REPORTS OF INDEPENDENT REGISTERED CHARTERED
ACCOUNTANTS

To the Board of Directors and Shareholders of TransGlobe Energy
Corporation

We have audited the accompanying consolidated financial
statements of TransGlobe Energy Corporation and subsidiaries, which comprise the
consolidated balance sheets as at December 31, 2010 and 2009, and the
consolidated statements of income (loss) and retained earnings, comprehensive
income (loss) and cash flows for each of the years then ended and the notes to
the consolidated financial statements.

Management's responsibility for the consolidated financial
statements

Management is responsible for the preparation and fair
presentation of these consolidated financial statements in accordance with
Canadian generally accepted accounting principles, and for such internal control
as management determines is necessary to enable the preparation of consolidated
financial statements that are free from material misstatement, whether due to
fraud or error.

Auditor's responsibility

Our responsibility is to express an opinion on these
consolidated 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 comply with ethical requirements and plan and
perform the audit to obtain reasonable assurance about whether the consolidated
financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit
evidence about the amounts and disclosures in the consolidated financial
statements. The procedures selected depend on the auditor's judgment, including
the assessment of the risks of material misstatement of the consolidated
financial statements, whether due to fraud or error. In making those risk
assessments, the auditor considers internal control relevant to the entity's
preparation and fair presentation of the consolidated financial statements in
order to design audit procedures that are appropriate in the circumstances. An
audit also includes evaluating the appropriateness of accounting policies used
and the reasonableness of accounting estimates made by management, as well as
evaluating the overall presentation of the consolidated financial
statements.

We believe that the audit evidence we have obtained in our
audits is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements present
fairly, in all material respects, the financial position of TransGlobe Energy
Corporation and subsidiaries as at December 31, 2010 and 2009, and the results
of its operations and its cash flows for each of the years then ended in
accordance with Canadian generally accepted accounting principles.

Other matters

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, 2010, based on the
criteria established in Internal ControlIntegrated Frameworkissued by
the Committee of Sponsoring Organizations of the Treadway Commission and our
report dated March 11, 2011 expressed an unqualified opinion on the Companys
internal control over financial reporting.

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, 2010, based on the criteria established in Internal ControlIntegrated
Frameworkissued 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, 2010, 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, 2010 of the Company and our report dated March
11, 2011 expressed an unqualified opinion on those financial statements.
