ITEM 1. BUSINESS.

OVERVIEW*

Sofamor Danek Group, Inc. is primarily involved in developing, manufacturing and
marketing devices, instruments, computer-assisted visualization products and
biomaterials used in the treatment of spinal and cranial disorders. The
objective of spinal implants is to increase spinal stability and facilitate the
bone growth required for fusion of the vertebrae of the spine. Demand for the
Company's products is affected by both the number of spinal fusions performed
and the percentage of these operations which utilize spinal implants.

The Company is an Indiana corporation formed in 1983. The Company changed its
name from Biotechnology, Inc. to Danek Group, Inc. in August 1990, and from
Danek Group, Inc. to Sofamor Danek Group, Inc. in June 1993. Sofamor Danek
Group, Inc.'s principal offices are located at 1800 Pyramid Place, Memphis,
Tennessee 38132, and its telephone number is (901) 396-2695. As used in this
Report, unless the context indicates otherwise, Sofamor Danek Group, Inc. and
its subsidiaries are collectively referred to as the "Company" and, unless
otherwise indicated, all subsidiaries are wholly owned. "Sofamor" and "Danek"
are trademarks of the Company.

The executive offices, administrative offices and U.S. distribution facility of
the Company are located in Memphis, Tennessee, and its U.S. manufacturing
operations are conducted near Warsaw, Indiana, Broomfield, Colorado and West
Palm Beach, Florida. The Company also has a major manufacturing and distribution
facility in Rang-du-Fliers, France and distributes its products primarily
through its subsidiaries in France, Germany, Spain, Italy, Hong Kong, Japan, the
Benelux region, Australia, Korea, Puerto Rico, South Africa, the United Kingdom
and Canada.

The Company's principal products include the TSRH(R) Spinal System, the
Cotrel-Dubousset line of products and the ORION(R) Anterior Cervical Plate
System (the "ORION System") and the STEALTHSTATION(TM). The Company's spinal
systems include the TSRH(R) Spinal System, the CD(TM) line of products and the
ORION(R) System. These lines of surgical implants include tools for fusion such
as rods, plates, screws, hooks, locking bolts and transverse traction devices
that lock implants together. The Company markets products which treat
degenerative diseases, deformities and trauma in all regions of the spine.
Spinal surgeons and neurosurgeons choose a spinal implant system based on, among
other things, the nature and location of the spinal instability. The Company
currently markets approximately 33 spinal implant product lines. The
STEALTHSTATION(TM) is an advanced computer-assisted, image-guided surgery system
which provides surgeons with the capability to plan, navigate and precisely
position surgical tools and devices during cranial, spinal, ear, nose and throat
procedures. Additional new products are now under development. (See
"Business--New Product Opportunities.")

The Company expanded its product line in 1996 with the acquisition of MedNext,
Inc., Surgical Navigation Technologies, Inc. and certain net assets of TiMesh
Inc. MedNext's product line consists of a high-speed pneumatic

Surgical Navigation's product line consists of frameless stereotactic surgical
products relating to the spinal and neurological fields. The Timesh product line
includes titanium plates and alloy screws used to treat conditions in the
cranial (head and facial) region.

The Company's strategy is to continue its focus on product development and
marketing to its worldwide customer base. The Company markets its products in
the U.S. to spinal surgeons through its network of approximately 200 independent
commissioned sales representatives. The Company markets its products
internationally to spinal surgeons in approximately 60 countries primarily
through a network of independent distributors and agents. In France, Germany,
Spain, Italy, Hong Kong, Japan, the Benelux region, Australia, New Zealand,
Korea, Puerto Rico, South Africa, the United Kingdom and Canada, the Company's
subsidiaries distribute products.

USE OF SPINAL IMPLANTS

Spinal fusions are performed to treat diseases and conditions such as the
following:

         DEGENERATIVE DISEASES. Typically occurring in mature adults,
         degenerative diseases of the spine can result in immobility, pinched
         nerves and associated pain for the patient.

         DEFORMITIES. Deformities, unless treated at a young age, can prevent
         proper growth of the spine and can be life threatening if allowed to
         progress. Spinal implants straighten the spine to allow for proper
         alignment of internal organs.

         TRAUMA. The typical cause of traumatic spinal conditions is automobile
         accidents.

The objective of spinal implants is to increase spinal stability and facilitate
the bone growth required for fusion of the vertebrae of the spine. Fusion
immobilizes the vertebrae, which generally relieves the pressure on the nerves
of the spinal column and alleviates chronic back pain. Approximately 500,000
spinal fusion procedures were performed worldwide in 1997, and spinal implants
(commonly referred to as "instrumentation") are currently used in approximately
40% of these procedures. The Company believes that the success rate for fusion
with instrumentation is over 90%. Spinal implant procedure growth will be driven
by continued penetration of instrumentation, technological advances and
demographics. A surgeon's decision to treat a spinal condition with an implant
is based on many factors. The relative severity of the patient's condition, such
as the degree of the curvature of the spine, is assessed against the potential
risks and benefits of the spinal operation. The age of the patient, the
patient's medical history and the physical condition of the patient (i.e., the
ability to withstand surgery) are all important considerations in deciding which
treatment path to implement.

Until the mid-1980's, surgeons had limited implant options for treating spinal
conditions. Surgeons treating spinal conditions either did so without implants
or utilized basic implant devices. These devices often did not, however,
sufficiently immobilize the spine, and thus limited the fusion rate and efficacy
of the procedures. In seeking better alternatives for spinal fusions, surgeons
began to use implants designed primarily to provide greater structural support
for the spine, which would enhance the healing process. Over the last several
years, clinical studies have shown that surgeries using spinal implants are more
effective in immobilizing the spine than surgeries in which implants are not
used.

PRINCIPAL PRODUCTS

TSRH(R) SPINAL SYSTEM

The TSRH(R) Spinal System traces its origins to research conducted at the Texas
Scottish Rite Hospital in Dallas, Texas and is used primarily to treat patients
afflicted with degenerative diseases, scoliosis (curvature of the spine) or
other spinal deformities. The system consists of specialized hooks, plates and
screws that are attached to rods 




                                       2
<PAGE>   6

through locking bolts, which the Company believes allows for increased torsional
and axial spinal support. There are special configurations of the system
available to address specific applications such as pediatric surgery and adult
lumbar surgery. The Company manufactures and distributes the TSRH(R) Spinal
System under agreements pursuant to which the Company has received the exclusive
worldwide rights to the products in exchange for royalty payments. Sales of the
TSRH(R) Spinal System accounted for 24% of the Company's revenues in 1997, 33%
in 1996 and 38% in 1995.

Since its introduction in 1989, the Company has added enhancements to the
TSRH(R) Spinal System, including the Variable Angle Screw, Central Post Hook,
Lateral Offset Plate, Open Eyebolt and Top Tightening components. The Variable
Angle Screw provides flexibility in screw placement in relation to the spinal
rod. Similarly, the Central Post Hook offers versatility in hook placement. The
Lateral Offset Plate allows variations in the lateral distance between a hook or
sacral screw and the spinal rod. The Open Eyebolt can be used when an eyebolt
must be added after all hooks and CROSSLINK(R) plates are in place. The Top
Tightening components incorporate T-bolts, hooks, sacral/iliac screws and
staples into a comprehensive spinal implant system. These enhancements provide
interchangeability of components and improved ease of use for surgeons. The
TSRH(R) Spinal System is covered by various patents.

COTREL-DUBOUSSET LINE OF PRODUCTS

The Cotrel-Dubousset line of products was developed by Dr. Yves Paul Cotrel in
cooperation with Sofamor and with the assistance of Professor Jean Dubousset.
This product line includes the CD(TM) Spinal Instrumentation System (the "CD(TM)
System"), the Compact CD or CCD(TM) System (the "CCD(TM) System") and the CD
HORIZON(R) Spinal System (the "CD HORIZON(R) System"). The CD(TM) System was
introduced in 1984 and was designed primarily to treat patients afflicted with
spinal deformities and fractures of the spine in the thoracic and lumbar
regions. The principal components of the CD(TM) System include spinal rods,
hooks, sacral screws and transverse traction devices which lock implants
together and a wide range of instruments used to position and secure the
implants. The CCD(TM) System was designed principally for the treatment of
degenerative spinal conditions of the lumbar and sacral spine. The CD HORIZON(R)
System combines new, low profile hooks and screws with components of several
other systems for the treatment of various spinal conditions. Sales of the
Cotrel-Dubousset line of products accounted for 17% of the Company's revenues in
1997, 23% in 1996 and 26% in 1995.

ORION(R) ANTERIOR CERVICAL PLATE SYSTEM

The ORION(R) System was introduced by the Company in 1994. This system is
indicated for use in stabilizing the anterior cervical spine during the
development of a solid spinal fusion in patients with degenerative diseases,
traumatic fractures and tumors. The system consists of a plate and screws which
attach to the anterior cervical spine (front part of the neck). The Company
manufactures and distributes the ORION(R) System under agreements pursuant to
which the Company obtained the exclusive worldwide rights to the products in
exchange for royalty payments. The ORION(R) System accounted for 11% of the
Company's revenues in 1997, 10% in 1996 and 8% in 1995.

STEALTHSTATION(TM) SYSTEM

The STEALTHSTATION(TM) System is an advanced computer-assisted, image-guided
surgery system which provides surgeons with the capability to plan, navigate and
precisely position surgical tools and devices during cranial, spinal, ear, nose
and throat procedures. Specifically, the STEALTHSTATION(TM) System allows
surgeons to take standard image data sets from practically any image source (CT,
MR, etc.) and transform them into a three-dimensional image. Surgeons can use
the system to plan the most desirable path through critical anatomy, then move
seamlessly into the operating room where this image data is registered, or
matched, to the patient's actual anatomy. Thus, the STEALTHSTATION(TM) System
enhances the accuracy of delicate surgical procedures. The STEALTHSTATION(TM)
System assists the surgeon by precisely identifying in real-time the location of
a surgical 





                                       3
<PAGE>   7

instrument's tip in relation to the patient's preoperative diagnostic imaging
scan. The Company believes that use of the STEALTHSTATION(TM) System
significantly reduces operating room time and the length of the patient's
hospital stay, which has reduced the overall cost of such procedures. The
Company obtained initial FDA marketing clearance for the STEALTHSTATION(TM)
System in January 1996 for use throughout the body. The Company believes the
STEALTHSTATION(TM) System is the leading frameless stereotactic image-guided
surgery system in the world. The Company generates recurring revenue from this
product from annual maintenance contracts, software upgrades and product
enhancements.

Each of the TSRH, CD, CCD, CD HORIZON, ORION and STEALTHSTATION Systems is
marketed in the U.S. as a spinal device system and is covered by various
patents; "TSRH," "CD," "CCD," "CD HORIZON," "ORION," and "STEALTHSTATION" are
trademarks of the Company. (See "Business-Government Regulations.")

MARKETING AND DISTRIBUTION

Sofamor Danek markets its spinal implant and surgical systems products in the
United States directly to the spinal surgeons and neurosurgeons who perform
spinal and cranial surgery. The Company distributes its products through its
unique network of approximately 200 commissioned, dedicated sales
representatives. The Company markets its products internationally directly to
spinal surgeons and neurosurgeons in major markets including the Benelux region,
France, Germany, Italy, Spain, the United Kingdom, Canada, South Africa, Puerto
Rico, Hong Kong, Japan, Korea, Australia and New Zealand, and indirectly in
approximately 60 other countries through a network of independent distributors
and agents. The Company believes that its distribution capabilities provide it
with significant competitive advantages by facilitating strong relationships
with the physicians, hospitals and clinics that comprise the Company's customer
base. The Company strengthens these relationships by organizing and sponsoring
the education of surgeons through medical symposia, seminars, payor relations
and practice management consulting. In order to meet the needs of hospitals and
clinics, the Company offers instrument and implant purchase alternatives. For
example, the Company offers a "loaner program" whereby a complete implant system
is shipped overnight for next-day surgery. The customer is charged only for the
components used, and a premium over the published list price is charged to
defray the additional cost of the program. The Company's premier distribution
capability also enables it to attract alliance partners who seek its
distribution breadth.

International sales have amounted to $101.5 million and $82.3 million,
representing approximately 32% and 34% of total sales in 1997 and 1996,
respectively.

The Company's backlog of firm orders is not considered material to an
understanding of its business.

MANUFACTURING AND QUALITY CONTROL

The Company's products are manufactured in the United States primarily by the
Company's subsidiary, Warsaw Orthopedic, Inc., which the Company acquired in
1983. The Company's products are also manufactured by its subsidiaries, SNT,
located in Broomfield, Colorado, and MedNext of West Palm Beach, Florida. The
Company believes that its current assets will provide it with sufficient
manufacturing capacity for the future. As a medical device manufacturer, the
Company is subject to the FDA's stringent QSR and regulations as stipulated by
the FDA. The Company has installed computer controlled machinery in its
manufacturing operations, resulting in greater flexibility in the manufacturing
process and enabling the Company to be cost efficient. The Company also utilizes
comprehensive, integrated MIS (management information system) software for
production, planning and scheduling. The Company employs a broad range of
inspection and quality assurance standards. The Company utilizes in-process
testing and inspection methods in the manufacturing process to produce quality
products. The design and layout of the Company's manufacturing facilities
affords the Company flexibility to increase production capacity. Outside the
United States, product manufacturing is done primarily by Sofamor in
Rang-du-Fliers, France. Some of the manufacturing outside the United States is
performed by subcontractors. Sofamor has a 33.75% equity investment in one of
the subcontractors. See "--Government Regulation."

RESEARCH AND PRODUCT DEVELOPMENT

In addition to its currently marketed products, the Company has a broad pipeline
of spinal and neurosurgical products under development to augment its existing
product offerings and further advance the state of the art of surgical and
diagnostic procedures. Key products under development include the Novus Cage,
which is an interbody fusion device approved for use in certain non-U.S.
countries, biological products to induce bone growth, prosthetic discs and
visualization technology to aid surgeons. The Company incurred research and
development expense of approximately $19.7 million, $15.9 million and $14.0
million for the years ended December 31, 1997, 1996 and 1995, respectively.

NEW PRODUCT OPPORTUNITIES

BIOLOGICAL PRODUCTS FOR USE IN SPINAL RECONSTRUCTION

In February 1995, the Company entered into a strategic alliance with Genetics
Institute to develop biological products for use in spinal applications. These
products are being designed to use Genetics Institute's recombinant human bone
morphogenetic protein rhBMP-2 to induce bone growth for the treatment of spinal
disorders and replace the current therapy, which is transplantation of bone
tissue from the pelvis of the patient. The Company has completed an FDA approved
pilot study in which all 11 patients achieved fusion in three months. Typically,
fusion can take between 15 to 18 months to occur. The Company is currently
submitting an IDE to conduct a pivotal study with respect to rhBMP-2. The
Company has obtained exclusive North American rights to these rhBMP-2
proprietary technologies and patents for spinal applications. Pursuant to the
terms of the license agreement, the Company will pay the Genetics Institute $50
million over four years, of which $12.5 million was paid in each of 1995 and
1996 and $17.5 million was paid in 1997. An additional $7.5 million is due in
1998. FDA review and approval, which will require the conduct of clinical
trials, will also be necessary to market these biological products. The Company
will purchase the rhBMP-2 product from Genetics Institute. The Company is
considering a variety of different carriers for the Genetics Institute proteins.
One potential carrier is a porous polymer to which the Company has obtained
worldwide rights under an exclusive license. If this porous polymer carrier is
utilized with rhBMP-2, royalty payments will be due to the owner of the polymer
technology. See "Risk Factors -- Uncertainty of Regulatory Clearances;
Regulatory Compliance" and "-- Dependence on Patents and Proprietary
Technology."

NOVUS CAGE

In addition to the cages that it currently markets, the Company is developing a
wide variety of products that the Company believes will more effectively meet
patient needs in the cage segment. These products include cages designed to more
accurately match the anatomy of the spine to ease insertion and conserve the
patient's bone. These products will utilize materials that are designed to
better match the characteristics of bone and/or allow the bone to better
incorporate into the implant. The Company has also entered into a licensing
agreement for the worldwide rights to these patented technologies covering
implants, instruments and methodologies for simultaneously performing a
discectomy, a fusion and an internal stabilization of the spine.

PROSTHETIC DISC PROGRAM

The Company is actively evaluating various designs for the replacement of
diseased and/or damaged discs. These designs are at various stages of
development and would ultimately require pre-market approval by the FDA prior to
marketing in the United States.

VISUALIZATION TECHNOLOGIES

In January 1998, the Company entered into a cooperative technology agreement
with Vista to develop and distribute new advanced visualization systems based on
Vista's proprietary high resolution digital technology. Pursuant to the
agreement, the Company will have the worldwide distribution rights to these new
products for use in neurosurgery, spinal surgery and otolaryngological surgery.

There can be no assurances that the products described above in this section
will be marketed or that FDA authorization will be received. Spinal implants,
image guidance and other related devices are typically rendered obsolete within
a few years. While the Company maintains active research and development
programs, there can be no assurance that it will be able to develop and
introduce new products that will enable it to remain competitive in the future.
See "Risk Factors--Rapid Technological Change and Risk of Technological
Obsolescence."

GOVERNMENT REGULATION

In the United States, the Company is subject to regulation by the FDA. FDA
regulations govern the testing, labeling, promotion and sale of medical devices
and require the Company to maintain certain standards and practices with respect
to the manufacturing and labeling of devices, the maintenance of certain records
and medical device reporting. The Company's facilities and records are subject
to FDA inspections.

The FDA is the agency responsible for the regulation of medical devices in the
United States pursuant to the Food, Drug and Cosmetic Act (as amended by the
1976 Medical Devices Amendment), the Safe Medical Devices Act of 1990 (as
amended in 1992), the Food and Drug Administration Modernization Act of 1997,
the regulations promulgated thereunder and guidance documents and instructions
issued by the FDA. In general, prior to entering commercial distribution,
medical devices must undergo FDA review, either pursuant to a 510(k)
notification or a PMA application filed by the manufacturer of the device. A
510(k) notification is a filing submitted to demonstrate that the device in
question and its labeling are "substantially equivalent" to a "legally marketed
device" and its labeling. In contrast, a PMA application must demonstrate that
the device is safe and effective; it is a more complex submission that typically
includes a two-year follow-up of a controlled human clinical study. Factors that
dictate whether a 510(k) notification or a PMA application is required include:
whether the device and its labeling are "substantially equivalent" to a "legally
marketed device" and its labeling. The process of obtaining marketing
authorizations can be time consuming, and there can be no assurance that all the
necessary authorizations will be granted to the Company with respect to new
products and devices developed by the Company.

All of the Company's implants currently marketed in the United States are
covered by 510(k) notifications with limited exceptions. As devices become
increasingly innovative, it is difficult to establish that a device is
"substantially equivalent" to another "legally marketed device" and thereby
obtain 510(k) clearance for a new product. Additionally, as clarified by the
Safe Medical Devices Act of 1990, the FDA could, and generally does, decide to
require the submission of additional data. It is impossible to predict whether
additional changes will be made in the 510(k) clearance practices and whether
any such changes could have an adverse effect on the Company and its business.
The Company cannot predict the extent or impact of future federal, state or
local legislation or regulation.

If human clinical trials of a device are required and if the device presents a
"significant risk," the manufacturer or distributor of the device is required to
file an IDE application with the FDA prior to commencing human clinical trials.
The IDE application must be supported by data, typically the result of animal,
and, possibly, mechanical testing. If the IDE application is approved by the
FDA, human clinical trials may begin at a specific number of investigational
sites with a maximum number of patients, as approved by the FDA.

Federal law provides that manufacturers can label and promote new medical
devices only for indications that have been allowed by the FDA. Since the FDA
does not regulate the practice of medicine, physicians may use products 




                                       6
<PAGE>   10

for applications that have not yet been cleared by the FDA for such a labeling
indication if such use is deemed in their medical judgment to be in the
patient's best interests. Thus, as part of the practice of medicine, physicians
may at their discretion and in the exercise of their medical judgment use any
legally marketed screws for indications not in the labeling. Although this
practice may continue in the future, the Company does not encourage nor can it
predict such use.

In October 1997, the Company received 510(k) clearance to begin labeling and
marketing its CD Spinal System with the following restrictions. As a pedicle
screw fixation system, the device system is intended only for: (a) degenerative
disc disease (defined as back pain of discogenic origin with degeneration of the
disc confirmed by patient history and radiographic studies) for noncervical
screw fixation; and (b) for severe spondylolisthesis (Grades 3 and 4) at the
L5-S1 joint in patients who are receiving fusions using autogenous bone graft
only and who are having the device removed after the development of a solid
fusion for screw fixation from L3 to the sacrum. Additional warnings in the
package insert regarding the potential risks and unestablished benefits of the
device were also required.

In January 1995, the Company received 510(k) clearance to begin labeling and
marketing the stainless steel version of the TSRH(R) Spinal System for pedicle
screw attachment only for treating selected patients with grade 3 or 4 severe
spondylolisthesis of the fifth lumbar-first sacral (L5-S1) vertebral joint. The
clearance is based on this spinal system having been found equivalent only to
similar device systems labeled and intended for patients: (a) who have severe
spondylolisthesis (grades 3 and 4) of the fifth lumbar-first sacral (L5-S1)
vertebral joint; (b) who are receiving fusions using autogenous bone graft only;
(c) who are having the device fixed or attached to the lumbar and sacral spine;
and (d) who are having the device removed after the development of a solid
fusion mass. This clearance requires the addition of specific warnings to the
labeling of the product. Since that time, many other systems offered by the
Company have received clearance for similar labeling.

In May 1990, the Director of the FDA's Division of Compliance Operations for the
Center for Devices and Radiological Health sent a letter to approximately 80
manufacturers and distributors of medical devices, including the Company, which
advised that companies must not label, or in any way promote, devices to be used
in the United States for pedicular screw attachment to, or fixation of, the
vertebral column. The Company examined all of its literature and voluntarily
recalled one brochure used to recruit clinical investigators. This recall was
examined for effectiveness by the FDA beginning in May 1991 and found to be
complete in February 1992. In August 1993, the Company and six other companies
received warning letters from the FDA, primarily regarding the issue of
supporting medical education programs where physicians "demonstrate" the use of
screws in the pedicle of the spine. The Company responded to the warning letter,
and no official response from the FDA has ever been received. In February 1995,
the Company received a warning letter from the FDA regarding the wording in a
Company press release and "Dear Doctor" letter relating to the January 1995
510(k) clearance referred to above. The Company submitted a written response to
the FDA on March 17, 1995 and took certain actions in response to the letter.
The Company believes that it has taken all the appropriate actions possible
regarding this matter.

With respect to a different but related matter, in April and June 1994, many
orthopedic companies received letters from the FDA stating that certain warning
statements must appear on all labeling of certain devices. The Company believes
it is complying with all labeling requirements for those devices in the United
States that need such warning statements.

The Company cannot, however, rule out the possibility that the FDA could bring a
regulatory action without further notice against the Company with respect to any
of the matters referred to above. Such regulatory action might include, but
would not be limited to, civil and/or criminal penalties, an injunction against
any distribution in the United States, seizure, fines and/or recall of any
Company product or labeling. The inability to continue to sell certain products
could have a material adverse impact on the Company's business and financial
condition.





                                       7
<PAGE>   11

The Company's products are also subject to regulation by foreign governmental
and regulatory authorities. The Company believes that it has all necessary
foreign authorizations where its products are sold. There can be no assurances
that foreign regulatory requirements will not become more stringent in the
future. In Europe, individual European Union ("EU") members have required
compliance and testing for some devices (e.g., electromedical devices), but in
most countries testing of implants has been voluntary.

A Medical Devices Directive (the "Directive") for the EU was adopted on June 14,
1993. Proof of compliance with the harmonized standards will be presumptive
proof of compliance with the legal requirements in each EU member country. If
compliance with the standards cannot be demonstrated or standards have not been
issued for the product in question, the manufacturer will have to supply an
application that proves the product is safe and effective. While there is
uncertainty as to the specific national enabling legislation, the Company does
not anticipate any special concerns uniquely applicable to the Company since
this legislation affects all medical device manufacturers and distributors.
There can be no assurance that new legislation will not cause delays or
disruptions in the marketing of the Company's products in Europe. In 1995, the
Company's Memphis, Warsaw and French facilities were ISO 9001 certified pursuant
to the Directive. The Company believes it is well positioned to compete in the
European market when the regulations take full effect in 1998.

All of the Company's products are prescription devices for sale in the United
States only by or on the order of a physician. Neither this document nor any
other communication to the financial community by the Company is intended or
should be construed as labeling for the Company's products. Any learned
intermediary or health care professional who reads this document or any other
communication to the financial community should not rely on this document for
decisions to purchase, indications in use and/or instructions in use. Instead,
any health care professionals who may read this or any other Company document
should see, read and follow all package inserts accompanying the Company's
products. (See Item 7, "Management's Discussion and Analysis of Results of
Operations and Financial Condition--Factors That May Affect Future Operating
Results and Financial Condition--Regulatory Approvals.")

COMPETITION

The medical device industry is subject to intense competition. The market for
products designed to treat spinal conditions is highly competitive, and the
Company expects competition to increase. Accordingly, the Company's future
success will depend in part on its ability to respond quickly to medical and
technological change and user preferences through the development and
introduction of new products that are of high quality and that address patient
and surgeon requirements and, in part, on its ability to differentiate its
mature products from those of its competitors. Worldwide, there are many firms
producing spinal implant devices, and certain of the Company's competitors
currently manufacture and sell interbody fusion cages that have received
clearance from the FDA. A number of the Company's competitors have greater
financial, research and development, manufacturing and sales and marketing
resources than the Company. The Company's inability to compete effectively
against existing or future competitors would have a material adverse effect on
its business, financial condition and results of operations.

The Company believes that the primary competitive factors in the market for
treatment of spinal disorders include regulatory approvals, clinical and patient
acceptance, post-operative discomfort, ease of use, product performance,
marketing and sales capability and the enforceability of patent and other
proprietary rights. The Company believes that it is, and will continue to be, a
leader with respect to these factors. The Company believes that it successfully
competes based on (i) the quality of the Company's products and their ease and
versatility of use by surgeons, (ii) the introduction of new products and
systems, (iii) the Company's emphasis on research and development, (iv) the
Company's focus on spinal products coupled with a solid infrastructure of
experienced management personnel, (v) the Company's association with spinal
surgeons and neurosurgeons and (vi) the Company's participation, through medical
symposia and seminars, in the education of surgeons in the cleared uses of
implant products. See "Risk Factors--Increasing Competition."

EMPLOYEES

The Company had approximately 1,000 employees at December 31, 1997. No U.S.
employee of the Company is represented by a labor union or is subject to a
collective bargaining agreement. All of the employees outside the United States
are covered by applicable industry collective bargaining agreements as may be
required by government authorities in the respective countries where those
employees are located. The Company has never experienced a work stoppage due to
labor difficulties.

PATENTS, TRADEMARKS AND COPYRIGHTS

As of December 31, 1997, the Company owned or held licenses to 208 inventions
covered by 348 patents and had 422 applications pending on 141 more inventions
covering the full spectrum of its product lines in the United States and major
countries throughout the world. In addition, the Company has acquired rights
under various purchase, license or distribution agreements related to the
design, manufacture and distribution of certain products and devices. The
Company has 38 registered trademarks and applications pending for registration
on 36 other marks in the United States and other major countries throughout the
world. The Company currently has six registered copyrights for certain of its
product manuals and two other applications pending. See "--Principal Products"
and "Risk Factors--Dependence on Patents and Proprietary Technology." (See Item
7, "Management's Discussion and Analysis of Results of Operations and Financial
Condition--Factors That May Affect Future Operating Results and Financial
Condition--Intellectual Property.")

ROYALTY AND OTHER PAYMENTS

The Company has agreements with certain unaffiliated entities which provide the
Company with the rights to manufacture and market certain spinal system products
developed by these entities. The agreements generally provide for payments
ranging from 1% to 10% of the net selling prices (as defined by the agreements)
of all such products sold. These agreements are in force as long as the Company
sells these products. Royalty expenses and licensing fees made pursuant to the
agreements referred to above during fiscal years 1997, 1996 and 1995 were
approximately $9.1 million, $6.8 million and $5.9 million, respectively.

RAW MATERIALS

Implant grade stainless steel and titanium alloy account for the majority of the
Company's raw material purchases. There are multiple sources from which the
Company may purchase this type of stainless steel and titanium alloy, and it is
available within one to eight months of the time an order is placed. Titanium
alloy provides less MRI (magnetic resonance image) interference during imaging
of the patient during postoperative follow-up.

PRINCIPAL CUSTOMERS

The Company does not rely on any single hospital or clinic for a material
portion of its business. The Company has over 4,000 hospital and clinic
customers, none of which accounts for more than 2% of sales.

For information relating to the amounts of revenue, operating profit or loss and
identifiable assets attributable to each of the Company's geographic areas, see
"Notes to Consolidated Financial Statements--Foreign Operations," which are
incorporated by reference herein.

ENVIRONMENTAL

The Company believes it is in compliance in all material respects with all
applicable environmental regulations and does not expect to require a material
amount of capital expenditures in order to remain in compliance.

INSURANCE

The Company carries comprehensive and general liability insurance, as well as
coverage for product liability. The Company also carries liability insurance
coverage for directors and officers. Such directors' and officers' policy
contains certain exclusions, including, but not limited to, certain claims by
stockholders. (See Item 3, "Legal Proceedings" and Item 7, "Management's
Discussion and Analysis of Results of Operations and Financial Condition--
Factors That May Affect Future Operating Results and Financial
Condition--Product Liability; Insurance.")

ITEM 2. PROPERTIES.

The Company's headquarters and primary U.S. distribution facility are located in
Memphis, Tennessee. The Company utilizes a 60,000 square foot owned facility and
9,730 square feet of leased space for these functions. The Company is in need of
additional office and distribution space at its Memphis location and is planning
to lease a 106,000 square foot building that is currently under construction
adjacent to its corporate headquarters. The primary U.S. manufacturing
operations of the Company are conducted in an 83,000 square foot plant located
near Warsaw, Indiana, under a lease which expires December 31, 1999, with four
one-year extensions available thereafter. Approximately 33,000 square feet of
the Warsaw facility are currently not used by the Company. Management believes
that the Company's Warsaw facility is suitable for its current use and adequate
for the Company's operation for the foreseeable future. The Rang-du-Fliers,
France location utilizes a 57,500 square foot facility situated on 10.8 acres of
land owned by Sofamor, which also has approximately 16,000 square feet of leased
office space in Paris used for marketing, sales, development and administrative
activities. Subsidiaries of the Company have leased office space in Milan,
Italy, Cologne, Germany, Epping, NSW, Australia, Seoul, Korea, San Juan, Puerto
Rico, Mississauga, Canada, Saint Genis Laval, France, Hong Kong, Madrid, Spain,
Tokyo and Osaka, Japan, Luxembourg City, Luxembourg, Broomfield, Colorado and
West Palm Beach, Florida.

ITEM 3.  LEGAL PROCEEDINGS.

The Company is involved from time to time in litigation on various matters which
are routine to the conduct of this business, including product liability and
intellectual property cases.

PRODUCT LIABILITY LITIGATION

Beginning in 1994, the Company and other spinal implant manufacturers were named
as defendants in a number of product liability lawsuits brought in various
federal and state courts around the country. These lawsuits allege that
plaintiffs were injured by spinal implants manufactured by the Company and
others. The essence of the plaintiff's claims appears to be that the Company
(including Sofamor and its former U.S. distributor) marketed some of its spinal
systems for pedicle fixation in contravention of FDA rules and regulations
(governing marketing and labeling of medical devices), that pedicle fixation has
not been proven safe and effective in the context of FDA labeling standards,
that some or all of the spinal systems are defectively designed and manufactured
and that plaintiffs have suffered a variety of injuries as a result of their
physicians' use of such systems in pedicle fixation. The Company has also been
named as a defendant in a number of lawsuits instituted by plaintiffs who have
received spinal implants manufactured by other manufacturers and in which the
Company is alleged to have participated in a conspiracy among doctors,
manufacturers, hospitals, teaching institutions, professional societies and
others to promote, in violation of applicable law, the use of spinal implants.

In a number of cases, plaintiffs have sought to proceed as representatives of
classes of spinal implant recipients. All efforts to obtain class certification
have been denied or withdrawn, except with respect to a class-action settlement
entered into between the plaintiffs and another spinal implant manufacturer,
AcroMed Corporation (see below under the heading entitled "AcroMed Corporation
Settlement"). Some plaintiffs have filed individual lawsuits, whereas other
lawsuits list multiple plaintiffs and, in certain instances, multiple lawsuits
have been filed on behalf of the 





                                       10
<PAGE>   14

same individual plaintiffs. Plaintiffs typically seek relief in the form of
monetary damages, often in unspecified amounts. Many of the plaintiffs only
allege as monetary damage an amount in excess of the jurisdictional minimum for
the court in which the case has been filed. A few suits also name as defendants
various officers and directors of the Company.

As of December 31, 1997, approximately 2,800 plaintiffs were joined in lawsuits
against the Company. A number of plaintiffs have failed to pursue the claims
made on their behalf and their claims were dismissed without prejudice. As of
March 31, 1998, the claims of approximately 2,200 plaintiffs remain active in
the litigation. As of December 31, 1997, the Company was also named as a
defendant in lawsuits involving about 2,600 plaintiffs where the Company is
alleged to have conspired with competitors and others legally to promote the use
of spinal implant systems.

The Company believes that it has defenses, including, without limitation,
defenses based upon the failure of a cause of action to exist where no
malfunction of the implant has occurred or the plaintiff has suffered no injury
attributable to the Company's product, the expiration of the applicable statute
of limitations and the learned intermediary defense. The Company has asserted
and will continue to assert these defenses primarily through the filing of
dispositive motions. The Company believes that all product liability lawsuits
currently pending against it are without merit and will continue to defend
against them vigorously.

FEDERAL MULTIDISTRICT LITIGATION (MDL 1014)

On August 4, 1994, the Federal Judicial Panel for Multidistrict Litigation
ordered all federal court lawsuits to be transferred to and consolidated for
pretrial proceedings, including the determination of class certification, in the
United States District Court for the Eastern District of Pennsylvania in
Philadelphia (the "Multidistrict Litigation"). Lawsuits filed in federal court
after August 4, 1994 have also been transferred to and consolidated in the
Multidistrict Litigation in the Eastern District of Pennsylvania. In addition, a
number of lawsuits filed in state courts around the country were removed to
federal courts and then transferred into the Multidistrict Litigation. On
February 22, 1995, Chief Judge Emeritus, Louis C. Bechtle, denied class
certification. A large number of plaintiffs filed individual lawsuits as a
result of the denial of class certification. In some instances, lawsuits that
had been removed and transferred into the Multidistrict Litigation have been
remanded to the state courts in which they were filed because there was no
federal court jurisdiction. As of December 31, 1997, the Company is a defendant
in approximately 920 individual claims and 1,065 conspiracy claims consolidated
in the Multidistrict Litigation. On April 16, 1997, Judge Bechtle dismissed
conspiracy claims alleging fraud on the FDA, but deferred the remaining
conspiracy claims for later consideration by the federal trial courts to whom
the cases will be remanded for trial.

Discovery has been completed in a number of the federal court cases and is
continuing in the remainder. A small number of cases have been transferred to
the federal courts in which they were filed for further proceedings and trial.
Judge Bechtle has begun the process of transferring the remaining federal court
cases to various federal courts throughout the United States. As of December 31,
1997, the Federal Judicial Panel on Multidistrict Litigation ordered the remand
of approximately 210 cases to transferor courts for further proceedings. It is
not now possible to determine when the first federal court cases will be tried.

STATE COURT LITIGATION

A number of cases filed in state courts were not eligible for removal and
transfer into the Multidistrict Litigation. As of December 31, 1997, there were
approximately 1,800 individual claims pending against the Company in several
courts around the country, principally in Tennessee, Oklahoma, Texas and
Pennsylvania. In addition, there were approximately 1,600 conspiracy claims
pending in state courts.

Approximately 1,550 plaintiffs who had joined together in several complaints
which had been removed to the Multidistrict Litigation proceedings have had
their cases remanded to the state court in Memphis, Tennessee, where 




                                       11
<PAGE>   15

they were originally filed when it was determined that the federal court lacked
jurisdiction over their claims. A number of plaintiffs have failed to pursue
claims made on their behalf and their claims were dismissed without prejudice.
As of March 31, 1998, the claims of approximately 1,000 plaintiffs remain active
in the litigation pending in Memphis, Tennessee. The presiding state court judge
in Memphis has established a case management plan which calls for the
preparation of eight representative cases for preparation and trial.

Discovery is proceeding in all remaining state court cases. Some state cases
have been given trial dates in 1998. It is anticipated that a number of other
state court cases around the country may be scheduled for trial in 1998,
although delays in trial dates are common. Trials in the Memphis proceedings are
scheduled to begin in 1998.

ACROMED CORPORATION SETTLEMENT

In December 1996, AcroMed Corporation ("AcroMed"), a spinal implant manufacturer
and a defendant in many of the cases pending in the Multidistrict Litigation,
and the Plaintiff's Legal Committee in the Multidistrict Litigation announced
that they had entered into a conditional settlement regarding all product
liability claims involving the use of AcroMed devices to achieve pedicular
fixation with screws in spinal fusion surgery. Under the terms of the
settlement, AcroMed will establish a settlement fund consisting of $100 million
in cash plus the proceeds of its product liability insurance policies. In
January 1997, the parties submitted a formal class settlement agreement and
related documentation for approval by Judge Bechtle. By order dated October 17,
1997, Judge Bechtle certified the proposed settlement class and approved the
proposed settlement. All federal and court proceedings involving AcroMed devices
have been stayed pending final jurisdictional consideration of the proposed
settlement.

INSURANCE

Several insurance carriers have asserted reservation of rights concerning the
scope and timing of the Company's remaining insurance coverage, but have not
denied insurance coverage by the Company. Three of the carriers, Royal Surplus
Lines Insurance Company ("Royal"), Steadfast Insurance Company ("Steadfast") and
Agricultural Excess and Surplus Insurance Company ("Agricultural"), have each
filed declaratory judgment actions against the Company seeking clarification of
their rights and obligations, if any, under their respective policies. Neither
Royal nor Agricultural has paid amounts due to the Company; Steadfast has paid
only a portion of the amounts due to the Company.

The Royal and Steadfast lawsuits are pending in the United States District Court
for the Western District of Tennessee in Memphis. The Agricultural lawsuit is
pending in the United States District Court for the Southern District of Ohio in
Cincinnati. The Company believes that the receivables are recoverable under the
terms of the Royal, Steadfast and Agricultural policies. The Company has filed
an answer and counterclaim in the Royal litigation and a motion seeking the
interim payment of the Company's defense costs. The Company has filed an answer
and counterclaim in the Steadfast litigation and intends to file an answer and
counterclaim in the Agricultural litigation. These litigations are in the
preliminary stages. The Company believes that Royal's, Steadfast's and
Agricultural's claims are without merit and will defend against them vigorously.

As is common in the insurance industry, the Company's insurance policies
covering product liability claims must be renewed annually. Although the Company
has been able to obtain insurance relating to product liability claims at a cost
and on other terms and conditions that are acceptable to the Company, there can
be no assurance that in the future it will be able to do so.

On January 6, 1997, the Company announced that its 1996 financial results would
include a pre-tax charge of $50 million relating to costs associated with the
product liability litigation described above. The charge, which is reflected in
the Company's 1996 financial statements, covers the reasonable foreseeable costs
that the Company was positioned in late December 1996 to estimate because the
litigation had progressed and because changes in the fourth quarter of 1996 had
occurred in facts and circumstances relating to the litigation. Among the
changed facts 




                                       12
<PAGE>   16

and circumstances were the announcement of the AcroMed settlement described
above, the likelihood that the litigation will continue for several years, in
part, due to the additional financial resources provided to the plaintiff's
attorneys as a result of the AcroMed settlement, the absence of AcroMed as a
member of the joint defense group, the status of the Company's insurance
described above and the continuing absence of dispositive rulings relating to
the Company's defense motions.

While it is not possible to accurately predict the outcome of litigation, the
accrued liability which remained on the Company's consolidated balance sheet at
December 31, 1997 represents the Company's best judgment of the probable
reasonable costs (in excess of amount of insurance the Company believes are
recoverable) to defend and conclude the lawsuits based on the facts and
circumstances currently existing. The costs provided for in the accrued
liability include, but are not limited to, legal fees paid or anticipated to be
paid and other costs related to the Company's defense and conclusion of these
matters.

The actual costs to the Company could differ from the estimated charge and will
be dependent upon a number of factors that will not be known for some time,
including, among other things, the resolution of defense motions and the extent
of further discovery. Although an adverse resolution of lawsuits could have a
material effect on the Company's results of operations and cash flows in future
periods, the Company does not believe that these matters will in the future have
a material adverse effect on its consolidated financial position. The Company is
unable to predict the ultimate outcome or the financial impact of the product
liability litigation.

SECURITIES LAWS ACTIONS

Beginning in April 1994, the Company and four of its officers and directors were
named in five shareholder lawsuits filed in the United States District Court in
Memphis, Tennessee. Four of the lawsuits purported to be class actions. All of
the lawsuits were consolidated into one case in the United States District Court
in Memphis through an amended complaint which added four new individual
defendants who are either current or former directors of the Company. The
lawsuit alleges that the defendants made false and misleading statements and
failed to disclose material facts to the investing public and seeks money
damages. The alleged securities law violations are based on the claim that the
defendants failed to disclose that Company sold its products illicitly,
illegitimately and improperly and to timely disclose facts concerning the
termination of the former U.S. distributor of Sofamor products, National Medical
Specialties, Inc. ("NMS"). The allegations relating to illicit and illegitimate
sales of product are, for the most part, copies from product liability
complaints filed against the Company and other manufacturers currently being
coordinated in improper sales related to one of the Company's selling programs
which has been publicly disclosed since May 1991. The allegations concerning NMS
relate to the termination of the NMS distribution agreement covering Sofamor
products in the United States. On October 3, 1995, the United States District
Court Judge in Memphis dismissed with prejudice the entire case against the
Company and each of the individual defendants. The plaintiffs appealed the
dismissal to the United States Court of Appeals for the Sixth Circuit. On August
14, 1997, the Court of Appeals affirmed the dismissal of the plaintiffs'
complaint. The Court of Appeals denied the plaintiffs' request for
reconsideration on October 9, 1997. The plaintiffs have filed a petition for
certiorari in the United States Supreme Court.

The Company does not believe the Securities Laws Actions will have a material
adverse effect on its consolidated financial position, results of operations or
cash flows because of, among other reasons, the facts and circumstances existing
with respect to each action, the Company's belief that these actions are without
merit, certain defenses available to the Company and the availability of
insurance in the Securities Laws Actions.

</TABLE>

RESULTS OF OPERATIONS

Years ended December 31, 1997 and 1996

The Company reported revenues for 1997 of $312.9 million, which represented a
$68.4 million, or 28.0%, increase over 1996 revenues of $244.5 million. The
record 1997 revenues reflect the Company's position as the leader in providing
products to treat spinal disorders. Increased volume generated growth of 26.1%.
Revenues were higher by 3.6% due to net changes in pricing and by 2.0% as a
result of the Company's conversion of certain portions of its international
distribution network to direct sales which resulted in higher selling prices. If
exchange rates had been constant, revenues would have reflected an additional
3.7% increase compared with the prior year.

U.S. revenues increased 30.3% to $211.4 million compared with $162.2 million in
1996. The Company believes the improvement in U.S. revenues is primarily the
result of the increasing number of instrumented spinal fusions. The increase in
the number of instrumented fusions has occurred, in part, due to the broad range
of quality spinal products provided by the Company to assist physicians in
treating their patients. In addition to this broad range of implant products,
the Company is benefiting from offering complimentary product technologies
including the STEALTHSTATION(TM) system, the MedNext(R) surgical drill system
and the MED(TM) system. The Company has also benefited from service fees related
to cortical bone dowel and other allograft bone products.

Non-U.S. revenues advanced 23.4% to $101.5 million compared with $82.3 million
in 1996. If exchange rates had been constant, the international revenue growth
over 1996 would have been 34.4%. Higher sales volume in core products and the
acceptance of new products were the primary sources of the increase in revenues
over the prior year. In addition, the Company's revenues continued to benefit
from the direct sales operations which were established in selected countries
during 1996 and 1997.





                                       19
<PAGE>   23

The Company's gross margin was 81.4% in 1997 compared with 81.6% in 1996. The
slight decrease was primarily attributable to the effects of changes in product
mix.

Selling, general and administrative ("SG&A") expenses expressed as a percentage
of revenues decreased to 46.4% in 1997 compared with 47.7% in 1996. The decrease
in SG&A expenses as a percentage of revenues resulted from the leveraging of
fixed costs over greater revenue volume, despite higher expenses incurred in
direct sales operations established in selected countries during 1996 and 1997.

Research and development expenses totaled $19.7 million, or 6.3% of revenues, in
1997 compared with $15.9 million, or 6.5% of revenues, in 1996. The 1997 dollar
spending represented an increase of 24.0% over 1996. These development and
clinical costs are incurred as the Company continues to enhance existing product
lines and develop new and complementary products, such as the interbody fusion
devices, biological products for use in spinal applications, and products
related to frameless stereotactic surgery in the spinal and neurological fields
of use.

During 1996, the Company recorded a special product liability litigation charge
of $50.0 million. This charge was recorded in order to recognize the reasonably
anticipated costs associated with the defense and conclusion of certain product
liability cases in which the Company is named as defendant. No such charge was
recorded in 1997. The Company believes that these lawsuits are without merit and
unfounded. (See Note 14 to the Consolidated Financial Statements.)

The Company reported net other income of $5,000 in 1997 compared with $913,000
during 1996. Other income was higher during 1996 due mainly to foreign exchange
gains. Interest expense was $5.5 million in 1997, representing a $1.8 million
increase over 1996. Interest expense was higher during 1997 due to interest on
increased borrowings under the Company's credit facilities occurring principally
as a result of acquisitions made in 1996.

The Company recorded income tax expense of $25.1 million in 1997 and $1.3
million in 1996. The difference between the Company's effective and statutory
tax rates for both 1997 and 1996 resulted primarily from the impact of certain
elections made for U.S. tax purposes following the combination (the
"Combination") of Danek Group, Inc. with Sofamor S.A., and the subsequent
reorganization of Sofamor S.A. from a Societe Anonyme (S.A.) under French law to
a Societe en Nom Collectif (S.N.C.) in late 1993. Management cannot be certain
that such a favorable effective income tax rate will be achieved in future
periods, since the effective tax rate calculation is dependent upon the
Company's pre-tax income dollar amount. Higher future pre-tax income could lead
to higher future effective tax rates. At December 31, 1997, the balance sheet of
the Company reflected a net deferred tax asset of $39.4 million. No valuation
allowance was recorded since sufficient taxable income exists in available
carryback periods to recognize fully these net deferred tax assets. (See Note 11
to the Consolidated Financial Statements.)

Minority interest was $2.3 million in 1997 compared with $1.5 million in 1996.
The increase was primarily related to the existence of a minority interest for a
full year in the Company's Korean subsidiary which was formed in November 1996.

The Company believes that historically inflation has not had a material impact
on its business.

Years ended December 31, 1996 and 1995

The Company achieved record revenues during 1996 of $244.5 million, which
represented a $55.7 million, or 29.5%, increase over revenues of $188.8 million
in 1995. Revenue growth included an increase of 8.5% that resulted from the
conversion of certain portions of the Company's international distribution
network to direct sales, which resulted in higher selling prices. Other net
pricing changes in existing distribution channels resulted in a 




                                       20
<PAGE>   24

3.9% increase in revenues. Additional volume comprised the remainder of the
increase in revenues. Changes in exchange rates had an immaterial impact on
revenues when comparing the Company's 1996 revenues with 1995.

U.S. revenues increased 28.4% to $162.2 million, as compared with $126.3 million
in 1995. The Company believes the improvement in U.S. revenues was primarily the
result of an increased number of instrumented fusions, as well as the acceptance
of new products such as the STEALTHSTATION(TM) system, the TiMesh(TM) cranial
plating system and the MedNext(R) surgical drill system.

Non-U.S. revenues increased 31.7% to $82.3 million, as compared with $62.5
million in 1995. The strong international revenue growth during 1996 reflects
the Company's strategy of establishing a direct sales presence in selected
countries and the acceptance of the new products mentioned in the preceding
paragraph, as well as enhanced international sales and marketing programs.

The Company's gross margin improved to 81.6% in 1996 from 78.6% in 1995. The
enhancement in gross margin is due to higher margins relating to changes in
international distribution, greater leveraging of manufacturing costs due to
increased volume, a reduction in the levels of outsourced product manufacturing
and favorable shifts in the sales mix of certain products and sales programs.

SG&A expenses were 47.7% of revenues in 1996 compared with 47.6% of revenues in
1995. The 1996 SG&A expenses as a percentage of revenues compared to 1995 were
slightly higher due to the effects of expenses related to establishing a direct
sales presence in selected countries. These higher expenses were mostly offset
by the leveraging of other fixed costs over greater volume in existing
operations.

Research and development expenses totaled $15.9 million or 6.5% of revenues in
1996 compared with $14.0 million or 7.4% of revenues in 1995. The 1996 dollar
spending represented an increase of 13.9% over 1995. These costs were incurred
as the Company continued to enhance existing product lines and develop new and
complementary products for use in spinal surgery, such as interbody fusion
devices, biological products for use in spinal reconstruction and products
related to frameless stereotactic surgery in the spinal and neurological fields
of use.

During 1996, the Company recorded a special product liability litigation charge
of $50.0 million. This charge was recorded in order to recognize the reasonably
anticipated costs associated with the defense and conclusion of certain product
liability cases in which the Company is named as defendant. The Company believes
that these lawsuits are without merit and unfounded. (See Note 14 to the
Consolidated Financial Statements.)

In 1995, the Company entered into a strategic alliance with Genetics Institute
to provide biological products for use in spinal applications (the "G.I.
Agreement"). Pursuant to the G.I. Agreement, the Company obtained exclusive
North American rights to recombinant human bone morphogenetic protein (rhBMP-2)
for spinal applications. As a result of the G.I. Agreement, a special charge of
$45.3 million was recorded. The special charge consisted of $45.2 million, which
represented the net present value of the $50.0 million in scheduled payments due
under the agreement, plus related transaction costs of $122,000. The charge
resulted in an after-tax impact of $1.16 per diluted share for the year ended
December 31, 1995.

The Company reported net other income of $913,000 in 1996 compared with $2.5
million during 1995. Other income was higher during 1995 due mainly to the
reversal of certain risk provisions and greater foreign exchange gains. Interest
expense was $3.7 million in 1996, representing a $950,000 increase over 1995.
The increase in interest expense was due to increased borrowings under the
Company's credit facilities occurring principally as a result of the
acquisitions made during 1996.

The Company recorded income tax expense of $1.3 million in 1996 and an income
tax benefit of $6.3 million in 1995. The difference between the Company's
effective and statutory tax rates for both 1996 and 1995 resulted 




                                       21
<PAGE>   25

primarily from the impact of certain elections made for U.S. tax purposes
following the Combination of Danek Group, Inc. with Sofamor S.A., and the
subsequent reorganization of Sofamor S.A. from an S.A. under French law to an
S.N.C. in late 1993.

Minority interest was $1.5 million in 1996 compared with $417,000 in 1995. The
increase was principally due to the minority interest in the Company's Japanese
subsidiary which was formed in February 1996.

LIQUIDITY AND CAPITAL RESOURCES

On January 26, 1998, the Company purchased all of the outstanding capital stock
of SOFYC, S.A. ("SOFYC") for an aggregate of 2,806,080 privately placed shares
of the Company's Common Stock, $1.0 million in cash (less certain expenses
relating to the repurchase) and the Company's agreement to repay certain
outstanding loans of SOFYC equal to approximately $925,000 (the "SOFYC
Exchange"). SOFYC, which was the personal holding company of the Cotrel family,
owns 3,337,272 shares of the Company's Common Stock. As a result of the SOFYC
Exchange, the outstanding shares of Common Stock of the Company will be reduced
by 531,192 shares. In connection with the transaction, certain registration
rights were granted to SOFYC shareholders. In accordance with these rights, the
Company filed a registration statement with the Securities and Exchange
Commission relating to a proposed public offering on behalf of the former SOFYC
holders of 1,600,000 of their 3,689,711 shares of Sofamor Danek common Stock
that they own in the aggregate. The registration statement also includes a
proposed public offering of up to 1,200,000 shares of common stock to be sold by
Sofamor Danek for its own account. In addition, Sofamor Danek will grant to the
underwriters an over-allotment option relating to a maximum of 420,000 shares of
common stock.

Cash generated from operations and the Company's revolving lines of credit are
the principal ongoing sources of funding available for growth of the business,
including working capital and additions to property, plant and equipment, as
well as debt service requirements and required contractual payments. The Company
believes that these sources of funding together with the proceeds from the
Offering will be sufficient to meet its expected cash needs for the foreseeable
future. Cash, cash equivalents and short-term investments totaled $2.8 million
at December 31, 1997, compared with $2.9 million at December 31, 1996.

The Company's working capital increased by $91.9 million during 1997. The
increase in working capital resulted primarily from the renegotiation of the
Company's $100.0 million uncollateralized revolving line of credit with a
syndicate of U.S. banks which extended the maturity thereof from October 1997 to
July 2000 (see Notes 8 and 9 to the Consolidated Financial Statements) as well
as the effects of operating activities. Accounts receivable increased $18.2
million or 26.0% from December 31, 1996, due principally to the 30.2% increase
in revenues in the fourth quarter of 1997 compared with the last quarter of
1996. Inventories and loaner set inventories increased by $14.5 million from
prior year, due mostly to stocking levels required for recently formed
subsidiaries and the production of inventories in preparation for new sales and
marketing programs. Other receivables, which consisted primarily of amounts
recoverable from insurance carriers related to the costs incurred in connection
with product liability litigation (see Note 14 to the Consolidated Financial
Statements), increased $13.6 million from the previous year-end.

In connection with the formation of its subsidiary in Japan, Kobayashi Sofamor
Danek, K.K. ("KSD"), the Company is required to pay commissions based on the
sales of KSD to Kobayashi Pharmaceutical Co., Ltd. ("KPC"), which has served as
the Company's distributor in Japan and is the other shareholder in KSD. Payments
of $2.0 million and $26.7 million in 1997 and 1996, respectively, were made to
KPC as prepayments of commissions.

In connection with the G.I. Agreement, the Company has a liability of $7.0
million at December 31, 1997. This liability represents the initial present
value of the remaining $7.5 million payment due in June of 1998 under the
agreement. Under this agreement, payments of $17.5 million, $12.5 million and
$12.5 million were made in 1997, 1996 and 1995, respectively.






                                       22

The purchase agreements for two acquisitions made by the Company in 1996 contain
provisions which provide for contingent payments to the former shareholders of
each entity based upon certain calculations relative to revenues and earnings,
as defined, through 1999. Such payments are reflected as purchase price
adjustments. The Company recorded adjustments to the purchase price of these
acquisitions of $5.1 million and $4.2 million in 1997 and 1996, respectively.
The amount recorded in 1996 was paid in April 1997, and the amount recorded in
1997 is expected to be paid in March 1998. The Company is unable to determine
whether such adjustments will be required for 1998 or 1999.

Additions to property, plant and equipment amounting to $10.3 million, $7.1
million and $4.6 million in 1997, 1996 and 1995, respectively, were made
primarily relating to capital assets acquired in the formation and acquisition
of new subsidiaries and other capital expenditures necessary to support the
Company's manufacturing and distribution operations. The Company is in need of
additional office and distribution space at its Memphis location. Management has
entered into an agreement whereby the Company will lease, with an initial term
of 10 years, a new facility adjacent to its existing headquarters with an
expected occupancy date of mid 1998. This lease will be accounted for as an
operating lease.

The Company has committed lines of credit totaling $115.9 million. At December
31, 1997, $67.3 million was outstanding under these lines of credit and other
short-term borrowings. The committed lines of credit consist primarily of the
$100.0 million U.S. revolving line of credit.

In 1996, the Internal Revenue Service began an examination of the Company's
federal income tax returns. The years under examination are 1993, 1994 and 1995.
Management believes that the resolution of any issues that may be developed as a
result of the examination will not have a significant impact on the Company's
results of operations or financial condition.

The Company invests available funds in short-term investment grade instruments,
certificates of deposit or direct or guaranteed obligations of the United States
of America. These short-term investments are available to fund the Company's
working capital requirements and acquisitions of capital assets.

The "Year 2000" issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Any computer programs
that have time sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000. This could result in a system failure or
miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices or engage
in similar normal business activities. Management has conducted an assessment of
its exposure to disruption associated with the "Year 2000" issue. The Company is
currently in the process of implementing purchased software that will serve as
an enterprise resource planning system providing enhanced productivity and
customer service benefits in addition to mitigating potential consequences of
the Year 2000 issue. The cost of the software license and the majority of the
costs of implementation will be capitalized. Management expects this
implementation to be complete by the end of 1998. The Company believes that with
modifications to existing software and conversions to new software, the Year
2000 issue will not pose significant operational problems for its computer
systems. However, if such modifications are not made, or are not completed in a
timely manner, the Year 2000 issue could have an impact on the Company's ability
to operate. The Company does not believe that the costs of addressing this issue
will be material to the Company's operations.

FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS AND FINANCIAL CONDITION

The Company's future operating results and financial condition are subject to
risks and uncertainties, including (without limitation) the following matters:





                                       23
<PAGE>   27

Regulatory Clearances and Compliance. The preclinical testing, manufacturing,
labeling, distribution and promotion of the Company's products are subject to
extensive government regulation by the FDA in the United States and comparable
regulatory bodies in other countries. Noncompliance with the applicable
regulatory requirements can lead to enforcement action which may result in,
among other things, warning letters, fines, recall or seizure of products, total
or partial suspension of production, refusal by governments to grant pre-market
clearances and criminal prosecution. The process of obtaining marketing
clearances can be time-consuming, and there can be no assurance that all
necessary clearances will be granted to the Company with respect to new devices
or that the process will not involve delays adversely affecting the marketing
and sale of new devices. In the United States, even after regulatory clearance
or approval to market a device is obtained from the FDA, the Company is subject
to continuing FDA regulation. FDA approvals are required for new intended uses
and certain changes to a marketed device. FDA regulations depend heavily on
administrative interpretation, and there can be no assurance that future
interpretations made by the FDA or other regulatory bodies, with possible
retroactive effect, will not adversely affect the Company. The Company is also
subject to numerous federal, state and local laws relating to such matters as
safe working conditions, manufacturing practices and environmental protection.
There can be no assurance that the Company will not be required to incur
significant costs to comply with such laws and regulations. Unanticipated
changes in existing regulatory requirements, failure of the Company to comply
with such requirements or adoption of new requirements could have a material
adverse effect on the Company's business.

Potential Impact of Healthcare Cost Containment Proposals on Profitability.
Sales of a large portion of the Company's products depend to a significant
extent on the availability of reimbursement to the Company's customers by
government and private insurance plans. In recent years, the cost of healthcare
has risen significantly, and there have been numerous proposals by legislators,
regulators and third party health care payers to curb these cost increases in
the United States and Europe. Some of these proposals have involved limitations
on the amount of reimbursement for specific surgical procedures. These proposals
have been adopted in some cases. The Company is unable to predict the ultimate
timing, scope or effect of any legislation concerning healthcare reform. Any
legislation, if adopted, could result in significant changes in the
availability, delivery, pricing and payment for healthcare services and products
and adversely affect the Company's business. In addition, hospitals and other
healthcare providers have become increasingly cost sensitive. To date, the
Company does not believe that such healthcare cost containment proposals have
negatively affected the profitability or growth of its business; however, the
Company is not able to predict the future effect of these proposals on its
business.

Rapid Technological Change; Technological Obsolescence; Acceptance Of New
Products. The medical device industry is characterized by rapidly changing
technology and frequent new product introductions. The Company's future success
will depend largely on the Company's ability to develop and introduce in a
timely manner new products and enhancements that meet changing customer
requirements and emerging industry standards. Although the Company's strategy
for growth includes the introduction of new products, the development of new
technologically advanced products and enhancements is a complex and uncertain
process requiring high levels of innovation as well as the anticipation of
technology and market trends. The Company may not be able to respond effectively
to technological changes, emerging industry standards or product announcements
by competitors, it may not be able to identify, develop, manufacture, market,
sell or support new products and enhancements successfully and its new products
or enhancements may not achieve market acceptance. Market acceptance for
products under development could be adversely affected by numerous factors,
including the lack of availability of third-party reimbursement to consumers of
such products, the cost of the products, clinical acceptance thereof and
effective physician training. Market acceptance will also depend on the
Company's ability to demonstrate that such products are an attractive
alternative to existing products, which will depend on physicians' evaluations
of the clinical safety and efficacy, ease of use, reliability and
cost-effectiveness of the products. Furthermore, the Company believes that, once
the products receive approval, recommendations and endorsements by influential
surgeons will be essential to market acceptance of its products. There can be no
assurance that the Company's products under development will adequately
demonstrate these characteristics or that they will receive market acceptance
among consumers or physicians. Any of these events could have a material adverse
effect on the Company's business, financial condition and results of operations.

Product Liability; Insurance. In recent years, physicians, hospitals, and other
participants in the healthcare industry have become subject to an increasing
number of lawsuits alleging malpractice, product liability or related legal
theories, many of which involve large claims and significant defense costs. The
Company is currently involved in product liability litigation. (See Note 14 to
the Consolidated Financial Statements.) There can be no assurance that
additional claims will not be asserted against the Company in the future. A
successful future claim or aggregation of future claims brought against the
Company in excess of insurance coverage could have a material adverse effect
upon the financial condition, results of operations and/or cash flows of the
Company. Claims against the Company, regardless of their merit or eventual
outcome, may also have a material adverse effect upon the reputation and
business of the Company. The Company currently maintains liability insurance at
coverage levels which it deems commercially reasonable. Historically, the
Company has been required to call on its insurance for product liability claims,
and assuming all amounts are paid by the insurance carriers, the Company will
have exhausted its insurance coverage for the coverage year ended November 1995.
There can be no assurance that the coverage limits of such insurance policies
will be adequate or that all amounts will ultimately be collected from each
insurer providing the applicable policy. Such insurance is expensive, difficult
to obtain and may not be available in the future on acceptable terms or at all.

Increasing Competition. The medical device industry is subject to intense
competition. The market for products designed to treat spinal conditions is
highly competitive, and the Company expects competition to increase as a result
of new entrants and consolidations. Accordingly, the Company's future success
will depend in part on its ability to respond quickly to medical and
technological change and user preferences through the development and
introduction of new products that are of high quality and that address patient
and surgeon requirements and, in part, on its ability to differentiate its
mature products from those of its competitors. Worldwide, there are many firms
producing spinal implant devices, and certain of the Company's competitors
currently manufacture and sell interbody fusion cages that have received a PMA
from the FDA. A number of these firms have greater financial, research and
development, manufacturing and sales and marketing resources than the Company.
The Company's inability to compete effectively against existing or future
competitors would have a material adverse effect on its business, financial
condition and results of operations.

Dependence On Key Personnel. The Company's future success depends in significant
part upon the continued service of certain key scientific, technical and
managerial personnel and its continuing ability to attract and retain highly
qualified scientific, technical and managerial personnel. Competition for such
personnel is intense, and there can be no assurance that the Company can retain
its current personnel or that it can attract, assimilate or retain other highly
qualified scientific, technical and managerial personnel in the future. The
Company has taken steps to retain its key employees, including the granting of
stock options that vest over time. The loss of key personnel, especially if
without advanced notice, or the inability to hire or retain qualified personnel
could have a material adverse effect upon the Company's business, financial
condition and results of operations.

Risks Associated With International Sales. A significant portion of the
Company's revenues relate to international sales of its products, which are
subject to numerous risks. Regulatory requirements, as well as pricing,
marketing and distribution structures, vary significantly from country to
country. Additionally, international sales can be adversely affected by
limitations or disruptions caused by the imposition of government controls,
export licenses, political instability, trade restrictions, changes in foreign
tax laws or tariffs, or other trade regulations and difficulties coordinating
communications among and managing international operations. Moreover, the
Company's business, financial condition and results of operations may be
adversely effected by fluctuations in overseas economic conditions and
international currency exchange rates, as well as by increases in duty rates,
difficulty in obtaining export licenses, constraints on its ability to maintain
or increase prices and competition. There can be no assurance that the Company
will be able to successfully commercialize its existing products or any of its
future products in any international market, which could have a material adverse
effect on the Company's business, financial condition and results of operations.






                                       25
<PAGE>   29

Dependence On Patents And Proprietary Technology. The patent and trade secret
positions of medical device companies, including those of the Company, are
uncertain and involve complex and evolving legal and factual questions. The
coverage sought in a patent application either can be denied or significantly
reduced before or after the patent is issued. Consequently, there can be no
assurance that any patents from pending applications or from any future patent
application will be issued, that the scope of the patent protection will exclude
competitors or provide competitive advantages to the Company, that any of the
Company's patents will be held valid if subsequently challenged or that others
will not claim rights in or ownership of the patents and other proprietary
rights held by the Company. Since patent applications are secret until patents
are issued in the United States, or corresponding applications are published in
other countries, and since publication of discoveries in the scientific or
patent literature lags behind actual discoveries, the Company cannot be certain
that it was the first to file patent applications for its inventions. In
addition, there can be no assurance that competitors, many of which have
substantial resources, will not seek to apply for and obtain patents that will
prevent, limit or interfere with the Company's ability to make, use or sell its
products either in the United States or in international markets. Further, the
laws of certain foreign countries do not protect the Company's intellectual
property rights to the same extent as do the laws of the United States.
Litigation or regulatory proceedings, which could result in substantial cost and
uncertainty to the Company, may also be necessary to enforce patent or other
intellectual property rights of the Company or to determine the scope and
validity of other parties' proprietary rights. There can be no assurance that
the Company will have the financial resources to defend its patents from
infringement or claims of invalidity.

The Company also relies upon unpatented proprietary technology, and no assurance
can be given that others will not independently develop substantially equivalent
proprietary information and techniques or otherwise gain access to or disclose
the Company's proprietary technology or that the Company can meaningfully
protect its rights in such unpatented proprietary technology. The Company's
policy is to require each of its key employees, consultants, investigators and
advisors to execute a confidentiality agreement upon the commencement of an
employment or consulting relationship with the Company. There can be no
assurance, however, that these agreements will provide meaningful protection for
the Company's proprietary information in the event of unauthorized use or
disclosure of such information.

Dependence On Suppliers. The Cortical Bone Dowel, a product the Company
distributes on behalf of the University of Florida Tissue Bank ("UFTB"), is made
of human bone tissue obtained from cadavers. The UFTB supplies significant
amounts of such tissue pursuant to an exclusive agreement with the Company.
There can be no assurance that the supply of bone tissue will continue to meet
current demand, or that the Company, if required, will be able to locate
alternative sources of human bone tissue on a timely and cost-effective basis.
To date, constrained supply of human bone tissue has limited growth in this
area. There can be no assurance that the UFTB will meet the Company's future
delivery requirements of human bone tissue. The inability to procure an adequate
supply of such tissue could have a material adverse effect on the Company's
business, financial condition and results of operations.

AMENDED AND RESTATED EMPLOYMENT AGREEMENT, dated as of 13 day of April, 1997,
between SOFAMOR DANEK GROUP, INC., an Indiana oration (the "Employer"), and
Laurence Fairey (the "Employee").

                                    RECITALS

         WHEREAS, the Employer is an Indiana corporation and through its wholly
owned subsidiaries, Warsaw Orthopedic, Inc., Danek Medical, Inc., and Sofamor,
S.N.C. is engaged in the business of developing, manufacturing and distributing
medical devices, trauma instruments, surgical tools and implants (such business,
as it may change from time to time, is hereinafter refer-red to as "Business");
and

         WHEREAS, the Board of Directors of the Employer (the "Board") has
concluded that it desires to retain the valued services of the Employee by
entering into a new agreement which shall provide the Employee with certain
additional protections which are designed to ensure that the Employee will
devote himself attentively and energetically to his duties without distraction:

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants contained herein the parties agree as follows:

         1. Employment. The Employer (or a subsidiary of the Employer) hereby 
employs the Employee and the Employee hereby accepts employment upon the terms
and conditions hereinafter set forth,

         2. Term. Subject to the provisions for termination as provided in
paragraph 10 hereof, the term of this Agreement shall be from April 13, 1997 to
December 31, 1999, and it shall be automatically renewed for successive one (1)
year periods thereafter, unless either party elects not to renew this Agreement
by serving notice of such intention not to renew on the other party at least
ninety (90) days prior to the renewal date. Notwithstanding the foregoing, if a
Change in Control Date (as defined in paragraph 11) occurs during the term
described in the immediately preceding sentence, the term of the Employee's
employment hereunder shall extend until the third anniversary of such Change in
Control Date (the period beginning on such Change in Control Date and ending on
the third anniversary thereof being hereinafter referred to as the "Covered
Period").

         3. Duties. The Employee is engaged as Executive Vice President and
Chief Financial Officer of the Employer to assist the President and CEO of the
Employer in managing, directing and administering all aspects and matters of the
Business, subject to the direction and guidance of the President and CEO of the

<PAGE>   3

and Chief Financial Officer of the Employer may be further defined, extended or
curtailed from time to time at the discretion of the President and CEO of the
Employer.

         4. Extent of Services. The Employee shall have the power and authority
commensurate and necessary to his position of Executive Vice President and Chief
Financial Officer and his other duties as assigned to him from time to time. He
shall devote his entire employable time, attention and best efforts to the
Business as may be necessary to efficiently and effectively perform and complete
the duties he is to undertake as described in this Agreement. The Employee shall
not, without the consent of the Employer, which consent shall not be
unreasonably withheld, during the term of this Agreement, be actively engaged in
any other business activity, whether or not such business activity is pursued
for gain, profit and other pecuniary advantage; but this shall not be construed
as preventing the Employee from investing his personal assets in such form or
manner as will not require any services on the part of the Employee in the
operation of the affairs of the companies in which such investments are made.

         5. Compensation. The Employee shall be compensated for services
rendered hereunder as follows:

         (a) The Employee shall receive a salary of not less than $19,167 per
month for each month of the first twelve (12) months that this Agreement is in
effect and for each month thereafter so long as the Employee receives Job
Performance Evaluations of "good" or better. After such first year, if the
Employee receives a Job Performance Evaluation of less than "good", his salary
shall be determined in the discretion of the President and CEO of the Employer.
Such salary paid to the Employee shall be subject to withholding of taxes and
other appropriate and customary amounts.

         (b) The Employee shall be entitled to participate in the employee
benefit plans the Employer may adopt from time to time for its management or
supervisory personnel generally at such time as the Employee shall have
fulfilled the eligibility requirements for participation therein as shall be
determined by the terms of the applicable contracts for each program. Nothing
herein shall be construed so as to prevent the Employer from modifying or
terminating any employee benefit plans or programs or employee fringe benefits
it currently sponsors or may adopt from time to time.

         6. Expenses and Travel. It is expected that in the course of his
employment, the Employee and his spouse shall be required to spend time

Employee an Employer Mastercard credit card or the Employer shall pay the
Employee the annual fee for one (1) personal credit card. The Employer shall pay
for or reimburse the Employee for all such reasonable expenses upon the
Employee's periodic presentation of an itemized account of such expenditures,
provided, however, the Employer shall only pay for or reimburse for the cost of
coach class air fare for business travel within the United States and only for
the cost of business class air fare for international business air travel. The
Employer shall bear the expense, in an amount not to exceed $250 per month, for
country club or social club dues for which the Employee may become a member
during the term hereof and/or a
<PAGE>   4
portable telephone and related telephone service, the use of either of which is
related to the Business. The Employee shall bear the expense of any initiation
fees and other assessments for or resulting from such membership. The Employee
shall be reimbursed in an amount not to exceed a total of $2,000 for each year
during the term or any renewal term hereof, for expenses incurred for his spouse
when traveling with the Employee on business matters for the Employer.


         7. Disability. If the Employee shall become physically or mentally
disabled during the term of this Agreement to the extent that he shall be unable
to perform his duties and services for and on behalf of the Employer, the
benefits made available to the Employee and the salary then payable to the
Employee pursuant to the foregoing paragraph 5 shall continue to be made
available and paid to the Employee for the shorter of (i) the period of
disability; or (ii) six (6) months from the commencement of the disability.
Thereafter, the Employee shall receive no salary from the Employer.

         8. Confidentiality. The Employee possesses and will continue to possess
information which has been created, discovered, developed by or otherwise become
known to the Employee (including information discovered or made available by
subsidiaries, affiliates or joint ventures of the Employer or in which property
rights have been assigned or otherwise conveyed to the Employer), which
information has commercial value to the Employer, including but not limited to
trade secrets, innovations, processes, computer codes, data, know-how,
improvements, discoveries, developments, techniques, marketing plans,
strategies, costs, customer and client lists, or any information the Employee
has reason to know the Employer would treat as confidential for any purpose,
whether or not developed by the Employee (hereinafter referred to as
"Confidential Information"). Unless previously authorized in writing or
instructed in writing by the Employer, the Employee will not, at any time,
disclose to others, or use, or allow anyone else to disclose or use any
Confidential Information (except as may be necessary in the performance of the
Employee's employment with the Employer), unless, until and then only to the
extent that such Confidential Information has become ascertainable or obtained
from public or published sources or was available to the Employee on a
non-confidential basis prior to any such disclosure or use, provided that the
source of such material is or was not bound by an obligation of confidentiality
to the Employer. This paragraph 8 shall survive termination of this Agreement.

         9. Restrictive Covenants. The terms of this paragraph 9 shall be
applicable during the Employee's employment and upon the termination of such
employment for any reason occurring prior to a Change in Control Date. In the
event of termination it without cause" as defined in paragraph 10(b) occurring
prior to a Change in Control Date, in consideration of, and subject to, the
Employee's continued compliance with the terms of this paragraph 9, the Employer
shall pay to the Employee twelve (12) months salary based on his salary for the
month immediately preceding the date of termination which shall be paid in
accordance with the Employer's customary payroll practices over twelve (12)
months. In the event of a termination for any other reason, including for "just
cause" as defined in paragraph 10(b) occurring prior to a Change in Control
Date, the Employer shall have no obligation to the Employee, This paragraph 9
shall survive termination of this Agreement occurring prior to a Change in
Control Date.

         The Employee acknowledges that because of his skills, the Employee's
position with the Employer and the Confidential Information to which the
Employee shall have access or be provided on account of such employment with the
Employer, competition by the Employee with the Employer could damage the
Employer in a manner which cannot adequately be compensated by damages or an
action at law. In view of such circumstances, because of the Confidential
Information obtained by, or disclosed to the Employee, and as a material
inducement to the Employer to enter into this Agreement and to compensate the
Employee, as described in paragraph 5, as well as provide him with additional
benefits as provided herein and other good and valuable consideration, the
Employee covenants and agrees that:

         (a) Noncompetition. During the Employee's employment with the Employer
and for a period of three (3) years thereafter, the Employee shall not (as
principal, agent, employee, consultant or otherwise), directly or indirectly, in
any geographic area in which the Employer is engaged in Business, engage in
activities for, or render services of any nature to. any firm or business, which
firm or business competes. directly or indirectly, with the Employer or the
Business.

         (b) Nonsolicitation of Customers. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit, divert or accept any work or services
which compete with the Employer's Business from any customer of the Employer or
seek to cause any such customer to refrain from doing business with or
patronizing the Employer.

         (c) Nonsolicitation of Employees. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit for employment or employ any current or
former employee of the Employer.

         (d) Definitions. For purposes of this Agreement, the term "directly or
indirectly" shall be construed in its broadest sense and shall include the
activities of the members of the Employee's immediate family or any partnership.
The term "Business" shall be construed in its broadest sense and shall include
any activity engaged in or conducted by the Employer or any of its subsidiaries,
affiliates or joint ventures or which the Employer or any of its subsidiaries,
affiliates or joint ventures intends to engage in or conduct. The term
"customer" shall mean any person or entity with which the Employer, or any of
its subsidiaries, affiliates or joint ventures has engaged in or conducted
Business during the one (1) year period prior to the date the Employee ceased
employment with the Employer or any persons or entities targeted by the Employer
or contacted for the purpose of engaging in or conducting Business during such
one (1) year period.

         (e) Reasonable Limitations. Given the important nature of the position
the Employee will hold with the Employer, the nature of the Employer's Business
and the sensitive nature of the Confidential Information and duties the Employee
will have with the Employer, the parties acknowledge that the limitations,
including but not limited to, the scope of activities prohibited. the geographic
area covered and the time limitation, are reasonable.


<PAGE>   6

         In the event of an actual or threatened breach by the Employee of the
provisions of paragraphs 8 and 9 of this Agreement, the Employer shall be
entitled to a temporary restraining order and an injunction restraining the
Employee from such breach. Nothing herein, however, shall be construed as
prohibiting the Employer from pursuing any other remedies available to it for
such actual or threatened breach, including, without limitation, the recovery of
damages and reasonable attorneys' and paralegals' fees and costs from the
Employee. If the Employee violates any of the covenants in paragraphs 8 and 9 of
this Agreement, the term and the covenant violated shall be automatically
extended for the period of time of the violation, either from the date on which
the Employee ceases such violation or from the date of the entry by a court of
competent jurisdiction of an order or judgment enforcing such covenants.
whichever period is later,

         10. Termination Prior to a Change in Control Date. The Employer may, at
its option, terminate this Agreement at any time prior to the occurrence of a
Change in Control Date upon written notice to the Employee for just cause or
without cause.

         (a)      "Just cause" shall include, but not be limited to:

                  (i)     The Employee receiving a Job Performance Evaluation of
                          less than "good";

                  (ii)    The Employee's misuse or embezzlement of funds
                          belonging to the Employer, conviction of a felony or
                          crime involving moral turpitude or use of alcohol or
                          drugs in such a manner as will injure or adversely
                          affect the reputation of the Employer or its
                          employees, customers, agents, officers or directors,

                  (iii)   The Employee's absence from his employment, for
                          whatever cause, other than by disability for which
                          salary is continued pursuant to paragraph 7, for a
                          period of thirty (30) consecutive days or more;

                  (iv)    The Employee's absence from employment as a result of
                          disability beyond the period for which salary is
                          continued pursuant to paragraph 7;

                  (v)     The Employee's resignation from employment during the
                          term hereof or if the Employee serves notice to not
                          renew this Agreement as provided in paragraph 2;

                  (vi)    The Employee's willful malfeasance in discharging his
                          obligations hereunder and such acts and their
                          consequences are not remedied within ten (10) days or
                          such longer reasonable period of time designated by 
                          the Employer after written notice thereof has been 
                          given to the Employee; or

                  (vii)   The Employee's breach of the provisions of this
                          Agreement and such breach and its consequences are not

<PAGE>   7

                          longer reasonable period of time designated by the 
                          Employer, after written notice thereof has been given 
                          to the Employee.

         (b)      "Without cause" shall mean:

                  (i)     The termination and dissolution of the Employer or a 
                          bona fide decision by the Employer to terminate its 
                          Business; or

                  (ii)    Any involuntary termination of the Employee's
                          employment by the Employer without just cause.

         (c) In addition to those reasons enumerated above, this Agreement shall
be terminated upon the happening of any of the following events:

                  (i)     Whenever the Employer and the Employee shall mutually
                          agree to a termination in writing; or

                  (ii) Upon death of the Employee.

Upon the termination of this Agreement prior to the occurrence of a Change in
Control Date for any of the foregoing reasons in paragraph 10, the Employee
shall be entitled to receive only the compensation accrued but unpaid as of the
date of the termination hereof and shall not be entitled to additional
compensation except as expressly provided in paragraph 9 of this Agreement.

         11. Effect of a Change in Control.

         (a) Involuntary Termination; Consulting Period.

         (i) Consulting Services Following an Involuntary Termination. In the
event of the Employee's Involuntary Termination during the Covered Period he
shall commence providing consulting services to the Employer for a period (the
"Consulting Period") of (i) three years, in the event the Involuntary
Termination occurs during the first year of the Covered Period, (ii) two years,
in the event the Involuntary Termination occurs during the second year of the
Covered Period, or (iii) one year, in the event the Involuntary Termination
occurs in the last year of the Covered Period. The Employee's consulting
services shall consist in advising the Employer on such matters as may be
reasonably requested by the Employer. Such services shall be performed at such
times and in such locations as shall be mutually agreed by the Employee and the
Employer, and shall not interfere with his duties to a new employer. In any
event, the Employee shall not be required to perform consulting services for
more than 8 hours per month during the Consulting Period. The Employee shall not
be an employee of the Employer during the Consulting Period, but shall act
solely in the capacity of an independent contractor.

         (ii) Consulting Fees; Reimbursement of Expenses. In consideration of
the Employee's agreement to provide consulting services hereunder, the Employer
shall pay the Employee, not less than 5 days following an Involuntary
Termination, a lump sum consulting fee 

<PAGE>   8

payment equal to the product of (A) the Employee's base salary in effect
immediately prior to his Date of Termination (without taking into account any
salary reduction that gave rise to Good Reason), and (B) the number of years in
the Consulting Period, as determined pursuant to paragraph 11(a)(i) above. In
addition, the Employee shall be reimbursed for all expenses reasonably incurred
by him in connection with the performance of his consulting services hereunder.
The Employee shall not be entitled to benefits under any other severance pay
plan or arrangement sponsored by the Employer and its subsidiaries in the event
of an Involuntary Termination during the Covered Period, and any amounts payable
to him under any statutory severance policy shall reduce the aggregate amount of
the consulting fees payable hereunder. In addition, in the event of the
Employee's Involuntary Termination, the Employer shall pay him within 5 days of
the date of such Involuntary Termination the full amount of any earned but
unpaid base salary through the Date of Termination at the rate in effect at the
time of the Notice of Termination, plus a cash payment for all unused vacation
time which he may have accrued as of the Date of Termination. The Employer shall
also pay the Employee within 5 days of the Date of Termination a pro rata
portion of his projected annual bonus for the year in which his Involuntary
Termination occurs, calculated on the basis of his target bonus for that year.

         (iii) Benefits. The Employee and his eligible dependents shall continue
to be eligible to participate during the Consulting Period in the medical,
dental, health, life and other fringe benefit plans and arrangements applicable
to him immediately prior to his Involuntary Termination on the same terms and
conditions in effect for the Employee and his dependents immediately prior to
such Involuntary Termination; provided, however, that any benefit plan or
arrangement will end on the date that the Employee and his dependents are
eligible and elect coverage under a plan or arrangement of a subsequent employer
which provides a substantially equivalent or greater benefit to him and his
dependents.

         (iv) Date and Notice of Termination. Any termination of the Employee's
employment during the Covered Period by the Employer or by the Employee shall be
communicated by a notice of termination to the other party hereto (the "Notice
of Termination"). The Notice of Termination shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances, claimed to provide a basis for
termination of the Employee's employment under the provision so indicated. The
date of the Employee's termination of employment with the Employer and its
subsidiaries (the "Date of Termination") shall be determined as follows: (i) if
the Employee's employment is terminated by the Employer in an Involuntary
Termination, five (5) days after the date the Notice of Termination is received
by the Employee and (ii) if the Employee's employment is terminated by the
Employer for just cause, the date specified in the Notice of Termination. If the
basis for the Employee's Involuntary Termination is his resignation for Good
Reason, the Date of Termination shall be ten (10) days after the date his Notice
of Termination is received by the Employer. The Date of Termination for a
resignation of employment other than for Good Reason shall be the date set forth
in the applicable notice, which shall be no earlier than ten (10) days after the
date such notice is received by the Employer.

         (b) Non-Competition Agreement. During the Consulting Period, the
Employee shall comply with the substantive restrictions set forth in paragraphs
8 and 9 above.

<PAGE>   9

         (c) Legal Fees and Expenses. The Employer shall pay or reimburse the
Employee on an after-tax basis for all costs and expenses (including, without
limitation, court costs and reasonable legal fees and expenses which reflect
common practice with respect to the matters involved) incurred by him as a
result of any claim, action or proceeding (i) arising out of his termination of
employment during the Covered Period, (ii) contesting, disputing or enforcing
any right, benefits or obligations under this paragraph 11 or (iii) arising out
of or challenging the validity, advisability or enforceability of this paragraph
I 1 or any provision thereof; provided, however, that this provision will not
apply if the trier of fact determines that the Employee's claim was entirely
without merit.

         (d) Definitions. For purposes of this paragraph 11, the following
capitalized words shall have the meanings set forth below:

         "Cause" shall mean a termination of the Employee's employment by the
Employer which is a result of (i) his felony conviction, (ii) his willful
disclosure of material trade secrets or other material confidential information
related to the business of the Employer and its subsidiaries or (iii) his
willful and continued failure substantially to perform his duties with the
Employer (other than any such failure resulting from his incapacity due to
physical or mental illness or any such actual or anticipated failure resulting
from a resignation by the Employee for Good Reason) after a written demand for
substantial performance is delivered to the Employee by the Board, which demand
specifically identifies the manner in which the Board believes that the Employee
has not substantially performed his duties, and which performance is not
substantially corrected by him within 10 days of receipt of such demand. For
purposes of the previous sentence, no act or failure to act on the Employee's
part shall be deemed "willful" unless done, or omitted to be done, by him not in
good faith and without reasonable belief that his action or omission was in the
best interest of the Employer. Notwithstanding the foregoing, the Employee shall
not be deemed to have been terminated for Cause unless and until there shall
have been delivered to him a copy of a resolution duly adopted by the
affirmative vote of not less than three-fourths (3/4ths) of the entire
membership of the Board at a meeting of the Board called and held for such
purpose (after reasonable notice to the Employee and an opportunity for him,
together with his counsel, to be heard before the Board), finding that in the
good faith opinion of the Board he was guilty of conduct set forth above in
clause (i), (ii) or (iii) of the first sentence of this definition and
specifying the particulars thereof in detail.

         "Change in Control" shall mean the happening of any of the following:

                  (i) any person or entity, including a "group" as defined in
         Section 13(d)(3) of the Exchange Act. other than the Employer, a
         subsidiary of the Employer, or any employee benefit plan of the
         Employer or its subsidiaries, becomes the beneficial owner of the
         Employer's securities having 25 percent or more of the combined voting
         power of the then outstanding securities of the Employer that may be
         cast for the election for directors of the Employer (other than as a
         result of an issuance of securities initiated by the Employer in the
         ordinary course of business); or

<PAGE>   10


                  (ii) as the result of, or in connection with, any cash tender
         or exchange offer, merger or other business combination, sale of assets
         or contested election, or any combination of the foregoing
         transactions, less than a majority of the combined voting power of the
         then outstanding securities of the Employer or any successor
         corporation or entity entitled to vote generally in the election of
         directors of the Employer or such other corporation or entity after
         such transaction, are held in the aggregate by holders of the
         Employer's securities entitled to vote generally in the election of
         directors of the Employer immediately prior to such transactions; or

                  (iii) during any period of two consecutive years, individuals
         who at the beginning of any such period constitute the Board cease for
         any reason to constitute at least a majority thereof, unless the
         election, or the nomination for election by the Employer's
         stockholders, of each director of the Employer first elected during
         such period was approved by a vote of at least two-thirds of the
         directors of the Employer then still in office who were directors of
         the Employer at the beginning of any such period (together, directors
         at the beginning of such period and new directors whose election or
         nomination was so approved are the "Incumbent Directors").

         "Change in Control Date" shall mean the date on which the Change in
Control occurs. Notwithstanding the first sentence of this section, if the
Employee's employment with the Employer terminates prior to the Change in
Control Date and it is reasonably demonstrated that his termination of
employment (i) was at the request of the third party who has taken steps
reasonably calculated to effect the Change in Control or (ii) otherwise arose in
connection with or in anticipation of the Change in Control, then Change in
Control Date shall mean the date immediately prior to the date of the Employee's
termination of employment.

         "Common Stock" shall mean the common stock of the Employer.

         "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended, and any successor provisions thereto.

         "Good Reason" shall mean a resignation by the Employee from his
employment with the Employer on or following the Change in Control Date as a
result of the occurrence of any of the following without his consent:

                  (i) A failure by the Employer to ensure that the Employee's
         position, titles, nature and status of responsibilities and reporting
         obligations are substantially equivalent to those that the Employee
         enjoyed immediately prior to the Change in Control Date, it being
         understood and agreed that such features shall be deemed less than
         substantially equivalent by reason of the Employer ceasing to be a
         public company.

                  (ii) A reduction by the Employer in the Employee's annual base
         salary as in effect immediately prior to the Change in Control Date or
         as the same may be increased from time to time thereafter; a failure by
         the Employer to increase the Employee's salary at a rate commensurate
         with that of other key executives of the Employer; or a reduction

<PAGE>   11

         in the Employee's target annual bonus (expressed as a percentage of
         base salary) below the target in effect for him prior to the Change in
         Control Date;

                  (iii) The relocation of the office of the Employer where the
         Employee is employed immediately prior to the Change in Control Date
         (the "CIC Location") to a location which is more than fifty (50) miles
         away from the CIC Location or the Employer's requiring the Employee to
         be based more than fifty (50) miles away from the CIC Location (except
         for required travel on the Employer's business to an extent
         substantially consistent with his customary business travel obligations
         in the ordinary course of business prior to the Change in Control
         Date), unless such relocation is to a location closer to his principal
         residence;

                  (iv) The failure by the Employer to continue in effect any
         compensation plan in which the Employee participated prior to the
         Change in Control Date or made available to him after the Change in
         Control Date, unless an equitable arrangement (embodied in an ongoing
         substitute or alternative plan) has been made with respect to such plan
         in connection with the Change in Control, or the failure by the
         Employer to continue the Employee's participation therein on at least
         as favorable a basis, both in terms of the amount of benefits provided
         and the level of his participation relative to other participants, as
         existed on the Change in Control Date;

                  (v) The failure by the Employer to continue to provide the
         Employee with benefits at least as favorable in the aggregate to those
         enjoyed by him under the Employer's pension, savings, life insurance,
         medical, health and accident, disability, and fringe benefit plans and
         programs in which he was participating immediately prior to the Change
         in Control Date, or the failure by the Employer to provide the Employee
         with the number of paid vacation days to which he is entitled on the
         basis of years of service with the Employer in accordance with the
         Employer's normal vacation policy in effect immediately prior to the
         Change in Control;

                  (vi) The failure of the Employer to obtain an agreement
         reasonably satisfactory to the Employee from any successor to assume
         and agree to perform this Agreement, as contemplated in paragraph 12(a)
         hereof or, if the business of the Employer for which the Employee's
         services are principally performed is sold at any time after a Change
         in Control, the failure of the Employer to obtain such an agreement
         from the purchaser of such business;

                  (vii) Any termination of the Employee's employment which is
         not effected pursuant to the terms of this Agreement; or

                  (viii) A material breach by the Employer of the provisions of
this Agreement;

provided, however, that an event described above in clause (i), (ii), (iv), (v)
or (viii) shall not constitute Good Reason unless it is communicated by the
Employee to the Employer in writing and is not corrected by the Employer in a
manner which is reasonably satisfactory to the

<PAGE>   12

Employee (including full retroactive correction with respect to any monetary
matter) within 10 days of the Employer's receipt of such written notice from
him.

         "Involuntary Termination" shall mean (i) the termination of the
Employee's employment during the Covered Period by the Employer and its
subsidiaries other than for Cause or disability or (ii) the Employee's
resignation of employment during the Covered Period with the Employer and its
subsidiaries for Good Reason.

         12. Successors, Binding Agreement.

         (a) Assumption by Successor. The Employer will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Employer expressly to
assume and to agree to perform this Agreement in the same manner and to the same
extent that the Employer would be required to perform it if no such succession
had taken place; provided, however, that no such assumption shall relieve the
Employer of its obligations hereunder. As used in this Agreement, the "Employer"
shall mean the Employer as hereinbefore defined and any successor to its
business and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law or otherwise.

         (b) Enforceability; Beneficiaries. This Agreement shall be binding upon
and inure to the benefit of the Employee (and his personal representatives and
heirs) and the Employer and any organization which succeeds to substantially all
of the business or assets of the Employer, whether by means of merger,
consolidation, acquisition of all or substantially all of the assets of the
Employer or otherwise, including, without limitation, as a result of a Change in
Control or by operation of law. This Agreement shall inure to the benefit of and
be enforceable by the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Employee should die while any amount would still be payable to him hereunder if
he had continued to live, all such amounts. unless otherwise provided herein,
shall be paid in accordance with the terms of this Agreement to his devisee,
legatee or other designee or, if there is no such designee, to his estate.

         13. Notices. Any notice required or permitted to be given under this
Agreement shall be sufficient if in writing and delivered personally or sent by
registered mail (i) to Employee's residence, in the case of the Employee, or
(ii) to the business address of its President and Chief Executive Officer, in
the case of the Employer.

         14. Waiver of Breach and Severability. The waiver by the Employer of a
breach of any provision of this Agreement by the Employee shall not operate or
be construed as a waiver of any subsequent breach by the Employee. In the event
any provision of this Agreement is found to be invalid or unenforceable, it may
be severed from the Agreement and the remaining provision of the Agreement shall
continue to be binding and effective; provided, however, that, if possible, it
is the intention of the Employer and the Employee that such provision be
construed and interpreted as narrowly as necessary in order to make such
provision valid and enforceable.

<PAGE>   13

         15. Entire Agreement. This instrument and the letter agreement between
the Employee and the Employer dated January 1, 1996 contain the entire agreement
of the parties and supersede any prior understandings and agreements between
them respecting the subject matter of this Agreement, including, without
limitation, the Employment Agreement dated as of January 1, 1996. It may not be
changed orally, but only by an agreement in writing signed by the party against
whom enforcement of any waiver, change, modification, extension or discharge is
sought.

         16. Survival. Upon termination of the Employee's employment with the
Company prior to a Change in Control Date, the rights and obligations of the
parties hereto as provided in paragraphs 8 and 9 shall continue for the time
periods as set forth herein.

         17. Governing Law. This Agreement shall be construed in accordance with
and governed by the laws of the State of Tennessee without regard to the laws of
any other state or jurisdiction. Any action brought or maintained in connection
with this Agreement shall be brought exclusively in the courts located in Shelby
County, Tennessee. Each of the Employer and the Employee hereby irrevocably
waives all right to trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement.

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         AMENDED AND RESTATED EMPLOYMENT AGREEMENT, dated as of the 13th day of
April, 1997, between SOFAMOR DANEK GROUP, INC., an Indiana corporation (the
"Employer"), and Mark LoGuidice (the "Employee"),

                                    RECITALS

         WHEREAS, the Employer is an Indiana corporation and through its wholly
owned subsidiaries, Warsaw Orthopedic, Inc., Danek Medical, Inc., and Sofamor,
S.N.C. is engaged in the business of developing, manufacturing and distributing
medical devices, trauma instruments, surgical tools and implants (such business,
as it may change from time to time, is hereinafter referred to as "Business");
and

         WHEREAS, the Board of Directors of the Employer (the "Board") has
concluded that it desires to retain the valued services of the Employee by
entering into a new agreement which shall provide the Employee with certain
additional protections which are designed to ensure that the Employee will
devote himself attentively and energetically to his duties without distraction;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants contained herein, the parties agree as follows:

         1. Employment. The Employer (or a subsidiary of the Employer) hereby 
employs the Employee and the Employee hereby accepts employment upon the terms
and conditions hereinafter set forth.

         2. Term. Subject to the provisions for termination as provided in
paragraph 10 hereof, the term of this Agreement shall be from April 13, 1997 to
December 31, 1999, and it shall be automatically renewed for successive one (1)
year periods thereafter, unless either party elects not to renew this Agreement
by serving notice of such intention not to renew on the other party at least
ninety (90) days prior to the renewal date. Notwithstanding the foregoing, if a
Change in Control Date (as defined in paragraph 11) occurs during the term
described in the immediately preceding sentence, the term of the Employee's
employment hereunder shall extend until the third anniversary of such Change in
Control Date (the period beginning on such Change in Control Date and ending on
the third anniversary thereof being hereinafter referred to as the "Covered
Period").

         3. Duties. The Employee is engaged as President, Sofamor Danek U.S.A.

instructed in writing by the Employer, the Employee will not, at any time,
disclose to others, or use, or allow anyone else to disclose or use any

Employee's employment with the Employer), unless, until and then only to the
extent that such Confidential Information has become ascertainable or obtained
from public or published sources or was available to the Employee on a
non-confidential basis prior to any such disclosure or use, provided that the
source of such material is or was not bound by an obligation of confidentiality
to the Employer. This paragraph 8 shall survive termination of this Agreement.

applicable during the Employee's employment and upon the termination of such

         The Employee acknowledges that because of his skills, the Employee's
position with the Employer and the Confidential Information to which the
Employee shall have access or be provided on account of such employment with the
Employer, competition by the Employee with the Employer could damage the
Employer in a manner which cannot adequately be compensated by damages or an
action at law. In view of such circumstances, because of the Confidential
Information obtained by, or disclosed to the Employee, and as a material
inducement to the Employer to enter into this Agreement and to compensate the
Employee, as described in paragraph 5, as well as provide him with additional
benefits as provided herein and other good and valuable consideration, the
Employee covenants and agrees that:

         (a) Noncompetition. During the Employee's employment with the Employer
and for a period of three (3) years thereafter, the Employee shall not (as
principal, agent, employee, consultant or otherwise), directly or indirectly, in
any geographic area in which the Employer is engaged in Business, engage in
activities for, or render services of any nature to, any firm or business, which
firm or business competes, directly or indirectly, with the Employer or the
Business.

         (b) Nonsolicitation of Customers. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit, divert or accept any work or services
which compete with the Employer's Business from any customer of the Employer or
seek to cause any such customer to refrain from doing business with or
patronizing the Employer.

not, directly or indirectly, solicit for employment or employ any current or
former employee of the Employer.

indirectly" shall be construed in its broadest sense and shall include the

any activity engaged in or conducted by the Employer or any of its subsidiaries,

affiliates or joint ventures intends to engage in or conduct. The term if
customer" shall mean any person or entity with which the Employer, or any of its
subsidiaries, affiliates or joint ventures has engaged in or conducted Business
during the one (1) year period prior to the date the Employee ceased employment
with the Employer or any persons or entities targeted by the Employer or
contacted for the purpose of engaging in or conducting Business during such one
(1) year period.

         (e) Reasonable Limitations. Given the important nature of the position
the Employee will hold with the Employer, the nature of the Employer's Business
and the sensitive nature of the Confidential Information and duties the Employee
will have with the Employer, the parties acknowledge that the limitations,
including but not limited to, the scope of activities prohibited, the geographic
area covered and the time limitation, are reasonable.

         In the event of an actual or threatened breach by the Employee of the
provisions of paragraphs 8 and 9 of this Agreement, the Employer shall be
entitled to a temporary restraining order and an injunction restraining the
Employee from such breach. Nothing herein, however, shall be construed as
prohibiting the Employer from pursuing any other remedies available to it for
such actual or threatened breach, including, without limitation, the recovery of
damages and reasonable attorneys' and paralegals' fees and costs from the
Employee. If the Employee violates any of the covenants in paragraphs 8 and 9 of
this Agreement, the term and the covenant violated shall be automatically
extended for the period of time of the violation, either from the date on which

competent jurisdiction of an order or judgment enforcing such covenants,
whichever period is later.

         10. Termination Prior to a Change in Control Date. The Employer may, at
its option, terminate this Agreement at any time prior to the occurrence of a

         11. Effect of a Change in Control.

         (a) Involuntary Termination; Consulting Period.

         (i) Consulting Services Following an Involuntary Termination. In the
event of the Employee's Involuntary Termination during the Covered Period he
shall commence providing consulting services to the Employer for a period (the
"Consulting Period") of (i) three years, in the event the Involuntary
Termination occurs during the first year of the Covered Period, (ii) two years,
in the event the Involuntary Termination occurs during the second year of the
Covered Period, or (iii) one year, in the event the Involuntary Termination
occurs in the last year of the Covered Period. The Employee's consulting
services shall consist in advising the Employer on such matters as may be
reasonably requested by the Employer. Such services shall be performed at such
times and in such locations as shall be mutually agreed by the Employee and the
Employer, and shall not interfere with his duties to a new employer. In any
event, the Employee shall not be required to perform consulting services for
more than 8 hours per month during the Consulting Period. The Employee shall not
be an employee of the Employer during the Consulting Period, but shall act
solely in the capacity of an independent contractor.

         (ii) Consulting Fees; Reimbursement of Expenses. In consideration of
the Employee's agreement to provide consulting services hereunder, the Employer
shall pay the Employee, not less than 5 days following an Involuntary
Termination, a lump sum consulting fee



<PAGE>   8

payment equal to the product of (A) the Employee's base salary in effect
immediately prior to his Date of Termination (without taking into account any
salary reduction that gave rise to Good Reason), and (B) the number of years in
the Consulting Period, as determined pursuant to paragraph 11 (a)(1) above. in
addition, the Employee shall be reimbursed for all expenses reasonably incurred
by him in connection with the performance of his consulting services hereunder.
The Employee shall not be entitled to benefits under any other severance pay
plan or arrangement sponsored by the Employer and its subsidiaries in the event
of an Involuntary Termination during the Covered Period, and any amounts payable
to him under any statutory severance policy shall reduce the aggregate amount of
the consulting fees payable hereunder. In addition, in the event of the
Employee's Involuntary Termination, the Employer shall pay him within 5 days of
the date of such Involuntary Termination the full amount of any earned but
unpaid base salary through the Date of Termination at the rate in effect at the
time of the Notice of Termination, plus a cash payment for all unused vacation
time which he may have accrued as of the Date of Termination. The Employer shall
also pay the Employee within 5 days of the Date of Termination a pro rata
portion of his projected annual bonus for the year in which his Involuntary
Termination occurs, calculated on the basis of his target bonus for that year.

         (iii) Benefits. The Employee and his eligible dependents shall continue
to be eligible to participate during the Consulting Period in the medical,
dental, health, life and other fringe benefit plans and arrangements applicable
to him immediately prior to his Involuntary Termination on the same terms and
conditions in effect for the Employee and his dependents immediately prior to
such Involuntary Termination; provided, however, that any benefit plan or
arrangement will end on the date that the Employee and his dependents are
eligible and elect coverage under a plan or arrangement of a subsequent employer
which provides a substantially equivalent or greater benefit to him and his
dependents.

         (iv) Date and Notice of Termination. Any termination of the Employee's
employment during the Covered Period by the Employer or by the Employee shall be
communicated by a notice of termination to the other party hereto (the "Notice
of Termination"), The Notice of Termination shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Employee's employment under the provision so indicated. The
date of the Employee's termination of employment with the Employer and its
subsidiaries (the "Date of Termination") shall be determined as follows: (i) if
the Employee's employment is terminated by the Employer in an Involuntary
Termination, five (5) days after the date the Notice of Termination is received
by the Employee and (ii) if the Employee's employment is terminated by the
Employer for just cause, the date specified in the Notice of Termination. If the
basis for the Employee's Involuntary Termination is his resignation for Good
Reason, the Date of Termination shall be ten (10) days after the date his Notice
of Termination is received by the Employer. The Date of Termination for a
resignation of employment other than for Good Reason shall be the date set forth
in the applicable notice, which shall be no earlier than ten (10) days after the
date such notice is received by the Employer.

         (b) Non-Competition Agreement. During the Consulting Period, the
Employee shall comply with the substantive restrictions set forth in paragraphs
8 and 9 above.

<PAGE>   9

         (c) Legal Fees and Expenses. The Employer shall pay or reimburse the
Employee on an after-tax basis for all costs and expenses (including, without
limitation, court costs and reasonable legal fees and expenses which reflect
common practice with respect to the matters involved) incurred by him as a
result of any claim, action or proceeding (i) arising out of his termination of
employment during the Covered Period, (ii) contesting, disputing or enforcing
any right, benefits or obligations under this paragraph II or (iii) arising out
of or challenging the validity, advisability or enforceability of this paragraph
11 or any provision thereof; provided, however, that this provision will not
apply if the trier of fact determines that the Employee's claim was entirely
without merit.

         (d) Definitions. For purposes of this paragraph 11, the following
capitalized words shall have the meanings set forth below:

         "Cause" shall mean a termination of the Employee's employment by the
Employer which is a result of (1) his felony conviction, (ii) his willful
disclosure of material trade secrets or other material confidential information
related to the business of the Employer and its subsidiaries or (iii) his
willful and continued failure substantially to perform his duties with the
Employer (other than any such failure resulting from his incapacity due to
physical or mental illness or any such actual or anticipated failure resulting
from a resignation by the Employee for Good Reason) after a written demand for
substantial performance is delivered to the Employee by the Board, which demand
specifically identifies the manner in which the Board believes that the Employee
has not substantially performed his duties, and which performance is not
substantially corrected by him within 10 days of receipt of such demand. For
purposes of the previous sentence, no act or failure to act on the Employee's
part shall be deemed "willful" unless done, or omitted to be done, by him not in
good faith and without reasonable belief that his action or omission was in the
best interest of the Employer. Notwithstanding the foregoing, the Employee shall
not be deemed to have been terminated for Cause unless and until there shall
have been delivered to him a copy of a resolution duly adopted by the
affirmative vote of not less than three-fourths (3/4ths) of the entire
membership of the Board at a meeting of the Board called and held for such
purpose (after reasonable notice to the Employee and an opportunity for him,
together with his counsel, to be heard before the Board), finding that in the
good faith opinion of the Board he was guilty of conduct set forth above in
clause (i), (ii) or (iii) of the first sentence of this definition and
specifying the particulars thereof in detail.

         "Change in Control" shall mean the happening of any of the following:

                  (i) any person or entity, including a "group" as defined in
         Section 13(d)(3) of the Exchange Act, other than the Employer, a
         subsidiary of the Employer, or any employee benefit plan of the
         Employer or its subsidiaries, becomes the beneficial owner of the
         Employer's securities having 25 percent or more of the combined voting
         power of the then outstanding securities of the Employer that may be
         cast for the election for directors of the Employer (other than as a
         result of an issuance of securities initiated by the Employer in the
         ordinary course of business); or

<PAGE>   10

                  (ii) as the result of, or in connection with, any cash tender
         or exchange offer, merger or other business combination, sale of assets
         or contested election, or any combination of the foregoing
         transactions, less than a majority of the combined voting power of the
         then outstanding securities of the Employer or any successor
         corporation or entity entitled to vote generally in the election of
         directors of the Employer or such other corporation or entity after
         such transaction, are held in the aggregate by holders of the
         Employer's securities entitled to vote generally in the election of
         directors of the Employer immediately prior to such transactions; or

                  (iii) during any period of two consecutive years, individuals
         who at the beginning of any such period constitute the Board cease for
         any reason to constitute at least a majority thereof, unless the
         election, or the nomination for election by the Employer's
         stockholders, of each director of the Employer first elected during
         such period was approved by a vote of at least two-thirds of the
         directors of the Employer then still in office who were directors of
         the Employer at the beginning of any such period (together, directors
         at the beginning of such period and new directors whose election or
         nomination was so approved are the "Incumbent Directors").

         "Change in Control Date" shall mean the date on which the Change in
Control occurs, Notwithstanding the first sentence of this section, if the
Employee's employment with the Employer terminates prior to the Change in
Control Date and it is reasonably demonstrated that his termination of
employment (i) was at the request of the third party who has taken steps
reasonably calculated to effect the Change in Control or (ii) otherwise arose in
connection with or in anticipation of the Change in Control, then Change in
Control Date shall mean the date immediately prior to the date of the Employee's
termination of employment.

         "Common Stock" shall mean the common stock of the Employer.

         "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended, and any successor provisions thereto.

         "Good Reason" shall mean a resignation by the Employee from his
employment with the Employer on or following the Change in Control Date as a
result of the occurrence of any of the following without his consent:

                  (i) A failure by the Employer to ensure that the Employee's
         position, titles, nature and status of responsibilities and reporting
         obligations are substantially equivalent to those that the Employee
         enjoyed immediately prior to the Change in Control Date, it being
         understood and agreed that such features shall not be deemed less than
         substantially equivalent solely by reason of the Employer ceasing to be
         a public company.

                  (ii) A reduction by the Employer in the Employee's annual base
         salary as in effect immediately prior to the Change in Control Date or
         as the same may be increased from time to time thereafter; a failure by
         the Employer to increase the Employee's salary at a rate commensurate
         with that of other key executives of the Employer; or a reduction 

<PAGE>   11

         in the Employee's target annual bonus (expressed as a percentage of
         base salary) below the target in effect for him prior to the Change in
         Control Date;

                  (iii) The relocation of the office of the Employer where the
         Employee is employed immediately prior to the Change in Control Date
         (the "CIC Location") to a location which is more than fifty (50) miles
         away from the CIC Location or the Employer's requiring the Employee to
         be based more than fifty (50) miles away from the CIC Location (except
         for required travel on the Employer's business to an extent
         substantially consistent with his customary business travel obligations
         in the ordinary course of business prior to the Change in Control
         Date), unless such relocation is to a location closer to his principal
         residence;

                  (iv) The failure by the Employer to continue in effect any
         compensation plan in which the Employee participated prior to the
         Change in Control Date or made available to him after the Change in
         Control Date, unless an equitable arrangement (embodied in an ongoing
         substitute or alternative plan) has been made with respect to such plan
         in connection with the Change in Control, or the failure by the
         Employer to continue the Employee's participation therein on at least
         as favorable a basis, both in terms of the amount of benefits provided
         and the level of his participation relative to other participants, as
         existed on the Change in Control Date;

                  (v) The failure by the Employer to continue to provide the
         Employee with benefits at least as favorable in the aggregate to those
         enjoyed by him under the Employer's pension, savings, life insurance,
         medical, health and accident, disability, and fringe benefit plans and
         programs in which he was participating immediately prior to the Change
         in Control Date; or the failure by the Employer to provide the Employee
         with the number of paid vacation days to which he is entitled on the
         basis of years of service with the Employer in accordance with the
         Employer's normal vacation policy in effect immediately prior to the
         Change in Control;

                  (vi) The failure of the Employer to obtain an agreement
         reasonably satisfactory to the Employee from any successor to assume
         and agree to perform this Agreement, as contemplated in paragraph 12(a)
         hereof or, if the business of the Employer for which the Employee's
         services are principally performed is sold at any time after a Change
         in Control, the failure of the Employer to obtain such an agreement
         from the purchaser of such business;

                  (vii) Any termination of the Employee's employment which is
         not effected pursuant to the terms of this Agreement; or

                  (viii) A material breach by the Employer of the provisions of
this Agreement;

provided, however, that an event described above in clause (i), (ii), (iv), (v)
or (viii) shall not constitute Good Reason unless it is communicated by the
Employee to the Employer in writing and is not corrected by the Employer in a
manner which is reasonably satisfactory to the


<PAGE>   12

Employee (including full retroactive correction with respect to any monetary
matter) within 10 days of the Employer's receipt of such written notice from
him.

         "Involuntary Termination" shall mean (i) the termination of the
Employee's employment during the Covered Period by the Employer and its
subsidiaries other than for Cause or disability or (ii) the Employee's
resignation of employment during the Covered Period with the Employer and its
subsidiaries for Good Reason.

         12. Successors; Binding Agreement.

         (a) Assumption by Successor. The Employer will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Employer expressly to
assume and to agree to perform this Agreement in the same manner and to the same
extent that the Employer would be required to perform it if no such succession
had taken place- provided, however, that no such assumption shall relieve the
Employer of its obligations hereunder. As used in this Agreement, the "Employer"
shall mean the Employer as hereinbefore defined and any successor to its
business and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law or otherwise.

         (b) Enforceability, Beneficiary. This Agreement shall be binding upon
and inure to the benefit of the Employee (and his personal representatives and
heirs) and the Employer and any organization which succeeds to substantially all
of the business or assets of the Employer, whether by means of merger,
consolidation, acquisition of all or substantially all of the assets of the
Employer or otherwise, including, without limitation, as a result of a Change in
Control or by operation of law. This Agreement shall inure to the benefit of and
be enforceable by the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Employee should die while any amount would still be payable to him hereunder if
he had continued to live, all such amounts, unless otherwise provided herein,
shall be paid in accordance with the terms of this Agreement to his devisee,
legatee or other designee or, if there is no such designee, to his estate.

         13. Notices. Any notice required or permitted to be given under this
Agreement shall be sufficient if in writing and delivered personally or sent by
registered mail (i) to Employee's residence, in the case of the Employee, or
(ii) to the business address of its President and Chief Executive Officer, in
the case of the Employer.

         14. Waiver of Breach and Severability. The waiver by the Employer of a
breach of any provision of this Agreement by the Employee shall not operate or
be construed as a waiver of any subsequent breach by the Employee. In the event
any provision of this Agreement is found to be invalid or unenforceable, it may
be severed from the Agreement and the remaining provision of the Agreement shall
continue to be binding and effective; provided, however, that, if possible, it
is the intention of the Employer and the Employee that such provision be
construed and interpreted as narrowly as necessary in order to make such
provision valid and enforceable.

         15. Entire Agreement. This instrument and the letter agreement between
the Employee and the Employer dated January 1, 1996 contain the entire agreement
of the parties and supersede any prior understandings and agreements between
them respecting the subject matter of this Agreement, including, without
limitation, the Employment Agreement dated as of January 1, 1996. It may not be
changed orally, but only by an agreement in writing signed by the party against
whom enforcement of any waiver, change, modification, extension or discharge is
sought.

         16. Survival. Upon termination of the Employee's employment with the
Company prior to a Change in Control Date, the rights and obligations of the
parties hereto as provided in paragraphs 8 and 9 shall continue for the time
periods as set forth herein.

         17. Governing Law. This Agreement shall be construed in accordance with
and governed by the laws of the State of Tennessee without regard to the laws of
any other state or jurisdiction. Any action brought or maintained in connection
with this Agreement shall be brought exclusively in the courts located in Shelby
County, Tennessee. Each of the Employer and the Employee hereby irrevocably
waives all right to trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement.

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         AMENDED AND RESTATED EMPLOYMENT AGREEMENT, dated as of the 13th day of
April, 1997, between SOFAMOR DANEK GROUP, INC., an Indiana corporation (the
"Employer"), and Mark Merrill (the "Employee").

                                    RECITALS

         WHEREAS, the Employer is an Indiana corporation and through its wholly
owned subsidiaries, Warsaw Orthopedic, Inc., Danek Medical, Inc., and Sofamor,
S.N.C. is engaged in the business of developing, manufacturing and distributing
medical devices, trauma instruments, surgical tools and implants (such business,
as it may change from time to time, is hereinafter referred to as "Business");
and

         WHEREAS, the Board of Directors of the Employer (the "Board") has
concluded that it desires to retain the valued services of the Employee by
entering into a new agreement which shall provide the Employee with certain
additional protections which are designed to ensure that the Employee will
devote himself attentively and energetically to his duties without distraction;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants contained herein, the parties agree as follows:

         1. Employment. The Employer (or a subsidiary of the Employer) hereby
employs the Employee and the Employee hereby accepts employment upon the terms
and conditions hereinafter set forth.

         2. Term. Subject to the provisions for termination as provided in
paragraph 10 hereof, the term of this Agreement shall be from April 13, 1997 to
December 31, 1999, and it shall be automatically renewed for successive one (1)
year periods thereafter, unless either party elects not to renew this Agreement
by serving notice of such intention not to renew on the other party at least
ninety (90) days prior to the renewal date. Notwithstanding the foregoing, if a
Change in Control Date (as defined in paragraph 11) occurs during the term
described in the immediately preceding sentence, the term of the Employee's
employment hereunder shall extend until the third anniversary of such Change in
Control Date (the period beginning on such Change in Control Date and ending on
the third anniversary thereof being hereinafter referred to as the "Covered
Period").

         3. Duties. The Employee is engaged as Vice President and Treasurer of
the Employer to assist the President and CEO of the Employer in managing,
directing and administering all aspects and matters of the Business, subject to
the direction and guidance of the President and CEO of the Employer. Prior to a
Change in Control (as hereinafter defined), the precise services, duties and
authority of the Employee as Vice President and Treasurer of the

<PAGE>   3

Employer may be further defined, extended or curtailed from time to time at the
discretion of the President and CEO of the Employer.

         4. Extent of Services. The Employee shall have the power and authority
commensurate and necessary to his position of Vice President and Treasurer and
his other duties as assigned to him from time to time. He shall devote his
entire employable time, attention and best efforts to the Business as may be
necessary to efficiently and effectively perform and complete the duties he is
to undertake as described in this Agreement. The Employee shall not, without the
consent of the Employer, which consent shall not be unreasonably withheld,
during the term of this Agreement, be actively engaged in any other business
activity, whether or not such business activity is pursued for gain, profit and
other pecuniary advantage; but this shall not be construed as preventing the
Employee from investing his personal assets in such form or manner as will not
require any services on the part of the Employee in the operation of the affairs
of the companies in which such investments are made.

         5. Compensation. The Employee shall be compensated for services
rendered hereunder as follows:

         (a) The Employee shall receive a salary of not less than $14,167 per
month for each month of the first twelve (12) months that this Agreement is in
effect and for each month thereafter so long as the Employee receives Job
Performance Evaluations of "good" or better. After such first year, if the
Employee receives a Job Performance Evaluation of less than "good", his salary
shall be determined in the discretion of the President and CEO of the Employer.
Such salary paid to the Employee shall be subject to withholding of taxes and
other appropriate and customary amounts.

         (b) The Employee shall be entitled to participate in the employee
benefit plans the Employer may adopt from time to time for its management or
supervisory personnel generally at such time as the Employee shall have
fulfilled the eligibility requirements for participation therein as shall be
determined by the terms of the applicable contracts for each program. Nothing
herein shall be construed so as to prevent the Employer from modifying or
terminating any employee benefit plans or programs or employee fringe benefits
it currently sponsors or may adopt from time to time.

         6. Expenses and Travel. It is expected that in the course of his
employment, the Employee and his spouse shall be required to spend time
traveling and entertaining various persons on behalf of the Employer and
promoting the affairs of the Employer. The Employer shall provide to the
Employee an Employer Mastercard credit card or the Employer shall pay the
Employee the annual fee for one (1) personal credit card. The Employer shall pay
for or reimburse the Employee for all such reasonable expenses upon the
Employee's periodic presentation of an itemized account of such expenditures.
provided, however, the Employer shall only pay for or reimburse for the cost of
coach class air fare for business travel within the United States and only for
the cost of business class air fare for international business air travel. The
Employer shall bear the expense, in an amount not to exceed $250 per month, for
country club or social club dues for which the Employee may become a member
during the term hereof and/or a 


<PAGE>   4

portable telephone and related telephone service, the use of either of which is
related to the Business. The Employee shall bear the expense of any initiation
fees and other assessments for or resulting from such membership. The Employee
shall be reimbursed in an amount not to exceed a total of $2,000 for each year
during the term or any renewal term hereof, for expenses incurred for his spouse
when traveling with the Employee on business matters for the Employer.

         7. Disability. If the Employee shall become physically or mentally
disabled during the ten-n of this Agreement to the extent that he shall be
unable to perform his duties and services for and on behalf of the Employer, the
benefits made available to the Employee and the salary then payable to the
Employee pursuant to the foregoing paragraph 5 shall continue to be made
available and paid to the Employee for the shorter of (i) the period of
disability; or (ii) six (6) months from the commencement of the disability.
Thereafter, the Employee shall receive no salary from the Employer.

         8. Confidentiality. The Employee possesses and will continue to possess
information which has been created, discovered, developed by or otherwise become
known to the Employee (including information discovered or made available by
subsidiaries, affiliates or joint ventures of the Employer or in which property
rights have been assigned or otherwise conveyed to the Employer), which
information has commercial value to the Employer, including but not limited to
trade secrets, innovations, processes, computer codes, data, know-how,
improvements, discoveries, developments, techniques, marketing plans,
strategies, costs, customer and client lists, or any information the Employee
has reason to know the Employer would treat as confidential for any purpose,
whether or not developed by the Employee (hereinafter referred to as
"Confidential Information"). Unless previously authorized in writing or
instructed in writing by the Employer, the Employee will not, at any time,
disclose to others, or use, or allow anyone else to disclose or use any
Confidential Information (except as may be necessary in the performance of the
Employee's employment with the Employer), unless, until and then only to the
extent that such Confidential Information has become ascertainable or obtained
from public or published sources or was available to the Employee on a
non-confidential basis prior to any such disclosure or use, provided that the
source of such material is or was not bound by an obligation of confidentiality
to the Employer. This paragraph 8 shall survive termination of this Agreement.

         9. Restrictive Covenants. The terms of this paragraph 9 shall be
applicable during the Employee's employment and upon the termination of such
employment for any reason occurring prior to a Change in Control Date. In the
event of termination it without cause" as defined in paragraph 10(b) occurring
prior to a Change in Control Date, in consideration of, and subject to, the
Employee's continued compliance with the terms of this paragraph 9, the Employer
shall pay to the Employee twelve (12) months salary based on his salary for the
month immediately preceding the date of termination which shall be paid in
accordance with the Employer's customary payroll practices over twelve (12)
months. In the event of a termination for any other reason, including for "just
cause" as defined in paragraph 10(b) occurring prior to a Change in Control
Date, the Employer shall have no obligation to the Employee. This paragraph 9
shall survive termination of this Agreement occurring prior to a Change in
Control Date.

         The Employee acknowledges that because of his skills, the Employee's
position with the Employer and the Confidential Information to which the
Employee shall have access or be provided on account of such employment with the
Employer, competition by the Employee with the Employer could damage the
Employer in a manner which cannot adequately be compensated by damages or an
action at law. In view of such circumstances, because of the Confidential
Information obtained by, or disclosed to the Employee, and as a material
inducement to the Employer to enter into this Agreement and to compensate the
Employee, as described in paragraph 5, as well as provide him with additional
benefits as provided herein and other good and valuable consideration, the
Employee covenants and agrees that:

         (a) Noncompetition. During the Employee's employment with the Employer
and for a period of three (3) years thereafter, the Employee shall not (as
principal, agent, employee, consultant or otherwise), directly or indirectly, in
any geographic area in which the Employer is engaged in Business, engage in
activities for, or render services of any nature to, any firm or business, which
firm or business competes, directly or indirectly, with the Employer or the
Business.

         (b) Nonsolicitation of Customers. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit, divert or accept any work or services
which compete with the Employer's Business from any customer of the Employer or
seek to cause any such customer to refrain from doing business with or
patronizing the Employer.

         (c) Nonsolicitation of Employees. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit for employment or employ any current or
former employee of the Employer.

         (d) Definitions. For purposes of this Agreement, the term "directly or
indirectly" shall be construed in its broadest sense and shall include the
activities of the members of the Employee's immediate family or any partnership.
The term "Business" shall be construed in its broadest sense and shall include
any activity engaged in or conducted by the Employer or any of its subsidiaries,
affiliates or joint ventures or which the Employer or any of its subsidiaries,
affiliates or joint ventures intends to engage in or conduct. The term
"customer" shall mean any person or entity with which the Employer, or any of
its subsidiaries, affiliates or joint ventures has engaged in or conducted
Business during the one (1) year period prior to the date the Employee ceased
employment with the Employer or any persons or entities targeted by the Employer
or contacted for the purpose of engaging in or conducting Business during such
one (1) year period.

         (e) Reasonable Limitations. Given the important nature of the position
the Employee will hold with the Employer, the nature of the Employer's Business
and the sensitive nature of the Confidential Information and duties the Employee
will have with the Employer, the parties acknowledge that the limitations,
including but not limited to, the scope of activities prohibited, the geographic
area covered and the time limitation, are reasonable.

         In the event of an actual or threatened breach by the Employee of the
provisions of paragraphs 8 and 9 of this Agreement, the Employer shall be
entitled to a temporary restraining order and an injunction restraining the
Employee from such breach. Nothing herein, however, shall be construed as
prohibiting the Employer from pursuing any other remedies available to it for
such actual or threatened breach, including, without limitation, the recovery of
damages and reasonable attorneys' and paralegals' fees and costs from the
Employee. If the Employee violates any of the covenants in paragraphs 8 and 9 of
this Agreement, the term and the covenant violated shall be automatically
extended for the period of time of the violation, either from the date on which
the Employee ceases such violation or from the date of the entry by a court of
competent jurisdiction of an order or judgment enforcing such covenants,
whichever period is later.

         10. Termination Prior to a Change in Control Date. The Employer may, at
its option, terminate this Agreement at any time prior to the occurrence of a
Change in Control Date upon written notice to the Employee for just cause or
without cause.

         (a)      "Just cause" shall include, but not be limited to:

                   (i)    The Employee receiving a Job Performance Evaluation of
                          less than "good";

                   (ii)   The Employee's misuse or embezzlement of funds
                          belonging to the Employer, conviction of a felony or
                          crime involving moral turpitude or use of alcohol or
                          drugs in such a manner as will injure or adversely
                          affect the reputation of the Employer or its
                          employees, customers, agents, officers or directors;

                   (iii)  The Employee's absence from his employment, for
                          whatever cause, other than by disability for which
                          salary is continued pursuant to paragraph 7, for a
                          period of thirty (30) consecutive days or more;

                   (iv)   The Employee's absence from employment as a result of
                          disability beyond the period for which salary is
                          continued pursuant to paragraph 7;

                   (v)    The Employee's resignation from employment during the
                          term hereof or if the Employee serves notice to not
                          renew this Agreement as provided in paragraph 2;

                   (vi)   The Employee's willful malfeasance in discharging his
                          obligations hereunder and such acts and their
                          consequences are not remedied within ten (10) days or
                          such longer reasonable period of time designated by
                          the Employer after written notice thereof has been
                          given to the Employee; or

                   (vii)  The Employee's breach of the provisions of this
                          Agreement and such breach and its consequences are not
                          remedied within ten (10) days or such longer
                          reasonable period of time designated by the Employer,
                          after written notice thereof has been given to the
                          Employee.

<PAGE>   7


         (b)      "Without cause" shall mean:

                   (i)    The termination and dissolution of the Employer or a
                          bona fide decision by the Employer to terminate its
                          Business; or

                   (ii)   Any involuntary termination of the Employee's
                          employment by the Employer without just cause.

         (c) In addition to those reasons enumerated above, this Agreement shall
be terminated upon the happening of any of the following events:

                   (i)    Whenever the Employer and the Employee shall mutually 
                          agree to a termination in writing; or

                   (ii)   Upon death of the Employee.

Upon the termination of this Agreement prior to the occurrence of a Change in
Control Date for any of the foregoing reasons in paragraph 10, the Employee
shall be entitled to receive only the compensation accrued but unpaid as of the
date of the termination hereof and shall not be entitled to additional
compensation except as expressly provided in paragraph 9 of this Agreement.

         11. Effect of a Change in Control.

         (a) Involuntary Termination, Consulting Period.

         (i) Consulting Services Following an Involuntary Termination. In the
event of the Employee's Involuntary Termination during the Covered Period he
shall commence providing consulting services to the Employer for a period (the
"Consulting Period") of (i) three years, in the event the Involuntary
Termination occurs during the first year of the Covered Period, (ii) two years,
in the event the Involuntary Termination occurs during the second year of the
Covered Period, or (iii) one year, in the event the Involuntary Termination
occurs in the last year of the Covered Period. The Employee's consulting
services shall consist in advising the Employer on such matters as may be
reasonably requested by the Employer. Such services shall be performed at such
times and in such locations as shall be mutually agreed by the Employee and the
Employer, and shall not interfere with his duties to a new employer. In any
event, the Employee shall not be required to perform consulting services for
more than 8 hours per month during the Consulting Period. The Employee shall not
be an employee of the Employer during the Consulting Period, but shall act
solely in the capacity of an independent contractor.

         (ii) Consulting Fees, Reimbursement of Expenses. In consideration of
the Employee's agreement to provide consulting services hereunder, the Employer
shall pay the Employee, not less than 5 days following an Involuntary
Termination, a lump sum consulting fee payment equal to the product of (A) the
Employee's base salary in effect immediately prior to his Date of Termination
(without taking into account any salary reduction that gave rise to Good

<PAGE>   8

Reason), and (B) the number of years in the Consulting Period, as determined
pursuant to paragraph I 1 (a)(i) above. In addition, the Employee shall be
reimbursed for all expenses reasonably incurred by him in connection with the
performance of his consulting services hereunder. The Employee shall not be
entitled to benefits under any other severance pay plan or arrangement sponsored
by the Employer and its subsidiaries in the event of an Involuntary Termination
during the Covered Period, and any amounts payable to him under any statutory
severance policy shall reduce the aggregate amount of the consulting fees
payable hereunder. In addition, in the event of the Employee's Involuntary
Termination, the Employer shall pay him within 5 days of the date of such
Involuntary Termination the full amount of any earned but unpaid base salary
through the Date of Termination at the rate in effect at the time of the Notice
of Termination, plus a cash payment for all unused vacation time which he may
have accrued as of the Date of Termination. The Employer shall also pay the
Employee within 5 days of the Date of Termination a pro rata portion of his
projected annual bonus for the year in which his Involuntary Termination occurs,
calculated on the basis of his target bonus for that year.

         (iii) Benefits. The Employee and his eligible dependents shall continue
to be eligible to participate during the Consulting Period in the medical,
dental, health, life and other fringe benefit plans and arrangements applicable
to him immediately prior to his Involuntary Termination on the same terms and
conditions in effect for the Employee and his dependents immediately prior to
such Involuntary Termination; provided, however, that any benefit plan or
arrangement will end on the date that the Employee and his dependents are
eligible and elect coverage under a plan or arrangement of a subsequent employer
which provides a substantially equivalent or greater benefit to him and his
dependents.

         (iv) Date and Notice of Termination. Any termination of the Employee's
employment during the Covered Period by the Employer or by the Employee shall be
communicated by a notice of termination to the other party hereto (the "Notice
of Termination"). The Notice of Termination shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Employee's employment under the provision so indicated. The
date of the Employee's termination of employment with the Employer and its
subsidiaries (the "Date of Termination") shall be determined as follows-. (i) if
the Employee's employment is terminated by the Employer in an Involuntary
Termination, five (5) days after the date the Notice of Termination is received
by the Employee and (ii) if the Employee's employment is terminated by the
Employer for just cause, the date specified in the Notice of Termination. If the
basis for the Employee's Involuntary Termination is his resignation for Good
Reason, the Date of Termination shall be ten (10) days after the date his Notice
of Termination is received by the Employer. The Date of Termination for a
resignation of employment other than for Good Reason shall be the date set forth
in the applicable notice, which shall be no earlier than ten (10) days after the
date such notice is received by the Employer.

         (b) Non-Competition Agreement. During the Consulting Period, the
Employee shall comply with the substantive restrictions set forth in paragraphs
8 and 9 above.


<PAGE>   9

         (c) Legal Fees and Expenses. The Employer shall pay or reimburse the
Employee on an after-tax basis for all costs and expenses (including, without
limitations court costs and reasonable legal fees and expenses which reflect
common practice with respect to the matters involved) incurred by him as a
result of any claim, action or proceeding (i) arising out of his termination of
employment during the Covered Period, (ii) contesting, disputing or enforcing
any right, benefits or obligations under this paragraph 11 or (iii) arising out
of or challenging the validity, advisability or enforceability of this paragraph
11 or any provision thereof; provided, however, that this provision will not
apply if the trier of fact determines that the Employee's claim was entirely
without merit.

         (d) Definitions. For purposes of this paragraph 11, the following
capitalized words shall have the meanings set forth below:

         "Cause" shall mean a termination of the Employee's employment by the
Employer which is a result of (i) his felony conviction, (ii) his willful
disclosure of material trade secrets or other material confidential information
related to the business of the Employer and its subsidiaries or (iii) his
willful and continued failure substantially to perform his duties with the
Employer (other than any such failure resulting from his incapacity due to
physical or mental illness or any such actual or anticipated failure resulting
from a resignation by the Employee for Good Reason) after a written demand for
substantial performance is delivered to the Employee by the Board, which demand
specifically identifies the manner in which the Board believes that the Employee
has not substantially performed his duties, and which performance is not
substantially corrected by him within 10 days of receipt of such demand. For
purposes of the previous sentence, no act or failure to act on the Employee's
part shall be deemed "willful" unless done, or omitted to be done, by him not in
good faith and without reasonable belief that his action or omission was in the
best interest of the Employer. Notwithstanding the foregoing, the Employee shall
not be deemed to have been terminated for Cause unless and until there shall
have been delivered to him a copy of a resolution duly adopted by the
affirmative vote of not less than three-fourths (3/4ths) of the entire
membership of the Board at a meeting of the Board called and held for such
purpose (after reasonable notice to the Employee and an opportunity for him,
together with his counsel, to be heard before the Board), finding that in the
good faith opinion of the Board he was guilty of conduct set forth above in
clause (i), (ii) or (iii) of the first sentence of this definition and
specifying the particulars thereof in detail.

         "Change in Control" shall mean the happening of any of the following-

                  (i) any person or entity, including a "group" as defined in
         Section 13(d)(3) of the Exchange Act, other than the Employer, a
         subsidiary of the Employer, or any employee benefit plan of the
         Employer or its subsidiaries, becomes the beneficial owner of the
         Employer's securities having 25 percent or more of the combined voting
         power of the then outstanding securities of the Employer that may be
         cast for the election for directors of the Employer (other than as a
         result of an issuance of securities initiated by the Employer in the
         ordinary course of business); or


<PAGE>   10

                  (ii) as the result of, or in connection with, any cash tender
         or exchange offer, merger or other business combination, sale of assets
         or contested election, or any combination of the foregoing
         transactions, less than a majority of the combined voting power of the
         then outstanding securities of the Employer or any successor
         corporation or entity entitled to vote generally in the election of
         directors of the Employer or such other corporation or entity after
         such transaction, are held in the aggregate by holders of the
         Employer's securities entitled to vote generally in the election of
         directors of the Employer immediately prior to such transactions; or

                  (iii) during any period of two consecutive years, individuals
         who at the beginning of any such period constitute the Board cease for
         any reason to constitute at least a majority thereof, unless the
         election, or the nomination for election by the Employer's
         stockholders, of each director of the Employer first elected during
         such period was approved by a vote of at least two-thirds of the
         directors of the Employer then still in office who were directors of
         the Employer at the beginning of any such period (together, directors
         at the beginning of such period and new directors whose election or
         nomination was so approved are the "Incumbent Directors").

         "Change in Control Date" shall mean the date on which the Change in
Control occurs. Notwithstanding the first sentence of this section, if the
Employee's employment with the Employer terminates prior to the Change in
Control Date and it is reasonably demonstrated that his termination of
employment (i) was at the request of the third party who has taken steps
reasonably calculated to effect the Change in Control or (ii) otherwise arose in
connection with or in anticipation of the Change in Control, then Change in
Control Date shall mean the date immediately prior to the date of the Employee's
termination of employment.

         "Common Stock" shall mean the common stock of the Employer.

         "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended, and any successor provisions thereto.

         "Good Reason" shall mean a resignation by the Employee from his
employment with the Employer on or following the Change in Control Date as a
result of the occurrence of any of the following without his consent:

                  (i) A failure by the Employer to ensure that the Employee's
         position, titles, nature and status of responsibilities and reporting
         obligations are substantially equivalent to those that the Employee
         enjoyed immediately prior to the Change in Control Date, it being
         understood and agreed that such features shall not be deemed less than
         substantially equivalent solely by reason of the Employer ceasing to be
         a public company.

                  (ii) A reduction by the Employer in the Employee's annual base
         salary as in effect immediately prior to the Change in Control Date or
         as the same may be increased from time to time thereafter; a failure by
         the Employer to increase the Employee's salary at a rate commensurate
         with that of other key executives of the Employer; or a reduction 

<PAGE>   11

         in the Employee's target annual bonus (expressed as a percentage of
         base salary) below the target in effect for him prior to the Change in
         Control Date,

                  (iii) The relocation of the office of the Employer where the
         Employee is employed immediately prior to the Change in Control Date
         (the "CIC Location") to a location which is more than fifty (50) miles
         away from the CIC Location or the Employer's requiring the Employee to
         be based more than fifty (50) miles away from the CIC Location (except
         for required travel on the Employer's business to an extent
         substantially consistent with his customary business travel obligations
         in the ordinary course of business prior to the Change in Control
         Date), unless such relocation is to a location closer to his principal
         residence,

                  (iv) The failure by the Employer to continue in effect any
         compensation plan in which the Employee participated prior to the
         Change in Control Date or made available to him after the Change in
         Control Date, unless an equitable arrangement (embodied in an ongoing
         substitute or alternative plan) has been made with respect to such plan
         in connection with the Change in Control, or the failure by the
         Employer to continue the Employee's participation therein on at least
         as favorable a basis, both in terms of the amount of benefits provided
         and the level of his participation relative to other participants, as
         existed on the Change in Control Date;

                  (v) The failure by the Employer to continue to provide the
         Employee with benefits at least as favorable in the aggregate to those
         enjoyed by him under the Employer's pension, savings, life insurance,
         medical, health and accident, disability, and fringe benefit plans and
         programs in which he was participating immediately prior to the Change
         in Control Date; or the failure by the Employer to provide the Employee
         with the number of paid vacation days to which he is entitled on the
         basis of years of service with the Employer in accordance with the
         Employer's normal vacation policy in effect immediately prior to the
         Change in Control;

                  (vi) The failure of the Employer to obtain an agreement
         reasonably satisfactory to the Employee from any successor to assume
         and agree to perform this Agreement, as contemplated in paragraph 12(a)
         hereof or, if the business of the Employer for which the Employee's
         services are principally performed is sold at any time after a Change
         in Control, the failure of the Employer to obtain such an agreement
         from the purchaser of such business;

                  (vii) Any termination of the Employee's employment which is
         not effected pursuant to the terms of this Agreement; or

                  (viii) A material breach by the Employer of the provisions of
this Agreement;

provided, however, that an event described above in clause (i), (ii), (iv), (v)
or (viii) shall not constitute Good Reason unless it is communicated by the
Employee to the Employer in writing and is not corrected by the Employer in a
manner which is reasonably satisfactory to the 


<PAGE>   12

Employee (including full retroactive correction with respect to any monetary
matter) within 10 days of the Employer's receipt of such written notice from
him.

         "Involuntary Termination" shall mean (i) the termination of the
Employee's employment during the Covered Period by the Employer and its
subsidiaries other than for Cause or disability or (ii) the Employee's
resignation of employment during the Covered Period with the Employer and its
subsidiaries for Good Reason.

         12. Successors, Binding Agreement.

         (a) Assumption by Successor. The Employer will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Employer expressly to
assume and to agree to perform this Agreement in the same manner and to the same
extent that the Employer would be required to perform it if no such succession
had taken place; provided, however, that no such assumption shall relieve the
Employer of its obligations hereunder. As used in this Agreement, the "Employer"
shall mean the Employer as hereinbefore defined and any successor to its
business and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law or otherwise.

         (b) Enforceability, Beneficiaries. This Agreement shall be binding upon
and inure to the benefit of the Employee (and his personal representatives and
heirs) and the Employer and any organization which succeeds to substantially all
of the business or assets of the Employer, whether by means of merger,
consolidation, acquisition of all or substantially all of the assets of the
Employer or otherwise, including, without limitation, as a result of a Change in
Control or by operation of law. This Agreement shall inure to the benefit of and
be enforceable by the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Employee should die while any amount would still be payable to him hereunder if
he had continued to live, all such amounts, unless otherwise provided herein,
shall be paid in accordance with the terms of this Agreement to his devisee,
legatee or other designee or, if there is no such designee, to his estate.

         13. Notices. Any notice required or permitted to be given under this
Agreement shall be sufficient if in writing and delivered personally or sent by
registered mail (i) to Employee's residence, in the case of the Employee, or
(ii) to the business address of its President and Chief Executive Officer, in
the case of the Employer.

         14. Waiver of Breach and Severability. The waiver by the Employer of a
breach of any provision of this Agreement by the Employee shall not operate or
be construed as a waiver of any subsequent breach by the Employee. In the event
any provision of this Agreement is found to be invalid or unenforceable, it may
be severed from the Agreement and the remaining provision of the Agreement shall
continue to be binding and effective; provided, however, that, if possible, it
is the intention of the Employer and the Employee that such provision be
construed and interpreted as narrowly as necessary in order to make such
provision valid and enforceable.

<PAGE>   13

         15. Entire Agreement. This instrument and the letter agreement between
the Employee and the Employer dated January 1, 1996 contain the entire agreement
of the parties and supersede any prior understandings and agreements between
them respecting the subject matter of this Agreement, including, without
limitation, the Employment Agreement dated as of January 1, 1996. It may not be
changed orally, but only by an agreement in writing signed by the party against
whom enforcement of any waiver, change, modification,' extension or discharge is
sought.

         16. Survival. Upon termination of the Employee's employment with the
Company prior to a Change in Control Date, the rights and obligations of the
parties hereto as provided in paragraphs 8 and 9 shall continue for the time
periods as set forth herein.

         17. Governing Law. This Agreement shall be construed in accordance with
and governed by the laws of the State of Tennessee without regard to the laws of
any other state or jurisdiction. Any action brought or maintained in connection
with this Agreement shall be brought exclusively in the courts located in Shelby
County, Tennessee. Each of the Employer and the Employee hereby irrevocably
waives all right to trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement.

         IN WITNESS WHEREOF, the parties hereto execute this Agreement on the
date first above written.

         WHEREAS, the Board of Directors of the Employer (the "Board") has
concluded that it desires to engage the valued services of the Employee by

protections which are designed to ensure that the Employee will devote himself

covenants contained herein the parties agree as follows:

employs the Employee and the Employee hereby accepts employment upon the terms
and conditions hereinafter set forth.

         2. Term. Subject to the provisions for termination as provided in
paragraph 10 hereof, the term of this Agreement shall be from June 1, 1997 to
December 31, 2000, and it shall be automatically renewed for successive one (1)
year periods thereafter, unless either party elects not to renew this Agreement
by serving notice of such intention not to renew on the other party at least
ninety (90) days prior to the renewal date. Notwithstanding the foregoing, if a
Change in Control Date (as defined in paragraph I 1) occurs during the term
described in the immediately preceding sentence, the term of the Employee's

nominated each year for election as a director of the Company. With respect to
the options (the "Director Options") granted to the Employee in November 1994
under the Director Program of the Company's 1993 Long Term Incentive Plan, as
amended, such Director Options shall continue to vest in accordance with the
terms of such grant; provided that the Employee remains in the employ of the

         4. Extent of Services. The Employee shall have the power and authority
commensurate and necessary to his position of Group President-Operations, and

consent of the Employer, which consent shall not be unreasonably withheld,
during the term of this Agreement, be actively engaged in any other business
activity, whether or not such business activity is pursued for gain, profit and
other pecuniary advantage; but this shall not be construed as preventing the
Employee from (i) investing his personal assets in such form or manner as will
not require any services on the part of the Employee in the operation of the
affairs of the companies in which such investments are made or (ii) subject to
the restrictions on competition contained in paragraph 9 of this Agreement,

that upon the satisfaction of the eligibility period, the Company shall maintain
life insurance coverage on behalf of the Employee equal to two times the
Employee's annual salary. In addition to the foregoing, the Company shall
reimburse the Employee for the continuation of his current medical coverage
until such time as the Employee satisfies the 90-day eligibility period for the
medical plan maintained by the Company. Nothing herein shall be construed so as
to prevent the Employer from modifying or terminating any employee benefit plans

time to time.

by him in connection with his relocation to Memphis, Tennessee as described

disabled during the term of this Agreement to the extent that he shall be unable
to perform his duties and services for and on behalf of the Employer, the
benefits made available to the Employee and the salary then payable to the
Employee pursuant to the foregoing paragraph 5 shall continue to be made
available and paid to the Employee for the shorter of (i) the period of
disability; or (ii) six (6) months from the commencement of the disability.
Thereafter, the Employee shall receive no salary from the Employer.

         8. Confidentiality. The Employee possesses and will continue to possess
information which has been created, discovered, developed by or otherwise become
known to the Employee (including information discovered or made available by

rights have been assigned or otherwise conveyed to the Employer), which
information has commercial value to the Employer, including but not limited to
trade secrets, innovations, processes, computer codes, data, know-how,
improvements, discoveries, developments, techniques, marketing plans,
strategies, costs, customer and client lists, or any information the Employee
has reason to know the Employer would treat as confidential for any purpose,
whether or not developed by the Employee (hereinafter referred to as
"Confidential Information"). Unless previously authorized in writing or
instructed in writing by the Employer, the Employee will not, at any time,
disclose to others, or use, or allow anyone else to disclose or use any
Confidential Information (except as may be necessary in the performance of the
Employee's employment with the Employer), unless, until and then only to the
extent that such Confidential Information has become ascertainable or obtained
from public or published sources or was available to the Employee on a
non-confidential basis prior to any such disclosure or use, provided that the
source of such material is or was not bound by an

<PAGE>   5

obligation of confidentiality to the Employer. This paragraph 8 shall survive
termination of this Agreement.

         9. Restrictive Covenants. The terms of this paragraph 9 shall be
applicable during the Employee's employment and upon the termination of such
employment for any reason occurring prior to a Change in Control Date. In the
event of termination "without cause" as defined in paragraph 10(b) occurring
prior to a Change in Control Date, in consideration of, and subject to, the
Employee's continued compliance with the terms of this paragraph 9, the Employer
shall pay to the Employee (i) in the event such termination occurs during the
first year of the term of this Agreement, thirty-six months salary, (ii) in the
event such termination occurs during the second year of the term of this
Agreement, twenty-four months salary, and (iii) in the event such termination
occurs during the third year of the term of this Agreement or thereafter if the
term is extended pursuant to paragraph 2 of this Agreement, twelve months
salary. Salary shall be based on the Employee's salary for the month immediately
preceding the date of termination which shall be paid in accordance with the
Employer's customary payroll practices over the applicable period. In the event
of a termination for any other reason, including for "just cause" as defined in
paragraph 10(b) occurring prior to a Change in Control Date, the Employer shall
have no obligation to the Employee. This paragraph 9 shall survive termination
of this Agreement occurring prior to a Change in Control Date.

         The Employee acknowledges that because of his skills, the Employee's
position with the Employer and the Confidential Information to which the
Employee shall have access or be provided on account of such employment with the
Employer, competition by the Employee with the Employer could damage the
Employer in a manner which cannot adequately be compensated by damages or an
action at law. In view of such circumstances, because of the Confidential
Information obtained by, or disclosed to the Employee, and as a material
inducement to the Employer to enter into this Agreement and to compensate the
Employee, as described in paragraph 5, as well as provide him with additional
benefits as provided herein and other good and valuable consideration, the
Employee covenants and agrees that:

         (a) Noncompetition. During the Employee's employment with the Employer
and for a period of three (3) years thereafter, the Employee shall not (as
principal, agent, employee, consultant or otherwise), directly or indirectly, in
any geographic area in which the Employer is engaged in Business, engage in
activities for, or render services of any nature to, any firm or business, which
firm or business competes, directly or indirectly, with the Employer or the
Business.

         (b) Nonsolicitation of Customers. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit, divert or accept any work or services
which compete with the Employer's Business from any customer of the Employer or
seek to cause any such customer to refrain from doing business with or
patronizing the Employer.

         (c) Nonsolicitation of Employees, During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit for employment or employ any current or
former employee of the Employer.

         (d) Definitions. For purposes of this Agreement, the term "directly or
indirectly" shall be construed in its broadest sense and shall include the
activities of the members of the Employee's immediate family or any partnership.
The term "Business" shall be construed in its broadest sense and shall include
any activity engaged in or conducted by the Employer or any of its subsidiaries,
affiliates or joint ventures or which the Employer or any of its subsidiaries,
affiliates or joint ventures intends to engage in or conduct. The "customer"
shall mean any person or entity with which the Employer, or any of its
subsidiaries, affiliates or joint ventures has engaged in or conducted Business
during the one (1) year period prior to the date the Employee ceased employment
with the Employer or any persons or entities targeted by the Employer or
contacted for the purpose of engaging in or conducting Business during such one
(1) year period.

         (e) Reasonable Limitations. Given the important nature of the position
the Employee will hold with the Employer, the nature of the Employer's Business
and the sensitive nature of the Confidential Information and duties the Employee
will have with the Employer, the parties acknowledge that the limitations,
including but not limited to, the scope of activities prohibited, the geographic
area covered and the time limitation, are reasonable.

         In the event of an actual or threatened breach by the Employee of the
provisions of paragraphs 8 and 9 of this Agreement, the Employer shall be
entitled to a temporary restraining order and an injunction restraining the
Employee from such breach. Nothing herein, however, shall be construed as
prohibiting the Employer from pursuing any other remedies available to it for
such actual or threatened breach, including, without limitation, the recovery of
damages and reasonable attorneys' and paralegals' fees and costs from the
Employee. If the Employee violates any of the covenants in paragraphs 8 and 9 of
this Agreement, the term and the covenant violated shall be automatically
extended for the period of time of the violation, either from the date on which
the Employee ceases such violation or from the date of the entry by a court of
competent jurisdiction of an order or judgment enforcing such covenants,
whichever period is later.

         10. Termination Prior to a Change in Control Date, The Employer may, at
its option, terminate this Agreement at any time prior to the occurrence of a
Change in Control Date upon written notice to the Employee for just cause or
without cause.

         (a)      "Just cause" shall include, but not be limited to:

                  (i)     The Employee's misuse or embezzlement of funds
                          belonging to the Employer, conviction of a felony or
                          crime involving moral turpitude or use of alcohol or
                          drugs in such a manner as will injure or adversely
                          affect the reputation of the Employer or its
                          employees, customers, agents, officers or directors;

<PAGE>   7

                  (ii)    The Employee's absence from his employment, for
                          whatever cause, other than by disability for which
                          salary is continued pursuant to paragraph 7, for a
                          period of thirty (30) consecutive days or more;

                  (iii)   The Employee's absence from employment as a result of
                          disability beyond the period for which salary is
                          continued pursuant to paragraph 7;

                  (iv)    The Employee's resignation from employment during the
                          term hereof or if the Employee serves notice to not
                          renew this Agreement as provided in paragraph 2;

                  (v)     The Employee's willful malfeasance in discharging his
                          obligations hereunder and such acts and their
                          consequences are not remedied within ten (10) days or
                          such longer reasonable period of time designated by
                          the Employer after written notice thereof has been
                          given to the Employee; or

                  (vi)    The Employee's breach of the provisions of this
                          Agreement and such breach and its consequences are not
                          remedied within ten (10) days or such longer
                          reasonable period of time designated by the Employer,
                          after written notice thereof has been given to the
                          Employee.

         (b)      "Without cause" shall mean:

                  (i)     The termination and dissolution of the Employer or a 
                          bona fide decision by the Employer to terminate its
                          Business; or

                  (ii)    Any involuntary termination of the Employee's
                          employment by the Employer without just cause.

         (c) In addition to those reasons enumerated above, this Agreement shall
be terminated upon the happening of any of the following events:

                  (i)     Whenever the Employer and the Employee shall mutually 
                          agree to a termination in writing; or

                  (ii)    Upon death of the Employee.

Upon the termination of this Agreement prior to the occurrence of a Change in
Control Date for any of the foregoing reasons in paragraph 10, the Employee
shall be entitled to receive only the compensation accrued but unpaid as of the
date of the termination hereof and shall not be entitled to additional
compensation except as expressly provided in paragraph 9 of this Agreement.

         11. Effect of a Change in Control.

         (a) Involuntary Termination; Consulting Period.

<PAGE>   8


         (i) Consulting Services Following an Involuntary Termination. In the
event of the Employee's Involuntary Termination during the Covered Period he
shall commence providing consulting services to the Employer for a period (the
"Consulting Period") of (i) three years, in the event the Involuntary
Termination occurs during the first year of the Covered Period, (ii) two years,
in the event the Involuntary Termination occurs during the second year of the
Covered Period, or (iii) one year, in the event the Involuntary Termination
occurs in the last year of the Covered Period. The Employee's consulting
services shall consist in advising the Employer on such matters as may be
reasonably requested by the Employer. Such services shall be performed at such
times and in such locations as shall be mutually agreed by the Employee and the
Employer, and shall not interfere with his duties to a new employer. In any
event, the Employee shall not be required to perform consulting services for
more than 8 hours per month during the Consulting Period. The Employee shall not
be an employee of the Employer during the Consulting Period, but shall act
solely in the capacity of an independent contractor.

         (ii) Consulting Fees; Reimbursement of Expenses. In consideration of
the Employee's agreement to provide consulting services hereunder, the Employer
shall pay the Employee, not less than 5 days following an Involuntary
Termination, a lump sum consulting fee payment equal to the product of (A) the
Employee's base salary in effect immediately prior to his Date of Termination
(without taking into account any salary reduction that gave rise to Good
Reason), and (B) the number of years in the Consulting Period, as determined
pursuant to paragraph II (a)(i) above. In addition, the Employee shall be
reimbursed for all expenses reasonably incurred by him in connection with the
performance of his consulting services hereunder. The Employee shall not be
entitled to benefits under any other severance pay plan or arrangement sponsored
by the Employer and its subsidiaries in the event of an Involuntary Termination
during the Covered Period, and any amounts payable to him under any statutory
severance policy shall reduce the aggregate amount of the consulting fees
payable hereunder. In addition, in the event of the Employee's Involuntary
Termination, the Employer shall pay him within 5 days of the date of such
Involuntary Termination the full amount of any earned but unpaid base salary
through the Date of Termination at the rate in effect at the time of the Notice
of Termination, plus a cash payment for all unused vacation time which he may
have accrued as of the Date of Termination. The Employer shall also pay the
Employee within 5 days of the Date of Termination a pro rata portion of his
projected annual bonus for the year in which his Involuntary Termination occurs,
calculated on the basis of his target bonus for that year.

         (iii) Benefits. The Employee and his eligible dependents shall continue
to be eligible to participate during the Consulting Period in the medical,
dental, health, life and other fringe benefit plans and arrangements applicable
to him immediately prior to his Involuntary Termination on the same terms and
conditions in effect for the Employee and his dependents immediately prior to
such Involuntary Termination; provided, however, that any benefit plan or
arrangement will end on the date that the Employee and his dependents are
eligible and elect coverage under a plan or arrangement of a subsequent employer
which provides a substantially equivalent or greater benefit to him and his
dependents,

<PAGE>   9

         (iv) Date and Notice of Termination, Any termination of the Employee's
employment during the Covered Period by the Employer or by the Employee shall be
communicated by a notice of termination to the other party hereto (the "Notice
of Termination"). The Notice of Termination shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Employee's employment under the provision so indicated. The
date of the Employee's termination of employment with the Employer and its
subsidiaries (the "Date of Termination") shall be determined as follows: (i) if
the Employee's employment is terminated by the Employer in an Involuntary
Termination, five (5) days after the date the Notice of Termination is received
by the Employee and (ii) if the Employee's employment is terminated by the
Employer for just cause, the date specified in the Notice of Termination, If the
basis for the Employee's Involuntary Termination is his resignation for Good
Reason, the Date of Termination shall be ten (10) days after the date his Notice
of Termination is received by the Employer. The Date of Termination for a
resignation of employment other than for Good Reason shall be the date set forth
in the applicable notice, which shall be no earlier than ten (10) days after the
date such notice is received by the Employer.

         (b) Non-Competition Agreement, During the Consulting Period, the
Employee shall comply with the substantive restrictions set forth in paragraphs
8 and 9 above.

         (c) Legal Fees and Expenses. The Employer shall pay or reimburse the
Employee on an after-tax basis for all costs and expenses (including, without
limitation, court costs and reasonable legal fees and expenses which reflect
common practice with respect to the matters involved) incurred by him as a
result of any claim, action or proceeding (i) arising out of his termination of
employment during the Covered Period, (ii) contesting, disputing or enforcing
any right, benefits or obligations under this paragraph 11 or (iii) arising out
of or challenging the validity, advisability or enforceability of this paragraph
11 or any provision thereof; provided, however, that this provision will not
apply if the trier of fact determines that the Employee's claim was entirely
without merit.

         (d) Definitions. For purposes of this paragraph 11, the following
capitalized words shall have the meanings set forth below:

         "Cause" shall mean a termination of the Employee's employment by the
Employer which is a result of (i) his felony conviction, (ii) his willful
disclosure of material trade secrets or other material confidential information
related to the business of the Employer and its subsidiaries or (iii) his
willful and continued failure substantially to perform his duties with the
Employer (other than any such failure resulting from his incapacity due to
physical or mental illness or any such actual or anticipated failure resulting
from a resignation by the Employee for Good Reason) after a written demand for
substantial performance is delivered to the Employee by the Board, which demand
specifically identifies the manner in which the Board believes that the Employee
has not substantially performed his duties, and which performance is not
substantially corrected by him within 10 days of receipt of such demand. For
purposes of the previous sentence, no act or failure to act on the Employee's
part shall be deemed "willful" unless done, or omitted to be done, by him not in
good faith and without reasonable belief that his action or omission was in

<PAGE>   10

the best interest of the Employer, Notwithstanding the foregoing, the Employee
shall not be deemed to have been terminated for Cause unless and until there
shall have been delivered to him a copy of a resolution duty adopted by the
affirmative vote of not less than three-fourths (3/4ths) of the entire
membership of the Board at a meeting of the Board called and held for such
purpose (after reasonable notice to the Employee and an opportunity for him,
together with his counsel, to be heard before the Board), finding that in the
good faith opinion of the Board he was guilty of conduct set forth above in
clause (i), (ii) or (iii) of the first sentence of this definition and
specifying the particulars thereof in detail.

         "Change in Control" shall mean the happening of any of the following:

                  (i) any person or entity, including a "group" as defined in
         Section 13(d)(3) of the Exchange Act, other than the Employer, a
         subsidiary of the Employer, or any employee benefit plan of the
         Employer or its subsidiaries, becomes the beneficial owner of the
         Employer's securities having 25 percent or more of the combined voting
         power of the then outstanding securities of the Employer that may be
         cast for the election for directors of the Employer (other than as a
         result of an issuance of securities initiated by the Employer in the
         ordinary course of business); or

                  (ii) as the result of, or in connection with, any cash tender
         or exchange offer, merger or other business combination, sale of assets
         or contested election, or any combination of the foregoing
         transactions, less than a majority of the combined voting power of the
         then outstanding securities of the Employer or any successor
         corporation or entity entitled to vote generally in the election of
         directors of tile Employer or such other corporation or entity after
         such transaction, are held in the aggregate by holders of the
         Employer's securities entitled to vote generally in the election of
         directors of the Employer immediately prior to such transactions; or

                  (iii) during any period of two consecutive years, individuals
         who at the beginning of any such period constitute the Board cease for
         any reason to constitute at least a majority thereof, unless the
         election, or the nomination for election by the Employer's
         stockholders, of each director of the Employer first elected during
         such period was approved by a vote of at least two-thirds of the
         directors of the Employer then still in office who were directors of
         the Employer at the beginning of any such period (together, directors
         at the beginning of such period and new directors whose election or
         nomination was so approved are the "Incumbent Directors"),

         "Change in Control Date" shall mean the date on which the Change in
Control occurs. Notwithstanding the first sentence of this paragraph, if the
Employee's employment with the Employer terminates prior to the Change in
Control Date and it is reasonably demonstrated that his termination of
employment (i) was at the request of the third party who has taken steps
reasonably calculated to effect the Change in Control or (ii) otherwise arose in
connection with or in anticipation of the Change in Control, then Change in
Control Date shall mean the date immediately prior to the date of the Employee's
termination of employment,


<PAGE>   11

         "Common Stock" shall mean the common stock of the Employer.

         "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended, and any successor provisions thereto.

         "Good Reason" shall mean a resignation by the Employee from his
employment with the Employer on or following the Change in Control Date as a
result of the occurrence of any of the following without his consent:

                  (i) A failure by the Employer to ensure that the Employee's
         position, titles, nature and status of responsibilities and reporting
         obligations are substantially equivalent to those that the Employee
         enjoyed immediately prior to the Change in Control Date, it being
         understood and agreed that such features shall be deemed less than
         substantially equivalent by reason of the Employer ceasing to be a
         public company.

                  (ii) A reduction by the Employer in the Employee's annual base
         salary as in effect immediately prior to the Change in Control Date or
         as the same may be increased from time to time thereafter; a failure by
         the Employer to increase the Employee's salary at a rate commensurate
         with that of other key executives of the Employer; or a reduction IN
         the Employee's target annual bonus (expressed as a percentage of base
         salary) below the target in effect for him prior to the Change in
         Control Date;

                  (iii) The relocation of the office of the Employer where the
         Employee is employed immediately prior to the Change in Control Date
         (the "CIC Location") to a location which is more than fifty (50) miles
         away from the CIC Location or the Employer's requiring the Employee to
         be based more than fifty (50) miles away from the CIC Location (except
         for required travel on the Employer's business to an extent
         substantially consistent with his customary business travel obligations
         in the ordinary course of business prior to the Change in Control
         Date), unless such relocation is to a location closer to his principal
         residence;

                  (iv) The failure by the Employer to continue in effect any
         compensation plan in which the Employee participated prior to the
         Change in Control Date or made available to him after the Change in
         Control Date, unless an equitable arrangement (embodied in an ongoing
         substitute or alternative plan) has been made with respect to such plan
         in connection with the Change in Control, or the failure by the
         Employer to continue the Employee's participation therein on at least
         as favorable a basis, both in terms of the amount of benefits provided
         and the level of his participation relative to other participants, as
         existed on the Change in Control Date;

                  (v) The failure by the Employer to continue to provide the
         Employee with benefits at least as favorable in the aggregate to those
         enjoyed by him under the Employer's pension, savings, life insurance,
         medical, health and accident, disability, and fringe benefit plans and
         programs in which he was participating immediately prior to the Change
         in Control Date; or the failure by the Employer to provide the Employee
         with the 


<PAGE>   12

         number of paid vacation days to which he is entitled to under this
         Agreement or on the basis of years of service with the Employer in
         accordance with the Employer's normal vacation policy in effect
         immediately prior to the Change in Control, whichever is greater;

                  (vi) The failure of the Employer to obtain an agreement
         reasonably satisfactory to the Employee from any successor to assume
         and agree to perform this Agreement, as contemplated in paragraph 12(a)
         hereof or, if the business of the Employer for which the Employee's
         services are principally performed is sold at any time after a Change
         in Control, the failure of the Employer to obtain such an agreement
         from the purchaser of such business;

                  (vii) Any termination of the Employee's employment which is
         not effected pursuant to the terms of this Agreement; or

                  (viii) A material breach by the Employer of the provisions of
         this Agreement;

provided, however, that an event described above in clause (1), (ii), (iv), (v)
or (viii) shall not constitute Good Reason unless it is communicated by the
Employee to the Employer in writing and is not corrected by the Employer in a
manner which is reasonably satisfactory to the Employee (including full
retroactive correction with respect to any monetary matter) within 10 days of
the Employer's receipt of such written notice from him.

         "Involuntary Termination" shall mean (1) the termination of the
Employee's employment during the Covered Period by the Employer and its
subsidiaries other than for Cause or disability or (ii) the Employee's
resignation of employment during the Covered Period with the Employer and its
subsidiaries for Good Reason.

         12. Successors; Binding Agreement.

         (a) Assumption by Successor. The Employer will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Employer expressly to
assume and to agree to perform this Agreement in the same manner and to the same
extent that the Employer would be required to perform it if no such succession
had taken place; provided, however, that no such assumption shall relieve the
Employer of its obligations hereunder. As used in this Agreement, the "Employer"
shall mean the Employer as hereinbefore defined and any successor to its
business and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law or otherwise.

         (b) Enforceability; Beneficiaries. This Agreement shall be binding upon
and inure to the benefit of the Employee (and his personal representatives and
heirs) and the Employer and any organization which succeeds to substantially all
of the business or assets of the Employer, whether by means of merger,
consolidation, acquisition of all or substantially all of the assets of the
Employer or otherwise, including, without limitation, as a result of a Change in
Control or by 


<PAGE>   13

operation of law. This Agreement shall inure to the benefit of and be
enforceable by the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Employee should die while any amount would still be payable to him hereunder if
he had continued to live, all such amounts, unless otherwise provided herein,
shall he paid in accordance with the terms of this Agreement to his devisee,
legatee or other designee or, if there is no such designee, to his estate.

         13. Notices. Any notice required or permitted to be given under this
Agreement shall be sufficient if in writing and delivered personally or sent by
registered mail (i) to Employee's residence, in the case of the Employee, or
(ii) to the business address of its President and Chief Executive Officer, in
the case of the Employer.

         14. Waiver of Breach and Severability. The waiver by the Employer of a
breach of any provision of this Agreement by the Employee shall not operate or
be construed as a waiver of any subsequent breach by the Employee, In the event
any provision of this Agreement is found to be invalid or unenforceable, it may
be severed from the Agreement and the remaining provision of the Agreement shall
continue to be binding and effective; provided, however, that, if possible, it
is the intention of the Employer and the Employee that such provision be
construed and interpreted as narrowly as necessary in order to make such
provision valid and enforceable.

         15. Entire Agreement. This Agreement, the section relating to
Relocation contained in the April 4th letter and the letter agreement between
the Employee and the Employer dated as of the date hereof contain the entire
agreement of the parties and supersede any prior understandings and agreements
between them respecting the subject matter of this Agreement. It may not be
changed orally, but only by an agreement in writing signed by the party against
whom enforcement of any waiver, change, modification, extension or discharge is
sought.

         16. Survival. Upon termination of the Employee's employment with the
Company prior to a Change in Control Date, the rights and obligations of the
parties hereto as provided in paragraphs 8 and 9 shall continue for the time
periods as set forth herein.

         17. Governing Law. This Agreement shall be construed in accordance with
and governed by the laws of the State of Tennessee without regard to the laws of
any other state or jurisdiction. Any action brought or maintained in connection
with this Agreement shall be brought exclusively in the courts located in Shelby
County, Tennessee. Each of the Employer and the Employee hereby irrevocably
waives all right to trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement.

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         AMENDED AND RESTATED EMPLOYMENT AGREEMENT, dated as of the 27th day of
April, 1997, between SOFAMOR DANEK GROUP, INC., an Indiana corporation (the
"Employer"), and John Pafford (the "Employee").

                                    RECITALS

         WHEREAS, the Employer is an Indiana corporation and through its wholly
owned subsidiaries, Warsaw Orthopedic, Inc., Danek Medical, Inc., and Sofamor,
S.N.C. is engaged in the business of developing, manufacturing and distributing
medical devices, trauma instruments, surgical tools and implants (such business,
as it may change from time to time, is hereinafter referred to as "Business");
and

         WHEREAS, the Board of Directors of the Employer (the "Board") has
concluded that it desires to retain the valued services of the Employee by
entering into a new agreement which shall provide the Employee with certain
additional protections which are designed to ensure that the Employee will
devote himself attentively and energetically to his duties without distraction;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants contained herein, the parties agree as follows:

         1. Employment. The Employer (or a subsidiary of the Employer) hereby 
employs the Employee and the Employee hereby accepts employment upon the terms
and conditions hereinafter set forth.

         2. Term. Subject to the provisions for termination as provided in
paragraph 10 hereof, the term of this Agreement shall be from April 29, 1997 to
December 31, 1999, and it shall be automatically renewed for successive one (1)
year periods thereafter, unless either party elects not to renew this Agreement
by serving notice of such intention not to renew on the other party at least
ninety (90) days prior to the renewal date. Notwithstanding the foregoing, if a
Change in Control Date (as defined in paragraph II) occurs during the term
described in the immediately preceding sentence, the term of the Employee's
employment hereunder shall extend until the third anniversary of such Change in
Control Date (the period beginning on such Change in Control Date and ending on
the third anniversary thereof being hereinafter referred to as the "Covered
Period").

         3. Duties. The Employee is engaged as Vice President, U.S. Product
Development of the Employer to assist the President and CEO of the Employer in
managing, directing and administering all aspects and matters of the Business,
subject to the direction and guidance of the President and CEO of the Employer.
Prior to a Change in Control (as hereinafter defined), the precise services,
duties and authority of the Employee as Vice President, U.S. Product

<PAGE>   3

Development of the Employer may be further defined, extended or curtailed from
time to time at the discretion of the President and CEO of the Employer.

         4. Extent of Services. The Employee shall have the power and authority
commensurate and necessary to his position of Vice President, U.S. Product
Development and his other duties as assigned to him from time to time. He shall
devote his entire employable time, attention and best efforts to the Business as
may be necessary to efficiently and effectively perform and complete the duties
he is to undertake as described in this Agreement. The Employee shall not,
without the consent of the Employer, which consent shall not be unreasonably
withheld, during the term of this Agreement, be actively engaged in any other
business activity, whether or not such business activity is pursued for gain,
profit and other pecuniary advantage; but this shall not be construed as
preventing the Employee from investing his personal assets in such form or
manner as will not require any services on the part of the Employee in the
operation of the affairs of the companies in which such investments are made.

         5. Compensation. The Employee shall be compensated for services
rendered hereunder as follows:

         (a) The Employee shall receive a salary of not less than $15,000 per
month for each month of the first twelve (12) months that this Agreement is in
effect and for each month thereafter so long as the Employee receives Job
Performance Evaluations of "good" or better. After such first year, if the
Employee receives a Job Performance Evaluation of less than "good", his salary
shall be determined in the discretion of the President and CEO of the Employer.
Such salary paid to the Employee shall be subject to withholding of taxes and
other appropriate and customary amounts.

         (b) The Employee shall be entitled to participate in the employee
benefit plans the Employer may adopt from time to time for its management or
supervisory personnel generally at such time as the Employee shall have
fulfilled the eligibility requirements for participation therein as shall be
determined by the terms of the applicable contracts for each program. Nothing
herein shall be construed so as to prevent the Employer from modifying or
terminating any employee benefit plans or programs or employee fringe benefits
it currently sponsors or may adopt from time to time.

         6. Expenses and Travel. It is expected that in the course of his
employment, the Employee and his spouse shall be required to spend time
traveling and entertaining various persons on behalf of the Employer and
promoting the affairs of the Employer. The Employer shall provide to the
Employee an Employer Mastercard credit card or the Employer shall pay the
Employee the annual fee for one (1) personal credit card. The Employer shall pay
for or reimburse the Employee for all such reasonable expenses upon the
Employee's periodic presentation of an itemized account of such expenditures,
provided, however, the Employer shall only pay for or reimburse for the cost of
coach class air fare for business travel within the United States and only for
the cost of business class air fare for international business air travel. The
Employer shall bear the expense, in an amount not to exceed $250 per month, for
country club or social club dues for which the Employee may become a member
during the term hereof and/or a


<PAGE>   4

portable telephone and related telephone service, the use of either of which is
related to the Business. The Employee shall bear the expense of any initiation
fees and other assessments for or resulting from such membership. The Employee
shall be reimbursed in an amount not to exceed a total of $2,000 for each year
during the term or any renewal term hereof, for expenses incurred for his spouse
when traveling with the Employee on business matters for the Employer.

         7. Disability. If the Employee shall become physically or mentally
disabled during the term of this Agreement to the extent that he shall be unable
to perform his duties and services for and on behalf of the Employer, the
benefits made available to the Employee and the salary then payable to the
Employee pursuant to the foregoing paragraph 5 shall continue to be made
available and paid to the Employee for the shorter of (i) the period of
disability; or (ii) six (6) months from the commencement of the disability.
Thereafter, the Employee shall receive no salary from the Employer.

         8. Confidentiality. The Employee possesses and will continue to possess
information which has been created, discovered, developed by or otherwise become
known to the Employee (including information discovered or made available by
subsidiaries, affiliates or joint ventures of the Employer or in which property
rights have been assigned or otherwise conveyed to the Employer), which
information has commercial value to the Employer, including but not limited to
trade secrets, innovations, processes, computer codes, data, know-how,
improvements, discoveries, developments, techniques, marketing plans,
strategies, costs, customer and client lists, or any information the Employee
has reason to know the Employer would treat as confidential for any purpose,
whether or not developed by the Employee (hereinafter referred to as
"Confidential Information"). Unless previously authorized in writing or
instructed in writing by the Employer, the Employee will not, at any time,
disclose to others, or use, or allow anyone else to disclose or use any
Confidential Information (except as may be necessary in the performance of the
Employee's employment with the Employer), unless, until and then only to the
extent that such Confidential Information has become ascertainable or obtained
from public or published sources or was available to the Employee on a
non-confidential basis prior to any such disclosure or use, provided that the
source of such material is or was not bound by an obligation of confidentiality
to the Employer. This paragraph 8 shall survive termination of this Agreement.

         9. Restrictive Covenants. The terms of this paragraph 9 shall be
applicable during the Employee's employment and upon the termination of such
employment for any reason occurring prior to a Change in Control Date, In the
event of termination "without cause" as defined in paragraph 10(b) occurring
prior to a Change in Control Date, in consideration of, and subject to, the
Employee's continued compliance with the terms of this paragraph 9, the Employer
shall pay to the Employee twelve (12) months salary based on his salary for the
month immediately preceding the date of termination which shall be paid in
accordance with the Employer's customary payroll practices over twelve (12)
months. In the event of a termination for any other reason, including for "just
cause" as defined in paragraph 10(b) occurring prior to a Change in Control
Date, the Employer shall have no obligation to the Employee. This paragraph 9
shall survive termination of this Agreement occurring prior to a Change in
Control Date.

         The Employee acknowledges that because of his skills, the Employee's
position with the Employer and the Confidential Information to which the
Employee shall have access or be provided on account of such employment with the
Employer, competition by the Employee with the Employer could damage the
Employer in a manner which cannot adequately be compensated by damages or an
action at law. In view of such circumstances, because of the Confidential
Information obtained by, or disclosed to the Employee, and as a material
inducement to the Employer to enter into this Agreement and to compensate the
Employee, as described in paragraph 5, as well as provide him with additional
benefits as provided herein and other good and valuable consideration, the
Employee covenants and agrees that:

         (a) Noncompetition. During the Employee's employment with the Employer
and for a period of three (3) years thereafter, the Employee shall not (as
principal, agent, employee, consultant or otherwise), directly or indirectly, in
any geographic area in which the Employer is engaged in Business, engage in
activities for, or render services of any nature to, any firm or business, which
firm or business competes, directly or indirectly, with the Employer or the
Business.

         (b) Nonsolicitation of Customers. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit, divert or accept any work or services
which compete with the Employer's Business from any customer of the Employer or
seek to cause any such customer to refrain from doing business with or
patronizing the Employer.

         (c) Nonsolicitation of Employees. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit for employment or employ any current or
former employee of the Employer.

         (d) Definitions. For purposes of this Agreement, the term "directly or
indirectly" shall be construed in its broadest sense and shall include the
activities of the members of the Employee's immediate family or any partnership.
The term "Business" shall be construed in its broadest sense and shall include
any activity engaged in or conducted by the Employer or any of its subsidiaries,
affiliates or joint ventures or which the Employer or any of its subsidiaries,
affiliates or joint ventures intends to engage in or conduct. The term
"customer" shall mean any person or entity with which the Employer, or any of
its subsidiaries, affiliates or joint ventures has engaged in or conducted
Business during the one (1) year period prior to the date the Employee ceased
employment with the Employer or any persons or entities targeted by the Employer
or contacted for the purpose of engaging in or conducting Business during such
one (1) year period.

         (e) Reasonable Limitations. Given the important nature of the position
the Employee will hold with the Employer, the nature of the Employer's Business
and the sensitive nature of the Confidential Information and duties the Employee
will have with the Employer, the parties acknowledge that the limitations,
including but not limited to, the scope of activities prohibited, the geographic
area covered and the time limitation, are reasonable.

         In the event of an actual or threatened breach by the Employee of the
provisions of paragraphs 8 and 9 of this Agreement, the Employer shall be
entitled to a temporary restraining order and an injunction restraining the
Employee from such breach. Nothing herein, however, shall be construed as
prohibiting the Employer from pursuing any other remedies available to it for
such actual or threatened breach, including, without limitation, the recovery of
damages and reasonable attorneys' and paralegals' fees and costs from the
Employee, If the Employee violates any of the covenants in paragraphs 8 and 9 of
this Agreement, the term and the covenant violated shall be automatically
extended for the period of time of the violation, either from the date on which
the Employee ceases such violation or from the date of the entry by a court of
competent jurisdiction of an order or judgment enforcing such covenants,
whichever period is later.

         10. Termination Prior to a Change in Control Date. The Employer may, at
its option, terminate this Agreement at any time prior to the occurrence of a
Change in Control Date upon written notice to the Employee for just cause or
without cause.

         (a)      "Just cause" shall include, but not be limited to:

                  (i)     The Employee receiving a Job Performance Evaluation of
                          less than "good";

                  (ii)    The Employee's misuse or embezzlement of funds
                          belonging to the Employer, conviction of a felony or
                          crime involving moral turpitude or use of alcohol or
                          drugs in such a manner as will injure or adversely
                          affect the reputation of the Employer or its
                          employees, customers, agents, officers or directors;

                  (iii)   The Employee's absence from his employment, for
                          whatever cause, other than by disability for which
                          salary is continued pursuant to paragraph 7, for a
                          period of thirty (30) consecutive days or more;

                  (iv)    The Employee's absence from employment as a result of

                          continued pursuant to paragraph 7;

                  (v)     The Employee's resignation from employment during the
                          term hereof or if the Employee serves notice to not
                          renew this Agreement as provided in paragraph 2;

                  (vi)    The Employee's willful malfeasance in discharging his
                          obligations hereunder and such acts and their
                          consequences are not remedied within ten (10) days or
                          such longer reasonable period of time designated by
                          the Employer after written notice thereof has been
                          given to the Employee; or

                  (vii)   The Employee's breach of the provisions of this
                          Agreement and such breach and its consequences are not
                          remedied within ten (10) days or such longer
                          reasonable period of time designated by the Employer,
                          after written notice thereof has been given to the
                          Employee.

<PAGE>   7

         (b)      "Without cause" shall mean:

                  (i)     The termination and dissolution of the Employer or a
                          bona fide decision by the Employer to terminate its 
                          Business; or

                  (ii)    Any involuntary termination of the Employee's
                          employment by the Employer without just cause.

         (c) In addition to those reasons enumerated above, this Agreement shall
be terminated upon the happening of any of the following events:

                  (i)     Whenever the Employer and the Employee shall mutually 
                          agree to a termination in writing; or

                  (ii)    Upon death of the Employee.

Upon the termination of this Agreement prior to the occurrence of a Change in
Control Date for any of the foregoing reasons in paragraph 10, the Employee
shall be entitled to receive only the compensation accrued but unpaid as of the
date of the termination hereof and shall not be entitled to additional
compensation except as expressly provided in paragraph 9 of this Agreement.

         11. Effect of a Change in Control.

         (a) Involuntary Termination, Consulting Period.

         (i) Consulting Services Following an Involuntary Termination. In the
event of the Employee's Involuntary Termination during the Covered Period he
shall commence providing consulting services to the Employer for a period (the
"Consulting Period") of (i) three years, in the event the Involuntary
Termination occurs during the first year of the Covered Period, (ii) two years,
in the event the Involuntary Termination occurs during the second year of the
Covered Period, or (iii) one year, in the event the Involuntary Termination
occurs in the last year of the Covered Period. The Employee's consulting
services shall consist in advising the Employer on such matters as may be
reasonably requested by the Employer. Such services shall be performed at such
times and in such locations as shall be mutually agreed by the Employee and the
Employer, and shall not interfere with his duties to a new employer. In any
event, the Employee shall not be required to perform consulting services for
more than 8 hours per month during the Consulting Period. The Employee shall not
be an employee of the Employer during the Consulting Period, but shall act
solely in the capacity of an independent contractor.

         (ii) Consulting Fees, Reimbursement of Expenses. In consideration of
the Employee's agreement to provide consulting services hereunder, the Employer
shall pay the Employee, not less than 5 days following an Involuntary
Termination, a lump sum consulting fee payment equal to the product of (A) the
Employee's base salary in effect immediately prior to his Date of Termination
(without taking into account any salary reduction that gave rise to Good

<PAGE>   8


Reason), and (B) the number of years in the Consulting Period, as determined
pursuant to paragraph II (a)(i) above. In addition, the Employee shall be
reimbursed for all expenses reasonably incurred by him in connection with the
performance of his consulting services hereunder. The Employee shall not be
entitled to benefits under any other severance pay plan or arrangement sponsored
by the Employer and its subsidiaries in the event of an Involuntary Termination
during the Covered Period, and any amounts payable to him under any statutory
severance policy shall reduce the aggregate amount of the consulting fees
payable hereunder. In addition, in the event of the Employee's Involuntary
Termination, the Employer shall pay him within 5 days of the date of such
Involuntary Termination the full amount of any earned but unpaid base salary
through the Date of Termination at the rate in effect at the time of the Notice
of Termination, plus a cash payment for all unused vacation time which he may
have accrued as of the Date of Termination. The Employer shall also pay the
Employee within 5 days of the Date of Termination a pro rata portion of his
projected annual bonus for the year in which his Involuntary Termination occurs,
calculated on the basis of his target bonus for that year.

         (iii) Benefits. The Employee and his eligible dependents shall continue
to be eligible to participate during the Consulting Period in the medical,
dental, health, life and other fringe benefit plans and arrangements applicable
to him immediately prior to his Involuntary Termination on the same terms and
conditions in effect for the Employee and his dependents immediately prior to
such Involuntary Termination; provided, however, that any benefit plan or
arrangement will end on the date that the Employee and his dependents are
eligible and elect coverage under a plan or arrangement of a subsequent employer
which provides a substantially equivalent or greater benefit to him and his
dependents.

         (iv) Date and Notice of Termination. Any termination of the Employee's
employment during the Covered Period by the Employer or by the Employee shall be
communicated by a notice of termination to the other party hereto (the "Notice
of Termination"). The Notice of Termination shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Employee's employment under the provision so indicated. The
date of the Employee's termination of employment with the Employer and its
subsidiaries (the "Date of Termination") shall be determined as follows: (i) if
the Employee's employment is terminated by the Employer in an Involuntary
Termination, five (5) days after the date the Notice of Termination is received
by the Employee and (ii) if the Employee's employment is terminated by the
Employer for just cause, the date specified in the Notice of Termination. If the
basis for the Employee's Involuntary Termination is his resignation for Good
Reason, the Date of Termination shall be ten (10) days after the date his Notice
of Termination is received by the Employer. The Date of Termination for a
resignation of employment other than for Good Reason shall be the date set forth
in the applicable notice, which shall be no earlier than ten (10) days after the
date such notice is received by the Employer.

         (b) Non-Competition Agreement. During the Consulting Period, the
Employee shall comply with the substantive restrictions set forth in paragraphs
8 and 9 above.

<PAGE>   9

         (c) Legal Fees and Expenses. The Employer shall pay or reimburse the
Employee on an after-tax basis for all costs and expenses (including, without
limitation, court costs and reasonable legal fees and expenses which reflect
common practice with respect to the matters involved) incurred by him as a
result of any claim, action or proceeding (i) arising out of his termination of
employment during the Covered Period, (ii) contesting, disputing or enforcing
any right, benefits or obligations under this paragraph 11 or (iii) arising out
of or challenging the validity, advisability or enforceability of this paragraph
11 or any provision thereof- provided, however, that this provision will not
apply if the trier of fact determines that the Employee's claim was entirely
without merit.

         (d) Definitions. For purposes of this paragraph 11, the following
capitalized words shall have the meanings set forth below:

         "Cause" shall mean a termination of the Employee's employment by the
Employer which is a result of (i) his felony conviction, (ii) his willful
disclosure of material trade secrets or other material confidential information
related to the business of the Employer and its subsidiaries or (iii) his
willful and continued failure substantially to perform his duties with the
Employer (other than any such failure resulting from his incapacity due to
physical or mental illness or any such actual or anticipated failure resulting
from a resignation by the Employee for Good Reason) after a written demand for
substantial performance is delivered to the Employee by the Board, which demand
specifically identifies the manner in which the Board believes that the Employee
has not substantially performed his duties, and which performance is not
substantially corrected by him within 10 days of receipt of such demand. For
purposes of the previous sentence, no act or failure to act on the Employee's
part shall be deemed "willful" unless done, or omitted to be done, by him not in
good faith and without reasonable belief that his action or omission was in the
best interest of the Employer. Notwithstanding the foregoing, the Employee shall
not be deemed to have been terminated for Cause unless and until there shall
have been delivered to him a copy of a resolution duly adopted by the
affirmative vote of not less than three-fourths (3/4ths) of the entire
membership of the Board at a meeting of the Board called and held for such
purpose (after reasonable notice to the Employee and an opportunity for him,
together with his counsel, to be heard before the Board), finding that in the
good faith opinion of the Board he was guilty of conduct set forth above in
clause (i), (ii) or (iii) of the first sentence of this definition and
specifying the particulars thereof in detail.

         "Change in Control" shall mean the happening of any of the following:

         (i) any person or entity, including a "group" as defined in Section
     13(d)(3) of the Exchange Act, other than the Employer, a subsidiary of the
     Employer, or any employee benefit plan of the Employer or its subsidiaries,
     becomes the beneficial owner of the Employer's securities having 25 percent
     or more of the combined voting power of the then outstanding securities of
     the Employer that may be cast for the election for directors of the
     Employer (other than as a result of an issuance of securities initiated by
     the Employer in the ordinary course of business); or

<PAGE>   10


         (ii) as the result of, or in connection with, any cash tender or
     exchange offer, merger or other business combination, sale of assets or
     contested election, or any combination of the foregoing transactions, less
     than a majority of the combined voting power of the then outstanding
     securities of the Employer or any successor corporation or entity entitled
     to vote generally in the election of directors of the Employer or such
     other corporation or entity after such transaction, are held in the
     aggregate by holders of the Employer's securities entitled to vote
     generally in the election of directors of the Employer immediately prior to
     such transactions; or

         (iii) during any period of two consecutive years, individuals who at
     the beginning of any such period constitute the Board cease for any reason
     to constitute at least a majority thereof, unless the election, or the
     nomination for election by the Employer's stockholders, of each director of
     the Employer first elected during such period was approved by a vote of at
     least two-thirds of the directors of the Employer then still in office who
     were directors of the Employer at the beginning of any such period
     (together, directors at the beginning of such period and new directors
     whose election or nomination was so approved are the "Incumbent
     Directors").

         "Change in Control Date" shall mean the date on which the Change in
Control occurs. Notwithstanding the first sentence of this section, if the
Employee's employment with the Employer terminates prior to the Change in
Control Date and it is reasonably demonstrated that his termination of
employment (i) was at the request of the third party who has taken steps
reasonably calculated to effect the Change in Control or (ii) otherwise arose in
connection with or in anticipation of the Change in Control, then Change in
Control Date shall mean the date immediately prior to the date of the Employee's
termination of employment.

         "Common Stock" shall mean the common stock of the Employer.

         "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended, and any successor provisions thereto.

         "Good Reason" shall mean a resignation by the Employee from his
employment with the Employer on or following the Change in Control Date as a
result of the occurrence of any of the following without his consent:

         (i) A failure by the Employer to ensure that the Employee's position,
     titles, nature and status of responsibilities and reporting obligations are
     substantially equivalent to those that the Employee enjoyed immediately
     prior to the Change in Control Date, it being understood and agreed that
     such features shall not be deemed less than substantially equivalent solely
     by reason of the Employer ceasing to be a public company.

         (ii) A reduction by the Employer in the Employee's annual base salary
     as in effect immediately prior to the Change in Control Date or as the same
     may be increased from time to time thereafter; a failure by the Employer to
     increase the Employee's salary at a rate commensurate with that of other
     key executives of the Employer; or a reduction in the 

<PAGE>   11


    Employee's target annual bonus (expressed as a percentage of base salary)
    below the target in effect for him prior to the Change in Control Date;

         (iii) The relocation of the office of the Employer where the Employee
     is employed immediately prior to the Change in Control Date (the "CIC
     Location") to a location which is more than fifty (50) miles away from the
     CIC Location or the Employer's requiring the Employee to be based more than
     fifty (50) miles away from the CIC Location (except for required travel on
     the Employer's business to an extent substantially consistent with his
     customary business travel obligations in the ordinary course of business
     prior to the Change in Control Date), unless such relocation is to a
     location closer to his principal residence;

         (iv) The failure by the Employer to continue in effect any compensation
     plan in which the Employee participated prior to the Change in Control Date
     or made available to him after the Change in Control Date, unless an
     equitable arrangement ' (embodied in an ongoing substitute or alternative
     plan) has been made with respect to such plan in connection with the Change
     in Control, or the failure by the Employer to continue the Employee's
     participation therein on at least as favorable a basis, both in terms of
     the amount of benefits provided and the level of his participation relative
     to other participants, as existed on the Change in Control Date;

         (v) The failure by the Employer to continue to provide the Employee
     with benefits at least as favorable in the aggregate to those enjoyed by
     him under the Employer's pension, savings, life insurance, medical, health
     and accident, disability, and fringe benefit plans and programs in which he
     was participating immediately prior to the Change in Control Date, or the
     failure by the Employer to provide the Employee with the number of paid
     vacation days to which he is entitled on the basis of years of service with
     the Employer in accordance with the Employer's normal vacation policy in
     effect immediately prior to the Change in Control;

         (vi) The failure of the Employer to obtain an agreement reasonably
     satisfactory to the Employee from any successor to assume and agree to

     principally performed is sold at any time after a Change in Control, the
     failure of the Employer to obtain such an agreement from the purchaser of
     such business;

         (vii) Any termination of the Employee's employment which is not
     effected pursuant to the terms of this Agreement; or

         (viii) A material breach by the Employer of the provisions of this
     Agreement;

provided, however, that an event described above in clause (i), (ii), (iv), (v)
or (viii) shall not constitute Good Reason unless it is communicated by the
Employee to the Employer in writing and is not corrected by the Employer in a
manner which is reasonably satisfactory to the Employee (including full
retroactive correction with respect to any monetary matter) within 10 days of
the Employer's receipt of such written notice from him.


<PAGE>   12

         "Involuntary Termination" shall mean (i) the termination of the
Employee's employment during the Covered Period by the Employer and its
subsidiaries other than for Cause or disability or (ii) the Employee's
resignation of employment during the Covered Period with the Employer and its
subsidiaries for Good Reason.

         12. Successors; Binding Agreement.

         (a) Assumption by Successor. The Employer will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Employer expressly to
assume and to agree to perform this Agreement in the same manner and to the same
extent that the Employer would be required to perform it if no such succession
had taken place-, provided, however, that no such assumption shall relieve the
Employer of its obligations hereunder. As used in this Agreement, the "Employer"
shall mean the Employer as hereinbefore defined and any successor to its
business and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law or otherwise.

         (b) Enforceability: Beneficiaries. This Agreement shall be binding upon
and inure to the benefit of the Employee (and his personal representatives and
heirs) and the Employer and any organization which succeeds to substantially all
of the business or assets of the Employer, whether by means of merger,
consolidation, acquisition of all or substantially all of the assets of the
Employer or otherwise, including, without limitation, as a result of a Change in
Control or by operation of law. This Agreement shall inure to the benefit of and
be enforceable by the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Employee should die while any amount would still be payable to him hereunder if
he had continued to live, all such amounts, unless otherwise provided herein,
shall be paid in accordance with the terms of this Agreement to his devisee,
legatee or other designee or, if there is no such designee, to his estate.

         13. Notices. Any notice required or permitted to be given under this
Agreement shall be sufficient if in writing and delivered personally or sent by
registered mail (i) to Employee's residence, in the case of the Employee, or
(ii) to the business address of its President and Chief Executive Officer, in
the case of the Employer.

         14. Waiver of Breach and Severability. The waiver by the Employer of a
breach of any provision of this Agreement by the Employee shall not operate or
be construed as a waiver of any subsequent breach by the Employee. In the event
any provision of this Agreement is found to be invalid or unenforceable, it may
be severed from the Agreement and the remaining provision of the Agreement shall
continue to be binding and effective; provided, however, that, if possible, it
is the intention of the Employer and the Employee that such provision be
construed and interpreted as narrowly as necessary in order to make such
provision valid and enforceable.

         15. Entire Agreement. This instrument and the letter agreement between
the Employee and the Employer dated January 1, 1996 contain the entire agreement
of the parties and supersede any prior understandings and agreements between
them respecting the subject



<PAGE>   13

matter of this Agreement, including, without limitation, the Employment
Agreement dated as of January 1, 1996. It may not be changed orally, but only by
an agreement in writing signed by the party against whom enforcement of any
waiver, change, modification; extension or discharge is sought.

         16. Survival. Upon termination of the Employee's employment with the
Company prior to a Change in Control Date, the rights and obligations of the
parties hereto as provided in paragraphs 8 and 9 shall continue for the time
periods as set forth herein.

         17. Governing Law. This Agreement shall be construed in accordance with
and governed by the laws of the State of Tennessee without regard to the laws of
any other state or jurisdiction. Any action brought or maintained in connection
with this Agreement shall be brought exclusively in the courts located in Shelby
County, Tennessee. Each of the Employer and the Employee hereby irrevocably
waives all right to trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement.

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         AMENDED AND RESTATED EMPLOYMENT AGREEMENT, dated as of the 27th day of
April, 1997, between SOFAMOR DANEK GROUP, INC., an Indiana corporation (the
"Employer"), and Ed Traurig (the "Employee").

                                    RECITALS

         WHEREAS, the Employer is an Indiana corporation and through its wholly
owned subsidiaries, Warsaw Orthopedic, Inc., Danek Medical, Inc., and Sofamor,
S.N.C. is engaged in the business of developing, manufacturing and distributing
medical devices, trauma instruments, surgical tools and implants (such business,
as it may change from time to time, is hereinafter referred to as "Business");
and

         WHEREAS, the Board of Directors of the Employer (the "Board") has
concluded that it desires to retain the valued services of the Employee by
entering into a new agreement which shall provide the Employee with certain
additional protections which are designed to ensure that the Employee will
devote himself attentively and energetically to his duties without distraction;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants contained herein, the parties agree as follows:

         1. Employment. The Employer (or a subsidiary of the Employer) hereby 
employs the Employee and the Employee hereby accepts employment upon the terms
and conditions hereinafter set forth.

         2. Term. Subject to the provisions for termination as provided in
paragraph 10 hereof, the term of this Agreement shall be from April 29, 1997 to
December 31, 1999, and it shall be automatically renewed for successive one (1)
year periods thereafter, unless either party elects not to renew this Agreement
by serving notice of such intention not to renew on the other party at least
ninety (90) days prior to the renewal date. Notwithstanding the foregoing, if a
Change in Control Date (as defined in paragraph 11) occurs during the term
described in the immediately preceding sentence, the term of the Employee's
employment hereunder shall extend until the third anniversary of such Change in
Control Date (the period beginning on such Change in Control Date and ending on
the third anniversary thereof being hereinafter referred to as the "Covered
Period").

         3. Duties. The Employee is engaged as Vice President, U.S. Sales of the
Employer to assist the President and CEO of the Employer in managing, directing
and administering all aspects and matters of the Business, subject to the
direction and guidance of the President and CEO of the Employer. Prior to a
Change in Control (as hereinafter defined), the precise services, duties and
authority of the Employee as Vice President, U.S. Sales of the Employer may be


<PAGE>   3

further defined, extended or curtailed from time to time at the discretion of
the President and CEO of the Employer.

         4. Extent of Services. The Employee shall have the power and authority
commensurate and necessary to his position of Vice President, U.S. Sales and his
other duties as assigned to him from time to time. He shall devote his entire
employable time, attention and best efforts to the Business as may be necessary
to efficiently and effectively perform and complete the duties he is to
undertake as described in this Agreement. The Employee shall not, without the
consent of the Employer, which consent shall not be unreasonably withheld,
during the term of this Agreement, be actively engaged in any other business
activity, whether or not such business activity is pursued for gain, profit and
other pecuniary advantage; but this shall not be construed as preventing the
Employee from investing his personal assets in such form or manner as will not
require any services on the part of the Employee in the operation of the affairs
of the companies in which such investments are made.

         5. Compensation. The Employee shall be compensated for services
rendered hereunder as follows:

         (a) The Employee shall receive a salary of not less than $16,467 per
month for each month of the first twelve (12) months that this Agreement is in
effect and for each month thereafter so long as the Employee receives Job
Performance Evaluations of "good" or better. After such first year, if the
Employee receives a Job Performance Evaluation of less than "good", his salary
shall be determined in the discretion of the President and CEO of the Employer.
Such salary paid to the Employee shall be subject to withholding of taxes and
other appropriate and customary amounts.

         (b) The Employee shall be entitled to participate in the employee
benefit plans the Employer may adopt from time to time for its management or
supervisory personnel generally at such time as the Employee shall have
fulfilled the eligibility requirements for participation therein as shall be
determined by the terms of the applicable contracts for each program. Nothing
herein shall be construed so as to prevent the Employer from modifying or
terminating any employee benefit plans or programs or employee fringe benefits
it currently sponsors or may adopt from time to time.

         6. Expenses and Travel. It is expected that in the course of his
employment, the Employee and his spouse shall be required to spend time
traveling and entertaining various persons on behalf of the Employer and
promoting the affairs of the Employer. The Employer shall provide to the
Employee an Employer Mastercard credit card or the Employer shall pay the
Employee the annual fee for one (1) personal credit card. The Employer shall pay
for or reimburse the Employee for all such reasonable expenses upon the
Employee's periodic presentation of an itemized account of such expenditures,
provided, however, the Employer shall only pay for or reimburse for the cost of
coach class air fare for business travel within the United States and only for
the cost of business class air fare for international business air travel. The
Employer shall bear the expense, in an amount not to exceed $250 per month, for
country club or social club dues for which the Employee may become a member
during the term hereof and/or a

<PAGE>   4

portable telephone and related telephone service, the use of either of which is
related to the Business. The Employee shall bear the expense of any initiation
fees and other assessments for or resulting from such membership. The Employee
shall be reimbursed in an amount not to exceed a total of $2,000 for each year
during the term or any renewal term hereof, for expenses incurred for his spouse
when traveling with the Employee on business matters for the Employer.

         7. Disability. If the Employee shall become physically or mentally
disabled during the term of this Agreement to the extent that he shall be unable
to perform his duties and services for and on behalf of the Employer, the
benefits made available to the Employee and the salary then payable to the
Employee pursuant to the foregoing paragraph 5 shall continue to be made
available and paid to the Employee for the shorter of (i) the period of
disability; or (ii) six (6) months from the commencement of the disability.
Thereafter, the Employee shall receive no salary from the Employer.

         8. Confidentiality. The Employee possesses and will continue to possess
information which has been created, discovered, developed by or otherwise become
known to the Employee (including information discovered or made available by
subsidiaries, affiliates or joint ventures of the Employer or in which property
rights have been assigned or otherwise conveyed to the Employer), which
information has commercial value to the Employer, including but not limited to
trade secrets, innovations, processes, computer codes, data, know-how,
improvements, discoveries, developments, techniques, marketing plans,
strategies, costs, customer and client lists, or any information the Employee
has reason to know the Employer would treat as confidential for any purpose,
whether or not developed by the Employee (hereinafter referred to as
"Confidential Information"). Unless previously authorized in writing or
instructed in writing by the Employer, the Employee will not, at any time,
disclose to others, or use, or allow anyone else to disclose or use any
Confidential Information (except as may be necessary in the performance of the
Employee's employment with the Employer), unless, until and then only to the
extent that such Confidential Information has become ascertainable or obtained
from public or published sources or was available to the Employee on a
non-confidential basis prior to any such disclosure or use, provided that the
source of such material is or was not bound by an obligation of confidentiality
to the Employer. This paragraph 8 shall survive termination of this Agreement.

         9. Restrictive Covenants. The terms of this paragraph 9 shall be
applicable during the Employee's employment and upon the termination of such
employment for any reason occurring prior to a Change in Control Date. In the
event of termination "without cause" as defined in paragraph 10(b) occurring
prior to a Change in Control Date, in consideration of, and subject to, the
Employee's continued compliance with the terms of this paragraph 9, the Employer
shall pay to the Employee twelve (12) months salary based on his salary for the
month immediately preceding the date of termination which shall be paid in
accordance with the Employer's customary payroll practices over twelve (12)
months. In the event of a termination for any other reason, including for "just
cause" as defined in paragraph 10(b) occurring prior to a Change in Control
Date, the Employer shall have no obligation to the Employee. This paragraph 9
shall survive termination of this Agreement occurring prior to a Change in
Control Date.

         The Employee acknowledges that because of his skills, the Employee's
position with the Employer and the Confidential Information to which the
Employee shall have access or be provided on account of such employment with the
Employer, competition by the Employee with the Employer could damage the
Employer in a manner which cannot adequately be compensated by damages or an
action at law, In view of such circumstances, because of the Confidential
Information obtained by, or disclosed to the Employee, and as a material
inducement to the Employer to enter into this Agreement and to compensate the
Employee, as described in paragraph 5, as well as provide him with additional
benefits as provided herein and other good and valuable consideration, the
Employee covenants and agrees that:

         (a) Noncompetition. During the Employee's employment with the Employer
and for a period of three (3) years thereafter, the Employee shall not (as
principal, agent, employee, consultant or otherwise), directly or indirectly, in
any geographic area in which the Employer is engaged in Business, engage in
activities for, or render services of any nature to, any firm or business, which
firm or business competes, directly or indirectly, with the Employer or the
Business.

         (b) Nonsolicitation of Customers. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit, divert or accept any work or services
which compete with the Employer's Business from any customer of the Employer or
seek to cause any such customer to refrain from doing business with or
patronizing the Employer.

         (c) Nonsolicitation of Employees. During the Employee's employment with
the Employer and for a period of three (3) years thereafter, the Employee shall
not, directly or indirectly, solicit for employment or employ any current or
former employee of the Employer.

         (d) Definitions. For purposes of this Agreement, the term "directly or
indirectly" shall be construed in its broadest sense and shall include the
activities of the members of the Employee's immediate family or any partnership.
The term "Business" shall be construed in its broadest sense and shall include
any activity engaged in or conducted by the Employer or any of its subsidiaries,
affiliates or joint ventures or which the Employer or any of its subsidiaries,
affiliates or joint ventures intends to engage in or conduct. The term
"customer" shall mean any person or entity with which the Employer, or any of
its subsidiaries, affiliates or joint ventures has engaged in or conducted
Business during the one (1) year period prior to the date the Employee ceased
employment with the Employer or any persons or entities targeted by the Employer
or contacted for the purpose of engaging in or conducting Business during such
one (1) year period.

         (e) Reasonable Limitations. Given the important nature of the position
the Employee will hold with the Employer, the nature of the Employer's Business
and the sensitive nature of the Confidential Information and duties the Employee
will have with the Employer, the parties acknowledge that the limitations,
including but not limited to, the scope of activities prohibited, the geographic
area covered and the time limitation, are reasonable.

         In the event of an actual or threatened breach by the Employee of the
provisions of paragraphs 8 and 9 of this Agreement, the Employer shall be
entitled to a temporary restraining order and an injunction restraining the
Employee from such breach. Nothing herein, however, shall be construed as
prohibiting the Employer from pursuing any other remedies available to it for
such actual or threatened breach, including, without limitation, the recovery of
damages and reasonable attorneys' and paralegals' fees and costs from the
Employee. If the Employee violates any of the covenants in paragraphs 8 and 9 of
this Agreement, the term and the covenant violated shall be automatically
extended for the period of time of the violation, either from the date on which
the Employee ceases such violation or from the date of the entry by a court of
competent jurisdiction of an order or judgment enforcing such covenants,
whichever period is later.

         10. Termination Prior to a Change in Control Date. The Employer may, at
its option, terminate this Agreement at any time prior to the occurrence of a
Change in Control Date upon written notice to the Employee for just cause or
without cause.

         (a)      "Just cause" shall include, but not be limited to:

                  (i)     The Employee receiving a Job Performance Evaluation of
                          less than "good";

                  (ii)    The Employee's misuse or embezzlement of funds
                          belonging to the Employer, conviction of a felony or
                          crime involving moral turpitude or use of alcohol or
                          drugs in such a manner as will injure or adversely
                          affect the reputation of the Employer or its
                          employees, customers, agents, officers or directors;

                  (iii)   The Employee's absence from his employment, for
                          whatever cause, other than by disability for which
                          salary is continued pursuant to paragraph 7, for a
                          period of thirty (30) consecutive days or more;

                  (iv)    The Employee's absence from employment as a result of
                          disability beyond the period for which salary is
                          continued pursuant to paragraph 7;

                  (v)     The Employee's resignation from employment during the
                          term hereof or if the Employee serves notice to not
                          renew this Agreement as provided in paragraph 2;

                  (vi)    The Employee's willful malfeasance in discharging his
                          obligations hereunder and such acts and their
                          consequences are not remedied within ten (10) days or
                          such longer reasonable period of time designated by
                          the Employer after written notice thereof has been
                          given to the Employee; or

                  (vii)   The Employee's breach of the provisions of this
                          Agreement and such breach and its consequences are not

                          reasonable period of time designated by the Employer,
                          after written notice thereof has been given to the
                          Employee.


<PAGE>   7

         (b)      "Without cause" shall mean:

                  (i)     The termination and dissolution of the Employer or a
                          bona fide decision by the Employer
                          to terminate its Business; or

                  (ii)    Any involuntary termination of the Employee's
                          employment by the Employer without just cause.

         (c) In addition to those reasons enumerated above, this Agreement shall
be terminated upon the happening of any of the following events:

                  (i)     Whenever the Employer and the Employee shall mutually 
                          agree to a termination in writing; or

                  (ii)    Upon death of the Employee.

Upon the termination of this Agreement prior to the occurrence of a Change in
Control Date for any of the foregoing reasons in paragraph 10, the Employee
shall be entitled to receive only the compensation accrued but unpaid as of the
date of the termination hereof and shall not be entitled to additional
compensation except as expressly provided in paragraph 9 of this Agreement.

         11. Effect of a Change in Control.

         (a) Involuntary Termination; Consulting Period.

         (i) Consulting Services Following an Involuntary Termination. In the
event of the Employee's Involuntary Termination during the Covered Period he
shall commence providing consulting services to the Employer for a period (the
"Consulting Period") of (i) three years, in the event the Involuntary
Termination occurs during the first year of the Covered Period, (ii) two years,
in the event the Involuntary Termination occurs during the second year of the
Covered Period, or (iii) one year, in the event the Involuntary Termination
occurs in the last year of the Covered Period. The Employee's consulting
services shall consist in advising the Employer on such matters as may be
reasonably requested by the Employer. Such services shall be performed at such
times and in such locations as shall be mutually agreed by the Employee and the
Employer, and shall not interfere with his duties to a new employer. In any
event, the Employee shall not be required to perform consulting services for
more than 8 hours per month during the Consulting Period. The Employee shall not
be an employee of the Employer during the Consulting Period, but shall act
solely in the capacity of an independent contractor.

         (ii) Consulting Fees: Reimbursement of Expenses. In consideration of
the Employee's agreement to provide consulting services hereunder, the Employer
shall pay the Employee, not less than 5 days following an Involuntary
Termination, a lump sum consulting fee payment equal to the product of (A) the
Employee's base salary in effect immediately prior to his Date of Termination
(without taking into account any salary reduction that gave rise to Good
Reason), and (B) the number of years in the Consulting Period, as determined
pursuant to

<PAGE>   8

paragraph 11(a)(i) above. In addition, the Employee shall be reimbursed for all
expenses reasonably incurred by him in connection with the performance of his
consulting services hereunder. The Employee shall not be entitled to benefits
under any other severance pay plan or arrangement sponsored by the Employer and
its subsidiaries in the event of an Involuntary Termination during the Covered
Period, and any amounts payable to him under any statutory severance policy
shall reduce the aggregate amount of the consulting fees payable hereunder. In
addition, in the event of the Employee's Involuntary Termination, the Employer
shall pay him within 5 days of the date of such Involuntary Termination the full
amount of any earned but unpaid base salary through the Date of Termination at
the rate in effect at the time of the Notice of Termination, plus a cash payment
for all unused vacation time which he may have accrued as of the Date of
Termination. The Employer shall also pay the Employee within 5 days of the Date
of Termination a pro rata portion of his projected annual bonus for the year in
which his Involuntary Termination occurs, calculated on the basis of his target
bonus for that year.

         (iii) Benefits. The Employee and his eligible dependents shall continue
to be eligible to participate during the Consulting Period in the medical,
dental, health, life and other fringe benefit plans and arrangements applicable
to him immediately prior to his Involuntary Termination on the same terms and
conditions in effect for the Employee and his dependents immediately prior to
such Involuntary Termination; provided, however, that any benefit plan or
arrangement will end on the date that the Employee and his dependents are
eligible and elect coverage under a plan or arrangement of a subsequent employer
which provides a substantially equivalent or greater benefit to him and his
dependents.

         (iv) Date and Notice of Termination. Any termination of the Employee's
employment during the Covered Period by the Employer or by the Employee shall be
communicated by a notice of termination to the other party hereto (the "Notice
of Termination"). The Notice of Termination shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Employee's employment under the provision so indicated. The
date of the Employee's termination of employment with the Employer and its
subsidiaries (the "Date of Termination") shall be determined as follows- (i) if
the Employee's employment is terminated by the Employer in an Involuntary
Termination, five (5) days after the date the Notice of Termination is received
by the Employee and (ii) if the Employee's employment is terminated by the
Employer for just cause, the date specified in the Notice of Termination. If the
basis for the Employee's Involuntary Termination is his resignation for Good
Reason, the Date of Termination shall be ten (10) days after the date his Notice
of Termination is received by the Employer. The Date of Termination for a
resignation of employment other than for Good Reason shall be the date set forth
in the applicable notice, which shall be no earlier than ten (10) days after the
date such notice is received by the Employer.

         (b) Non-Competition Agreement. During the Consulting Period, the
Employee shall comply with the substantive restrictions set forth in paragraphs
8 and 9 above.

         (c) Legal Fees and Expenses. The Employer shall pay or reimburse the
Employee on an after-tax basis for all costs and expenses (including, without
limitation, court costs and 



<PAGE>   9

reasonable legal fees and expenses which reflect common practice with respect to
the matters involved) incurred by him as a result of any claim, action or
proceeding (i) arising out of his termination of employment during the Covered
Period, (ii) contesting, disputing or enforcing any right, benefits or
obligations under this paragraph I 1 or (iii) arising out of or challenging the
validity, advisability or enforceability of this paragraph I 1 or any provision
thereof; provided, however, that this provision will not apply if the trier of
fact determines that the Employee's claim was entirely without merit.

         (d) Definitions. For purposes of this paragraph 11, the following
capitalized words shall have the meanings set forth below:

         "Cause" shall mean a termination of the Employee's employment by the
Employer which is a result of (i) his felony conviction, (ii) his willful
disclosure of material trade secrets or other material confidential information
related to the business of the Employer and its subsidiaries or (iii) his
willful and continued failure substantially to perform his duties with the
Employer (other than any such failure resulting from his incapacity due to
physical or mental illness or any such actual or anticipated failure resulting
from a resignation by the Employee for Good Reason) after a written demand for
substantial performance is delivered to the Employee by the Board, which demand
specifically identifies the manner in which the Board believes that the Employee
has not substantially performed his duties, and which performance is not
substantially corrected by him within 10 days of receipt of such demand. For
purposes of the previous sentence, no act or failure to act on the Employee's
part shall be deemed "willful" unless done, or omitted to be done, by him not in
good faith and without reasonable belief that his action or omission was in the
best interest of the Employer. Notwithstanding the foregoing, the Employee shall
not be deemed to have been terminated for Cause unless and until there shall
have been delivered to him a copy of a resolution duly adopted by the
affirmative vote of not less than three-fourths (3/4ths) of the entire
membership of the Board at a meeting of the Board called and held for such
purpose (after reasonable notice to the Employee and an opportunity for him,
together with his counsel, to be heard before the Board), finding that in the
good faith opinion of the Board he was guilty of conduct set forth above in
clause (i), (ii) or (iii) of the first sentence of this definition and
specifying the particulars thereof in detail.

         "Change in Control" shall mean the happening of any of the following:

                  (i) any person or entity, including a "group" as defined in
         Section 13(d)(3) of the Exchange Act, other than the Employer, a
         subsidiary of the Employer, or any employee benefit plan of the
         Employer or its subsidiaries, becomes the beneficial owner of the
         Employer's securities having 25 percent or more of the combined voting
         power of the then outstanding securities of the Employer that may be
         cast for the election for directors of the Employer (other than as a
         result of an issuance of securities initiated by the Employer in the
         ordinary course of business); or

                  (ii) as the result of, or in connection with, any cash tender
         or exchange offer, merger or other business combination, sale of assets
         or contested election, or any combination of the foregoing
         transactions, less than a majority of the combined voting 

<PAGE>   10

         power of the then outstanding securities of the Employer or any
         successor corporation or entity entitled to vote generally in the
         election of directors of the Employer or such other corporation or
         entity after such transaction, are held in the aggregate by holders of
         the Employer's securities entitled to vote generally in the election
         of directors of the Employer immediately prior to such transactions;
         or

                  (iii) during any period of two consecutive years, individuals
         who at the beginning of any such period constitute the Board cease for
         any reason to constitute at least a majority thereof, unless the
         election, or the nomination for election by the Employer's
         stockholders, of each director of the Employer first elected during
         such period was approved by a vote of at least two-thirds of the
         directors of the Employer then still in office who were directors of
         the Employer at the beginning of any such period (together, directors
         at the beginning of such period and new directors whose election or
         nomination was so approved are the "Incumbent Directors").

         "Change in Control Date" shall mean the date on which the Change in
Control occurs. Notwithstanding the first sentence of this section, if the
Employee's employment with the Employer terminates prior to the Change in
Control Date and it is reasonably demonstrated that his termination of
employment (i) was at the request of the third party who has taken steps
reasonably calculated to effect the Change in Control or (ii) otherwise arose in
connection with or in anticipation of the Change in Control, then Change in
Control Date shall mean the date immediately prior to the date of the Employee's
termination of employment.

         "Common Stock" shall mean the common stock of the Employer.

         "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended, and any successor provisions thereto.

         "Good Reason" shall mean a resignation by the Employee from his
employment with the Employer on or following the Change in Control Date as a
result of the occurrence of any of the following without his consent:

                  (i) A failure by the Employer to ensure that the Employee's
         position, titles, nature and status of responsibilities and reporting
         obligations are substantially equivalent to those that the Employee
         enjoyed immediately prior to the Change in Control Date, it being
         understood and agreed that such features shall not be deemed less than
         substantially equivalent solely by reason of the Employer ceasing to be
         a public company.

                  (ii) A reduction by the Employer in the Employee's annual base
         salary as in effect immediately prior to the Change in Control Date or
         as the same may be increased from time to time thereafter; a failure by
         the Employer to increase the Employee's salary at a rate commensurate
         with that of other key executives of the Employer; or a reduction in
         the Employee's target annual bonus (expressed as a percentage of base
         salary) below the target in effect for him prior to the Change in
         Control Date;

<PAGE>   11

                  (iii) The relocation of the office of the Employer where the
         Employee is employed immediately prior to the Change in Control Date
         (the "CIC Location") to a location which is more than fifty (50) miles
         away from the CIC Location or the Employer's requiring the Employee to
         be based more than fifty (50) miles away from the CIC Location (except
         for required travel on the Employer's business to an extent
         substantially consistent with his customary business travel obligations
         in the ordinary course of business prior to the Change in Control
         Date), unless such relocation is to a location closer to his principal
         residence;

                  (iv) The failure by the Employer to continue in effect any
         compensation plan in which the Employee participated prior to the
         Change in Control Date or made available to him after the Change in
         Control Date, unless an equitable arrangement ' (embodied in an ongoing
         substitute or alternative plan) has been made with respect to such plan
         in connection with the Change in Control, or the failure by the
         Employer to continue the Employee's participation therein on at least
         as favorable a basis, both in terms of the amount of benefits provided
         and the level of his participation relative to other participants, as
         existed on the Change in Control Date;

                  (v) The failure by the Employer to continue to provide the
         Employee with benefits at least as favorable in the aggregate to those
         enjoyed by him under the Employer's pension, savings, life insurance,
         medical, health and accident, disability, and fringe benefit plans and
         programs in which he was participating immediately prior to the Change
         in Control Date; or the failure by the Employer to provide the Employee
         with the number of paid vacation days to which he is entitled on the
         basis of years of service with the Employer in accordance with the
         Employer's normal vacation policy in effect immediately prior to the
         Change in Control;

                  (vi) The failure of the Employer to obtain an agreement
         reasonably satisfactory to the Employee from any successor to assume
         and agree to perform this Agreement, as contemplated in paragraph 12(a)
         hereof or, if the business of the Employer for which the Employee's
         services are principally performed is sold at any time after a Change
         in Control, the failure of the Employer to obtain such an agreement
         from the purchaser of such business;

                  (vii) Any termination of the Employee's employment which is
         not effected pursuant to the terms of this Agreement; or

                  (viii) A material breach by the Employer of the provisions of
         this Agreement;

provided, however, that an event described above in clause (i), (ii), (iv), (v)
or (viii) shall not constitute Good Reason unless it is communicated by the
Employee to the Employer in writing and is not corrected by the Employer in a
manner which is reasonably satisfactory to the Employee (including full
retroactive correction with respect to any monetary matter) within 10 days of
the Employer's receipt of such written notice from him.


<PAGE>   12

         "Involuntary Termination" shall mean (i) the termination of the
Employee's employment during the Covered Period by the Employer and its
subsidiaries other than for Cause or disability or (ii) the Employee's
resignation of employment during the Covered Period with the Employer and its
subsidiaries for Good Reason.

         12. Successors, Binding Agreement.

         (a) Assumption by Successor. The Employer will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Employer expressly to
assume and to agree to perform this Agreement in the same manner and to the same
extent that the Employer would be required to perform it if no such succession
had taken place; provided, however, that no such assumption shall relieve the
Employer of its obligations hereunder. As used in this Agreement, the "Employer"
shall mean the Employer as hereinbefore defined and any successor to its
business and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law or otherwise.

         (b) Enforceability; Beneficiaries. This Agreement shall be binding upon
and inure to the benefit of the Employee (and his personal representatives and
heirs) and the Employer and any organization which succeeds to substantially all
of the business or assets of the Employer, whether by means of merger,
consolidation, acquisition of all or substantially all of the assets of the
Employer or otherwise, including, without limitation, as a result of a Change in
Control or by operation of law. This Agreement shall inure to the benefit of and
be enforceable by the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Employee should die while any amount would still be payable to him hereunder if
he had continued to live, all such amounts, unless otherwise provided herein,
shall be paid in accordance with the terms of this Agreement to his devisee,
legatee or other designee or, if there is no such designee, to his estate.

         13. Notices. Any notice required or permitted to be given under this
Agreement shall be sufficient if in writing and delivered personally or sent by
registered mail (i) to Employee's residence, in the case of the Employee, or
(ii) to the business address of its President and Chief Executive Officer, in
the case of the Employer.

         14. Waiver of Breach and Severability. The waiver by the Employer of a
breach of any provision of this Agreement by the Employee shall not operate or
be construed as a waiver of any subsequent breach by the Employee. In the event
any provision of this Agreement is found to be invalid or unenforceable, it may
be severed from the Agreement and the remaining provision of the Agreement shall
continue to be binding and effective; provided, however, that, if possible, it
is the intention of the Employer and the Employee that such provision be
construed and interpreted as narrowly as necessary in order to make such
provision valid and enforceable.

         15. Entire Agreement. This instrument and the letter agreement between
the Employee and the Employer dated January 1, 1996 contain the entire agreement
of the parties 

<PAGE>   13

and supersede any prior understandings and agreements between them respecting
the subject matter of this Agreement, including, without limitation, the
Employment Agreement dated as of January 1, 1996. It may not be changed orally,
but only by an agreement in writing signed by the party against whom enforcement
of any waiver, change, modification; extension or discharge is sought.

         16. Survival. Upon termination of the Employee's employment with the
Company prior to a Change in Control Date, the rights and obligations of the
parties hereto as provided in paragraphs 8 and 9 shall continue for the time
periods as set forth herein.

         17. Governing Law. This Agreement shall be construed in accordance with
and governed by the laws of the State of Tennessee without regard to the laws of
any other state or jurisdiction. Any action brought or maintained in connection
with this Agreement shall be brought exclusively in the courts located in Shelby
County, Tennessee. Each of the Employer and the Employee hereby irrevocably
waives all right to trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement.



<PAGE>   14


         IN WITNESS WHEREOF, the parties hereto execute this Agreement on the
date first above written.

increased by the Compensation Committee at that committee's annual review. This

changes for the following year.

                    1993 LONG-TERM INCENTIVE PLAN, AS AMENDED

1. PURPOSE.

The purpose of the SOFAMOR DANEK GROUP, INC. 1993 LONG-TERM INCENTIVE PLAN, AS
AMENDED (the "Plan") is to further the earnings of SOFAMOR DANEK GROUP, INC., an
Indiana corporation, and its subsidiaries (collectively, the "Company") by
assisting the Company in attracting, retaining and motivating management
employees and directors of high caliber and potential. The Plan provides for the
award of long-term incentives to those officers, other key executives and
directors who make substantial contributions to the Company by their loyalty,
industry and invention. In addition, the Plan contains a program (the "Director
Program") which provides for the non-discretionary periodic grant of
Non-Qualified Stock Options (as hereinafter defined) to non-employee directors
of the Company (the "Director Options").

2. ADMINISTRATION.

The Plan (other than the Director Program) shall be administered by a committee
(the "Committee"). The Board of Directors of the Company (the "Board of
Directors") may act as the Committee, or it may delegate such responsibility to
one or more of its members. The Committee shall have full and final authority in
its discretion to interpret the provisions of the Plan (other than the Director
Program) and to decide all questions of fact arising in its application. Subject
to the provisions hereof and other than with respect to the Director Program,
the Committee shall have full and final authority in its discretion to determine
the employees and directors to whom awards shall be made under the Plan; to
determine the type of awards to be made under the Plan and the amount, size and
terms and conditions of each such award under the Plan; to determine the time
when awards shall be granted; to determine the provisions of each agreement
evidencing an award; and to make all other determinations necessary or advisable
for the administration of the Plan.

3. STOCK SUBJECT TO THE PLAN.

The Company may grant awards under the Plan with respect to not more than a
total of 7,500,000 shares of no par value common stock of the Company (the
"Shares") (subject, however, to adjustment as provided in paragraph 21 below).
Such Shares may be authorized and un-issued Shares or treasury Shares. In any
calendar year, no participant may be granted awards relating to more than
500,000 shares. Except as otherwise provided herein, any Shares subject to an
option or right which for any reason is surrendered before exercise or expires
or is terminated unexercised as to such Shares shall again be available for the
granting of awards under the Plan. Similarly, if any Shares granted pursuant to
restricted stock awards are forfeited, such forfeited 




                                       1
<PAGE>   2

Shares shall again be available for the granting of awards under the Plan,
unless the dividends were paid to the holders of such Shares.

4. ELIGIBILITY TO RECEIVE AWARDS.

Persons eligible to receive awards under the Plan (other than the Director
Program) shall be limited to those officers, other key executive employees and
directors of the Company who are in positions in which their decisions, actions
and counsel have a significant impact upon the profitability and success of the
Company.

5. FORM OF AWARDS.

Awards may be made from time to time by the Committee (other than the Director
Program) in the form of stock options to purchase Shares, stock appreciation
rights, performance units, restricted stock, or any combination of the above.
Stock options may be options which are intended to qualify as incentive stock
options ("Incentive Stock Options") within the meaning of Section 422(b) of the
Internal Revenue Code of 1986, as amended (the "Code"), or options which are not
intended to so qualify ("Non-Qualified Stock Options").

6. EMPLOYEE STOCK OPTIONS.

Stock options for the purchase of Shares granted other than under the Director
Program shall be evidenced by written agreements in such form not inconsistent
with the Plan as the Committee shall approve from time to time. Such agreement
shall contain the terms and conditions applicable to the options, including in
substance the following terms and conditions:

         (a)      Type of Option. Each option agreement shall identify the
                  options represented thereby as Incentive Stock Options or
                  Non-Qualified Stock Options, as the case may be, and shall set
                  forth the number of Shares subject to the options.

         (b)      Option Price. The option exercise price applicable to a
                  Non-Qualified Stock Option to be paid by the optionee to the
                  Company for each Share purchased upon the exercise of an
                  option shall not be less than 100 percent of the fair market
                  value of such Share on the date the Option is granted as
                  determined by the Committee.

         (c)      Exercise Term. Each option agreement shall state the period or
                  periods of time within which the option may be exercised, in
                  whole or in part, as determined by the Committee and subject
                  to such terms and conditions as are prescribed for such
                  purpose by the Committee, provided that no Incentive Stock
                  Option shall be exercisable after ten years, and no
                  Non-Qualified Stock Option shall be exercisable after ten
                  years and one day, from the date of grant thereof. The
                  Committee, in its discretion, may provide in the option
                  agreement circumstances under which the option shall become
                  immediately exercisable, in whole or in part, 




                                       2
<PAGE>   3

                  and, notwithstanding, the foregoing may accelerate the
                  exercisability of any option, in whole or in part, at any
                  time.

         (d)      Payment for Shares. The purchase price of the Shares with
                  respect to which an option is exercised shall be payable in
                  full at the time of exercise in cash, Shares at fair market
                  value owned by the Participant for a period of at least six
                  months, or a combination thereof, as the Committee may
                  determine and subject to such terms and conditions as may be
                  prescribed by the Committee for such purpose. If the purchase
                  price is paid by tendering Shares, the Committee in its
                  discretion, may grant the optionee a new stock option for the
                  number of Shares used to pay the purchase price.

         (e)      Rights Upon Termination of Employment. In the event that an
                  optionee ceases to be an employee or director of the Company
                  for any cause other than Retirement (as defined below), death
                  or Disability (as defined below), the optionee shall have the
                  right to exercise the option during its term within a period
                  of three months after such termination to the extent that the
                  option was exercisable at the time of termination, or within
                  such other period, and subject to such terms and conditions,
                  as may be specified by the Committee. (As used herein, the
                  term "Retirement" means retirement from active employment with
                  the Company on or after age 65, or such earlier age with the
                  express written consent for purposes of the Plan of the
                  Company at or before the time of such retirement, and the term
                  "Retires" has the corresponding meaning. As used herein, the
                  term "Disability" means a condition that, in the judgment of
                  the Committee, has rendered a grantee completely and
                  presumably permanently unable to perform any and every duty of
                  his regular occupation, and the term "Disabled" has the
                  corresponding meaning). In the event that an optionee Retires,
                  dies or becomes Disabled prior to the expiration of his option
                  and without having fully exercised his option, the optionee or
                  his Beneficiary (as defined below) shall have the right to
                  exercise the option during its term within a period of (i) one
                  year after termination of employment due to Retirement, death
                  or Disability, or (ii) one year after death if death occurs
                  either within one year after termination of employment due to
                  Retirement or Disability or within three months after
                  termination of employment for other reasons, to the extent
                  that the option was exercisable at the time of death or
                  termination, or within such other period, and subject to such
                  terms and conditions, as may be specified by the Committee.
                  (As used herein, the term "Beneficiary" means the person or
                  persons designated in writing by the grantee as his
                  Beneficiary with respect to an award under the Plan; or, in
                  the absence of an effective designation or if the designated
                  person or persons predecease the grantee, the grantee's
                  Beneficiary shall be the person or persons who acquire by
                  bequest or inheritance the grantee's rights in respect of an
                  award). In order to be effective, a grantee's designation of a
                  Beneficiary must be on file with the Committee before the





                                       3
<PAGE>   4

                  grantee's death, but any such designation may be revoked and a
                  new designation substituted therefor at any time before the
                  grantee's death.

         (f)      Incentive Stock Options. In the case of an Incentive Stock
                  Option, each option shall be subject to such other terms
                  conditions and provisions as the Committee determines
                  necessary or desirable in order to qualify such option as an
                  incentive stock option within the meaning of Section 422(b) of
                  the Code (or any amendment or substitute or successor thereto
                  or regulation thereunder), including in substance, without
                  limitation, the following:

                  (i)      Subject to clause (iii) below, the purchase price of
                           stock subject to an Incentive Stock Option shall not
                           be less than 100 percent of the fair market value of
                           such stock on the date the option is granted, as
                           determined by the Committee.

                  (ii)     The aggregate fair market value (determined as of the
                           time the option is granted) of the stock with respect
                           to which incentive stock options are exercisable for
                           the first time by an optionee in any calendar year
                           (under all plans of the Company and its subsidiary
                           corporations (which term, as used hereinafter, shall
                           have the meaning ascribed thereto in Section 425(f)
                           of the Code (or successor provision of similar
                           import))) shall not exceed $100,000.

                  (iii)    No Incentive Stock Option shall be granted to any
                           employee if at the time the option is granted the
                           individual owns stock possessing more than 10 percent
                           of the total combined voting power of all classes of
                           stock of the Company or of a subsidiary corporation
                           of the Company, unless at the time such option is
                           granted the option price is at least 110 percent of
                           the fair market value (as determined by the
                           Committee) of the stock subject to the option and
                           such option by its terms is not exercisable after the
                           expiration of five years from the date of grant.

                  (iv)     Directors who are not employees of the Company shall
                           not be eligible to receive Incentive Stock Options.

                  (v)      In the event of termination of employment by reason
                           of Retirement, if an Incentive Stock Option is
                           exercised after the expiration of the exercise
                           periods that apply for purposes of Section 422 of the
                           Code, the option will thereafter be treated as a
                           Non-Qualified Stock Option.

7. STOCK APPRECIATION RIGHTS.

Stock appreciation rights (SARs) shall be evidenced by written SAR agreements in
such form not inconsistent with the Plan as the Committee shall approve from
time to time. Such SAR agreements shall contain the terms and conditions
applicable to the SARs, including in substance the following terms and
conditions:

         (a)      Award. SARs may be granted in connection with a previously or
                  contemporaneously granted stock option (other than an option
                  granted pursuant to the Director Program), or independently of
                  a stock option. SARs shall entitle the grantee, subject to
                  such terms and conditions as may be determined by the
                  Committee, to receive upon exercise thereof all or a portion
                  of the excess of (i) the fair market value at the time of
                  exercise, as determined by the Committee, of a specified
                  number of Shares with respect to which the SAR is exercised,
                  over (ii) a specified price which shall not be less than 100
                  percent of the fair market value of the Shares at the time the
                  SAR is granted, or, if the SAR is granted in connection with a
                  previously issued stock option, not less than 100 percent of
                  the fair market value of the Shares at the time such option
                  was granted. Upon exercise of an SAR, the number of Shares
                  reserved for issuance hereunder shall be reduced by the number
                  of Shares covered by the SAR. Shares covered by an SAR shall
                  not be used more than once to calculate the amount to be
                  received pursuant to the exercise of the SAR.

         (b)      SARs Related to Stock Options. If an SAR is granted in
                  relation to a stock option, (i) the SAR shall be exercisable
                  only at such times, and by such persons, as the related option
                  is exercisable; (ii) the grantee's right to exercise the
                  related option shall be canceled if and to the extent that the
                  Shares subject to the option are used to calculate the amount
                  to be received upon the exercise of the related SAR; (iii) the
                  grantee's right to exercise the related SAR shall be canceled
                  if and to the extent that the Shares subject to the SAR are
                  purchased upon the exercise of the related option; and (iv)
                  the SAR shall not be transferable other than by will or by the
                  laws of descent and distribution, and shall be exercisable
                  during the lifetime of the grantee only by him.

         (c)      Term. Each SAR agreement shall state the period or periods of
                  time within which the SAR may be exercised, in whole or in
                  part, as determined by the Committee and subject to such terms
                  and conditions as are prescribed for such purpose by the
                  Committee, provided that no SAR shall be exercisable later
                  than ten years after the date of grant. The Committee may, in
                  its discretion, provide in the SAR agreement circumstances
                  under which the SARs shall become immediately exercisable, in
                  whole or in part, and may, notwithstanding the foregoing,
                  accelerate the exercisability of any SAR, in whole or in part,
                  at any time.

         (d)      Termination of Employment. SARs shall be exercisable only
                  during the grantee's employment by the Company (or, in the
                  case of a grantee who is a non-employee director, only during
                  his service as a director of the Company), except that, in the
                  discretion of the Committee, an SAR may be made exercisable
                  for up to three months after the grantee's employment (or
                  tenure as a director) is terminated for any reason other than
                  Retirement, death or Disability, and for up to one year after
                  the grantee's employment (or tenure as a director) is
                  terminated because of Retirement, death or Disability.

         (e)      Payment. Upon exercise of an SAR, payment shall be made in
                  cash, in Shares at fair market value on the date of exercise,
                  or in a combination thereof, as the Committee may determine at
                  the time of exercise.

         (f)      Other Terms. SARs shall be granted in such manner and such
                  form, and subject to such additional terms and conditions, as
                  the Committee in its sole discretion deems necessary or
                  desirable, including without limitation: (i) if granted in
                  connection with an Incentive Stock Option, in order to satisfy
                  any requirements set forth under Section 422 of the Code; or,
                  (ii) in order to avoid any liability in connection with an SAR
                  under Section 16(b) of the Securities Exchange Act of 1934, as
                  amended (the "1934 Act").

8. RESTRICTED STOCK AWARDS.

Restricted stock awards under the Plan shall consist of Shares free of any
purchase price or for such purchase price as may be established by the Committee
restricted against transfer, subject to forfeiture, and subject to such other
terms and conditions (including attainment of performance objectives) as may be
determined by the Committee. Restricted stock shall be evidenced by written
restricted stock agreements in such form not inconsistent with the Plan as the
Committee shall approve from time to time, which agreement shall contain the
terms and conditions applicable to such awards, including in substance the
following terms and conditions:

         (a)      Restriction Period. Restrictions shall be imposed for such
                  period or periods as may be determined by the Committee;
                  provided, however, that in no event (other than upon the
                  occurrence of a Change in Control or Potential Change in
                  Control) will the restrictions on such Shares lapse in full
                  earlier than three years from the date of grant; provided
                  further, however, that if such restrictions lapse as a result
                  of the attainment of performance objectives, then the
                  restrictions may not lapse earlier than one year from the date
                  of grant. The Committee, in its discretion but subject to the
                  provisos in the preceding sentence, may provide in the
                  agreement circumstances under which the restricted stock shall
                  become immediately transferable and non-forfeitable, or under
                  which the restricted stock shall be forfeited.





                                       6
<PAGE>   7

         (b)      Restrictions Upon Transfer. Restricted stock and the right to
                  vote such Shares and to receive dividends thereon, may not be
                  sold, assigned, transferred, exchanged, pledged, hypothecated,
                  or otherwise encumbered, except as herein provided, during the
                  restriction period applicable to such Shares. Notwithstanding
                  the foregoing, and except as otherwise provided in the Plan,
                  the grantee shall have all of the other rights of a
                  stockholder, including, but not limited to, the right to
                  receive dividends and the right to vote such Shares.

         (c)      Certificates. A certificate or certificates representing the
                  number of restricted Shares granted shall be registered in the
                  name of the grantee. The Committee, in its sole discretion,
                  shall determine when the certificate or certificates shall be
                  delivered to the grantee (or, in the event of the grantee's
                  death, to his Beneficiary), may provide for the holding of
                  such certificate or certificates in escrow or in custody by
                  the Company or its designee pending their delivery to the
                  grantee or Beneficiary, and may provide for any appropriate
                  legend to be borne by the certificate or certificates.

         (d)      Lapse of Restrictions. The restricted stock agreement shall
                  specify the terms and conditions upon which any restriction
                  upon restricted stock awarded under the Plan shall expire,
                  lapse, or be removed, as determined by the Committee. Upon the
                  expiration, lapse, or removal of such restrictions, Shares
                  free of the restrictive legend shall be issued to the grantee
                  of his legal representative.

9. PERFORMANCE UNITS.

Performance unit awards under the Plan shall entitle grantees to future payments
based upon the achievements of pre-established long-term performance objectives
and shall be evidenced by written performance unit agreements in such form not
inconsistent with this Plan as the Committee shall approve from time to time.
Such agreements shall contain the terms and conditions applicable to the
performance unit awards, including in substance the following terms and
conditions:

         (a)      Performance Period. The Committee shall establish with respect
                  to each unit award a performance period of not fewer than two
                  years.

         (b)      Unit Value. The Committee shall establish with respect to each
                  unit award value for each unit which shall not thereafter
                  change, or which may vary thereafter pursuant to criteria
                  specified by the Committee.

         (c)      Performance Targets. The Committee shall establish with
                  respect to each unit award maximum and minimum performance
                  targets to be achieved during the applicable performance
                  period. Achievement of maximum targets shall entitle grantees
                  to payment with respect to the full value of a unit award.
                  Grantees shall 





                                       7
<PAGE>   8

                  be entitled to payment with respect to a portion of a unit
                  award according to the level of achievement of targets as
                  specified by the Committee for performance which achieves or
                  exceeds the minimum target but fails to achieve the maximum
                  target.

         (d)      Performance Measures. Performance targets established by the
                  Committee shall relate to corporate, subsidiary, division, or
                  unit performance and may be established in terms of growth in
                  gross revenue, earnings per share, ratios of earnings to
                  equity or assets, or such other measures or standards as may
                  be determined by the Committee in its discretion. Multiple
                  targets may be used and may have the same or different
                  weighting, and they may relate to absolute performance or
                  relative performance measured against other companies or
                  businesses.

         (e)      Adjustments. At any time prior to the payment of a unit award,
                  the Committee may adjust previously established performance
                  targets or other terms and conditions, including the Company's
                  or other corporations' financial performance for Plan
                  purposes, to reflect major unforeseen events such as changes
                  in laws, regulations or accounting practices, mergers,
                  acquisitions or divestitures or other extraordinary unusual or
                  nonrecurring items or events.

         (f)      Payment of Unit Awards. Following the conclusion of each
                  performance period, the Committee shall determine the extent
                  to which performance targets have been attained and any other
                  terms and conditions satisfied for such period. The Committee
                  shall determine what, if any, payment is due on the unit award
                  and whether such payment shall be made in cash, Shares, or a
                  combination thereof. Payment shall be made in a lump sum or
                  installments, as determined by the Committee, commencing as
                  promptly as practicable following the end of the performance
                  period unless deferred subject to such terms and conditions
                  and in such form as may be prescribed by the Committee.

         (g)      Termination of Employment. In the event that a grantee ceases
                  to be employed by the Company prior to the end of the
                  performance period by reason of death, Disability, or
                  Retirement with the consent of the Company, any unit award, to
                  the extent earned under the applicable performance targets,
                  shall be payable at the end of the performance period
                  according to the portion of the performance period during
                  which the grantee was employed by the Company, provided that
                  the Committee shall have the power to provide for an
                  appropriate settlement of a unit award before the end of the
                  performance period. Upon any other termination of employment,
                  participation shall terminate forthwith and all outstanding
                  unit awards shall be canceled.

10. LOANS AND SUPPLEMENTAL CASH.

The Committee, in its sole discretion to further the purpose of the Plan, may
provide for supplemental cash payments or loans to individuals in connection
with all or any part of an award under the Plan. Supplemental cash payments
shall be subject to such terms and conditions as shall be prescribed by the
Committee at the time of grant, provided that in no event shall the amount of
payment exceed:

         (a)      In the case of an option, the excess fair market value of a
                  Share on the date of exercise over the option price multiplied
                  by the number of Shares for which such option is exercised, or

         (b)      In the case of an SAR, performance unit, or restricted stock
                  award, the value of the Shares and other consideration issued
                  in payment of such award.

Any loan shall be evidenced by a written loan agreement or other instrument in
such form and containing such terms and conditions (including, without
limitation, provisions for interest, payment schedules, collateral, forgiveness
or acceleration) as the Committee may prescribe from time to time.

11. DIRECTOR PROGRAM.

         (a)      Eligible Directors. Each member of the Board of Directors who
                  is not a full-time employee of the Company is an "Eligible

         (b)      Administration. The Director Program shall be administered by
                  the Board of Directors. Subject to the provisions of the
                  Director Program, the Board shall be authorized to:

                  (i)      adopt, revise and repeal such administrative rules,
                           guidelines and practices governing the Director
                           Program as it shall from time to time deem advisable;

                  (ii)     interpret the terms and provisions of the Director
                           Program and any option issued under the Director
                           Program (and any agreements relating thereto), and
                           otherwise settle all claims and disputes arising
                           under the Director Program;

                  (iii)    delegate responsibility and authority for the

                           appoint employees and officers of the Company to act
                           on its behalf, and employ persons to assist in the
                           fulfilling of its responsibilities under the Director
                           Program; and

<PAGE>   10

                  (iv)     otherwise supervise the administration of the
                           Director Program; provided, however, that the Board
                           of Directors shall have no discretion with respect to
                           the selection of Eligible Directors to receive
                           options hereunder, the number of Shares covered by
                           such option or the price or timing of any options
                           granted hereunder; provided, further, that any action
                           by the Board of Directors relating to the Director
                           Program will be taken only if approved by the
                           affirmative vote of a majority of the directors who
                           are not then eligible to participate under the
                           Director Program.

         (c)      Option Grants.

                  (i)      Number of Options Granted. The following number of
                           Director Options are hereby granted to each Eligible
                           Director under the Director Program:

                           (A)      As of the date of Board approval of the
                                    Director Program, a Director Option to

                                    person who on that date is an incumbent
                                    Eligible Director.

                           (B)      With respect to each person who first
                                    becomes an Eligible Director after the date
                                    of Board approval of the Director Program, a
                                    Director Option to purchase 5,000 Shares is
                                    granted as of the date such person first
                                    becomes an Eligible Director.

                           (C)      As of the date of every third annual meeting
                                    of the Company's shareholders following the
                                    grant of a Director Option to an Eligible
                                    Director pursuant to section (A) or (B)
                                    above, and provided that such Eligible

                  (iv)     Exercisability. A Director Option shall be
                           exercisable during its term, 33.33% on the first
                           anniversary of the date of grant, an additional
                           33.33% on the second anniversary of the date of
                           grant, and the remaining 33.33% on the third
                           anniversary of the date of grant. The Director
                           Options granted on the date the Director Program was
                           approved by the Board vest 33.33% on December 19,
                           1995, 1996, and 1997.

         (e)      Method of Exercise. Director Options may be exercised, in
                  whole or in part, at any time and from time to time during the
                  relevant exercise period, by giving written notice of exercise
                  to the Company specifying the number of Shares to be
                  purchased. Such notice shall be accompanied by payment in full
                  of the purchase price, either in cash or by certified or bank
                  check, or such other instrument as the Board of Directors may
                  accept. Payment in full or in part may also be made in the
                  form of unrestricted Shares already owned by the Director (and
                  based upon the fair market value of the Shares so tendered as
                  of the date the Director Option is exercised, as determined by
                  the Board of Directors). No Shares shall be issued until full
                  payment therefor has been made. Eligible Directors shall
                  generally have the rights to dividends or other rights of a
                  stockholder with respect to Shares subject to the Director
                  Option when the Eligible Director has given notice as to
                  exercise, has paid in full for such shares and, if requested,
                  has given any representations required by the Board of
                  Directors.

         (f)      Termination by Reason of Death. If an optionee ceases to be an
                  Eligible Director by reason of death, any Director Option held
                  by such optionee may thereafter be exercised to the extent
                  then exercisable, by the legal representative of the estate or
                  by the legatee of the Eligible Director under the will of the
                  Eligible Director, for a period of one year from the date of
                  such death or until the expiration of the stated term of such
                  Director Option, whichever period is shorter.

         (g)      Termination by Reason of Disability. If an optionee ceases to
                  be an Eligible Director by reason of disability, any Director
                  Option held by such optionee may thereafter be exercised by
                  the optionee, to the extent it was exercisable at the time of
                  termination, for a period of one year from the date of such
                  termination or until the expiration of the stated term of such
                  Director Option, whichever period is shorter, provided,
                  however, that if the optionee dies within such one-year
                  period, any unexercised Director Option held by such optionee
                  shall thereafter be exercisable to the extent it was
                  exercisable at the time of death for a period of one year from
                  the date of such death or until the expiration of the stated
                  term of such Director Option, whichever period is shorter.

         (h)      Other Termination. If an optionee ceases to be an Eligible
                  Director for any reason other than death or disability (except
                  as a result of becoming an employee of the 





                                       11
<PAGE>   12

                  Company), any Director Option held by such optionee may
                  thereafter be exercised by the optionee, to the extent it was
                  exercisable at the time of such termination, for a period of
                  three months from the date of such termination or the
                  expiration of the stated term of such Director Option,
                  whichever period is shorter; provided, however, that if the
                  optionee dies within such three-month period, any unexercised
                  Director Option held by such optionee shall thereafter be
                  exercisable, to the extent to which it was exercisable at the
                  time of death, for a period of one year from the date of such
                  death or until the expiration of the stated term of the
                  Director Option, whichever period is shorter. If an optionee
                  ceases to be an Eligible Director by reason of his becoming an
                  employee of the Company and his employment with the Company is
                  subsequently terminated, any Director Option held by such
                  optionee may thereafter be exercised by the optionee, to the
                  extent that it was exercisable at the time of such
                  termination, for a period of three months from the date of
                  such termination or the expiration of the stated term of the
                  Director Option, whichever period is shorter; provided,
                  however, that if the optionee dies within such three-month
                  period, any unexercised Option held by such optionee shall
                  thereafter be exercisable, to the extent to which it was
                  exercisable at the time of death, for a period of one year
                  from the date of such death or until the expiration of the
                  stated term of the Director Option, whichever period is
                  shorter.

12. GENERAL RESTRICTIONS.

Each award under the Plan shall be subject to the requirement that if at any
time the Company shall determine that (i) the listing, registration or
qualification of the Shares subject or related thereto upon any securities
exchange or under any state or federal law, or (ii) the consent or approval of
any regulatory body, or (iii) an agreement by the recipient of an award with
respect to the disposition of Shares, or (iv) the satisfaction of withholding
tax or other withholding liabilities is necessary or desirable as a condition of
or in connection with the granting of such award or the issuance or purchase of
Shares thereunder, such award shall not be consummated in whole or in part
unless such listing, registration, qualification, consent, approval, agreement,
or withholding shall have been effected or obtained free of any conditions not
acceptable to the Company. Any such restriction affecting an award shall not
extend the time within which the award may be exercised; and neither the Company
nor its directors or officers nor the Committee shall have any obligation or
liability to the grantee or to a Beneficiary with respect to any Shares with
respect to which an award shall lapse or with respect to which the grant,
issuance or purchase of Shares shall not be effected, because of any such
restriction.

13. SINGLE OR MULTIPLE AGREEMENTS.

Multiple awards, multiple forms of awards, or combinations thereof may be
evidenced by a single agreement or multiple agreements, as determined by the
Committee.






                                       12
<PAGE>   13

14. RIGHTS OF THE SHAREHOLDER.

The recipient of any award under the Plan, shall have no rights as a shareholder
with respect thereto unless and until certificates for Shares are issued to him,
and the issuance of Shares shall confer no retroactive right to dividends.

15. RIGHTS TO TERMINATE EMPLOYMENT.

Nothing in the Plan or in any agreement entered into pursuant to the Plan shall
confer upon any person the right to continue in the employment of the Company or
affect any right which the Company may have to terminate the employment of such
person.

16. WITHHOLDING.

         (a)      Prior to the issuance or transfer of Shares under the Plan,
                  the recipient shall remit to the Company an amount sufficient
                  to satisfy any federal, state or local withholding tax
                  requirements. Other than with respect to awards under the
                  Director Program, the recipient may satisfy the withholding
                  requirement in whole or in part by electing to have the
                  Company withhold Shares having a value equal to the amount
                  required to be withheld. The value of the Shares to be
                  withheld shall be the fair market value, as determined by the
                  Committee, of the stock on the date that the amount of tax to
                  be withheld is determined (the "Tax Date"). Such election must
                  be made prior to the Tax Date, must comply with all applicable
                  securities law and other legal requirements, as interpreted by
                  the Committee, and may not be made unless approved by the
                  Committee, in its discretion.

         (b)      Whenever payments to a grantee in respect of an award under
                  the Plan to be made in cash, such payments shall be net of the
                  amount necessary to satisfy any federal, state or local
                  withholding tax requirements.

17. NON-ASSIGNABILITY.

No award under the Plan shall be sold, assigned, transferred, exchanged,
pledged, hypothecated, or otherwise encumbered, other than by will or by the
laws of descent and distribution, or, with respect to Awards other than
Incentive Stock Options, by such other means as the Committee (or the Board of
Directors, in the case of the Director Program) may approve. Except as otherwise
provided herein or a permitted transferee approved by the Committee (or the
Board of Directors, in the case of the Director Program) during the life of the
recipient, such Award shall be exercisable only by such person or by such
person's guardian or legal representative.

18. NON-UNIFORM DETERMINATIONS.

The Committee's determinations under the Plan (including without limitation
determinations of the persons to receive awards, the form, amount and timing of
such awards, the terms and provisions of such awards and the agreements
evidencing same, and the establishment of values and performance targets) need
not be uniform and may be made selectively among persons who receive, or are
eligible to receive, awards under the Plan, whether or not such persons are
similarly situated.

                  Potential Change in Control (as defined) the following
                  acceleration and valuation provisions shall apply unless the

                  (ii)     Any restrictions and deferral limitations applicable

                           Stock-based awards, in each case to the extent not
                           already vested under the Plan, shall lapse and such

                           Control or such Potential Change in Control is
                           determined to have occurred or such other date as the
                           Committee may determine prior to the Change in

                           initiated by the Company in the ordinary course of

                           were directors of the Company at the beginning of an

                           Change in Control of the Company; or

                  (ii)     The acquisition of beneficial ownership, directly or

                           or any employee benefit plan of the Company or its
                           subsidiaries (including any trustee of such plan
                           acting as such trustee)) of securities of the Company
                           representing 5 percent or more of the combined voting
                           power of the Company's outstanding securities and the
                           adoption by the Board of Directors of a resolution to
                           the effect that a Potential Change in Control of the
                           Company has occurred for purposes of this Plan.

<PAGE>   16

                  occurrence of the Potential Change in Control event), in each
                  case determined by the Committee except that, in the case of
                  Incentive Stock Options and SARs relating to Incentive Stock
                  Options, such price shall be based only on transactions
                  reported for the date on which the optionee exercises such
                  SARs or, where applicable, the date on which a cash out occurs
                  under Section 19(a)(iii).

20. NON-COMPETITION PROVISION.

Unless the award agreement relating to a stock option, SAR, restricted stock or
performance unit specifies otherwise, a grantee shall forfeit all un-exercised,
unearned and/or unpaid awards, including, but not by way of limitation, awards
earned but not yet paid, all unpaid dividends and dividend equivalents, and all
interest, if any, accrued on the foregoing if, (i) in the opinion of the
Committee, the grantee without the written consent of the Company, engages
directly or indirectly in any manner or capacity as principal, agent, partner,
officer, director, employee or otherwise, in any business or activity
competitive with the business conducted by the Company or any of its
subsidiaries; or (ii) the grantee performs any act or engages in any activity
which in the opinion of the Chief Executive Officer of the Company is inimical
to the best interests of the Company.

21. ADJUSTMENTS.

In the event of any change in the outstanding common stock of the Company, by
reason of a stock dividend or distribution, recapitalization, merger,
consolidation, reorganization, split-up, combination, exchange or Shares or the
like, the Board of Directors, in its discretion, may adjust proportionately the
number of Shares which may be issued under the Plan, the number of Shares
subject to outstanding awards, and the option exercise price of each outstanding
option, and may make such other changes in outstanding, options, SARs,
performance units and restricted stock awards, as it deems equitable in its
absolute discretion to prevent dilution or enlargement of the rights of
grantees, provided that any fractional Shares resulting from such adjustments
shall be eliminated.

22. AMENDMENT.

The Board of Directors may terminate, amend, modify or suspend the Plan at any
time, except that no termination, amendment, modification or suspension shall be
effective without the authorization of the holders of a majority of Company's
outstanding Shares, if such authorization is required to comply with any law,
regulation or stock exchange rule. No termination, modification, amendment or
suspension of the Plan shall adversely affect the rights of any grantee or
Beneficiary under an award previously granted, unless the grantee or Beneficiary
shall consent; but it shall be conclusively presumed that any adjustment
pursuant to paragraph 21 hereof does not adversely affect any such right.

23. EFFECT ON OTHER PLANS.

Participation in this Plan shall not affect a grantee's eligibility to
participate in any other benefit or incentive plan of the Company. Any awards
made pursuant to this Plan shall not be used in determining the benefits
provided under any other plan of the Company unless specifically provided
therein.

24. EFFECTIVE DATE AND DURATION OF THE PLAN.

The initial effective date of the Plan was December 16, 1992. Unless it is
sooner terminated in accordance with paragraph 22 hereof, the Plan shall remain
in effect until all awards under the Plan have been satisfied by the issuance of
Shares or payment of cash or have expired or otherwise terminated, but no award
shall be granted after December 16, 2002.

25. UNFUNDED PLAN.

The Plan shall be unfunded, except to the extent otherwise provided in
accordance with Section 8 hereof. Neither the Company nor any affiliate shall be
required to segregate any assets that may be represented by stock options, SARs,
or performance units, and neither the Company nor any affiliate shall be deemed
to be a trustee of any amounts to be paid under any stock option, SAR or
performance unit. Any liability of the Company or any affiliate to pay any
grantee or Beneficiary with respect to an option, SAR or performance unit shall
be based solely upon any contractual obligations created pursuant to the
provisions of the Plan; no such obligations will be deemed to be secured by a
pledge or encumbrance on any property of the Company or an affiliate.

26. GOVERNING LAW.

The Plan shall be construed and its provisions enforced and administered in
accordance with the laws of the State of Tennessee, except to the extent that
such laws may be superseded by any federal law.

On December 12, 1997, the Board of Directors approved an amendment to the Long
Term Incentive Plan that increased the Shares available for grant thereunder
from 6,000,000 to 7,500,000. In addition, the Board of Directors has approved
certain other technical amendments. The proposal to approve the Company's 1993
Long Term Incentive Plan, as amended, will be acted upon by the Company's
Shareholders at the annual meeting on May 20, 1998.

the three years in the period ended December 31, 1997. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Sofamor
Danek Group, Inc. and Subsidiaries as of December 31, 1997 and 1996, and the
results of their consolidated operations and their cash flows for each of the
three years in the period ended December 31, 1997 in conformity with generally
accepted accounting principles.

NOTE TO CONSOLIDATED FINANCIAL STATEMENTS
SOFAMOR DANEK GROUP, INC. AND SUBSIDIARIES
(IN THOUSANDS, EXCEPT FOR SHARES AND PER SHARE DATA)

1.       ORGANIZATION, BASIS OF PRESENTATION AND NATURE OF OPERATIONS

         ORGANIZATION

         The consolidated financial statements of Sofamor Danek Group, Inc. (the
         "Company") include the accounts of the Company and its subsidiaries
         over which it maintains control. Minority interest represents minority
         shareholders' proportionate share of their equity ownership in the
         subsidiaries. All significant intercompany balances, transactions and
         profits have been eliminated in consolidation.

         BASIS OF PRESENTATION

         The consolidated financial statements are prepared on the basis of
         generally accepted accounting principles. The preparation of financial
         statements in conformity with generally accepted accounting principles
         requires management to make estimates and assumptions that affect the
         reported amounts of assets and liabilities at December 31, 1997 and
         1996 and reported amounts of revenues and expenses for each of the
         three years in the period ended December 31, 1997. Significant
         estimates include those made for product liability litigation, the
         allowance for doubtful accounts, inventory reserves for excess,
         obsolete and damaged products, and accumulated depreciation and
         amortization. Actual results could differ from those estimates made by
         management.

         NATURE OF OPERATIONS

         The Company is primarily involved in developing, manufacturing and
         marketing devices, instruments, computer-assisted visualization
         products and biomaterials used in the treatment of spinal and cranial
         disorders. The Company has subsidiaries located throughout North
         America, Europe, Asia and Australia and has manufacturing facilities
         located in Indiana, Florida, Colorado and France. Products are sold
         primarily to hospitals, either directly or through distributors.

         A significant portion of the Company's revenue is derived from its
         international operations. As a result, the Company's operations and
         financial results could be affected by international factors such as
         changes in foreign currency exchange rates or weak economic conditions
         in the international markets in which the Company distributes its
         products. In addition, inherent in the accompanying consolidated
         financial statements are certain risks and uncertainties. These risks
         and uncertainties include, but are not limited to: timely development
         and acceptance of new products, impact of competitive products, timely
         receipt of regulatory clearances required for new products, regulation
         of current products, potential impact on healthcare cost containment
         proposals on profitability, product


                                                                              18
<PAGE>   8
         obsolescence, the availability of product liability insurance,
         disposition of certain litigation matters and cash balances in excess
         of federally insured limits.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         CASH EQUIVALENTS

         The Company considers all highly liquid investments with a remaining
         maturity of three months or less when purchased to be cash equivalents.

         OTHER RECEIVABLES

         Other receivables consist primarily of amounts due from insurance
         carriers under the Company's product liability policies.

         INVENTORIES AND LOANER INVENTORIES

         Inventories and loaner inventories are stated at the lower of cost
         (determined principally by the first-in, first-out method) or market.
         The Company maintains a reserve for its estimate of excess, obsolete
         and damaged goods based on historical and forecasted usage.

         PROPERTY, PLANT AND EQUIPMENT

         Property, plant and equipment, including certain equipment acquired
         under capital leases, are stated at cost. Property and equipment are
         depreciated on a straight-line basis over their estimated useful lives
         which range from 3 to 40 years. Assets acquired under capital leases
         are amortized over the term of the underlying lease. Amortization
         expense of assets under capital leases and depreciation expense for the
         years ended December 31, 1997, 1996 and 1995 totaled $7,011, $5,449 and
         $4,366, respectively.

         Amounts expended for maintenance and repairs are charged to expense as
         incurred. Upon disposition, both the related cost and accumulated
         depreciation accounts are relieved and the related gain or loss is
         credited or charged to operations.

         INVESTMENTS

         Investments represent the Company's investments in unconsolidated
         affiliates. Investments over which the Company exerts significant
         influence, but does not control the financial and operational
         direction, are accounted for using the equity method of accounting. All
         other investments are recorded at cost.



                                                                              19
<PAGE>   9
      REVENUE RECOGNITION

      The Company derives revenues from both sales of products and certain
      service functions. Sales are recognized primarily upon the shipment of
      products to the customer or distributor. The revenues from services are
      recognized at the time services are rendered.

      Concentration of credit risk with respect to trade accounts receivable is
      generally diversified due to the large number of entities comprising the
      Company's customer base. The Company performs ongoing credit evaluations
      and provides an allowance for potential credit losses against the portion
      of accounts receivable which is estimated to be uncollectible. Such losses
      have historically been within management's expectations.

      INTEREST RATE SWAP AGREEMENTS

      During 1997, the Company entered into certain interest rate swap
      agreements to reduce the impact of changes in interest rates on its
      floating rate debt. The agreements are contracts to exchange floating rate
      for fixed interest payments periodically over the life of the agreements
      without the exchange of the underlying notional amounts. The notional
      amounts of interest rate agreements are used to measure the interest to be
      received or paid and do not represent the amount of exposure to credit
      loss. The differential paid or received on interest rate agreements is
      recognized as an adjustment to interest expense.

      INCOME TAXES

      The provision for income taxes and corresponding balance sheet accounts
      are determined in accordance with SFAS No. 109, "Accounting for Income
      Taxes" ("SFAS 109"). Under SFAS 109, deferred tax liabilities and assets
      are determined based on temporary differences between the bases of certain
      assets and liabilities for income tax and financial reporting purposes.

      The deferred tax assets and liabilities are classified according to the
      financial statement classification of the assets and liabilities
      generating the differences. Valuation allowances are established when
      necessary to reduce deferred tax assets to the amount expected to be
      realized.

      FOREIGN CURRENCY TRANSLATION

      All balance sheet accounts denominated in a foreign currency are
      translated into U.S. dollars at the current exchange rate as of the end of
      the accounting period. Income statement items are translated at
      weighted-average currency exchange rates. The Company will continue to be
      exposed to the effects of foreign currency translation adjustments. Gains
      and losses resulting from foreign currency transactions denominated in a
      currency other than the functional currency are included in net income and
      amounted to a net loss in 1997 of $2,012 and net gains during 1996 and
      1995 of $632 and $827, respectively. Gains and losses relative to
      intercompany foreign currency transactions, for which settlement is 

                                                                              20
<PAGE>   10
      not planned or anticipated in the foreseeable future, are excluded from
      net income and reflected as cumulative translation adjustments.

3.    INVENTORIES AND LOANER INVENTORIES

      Net inventories at December 31, 1997 and 1996 consist of the following:

      be loaned to customers.

4.    ACQUISITIONS

      The Company completed one acquisition in 1997 and four acquisitions in
      1996. These acquisitions have been accounted for utilizing the purchase
      method of accounting. Accordingly, the results of operations of the
      acquired businesses, which are not significant to the Company's
      consolidated results of operations, have been included in the accompanying
      consolidated financial statements from their respective dates of
      acquisition.

      In December 1997, the Company acquired certain net assets of MAN Ceramics
      GmbH, a privately held company located in Germany. MAN Ceramics designs,
      manufactures and markets carbon fiber interbody fusion devices.

      In December 1996, the Company acquired all of the capital stock of
      Colorado S.A., a privately held company located in France. Colorado, S.A.
      designs and markets certain spinal devices used in the surgical treatment
      of deformities and lumbar disorders of the spine.

      In July 1996, the Company acquired all of the capital stock of MedNext,
      Inc., a privately held company located in West Palm Beach, Florida that
      designs, manufactures and markets powered surgical instrumentation and
      accessories for surgical specialties.

      In July 1996, the Company acquired the net assets of TiMesh, Inc., a
      privately held company located in Las Vegas, Nevada. The net assets
      acquired are used in the design, manufacture, and marketing of titanium
      plates and titanium alloy screws.

                                                                              21
<PAGE>   11
      In March 1995, the Company purchased 19.5% of the outstanding stock of
      Surgical Navigation Technologies, Inc. ("SNT"), a privately held company
      located in Broomfield, Colorado. In conjunction with the purchase, the
      Company acquired the exclusive worldwide license to manufacture and
      distribute SNT products relating to frameless stereotactic surgery in the
      spinal and neurological fields. In May 1996, the Company acquired the
      remaining 80.5% of the outstanding stock of SNT.

      The purchase agreements for two of these acquisitions contain provisions
      which provide for contingent payments to the former shareholders of each
      entity based upon certain calculations relative to revenues and earnings,
      as defined, through 1999. Such payments will be reflected as purchase
      price adjustments. The Company recorded adjustments to the purchase price
      of these acquisitions of $5,072 and $4,174, in 1997 and 1996,
      respectively. The Company is unable to determine whether such payments
      will be required for the years 1998 and 1999.

      The estimated fair values assigned to the assets and liabilities acquired
      were as follows:

5.    INTANGIBLE ASSETS

      Identifiable intangible assets and goodwill are recorded and amortized
      over their estimated economic lives or periods of future benefit. The
      Company amortizes goodwill on a straight-line basis over the estimated
      period of benefit ranging from 15 to 20 years. Other identifiable
      purchased intangible assets are amortized on a straight-line basis over
      their estimated period of benefit ranging from 1 to 12 years. The lives
      established for these assets are a composite of many factors which are
      subject to change because of the nature of the Company's operations. This
      is particularly true for goodwill which reflects value attributable to the
      going concern nature of acquired businesses, the stability of their
      operations, market presence and reputation. Accordingly, the Company
      evaluates the continued appropriateness of these lives and recoverability
      of the carrying value of such assets based upon the latest available
      economic factors and circumstances, compared with the undiscounted
      cashflows associated with the underlying asset. Impairment of value, if
      any, is recognized in the period in which it is determined. The Company
      does not believe that there are any facts or circumstances indicating
      impairment of identifiable intangible assets and goodwill, at December 31,
      1997.

                                                                              22

6.    LICENSE AGREEMENT ACQUISITION CHARGE

      During 1995, the Company entered into a license agreement (the
      "Agreement") with Genetics Institute, Inc. ("G.I.") to provide biological
      products for use in spinal applications. The Agreement provides exclusive
      North American distribution rights to the Company and requires annual
      payments through 1998 totaling $50,000. The Company charged $45,337 to
      operations during 1995 as purchased research and development. This charge
      represents the net present value of the total required payments pursuant
      to the Agreement plus related transaction costs. The liability recorded at
      December 31, 1997 represents the present value of the Company's remaining
      obligation under the terms of the Agreement.

7.    FOREIGN OPERATIONS

      The Company operates in predominately one industry. A summary of the
      Company's operations by geographical areas for the three years ended

8.    NOTES PAYABLE AND LINES OF CREDIT

      At December 31, 1997 and 1996, the Company had a loan agreement with a
      syndicate of U.S. banks, which provided for borrowings of up to $100,000
      and $50,000, respectively, under a revolving line of credit. The Company
      can borrow funds under the loan agreement denominated in U.S. Dollars,
      French Francs, or Japanese Yen. U.S. Dollar, French Franc, and Japanese
      Yen borrowings under the line of credit bear interest at rates of 0.625%
      above each of the 30-day adjusted LIBOR rate (5.7188% at December 31,
      1997), PIBOR rate (3.5664% at December 31, 1997) and TIBOR rate (1.0007%
      at December 31, 1997), respectively, and interest is payable monthly. The
      Company must also pay a quarterly fee of 0.125% per annum on the unused
      portion of the commitment. The loan agreement contains covenants which
      include certain restrictions, such as minimum levels of tangible net worth
      and maintenance of a certain debt service coverage ratio. The Company had
      the equivalent of $55,573 and $35,087 outstanding under the revolving line
      of credit at 

                                                                              24
<PAGE>   14
      December 31, 1997 and 1996, respectively. During July, 1997, the Company
      renegotiated its uncollateralized revolving line of credit. The revision
      extended the maturity of this instrument to July 2000. At December 31,
      1997, the balance sheet of the Company reflected the outstanding balance
      as long-term debt.

      As of December 31, 1997, the Company had entered into interest rate swap
      agreements with certain financial institutions. The agreements effectively
      fix the interest rate on floating rate debt at a rate of 7.625% and 6.965%
      for notional principal amounts of $12,000 and $18,000, respectively.

      At December 31, 1997, the Company also had loan agreements with various
      international banks. The aggregate maximum borrowings available under
      these committed lines of credit were equivalent to approximately $15,925
      and bear interest at rates ranging from 0.25% to 20.0%. The Company had
      approximately $11,731 and $15,120, outstanding under the revolving lines
      of credit and various other short-term borrowings at December 31, 1997 and
      1996, respectively.

      The Company's weighted average interest rate on lines of credit and
      short-term borrowings was approximately 6.4% and 6.5% at December 31, 1997
      and 1996, respectively.

      The Company has two stand-by letters of credit totaling $3,700. Amounts
      available under the Company's $100,000 revolving line of credit are
      reduced by the letters of credit.

9.    LONG-TERM DEBT

      In connection with the G.I. Agreement, the Company has recorded long-term
      debt equal to the net present value of the future annual payments
      (calculated at inception based on the Company's implicit borrowing rate of
      6.75%). Interest expense is recognized ratably over the term of the
      agreement. The Company recognized interest expense of $1,012, $1,880, and
      $1,650 relative to this agreement during 1997, 1996 and 1995,
      respectively.

12.   RELATED PARTY TRANSACTIONS

      At December 31, 1995, the Company had loans of $4,165 to the Company's
      Chairman and Chief Executive Officer ("Chairman") for the purchase of
      common stock of the Company and for personal income taxes resulting from
      the exercise of common stock options and the 

                                                                              28
<PAGE>   18
      vesting of certain restricted stock. Interest was charged at the
      applicable short-term federal rates as prescribed by the Internal Revenue
      Service and was due annually. During 1996, the Company's Board of
      Directors approved an amendment to the Chairman's loan forgiveness
      arrangements providing for forgiveness of the loans and the related
      compensation expense in equal increments beginning in 1996 through 2005
      and for paying all future applicable taxes and interest on the loans. This
      forgiveness is conditional upon the Chairman remaining continuously
      employed by the Company for the next ten years and certain performance
      criteria. In the event of a change in control of the Company, the loans
      are immediately forgiven. The balance of the loans at December 31, 1997
      and 1996 was $3,265 and $3,715, respectively. The loans are collateralized
      by 200,000 shares of common stock.

13.   COMMITMENTS AND CONTINGENCIES

      The Company and its subsidiaries lease certain equipment and facilities
      under non-cancelable operating leases expiring in 2008. The future annual
      minimum rent payments under these leases at December 31, 1997 are as

</TABLE>

      Rent expense for 1997, 1996 and 1995, including month-to-month leases, was
      approximately $2,975, $1,914 and $903, respectively.

      The Company has agreements with certain entities which provide the Company
      the rights to manufacture and market certain spinal system products
      developed and patented by these entities. The agreements generally provide
      for royalty payments ranging from 1% to 10% of the net selling prices (as
      defined by the agreements) of all such products sold or for required
      royalty payments based on a predefined fee. These agreements are in force
      as long as the Company sells the related products. Royalty expense was
      $9,134, $6,768 and $5,907 in 1997, 1996 and 1995, respectively.

      In 1996, the IRS began an examination of the Company's federal income tax
      returns. The years under examination are 1993, 1994 and 1995. Management
      believes that the resolution of any issues that may be developed as a
      result of the examination will not have a significant impact on the
      Company's results of operations or financial condition.

                                                                              29

14.   LITIGATION

      The Company is involved from time to time in litigation on various matters
      which are routine to the conduct of this business, including product
      liability and intellectual property cases.

      PRODUCT LIABILITY LITIGATION

      Beginning in 1994, the Company and other spinal implant manufacturers were
      named as defendants in a number of product liability lawsuits brought in
      various federal and state courts around the country. These lawsuits allege
      that plaintiffs were injured by spinal implants manufactured by the
      Company and others. The essence of the plaintiff's claims appears to be
      that the Company (including Sofamor and its former U.S. distributor)
      marketed some of its spinal systems for pedicle fixation in contravention
      of FDA rules and regulations (governing marketing and labeling of medical
      devices), that pedicle fixation has not been proven safe and effective in
      the context of FDA labeling standards, that some or all of the spinal
      systems are defectively designed and manufactured and that plaintiffs have
      suffered a variety of injuries as a result of their physicians' use of
      such systems in pedicle fixation. The Company has also been named as a
      defendant in a number of lawsuits instituted by plaintiffs who have
      received spinal implants manufactured by other manufacturers and in which
      the Company is alleged to have participated in a conspiracy among doctors,
      manufacturers, hospitals, teaching institutions, professional societies
      and others to promote, in violation of applicable law, the use of spinal
      implants.

      In a number of cases, plaintiffs have sought to proceed as representatives
      of classes of spinal implant recipients. All efforts to obtain class
      certification have been denied or withdrawn, except with respect to a
      class-action settlement entered into between the plaintiffs and another
      spinal implant manufacturer, AcroMed Corporation (see below under the
      heading entitled "AcroMed Corporation Settlement"). Some plaintiffs have
      filed individual lawsuits, whereas other lawsuits list multiple plaintiffs
      and, in certain instances, multiple lawsuits have been filed on behalf of
      the same individual plaintiffs. Plaintiffs typically seek relief in the
      form of monetary damages, often in unspecified amounts. Many of the
      plaintiffs only allege as monetary damage an amount in excess of the
      jurisdictional minimum for the court in which the case has been filed. A
      few suits also name as defendants various officers and directors of the
      Company.

      As of December 31, 1997, approximately 2,800 plaintiffs were joined in
      lawsuits against the Company. The Company is also named as a defendant of
      lawsuits involving about 2,600 claimants where the Company is alleged to
      have conspired with competitors and others illegally to promote the use of
      spinal implant systems.

      The Company believes that it has defenses, including, without limitation,
      defenses based upon the failure of a cause of action to exist where no
      malfunction of the implant has occurred or the plaintiff has suffered no
      injury attributable to the Company's product, the expiration of the
      applicable statute of limitations and the learned intermediary defense.
      The 

                                                                              30
<PAGE>   20
      Company has asserted and will continue to assert these defenses primarily
      through the filing of dispositive motions. The Company believes that all
      product liability lawsuits currently pending against it are without merit
      and will continue to defend against them vigorously.

      FEDERAL MULTIDISTRICT LITIGATION (MDL 1014)

      On August 4, 1994, the Federal Judicial Panel for Multidistrict Litigation
      ordered all federal court lawsuits to be transferred to and consolidated
      for pretrial proceedings, including the determination of class
      certification, in the United States District Court for the Easter District
      of Pennsylvania in Philadelphia (the "Multidistrict Litigation"). Lawsuits
      filed in federal court after August 4, 1994 have also been transferred to
      and consolidated in the Multidistrict Litigation in the Easter District of
      Pennsylvania. In addition, a number of lawsuits filed in state courts
      around the country were removed to federal courts and then transferred
      into the Multidistrict Litigation. On February 22, 1995, Chief Judge
      Emeritus, Louis C. Bechtle, denied class certification. A large number of
      plaintiffs filed individual lawsuits as a result of the denial of class
      certification. In some instances, lawsuits that had been removed and
      transferred into the Multidistrict Litigation have been remanded to the
      state courts in which they were filed because there was no federal court
      jurisdiction. As of December 31, 1997, the Company is a defendant in
      approximately 920 individual claims and 1,065 conspiracy claims
      consolidated in the Multidistrict Litigation. On April 16, 1997, Judge
      Bechtle dismissed conspiracy claims alleging fraud on the FDA, but
      deferred the remaining conspiracy claims for later consideration by the
      federal trial courts to whom the cases will be remanded for trial.

      Discovery has been completed in a number of the federal court cases and is
      continuing in the remainder. A small number of cases have been transferred
      to the federal courts in which they were filed for further proceedings and
      trial. Judge Bechtle has begun the process of transferring the remaining
      federal court cases to various federal courts throughout the United
      States. As of December 31, 1997, the Federal Judicial Panel on
      Multidistrict Litigation ordered the remand of approximately 210 cases to
      transferor courts for further proceedings. It is not now possible to
      determine when the first federal court cases will be tried.

      STATE COURT LITIGATION

      A number of cases filed in state courts were not eligible for removal and
      transfer into the Multidistrict Litigation. As of December 31, 1997, there
      were approximately 1,800 individual claims pending against the Company in
      several courts around the country, principally in Tennessee, Oklahoma,
      Texas and Pennsylvania. In addition, there were approximately 1,600
      conspiracy claims pending in state courts.

      Approximately 1,550 plaintiffs who had joined together in several
      complaints which had been removed to the Multidistrict Litigation
      proceedings have had their cases remanded to the state court in Memphis,
      Tennessee, where they were originally filed when it was


                                                                              31
<PAGE>   21
         determined that the federal court lacked jurisdiction over their
         claims. The presiding state court judge in Memphis has established a
         case management plan which calls for the preparation of eight
         representative cases for preparation and trial.

         Discovery is proceeding in all remaining state court cases. Some state
         cases have been given trial dates in 1998. It is anticipated that a
         number of other state court cases around the country may be scheduled
         for trial in 1998, although delays in trial dates are common. Trials in
         the Memphis proceedings are scheduled to begin in 1998.

         ACROMED CORPORATION SETTLEMENT

         In December 1996, AcroMed Corporation ("AcroMed"), a spinal implant
         manufacturer and a defendant in many of the cases pending in the
         Multidistrict Litigation, and the Plaintiff's Legal Committee in the
         Multidistrict Litigation announced that they had entered into a
         conditional settlement regarding all product liability claims involving
         the use of AcroMed devices to achieve pedicular fixation with screws in
         spinal fusion surgery. Under the terms of the settlement, AcroMed will
         establish a settlement fund consisting of $100 million in cash plus the
         proceeds of its product liability insurance policies. In January 1997,
         the parties submitted a formal class settlement agreement and related
         documentation for approval by Judge Bechtle. By order dated October 17,
         1997, Judge Bechtle certified the proposed settlement class and
         approved the proposed settlement. All federal and court proceedings
         involving AcroMed devices have been stayed pending final jurisdictional
         consideration of the proposed settlement.

         INSURANCE

         Several insurance carriers have asserted reservation of rights
         concerning the scope and timing of the Company's remaining insurance
         coverage, but have not denied insurance coverage by the Company. Three
         of the carriers, Royal Surplus Lines Insurance Company ("Royal"),
         Steadfast Insurance Company ("Steadfast") and Agricultural Excess and
         Surplus Insurance Company ("Agricultural"), have each filed declaratory
         judgment actions against the Company seeking clarification of their
         rights and obligations, if any, under their respective policies.
         Neither Royal nor Agricultural has paid amounts due to the Company;
         Steadfast has paid only a portion of the amounts due to the Company.
         The Royal and Steadfast lawsuits are pending in the United States
         District Court for the Western District of Tennessee in Memphis. The
         Agricultural lawsuit is pending in the United States District Court for
         the Southern District of Ohio in Cincinnati. The Company believes that
         the receivables are recoverable under the terms of the Royal, Steadfast
         and Agricultural policies. The Company has filed an answer and
         counterclaim in the Royal litigation and a motion seeking the interim
         payment of the Company's defense costs. The Company has filed an answer
         and counterclaim in the Steadfast litigation and intends to file an
         answer and counterclaim in the Agricultural litigation. These
         litigations are in the preliminary stages. The Company believes that
         Royal's, Steadfast's and Agricultural's claims are without merit and
         will defend against them vigorously.


                                                                              32


<PAGE>   22
         As is common in the insurance industry, the Company's insurance
         policies covering product liability claims must be renewed annually.
         Although the Company has been able to obtain insurance relating to
         product liability claims at a cost and on other terms and conditions
         that are acceptable to the Company, there can be no assurance that in
         the future it will be able to do so.

         On January 6, 1997, the Company announced that its 1996 financial
         results would include a pre-tax charge of $50 million relating to costs
         associated with the product liability litigation described above. The
         charge, which is reflected in the Company's 1996 financial statements,
         covers the reasonable foreseeable costs that the Company was positioned
         in late December 1996 to estimate because the litigation had progressed
         and because changes in the fourth quarter of 1996 had occurred in facts
         and circumstances relating to the litigation. Among the changed facts
         and circumstances were the announcement of the AcroMed settlement
         described above, the likelihood that the litigation will continue for
         several years, in part, due to the additional financial resources
         provided to the plaintiff's attorneys as a result of the AcroMed
         settlement, the absence of AcroMed as a member of the joint defense
         group, the status of the Company's insurance described above and the
         continuing absence of dispositive rulings relating to the Company's
         defense motions.

         While it is not possible to accurately predict the outcome of
         litigation, the accrued liability which remained on the Company's
         consolidated balance sheet at December 31, 1997 represents the
         Company's best judgment of the probable reasonable costs (in excess of
         amount of insurance the Company believes are recoverable) to defend and
         conclude the lawsuits based on the facts and circumstances currently
         existing. The costs provided for in the accrued liability include, but
         are not limited to, legal fees paid or anticipated to be paid and other
         costs related to the Company's defense and conclusion of these matters.

         The actual costs to the Company could differ from the estimated charge
         and will be dependent upon a number of factors that will not be known
         for some time, including, among other things, the resolution of defense
         motions and the extent of further discovery. Although an adverse
         resolution of lawsuits could have a material effect on the Company's
         results of operations and cash flows in future periods, the Company
         does not believe that these matters will in the future have a material
         adverse effect on its consolidated financial position. The Company is
         unable to predict the ultimate outcome or the financial impact of the
         product liability litigation.

         SECURITIES LAWS ACTIONS

         Beginning in April 1994, the Company and four of its officers and
         directors were named in five shareholder lawsuits filed in the United
         States District Court in Memphis, Tennessee. Four of the lawsuits
         purported to be class actions. All of the lawsuits were consolidated
         into one case in the United States District Court in Memphis through an
         amended complaint which added four new individual defendants who are
         either current or former directors of the Company. The lawsuit alleges
         that the defendants made false and misleading statements and failed to
         disclose material facts to the investing public and seeks


                                                                              33


<PAGE>   23
         money damages. The alleged securities law violations are based on the
         claim that the defendants failed to disclose that Company sold its
         products illicitly, illegitimately and improperly and to timely
         disclose facts concerning the termination of the former U.S.
         distributor of Sofamor products, National Medical Specialties, Inc.
         ("NMS"). The allegations relating to illicit and illegitimate sales of
         product are, for the most part, copies from product liability
         complaints filed against the Company and other manufacturers currently
         being coordinated in improper sales related to one of the Company's
         selling programs which has been publicly disclosed since May 1991. The
         allegations concerning NMS relate to the termination of the NMS
         distribution agreement covering Sofamor products in the United States.
         On October 3, 1995, the United States District Court Judge in Memphis
         dismissed with prejudice the entire case against the Company and each
         of the individual defendants. The plaintiffs appealed the dismissal to
         the United States Court of Appeals for the Sixth Circuit. On August 14,
         1997, the Court of Appeals affirmed the dismissal of the plaintiffs'
         complaint. The Court of Appeals denied the plaintiffs' request for
         reconsideration on October 9, 1997. On January 6, 1998, the plaintiffs
         filed a petition for certiorari in the United States Supreme Court.

         The Company does not believe the Securities Laws Actions will have a
         material adverse effect on its consolidated financial position, results
         of operations or cash flows because of, among other reasons, the facts
         and circumstances existing with respect to each action, the Company's
         belief that these actions are without merit, certain defenses available
         to the Company and the availability of insurance in the Securities Laws
         Actions.

15.      STOCK OPTION AND RESTRICTED STOCK PLANS

         In 1990, the Company adopted an incentive stock option plan (the "1990
         Plan") for certain key employees covering 1,475,000 shares of common
         stock, a non-qualified stock option plan for distributors and
         consultants (the "Distributor and Consultant Plan") covering 225,000
         shares of common stock, and a restricted stock plan covering 148,450
         shares of common stock. The number of shares covered under the 1990
         Plan was subsequently reduced to 675,000 on June 21, 1993. During 1996,
         the Board of Directors proposed an amendment to the 1990 Plan to
         decrease the number of shares of the common stock available under the
         Plan by 61,642.

         Under the Distributor and Consultant Plan, the exercise price may not
         be less than $2.22 per share. Options have a maximum term of ten years
         from the date of the option grant. During 1995, the number of shares of
         common stock covered was increased to 625,000.

         In February 1991, the Company adopted a stock option plan for certain
         directors of the Company ("Directors' Plan").

         In December 1992, the Company adopted the 1993 long-term incentive plan
         (the "Long-Term Incentive Plan") for certain directors and key
         employees covering 500,000 shares of common stock. The number of shares
         of common stock reserved under the Long-Term Incentive Plan was
         increased to 800,000 in 1993, to 2,500,000 in 1994, to 3,500,000 in


                                                                              34

         1995 and to 6,000,000 in 1997. Awards may be in the form of stock
         options to purchase shares, stock appreciation rights, performance
         units, restricted stock or any combination of the above. Options have a
         maximum term of ten years from the date of the option grant. Under the
         Long-Term Incentive Plan, the exercise price shall be determined by the
         Company, except that the exercise price may not be less than the market
         price at the date of the option grant for any incentive stock options
         awarded.

         During 1997, the Board of Directors proposed an amendment to the
         Company's Long-Term Incentive Plan to increase the number of shares of
         the common stock available under the Plan by 1,500,000, contingent upon
         approval by the Company's shareholders.

         Activity under all of the stock option plans, including the 1,500,000
         shares of common stock approved by the Board of Directors in 1997, for
         the years ended December 31, 1997, 1996, and 1995 is summarized as
         follows:

         The Company applies APB Opinion No. 25 and related Interpretations in
         accounting for its plans. During 1995, the Financial Accounting
         Standards Board issued Statement No. 123, "Accounting for Stock-Based
         Compensation" ("FAS 123") changing the methods for recognition of cost
         on plans similar to those of the Company. Adoption of the accounting
         provisions of FAS 123 is optional; however, proforma disclosures as if
         the Company adopted the cost recognition requirements under FAS 123 is
         presented below:

         The fair value of each option grant is estimated on the date of grant
         using the Black-Scholes option-pricing model with the following
         weighted average assumptions used for grants in 1997: dividend yield of
         0%, expected volatility of 40.0%, risk-free interest rate of 6.1%, and
         expected lives of 5.0 years; 1996: dividend yield of 0%, expected
         volatility of 44.4%, risk-free interest rate of 6.2%, and expected
         lives of 4.2 years, 1995: dividend yield of 0%, expected volatility of
         44.4%, risk-free interest rate of 6.3%, and expected lives of 4.2
         years. The weighted average fair value of options at grant date were
         $19.65, $12.59 and $8.20 in 1997, 1996 and 1995, respectively.

         The effects of applying FAS 123 in this proforma disclosure are not
         indicative of future amounts.

         FAS 123 does not apply to awards prior to 1995, and additional awards
         in future years are anticipated.

16.      NET INCOME PER COMMON SHARE

         In February 1997, the Financial Accounting Standards Board issued
         Statement No. 128 ("FAS 128"). This statement establishes standards for
         computing and presenting earnings per share ("EPS"). Basic EPS excludes
         dilution and is computed by dividing income available to common
         stockholders by the weighted-average number of common shares
         outstanding for the period. Diluted EPS reflects the potential dilution
         that could occur if securities or other contracts to issue common stock
         were exercised or converted into common stock or resulted in the
         issuance of common stock that then shared in the earnings of the
         entity. FAS 128 requires restatement of all prior-period EPS data
         presented.

         Potential common stock is in the form of stock options which have an
         effect on 1997, 1996 and 1995 diluted net income per common share
         calculations. Potential common stock also includes assumed converted
         debt securities. For the years ended December 31, 1997, 1996 and 1995,
         net income was adjusted by $125, $124 and $115, respectively, to
         calculate EPS.


                                                                              36


<PAGE>   26

         This adjustment represented the interest charges, net of taxes, from
         convertible debt which was assumed to be converted for the weighted
         average number of shares calculation. The following table presents
         information necessary to calculate diluted EPS for the years ended
         December 31, 1997, 1996 and 1995:

18.      EMPLOYEE BENEFIT PLANS

         In January 1990, the Company adopted an employee savings plan under
         Section 401(k) of the Internal Revenue Code. This plan covers all
         full-time employees that are 21 years of age and have completed at
         least six months of continuous service with the Company. In 1995, the
         Company increased its maximum matching contribution to equal 100% of
         the employee's first 3% contributed and 50% of the next 2%. These
         matching percentages are subject to revision at the discretion of the
         Company's Board of Directors. Company contributions generally vest at
         20% per year beginning the end of the second year of service with the
         participants becoming fully vested in the sixth year of service. The
         amounts charged against income in 1997, 1996, and 1995 were $800, $477
         and $385, respectively.

         In November 1991, the Company adopted an employee stock purchase plan
         ("ESPP") to provide employees the opportunity to purchase shares of
         common stock of the Company. The ESPP covers full-time employees (as
         defined by the ESPP) that have completed 6 months of employment. An
         aggregate of 60,000 of the Company's shares of common stock have been
         reserved for inclusion in the ESPP. The amount charged against income
         in 1997, 1996 and 1995 was $33, $22 and $14, respectively, which
         represented the Company's match of 15% of the employee's contribution.


                                                                              38

         The carrying amounts for cash, short-term investments, notes and other
         receivables, and notes and loans payable approximate fair value due to
         the short maturity of these instruments.

         The fair value of long-term debt is estimated based on current rates
         available to the Company for debt with similar remaining maturities or
         quoted market prices for the shares of stock to which the debt
         instrument may be converted, as applicable.

         The estimated fair value of the Company's financial instruments at
         December 31, 1997 and 1996 are as follows:

20.      SUBSEQUENT EVENTS

         On January 26, 1998, the Company purchased Sofyc, S.A. ("Sofyc") for an
         aggregate of 2,806,080 privately placed shares of the Company's common
         stock, $1,000 in cash (less certain expenses relating to the
         repurchase), and the Company's agreement to repay certain outstanding
         loans of Sofyc equal to approximately $925. Sofyc is the personal
         holding company of the Cotrel family and owner of approximately 14% or
         3,337,272 shares of the Company's common stock. As a result of the
         purchase of SOFYC, the outstanding shares of common stock of the
         Company will be reduced by 531,192 shares. In accordance with the
         purchase agreement, the Company filed a registration statement with the
         Securities and Exchange Commission relating to a proposed public
         offering of 1,600,000 shares of the common stock owned by the Cotrel
         family. The registration statement also includes a proposed public
         offering of up to 1,125,000 newly issued shares of common stock to be
         sold by the Company and 75,000 shares to be sold by a director of the
         Company. In addition, Sofamor Danek will grant to the underwriters an
         over-allotment option relating to a maximum of 420,000 shares of common
         stock. The Company expects to incur a foreign tax liability of
         approximately $10,500 in connection with exchange of the Sofyc shares
         which will result in an adjustment to equity by such amount.
