                                    PART I

ITEM 1.  Business.

(a)  TRINOVA Corporation ("TRINOVA") is a world leader in the manufacture and
distribution of engineered components and systems for industry, sold through
its operating companies, Aeroquip Corporation ("Aeroquip") and Vickers,
Incorporated ("Vickers"), to the industrial, automotive, and aerospace
markets.

       The Board of Directors of TRINOVA has voted, subject to approval by
the shareholders of the Company, to change the name of the Company to
"Aeroquip-Vickers, Inc."  The proposal will be submitted to the shareholders
of the Company for approval at the annual meeting to be held on April 17,
1997.

       On February 20, 1997, TRINOVA announced that it plans to exit its
interior automotive plastics business, and will record a special charge in
1997 related to exiting these businesses.  The pretax charge is not to exceed
$30 million, approximately $18.5 million net of tax or 61 cents per share.  A
significant portion of this charge is related to exiting businesses in
Germany.  On March 10, 1997, TRINOVA announced that a definitive agreement has
been signed to sell facilities in Chesterfield and Port Huron, Michigan and
Chihuahua, Mexico to Key Plastics Inc.  The three facilities had sales in 1996
of approximately $30 million.  Buyers are being sought for the other
facilities which had combined 1996 sales volume of approximately $100 million.

       In 1996, TRINOVA increased its quarterly dividend to $.20 per share,
or $.80 per share for the year, from $.18 per share in 1995, or $.72 per share
for the year.  The $.20 quarterly rate was maintained in January 1997.

       In October 1995, TRINOVA announced that it may purchase up to
2 million of its outstanding common shares pursuant to a previously authorized
stock repurchase program.  Under this authorization, common shares may be
purchased from time to time in the open market and through privately
negotiated transactions.  Common shares purchased will be for the treasury and
will be available for general corporate purposes.  Through December 31, 1996,
TRINOVA has purchased 1,208,300 of its common shares at a cost of $37.7
million under the current authorization.  TRINOVA expects to make further
purchases in 1997, but is not committed to purchase a specific number of
shares.

       In 1996, TRINOVA filed a shelf registration statement with the
Securities and Exchange Commission and issued thereunder $100 million of
30-year debentures with a coupon rate of 7.875%.  Proceeds were used to retire
debt with shorter maturities, including $75 million that was classified as
long-term debt at December 31, 1995 under provisions of the revolving credit
agreement in effect at that date.  At December 31, 1996, additional debt
securities in amounts up to $150 million can be issued under existing shelf
registrations.

       In May 1996, TRINOVA sold its injection molding plastics products
facility in Bassett, Virginia, and during 1996 closed its Henderson, Kentucky,
and Grand Blanc, Michigan facilities.  TRINOVA announced in the 1996 fourth
quarter that it will close one of its automotive plastics products plants in
the 1997 first quarter.

                                      -4-

       In June 1996, TRINOVA acquired all of the outstanding shares of Summa
Manufacturing Corporation for approximately $7.4 million.  Summa is a leading
manufacturer of aftermarket vane pumps and replacement parts for mobile and
industrial applications.

       In December 1996, TRINOVA acquired certain assets and liabilities of
the Electrical Engineering & Manufacturing Company (EEMCO), a division of
DATRON, Inc., for approximately $35.9 million.  EEMCO designs and manufactures
linear and rotary actuators, specialty motors and generators, flight control
systems, electronic controls, and fully integrated actuation systems for
commercial and military aerospace applications.

       In 1996, TRINOVA sold its 35% interest in Yokohama Aeroquip K.K.,
based in Japan, and its 49% interest in Aeroquip Mexicana S.A., based in
Mexico.  Proceeds from the two transactions amounted to $37.3 million,
resulting in a net combined pretax gain of $17.3 million ($5 million net, or
$.16 per share).  The combined pretax gain included net translation gains of
$6.4 million previously deferred in the currency translation component of
equity.  Yokohama Aeroquip K.K. manufactured and sold fittings, couplings, and
hose and tube assemblies for industrial and automotive markets.  Aeroquip
Mexicana S.A. manufactured and sold rubber hydraulic hose and fittings in
Mexico, primarily for industrial markets.

(b)  "Note 12 - Business Segments" on pages 54-55 of Exhibit (13) filed
hereunder is incorporated herein by reference.

(c)  A description of the business done and intended to be done by TRINOVA and
its subsidiaries in each industry segment follows.

     (1) INDUSTRIAL:  Aeroquip manufactures and sells hose and hose
assemblies; hose fittings and adapters; tube fittings and adapters; couplings;
refrigeration/air conditioning connectors; and molded, extruded and co-
extruded plastic products.

       Vickers manufactures and sells hydraulic, electrohydraulic, pneumatic
and electronic control devices; piston and vane pumps and motors; open
architecture machine controls; hydraulic and pneumatic cylinders; hydraulic
power packages; electric motors and drives; hydraulic and lubrication
filtration; and fluid-evaluation products and services.

       Principal markets for these products include construction, mining,
logging and farm equipment; machine tool; process industries; electrical
machinery; air conditioning/refrigeration; appliances and communications
equipment; electronics; lift truck; material handling; plant maintenance; and
housing and commercial construction.  Sales are dispersed geographically
across a broad customer base.  Products are sold directly to original
equipment manufacturers ("OEMs") and through a worldwide network of
distributors serving aftermarket and small- and medium-sized OEM customers.

       The industrial business is highly competitive in terms of price,
quality and service.  TRINOVA believes that Aeroquip has significant market
position worldwide for industrial hose, fittings, couplings and adapters. 
TRINOVA also believes that Vickers has significant market position worldwide
for hydraulic and electrohydraulic controls; piston and vane pumps and motors;
hydraulic power packages; and electronic controls, drives and motors.  TRINOVA
serves many customers in the highly diverse and fragmented industrial markets. 
Due to the diversity of TRINOVA's products, there are a large number of

<PAGE>

                                      -5-

competitors scattered across a wide variety of market segments, with no single
competitor competing in each of TRINOVA's product lines.

       The order backlog for the industrial business was $184.9 million as of
December 31, 1996, compared to $201.5 million as of December 31, 1995. 
Substantially all of the December 31, 1996, backlog is expected to be filled
in 1997.

       (2)  AUTOMOTIVE:  Aeroquip manufactures and sells air conditioning,
power steering, and oil and transmission cooler hose and hose assemblies;
bodyside moldings; decorative bumper strips; roof moldings; spoilers; rocker
panel claddings; engine components; louvers and trim plates; interior trim;
garnish moldings; interior engine covers; instrument clusters; radio bezels;
and display products.  

       The automotive operations of Aeroquip serve worldwide automobile,
light truck, sport utility and van manufacturers.  Products are primarily sold
directly to manufacturers.  Approximately 62.7% of worldwide sales of
TRINOVA's automotive business are made to three major U.S. and one major
European automobile manufacturers.

       The automotive industry is highly competitive in terms of price,
quality and service.  Aeroquip is a preferred supplier to the major U.S. and
European automobile manufacturers.  Competition for products in the automotive
industry is very fragmented.  TRINOVA is currently seeking opportunities to
exit elements of its automotive segment relating to certain plastics
operations which have produced losses or relatively low operating margins in
recent periods.  The operations under review accounted for approximately 25%
of automotive sales in 1996.

       (3)  AEROSPACE:  Aeroquip manufactures and sells hose, fittings,
couplings, swivels, V-band couplings, fuel-handling products, high-pressure
tube fittings, clamps, marine bearings and noise-reduction products.

       Vickers manufactures and sells fixed- and variable-displacement pumps;
fuel pumps; hydraulic motors and motor packages; electric motorpumps and
generator packages; valves and valve packages; electrohydraulic and
electromechanical actuators; sensors and monitoring devices; and electronic
controllers.

       The aerospace operations of Aeroquip and Vickers serve worldwide
commercial aerospace and defense markets including commercial aircraft, air
defense, cargo handling, combat and support vehicles, commuter aircraft,
engines, marine, military aircraft, military weaponry, missiles and naval
machinery.  Products are sold directly to OEM businesses, commercial airlines
and the government and through a distributor network.  Approximately 14% of
TRINOVA's aerospace business sales are made to two major U.S. airframe
manufacturers.

       The aerospace business is highly competitive in terms of price,
quality and service.  TRINOVA believes that Aeroquip has significant market
position worldwide for aerospace hose, fittings and quick-disconnect
couplings.  TRINOVA also believes that Vickers has significant market position
worldwide for aerospace fixed- and variable-displacement hydraulic pumps,
hydraulic motors and motor packages, and aerospace sensors and monitoring
devices.

                                      -6-


       TRINOVA serves a large number of customers in the aerospace and
defense market.  Due to the diversity of TRINOVA's products, there are a large
number of competitors scattered across a wide variety of market segments, with
no single competitor competing in each of TRINOVA's product lines.

       The order backlog for the aerospace business was $341 million as of
December 31, 1996, compared to $266.4 million as of December 31, 1995. 
Approximately 13.3% of the December 31, 1996, backlog is not expected to be
filled in 1997 because certain contracts require deliveries after 1997. 
Approximately 35.8% of the December 31, 1996, backlog represents direct
government contracts or subcontracts on government programs, which are subject
to termination for convenience by the Government.

       (4)  OTHER INFORMATION:  TRINOVA and its subsidiaries are generally
not dependent upon any one source for raw materials or purchased components
essential to their businesses, and it is believed that such raw materials and
components will be available in adequate quantities to meet anticipated
production schedules.

       Patents owned by TRINOVA are considered important to the conduct of
its present businesses.  TRINOVA is licensed under a number of patents, none
of which are considered material to its businesses.  TRINOVA is the owner of a
number of U.S. and non-U.S. trademark registrations.

       TRINOVA devotes engineering, research and development efforts to new
products and improvement of existing products and production processes. 
During 1996, 1995 and 1994, TRINOVA spent a total of $74.9 million, $63
million and $55.5 million, respectively, on these efforts. 

       TRINOVA employed 15,162 persons at December 31, 1996.

(d)  "Note 13 - Non-U.S. Operations" on page 56 of Exhibit (13) filed
hereunder is incorporated herein by reference.  TRINOVA believes the risk
attendant to non-U.S. operations, which are primarily in developed countries,
is not significantly greater than that attendant to its U.S. operations.

ITEM 3.  Legal Proceedings.

       As previously reported, on March 26, 1992, the United States
Environmental Protection Agency ("USEPA") issued an Administrative Order ("106
Order") under Section 106 of the Comprehensive Environmental Response,
Compensation, and Liability Act ("CERCLA") to TRINOVA's subsidiary, Aeroquip
Corporation ("Aeroquip"), and five other Potentially Responsible Parties
("PRPs") relative to the San Fernando Valley Burbank Operable Unit ("BOU"),
involving groundwater contamination.  (Reference is made to Part I, Item 3, of
TRINOVA's Annual Report on Form 10-K for the year ended December 31, 1994.) 
The 106 Order requires the six PRPs to design and construct a water blending
facility at a cost now estimated to be approximately $5.7 million.  TRINOVA's
portion of any such cost is estimated to be 18.33% based on a cost-sharing
agreement among the six PRPs which was executed by TRINOVA on July 6, 1992.

       Also related to the BOU, on May 15, 1994, USEPA issued to Lockheed
Corporation ("Lockheed"), Aeroquip and other PRPs a Special Notice of
Liability under CERCLA for the remaining 18 years of operation and maintenance
(O&M) costs associated with the blending facility, as well as a water
treatment facility constructed by Lockheed under its BOU Consent Decree with
USEPA.  The Special Notice of Liability also covers USEPA's past response

<PAGE>

                                      -8-


costs.  On April 26, 1994, Lockheed filed an action against Aeroquip and 105
other PRPs seeking contribution toward costs Lockheed incurred to construct
the water treatment facility and related matters.  In November 1995, a
settlement agreement was entered into among Lockheed and most of the members
of a joint defense group (the "Joint Defense Group"), including Aeroquip,
which resolved this contribution action.  The settlement requires the payment
of $16 million by the Joint Defense Group.  Aeroquip's portion of this amount
is approximately $104,000.  This amount reflects a credit to Aeroquip for its
prior expenditures on the blending facility.  The settlement is also intended
to resolve Aeroquip's potential liability for the interim remedy at the
Glendale Superfund site (see below), Aeroquip's potential liability for a
toxic suit brought against Lockheed, and the claims by other Joint Defense
Group members against Aeroquip.  USEPA and some of the Burbank PRPs are
negotiating a Second Consent Decree which will provide the settling parties
with protection against liability for certain matters related to the interim
remedy now underway.  Under the proposed Second Consent Decree all work will
be carried out by the City of Burbank, and Lockheed will fund the Operation &
Maintenance costs.  Aeroquip and five other PRPs will be responsible for any
future design defects in the blending facility and for possible other costs
should USEPA decide to reopen the Consent Decree based on changed
circumstances or new information.

       As previously reported, on November 13, 1992, the USEPA, Region IX,
issued a General Notice of Liability letter to TRINOVA's subsidiary, Sterer
Engineering and Manufacturing Company, now known as the Fluid Control and
Actuation Division of Vickers, Incorporated ("Vickers").  (Reference is made
to Part I, Item 3, of TRINOVA's Annual Report on Form 10-K for the year ended
December 31, 1994.)  The letter notified Vickers of potential liability, as
defined by Section 107(a) of CERCLA, that it may incur with respect to the San
Fernando Valley Glendale South Operable Unit, involving groundwater
contamination.  The USEPA issued its Record of Decision ("ROD") on June 18,
1993.  Twenty-seven PRPs (the "PRP Group"), including Vickers, entered into an
Administrative Order on Consent with the USEPA on March 21, 1994, to conduct
the Remedial Design ("RD") of the interim remedy.  The estimated cost of the
RD is $4.7 million.  Vickers' portion of the RD costs is estimated to be 2.95%
based on an interim allocation agreement among the PRPs.  The interim remedy
for the Glendale Operable Units (including the North Operable Unit and the
South Operable Unit) is projected to cost in the range of $46-58 million.  The
PRP Group has entered into an agreement to carry out an allocation of the
costs for the Glendale Operable Units interim remedy.  The allocation process
must accommodate two separate allocations--first, the division of response
costs for the Glendale Operable Units between the Glendale PRPs and Lockheed
Corporation on behalf of all Burbank PRPs (see above) and, second, the
internal division of response costs among the Glendale PRPs.  Allocation of
costs between Lockheed and other PRPs remains unsettled.  As a result, on
November 26, 1996, the USEPA issued a Unilateral Administrative Order under
Section 106 of the Comprehensive Environmental Response, Compensation and
Liability Act to all PRPs, including Vickers, requiring the PRPs to conduct
the pre-construction phase of the interim remedy.  ITT has agreed to conduct
this Section 106 work, reserving its rights against all PRPs for contribution. 
While Vickers' allocated share of the remediation costs cannot be currently
estimated, the range of anticipated costs is between $600,000 and
$1.8 million.

       As previously reported, on July 31, 1992, the Maine Department of
Environmental Protection issued an Administrative Enforcement Order to TRINOVA
and its wholly owned subsidiaries, Aeroquip Corporation and Sterling

<PAGE>

                                      -9-

Engineered Products Inc. ("Sterling"), as well as one other party, Pioneer
Plastics Corporation ("Pioneer Plastics"), (collectively the "respondents"),
pursuant to Title 38, section 1304(12) of the Maine Revised Statutes. 
(Reference is made to Part I, Item 3, of TRINOVA's Annual Report on Form 10-K
for the year ended December 31, 1994.)  The Order, which was issued without a
prior hearing, required the respondents to conduct a complete Phase II
environmental assessment of alleged soil and groundwater contamination at a
manufacturing site in Auburn, Maine, which was formerly owned by Sterling and
is now owned by Pioneer Plastics.  The Order further required the respondents
to remediate any environmental contamination identified in the Phase II
assessment.   On May 5, 1993, a Compliance Order on Consent ("COC") was
entered into by the State of Maine, Sterling and Pioneer Plastics.  The COC
replaces and revokes the Order issued July 31, 1992.  The COC requires
Sterling to conduct a site investigation and to develop and implement a
remedial work plan.  The cost to Sterling to conduct the COC site
investigation, develop the remedial work plan and complete a feasibility study
(the "Feasibility Study") is estimated to be approximately $1,650,000. 
Sterling's remediation costs are undetermined at this time because the
Feasibility Study has not been completed.

       TRINOVA and certain subsidiaries are defendants in various lawsuits. 
While the ultimate outcome of these lawsuits and the above environmental
matters cannot now be predicted, management is of the opinion, based on the
facts now known to it, that the liability, if any, in these lawsuits (to the
extent not provided for by insurance or otherwise) and the above environmental
matters will not have a material adverse effect upon TRINOVA's consolidated
financial position.
