                        NATIONAL INSTRUMENTS CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - Basis of Presentation

The accompanying  unaudited  financial  statements should be read in conjunction
with the consolidated  financial statements and notes thereto for the year ended
December 31, 1996,  included in the Company's  annual report on Form 10-K, filed
with the Securities and Exchange Commission.  In the opinion of management,  the
accompanying   consolidated   financial   statements   reflect  all  adjustments
(consisting  only of normal  recurring  items)  considered  necessary to present
fairly the  financial  position  of  National  Instruments  Corporation  and its
consolidated subsidiaries at June 30, 1997 and December 31, 1996, the results of
operations  for the  three-month  and six-month  periods ended June 30, 1997 and
1996, and the cash flows for the six-month periods ended June 30, 1997 and 1996.
Operating  results for the three-month and six-month periods ended June 30, 1997
are not necessarily  indicative of the results that may be expected for the year
ending December 31, 1997.

NOTE 2 - Earnings Per Share

Earnings per share are  computed by dividing net income by the weighted  average
number of common shares and common share  equivalents  outstanding (if dilutive)
during each period.  Common share equivalents include stock options.  The number
of common share  equivalents  outstanding  relating to stock options is computed
using the treasury stock method.

In February 1997, the Financial  Accounting  Standards Board issued Statement of
Financial  Accounting Standards No. 128, "Earnings per Share." The new standard,
which is effective  for  financial  statements  issued for periods  ending after
December 15, 1997,  establishes  standards for computing and presenting earnings
per share (EPS) and upon adoption  requires  restatement of all prior-period EPS
data  presented.  The Company will implement this standard in the fourth quarter
of 1997. The implementation of the standard will result in the presentation of a
basic EPS  calculation  in the  consolidated  financial  statements as well as a
diluted EPS  calculation.  If the Company had adopted the new  standard  for the
second  quarter of 1997,  basic EPS would have been $0.40 per share and  diluted
EPS would  have  approximated  the EPS of $0.38  presented  in the  accompanying
consolidated statement of income.

NOTE 3 - Inventories

Inventories consist of the following (in thousands):

         NET SALES.  Consolidated net sales increased by $9.9 million or 20% for
the three months ended June 30, 1997 to $60.1 million from $50.2 million for the
three  months ended June 30, 1996,  and  increased  $18 million or 19% to $114.7
million  for the six months  ended  June 30,  1997 from  $96.6  million  for the
comparable 1996 period.  The increase in sales is primarily  attributable to the
introduction of new and upgraded  products,  increased market  acceptance of the
Company's products,  and an expanding customer base. North American sales in the
second quarter of 1997  increased 26% over the second quarter of 1996,  compared
with an increase of 23% in the second quarter of 1996 from the second quarter of
1995.  North American sales for the six months ended June 30, 1997 increased 22%
from the six months  ended June 30,  1996,  compared  with an increase of 23% in
1996 compared to the same period in 1995.

         International  sales as a  percentage  of  consolidated  sales  for the
quarter  and six months  ended June 30, 1997  decreased  from 42.8% to 39.6% and
from 43.1% to 41.5%, respectively, over the comparable 1996 periods. Compared to
1996, the Company's European net sales increased by 14% to $16.5 million for the
quarter ended June 30, 1997 and by 14% to $31.5 million for the six months ended
June 30, 1997. Net sales in Asia Pacific  increased by 5% to $7.3 million in the
quarter ended June 30, 1997 compared to 1996 and by 14% to $16.0 million for the
six months ended June 30, 1997.  The decline in the sales growth  percentages in
the Asia Pacific region is directly  attributable to lower sales growth rates in
Japan.  The  Company  believes  that  sales  growth  rates  in Japan  have  been
negatively  impacted by the increase in the consumption tax rate in Japan,  from
3% to 5% effective  April 1, 1997,  which has affected the timing of  customers'
purchasing decisions.  In addition,  the Company faces a continuing challenge in
finding qualified bilingual sales and marketing personnel to staff operations in
Japan.  The  Company  expects  sales  outside of North  America to  continue  to
represent a significant portion of its revenue.

     International sales are subject to inherent risks,  including  fluctuations
in local economies,  difficulties in staffing and managing  foreign  operations,
greater  difficulty  in  accounts  receivable  collection,  costs  and  risks of
localizing  products for foreign  countries,  unexpected  changes in  regulatory
requirements, tariffs and other trade barriers, difficulties in the repatriation
of earnings  and the burdens of complying  with a wide variety of foreign  laws.
Sales made by the Company's  direct sales offices in Europe and Asia Pacific are
denominated in local  currencies,  and accordingly,  the US dollar equivalent of
these sales is  affected  by changes in the value of the US dollar.  Between the
second quarter of 1997 and the second quarter of 1996 the weighted average value
of the US dollar  increased by 8.8%,  causing an  equivalent  decrease in the US
dollar value of the Company's foreign currency sales and expenses. This weighted
average is  calculated  as the  percentage  change in the value of the  currency
relative to the US dollar,  multiplied by the proportion of international  sales
recorded in the  particular  currency.  If the weighted  average value of the US
dollar in the  second  quarter  of 1997 had been the same as that in the  second
quarter of 1996,  the Company's  sales for the second quarter of 1997 would have
been  $62.2  million  This  effect  is 3.5% of  consolidated  net  sales  in the
aggregate.  European  sales for the  second  quarter of 1997 would have been $18
million,  representing  an increase of $3.4 million and would have  reflected an
increase in the second  quarter 1997 sales over the second quarter 1996 sales by
24% instead of 14%. Asia Pacific sales for the second quarter of 1997 would have
been $7.8 million, representing an increase of $977,000 and would have reflected
an increase in second  quarter 1997 sales over second  quarter 1996 sales by 14%
instead  of 5%. If the  weighted  average  value of the dollar in the six months
ended June 30,  1997 had been the same as that in the six months  ended June 30,
1996, the Company's  year-to-date sales would have been $119 million. Since most
of the  Company's  international  operating  expenses are also incurred in local
currencies the change in exchange rates has the corresponding effect of reducing
operating expenses by $800,000.  If the current trend in the value of the dollar
continues  throughout  1997, it will continue to have the effect of lowering the
US dollar equivalent of international sales and operating expenses.

10
     GROSS PROFIT. As a percentage of net sales, gross profit increased to 76.7%
for the second  quarter  of 1997 from  74.6% for the second  quarter of 1996 and
increased  to  77.0%  for the  first  six  months  of 1997  from  75.1%  for the
comparable  period a year ago. The higher margin for the second  quarter of 1997
compared to the second quarter of 1996 is  attributable to  manufacturing  labor
and overhead spending efficiencies and lower material costs.

     The  marketplace  for the  Company's  products  dictates  that  many of the
Company's  products be shipped quickly after an order is received.  As a result,
the  Company  is  required  to  maintain  significant  inventories.   Therefore,
inventory  obsolescence  is a risk for the Company  due to frequent  engineering
changes,  shifting customer demand,  the emergence of new industry standards and
rapid  technological  advances including the introduction by the Company, or its
competitors,  of products embodying new technology.  While the Company maintains
valuation  allowances for excess and obsolete inventory and management continues
to monitor the adequacy of such valuation allowances,  there can be no assurance
that such valuation allowances will be sufficient.

     SALES AND MARKETING. Sales and marketing expenses for the second quarter of
1997  increased  to $21.5  million,  a 19%  increase,  as compared to the second
quarter of 1996,  and increased 16% to $41.4 million for the first six months of
1997 from the comparable  1996 period.  As a percentage of net sales,  sales and
marketing  expenses decreased to 35.8% for the second quarter of 1997 from 36.0%
for the second  quarter of 1996 and  decreased to 36.1% for the first six months
of 1997  from  36.9% for the first six  months of 1996.  The  increase  in these
expenses in absolute  dollar amounts is primarily  attributable  to increases in
sales and  marketing  personnel and  increased  sales and marketing  activities.
Overall sales and marketing personnel increased from 515 at June 30, 1996 to 614
at June 30, 1997.  The Company  expects sales and  marketing  expenses in future
periods to increase in absolute  dollars,  and to fluctuate  as a percentage  of
sales based on initial marketing and advertising  campaign costs associated with
major new product  releases,  the opening of new sales offices and the timing of
domestic and international conferences and trade shows.

     RESEARCH AND DEVELOPMENT.  Research and development  expenses  increased to
$7.7 million for the quarter ended June 30, 1997, a 12% increase, as compared to
$6.9  million for the three months ended June 30,  1996,  and  increased  20% to
$14.1  million for the six months ended June 30, 1997 from the  comparable  1996
period.  As a  percentage  of  net  sales,  research  and  development  expenses
represented  12.7% and 13.6% for the second  quarters  ended  June 30,  1997 and
1996,  respectively,  and 12.3% and 12.2% for the six months ended June 30, 1997
and 1996,  respectively.  The above comparisons include research and development
expenses  of $1.0  million in the second  quarter of 1996 for the  write-off  of
in-process  research  and  development  technology  related to the  purchase  of
Georgetown Systems,  Inc. ("GSI").  Excluding the effects of the GSI charge, the
increase in research and development expenses in the three months ended June 30,
1997 compared to the three months ended June 30, 1996 is mainly due to increases
in  personnel  costs  from  increased  hiring,  outside  tooling  and  prototype
materials.  The Company  believes  that a  significant,  on-going  investment in
research  and  development  is  required to remain  competitive.  As a result of
increased  recruiting efforts, the Company expects its intern personnel expenses
to increase in the third quarter of 1997.

11
     The Company capitalizes  software  development costs in accordance with the
Statement of Financial  Accounting  Standards No. 86. The Company amortizes such
costs over the related product's estimated economic useful life, generally three
years  beginning  when  a  product  becomes   available  for  general   release.
Amortization  expense  totaled  $361,000 and $428,000 for the quarter ended June
30, 1997 and 1996, respectively, and $737,000 and $713,000 during the six months
ended  June  30,  1997  and  1996,  respectively.   Software  development  costs
capitalized  were $88,000 and $1.2  million for the quarter  ended June 30, 1997
and 1996,  respectively,  and $406,000 and $1.9 million for the first six months
of 1997 and 1996,  respectively.  The amounts  capitalized in the second quarter
and first six months of 1996 include $1.0 million of software  development costs
related to the GSI acquisition.

     GENERAL AND  ADMINISTRATIVE.  General and  administrative  expenses for the
second  quarter  ended June 30,  1997  increased  4% to $4.5  million  from $4.4
million for the comparable prior year period.  For the first six months of 1997,
general and  administrative  expenses  increased  3% to $8.8  million  from $8.6
million for the first six months of 1996. As a percentage of net sales,  general
and  administrative  expenses  decreased to 7.6% for the quarter  ended June 30,
1997 from 8.7% for the second  quarter  of 1996.  During the first six months of
1997, general and administrative  expenses decreased as a percentage of sales to
7.7% from 8.8% for the comparable prior year period. The decrease in general and
administrative expenses as a percent of sales is due to operational efficiencies
achieved as a result of increased systems integration during the past two years.
The Company's general and  administrative  expense increased in absolute dollars
mainly due to  additional  personnel.  The  Company  expects  that  general  and
administrative  expense in future periods will increase in absolute  amounts and
will fluctuate as a percentage of net sales.

     INTEREST INCOME,  NET.  Interest income,  net in the second quarter of 1997
increased to $705,000 from $314,000 in the second  quarter of 1996 and increased
to $1.4 million for the first six months of 1997 from $571,000 for the first six
months of 1996.  This  increase is primarily due to an increase in the Company's
cash and  investment  balances.  Interest  expense in the second quarter of 1997
decreased to $125,000 from $242,000 in the second  quarter of 1996 and decreased
to  $258,000  for the first six months of 1997 from  $472,000  for the first six
months of 1996.  This  decrease is  attributed  to repayments of debt in January
1997.

     FOREIGN EXCHANGE LOSS, NET. Net foreign  exchange losses  recognized in the
second  quarter of 1997 were  $306,000  compared to $287,000  recognized  in the
second  quarter of 1996.  Net foreign  exchange  losses of ($1.3)  million  were
recognized  for the first six months of 1997  compared to $665,000 for the first
six months of 1996. These results are  attributable to movements  between the US
dollar  and the local  currencies  in  countries  in which the  Company's  sales
subsidiaries  are  located.  The Company  recognizes  the local  currency as the
functional  currency of its  international  subsidiaries.  The net losses in the
first  six  months of 1997 are a result  of the  strengthening  of the US dollar
against local currencies,  primarily the Japanese yen and the French franc which
weakened in the first half of 1997.



12


     The Company enters into foreign currency forward exchange contracts against
a majority of its intercompany foreign currency-denominated receivables in order
to reduce its  exposure  to  significant  foreign  currency  fluctuations.  This
hedging  strategy  only  partially  addresses  the  Company's  risks in  foreign
currency  transactions  as the  Company  does not  currently  hedge  anticipated
transactions.  There can be no assurance  that this strategy will be successful.
The Company's  hedging strategy has reduced the foreign exchange losses recorded
by  $770,000   during  the  six-month   period  ended  June  30,  1997.  If  the
strengthening of the US dollar that occurred  throughout 1996 and the first half
of 1997  is  experienced  during  the  remainder  of  1997,  the  Company  could
experience significant foreign exchange losses due to the foreign exchange risks
that are not addressed by the Company's hedging strategy.  The Company typically
limits the  duration  of its foreign  exchange  contract to 90 days and does not
invest in contracts for speculative purposes.

     PROVISION  FOR INCOME TAXES.  The  provision  for income taxes  reflects an
effective  tax rate of 33% and 34% for both the three  months and the six months
ended June 30, 1997 and 1996,  respectively.  The decrease in the effective rate
resulted  from a change  in the mix of income  among  taxing  jurisdictions  and
utilization of tax credits for taxes paid in higher tax rate  jurisdictions.  As
of June 30, 1997, six of the Company's  subsidiaries  had available,  for income
tax purposes,  foreign net operating loss  carryforwards of approximately  $1.01
million of which $654,000  expire between 2000 and 2007. The remaining  $406,000
of loss  carryforwards  may be carried  forward  indefinitely  to offset  future
taxable income in the related tax jurisdictions.


Liquidity and Capital Resources

     The Company is currently  financing its  operations  and capital  resources
through cash flow from operations.  Historically,  the Company also financed its
capital  expenditures,  such as the new  manufacturing  facility  constructed in
1995,  through  borrowings  from financial  institutions.  At June 30, 1997, the
Company  had  working  capital of  approximately  $111  million  compared to $99
million at December 31, 1996. The increase in working capital is attributable to
an increase in cash and short term  investments  of $5.0 million and an increase
of net accounts  receivable  of $4.0 million from  December 31, 1996 to June 30,
1997.

     Accounts  receivable  increased  to $37  million at June 30,  1997 from $33
million at Dec. 31, 1996,  as a result of higher sales levels.  Receivable  days
outstanding  decreased  to 56 at June 30, 1997  compared  to 57 at December  31,
1996.  Inventory levels increased with  consolidated  inventory  balances of $14
million and $12 million at June 30, 1997 and December  31,  1996,  respectively.
Inventory  increases were the result of planned efforts to increase inventory in
order to support the forecasted  sales levels.  Inventory turns of 4.1 represent
an improvement over turns of 3.7 at December 31, 1996.

     Cash used in the first six months of 1997 for the  purchase of the property
and  equipment  totaled  $5.4  million  and for the  capitalization  of software
development  costs totaled  $406,000.  The Company has begun  construction of an
office building to be located next to its manufacturing facility which opened in
July  1995.  It is  currently  anticipated  that a  significant  portion  of the
construction  costs will be paid out of the Company's  existing  working capital
and  future  cash  flows.  The  Company  estimates  the  total  cost for the new
building,  including  furniture,  fixtures  and  equipment,  will range from $30
million to $35 million with  approximately  $21 million  expected to be incurred
during 1997 and the  remainder  in the first half of 1998.  In May of 1997,  the
Company entered into firm commitments of approximately $23.5 million for the new
building.  The actual  level of spending  may exceed this amount  depending on a
variety of factors, including unforeseen difficulties in construction.

13
     The Company currently expects to fund expenditures for capital requirements
as well as  liquidity  needs  created  by  changes  in  working  capital  from a
combination  of available cash and short-term  investment  balances,  internally
generated  funds,  and  financing   arrangements   with  its  current  financial
institutions.  The Company has a $24.0 million credit agreement with NationsBank
of Texas,  N.A. which consists of (i) an $8.0 million  revolving line of credit,
and (ii) a $7.5  million  equipment  line of credit,  and (iii) an $8.5  million
manufacturing facility loan. As of June 30, 1997, the Company had no outstanding
balances under any of the lines of credit and had repaid all of the loans except
the $8.5  million  manufacturing  facility  loan,  which had a  balance  of $6.4
million.  The revolving  line of credit  expires on June 30, 1998. The Company's
credit  agreements  contain certain  financial  covenants and restrictions as to
various matters,  including the bank's prior approval of significant mergers and
acquisitions.  Borrowings  under  the  line  of  credit  are  collateralized  by
substantially all of the Company's assets.

     The Company believes that its cash flow from operations,  if any,  existing
cash  balances  and  short-term  investments  and  available  credit  under  the
Company's  existing  credit  facilities,  will be  sufficient  to meet  its cash
requirements for at least the next twelve months.

Issues and Outlook

     FLUCTUATIONS  IN  QUARTERLY  RESULTS.  The  Company's  quarterly  operating
results  have  fluctuated  in the past and may  fluctuate  significantly  in the
future due to a number of  factors,  including:  changes in the mix of  products
sold; the availability and pricing of components from third parties  (especially
sole sources);  the timing of orders;  level of pricing of international  sales;
fluctuations in foreign  currency  exchange rates; the difficulty in maintaining
margins,  including the higher margins  traditionally  achieved in international
sales;  and  changes in pricing  policies by the  Company,  its  competitors  or
suppliers.  As has  occurred  in the past and as may be expected to occur in the
future,  new software  products of the Company or new operating systems of third
parties on which the Company's  products are based, often contain bugs or errors
that can result in reduced  sales and/or cause the  Company's  support  costs to
increase,  having a material adverse impact on the Company's  operating results.
Furthermore,  the Company serves a number of industries such as  semiconductors,
telecommunications,  aerospace,  defense and  automotive  which are  cyclical in
nature.  Downturns in these  industries  could have a material adverse effect on
the Company's operating results.

     In  recent  years,  the  Company's  revenues  have  been  characterized  by
seasonality,  with revenues  typically being  relatively  constant in the first,
second and third quarters, and growing in the fourth quarter. If this historical
pattern continues,  revenues for the third quarter of 1997 may be below revenues
for the second  quarter of 1997.  The Company  believes the  seasonality  of its
revenue results from the international mix of its revenue and the variability of
the  budgeting  and  purchasing   cycles  of  its  customers   throughout   each
international  region.  In addition,  total operating  expenses have in the past
tended to be higher  in the  second  and third  quarters  of each  year,  due to
increased sales and marketing activities.  If this historical pattern continues,
net income for the third quarter of 1997 will be less than that in the first and
second  quarter of 1997.  The Company's  results of operations  may be adversely
affected by lower sales levels in Europe which typically occur during the summer
months.

14
     MANAGEMENT  INFORMATION  SYSTEMS.  The Company does not  currently  have an
integrated world-wide management information system. While the Company is in the
process  of  implementing  a new  world-wide  system,  the  deficiencies  in its
existing information  resources have at times inhibited  management's ability to
manage  certain  aspects of the  Company's  operations in a timely  manner.  The
Company has implemented all of the US components of the new system.  The Company
plans to  complete  transition  of the sales  and  receivable  functions  of the
European  operations by the third quarter of 1997. The Company  implemented  the
new system for its Japanese  operation in May of 1997. The rest of the Company's
Asia  Pacific  operations  continue  using  independent  management  information
systems.  The Company is working to eventually  achieve a world-wide  management
information  system that will allow for the  consolidation of common  functions,
reduced costs, and improvements in the ability to deliver product world-wide. No
assurance  can be given  that the  Company's  efforts  will be  successful.  The
failure to receive  adequate,  accurate and timely financial  information  could
inhibit management's ability to make effective and timely decisions.

     NEW  PRODUCT  INTRODUCTIONS  AND  MARKET  ACCEPTANCE.  The  market  for the
Company's  products is characterized  by rapid  technological  change,  evolving
industry  standards,   changes  in  customer  needs  and  frequent  new  product
introductions, and is therefore highly dependent upon timely product innovation.
The  Company's  success is  dependent  in part on its  ability  to  successfully
develop and  introduce  new and  enhanced  products on a timely basis to replace
declining  revenues  from  older  products,  and on  increasing  penetration  in
international  markets.  In the past,  the Company has  experienced  significant
delays between the announcement and the commercial availability of new products.
Any  significant  delay in releasing new products could have a material  adverse
effect on the ultimate success of a product and other related products and could
impede  continued  sales of  predecessor  products,  any of which  could  have a
material  adverse  effect on the Company's  operating  results.  There can be no
assurance  that the Company will be able to  introduce  new products on a timely
basis,  that  new  products  will  achieve  market  acceptance  or that any such
acceptance will be sustained for any significant period.  Moreover, there can be
no  assurance  that the  Company's  efforts  to  increase  international  market
penetration will be successful.

     OPERATION  IN  INTENSELY  COMPETITIVE  MARKETS.  The  markets  in which the
Company  operates  are  characterized  by  intense   competition  from  numerous
competitors, and the Company expects to face further competition from new market
entrants in the future.  A key  competitor is  Hewlett-Packard  Company  ("HP"),
which has been the leading supplier of traditional instrumentation solutions for
decades.  Although HP offers its own line of proprietary instrument controllers,
HP also offers hardware and software  add-on  products for  third-party  desktop
computers and workstations that provide solutions that directly compete with the
Company's virtual instrumentation  products. HP is aggressively  advertising and
marketing products that are competitive with the Company's products.  Because of
HP's  dominance  in the  instrumentation  business,  changes  in  its  marketing
strategy  or  product  offerings  could have a  material  adverse  effect on the
Company operating results.

15
     The  Company  believes  its  ability to compete  successfully  depends on a
number of factors  both within and outside its control,  including:  new product
introductions by competitors;  product pricing; quality and performance; success
in  developing  new  products;  adequate  manufacturing  capacity  and supply of
components and materials; efficiency of manufacturing operations;  effectiveness
of sales and marketing  resources and strategies;  strategic  relationships with
other suppliers;  timing of new product introductions by the Company; protection
of the  Company's  products by  effective  use of  intellectual  property  laws;
general market and economic  conditions;  and government  actions throughout the
world.  There can be no  assurance  that the  Company  will be able to  complete
successfully in the future.

     DEPENDENCE  ON KEY  SUPPLIERS.  The Company's  manufacturing  processes use
large volumes of high-quality  components and subassemblies  supplied by outside
sources.  Several of these  components  are  available  through  sole or limited
sources.   Sole-source  components  purchased  by  the  Company  include  custom
application-specific  integrated  circuits  ("ASICs") and other components.  The
Company has in the past  experienced  delays and quality  problems in connection
with sole-source  components,  and there can be no assurance that these problems
will not recur in the future.

     PROPRIETARY  RIGHTS AND  INTELLECTUAL  PROPERTY  LITIGATION.  The Company's
success depends in part on its ability to obtain and maintain  patents and other
proprietary rights relative to the technologies used in its principal  products.
Despite the Company's  efforts to protect its proprietary  rights,  unauthorized
parties  may have in the past  infringed  or violated  certain of the  Company's
intellectual  property rights.  As is typical in the industry,  the Company from
time  to  time  may  be  notified  that  it  is  infringing  certain  patent  or
intellectual  property rights of others.  While no actions are currently pending
by or against the Company, there can be no assurance that litigation will not be
initiated  in  the  future  which  may  cause  significant  litigation  expense,
liability and a diversion of  management's  attention  which may have a material
adverse affect on results of operations.

    DEPENDENCE ON KEY MANAGEMENT AND TECHNICAL PERSONNEL.  The Company's success
depends to a  significant  degree upon the  continued  contributions  of its key
management,  marketing,  research and development and operational personnel. The
Company  has no  agreements  providing  for  the  employment  of any of its  key
employees for any fixed term and the  Company's  key  employees may  voluntarily
terminate  their  employment  with  the  Company  at any  time.  The loss of the
services of one or more of the  Company's key employees in the future could have
a material  adverse affect on operating  results.  The Company also believes its
future  success will depend in large part upon its ability to attract and retain
additional  highly  skilled  management,   technical,  marketing,  research  and
development,  product  development and operational  personnel with experience in
managing large and rapidly  changing  companies as well as training,  motivating
and  supervising  the  employees.  Competition  for key personnel is intense and
there can be no assurance  that the Company will be  successful in retaining its
existing key personnel or attracting and retaining additional key personnel.
