PROXY STATEMENT/PROSPECTUS
 
December 29, 2008
 
Dear Willbros Group, Inc. Stockholder:
 
You are cordially invited to join us at a special meeting of stockholders of Willbros Group, Inc. to be held at the offices of Arias, Fabrega & Fabrega, P.H. Plaza 2000 Bldg., 16th Floor, 50th & 53rd Street, Panama City, Panama, on Monday, February 2, 2009, at 9:00 a.m. local time.
 
We are pleased to present for your approval a proposed merger for the purpose of reorganizing your company. As a result of the merger, Willbros Group, Inc. will become a direct, wholly-owned subsidiary of a newly formed Delaware corporation also named Willbros Group, Inc. and you will become a stockholder of the new Delaware corporation. The proposal is explained in the attached proxy statement/prospectus, which we encourage you to read.
 
If the merger is completed, Willbros Group, Inc., a Delaware corporation that we recently formed (which we refer to as Willbros Delaware), and its subsidiaries will continue to conduct the business now conducted by Willbros Group, Inc., a Republic of Panama corporation (which we refer to as Willbros Panama), and its subsidiaries. We believe the merger will facilitate our business strategies, including our shift in strategic focus to include North America as a principal market, and improve our access to U.S. capital markets and our funding and strategic flexibility, improve our access to U.S. government and private sector contracts and enhance our operational focus.
 
In the merger, a newly formed Delaware corporation that is a wholly-owned subsidiary of Willbros Delaware will be merged with and into Willbros Panama. Willbros Panama will be the surviving company and continue to exist. Willbros Delaware will become the direct parent holding company of Willbros Panama. In the merger, your shares of Willbros Panama common stock will automatically be converted into the right to receive shares of common stock of Willbros Delaware. The number of Willbros Delaware shares you will own will be the same as the number of Willbros Panama shares you own immediately prior to the completion of the merger, and your relative economic ownership in the company will remain unchanged. The shares of Willbros Delaware common stock will be listed on the New York Stock Exchange under the symbol “WG,” which is the same symbol under which your existing shares of Willbros Panama common stock are currently listed. In addition, the merger will generally be tax free for Willbros Panama stockholders.
 
This proxy statement/prospectus provides you with specific information about the special meeting and explains the reorganization proposal in more detail. We encourage you to read this entire document carefully. Please consider the risk factors beginning on page 10 before voting on the merger proposal.
 
The merger cannot be completed unless the holders of a majority of our outstanding shares of common stock on December 15, 2008, approve it. Our board of directors has carefully considered and approved the merger agreement and recommends that you vote “FOR” its adoption. Whether or not you plan on attending the special meeting in person, it is important that your shares be represented and voted. After reading the enclosed notice of special meeting and proxy statement/ prospectus, please sign, date and return the enclosed proxy card. We urge you to join us in supporting this important opportunity.
 
Sincerely yours,
 
-s- Randy R. Harl
Robert R. Harl

Chief Operating Officer

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
This proxy statement/prospectus, including the documents that we incorporate by reference, contain “forward-looking statements.” All statements, other than statements of historical facts, included or incorporated by reference in this proxy statement/prospectus that address activities, events or developments which we expect or anticipate will or may occur in the future, including such things as future capital expenditures (including the amount and nature thereof), oil, gas, gas liquids and power prices, demand for our services, the amount and nature of future investments by governments, expansion and other development trends of the oil, gas and power industries, business strategy, expansion and growth of our business and operations, the outcome of government investigations and legal proceedings and other such matters are forward-looking statements. These forward-looking statements are based on assumptions and analyses we made in light of our experience and our perception of historical trends, current conditions and expected future developments as well as other factors we believe are appropriate under the circumstances. However, whether actual results and developments will conform to our expectations and predictions is subject to a number of risks and uncertainties. As a result, actual results could differ materially from our expectations. Factors that could cause actual results to differ from those contemplated by our forward-looking statements include, but are not limited to, the following:
 
  •  curtailment of capital expenditures in the oil, gas, power, refining and petrochemical industries;
 
  •  the consequences we may encounter if the terms and conditions of our final settlements with the United States Department of Justice (“DOJ”) and the Securities and Exchange Commission (“the SEC”) are not complied with, including the imposition of civil or criminal fines, penalties, enhanced monitoring arrangements, or other sanctions that might be imposed by the DOJ and SEC;
 
  •  the commencement by foreign governmental authorities of investigations into the actions of our current and former employees, and the determination that such actions constituted violations of foreign law;
 
  •  difficulties we may encounter in connection with the previous sale and disposition of our Nigeria assets and Nigeria based operations, including obtaining indemnification for any losses we may experience if, due to the non-performance of Ascot, claims are made against any parent company guarantees we provided and which remained in place, in varying degrees, subsequent to the closing;
 
  •  the dishonesty of employees and/or other representatives or their refusal to abide by applicable laws and our established policies and rules;
 
  •  adverse weather conditions not anticipated in bids and estimates;
 
  •  project cost overruns, unforeseen schedule delays, and the application of liquidated damages;
 
  •  the occurrence during the course of our operations of accidents and injuries to our personnel, as well as to third parties, that negatively affect our safety record, which is a factor used by many clients to pre-qualify and otherwise award work to contractors in our industry;
 
  •  cancellation of projects, in whole or in part;
 
  •  failure to realize cost recoveries from projects completed or in progress within a reasonable period after completion of the relevant project;
 
  •  inability to hire and retain sufficient skilled labor to execute our current work, our work in backlog and future work we have not yet been awarded;
 
  •  inability to execute cost-reimbursable projects within the target cost, thus eroding contract margin but not contract income on the project;
 
  •  political or social circumstances impeding the progress of our work and increasing the cost of performance;
 
  •  failure to obtain the timely award of one or more projects;
 
  •  inability to identify and acquire suitable acquisition targets on reasonable terms;


iii


Table of Contents

 
  •  inability to obtain adequate financing;
 
  •  inability to obtain sufficient surety bonds or letters of credit;
 
  •  loss of the services of key management personnel;
 
  •  the demand for energy moderating or diminishing;
 
  •  downturns in general economic, market or business conditions in our target markets;
 
  •  changes in the effective tax rate in countries where our work will be performed;
 
  •  changes in applicable laws or regulations, or changed interpretations thereof;
 
  •  changes in the scope of our expected insurance coverage;
 
  •  inability to manage insurable risk at an affordable cost;
 
  •  the occurrence of the risk factors listed elsewhere or incorporated by reference in this proxy statement/prospectus; and
 
  •  other factors, most of which are beyond our control.
 
Consequently, all of the forward-looking statements made or incorporated by reference in this proxy statement/prospectus are qualified by these cautionary statements and there can be no assurance that the actual results or developments we anticipate will be realized or, even if substantially realized, that they will have the consequences for, or effects on, our business or operations that we anticipate today. Accordingly, you should not unduly rely on these forward-looking statements, which speak only as of the date of this proxy statement/prospectus. We undertake no obligation to publicly revise any forward-looking statement to reflect circumstances or events after the date of this proxy statement/prospectus or to reflect the occurrence of unanticipated events. You should, however, review the factors and risks we describe in the reports we file from time to time with the SEC. See “Where You Can Find More Information” on page 41.

QUESTIONS AND ANSWERS
 
When and where will the special meeting be held?
 
The special meeting will be held at the offices of Arias, Fabrega & Fabrega, P.H. Plaza 2000 Bldg., 16th Floor, 50th & 53rd Street, Panama City, Panama, on Monday, February 2, 2009, at 9:00 a.m. local time.
 
What is the transaction I am being asked to vote on at the special meeting?
 
You are being asked to vote on a proposal, which we refer to as the merger proposal, to approve the merger agreement for the purpose of reorganizing your company to change its place of incorporation from Panama to Delaware. As a result of the merger, Willbros Panama will become a wholly-owned subsidiary of Willbros Delaware, and you will become a stockholder of Willbros Delaware. The board of directors recommends you vote “FOR” this proposal.
 
How will the merger be accomplished?
 
Willbros Panama has formed a new, wholly-owned Delaware subsidiary, Willbros Delaware, which will, after the merger, become the new Delaware public parent company of the entire Willbros group of companies. A new Delaware company, Willbros Merger, Inc., which has been formed specifically for the merger and is owned by Willbros Delaware, will merge with and into Willbros Panama. Willbros Panama will be the surviving company in the merger and will become a direct, wholly-owned subsidiary of Willbros Delaware. Each share of Willbros Panama common stock outstanding immediately prior to the effective time of the merger will automatically convert into the right to receive a share of Willbros Delaware common stock. Willbros Delaware will continue to be engaged in the same business that Willbros Panama and its subsidiaries were engaged in before the merger. The additional steps in the merger are more fully described in “The Reorganization — Structure of the Merger” on page 13.
 
Why are we proposing this merger?
 
The merger is being proposed in order to reorganize the company as a Delaware corporation. In addition, if the merger proposal is approved at the special meeting and the merger consummated, we intend to effect an internal restructuring in connection with the reorganization to separate Willbros Panama from its subsidiary Willbros USA, Inc. (“Willbros USA”), so that Willbros USA will become a direct subsidiary of Willbros Delaware. When the company acquired its predecessor in 1992, it was anticipated that the operations of its subsidiaries would take place primarily outside the United States. However, due to deteriorating security, civil disturbances, adverse government actions, currency risks and potential political instability in certain oil-rich countries, we have in recent years focused our efforts in the North American market. While we will continue to seek international opportunities and serve customers in international locations, our reorganization in the United States as a Delaware corporation is more appropriate for our shift in strategic focus to include North America as a principal market. We believe our reorganization would enable us to (i) improve our access to the U.S. capital markets, increase funding and strategic flexibility and reduce the cost of capital, (ii) improve our access to U.S. government and private sector contracts, and (iii) better focus management efforts on each U.S. and international operation and better attract and retain key employees. Please read “The Reorganization — Reasons for the Reorganization” beginning on page 13.
 
What will happen to my existing shares of common stock of Willbros Panama in the merger?
 
Your Willbros Panama shares will automatically be converted into the right to receive the same number of shares of common stock of Willbros Delaware. As a result of the merger, you will become a stockholder of Willbros Delaware and will own the same number and percentage of shares of Willbros Delaware common stock that you now own of Willbros Panama common stock. The shares of Willbros Delaware will have substantially the same attributes as your existing shares of common stock of Willbros Panama and will be listed on the New York Stock Exchange under the symbol “WG,” which is the same symbol under which your existing shares of common stock of Willbros Panama are currently listed.

Table of Contents

Will the merger dilute my ownership interest?
 
No. The merger will not dilute your ownership interest. Immediately after the merger is consummated you will own the same percentage of Willbros Delaware common stock as you own of Willbros Panama common stock immediately prior to the completion of the merger.
 
Will I be taxed as a result of the merger?
 
We believe that the merger will generally be tax-free under U.S. federal income tax laws. We expect that you will not recognize any gain or loss for U.S. federal income tax purposes upon your receipt of Willbros Delaware common stock in exchange for your shares of Willbros Panama common stock in the merger. The tax consequences to you will depend on your own situation. You are urged to consult your own tax advisors concerning the specific tax consequences of the merger to you, including any foreign, state, or local tax consequences of the merger. For further information, see “Material Income Tax Consequences.”
 
Will Willbros Delaware or Willbros Panama be taxed as a result of the reorganization?
 
We believe that Willbros Delaware and Willbros Panama will not recognize gain or loss for U.S. federal income tax purposes in connection with consummation of the reorganization. However, changes in tax laws, treaties or regulations or the interpretation or enforcement of these tax laws, treaties or regulations, could adversely affect the tax consequences of the reorganization to Willbros Delaware, its subsidiaries and the stockholders of Willbros Delaware and its subsidiaries. In addition, if the U.S. Internal Revenue Service or other taxing authorities do not agree with our assessment of the effects or interpretation of these laws, treaties and regulations, this could have a material adverse effect on the tax consequences of the reorganization.
 
When do we expect to complete the merger?
 
We intend to complete the merger promptly after the stockholders of Willbros Panama approve the merger agreement at the special meeting, although the board of directors may delay completion of the merger for some period of time after stockholder approval pending receipt of third party consents or for other business reasons.
 
Why was Delaware selected as the place of incorporation of the new parent company?
 
The State of Delaware has adopted comprehensive, modern and flexible corporate laws which are updated and revised periodically to meet changing business needs. The corporation law of Delaware is widely regarded as the most extensive and well-defined body of corporate law in the United States. Delaware courts have developed considerable expertise in dealing with corporate issues, and a substantial body of case law has developed construing Delaware law and establishing public policies with respect to Delaware corporations.
 
Will the merger affect current operations? What about the future?
 
The merger will have no immediate major impact on how we conduct day-to-day operations. The location of future operations will generally depend on the needs of our business, independent of our place of incorporation. However, we are hopeful that the change in domicile from Panama to the U.S. to more appropriately reflect our shift in strategic focus to include North America as a principal market will, as previously discussed: (i) improve our access to capital markets, increase funding and strategic flexibility and reduce the cost of capital, (ii) improve our access to U.S. government and private sector contracts, and (iii) better focus management efforts on each U.S. and international operation and better attract and retain key employees.
 
What vote is required to approve the merger proposal?
 
In order for us to effect the merger, we need the affirmative vote of holders of a majority of all issued and outstanding shares of our common stock. Therefore, if you abstain or otherwise do not vote on the merger proposal, it will have the effect of a vote “against” the proposal. Please read “The Special Meeting — Vote Required for Approval” on page 19.


vi


Table of Contents

Will I be able to trade my shares during the time it takes to complete the merger?
 
Yes.
 
Do I have to exchange my stock certificates?
 
Yes. At the effective time of the merger, Willbros Delaware will cause certificates representing a sufficient number of shares of Willbros Delaware common stock to be deposited with an exchange agent for the purpose of enabling stockholders to exchange their Willbros Panama common stock for an equal number of shares of Willbros Delaware common stock. After the merger occurs, Mellon Investor Services, LLC, the exchange agent appointed by Willbros Delaware in connection with the merger, will send a letter of transmittal to stockholders of Willbros Panama that will provide instructions on these exchange procedures. Please do not send any stock certificates at this time. For further information, please read “The Reorganization — Share Conversion; Exchange of Shares” beginning on page 16.
 
Who is entitled to vote at the special meeting?
 
All holders of record of Willbros Panama common stock as of the close of business on December 15, 2008, the record date, are entitled to vote, or to grant proxies to vote, at the special meeting. On the record date, there were 39,145,111 shares of Willbros Panama common stock issued and outstanding. Each share of Willbros Panama common stock is entitled to cast one vote.
 
Who is soliciting these proxies?
 
Your vote and proxy is being solicited by Willbros Panama’s board of directors for use at the special meeting. This proxy statement/prospectus and enclosed proxy card are first being sent to stockholders beginning on or about December 31, 2008. In addition, Willbros Panama has retained Georgeson Inc. (“Georgeson”) to aid in the solicitation of proxies. For the services, Willbros Panama will pay Georgeson a fee of $10,000, plus out-of-pocket disbursements and expenses. This fee does not include the costs of preparing, printing, assembling, delivering and mailing the proxy materials. Solicitation of proxies may be made by mail, telephone, personal interviews or by other means by Willbros Panama’s board of directors or employees who will not be additionally compensated therefor, but who may be reimbursed for their out-of-pocket expenses in connection therewith. Proxy materials also will be furnished without cost to brokers and other nominees to forward to the beneficial owners of shares held in their names.
 
How do I vote if my shares are registered in my name?
 
By completing, signing and returning your proxy card in the enclosed postage-prepaid envelope, you will authorize the persons named on the proxy card to vote your shares according to your instructions. Please vote as soon as possible even if you currently plan to attend the meeting in person, so that your shares may be represented and voted at the special meeting.
 
How do I vote if my broker holds my shares in “street name”?
 
You should follow the voting instructions provided by your broker.
 
If my broker holds my shares in “street name,” will my broker vote my shares for me on the merger proposal?
 
If you do not provide your broker with instructions on how to vote your “street name” shares, your broker will not be permitted to vote them for or against the merger. You should complete and return the enclosed form of proxy or be sure to provide your broker with instructions on how to vote your shares.

Table of Contents

What do I do if I want to change my vote?
 
There are three ways in which you may revoke your proxy and change your vote:
 
  •  First, you may send a written notice to our proxy solicitor, Georgeson, stating that you would like to revoke your proxy. This notice must be received prior to the special meeting.
 
  •  Second, you may complete and submit a new, later-dated proxy by marking, signing and mailing a new proxy. The latest dated proxy actually received by Willbros Panama prior to the special meeting will be the one that is counted, and all earlier proxies will be revoked.
 
  •  Third, you may attend the special meeting and vote in person. Simply attending the meeting, however, will not revoke your proxy. At the special meeting, the chairman of the meeting will announce instructions for you to follow if you wish to revoke your proxy and vote in person at the meeting. If you have instructed a broker to vote your shares, you must follow the directions received from your broker to change or revoke your proxy.
 
What do I do if I receive multiple proxy cards?
 
If you receive multiple proxy cards, this indicates that your shares are held in more than one account, such as two brokerage accounts, and are registered in different names. You should vote each of the proxy cards to ensure that all of your shares are voted.
 
How will my shares be voted if I do not indicate how I wish to vote?
 
If you sign the proxy card but do not indicate how you wish to vote on the merger proposal, the persons named on the proxy card will vote FOR the approval of the merger agreement.
 
What will constitute a quorum at the special meeting?
 
The presence, in person or by proxy, of the holders of a majority of the shares issued, outstanding and entitled to vote will constitute a quorum at the special meeting. If you have properly signed and returned your proxy card by mail, you will be considered part of the quorum. Abstentions and broker non-votes will be counted for purposes of determining whether a quorum has been reached.

Recent Developments
 
Resolution of Criminal and Regulatory Matters
 
As previously disclosed, the May 2008 agreement in principle among the DOJ, Willbros Panama, and its subsidiary, Willbros International, Inc. (“WII”), to settle the DOJ’s investigation into violations of the Foreign Corrupt Practices Act (the “FCPA”), reached final approval by the DOJ. The terms of the final agreement are included in a Deferred Prosecution Agreement (the “DPA”), more fully described below, which, along with a six count criminal Information (the “Information”), was filed in the United States District Court, Southern District of Texas, Houston Division (the “Court”). When the requirements of the DPA are satisfied, the DOJ will dismiss the Information. Also in May 2008, a final agreement was reached by us with the SEC to resolve the SEC’s investigation into violations of the FCPA, the Securities Act of 1933, as amended (the “Securities Act”), and the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The final settlement with the SEC has been entered and approved by the Court. These investigations stemmed primarily from our former operations in Bolivia, Ecuador and Nigeria.
 
As described more fully below, the settlements together will require us to pay, over approximately three years, a total of $32.3 million in penalties and disgorgement of profits, plus post-judgment interest on $7.725 million of that amount. In addition, Willbros Panama and WII will, for a period of approximately three years, each be subject to the DPA with the DOJ. Finally, we will be subject to a permanent injunction barring future violations of certain provisions of the federal securities laws.
 
More specifically, the terms of the final settlement agreement concluded by Willbros Panama and WII on May 14, 2008, with the DOJ include the following:
 
  •  The six counts include conspiracy to violate the FCPA, violations of the FCPA’s anti-bribery provisions and violations of the FCPA’s books-and-records provisions. Willbros Panama and WII will face prosecution by the DOJ for the charges alleged in the Information, and possibly other charges as well, if they fail to comply with the DPA.
 
  •  The DPA requires, for the three-year term of the DPA, continued full cooperation with the DOJ in its investigation; continued implementation of a compliance and ethics program to prevent and detect violations of the FCPA and other anti-corruption laws; and continued review of existing internal controls, policies and procedures in order to ensure that Willbros Panama and WII maintain adequate controls and a rigorous anti-corruption compliance code.
 
  •  The DPA also requires Willbros Panama and WII, at their expense, to engage an independent monitor for three years to assess and make recommendations about their compliance with the DPA. The independent monitor selection process is now underway with the DOJ having taken under consideration the candidate for independent monitor proposed by us.
 
  •  Provided that Willbros Panama and WII comply with the DPA, the DOJ has agreed not to prosecute Willbros Panama or WII based on the conduct described in the DPA and to move to dismiss the Information after three years.
 
  •  As part of the DPA, we will pay $22.0 million in fines in four installments, consisting of the $10.0 million payment made at signing on May 14, 2008, and $4.0 million annually for three years thereafter, with no interest due on the unpaid amounts.
 
With respect to the final settlement agreement concluded by us on May 14, 2008, with the SEC:
 
  •  The SEC filed in the Court a Complaint (the “SEC Complaint”) and a proposed Agreed Final Judgment against us (the “Judgment”). Without admitting or denying the allegations in the SEC Complaint, we consented to the filing of the SEC Complaint and entry of the Judgment to resolve the SEC’s

  investigation. The SEC Complaint alleges civil violations of the FCPA’s anti-bribery provisions, the FCPA’s books-and-records and internal control provisions and various antifraud provisions of the Securities Act and the Exchange Act. Since approved by the Court, the Judgment now permanently enjoins us from violating the FCPA’s anti-bribery, books-and-records, and internal control provisions and certain antifraud provisions of the Securities Act and the Exchange Act.
 
  •  The Judgment requires us to pay $8.9 million for disgorgement of profits and $1.4 million of pre-judgment interest. The disgorgement and pre-judgment interest are payable in four equal installments of $2.575 million first on signing, and annually for three years thereafter. The first payment was made at signing on May 14, 2008. Post-judgment interest will be payable on the outstanding balance of $7.725 million.
 
The settlement agreements, and our obligations thereunder, will not be affected by the merger.
 
The Reorganization (Page 13)
 
The Merger.  Willbros Panama’s board of directors has approved and recommends that you adopt the merger agreement. The terms of the merger are set forth in the merger agreement attached as Annex A to this proxy statement/prospectus. As a result of the merger, you will own shares in a Delaware corporation rather than a Republic of Panama corporation. For a more detailed description of the differences between your rights under Delaware law and under Panama law, please read “Comparison of Rights of Stockholders of Willbros Panama Capital Stock and Willbros Delaware Capital Stock.” After completion of the merger, Willbros Delaware and its subsidiaries will continue to conduct the same business that Willbros Panama and its subsidiaries now conduct.
 
The merger involves the following steps:
 
  •  Merger Sub will merge with and into Willbros Panama. Willbros Panama will be the surviving entity and become a direct, wholly-owned subsidiary of Willbros Delaware (which we refer to herein as the merger or the “Merger”).
 
  •  In the merger, each outstanding share of common stock of Willbros Panama will automatically convert by operation of law into the right to receive one share of Willbros Delaware common stock. Stockholders of Willbros Panama will own exactly the same number of shares of Willbros Delaware common stock immediately after the merger as they owned in Willbros Panama immediately before the merger. In addition, each of the outstanding options and warrants to purchase shares of Willbros Panama common stock, if not exercised before the completion of the merger, will become options and warrants to acquire, at the same exercise price, an identical number of shares of Willbros Delaware common stock. Restricted stock units that are denominated in shares of Willbros Panama common stock will be denominated in an identical number of shares of Willbros Delaware common stock after the merger. For a description of the terms of the Willbros Delaware common stock, please read the discussion under “Description of Willbros Delaware Capital Stock.”
 
Stockholders will be required to exchange their stock certificate(s) as a result of the merger. Each outstanding certificate representing shares of Willbros Panama shall automatically represent the right to receive the same number of shares of Willbros Delaware common stock. Following the merger, certificates for shares of common stock of Willbros Delaware will be issued upon surrender of certificates for existing shares of common stock of Willbros Panama to an exchange agent appointed by Willbros Delaware. Please do not send any stock certificates at this time.
 
The Internal Spin-Off.  If the merger proposal is approved at the special meeting and the merger consummated, we intend to effect an internal restructuring pursuant to a spin-off in connection with the reorganization to separate Willbros Panama from its subsidiary Willbros USA, so that Willbros USA will become a direct subsidiary of Willbros Delaware (which we refer to herein as the internal spin-off or “Internal Spin-Off”, and together with the merger, constitute the reorganization or the “Reorganization”). The internal spin-off does not require the approval of the stockholders of Willbros Panama, and, accordingly, your proxy is not being solicited with respect to this transaction.

Table of Contents

The internal spin-off involves the following steps:
 
  •  Willbros Panama will distribute 60% of the outstanding common stock of Willbros USA to Willbros Delaware; and
 
  •  Willbros Panama will distribute all of the outstanding common stock of Musketeer Oil B.V., a Netherlands subsidiary holding company that owns the other 40% of the common stock of Willbros USA, to Willbros Delaware.
 
Reasons for the Reorganization (Page 13)
 
The merger is being proposed in order to reorganize the company as a Delaware corporation. When the company acquired its predecessor in 1992, it was anticipated that the operations of its subsidiaries would take place primarily outside the United States. However, due to deteriorating security, civil disturbances, adverse government actions, currency risks and potential political instability in certain oil-rich countries, we have in recent years focused our efforts in the North America market. While we will continue to seek international opportunities and serve customers in international locations, our reorganization in the United States as a Delaware corporation is more appropriate for our shift in strategic focus to include North America as a principal market. We believe our reorganization would enable us to (i) improve our access to the U.S. capital markets, increase funding and strategic flexibility and reduce the cost of capital, (ii) improve our access to U.S. government and private sector contracts, and (iii) better focus management efforts on each U.S. and international operation and better attract and retain key employees. For a discussion of the risk factors associated with the reorganization, please read the discussion under “Risk Factors” beginning on page 10.
 
Material Income Tax Consequences (Page 32)
 
We have requested and received a private letter ruling from the U.S. Internal Revenue Service to the effect that (i) the Merger qualifies as a reorganization under Section 368(a)(1)(B) of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) the Internal Spin-Off qualifies as a distribution under Section 355 of the Code (the “Reorganization Tax Ruling”). With respect to certain requirements for tax-free treatment under Section 355 of the Code on which the Internal Revenue Service does not rule, we have received an opinion of Sidley Austin LLP, our special U.S. tax counsel, to the effect that such requirements will be satisfied.
 
We believe that the Reorganization generally will be a tax-free transaction under U.S. federal income tax laws. We expect that you will not recognize any gain or loss for U.S. federal income tax purposes upon your receipt of Willbros Delaware common stock in exchange for your shares of Willbros Panama common stock in the Reorganization. In addition, we believe that no income, gain or loss will be recognized by Willbros Delaware, Willbros Panama or Merger Sub in connection with the Reorganization.
 
The Reorganization Tax Ruling and the opinion of our tax counsel are or will be based, in part, on assumptions and representations as to factual matters made by us, as requested by the Internal Revenue Service or counsel, which, if incorrect, could jeopardize the conclusions reached by the Internal Revenue Service and our tax counsel. The Reorganization Tax Ruling does not address certain material legal issues that could affect its conclusions, and reserves the right of the Internal Revenue Service to raise such issues upon a subsequent audit. The continuing validity of the Reorganization Tax Ruling and opinion of counsel is subject to the validity of certain representations and assumptions made in connection with obtaining the Reorganization Tax Ruling and opinion. If any of those assumptions or representations is inaccurate as of the effective time of the Merger or Internal Spin-Off, the tax consequences of the Merger or Internal Spin-Off could differ materially from those described above. We are not aware of any facts or circumstances that should cause such representations and assumptions to be inaccurate. Opinions of counsel neither bind the Internal Revenue Service or any court, nor preclude the Internal Revenue Service from adopting a contrary position.
 
If the Merger does not qualify as a tax-free reorganization under Section 368(a) of the Code, each Willbros Panama stockholder who receives Willbros Delaware common stock in exchange for Willbros Panama common stock would recognize taxable gain or loss equal to the difference between the fair market

Table of Contents

value of the Willbros Delaware common stock received and such stockholder’s basis in the Willbros Panama common stock exchanged therefor.
 
If the Internal Spin-Off does not qualify as a distribution under Section 355 of the Code, Willbros Panama would recognize gain in a taxable spin-off equal to the excess of the fair market value of the Willbros USA common stock distributed to Willbros Delaware over Willbros Panama’s tax basis in the Willbros USA common stock for U.S. federal income tax purposes. (Willbros Panama owns 60% of the outstanding stock of Willbros USA and all the outstanding stock of Musketeer Oil B.V., a Netherlands holding company that owns the other 40% of the outstanding stock of Willbros USA. Musketeer Oil B.V. is a disregarded entity for United States federal income tax purposes. Therefore, the Internal Spin-Off will be treated for such tax purposes as the distribution by Willbros Panama to Willbros Delaware of all the outstanding stock of Willbros USA.) In addition, Willbros Delaware’s receipt of the Willbros USA common stock in the Internal Spin-Off would be treated as the receipt of a taxable dividend in an amount equal to the fair market value of the Willbros USA common stock received to the extent of Willbros Panama’s current and accumulated earnings and profits (as increased to reflect any current income, including any gain, recognized by Willbros Panama on the taxable spin-off). Any amount that exceeded Willbros Panama’s earnings and profits would be treated first as non-taxable return of capital to the extent of Willbros Delaware’s tax basis in its Willbros Panama common stock with any remaining amounts being taxed as capital gain to Willbros Delaware.
 
The tax consequences to you will depend on your own situation. You are urged to consult your own tax advisors concerning the specific tax consequences of the reorganization to you, including any foreign, state, or local tax consequences of the reorganization. For further information, see “Material Income Tax Consequences.”
 
Comparison of Rights of Stockholders (Page 23)
 
The principal attributes of the existing Willbros Panama common stock and the Willbros Delaware common stock will be substantially similar. There are differences, however, between the rights of stockholders under Delaware law and stockholders under Panama law. In addition, there are differences between Willbros Panama’s articles of incorporation and by-laws and Willbros Delaware’s certificate of incorporation and bylaws. These differences include, among others, the following:
 
  •  Election of Directors.  Willbros Panama’s by-laws and Panama law require that directors be elected by the vote of the holders of a majority of the shares present in person or represented by proxy at a stockholders meeting. Willbros Delaware’s bylaws also generally require that directors be elected by the vote of the holders of a majority of the shares present or represented by proxy at a stockholders meeting; however, in the event of a contested election, the election of directors will be determined by a plurality vote.
 
  •  Stockholder Action by Written Consent.  Willbros Panama’s by-laws allow stockholders to take action by written consent without a meeting only by unanimous consent, which effectively results in restricting stockholders from taking action by written consent. As allowed under Delaware law, Willbros Delaware’s certificate of incorporation and bylaws prohibit stockholder action by written consent.
 
  •  Special Meetings of Stockholders.  Pursuant to Panama law and as provided in Willbros Panama’s by-laws, holders of 5% or more of Willbros Panama’s outstanding shares of voting stock may call a special meeting of the stockholders. Under Willbros Delaware’s bylaws, stockholders of Willbros Delaware will not be entitled to call a special meeting of the stockholders.
 
  •  Advance Notice Requirements for Stockholder Nominations and Other Proposals.  Under Willbros Panama’s articles of incorporation, any stockholder desiring to make a nomination for director at a meeting of stockholders must generally deliver notice of such nomination, containing prescribed information, to the corporate secretary not less than 45 nor more than 90 days before the meeting. The bylaws of Willbros Delaware require any stockholder desiring to make a nomination for director or a proposal for other business at a meeting of stockholders to generally deliver notice of such nomination


5


Table of Contents

  or proposal, containing prescribed information, to the corporate secretary not less than 90 nor more than 120 days before the meeting.
 
  •  Restrictions on Transfer of Common Stock.  Willbros Panama’s articles of incorporation provide for restrictions on any transfer of shares of common stock which would result in any person or persons becoming the beneficial owner of 10% or more of the outstanding shares of common stock in order to prevent Willbros Panama from becoming a “controlled foreign corporation” under United States tax law. No similar restrictions on the transfer of shares of common stock are contained in the certificate of incorporation of Willbros Delaware.
 
  •  Stockholder Rights Plan.  Willbros Panama has adopted a stockholder rights plan which gives holders of its common stock the right to purchase additional shares of Willbros Panama’s capital stock, or, in certain circumstances, shares of an acquirer’s stock, at a 50% discount if a potential acquirer purchases or announces a tender or exchange offer to purchase 15% or more of Willbros Panama’s common stock. The stockholder rights plan of Willbros Panama will be terminated immediately prior to the consummation of the proposed merger and will not be continued by Willbros Delaware. The board of directors of Willbros Delaware, however, will have the authority, as provided under Delaware law, to adopt a stockholder rights plan in the future should it determine such action is in the best interests of the company and its stockholders.
 
  •  Anti-Takeover Statute.  Under Panama law, Willbros Panama is currently not subject to any restrictions on business combinations. Willbros Delaware will be subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a publicly-held Delaware corporation from engaging in a merger, asset sale or other similar transaction with a person who owns, individually or with or through others, 15% or more of the corporation’s voting stock (an “interested stockholder”) for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the transaction is approved in a prescribed manner.
 
We encourage you to read the section titled “Comparison of Rights of Stockholders of Willbros Panama Capital Stock and Willbros Delaware Capital Stock” for a more detailed discussion of these differences.
 
Stock Exchange Listing (Page 18); Recent Stock Prices
 
Immediately following the merger, Willbros Delaware’s common stock will be listed on the New York Stock Exchange under the symbol “WG,” the same symbol under which Willbros Panama’s common stock is currently listed. The closing price per share of Willbros Panama’s common stock on the New York Stock Exchange was $7.78 on December 26, 2008. The high and low sales prices of Willbros Panama’s common stock on the New York Stock Exchange were $9.57 and $7.57 on November 11, 2008, the last trading day before the public announcement of the proposed merger.
 
No Dissenters’ or Appraisal Rights (Page 17)
 
You will not have dissenters’ or appraisal rights in connection with the merger.
 
Accounting Treatment of the Merger (Page 18)
 
The merger will be accounted for as a merger of entities under common control that will not result in changes in our historical consolidated carrying amounts of assets, liabilities and stockholders’ equity.
 
The Special Meeting (Page 18)
 
The special meeting will be held at the offices of Arias, Fabrega & Fabrega, P.H. Plaza 2000 Bldg., 16th Floor, 50th & 53rd Street, Panama City, Panama, on Monday, February 2, 2009, at 9:00 a.m. local time.
 
At the special meeting, the stockholders of Willbros Panama will be asked:
 
  •  to adopt the merger agreement; and


6


Table of Contents

 
  •  to approve postponements or adjournments of the special meeting, if necessary, to permit further solicitation of proxies in the event there are not sufficient votes at the time of the special meeting to adopt the merger agreement.
 
Record Date; Vote Required (Page 19)
 
You can vote at the special meeting of stockholders if you owned Willbros Panama common stock at the close of business on December 15, 2008, the record date. On that date, there were 39,145,111 shares of Willbros Panama common stock outstanding and entitled to vote.
 
Adoption of the merger agreement requires the affirmative vote of holders of a majority of the shares of Willbros Panama common stock issued and outstanding on the record date. Abstentions and broker non-votes will, therefore, effectively be counted as votes against adoption of the merger agreement.
 
Approval of any motion to adjourn or postpone the special meeting requires the affirmative vote of at least a majority of the shares of Willbros Panama common stock represented at the special meeting, whether or not a quorum is present. Abstentions and broker non-votes will not be counted as votes cast and will have no effect for purposes of determining whether a proposal to adjourn or postpone the special meeting is approved.
 
The board of directors of Willbros Panama has approved the merger agreement and recommends that you vote “FOR” its adoption.
 
Certain Financial Information
 
We have not included pro forma financial or comparative per share information concerning Willbros Panama that gives effect to the merger because, immediately after completion of the merger, the consolidated financial statements of Willbros Delaware will be substantially the same as Willbros Panama’s consolidated financial statements immediately prior to the merger and the merger will result in the conversion of each share of Willbros Panama common stock into the right to receive one share of Willbros Delaware common stock. Prior to the merger, Willbros Delaware will have no assets, liabilities or operations other than incident to its formation. Following completion of the merger, Willbros Panama’s 6.5% convertible senior notes due 2012 and 2.75% convertible senior notes due 2024 will become obligations of Willbros Delaware. As of September 30, 2008, there was an aggregate of approximately $32.1 million of the 6.5% convertible senior notes and approximately $59.4 million of the 2.75% convertible senior notes outstanding. In addition, Willbros Panama’s guarantee of the obligations under our $150.0 million senior secured credit facility will be replaced by the guarantee of Willbros Delaware upon completion of the merger.

RISK FACTORS
 
In considering whether to vote in favor of the merger proposal, you should consider all of the information we have included in this proxy statement/prospectus, including its Annexes, and all of the information included in the documents we have incorporated by reference. In addition, you should pay particular attention to the risks discussed in Willbros Panama’s annual report on Form 10-K for the year ended December 31, 2007, and quarterly report on Form 10-Q for the quarterly period ended September 30, 2008, and the risks described below.
 
If the Merger does not qualify as a tax-free reorganization under Section 368(a) of the Code, then you will recognize taxable gain or loss. If the Internal Spin-Off does not constitute a tax-free distribution under Section 355 of the Code, then we may be responsible for payment of significant U.S. federal income taxes.
 
The Reorganization Tax Ruling issued by the Internal Revenue Service and the opinions of counsel relating to the Reorganization are based, in part, on assumptions and representations as to factual matters made by us, as requested by the Internal Revenue Service or counsel, which, if incorrect, could jeopardize the conclusions reached by the Internal Revenue Service and counsel. The continuing validity of the Reorganization Tax Ruling and the opinions of counsel is subject to the validity of certain representations and assumptions made in connection with obtaining the Reorganization Tax Ruling and such opinions. If any of those assumptions or representations is inaccurate as of the effective time of the Merger and Internal Spin-Off, the tax consequences of the Merger and Internal Spin-Off could differ materially from those described herein. We are not aware of any facts or circumstances that should cause such representations and assumptions to be inaccurate.
 
The Reorganization Tax Ruling does not address certain material legal issues that could affect its conclusions, and reserves the right of the Internal Revenue Service to raise such issues upon a subsequent audit. Opinions of counsel neither bind the Internal Revenue Service or any court, nor preclude the Internal Revenue Service from adopting a contrary position. No assurance can be given that the Internal Revenue Service will not assert, or that a court would not sustain, a position contrary to any of those set forth herein.
 
If the Merger does not qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code, each Willbros Panama stockholder who receives Willbros Delaware common stock in exchange for Willbros Panama common stock would recognize taxable gain or loss equal to the difference between the fair market value of the Willbros Delaware common stock received and such stockholder’s basis in the Willbros Panama common stock exchanged therefor.
 
If the Internal Spin-Off does not qualify as a distribution under Section 355 of the Code, Willbros Panama would recognize gain in a taxable spin-off equal to the excess of the fair market value of the Willbros USA common stock distributed to Willbros Delaware over Willbros Panama’s tax basis in the Willbros USA common stock for U.S. federal income tax purposes. In addition, Willbros Delaware’s receipt of the Willbros USA common stock in the Internal Spin-Off would be treated as the receipt of a taxable dividend in an amount equal to the fair market value of the Willbros USA common stock received to the extent of Willbros Panama’s current and accumulated earnings and profits (as increased to reflect any current income, including any gain, recognized by Willbros Panama on the taxable spin-off). Any amount that exceeded Willbros Panama’s earnings and profits would be treated first as non-taxable return of capital to the extent of Willbros Delaware’s tax basis in its Willbros Panama common stock with any remaining amounts being taxed as capital gain to Willbros Delaware. (Willbros Panama owns 60% of the outstanding stock of Willbros USA and all the outstanding stock of Musketeer Oil B.V., a Netherlands holding company that owns the other 40% of the outstanding stock of Willbros USA. Musketeer Oil B.V. is a disregarded entity for United States federal income tax purposes. Therefore, the foregoing discussion reflects the fact that the Internal Spin-Off will be treated for such tax purposes as the distribution by Willbros Panama to Willbros Delaware of all the outstanding stock of Willbros USA.)

Table of Contents

Your rights as a stockholder may be adversely affected as a result of the merger.
 
Because of differences in Delaware law and Panama law and differences in the governing documents of Willbros Delaware and Willbros Panama, your rights as a stockholder will change if the merger is completed. For a description of these differences, please read “Comparison of Rights of Stockholders of Willbros Panama Capital Stock and Willbros Delaware Capital Stock.”
 
As with Willbros Panama, Willbros Delaware’s charter documents and Delaware law will contain provisions that may delay or prevent a third-party acquisition of Willbros Delaware, which may adversely affect the market price of Willbros Delaware common stock.
 
If the merger is completed, the certificate of incorporation and bylaws of Willbros Delaware will be the certificate of incorporation and bylaws of the company. Under these charter documents, the board of directors will retain the authority currently available to it to issue up to 1,000,000 shares of preferred stock and to determine the rights, preferences and restrictions, including the voting rights, of such shares without any vote or action by holders of the company’s common stock. The issuance of preferred stock could, among other things, adversely affect the voting power of the holders of Willbros Delaware’s common stock and, under certain circumstances, make it more difficult for a third party to gain control of Willbros Delaware.
 
In addition, the certificate of incorporation and bylaws of Willbros Delaware contain other provisions that may have the effect of delaying, deterring or preventing a change of control. For example, Willbros Delaware’s certificate of incorporation and bylaws:
 
  •  provide for a classified board of directors, which allows only one-third of the directors to be elected each year;
 
  •  restrict the ability of stockholders to take action by written consent;
 
  •  establish advance notice requirements for nominations for election to the board of directors; and
 
  •  prohibit stockholders from calling a special meeting of stockholders.
 
Willbros Delaware will not retain the current stockholder rights plan maintained by Willbros Panama. However, Willbros Delaware will be subject to Section 203 of the Delaware General Corporation Law. Section 203 of the Delaware General Corporation Law provides for a three-year moratorium on certain business combination transactions between a Delaware corporation, the shares of which are listed on a national securities exchange, and an “interested stockholder” (generally, a person who owns 15 percent or more of the corporation’s voting stock). An otherwise prohibited business combination may be permitted by board approval, by stockholder approval, or if upon consummation of the transaction which resulted in the stockholder becoming an “interested stockholder”, the interested stockholder owned at least 85 percent of the voting stock.
 
These provisions are designed to encourage potential acquirors to negotiate with the board of directors and provide the board of directors an opportunity to consider alternatives to increase stockholder value. These provisions are also intended to discourage certain tactics that may be used in proxy contests. However, the potential issuance of preferred stock, the certificate of incorporation and bylaw provisions and the restrictions in Section 203 of the Delaware General Corporation Law could discourage potential acquisition proposals and could delay or prevent a change of control, which may adversely affect the market price of the common stock of Willbros Delaware.
 
As with Willbros Panama, future sales of Willbros Delaware common stock may depress the stock price.
 
Sales of a substantial number of shares of Willbros Delaware’s common stock in the public market or otherwise, either by Willbros Delaware, a member of management or a major stockholder, or the perception that these sales could occur, may depress the market price of our common stock and impair Willbros Delaware’s ability to raise capital through the sale of additional equity securities.

Table of Contents

As with Willbros Panama, future sales of shares of common stock and shares of common stock issuable under outstanding warrants and convertible notes may lead to further dilution of Willbros Delaware’s issued and outstanding stock.
 
In November 2007, Willbros Panama completed an underwritten public offering of 7,906,250 shares of its common stock. In October 2006, Willbros Panama sold 3,722,360 shares of its common stock and warrants to purchase an additional 558,354 shares (of which, warrants to purchase 536,925 shares of common stock remained outstanding at September 30, 2008). The issuance of such warrants and the prior issuance by Willbros Panama of $70.0 million in aggregate principal amount of its 2.75% convertible senior notes due 2024 and $84.5 million of its 6.5% convertible senior notes due 2012 may cause a significant increase in the number of shares of common stock currently outstanding. In May 2007, Willbros Panama induced the conversion of approximately $52.5 million in aggregate principal amount of the outstanding 6.5% convertible senior notes into a total of 2,987,582 shares of its common stock. In addition, certain holders have exercised their right to convert the 2.75% convertible senior notes, converting approximately $10.6 million in aggregate principal amount of the 2.75% convertible senior notes into 546,633 shares of Willbros Panama’s common stock as of September 30, 2008. Following the merger, the 2.75% convertible senior notes and 6.5% convertible senior notes will become obligations of Willbros Delaware. As of September 30, 2008, 3,048,641 shares of common stock are issuable upon conversion of approximately $59.4 million in aggregate principal amount of the 2.75% convertible senior notes and 1,825,587 shares of common stock are issuable upon conversion of approximately $32.1 million in aggregate principal amount of the 6.5% convertible senior notes. If Willbros Delaware elects to induce the conversion of additional convertible notes or holders elect to convert additional convertible notes, there may be a significant increase in the number of shares of Willbros Delaware’s common stock outstanding.
 
As with Willbros Panama, Willbros Delaware’s authorized shares of common stock will consist of 70 million shares. The issuance of additional common stock or securities convertible into our common stock would result in further dilution of the ownership interest in us held by existing stockholders. In addition, as with Willbros Panama, Willbros Delaware will be authorized to issue, without stockholder approval, 1,000,000 shares of preferred stock, which may give other stockholders dividend, conversion, voting and liquidation rights, among other rights, which may be superior to the rights of holders of its common stock. While our board of directors has no present intention of issuing any such preferred stock, it reserves the right to do so in the future.
 
The anticipated benefits of our reorganization may not be realized.
 
We will incur additional direct costs and expenses related to the reorganization, including attorneys’ fees, accountants’ fees, financial printing expenses and filing fees. While we believe that the reorganization will result in operational, administrative and other benefits that significantly outweigh the related costs and expenses, we cannot assure you that those benefits will be realized.

THE REORGANIZATION
 
Structure of the Merger
 
The board of directors of Willbros Panama has approved and recommends that you adopt the merger agreement. Under the merger agreement, Merger Sub will merge with and into Willbros Panama. Willbros Panama will be the surviving company in the merger and become a direct subsidiary of Willbros Delaware. The terms of the merger are set forth in the merger agreement attached as Annex A to this proxy statement/prospectus. As a result of the merger, your shares of Willbros Panama common stock will automatically convert into the right to receive the same number of shares of Willbros Delaware common stock.
 
After completion of the merger, you will own an interest in a Delaware holding company which, through Willbros Delaware and its subsidiaries, will be engaged in the same business that Willbros Panama and its subsidiaries were engaged in prior to the merger.
 
The merger involves the following steps:
 
1. Merger Sub will merge with and into Willbros Panama. Willbros Panama will be the surviving entity and become a direct, wholly-owned subsidiary of Willbros Delaware.
 
2. In the merger, each outstanding share of common stock of Willbros Panama will automatically convert by operation of law into the right to receive one common share of Willbros Delaware. Stockholders of Willbros Panama will own exactly the same number of shares of Willbros Delaware common stock immediately after the merger as they owned in Willbros Panama immediately before the merger. For a description of the terms of the Willbros Delaware common stock, please read the discussion under “Description of Willbros Delaware Capital Stock.”
 
The Internal Spin-Off
 
If the merger proposal is approved at the special meeting and the merger consummated, we intend to effect an internal restructuring pursuant to the internal spin-off in connection with the reorganization to separate Willbros Panama from its subsidiary Willbros USA, so that Willbros USA will become a direct subsidiary of Willbros Delaware.
 
The internal spin-off involves the following steps:
 
  •  Willbros Panama will distribute 60% of the outstanding common stock of Willbros USA to Willbros Delaware; and
 
  •  Willbros Panama will distribute all of the outstanding common stock of Musketeer Oil B.V., a Netherlands subsidiary holding company that owns the other 40% of the common stock of Willbros USA, to Willbros Delaware.
 
Reasons for the Reorganization
 
The board of directors of Willbros Panama considered a number of factors in reaching its decision to recommend the merger proposal, which, if approved by the stockholders of Willbros Panama, will result in the reorganization of the company as a Delaware corporation. When the company acquired its predecessor in 1992, it was anticipated that the operations of its subsidiaries would take place primarily outside the United States. However, due to deteriorating security, civil disturbances, adverse government actions, currency risks and potential political instability in certain oil-rich countries, our business strategy to focus our resources in markets with the highest risk-adjusted returns has resulted in a change in focus to include North America as a principal market. For the year ended December 31, 2007, approximately 90% of our contract revenue was derived in North America. While we will continue to seek international opportunities and to serve customers in international locations, the board of directors of Willbros Panama believes forming a new public parent which is domiciled in the United States is more appropriate for our shift in strategic focus to include North America as a principal market. If the merger proposal is approved, prospective United States customers would no longer assume our Panama domicile is an indication that our primary focus and operations are


13


Table of Contents

outside the United States. Following the merger, Willbros Panama will be a wholly-owned subsidiary of Willbros Delaware and will operate as the parent company for all foreign subsidiaries of Willbros Delaware. Accordingly, we will continue to benefit from the use of Willbros Panama’s name, experience and goodwill in the international markets as we continue to seek international opportunities which may provide superior risk-adjusted returns.
 
In addition to the foregoing, the following potential business advantages resulting from Willbros Panama’s reorganization as a domestic Delaware holding corporation were additional factors taken into consideration by the board of directors in reaching its recommendation:
 
Improved Access to United States Capital Markets and Increased Flexibility.  Strategic acquisitions form an important part of our growth strategy, domestically and internationally. Willbros Panama has regularly been involved in various business acquisitions. Our losses in recent years have generally limited our ability to borrow from conventional lending institutions. In order to fund acquisitions, expansions, capital equipment purchases and ongoing operations, we have issued significant public debt and effected two public offerings and a private placement of our common stock since 2002, in certain cases on terms management considered less than ideal. The ability to raise needed funds in the public market on the best possible terms is essential to our overall growth strategy.
 
We believe the reorganization may improve our access to U.S. capital markets. It is our understanding that certain institutional investors have investment restrictions that limit or prohibit their investment in Panamanian companies and that other investors are wary of investing in companies organized in countries with whose laws they are not familiar. In addition, certain owners of businesses that we may be interested in acquiring for stock consideration may be reluctant to accept the stock of a Panamanian corporation rather than a U.S. corporation. By forming a new Delaware public parent company, we believe we may enhance our attractiveness and access to U.S. capital markets, thereby potentially allowing us to raise capital when needed more readily and on more favorable terms.
 
Improved Access to U.S. Government and Private Sector Contracts.  We are desirous of expanding our operations relating to the U.S. government contract sector. However, our current domicile in Panama may adversely affect our ability to expand such operations. Willbros Panama’s domicile in Panama and ultimate ownership of its domestic government contracting subsidiary may adversely affect our ability to obtain U.S. government contracts that will be subject to the restrictions and rules under the Buy America Act, the Trade Agreement Act, the Government Acquisition Regulations and National Industrial Security Program. Those factors may also preclude our work in the private sector on projects that may involve domestic security issues. We have been made aware of incidents of our competitors raising the foreign ownership of our domestic government contracting subsidiary as a factor in efforts to remove our subsidiary from consideration in competitive bids. The reorganization may improve our ability to secure additional contracts relating to the U.S. government contract sector by eliminating or limiting the effect of such potential roadblocks.
 
Improve Management Focus and Retention of Key Employees.  Immediately following the effective time of the merger, the ownership of Willbros USA, currently a subsidiary of Willbros Panama for conducting U.S. operations, will be distributed to Willbros Delaware in connection with the reorganization. As a result, Willbros Panama and Willbros USA will each become a separate direct subsidiary of Willbros Delaware. This separation will position each of Willbros Panama and Willbros USA to separately pursue business and financial strategies best suiting its long-term interests and should improve our overall management focus by permitting the management of Willbros Panama to focus exclusively on international operations and the management of Willbros USA to focus exclusively on U.S. operations. In addition, with Willbros Delaware as the public holding company and an organizational structure realigned with our operational structure, we believe our ability to attract and retain key management for our international and U.S. operations will be significantly improved.
 
Advantages as a Delaware Corporation.  As a Delaware corporation, our board of directors and management will be able to draw upon well-established principles of corporate governance in making legal and business decisions. Many publicly traded companies consider Delaware to be the most desirable


14


Table of Contents

jurisdiction in the United States in which to incorporate because of the state’s modern corporate laws and its history of dealing with a variety of corporate matters. Delaware has followed a policy of encouraging corporations to incorporate in that state, and in furtherance of that policy, has been a leader in adopting, construing and implementing comprehensive, flexible corporate laws. Both the Delaware legislature and courts have demonstrated an ability and willingness to act quickly and effectively to meet changing business needs. The Delaware courts have developed considerable expertise in dealing with corporate issues, and a substantial body of case law has developed construing Delaware law and establishing duties to the corporation and public policies with respect to corporate legal affairs.
 
Administrative Cost Savings.  The administrative services of Willbros Panama are performed primarily by employees of Willbros USA. The board of directors believes that forming a new Delaware public parent company should result in improved efficiency and administrative cost savings.
 
In addition to the potential benefits described above that were taken into consideration by the board of directors, differences between Panama and Delaware corporate law and the organizational documents of Willbros Panama and Willbros Delaware were taken into consideration. For a discussion of these differences, please see “Comparison of Rights of Stockholders.” After careful consideration, the board of directors of Willbros Panama has approved the merger proposal and the merger agreement and determined that the adoption of the merger agreement is advisable and in the best interest of Willbros Panama’s stockholders.
 
The board of directors of Willbros Panama recommends that stockholders vote “FOR” adoption of the merger agreement at the special meeting.
 
The Merger Agreement
 
Willbros Panama, Willbros Delaware and Merger Sub have entered into the merger agreement, which is the legal document that governs the merger. We recommend that you read carefully the complete merger agreement for the precise legal terms of the merger and other information that may be important to you. The merger agreement is included in this proxy statement/prospectus as Annex A and is incorporated in this document by reference.
 
Conditions to Consummation of the Merger
 
The merger will not be completed unless, among other things, the following conditions are satisfied or, if allowed by law, waived:
 
  •  the merger agreement is adopted by the affirmative vote of holders of a majority of the shares of Willbros Panama common stock outstanding and entitled to vote on the record date;
 
  •  the registration statement of which this proxy statement/prospectus is a part is declared effective by the Securities and Exchange Commission, and no stop order is in effect;
 
  •  the Willbros Delaware common stock to be issued in connection with the merger have been approved for listing on the New York Stock Exchange, subject to official notice of issuance, for at least 10 trading days prior to the effective time of the merger;
 
  •  all filings required to made with, and all material consents, approvals, permits and regulatory authorizations required to be obtained from, any court or governmental or regulatory authority or agency, or other person in connection with the delivery and consummation of the merger have been made or obtained, as the case may be; and
 
  •  no temporary restraining order, injunction or other order by any court or other legal restraint that, in the discretion of the board of directors of Willbros Panama, would make the consummation of the merger or any other transaction contemplated under the merger agreement inadvisable shall be in effect.
 
We are parties to agreements that require the consent of third parties prior to the implementation of the merger. We believe that we will obtain all material consents required prior to the completion of the merger


15


Table of Contents

and that the failure to obtain any other consents will not have a material impact on our business or our ability to consummate the merger.
 
Effectiveness of the Merger
 
If the merger agreement is adopted by the requisite vote of Willbros Panama stockholders, the merger will become effective on the later of the date and time at which a certificate of merger is filed with the Delaware Secretary of State and the merger agreement is filed and registered with the Public Registry Office of Panama (or at such later time as shall be agreed to by the parties). If the merger agreement is adopted, Willbros Panama expects to cause the merger to become effective promptly following the special meeting, although the board of directors may delay completion of the merger for some period of time after stockholder approval pending receipt of third-party consents or for other business reasons.
 
In the event the conditions to the merger are not satisfied, the merger may be abandoned or delayed even after the merger agreement has been adopted by our stockholders. In addition, the merger may be abandoned or delayed for any reason by the board of directors of Willbros Panama at any time prior to its becoming effective, even though the merger agreement has been adopted by our stockholders and all conditions to the merger have been satisfied.
 
Amendment or Termination of the Merger Agreement
 
The merger agreement may be amended, modified or supplemented at any time before or after its adoption by Willbros Panama stockholders. However, after adoption, no amendment, modification or supplement may be made or effected that does any of the following:
 
  •  alters or changes the amount or kind of shares to be received by Willbros Panama stockholders in the merger;
 
  •  alters or changes any term of the articles of incorporation of Willbros Panama; or
 
  •  alters or changes any other terms and conditions of the merger agreement if any of the alterations or changes, alone or in the aggregate, would adversely affect the holders of Willbros Panama common stock.
 
Willbros Panama’s board of directors may terminate the merger agreement and abandon the merger at any time prior to its effectiveness.
 
Share Conversion; Exchange of Shares
 
Each share of Willbros Panama common stock will automatically convert by operation of law into the right to receive one share of Willbros Delaware common stock upon the consummation of the merger. If you desire to sell some or all of your shares of Willbros Delaware common stock after the effective date of the merger, delivery to the exchange agent of the stock certificate(s) that previously represented shares of Willbros Panama common stock will be sufficient. Our exchange agent is Mellon Investor Services LLC, whose address is 480 Washington Blvd., 27th Floor, Jersey City, NJ 07310.
 
Willbros Delaware will appoint Mellon Investor Services LLC as exchange agent to handle the exchange of Willbros Panama stock certificates for Willbros Delaware common stock certificates.
 
Prior to or at the time of the merger, Willbros Delaware will cause certificates representing a sufficient number of shares of Willbros Delaware common stock to be deposited with the exchange agent for the purpose of enabling stockholders to exchange their Willbros Panama common stock for an equal number of shares of Willbros Delaware common stock. Soon after the closing of the merger, the exchange agent will send a letter of transmittal, which is to be used to exchange Willbros Panama stock certificates for Willbros Delaware stock certificates, to each former Willbros Panama stockholder. The letter of transmittal will contain instructions explaining the procedure for surrendering Willbros Panama stock certificates. You should not return stock certificates with the enclosed proxy card.


16


Table of Contents

Willbros Panama stockholders who surrender their stock certificates, together with a properly completed letter of transmittal, will receive stock certificates representing the shares of Willbros Delaware common stock. After the merger, each certificate that previously represented shares of Willbros Panama common stock will represent only the right to receive the shares of common stock of Willbros Delaware.
 
Although Willbros Delaware anticipates that it will not pay any cash dividends on its common stock for the foreseeable future, if it does pay any dividends, it will not pay dividends to holders of Willbros Panama stock certificates in respect of the common stock of Willbros Delaware into which the Willbros Panama shares represented by those certificates have been converted until the Willbros Panama stock certificates are surrendered to the exchange agent.
 
After the merger becomes effective, Willbros Panama will not register any further transfers of shares of the Willbros Panama common stock that were outstanding prior to the merger. Any certificates for Willbros Panama shares that you present for registration after the effective time of the merger will be exchanged for certificates for Willbros Delaware common stock.
 
If you surrender a Willbros Panama stock certificate and request the new Willbros Delaware certificate to be issued in a name other than the one appearing on the surrendered certificate, you must endorse the stock certificate or otherwise prepare it to be in proper form for transfer.
 
Management of Willbros Delaware
 
When the merger is completed, all of the directors and executive officers of Willbros Panama will be the directors and executive officers of Willbros Delaware.
 
Required Vote for the Merger
 
In order to complete the merger, the merger agreement must be adopted by the affirmative vote of holders of a majority of the shares of Willbros Panama common stock outstanding and entitled to vote on December 15, 2008. Because of this vote requirement, abstentions will have the same effect as votes against the proposal to adopt the merger agreement. The failure of a stockholder to submit a form of proxy or to vote in person at the meeting will also have the effect of a vote against the adoption of the merger agreement. Under the rules of the New York Stock Exchange, brokers who hold shares in “street name” for customers have the authority to vote on many “routine” proposals when they have not received instructions from beneficial owners. Under these rules, brokers are precluded from exercising their voting discretion with respect to proposals for non-routine matters like the merger. Thus, absent specific instructions from you, your broker is not empowered to vote your shares with respect to the merger proposal (i.e., “broker non-votes”). Because the affirmative vote of holders of a majority of the shares of Willbros Panama common stock is required for approval of the merger proposal, a broker non-vote will have the same effect as a vote “AGAINST” adoption of the merger agreement.
 
No Rights of Dissenting Stockholders
 
Under Panama law, you will not have “dissenters” or appraisal rights in connection with the merger.
 
Dividends
 
Since 1991, Willbros Panama has not declared or paid any cash dividends on its capital stock, except dividends in 1996 on its outstanding shares of preferred stock, which were converted into shares of its common stock on July 15, 1996. We anticipate that we will retain earnings to support operations and to finance growth and development of our business. Accordingly, if the merger agreement is adopted and the merger is completed, it is expected that Willbros Delaware will not pay any cash dividends on its common stock for the foreseeable future. In addition, the existing senior secured credit facility will prohibit the payment of cash dividends by Willbros Delaware on its common stock.

Table of Contents

Stock Compensation Plans And Employment Agreements
 
If the merger is completed, Willbros Panama will amend and revise its employee and director stock-based plans and arrangements to:
 
  •  provide that Willbros Delaware will assume sponsorship of such employee and director plans;
 
  •  provide that shares of Willbros Delaware common stock will be issued upon the exercise of any options or the payment of any other stock-based awards under the plans and arrangements; and
 
  •  otherwise appropriately reflect the substitution of common stock of Willbros Delaware for common stock of Willbros Panama under the plans and arrangements and related agreements.
 
Your approval of the merger will also constitute approval of those amendments and revisions to our stock option and other stock-based plans and arrangements providing for future use of Willbros Delaware common stock in lieu of common stock of Willbros Panama after the merger.
 
Stock Exchange Listing
 
Our common stock is currently listed on the New York Stock Exchange. There is currently no established public trading market for the common stock of Willbros Delaware. We will make an application so that, immediately following the merger, the common stock of Willbros Delaware will be listed on the New York Stock Exchange under the symbol “WG,” the same symbol under which Willbros Panama common stock is currently listed.
 
Accounting Treatment of the Merger
 
For accounting purposes, the merger will be accounted for as a merger of entities under common control. Accordingly, the historical consolidated financial position and results of operations of Willbros Panama will be included in the consolidated financial statements of Willbros Delaware on the same basis as currently presented.
 
THE SPECIAL MEETING
 
This proxy statement/prospectus is being furnished in connection with the solicitation of proxies from the holders of Willbros Panama common stock by the Willbros Panama board of directors relating to the merger and other matters to be voted upon at the special meeting and at any adjournment or postponement of the meeting. This proxy statement/prospectus is also a prospectus for Willbros Delaware common stock to be issued in connection with the merger. This proxy statement/prospectus, together with the form of proxy, is expected to be first mailed to stockholders on or about December 31, 2008. You should read this proxy statement/prospectus carefully before voting your shares.
 
When and Where the Special Meeting Will Be Held

Only Willbros Panama stockholders of record at the close of business on December 15, 2008, the record date, as shown in our records, will be entitled to vote, or to grant proxies to vote, at the special meeting. On the record date, there were 39,145,111 shares of Willbros Panama common stock outstanding and entitled to vote at the special meeting. For each proposal presented at the special meeting, you can cast one vote for each share of Willbros Panama common stock you owned on the record date.
 
Majority of Outstanding Shares Must Be Represented for a Vote to be Taken
 
In order to have a quorum, the holders of a majority of the shares of Willbros Panama common stock outstanding and entitled to vote on the record date must be represented in person or by proxy at the special meeting.
 
Vote Required for Approval
 
The merger agreement must be adopted by the affirmative vote of holders of a majority of the shares of Willbros Panama common stock issued, outstanding and entitled to vote on the record date. Abstentions and broker non-votes will, therefore, effectively be counted as votes against adoption of the merger agreement.
 
Approval of any motion to adjourn or postpone the special meeting requires the affirmative vote of at least a majority of the shares of Willbros Panama common stock represented at the special meeting, whether or not a quorum is present. Abstentions and broker non-votes will not be counted as votes cast and will have no effect for purposes of determining whether a proposal to adjourn or postpone the special meeting is approved.
 
Voting Your Shares
 
The Willbros Panama board of directors is soliciting proxies from the Willbros Panama stockholders. This will give you the opportunity to vote at the special meeting. When you deliver a valid proxy, the shares represented by that proxy will be voted in accordance with your instructions. If you do not vote by marking, signing and mailing your proxy card or by attending the special meeting and voting in person, it will have the same effect as voting against the adoption of the merger agreement.
 
Stockholders of record may vote by marking, signing and mailing their proxy card in the enclosed postage-prepaid envelope.
 
If you hold your Willbros Panama shares in the name of a bank, broker or other nominee, you should follow the instructions provided by your bank, broker or nominee when voting your shares. To be effective, a form of proxy must be received by us prior to the beginning of voting at the special meeting.

Changing Your Vote by Revoking Your Proxy
 
There are three ways in which you may revoke your proxy and change your vote:
 
  •  First, you may send a written notice to our proxy solicitor, Georgeson, stating that you would like to revoke your proxy. This notice must be received prior to the special meeting.
 
  •  Second, you may complete and submit a new later-dated proxy by marking, signing and mailing a new proxy. The latest dated proxy actually received by Willbros Panama prior to the special meeting will be the one that is counted, and all earlier proxies will be revoked.
 
  •  Third, you may attend the special meeting and vote in person. Simply attending the meeting, however, will not revoke your proxy. At the special meeting, the chairman of the meeting will announce instructions for you to follow if you wish to revoke your proxy and vote in person at the meeting.
 
If you have instructed a broker to vote your shares, you must follow the directions you receive from your broker to change or revoke your proxy.
 
How Proxies Are Counted
 
If you return a signed and dated proxy card but do not indicate how the shares are to be voted, those shares represented by your proxy card will be voted “FOR” the merger proposal. A valid proxy also gives the individuals named as proxies authority to vote in their discretion when voting the shares on any other matters that are properly presented for action at the special meeting. A properly executed proxy marked “ABSTAIN” will not be voted. However, it will be counted to determine whether there is a quorum present at the special meeting. Accordingly, because the affirmative vote of holders of a majority of the shares of Willbros Panama common stock entitled to vote at the special meeting is required to adopt the merger proposal, a proxy marked “ABSTAIN” will have the effect of a vote against this proposal. Broker non-votes (i.e., shares held in street name for customers by brokers or nominees which are represented at a meeting but with respect to which the broker or nominee is not empowered to vote on a particular proposal) will also be counted for purposes of determining whether there is a quorum at the special meeting. Under applicable stock exchange rules, brokers and nominees may not vote the shares that they hold beneficially either for or against the merger proposal without specific instructions from the person who beneficially owns those shares. Therefore, if your shares are held by a broker or other nominee and you do not give it instructions on how to vote your shares, this will have the same effect as voting against the merger proposal.
 
Cost of Solicitation
 
Willbros Panama will pay the cost of soliciting proxies. In addition to solicitation by mail, telephone or other means, Willbros Panama will make arrangements with brokerage houses and other custodians, nominees and fiduciaries to send proxy materials to beneficial owners. Willbros Panama will, upon request, reimburse these institutions for their reasonable expenses. Willbros Panama has retained Georgeson to aid in the solicitation of proxies. Willbros Panama will pay Georgeson a fee of $10,000 and reimburse Georgeson for its out-of-pocket disbursements and expenses in connection with its services.

Common Stock
 
As of the December 15, 2008, record date, 39,145,111 shares of Willbros Panama’s common stock were outstanding, which, upon completion of the merger, will convert to an equal number of shares of Willbros Delaware’s common stock. The holders of Willbros Delaware’s common stock are entitled to one vote for each share of common stock held on all matters voted upon by stockholders, including the election of directors. Holders of Willbros Delaware’s common stock have no right to cumulate their votes in the election of directors. Subject to the rights of any then-outstanding shares of Willbros Delaware’s preferred stock, the holders of Willbros Delaware’s common stock are entitled to receive dividends as may be declared in the discretion of the board of directors out of funds legally available for the payment of dividends. Willbros Delaware will be subject to restrictions on the payment of dividends under the provisions of the senior secured credit facility.
 
The holders of Willbros Delaware’s common stock are entitled to share equally and ratably in Willbros Delaware’s net assets upon a liquidation or dissolution after the payment or provision for all liabilities, subject to any preferential liquidation rights of any preferred stock that at the time may be outstanding. The holders of Willbros Delaware’s common stock have no preemptive, subscription, conversion or redemption rights.
 
Preferred Stock
 
Following the merger, Willbros Delaware will have no outstanding shares of preferred stock. The board of directors of Willbros Delaware may, without further approval of the stockholders, issue preferred stock from time to time in one or more series and fix the dividend rates and terms, conversion rights, voting rights, redemption rights and terms, liquidation preferences, sinking fund and any other rights, preferences, privileges and restrictions applicable to each series of preferred stock.
 
The specific matters that the board of directors may determine include the following:
 
  •  the designation of each series;
 
  •  the number of shares of each series;
 
  •  the rate of any dividends;
 
  •  whether any dividends will be cumulative or non-cumulative;
 
  •  the terms of any redemption;
 
  •  the amount payable in the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the company;
 
  •  rights and terms of any conversion or exchange;
 
  •  restrictions on the issuance of shares of the same series or any other series; and
 
  •  any voting rights.
 
The purpose of authorizing the board of directors to determine these rights, preferences, privileges and restrictions is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could:
 
  •  decrease the amount of earnings and assets available for distribution to holders of common stock;
 
  •  adversely affect the rights and powers, including voting rights, of holders of common stock; and
 
  •  have the effect of delaying, deferring or preventing a change in control.
 
For example, the board of directors, with its broad power to establish the rights and preferences of authorized but unissued preferred stock, could issue one or more series of preferred stock entitling holders to vote separately as a class on any proposed merger or consolidation, to convert preferred stock into a larger number of shares of common stock or other securities, to demand redemption at a specified price under prescribed circumstances related to a change in control, or to exercise other rights designed to impede a takeover.

Classified Board of Directors; Removal of Directors; Advance Notice Provisions for Stockholder Nominations
 
Willbros Delaware’s certificate of incorporation provides for the board of directors to be divided into three classes of directors serving staggered three-year terms, with the numbers of directors in the three classes to be as nearly equal as possible. Any director may be removed from office but only for cause and only by the affirmative vote of a majority of the then outstanding shares of stock entitled to vote on the matter. Any stockholder wishing to submit a nomination to the board of directors must follow the procedures outlined in Willbros Delaware’s bylaws. Any proposal to amend or repeal the provisions of Willbros Delaware’s certificate of incorporation relating to the matters contained above in this paragraph requires the affirmative vote of the holders of 75% or more of the outstanding shares of stock entitled to vote on the matter.

The purpose of authorizing the board of directors to determine these rights, preferences, privileges and restrictions is to eliminate delays associated with a stockholder vote on specific issuances.

The restrictions of Section 203 of the DGCL do not apply to corporations that have elected, in the manner provided therein, not to be subject to Section 203 of the DGCL or, with certain exceptions, that do not have a class of voting stock that is listed on a national securities exchange or held of record by more than 2,000 stockholders.

Indemnification and Insurance

Panama law does not address the extent to which a corporation may indemnify a director, officer or agent of the corporation. However, our Panama counsel has advised us that, under general agency principles, an agent, which would include directors and officers, may be indemnified against liability to third persons, except (i) under Article 64 of the General Corporation Law of Panama for a claim by creditors of the corporation against directors for authorizing a dividend or distribution of assets with knowledge that such payments impair the corporation’s capital or for making a false report or statement in any material respect or (ii) for losses due to gross negligence or malfeasance in the performance of such agent’s duties.

Under the DGCL, a corporation may indemnify a director, officer, employee or agent for fines, judgments or settlements, as well as expenses, in the context of third-party civil actions, so long as that person acted in good faith and in a manner that person reasonably believed to be in or not opposed to the best interest of the corporation. In a criminal action, a corporation may provide indemnification if that person, in addition, had no reasonable cause to believe the conduct was unlawful. In the context of derivative actions or other actions by or in right of the corporation, the corporation may provide indemnification for expenses only, except that if an officer, director, employee or agent is adjudged liable to the corporation, payment of expenses is not allowable unless a court deems the award of expenses appropriate. The foregoing determinations regarding indemnification are to be made, unless otherwise ordered by a court, by the majority vote of disinterested directors, even if less than a quorum, or a committee of the disinterested directors or, if there are no disinterested directors, or if the disinterested directors so direct, by independent legal counsel or by the stockholders. The DGCL mandates indemnification for expenses incurred by an officer or director in connection with a successful defense, on the merits or otherwise, of a proceeding against that person for actions in his or her capacity as an officer or director of the corporation. Willbros Delaware will advance defense expenses; however, a director or officer to whom such expenses are advanced must

Panama law provides that, in the absence of a contrary provision contained in the articles of incorporation or by-laws, the directors have the power to enact, amend, supersede and repeal the by-laws. Willbros Panama’s articles of incorporation and by-laws provide that the board of directors may make, alter, amend or repeal the by-laws; however, the by- laws of Willbros Panama provide that any amendments to the by- laws may be repealed by the stockholders.   Under the DGCL, the power to adopt, amend or repeal the bylaws is conferred upon the stockholders; however, a corporation may in its certificate of incorporation also confer upon the board of directors the power to adopt, amend or repeal the bylaws, provided that such power shall not divest or limit the power of the stockholders to adopt, amend or repeal the bylaws. The certificate of incorporation and bylaws of Willbros Delaware grant the board of directors the power to adopt, amend and repeal the bylaws.

Approval of Mergers or Consolidations and Other Transactions
Under Panama law and the articles of incorporation of Willbros Panama, a merger or the sale, lease or exchange of all or substantially all of a corporation’s assets requires the approval of stockholders owning a majority of the outstanding capital stock entitled to vote thereon.   Under the DGCL, unless otherwise provided in the certificate of incorporation, a sale or disposition of all or substantially all of a corporation’s assets, a merger or a consolidation of the corporation with another corporation requires, with certain exceptions, the affirmative vote of a majority of the outstanding shares entitled to vote on the matter. Willbros Delaware’s certificate of incorporation does not contain voting requirements for extraordinary corporate transactions different from or in addition to the approvals under the DGCL.
   
 
Furthermore, under Section 251 of the DGCL, unless otherwise provided in a corporation’s certificate of incorporation, approval of the stockholders of a surviving corporation in a merger is not required if:
   
 
•     the plan of merger does not amend in any respect the certificate of incorporation of the surviving corporation;
   
 
•     the shares outstanding immediately before the effectiveness of the merger are not changed by the merger; and
   
 
•     either (i) no shares of common stock of the surviving corporation and no shares, securities or obligations convertible into such common stock are to be issued or delivered under the plan of merger or (ii) the authorized unissued shares or treasury shares of the surviving corporation to be issued under the plan of merger plus those initially issuable upon conversion of any other shares, securities or obligations to be issued under the plan do not exceed 20% of the shares of common stock of the surviving corporation outstanding immediately prior to the merger.
 
Stockholder Rights Plan
Willbros Panama has adopted a stockholder rights plan pursuant to which each outstanding share of common stock includes an attached preferred stock purchase right (a “Right”). Each Right, when it becomes exercisable, entitles the registered holder to purchase, for $30 (the “Purchase Price”), one one-thousandth of a share of Series A junior participating preferred stock. The Rights become exercisable upon the earlier of:
  The stockholder rights plan of Willbros Panama will be terminated immediately prior to the consummation of the proposed merger.
 
•     the public announcement that a person or group has acquired 15% or more of the outstanding shares of common stock, except in connection with an offer approved by the board of directors of Willbros Panama; or
•   10 days after the commencement of, or announcement of an intention to commence, a tender or exchange offer that would result in a

person or group acquiring 15% or more of the outstanding shares of common stock.
   
 
If any person or group acquires 15% or more of the outstanding shares of common stock, except in connection with an offer approved by the board of directors, holders of the Rights, except the acquiring person or group, may purchase, for the Purchase Price, that number of shares of common stock or Series A junior participating preferred stock having a value equal to two times the Purchase Price. If, after the Rights have become exercisable, (i) Willbros Panama is acquired in a merger or other business combination in which its stockholders immediately prior to the transaction are not the holders of all of the surviving corporation’s voting power or (ii) more than 50% of the assets or earning power of Willbros Panama is sold, then each Right will entitle the holder to purchase, for the Purchase Price, a number of shares of common stock of the acquiring party having a value equal to two times the Purchase Price.
   
 
In the event shares of Series A junior participating preferred stock are issued upon exercise of the Rights, holders of the preferred stock will be entitled to (i) receive, in preference to holders of common stock, a quarterly dividend payment in an amount per share equal to the greater of $10.00 or 1,000 times the dividend declared per share of common stock; (ii) a minimum liquidation preference of $1,000 per share and after holders of common stock receive a liquidation payment of $1.00 per share, the holders of the preferred stock and the holders of common stock will share in the remaining assets in the ratio of 1,000 to 1 (as adjusted) for each share of preferred stock and common stock so held, respectively; and (iii) 1,000 votes per share, voting together with holders of the common stock.
   
 
The stockholder rights plan has certain anti-takeover effects. The plan discourages hostile takeovers by effectively allowing Willbros Panama stockholders to acquire shares of capital stock at a discount following a hostile acquisition of a large block of the outstanding common stock of Willbros Panama and by increasing the value of the consideration to be received by stockholders in specified transactions following an acquisition.
   
 
Anti-Takeover Statutes
Under Panama law, according to Decree No. 45 of December 5, 1977 (“Decree No. 45”), as amended, no takeover which would result in the acquisition by the offeror of 5% or more of the shares having a market value of at least $5,000,000 will be valid in case of a   Section 203 of the DGCL provides for a three-year moratorium on certain business combinations with “interested stockholders” (generally, persons who own, individually or with or through other persons, 15% or more of the corporation’s outstanding voting

As provided in Decree No. 45, the transfer of shares is also invalid if made in connection with a takeover offer of the nature described above. Decree No. 45 also provides that certain poison pill provisions may not be created by companies that have more than 3,000 stockholders unless they are registered with the National Securities Commission of Panama and satisfy the conditions of (ii) and (iii) above no less than six months prior to receipt of a takeover offer. The provisions of Decree No. 45 have the effect of restricting and limiting a takeover action. Decree No. 45 does not currently apply to Willbros Panama.   stock). This moratorium, or prohibition, on mergers, consolidations, and other transactions is subject to the following exceptions: (a) the business combination or transaction in which the stockholder becomes an interested stockholder is approved by the board of directors of the corporation prior to the stockholder becoming an interested stockholder; (b) the business combination is with an interested stockholder who became an interested stockholder in a transaction whereby such interested stockholder acquired at least 85% of the corporation’s voting stock, excluding shares held by directors who are also officers and by certain employee stock plans; or (c) the business combination is approved by the corporation’s board of directors and is authorized at a meeting by the affirmative vote of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder. However, the DGCL permits a corporation to opt out of the restrictions imposed by Section 203 in its certificate of incorporation. Willbros Delaware has not opted out of Section 203 in its certificate of incorporation.
 
Dissenters’ (Appraisal) Rights
Neither Panama law nor the articles of incorporation of Willbros Panama provide for dissenters’ appraisal rights. Therefore, stockholders of Willbros Panama are not entitled to dissenters’ appraisal rights.   The DGCL provides dissenters’ appraisal rights only in the case of a stockholder objecting to certain mergers or consolidations. Delaware law, however, does not afford dissenters’ appraisal rights with respect to (a) a sale of assets, (b) stock of a corporation surviving a merger if no vote of the surviving corporation’s stockholders is required to approve the merger (i.e., in case where the certificate of incorporation of surviving corporation is not changed in the merger and the stock to be issued in the merger does not exceed 20% of the stock outstanding prior to the merger), or (c) stock of a corporation in a merger or consolidation if the stock is (i) listed on a national securities exchange or designated as national market system securities or (ii) held of record by more then 2,000 holders; provided, however, the exception in (c) does not apply if holders receive in the transaction anything other than cash or securities that meet the requirements of (i) or (ii) or shares of the surviving corporation, or any combination of the foregoing.

Tax Consequences of the Reorganization to a U.S. Holder
 
The following is a summary of certain U.S. federal income tax consequences to a “U.S. holder” (defined below) of the Willbros Panama common stock and Willbros Panama convertible notes from the receipt of Willbros Delaware common stock or Willbros Delaware convertible notes in exchange for such U.S. holder’s Willbros Panama common stock or Willbros Panama convertible notes in the Reorganization as a result of the Merger. The following discussion summarizes certain rulings issued by the Internal Revenue Service in the Reorganization Tax Ruling and the opinion of Sidley Austin LLP, our special U.S. tax counsel, as to certain material U.S. federal income tax consequences with respect to the Reorganization. The Reorganization Tax Ruling and opinion of Sidley Austin LLP are based, in part, on assumptions and representations as to factual matters that have been or will be provided by us, as requested by the Internal Revenue Service and counsel. If any of those assumptions or representations is inaccurate as of the effective time of the Reorganization, the tax consequences of the Reorganization could differ materially from those described herein. We are not aware of any facts or circumstances that should cause such representations and assumptions to be untrue. Opinions of counsel neither bind the Internal Revenue Service or any court, nor preclude the Internal Revenue Service from adopting a contrary position.
 
This summary addresses only those of you who hold your shares of Willbros Panama common stock and Willbros Panama convertible notes, and will, after the Reorganization, hold your shares of Willbros Delaware common stock and Willbros Delaware convertible notes, as capital assets within the meaning of Section 1221 of the Code. This summary is limited to the U.S. federal income tax consequences of the Reorganization and does not address all the U.S. federal income tax consequences that may be relevant to you in light of your particular tax circumstances. Further, this summary does not address holders of Willbros Panama common stock or Willbros Panama convertible notes who are subject to special treatment under U.S. federal income tax laws, such as:
 
  •  tax-exempt organizations;
 
  •  S corporations and other pass-through entities and owners thereof;
 
  •  entities taxable as partnerships for U.S. federal income tax purposes and owners thereof;
 
  •  insurance companies and other financial institutions;
 
  •  mutual funds;
 
  •  dealers in stocks and securities;
 
  •  traders or investors in our common stock who elect the mark-to-market method of accounting for such stock;
 
  •  stockholders who received our common stock from the exercise of employee stock options or otherwise as compensation;
 
  •  stockholders who hold our common stock in a tax-qualified retirement plan, individual retirement account or other qualified savings account;
 
  •  stockholders who hold their shares of our common stock as part of a hedge, straddle, or a constructive sale or conversion transaction or other risk reduction or integrated investment transaction;
 
  •  a stockholder who actually or constructively owns more than 5% of Willbros Panama common stock; and
 
  •  stockholders who are not “U.S. holders”.
 
You are a “U.S. holder” if you are a beneficial owner of the shares of Willbros Panama common stock or the Willbros Panama convertible notes and you are, for U.S. federal income tax purposes, (i) a citizen or resident of the United States, (ii) a corporation, or an entity treated as a corporation, formed under the laws of the United States or any state thereof (including the District of Columbia), (iii) an estate, the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) in general, a trust if a court within

the United States is able to exercise primary supervision over the administration of the trust and one or more “United States persons” have the authority to control all substantial decisions of the trust.
 
Holders of the Willbros Panama common stock or Willbros Panama convertible notes who are not U.S. holders may have different tax consequences than those described below and are urged to consult their own tax advisors regarding the tax treatment to them under U.S. and non-U.S. tax laws.
 
If an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes holds Willbros Panama common stock or Willbros Panama convertible notes, the tax treatment of a partner in such entity generally will depend on the status of the partners and the activities of the partnership. If you are a partner in a partnership holding Willbros Panama common stock or Willbros Panama convertible notes, you are urged to consult your tax advisor.
 
Tax Consequences of the Merger
 
We have requested and received rulings from the Internal Revenue Service relating to the treatment of the Merger, Internal Spin-Off and certain related transactions for U.S. federal income tax purposes (the “Reorganization Tax Ruling”). The Reorganization Tax Ruling provides, in part, that the Merger of Merger Sub with and into Willbros Panama (as described under “The Reorganization — Structure of the Merger”) qualifies as a Reorganization under Section 368(a)(1)(B) of the Code.
 
Subject to the qualifications discussed herein, the Reorganization Tax Ruling provides as follows:
 
  •  No gain or loss will be recognized by a U.S. holder solely as the result of the receipt of Willbros Delaware common stock in exchange for such U.S. holder’s Willbros Panama common stock pursuant to the Merger;
 
  •  The aggregate tax basis of the Willbros Delaware common stock that a U.S. holder receives in the Merger will be the same as the aggregate tax basis of the shares of Willbros Panama common stock surrendered;
 
  •  The holding period of the Willbros Delaware common stock received by a U.S. holder in the Merger will include the holding period of the U.S. holder’s Willbros Panama common stock, provided that the Willbros Panama common stock is held as a capital asset on the date of the Merger;
 
  •  A U.S. holder of Willbros Panama convertible notes, warrants or options will not recognize gain or loss on the exchange of such convertible notes, warrants or options for convertible notes, warrants or options, respectively, of Willbros Delaware with identical terms, provided in the case of the convertible notes that they are treated as “securities” within the meaning of Section 354 of the Code; and
 
  •  No gain or loss will be recognized by Willbros Delaware, Willbros Panama or Merger Sub in the Merger.
 
The Reorganization Tax Ruling is based on representations as to factual matters that were provided by us to the Internal Revenue Service and on certain assumptions. If any of those representations or assumptions is inaccurate as of the effective time of the Merger, the tax consequences of the Merger could differ materially from those described above.
 
The Reorganization Tax Ruling does not address certain material legal issues that could affect its conclusions, and reserves the right of the Internal Revenue Service to raise such issues upon a subsequent audit. Sidley Austin LLP, our special tax counsel, has provided certain opinions to us regarding matters relating to the Merger that are not addressed by the Reorganization Tax Ruling. Such opinions are as follows:
 
  •  The Willbros Panama convertible notes should be treated as “securities” within the meaning of Section 354 of the Code and the U.S. holders thereof should therefore recognize no gain or loss on the exchange of such convertible notes for convertible notes of Willbros Delaware;


34


Table of Contents

 
  •  The aggregate tax basis of the Willbros Delaware convertible notes that a U.S. holder receives in the Merger should be the same as the aggregate tax basis of the Willbros Panama convertible notes surrendered; and
 
  •  The holding period of the Willbros Delaware convertible notes received by a U.S. holder in the Merger should include the holding period of the U.S. holder’s Willbros Panama convertible notes provided that the Willbros Panama convertible notes are held as a capital asset on the date of the Merger.
 
In addition, Sidley Austin LLP has provided an opinion that the material U.S. federal income tax consequences of the Merger to the U.S. holders of Willbros Panama common stock and to Willbros Panama, Willbros Delaware and Merger Sub are addressed in the Reorganization Tax Ruling. The opinions of Sidley Austin LLP are based on representations as to factual matters that were provided by us and on certain assumptions. If any of those representations or assumptions is inaccurate as of the effective time of the Merger, the tax consequences of the Merger could differ materially from those described above. Opinions of counsel neither bind the Internal Revenue Service or any court, nor preclude the Internal Revenue Service from adopting a contrary position.
 
If the Merger does not qualify as a reorganization under Section 368(a) of the Code, each U.S. holder would recognize taxable gain or loss equal to the difference between the fair market value of the Willbros Delaware common stock or Willbros Delaware convertible notes received in the Reorganization and such U.S. holder’s basis in the Willbros Panama common stock or Willbros Panama convertible notes, respectively, exchanged therefor.
 
Tax Consequences of the Internal Spin-Off
 
The Reorganization Tax Ruling provides, in part, that the distribution of the Willbros USA common stock by Willbros Panama to Willbros Delaware in the Internal Spin-Off (as described under “The Reorganization — The Internal Spin-Off”) qualifies as a distribution under Section 355 of the Code. Subject to the qualifications discussed herein, the Reorganization Tax Ruling provides as follows:
 
  •  No gain or loss will be recognized by Willbros Panama on the distribution of the Willbros USA common stock to Willbros Delaware in the Internal Spin-Off; and
 
  •  No gain or loss will be recognized by Willbros Delaware on its receipt of the Willbros USA common stock in the Internal Spin-Off except for any income inclusion that would arise as the result of Willbros Panama having been a “controlled foreign corporation” under the Code.
 
As discussed below, Sidley Austin LLP has provided an opinion that Willbros Panama has not been a controlled foreign corporation prior to the Merger and accordingly, no gain or loss should be recognized by (and no amount should otherwise be included in the income of) Willbros Delaware on its receipt of the Willbros USA common stock in the Internal Spin-Off.
 
The Reorganization Tax Ruling is based on representations as to factual matters that were provided by us to the Internal Revenue Service and on certain assumptions. If any of those representations or assumptions is inaccurate as of the effective time of the Internal Spin-Off, the tax consequences of the Internal Spin-Off could differ materially from those described above.
 
The Reorganization Tax Ruling does not address certain material legal issues that could affect its conclusions, and reserves the right of the Internal Revenue Service to raise such issues upon a subsequent audit. Sidley Austin LLP, our special tax counsel, has provided certain opinions to us regarding matters relating to the Internal Spin-Off that are not addressed by the Reorganization Tax Ruling. Such opinions are as follows:
 
  •  The Internal Spin-Off will be treated as satisfying the business purpose requirement described in Treas. Reg. § 1.355-2(b)(1);


35


Table of Contents

 
  •  The Internal Spin-Off will not be treated as being used principally as a device for the distribution of earnings and profits of Willbros Panama or Willbros USA or both under Section 355(a)(1)(B) of the Code;
 
  •  The Internal Spin-Off will not be taxable as a result of the application of Section 355(e) of the Code; and
 
  •  Willbros Panama has not been a controlled foreign corporation prior to the Merger and accordingly, no gain or loss should be recognized by (and no amount should otherwise be included in the income of) Willbros Delaware on its receipt of the Willbros USA common stock in the Internal Spin-Off.
 
In addition, Sidley Austin LLP has provided an opinion that the material U.S. federal income tax consequences of the Internal Spin-Off to Willbros Panama and Willbros Delaware are addressed in the Reorganization Tax Ruling. The opinions of Sidley Austin LLP are based on representations as to factual matters that were provided by us and on certain assumptions. If any of those representations or assumptions is inaccurate as of the effective time of the Internal Spin-Off, the tax consequences of the Internal Spin-Off could differ materially from those described above. Opinions of counsel neither bind the Internal Revenue Service or any court, nor preclude the Internal Revenue Service from adopting a contrary position.
 
If the Internal Spin-Off does not qualify as a distribution under Section 355 of the Code, Willbros Panama would recognize gain in a taxable spin-off equal to the excess of the fair market value of the Willbros USA common stock distributed to Willbros Delaware over Willbros Panama’s tax basis in the Willbros USA common stock for U.S. federal income tax purposes. In addition, Willbros Delaware receiving the Willbros USA common stock in the Internal Spin-Off would be treated as receiving a taxable dividend in an amount equal to the fair market value of the Willbros USA common stock received to the extent of Willbros Panama’s current and accumulated earnings and profits (as increased to reflect any current income, including any gain, recognized by Willbros Panama on the taxable spin-off). Any amount that exceeded Willbros Panama’s earnings and profits would be treated first as non-taxable return of capital to the extent of Willbros Delaware’s tax basis in its Willbros Panama common stock with any remaining amounts being taxed as capital gain to Willbros Delaware. (Willbros Panama owns 60% of the outstanding stock of Willbros USA and all the outstanding stock of Musketeer Oil B.V., a Netherlands holding company that owns the other 40% of the outstanding stock of Willbros USA. Musketeer Oil B.V. is a disregarded entity for United States federal income tax purposes. Therefore, the foregoing discussion reflects the fact that the Internal Spin-Off will be treated for such tax purposes as the distribution by Willbros Panama to Willbros Delaware of all the outstanding stock of Willbros USA.)
 
Information Reporting
 
You may be required to file with your U.S. federal income tax return for the taxable year in which the Merger occurs a statement setting forth certain facts relating to the Merger, including your tax basis in the shares of Willbros Panama common stock exchanged in the Merger and the number of shares of Willbros Delaware common stock received by you in the Reorganization. You must also keep a permanent record of facts relating to the exchange of your shares of Willbros Panama common stock into shares of Willbros Delaware common stock.
 
THE FOREGOING SETS FORTH THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER AND THE INTERNAL SPIN-OFF AND RELATED TRANSACTIONS UNDER CURRENT LAW. THIS DISCUSSION DOES NOT ADDRESS TAX CONSEQUENCES THAT MAY VARY WITH, OR ARE CONTINGENT ON, INDIVIDUAL CIRCUMSTANCES. MOREOVER, IT DOES NOT ADDRESS ANY NON-INCOME TAX OR ANY FOREIGN, STATE OR LOCAL TAX CONSEQUENCES OF THE MERGER OR INTERNAL SPIN-OFF. YOU ARE ENCOURAGED TO CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR CONSEQUENCES OF THE MERGER AND INTERNAL SPIN-OFF, INCLUDING THE APPLICATION OF STATE, LOCAL AND FOREIGN TAX LAWS, AND AS TO POSSIBLE PROSPECTIVE OR RETROACTIVE CHANGES IN TAX LAW THAT MAY AFFECT THE TAX CONSEQUENCES DESCRIBED ABOVE.

Ownership and Disposition of the Willbros Delaware Common Stock
 
As a result of the Reorganization, your ownership and disposition of the Willbros Delaware common stock will result in U.S. federal income tax consequences that may be different from the U.S. federal income tax consequences of holding Willbros Panama common stock. The following is a summary of certain U.S. federal income tax consequences relevant to the ownership and disposition of the Willbros Delaware common stock. This summary addresses only those of you who hold your shares of Willbros Delaware common stock as capital assets within the meaning of Section 1221 of the Code. This summary does not purport to deal with all aspects of U.S. federal income taxation that may be relevant to you in light of your particular circumstances. Further, this summary does not address holders of Willbros Delaware common stock who are subject to special treatment under U.S. federal income tax laws, such as:
 
  •  tax-exempt organizations;
 
  •  S corporations and other pass-through entities and owners thereof;
 
  •  entities taxable as partnerships for U.S. federal income tax purposes and owners thereof;
 
  •  insurance companies and other financial institutions;
 
  •  mutual funds;
 
  •  dealers in stocks and securities;
 
  •  traders or investors in our common stock who elect the mark-to-market method of accounting for such stock;
 
  •  stockholders who received our common stock from the exercise of employee stock options or otherwise as compensation;
 
  •  stockholders who hold our common stock in a tax-qualified retirement plan, individual retirement account or other qualified savings account;
 
  •  stockholders who hold their shares of our common stock as part of a hedge, straddle, or a constructive sale or conversion transaction or other risk reduction or integrated investment transaction; and
 
  •  a stockholder who actually or constructively owns more than 5% of Willbros Delaware common stock.
 
U.S. Holder
 
As used herein, the term “U.S. holder” means a beneficial owner of the Willbros Delaware common stock (i) a citizen or resident of the United States, (ii) a corporation, or an entity treated as a corporation, formed under the laws of the United States or any state thereof (including the District of Columbia), (iii) an estate, the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) in general, a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more “United States persons” have the authority to control all substantial decisions of the trust.
 
Distributions paid to a U.S. holder with respect to the Willbros Delaware common stock will be taxable as dividend income when paid to the extent of our current and accumulated earnings and profits as determined for U.S. federal income tax purposes. To the extent that the amount of a distribution with respect to the Willbros Delaware common stock exceeds our current and accumulated earnings and profits, such distribution will be treated first as a tax-free return of capital to the extent of the U.S. holder’s adjusted tax basis in such Willbros Delaware common stock, and thereafter as capital gain.
 
Subject to certain exceptions for short-term and hedged positions, distributions constituting dividend income received by an individual U.S. holder in respect of the Willbros Delaware common stock before January 1, 2011 will generally represent “qualified dividend income,” which will be subject to taxation at a maximum rate of 15% (or a lower rate for individuals in certain tax brackets). In addition, subject to similar exceptions for short-term and hedged positions, distributions on the Willbros Delaware common stock constituting dividend income paid to holders that are U.S. corporations will generally qualify for the 70%

Table of Contents

dividends received deduction. A U.S. holder is urged to consult its own tax advisers regarding the availability of the reduced dividend tax rate and the dividends received deduction in the light of its particular circumstances.
 
A U.S. holder will generally recognize capital gain or loss on a sale or exchange of the Willbros Delaware common stock equal to the difference between the amount realized upon the sale or exchange and such U.S. holder’s adjusted tax basis in the shares sold or exchanged. Such capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period for the shares sold or exchanged is more than one year. For non-corporate U.S. holders, including individuals, net long-term capital gains generally are taxed at a lower rate than ordinary income (generally 15% for most long-term gains recognized in taxable years beginning on or before December 31, 2010). The deductibility of capital losses may be subject to limitation.
 
Certain U.S. holders may be subject to backup withholding with respect to the payment of dividends on the Willbros Delaware common stock and to certain payments of proceeds on the sale or redemption of the Willbros Delaware common stock unless such U.S. holders provide proof of an applicable exemption or a correct taxpayer identification number, and otherwise comply with applicable requirements of the backup withholding rules.
 
Any amount withheld under the backup withholding rules from a payment to a U.S. holder is allowable as a credit against such holder’s U.S. federal income tax, which may entitle the U.S. holder to a refund, provided that the U.S. holder provides the required information to the Internal Revenue Service. Moreover, certain penalties may be imposed by the Internal Revenue Service on a U.S. holder who is required to furnish information but does not do so in the proper manner.
 
Information returns will generally be filed with the Internal Revenue Service in connection with the payment of dividends on the Willbros Delaware common stock to noncorporate U.S. holders and certain payments of proceeds to noncorporate U.S. holders on the sale or redemption of the Willbros Delaware common stock.
 
Non-U.S. Holders
 
As used herein, the term “non-U.S. holder” means a beneficial owner of the Willbros Delaware common stock that is not a U.S. holder (which term is defined under “Material U.S. Federal Income Tax Consequences — Ownership and Disposition of the Willbros Delaware Common Stock — U.S. Holder” above).
 
Generally, dividends paid to a non-U.S. holder with respect to the Willbros Delaware common stock will be subject to U.S. federal income and withholding tax at a 30% rate, or such lower rate as may be specified by an applicable income tax treaty (provided the non-U.S. holder furnishes the payor with a properly completed applicable tax form certifying that such non-U.S. holder is eligible for treaty benefits), unless the dividends are effectively connected with a trade or business carried on by the non-U.S. holder within the United States (and the non-U.S. holder provides the payor with a properly completed Internal Revenue Service Form W-8ECI). Dividends that are effectively connected with such trade or business (and, if a tax treaty applies, are attributable to a U.S. permanent establishment maintained by the non-U.S. holder) will generally be subject to U.S. federal income tax on a net basis at applicable individual or corporate rates and, in the case of a non-U.S. holder which is a corporation, may be subject to a “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.
 
A non-U.S. holder eligible for a reduced rate of U.S. withholding tax pursuant to an applicable income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the Internal Revenue Service.
 
Presently, any dividends from Willbros Panama to a non-U.S. holder generally would not be subject to U.S. federal income tax in the hands of a non-U.S. holder.

Table of Contents

A non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on gain realized on the sale, exchange or redemption of the Willbros Delaware common stock so long as:
 
  •  the gain is not effectively connected with a U.S. trade or business of the holder (or if a tax treaty applies, the gain is not attributable to a U.S. permanent establishment maintained by such non-U.S. holder); and
 
  •  in the case of a nonresident alien individual, such holder is not present in the United States for 183 or more days in the taxable year of the sale or disposition (in which case the gain may be subject to tax if certain other conditions are met).
 
Payment of dividends and the tax withheld with respect thereto are subject to information reporting requirements. These information reporting requirements apply regardless of whether withholding was reduced or eliminated by an applicable income tax treaty, or withholding was not required because the dividends were effectively connected with a trade or business in the United States conducted by the non-U.S. holder. Copies of the information returns reporting such dividends and withholding may also be made available by the Internal Revenue Service under the provisions of an applicable income tax treaty or agreement to the tax authorities in the country in which the non-U.S. holder resides.
 
U.S. backup withholding will generally apply on payment of dividends to a non-U.S. holder unless such non-U.S. holder furnishes to the payor a properly completed Internal Revenue Service Form W-8BEN (or other applicable form) certifying as to its non-U.S. status, or such non-U.S. holder otherwise establishes an exemption.
 
Payment by a U.S. office of a broker of the proceeds of a sale of the Willbros Delaware common stock is subject to both backup withholding and information reporting unless the non-U.S. holder, or beneficial owner thereof, as applicable, certifies that it is a non-U.S. holder on Internal Revenue Service Form W-8BEN (or other applicable form), or otherwise establishes an exemption.
 
U.S. Federal Income Taxation of Willbros Delaware and its Subsidiaries After the Reorganization
 
Willbros Delaware and our U.S. subsidiaries will be subject to U.S. federal income taxation on their worldwide income regardless of its source, subject to reduction by allowable foreign tax credits. As a result of the proposed Reorganization, Willbros Delaware will become the common parent of the group of U.S. subsidiaries filing U.S. consolidated federal income tax returns.
 
After the Reorganization, Willbros Panama will become a holding company of our non-U.S. subsidiaries. Operating income of a non-U.S. corporation generally is not subject to direct U.S. federal income taxation if such income is not “effectively connected” with the conduct of a trade or business in the United States. Willbros Panama and our non-U.S. subsidiaries will become controlled foreign corporations as a result of the Reorganization, with the result that certain types of income earned by them could be required to be included in the income of Willbros Delaware prior to such income being remitted to Willbros Delaware. Generally, those types of income include dividends, interest and certain operating income earned with the assistance of related parties. Willbros Delaware intends to minimize those types of income where feasible.
 
PANAMANIAN TAX
 
The following discussion of Panamanian tax matters is based upon the tax laws of Panama and regulations thereunder in effect as of the date of this proxy statement/prospectus, and is subject to any subsequent change in Panamanian laws and regulations which may come into effect after such date. The material Panamanian tax consequences of the merger to us and an owner of Willbros Panama common stock are as follows.
 
General
 
Panama’s income tax is exclusively territorial. Only income actually derived from sources within Panama is subject to taxation. Income derived by Panama corporations, foreign corporations or individuals from off-


39


Table of Contents

shore operations is not taxable. The territorial principle of taxation has been in force throughout the history of the country and is supported by legislation, administrative regulations and court decisions. Willbros Panama has not been in the past and does not in the future expect to be subject to income taxes in Panama because all of its income has arisen from activities conducted entirely outside of Panama. This is the case even though Willbros Panama maintains its registered office in Panama.
 
Taxation of the Merger and Internal Spin-Off
 
A holder of Willbros Panama common stock will not be subject to Panamanian taxes as a result of the receipt of shares of Willbros Delaware common stock in exchange for such holder’s shares of Willbros Panama common stock in the Merger. Neither Willbros Delaware nor Willbros Panama will be subject to Panamanian taxes with respect to the Merger. With respect to the Internal Spin-off, Willbros Delaware and Willbros Panama will also not be subject to Panamanian taxes for the same aforementioned reasons.
 
THE NETHERLANDS TAX
 
The following discussion of certain material Dutch corporate income tax consequences with respect to the Internal Spin-Off applicable to us only addresses the Netherlands tax legislation, as in effect and in force at the date of this proxy statement/prospectus, as interpreted in published case law, without prejudice to any amendments introduced at a later date and implemented with or without retroactive effect.
 
Willbros Panama holds 40% of the outstanding common stock of Willbros USA through Musketeer Oil B.V., a company incorporated under the laws of the Netherlands. In the Internal Spin-Off, Willbros Panama will distribute all of the outstanding common stock of Musketeer Oil B.V. to Willbros Delaware.
 
No Dutch corporate income tax will be due by Willbros Delaware in respect of the Internal Spin-Off. Furthermore, no Dutch corporate income tax will be due by Willbros Panama in respect of the Internal Spin-Off, assuming that the shares in Musketeer Oil B.V. do not increase in value during the period between the time of acquisition by Willbros Panama of all outstanding common stock of Musketeer Oil B.V., November 7, 2008, and the time of the Internal Spin-Off. Even if the shares in Musketeer Oil B.V. increased in value during such period, and, consequently, Willbros Panama realized a capital gain on its shareholding in Musketeer Oil B.V. in respect of the Internal Spin-Off, such capital gain should not be subject to Dutch corporate income tax, based on the fact that Willbros Panama has always been the listed parent company of the group (until the Merger immediately prior to the Internal Spin-Off) and, through its CEO and management board has an active involvement in the day-to-day and strategic management of the operating subsidiaries of Willbros Panama that are held through Musketeer Oil B.V.

(a) Exchange Agent.  As soon as reasonably practicable, Willbros Delaware shall designate a bank or trust company reasonably acceptable to Willbros Panama (the “Exchange Agent”) for the purpose of exchanging certificates representing shares of Willbros Delaware Common Shares (the “Delaware Certificates”) upon surrender of certificates representing shares of Willbros Panama Common Stock (the “Panama Certificates”). Not later than the Effective Time, Willbros Delaware will cause to be deposited with the Exchange Agent, for the benefit of the holders of shares of Willbros Panama Common Stock, certificates representing Willbros Delaware Common Shares to be provided in exchange for Willbros Panama Common Stock upon consummation of the Merger as set forth in Section 3.01 (the “Exchange Fund”).
 
(b) Exchange Procedure.  As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a Panama Certificate(s) that immediately prior to the Effective Time represented shares of Willbros Panama Common Stock whose shares were converted into and became the right to receive Willbros Delaware Common Shares pursuant to Section 3.01, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Panama Certificates shall pass, only upon delivery of the Panama Certificates to the Exchange Agent and shall be in such form and have such other provisions as Willbros Delaware may reasonably specify) and (ii) instructions for use in effecting the surrender of the Panama Certificates in exchange for Delaware Certificates. Upon surrender of a Panama Certificate for cancellation and exchange to the Exchange Agent, together with such letter of transmittal, properly completed and duly executed, and such other documents as may be reasonably required by the Exchange Agent, the holder of such Panama Certificate shall be entitled to receive in exchange therefor a Delaware Certificate or Delaware Certificates representing the number of Willbros Delaware Common Shares which such holder has the right to receive pursuant to the provisions of this Article III, and the Panama Certificate so surrendered shall be canceled. In the event of a transfer of ownership of a Panama Certificate after the Effective Time, exchange may be made to a person other than the person in whose name the Panama Certificate so surrendered is registered, if such Panama Certificate shall be properly endorsed or otherwise in proper form for transfer and shall be accompanied by evidence satisfactory to the Exchange Agent that any transfer or other taxes required by reason of such exchange in the name other than that of the registered holder of such Panama Certificate or instrument either has been paid or is not payable. Until surrendered as contemplated by this Section 3.04, each Panama Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender Willbros Delaware Common Shares in accordance with Section 3.01.
 
(c) No Further Ownership Rights in Willbros Panama Common Stock.  All Willbros Delaware Common Shares issued upon the Merger, including any Delaware Certificates issued upon the surrender for exchange of Panama Certificates in accordance with the terms of this Article III, shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Willbros Panama Common Stock theretofore represented by such certificates, subject, however, to the Surviving Corporation’s obligation (if any) to pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been


A-3


Table of Contents

declared or made by Willbros Panama on such shares of Willbros Panama Common Stock in accordance with the terms of this Agreement or prior to the date of this Agreement and which remain unpaid at the Effective Time, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Willbros Panama Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Panama Certificates are presented to the Surviving Corporation or Exchange Agent they shall be canceled and exchanged as provided in this Article III, except as otherwise provided by law.
 
(d) Termination of Exchange Fund; No Liability.  At any time following the first anniversary of the Effective Time, Willbros Delaware shall be entitled to require the Exchange Agent to deliver to it any remaining portion of the Exchange Fund, and holders shall be entitled to look only to Willbros Delaware (subject to abandoned property, escheat or other similar laws) with respect to the Willbros Delaware Common Shares and any dividends or other distributions with respect thereto payable upon due surrender of their Panama Certificates, without any interest thereon. Notwithstanding the foregoing, neither Willbros Delaware nor the Exchange Agent shall be liable to any holder of a Panama Certificate for Willbros Delaware Common Shares (or dividends or distributions with respect thereto) from the Exchange Fund in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.
 
(e)  Lost, Stolen or Destroyed Certificates.  In the event any Panama Certificates shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Panama Certificate(s) to be lost, stolen or destroyed and, if required by Willbros Delaware, the posting by such person of a bond in such sum as Willbros Delaware may reasonably direct as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Panama Certificate(s), the Exchange Agent will issue the Delaware Certificates pursuant to Section 3.01(a) deliverable in respect of the shares of Willbros Panama Common Stock represented by such lost, stolen or destroyed Panama Certificates.
 
(f)  Dividends; Distributions.  No dividends or other distributions with respect to Willbros Delaware Common Shares with a record date after the Effective Time shall be paid to the holder of any unsurrendered Panama Certificate with respect to the Willbros Delaware Common Shares represented thereby, and all such dividends and other distributions, if any, shall be paid by Willbros Delaware to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Panama Certificate in accordance with this Article III. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Panama Certificate there shall be paid to the holder of a Panama Certificate representing the right to receive Willbros Delaware Common Shares issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such Willbros Delaware Common Shares and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such Willbros Delaware Common Shares. Willbros Delaware shall make available to the Exchange Agent cash for these purposes, if necessary.
 
3.05  Warrants.  Effective at the Effective Time, the outstanding warrants of Willbros Panama to acquire Willbros Panama Common Stock shall be thereafter exercisable, in accordance with their terms, for the number of Willbros Delaware Common Shares to which a holder of the shares of Willbros Panama Common Stock issuable at the time of the Merger upon the exercise of such warrants would have been entitled to receive as a result of the Merger, in accordance with this Article III, if such exercise had taken place immediately prior to the Merger.
 
3.06  Convertible Debt.  Effective at the Effective Time, the 2.75% Convertible Senior Notes due 2024 and the 6.5% Convertible Senior Notes due 2012 of Willbros Panama shall be thereafter convertible, in accordance with their terms, for the number of Willbros Delaware Common Shares to which a holder of the shares of Willbros Panama Common Stock issuable at the time of the Merger upon the conversion of such notes would have been entitled to receive as a result of the Merger, in accordance with this Article III, if such conversion had taken place immediately prior to the Merger.

3.07  Withholding Taxes.  Willbros Delaware shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the consideration otherwise payable to any person pursuant to this Article III any such amounts as are required under the U.S. Internal Revenue Code of 1986, as amended, or any applicable provision of state, local or foreign tax law; provided, however, that if such withholding may be eliminated or reduced through the delivery of any certificate or other documentation, Willbros Delaware shall provide each holder of Willbros Panama Common Stock with a reasonable opportunity to deliver such certificate or other documentation. To the extent that amounts are so withheld by Willbros Delaware, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Willbros Panama Common Stock in respect of which such deduction and withholding was made by Willbros Delaware.
 
3.08  Willbros Panama Distributions.  Notwithstanding any other provision of this Agreement to the contrary, any payments on account of any dividends or other distributions made with respect to the Willbros Panama Common Stock, and any Merger related payments made in respect of dissenters’ rights or similar appraisal rights, if any, shall be made by the Surviving Corporation.
 
3.09  Cancellation of Shares.  All Willbros Delaware Common Shares owned by Willbros Panama immediately prior to the Effective Time shall be canceled at the Effective Time.

When a quorum is present at any meeting, in all matters other than the election of directors, the affirmative vote of the holders of the majority of the stock having voting power present in person, by remote communication, if applicable, or represented by proxy and entitled to vote shall be the act of the stockholders, except where a different vote is expressly required by law, applicable stock exchange rules, the certificate of incorporation or these bylaws, in which case such express provision shall govern and control.

The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation or, with respect to any criminal third party proceeding, had reasonable cause to believe that such conduct was unlawful.
 
Section 6.02.  Indemnification in Corporate Proceedings.  The corporation shall indemnify any person who was or is a party or is threatened to be made a party to any “corporate proceeding” (which shall mean, for purposes of this Article VI, any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor) by reason of the fact that such person is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including without limitation attorneys’ fees, actually and reasonably incurred by such person in connection with the defense or settlement of a corporate proceeding if the person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the court in which the corporate proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.
 
Section 6.03.  Mandatory Indemnification.  To the extent that a present or former director or officer of the corporation has been successful on the merits or otherwise in defense of any third party or corporate proceeding referred to in Section 6.01 or 6.02 above or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses, including without limitation attorneys’ fees, actually and reasonably incurred by such person in connection therewith.
 
Section 6.04.  Determination of Entitlement to Indemnification.  Any indemnification under Section 6.01, 6.02 or 6.03 of this Article VI (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of a present or former director or officer of the corporation is proper in the circumstances because such person has met the applicable standard of conduct set forth in Section 6.01, 6.02 or 6.03 of this Article VI. This determination shall be made, with respect to a person who is a director or officer at the time of the determination:
 
(a) By a majority vote of the directors who are not parties to the third party or corporate proceeding, even though less than a quorum;
 
(b) By a committee of directors designated by a majority vote of directors, even though less than a quorum;
 
(c) If there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion; or

Section 6.05.  Burden of Proof.  In the event a claim for indemnification by any person who was or is a party or is threatened to be made a party to any third party or corporate proceeding is denied by the corporation (except for a claim by a person described in Section 6.08 hereof), the corporation shall, in any subsequent legal proceedings relating to such denial, have the burden of proving that indemnification was not required under Section 6.01, 6.02 or 6.03 of this Article VI, without regard to Section 6.04 hereof, or under any other agreement or undertaking between the corporation and such person, or was not permitted under applicable law.
 
Section 6.06.  Advancing Expenses.  Expenses (including, without limitation, attorneys’ fees) incurred by a director or officer or former director or officer in defending a third party or corporate proceeding shall be paid by the corporation in advance of the final disposition of such third party or corporate proceeding upon receipt of an undertaking by or on behalf of the director or officer or former director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in this Article VI.

Section 6.11.  Insurance.  The corporation shall have the power to, but shall not be obligated to, purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under the provisions of this Article VI.
 
Section 6.12.  Rights Continue.  The indemnification and advancement of expenses provided by or granted pursuant to this Article VI, unless otherwise provided when authorized or ratified, shall continue as to a person who has ceased to be a director, officer, employee or agent of the corporation, or a person serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, and shall inure to the benefit of the heirs, executors and administrators of such a person.
