                             REGISTRATION AGREEMENT
                   (PIGGYBACK AND DEMAND REGISTRATION RIGHTS)

                                    PARTIES:

     This  Agreement is made and entered by and between  KNIGHT  TRANSPORTATION,
INC., an Arizona  corporation (the "Company"),  and ACTION DELIVERY  SERVICE,  a
Texas  corporation  ("ADS"),  ACTION  WAREHOUSE  SERVICES,  a Texas  corporation
("AWS") and BOBBY R. ELLIS and FRANCES ELLIS,  husband and wife ("Ellis").  ADS,
AWS and Ellis are hereinafter referred to as "Sellers" or the "Shareholders."

                                 EFFECTIVE DATE:

     This  Agreement is entered into and is effective as of  March 13, 1999 (the
"Effective Date").

                                    RECITALS:

     Sellers  have  agreed to sell to the  Company  certain of  Sellers'  assets
pursuant to an Asset Purchase and Sale Agreement dated as of March 15, 1999 (the
"Asset Purchase Agreement").  In consideration of Sellers' sale of the assets to
the Company,  the Company has agreed to deliver to Sellers  97,561 shares of the
Company's Common Stock, par value $0.01 per share (the "Shares").

     The Company is a publicly  reporting  company  under  Section  12(g) of the
Securities Exchange Act of 1934 and its Shares are traded on the NASDAQ National
Market.

     Each Seller is a  sophisticated  person and has had access to all  publicly
available information concerning the Company.

     The Company and the Sellers  wish to set forth the terms  pursuant to which
Sellers are  accepting  the Shares and wish to provide for certain  registration
rights  which accrue to Sellers with respect to the Shares and which the Company
hereby grant sellers.

                                   AGREEMENT:

     NOW, THEREFORE, the parties agree, as follows:

     Section 1. Information  Provided to Sellers. The Sellers have received from
the Company  copies of (i) its most recent reports filed with the Securities and
Exchange  Commission ("SEC") on Form 10-K and the quarterly reports filed by the
Company with the SEC on Form 10-Q,  and the  Company's  most recent  Information
Statement.  The Sellers have had an  opportunity  to ask  questions  and receive
answers concerning the Company,  its organization,  business and prospects.  The
Sellers are familiar with the Company,  its business,  properties  and financial
condition.  Sellers  acknowledge  that  information  concerning  the  Company is
available  publicly,  through  the SEC,  through  various  Internet  sources and
brokerage  houses.  Each of the  Sellers  represents  that it is an  "accredited
investor" (as defined in Section 2(15) of the Securities Act of 1933 (the "Act")
and Rule 501 of  Regulation  D  promulgated  thereunder,  and that it has had an
opportunity  to fully  analyze and  evaluate  the risks of  proceeding  with the
transaction  contemplated by the Asset Purchase Agreement,  and that it is fully
capable of evaluating the risks and merits of the  transaction and has consulted
with  its  professional  and  financial   advisors  regarding  the  transactions
contemplated  by the Asset Purchase  Agreement.  Sellers and their advisors have
substantial  experience in evaluating  businesses  such as the Company.  Each of
Sellers agree that the Shares are acquired for  investment  only and will not be
sold or  distributed,  unless  registered in accordance  with  applicable law or
unless an exemption from  registration is available,  in the opinion of counsel,
acceptable to the Company or sale of the Shares is effected  under SEC Rule 144.
Seller  understands  that a legend to that  effect will be placed on the Shares.
Each of  Sellers  represents  and  warrants  that in  accepting  the  Shares  as
consideration under the Asset Purchase Agreement, the Sellers have relied solely
upon the public  information  about the Company and that the Company has made no
other representations or warranties to Sellers,  other than are set forth in the
Asset Purchase Agreement. Sellers acknowledge that the Shares delivered by Buyer
have not been registered with the SEC, and that the Company's only obligation to
register such shares is set forth in this Registration Agreement.

     Section 2. Registration Under The Securities Act of 1933.

          (a) Piggyback  Rights.  If the Company files a registration  statement
under the Act, which relates to a current  offering of equity  securities of the
Company  (except  in  connection  with  an  offering  of  the  Company's  equity
securities to its employees pursuant to any employee benefit or any stock option
plan,  or any  dividend  reinvestment  plan  maintained  by the  Company),  such
registration statement and the prospectus included therein shall, at the written
request of the Shareholders, include, subject to any underwriter requirements or
cutbacks,  all or part  of the  Shares  owned  by such  Shareholders  under  the
registration  statement  so as to permit  the  public  sale of the Shares by the
Shareholders  in compliance  with the Act. The Company shall give written notice
to the Shareholders of its intention to file a registration  statement under the
Act  relating to an offering of its equity  securities  not less than sixty (60)
days  prior to the  filing of such  registration  statement  with the SEC or any
successor in interest. The Shareholders' written request to the Company that all
or a portion of their Shares be included in the registration  statement, if made
not later than thirty (30) days prior to the date specified in the notice as the
date on which the  Company  intends to file its  registration  statement,  shall
allow the  Shareholders  to  register  all or part of their  Shares  under  such
registration statement. Neither the Company's delivery of notice nor delivery of
a request by

                                       -2-

any Shareholder for  registration  shall in any way obligate the Company to file
such registration statement and, notwithstanding the filing of such registration
statement,  the Company may, at any time prior to the  effective  date  thereof,
determine  not to offer the  securities  to which  such  registration  statement
relates, without liability to the Shareholders, except in that event the Company
shall pay all expenses of the registration  statement  incurred through the date
the registration  statement is withdrawn.  The Company shall pay the entire cost
of any  registration  of Shares to which this  Section 2(a)  applies,  including
without limitation,  attorneys' fees,  accounting fees, filing fees and printing
costs, but excluding any underwriter's  discount;  provided,  however,  that the
Shareholders  shall be solely  responsible for any underwriter  discounts on any
Shares sold by the Shareholders pursuant to any registration  statement filed by
the  Company  and  for the  Shareholders'  pro  rata  share  of any  underwriter
expenses.  A  Shareholder  who  exercises  his rights  under this  Agreement  is
sometimes referred to herein as a "Selling Shareholder."

          (b)  Demand   Rights.   Upon  written   notice  to  the  Company  (the
"Registration  Demand"),  at any time  beginning  eleven (11)  months  after the
Effective Date and within the three (3) year(s)  period  following the Effective
Date  hereof,  given (i) by Sellers or (ii) by Ellis or at least two  persons to
whom the Shares have been  transferred  from ADS, or AWS or Ellis  (individually
and collectively, the "Selling Shareholders"), that such persons contemplate the
sale or  transfer  of all or part of the  Shares  under  circumstances  that may
require registration of such shares under the Act, the Company shall, at its own
expense, as promptly as possible after receipt of such Registration Demand, file
with the SEC a  registration  statement  pursuant to Section 5 of the Act on the
appropriate  registration  form,  with  respect  to the offer and sale (or other
disposition)  of the  Shares for which the  Company  shall  have  received  such
Registration  Demand.  Within  thirty (30)  business  days after  receiving  the
Registration  Demand, the Company shall notify all the Selling  Shareholders and
advise them that the  Company is  proceeding  with the filing of a  registration
statement  (or  notification)  and  the  Company  shall  offer  to  include  for
registration  under such registration  statement (or notification) the Shares of
those Selling  Shareholders.  The Company shall not be obligated to register the
Shares of any such Selling  Shareholder  unless such other  Selling  Shareholder
accepts the  Company's  offer of  registration  in writing  within ten (10) days
after such offer is made. A Selling Shareholder shall make only one registration
demand in any calendar year. The Company shall take all action necessary to file
such registration  statement and cause it to become effective within one hundred
twenty (120) days after receipt of said Registration Demand.  Except as provided
below, the cost of such registration  statement  (including any attorneys' fees,
accounting  fees and  underwriters'  fees) shall be borne  solely by the Selling
Shareholders  whose Shares are registered,  on a pro rata basis in proportion to
the Shares owned by each Selling Shareholder, if the Company elects not to offer
any  Shares  for its own  account  pursuant  to the  registration  statement  or
notification;  provided  that if the Company  includes any of its Shares in such
registration statement or notification,  the Company shall pay all costs of such
registration,   other  than  the  underwriter's  discount  and  any  underwriter
expenses.  Any provision of this Section 2 notwithstanding,  if any registration
demand  is  made  by  Ellis,  the  Company  agrees  to pay  all  costs  of  such
registration,  without regard to whether the Company is  registering  Shares for
sale on its own account,  but Ellis shall be responsible  for any  underwriter's
discount and underwriter's expenses.

                                       -3-

If only the Shares of the Selling Shareholders are included in such notification
or  registration  statement,  no Shares of the Company shall be registered for a
period of 90 days following the date offering of the Shares is completed. Demand
registration  rights under this Section 2(b) shall terminate on the day prior to
the third anniversary of the Effective Date.

          (c) In each  instance in which,  pursuant  to Section  2(a) or 2(b) of
this Section 2, the Company shall take any action to permit a public offering or
sale, or other distribution of the Shares, the Company shall:

               (i)  keep  effective  until  the  earlier  of (A)  the  date  all
          registered  Shares are sold or (B) two hundred and seventy  (270) days
          after the initial  effective date of such  registration  statement (or
          notification),  and take such other action as may be necessary to keep
          effective (and pay all expenses  related to) such other  registrations
          and qualifications (including those required by the securities laws of
          any state in which the Shares are offered or sold), and do any and all
          other acts and  things  necessary  to permit the public  sale or other
          disposition of the Shares by such Selling Shareholders.

               (ii)  indemnify and hold harmless  each  underwriter,  within the
          meaning  of  the  Act,  to the  extent  required  by any  underwriting
          agreement or, if greater, to the extent required by this Agreement.

               (iii) indemnify and hold harmless each Selling Shareholder to the
          extent required in any underwriting  agreement or, if greater,  to the
          extent provided in this Agreement.

          (d) For purposes of this Section 2, the term "equity securities" means
any class or series of common or preferred stock of the Company.

          (e) If any Shares  registered under this Agreement are offered through
an  underwriter,  each  Selling  Shareholder  and the Company each agrees (i) to
execute any underwriting  agreement  requested by the underwriter,  (ii) furnish
any indemnity in the customary form required by the  underwriter,  (iii) furnish
any  information  required by the  underwriter,  and (iv) take any other  action
reasonably  necessary  to satisfy the  underwriting  conditions  or to cause the
registration   statement  to  become  effective.   The  rights  of  any  Selling
Shareholder  under this  Agreement  shall be subject to and limited by the terms
and  conditions  of  any  indemnity  agreement  and  any  other  conditions  the
underwriter may impose. The failure of a Selling  Shareholder to comply with the
provision of this Section 2(e) shall  relieve the Company of the  obligation  to
register the Shares as provided by this Agreement.

                                       -4-

     Section 3. Compliance With Law.

     Any  registration  statement filed by the Company pursuant to the Act shall
comply in all  respects  with the Act and all rules and  regulations  of the SEC
applicable  to such  registration  statement.  At such time as any  registration
statement (or notice) becomes effective, the Company shall supply to the Selling
Shareholders and to any person or underwriter acting on their behalf, sufficient
copies of the prospectus used in connection with the registration  statement for
the Selling  Shareholder to sell publicly the registered Shares. With respect to
any  registration  of Shares  subject to this  Agreement,  the  Company,  at its
expense,  agrees to  qualify  or  register  the Shares in any state in which the
Selling Shareholder requests that the Shares be qualified or registered,  to the
extent  that the  Company is  reasonably  able to do so, and the  Company  shall
maintain  such  qualification  or  registration  in  effect  for so  long as the
registration statement is in effect.

     Section  4.  Selling   Shareholders'  Consent  and  Obligation  to  Furnish
Information.

     The  Selling  Shareholders  shall  promptly  provide  to the  Company  such
consents and  information as may be reasonably  required by the Company in order
to perform  its  obligations  under  Section 1 hereof.  It shall be a  condition
precedent  to the  obligations  of the  Company to take any action  pursuant  to
Section  2(a),  2(b),  2(c),  7(a) or 7(b) that the Selling  Shareholders  shall
furnish to the Company such information  regarding the Selling  Shareholders and
the  Shares  held by  them,  and the  intended  method  of  disposition  of such
securities as shall be required to effect the registration of the Shares.

     Section 5. "Market Stand-Off" Agreement.

     The Selling  Shareholders agree that they will not, to the extent requested
by the Company and an underwriter,  sell or otherwise transfer or dispose of any
Shares  (other than Shares being  registered  in such  offering)  for up to that
period of time following the effective  date of a registration  statement of the
Company  filed under the Act as is requested by the managing  underwriter(s)  of
such  offering.  The Company agrees that any lock-up  agreement  obtained by the
underwriter with respect to the Selling  Shareholders will be no longer than any
similar agreement applicable to the Company in connection with any Shares of the
Company registered by the Company pursuant to such registration  statement.  The
Selling  Shareholders  agree to execute  any lock-up  agreement  required by the
managing underwriter.

     Section 6. Reports.

     In connection with any registration of its Shares, the Company at all times
will comply with the Act and will file such  reports and  disclosures  as may be
required by the Act or any rules or regulations promulgated  thereunder.  If the
Company is subject to the Securities  Exchange Act of 1934 (the "Exchange Act"),
the Company agrees to file timely all reports required by the

                                       -5-

Exchange  Act.  If the  Company is a listed  company  on NASDAQ or any  national
securities  exchange,  the Company shall file all reports  necessary to maintain
such listing.

     Section 7. Indemnification.

          (a) Company.  The Company  agrees to indemnify  and hold  harmless any
Selling  Shareholder  and any  underwriter,  to the extent  applicable,  and any
person who, within the meaning of the Act (or the Exchange Act), controls any of
such persons  (hereafter,  individually and  collectively,  the "Selling Group")
for, from, and against any losses,  claims,  damages, or liabilities,  joint and
several,  to which the Selling  Group,  or any of them, may become subject under
the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages,
or  liabilities  (or actions in respect  thereof) arise out of or are based upon
any untrue  statement or alleged untrue statement of any material fact contained
in a registration  statement,  or the prospectus which is a part thereof, or any
amendment or supplement  thereto, or arise out of or are based upon the omission
or alleged  omission to state  therein a material  fact  necessary  to be stated
therein to make the statements  therein not  misleading;  and will reimburse the
Selling  Group  and each of them,  for any  legal or other  expenses  and  costs
reasonably  incurred by them in connection with the  investigation or defense of
any such loss, claim, damage, liability, or action; provided,  however, that the
Company will not be liable under this Section 7(a) if any such loss,  claim,  or
liability  arises  solely out of or is based  solely on an untrue  statement  or
alleged  untrue   statement  or  omission  or  alleged   omission  made  in  the
registration  statement or the prospectus or any amendment or supplement thereto
in reliance upon and in  conformity  with written  information  furnished to the
Company  by or on behalf of the  Selling  Group or any of them.  A member of the
Selling Group,  who is treated as a control person under the Act or the Exchange
Act,  shall be covered by and  included  within the  indemnity  provided by this
Section 7(a) for all losses, claims, damages, liabilities, and expenses asserted
in connection with the registration statement, notice or the sale of the Shares,
whether or not based on Section 15 of the Act or Section 20 of the Exchange Act.
The  indemnity  obligation  provided  herein is in addition to any  liability or
obligation  which the Company may otherwise  have to the Selling Group or any of
them or which may exist at common law or under any applicable statute.

          (b) Selling Group.  Each member of the Selling Group,  severally,  but
not  jointly,  will  indemnify  and  hold  harmless  the  Company,  each  of its
directors,  each of its officers who signs the registration  statement,  and any
person who controls  the Company  within the meaning of the Act (or the Exchange
Act) for, from and against any losses, claims,  damages, or liabilities to which
the  Company or any such  director or officer or  controlling  person may become
subject, under the Act, the Exchange Act, or otherwise,  if such losses, claims,
damages,  or liabilities  (or actions in respect  hereof) arise solely out of or
are based solely on any untrue or alleged  untrue  statement of a material  fact
contained in the  registration  statement,  the  prospectus  or any amendment or
supplement  thereto,  or arise out of or are based upon the  omission or alleged
omission to state therein a material fact necessary to be stated therein to make
the statements therein not misleading, in each case if, and only if, such untrue
statement or alleged untrue  statement or omission or alleged  omission was made
in the registration statement, the prospectus or such amendment or supplement

                                       -6-

in reliance  upon and in conformity  with written  information  concerning  such
member of the  Selling  Group  furnished  to the Company by or on behalf of such
member  of the  Selling  Group  for use in the  registration  statement  and the
prospectus or any amendment or supplement thereto,  and will reimburse any legal
or other expense reasonably  incurred by the Company or such director or officer
or controlling  person in connection  with  investigating  or defending any such
loss, claim,  damage,  liability,  or action. This indemnity obligation provided
hereunder is in addition to any other liability or obligation  which the Selling
Group or each member of the Selling Group  separately  may otherwise have to the
Company or which may exist at common law or under any applicable statute.

          (c) Claims.  Promptly after receipt by an indemnified party under this
Section 7(c) of notice of the  commencement  of any action or the  initiation of
any proceeding  (including,  without limitation,  arbitration),  the indemnified
party will, if a claim in respect thereof is to be made against any indemnifying
party under this Section 7(c),  notify the indemnifying  party in writing of the
commencement  thereof; but the failure to notify the indemnifying party will not
relieve  it from  any  liability  which  it may  have to any  indemnified  party
otherwise than under this Section 7(c),  unless failure to notify  prejudices or
causes  material  harm to the  indemnifying  party.  In case any such  action is
brought against any indemnified  party and such  indemnified  party notifies any
indemnifying party of the commencement  thereof, the indemnifying party shall be
entitled to  participate  therein  and, to the extent that it may wish,  jointly
with any other indemnifying party similarly notified, assume the defense thereof
with counsel who shall be reasonably satisfactory to such indemnified party and,
after  notice  from  the  indemnifying  party to such  indemnified  party of its
election to so assume the defense thereof,  the  indemnifying  party will not be
liable to such indemnified  party under this Section 7(c) for any legal or other
expenses  subsequently incurred by such indemnified party in connection with the
defense  thereof  other  than  reasonable  costs of  investigation.  In any such
action,  any  indemnified  party shall have the right to retain his own counsel,
but the fees and  expenses  of such  counsel  shall  be at the  expense  of such
indemnified  party unless (i) the indemnifying  party and the indemnified  party
shall have mutually agreed to the reten tion of such counsel,  or (ii) the named
parties to any such proceeding  (including any impleaded  parties)  include both
the  indemnifying  party and the indemnified  party and  representation  of both
parties by the same counsel  would be  inappropriate  due to actual or potential
differing or conflicting  interests  between them. The indemnifying  party shall
not be liable for any settlement of any proceeding or claim effected without its
written  consent,  but if  settled  with  such  consent  or if  there is a final
judgment for the  plaintiff,  the  indemnifying  party  agrees to indemnify  the
indemnified  party for, from and against any loss or liability by reason of such
settlement  or judgment.  The  indemnified  party shall  cooperate  fully in the
defense of any claim subject to  indemnification  hereunder  and shall,  without
limiting  this  duty  of  cooperation,   make  himself  available  for  pretrial
investigation and preparation,  depositions,  and interviews by the indemnifying
party's legal counsel.

          (d) Enforceability.  If the indemnification provided in Sections 7(a),
7(b)  and  7(c),   is,  for  any  reason,   other  than  as  specified  in  such
subparagraphs,  held by a court to be unavailable  and the Company,  the Selling
Group,  or any member  thereof has been required to pay damages as a result of a
determination by a court that the preliminary  prospectus,  registration  state-

                                      -7-

ment, the prospectus,  or any amendment or supplement thereto contains an untrue
statement of a material fact or omits to state a material  fact  necessary to be
stated therein to make the statements  therein not misleading,  then the Company
shall contribute to the damages paid by the Selling Group or any member thereof,
and the Selling Group shall  contribute to the damages paid by the Company,  but
in each case only to the extent that such damages arise out of or are based upon
such untrue  statement or omission,  in such  proportion  as is  appropriate  to
reflect the relative  fault of the  Company,  the Selling  Group,  or any member
thereof in connection  with the  statements or omissions  which resulted in such
damages,  as well as any other relevant equitable  considerations.  The relative
fault shall be  determined  by  reference  to, among other  things,  whether the
untrue  statement of a material  fact or the  omission to state a material  fact
relates to information supplied by the Company, the Selling Group, or any member
thereof, and the parties' relative intent, knowledge, access to information, and
opportunity  to  correct or prevent  such  untrue  statement  or  omission.  For
purposes of this Section 7(d),  the term  "damages"  shall include any legal and
other expenses  reasonably  incurred by the Company,  the Selling Group,  or any
member  thereof in  connection  with investi  gating and defending any action or
claim which is the subject of the contribution  provisions of this Section 7(d).
No person adjudged guilty of fraudulent  misrepresentation within the meaning of
Section 11 of the Act shall be entitled to contribution  from any person who was
not adjudged guilty of such fraudulent misrepresentation.

          (e) Term. The agreements  contained in Sections 7(a) through (d) shall
remain   operative  and  in  full  force  and  effect   regardless  of  (i)  any
investigation made by or on behalf of the Selling Group or any of them, or by or
on behalf of the  Company,  any of its  directors  or  officers,  or any  person
controlling the Company, and (ii) any termination of this Agreement. A successor
of the Selling  Group,  or any of them,  or of the  Company,  or any director or
officer  thereof,  or any person  controlling  the Selling  Group or the Company
shall be entitled to the benefits of the  agreements  contained in Sections 7(a)
through (e) herein.
