shall
affect only such clause or provision, or part thereof, in such jurisdiction, and
shall  not  in  any  manner  affect  such  clause  or  provision  in  any  other
jurisdiction,  or any  other  clause  or  provision  of  this  Agreement  in any
jurisdiction.

                Modification.  This Agreement is subject to modification only by
a writing signed by the Debtor and the Secured Party.

                Benefit of Agreement. The benefits and burdens of this Agreement
shall inure to the benefit of and be binding upon the  respective  heirs,  legal
representatives, successors and assigns of the parties.

                Governing Law. The validity and interpretation of this Agreement
and the rights and  obligations  of the parties shall be governed by the laws of
the State of New York  (without  giving effect to its conflict of law rules) and
the United States of America.

                Terminology;  Headings.  All  singular  terms used herein  shall
include the plural and vice versa,  and all pronouns used herein shall be deemed
to cover all genders.  All section  headings used herein are for  convenience of
reference only and do not constitute a substantive part of this Agreement.

                Execution in Counterparts. This Agreement may be executed in any
number  of  counterparts,  each  of  which  counterparts  when so  executed  and
delivered,  shall be deemed to be an  original,  and all of which  counterparts,
taken together, shall constitute one and the same Agreement.

                Expenses;  Indemnity. Debtor will upon demand pay to the Secured
Party the amount of any and all expenses,  including reasonable  attorney's fees
and fees of  other  experts,  which  the  Secured  Party  may from  time to time
actually  incur  (and   calculated   without  giving  effect  to  any  statutory
presumption) in connection with (i) the  administration of this Agreement,  (ii)
the  preservation  of or the sale or other  disposition of or other  realization
upon any of the  Trademarks,  (iii) the  exercise or  enforcement  of any of the
rights of the  Secured  Party  hereunder  or (iv) the  failure  by the Debtor to
perform or observe any of the  provisions  hereof.  Debtor also hereby agrees to
indemnify the Secured Party and hold the Secured Party harmless from and against
any  liability,  loss,  damage,  suit,  action or  proceeding  ever  suffered or
incurred by the Secured  Party as a result of (i)  Debtor's  failure to observe,
                                      -3-
<PAGE>
perform or  discharge  Debtor's  duties  hereunder  or (ii) the Secured  Party's
holding or administering this Agreement or its rights,titles or interests in the
Trademarks,  unless  with  respect to any of the  above,  the  Secured  Party is
determined  to have  acted with gross  negligence  or to have  engaged in wilful
misconduct.  The obligations of the Debtor under this paragraph 14 shall survive
the termination of this Agreement.

                Security Agreement;  Intercreditor Agreement,  Entire Agreement;
Termination.  (a) The Secured Party also has a Lien in the Trademarks  under the
terms of the Security Agreement, dated April 11, 1994, executed by the Debtor in
favor of the Secured Party (the  "Security  Agreement"),  and this  Agreement is
intended  to  supplement  such  Security  Agreement,  but  in the  event  of any
inconsistency  between the terms of this  Agreement  and those of such  Security
Agreement,  the terms of such Security Agreement shall control,  and the Secured
Party may elect to pursue its rights and remedies with respect to the Trademarks
under either or both of this Agreement or such Security Agreement.

                (b)  This  Agreement,   together  with  all  other  instruments,
agreements and  certificates  executed by the parties in connection  herewith or
with reference hereto,  embodies the entire  understanding and agreement between
the parties  hereto with respect to the subject matter hereof and supersedes all
prior agreements,  understandings  and inducements,  whether express or implied,
oral or written.

                (c) This Agreement  shall terminate with, and in accordance with
the terms of, the Security  Agreement,  and all of the Secured Party's  security
interests hereunder shall be automatically  terminated and released on such date
(subject to reinstatement as provided in Section 11 of the Security Agreement).

written.

                          TRADEMARK SECURITY AGREEMENT


                THIS  AGREEMENT  is made as of June  11,  1997,  by and  between
ENHANCED SYSTEMS,  INC., an Arizona corporation having a mailing address at 8300
East Raintree Drive, Scottsdale,  Arizona 85260 ("Debtor"), and GENERAL ELECTRIC
CAPITAL  CORPORATION,  a New York  corporation  having a mailing  address at 350
South Beverly Drive,  Suite 200,  Beverly Hills,  California 90212 (the "Secured
Party").

                               Statement of Facts
                               ------------------

                In connection with the financial  accommodations  to be extended
by the Secured Party to Vodavi  Communications  Systems,  Inc. (the  "Borrower")
under the Amended and Restated Credit  Agreement,  dated as of April 11, 1994 as
amended and restated  effective  as of June 11,  1997,  between the Borrower and
Secured Party (as the same may hereafter be amended,  restated,  supplemented or
otherwise modified from time to time, the "Credit Agreement"), Debtor has agreed
to  collaterally  assign  to the  Secured  Party  certain  trademark  rights  in
accordance with the terms of this Agreement.

                In  consideration  of the foregoing  premises and other good and
valuable consideration, Debtor hereby agrees with the Secured Party as follows:

                               Statement of Terms
                               ------------------

                Grant of Security  Interest.  To secure the  complete and timely
satisfaction of all of Debtor's obligations hereunder,  as well as to secure all
of the rights of the  Secured  Party  hereunder,  and to secure the  payment and
performance  of any and all  Obligations  (as such term is defined in the Credit
Agreement)  including  Debtor's  guarantee  thereof (all such Obligations  being
herein collectively called the "Secured  Obligations"),  Debtor hereby grants to
the  Secured  Party a present  and  continuing  security  interest in the entire
right,  title and interest of Debtor in and to the trademark  application(s) and
trademark(s)  listed on Schedule 1 attached hereto together with all goodwill of
Debtor's  business  relating thereto and all other assets of Debtor necessary to
produce the products for which such  applications will be or such trademarks are
used,  including  without  limitation  all proceeds  thereof (such as, by way of
example, license royalties and proceeds of infringement suits), the right to sue
for past, present and future  infringements,  all rights  corresponding  thereto
throughout the world and all renewals,  extensions  and other  proceeds  thereof
(collectively called the "Trademarks").

                Representations  and Warranties.  Debtor represents and warrants
that:

                The Trademarks are subsisting and have not been adjudged invalid
or unenforceable, in whole or in part;

                To the best of Debtor's  knowledge,  each of the  Trademarks  is
valid and
<PAGE>
enforceable;

                Debtor  is the  sole  and  exclusive  owner  of the  entire  and
unencumbered  right,  title and interest in and to each of the Trademarks,  free
and clear of any liens,  charges and encumbrances,  including without limitation
licenses  and  covenants  by Debtor  not to sue third  persons,  except  for any
Permitted Exceptions (as such term is defined in the Credit Agreement); and

                Debtor has the  unqualified  right to enter into this  Agreement
and perform its terms.

                No  Inconsistent  Licenses.  Debtor agrees that, so long as this
Agreement is in effect,  it will not enter into any agreement  (for  example,  a
license or assignment agreement) which is inconsistent with Debtor's obligations
under this Agreement, without the Secured Party's prior written consent.

                Event of  Default.  The  failure of the Debtor to perform any of
its  obligations   hereunder,   any  breach  in  any  material  respect  of  any
representation  or warranty of the Debtor herein, or the occurrence of any Event
of Default under (and as such term is defined in) the Credit Agreement will also
constitute a default by Debtor under this  Agreement  (herein  referred to as an
"Event of Default").

                Remedies on Default. If any Event of Default shall have occurred
and be continuing, the Secured Party shall have, in addition to all other rights
and remedies given it by this Agreement, those allowed by law and the rights and
remedies  of a secured  party  under the Code (as such  term is  defined  in the
Credit  Agreement) and,  without  limiting the generality of the foregoing,  the
Secured Party may  immediately,  without demand of performance and without other
notice or demand  whatsoever  to  Debtor,  sell at  public  or  private  sale or
otherwise  realize  upon,  the  whole  or  from  time to  time  any  part of the
Trademarks,  or any  interest  which the  Debtor  may have  therein  and,  after
deducting  from the proceeds of sale or other  disposition of the Trademarks all
expenses (including all reasonable expenses for legal services actually incurred
without giving effect to any statutory presumption),  shall apply the residue of
such proceeds toward the payment of the Secured  Obligations  (which application
shall  be made,  first,  to the  Secured  Party's  costs  and  expenses  of such
collection,  sale or other  disposition,  including  reasonable  attorney's fees
actually incurred without giving effect to any statutory  presumption,  and then
to the  payment of the other  Secured  Obligations  then due).  Debtor  shall be
liable for any deficiency remaining after the application of such proceeds.  Any
remainder of the proceeds after payment in full of the Secured Obligations shall
be paid over to the Debtor. If required by applicable law, notice of any sale or
other  disposition of the Trademarks  shall be given to Debtor at least ten (10)
days before the time of any intended public or private sale or other disposition
of the Trademarks is to be made,  which Debtor hereby agrees shall be reasonable
notice of such sale or other disposition.  At any such sale or other disposition
the Secured Party may, to the extent  permissible under applicable law, purchase
the whole or any part of the Trademarks  sold, free 
                                      -2-
<PAGE>
from any right of redemption on the part of Debtor, which right is hereby waived
and released.
                                      
                No Waiver.  No course of dealing  between Debtor and the Secured
Party, nor any failure to exercise, nor any delay in exercising,  on the part of
the Secured Party,  any right,  power or privilege  hereunder shall operate as a
waiver thereof;  nor shall any single or partial exercise of any right, power or
privilege  hereunder  preclude  any other or  further  exercise  thereof  or the
exercise of any other right, power or privilege.

                Severability.  The provisions of this Agreement are several, and
if any clause or provision shall be held invalid and  unenforceable  in whole or
in part in any  jurisdiction,  then such  invalidity or  unenforceability  shall
affect only such clause or provision, or part thereof, in such jurisdiction, and
shall  not  in  any  manner  affect  such  clause  or  provision  in  any  other
jurisdiction,  or any  other  clause  or  provision  of  this  Agreement  in any
jurisdiction.

                Modification.  This Agreement is subject to modification only by
a writing signed by the Debtor and the Secured Party.

                Benefit of Agreement. The benefits and burdens of this Agreement
shall inure to the benefit of and be binding upon the  respective  heirs,  legal
representatives, successors and assigns of the parties.

                Governing Law. The validity and interpretation of this Agreement
and the rights and  obligations  of the parties shall be governed by the laws of
the State of New York  (without  giving effect to its conflict of law rules) and
the United States of America.

                Terminology;  Headings.  All  singular  terms used herein  shall
include the plural and vice versa,  and all pronouns used herein shall be deemed
to cover all genders.  All section  headings used herein are for  convenience of
reference only and do not constitute a substantive part of this Agreement.

                Execution in Counterparts. This Agreement may be executed in any
number  of  counterparts,  each  of  which  counterparts  when so  executed  and
delivered,  shall be deemed to be an  original,  and all of which  counterparts,
taken together, shall constitute one and the same Agreement.

                Expenses;  Indemnity. Debtor will upon demand pay to the Secured
Party the amount of any and all expenses,  including reasonable  attorney's fees
and fees of  other  experts,  which  the  Secured  Party  may from  time to time
actually  incur  (and   calculated   without  giving  effect  to  any  statutory
presumption) in connection with (i) the  administration of this Agreement,  (ii)
the  preservation  of or the sale or other  disposition of or other  realization
upon any of the  Trademarks,  (iii) the  exercise or  enforcement  of any of the
rights of the  Secured  Party  hereunder  or (iv) the  failure  by the Debtor to
perform or observe any of 
                                      -3-
<PAGE>
the provisions hereof.  Debtor also hereby agrees to indemnify the Secured Party
and hold the  Secured  Party  harmless  from and against  any  liability,  loss,
damage,  suit,  action or  proceeding  ever  suffered or incurred by the Secured
Party as a result of (i)  Debtor's  failure to  observe,  perform  or  discharge
Debtor's duties  hereunder or (ii) the Secured Party's holding or  administering
this Agreement or its rights, titles or interests in the Trademarks, unless with
respect to any of the above,  the Secured Party is determined to have acted with
gross negligence or to have engaged in wilful misconduct. The obligations of the
Debtor under this paragraph 14 shall survive the termination of this Agreement.

                Security Agreement;  Intercreditor Agreement,  Entire Agreement;
Termination.  (a) The Secured Party also has a Lien in the Trademarks  under the
terms of the  Security  Agreement,  dated as of June 11,  1997,  executed by the
Debtor  in favor of the  Secured  Party  (the  "Security  Agreement"),  and this
Agreement is intended to supplement such Security Agreement, but in the event of
any inconsistency between the terms of this Agreement and those of such Security
Agreement,  the terms of such Security Agreement shall control,  and the Secured
Party may elect to pursue its rights and remedies with respect to the Trademarks
under either or both of this Agreement or such Security Agreement.

                (b)  This  Agreement,   together  with  all  other  instruments,
agreements and  certificates  executed by the parties in connection  herewith or
with reference hereto,  embodies the entire  understanding and agreement between
the parties  hereto with respect to the subject matter hereof and supersedes all
prior agreements,  understandings  and inducements,  whether express or implied,
oral or written.

                (c) This Agreement  shall terminate with, and in accordance with
the terms of, the Security  Agreement,  and all of the Secured Party's  security
interests hereunder shall be automatically  terminated and released on such date
(subject to reinstatement as provided in Section 11 of the Security Agreement).

                          STRATEGIC ALLIANCE AGREEMENT
                          ----------------------------


                  THIS STRATEGIC  ALLIANCE  AGREEMENT (this "Agreement") is made
and entered  into as of the 22nd day of May,  1997,  effective as of May 1, 1997
(the "Effective Date") by and between VODAVI  COMMUNICATIONS  SYSTEMS,  INC., an
Arizona  corporation  located at 8300 East Raintree Drive,  Scottsdale,  Arizona
85260  ("Vodavi"),  and PARADYGM  COMMUNICATIONS  INC.,  a Delaware  corporation
located at 2100 Parklake Drive NE, Atlanta, Georgia 30345 ("Paradigm").

                                    RECITALS:

                  A.   Vodavi  is  engaged  in  the   business   of   designing,
manufacturing and supplying telecommunications products,  including, among other
things,  (i) a Vodavi  Digital  PBX  telephone  system  containing,  among other
things,  keysets,  D.S.S.  and  specialized  software  developed  by Vodavi (the
"Software")   enabling  its   specialized   use  primarily  in  the  hotel/motel
(hospitality)  service  industry,  extended  health  care  facilities  and other
similar  businesses (the  "Industries")  (the PBX system containing the Software
may  hereinafter be referred to as the "PBX Systems"),  (ii) feature  telephones
("2600  Series   Telephones"),   (iii)  single-line   telephones  ("2500  Series
Telephones"),  and (iv) voice-mail/auto  attendant systems ("Voice Systems") all
as are  described  in  Exhibit  A as the same may be  amended  from time to time
(collectively, the "Products").

                  B. Upon the terms and conditions set forth in this  Agreement:
(i)  Paradigm  desires to purchase and become a  distributor  of the Products in
North America, (ii) Paradigm desires to exclusively engage Vodavi to manufacture
and supply  Paradigm with its  requirements  of the  Products;  and (iii) Vodavi
desires to sell the Products to Paradigm.

                                   AGREEMENT:

                  NOW, THEREFORE,  for valuable  consideration,  the receipt and
sufficiency  of which are  hereby  acknowledged,  Vodavi and  Paradigm  agree as
follows:

                  1.  Appointment of Vodavi.  Subject to and in accordance  with
the terms and  conditions of this  Agreement,  Paradigm  appoints  Vodavi as the
exclusive manufacturer of all of Paradigm's requirements of the Products. Vodavi
hereby accepts such  appointment.  Paradigm  agrees to purchase the Products and
all similar  telecommunication  products for the Industries in the Territory (as
hereinafter  defined)  only  from  Vodavi  during  the Term of  Exclusivity  (as
hereinafter defined).

                  2. Appointment of Paradigm.  Subject to and in accordance with
the terms and  conditions of this  Agreement,  Vodavi  appoints  Paradigm as the
exclusive distributor of the PBX Systems and the software contained in the Voice
Systems, and a non-exclusive distributor
<PAGE>
of the other  Products,  in the Territory  until December 31, 1998 (the "Term of
Exclusivity").  Paradigm hereby accepts such appointment.  Paradigm shall remain
the exclusive  distributor of the PBX Systems and the software  contained in the
Voice Systems in the Territory,  and the Term of Exclusivity  shall be extended,
from year to year thereafter  during the term of this  Agreement,  provided that
Paradigm  satisfies its Minimum Purchase  Obligations (as defined in Section 14)
for the  previous  year.  If Paradigm  does not  satisfy  its  Minimum  Purchase
Obligation  during any year of the term of this  Agreement,  then, at the end of
that year, and at the option of Vodavi,  (i) the Term of Exclusivity  shall end,
(ii) Paradigm  shall become a  non-exclusive  distributor of the PBX Systems and
the  software   contained  in  the  Voice  Systems  in  the  Territory,   and  a
non-exclusive licensee of the Software, and (iii) Vodavi shall have the right to
appoint other  distributors of the PBX Systems and the software contained in the
Voice Systems in the Territory.

                  3.  Territory.  The "Territory" for purposes of this Agreement
shall mean North  America,  including  Canada and the United  States of America,
Puerto  Rico,  Guam,  the U.S.  Virgin  Islands and to the extent  permitted  by
Vodavi's manufacturing partner, Mexico. The parties hereto may revise and update
the  Territory  at any  time or from  time to time by an  amendment  in  writing
attached to this Agreement.

                  4. Term.  The term of this  Agreement  shall  commence  on the
Effective  Date and  continue in effect until  December  31, 2001 (the  "Initial
Term").  Following the expiration of the Initial Term,  this Agreement  shall be
automatically renewed for successive three-year terms each individually referred
to as a "Renewal  Term," unless either party notifies the other party in writing
of its desire not to renew no later than one hundred  eighty (180) days prior to
the expiration of the Initial Term or any Renewal Term, as applicable, whereupon
this Agreement  shall  terminate at the end of the term within which such notice
is given.

                  5. Pricing by Vodavi;  Payments.  The  purchase  price for the
Products  shall be set forth on Exhibit B as may be amended from time to time by
written  notice from Vodavi to Paradigm of a price  change at least  ninety (90)
days prior to the effective date of the price change.  Vodavi shall not increase
any prices prior to December 31, 1998,  unless  necessitated  by a force majeure
described in Section 23 hereof; provided, however, that Vodavi provides Paradigm
with  proof of the  applicable  cost  increases  to  Vodavi  caused by the force
majeure and provided further that the price increase does not exceed ten percent
(10%)  of the  applicable  purchase  price  prior  to the  increase.  Except  as
otherwise  expressly  agreed in writing by the parties  hereto,  payment for the
Products shall be made in United States  dollars in an amount  adequate to cover
the full purchase price plus all other charges,  if any,  incurred by Vodavi for
the account of Paradigm.  All payments for Products  shall be due and payable in
full within  thirty  (30) days from the date of  invoice.  In no event shall the
invoice date precede (a) the shipping  date of the Products for which payment is
due for Products Vodavi is not  warehousing;  or (b) the date of delivery of the
Products to Vodavi's warehouse for Products Vodavi is warehousing.
                                        2
<PAGE>
                  All  payments  due  shall  at  all  times  be  secured  by  an
irrevocable  standby  letter of credit  (the  "Letter of  Credit")  obtained  by
Paradigm  and  submitted  to  Vodavi,  in a form and from a banking  institution
acceptable to Vodavi.  The Letter of Credit shall be in an amount equal to or in
excess of all  outstanding  invoices  due from  Paradigm to Vodavi plus  payment
amounts for Products  ordered by  Paradigm.  Upon  execution of this  Agreement,
Paradigm shall provide the Letter of Credit to Vodavi, which will have a one (1)
year term and shall be  renewable  annually  or from time to time as required by
this  Agreement.  If full  payment of any invoice is not received by Vodavi when
due,  then  Paradigm's  account  will be deemed  delinquent  and Vodavi shall be
entitled to draw down from the Letter of Credit the amount  delinquent  together
with a late  payment fee of one percent  (1%) of the balance due for each month,
or any part thereof, that any amount remains (or remained) delinquent.  The late
payment fee permits Vodavi to be compensated for receiving a late payment and is
not  intended  to  create a credit  arrangement.  Vodavi  reserves  the right to
suspend performance,  to decline to deliver except for cash in advance and/or to
stop delivery of Products in transit whenever Paradigm's account is delinquent.

                  6.  Private-Label  Products.  The PBX System  keysets  and, at
Paradigm's  request,  2600 Series Telephones  (collectively,  the "Private Label
Products")  shall  be  manufactured   using  Paradigm's,   or  another  mutually
agreeable, name and logo. Prior to tooling Vodavi's equipment for the production
of the  Private  Label  Products,  Paradigm  shall  furnish to Vodavi all molds,
stamps,  artwork, and other specialized  materials and instructions  required to
accurately  place the name and logo on the Private  Label  Products.  All molds,
stamps,  artwork and other  specialized  materials  not provided by Paradigm but
required to label the Private Label  Products as instructed by Paradigm shall be
acquired and/or commissioned by Vodavi at the sole cost and expense of Paradigm,
and  Paradigm  agrees to promptly pay all such costs and  expenses.  The Private
Label  Products  may also bear the name and logo of Vodavi on the outside  metal
base and anywhere on the interior components of the Private Label Products.  The
PBX Systems and other Products may bear the trade marks, name and logo of Vodavi
and Paradigm.

                  7.  Warehousing;  Inventory  Fulfillment;  Technical  Support.
Commencing on the  Effective  Date and  continuing  until ninety (90) days after
Vodavi  receives  written  notice to cease  warehousing  Products,  Vodavi shall
perform,  for  and  on  behalf  of  Paradigm,   the  warehousing  and  inventory
fulfillment  functions  described  and at the costs set  forth,  on  Exhibit  C.
Exhibit C also sets forth the costs any  payment  terms for the  performance  of
warehousing  and  inventory  fulfillment.  Paradigm  shall pay all such costs to
Vodavi as and when due.

                  Commencing on the Effective Date and  continuing  until ninety
(90) days after Vodavi  receives  written  notice to cease  providing  technical
support, Vodavi shall perform, for and on behalf of Paradigm,  technical support
for the  Products as described on Exhibit D. Exhibit D also sets forth the costs
of any payment terms for the  performance of technical  support.  Paradigm shall
pay all such costs to Vodavi as and when due.
                                        3
<PAGE>
                  8. Ordering Procedures. All orders of the Products pursuant to
this  Agreement  shall be subject to the terms and  conditions set forth in this
Agreement,  notwithstanding  the terms specified in any purchase order,  and the
terms and conditions of this Agreement shall supersede all pre-printed terms and
conditions of any such purchase order,  unless otherwise agreed to in writing by
Vodavi.  Whenever  Paradigm desires to purchase any of the Products from Vodavi,
Paradigm  shall deliver to Vodavi a numbered and signed  written  purchase order
specifying  the  quantities  and model  numbers  of the  Products  desired to be
purchased  and the  desired  destination  and  shipping  date  for  the  ordered
Products, which shipping date must take into account an appropriate lead time to
manufacture such Products.  All purchase orders shall be made for Products in at
least the minimum  quantities  set forth in Exhibit E attached  hereto as may be

Private Label  Products)  shall be shipped within  forty-eight  (48) hours after
receipt  by Vodavi  to the  extent  such  Products  are  available  in  Vodavi's
warehouse.  Vodavi  shall  use its  best  reasonable  efforts  to  stock  in its
warehouse sufficient quantities of such telephones to meet Paradigm's Forecasts,
as set forth in  Section  14; in all  events  however,  orders  for such will be
shipped within one hundred twenty (120) days. All orders for Voicemail  shall be
shipped within ten (10) days after receipt by Vodavi.  The appropriate lead time

without limitation,  freight, insurance,  customs, duties, demurrage charges and
turnover,  sales, excise and other foreign, federal, state or local taxes, shall
be borne by Paradigm or, if paid or incurred by Vodavi,  shall be  reimbursed by

responsibility  of Paradigm,  and Paradigm  shall promptly pay all such charges.
Vodavi shall use a freight carrier of its own choice, unless Paradigm designates
an alternative freight carrier for delivery of Products,  whereupon Vodavi shall
use Paradigm's  designated  freight  carrier for shipments of Products  whenever
possible.

                  10. Risk of Loss.  Paradigm shall bear the entire risk of loss
of or damage to Products occurring at any time after delivery of the Products to
the freight carrier to the extent Vodavi is not warehousing the Products, and at
any  time  after  delivery  to  Vodavi's  warehouse  to  the  extent  Vodavi  is
warehousing  the Products.  If Vodavi delays delivery of Products to the freight
carrier due to any action or request of Paradigm,  then  Paradigm  shall pay all
reasonable  storage and insurance  charges incurred by Vodavi for such Products.
If any of the Products are returned by Paradigm,  risk of loss shall remain upon
Paradigm until the Products are received by Vodavi. Paradigm agrees to indemnify
and hold Vodavi  harmless for, from and against any and all loss of or damage to
the Products  sustained while risk of loss remains upon Paradigm.  Vodavi agrees
to indemnify and hold  Paradigm  harmless for, from and against any and all loss
of or damage to the Products sustained while risk of loss remains upon Vodavi.

                  11. PBX Software  License Grant.  Paradigm  acknowledges  that
Vodavi has  developed  certain  software  for use only in the PBX  Systems  that
enables the PBX Systems to be used  primarily in the  hotel/motel  (hospitality)
service  industry and may be adapted to the other  Industries (the  "Software").
Subject to Paradigm's adherence to the terms of this Agreement, Vodavi grants to
Paradigm for the Term of Exclusivity a non-exclusive license to use the Software
and to  sublicense  use of the  Software by  Paradigm's  customers,  but only as
incorporated  into a PBX System  manufactured  by Vodavi and used in  connection
with the  Industries in the  Territory.  This  Agreement  transfers no rights to
Paradigm or any of  Paradigm's  customers  with respect to all or any portion of
the  Software  except  as  specifically  provided  herein.  Paradigm  is  hereby
prohibited from reverse engineering (by disassembly, decompilation or otherwise)
the Software  and may not copy or  reproduce  all or any portion of the Software
for any purpose whatsoever.  Notwithstanding anything in this Agreement,  Vodavi
retains  all title to,  and,  except as  expressly  and  unambiguously  licensed
herein, all rights to the Software,  all copies and derivative works thereof (by
whomever  produced) and all related  documentation and materials.  Paradigm will
cooperate  with Vodavi in  preventing  infringement  of the  Software and assist
Vodavi in all reasonable respects to protect its rights in and to the Software.

                  14. Forecasts;  Minimum Purchase Obligation.  On or before the
tenth  (10th)  business day of each  calendar  month,  Paradigm  will provide to
Vodavi a written  report  containing  sales and  customer  data for the previous
month  and a  forecast  of  its  Product  delivery  requirements  for  the  next
consecutive  eleven  (11)  calendar  month  period (a  "Forecast").  The initial
Forecast will indicate  scheduled  shipment for the first four (4) months of the
Initial Term for Private Label  telephones  and for the first five (5) months of
the  Initial  Term for all other  Products,  and  forecasted  deliveries  of all
Products for the six (6) months  subsequent  to the first five (5) months of the
Initial  Term.  The first (5) five  months  (four (4) months for  Private  Label

such purchase commitments.  The rolling Forecast submitted each month shall take
into account the firm purchase  commitments  from the preceding  month's rolling
Forecast. On an annual basis, the total of the purchases of Products by Paradigm
from Vodavi,  shall be at least in those minimum  annual  dollar  amounts as set
forth on Exhibit F attached hereto ("Minimum Purchase Obligations").  During the
course of the Initial Term, Paradigm shall order at least the minimum quantities
of  certain  of the  Products  as is set  forth in  Exhibit  F  attached  hereto
("Minimum Unit Obligation"). The parties hereto shall update and amend Exhibit F
from time to time as new  Products are added to Exhibit A attached  hereto,  new
areas of Territory  are added and within one hundred  eighty (180) days prior to
any Renewal Term. To the extent Vodavi 
                                        6
<PAGE>
does not timely deliver Products, recalls Products,  delivers defective Products
or in the event of a force  majeure,  as  discussed  in Section  24, the Minimum
Purchase  Obligations and Minimum Unit Obligations shall be reasonably  adjusted
accordingly.

                  15. Other Obligations of Paradigm.  Paradigm agrees to use its
best efforts  throughout the term of this Agreement to encourage and develop the
full sales potential for the Products in the Industries in the Territory, and to
promptly meet all demands and needs for marketing and after-sale  support of the
Products  sold  by  Paradigm.  Paradigm  shall  endeavor  to  maintain  adequate
inventories of the Products at all times,  and shall  encourage  purchase of the
Products by Paradigm's  existing customer base. Except as set forth in Section 7
hereof, Paradigm shall be responsible for all costs and expenses associated with
the  installation  of the Products,  after-sale  service,  customer  support and
training of the end-users of the Products.

                  16.  Other  Obligations  of Vodavi.  Vodavi  agrees to use its
reasonable  best  efforts  throughout  the  term of this  Agreement  to  support
Paradigm  in its  efforts  to  promote  the sale of the  Products  by  providing
reasonable  technical and sales training assistance for Paradigm's employees and
sales  representatives  in the  Paradigm  sales  organization,  as set  forth in
Attachments D and E to Exhibit G attached hereto.

                  17. Acceptance and Inspection.  To the extent that Vodavi does
not  warehouse the  Products,  Paradigm  shall have a period of thirty (30) days
following  the  delivery of a shipment of Products  from Vodavi to inspect  that
shipment for defects and nonconformities.  Failure to notify Vodavi, in writing,
of a rejection of any Products  received within the thirty (30) day period,  for
reason of defect  and/or  nonconformity,  shall be deemed an  acceptance  of the
entire  shipment by Paradigm.  Paradigm's  acceptance  of Products  shall not be
deemed to cover defects that could not have been  discovered by a reasonable and
customary inspection, in which case Paradigm shall have sixty (60) days from the
date of delivery to notify Vodavi, in writing,  of a rejection of such Products.
All written  rejections of any Products by Paradigm made in accordance with this
Section,  shall  specify in detail the  defects  and/or  nonconformities  in the
Products for which the rejection is made.

                  18.   Nondisclosure   and  Limited  Use  of  Confidential  and
Proprietary Information.  Each party hereto shall refrain from disclosing to any
third  parties,  or using  for any  purpose  unrelated  to this  Agreement,  the
existence of, or any of the terms of, this Agreement, all information concerning
the  pricing  of  the  Products,  any  customer  lists,  operating,   financial,
marketing,  sales or technical  information or other confidential or proprietary
information of the other, including, without limitation, information as to their
respective customers or the relationship  established hereunder;  and each party
hereto shall cause its  employees  and agents to refrain from  disclosing to any
third parties,  or using,  for any purpose  unrelated to the performance of this
Agreement,  any such confidential or proprietary  information of the other. Each
party hereto shall limit its use of any confidential or proprietary  information
received from the other to the purposes of this
                                        7

Agreement.  In addition,  Paradigm and Vodavi agree to keep confidential and not
disclose to any other person or entity, any writings between Paradigm and Vodavi
that are conspicuously marked or designated as "Confidential."

                  19.  Advertising and Promotion;  Use of Vodavi Name.  Paradigm
shall have the right, privilege and license during the term of this Agreement to
advertise and to promote the Products by telephone,  mail, newspaper,  magazine,
radio,  television  and any other lawful  means using the name  "Vodavi" and any
other tradename, symbol, trademark or corporate name used by Vodavi with respect
to the Products, provided such use conforms to standards and guidelines relating
thereto that Vodavi may furnish from time to time. Use of  tradenames,  symbols,
trademarks,  corporate  names  and  other  intellectual  property  of  Vodavi by
Paradigm  will be subject to  prepublication  or prior  review and  approval  by
Vodavi. The use of any tradenames, symbols, trademarks, corporate names or other
intellectual  property  rights of Vodavi by Paradigm shall not give Paradigm any
proprietary rights therein.

                  20. Warranty of Products.  Vodavi expressly  warrants that the
Products sold to Paradigm  will be free of defects in materials and  workmanship
under  normal use and service for the  warranty  period in  accordance  with the
terms and  conditions  set forth in Exhibit G  attached  hereto.  Repair  and/or
replacement  of  Products  by Vodavi  shall be as provided in Exhibit G attached
hereto.  VODAVI  MAKES NO  WARRANTY  OTHER  THAN THE ONE SET FORTH IN  EXHIBIT G
ATTACHED  HERETO.  THE  WARRANTY  SET  FORTH  THEREIN  IS IN LIEU  OF ALL  OTHER
WARRANTIES,  EXPRESSED OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY EXPRESSED OR
IMPLIED WARRANTY OF  MERCHANTABILITY,  OF FITNESS FOR A PARTICULAR  PURPOSE,  OR
AGAINST INFRINGEMENT,  AND IT CONSTITUTES THE ONLY WARRANTY MADE WITH RESPECT TO
THE PRODUCTS COVERED BY THESE TERMS AND CONDITIONS.  IN NO EVENT SHALL VODAVI BE
LIABLE FOR LOSS OF ANTICIPATED PROFITS, INCIDENTAL OR CONSEQUENTIAL DAMAGE, LOSS
OF TIME, OR OTHER LOSSES  INCURRED BY PARADIGM IN CONNECTION  WITH THE PURCHASE,
POSSESSION,  OPERATION,  OR  USE OF  THE  PRODUCTS,  SUCH  CLAIMS  BEING  HEREBY
EXPRESSLY WAIVED BY PARADIGM.

                  21. No Exclusive  Rights in Vodavi  Products  Generally.  This
Agreement is not to be construed  as granting any  exclusive  rights to Paradigm
with respect to the sale and  marketing of (a) any  telephones  manufactured  by
Vodavi not  bearing  Paradigm's  name or logo,  or (b) PBX  systems or  switches
manufactured by Vodavi for industries  other than the  Industries.  Vodavi shall

                            (a) Generally.  Except as otherwise  provided for in
this Agreement, if either party materially defaults in the performance of any of
its obligations under this Agreement,  the other party may defer its performance
hereunder  until the  default  is cured.  If the  material  default is not cured
within  forty-five  (45) days after the giving of written  notice thereof to the
defaulting party, at the option of the non-defaulting party exercised in writing
to the  defaulting  party,  this  Agreement  shall  terminate  at the end of the
forty-five (45) day period.  The  nondefaulting  party may also pursue all other
available legal and equitable remedies. A material default within the meaning of
this Section shall include,  without limitation, a failure of Paradigm to timely
pay any amounts owing to Vodavi, as provided in this Agreement.

                            (b)  Exclusion of Certain  Liability.  EXCEPT TO THE
EXTENT  OF ANY  LIABILITY  ARISING  PURSUANT  TO  SECTION  23  HEREOF,  UNDER NO
CIRCUMSTANCES  SHALL  VODAVI OR PARADIGM BE LIABLE TO THE OTHER FOR ANY SPECIAL,

accounts with Vodavi, including,  without limitation,  all sums due for Products
ordered prior to the effective date of termination or expiration.

                            (d) Survival of Certain Obligations. Notwithstanding

indemnification obligations set forth herein.

                            (e) Events of Default.  Notwithstanding anything set
forth in this Agreement to the contrary,  the occurrence of any of the following
events  shall  be  considered  an event  of  default  hereunder  for  which  the
nondefaulting  party may  terminate  this  Agreement  upon  five (5) days  prior
written  notice to the  defaulting  party:  (a) the filing of any  voluntary  or
involuntary  petition for bankruptcy or upon any agreement  (oral or written) in
respect of any arrangement for the benefit of creditors; (b) the sale, transfer,
conveyance  or other  disposition  of either  the  capital  stock or  beneficial
interest in the party  resulting  in a "change of control" of such party,  or of
substantially  all of the  assets of such  party in any case  without  the prior
written consent of the other party, which shall not be unreasonably withheld; or

liabilities to third parties,  including,  without limitation,  any governmental
agencies (including, without limitation, reasonable attorneys' fees) arising out
of or resulting from (i) the  performance or  nonperformance  by Paradigm of any
obligation of, or agreement made by,  Paradigm  relating to its  distribution of
the  Products,  or in  connection  with  the  performance  of  its  duties  as a
distributor;  and/or (ii) any  products  liability  resulting  from an action or
omission of Paradigm, its employees, agents, representatives or customers.

agencies (including, without limitation, reasonable attorneys' fees) arising out
of or resulting  from (i) any  products  liability  resulting  from an action or
omission of Vodavi, its employees,  agents or  representatives;  and/or (ii) any
suit or  proceedings  brought  against  Paradigm  to the extent it is based on a
claim that any of the Products  manufactured  and supplied by Vodavi to Paradigm
constitute a direct  infringement of a patent,  copyright or other  intellectual
property of a third person,  except where the alleged  infringement  is based on
(a) Vodavi compliance with any Product specification of Paradigm; (b) Paradigm's
use of a Product  in  combination  with any  other  product  (whether  direct or
contributory  infringement);  or (c) modification of a Product by Paradigm,  its
employees,  agents or  representatives  after the Product has been  delivered to
Paradigm.  If a suit or  proceeding is brought  against  Vodavi based on a claim
that the  applicable  Product  manufactured  and  supplied by Vodavi to Paradigm
constitutes a direct  infringement of a patent,  copyright or other intellectual
property of a third  person,  based on any of events  recited in (a), (b) or (c)
above in this Section  23(b),  Paradigm  shall  defend such claim and  indemnify
Vodavi for,  from and against  any and all  damages  and costs  awarded  against
Vodavi on the same basis as applicable to Paradigm above.  Paradigm acknowledges
and  agrees  that  Vodavi  is the  owner  of all  confidential  and  proprietary
information, software, firmware and protocols embodied in the Products (with the
exception of the Paradigm name and logo) and Paradigm  shall not take any action
or make any claims contrary thereto.

                  24.  Force  Majeure.  Neither  Paradigm  nor  Vodavi  shall be
responsible  for any loss or  damage  resulting  from any  delay or  failure  in
performing  any  provision of this  Agreement,  other than a delay or failure to
make payments  hereunder  when due, if the delay or failure  results  from:  (a)
transportation  shortages,  inadequate supply of labor, materials or energy; (b)
compliance with any law, ruling, order,  regulation,  requirement or instruction
of any  government  or any  department  or agency  thereof,  including,  without
                                       10
<PAGE>
limitation,  required payment of duties, taxes or the like; (c) acts of God; (d)
acts or omissions of the other party; or (e) fires,  strikes,  labor  slowdowns,

such causes shall extend performance  accordingly or excuse performance in whole
or in part, as may be necessary.

                  25.  Independent  Contractor.  Paradigm and Vodavi acknowledge
and agree that Vodavi is an independent contractor and that under this Agreement
neither Paradigm nor Vodavi shall be considered for any purpose to be the agent,
partner, franchisor, franchisee or joint venturer of the other. Nor shall Vodavi
or Paradigm have any obligation or  responsibility to act on behalf of or in the
name of the  other,  or the power or  authority  to bind the other in any manner
whatsoever.  Any representation to the contrary by Paradigm or by Vodavi, or the
employees or agents of either, shall be a material breach of this Agreement.

                            (a) Further  Assurances.  Each of the parties hereto

privilege under this Agreement shall operate as a waiver thereof,  nor shall any
single or partial exercise of any right, remedy, power or privilege preclude any
other or further  exercise of the same or of any other right,  remedy,  power or
privilege,  nor shall any waiver of any right,  remedy,  power or privilege with
respect to any occurrence be construed as a waiver of such right,  remedy, power
or privilege with respect to any other occurrence.  No waiver shall be effective
unless it is in writing and is signed by the party asserted to have granted such
waiver.

                            (h)  Provisions  Severable.  The  provisions of this
Agreement are  independent  of and severable  from each other,  and no provision
shall be  affected or 
                                       12

rendered  invalid or unenforceable by virtue of the fact that for any reason any
other or others of them may be invalid or unenforceable in whole or in part.

                            (i) Numbers of Days. In computing the number of days
for  purposes of this  Agreement,  all days shall be counted  (unless  otherwise
specified  herein),  including  Saturdays,  Sundays and holidays in the State of
Arizona; provided,  however, that if the final day of any time period falls on a
Saturday, Sunday or holiday in the State of Arizona, then the final day shall be
deemed to be the next day that is not a Saturday, Sunday or holiday in the State
of Arizona.

                            (j)  Attorneys'  Fees.  If any  action is brought to
enforce the provisions of this  Agreement,  the  prevailing  party in the action
shall be  entitled,  in  addition  to any other  relief,  to recover  reasonable
attorneys' fees and other costs and expenses incurred in the action in an amount
to be fixed and determined by the arbitrator(s) agreed upon by the parties or by
the court.

                            (k) Construction. The parties hereto acknowledge and
agree that each party has  participated  in the drafting of this  Agreement  and
that this  document has been  reviewed by the  respective  legal counsel for the
parties  hereto  and  that  the  rule of  construction  to the  effect  that any
ambiguities are to be resolved against the drafting party will not be applied to

party  shall be drawn  from the fact  that one  party has  drafted  any  portion
hereof. The headings in this Agreement are inserted for convenience only, and do
not define, limit, or expand the intent, scope or meaning of this Agreement.

                            (l) Amendment. This Agreement may only be amended or
modified by written agreement signed by all of the parties hereto.

                  IN WITNESS WHEREOF,  the parties have caused this Agreement to
