Now I will turn the conference over to Mr. Mike Curran, Chairman and Chief
Executive Officer of Willbros.

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

Good morning, everyone, and thank you for joining us. It has been a little more
than three months since our last conference call, and I wanted to update you on
our progress on several fronts. We also wanted to give you an opportunity to ask
questions that may be on your mind.

As we reported in May, the Audit Committee Task Force has made its report to
management, and we continue to work diligently to complete and file the
Company's financial reports. We continue also to work very closely with our
external auditors to address all their questions. This is a very demanding,
time-consuming and costly exercise that has taken longer than we ever
anticipated.

Concurrently we have been moving forward with our reorganization of the
International and Nigeria management teams, and we are continuing to bid on and
be awarded new projects. Since our last call on May 17th, we have implemented
additional management and process changes and will update you today on the
actions we have taken on that front.

With the new management of our International group in place we have now also
extensively reviewed our existing international contracts in order to validate
our anticipated contract margins. This review has resulted in a reduction of our
contract margins on some of our international projects. We also have some
information to share with you on the status of our convertible notes and the
Company's financial position.

Following Warren's update, I will discuss the outlook with respect to new work
opportunities and our view of the prospective market for our services. Now I'd
like to turn the call over to Warren.

AUG. 29. 2005 / 9:00AM, WG - WILLBROS GROUP, INC. UPDATE CONFERENCE CALL

WARREN WILLIAMS - WILLBROS GROUP - CFO

Thanks Mike. As Mike mentioned, management was informed of the findings by the
Audit Committee Task Force in May. Since then we have advanced the review and
analysis of the supporting documentation associated with the task force
findings. The Company is working towards an anticipated September issuance of
its financial statements for 2004 and for the First and Second Quarters of 2005.
The filing of the Company's financial statement is the highest priority of all
of us, and we are working with our auditors to file our statements as soon as
possible. While management believes we are building momentum towards a September
filing, this process is not entirely within management's control since our
auditors must complete their work in order for us to reach that date. The
financial update I'm going to provide is subject to change pending management's
and our independent auditor's final review and analysis.

For the first six months of this year, the Company generated revenue of
approximately $300 million. About $110 million was in North America and
approximately $110 million [sic, correct value $190 million] in West Africa, the
Middle East and South America.

Contract margins associated with this work were approximately 15.4%. These
margins are lower than our original expectations due to the disruptions
attributable to the investigation, the reorganization of the International
management team, and the recent reassessment of existing contracts taken by the
new International management team.

Our G&A expenses through the first six months of 2005 have been approximately
12% of our current revenue levels. Approximately $6.5 million of this amount has
been third-party direct costs associated with the investigation. The indirect
costs associated with the investigation are not easily quantifiable. However,
management believes they are significant if one considers the time and energy
project personnel in the various work countries have devoted to this
investigative process.

Taxes -- because the tax regime in Nigeria distorts the effective tax rate for
our business, we felt it important to pass on to you our estimated income taxes
in Nigeria for the first six months of the year. We currently estimate our
income tax in Nigeria for this period to be approximately $8.5 million.

With regards to our notes convertible, in June Whitebox Advisers purported to
place the Company on notice of an event of default with respect to our notes
convertible -- our convertible notes. Whitebox has now agreed to withdraw its
notice subject to bondholder approval of an amendment to the indenture. This
approval requires a majority vote through a consent solicitation.

We filed an 8-K describing our agreement with Whitebox on August 23, 2005. Among
other things the indenture amendment provides that, one, note holders waive any
purported noncompliance which may have resulted from the Company's inability to
timely file its periodic reports with the SEC. The waiver period is nine months
from the date the amendment is approved. Two, the Company will extend the
initial date on which it could redeem all or any portion of the notes for two
years through March 15, 2013. Three, in the event of a fundamental change
involving a sale of the Company in which at least 10 percent of sales proceeds
were paid in cash, the Company will pay a make-whole payment to the note
holders. The make-whole payment would consist of no more than the present value
of two years of scheduled interest payments on the notes. Make-whole payments
are a type of event risk protection that has become common in the marketplace
since we issued our convertible notes. There's no current cash cost outside of
solicitation cost that will be incurred by the Company as a result of this
agreement. And finally, while the consent solicitation is pending, Whitebox has
agreed not to take any further action with respect to its purported notice of
default.

Backlog at the end of June was approximately $720 million, down slightly from
the $750 million at March 31st that we reported in May. The approximately $260
million in recently announced new work awards which carry an overall embedded
margin of approximately 20% are not included in our June 30th backlog number.
Consequently, we expect

to see an increase in backlog at the end of the third quarter. Embedded margin
in our engineering and construction projects in backlog at the end of June was
approximately 17%.

The Company's cash position at June 30, 2005 was approximately $54 million and
is now at that same level. Currently we believe that our cash position is
adequate to manage the business going forward.

Now I will turn the call back over to Mike.

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

Thanks Warren. When we talked last on May 17th, I addressed the quality of our
new operations management team in Nigeria and the expectation that their
experience and professional credentials would provide the focus and improvement
that we needed to execute our backlog and generate profits. We have completed
the reorganization of our operations in Nigeria this month. This new
International management team has thoroughly examined the projects and the work
in backlog. While we have lowered our margin expectations on some work under
contract we're taking steps that we believe will reduce costs, improve
production and potentially help us recoup some of the margin reduction. In
recent weeks we have seen greater productivity in pipe lay rates and other
measures of job progress which point to improved execution. The newly announced
international work was bid by this current management group and margins on this
new work exceed current margin levels and should contribute to returning the
Company to profitability in the future.

New contract awards in North America which were communicated in the press
release on August 25th are significant in their own right, but also are
important because they are evidence of work assignments in a market that has
been weak since 2002.

From a risk management perspective we believe that a better balance of work
between North America and our International operations is important. We are
pleased that our objective to build the backlog in North America is producing
tangible results.

And now I want to speak briefly about the quantity and quality of our prospects
for work. A concern we all had when the details of the investigation were known
was that our work opportunities might be diminished. We can now see that our
clients continue to offer us opportunities to qualify and bid for work, and our
prospect list stands at approximately $7.8 billion worldwide.

To add some detail, since our last conference call in May we have been asked to
bid by both existing and new clients, including people like Shell, Exxon Mobil,
ChevronTexaco, AGIP, PDO, and Saudi Aramco on more than $1.5 billion in new
work. From the recent announcement, you can see that we have also had awards in
excess of $260 million, some of it from these same customers. In addition to
these projects, we understand we're currently in the running for a number of
other jobs. However, we're not yet ready to categorize them as "highly
confident."

Additionally, our industry contacts are indicating a very tight supply of line
pipe in North America in 2006, as well as plans for one, possibly two, new pipe
mills to be built in the US to meet the anticipated demand for large diameter
pipe on this continent. This provides us with some additional data to support
our belief that the North American market is on the rebound.

Before we take your questions, I want to remind you that our financials are not
complete, and therefore we just cannot discuss them beyond the information we
have provided you today. We are, however, available to answer questions with
respect to new work awards, our banking relationship, general business and
markets. I know you have questions, so we will take them now.

(Operator Instructions) Neal Dingman.

NEAL DINGMAN - MS HOWELLS - ANALYST

MS Howells. Appreciate the update. Just two quick questions. You mentioned,
Warren, the higher G&A rate that's going on now attributable to the
investigation. My question is sort of centered around that, as far as how long
you can potentially see these higher costs. Is this something that you can
continue to see for this year well into '06? And then wondering when you think
you would have an idea as some of those whether you wanted to term those below
line or above line items. Any sort of penalties when those could start arising?
Thanks.

WARREN WILLIAMS - WILLBROS GROUP - CFO

Let me take the last question first with regards to the penalties. At this point
in time we have no idea. I mean, we had some contact with the Department of
Justice and the SEC, but we have no indication of where -- they are very early
in that process, so we have no idea when those might arise, if any are assessed
to us.

With regard to the G&A costs, the additional costs, we anticipate seeing those
through the balance of this year. And how -- and what levels we have in 2006 are
going to be dependent upon the ongoing investigation and the amount of support
that is required. And again, we're now focused -- our internal investigation is
over with. We're now supporting the investigation by the SEC and the Department
of Justice.

Michael Christodolou.

MICHAEL CHRISTODOLOU ANALYST

Inwood Capital. I just wanted to get a little more understanding of the embedded
margin. It looks like on the 720 of backlog that you have, you are tweaking that
down a bit to 17%, but the new wins are back at the historical 20% level. Can
you give us a little more detail as to (inaudible) further reductions may have
been and what geography and what types of projects?

WARREN WILLIAMS - WILLBROS GROUP - CFO

Again, the reduction to 17%, a fair amount of it came as a result of the
reductions on the work -- of our current work, the projects that we have in
place as the new management team is coming in and reassessed the costs
associated with completing that work on a going forward basis. So that has an
impact on the business. And the balance, the embedded margin in backlog.

With regard to the new work, as Mike said, the new work was bid by the current
management team, and we believe that work will (indiscernible) see higher
margins on it.

MICHAEL CHRISTODOLOU ANALYST

Are there any reductions in North American or South American backlog as opposed
to Nigerian backlog?

WARREN WILLIAMS - WILLBROS GROUP - CFO

AUG. 29. 2005 / 9:00AM, WG - WILLBROS GROUP, INC. UPDATE CONFERENCE CALL

None of any substance. There were maybe a few projects that had minor
reductions, but that's pretty common. Most of the reduction in backlog that
impacted the embedded margin in our backlog came in Nigeria.

MICHAEL CHRISTODOLOU ANALYST

So on a blended basis maybe the number is going to end up being 900 million plus
of backlog September 30th. What should that -- that margin will be upper teens
maybe -- 18.5, 19?

WARREN WILLIAMS - WILLBROS GROUP - CFO

I'm not sure I would push it all the way up to 19, but it should be up from
where we are. It's hard to say at this point because you don't know what's going
to be added here in the balance of this month. If we have a large project that
would come in North America, that could pull the margin back down just because
North American margins are lower than they are in the International segment. So
it's hard to say what it's going to be at the end of September, but if it would
follow this trend, yes, it would be up.

WARREN WILLIAMS - WILLBROS GROUP - CFO

I'm misstated. It is 190 million from the International segment.

STUART GOLDBERG - PSD CAPITAL - ANALYST

Okay, there you go. And that's the 15.4 contract margins on the 190?

WARREN WILLIAMS - WILLBROS GROUP - CFO

Right.

Overall?

WARREN WILLIAMS - WILLBROS GROUP - CFO

Yes, sir.

STUART GOLDBERG - PSD CAPITAL - ANALYST

Thanks for clarifying that. And then taxes, you said six months in Nigeria, 8.5
million. What will be the total tax bill for the six months?

WARREN WILLIAMS - WILLBROS GROUP - CFO

I'm going to defer on that because I'm still working through the final numbers,
but Nigeria will be the most significant component of the tax amount at the end
of the first six months.

STUART GOLDBERG - PSD CAPITAL - ANALYST

And then Mike, when you talked about a 7.8 billion worldwide prospect list, you
said you had been asked to bid by existing new clients on roughly 1.5 billion
new work, and then you made a comment in the running for other jobs, but you're
at this point not highly confident. Can I infer from that that you are highly
confident on the 1.5 billion?

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

No. Let me back up a minute. We've bid about $1.5 billion worth of work since
that last conference call. We've come up with $260 million worth of work, and we
have some other things out of that that we feel pretty good about. We know we're
going to be called in. Whether we end up with it or not, I cannot tell you. And
I know this sounds a little bit funny, but let me give you an example.

In the last month we've turned down $100 million worth of new work. In other
words, we went in, we sat down with the clients, we went through contract
negotiations, they were talking with someone else; one job was in West Africa,
one job was in the Middle East, and they said you know this is your job at $45
million in one instance. And we said you know, we're really not interested in it
at $45 million. And they said well somebody else is willing to take it at that.
And we said well, we just feel it's worth a little more money. And the same
thing in West Africa.

So we can get into a situation where we have an opportunity for job, but either
because the contract or the client wants to trade a little on the price or would
like you to match the low guy's price or contract terms, we will step back. And
so that's why I don't feel that strongly right now about some of these projects.
We could well end up with them, but to sit here and tell you today we really
know about another $200 million worth of work that we're going to get, I don't
feel good on it.

Now, when we had this conference call in May, we pretty well had things hemmed
up on a lot of this work. We were down to dotting the i's and crossing the t's
and doing that type of thing, or in many instances the client has to go back to
their partners to allow us to come up with a press release, so we had them
signed up. So we just -- we can see some other things in the works that we're
going to end up with, but we're just not willing to step out and say is it's
this amount or that amount.

Now, with respect to the 7.5 billion or 7.8 billion, what we do there is we go
through the prospects around the world by region -- by West Africa, North
Africa, the Middle East, Southeast Asia, Latin America and North America -- and
we look at projects that kind of fit our matrix. We're not talking about
something offshore working 3000 feet of water.

That's not our kind of business. We're not talking about work on Sakhalin Island
or in China; that's not our kind of business. But work that fits us, that we
know that our clients are going to come to us either on a pre-qualification or a
bid and ask us to bid. And so we use this as kind of a barometer on what we see
in work out in front of us for the next 12-24 months. And we see this barometer
increasing pretty well and with a finite number of competitors. So we see the
market picking up. And at the same time we would like to believe that as we go
down this road we're going to have some pricing power with respect not just
price but risk we absorb as well.

STUART GOLDBERG - PSD CAPITAL - ANALYST

And then Mike, just following up on that, in the last question you talked about
tight supply of line pipe in the US in '06 -- two words I really like to hear --
tight supply. Can you just give us -- expand upon that a bit?

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

Well it's, you know, sometimes these things get to be a little bit of a
self-fulfilling prophecy. When people see that price is getting tight, then they
will start making commitments earlier on and you've had some capacity taken out
of the US market with a big mill in Napa shut down this past year. So there is
less capacity in the United States than there was a few years ago. There's still
is pipe being brought in from overseas. The last big EPC project we did earlier
this year in The States, that pipe came from Italy. So it is a worldwide supply,
but we do see it tightening up because we see a substantial number of projects
and the capacity to produce that pipe is not going to be here in the US.

This is Raj from Colden Capital. I just had a quick question with Katrina and
the damage in the Gulf. Do you think there's opportunity for future work there?
And if so, I'm just wondering is that the type of work you would like to do?

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

We have various opportunities for work. That's not really our market right now.
We're working onshore in the Gulf. We have a substantial project in Louisiana
right now, as well as other places in the Southeast. You can see on the land
side of the business some big problems with -- or possible problems with river
crossings or erosion or that sort of thing where we would do work. But as far as
in the Gulf, no. We work offshore in Venezuela and we do in West Africa, but the
Gulf Coast market has been extremely competitive. We haven't really seen anybody
make any money there in the type of work we do in the last few years. So on the
US side of the Gulf we have chosen not to participate, and I think there's
plenty of capacity there to fix anything that needs to be fixed.

The second question relates to the embedded margins that got brought down. Could
you just provide me some amount of detail in terms of what did you find out and
why did you bring the margins down? They seem manageable. I'm just curious what
happened.

AUG. 29. 2005 / 9:00AM, WG - WILLBROS GROUP, INC. UPDATE CONFERENCE CALL

Well, part of what you're doing when you change things up in a project and you
put a new management team in, they are going to be probably more conservative
than the last guy. And I think you would probably be the same way if you took
over a stock portfolio. I think that's human nature with respect to the
contingencies people put in and that sort of thing.

But the other thing that we found kind of looking at it more specifically is we
have had a couple of things that we are experiencing. Number one, to attract the
kind of people that we want, the world is changing out there today. We have in
this Company historically been on a 90-14 rotation policy -- you work 90 days,
you are off 14 days. Our clients are on 28-28. So you can see there's a big
spread. And we've changed it to 60-30. That has increased our costs for direct
labor, airline tickets for rotation, that sort of thing.

We're seeing, like everyone else, a significant increase in fuel costs around
the world. And we're seeing an increase in steel prices. Some of the jobs we
have going right now were bid in late '03, early '04. If you recall, last year
we had a lot of things delayed, and so we're seeing some increases there.

Some of these things we believe we can get back; some of them we can't. But I
would say it's probably been more in the area of labor, and what we're doing to
offset that is try and use fewer Americans, fewer what we call ex-pats, and more
third-country nationals and more local people that can do these jobs.

Marty Malloy.

MARTY MALLOY - HIBERNIA SOUTHCOAST - ANALYST

Hibernia Southcoast. The first question I had was could you comment a little bit
more on the opportunities you see in North America? You had, it looked like, a
number of awards for the oilsands up in Canada. Were there more awards there?
Also, are you seeing potential bidding opportunities on larger interstate
pipelines and also LNG import facility related pipelines?

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

We are -- let me kind of start with the LNG facilities. We are -- we're seeing
some opportunities related to the LNG facilities. We just finished a project for
Trunkline earlier this year that was directly related to that. We're looking at
some other projects as well.

Those big kind of header systems that will come out of the LNG facilities will
probably not be built until 2007-2008. Some of them will probably be awarded
next year, especially those that are done on an EPC basis where the engineering
and material work has to begin to be done. But we don't see the real impact of
the LNG work until these systems are put in place, because they are not
necessarily going to go where it makes the most sense from a US pipeline grid,
but rather where there's the least environmental resistance. So once they are in
service and once they are starting to ramp up, then I think you'll see
substantial additional work.

But we are seeing opportunities on work in a lot of other areas. There's
significant gas in Western Wyoming and Western Colorado that the focus is to get
to the East Coast. You've seen some large lines announced there. Those lines
will be a year or so away, but we're doing a lot of station work to kind of beef
up the capacity on the existing lines right now.

We're also seeing a substantial amount of work in the near term in the Southern
United States with some of the new or newer master limited partnerships that are
building pipeline systems in the South. And so that's one of the areas that we
see being very active in the next year or so.

AUG. 29. 2005 / 9:00AM, WG - WILLBROS GROUP, INC. UPDATE CONFERENCE CALL

Also, we see an increasing amount of work on rehabilitation and re-qualification
of existing pipeline systems as their volumes ramp up in the grid.

And, in the oilsands, we continue to see that grow. We've not only focused on
the more traditional work we've done up there, but also in expanding into work
with new clients. Some of the work we announced recently was for Canadian
Natural Resources. So we work for Syncrude, Suncor, Albian Sands, Canadian
Natural Resources, most of the producers up there. And the focus now in addition
to this is to expand our operations into the fabrication of these module
facilities and install them in the field. So we see our market continuing to
grow up there because it is probably the most vibrant market in our industry in
North America.

MARTY MALLOY - HIBERNIA SOUTHCOAST - ANALYST

When will your capacity expansion be complete up there?

WARREN WILLIAMS - WILLBROS GROUP - CFO

The fabrication facility?

MARTY MALLOY - HIBERNIA SOUTHCOAST - ANALYST

Yes.

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

I'd say probably in the next six weeks. And we are currently bidding work. We
have some proposals in to put that in service.

MARTY MALLOY - HIBERNIA SOUTHCOAST - ANALYST

My last question. Can you give us an idea of the magnitude of the differential
between contract margins in North America and what you've seen internationally?

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

I'll let Warren speak to this. I'm not trying to dodge you here, but it really
varies because as we have discussed in the past, we do more engineering in the
US than we do internationally, and that has less of a margin. When we have EPC
work with a significant material component that will pull it down as well. But
generally what would you say, Warren?

WARREN WILLIAMS - WILLBROS GROUP - CFO

I mean, your margins in North America are going to be in the mid- to low-teens,
and in international you are going to work to try to get it in the mid-20s.

LEE CURRY - GUERRILLA CAPITAL - ANALYST

Lee Curry, Guerrilla Capital. I'd like to have you comment, please gentlemen, on
how long your current lead banking relationship has been in existence and what
you learned about your bank and your bankers and how they understand your
business in your recent negotiations with them.

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

Warren, do you want to --?

WARREN WILLIAMS - WILLBROS GROUP - CFO

Credit Lyonnais leads the syndicate and Credit Lyonnais has been with us from
the late '90s. They have -- they were here as part of the syndication when I
joined in July of 2000. They were not the agent bank at that -- the lead bank at
that point in time. They have been very supportive throughout this entire
process, as have been all of our banks within the bank group. So we have been
extremely happy with the relationship that we've had with our banking syndicate.

They do understand our business. They have worked with us as we've walked
through the issues associated with Whitebox and are in negotiations with them.
They understood our position. They supported our position in that regard. So
they just have been very supportive. We've had individual members of the banking
syndicate, at the time when we did not have the waiver and you remember there
was probably about a month and a half period of time when we did not have access
to our credit facility where one of the member banks in the facility stepped up
and provided us with letters of credit so that we could continue our bidding
process outside of the credit facility. They did that on their own.

So I would say our relationship with them and their knowledge of our business is
outstanding at this point in time.

MICHAEL CHRISTODOLOU ANALYST

My question is on the defense energy support center refueling contract that you
had, and I guess it's your third or fourth of those. And I'm just trying to
maybe get some clarification. You have cited that the Justice Department
investigation could result in the loss of US government projects, and yet this
seems to be kind of counter to that. And I'm wondering if that concern is
effectively eliminated or less of a concern in your mind given this contract
win.

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

I think it would be very presumptuous to say that anything would be less of a
concern. This is something we've been working on for a number of months, as well
as some similar type of projects. And we just -- I don't know that we are at the
point in the investigation with the regulatory agencies that they've really made
any decisions what they may or may not do, but we continue to bid and obtain
work for the other government agencies we work for.

And just a follow-up question for Warren. Warren, can you just give us a little
update -- in the May release you talked about building out some of the
accounting infrastructure. And can you also maybe give us a little color as to
where KPMG is? I presume they've just kind of been hand-in-hand with you through
this whole process.

WARREN WILLIAMS - WILLBROS GROUP - CFO

They are. And they are being supportive in this process also. In moving through
it's just a lot of information that we have to work through together.

With regards to building out the accounting infrastructure, we are making
progress there. We are in the process of getting the new software system up and
going in Nigeria so that we have greater visibility into the operational and
accounting data through the corporate office here. So everything in that area is
moving along. Obviously we would like to see it moving a little bit faster, but
there are a lot of things that are involved in that type of work that are
slowing us down.

OPERATOR

Mr. Curran, at this time there are no further questions. Please continue.

MIKE CURRAN - WILLBROS GROUP - CHAIRMAN, PRESIDENT & CEO

I really want to thank you for your interest today. And we want to confirm -- I
know sometimes you've got to be wondering about us, but we want to confirm that
despite the distractions of the investigative process, we have been actively
involved in running the business these past months. We have focused on
assembling a highly effective and high quality management team in Nigeria,
improving our management processes in that region, assessing anticipated returns
on existing contracts and building backlog of a quality nature for the future.

The market fundamentals both internationally and in North America support the
case for increased demand for our services going forward and we are adjusting
our Company and our operations to really participate in this. We look forward to
talking to you further when we file our financials. And at that time I think we
can provide you a lot more detail. Once again, I want to thank you very much and
have a good morning.
