                             HEARTLAND EXPRESS, INC.
                                AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

Note 1.  Basis of Presentation

     The accompanying  unaudited  consolidated financial statements of Heartland
Express,  Inc. and subsidiaries (the "Company") have been prepared in accordance
with generally accepted accounting  principles for interim financial information
and with the instructions to Form 10-Q and Regulation S-X. Accordingly,  they do
not include all of the information and footnotes  required by generally accepted
accounting  principles  for  complete  financial  statements.  In the opinion of
management,  all normal,  recurring adjustments  considered necessary for a fair
presentation  have been  included.  The financial  statements  should be read in
conjunction  with the audited  consolidated  financial  statements  for the year
ended  December  31,  2005  included  in the  Annual  Report on Form 10-K of the
Company filed with the Securities and Exchange  Commission.  Interim  results of
operations are not necessarily  indicative of the results to be expected for the
full year or any other interim  periods.  There were no changes to the Company's
significant accounting policies during the quarter.

Note 2.  Use of Estimates

     The preparation of financial  statements in conformity with U. S. generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

Note 3.  Segment Information

     The Company has ten operating divisions; however, it has determined that it
has one  reportable  segment.  All of the divisions are managed based on similar
economic  characteristics.  Each of the regional  operating  divisions  provides
short to  medium-haul  truckload  carrier  services of general  commodities to a
similar  class  of  customers.  In  addition,  each  division  exhibits  similar
financial  performance,  including average revenue per mile and operating ratio.
As a result of the foregoing,  the Company has determined that it is appropriate
to aggregate its operating divisions into one reportable segment consistent with
the  guidance  in SFAS No.  131.  Accordingly,  the  Company  has not  presented
separate  financial  information  for  each of its  operating  divisions  as the
Company's consolidated financial statements present its one reportable segment.

Note 4.  Cash and Cash Equivalents

     Cash   equivalents  are   short-term,   highly  liquid   investments   with
insignificant  interest  rate risk and  original  maturities  of three months or
less.  Restricted and designated cash and short-term  investments  totaling $4.6
million at March 31, 2006 and $4.7  million at December 31, 2005 are included in
other assets.  The restricted funds represent those required for  self-insurance
purpose and designated  funds that are earmarked for a specific  purpose not for
general business use.

Note 5.  Short-term Investments

     The Company  investments  are  primarily in the form of tax free  municipal
bonds  with  interest  reset  provisions  or  short-term  municipal  bonds.  The
investments  typically have a put option of 28 or 35 days. At the reset date the
Company has the option to roll the investment over or sell. The Company receives
the par value of the investment on the reset date if sold. The cost approximates
fair value due to the nature of the  investment.  Therefore,  accumulated  other



                                       6


comprehensive  income (loss) has not been recognized as a separate  component of
stockholders'  equity.  Investment  income  received  is  generally  exempt from
federal income taxes.

Note 6.  Property, Equipment, and Depreciation

     Property and equipment are stated at cost,  while  maintenance  and repairs
are charged to operations as incurred.

     Effective July 1, 2005 gains from the trade of revenue  equipment are being
recognized  in  operating  income in  compliance  with  Statement  of  Financial
Accounting Standards No. 153, "Accounting for Non-monetary Transactions".  Prior
to July 1, 2005 gains from the trade-in of revenue  equipment  were deferred and
presented  as a reduction  of the  depreciable  basis of new revenue  equipment.
Operating  results for the quarter were favorably  impacted by $2.7 million from
gains on the trade-in of revenue  equipment,  net of the associated  increase in
depreciation  expense  as a result  of the  higher  depreciable  basis of traded
revenue equipment acquired since July 1, 2005.

Note 7.  Earnings Per Share:

     Earnings  per share are  based  upon the  weighted  average  common  shares
outstanding during each year. Heartland Express has no common stock equivalents;
therefore, diluted earnings per share are equal to basic earnings per share.

Note 8.  Share Based Compensation

     On March 7, 2002,  the  Company  president  transferred  136,125 of his own
shares  establishing  a restricted  stock plan on behalf of key  employees.  The
shares  vest  over a five  year  period  or  upon  death  or  disability  of the
recipient.  The  shares  were  valued  at the  March  7,  2002  market  value of
approximately $2.0 million.  The market value of $2.0 million is being amortized
over a five year period as compensation expense. Compensation expense of $94,228
and  $95,107  for the three  month  periods  ended  March  31,  2006 and 2005 is
recorded in  salaries,  wages,  and  benefits on the  consolidated  statement of
income.  As of March 31, 2006, there was $344,473 of unearned  compensation cost
related to the restricted  stock granted.  This cost will be recognized over the
next two years.  All unvested  shares are included in the Company's 73.8 million
outstanding shares.

     A summary  of the  Company's  non-vested  restricted  stock as of March 31,
2006,  and changes  during the three months ended March 31, 2006 is presented in
the table below:

                                                                    Grant-date
                                                          Shares    Fair Value
                                                         --------   ----------
Non-vested stock outstanding at January 1, 2006           51,150     $ 14.66
Granted                                                        -           -
Vested                                                   (24,675)      14.66
Forfeited                                                      -           -
                                                         -------    --------
Non-vested stock outstanding at March 31, 2006            26,475     $ 14.66
                                                         =======    ========

The fair value of the shares  vested  awards was  $560,289  and $530,075 for the
three months ended March 31, 2006 and 2005, respectively.

     In December 2004, the FASB issued SFAS No. 123(R), "Share-Based Payment," a
revision of SFAS No. 123, which addresses the accounting for share-based payment
transactions.  SFAS No.  123(R)  eliminates  the ability to account for employee
share-based compensation  transactions using APB Opinion No. 25, "Accounting for
Stock  Issued  to  Employees,"   and  generally   requires   instead  that  such
transactions be accounted and recognized in the consolidated statement of income
based on their fair value.  SFAS No. 123(R) also  requires  entities to estimate
the number of  forfeitures  expected to occur and record  expense based upon the



                                       7


number of awards  expected to vest. The Company  implemented  SFAS No. 123(R) on
January  1,  2006.  The  unamortized   portion  of  unearned   compensation  was
reclassified  to retained  earnings upon  implementation.  The  amortization  of
unearned  compensation is being recorded as additional paid-in capital effective
January  1, 2006.  The  implementation  of SFAS No.  123(R) had no effect on the
Company's results of operations for the three months ended March 31, 2006.

Note 9.   Commitments and Contingencies

     The Company is party to ordinary,  routine  litigation  and  administrative
proceedings  incidental  to its  business.  In the  opinion of  management,  the
Company's  potential  exposure  under  pending legal  proceedings  is adequately
provided for in the accompanying consolidated financial statements.

     The  Company  had  commitments  at March 31,  2006 to acquire  new  revenue
equipment  for  approximately  $50.3  million  in 2006.  These  commitments  are
expected to be financed  from  existing  cash and  investment  balances and cash
flows from operations.

     The  Company  announced  on March  10,  2006  that our  Board of  Directors
declared a regular quarterly dividend of $.02 per common share, payable on April
3, 2006, to stockholders of record on March 23, 2006.

     The Company  announced on September 22, 2005 the planned  construction of a
new corporate  headquarters and an adjacent shop facility.  These new facilities
will be  funded  with  the  proceeds  from  the  sale of the  current  corporate
headquarters. Construction is expected to be completed in the spring of 2007.

Note 10.  Related Party Transactions

     The Company  leases two office  buildings  and a storage  building from its
president  under a lease which provides for monthly  rentals of $27,618 plus the
payment of all property taxes, insurance and maintenance.  The lease was renewed
for a five year term on June 1, 2005  increasing the monthly rental from $24,969
to $27,618. In the opinion of management, the rates paid are comparable to those
that could be negotiated with a third party.

     Rent expense paid to the Company's  president  totaled  $82,854 and $74,906
for the three months ended March 31, 2006 and 2005,  respectively.  In 2005, the
Company  announced the  construction  of a new corporate  headquarters  which is
expected to be ready for occupancy in 2007.  The lease will be canceled upon the
occupancy of the new corporate headquarters and shop facility.

     During the quarter ended March 31, 2006,  the Company  purchased 16.7 acres
of land in North  Liberty  from the  Company's  president  for  $1,250,000.  The
purchase price was based on the fair market value that could be obtained from an
unrelated third party on an arm's length basis.  The transaction was approved by
the Board of Directors.

Note 11.  Reclassifications

     Certain  reclassifications  have been made to the  prior  period  financial
statements to conform to the March 31, 2006 presentation.

Note 12. Subsequent Event

     The  Company's  board of directors  approved a  four-for-three  stock split
payable in the form of a 33 percent stock  dividend.  The stock dividend will be
paid on May 15, 2006 to  stockholders of record as of May 5, 2006. The Company's
issued and outstanding shares of common stock will increase from 73.8 million to
98.4 million upon effect of the stock dividend.

Overview

     Heartland Express,  Inc. is a short-to-medium  haul truckload carrier.  The
Company  transports freight for major shippers and generally earns revenue based
on the number of miles per load delivered. The Company provides regional dry van
truckload  services  from eight  regional  operating  centers plus its corporate
headquarters. The Company's eight regional operating centers accounted for 63.4%
of the first  quarter  2006  operating  revenues.  The  Company  expanded to the
Western  United  States in the  second  quarter  of 2005 with the  opening  of a
regional  operating center in Phoenix,  Arizona.  The Company takes pride in the
quality  of  the  service  that  it  provides  to its  customers.  The  keys  to
maintaining a high level of service are the availability of late-model equipment
and experienced drivers.

     Operating  efficiencies  and cost controls are achieved  through  equipment
utilization,  operating a fleet of late model equipment, maintaining an industry
leading driver to non-driver  employee  ratio,  and the effective  management of
fixed and variable  operating  costs.  At March 31, 2006, the Company's  tractor
fleet had an average age of 1.6 years while the trailer fleet had an average age
of 3.2 years. The Company has grown  internally by providing  quality service to
targeted  customers  with a high  density of freight in the  Company's  regional
operating  areas.  In  addition to the  development  of its  regional  operating
centers,  the Company has made five  acquisitions  since 1987.  Future growth is
dependent upon several  factors  including the level of economic  growth and the
related  customer  demand,  the  available  capacity in the  trucking  industry,
potential of  acquisition  opportunities,  and the  availability  of experienced
drivers.

     The  Company  ended the first  quarter of 2006 with  operating  revenues of
$135.0  million,  including fuel  surcharges,  net income of $19.7 million,  and
earnings per share of $0.27 on average  outstanding shares of 73.8 million.  The
Company posted a 79.2%  operating ratio  (operating  expenses as a percentage of
operating  revenues) and a 14.6% net margin.  The Company ended the quarter with
cash,  cash  equivalents,  and  short-term  investments  of $321.7 million and a
debt-free balance sheet. The Company had total assets of $609.3 million at March
31,  2006.  The  Company  achieved  a return  on assets of 13.2% and a return on
equity of 17.9%, both improvements over the first quarter of 2005. The Company's
cash flow from  operations for the quarter of $39.7 million  represented a 20.7%
increase over the first quarter of 2005.

     The Company hires only experienced  drivers with safe driving  records.  In
order to attract and retain experienced drivers who understand the importance of
customer  service,  the Company  increased pay for all drivers in the past three
consecutive years including an increase in 2006.  Effective October 2, 2004, the
Company began paying all drivers an  incremental  amount for miles driven in the


                                       9


upper Northeastern  United States. The Company has solidified its position as an
industry leader in driver compensation with these aforementioned  increases. The
driver pay increases in 2006 are for selected  regional  operations  including a
fleet-wide  incentive  to maintain a hazardous  materials  endorsement  on their
commercial driver's license.

     The Company has been  recognized as one of the Forbes  magazine's "200 Best
Small  Companies in America"  fourteen  times in the past nineteen years and for
the past four  consecutive  years  including  2005.  The  Company  has paid cash
dividends over the past eleven consecutive quarters. The Company became publicly
traded in November,  1986 and is traded on the NASDAQ  National Market under the
symbol HTLD.

     The  following is a discussion  of the results of operations of the quarter
ended  March 31, 2006  compared  with the same period in 2005 and the changes in
financial condition through the first quarter of 2006.

     Operating revenue increased $16.3 million (13.8%), to $135.0 million in the
first  quarter of 2006 from  $118.7  million in the first  quarter of 2005.  The
increase in revenue resulted from the Company's expansion of its fleet, improved
freight rates, and improved utilization of fleet capacity. Operating revenue for
both periods was positively  impacted by fuel surcharges  assessed to customers.
Fuel  surcharge  revenue  increased  $6.8 million to $16.9  million in the first
quarter of 2006 from $10.1 million in the first quarter of 2005.

     Salaries,  wages,  and benefits  increased  $3.7 million  (8.6%),  to $46.4
million in the first  quarter of 2006 from $42.7 million in the first quarter of
2005. These increases were the result of increased  reliance on employee drivers
due to a  decrease  in the number of  independent  contractors  utilized  by the
Company and a driver pay increase.  During the first  quarter of 2006,  employee
drivers  accounted  for 93% and  independent  contractors  7% of the total fleet
miles,  compared with 90% and 10%,  respectively,  in the first quarter of 2005.


                                       10


The Company  implemented  an increase in driver pay during the first  quarter of
2006. All drivers maintaining a valid hazardous  materials  endorsement on their
commercial  driver's license received a $0.01 per mile increase in January 2006.
Additional  increases  were given to drivers in  selected  regional  operations.
Workers'  compensation expense decreased $0.2 million (15.4%) to $1.1 million in
the quarter  ended  March 31,  2006 from $1.3  million in for the same period in
2005 due to a decrease in  frequency  and severity of claims.  Health  insurance
expense  increased $0.3 million  (15.0%) to $2.3 million in the first quarter of
2006 from $2.0 million in first  quarter of 2005 due to an increase in frequency
and severity of claims and increased reliance on employee drivers.

     Rent and purchased  transportation  decreased $1.5 million (19.6%), to $6.2
million in the first  quarter of 2006 from $7.7 million in the first  quarter of
2005.  This  reflects  the  Company's   decreased   reliance  upon   independent
contractors. Rent and purchased transportation for both periods includes amounts
paid to independent  contractors under the Company's fuel stability program. The
Company  increased the independent  contractor base mileage pay by $.01 per mile
in the first  quarter  of 2006 for all  independent  contractors  maintaining  a
hazardous materials endorsement on their commercial driver's license.

     Fuel  increased  $7.4 million  (28.9%) to $33.0  million in 2006 from $25.6
million  in 2005.  The  increase  is the result of  increased  fuel  prices,  an
increased  reliance on  company-owned  tractors,  and a decrease in fuel economy
associated with the EPA-mandated clean air engines.  The Company's fuel cost per
company-owned  tractor mile increased 22.1% in first quarter of 2006 compared to
2005.  Fuel cost per mile,  net of fuel  surcharge,  decreased 1.6% in the first
quarter of 2006 compared to 2005. The Company's  fuel cost per gallon  increased
21.6% in 2006 compared to 2005.  In the quarter  ended March 31, 2006,  tractors
with the  EPA-mandated  clean  air  engine  accounted  for  70.0%  of the  miles
generated  by the  company-owned  fleet  compared to 32.5% of the  company-owned
fleet in the 2005 period.  Fuel economy for tractors with EPA-mandated clean air
engines decreased 5.4%.

     Operations and  maintenance  increased $0.4 million (14.6%) to $2.9 million
in the first quarter of 2006 from $2.5 million in the first quarter of 2005. The
increase is primarily  attributable to the growth of the  company-owned  tractor
and trailer fleets and the associated costs to maintain revenue equipment.

     Insurance and claims increased $1.3 million (44.3%), to $4.1 million in the
first  quarter of 2006 from $2.8 million in the first  quarter of 2005 due to an
increase in the frequency and severity of claims.

     Depreciation  increased $1.8 million  (21.3%),  to $10.2 million during the
first  quarter  of 2006 from $8.4  million in the first  quarter  of 2005.  This
increase is attributable to the growth of our company-owned  tractor and trailer
fleet,  an  increased  cost  of  new  tractors  primarily  associated  with  the
EPA-mandated  clean air  engines,  and the  implementation  of SFAS No. 153. New
tractors have a higher cost than the models being  replaced due to  EPA-mandated
clean air standards.  As of March 31, 2006, 71.3% of the Company's tractor fleet
had the EPA clean  air  engine  compared  to 34.1% at March  31,  2005.  For the
quarter  ended  March 31,  2006,  implementation  of SFAS No.  153  resulted  in
approximately  $0.4  million of  additional  depreciation  as a result of higher
depreciable basis of revenue  equipment  acquired through  trade-ins.  In future
periods,  we expect  depreciation  will  increase  as we continue to upgrade our
fleet in compliance  with  EPA-mandated  engine changes and due to the impact of
SFAS No. 153.

     Other operating  expenses were flat at $4.2 million in the first quarter of
2006  and  2005.  Other  operating  expenses  consists  of  costs  incurred  for
advertising  expense,   freight  handling,   highway  tolls,  driver  recruiting
expenses, and administrative costs.

     Gain on the  disposal of property  and  equipment  increased  $2.9  million
(1587.0%) to $3.1 million  during the first quarter of 2006 from $0.2 million in
the first quarter of 2005. For 2006, $3.0 million  represents gains on trade-ins
of revenue equipment which are recognized currently under of SFAS No. 153. These
gains were previously  deferred as a reduction of the  depreciable  basis of new
revenue equipment.

                                       11


     Interest  income  increased  $1.2 million  (87.7%),  to $2.5 million in the
first quarter of 2006 from $1.3 million in the same period of 2005. The increase
is the  result  of  higher  average  balances  of cash,  cash  equivalents,  and
short-term investments and higher yields than 2005.

     The Company's effective tax rate was 35.5% in the first quarter of 2006 and
2005.

     As a result of the  foregoing,  the Company's  operating  ratio  (operating
expenses  as a  percentage  of  operating  revenue)  was 79.2%  during the first
quarter of 2006 compared with 81.4% during the first quarter of 2005. Net income
increased  $4.6 million  (30.8%),  to $19.7 million  during the first quarter of
2006 from $15.1 million during the first quarter of 2005.

Liquidity and Capital Resources

     The growth of the Company's business has required  significant  investments
in new revenue equipment.  Historically the Company has been debt-free,  funding
revenue equipment  purchases with cash flow provided by operations.  The Company
also obtains tractor capacity by utilizing independent contractors,  who provide
a  tractor  and  bear all  associated  operating  and  financing  expenses.  The
Company's primary source of liquidity for the three months ended March 31, 2006,
was net cash provided by operating activities of $39.7 million compared to $32.9
million in the corresponding 2005 period.

     Capital   expenditures  for  property  and  equipment,   primarily  revenue
equipment net of  trade-ins,  totaled $4.6 million for the first three months of
2006  compared  to $2.0  million  for the  same  period  in  2005.  The  Company
anticipates  new  tractor  and  trailer  purchases,   net  of  trades,  totaling
approximately $57.3 million in 2006. In addition, the Company may buy additional
tractors prior to phase two of the federally mandated engine emissions standards
that will become effective in January 2007. In addition,  the Company expects to
begin  construction  of a new  facility  in Phoenix,  Arizona  during the second
quarter of 2006.

     The Company paid cash  dividends of $1.5 million in the first  quarter 2006
and 2005.  The Company began paying cash dividends in the third quarter of 2003.
The Company  declared a $1.5  million  cash  dividend in March 2006,  payable on
April 3, 2006.

     Management  believes the Company has adequate liquidity to meet its current
and  projected  needs.  The Company will  continue to have  significant  capital
requirements over the long term. Future capital  expenditures are expected to be
funded  by cash  flow  provided  by  operations  and from  existing  cash,  cash
equivalents,  and  short-term  investments.  The Company  ended the quarter with
$321.7 million in cash,  cash  equivalents,  and short-term  investments  and no
debt.  Based on the Company's  strong financial  position,  management  believes
outside financing could be obtained, if necessary, to fund capital expenditures.

Off-Balance Sheet Transactions

         The Company's liquidity is not materially affected by off-balance sheet
transactions.

Risk Factors

     You should  refer to Item 1A of our annual  report (Form 10-K) for the year
ended December 31, 2005,  under the caption "Risk Factors" for specific  details
on the  following  factors  that are not within the  control of the  Company and
could affect our financial results.

     o    Our business is subject to general  economic and business factors that
          are largely out of our control.
     o    Our growth may not continue at historic rates.
     o    Increased prices, reduced productivity, and restricted availability of
          new revenue equipment may adversely affect our earnings and cash flow.
     o    If fuel prices increase significantly, our results of operations could
          be adversely affected.
     o    Difficulty  in  driver  and  independent  contractor  recruitment  and
          retention may have a materially adverse effect on our business.


                                       12


     o    We operate in a highly  regulated  industry,  and  increased  costs of
          compliance  with, or liability for violation of, existing  regulations
          could have a materially adverse effect on our business.
     o    Our  operations  are  subject  to  various   environmental   laws  and
          regulations, the violations of which could result in substantial fines
          or penalties.
     o    We may not make acquisitions in the future, or if we do, we may not be
          successful in integrating the acquired company,  either of which could
          have a materially adverse effect on our business.
     o    If we are unable to retain our key  employees  or find,  develop,  and
          retain service center managers, our business, financial condition, and
          results of operations could be adversely affected.
     o    We are highly dependent on a few major  customers,  the loss of one or
          more of which could have a materially adverse effect on our business.
     o    Seasonality   and  the  impact  of  weather   affect  our   operations
          profitability.
     o    Ongoing insurance and claims expenses could  significantly  reduce our
          earnings.
     o    We are dependent on computer and communications systems, and a systems
          failure could cause a significant disruption to our business.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

     The Company purchases only high quality, liquid investments.  Primarily all
investments  as of March 31,  2006 have an original  maturity or interest  reset
date of twelve months or less. Due to the short term nature of the  investments,
the Company is exposed to minimal  market risk  related to its cash  equivalents
and investments.

     The Company had no debt outstanding as of March 31, 2006 and therefore, had
no market risk related to debt.

     As of March 31, 2006,  the Company did not have any long-term fuel purchase
contracts, and had not entered into any other hedging arrangements, that protect
against fuel price  increases.  Volatile  fuel prices will continue to impact us
significantly.  A  significant  increase in fuel costs,  or a shortage of diesel
fuel, could materially and adversely affect our results of operations.

Item 4.  Controls and Procedures

     As of the end of the period covered by this report, the Company carried out
an evaluation, under the supervision and with the participation of the Company's
management,  including the Company's Chief Executive Officer and Chief Financial
Officer,  of the  effectiveness  of the design and  operations  of the Company's
disclosure  controls  and  procedures,  and as  defined  in  Exchange  Act  Rule
15d-15(e). Based upon that evaluation, the Company's Chief Executive Officer and
Chief Financial  Officer  concluded that the Company's  disclosure  controls and
procedures are effective in enabling the Company to record,  process,  summarize
and report  information  required to be included in the  Company's  periodic SEC
filings  within  the  required  time  period.  There have been no changes in the
Company's  internal  controls over financial  reporting that occurred during the
Company's  most  recent  fiscal  quarter  that has  materially  affected,  or is
reasonably  likely to materially  affect,  the Company's  internal  control over
financial reporting.

Exhibit No. 31.1

                                  Certification

I,  Russell  A.  Gerdin,  Chairman,  President  and Chief  Executive  Officer of
Heartland Express, Inc., certify that:

     1.   I have  reviewed  this  quarterly  report  on Form  10-Q of  Heartland
          Express, Inc. (the "Registrant");

     2.   Based on my  knowledge,  this  report  does  not  contain  any  untrue
          statement  of a  material  fact  or  omit to  state  a  material  fact
          necessary to make the statements  made, in light of the  circumstances

     4.   The registrant's  other  certifying  officer and I are responsible for
          establishing  and maintaining  disclosure  controls and procedures (as
          defined in Exchange Act Rules  13a-15(e) and  15d-15(e))  and internal

                                  Certification

I, John P.  Cosaert,  Executive  Vice  President,  Chief  Financial  Officer and
Treasurer of Heartland Express, Inc., certify that:

     1.   I have  reviewed  this  quarterly  report  on Form  10-Q of  Heartland
          Express, Inc. (the "Registrant");

     2.   Based on my  knowledge,  this  report  does  not  contain  any  untrue
          statement  of a  material  fact  or  omit to  state  a  material  fact
          necessary to make the statements  made, in light of the  circumstances
          under which such  statements were made, not misleading with respect to
          the period covered by this report;

     3.   Based on my knowledge,  the financial  statements and other  financial
          information  included in this report,  fairly  present in all material
          respects the financial condition, results of operations and cash flows
          of the  registrant  as of,  and for,  the  periods  presented  in this
          report;

     4.   The registrant's  other  certifying  officer and I are responsible for
          establishing  and maintaining  disclosure  controls and procedures (as
          defined in Exchange Act Rules  13a-15(e) and  15d-15(e))  and internal
          control  over  financial  reporting  (as defined in Exchange  Act Rule
          13a-15(f) and 15d-15(f)) for the registrant and have:

          a)   Designed such disclosure controls and procedures,  or caused such
               disclosure  controls  and  procedures  to be  designed  under our
               supervision,  to ensure that material information relating to the
               registrant,  including  its  consolidated  subsidiaries,  is made
               known to us by others within those entities,  particularly during
               the period in which this quarterly report is being prepared;

          b)   Designed such internal control over financial reporting, or cause
               such disclosure  controls and procedures to be designed under our
               supervision,   to  provide  reasonable  assurance  regarding  the
               reliability  of  financial   reporting  and  the  preparation  of
               financial  statements  for external  purposes in accordance  with
               generally accepted accounting principles;

          c)   Evaluated  the  effectiveness  of  the  registrant's   disclosure
               controls  and   procedures  and  presented  in  this  report  our
               conclusions   about  the   effectiveness   of  the  controls  and
               procedures,  as of the end of the period  covered by this  report
               based on such evaluation; and

          d)   Disclosed in this report any change in the registrant's  internal
               control  over  financial   reporting  that  occurred  during  the
               registrant's  first fiscal quarter that has materially  affected,
               or is reasonably  likely to materially  affect,  the registrant's
               internal control over financial reporting; and

     5.   The registrant's other certifying officer and I have disclosed,  based
          on our most recent  evaluation  of  internal  control  over  financial
          reporting,  to the  registrant's  auditors and the audit  committee of
          registrant's  board of directors (or persons performing the equivalent
          functions):

          (a)  all  significant  deficiencies  and  material  weaknesses  in the
               design or operation of internal control over financial  reporting
               which are reasonably  likely to adversely affect the registrant's
               ability  to  record,  process,  summarize  and  report  financial
               information;  and

          (b)  any fraud,  whether or not material,  that involves management or
               other employees who have a significant  role in the  registrant's
               internal control over financial reporting.
