        THIS PURCHASE AGREEMENT (this "Agreement") is made as of the 13th day of February, 2004, by and between Pioneer

San Antonio, Texas, 78217, and the purchaser whose name and address are set forth on the signature page hereof (the "Purchaser"). 

        IN
CONSIDERATION of the mutual covenants contained in this Agreement, the Company and the Purchaser agree as follows: 

        SECTION
1.    Authorization of Sale of the Shares.    Subject to the terms and conditions of this Agreement, the
Company has authorized the issuance and sale of 4,400,000 shares (the "Shares") of common stock, par value $0.10 per share (the

        SECTION

in Appendix I attached hereto. 

        The
Company proposes to enter into the same form of purchase agreement with certain other investors (the "Other Purchasers") and expects
to complete sales of the Shares to them. The Purchaser and the Other Purchasers are hereinafter sometimes collectively referred to as the "Purchasers",
and this Agreement and the agreements executed by the Other Purchasers are hereinafter sometimes collectively referred to as the "Agreements". The term
"Placement Agents" shall mean Jefferies & Company, Inc. and Raymond James & Associates, Inc. 

        SECTION
3.    Delivery of the Shares at the Closing.    The completion of the purchase and sale of the Shares (the
"Closing") shall occur at the offices of Baker Botts L.L.P., 910 Louisiana, Houston, Texas 77002 as soon as practicable and as agreed to by the parties
hereto, within three business days following the execution of the Agreements, or on such later date or at such different location as the parties shall agree upon in writing, but not prior to the date
that the conditions for Closing set forth below have been satisfied or waived by the appropriate party (the "Closing Date"). 

        As
soon as practicable after the Closing, the Company shall cause to be delivered to the Purchaser one or more stock certificates registered in the name of the Purchaser, or, if so

were sold in reliance upon the exemption from registration under the Securities Act of 1933, as amended (the "Securities Act"), provided by
Section 4(2) thereof and Rule 506 promulgated thereunder. The name(s) in which the stock certificate(s) are to be registered are set forth in the Stock Certificate Questionnaire attached

Company. 

        SECTION
4.    Representations, Warranties and Covenants of the Company.    The Company hereby represents and warrants
to, and covenants with, the Purchaser as follows: 

        4.1    Organization and Qualification.    The Company is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Texas and the Company is qualified to do business as a foreign corporation in each jurisdiction in which such qualification is required, except where failure to
so qualify would not reasonably be expected to have a Material Adverse Effect (as defined herein). The subsidiaries of the Company are Pioneer Drilling Services, Ltd., a Texas limited
partnership, PDC Management Company, a Texas corporation, and PDC Investment Corporation, a Delaware corporation (each a "Subsidiary" and collectively,
the "Subsidiaries"). Each Subsidiary is a direct or indirect wholly-owned subsidiary of the Company. Each Subsidiary is duly organized, validly existing
and in good standing under the laws of its jurisdiction of incorporation or formation and is qualified to do business as a foreign entity in each jurisdiction in which such qualification is required,
except where failure to so qualify would not reasonably be expected to have a Material Adverse Effect. For purposes of this Agreement, the term "Material Adverse
Effect" shall mean a material adverse effect upon the business, condition (financial or otherwise), properties or results of operations of the Company and its Subsidiaries,
taken as a whole. 

        4.2    Authorized Capital Stock.    Except as disclosed in or contemplated by the Confidential Private Placement
Memorandum, dated February 5, 2004, prepared by the Company, including Exhibits A through I thereto, supplements and amendments thereto (the "Private Placement

all the issued and outstanding shares of the Company's Common Stock have been duly authorized and validly issued, are fully paid and nonassessable, have been issued in compliance with all federal and
state securities laws, were not issued in violation of any preemptive rights or other rights to subscribe for or purchase securities, and conform in all material respects to the description thereof

any preemptive rights or other rights to subscribe for or to purchase, any securities or obligations convertible into, or any contracts or commitments to issue or sell, shares of its capital stock or
any such options, rights, convertible securities or obligations. The description of the Company's stock, stock bonus and other stock plans or arrangements and the options or other rights granted and
exercised thereunder set forth in the Private Placement Memorandum

accurately
and fairly presents all material information with respect to such plans, arrangements, options and rights. With respect to each Subsidiary, (i) all the issued and outstanding shares
of capital stock or other equity interest of the Subsidiary have been duly authorized and validly issued, are fully paid and, in the case of each Subsidiary that is a corporation, nonassessable, have
been issued in compliance with applicable federal and state securities laws, were not issued in violation of or subject to any preemptive rights or other rights to subscribe for or purchase
securities, and (ii) there are no outstanding options to purchase, or any preemptive rights or other rights to subscribe for or to purchase, any securities or obligations convertible into, or

and paid for in the manner set forth in this Agreement, will be duly authorized, validly issued, fully paid and nonassessable and free and clear of all pledges, liens, restrictions and encumbrances
(other than restrictions on transfer under state and/or federal securities laws), and will conform in all material respects to the description thereof set forth in the Private Placement Memorandum. No
preemptive rights or other rights to subscribe for or purchase exist with respect to the issuance and sale of the Shares by the Company pursuant to this Agreement, except for such preemptive rights as
have been waived in writing. True and accurate copies of such waivers have been provided to the Placement Agents and their counsel on or prior to the date of this Agreement. No stockholder of the
Company has any right (which has not been waived or has not expired by reason of lapse of time following notification of the Company's intent to file the registration statement to be filed by it
pursuant to Section 7.1 (the "Registration Statement")) to require the Company to register the sale of any shares owned by such stockholder under
the Securities Act in the Registration Statement. No further approval or authority of the stockholders or the Board of Directors of the Company will be required for the issuance and sale of the Shares
to be sold by the Company as contemplated herein. 

        4.4    Due Execution, Delivery and Performance of this Agreement.    The Company has full legal right, corporate power
and authority to enter into this Agreement and perform the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by the Company. The execution, delivery and
performance of this Agreement by the Company and the consummation of the transactions herein contemplated will not violate any provision of the articles of incorporation, bylaws or equivalent
organizational documents, as applicable, of the Company or any of its Subsidiaries and will not result in the creation of any lien, charge, security interest or encumbrance upon any assets of the
Company or any of its Subsidiaries pursuant to the terms or provisions thereof, and will not conflict with, result in the breach or violation of, or constitute, either by itself or upon notice or the
passage of time or both, a default under (i) any agreement, lease, franchise, license, permit or other instrument to which the Company or any of its Subsidiaries is a party or by which the
Company or any of its Subsidiaries or any of their respective properties may be bound or affected and in each case which would have a Material Adverse Effect; or (ii) to the Company's
knowledge, any statute or any judgment, decree, order, rule or regulation of any court or any regulatory body, administrative agency or other governmental body applicable to the Company or any of its
Subsidiaries or any of their respective properties where such conflict, breach, violation or default is reasonably expected to result in a Material Adverse Effect. No consent, approval, authorization
or other order of any court, regulatory body, administrative agency or other governmental body is required for the execution and delivery of this Agreement or the consummation of the transactions
contemplated by this 

3

 

Agreement,
except for compliance with the blue sky laws and federal securities laws applicable to the offering of the Shares. Upon the execution and delivery of this Agreement, and assuming the valid
execution thereof by the Purchaser, this Agreement will constitute a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as enforceability
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' and contracting parties' rights generally and except as enforceability may be
subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and except as the indemnification agreements of the Company in
Section 7.3 hereof may be limited by federal or state securities laws or the public policy underlying such laws.

regulations promulgated thereunder (the "Rules and Regulations"). 

        4.6    No Defaults.    Neither the Company nor any of its Subsidiaries is in violation or default of any provision of
its articles of incorporation, bylaws or equivalent organizational documents, or in breach of or default with respect to any provision of any agreement, judgment, decree, order, lease, franchise,
license, permit or other instrument to which it is a party or by which it or any of its properties are bound which would reasonably be expected to have a Material Adverse Effect and there does not
exist any state of facts which, with notice or lapse of time or both, would constitute an event of default on the part of the Company or any of its Subsidiaries as defined in such documents and which
would reasonably be expected to have a Material Adverse Effect.

or governmental actions, suits or proceedings pending and (ii) to the Company's knowledge, there are no inquiries or investigations, nor are there any legal or governmental actions, suits, or
proceedings threatened to which the Company or any of its Subsidiaries is or may be a party or of which property owned or leased by the Company or any of its Subsidiaries is or may be the subject, or

        (c)   For
the benefit of the Company, the Purchaser previously agreed orally with the Placement Agents to keep confidential all information concerning this private placement.
The Purchaser understands that the information contained in the Private Placement Memorandum is strictly confidential and proprietary to the Company and has been prepared from the Company's publicly

Purchaser has full cognizance of and understands all the risk factors set forth under the caption "Risk Factors" in the Private Placement Memorandum. The Purchaser understands that the market price of
the Common Stock has been volatile and that no representation is being made as to the future value of the Common Stock. The Purchaser has the knowledge and experience in financial and business matters
as to be capable of evaluating the merits and risks of an investment in the Shares and has the ability to bear the economic risks of an investment in the Shares. 

        (e)   The
Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed upon or made any recommendation or
endorsement of the Shares. 

        (f)    Until
the conditions set forth in Section 7.4 of this Agreement are satisfied, the Purchaser understands that the Shares will bear a restrictive legend in
substantially the following form: 

"The
Shares evidenced by this certificate have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or the securities laws of any state or other jurisdiction. The
Shares may not be offered, sold, pledged or otherwise transferred except (1) pursuant to an exemption from registration under the Securities Act or (2) pursuant to an effective
registration statement under the Securities Act, in each case in accordance with all applicable securities laws of the states and other jurisdictions, and in the case of a transaction exempt from
registration, unless the Company has received an opinion of counsel reasonably satisfactory to it that such transaction does not require registration under the Securities Act and such other applicable
laws." 

9

 

        (g)   The
Purchaser's principal executive offices are in the jurisdiction set forth immediately below the Purchaser's name on the signature pages hereto. 

        (h)   The
Purchaser hereby covenants with the Company not to make any sale of the Shares under the Registration Statement without complying with the provisions of this
Agreement and without effectively causing the prospectus delivery requirement under the Securities Act to be satisfied, and the Purchaser acknowledges and agrees that such Shares are not transferable
on the books of the Company unless the certificate submitted to the transfer agent evidencing the Shares is accompanied by a separate Purchaser's Certificate of Subsequent Sale: (i) in the form
of Appendix II hereto, (ii) executed by an officer of, or other authorized person designated by, the Purchaser, and (iii) to the
effect that (A) the Shares have been sold in accordance with the Registration Statement, the Securities Act and any applicable state securities or blue sky laws and (B) the requirement
of delivering a current prospectus has been satisfied. The Purchaser will notify the Company promptly after the sale of all of its Shares. The Purchaser acknowledges that there may occasionally be
times when the Company must suspend the
use of the Prospectus forming a part of the Registration Statement (a "Suspension") until such time as an amendment to the Registration Statement has
been filed by the Company and declared effective by the Commission, or until such time as the Company has filed an appropriate report with the Commission pursuant to the Exchange Act. The Purchaser
hereby covenants that it will not sell any Shares pursuant to said Prospectus during the period commencing at the time at which the Company gives the Purchaser written notice of the Suspension of the
use of said Prospectus and ending at the time the Company gives the Purchaser written notice that the Purchaser may thereafter effect sales pursuant to said Prospectus. Notwithstanding the foregoing,
the Company agrees that no Suspension shall be for a period of longer than 90 consecutive days, and all Suspensions in any 365-day period shall not total more than 120 days. 

        (i)    The
Purchaser further represents and warrants to, and covenants with, the Company that (i) the Purchaser has full right, power, authority and capacity to enter
into this Agreement and to consummate the transactions contemplated hereby and has taken all necessary action to authorize the execution, delivery and performance of this Agreement, (ii) the
making and performance of this Agreement by the Purchaser and the consummation of the transactions herein contemplated will not violate any provision of the organizational documents of the Purchaser
or conflict with, result in the breach or violation of, or constitute, either by itself or upon notice or the passage of time or both, a default under any material agreement, mortgage, deed of trust,
lease, franchise, license, indenture, permit or other instrument to which the Purchaser is a party, or any statute or any authorization, judgment, decree, order, rule or regulation of any court or any
regulatory body, administrative agency or other governmental body applicable to the Purchaser, (iii) no consent, approval, authorization or other order of any court, regulatory body,
administrative agency or other governmental body is required on the part of the Purchaser for the execution and delivery of this Agreement or the consummation of the transactions contemplated by this
Agreement, (iv) upon the execution and delivery of this Agreement, this Agreement shall constitute a legal, valid and binding obligation of the Purchaser, enforceable in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' and contracting parties' rights generally and
except as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and except to the extent
enforcement of the indemnification provisions, set forth in Section 7.3 of this Agreement, may be limited by federal or state securities laws or the public policy underlying such laws, and
(v) there is not in effect any order enjoining or restraining the Purchaser from entering into or engaging in any of the transactions contemplated by this Agreement. 

10

 

        SECTION
6.    Survival of Representations, Warranties and Agreements.    Notwithstanding any investigation made by any
party to this Agreement or by the Placement Agents, all covenants, agreements, representations and warranties made by the Company and the Purchaser herein and in the certificates for the Shares
delivered pursuant hereto shall survive the execution of this Agreement, the delivery to the Purchaser of the Shares being purchased and the payment therefor for a period of three years, whereupon
such covenants, agreements, representations and warranties will terminate and expire. 

        SECTION
7.    Registration of the Shares; Compliance with the Securities Act.    

        7.1    Registration Procedures and Expenses.    The Company shall: 

        (a)   as
soon as reasonably practicable, but in no event later than ten (10) business days following the Closing Date, prepare and file with the Commission the
Registration Statement on Form S-3 relating to the sale of the Shares by the Purchaser and the Other Purchasers from time to time on the American Stock Exchange or the facilities of
any national securities exchange on which the Common Stock is then traded or in privately-negotiated transactions; 

        (b)   use
its commercially reasonable efforts, subject to receipt of necessary information from the Purchasers, to cause the Registration Statement to be declared effective
under the Securities Act within 60 days after the Closing Date if the Registration Statement is not reviewed by the Commission and within 90 days after the Closing Date if the
Registration Statement is reviewed by the Commission (each such date, the "Required Effective Date"); 

        (c)   use
commercially reasonable efforts to prepare and file with the Commission such amendments, including post-effective amendments, and supplements to the
Registration Statement and the Prospectus used in connection therewith as may be necessary to keep the Registration Statement effective as to the Shares until the earliest of (i) two years
after the effective date of the Registration Statement, or (ii) such time as the Shares become eligible for resale by non-affiliates pursuant to Rule 144(k) under the
Securities Act; 

        (d)   furnish
to the Purchaser with respect to the Shares registered under the Registration Statement (and to each underwriter, if any, of such Shares) such number of copies
of prospectuses and such other documents as the Purchaser may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Shares by the Purchaser; 

        (e)   file
documents required of the Company for normal Blue Sky clearance in states specified in writing by the Purchaser; provided, however, that the Company shall not be
required to qualify to do business or consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented; 

        (f)    bear
all expenses in connection with the procedures of this Section 7.1 and the registration of the Shares pursuant to the Registration Statement, other than fees
and expenses, if any, of counsel or other advisers to the Purchaser or the Other Purchasers or underwriting discounts, brokerage fees and commissions incurred by the Purchaser or the Other Purchasers,
if any; 

        (g)   file a
Form D with respect to the Shares as required under Regulation D and to provide a copy thereof to the Purchaser promptly after filing; 

        (h)   issue
a press release describing the transactions contemplated by this Agreement on the Closing Date; and 

        (i)    make
available, while the Registration Statement is effective and available for resale, one or more officers of the Company for questions regarding the ability of the
Purchasers to use the Registration Statement or Prospectus; provided however, that such information may not include material, non-public information. 

11

 

        The
Company understands that the Purchaser disclaims being an underwriter, but the Purchaser being deemed an underwriter shall not relieve the Company of any obligations it has
hereunder. A draft of the proposed form of the Registration Statement is included with the Private Placement Memorandum and a questionnaire related thereto to be completed by the Purchaser is attached
hereto as Appendix I. 

        7.2    Transfer of Shares After Registration.    The Purchaser agrees that it will not effect any disposition of the
Shares or its right to purchase the Shares that would constitute a sale within the meaning of the Securities Act or any applicable state securities laws, except as contemplated in the Registration
Statement or as otherwise permitted by law, and that it will promptly notify the Company of any changes in the information set forth in the Registration Statement regarding the Purchaser or its plan
of distribution. 

        7.3    Indemnification.    

        (a)   For
purposes of this Section 7.3, (i) the term "Purchaser/Affiliate" shall mean the officers, directors,
agents and employees of the Purchaser, each person who controls the Purchaser (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers,
directors, agents and employees of each such controlling person; (ii) the term "Company/Affiliate" shall mean the officers, directors, agents and
employees of the Company, each person who controls the Company (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors,
agents and employees of each such controlling person; and (iii) the term "Registration Statement" shall include any preliminary prospectus, final
prospectus, exhibit, supplement or amendment included in or relating to, and any document incorporated by reference in, the Registration Statement referred to in Section 7.1. 

        (b)   The
Company agrees to indemnify and hold harmless each Purchaser and each Purchaser/Affiliate against any losses, claims, damages, liabilities or expenses, joint or
several, to which such Purchaser or Purchaser/Affiliate may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or
otherwise (including in settlement of any litigation, if such settlement is effected with the prior written consent of the Company), insofar as such losses, claims, damages, liabilities or expenses
(or actions in respect thereof as contemplated below) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement,
including the Prospectus, financial statements and schedules, and all other documents filed as a part thereof, as amended at the time of effectiveness of the Registration Statement, including any
information deemed to be a part thereof as of the time of effectiveness pursuant to paragraph (b) of Rule 430A, or pursuant to Rule 434, of the Rules and Regulations, or the
Prospectus, in the form first filed with the Commission pursuant to Rule 424(b) of the Regulations, or filed as part of the Registration Statement at the time of effectiveness if no
Rule 424(b) filing is required, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state in any of them a material fact required to be
stated therein or necessary to make the statements in any of them, in light of the circumstances under which they were made, not misleading, or arise out of or are based in whole or in part on any
inaccuracy in the representations or warranties of the Company contained in this Agreement, or any failure of the Company to perform its obligations hereunder or under law, and will promptly reimburse
each such Purchaser and each such Purchaser/Affiliate for any legal and other expenses as such expenses are reasonably incurred by such Purchaser or such Purchaser/Affiliate in connection with
investigating, defending or preparing to defend, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company will not be liable 

12

 

in
any such case to the extent, but only to the extent, that any such loss, claim, damage, liability or expense arises out of or is based upon (i) an untrue statement or alleged untrue
statement or omission or alleged omission made in the Registration Statement, 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 any Purchaser expressly for use therein, or (ii) the failure of any Purchaser to comply with the covenants and agreements contained in Sections 5 or
7.2, or (iii) the inaccuracy of any representation or warranty made by any Purchaser in or pursuant to any of the Agreements or (iv) any statement or omission in any Prospectus that is
corrected in any subsequent Prospectus that was delivered to the Purchaser prior to the pertinent sale or sales by the Purchaser. 

        (c)   Each
Purchaser will severally indemnify and hold harmless the Company and each Company/Affiliate against any losses, claims, damages, liabilities or expenses to which
the Company and each Company/Affiliate may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise
(including in settlement of any litigation, if such settlement is effected with the written consent of such Purchaser) insofar as such losses, claims, damages, liabilities or expenses (or actions in
respect thereof as contemplated below) arise out of or are based upon (i) any failure to comply with the covenants and agreements contained in Sections 5 or 7.2 hereof, or (ii) the
inaccuracy of any representation or warranty made by such Purchaser herein, or (iii) any untrue or alleged untrue statement of any 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 required to be stated
therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged
omission was made in the Registration Statement, 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 any Purchaser expressly for use therein, and will reimburse the Company and each Company/Affiliate for any legal and other expense reasonably incurred by the Company and each
Company/Affiliate in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Purchaser's obligation to indemnify
shall be limited to the net amount of the proceeds received by the Purchaser from the sale of the Common Stock pursuant to the Registration Statement. 

        (d)   Promptly
after receipt by an indemnified party under this Section 7.3 of notice of the threat or commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against an indemnifying party under this Section 7.3, promptly notify the indemnifying party in writing thereof; but the omission so to notify the
indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained in this Section 7.3 to
the extent it is not prejudiced as a result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an
indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the
defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded, based on an opinion of counsel reasonably satisfactory to the indemnifying party, that there may be a conflict of interest between the
positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which
are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to
otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon 

13

 

receipt
of notice from the indemnifying party to such indemnified party of its election to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party
will not be liable to such indemnified party under this Section 7.3 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless
(i) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood,
however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, reasonably satisfactory to such indemnifying party, representing all of the indemnified
parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. In no event shall any
indemnifying party be liable in respect of any amounts paid in settlement of any action unless the indemnifying party shall have approved in writing the terms of such settlement; provided that such
consent shall not be unreasonably withheld. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in
respect of which any indemnified party is or could have been a party and indemnification could have been sought hereunder by such indemnified party from all liability on claims that are the subject
matter of such proceeding, unless the terms of such settlement include a complete release of such indemnified party with respect to the underlying claim or claims. 

        (e)   If
the indemnification provided for in this Section 7.3 is required by its terms but is for any reason held to be unavailable to or otherwise insufficient to hold
harmless an indemnified party under paragraphs (b), (c) or (d) of this Section 7.3 in respect to any losses, claims, damages, liabilities or expenses referred to herein, then each
applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of any losses, claims, damages, liabilities or expenses referred to herein
(i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Purchaser from the private placement of Common Stock hereunder or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i)
above, but also the relative fault of the Company and the Purchaser in connection with the statements or omissions or inaccuracies in the representations and warranties in this Agreement and/or the
Registration Statement which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The respective relative benefits received by the
Company on the one hand and each Purchaser on the other shall be deemed to be in the same proportion as the amount paid by such Purchaser to the Company pursuant to this Agreement for the Shares
purchased by such Purchaser that were sold pursuant to the Registration Statement bears to the difference (the "Difference") between the amount such
Purchaser paid for the Shares that were sold pursuant to the Registration Statement and the amount received by such Purchaser from such sale. The relative fault of the Company, on the one hand, and
each Purchaser on the other shall be determined by reference to, among other things, whether the untrue or alleged statement of a material fact or the omission or alleged omission to state a material
fact or the inaccurate or the alleged inaccurate representation and/or warranty relates to information supplied by the Company or by such Purchaser and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to
above shall be deemed to include, subject to the limitations set forth in paragraph (d) of this Section 7.3, any legal or other fees or expenses reasonably incurred by such party in
connection with investigating or defending any action or claim. The provisions set forth in paragraph (d) of this Section 7.3 with respect to the notice of the threat or commencement of
any threat or action shall apply if a claim for contribution is to be made under this paragraph (e); provided, however, that no additional notice shall be required with respect to 

14

 

any
threat or action for which notice has been given under paragraph (d) for purposes of indemnification. The Company and each Purchaser agree that it would not be just and equitable if
contributions pursuant to this Section 7.3 were determined solely by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations
referred to in this paragraph. Notwithstanding the provisions of this Section 7.3, no Purchaser shall be required to contribute any amount in excess of the amount by which the Difference
exceeds the amount of any damages that such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contributions from any person who was not guilty of such fraudulent
misrepresentation. The Purchasers' obligations to contribute pursuant to this Section 7.3 are several and not joint. 

        7.4    Termination of Conditions and Obligations.    The restrictions imposed by Section 5 or this
Section 7 upon the transferability of the Shares shall cease and terminate as to any particular number of the Shares upon the passage of two years from the effective date of the Registration
Statement covering such Shares or at such time as an opinion of counsel satisfactory in form and substance to the Company shall have been rendered to the effect that such conditions are not necessary
in order to comply with the Securities Act. 

        7.5    Delay in Effectiveness of Registration Statement.    If (i) the Registration Statement filed hereunder
is not declared effective by the Commission by the Required Effective Date, for each month any of the Shares remain unregistered following the Required Effective Date, the Company shall issue to the
Purchaser additional shares of Common Stock in an amount equal to 1% of the total shares of Common Stock purchased by the Purchaser pursuant to Section 2 above, or (ii) the Purchaser
shall be prohibited from selling Shares under the Registration Statement as a result of a Suspension of more than 45 days or one or more Suspensions in any 365-day period exceeding
a total of 90 days, then for each month in which a Suspension is in effect that exceeds the maximum allowed period for a Suspension or Suspensions, the Company shall issue to the Purchaser
additional shares of Common Stock in an amount equal to 1% of the total shares of Common Stock purchased by the Purchaser pursuant to Section 2 above. Notwithstanding the foregoing:
(i) in no event shall the number of additional shares of Common Stock issued to the Purchaser pursuant to this Section 7.5 exceed 10% of the total shares of Common Stock purchased by the
Purchaser pursuant to Section 2 above; (ii) if as a result of the issuance of any such additional shares the Company would be required to seek shareholder approval pursuant to the rules,
regulations or other requirements of the American Stock Exchange or any other national securities exchange or quotation system on which the Common Stock is then traded or quoted, the Company may, in
lieu of issuing any such additional shares, pay to the Purchaser an amount in cash equal to the Applicable Percentage (as defined below) of the aggregate purchase price paid by the Purchaser pursuant
to Section 2 above; and (iii) in no event shall the Company be obligated to issue additional shares of Common Stock pursuant to this Section 7.5 to more than one Purchaser in
respect of the same Shares for the same period of time. Any issuance or payment pursuant to this Section 7.5 shall be made no later than the first business day of each calendar month next
succeeding each month in which such Suspension is in effect. For purposes of this Section 7.5, the term "Applicable Percentage" shall mean the
difference obtained by subtracting (i) the percentage that corresponds to the maximum amount of shares of Common Stock that the Company may issue in a transaction or a series of related
transactions without shareholder approval pursuant to the rules, regulations or other requirements of the American Stock Exchange or any other national securities exchange or quotation system on which
the Common Stock is traded or quoted as of the applicable date to calculate the Applicable Percentage, from (ii) the percentage that the Shares and all additional shares issued pursuant to this
Section 7.5 represent of the total outstanding shares of Common Stock as of the applicable date to calculate the Applicable Percentage. 

15

 

        SECTION
8.    Broker's Fee.    The Purchaser acknowledges that the Company intends to pay to the Placement Agents a
fee in respect of the sale of the Shares to the Purchaser. The Purchaser and the Company hereby agree that the Purchaser shall not be responsible for such fee and that the Company will indemnify and
hold harmless the Purchaser and each affiliate of the Purchaser against any losses, claims, damages, liabilities or expenses, joint or several, to which such Purchaser or affiliate of the Purchaser
may become subject with respect to such fee. Each of the parties hereto hereby represents that, on the basis of any actions and agreements by it, there are no other brokers or finders entitled to
compensation in connection with the sale of the Shares to the Purchaser. 

        SECTION
9.    Notices.    All notices required or permitted hereunder shall be in writing and shall be deemed
effectively given: (i) upon delivery to the party to be notified; (ii) when received by confirmed facsimile; or (iii) one (1) business day after deposit with a nationally
recognized overnight carrier, specifying next business day delivery, with written verification of receipt. All communications shall be sent to the Company and the Purchaser as follows or at such other
