Item 2.   Changes in Securities
<PAGE>
 
  In July 1992 the Company sold $50.0 million aggregate principal amount of its
8.95% Senior Notes Due June 30, 1999 (the "Senior Notes") to a group of ten
institutional investors pursuant to a Note Agreement dated as of July 1, 1992
(as amended, the "Note Agreement"). The principal of the Senior Notes is payable
in five equal annual installments of $10.0 million, the first of which was made
on June 30, 1995.

  The Note Agreement prohibits any "Restricted Payment" subsequent to July 17,
1992 unless after giving effect thereto, (i) the aggregate amount of all
Restricted Payments subsequent to such date would not exceed $5,000,000 plus the
cumulative sum of 50% of the Company's consolidated net income (or minus 100% in
the case of a deficit) subsequent to March 31, 1992 and (ii) the Company could
incur at least $1.00 of additional indebtedness under the Note Agreement
covenant limiting indebtedness. The term "Restricted Payment" includes (a) any
dividend (other than dividends payable in shares of capital stock) or other
distributions on any shares of capital stock of the Company; (b) any purchase,
redemption or other acquisition of any shares of the capital stock of the
Company or any rights or options to purchase or acquire such shares; and (c) any
"Restricted Investment", which is generally defined as any investment other than
an investment in a subsidiary of the Company or an investment in certain
designated government or rated securities. In addition, the Company may
purchase, redeem or otherwise acquire shares of its capital stock or make
Restricted Investments from the net cash proceeds of the substantially
concurrent sales of shares of capital stock or from the sale of securities
convertible into such shares upon conversion.

  On June 27, 1997 the Company entered into a seven-year unsecured revolving
credit agreement with three banks (the "Credit Agreement"). The Credit Agreement
provides for a credit facility of $65.0 million, inclusive of a $20.0 million
letter of credit sub-facility. The maximum available under the Credit Agreement
is reduced in equal quarterly amounts over the last four years of the Credit
Agreement.

  The Credit Agreement prohibits any "Restricted Junior Payment" unless (1) at
the time thereof no default exists under the Credit Agreement or will be caused
thereby and (2) the cumulative amount of all Restricted Junior Payments
subsequent to June 27, 1997, would not exceed the sum of $5,000,000 plus 25% of
the Company's consolidated net income arising after June 30, 1997. "Restricted
Junior Payment" is generally defined as (1) any dividend or other distribution
on any class of the Company's capital stock, except a dividend payable solely in
shares of that class; (2) any redemption, purchase or other acquisition for
value of any shares of any class of the capital stock of the Company; (3) any
payment made to retire or obtain the surrender of any outstanding warrants,
options or similar rights to acquire any shares of any class of the capital
stock of the Company; and (4) any payment on the Senior Notes other than
regularly scheduled payments of principal and interest thereon.

Varco International, Inc.

1997 Third Quarter Report
Varco
<PAGE>
 
To Our Shareholders

Varco's third quarter results reflect record Revenues, Net Income and order
bookings, as the overall market for oilfield services and equipment continues to
strengthen, and those factors especially favorable to Varco remain positive.

As discussed in our recent reports to you, oil company exploration and
production spending has been accelerating, as has the portion of that spending
directed to the offshore areas of the world.  The resulting demand for offshore
drilling rigs has led to an overall worldwide utilization rate in excess of 95
per cent, with the utilization of selected categories of rigs effectively 100
per cent.  In response, new rigs are being constructed and rigs which had been
converted to alternate uses are being reconverted to drilling rigs.

Since a typical offshore rig, particularly one capable of drilling in deep water
and hostile environments,  requires a significant amount of equipment of the
type supplied by Varco, these trends have created a sharp increase in demand for
our products.  With rig owners generally seeking to build rigs which offer
greater capabilities and improved productivity over older designs, the newer
technology equipment which we have developed in recent years continues to gain
acceptance, thereby increasing the total dollar value of products which we
provide to such a rig.

Reflecting the stronger market, third quarter Revenues reached $140.4 million
and Net Income was $13.4 million, $.41 per share, each representing all-time
records for Varco.  By comparison, Net Income was $7.2 million, $.22 per share,
on Revenues of $98.1 million for the third quarter of 1996.  Incoming orders for
the most recent three months totaled $266.5 million, also the highest quarterly
total in the Company's history, lifting backlog at quarter-end to $395.6
million.

For the twelve months ended September 30, 1997 incoming orders totaled $743
million, exceeding revenues by approximately 51 per cent.  At that level,
customer demand is outpacing our ability to deliver; consequently, we have begun
taking steps to increase manufacturing capacity.  Our initial goal is to achieve
manufacturing and related capacity approximating $750 million in annualized
revenue by mid-1998.

It is our view that the market conditions which exist today are based upon
solid, sustainable economics throughout our industry.  We also believe that the
strategic acquisitions we have made, coupled with our continued emphasis on
product development, have strongly positioned Varco to benefit from, and
contribute to, the current industry environment.  We are committed to leveraging
that position to achieve a rate of growth which exceeds that of the overall
industry, and to generating superior rates of return for our shareholders.

At its November meeting, the Board of Directors declared a two-for-one split of
the Common Stock, payable on December 4 to shareholders of record on November
20.  Additionally, the Board adopted a Shareholder Rights Plan.  While this
action in not in response to any specific takeover threat, the Board feels it
prudent to take steps to protect Varco's shareholders from any unfair or
coercive takeover attempt.

We appreciate the continued support of our shareholders, customers, employees
and friends.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL 
CONDITION AND RESULTS OF OPERATIONS

GENERAL INDUSTRY CONDITIONS
- ---------------------------

     Worldwide drilling activity, as measured by the average number of active
drilling rigs, increased approximately 17% in the third quarter of 1997 to an
average of approximately 2,197 from an average of approximately 1,878 during the
same period in 1996.  North American drilling activity increased approximately
29% to an average of approximately 1,388 rigs and international drilling
activity increased to an average of approximately 809 rigs as compared to 801 in
the third quarter of 1996.

     Offshore drilling activity continued its year-over-year strength, as
reflected by an increase in rig utilization (mobile offshore rigs under contract
as a percent of available rigs).  For the third quarter of 1997, mobile offshore
rig utilization averaged 95% as compared to 91% in the third quarter of 1996.
The higher utilization was accompanied by increasing day rates and longer
contract periods, particularly among the "premium" offshore rigs.

     The increase in drilling activity, particularly the increase in offshore
rig utilization, has led to higher day rates and improved profits and cash flow
for the Company's major customers, the offshore drilling contractors.  This has
led to the construction of new offshore drilling rigs.  In September of 1997
there were approximately 41 new offshore rigs under construction as compared to
11 in September of 1996.

     Order bookings more than doubled in the third quarter of 1997 as compared
to the third quarter of 1996 and increased $264.1 million, 84%, in the first
nine months of 1997 as compared to the same period of 1996.  These increases are
primarily due to orders associated with the upgrading and construction of
offshore drilling rigs, particularly floating rigs that are capable of drilling
in water depths exceeding 3,000 feet.  Each such rig creates significant
potential for the high dollar value products provided by the Shaffer and
Drilling Systems Divisions as well as the products of the other Divisions.  In
addition, the incoming order rate was favorably impacted by the overall 17%
increase in worldwide drilling activity discussed above.

     The Company's increased revenue levels in the 1997 periods as compared to
1996 are generally due to improved industry conditions as discussed above.
Particularly significant has been the impact on all Divisions of the upgrading,
conversion and new construction of floating offshore rigs.  Most of the 1997
revenue increases are due to the increase in the offshore construction market.

     At September 30, 1997 the Company's backlog of unshipped orders was
approximately $395.6 million as compared to $186.9 million at December 31, 1996.
Orders for new rigs and major upgrades generally include the Company's longer
lead-time products, nine to twelve months. As a result, the Company's backlog
has more than doubled during the last nine months to the highest level in the
Company's history. The Company expects that most of the backlog will ship by
December 31, 1998. In accordance with industry practice, orders and commitments
generally are cancelable by customers at any time.

     Gross margins (net sales and rental income less costs of sales and rental
income) as a percentage of net sales and rental income improved year-over-year.
For the third quarter of 1997 gross margins were 37.1%, compared to 33.7% for
the same period in 1996 and they were 35.4% and 34.0% in the first nine months
of 1997 and 1996, respectively.  Third quarter 1997 gross margins were favorably
impacted by improved selling prices, the impact of the strong United States
dollar on foreign manufacturing costs  and on lower per unit manufacturing
costs.  Improved selling prices accounted for approximately two-thirds of the
increase while the impact of the dollar and lower per unit manufacturing costs
accounted for the remaining improvement. The higher 1997 nine-month margins
reflect the impact of the third quarter improvements.

     The Company believes that new product development is a significant factor
for the future of the Company. During the first nine months of 1997 the Company
spent $14.6 million or 3.9% of revenues on new product development. This
compares to $10.6 million or 4.1% of revenues during the same period in 1996.
<PAGE>
 
     The increase in selling, general and administrative expenses compared to
1996 is primarily a result of activity related to the increased revenues.  As a
percent of revenues, selling, general and administrative expenses are down year-
to-year.  For the first nine months of 1997 this percent was 17.5% and it was
17.7% for the third quarter of 1997.  As a percent of revenues, selling, general
and administrative expenses were 19.7% and 18.1% for the first nine months and
third quarter of 1996, respectively.

     Overall Company employment at September 30, 1997 was 2,594 (including 369
temporary employees) which compares to 1,843 (including 230  temporary
employees) a year ago. This increase is primarily due to an increase in
manufacturing employees.

     The effective tax rate for the third quarter of 1997 was 35.6% as compared
to 36.2% for the third quarter of 1996.  The lower tax rate is due to a lower
effective foreign tax rate in the third quarter of 1997 as compared to 1996.


LIQUIDITY AND CAPITAL RESOURCES
- --------------------------------------------------------------------------------

     September 30, 1997 cash and cash equivalents were $52.6 million as compared
to the December 31, 1996 balance of $5.8 million.  This increase is due to the
receipt of $67.2 million in customer deposits on equipment orders. These
deposits will be used to partially fund the working capital requirements of
these orders.

     In July 1992 the Company sold $50.0 million aggregate principal amount of
its 8.95% Senior Notes Due June 30, 1999 (the "Senior Notes") to a group of ten
institutional investors pursuant to a Note Agreement dated as of July 1, 1992
(the "Note Agreement").  The $20.0 million principal balance of the Senior Notes
is payable in two equal installments on June 30, 1998 and June 30, 1999.

     On June 27, 1997 the Company entered into a seven-year unsecured revolving
credit agreement with three banks (the "Credit Agreement"). The Credit Agreement
provides for a credit facility of $65.0 million, inclusive of a $20.0 million
letter of credit sub-facility. The maximum available under the Credit Agreement
is reduced in equal quarterly amounts over the last four years of the Credit
Agreement. Proceeds from the initial advances were used to payoff a previous
credit agreement with Citicorp USA, Inc. and Citibank, N.A and to make the June
30, 1997 principal and interest payment on the Senior Notes. At September 30,
1997 there were $20.0 million in advances outstanding and $11.2 million in
letters of credit outstanding under this facility.

     Both the Note Agreement and the Credit Agreement restrict the payment of
dividends (other than dividends payable solely in shares of Common Stock) on,
and repurchases of, Common Stock.  Under the terms of the Credit Agreement,
which is generally the more restrictive of these, the amount available for the
payment of dividends on, and repurchases of, Common Stock is limited to $5
million plus 25% of the Company's consolidated net income arising after June 30,
1997, computed on a cumulative basis.

     On November 6, 1997 the Board of Directors of the Company declared a two-
for-one stock split of its Common Stock, payable on December 4, 1997 to
shareholders of record at the close of business on November 20, 1997.

     At September 30, 1997 the Company's working capital was $147.6 million as
compared to $120.2 million at December 31, 1996 and its current ratio was 1.8 to
1.0 as compared to 2.4 to 1.0 at December 31, 1996. The increase in working
capital is primarily due to increases in inventory and receivables during the
first nine months of 1997.  The decline in the current ratio results from the
increase in customer deposits.  Long-term debt as a percent of total
capitalization was 11% at September 30, 1997 as compared to 10% at December 31,
1996.

     The Company's capital expenditures during the first nine months of 1997
were $20.1 million as compared to $7.3 million for the first nine months of
1996.  The Company currently plans to increase its rate of capital expenditures
and the Company estimates that capital expenditures will be in excess of $50.0
million over the next fifteen months. The Company believes its revolving credit
facility and its cash and cash equivalents will be sufficient to meet its
capital expenditures and operating cash needs.
