                               CELADON GROUP, INC.
                       CODE OF BUSINESS CONDUCT AND ETHICS

To Whom the Code Applies

         This Code applies to all Celadon employees, including, but not limited
to, its principal executive officer; senior financial officer; principal
financial officer and controllers, or principal accounting officer; or persons
performing similar functions. Its purpose is to deter wrong doing.

The Standard of Conduct

         Celadon employees must maintain the highest standards of ethical
conduct in their work. Behaving ethically means avoiding: actual or apparent
conflicts of interest between personal and professional relationships; lying;
cheating; and stealing, as well as deception and subterfuge. Behaving ethically
also means personal compliance with all applicable governmental laws, rules, and
regulations.

         Every employee records information of some kind which is used for
business purposes. Full, fair, accurate, understandable and timely reporting of
information is critical. Any employee who falsifies, alters, or misrepresents
data, information, (including financial information), or records/accounts,
whether in a filing with an administrative agency or in a public communication,
will be severely disciplined if not discharged.

Reporting Misconduct

         The duty and responsibility to accurately and honestly report
information and to not lie, cheat, steal or deceive extends to and includes the
duty to report those who breach this duty and responsibility and to provide
information or participate in a proceeding wherein someone is alleged to have
violated this duty and responsibility.

<PAGE>

People Who Report Misconduct Are Protected

         Employees who report unethical conduct, or who provide information in
an investigation of alleged unethical behavior, are protected against
retaliation or adverse employment actions that are taken against the employee
for reporting the unethical conduct or participating in the investigation. This
protection extends to, but is not limited to, employees who report alleged
violations of the Securities and Exchange Commission rules relating to fraud
against shareholders or any federal or state securities or anti fraud law.

To Whom Is The Report To Be Made

         If you have any reason to believe that any employee has done anything
illegal or unethical, such as dishonestly reporting information or altering
Company records, your obligation to report the behavior can be fulfilled by
calling (317) 972 - 7064 and speaking with Ken Core or leaving a recorded
message with your name and return phone number. You can also file your report by
e-mail addressed to kcore@celadontrucking.com. You will never be adversely
impacted for making such a good faith report. If you are in doubt about whether
a particular occurrence is an event you should report, you should call the same
number listed above and discuss your concern or send your inquiry to Ken Core.

Insider Trading/Access To Non-Public Information

         If you learn information that directly or indirectly relates to Celadon
or could impact its value or stock price, you must not share that information
with persons who have no business reason to know what you know. It would be
illegal for you to personally invest, or cause others (e.g., friends, relatives)
to invest for themselves or for you based on that information. Celadon has
adopted a separate Insider Trading Policy which includes, among other
provisions, specific prohibitions on trading on non-public information or
"tipping" others who might trade.

                                       2

Corporate Opportunities

         Employees, Officers and Directors must never take for themselves
personally opportunities that are discovered through the use of corporate
property, information or position. Likewise, employees, Officers, and Directors
must never use corporate property or information for personal gain or to compete
with the Company. Your work hours are to be devoted solely to activities
directly related to Celadon business. You may not perform work for or solicit
business for any other employer if it presents a conflict of interest that
detracts from the Company's goals, causes the individual's job performance to
deteriorate, or reflects in a negative way on the Company. Work or employment
for a competitor of the Company is discouraged and could be the basis for
immediate discharge. Any employee seeking outside work or employment must have
it approved by their department manager before commencing the work or
employment.

Proper Use Of Company Assets

         All Company assets, (e.g., phones, computers, etc.) should be used
solely for legitimate business purposes. Carelessness and waste are as
unacceptable as theft.

Proprietary And/Or Confidential Information

         Proprietary information is sensitive, confidential, private or
classified technical, financial, personnel or business information. This
includes trade secrets. You must not misuse or disclose such information to
non-employees of Celadon (including family and friends). This obligation on your
part not to disclose or misuse Celadon proprietary/confidential information
continues when and if you leave Celadon for whatever reason.

Relationships With Customers/Suppliers

         You must treat all customers/suppliers fairly and according to
applicable laws, customs and regulations. Business decisions regarding suppliers
must be made on the basis of the quality,

                                       3

<PAGE>

delivery, value and reliability of the product or service offered. Employees may
not borrow money or accept advances or other personal payments or gifts,(1)
including gifts of entertainment, from any person or company doing or seeking to
do business with Celadon.

         1.       Business dining as a guest of a supplier should not occur
         unless approved in advance by the immediate supervisor of the Company.

         2.       Travel and overnight accommodations paid for by a supplier are
         not allowed.

         3.       Travel in a supplier/customer plane must have the
         recommendation of the immediate supervisor and the prior written
         approval of an Officer of the Company.

         When doing business with federal, state or local governmental
customers, Celadon employees may never offer any favors or gratuities to the
customer. This prohibition includes purchasing meals for the customer or
providing the customer even minor amenities. Most governmental customers have a
zero tolerance policy as regards soliciting or accepting favors or gratuities
and this Celadon Policy is intended to avoid what could otherwise become
embarrassing situations for the customer and become a reason for the customer
terminating its business relationship with Celadon.

Conflicts of Interest

         A "conflict" occurs when an individual's private interest interferes or
even appears to interfere in any way with the person's professional
relationships and/or the interests of Celadon. You are conflicted if you take
actions or have interests that may make it difficult for you to

------------------------
(1) Gifts reasonably valued at $100.00 or less or given in conjunction with a
holiday which can be shared

                                       4

<PAGE>

perform your work for the Company objectively and effectively. Likewise, you are
conflicted if you or a member of your family receives improper personal benefits
as a result of your position in the Company (directly or through a company they
are employed by or in which they have an ownership interest). If you think you
have been, are, or may become conflicted, report the situation to Ken Core or by
e-mail to kcore@celadontrucking.com immediately. The prompt reporting of such
situations will be favorably weighted should it be determined that corrective
actions need to be administered.

Waivers/Changes

         No waivers or changes in any provisions of this Code of Business
Conduct and Ethics can be granted by any person other than the Chairman and
Chief Executive Officer of Celadon or a member of the Board of Directors. Any
waiver or change will be in writing and will be promptly disclosed to the
public, in accordance with rules applicable to public companies like Celadon.
Public disclosure will be made within two (2) business days after the waiver is
granted or change is made. It will be made by the filing of a Securities and
Exchange Commission Form 8-K. Concurrently, notice will be made by a posting on
the Company website, which posting will be retained for at least 12 months after
it is initially posted.

Accountability

         Violations of this Code of Business Conduct and Ethics will result in
discipline up to and including termination and/or civil and/or criminal
prosecution.

and consumed by employees while at work (e.g., baskets of fruit, cheese) are not
prohibited under this policy.

fractionalization thereof in whole or in part and no other person has a direct
or indirect beneficial interest in such Securities. Further, the Investor does
not have any contract, undertaking, agreement or arrangement with any personal
to sell, transfer or grant participations to such person or to any third person,
with respect to any of the Securities.

                           (vi) The Investor acknowledges the Investor's
understanding that the offering and sale of the Securities is intended to be
exempt from registration under the 1933 Act by virtue of Section 3(b) of the
1933 Act and the provisions of Regulation D promulgated thereunder ("Regulation
D"). In furtherance thereof, the Investor represents and warrants as follows:

                                    (a) The Investor realizes that the basis for
the Regulation D exemption may not be present, if, notwithstanding such
representations, the Investor has in mind merely acquiring Securities for a
fixed or determinable period in the future, or for a market rise, or for sale if
the market does not rise. The Investor does not have any such intentions;

                                    (b) The Investor has the financial ability
to bear the economic risk of the Investor's investment, has adequate means for
providing for the Inventor's current needs and personal contingencies and has no
need for liquidity with respect to the Investor's investment in the Company; and

                                    (c) The Investor has such knowledge and
experience in financial and business matters as to be capable of evaluating the
merits and risks of the prospective investment. The Inventor also represents it
has not been organized for the purpose of acquiring the Securities.

                           (vii) The Investor has been given the opportunity for
a reasonable time prior to the date hereof to ask questions of, and receive
answers from, the Company or its representatives concerning the terms and
conditions of the Offering, and other matters pertaining to this investment, and
has been given the opportunity for a reasonable time prior to the date hereof to
obtain such additional information in connection with the Company in order for
the Investor to evaluate the merits and risks of purchase of the Securities, to
the extent the Company possesses such information or can acquire it without
unreasonable effort or expense. The Investor is not relying on the Placement
Agent or any of its affiliates with respect to the accuracy or completeness of
the Offering Materials or for any economic considerations involved in this
investment.

         6. CERTAIN COVENANTS AND AGREEMENTS OF THE COMPANY.

         The Company covenants and agrees at its expense and without any expense
to the Placement Agent as follows:

                  A. To advise the Placement Agent and the Investor of any
material adverse change in the Company's financial condition, prospects or
business or of any development materially affecting the Company or rendering
untrue or misleading any material statement in the

                                       7

Offering Materials occurring at any time as soon as the Company is either
informed or becomes aware thereof.

                  B. To use its commercially reasonable efforts to cause the
Common Stock issuable in connection with the Equity Line of Credit to be
qualified or registered for sale on terms consistent with those stated in the
Registration Rights Agreement and under the securities laws of such
jurisdictions as the Placement Agent and the Investor shall reasonably request.
Qualification, registration and exemption charges and fees shall be at the sole
cost and expense of the Company.

                  C. Upon written request, to provide and continue to provide
the Placement Agent and the Investor copies of all quarterly financial
statements and audited annual financial statements prepared by or on behalf of
the Company, other reports prepared by or on behalf of the Company for public
disclosure and all documents delivered to the Company's stockholders.

                  D. To deliver, during the registration period of the Equity
Line Credit Agreement, to the Investor upon the Investor's request, within forty
five (45) days, a statement of its income for each such quarterly period, and
its balance sheet and a statement of changes in stockholders' equity as of the
end of such quarterly period, all in reasonable detail, certified by its
principal financial or accounting officer; (ii) within ninety (90) days after
the close of each fiscal year, its balance sheet as of the close of such fiscal
year, together with a statement of income, a statement of changes in
stockholders' equity and a statement of cash flow for such fiscal year, such
balance sheet, statement of income, statement of changes in stockholders' equity
and statement of cash flow to be in reasonable detail and accompanied by a copy
of the certificate or report thereon of independent auditors if audited
financial statements are prepared; and (iii) a copy of all documents, reports

reports and information are furnished to its stockholders.

                  E. To comply with the terms of the Offering Materials.

                  F. To ensure that any transactions between or among the
Company, or any of its officers, directors and affiliates be on terms and
conditions that are no less favorable to the Company, than the terms and
conditions that would be available in an "arm's length" transaction with an
independent third party.

         7. INDEMNIFICATION.

                  A. The Company hereby agrees that it will indemnify and hold
the Placement Agent and each officer, director, shareholder, employee or
representative of the Placement Agent and each person controlling, controlled by
or under common control with the Placement Agent within the meaning of Section
15 of the 1933 Act or Section 20 of the 1934 Act or the SEC's Rules and
Regulations promulgated there under (the "RULES AND REGULATIONS"), harmless from
and against any and all loss, claim, damage, liability, cost or expense
whatsoever (including, but not limited to, any and all reasonable legal fees and
other expenses and disbursements incurred in connection with investigating,
preparing to defend or defending any action, suit or proceeding, including

                                       8
<PAGE>

any inquiry or investigation, commenced or threatened, or any claim whatsoever
or in appearing or preparing for appearance as a witness in any action, suit or
proceeding, including any inquiry, investigation or pretrial proceeding such as
a deposition) to which the Placement Agent or such indemnified person of the
Placement Agent may become subject under the 1933 Act, the 1934 Act, the Rules
and Regulations, or any other federal or state law or regulation, common law or
otherwise, arising out of or based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in (a) Section 4 of this
Agreement, (b) the Offering Materials (except those written statements relating
to the Placement Agent given by the Placement Agent for inclusion therein), (c)
any application or other document or written communication executed by the
Company or based upon written information furnished by the Company filed in any
jurisdiction in order to qualify the Common Stock under the securities laws
thereof, or any state securities commission or agency; (ii) the omission or
alleged omission from documents described in clauses (a), (b) or (c) above of a
material fact required to be stated therein or necessary to make the statements
therein not misleading; or (iii) the breach of any representation, warranty,
covenant or agreement made by the Company in this Agreement. The Company further
agrees that upon demand by an indemnified person, at any time or from time to
time, it will promptly reimburse such indemnified person for any loss, claim,
damage, liability, cost or expense actually and reasonably paid by the
indemnified person as to which the Company has indemnified such person pursuant
hereto. Notwithstanding the foregoing provisions of this Paragraph 7(A), any
such payment or reimbursement by the Company of fees, expenses or disbursements
incurred by an indemnified person in any proceeding in which a final judgment by
a court of competent jurisdiction (after all appeals or the expiration of time
to appeal) is entered against the Placement Agent or such indemnified person
based upon specific finding of fact that the Placement Agent or such indemnified
person's gross negligence or willful misfeasance will be promptly repaid to the
Company.

                  B. The Placement Agent hereby agrees that it will indemnify
and hold the Company and each officer, director, shareholder, employee or
representative of the Company, and each person controlling, controlled by or
under common control with the Company within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act or the Rules and Regulations, harmless
from and against any and all loss, claim, damage, liability, cost or expense
whatsoever (including, but not limited to, any and all reasonable legal fees and
other expenses and disbursements incurred in connection with investigating,
preparing to defend or defending any action, suit or proceeding, including any
inquiry or investigation, commenced or threatened, or any claim whatsoever or in
appearing or preparing for appearance as a witness in any action, suit or
proceeding, including any inquiry, investigation or pretrial proceeding such as
a deposition) to which the Company or such indemnified person of the Company may
become subject under the 1933 Act, the 1934 Act, the Rules and Regulations, or
any other federal or state law or regulation, common law or otherwise, arising
out of or based upon (i) (i) the material breach of any representation,
warranty, covenant or agreement made by the Placement Agent in this Agreement
(ii) any false or misleading information provided to the Company in writing by
one of the Placement Agent's indemnified persons specifically for inclusion in
the Offering Materials or.

                  C. The Investor hereby agrees that it will indemnify and hold
the Placement Agent and each officer, director, shareholder, employee or
representative of the Placement Agent, and each person controlling, controlled
by or under common control with the Placement Agent within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act or the Rules and
Regulations, harmless from and against any and all loss, claim, damage,
liability, cost

                                       9
<PAGE>

or expense whatsoever (including, but not limited to, any and all reasonable
legal fees and other expenses and disbursements incurred in connection with
investigating, preparing to defend or defending any action, suit or proceeding,
including any inquiry or investigation, commenced or threatened, or any claim
whatsoever or in appearing or preparing for appearance as a witness in any
action, suit or proceeding, including any inquiry, investigation or pretrial
proceeding such as a deposition) to which the Placement Agent or such
indemnified person of the Placement Agent may become subject under the 1933 Act,
the 1934 Act, the Rules and Regulations, or any other federal or state law or
regulation, common law or otherwise, arising out of or based upon (i) the
conduct of the Investor or its officers, employees or representatives in its
acting as the Investor for the Offering or (ii) the material breach of any
representation, warranty, covenant or agreement made by the Investor in the
Offering Materials (iii) any false or misleading information provided to the
Placement Agent by one of the Investor's indemnified persons or.

                  D. The Placement Agent hereby agrees that it will indemnify
and hold the Investor and each officer, director, shareholder, employee or
representative of the Investor, and each person controlling, controlled by or
under common control with the Investor within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act or the Rules and Regulations, harmless
from and against any and all loss, claim, damage, liability, cost or expense
whatsoever (including, but not limited to, any and all reasonable legal fees and
other expenses and disbursements incurred in connection with investigating,
preparing to defend or defending any action, suit or proceeding, including any
inquiry or investigation, commenced or threatened, or any claim whatsoever or in
appearing or preparing for appearance as a witness in any action, suit or
proceeding, including any inquiry, investigation or pretrial proceeding such as
a deposition) to which the Investor or such indemnified person of the Investor
may become subject under the 1933 Act, the 1934 Act, the Rules and Regulations,
or any other federal or state law or regulation, common law or otherwise,
arising out of or based upon (i) the material breach of any representation,
warranty, covenant or agreement made by the Placement Agent in this Agreement or
..

                  E. Promptly after receipt by an indemnified party of notice of
commencement of any action covered by Section 7(A), (B), (C) or (D), the party
to be indemnified shall, within five (5) business days, notify the indemnifying
party of the commencement thereof; the omission by one (1) indemnified party to
so notify the indemnifying party shall not relieve the indemnifying party of its
obligation to indemnify any other indemnified party that has given such notice
and shall not relieve the indemnifying party of any liability outside of this
indemnification if not materially prejudiced thereby. In the event that any
action is brought against the indemnified party, the indemnifying party will be
entitled to participate therein and, to the extent it may desire, to assume and
control the defense thereof with counsel chosen by it which is reasonably
acceptable to the indemnified party. 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 such
Section 7(A), (B), (C), or (D) for any legal or other expenses subsequently
incurred by such indemnified party in connection with the defense thereof, but
the indemnified party may, at its own expense, participate in such defense by
counsel chosen by it, without, however, impairing the indemnifying party's
control of the defense. Subject to the proviso of this sentence and
notwithstanding any other statement to the contrary contained herein, the
indemnified party or parties shall have the right to choose its or their own
counsel and control the defense of any

                                       10
<PAGE>

action, all at the expense of the indemnifying party if, (i) the employment of
such counsel shall have been authorized in writing by the indemnifying party in
connection with the defense of such action at the expense of the indemnifying
party, or (ii) the indemnifying party shall not have employed counsel reasonably
satisfactory to such indemnified party to have charge of the defense of such
action within a reasonable time after notice of commencement of the action, or
(iii) such indemnified party or parties shall have reasonably concluded that
there may be defenses available to it or them which are different from or
additional to those available to one or all of the indemnifying parties (in
which case the indemnifying parties shall not have the right to direct the
defense of such action on behalf of the indemnified party or parties), in any of
which events such fees and expenses of one additional counsel shall be borne by
the indemnifying party; provided, however, that the indemnifying party shall
not, in connection with any one action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstance, be liable for the reasonable fees and expenses of
more than one separate firm of attorneys at any time for all such indemnified
parties. No settlement of any action or proceeding against an indemnified party
shall be made without the consent of the indemnifying party.

                  F. In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in Section 7(A) or 7(B)
is due in accordance with its terms but is for any reason held by a court to be
unavailable on grounds of policy or otherwise, the Company and the Placement
Agent shall contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with the
investigation or defense of same) which the other may incur in such proportion
so that the Placement Agent shall be responsible for such percent of the
aggregate of such losses, claims, damages and liabilities as shall equal the
percentage of the gross proceeds paid to the Placement Agent and the Company
shall be responsible for the balance; provided, however, that no person guilty
of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933
Act shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 7(F), any person
controlling, controlled by or under common control with the Placement Agent, or
any partner, director, officer, employee, representative or any agent of any
thereof, shall have the same rights to contribution as the Placement Agent and
each person controlling, controlled by or under common control with the Company
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act
and each officer of the Company and each director of the Company shall have the
same rights to contribution as the Company. Any party entitled to contribution
will, promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against the other party under this Section 7(D), notify such party from
whom contribution may be sought, but the omission to so notify such party shall
not relieve the party from whom contribution may be sought from any obligation
they may have hereunder or otherwise if the party from whom contribution may be
sought is not materially prejudiced thereby. The indemnity and contribution
agreements contained in this Section 7 shall remain operative and in full force
and effect regardless of any investigation made by or on behalf of any
indemnified person or any termination of this Agreement.
