                               NOTES TO UNAUDITED
                   CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial  information  and the  instructions  to Form  10-Q and  Rule  10-01 of
Regulation  S-X.  Accordingly,  they do not include all of the  information  and
notes  required  by  generally  accepted  accounting   principles  for  complete
financial  statements.  In  the  opinion  of  management,  all  adjustments  and
reclassifications  considered  necessary for a fair and comparable  presentation
have been included and are of a normal recurring  nature.  Operating results for
the three  months and the six months ended June 28,  1997,  are not  necessarily
indicative of the results that may be expected for the year ending  December 31,
1997. The accompanying  financial  statements should be read in conjunction with
the Company's most recent Annual Report and Form 10-K.

1.    BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

      A. Principles of  Consolidation - The  consolidated  financial  statements
      include the accounts of Microtest,  Inc. and its wholly-owned subsidiaries
      (collectively, the "Company"). The Company develops, markets, and supports
      products  that make it easier to install,  service,  and manage local area
      networks ("LANs").

      B. For interim  reporting  purposes,  the Company ends its quarters on the
      Saturday  closest to the  calendar  quarter end,  with the fourth  quarter
      ending on December 31, 1997.

      C. New Accounting  Standards - In February 1997, the Financial  Accounting
      Standards Board ("FASB") issued Statement of Accounting  Standards No. 128
      "Earnings  Per  Share,"  which is  effective  for both  interim and annual
      periods  ending after  December 15, 1997. The Company does not believe the
      adoption of the  standard  will have a  significant  effect on  previously
      reported earnings per share.

      The FASB recently issued SFAS No. 130 on "Reporting  Comprehensive Income"
and SFAS No. 131 on  "Disclosures  about  Segments of an Enterprise  and Related
Information."  The "Reporting  Comprehensive  Income"  standard is effective for
fiscal  years  beginning  after  December 15,  1997.  The  standard  changes the
reporting of certain items currently reported in the common stock equity section
of the balance  sheet.  The  Company is  currently  evaluating  what impact this
standard will have on the Company's financial statements.

      The "Disclosures about Segments of an Enterprise and Related  Information"
standard is effective for fiscal years  beginning  after December 15, 1997. This
standard  requires  that  public  companies  report  certain  information  about
operating segments in their financial  statements.  It also establishes  related
disclosures about products and services,  geographic areas, and major customers.
The Company is currently  evaluating  what impact this standard will have on its
disclosures.
                                       6
<PAGE>
      D.  Reclassifications  - Certain  reclassifications  have been made to the
      1996   consolidated   financial   statements   to   conform  to  the  1997
      presentation.

2.    COMMITMENTS AND CONTINGENCIES

      Future minimum rental  payments due under the Company's  office  operating

      Total minimum rental payments                    $3,509
                                                       ======

      In April 1997,  the two  shareholder  lawsuits  filed against the Company,
      Richard G. Meise,  Richard R. Douglas and David C. Bolles in September and
      October 1996 relating to the reporting of interim  results were  dismissed
      without prejudice.

      The  Company is involved in certain  other legal  matters,  the outcome of
      which  is  currently  unknown.  Management  believes  that  the  Company's
      liability,  if  any,  will  not  have a  material  adverse  effect  on the
      Company's financial condition and results of operations.

Item 2. Management's  Discussion and Analysis of Financial Condition and Results
of Operations

      This Quarterly  Report on Form 10-Q contains  forward-looking  statements.
The  words  "believe,"   "expect,"   "anticipate,"  and  "project"  and  similar
expressions identify forward-looking statements, which speak only as of the date
the statement was made. Such  forward-looking  statements are within the meaning
of that term in Section  27A of the  Securities  Act of 1933,  as  amended,  and
Section 21E of the Securities Exchange Act of 1934, as amended.  Such statements
may  include,  but not be limited to,  projections  of revenue,  income or loss,
capital expenditures, plans for future operations, financing needs or plans, and
plans  relating to products or services of the Company,  as well as  assumptions
relating to the foregoing.

      Statements in Exhibit 99 to this Quarterly  Report on Form 10-Q,  describe
factors,  among  others,  that could  contribute  to or cause such  differences.
Additional  factors that could cause actual  results to differ  materially  from
those   expressed  in  such   forward-looking   statements   are  set  forth  in
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations"  in the  Company's  Annual  Report on Form  10-K for the year  ended
December 31, 1996.

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

During both the second  quarter and the six months  ended June 28,  1997,  total
revenues  decreased  compared  to the same  periods in 1996 due  primarily  to a
general  softness in network  industry sales,  which has impacted the results of
the entire industry segment, and intensified competition.  The Company currently
believes  that its  third  quarter  operating  results  also  will be  adversely
affected  by the  general  softness  in  industry  sales  and the  impact of new
products to be introduced is not presently determinable.

Gross profit  decreased  in absolute  dollars but  increased as a percentage  of
revenues  during  the second  quarter of 1997 and the six months  ended June 28,
1997 compared to the same periods in 1996.  The decrease in absolute  dollars is
due to the  decrease  in  revenues.  Gross  profit as a  percentage  of revenues
improved  during the second  quarter of 1997 due to a reduction in the Company's
discount structure relating to the  manufacturers'  representative  program that
was  introduced  near  the end of the  second  quarter  of  1996,  which in turn
increased sales and marketing expenses (see below).

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

For both the quarter  ended and the six months  ended June 28,  1997,  sales and
marketing  expenses  increased in absolute  dollars and as a percentage of total
revenues  compared to the same period in 1996. The increase is due largely to an
increase in employees  and other costs  attributable  to  Logicraft  Information
Systems  ("Logicraft")  acquired  during the fourth quarter of 1996. The Company
restructured  its sales  force  during the first and second  quarters of 1997 to
fully  integrate   Logicraft  into  the  sales  mix.  Costs  relating  to  these
restructurings  totaled  approximately  $223,000  during  the first half of this
year.  Additionally,  the Company reduced its discount  structure,  as mentioned
above, and has experienced increased sales commissions as a result.

Research  and  development  expenses  increased  in  absolute  dollars  and as a
percentage of total revenues in both the second quarter and the six months ended
June 28,  1997,  compared  with the same  periods in 1996.  The  increase  stems
primarily from an increase in the number of employees due to the  acquisition of
Logicraft  during the fourth  quarter of 1996, as well as the  development  of a
higher number of prototypes than experienced  during the second quarter of 1996.
During the first and second  quarters  of 1997,  the  Company  restructured  its
research  and  development  work  force to fully  integrate  Logicraft  into the
research  and  development  process.  To date,  the Company has expensed all R&D
costs as incurred.

General and administrative expenses remained consistent in both absolute dollars
and as a percentage of total  revenues  during the second quarter ended June 28,
1997,  compared  to the same  period  in 1996,  whereas  G&A  increased  in both
categories  during the six  months  ended June 28,  1997,  compared  to the same
period in 1996.  This increase is 
                                       9

mainly the result of the increase in personnel  and other  administrative  costs
attributable to Logicraft acquired during the fourth quarter of 1996.

Rate
- --------------------------------------------------------------------------------

The Company's  effective tax rate  experienced a decrease during both the second
quarter and the six months ended June 28, 1997,  compared to the same periods of
the preceding year  primarily  because the research and  development  tax credit
afforded under Section 41 of the Internal  Revenue Code, which was not available
during the three months and six months ended June 29, 1996, was  reinstituted in
the third quarter of 1996.

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

Net income  decreased  in both  absolute  dollars and as a  percentage  of total
revenues  for both the second  quarter and the six months ended June 28, 1997 as
compared  to the same  periods in 1996.  This  decrease  is due  primarily  to a
decrease in revenues  coupled with an increase in personnel and other  operating
expenses relating to Logicraft as discussed above .

Liquidity and Capital Resources
- -------------------------------

The Company has financed its operations  primarily  through operating cash flows
and  equity  financings.  At June  28,  1997,  the  Company  had  cash  and cash
equivalents  of $5.3 million.  This  represents a $5.0 million  decrease in cash
equivalents  during  the six  months  ended  June 28,  1997,  due  primarily  to
increases in inventory  resulting  from lower than expected sales and the timing
of payables.  As a result of the use of cash and cash  equivalents over the past
three quarters,  the Company obtained a $10 million  unsecured  revolving credit
facility with Bank of America  during the second  quarter which will be used for
general  corporate and working  capital  purposes.  No amounts were  outstanding
under this credit  facility at June 28,  1997.  Cash flows from  operations  and
available  cash under the credit  facility will be sufficient to meet cash needs
in the foreseeable future.

                               The Credit Facility
                               -------------------

     2.01 The Revolving Facility.  (a) From time to time during the Availability
Period,  subject to the terms and  provisions  hereof,  the Bank, on a revolving
basis, will make dollar Advances to the Borrower.

          (b) The  aggregate  of all Advances may not exceed at any one time the
amount of $10,000,000.

     2.02  Advances  Under the  Revolving  Facility.  (a)  Subject  to the other
provisions of this Section,  Advances  under the Revolving  Facility  shall bear
interest at a rate per annum equal to the Reference  Rate plus 0.00%  percentage
points per annum (the Reference Rate plus 0.00%  percentage  points per annum is
referred to herein as the  "Floating  Rate").  The  Borrower  shall pay interest
monthly,  on the last day of each month  until the last day of the  Availability
Period,  on which date all accrued and unpaid interest shall be due and payable.
The Borrower shall repay the principal  amount of each Reference Rate Advance on
the  date  such  advance  is  converted  into an  Offshore  Rate  Advance  under
subsection (b) below, and on the last day of the Availability Period.

          (b) In lieu of the interest  rate  described  above,  the Borrower may
elect during the  Availability  Period to have all or portions of Advances under
the Revolving Facility be in dollars and bear interest at the Offshore Rate plus
1.50%  per  annum  during an  Offshore  Rate  Interest  Period,  subject  to the
following requirements:

               (i) Each  Offshore  Rate Advance  shall be for an amount not less
     than $500,000.

               (ii) The  Borrower  shall  pay  interest  on each  Offshore  Rate
     Advance  on the last day of the  Offshore  Rate  Interest  Period  for such
     Advance; provided, however, that if any Interest Period for a Offshore Rate
     Advance  exceeds three months,  interest  shall also be payable on the date
     which falls three months after the beginning of such Interest Period and on
     each date which falls three months after any such  interest  payment  date.
     The  Borrower  shall  repay the  principal  balance of each  Offshore  Rate
     Advance on the last day of the Offshore Rate Interest Period for such
                                        6
<PAGE>
     Advance,  and (if  sooner  occurring)  on the last day of the  Availability
     Period.

               (iii) Any payment of an Offshore  Rate Advance  prior to the last
     day  of the  Offshore  Rate  Interest  Period  for  such  Advance,  whether
     voluntary, by reason of acceleration or otherwise,  including any mandatory
     payments  required  under  this  Agreement  and  applied  by the Bank to an
     Offshore  Rate  Advance,  shall be  accompanied  by the  amount of  accrued
     interest  on the  amount  repaid and by the  amount  (if any)  required  by
     Section 3.11.

     2.03 Mandatory Payment.  If at any time and for any reason the total amount
of credit  outstanding  under this Agreement  exceeds the  limitations set forth
herein,  the  Borrower  shall pay to the Bank,  upon  demand,  the amount of the
excess.  Payments  under this Section may be applied to the  obligations  of the
Borrower to the Bank in the order and manner as the Bank in its  discretion  may
determine.

     2.04  Facility  Fee.  The Borrower  shall pay to the Bank a  non-refundable
facility  fee of  $20,000  on or  before  the  execution  and  delivery  of this
Agreement by the parties.

     2.05 Commitment Fee. The Borrower shall pay to the Bank a commitment fee at
the rate of 0.375% per annum on the average  daily unused  portion of the credit
provided  under  this  Agreement.  The  commitment  fee shall be  computed  on a
calendar quarter basis,  except for the first period which shall commence on the
Closing Date and end on June 30, 1997 and the last period which shall end on the
last day of the  Availability  Period.  The  commitment  fee shall be payable in
arrears on July 1, 1997, on the first day of each  successive  calendar  quarter
thereafter, and on the last day of the Availability Period.

     2.06 Default Rate.  Upon the occurrence and during the  continuation of any
Event  of  Default,  and  without  constituting  a waiver  of any such  Event of
Default,  Advances under the Revolving  Facility shall at the option of the Bank
bear  interest at a rate per annum which is 2% per annum higher than the rate of
interest otherwise provided under this Agreement.

     2.07  Early  Termination  of  Commitment.  The  Borrower  may at  any  time
terminate the Bank's  commitment  to extend  credit  hereunder by giving no less
than five Business  Days' prior notice to the Bank and paying in full the entire
amount of credit outstanding hereunder, together with any sums due under Section
3.11.  All accrued  commitment  fees to, but not including the effective date of
any termination of the  commitment,  shall be paid on the effective date of such
termination.

                                   ARTICLE III

            Extensions of Credit, Payments and Interest Calculations
            --------------------------------------------------------

     3.01 Requests for Credit.  Each request for an extension of credit shall be
made  in  writing  on a form  acceptable  to the  Bank  or in any  other  manner
acceptable to the Bank.

     3.02  Disbursements  and Payments.  Each  disbursement by the Bank and each
payment by the Borrower under this  Agreement  shall be made in the funds and at
such branch of the Bank as the Bank may from time to time select.

     3.03 Branch  Accounts.  Each extension of credit under this Agreement shall
be made for the account of such branch,  office, or affiliate of the Bank as the
Bank may from time to time select.

     3.04 Evidence of Indebtedness.  Principal, interest, and all other sums due
to the Bank  under  this  Agreement  shall be  evidenced  by  entries in records
maintained by the Bank,  and, if required by the Bank,  by a promissory  note or
notes.  Each  payment  on and any  other  credits  with  respect  to  principal,
interest,  and all other sums due under this  Agreement  shall be  evidenced  by
entries  to  records  maintained  by the  Bank.  The loan  accounts  or  records
maintained by the Bank shall be conclusive  absent  manifest error of the amount
of the credit  extended  hereunder  and the interest and payments  thereon.  Any
failure  to so  record  or any error in doing so shall  not,  however,  limit or
otherwise  affect the  obligation  of the  Borrower  hereunder to pay any amount
owing.

     3.05 Interest  Calculation.  Interest  based on the Reference Rate shall be
computed on the basis of a  365/366-day  year,  actual days  elapsed.  All other
interest and fees payable under this Agreement shall be computed on the basis of
a 360 day year and actual  days  elapsed,  which  results in more  interest or a
larger fee than if a 365-366 day year were used.

     3.06 Late Payments;  Compounding. Any sum payable by the Borrower hereunder
(including unpaid interest) if not paid when due shall bear interest (payable on
demand) from its due date until payment in full at a rate per annum equal to the
Floating Rate plus 2% per annum.  At the option of the Bank,  in each  instance,
any sum payable hereunder which is not paid when due (including unpaid interest)
may be added to principal of the Revolving  Facility and shall  thereafter  bear
interest at the rate applicable to principal.

     3.07 Business Day. Any sum payable by the Borrower  hereunder which becomes
due on a day which is not a Business  Day shall be due on the next  Business Day
after such due date, unless, in the case of an Offshore Rate Loan, the result of
such extension would be to carry such Offshore Rate Interest Period into another
calendar month, in which event such Offshore Rate
                                       8
<PAGE>
Interest  Period  shall  end on the  immediately  preceding  Business  Day.  Any
payments  received  by the Bank on a day  which is not a  Business  Day shall be
deemed to be received on the next Business Day after such date of receipt.

     3.08 Taxes and Other Charges. (a) (i) If any taxes (other than taxes on net
income (A) imposed by the country or any subdivision of the country in which the
Bank's  principal office or actual lending office is located and (B) measured by
the United  States  taxable  income the Bank would have received if all payments
under or in respect of this Agreement and any  instrument or agreement  required
hereunder  were exempt from taxes levied by the  Borrower's  country) are at any
time  imposed  on any  payments  under or in respect  of this  Agreement  or any
instrument  or  agreement  required  hereunder  including,  but not  limited to,
payments made pursuant to this  Section,  the Borrower  shall pay all such taxes
and shall also pay to the Bank,  at the time  interest is paid,  all  additional
amounts which the Bank  specifies as necessary to preserve the  after-tax  yield
the Bank would have received if such taxes had not been imposed.

               (ii) The additional  amounts  necessary to preserve the after-tax
yield the Bank would have  received if such taxes had not been imposed  shall be
calculated pursuant to the formula:

                                       (w)(t)(i)
                                 y = -----------
                                         1-w-t

where the terms are defined as follows:

                           y = additional payment to be made to the Bank

                           w = withholding tax rate levied by foreign
                               government

                           t  = the Bank's combined Federal and state tax rate

                           i  = amount  of  interest  to be paid on Credit
                                (computed  by  using  the  Offshore  Rate or
                                Reference  Rate  or  other  index  rate,  as
                                applicable  plus the quoted margin over such
                                rate)

                           1  = one

          (b) The  Borrower  will provide the Bank with  original tax  receipts,
notarized  copies of tax  receipts,  or such other  documentation  as will prove
payment of tax in a court of law applying  the United  States  Federal  Rules of
Evidence, for all taxes paid by the Borrower pursuant to subsection (a) above.
                                        9
<PAGE>
The Borrower will deliver receipts to the Bank within 30 days after the due date
for the related tax.

     3.09  Illegality.  (a) If the Bank determines that (i) the  introduction of
any law, rule, regulation, treaty, or determination of an arbitrator or court or
other  governmental  authority  or any  change  in or in the  interpretation  or
administration  thereof has made it unlawful,  or that any central bank or other
governmental authority has asserted that it is unlawful, for the Bank to make or
extend any  Advance or other  credit  under this  Agreement,  or (ii) any order,
judgment, or decree of any governmental  authority or arbitrator purports by its
terms to enjoin or  restrain  the Bank from making or  extending  any Advance or
other credit hereunder, then, on notice thereof by the Bank to the Borrower, the
obligation  of the Bank to make or extend such  Advance or other credit shall be
suspended until the Bank shall have notified the Borrower that the circumstances
giving rise to such determination no longer exist.

     (b) If the Bank  determines  that it is  unlawful  for it to  maintain  any
Offshore Rate Advance hereunder,  the Borrower shall prepay in full all Offshore
Rate Advances then outstanding,  together with interest accrued thereon,  either
on the last day of the applicable  Offshore Rate Interest Period if the Bank may
lawfully  continue to maintain  such Advances to such day and such loans have an
interest  period,  or  immediately,  if the Bank may not  lawfully  continue  to
maintain such Advances or such loans have no interest period,  together with any
amounts required to be paid in connection therewith pursuant to Section 3.11.

     3.10 Increased  Costs.  The Borrower shall pay to the Bank, on demand,  the
Bank's costs or losses arising from any statute or regulation, or any request or
requirement of a regulatory  agency which is applicable to all national banks or
a class of all  national  banks.  The costs and losses will be allocated to this
facility in a manner  determined by the Bank, using any reasonable  method.  The
costs include the following:

          (a) any reserve or deposit requirements; and

          (b)  any  capital  requirements  relating  to the  Bank's  assets  and
commitments for credit.

     3.11 Funding  Losses.  The Borrower  shall  reimburse the Bank and hold the
Bank  harmless from any loss or expense which the Bank may sustain or incur as a
consequence  of the failure of the Borrower to make any payment or prepayment of
principal  of any Advance  hereunder  made at a rate of interest  related to the
Offshore Rate (including  payments made after any acceleration  thereof),  or to
borrow at such a rate, or the  prepayment of an Advance which bears  interest at
such a rate on a day  which  is not the  last day of the  interest  period  with
respect thereto (including payments made after any acceleration thereof or
                                       10
<PAGE>
because the total amount of credit exceeds the limitations set forth herein), or
the redenomination and conversion,  upon the occurrence of any Event of Default,
of an Advance  which bears  interest at such a rate;  including any such loss or
expense  arising from the liquidation or reemployment of funds obtained by it to
maintain its Advances made at a rate related to the Offshore  Rate  hereunder or
from fees payable to terminate  any deposits from which such funds were obtained
or deemed obtained.

     3.12 Inability to Determine  Rates. The Bank has no obligation to accept an
election for an Offshore Rate Advance if (a) deposits in the applicable currency
and in the principal  amount,  and for the period equal to the interest  period,
for such Advance are not available in the applicable  funding market; or (b) the
Offshore  Rate does not  accurately  reflect the cost of such  Advance.  Nothing
contained herein shall,  however,  obligate the Bank to obtain the funds for any
Advance in any particular manner.

     3.13  Certificate  of the Bank.  If the Bank  claims any  reimbursement  or
compensation  pursuant  to  Section  3.10 or Section  3.11,  then the Bank shall
deliver to the Borrower a certificate  setting  forth in  reasonable  detail the
amount payable to the Bank thereunder and such  certificate  shall be conclusive
and binding on the Borrower in the absence of manifest error.

     3.14 Debits to Borrower's Account.  The Borrower hereby authorizes the Bank
to debit the Borrower's deposit account number 235336440 at the Phoenix, Arizona
office of the Bank in the  amount of  principal,  interest,  fees,  or any other
amount due under this  Agreement or under any  instrument or agreement  required
under this Agreement. The Bank may, at its option, debit the account on the date
such amounts become due, or, if such due date is not a Business Day, on the next
Business Day after such due date. If there are insufficient funds in the account
to cover the amount  debited to the accounts in  accordance  with this  Section,
such debit may be reversed in whole or in part, at the option of the Bank in its
sole discretion, and the amount not debited shall be deemed to remain unpaid.

     3.15  Survival.  The  agreements  and  obligations  of the  Borrower  under
Sections 3.08 through 3.11 shall survive the  expiration or  termination  of the
commitment to extend credit  hereunder and the payment of all other  obligations
of the Borrower hereunder.

under each of the Credit Documents,  or accorded by law,  including the right to
resort to any or all security for any credit accommodation described herein, and
to exercise any or all of the rights of a beneficiary  or secured party pursuant
to applicable law.

All rights, powers, and remedies of the Bank may be exercised at any time by the
Bank and from time to time  after the  occurrence  of an Event of  Default.  All
rights,  powers,  and remedies of the Bank in connection with each of the Credit
Documents are cumulative and not exclusive and shall be in addition to any other
rights, powers, or remedies provided by law or equity.

                                  Miscellaneous
                                  -------------

     9.01  Successors and Assigns.  This  Agreement  shall bind and inure to the
benefit of the  parties  hereto and their  respective  successors  and  assigns;
provided,  however,  that the  Borrower  shall not assign this  Agreement or any
other  Credit  Document  or any of the  rights,  duties  or  obligations  of the
Borrower hereunder without the prior written consent of the Bank.

     9.02  Consents  and  Waivers.  No  failure  to  exercise  and no  delay  in
exercising,  on the part of the Bank,  any right,  remedy,  power,  or privilege
hereunder,  shall operate as a waiver  thereof;  nor shall any single or partial
exercise of any right, remedy,  power, or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right,  remedy,  power,
or  privilege.  No consent or waiver  under this  Agreement  shall be  effective
unless in writing.  No waiver of any breach or default  shall be deemed a waiver
of any breach or default thereafter occurring.

     9.03 Governing Law. This Agreement shall be governed by and construed under
the laws of the State of California.

     9.04 Costs and  Attorneys'  Fees.  The Borrower  shall,  whether or not the
transactions contemplated hereby shall be consummated, pay or reimburse the Bank
on demand for all costs and expenses incurred by the Bank in connection with the
development,  preparation,  delivery,  administration, and execution of, and any
amendment,  supplement,  waiver or modification to, this Agreement and any other
Credit Document and the consummation of the transactions contemplated hereby and
thereby,  including reasonable attorney fees and disbursements and the allocated
cost of internal  counsel and  disbursements,  incurred by the Bank with respect
thereto;  and in  connection  with the  enforcement,  attempted  enforcement  or
preservation of any rights or remedies  hereunder or under any Credit  Document,
including  any  "workout"  or  restructuring  under  this  Agreement,  including
attorney fees and  disbursements  and the allocated cost of internal counsel and
disbursements. The agreements and obligations of the Borrower under this Section
shall survive the  expiration or  termination of the commitment to extend credit
hereunder and the payment of all other obligations of the Borrower hereunder.

     9.05 Integration; Amendment. This Agreement, together with the other Credit
Documents,  embodies the entire agreement and understanding between the Borrower
and the Bank. This Agreement may be amended or modified only in writing,  signed
by the Borrower and the Bank.

     9.06 Borrower's Documents.  The Bank shall be under no obligation to return
any schedules, invoices, statements,
                                       25
<PAGE>
budgets, forecasts,  reports or other papers delivered by the Borrower and shall
destroy  or  otherwise  dispose  of  same  at  such  time  as the  Bank,  in its
discretion, deems appropriate.

     9.07  Participations.  The  Bank  may  at  any  time  sell,  assign,  grant
participations  in, or otherwise  transfer to any other Person (a "Participant")
all or part of the  obligations  of the Borrower  under this  Agreement  and any
other Credit Document.  The Borrower  authorizes the Bank and each  Participant,
upon the  occurrence  of an Event of  Default,  to proceed  directly by right of
setoff,  banker's  lien, or otherwise,  against any assets of the Borrower which
may be in the hands of the Bank or such Participant,  respectively. The Borrower
authorizes  the  Bank  to  disclose  to  any  prospective  Participant  and  any
Participant  any and all  information  in the Bank's  possession  concerning the
Borrower and its Subsidiaries, this Agreement or any other Credit Document.

     9.08 General  Indemnification.  The Borrower  shall pay and  indemnify  the
Bank, the Bank's parent  company and  affiliates,  and each of their  respective
officers, directors,  employees, counsel, agents and attorneys-in-fact (each, an
"Indemnified  Person")  harmless  from  and  against  any and  all  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
charges, expenses, or disbursements (including attorneys' fees and disbursements
and the allocated  costs of internal  counsel) of any kind or nature  whatsoever
with  respect  to  the  execution,  delivery,   enforcement,   performance,  and
administration  of  this  Agreement  and  any  other  Credit  Documents,  or the
transactions   contemplated  hereby  and  thereby,   and  with  respect  to  any
investigation,   litigation,  or  proceeding  related  to  this  Agreement,  any
violation of any Environmental Law by the Borrower or its Subsidiaries, any use,
generation,  manufacture,  production,  storage,  release,  threatened  release,
discharge,  disposal  or  presence  (whether  actual or  alleged) of a Hazardous
Substance on, under or about the property or operations of or property leased to
the  Borrower  or any of its  Subsidiaries,  any  transportation  from or  other
off-site management of any Hazardous Substance generated or used by the Borrower
or any  of its  Subsidiaries,  or the  loans  and  other  extensions  of  credit
hereunder or the use of the  proceeds  thereof,  whether or not any  Indemnified
Person is a party thereto (all the  foregoing,  collectively,  the  "Indemnified
Liabilities"); provided, that the Borrower shall have no obligation hereunder to
any Indemnified Person with respect to Indemnified  Liabilities arising from the
gross  negligence  or  willful  misconduct  of  such  Indemnified   Person.  The
agreements and  obligations of the Borrower under this Section shall survive the
expiration or termination  of the commitment to extend credit  hereunder and the
payment of all other obligations of the Borrower hereunder.

     9.09  Arbitration;  Reference  Proceeding.  (a) Any  controversy  or  claim
between or among the parties,  including but not limited to those arising out of
or relating to this Agreement or any other Credit  Document or other  agreements
or
                                       26
<PAGE>
instruments  relating  hereto or delivered in connection  herewith and any claim
based on or arising from an alleged  tort,  shall at the request of any party be
determined by arbitration. The arbitration shall be conducted in accordance with
the United States  Arbitration  Act (Title 9, U.S.  Code),  notwithstanding  any
choice of law provision in this Agreement, and under the Commercial Rules of the
American  Arbitration  Association  ("AAA").  The arbitration shall be conducted
within the following California county or counties: San Francisco,  Santa Clara.
The arbitrator(s) shall give effect to statutes of limitation in determining any
claim.  Any  controversy  concerning  whether  an issue is  arbitrable  shall be
determined  by the  arbitrator(s).  Judgment upon the  arbitration  award may be
entered in any court having jurisdiction.  The institution and maintenance of an
action for judicial relief or pursuit of a provisional or ancillary remedy shall
not constitute a waiver of the right of any party,  including the plaintiff,  to
submit the  controversy or claim to arbitration if any other party contests such
action for judicial relief.

          (b)  Notwithstanding the provisions of subsection (a) of this Section,
no controversy or claim shall be submitted to arbitration without the consent of
all parties if, at the time of the  proposed  submission,  such  controversy  or
claim  arises from or relates to an  obligation  to the Bank which is secured by
real property collateral located in California. If all parties do not consent to
submission of such a controversy  or claim to  arbitration,  the  controversy or
claim shall be determined as provided in subsection (c) of this Section.

          (c) A controversy  or claim which is not submitted to  arbitration  as
provided and limited in subsections  (a) and (b) of this Section  shall,  at the
request of any party, be determined by a reference in accordance with California
Code of Civil  Procedure  Sections 638 et seq. If such an election is made,  the
parties shall  designate to the court a referee or referees  selected  under the
auspices  of the  AAA  in  the  same  manner  as  arbitrators  are  selected  in
AAA-sponsored proceedings. The presiding referee of the panel, or the referee if
there is a single  referee,  shall  be an  active  attorney  or  retired  judge.
Judgment upon the award rendered by such referee or referees shall be entered in
the court in which such  proceeding was commenced in accordance  with California
Code of Civil Procedure Sections 644 and 645.

          (d) No provision of this paragraph  shall limit the right of any party
to this Agreement to exercise  self-help  remedies such as setoff,  to foreclose
against or sell any real or personal  property  collateral  or  security,  or to
obtain provisional or ancillary remedies from a court of competent  jurisdiction
before,  after, or during the pendency of any  arbitration or other  proceeding.
The  exercise of a remedy does not waive the right of either  party to resort to
arbitration  or reference.  At the Bank's  option,  foreclosure  under a deed of
trust or mortgage may be accomplished either by exercise of
                                       27
<PAGE>
power of sale under the deed of trust or mortgage or by judicial foreclosure.

     9.10 Notices. (a) All notices,  requests and other communications  provided
for  hereunder  shall be in writing  and mailed or  delivered  to a party at its
address  specified on the signature  pages  hereof,  or to such other address as
shall be designated by such party in a written notice to the other parties.

          (b) All such notices and  communications  shall,  when  transmitted by
overnight delivery,  be effective when delivered for overnight  delivery,  or if
personally delivered,  upon such personal delivery, except that notices pursuant
to Article II shall not be effective until actually received by the Bank.

          (c) The  Borrower  acknowledges  and agrees that any  agreement of the
Bank  pursuant to Article II to receive  notices by  telephone  or  facsimile is
solely  for  the  convenience  and at the  request  of the  Borrower.  Telephone
requests may be made by any  individual  identified  in writing to the Bank on a
form acceptable to the Bank as being authorized to make such requests.  The Bank
shall be entitled to rely upon any written or telephone  request from persons it
reasonably  believes to be  authorized  by the  Borrower  to make such  requests
without making independent  inquiry.  The Borrower assumes the full risk of, and
the Bank shall not be responsible for, any delays or errors in transmission, and
the obligation of the Borrower to repay the loans and other extensions of credit
hereunder  shall not be  affected  in any way or to any extent by any failure by
the Bank to receive written  confirmation of any telephonic or facsimile  notice
or the receipt by the Bank of a confirmation which is at variance with the terms
understood by the Bank to be contained in the telephonic or facsimile notice.

     9.11 Headings; Interpretation. Article, section, and paragraph headings are
for  reference  only and shall not affect the  interpretation  or meaning of any
provisions  of this  Agreement.  The  meaning of defined  terms shall be equally
applicable  to the  singular and plural  forms of the defined  terms.  The words
"hereof",  "herein",  "hereunder"  and words of similar import when used in this
Agreement  shall refer to this  Agreement  as a whole and not to any  particular
provision of this  Agreement;  and Article,  subsection,  section,  schedule and
exhibit  references are to this Agreement unless otherwise  specified.  The term
"including" is not limiting and means  "including  without  limitation."  In the
computation of periods of time from a specified date to a later  specified date,
the word "from" means "from and including"; the words "to" and "until" each mean
"to but excluding", and the word "through" means "to and including."

     9.12 Severability.  The illegality or  unenforceability of any provision of
this Agreement or any instrument or agreement  required  hereunder  shall not in
any way affect or impair the
                                       28
<PAGE>
legality or enforceability of the remaining  provisions of this Agreement or any
instrument or agreement required hereunder.

     9.13  Counterparts.  This Agreement may be executed in as many counterparts
as may be deemed necessary or convenient, and by the different parties hereto on
separate  counterparts  each of  which,  when so  executed,  shall be  deemed an
original  but all  such  counterparts  shall  constitute  but  one and the  same
agreement.

     9.14 Waiver of Jury Trial.  IF A  CONTROVERSY  OR CLAIM IS NOT SUBMITTED TO
ARBITRATION AS PROVIDED AND LIMITED IN  SUBSECTIONS  (a) AND (b) OF SECTION 9.09
OR IS NOT  DETERMINED BY A REFERENCE AS PROVIDED IN SUBSECTION (c) OF SUBSECTION
9.09, THEN THE BORROWER AND THE BANK WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY
JURY OF ANY CLAIM OR CAUSE OF ACTION  BASED UPON OR ARISING OUT OF OR RELATED TO
THIS AGREEMENT,  THE OTHER CREDIT  DOCUMENTS,  OR THE TRANSACTIONS  CONTEMPLATED
HEREBY OR THEREBY,  IN ANY ACTION,  PROCEEDING  OR OTHER  LITIGATION OF ANY TYPE
BROUGHT BY ANY OF THE  PARTIES  AGAINST ANY OTHER  PARTY OR ANY  PARTICIPANT  OR
ASSIGNEE,  WHETHER WITH RESPECT TO CONTRACT CLAIMS,  TORT CLAIMS,  OR OTHERWISE.
THE  BORROWER  AND THE BANK EACH  AGREE  THAT ANY SUCH  CLAIM OR CAUSE OF ACTION
SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY.  WITHOUT LIMITING THE FOREGOING,
THE  PARTIES  FURTHER  AGREE THAT THEIR  RESPECTIVE  RIGHT TO A TRIAL BY JURY IS
WAIVED BY  OPERATION  OF THIS  SECTION AS TO ANY ACTION,  COUNTERCLAIM  OR OTHER
PROCEEDING  WHICH  SEEKS,  IN WHOLE OR IN PART,  TO  CHALLENGE  THE  VALIDITY OR
ENFORCEABILITY  OF THIS AGREEMENT OR THE OTHER CREDIT DOCUMENTS OR ANY PROVISION
HEREOF  OR  THEREOF.  THIS  WAIVER  SHALL  APPLY TO ANY  SUBSEQUENT  AMENDMENTS,
RENEWALS,  SUPPLEMENTS OR  MODIFICATIONS  TO THIS AGREEMENT AND THE OTHER CREDIT
DOCUMENTS.
                                       29

     IN WITNESS  WHEREOF,  the parties hereto have executed this Agreement as of

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

     THIS FIRST  AMENDMENT TO CREDIT  AGREEMENT (the  "Amendment"),  dated as of
June 24,  1997,  effective  as of June 3, 1997,  is entered  into by and between
MICROTEST,  INC. (the "Borrower") and BANK OF AMERICA NATIONAL TRUST AND SAVINGS
ASSOCIATION (the "Bank").

                                    RECITALS
                                    --------

     A. The Borrower and the Bank are parties to a Credit  Agreement dated as of
June 3, 1997 (the "Credit  Agreement"),  pursuant to which the Bank has extended
certain credit facilities to the Borrower.

     B. The Borrower has requested that the Bank agree to certain  amendments of
the Credit Agreement.

     C. The Bank is willing to amend the Credit Agreement,  subject to the terms
and conditions of this Amendment.

     NOW,  THEREFORE,  for valuable  consideration,  the receipt and adequacy of
which are hereby acknowledged, the parties hereto hereby agree as follows:

     1. Defined Terms.  Unless otherwise defined herein,  capitalized terms used
herein  shall  have  the  meanings,  if any,  assigned  to  them  in the  Credit
Agreement.

     2. Amendments to Credit Agreement.

          (a)  Section  7.01 of the  Credit  Agreement  shall be  amended by (i)
deleting the word "and" at the end of  subsection  (f) thereof;  (ii) adding the
word  "and"  at the end of  subsection  (g)  thereof);  and  (ii)  adding  a new
subsection (h) to follow subsection (g) thereof to read as follows:

               "(h)   additional   unsecured   indebtedness   in  an   aggregate
          outstanding  principal  amount not to exceed $500,000 at any time and,
          to the extent  such  indebtedness  is incurred  by a  Subsidiary,  the
          guarantee by the Borrower of such indebtedness."

          (b) Subsection  7.04(f) of the Credit  Agreement  shall be amended and
restated in its entirety so as to read as follows:

               "(f)  employee  relocation  loans made in the ordinary  course of
          business in an aggregate  outstanding  principal  amount not to exceed
          $500,000 at any time."

     3.  Representations  and  Warranties.  The Borrower  hereby  represents and
warrants to the Bank as follows:

          (a) No Default or Event of Default has occurred and is continuing.
<PAGE>
          (b) The  execution,  delivery and  performance by the Borrower of this
Amendment have been duly authorized by all necessary  corporate and other action
and do not and will not require any registration  with,  consent or approval of,
notice to or action by, any Person  (including  any  governmental  authority) in
order to be effective and  enforceable.  The Credit Agreement as amended by this
Amendment  constitutes the legal, valid and binding obligations of the Borrower,
enforceable against it in accordance with its respective terms, without defense,
counterclaim or offset.

          (c) All  representations  and warranties of the Borrower  contained in
the Credit Agreement are true and correct as of the date hereof.

          (d) The Borrower is entering  into this  Amendment on the basis of its
own investigation and for its own reasons, without reliance upon the Bank or any
other Person.

     4.  Reservation of Rights.  The Borrower  acknowledges  and agrees that the
execution  and  delivery  by the Bank of this  Amendment  shall not be deemed to
create a course of dealing or  otherwise  obligate  the Bank to execute  similar
amendments under the same or similar circumstances in the future.

     5. Miscellaneous.

          (a)  Except as herein  expressly  amended,  all terms,  covenants  and
provisions of the Credit Agreement are and shall remain in full force and effect
and all references  therein to such Credit  Agreement shall  henceforth refer to
the Credit  Agreement  as amended by this  Amendment.  This  Amendment  shall be
deemed incorporated into, and a part of, the Credit Agreement.

          (b) This  Amendment  shall be binding upon and inure to the benefit of
the parties hereto and thereto and their respective  successors and assigns.  No
third party beneficiaries are intended in connection with this Amendment.

          (c) This  Amendment  shall be governed by and  construed in accordance
with the law of the State of California.

          (d) This Amendment may be executed in any number of counterparts, each

constitute  but  one  and  the  same  instrument.  Each  of the  parties  hereto
understands  and agrees that this document may be delivered by any party thereto
either in the form of an  executed  original  or an  executed  original  sent by
facsimile  transmission  to be  followed  promptly  by  mailing  of a hard  copy
original,  and that  receipt  by the Bank of a  facsimile  transmitted  document
purportedly  bearing the signature of the Borrower  shall bind the Borrower with
the same force and effect as the delivery of a hard copy  original.  Any failure
by the Bank to receive the hard copy executed  original of such  document  shall
not diminish the binding effect of receipt of the facsimile
                                        2
<PAGE>
transmitted  executed  original  of such  document  which hard copy page was not
received by the Bank.

          (e) This Amendment,  together with the Credit Agreement,  contains the
entire and  exclusive  agreement  of the parties  hereto with  reference  to the
matters discussed herein and therein. This Amendment supersedes all prior drafts
and  communications  with respect  thereto.  This  Amendment  may not be amended
except  in  accordance  with  the  provisions  of  Section  9.05  of the  Credit
Agreement.

          (f) If any  term  or  provision  of this  Amendment  shall  be  deemed
prohibited  by or invalid under any  applicable  law,  such  provision  shall be
invalidated without affecting the remaining  provisions of this Amendment or the
Credit Agreement, respectively.

          (g) The  Borrower  covenants  to pay to or  reimburse  the Bank,  upon
demand, for all reasonable costs and expenses  (including  reasonable  allocated
costs  of  in-house  counsel)  incurred  in  connection  with  the  development,
preparation, negotiation, execution and delivery of this Amendment.

          IN WITNESS  WHEREOF,  the parties  hereto have  executed and delivered
this Amendment as of the date first above written.

                                   EXHIBIT 99

                Private Securities Litigation Reform Act of 1995
         Safe Harbor Compliance Statement for Forward-Looking Statements

         In passing the Private  Securities  Litigation  Reform Act of 1995 (the
"PSLRA"),   Congress  encouraged  public  companies  to  make   "forward-looking
statements"1 by creating a safe-harbor to protect  companies from securities law
liability in connection with forward-looking  statements.  Microtest,  Inc. (the
"Company"  or  "Microtest")  intends  to  qualify  both  its  written  and  oral
forward-looking statements for protection under the PSLRA.

         To qualify oral  forward-looking  statements for  protection  under the
PSLRA, a readily available written document must identify important factors that
could   cause   actual   results  to  differ   materially   from  those  in  the
forward-looking  statements.  Microtest  provides the following  information  in
connection with its continuing effort to qualify forward-looking  statements for
the safe harbor protection of the PSLRA.

         Important factors currently known to management that could cause actual
results to differ materially from those in forward-looking  statements  include,
but are not limited to, the following:  (I) changes in the Company's product and
customer  mix;  (ii)  introduction  of  new  products  by  the  Company  or  its
competitors;  (iii)  pricing  pressures  and economic  conditions  in the United
States and Europe;  (iv) the economic  condition of the computer  industry;  (v)
failure of the Company to continue  to enhance its current  product  line and to
continue to develop and introduce  new products that keep pace with  competitive
product introductions and technological  advances,  satisfy diverse and evolving
customer requirements,  or otherwise achieve market acceptance;  (vi) loss of or
reduction in purchases by certain of the Company's  distributors and VARs; (vii)
any reduction in sales of the Company's  PentaScanner or DiscPort  products from
which the Company derives substantially all of its revenue; (viii) the inability
of the Company to  accurately  monitor end user  demand for its  products;  (ix)
unanticipated  product  returns to the extent such returns  exceed the Company's
reserves;  (x) the cost, quality and availability of third-party components used
in the  Company's  systems;  (xi) the loss of any of the  Company's  third-party
manufacturers or key suppliers;  (xii) any disruption or reduction in the future
supply of key components currently obtained from limited sources; (xiii) defects
in the Company's  products that could cause delays in product  introductions and
shipments,  cause loss of or delays in market  acceptance,  result in  increased
costs,  require design  modifications  or impair  customer  satisfaction;  (xiv)
inventory  writedowns,  product returns or price protection  credits that exceed
the  Company's  estimates;  (xv) the  inability  of the  Company  to expand  its
international operations in a timely and cost effective manner, as well as other
risks in  conducting  business  internationally;  (xvi)  recruiting,  hiring and
retaining the services of key engineering,  sales and marketing,  management and
manufacturing  personnel;  (xvii)  the  failure of the  Company  to protect  its
proprietary information and technology; and (xviii) the inability of the Company
to collect a significant amount of the outstanding accounts receivable.

- ----------------------
1  "Forward-looking  statements"  can be  identified  by use of  words  such  as
"expect," "believe," "estimate,"  "project,"  "forecast,"  "anticipate," "plan,"
and similar expressions.
                                       15
<PAGE>
         Forward-looking  statements express  expectations of future events. All
forward-looking statements are inherently uncertain as they are based on various
expectations  and assumptions  concerning  future events and they are subject to
numerous  known and unknown  risks and  uncertainties  which could cause  actual
events or  results  to differ  materially  from  those  projected.  Due to these
inherent  uncertainties,  the  investment  community is urged not to place undue
reliance on forward-looking  statements.  In addition,  Microtest  undertakes no
obligation to update or revise  forward-looking  statements  to reflect  changed
assumptions,  the occurrence of  unanticipated  events or changes to projections
over time.
