          REGISTRATION RIGHTS AGREEMENT, dated as of March 31, 2005 (this
"Agreement"), between Union Drilling, Inc., a Delaware corporation (the
"Company"), and Richard Thornton ("Holder").

          This Agreement is being entered into in connection with the Stock
Purchase Agreement dated as of March 31, 2005 (the "Purchase Agreement"),
between the Company and Holder, providing for, among other things, the issuance
by the Company to Holder of an aggregate of 111,111 shares (the "Shares") of the
common stock, par value $0.01 per share (the "Common Stock"), of the Company, in
consideration for the payment by Holder to the Company of $1,999,998 ($18.00 per
share). For the purposes of this Agreement, the Shares shall be deemed to
include any shares of Common Stock issued with respect to the Shares by way of a
stock split, reverse stock split or combination, or stock dividend. It is a
condition precedent to the obligations of Holder to consummate the transactions
contemplated by the Purchase Agreement that the Company execute and deliver this
Agreement. Capitalized terms used herein but not otherwise defined shall have
the meanings given them in the Purchase Agreement.

          1. Registration Under Securities Act, etc.

          1.1 Piggy-Back Registration.

               (a) Right to Include Shares. If the Company at any time proposes
to file a registration statement to register shares of Common Stock under the
Securities Act (other than a registration (A) on Form S-8 or S-4 or any
successor or similar forms or (B) relating to Common Stock issuable upon
exercise of employee share options or in connection with any employee benefit or
similar plan of the Company), for sale by any of its shareholders, it will each
such time give prompt written notice (the "Company Notice") to Holder of its
intention to do so and of Holder's rights under this Section 1.1. Subject to
Section 1.1(a) below, upon the written request of Holder (which request shall
specify the amount of Shares intended to be disposed of by Holder) made as
promptly as practicable and in any event within 20 days after the receipt of any
such notice, the Company will use its best efforts to effect the registration
under the Securities Act of all Shares which the Company has been so requested
to register by Holder up to the Maximum Amount. As used herein, the term
"Maximum Amount" shall mean, at any time and from time to time, the product of
(i) a fraction, the numerator of which shall be the number of Shares Holder has
requested be included in the registration statement and the denominator of which
shall be the total number of shares of Common Stock all shareholders of the
Company have requested be included in the registration statement, multiplied by
(ii) the total number of shares of Common Stock held by shareholders of the
Company that the Company intends to include in such registration.

               (b) Company Right to Withdraw Registration. Notwithstanding
anything to the contrary set forth herein, (A) if the registration involves an
underwritten public offering, Holder must sell his Shares to the underwriters on
the same terms and conditions as apply to the Other Shareholders and (B) if, at
any time after giving written notice of its intention to register any Common
Stock pursuant to Section 1.1(a), the Company shall determine in its sole and
arbitrary discretion for any reason not to register, or to withdraw such
registration of, such Common Stock, the Company shall give written notice of
such determination to Holder and, thereupon, may withdraw or cease to pursue
such registration and shall be relieved of its obligation hereunder to register,
or maintain the registration of, any Shares in connection with such withdrawn or
otherwise terminated registration.


                                        1



               (c) Priority. If the Company in its sole discretion shall
determine that the total amount of Shares requested to be included in a
registration pursuant to Section 1.1(a) would have a material adverse effect on
such offering, then the Company shall include in such registration, first, all
securities proposed by the Company to be sold for its own account and second,
all securities being offered for the account of other persons or entities, pro
rata on the basis of the estimated gross proceeds from the sale thereof.

               (d) Expenses. The Company will pay all registration expenses in
connection with any registration effected pursuant to this Section 1.1, except
that Holder shall pay all brokerage and underwriting fees, discounts and
commissions with respect to the Shares offered for sale by Holder in such
registration and all fees and expenses of Holder's own counsel or advisors with
respect to such registration, if any.

          1.2 Registration Procedures. (a) Subject to Section 1.1(b), if and
whenever the Company is required to effect the registration of any Shares under
the Securities Act as provided in Section 1.1, the Company will, as
expeditiously as possible use its best efforts to:

               (i) furnish to Holder such number of conformed copies of such
          registration statement and of each such amendment and supplement
          thereto (in each case including all exhibits), such number of copies
          of the prospectus contained in such registration statement (including
          each preliminary prospectus and any summary prospectus) and any other
          prospectus filed under Rule 424 under the Securities Act, in
          conformity with the requirements of the Securities Act, as Holder may
          reasonably request; and

               (ii) notify Holder at any time when a prospectus relating to such
          registration statement is required to be delivered under the
          Securities Act, upon discovery that, or upon the happening of any
          event as a result of which, the prospectus included in such
          registration statement, as then in effect, includes an untrue
          statement of a material fact or omits to state any material fact
          required to be stated therein or necessary to make the statements
          therein not misleading, in the light of the circumstances under which
          they were made, and at the request of Holder promptly prepare and
          furnish to him a reasonable number of copies of a supplement to or an
          amendment of such prospectus as may be necessary so that, as
          thereafter delivered to the purchasers of such securities, such
          prospectus shall not include an untrue statement of a material fact or
          omit to state a material fact required to be stated therein or
          necessary to make the statements therein not misleading in the light
          of the circumstances under which they were made.

               (b) Notwithstanding the foregoing provisions of Section 1.2(a),
the Company may, during the registration period, suspend the use of the
prospectus included in the registration statement for an unlimited period of
time if, for any reason, the Company determines in its sole discretion that it
is in the best interests of the Company to suspend such use, and prior to or
contemporaneously with suspending such use, the Company provides Holder with
written notice of such suspension, which notice need not specify the reason for
such suspension. At the end of any such suspension period, the Company shall
provide Holder with written notice of the termination of such suspension.


                                       2



               (c) Holder agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in subdivision (ii)
of Section 1.2(a), Holder will forthwith discontinue Holder's disposition of
Shares pursuant to the registration statement relating to such Shares until
Holder's receipt of the copies of the supplemented or amended prospectus
contemplated by subdivision (ii) of Section 1.2(a) and, if so directed by the
Company, will deliver to the Company (at the Company's expense) all copies,
other than permanent file copies, then in Holder's possession of the prospectus
relating to such Shares current at the time of receipt of such notice.

               (d) Holder agrees that upon receipt of any notice from the
Company of a suspension of the use of the prospectus described in Section
1.2(b), or a withdrawal of the registration statement described in Section
1.2(b), or the issuance of a stop order described in Section 1.4, Holder shall
forthwith discontinue Holder's disposition of shares pursuant to such suspended
or withdrawn registration statement until Holder's receipt of written notice
from the Company that either such suspension has been terminated or such stop
order has been withdrawn.

          1.3 Underwritten Offerings. If the Company proposes to register any of
its securities under the Securities Act as contemplated by Section 1.1 and such
securities are to be distributed by or through one or more underwriters, at the
Company's request, Holder shall be a party to the underwriting agreement between
the Company and such underwriters. Holder shall not be required to make any
representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties or agreements regarding
Holder, Holder's Shares and Holder's intended method of distribution of the
Shares or any other representations required by applicable law.

          1.4 Stop Orders. The Company shall promptly notify the Holder of any
stop order issued or threatened by the Commission relating to a registration
statement registering any Shares.

          1.5 Indemnification.

               (a) Indemnification by the Company. The Company will, and hereby
does, indemnify and hold harmless Holder, in the case of any registration
statement filed pursuant to Section 1.1, against any losses, claims, damages or
liabilities to which Holder may become subject under the Securities Act or
otherwise, including, without limitation, the reasonable fees and expenses of
legal counsel, insofar as such losses, claims, damages or liabilities (or
actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon any untrue statement of any material fact
contained in any registration statement under which Shares were registered under
the Securities Act, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, or any
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein in light of the circumstances in which
they were made not misleading; provided, that the Company shall not be liable in
any such case to the extent that any such loss, claim, damage, liability (or
action or proceeding in respect thereof) or expense arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in such registration statement, any such preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement in reliance upon
and in conformity with information furnished to the Company by or on behalf of
Holder.


                                       3



               (b) Indemnification by Holder. As a condition to including any
Shares in any registration statement, the Company shall have received an
undertaking satisfactory to it from Holder, to indemnify and hold harmless (in
the same manner and to the same extent as set forth in subdivision (a) of this
Section 1.5) the Company, and each director of the Company, each officer of the
Company and each other person, if any, who participates as an underwriter in the
offering or sale of such securities and each other person who controls the
Company or any such underwriter within the meaning of the Securities Act, with
respect to any statement in or omission from such registration statement, any
preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto, if such statement or omission
was made in reliance upon and in conformity with information furnished to the
Company by Holder; provided, however, that the liability of Holder shall not in
any event to exceed the net proceeds received by Holder from the sale of Shares
covered by such registration statement.

               (c) Notices of Claims, etc. Promptly after receipt by an
indemnified party of notice of the commencement of any action or proceeding
involving a claim referred to in the preceding subdivisions of this Section 1.5,
such indemnified party will, if a claim in respect thereof is to be made against
an indemnifying party, give written notice to the latter of the commencement of
such action; provided, however, that the failure of any indemnified party to
give notice as provided herein shall not relieve the indemnifying party of its
obligations under the preceding subdivisions of this Section 1.5, except to the
extent that the indemnifying party is actually prejudiced by such failure to
give notice. In case any such action is brought against an indemnified party,
the indemnifying party shall be entitled to participate in and to assume the
defense thereof, to the extent that it may wish, and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party shall not be liable to such indemnified
party for any legal or other expenses subsequently incurred by the latter in
connection with the defense thereof. No indemnifying party shall be liable for
any settlement of any action or proceeding effected without its written consent.
No indemnifying party shall, without the consent of the indemnified party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such indemnified party of a release from all liability in respect to such
claim or litigation or which requires action other than the payment of money by
the indemnifying party.

          2. Holder's Obligations. The Holder's right to have Shares included in
a registration statement pursuant to the provisions of Section 1 above shall be
subject to the following further conditions:

               (a) Holder shall have promptly furnished to the Company in
writing any and all such information, agreements and documents regarding Holder
and any distribution of Shares proposed by him as the Company, the managing
underwriter(s) of any proposed issuance of securities by or on behalf of the
Company, if any, and its counsel may reasonably request; and

               (b) Holder shall have executed and delivered to the Company such
written undertakings as the Company and its counsel may reasonably require in
order to assure full compliance with applicable provisions of the Securities Act
and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), which
may include, without limitation, undertakings not to buy any securities of the
same class as the Shares or to solicit such purchases by others until Holder's
distribution of Shares is completed and otherwise to comply with the
Commission's anti-manipulation rules, and to inform any


                                        4



exchange upon which the Company's common stock may be traded and the managing

elect, in its sole discretion, to include any remaining unregistered Shares in
one or more subsequently filed registration statements registering securities of
