REPORTS OF INDEPENDENT REGISTERED CHARTERED
ACCOUNTANTS

To the Board of Directors and Shareholders of TransGlobe
Energy Corporation:

We have audited the consolidated balance sheets of TransGlobe
Energy Corporation and subsidiaries (the Company) as at December 31, 2009 and
2008 and the consolidated statements of (loss) income and retained earnings,
comprehensive (loss) income and cash flows for the years then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with Canadian generally
accepted auditing standards and the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and
perform an audit to obtain reasonable assurance whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, these consolidated financial statements present
fairly, in all material respects, the financial position of TransGlobe Energy
Corporation and subsidiaries as atDecember 31, 2009 and 2008 and the
results of their operations and their cash flows for the years then ended in
accordance with Canadian generally accepted accounting principles.

We have also audited, in accordance with the standards of the
Public Company Accounting Oversight Board (United States), the Company's
internal control over financial reporting as of December 31, 2009, based onthe criteria established in Internal ControlIntegrated Framework issued by
the Committee of Sponsoring Organizations of the Treadway Commission and our
report dated March 9, 2010 expressed an unqualified opinion on the Companys
internal control over financial reporting.

Comments by Independent Registered Chartered Accountants on
Canada-United States of America Reporting Differences

The standards of the Public Company Accounting Oversight Board
(United States) require the addition of an explanatory paragraph (following the
opinion paragraph) when there are changes in accounting principles that have a
material effect on the comparability of the Companys financial statements, such
as the changes described in Notes 2 and 19 to the consolidated financial
statements. Although we conducted our audits in accordance with both Canadian
generally accepted auditing standards and the standards of the Public Company
Accounting Oversight Board (United States), our report to the Board of Directors
and Shareholders of TransGlobe Energy Corporation, dated March 9, 2010, is
expressed in accordance with Canadian reporting standards which do not require a
reference to such changes in accounting principles in the auditors report when
the changes are properly accounted for and adequately disclosed in the financial
statements.

Exhibit 99.4 Report of Independent Registered Chartered
Accountants continued

To the Board of Directors and Shareholders of TransGlobe
Energy Corporation:

We have audited the internal control over financial reporting
of TransGlobe Energy Corporation and subsidiaries (the Company)as of
December 31, 2009, based on the criteria established in Internal
ControlIntegrated Framework issued by the Committee of Sponsoring Organizations
of the Treadway Commission. The Company's management is responsible for
maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting,
included in the accompanying Managements Report on Internal Control Over
Financial Reporting. Our responsibility is to express an opinion on the
Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in
all material respects. Our audit included obtaining an understanding of internal
control over financial reporting, assessing the risk that a material weakness
exists, testing and evaluating the design and operating effectiveness of
internal control based on the assessed risk, and performing such other
procedures as we considered necessary in the circumstances. We believe that our
audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a
process designed by, or under the supervision of, the company's principal
executive and principal financial officers, or persons performing similar
functions, and effected by the company's board of directors, management, and
other personnel to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles. A
company's internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with
authorizations of management and directors of the company; and (3) provide
reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the company's assets that could have a
material effect on the financial statements.

Because of the inherent limitations of internal control over
financial reporting, including the possibility of collusion or improper
management override of controls, material misstatements due to error or fraud
may not be prevented or detected on a timely basis. Also, projections of any
evaluation of the effectiveness of the internal control over financial reporting
to future periods are subject to the risk that the controls may become
inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting as of December 31,
2009, based on the criteria established in Internal Control  Integrated
Frameworkissued by the Committee of Sponsoring Organizations of the
Treadway Commission.

We have also audited, in accordance with Canadian generally
accepted auditing standards and the standards of the Public Company Accounting
Oversight Board (United States), the consolidated financial statements as at and
for the year ended December 31, 2009 of the Company and our report dated March
9, 2010 expressed an unqualified opinion on those financial statements and
included a separate report titled Comments by Independent Registered Chartered
Accountants on Canada-United States of America Reporting Difference referring to
changes in accounting principles.
