Slide 3 Accelerating Shareholder Returns and Value Growth Creating a world-class African-focused
E&P supporting sustainable shareholder returns and growth Declaration of dividends and terms of the buyback are subject to board approval. Equivalent dividend and buyback value per share calculated as US$ million value divided by the
enlarged share capital of ~108 million based on each company’s vested outstanding shares as of the date of the arrangement agreement. Aggregated figure prepared by management and not reviewed by competent person. Reserve figures of VAALCO and
TransGlobe are prepared under different standards and may not be directly comparable. VAALCO’s 1P reserves estimates have been prepared in accordance with U.S. Standards. VAALCO’s 2P reserves estimates represent proved plus probable estimates
are prepared in accordance with the definitions and guidelines set forth in the 2018 Petroleum Resources Management Systems approved by the Society of Petroleum Engineers using VAALCO management assumptions. TransGlobe’s 1P and 2P reserves
estimates were determined in accordance with standards set out in Canadian Oil and Gas Evaluation Handbook (“COGEH”) and the reserves definitions contained in NI 51-101 Standards of Disclosure for Oil and Gas Activities (“NI 51-101”). See

Eastern Desert production from the effective date of February 1, 2020 TransGlobe has recognized a receivable of US$67.5m at March 31, 2022, which represents the amount expected to be received from EGPC based on historical realized
prices Treatment in Business Combination Valuation The entire balance of US$67.5m has been captured in the business combination relative valuation analysis and implied exchange ratio, with TransGlobe’s shareholders receiving the full and

arrangement and for no other purpose. The information herein does not purport to be all-inclusive. Please refer to the arrangement agreement between TransGlobe and VAALCO dated July 13, 2022, plan of arrangement and other related transaction
documents for the full terms of the arrangement. Please also refer to the “Important Information About the Proposed Arrangement and Where to Find It” paragraph below. Neither VAALCO, TransGlobe nor any of their respective affiliates have any
obligation to update this Presentation. Although all information and opinions expressed in this Presentation were obtained from sources believed to be reliable and in good faith, no representation or warranty, express or implied, is made as to
its accuracy or completeness. This Presentation contains preliminary information only, is subject to change at any time and is not, and should not be assumed to be, complete or to constitute all the information necessary to adequately make an
informed decision regarding the proposed arrangement. Recipients of this Presentation should each make their own evaluation of VAALCO, TransGlobe and the proposed arrangement and of the relevance and adequacy of the information and should make
such other investigations as they deem necessary. Industry Data Information contained in this Presentation concerning the industry and markets in which either VAALCO or TransGlobe operates, including any general expectation, market position,
market opportunity and market size, is based on information from either management’s estimates and research, as well as from industry and general publications, and research, surveys and studies conducted by third parties. In some cases, VAALCO
and TransGlobe may not expressly refer to the sources from which this information is derived. Management estimates are derived from industry and general publications; research, surveys and studies conducted by third parties; VAALCO’s and
TransGlobe’s knowledge of the industry; and assumptions based on such information and knowledge, all of which VAALCO and TransGlobe believe to be reasonable. In addition, assumptions and estimates relating to VAALCO, TransGlobe and their
respective industries’ future performances are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause their future performances and actual market growth, opportunity and
size and the like to differ materially from the underlying assumptions and estimates. None of VAALCO, TransGlobe or their affiliates have independently verified any of the data from independent third party sources referred to in this
Presentation or ascertained the underlying assumptions relied upon by such sources. Trademarks and Trade Names VAALCO and TransGlobe own or have rights to various trademarks, service marks and trade names that they use in connection with the
operation of their respective businesses. This Presentation also contains trademarks, service marks and trade names of third parties, which are the property of their respective owners. The use or display of third parties’ trademarks, service
marks, trade names or products in this Presentation is not intended to, and does not imply, a relationship with VAALCO or TransGlobe, or an endorsement or sponsorship by or of VAALCO or TransGlobe. Solely for convenience, the trademarks,
service marks and trade names referred to in this Presentation may appear without the ®, TM or SM symbols, but such references are not intended to indicate, in any way, that VAALCO or TransGlobe will not assert, to the fullest extent under
applicable law, their rights or the right of the applicable licensor to these trademarks, service marks and trade names. Use of Projected Financial Information This Presentation contains projected financial information with respect to VAALCO
and TransGlobe, namely Adjusted EBITDA and expected production. Such projected financial information constitutes forward-looking information, and is for illustrative purposes only and should not be relied upon as necessarily being indicative of
future results. The assumptions and estimates underlying such projected financial information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could
cause actual results to differ materially from those contained in the prospective financial information. See “Forward-Looking Statements” paragraph below. Actual results may differ materially from the results contemplated by the projected
financial information contained in this Presentation, and the inclusion of such information in this Presentation should not be regarded as a representation by any person that the results reflected in such projections will be achieved. The
independent auditors and the independent registered public accounting firms of VAALCO and TransGlobe have not audited, reviewed, compiled or performed any procedures with respect to the projected financial information for the purpose of their
inclusion in this Presentation, and accordingly, none of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this Presentation. No undertaking is made to update any projected financial
information , except as required by applicable law. Use of Non-GAAP and Other Financial Measures Some of the financial information and data contained in this Presentation, such as Adjusted EBITDA and net cash, have not been prepared in
accordance with United States generally accepted accounting principles (“GAAP”) or with the International Standards of Financial Reporting (“IFRS”). VAALCO and TransGlobe believe these non-GAAP, non-IFRS, or other financial measures of
financial results, respectively, provide useful information to management and investors regarding certain financial and business trends relating to each of VAALCO’s and TransGlobe’s financial condition and results of operations. VAALCO and
TransGlobe believe that the use of these non-GAAP, non-IFRS, or other financial measures, respectively, provides an additional tool for investors to use in evaluating projected operating results and trends in and in comparing each of VAALCO’s
and TransGlobe’s financial measures with other similar companies, many of which present similar non-GAAP, non-IFRS, or other financial measures to investors. Each of VAALCO’s and TransGlobe’s management does not consider these non-GAAP,
non-IFRS, or other financial measures, respectively, in isolation or as an alternative to financial measures determined in accordance with GAAP or IFRS, as the case may be. The principal limitation of these financial measures is that they
exclude significant expenses and income that are required by GAAP or IFRS to be recorded in VAALCO’s and TransGlobe’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by
management about which expenses and income are excluded or included in determining these financial measures. In order to compensate for these limitations, Each of VAALCO’s and TransGlobe’s management presents non-GAAP financial or other
financial measures in connection with GAAP or IFRS results. Net Cash Net cash is a non-GAAP financial measure that does not have any standardized meaning under IFRS/US GAAP and therefore may not be comparable to similar measures presented by
other companies. TransGlobe considers net cash to be a key measure to assess TransGlobe’s liquidity position at a point in time. The most directly comparable GAAP measure for net cash is cash and cash equivalents. Net cash is equal to total
cash and cash equivalents less long-term debt. TransGlobe’s net cash position at March 31, 2022 of US$34 million was determined by taking the March 31, 2022 cash balance of US$37 million, less long-term debt of US$3 million at March 31, 2022.
VAALCO’s net cash position at March 31, 2022 of US$19 million was equal to the March 31, 2022 cash and equivalent balance.
Slide 37 Disclaimers (cont.) Caution to U.S. and Canadian Investors Regarding Management's Reserve
Estimates Aggregated reserves figures prepared by management and not reviewed by competent person as required by local requirements. Reserve estimates of VAALCO and TransGlobe are prepared under different standards and may not be directly
comparable in all relevant respects. References to reserves in this Presentation represent crude oil and natural gas reserves only and, in each case, prepared by VAALCO management and TransGlobe management. VAALCO’s 1P reserves, net of
royalties, were prepared in accordance with United States Financial Accounting Standards Board’s (“FASB”) ASC Topic 932 – Extractive Activities – Oil and Natural Gas under U.S. GAAP and subpart 1200 of Regulation S-K promulgated by the SEC (the
“U.S. Standards”). VAALCO’s proved reserves “1P” on a working interest basis prior to deduction of royalties and VAALCO’s proved plus probable “2P” reserves represent estimates prepared in accordance with the definitions and guidelines set
forth in the 2018 Petroleum Resources Management Systems approved by the Society of Petroleum Engineers as of December 31, 2021 using escalated crude oil price and cost assumptions made by VAALCO’s management. The U.S. Standards definitions of
proved and probable reserves are different from the definitions contained in the 2018 Petroleum Resources Management Systems approved by the Society of Petroleum Engineers as of December 31, 2021 and from Canadian National Instrument 51-101 –
Standards of Disclosure for Oil and Gas Activities (“NI 51-101”). As a result, VAALCO's 1P working interest and 2P reserves may not be comparable to U.S. Standards or Canadian standards. The U.S. Standards require United States oil and gas
reporting companies, in their filings with the SEC, to disclose only proved reserves after the deduction of royalties and production due to others but permits the optional disclosure of probable and possible reserves in accordance with SEC’s
definitions. VAALCO’s 2P reserves may differ from the U.S. Standards and Canadian standards definitions of proved and probable reserves. Management of VAALCO uses 1P working interest and 2P reserves as a measurement of operating performance
because it assists management in strategic planning, budgeting and economic evaluations and in comparing the operating performance of VAALCO to other companies. Management of VAALCO believes that the presentation of VAALCO's 1P working interest
and 2P reserves and of the combined reserves is useful to its international investors, particularly those that invest in companies trading on the LSE, in order to better compare such reserves information to other LSE-traded companies that
report similar measures. VAALCO also believes that this information enhances its investors’ and securities analysts’ understanding of its business. However, 1P working interest and 2P reserves should not be used as a substitute for proved
reserves calculated in accordance with the definitions prescribed by the SEC. In evaluating VAALCO’s business, investors should rely on VAALCO’s SEC proved reserves and consider 1P working interest and 2P reserves only
supplementally. Additionally, TransGlobe’s reserves were determined in accordance with the standards set out in the Canadian Oil and Gas Evaluation Handbook (the “COGEH”) and the reserves definitions contained in NI 51-101, as required for a
Canadian reporting issuer under Canadian securities laws, and the 1P and 2P reserves estimates of VAALCO were not. The forecast of prices, inflation and exchange rates utilized in the TransGlobe reserves information were computed using the
average of the forecasts of GLJ Ltd., McDaniel & Associates Consultants Ltd. and Sproule Associates Limited each dated January 1, 2022. None of VAALCO, TransGlobe, or either of their respective qualified independent reserves evaluators has
been involved in the preparation of the other company’s reserve estimates. Neither of VAALCO’s nor TransGlobe’s independent reserves evaluators have been involved with the preparation of the combined reserves information in this document. In
addition to being a reporting issuer in all provinces of Canada, TransGlobe is a registrant with the SEC but is permitted to present disclosure of its reserves information in accordance with the standards set out in COGEH and the reserves
definitions contained in NI 51-101. Estimates of reserves and future net revenue made in accordance with COGEH and NI 51-101 will differ from corresponding measures prepared in accordance with the U.S. Standards and those differences may be
material. COGEH and NI 51-101, for example, require disclosure of reserves and related future net revenue estimates based on forecast prices and costs, whereas the U.S. Standards require that reserves and related future net revenue be estimated
using average prices for the previous 12 months and that the standardized measure reflect discounted future net income taxes related to VAALCO’s operations. In addition, COGEH and NI 51-101 permit the presentation of reserves estimates on a
“company gross” basis, representing TransGlobe’s working interest share before deduction of royalties, whereas the U.S. Standards require the presentation of net reserve estimates after the deduction of royalties and similar payments. There are
also differences in the technical reserves estimation standards applicable under NI 51-101 and, pursuant thereto, the COGEH, and those applicable under the U.S. Standards. NI 51-101 requires that proved undeveloped reserves be reviewed annually
for retention or reclassification if development has not proceeded as previously planned, while the U.S. Standards specify a five-year limit after initial booking for the development of proved undeveloped reserves. Finally, the SEC prohibits
disclosure of oil and gas resources in SEC filings, including contingent resources, whereas Canadian securities regulatory authorities allow disclosure of oil and gas resources. Resources are different than, and should not be construed as,
reserves. The foregoing is not an exhaustive summary of Canadian, U.S. or U.K. reserves reporting requirements. The management information circular to be prepared for the TransGlobe shareholder meeting will contain COGEH compliant reserves
disclosure for VAALCO and for TransGlobe and such information, including any combined reserves information contained therein, shall replace the estimates contained in this document. VAALCO and TransGlobe did not construct a consolidated
reserves report for the combined business. Therefore, the actual reserve of the combined business, may differ from the pro forma reserves for a number of reasons. U.S. GAAP to IFRS Differences The financial information of TransGlobe included
in this Presentation has been prepared in accordance with International Financial Reporting Standards (as promulgated by the International Accounting Standards Board) ("IFRS"). Certain differences exist between IFRS and GAAP, which might be
material to the financial information presented in this presentation. Important Information About the Proposed Arrangement and Where to Find It In connection with the proposed arrangement, VAALCO intends to file preliminary and definitive
proxy statements with the SEC. The preliminary and definitive proxy statements and other relevant documents will be sent or given to the stockholders of VAALCO as of the record date established for voting on the proposed arrangement and will
contain important information about the proposed arrangement and related matters. Stockholders of VAALCO and other interested persons are advised to read, when available, the preliminary proxy statement and any amendments thereto and, once
available, the definitive proxy statement, in connection with VAALCO’s solicitation of proxies for the meeting of stockholders to be held to approve, among other things, the issuance of shares of VAALCO’s common stock in connection with the

within the meaning of Section 27A of the Securities Act, Section 21E of the Securities Exchange Act of 1934, as amended, which are intended to be covered by the safe harbors created by those laws and other applicable laws and “forward-looking
information” within the meaning of applicable Canadian securities laws. Where a forward-looking statement expresses or implies an expectation or belief as to future events or results, such expectation or belief is expressed in good faith and
believed to have a reasonable basis. All statements other than statements of historical fact may be forward-looking statements. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “forecast,” “outlook,” “aim,” “target,” “will,”
“could,” “should,” “may,” “likely,” “plan,” “probably” or similar words may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements in this
Presentation include, but are not limited to, statements relating to (i) the proposed arrangement and its expected terms, timing and closing, including receipt of required approvals, if any, satisfaction of other customary closing conditions
and expected changes and appointments to the executive team and board of directors; (ii) estimates of pro-forma reserves and future drilling, production and sales of crude oil and natural gas; (iii) estimates of future cost reductions,
synergies, including pre-tax synergies, savings and efficiencies; (iv) expectations regarding VAALCO’s ability to effectively integrate assets and properties it may acquire as a result of the proposed arrangement into VAALCO’s operations; (v)
expectations regarding future exploration and the development, growth and potential of VAALCO’s and TransGlobe’s operations, project pipeline and investments, and schedule and anticipated benefits to be derived therefrom; (vi) expectations
regarding future investments or divestitures; (vii) expectations of future dividends and returns to stockholders including share buybacks; (viii) expectations of future balance sheet strength and credit ratings including pro forma financial
metrics; (ix) expectations future equity and enterprise value; (x) expectations regarding of the continued listing of VAALCO’s common stock on The New York Stock Exchange, and London Stock Exchange, and de-listing of TransGlobe’s shares from
Nasdaq, Toronto Stock Exchange and AIM; (xi) expectations regarding the percentage share of the combined company that are expected to be owned by existing VAALCO stockholders and TransGlobe shareholders; (xii) expectations of future plans,
priorities and focus and benefits of the proposed arrangement and the Combined Company; (xiii) the combined group's environmental, social and governance related focus and commitments, and the anticipated benefits to be derived therefrom; (xiv)
terms of hedging contracts; and (xv) expectations relating to resource potential and the potential to add reserves. Additionally, statements relating to “reserves” are deemed to be forward-looking statements, as they involve the implied
assessment, based on certain estimates and assumptions, that the reserves described exist in the quantities predicted or estimated and can be profitably produced in the future. Forward-looking statements regarding the percentage share of the
Combined Company that are expected to be owned by existing VAALCO stockholders and TransGlobe shareholders have been calculated based on each company’s vested outstanding shares as of the date of the Arrangement Agreement. Dividends of VAALCO
beyond Q3 2022 have not yet been approved or declared by the board of directors. VAALCO management’s expectations with respect to future dividends, annualized dividends or other returns to stockholders, including share buybacks, are
forward-looking statements. Investors are cautioned that such statements with respect to future dividends and share buybacks are non-binding. The declaration and payment of future dividends or the terms of any share buybacks remain at the
discretion of the board of directors of VAALCO and will be determined based on VAALCO’s financial results, balance sheet strength, cash and liquidity requirements, future prospects, crude oil and natural gas prices, and other factors deemed
relevant by the board of directors of VAALCO. The board of directors of VAALCO reserves all powers related to the declaration and payment of dividends. Consequently, in determining the dividend to be declared and paid on VAALCO common stock,
the board of directors of VAALCO may revise or terminate the payment level at any time without prior notice. Such forward-looking statements are subject to risks, uncertainties and other factors, which could cause actual results to differ
materially from future results expressed, projected or implied by the forward-looking statements. These risks and uncertainties include, but are not limited to: the ability to obtain shareholder, court and regulatory approvals (if any) of the
proposed arrangement; the ability to complete the proposed arrangement on anticipated terms and timetable; the possibility that various closing conditions for the arrangement may not be satisfied or waived; risks relating to any unforeseen
liabilities of VAALCO or TransGlobe; the tax treatment of the proposed arrangement in the United States and Canada; declines in oil or natural gas prices; the level of success in exploration, development and production activities; adverse
weather conditions that may negatively impact development or production activities; the timing and costs of exploration and development expenditures; inaccuracies of reserve estimates or assumptions underlying them; revisions to reserve
estimates as a result of changes in commodity prices; impacts to financial statements as a result of impairment write-downs; the ability to generate cash flows that, along with cash on hand, will be sufficient to support operations and cash
requirements; the ability to attract capital or obtain debt financing arrangements; currency exchange rates and regulations; actions by joint venture co-owners; hedging decisions, including whether or not to enter into derivative financial
instruments; international, federal and state initiatives relating to the regulation of hydraulic fracturing; failure of asses to yield oil or gas in commercially viable quantities; uninsured or underinsured losses resulting from oil and gas
operations; inability to access oil and gas markets due to market conditions or operational impediments; the impact and costs of compliance with laws and regulations governing oil and gas operations; the ability to replace oil and natural gas
reserves; any loss of senior management or technical personnel; competition in the oil and gas industry; the risk that the proposed arrangement may not increase VAALCO’s relevance to investors in the international E&P industry, increase
capital market access through scale and diversification or provide liquidity benefits for shareholders; and other risks described (i) under the caption “Risk Factors” in VAALCO’s 2021 Annual Report on Form 10-K, filed with the SEC on March 11,
2022; and (ii) in TransGlobe’s 2021 Annual Report on Form 40-F, filed with the SEC on March 17, 2022 or TransGlobe's annual information form for the year ended December 31, 2021 dated March 17, 2022. Neither VAALCO nor TransGlobe is affirming
or adopting any statements or reports attributed to the other (including prior oil and gas reserves information) in this Presentation or made by the other outside of this Presentation. More information on potential factors that could affect
VAALCO’s or TransGlobe’s financial results will be included in the preliminary and the definitive proxy statements that VAALCO intends to file with the SEC in connection with VAALCO’s solicitation of proxies for the meeting of stockholders to
be held to approve, among other things, the issuance of shares of VAALCO’s common stock in connection with the proposed arrangement. There may be additional risks that neither VAALCO nor TransGlobe presently knows, or that VAALCO or TransGlobe
currently believes are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect VAALCO’s and TransGlobe’s expectations, plans or
forecasts of future events and views as of the date of this Presentation. Should one or more of these risks or uncertainties materialize, or should any of the assumptions prove incorrect, actual results may vary in material respects from those
projected in these forward-looking statements. No obligation is being undertaken to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable
securities laws. Certain Assumptions Relating to Forward Looking Statements Forward-looking statements or information are based on a number of factors and assumptions which have been used to develop such statements and information but which
may prove to be incorrect. Although TransGlobe and VAALCO believe the expectations reflected in such forward-looking statements or information are reasonable, undue reliance should not be placed on forward-looking statements because TransGlobe
and VAALCO can give no assurance that such expectations will prove to be correct. Many factors could cause actual results to differ materially from those expressed or implied in any forward-looking statements contained herein. In addition to
other factors and assumptions which may be identified in this presentation, assumptions have been made regarding, among other things, anticipated production volumes; the timing of receipt of regulatory and shareholder approvals for the
arrangement; the ability of the combined business to realize the anticipated benefits of the arrangement; ability to effectively integrate assets and property as a result of the arrangement; ability to obtain qualified staff and equipment in a
timely and cost-efficient manner; regulatory framework governing royalties, taxes and environmental matters in the jurisdictions in which TransGlobe and VAALCO conducts and the combined business will conduct its business; future capital
expenditures; future sources of funding for capital programs; current commodity prices and royalty regimes; future exchange rates; the price of oil; the impact of increasing competition; conditions in general economic and financial markets;
availability of drilling and related equipment; effects of regulation by governmental agencies; future operating costs; uninterrupted access to areas of operation and infrastructure; recoverability of reserves and future production rates; the
combined business will have sufficient cash flow, debt and equity sources or other financial resources required to fund its capital and operating expenditures and requirements as needed; results of operations will be consistent with
expectations; current or, where applicable, proposed industry conditions, laws and regulations will continue in effect; the estimates of reserves and resource volumes and the assumptions related thereto are accurate in all material respects;
and other matters.
Slide 39 Disclaimers (cont.) Oil & Gas Advisories Relating to TransGlobe Reserves The estimates
of TransGlobe's December 31, 2021 reserves set forth in this presentation have been prepared by GLJ Ltd. (“GLJ”), an independent qualified reserves evaluator, as of December 31, 2021 in accordance with NI 51-101 and the COGEH and using the
forecast of prices, inflation and exchange rates computed using the average of the forecasts of GLJ Ltd., McDaniel & Associates Consultants Ltd. and Sproule Associates Limited each dated January 1, 2022. Drilling locations This
Presentation discloses drilling inventory in three categories: (i) proved locations; (ii) probable locations; and (iii) unbooked locations. Proved locations and probable locations are derived from GLJ Ltd.'s reserves evaluation as of December
31, 2021 and account for drilling locations that have associated proved and/or probable reserves, as applicable. Of the 80 drilling locations identified herein, 6 are proved locations, 13 are probable locations and 61 are unbooked
locations. Unbooked locations are internal estimates based on TransGlobe's prospective acreage and an assumption as to the number of wells that can be drilled per section based on industry practice and internal review. Unbooked locations do
not have attributed reserves or resources. Unbooked locations consist of drilling locations that have been identified by management as an estimation of TransGlobe's multi-year drilling activities based on evaluation of applicable geologic,
seismic, engineering, production and reserves information. There is no certainty that TransGlobe will drill all of these drilling locations and if drilled there is no certainty that such locations will result in additional oil and gas reserves,
resources or production. The drilling locations on which TransGlobe drills wells will ultimately depend upon the availability of capital, regulatory approvals, seasonal restrictions, oil and natural gas prices, costs, actual drilling results,
additional reservoir information that is obtained and other factors. While certain of the unbooked drilling locations have been de-risked by drilling existing wells in relative close proximity to such unbooked drilling locations, other unbooked
drilling locations are farther away from existing wells where management has less information about the characteristics of the reservoir and therefore there is more uncertainty whether wells will be drilled in such locations and if drilled
there is more uncertainty that such wells will result in additional oil and gas reserves, resources or production. "BOEs" may be misleading, particularly if used in isolation. A BOE conversion ratio of six thousand cubic feet of natural gas to
one barrel of oil equivalent (6 mcf: 1 bbl) is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Given that the value ratio based on the current
price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value. The estimates of reserves and future net revenue
for individual properties may not reflect the same confidence level as estimates of reserves and future net revenue for all properties, due to the effects of aggregation. Evercore Partners International LLP ("Evercore"), acts as financial
