              Notes to Condensed Consolidated Financial Statements
                         July 31, 1998 and July 31,1997
                                   (Unaudited)

1.      General

       The financial statements have been prepared without audit.  However, they
       reflect all adjustments  which in the opinion of management are necessary
       to fairly  state the  Company's  financial  position at July 31, 1998 and
       January 31, 1998,  the results of its  operations  for the quarters ended
       and two  quarters  ended July 31,  1998 and July 31,  1997,  and its cash
       flows for the two  quarters  ended July 31, 1998 and July 31,  1997.  The
       information has been prepared in accordance with Form 10-Q  instructions,
       but does not necessarily  include all information and footnotes  required
       by  generally  accepted  accounting  principles  for  complete  financial
       statements.  The results of the quarter ended and two quarters ended July
       31, 1998 are not necessarily indicative of the results to be obtained for
       the full fiscal year.


2.     Intellectual Property Acquisition

       In May 1998, the Company completed the purchase of intellectual  property
       and related software assets from Industrial Technology, Inc. The acquired
       technology  includes  software  suited for  automating  the comparison of
       digital  speech  quality over diverse  cellular,  PCS, and other wireless
       networks. No tangible assets were acquired. The Company has accounted for
       the purchase price as an intangible asset.


3.     Significant Accounting Policies - Per Share Information

       During the year ended January 31, 1998, the Company adopted  Statement of
       Financial  Accounting Standards No. 128, Earnings per Share, and computed
       basic and  diluted  net income per share  based on the  weighted  average
       number of shares of common stock and potential  common stock  outstanding
       during the period.  Potential  common stock,  for purposes of determining
       diluted  earnings  per share,  includes  the  effects of  dilutive  stock
       options.  The effect of such potential common stock is computed using the
       treasury  stock  method.  Comparative  earnings  per share data have been
       restated for prior periods.  Consolidated  net income of the Company used
       for diluted  earnings per share  purposes is diluted as a result of stock
       options issued by the Company's  subsidiaries  which enable their holders
       to obtain the  subsidiaries'  common stock.  Basic and diluted net income
       per share are calculated as follows:

ITEM 2.       MANAGEMENT'S  DISCUSSIO  AND ANALYSIS OF RESULTS OF OPERATIONS AND
              FINANCIAL CONDITION


              Except  for  the  historical  information  contained  herein,  the
              matters discussed in this Form 10-Q are forward-looking statements
              within the meaning of Section 21E of the  Securities  Exchange Act
              of 1934,  as amended,  and Section  27A of the  Securities  Act of
              1933, as amended, that involve risks and uncertainties. The actual
              results that the Company  achieves may differ  materially from any
              forward-looking  projections due to such risks and  uncertainties.
              Words  such as  "believes,"  "anticipates,"  "expects,"  "future,"
              "intends,"  and  similar  expressions  are  intended  to  identify
              forward-looking  statements  but are not the  exclusive  means  of
              identifying  such  statements.   A  more  complete  discussion  of
              business risks is included in the Company's  Annual Report on Form
              10-K for the year ended January 31, 1998.


       (a)    Results of Operations

              During the second quarter of Fiscal Year 1999 (year ending January
              31, 1999),  the Company  recorded total revenues of $22.0 million,
              up 4.8% from the  revenues  of $21.0  million  for the  comparable
              period  of the  prior  fiscal  year.  Revenues  for the  first two
              quarters  of Fiscal  Year 1999 of $43.8  million  are up 6.6% from
              $41.1 million for the comparable  period of the prior fiscal year.
              Increased year-to-year revenues are primarily due to:
                 o sales of the Company's wireless communications products;
                 o increase in information technology services activity of 15%
                   year-to-year;
              partially offset by:
                 o reduced activity on the Company's contract at the Los Angeles
                   County Airports.

              Total  direct  costs of $13.0  million  for the second  quarter of
              Fiscal Year 1999 are up $.3 million,  or 2.4%,  from $12.7 million
              for the second  quarter of Fiscal Year 1998.  Direct costs for the
              first two  quarters  of Fiscal  Year 1999 of $26.3  million are up
              $1.7  million,  or 6.9%,  from $24.6  million  for the  comparable
              period of the  prior  fiscal  year.  The  increases  relate to the
              increased  revenue  activity,   particularly  from  the  Company's
              wireless  communications  products business (as discussed below in
              the wireless communications products section).

              Total  indirect  costs of $7.0  million for the second  quarter of
              Fiscal Year 1999 are up $.7 million,  or 11.1%,  from $6.3 million
              for the second quarter of Fiscal Year 1998. Indirect costs for the
              first two  quarters  of Fiscal  Year 1999 of $14.3  million are up
              $1.4  million,  or 10.9%,  from $12.9  million for the  comparable
              period of the prior fiscal year.  The  increases  are  principally
              from the Company's wireless  communications products business, and
              results from  increased  product  development  costs and increased
              selling,  general and  administrative  costs, as further discussed
              below.

              Net interest income  (interest  income less interest  expense) for
              the second  quarter of Fiscal Year 1999  amounted  to $95,000,  as
              compared to $121,000 for the comparable period of the prior fiscal
              year.  Net  interest  income for the first two  quarters of Fiscal
              Year 1999  amounted to  $213,000,  as compared to $256,000 for the
              comparable  period of the prior fiscal  year.  The  decreases  are
              principally due to a reduction in cash available to invest from an
              average of $13  million in the first two  quarters  of Fiscal Year
              1998 to an average of $10  million  in the first two  quarters  of
              Fiscal Year 1999.

              The  Company's  effective  tax rate for the first two  quarters of
              Fiscal Year 1998 is 38%, the same as the comparable  period of the
              prior fiscal year.

              Net income of $1.3  million for the second  quarter of Fiscal Year
              1999 is unchanged  from the  comparable  period of the prior year.
              Net income of $2.1  million  for the first two  quarters of Fiscal
              Year 1999 is down from $2.4 million for the  comparable  period of
              the  prior  year  due to the  increased  product  development  and
              selling,   general  and  administrative  costs  incurred  for  the
              wireless  communications  products business,  as further discussed
              below.


              Wireless Communications Products

              Wireless  communications  products revenues increased 4.2% to $7.4
              million  for the  second  quarter  of  Fiscal  Year 1999 from $7.1
              million  for the  comparable  period  of the  prior  fiscal  year.
              Revenues  increased  12.2%  to $14.7  million  for the  first  two
              quarters of Fiscal Year 1999 from $13.1 million for the comparable
              period of the prior fiscal year. This increase is due to increased
              sales  of  the  Company's   emergency  callbox  systems.   Summary
              operating  results for Comarco  Wireless  Technologies,  Inc., the
              Company's  wireless  communications  products  subsidiary,  are as
              follows:

              *Indirect  costs  include  selling,   general  and  administrative
              expenses as well as research and development expenses.
</TABLE>
              The decreased  gross income  percentage is due to greater sales of
              the Company's  emergency  callbox systems,  which have lower gross
              margins than the field  measurement and revenue  assurance product
              families,  whose revenues were relatively unchanged  year-to-year.
              The Company  believes  that  product  sales  other than  emergency
              callbox  systems may not  increase  over the prior  period for the
              third  quarter of Fiscal  Year  1999,  while  comparisons  for the
              fourth  quarter  of  Fiscal  Year  1999  are  expected  to be more
              favorable due to anticipated upgraded product offerings,  although
              there can be no assurances in this regard.

              The  increase in  indirect  costs of $.7 million for the first two
              quarters  of Fiscal  Year 1999 over the  comparable  period of the
              prior  fiscal  year is  principally  a result of  increased  costs
              incurred in the Company's product development  program, as well as
              increased selling,  general and administrative  costs.  Sustaining
              engineering  and research and development  expenses  increased 25%
              year-to-year,  while selling,  general and administrative expenses
              increased 8.3% year-to-year.

              Operating  income as a  percentage  of  revenues  is 20.2% for the
              second  quarter  of Fiscal  Year 1999,  compared  to 24.3% for the
              comparable period of the prior fiscal year.  Operating income as a
              percentage  of  revenues  is 14.5% for the first two  quarters  of
              Fiscal Year 1999,  compared to 21.7% for the comparable  period of
              the prior fiscal year.  These  decreases  are primarily due to the
              lower  gross  income  due to a  larger  mix of  the  lower  margin
              emergency  callbox  systems  than in the  prior  year's  first two
              quarters, as discussed above.

              The Company is continuing its product  development  program in its
              wireless  communications  products  business.  In accordance  with
              Financial  Accounting Standard No. 86, Accounting for the Costs of
              Computer Software to be Sold, Leased, or Otherwise  Marketed,  the
              Company  capitalized  $1,579,000  and  $1,266,000,   respectively,
              during  the first two  quarters  of  Fiscal  Years  1999 and 1998,
              respectively.  Corresponding  amounts  amortized were $721,000 and
              $644,000, respectively.

              In May 1998,  the Company  completed the purchase of  intellectual
              property and related  software assets from Industrial  Technology,
              Inc.  The  acquired   technology   includes  software  suited  for
              automating  the  comparison of digital speech quality over diverse
              cellular, PCS, and other wireless networks. The Company intends to
              use the  acquired  technology  to enhance its  network  evaluation
              family of products.

              The Company's  future wireless  products  prospects will depend in
              part on its ability to enhance the  functionality  of its existing
              products in a timely and  cost-effective  manner and to  identify,
              develop, and achieve market acceptance of new products.  There can
              be no  assurance  that  the  Company  will be able to  respond  to
              technological  advances,  changes  in  customer  requirements,  or
              changes in regulatory requirements or industry standards,  and any
              significant  delays in  development,  introduction  or shipment of
              products, or achievement of acceptable product costs, could have a
              material  adverse  effect  on the  Company's  business,  operating
              results and financial condition.

              The Company's orders for wireless communications products totalled
              $7.4 million for the second  quarter of Fiscal Year 1999,  up from
              $6.1  million  from  the   comparable   prior   period.   For  the
              twelve-month periods ended July 31, 1998 and 1997, orders received
              were $28.0 million and $36.5  million,  respectively.  Included in
              the  amount  for the twelve  months  ended  July 31,  1997 was $10
              million of long-term  maintenance service business associated with
              the purchase of the GTE callbox product line.  Because of the long
              sales cycle  involved in selling the Company's  wireless  products
              and the high unit sales price,  the Company  believes  that orders
              are best  analyzed by looking at a twelve  month time  period,  as
              orders can fluctuate  significantly  from quarter to quarter.  The
              value of unfilled  orders at July 31, 1998 totalled $15.7 million,
              of which $7.4 million relates to long-term maintenance  contracts,
              and $3.7 million relates to the Company's  contract to upgrade the
              Los Angeles  County  callbox  system to comply with the  Americans
              with Disabilities Act's requirements for use by hearing and speech
              impaired  individuals.  The Company currently expects the majority
              of the Los Angeles  County  contract to be performed at the end of
              Fiscal  Year 1999 and into Fiscal Year 2000.  An  additional  $1.6
              million of deferred  revenue  has been  recorded  for  anticipated
              customer warranty obligations.

              The   Company   has    experienced    fluctuations   in   wireless
              communications  products  activity in each of the past four years,
              with  greater  sales in the  second  half of its  fiscal  year and
              lesser  amounts in the first  half,  although  this trend has been
              declining  over the same  four  years.  This  trend may or may not
              continue as the Company broadens its product offerings. The nature
              of the wireless  communications  products  business is  inherently
              unpredictable;  sales and profits may fluctuate significantly from
              quarter to quarter; and therefore, period-to-period comparisons of
              its  operating  results are not  necessarily  meaningful  and such
              comparisons   cannot  be  relied  upon  as  indicators  of  future
              performance.

              The  Company  faces  additional  risk  factors in  developing  its
              wireless  communications  products  business,  including:  foreign
              marketing,    capital   requirements,    technical   requirements,
              employees,  competition,  and proprietary information.  A negative
              impact to any of these risk factors could have a material  adverse
              effect on the Company's business, operating results, and financial
              condition.  Foreign  marketing risks include:  the need for export
              licenses; tariffs and other potential trade restrictions;  changes
              in laws  governing the  imposition of duties,  quotas,  taxes,  or
              other  charges  relating to the import or export of its  products;
              and changes in foreign  currency  exchange  rates which can impact
              customers' demand for the Company's  products and their ability to
              pay for the Company's products.  Other companies having a presence
              or doing business overseas may have advantages over the Company in
              these  areas.  Certain  components  used  by  the  Company  in its
              existing  products are only  available  from a single or a limited
              number of suppliers,  and the inability by any of these  suppliers
              to fulfill Company  requirements  may result in an interruption in
              production. Access to technical design of air interface devices is
              essential  for the Company to  anticipate  and develop  compatible
              wireless  communications  products;  therefore,  the  inability to
              obtain  such  technical  designs  on a timely  basis  would have a
              direct impact on product design and schedule. The Company's future
              success also depends in large part on the continued service of its
              key  personnel,  and on its  ability to  continue  to attract  and
              retain qualified  employees,  especially highly skilled engineers,
              for whom competition in the industry is intense. In addition,  the
              ability  of the  Company to compete  successfully  depends  upon a
              number of factors,  including the rate at which  customers  accept
              the Company's  products in overseas  markets,  product quality and
              performance,  experienced  sales and  marketing  personnel,  rapid
              development  of  new  products  and  features,  evolving  industry
              standards, and the number and nature of the Company's competitors.
              There can be no assurance that the Company will be able to compete
              successfully in the future. The Company relies on a combination of
              trade secrets,  copyrights,  and contractual rights to protect its
              intellectual  property.  There can be no assurance  that the steps
              taken by the Company  will be adequate to protect its  technology;
              in addition,  the laws of certain  foreign  countries in which the
              Company's  products  may be  sold  do not  protect  the  Company's
              intellectual  property rights to the same extent as do the laws of
              the United States.


              Information Technology and Staffing Services Revenue

              Revenues  provided by the  Company's  information  technology  and
              staffing services business area increased 5.0%, from $13.9 million
              in the second  quarter of Fiscal Year 1998 to $14.6 million in the
              second  quarter of Fiscal Year 1999.  Revenues  from this business
              area increased 3.9%, from $28.0 million for the first two quarters
              of Fiscal Year 1998 to $29.1 million for the first two quarters of
              Fiscal Year 1999.  Revenues in this business area  decreased  from
              68.1% of the Company's total revenues in the first two quarters of
              Fiscal Year 1998 to 66.4% of the Company's  total  revenues in the
              first  two   quarters  of  Fiscal  Year  1999.   The  increase  in
              period-to-period  revenue  is due to an  increase  in  information
              technology services activity on contracts with the U.S. Government
              partially  offset  by a  decrease  in  activity  on the  Company's
              management services contract at the Los Angeles County Airports.

              Sales  to the  U.S.  Government  as  well as to  government  prime
              contractors were 33% and 34% of the Company's total revenue during
              the  first  two   quarters   of  Fiscal   Years   1998  and  1999,
              respectively.  In  the  course  of  the  Company's  business,  its
              contracts with customers are periodically  opened for competition.
              In March 1998, the Company  announced the award of a contract with
              an award value of $75  million to continue to provide  engineering
              and management  services to the U.S. Navy at Crane,  Indiana.  The
              Company's   management  services  contract  at  Reagan  Washington
              National  Airport ends on September 30, 1998.  The Company did not
              pursue the  recompete of this  contract.  This  contract's  annual
              revenues   approximate  $8.8  million,   it  has  been  marginally
              profitable,  and it  would be  unprofitable  if  reawarded  to the
              Company.  Two other multi-year  government contracts are scheduled
              to end in Fiscal Year 1999 with annual  revenues of  approximately
              $3.8 million.  The Company plans to aggressively  compete for work
              opened for  competition to the extent  possible and to selectively
              pursue certain high value contract  procurements.  There can be no
              assurance  that the Company  will be selected and awarded the work
              associated  with  any  of  its  future  proposals.   In  addition,
              government  agencies may terminate  their contracts in whole or in
              part at their convenience.  Government agencies may remove funding
              previously provided or may not exercise option periods. Therefore,
              there  can be no  assurance  that  the  Government  will  fund the
              portions  of existing  contracts  that are  unfunded,  or that the
              governmental agencies will exercise any options.

              Operating income (revenues less direct costs,  indirect costs, and
              depreciation  and  amortization)  for  information  technology and
              staffing  services is up from  $288,000  in the second  quarter of
              Fiscal Year 1998 to $489,000 in the second  quarter of Fiscal Year
              1999.  Operating  income for  information  technology and staffing
              services is up from  $811,000 in the first two  quarters of Fiscal
              Year 1998 to  $1,077,000  in the first two quarters of Fiscal Year
              1999.  The  increase  is  primarily  due to  higher  revenues  for
              information technology and airport management services,  partially
              offset by lower operating  income from commercial  staffing due to
              the cost of opening additional offices.


       (b)    Financial Condition

              The  Company  signed  a  loan  agreement  with  a  bank  effective
              September 26, 1994,  which was amended  effective August 21, 1998.
              The loan  agreement  consists  of a $10 million  revolving  credit
              facility,  which  expires  June 30, 2000.  The credit  facility is
              unsecured  provided that the Company maintains certain  covenants.
              Currently,  management anticipates that cash flow will remain at a
              level which will enable the Company to avoid  utilizing the credit
              facility  except to  support  letters  of credit  and  acquisition
              financing,   and  that  the  Company  will  be  able  to  purchase
              investments on a regular basis.  The Company's cash and investment
              balances  averaged $10 million  (includes  highly liquid long-term
              investments  with  maturities of 12 to 36 months) during the first
              two quarters of Fiscal Year 1999.  However,  maintaining such cash
              balances is  predicated  on the Company  maintaining  its business
              base  and is  subject  to the  cost of  financing  new  contracts,
              acquisitions, geographic expansion, product development costs, and
              stock re-purchases.

              During the first two quarters of Fiscal Year 1999,  the  Company's
              average  days'  sales  in  accounts   receivable   have  increased
              slightly,   primarily   due  to   increased   sales  of   wireless
              communications products, which have a longer collection cycle than
              the Company's information technology and staffing revenues.

              Several additional key factors indicating the Company's  financial
              condition include:

                  Current ratio                            2.99                   2.75
                  Working capital                 $  21,504,000        $    20,937,000
                  Book value per share                    $6.81                  $6.46
</TABLE>


              The Company continued to demonstrate  solid financial  strength in
              the above  financial  factors  during  the first two  quarters  of
              Fiscal Year 1999 due to continued profitable activity.

              The Company has a significant  commitment for capital expenditures
              at July 31,  1998 for  Comarco  Wireless  Technologies,  Inc.  The
              Company  has  developed  and  intends to  continue  to develop new
              product line extensions for the wireless communications  industry.
              This product development program is expected to be funded from the
              Company's  current working  capital.  The amounts  capitalized and
              amortized  in  the  Company's  wireless   communications  products
              business in accordance with Financial  Accounting Standard No. 86,
              Accounting for the Costs of Computer Software to be Sold,  Leased,
              or  Otherwise   Marketed,   totaled   $1,579,000   and   $721,000,
              respectively, in the first two quarters of Fiscal Year 1999.

              The  Company's   Board  of  Directors   has   authorized  a  stock
              re-purchase  program  of up to  1,500,000  shares.  As of July 31,
              1998,  the Company  has  re-purchased  and  retired  approximately
              966,000  shares.  The  average  price paid per share  re-purchased
              under the  program was $7.06.  An  additional  92,000  shares were
              repurchased  during August 1998 for approximately  $1.8 million at
              an average price of $19.59 per share.

              The Company is subject to legal  proceedings and claims that arise
              in the ordinary course of business.  In the opinion of management,
              the amount of ultimate  liability  with  respect to these  actions
              will not materially affect the financial condition of the Company.

              The  Company  believes  that its cash  flow  from  operations  and
              available  bank  borrowings  will be  sufficient  to  satisfy  the
              current and anticipated capital requirements for operations.


              Impact of the Year 2000 Issue

              Many computer  systems and software  products  currently in use by
              businesses  and government  organizations  are coded to accept two
              digits,  rather  than four,  to specify  the year.  Such  computer
              systems and software products will be unable to properly interpret
              dates  beyond  the  year  1999,   which  could  lead  to  business
              disruptions  (the "Year 2000  Issue").  As a result,  in less than
              sixteen  months,  computer  systems  and/or  software used by many
              companies  may need to be  upgraded to  properly  interpret  dates
              beyond 1999. The Company's  technical personnel are in the process
              of  assessing  the impact of the Year 2000 Issue on the  Company's
              products and services.

              The Company has established a two-phase program to ensure that its
              proprietary  software and internal  computer systems are Year 2000
              compliant.  The initial phase, which included planning,  inventory
              and assessment, has been substantially completed. The final phase,
              which consists of correction,  testing, deployment and acceptance,
              is in process and is expected to be  completed  by  mid-1999.  The
              Company expects that the cost of making its  proprietary  software
              and internal systems  compliant will not have a material effect on
              its overall financial position or results of operations.

              The Company is also beginning the same two-phase program to assess
              the risks to the Company of non-IT systems. Non-IT systems include
              embedded technology such as  micro-controllers.  The initial phase
              is planned to be completed by the end of 1998 with the final phase
              completed during 1999. Based on a preliminary assessment, the cost
              of non-IT systems  remediation  will not have a material impact on
              the Company.

              The Company has initiated formal  communications  with its crucial
              suppliers  to  determine  whether  they  are or will be Year  2000
              capable.  By mid-1999,  the Company expects to have identified and
              develop  contingency  plans for any such suppliers who will not be
              year 2000 ready.

              The  Company  has also  been  working  with its  customers  and is
              completing an assessment of its  obligations to make their systems
              Year  2000  ready.  The  Company  currently  believes  that  these
              obligations will not have a material effect on the Company.

              Even with the  effort to  address  the Year 2000 Issue made by the
              Company to date,  there can be no  assurance  that the  systems of
              other  entities  on  which  the  Company  relies  will  be  timely
              remediated,  or that a failure to  remediate  by  another  entity,
              would not have a material adverse effect on the Company.

              The Company will utilize both  internal and external  resources to
              reprogram,   or  replace,   and  test   software   for  Year  2000
              modifications.  The  total  cost of the  program  is being  funded
              through  operating cash flows.  The total cost associated with the
              required  modifications  and  conversions  is not  expected  to be
              material to the Company's  consolidated  results of operations and
              financial position.

PART II - OTHER INFORMATION

ITEM 5.       OTHER INFORMATION

              The  Securities  and Exchange  Commission  has amended Rule 14a-4,
              which governs the use of discretionary proxy voting authority with
              respect to a  shareholder  proposal that the  shareholder  has not
              sought to include in the proxy  statement  pursuant to Rule 14a-8.
              Rule 14a-4(c)(1) now sets a 45 day advance notice requirement.  If
              a shareholder  fails to notify the Company of his or her intention
              to present a proposal at the meeting at least 45 days prior to the
              month and day on which the prior year's proxy  statement was first
              mailed,  then the  holders  of proxies  solicited  by the Board of
              Directors may use their  discretionary  voting  authority when the
              proposal  is raised at the  Company's  Annual  Meeting.  The proxy
              holders will have such  discretionary  authority even if the proxy
              statement  contained no  discussion  of the proposal and the proxy
              holders' intentions with respect thereto.

              In the case of COMARCO,  Inc.,  April 5, 1999 is the  deadline for
              shareholders  to give such notice with respect to a proposal  that
              is not sought to be included in the Company's proxy statement with
              respect  to the 1999  Annual  Meeting.  As has been the case,  any
              shareholder  who  wishes  to  have  a  proposal  included  in  the
              Company's  proxy  statement for its 1999 Annual  Meeting (which in
              all cases  will be  subject to the rules  regarding  whether  such
              proposal may be excluded notwithstanding the request), must notify
              COMARCO pursuant to Rule 14-8 not later than January 21, 1999.

                      -----------------------------------
                           
         THIS FOURTH  AMENDMENT TO LOAN AGREEMENT (this  "Agreement")  made this
21st  day  of  August,  1998  by and  among  (i)  COMARCO,  INC.,  a  California

Delaware  corporation,  INTERNATIONAL  BUSINESS  SERVICES,  INC.,  a District of
Columbia  corporation,  DECISIONS AND DESIGNS,  INC., a Virginia corporation and

and CWI,  together with the Original  Guarantors,  being  individually  called a
"Guarantor"  and  collectively,  the  "Guarantors")  and  NATIONSBANK,  N.A.,  a
national banking association, its successors and assigns (the "Bank").

                                    RECITALS
                                    --------

         A. The Borrower, the Original Guarantors and the Bank have entered into
that  certain  Loan  Agreement  dated  September  26, 1994 (the  "Original  Loan
Agreement"),  which  Original  Loan  Agreement was amended by that certain First
Amendment to Loan Agreement dated September 26, 1995, by and among the Borrower,
the Original  Guarantors  and the Bank,  and which  Original Loan  Agreement was
further amended by that certain Second  Amendment to Loan Agreement dated August
30, 1996 by and among the Borrower, the Original Guarantors,  MTTCI, CSI and the
Bank.  Comarco  Systems and CWI were added as  guarantors  to the Original  Loan
Agreement pursuant to that certain Third Amendment to Loan Agreement dated as of
August 15, 1997 by and among the Borrower,  the  Guarantors  and the Bank.  (The
Original Loan Agreement,  as thereafter  amended from time to time, is hereafter
called the "Loan Agreement").
         B.  The  Borrower  and the  Guarantors  have  requested  that  the Bank
consolidate  the Master  Line of Credit and the  Guidance  Line of Credit into a
single  Master  Line of Credit in the  maximum  principal  amount of Ten Million
Dollars   ($10,000,000)  to  be  used  by  the  Borrower  for  working  capital,
acquisitions and the other purposes  described  herein,  and the Bank has agreed
subject to the terms of this Agreement.
         C. All  capitalized  terms used herein and not otherwise  defined shall
have the meanings given to such terms in the Loan Agreement.
         NOW, THEREFORE, in consideration of the premises, the mutual agreements
herein  contained,  and other good and valuable  consideration,  the receipt and
sufficiency of which are hereby acknowledged,  the Borrower,  the Guarantors and
the Bank hereby agree as follows:

         1. Recitals.  The parties hereto  acknowledge  and agree that the above
Recitals are true and correct in all respect and that the same are  incorporated
herein and made a part hereof by reference.

         2.  Definitions.  The definitions of "Loans",  "Master Line of Credit",
"Master  Line of Credit  Expiration  Date" and  "Notes"in  Article I of the Loan
Agreement are amended and restated in their entirety as follows

                  "Loans"  shall  mean  the  Master  Line of  Credit  (including
         acquisition loans made pursuant thereto).

                  "Master  Line of Credit"  shall  mean the line of  credit/term
         loan facility  granted to the Borrower  pursuant to this Agreement,  in
         the maximum principal amount of Ten Million Dollars ($10,000,000) or so
         much thereof as shall be advanced or re-advanced  and from time to time
         remain  unpaid,  as evidenced by the Master Line of Credit Note and the
         Acquisition Term Notes.

                  "Master Line of Credit Commitment  Expiration Date" shall mean
July 30, 2000.

                  "Notes"  shall  mean the  Master  Line of Credit  Note and all
Acquisition Term Notes, collectively.  From and after the effective date hereof,
the Loan Agreement  shall be interpreted  and construed to delete all references
to the Guidance Line of Credit and the Guidance Line of Credit Note.

         3. Commitment. From and after the effective date hereof, paragraph 1 of
Article II of the Loan  Agreement is hereby amended and restated in its entirety
as follows:
                  1. Commitment. Subject to and upon the terms and conditions of
         this  Agreement,  the Bank  agrees  that it will  extend  credit to the
         Borrower  for the  purposes  and in the  amounts  set  forth  herein as
         follows:

                           (a) Master Line of Credit.  The Bank shall  extend to
         the Borrower  the Master Line of Credit,  which shall be in the maximum
         principal  amount  of Ten  Million  Dollars  ($10,000,000),  or so much
         thereof as may be advanced or  readvanced  and from time to time remain
         unpaid,  and bear interest and be payable in accordance  with the terms
         of (i) a Fourth Amended and Restated  Master Line of Credit Note in the
         maximum principal amount of Ten Million Dollars  ($10,000,000) dated as
         of July 31, 1998 (together with all renewals, extensions, modifications
         and  substitutions  thereof or  therefor,  the  "Master  Line of Credit
         Note");  and (ii) any term notes  (each,  together  with all  renewals,
         extensions,  modifications and substitutions thereof or therefor, being
         herein  referred  to  as  an  "Acquisition  Term  Note")  executed  and
         delivered by the Borrower in  connection  with advances made by the Ban
         for acquisitions as herein  provided.  It is understood and agreed that
         the maximum  principal amount of availability  under the Master Line of
         Credit shall be reduced by the maximum principal amount of availability
         of any  Acquisition  Term  Notes  issued  pursuant  to this  Agreement,
         simultaneously  and automatically upon issuance of any Acquisition Term
         Note(s).  The  forms  of  the  Master  Line  of  Credit  Note  and  the
         Acquisition Term Note to be utilized are attached hereto as Exhibit B-1
         and B-2, respectively.

         4. Use of Loan Proceeds. In addition to the permitted uses described in
paragraph 2(a) of Article II of the Loan  Agreement,  the proceeds of the Master
Line of Credit may be used in connection with Exchange Contracts (as hereinafter
defined)  and the  issuance of Letters of Credit in the  ordinary  course of the
Borrower's  business;  provided,  however,  in no  event  whatsoever  shall  the
aggregate  face  amount of all such  Letters of Credit  outstanding  at any time
exceed Two Million Dollars ($2,000,000).

         5.  Foreign  Exchange.  Subject  to the  terms of this  Agreement,  the
Borrower may enter into foreign  exchange  contracts (the "Exchange  Contracts")
not to exceed an aggregate amount of $750,000 (the "Contract  Limit"),  pursuant
to which the Bank shall sell to or purchase from the Borrower  foreign  currency
on a spot or future basis. The Borrower shall not request any Exchange Contracts
at any time it is out of compliance with any of the provisions of this Agreement
or the Loan  Agreement.  All  Exchange  Contracts  must  provide for delivery of
settlement  on or before June 30, 2000.  The amount  available  under the Master
Line of  Credit at any time  shall be  reduced  by the  following  amounts  (the
"Foreign Exchange Reserve") on any given day (the "Determination  Date"): (i) on
all  outstanding  Exchange  Contracts  on which  delivery  is to be  effected or
settlement allowed more than two (2) Business Days after the Determination Date,
ten percent  (10%) of the gross amount of the Exchange  Contracts;  plus (ii) on
all  outstanding  Exchange  Contracts  on which  delivery  is to be  effected or
settlement  allowed within two (2) Business Days after the  Determination  Date,
one hundred percent (100%) of the gross amount of the Exchange Contracts.

         The Bank may, in its  discretion,  terminate the Exchange  Contracts at
any time (a) that an Event of Default  occurs or (b) that there is no sufficient
availability  under the  Master  Line of Credit and the  Borrower  does not have
available funds in its bank account to satisfy the Foreign Exchange Reserve.  If
the Bank  terminates  the  Exchange  Contracts,  and without  limitation  of any
applicable  indemnities,  the Borrower  agrees to reimburse the Bank for any and
all  fees,  costs  and  expenses  relating  thereto  or  arising  in  connection
therewith.

         The  Borrower  shall not permit the total gross  amount of all Exchange
Contracts on which delivery is to be effected and settlement  allowed in any two
(2) Business Day period to be more than  $750,000 (the  "Settlement  Limit") nor
shall the Borrower  permit the total gross  amount of all Exchange  Contracts to
which  the  Borrower  is a party,  outstanding  at any one time,  to exceed  the
Contract  Limit.  Notwithstanding  the above,  however,  the amount which may be
settled in any two (2) Business Day period may be increased above the Settlement
Limit up to, but in no event to exceed,  the amount of the Contract  Limit under
either of the following circumstances:

                  (i) if there is sufficient  availability under the Master Line
of Credit in the amount of the Foreign Exchange Reserve as of each Determination
Date,  provided  that the Bank in advance  shall  reserve the full amount of the
Foreign Exchange Reserve against the Master Line of Credit; or
                  (ii) if there is  insufficient  availability  under the Master
Line of Credit,  as to  settlements  within  any two (2)  Business  Day  period,
provided  that the Bank,  in its sole  discretion,  may:  (A) verify  good funds
overseas prior to crediting the Borrower's deposit account with the Bank (in the
case of the Borrower's  sale of foreign  currency);  or (B) debit the Borrower's
deposit account with the Bank prior to delivering  foreign currency overseas (in
the case of the Borrower's purchase of foreign currency).

         In the  case  of the  Borrower's  purchase  of  foreign  currency,  the
Borrower in advance shall instruct the Bank upon settlement  either to treat the
settlement amount as an advance under the Master Line of Credit, or to debit the
Borrower's account for the amount settled.

         The  Borrower  shall  execute  all  standard  from   applications   and
agreements of the Bank in connection  with the Exchange  Contracts and,  without
limiting any of the terms of such applications and agreements, the Borrower will
pay all standard  fees and charges of the Bank in  connection  with the Exchange
Contracts.

         Without  limiting any of the other terms of this  Agreement or any such
standard form  applications  and agreement of the Bank,  the Borrower  agrees to
indemnify  the Bank and hold it  harmless,  from and against any and all claims,
debts,   liabilities,   demands,   obligations,   actions,  costs  and  expenses
(including,  without  limitation,  attorneys'  fees  of  counsel  of the  Bank's
choice),  of every nature and description  which it may sustain or incur,  based
upon, arising out of, or in any way relating to any of the Exchange Contracts or
any transactions relating thereto or contemplated thereby.

         6. Letters of Credit.  Notwithstanding anything set forth in Article II
of the Loan  Agreement to the  contrary,  each Letter of Credit issued under the
Loan  Agreement  shall be issued under the Master Line of Credit.  No Letters of
Credit  shall be  required to be issued  after (or which  provide for a maturity
date after) the Master Line of Credit  Maturity Date. In the event that the Bank
issues any Letter(s) of Credit,  the maximum  amount of the credit  available in
connection with the Master Line of Credit shall be reduced by the face amount of
each Letter of Credit (so long as such Letter of Credit remains outstanding) and
any amounts drawn under any Letter of Credit shall be deemed  advanced under the
Master Line of Credit and shall bear interest and be payable in accordance  with
the terms of the  Master  Line of Credit  Note and shall be  secured to the same
extent and in the same manner as all other sums  advanced  under the Master Line
of Credit Note.  In addition,  the Borrower  agrees to pay the fees set forth in
paragraph  5(b) of Article II, of the Loan  Agreement  for each Letter of Credit
now or hereafter issued by the Bank.

         7.  Security.  As of the  effective  date  hereof,  the  provisions  of
paragraph 2 of Article  III, of the Loan  Agreement  are amended to provide that
the Loans shall be  unsecured,  unless and until the  Borrower's  ratio of Total
Liabilities  to Net Worth (as  calculated  in  accordance  with  paragraph  3 of
Article VII thereof) exceeds 2.0 to 1.0.

         8.  Financial  Covenants.  From and after the  effective  date  hereof,
paragraph 2 of Article VII of the Loan  Agreement is hereby amended and restated
in its entirety as follows:
                  2.  Tangible  Net  Worth.  The  Borrower  shall  at all  times
         maintain  Tangible Net Wroth of not less than Fifteen  Million  Dollars
         ($15,000,000).  For purposes of this Article VII,  "Tangible Net Worth"
         shall mean all capital  stock,  paid in capital and  retained  earnings
         less  all  treasury  stock,  amounts  due  from  officers,   directors,
         stockholders and members of their immediate families,  amounts due from
         affiliates,  investments  in  non-marketable  securities  or affiliated
         companies,  leasehold improvements,  goodwill,  non-compete agreements,
         capitalized  organization and development costs,  capitalized expenses,
         loan costs, patents, trademarks,  copyrights,  franchises, licenses and
         other intangible assets.

From and after the  effective  date hereof,  paragraphs 1 and 4 of Article VI of
the Loan  Agreement are deleted in their entirety.

         9. Year 2000.  The Borrower and each  Guarantor  hereby  represents and
warrants to the Bank that the Borrower and each Guarantor have:

                   (i) begun analyzing its operations and its  subsidiaries  and
affiliates  that could be  adversely  affected  by  failure to become  Year 2000
compliant (that is, that computer  applications,  imbedded  microchips and other
systems  will be able to  perform  date-sensitive  functions  prior to and after
December 31, 1999) and;
                  (ii)  developed a plan for becoming  Year 2000  compliant in a
timely  manner,  the  implementation  of which is on  schedule  in all  material
respects.  The  Borrower and each  Guarantor  reasonably  believes  that it will
become Year 2000 compliant for its operations and those of its  subsidiaries and
affiliates  on a timely basis except to the extent that a failure to do so could
not reasonably be expected to have a material  adverse effect upon the financial
condition  of  Borrower  or any  Guarantor.  The  Borrower  and  each  Guarantor
reasonably  believes  any  suppliers  and  vendors  that  are  material  to  the
operations  of  Borrower,  any  Guarantor  or  any  of  their  subsidiaries  and
affiliates  will be Year 2000  compliant  for their  own  computer  applications
except to the extent that a failure to do so could not reasonably be expected to
have a material  adverse effect upon the financial  condition of the Borrower or
any of the  Guarantors.  The  Borrower  will  promptly  notify Bank in the event
Borrower or any  Guarantor  determines  that any computer  application  which is
material  to  the  operations  of  Borrower  any  Guarantor,  or  any  of  their
subsidiaries  or any of their  material  vendors or suppliers  will not be fully
Year 2000  compliant on a timely  basis,  except to the extent that such failure
could not  reasonably  be  expected to have a material  adverse  effect upon the
financial condition of the Borrower or any of the Guarantors.

                                    RECITALS
                                    --------
         A. The  Lender  made a  secured  revolving  loan (the  "Master  Line of

Million Dollars  ($8,000,000),  which Master Line of Credit is evidenced by that

dated  September  26,  1994  from the  Borrower  to the  Lender  in the  maximum
principal amount of Eight Million Dollars ($8,000,000),  as amended and restated

                           MASTER LINE OF CREDIT NOTE
                           --------------------------
         $10,000,000                                            McLean, Virginia
                FOR VALUE RECEIVED, COMARCO, INC., a corporation organized under
         the laws of the State of  California (the "Borrower")promises to pay to
         the  order of  NATIONSBANK, N.A., a national banking  association,  its
         successors and assigns (the "Lender"), the principal sum of TEN MILLION
         DOLLARS ($10,000,000) (the "Principal  Sum"), or so much thereof as has
         been or may be advanced or readvanced  to or for  the  account  of  the
         Borrower,  together  with   interest  thereon  at  the  rate  or  rates
         hereinafter  provided,  in accordance with the following:

                  1.  Interest.  Except as otherwise  expressly set forth below,
         amounts outstanding  hereunder shall bear interest at the Prime Rate or
         the Floating  LIBOR Rate. For purposes  hereof,  the "Prime Rate" means
         the fluctuating prime rate of interest  established and declared by the
         Lender from time to time. The Prime Rate does not necessarily represent
         the lowest rate of interest charged by the Lender to its borrowers. For
         purposes  hereof,  the  "Floating  LIBOR Rate" shall mean a fluctuating
         rate of  interest  equal to the one  month  rate of  interest  (rounded
         upwards, if necessary to the nearest 1/100 of 1%) appearing on Telerate
         Page 3750 (or any  successor  page) as the one month  London  interbank
         offered  rate for  deposits  in  Dollars  at  approximately  11:00 a.m.
         (London  time) on the second  preceding  business day as adjusted  from
         time to time in Lender's sole  discretion for then  applicable  reserve
         requirements,  deposit insurance  assessment rates and other regulatory
         costs.  If for any reason such rate is not  available,  the term "LIBOR
         Rate"  shall mean the  fluctuating  rate of  interest  equal to the one
         month rate of interest  (rounded  upwards,  if necessary to the nearest
         1/100 of 1%)  appearing  on Reuters  Screen  LIBO Page as the one month
         London interbank  offered rate for deposits in Dollars at approximately
         11:00 a.m.  (London  time) on the second  preceding  business  day,  as
         adjusted  from  time to time  in  Lender's  sole  discretion  for  then
         applicable reserve requirements, deposit insurance assessment rates and
         other regulatory  costs;  provided,  however,  if more than one rate is
         specified on Reuters Screen LIBO page, the applicable rate shall be the
         arithmetic  mean of all such  rates.  "Telerate  Page  3750"  means the
         British Bankers  Association  Libor Rates  (determined as of 11:00 a.m.
         London time) that are published by Dow Jones Telerate, Inc.

                  So long as no event of default or any act,  event or condition
         which,  with notice or the passage of time or both, would constitute an
         event  of  default   under  any  Loan  Document  has  occurred  and  is
         continuing,  the Borrower  shall have the right to elect that specified
         amounts  advanced under this Note, bear interest for specified  periods
         (each being herein  referred to as a "LIBOR Rate Funding  Period"),  at
         the LIBOR Rate,  plus one and one half  percent  (1.50%)(the  "Adjusted
         LIBOR Rate"). Election by the Borrower of a LIBOR Rate interest rate as
         herein provided shall be made in a writing  delivered to the Lender not
         less than  three  (3)  Banking  Days  prior to the date of on which the
         LIBOR Rate is to begin,  and shall specify (1) the Banking Day on which
         the LIBOR  Rate is to be  effective  and the period for which the LIBOR
         Rate shall be  applicable  (which  shall be only 30, 60, 90 or 180 days
         and the expiration of which may not be later than the "Maturity Date");
         and (2) the principal  amount of this Note which shall bear interest at
         the Adjusted LIBOR Rate (each being herein referred to as a "LIBOR Rate
         Funding  Segment").  The  Borrower  may not  revoke  any such  election
         without  the  Lender's  written  consent.  Upon  the  expiration  of an
         applicable  LIBOR  Rate  Funding  Period,  unless  notice of LIBOR Rate
         election  from the  Borrower,  the rate of interest  applicable  to any
         LIBOR  Rate  Funding  Segment  (after  the  expiration  thereof)  shall
         automatically  convert at the end of the applicable  LIBOR Rate Funding
         Period, to the Prime Rate.

         For purposes hereof,  the "LIBOR Rate" shall mean the per annum rate of
         interest, as determined by the Lender in its sole discretion,  at which
         deposits in United States Dollars in an amount  approximately  equal to
         the  amount  for  which  the  rate is to be fixed  and with  maturities
         comparable to the interest period  selected by the Borrower,  to be the
         averages  of rates per annum for 11:00  a.m.  (London,  time),  two (2)
         Banking Days prior to the first day of such LIBOR Rate  Funding  Period
         for delivery on the first such day of such LIBOR Rate  Funding  Period,
         in amounts comparable to the applicable LIBOR Rate Funding Segment,  as
         adjusted for Federal  Reserve  Board reserve  requirements  and similar
         assessments, if any, imposed upon the Lender.

                  All  interest  payable  under the terms of this Note  shall be
         calculated on the basis of a 360-day year and the actual number of days
         elapsed.

                  2. Payments and Maturity.  The unpaid Principal Sum,  together
         with interest  thereon at the rate or rates  provided  above,  shall be
         payable as follows:

                           (a) Except as otherwise  provided in this Note,  this
         Note shall be payable in successive monthly installments of accrued and
         unpaid interest only, on the last day of each month commencing July 31,
         1998, and on the last day of each month thereafter to maturity;

                           (b) Unless  sooner paid,  the unpaid  Principal  Sum,
         together with all accrued and unpaid interest  thereon shall be due and
         payable in full on June 30, 2000.

                           The fact that the balance hereunder may be reduced to
         zero from time to time pursuant to the Loan  Agreement  will not affect
         the  continuing  validity of this Note or the Loan  Agreement,  and the
         balance may be increased to the Principal Sum after any such  reduction
         to zero.

                  3.  Default  Interest.  Upon  the  occurrence  of an  Event of
         Default (as hereinafter  defined),  the unpaid Principal Sum shall bear
         interest  thereafter  at a rate two percent (2%) per annum in excess of
         the then highest current rate or rates of interest hereunder until such
         Event of Default is cured.

                  4.  Late  Charges.  If the  Borrower  shall  fail to make  any
         payment  under the terms of this Note  within  five (5) days  after the
         date such  payment  is due,  the  Borrower  shall pay to the  Lender on
         demand a late charge equal to five percent (5%) of such payment.

                  5. Application and Place of Payments.  All payments  hereunder
         shall be applied  first to the payment of any late charges and costs of
         collections  then due  hereunder,  second to the payment of accrued and
         unpaid interest then due hereunder, and the remainder, if any, shall be
         applied to the unpaid  Principal  Sum.  Notwithstanding  the foregoing,
         accrued and unpaid interest on amounts  outstanding  hereunder  bearing
         interest on a LIBOR Rate basis shall be due and payable on the last day
         of the applicable  LIBOR Rate Funding Period (as herein defined) and if
         such LIBOR Rate Funding  Period is longer than ninety (90) days, on the
         ninetieth (90th) day of each LIBOR Rate Funding Period. All payments on
         account of this Note shall be paid in lawful money of the United States
         of  America  in  immediately  available  funds on or before  11:00 a.m.
         (Washington,  D.C. time) at its principal office in McLean, Virginia or
         at such  other  times and places as the Lender may at any time and from
         time to time designate in writing to the Borrower.

                  6.  Prepayment.  The  Borrower  may  prepay  amounts  accruing
         interest  based on the  Prime  Rate,  in whole or in part,  at any time
         without notice to the Lender without premium or penalty.  No prepayment
         of any other amounts  outstanding  hereunder shall be permitted without
         the prior written consent of the Lender.

                  7. Loan Agreement and Other Loan  Documents.  This Note is the
         "Master Line of Credit Note"  described in a Loan Agreement dated as of
         September  26,  1994 by and among the  Borrower  and  Comarco  Wireless

         delivered by the  Borrower,  the  Guarantors  and/or any other  person,
         singularly  or jointly  with any other  person,  evidencing,  securing,
         guaranteeing, or in connection with the Principal Sum, this Note and/or
         the Loan Agreement. All capitalized terms used herein and not otherwise
         defined  shall  have  the  meanings  given  to such  terms  in the Loan
         Agreement.

                  8. Events of Default. The occurrence of any one or more of the
         following events shall constitute an event of default (individually, an
         "Event of Default" and collectively, the "Events of Default") under the
         terms of this Note:

                           (a) The failure of the  Borrower to pay to the Lender
         within  five (5) days of when due any and all  amounts  payable  by the
         Borrower to the Lender under the terms of this Note; or

                           (b) The occurrence of an event of default (as defined
         therein)  under  the  terms and  conditions  of any of the  other  Loan
         Documents, including, but not limited to the Loan Agreement.

                  9. Remedies.  Upon the  occurrence of an Event of Default,  at
         the option of the Lender,  all amounts  payable by the  Borrower to the
         Lender  under the terms of this Note shall  immediately  become due and
         payable by the Borrower to the Lender  without  notice to the Borrower,
         or any other  person,  and the  Lender  shall  have all of the  rights,
         powers, and remedies available under the terms of this Note, any of the
         other  Loan  Documents  and all  applicable  laws.  The  Borrower,  the
         Guarantors and all endorsers, guarantors, and other parties who may now
         or in the future be primarily or secondarily  liable for the payment of
         the  indebtedness   evidenced  by  this  Note  hereby  severally  waive
         presentment,  protest and demand,  notice of protest,  notice of demand
         and of dishonor and  non-payment of this Note and expressly  agree that
         this Note or any payment  hereunder  may be extended  from time to time
         without in any way affecting  the  liability of the  Borrower,  and any
         guarantors and endorsers.

                  10.  Expenses.  The Borrower  promises to pay to the Lender on
         demand by the Lender all costs and  expenses  incurred by the Lender in
         connection with the collection and enforcement of this Note, including,
         without  limitation,  reasonable  attorneys'  fees and expenses and all
         court costs.

                  11.  Notices.  Any notice,  request,  or demand to or upon the
         Borrower or the Lender shall be deemed to have been  properly  given or
         made when delivered in accordance with the Loan Agreement.

                  12. Miscellaneous. Each right, power, and remedy of the Lender
         as provided for in this Note or any of the other Loan Documents, or now
         or hereafter  existing under any  applicable law or otherwise  shall be
         cumulative  and  concurrent  and shall be in  addition  to every  other
         right,  power,  or remedy provided for in this Note or any of the other
         Loan Documents or now or hereafter  existing under any applicable  law,
         and the  exercise or beginning of the exercise by the Lender of any one
         or more of such  rights,  powers,  or remedies  shall not  preclude the
         simultaneous  or later  exercise by the Lender of any or all such other
         rights,  powers,  or  remedies.  No  failure  or delay by the Lender to
         insist upon the strict performance of any term, condition, covenant, or
         agreement  of  this  Note or any of the  other  Loan  Documents,  or to
         exercise any right,  power, or remedy consequent upon a breach thereof,
         shall  constitute a waiver of any such term,  condition,  covenant,  or
         agreement or of any such breach, or preclude the Lender from exercising
         any such right, power, or remedy at a later time or times. By accepting
         payment  after the due date of any  amount  payable  under the terms of
         this Note,  the Lender shall not be deemed to waive the right either to
         require prompt payment when due of all other amounts  payable under the
         terms of this Note or to declare an Event of Default for the failure to
         effect  such  prompt  payment  of any such other  amount.  No course of
         dealing or conduct shall be effective to amend, modify, waive, release,
         or change any provisions of this Note.

                  13.  Partial  Invalidity.  In the event any  provision of this
         Note (or any  part of any  provision)  is held by a court of  competent
         jurisdiction to be invalid,  illegal,  or unenforceable in any respect,
         such invalidity,  illegality,  or unenforceability shall not affect any
         other  provision (or remaining part of the affected  provision) of this
         Note; but this Note shall be construed as if such invalid,  illegal, or
         unenforceable  provision  (or part  thereof) had not been  contained in
         this  Note,  but  only  to  the  extent  it  is  invalid,  illegal,  or
         unenforceable.

                  14.   Captions.   The  captions   herein  set  forth  are  for
         convenience only and shall not be deemed to define,  limit, or describe
         the scope or intent of this Note.

                  15. Applicable Law. The Borrower  acknowledges and agrees that
         this  Note  shall  be  governed  by the  laws  of the  Commonwealth  of
         Virginia,  even  though for the  convenience  and at the request of the
         Borrower, this Note may be executed elsewhere.

                  16. Arbitration. Any controversy or claim between or among the
         parties  hereto  including  but not limited to those  arising out of or
         relating  to  this  Agreement  or any of the  other  Loan  Documents  ,
         including any claim based on or arising from any alleged tort, shall be
         determined  by  binding  arbitration  in  accordance  with the  Federal
         Arbitration Act (or if not applicable,  the applicable  state law), the
         rules of practice  and  procedure  for the  arbitration  of  commercial
         disputes  of  Judicial   Arbitration  and  Mediation   Services,   Inc.
         (J.A.M.S.) and the "special rules" set forth below. In the event of any
         inconsistency,  the special  rules  shall  control.  Judgment  upon any
         arbitration award may be entered in any court having jurisdiction.  Any
         party to this  agreement  may bring an action,  including  a summary or
         expedited proceeding, to compel arbitration of any controversy or claim
         to which this Agreement  applies in any court having  jurisdiction over
         such action.

                           (a) Special Rules. The arbitration shall be conducted
         in the  city of the  Borrower's  domicile  at time of this  Agreement's
         execution and administered by J.A.M.S.  who will appoint an arbitrator;
         if  J.A.M.S.  is unable or legally  precluded  from  administering  the
         arbitration,  then the American Arbitration Association will serve. All
         arbitration hearings will be commenced within 90 days of the demand for
         arbitration;  further,  the  arbitrator  shall only,  upon a showing of
         cause,  be permitted to extend the  commencement of such hearing for up
         to an additional 60 days.

                           (b) Reservation of Rights.  Nothing in this Agreement
         shall  be  deemed  to (i)  limit  the  applicability  of any  otherwise
         applicable  statutes of limitation or repose and any waivers  contained
         in this  Note  or (ii) be a  waiver  by the  Lender  of the  protection
         afforded to it by 12 U.S.C. Section 91 or any substantially  equivalent
         state law; or (iii) limit the right of the Lender (a) to exercise  self
         help remedies such as (but not limited to) setoff,  or (b) to foreclose
         against any real or personal property collateral, or (c) to obtain from
         a court provisional or ancillary  remedies such as (but not limited to)
         injunctive relief, writ of possession or the appointment of a receiver.
         Lender  may  exercise  such self  help  rights,  foreclosure  upon such
         property,  or obtain such  provisional  or ancillary  remedies  before,
         during or after the  pendency  of any  arbitration  proceeding  brought
         pursuant to this Agreement.  Neither the exercise of self help remedies
         nor the  institution  or  maintenance  of an action for  foreclosure or
         provisional  or  ancillary  remedies  shall  constitute a waiver of the
         right of any party,  including  the  claimant  in any such  action,  to
         arbitrate the merits of the controversy or claim occasioning  resort to
         such remedies.


         3.  Governing  Law,  Etc.  This  Agreement  shall  be  governed  by and
construed in accordance with the laws of the  Commonwealth of Virginia and shall
be deemed to be an instrument under seal pursuant to said law. The headings used
in this  Agreement are for the  convenience of the parties and shall not be used
to interpret or construe the provisions hereof.
         4. Not A  Novation.  It is  expressly  understood  and agreed  that the
indebtedness  evidenced by the Third Replacement  Master Line of Credit Note has
not been  extinguished or discharged  hereby.  The Borrower and the Lender agree
that the  execution  of this  Agreement  is not  intended and shall not cause or
result in a novation with regard to the Third Replacement  Master Line of Credit
Note.

officer as of the day and year first above written.
