P R E S E N T A T I O N OperatorGood morning ladies and gentlemen and thank you for
standing by. Welcome to the National Oilwell Varco and Grant Prideco merger conference call. During
todays presentation, all parties will be in a listen-only mode. Following the presentation, the
conference will be open for questions. (OPERATOR INSTRUCTIONS). This conference is being recorded
today, Monday, December 17, 2007. At this time, I would like to turn the conference over to Pete
Miller, President and Chief Executive Officer of National Oilwell Varco. Please go ahead. Pete
Miller- National Oilwell Varco  CEOThanks, Mycea, and thank you for calling into the National
Oilwell Varco/Grant Prideco merger conference call. With me here today is Mike McShane, the
Chairman and CEO of Grant Prideco; Matt Fitzgerald, the Chief Financial Officer of Grant Prideco;
Philip Choyce, the General Counsel of Grant Prideco; and Clay Williams, the Chief Financial Officer
of National Oilwell Varco. This will be a reasonably brief call. What we want to do is tell you
some of the things that were looking at in the merger today. We want to give you the brief details
of the merger, and then we will take a few questions a little later. Were very excited about this
and I think its really going to the great for the shareholders of both companies. At this point
in time, I would like to turn it over to Clay Williams for a brief statement. Clay Williams-
National Oilwell Varco  CFOThanks, Pete. Before we begin this discussion of the proposed
transaction between National Oilwell Varco and Grant Prideco, I would like to point out that some
of the statements made during this call will be forward-looking statements within the meaning of
the federal securities laws. These forward-looking statements include without limitation statements
regarding the consummation of the transaction, its effect on the future earnings or other operating
results, the expected closing date and all other comments about the transaction, National Oilwell
Varco or Grant Prideco that are not a statement of historical fact. These forward-looking
statements are based on limited information as of today which is subject to change and further
subject to risks and uncertainties. Actual results may differ materially. I refer you to the 10-Q
and 10-K filings that both National Oilwell Varco and Grant Prideco have made with the SEC for a
more detailed discussion of some of the risk factors that could affect our respective businesses.
Pete? Pete Miller- National Oilwell Varco  CEOThanks, Clay. Earlier today, we announced that
National Oilwell Varco and Grant Prideco had entered into a definitive agreement for a merger. Clay
will provide the details and color on this deal a little bit later in the call. What I would like
to say at this point, Grant Prideco is the technological leader in drill pipe and bits and is an
outstanding company with wonderful employees. I would like to congratulate Mike, Matt and Philip
for creating and leading a company that is just outstanding in the business and we are very, very
excited about this becoming a part of National Oilwell Varco. I think that these guys have done a
fantastic job and I cannot overemphasize the technological advantages that they have in their
business. ReedHycalog is clearly a leader. I think things like IntelliServ pipe and the engineered
product that these guys have developed with their drill pipe is really outstanding and I think it
is truly the best products that we see in the industry today. This merger continues the strategy
of National Oilwell Varco to provide the best manufactured products and services to the upstream
oil and gas business. We think it fits very well with the things that we do today. Its additive,
it gives us more opportunities to provide for the needs of our customers. We think it creates
excep
tional shareholder value and we feel very good about the financial flexibility that we will
have once the deal is consummated. Thomson StreetEventswww.streetevents.com            Contact Us 3 ©

FINAL TRANSCRIPT Dec. 17. 2007 / 10:00AM ET, NOV  National Oilwell Varco Agrees to Acquire
Grant Prideco for Combination of Stock and CashI think another very important part of this is it
provides us with the financial strength to be able to continue to advance technology. This is
extremely important in everything that we have done, both Grant Prideco and National Oilwell Varco.
When you look at the advances that we have made on drill bits, when you look at the engineered
aspect of drill pipe, when you look at IntelliServ, when you look at drill rigs today with top
drives, iron roughnecks, pipe handling systems, electronic controls and AC, they are all
technological leaders. This merger will continue that and will enable this industry to be able to
take advantage of the technology that were able to develop because I believe of the financial
strength that well have. Well be a worldwide leader in everything that we do. The combined
companies will have over 40,000 employees, well be in over 49 countries. Well be able to support
the international and global marketplace in a manner that we have not been able to before. So as
you can tell from this, Im very excited about our opportunities. What I would like to do now is
turn it over to Mike McShane for a couple of brief comments. Michael McShane- Grant Prideco -
Chairman, CEOThanks, Pete, good morning everybody and thanks for joining us today. Its an
exciting day I think for Grant Prideco. I think this is a tremendous opportunity for our
shareholders and our employees to participate in a very strong company going forward. It is the
very logical step for Grant Prideco. This is a combination that I have thought about for years and
the only thing I didnt do was beat Pete to the punch of combining with Varco because I have always
thought that National Oilwell Varco and Grant Prideco made a great industrial fit. Ive been in
this business for close to 30 years and I think this is right at the top in terms of strategic
combinations, in terms of logic and benefits that will ultimately be realized. So were very
excited about it. We are proud to be part of National Oilwell Varco. When we look at strategic
partnerships, you look at the management teams and what they have done. While were very proud of
our track record, I certainly would point to Clay and Pete and the entire team over here in terms
of what they have accomplished with National Oilwell Varco. So we think were combining two of the
best management teams in the industry and I think theres a lot of good things that will come out
of that going forward. With that, I guess were going to turn it back over to Clay to walk through
some of the details. Clay Williams- National Oilwell Varco  CFOThanks Mike. I want to spend
just a couple of minutes covering some of the points on the transaction itself. As the press
release notes, the transaction is still subject to approval by Grant Prideco shareholders,
clearance from antitrust regulators and other customary conditions. Timing on that, we expect to
work our way through that and close late in the first quarter or perhaps early in the second
quarter of 2008. Consideration is $58 a share based on Friday closing prices. This consists of
$23.20 per share in cash and 0.4498 shares of National Oilwell Varco. So in aggregate, were
looking at about $3 billion in total cash consideration, $4.4 billion in equity consideration which
will be obtained through the issuance of approximately $57 million in National Oilwell Varco
shares. Once the transaction closes, existing Grant Prideco shareholders will own about 14% of the
combined company and existing Oilwell Varco shareholders will retain about 86%. Importantly, we
expect that this transaction will be immediately accretive to both earnings and cash flow for
National Oi
lwell Varco. This assumes cost savings of about $40 million per year which we expect to
obtain quickly after closing because most of this has to do with the fact that we wont be running
two public companies anymore, so boards of directors and auditors and D&O insurance and those sorts
of things will fall away very quickly. As part of purchase accounting, we expect to mark Grant
Pridecos assets and liabilities to market, and our preliminary estimates of that are that it will
add about $4 billion in goodwill and approximately $2 billion in identified intangibles to our
combined balance sheet. We will be finalizing these estimates through the first year after closing
pursuant to purchase accounting. This asset and liability step-up is expected to layer in $180 to
$200 million in additional annual depreciation and amortization. Of course, these are non-cash
charges which means that this transaction should be very strongly accretive to the cash flow of
National Oilwell Varco following the closing of the transaction. National Oilwell Varco will
retain our very strong balance sheet which gives us financial flexibility to continue to pursue our
strategic growth initiatives of growing through acquisitions, investments and organic growth
opportunities and investments in promising new products and technologies, like Grant Prideco
IntelliServ. National Oilwell Varco has secured bridge financing commitments from Goldman Sachs and
we expect to secure additional long-term financing in the range of $1 to $2 billion at or soon
after closing. HOU:2759779.2 Thomson StreetEventswww.streetevents.com            Contact Us 4 © 2007

FINAL TRANSCRIPT Dec. 17. 2007 / 10:00AM ET, NOV  National Oilwell Varco Agrees to Acquire
Grant Prideco for Combination of Stock and CashFollowing closing, we expect that our book net
debt to capitalization will lie in the range of about 15% following the permanent financing. We
will also preserve very strong EBITDA coverage ratios and credit metrics after closing, giving us a
great deal of financial flexibility to continue to pursue our strategy. Overall, this is a very
attractive acquisition. It adds some tremendous oil field products, franchises that the Grant
Prideco team has built to National Oilwell Varcos oilfield portfolio and we believe that the
combination further enhances the growth prospects for both organizations. With that, let me turn it
back to Pete. Pete Miller- National Oilwell Varco  CEOThanks, Clay. As I promised you, we
would be brief. It is necessary for us now to try to get back to work pretty quickly, but at this
point what we would like to do is open it up for a few questions that some of our listeners might
have. So Mycea, why dont you open it up for questions? Q U E S T I O N A N D A N S W E R
Operator(OPERATOR INSTRUCTIONS) Dan Pickering, Tudor Pickering. Dan Pickering- Tudor Pickering
- AnalystMy question I think is the same for both Pete and Mike and a little bit different for
 and the question is  why now? And Pete, I guess as I think about it relative to Grant Prideco,
great fit. It looks like Grant Pridecos drill pipe business may be soft for a little while here.
Was there a chance maybe to wait and get a better price? And then for Mike, I guess the question
is, IntelliServ has been something that you placed a pretty high value on in the past. Does this
imply something about IntelliServ, or do you feel like you got fair value for that in the $58
number? Pete Miller- National Oilwell Varco  CEOWere going to negotiate to see who goes
first, and thats going to take for (MULTIPLE SPEAKERS). You know, Dan, Mikes a tenacious
negotiator and I think that you can try to time everything down to the minute, but the fact of the
matter is that this deal makes sense. I think that we were able to kind of come to  the time is
the time. I think we just happened to get together today, we have found something that we are both
agreeable to. I think to push it out and bet that something that might go down or go up, really in
the short-term, might have been fine. But I think in the long-term what weve done today makes all
the sense in the world. And I think thats the reason you see the timing. We dont want to merge
for whats going to happen over the next quarter or two. We want to merge for whats going to
happen over the next 10 years, and we feel very good that what we have done here today is going to
make that a positive for the shareholders of this Company. Michael McShane- Grant Prideco -
Chairman, CEODan, I would echo the same comments. You have to look at this  youll note, were
taking 60% equity in this deal. This is not about the short-term, this is about building a company
that is going to be a significant player in this industry, it already is, and even stronger now on
a long-term basis. So I think that, yes, there is some head winds facing the drill pipe business in
the short-term. We all understand that. Pete and his guys are well aware of that. Theyre closely
joined at the hip in that business with us. But I think mitigating factors are the upside, with
things like IntelliServ that help on balance give Pete and Clay the comfort that the value is there
in the long haul. So I think thats about all we have to say on that topic. Dan Pickering- Tudor

FINAL TRANSCRIPT Dec. 17. 2007 / 10:00AM ET, NOV  National Oilwell Varco Agrees to Acquire
Grant Prideco for Combination of Stock and CashNext and last question for me. Pete and Clay, as
you looked at the transaction terms here, your balance sheet clearly could have withstood using
more cash. Was it a negotiating issue on the amount of stock, or was it a flexibility issue? Clay
Williams- National Oilwell Varco  CFOReally a negotiating issue. We recognize the opportunity
to lever our balance sheet a little bit more through this. We certainly have lots of room, as you
can see. Weve pressed for a little more cash and Mike and his team pressed for a little more
stock. But at the end of the day, were very pleased with where we came out. It does preserve a lot
of financial flexibility to enable us to continue to pursue our strategic objectives. So were glad
we ended up where we are. Dan Pickering- Tudor Pickering  AnalystThank you and
congratulations. OperatorBill Herbert, Simmons & Co. Bill Herbert- Simmons & Co.  Analyst
Pete, have you thought about how Grant Pridecos operations get integrated into National Oilwell
Varco and really how the business model for GRP within NOV changes? Pete Miller- National Oilwell
Varco  CEOWell, yes, Bill. One of the things that we have a lot of experience at is integration
and we clearly have put some thought into it. I think its probably too early in the game to spell
a lot of that out. We still have a lot of things that we need to do, a lot of great people we need
to determine where theyre going to be. But I think overall, I think the business model is such
that were going to be able to provide a wider array of products to our international customer
base. And I think as you take a look at the type of products that are here, we think it really does
fill up the entire cycle of what you normally see in the oil & gas business. You have early, mid
and late. We have the capital side, now were going to be adding bits to the different things that
we do in the early and mid-level. I think drill pipe is much more of an expendable today than it
has been in the past. We like that aspect of things. So I think what it really does on a business
model, it gives us probably one of the more compelling arguments of having a company in the oil
service business that can handle any part of the cycle very well. So that is kind of where we are.
And as time goes by, well tell people more about the integration process itself. Bill Herbert-
Simmons & Co.  AnalystOkay. And with regard to the $40 million in cost saves, how do we get
there? Clay Williams- National Oilwell Varco  CFOThat is predominately overhead costs, Bill
 senior management team, Board of Directors, auditors, all that sort of thing. We do believe that
there is some additional efficiencies that may be available out there to us. There may be some
additional revenue growth that we can achieve by putting Grant Prideco products through NOV
channels. But we really havent taken benefit of that and need to study that a little further. But
we believe we get there largely through overhead savings. Bill Herbert- Simmons & Co.  Analyst
Finally, you may have mentioned this, but I missed it. With regard to, Clay, your cash on the
balance sheet, which is about $1 billion how are we going to finance the cash component of this.
just for modeling purposes? HOU:2759779.2 Thomson StreetEventswww.streetevents.com            Contact

FINAL TRANSCRIPT Dec. 17. 2007 / 10:00AM ET, NOV  National Oilwell Varco Agrees to Acquire
Grant Prideco for Combination of Stock and Cash Clay Williams- National Oilwell Varco  CFO
Overall cash off of our balance sheet, some cash potentially off of Grant Pridecos balance sheet,
which as youll remember, is in the middle of a transaction to sell part of the TTS business in
cash, and then some external financing, which will be in the range of $1 to $2 billion. Bill
Herbert- Simmons & Co.  AnalystAnd with respect to quantifying the accretion, you guys
mentioned that it was accretive to both earnings and cash flow. What exactly are the numbers? Clay
Williams- National Oilwell Varco  CFOIm going to not quantify it for you, other than to say
that its fairly compelling. Bill Herbert- Simmons & Co.  AnalystWhich is based on street
numbers? Clay Williams- National Oilwell Varco  CFOWe have looked at numbers from really from
both companies. Were in the middle of our 08 budgeting processes and have run our models with
internal numbers. Bill Herbert- Simmons & Co.  AnalystExcellent. Thank you very much.
OperatorRoger Read, Natixis Bleichroeder. Roger Read- Natixis Bleichroeder  AnalystGood
morning, gentlemen, congratulations on the deal. Pete Miller- National Oilwell Varco  CEO
Thanks, Roger. Roger Read- Natixis Bleichroeder  AnalystClay, anything on breakup fees? Clay
Williams- National Oilwell Varco  CFOYes, they are pretty customary. We will be filing the
merger and sale agreement a little later today. I think were (inaudible) it right now, and it will
come out on the 8-K a little  we expect later today. HOU:2759779.2 Thomson StreetEvents

FINAL TRANSCRIPT Dec. 17. 2007 / 10:00AM ET, NOV  National Oilwell Varco Agrees to Acquire
Grant Prideco for Combination of Stock and Cash Roger Read- Natixis Bleichroeder  AnalystAnd
then the other question I had, given that for the most part these are not businesses that overlap
significantly with your own, is there anything that you would not want to keep going forward,
whether its the last of the tubular business, XL or any part of the drill bit side? Pete Miller-
National Oilwell Varco  CEONo, we think all the businesses fit quite well with what we want to
do long-term strategically, Roger. We like what they have and that is the reason were doing the
deal. Roger Read- Natixis Bleichroeder  AnalystOkay, thank you. OperatorRobin Shoemaker,
Bear Stearns. Robin Shoemaker- Bear Stearns  AnalystYes, let me add my congratulations too,
Pete. And just looking at your margins in Grant Prideco, of course in the last couple of years, it
has had very robust margins. However, Mike has been a little cautionary here recently about the
outlook for drill pipe sales in 08 and has seen a kind of declining backlog over the last four
quarters. So in any case, is the outlook any different for next year versus the kind of outlook
that Mike gave on the third quarter, that bookings for North America are still quite slow from
domestic contractors and you would expect to see perhaps a 2 to 3 million-foot decline in drill
pipe sales in 08 versus 07, in North America? Pete Miller- National Oilwell Varco  CEO
Robin, theres really not any difference. I think the things Mike talked about is really the way we
see the market today. I think weve been very open with each other about where we see the market. I
agree with you that theyve done a fantastic job on margins, but one of the things about the market
today is I think its reasonably self-correcting in a rapid fashion and I think one of the things
that Grant Prideco has shown us very well is that you are really talking about drill pipe almost
being an expendable anymore. So were very comfortable that, even though you might have some
headwinds, as you look out into 09 and other time frames, the business is going to be very good.
We believe its going to be a very compelling business over a two or three-year period. Michael
McShane- Grant Prideco  Chairman, CEOBear in mind  Robin, this is Mike  that while we have
talked about the softening environment here in the near-term in North America, were also quick to
point out the continued strength internationally in China, and importantly the demand associated
with new offshore rigs coming into the market, which pushes more and more towards the premium end
of the product line. So theres a large mitigating factor here in the near-term that I think Pete
and Clay should be able to get comfort with. Robin Shoemaker- Bear Stearns  AnalystYes,
right. Thats all for me. Thank you. OperatorHOU:2759779.2 Thomson StreetEvents

FINAL TRANSCRIPT Dec. 17. 2007 / 10:00AM ET, NOV  National Oilwell Varco Agrees to Acquire
Grant Prideco for Combination of Stock and CashOle Slorer, Morgan Stanley. Ole Slorer- Morgan
Stanley  AnalystThanks for letting me in on the call here, congratulations on getting this deal
done. Pete, were there any particular aspects of Grant Pridecos business that you find more or
less strategic in terms of deciding to do this acquisition? Pete Miller- National Oilwell Varco -
CEOOh, no. I think, Ole, as you look at the Company, I think all major elements are very
strategic to us. I have always been a guy that has been on record as liking drill bits, and I think
that ReedHycalog is probably in my mind the technological leader on drill bits. I wont say I like
it any more than drill pipe, but I do believe it really is I think a very compelling product that
they have. I think it really has an opportunity. When you look at the fixed cutter bits today, you
think about the efficiencies that weve created in the drilling business. Quite frankly, fixed
cutter bits is really number one in being able to create those efficiencies. I can show you bit
records from 1980 where you have 20 trips on a 10,000-foot well change in bits, and today you might
do that in about one or two bits. So I think thats really kind of a neat product to add, or a neat
arrow to put in our quiver. But at the same time, I do believe that when you look at the engineered
side of a lot of this drill pipe today, whether youre talking about high torque, all of the
different things that are associated with it, I think its very compelling too. So I just think the
entire company is a great fit, Ole. Ole Slorer- Morgan Stanley  AnalystThats good. So as a
follow-up question, I think there is a noncompete between Grant Prideco and Tenaris on drill and
that a change of control in Grant Prideco will remove that noncompete. Have you considered that?
Michael McShane- Grant Prideco  Chairman, CEOI think the, as you refer to, noncompete, is
really embedded in a long-standing I believe very strong business relationship between Grant
Prideco and Tenaris in how we go about in a cooperative manner producing drill pipe in Mexico. I
dont think that this combination is going to impact their position on that whatsoever. Ole Slorer
- Morgan Stanley  AnalystOkay, thank you very much. OperatorThat concludes our
question-and-answer session. At this time, I will turn the call back over to Mr. Miller for any
closing remarks. Pete Miller- National Oilwell Varco  CEOThanks, Mycea, and I appreciate
everybody calling and our listening today. As time goes by, well keep you posted on the progress
that were making. But let me just reiterate our excitement about this merger and the fact that
were going to make this very successful as we go to the future. Thank you for calling in today.
OperatorThank you, sir. Ladies and gentlemen, this concludes the National Oilwell Varco and
Grant Prideco merger conference call. If you would like to listen to a replay of todays
