MANAGEMENTS REPORT ON INTERNAL CONTROL OVER FINANCIAL
REPORTING AND CHANGES THERETO

Management is responsible for establishing and maintaining
adequate internal control over financial reporting as defined in Rule 13a-15(f)
under the Securities Exchange Act of 1934, as amended (the Exchange
Act). Our internal control system is designed 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 in Canada and in the United States.

Management recognizes that effective internal control over
financial reporting may nonetheless not prevent or detect all possible
misstatements or frauds. Also, projections of any evaluation of effectiveness to
future periods are subject to the risk that controls may become inadequate
because of changes in conditions, or that the degree of compliance with policies
or procedures may deteriorate.

Pursuant to published guidance from the SEC Staff, management
has excluded from its assessment the internal control over financial reporting
at Dublin International Petroleum (Egypt) Limited and Drucker Petroleum Inc.,
which were acquired on September 25, 2007 and whose financial statements
constitute 55 percent and 35 percent of net and total assets, respectively, 8
percent of revenues, and 9 percent of net income of the Consolidated Audited
Annual Financial Statement amounts as of and for the fiscal year ended December
31, 2007. Subject to the foregoing, no change in the Registrants internal
control over financial reporting identified in connection with the evaluation
required by paragraph (d) of Exchange Act Rule 13a-15 occurred during the fiscal
year ended December 31, 2007 that has materially affected, or is reasonably
likely to materially affect, the Registrants internal control over financial
reporting.

Management has evaluated the effectiveness of the Registrant's
internal control over financial reporting as of fiscal year ended December 31,
2007 based on the framework in Internal Control  Integrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
Based on this evaluation, management concluded that, as of fiscal year ended
December 31, 2007, the Registrant maintained effective internal control over
financial reporting.

Deloitte & Touche LLP, the independent registered public
accounting firm that audited the Registrant's consolidated financial statements
as of fiscal year ended December 31, 2007, has expressed its opinion on the
effectiveness of the Registrants internal control over financial reporting as
of fiscal year ended December 31, 2007. A copy of Deloitte & Touche LLPs
attestation report on internal control over financial reporting is included
herein as Exhibit 99.4 of this Annual Report on Form 40-F.

ATTESTATION REPORT OF THE REGISTERED PUBLIC ACCOUNTING FIRM

For the Attestation report of the independent registered
chartered accountants for the fiscal year ended December 31, 2007, see Exhibit
99.4 of this Annual Report on Form 40-F.

NOTICES PURSUANT TO REGULATION BTR

None.

AUDIT COMMITTEE FINANCIAL EXPERT

The Registrants Board of Directors has determined that it has
at least one Audit Committee financial expert serving on its Audit Committee.
Fred J. Dyment has been determined by the Registrants Board of Directors to
meet the Audit Committee financial expert criteria prescribed by the
Securities and Exchange Commission and is independent, as that term is defined
by the AMEXs listing standards applicable to the Registrant. Fred J. Dyment is
a Chartered Accountant with over 30 years' experience in the oil and gas
industry. He was previously President and Chief Executive Officer of Maxx
Petroleum Company (2000-2001). Prior thereto he was Controller, Vice President
Finance and then President and Chief Executive Officer of Ranger Oil Limited
from 1978-2000. The SEC has indicated that the designation of Fred J. Dyment as
an Audit Committee financial expert does not make him an expert for any
purpose, impose any duties, obligations or liability on him that are greater
than those imposed on members of the Audit Committee and Board of Directors who
do not carry this designation, or affect the duties, obligations or liability of
any other member of the Audit Committee.

Annual Report on Form 40-F for fiscal year ended December 31, 2006. Shareholders
may obtain a copy upon request, addressed to The Secretary, TransGlobe Energy

website at http://www.trans-globe.com/s/CodeofConduct.asp. All amendments to the
Codes of Ethics and all waivers of the Codes of Ethics with respect to any of

FORWARD-LOOKING STATEMENTS

This Annual Report on Form 40-F may include certain statements
deemed to be forward-looking statements within the meaning of the U.S. Private
Securities Litigation Reform Act of 1995. Such statements relate to possible
future events. All statements other than statements of historical fact may be
forward-looking statements. Forward-looking statements are often, but not
always, identified by the use of words such as "seek", "anticipate", "plan",
"continue", "estimate", "expect", "may", "will", "project", "predict",
"potential", "targeting", "intend", "could", "might", "should", "believe" and
similar expressions. These statements involve known and unknown risks,
uncertainties and other factors that may cause actual results or events to
differ materially from those anticipated in such forward-looking statements.
Although the Registrant's forward-looking statements are based on the beliefs,
expectations, opinions and assumptions of the Registrant's management on the
date the statements are made, such statements are inherently uncertain and
provide no guarantee of future performance. Actual results may differ materially
from the Registrant's expectations as reflected in such forward-looking
statements as a result of various factors, many of which are beyond the control
of the Registrant. These factors include, but are not limited to, unforeseen
changes in the rate of production from the Registrant's oil and gas properties,
changes in the price of crude oil and natural gas, adverse technical factors
associated with exploration, development, production or transportation of the
Registrant's crude oil and natural gas reserves, changes or disruptions in the
political or fiscal regimes in the Registrant's areas of activity, changes in
tax, energy or other laws or regulations, changes in significant capital
expenditures, delays or disruptions in production due to shortages of skilled
manpower, equipment or materials, economic fluctuations, and other factors
beyond the Registrant's control.

In particular, this Annual Report on Form 40-F contains
forward-looking statements pertaining to the following:

5

---

- the quantity of reserves;
- oil and natural gas production levels;
- capital expenditure programs;
- projections of market prices and costs;
- supply and demand for oil and natural gas;
- expectations regarding the Company's ability to raise capital and to
  continually add to reserves through exploration, acquisitions and development;
  and
- treatment under government regulatory and taxation regimes.

The Registrant's actual results could differ materially from
those anticipated in these forward-looking statements as a result of the risk
factors set forth below and elsewhere in this Annual Report on Form 40-F:

- volatility in market prices for oil and natural gas;
- liabilities and risks inherent in oil and natural gas operations;
- uncertainties associated with estimating reserves;
- competition for, among other things, capital, acquisitions of reserves,
  undeveloped lands, equipment and skilled personnel;
- incorrect assessments of the value of acquisition; and
- geological, technical, drilling and processing problems.

The Registrant does not assume any obligation to update
forward-looking statements if circumstances or managements beliefs,
expectations or opinions should change, and investors should not attribute undue
certainty to, or place undue reliance on, any forward-looking statements. Please
consult the Registrant's public filings at
http://www.sedar.com/search/search_form_pc_en.htm and
http://www.sec.gov/edgar/searchedgar/companysearch.html for further, more
detailed information concerning these matters.
