     -   In 1997 and 1996, net income tax benefits of $3,470 and $2,115,
         respectively, were realized by the Company as a result of certain
         common stock options being exercised and vesting of certain
         restricted common stock, reducing accrued federal and state income
         taxes payable and increasing common stock.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                 (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)


1.    Financial Statement Presentation

      The consolidated balance sheet as of June 30, 1997, the consolidated
      statements of income for the three and six months ended June 30, 1997 and
      1996, and the consolidated statements of cash flows for the six months
      ended June 30, 1997 and 1996, are unaudited but, in the opinion of
      management, include all adjustments (consisting only of normal recurring
      adjustments) necessary for a fair presentation of financial position,
      results of operations and cash flows. Accordingly, certain information and
      footnote disclosures normally included in complete financial statements
      prepared in accordance with generally accepted accounting principles have
      been condensed or omitted. It is suggested that these consolidated
      financial statements be read in conjunction with the financial statements
      and notes thereto included in the Company's 1996 Annual Report on Form
      10-K.

3.    Income Taxes

      The Company's effective income tax rate was 29.0% for the quarter and six
      months ended June 30, 1997. The effective rates were 29.4% and 27.4% for
      the quarter and six months ended June 30, 1996, respectively. The
      difference between the Company's effective and statutory tax rates for
      both the quarter and six months ended June 30, 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. ("Sofamor"), and the subsequent reorganization of Sofamor
      from a Societe Anonyme (S.A.) under French law to a Societe en Nom 
      Collectif (S.N.C.) in late 1993. At June 30, 1997, the balance sheet of 
      the Company reflected a net deferred tax asset of $36,766. No valuation
      allowance was recorded since sufficient taxable income existed in
      available carryback periods to recognize fully these net deferred tax 
      assets.




                                       7

<PAGE>   8

      During the first six months of 1997 and 1996, charges in lieu of income
      taxes of $3,470 and $2,115 respectively, were recorded by the Company as
      a result of certain common stock options being exercised and vesting of
      certain restricted common stock.

4.    Adoption of SFAS 128

      In March 1997, the Financial Accounting Standards Board (the "Board")
      issued Statement No. 128 "Earnings Per Share" ("FAS 128"). FAS 128
      establishes standards for computing and presenting earnings per share
      ("EPS") and replaces the presentation of primary EPS with a presentation
      of basic EPS. It also requires dual presentation of basic and diluted EPS
      on the face of the statement of operations and requires a reconciliation
      of the numerator and the denominator of the basic EPS computation to the
      numerator and the denominator of the diluted EPS computation. The Company
      will adopt the disclosure requirements of FAS 128 beginning December 31,
      1997. The Company does not expect the adoption of FAS 128 to have a
      material impact on earnings per share when presented on a comparable
      basis.

5.    Commitments and Contingencies

      The Company is involved from time to time in litigation on various matters
      which are routine to the conduct of its 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. Although the plaintiffs have advanced claims under
      many different legal theories, the essence of their claims appear 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 Food & Drug Administration ("FDA") rules and regulations (governing
      marketing and labeling), 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. 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 




                                       8

<PAGE>   9

      unspecified amounts. Many of the plaintiffs only allege as monetary
      damages 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.

      To date, approximately two thousand eight hundred (2,800) plaintiffs have
      joined in lawsuits against the Company. The majority of these plaintiffs
      filed their claims in 1995. The Company is also named as a defendant in
      lawsuits involving about two thousand six hundred (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 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 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 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. Currently, the Company is a defendant in approximately one
      thousand (1,000) individual claims and one thousand (1,000) conspiracy
      claims consolidated in the Multidistrict Litigation. On August 22, 1996,
      Judge Bechtle dismissed without prejudice plaintiffs' conspiracy claims.
      Most plaintiffs asserting conspiracy claims in the Multidistrict
      Litigation have filed amended or new complaints. It is not possible to
      determine at this time precisely how many of these conspiracy complaints
      will be reasserted or the number of additional plaintiffs that may file
      new lawsuits. 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. It is anticipated that the first cases to be
      returned for trial to the federal court in which they were filed will be
      remanded beginning in August 1997. 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. Currently, there are
      approximately one thousand eight hundred (1,800) individual claims pending
      against the Company in several courts around the country, principally in
      Tennessee, Oklahoma, Texas and Pennsylvania. In addition, there are
      approximately one thousand six hundred (1,600) conspiracy claims pending
      in state courts.

      Approximately one thousand five hundred fifty (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 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 pretrial preparation and trial.

      Discovery is proceeding in all remaining state court cases. Some state
      cases have been given trial dates in 1997. It is anticipated that a number
      of other state court cases around the country may be scheduled for trial
      in 1997, although delays in trial dates are common. Trials in the Memphis
      proceedings are scheduled to commence in January of 1998.

      ACROMED CORPORATION PROPOSED 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 proposed 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. Judge Bechtle is currently
      considering whether to certify the proposed settlement class and the
      fairness, adequacy and reasonableness of the proposed settlement. All
      federal court proceedings involving AcroMed devices have been stayed
      pending final consideration of the proposed settlement.

      INSURANCE

      All of the insurance carriers for policy periods in which these claims
      have been made have asserted reservation of rights, but have not denied
      coverage to the Company. To date, the cost of defending these claims has
      been reimbursed by certain of the primary and excess carriers, and the
      Company is actively engaged in discussions concerning the recovery of
      amounts currently due and owing from all other carriers. The Company
      believes that these receivables are recoverable under the terms of the
      Company's policies. The Company's insurance policies are reduced by the
      costs of defense, except for a policy issued by Royal Surplus Lines
      Insurance Co. ("Royal") covering the 12-month period that began in
      November 1995. The Company estimates that the litigation may continue for
      several years and, if so, the cost to defend and conclude these lawsuits
      is likely to exhaust its insurance 



                                       10

<PAGE>   11

      coverage. Royal brought an action in December 1996 in the Federal District
      Court for the Middle District of Tennessee (Nashville Division) seeking a
      declaratory judgment as to, among other things, whether the policy covers
      lawsuits which have been reported to the insurer during the policy period.
      The Company has filed its answer and counterclaim in the Royal lawsuit. In
      addition, the Company has initiated its own declaratory judgment lawsuit
      against Royal in the Federal District Court located in Memphis, Tennessee.
      This lawsuit seeks a declaration of coverage and immediate payment of the
      outstanding balance of amounts due from Royal. Based on the Company's
      motion, Royal's lawsuit has been transferred to the Federal District Court
      in Memphis Tennessee. This litigation is in the preliminary stages. The
      Company believes that Royal's claims are without merit and will defend 
      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 coverage 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.

      The Company's 1996 financial results reflect a pre-tax charge relating to
      costs associated with the product liability litigation described above.
      The costs provided for 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 the
      lawsuits could have a material effect on the Company's results of
      operations 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 purport
      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 the Company sold its products
      illicitly, illegitimately and improperly and to timely disclose facts
      concerning the termination of the former United States distributor of
      Sofamor products, National Medical Specialties, Inc. ("NMS"). The
      allegations relating to illicit and illegitimate sales of product are, for
      the most part, copied from product liability complaints filed against the
      Company and other manufacturers currently being coordinated in the





                                       11


<PAGE>   12

      United States District Court for the Eastern District of Pennsylvania 
      which are referred to above. The allegations of improper sales relate 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 have appealed the
      dismissal to the United States Court of Appeals for the Sixth Circuit,
      which has not yet ruled on this appeal.

      SPANISH DISTRIBUTOR ACTION

      In late September 1994, a Magistrate of the Commercial Court in Paris
      ruled in favor of a former Spanish distributor of Sofamor's products on a
      claim of wrongful termination of the distribution agreement in 1992. Prior
      to June 1993, an accrual was established, with a related charge to
      earnings, for this pending litigation. In June 1993, the Company also
      established a separate indemnity with respect to potential losses
      resulting from such lawsuit and placed in escrow shares issued to the
      former Sofamor shareholders pending the final outcome of this lawsuit. The
      $3.0 million award (including interest) rendered by the French Magistrate
      exceeded the pre-established accrual. As a result, the Company recorded an
      expense of $2.2 million for the non-recurring litigation award during the
      third and fourth quarters of 1994. The Company filed an appeal which
      involves a complete retrial on all issues. The former Spanish distributor
      has filed its papers in the appeal and seeks additional damages; the
      Company seeks to have the decision of the Commercial Court reversed. A
      hearing on the appeal is currently scheduled for the fourth quarter of
      1997.

      The Company does not believe the Securities Laws Actions or the Spanish
      Distributor Action, described above, 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.

RESULTS OF OPERATIONS*

The Company reported record revenues of $73.6 million and $143.4 million for the
quarter and six months ended June 30, 1997. Second quarter 1997 revenues
increased $16.8 million or 29.6%, compared with the second quarter of 1996. An
increase in volume contributed revenue growth of 28.0%. The Company's conversion
of certain portions of its international distribution network to direct sales,
which resulted in higher selling prices, contributed a 1.7% increase. Other net
pricing changes in existing distribution channels resulted in a 3.5% increase in
revenues. If exchange rates had been constant, revenues would have reflected an
additional 3.6% increase compared with the second quarter of 1996.

* Except for the historical information contained in this Quarterly Report on
Form 10-Q, the matters discussed herein (including, in particular, those
discussed in Part II, Item 1, "Legal Proceedings") are forward-looking
statements that involve risks and uncertainties, including (without limitation)
the timely development and acceptance of new products, the impact of competitive
products, the timely receipt of regulatory clearances required for new products,
the regulation of the Company's products generally, the disposition of certain
litigation involving the Company and certain other risks and uncertainties
detailed from time to time in the Company's periodic reports (including the
Annual Report on Form 10-K for the year ended December 31, 1996) filed with the
Securities and Exchange Commission and "Factors That May Affect Future Operating
Results and Financial Condition" detailed in this Quarterly Report on Form 10-Q
for the quarter ended June 30, 1997.




                                       13
<PAGE>   14


Revenues for the six months ended June 30, 1997, represented a $32.3 million or
29.1% increase over the same period in 1996. Higher volume generated 27.3%
revenue growth. The Company's conversion of certain portions of its
international distribution network to direct sales, which resulted in higher
selling prices, contributed a 2.1% increase. Other net pricing changes in
existing distribution channels resulted in a 3.1% increase in revenues. If
exchange rates had been constant, revenues would have reflected an additional
3.4% increase compared with the first six months of 1996.

U.S. revenues increased 30.9% to $48.9 million and 32.9% to $97.2 million during
the quarter and six months ended June 30, 1997, respectively, from the same
periods in 1996. The Company believes the improvement in U.S. revenues is
primarily the result of the increasing number of instrumented spinal fusions, as
well as the acceptance of new products and services such as the
STEALTHSTATION(TM) system, the MEDNEXT(R) surgical drill system, and service
fees related to cortical bone dowel and other allograft bone products.

Non-U.S. revenues advanced 27.1% to $24.7 million and 21.8% to $46.2 million
during second quarter and first six months of 1997, respectively, from the same
periods in 1996. If exchange rates had been constant, the revenue increases for
the second quarter and first six months of 1997 over the comparative periods in
1996 would have been 38.1% and 32.1%, respectively. Higher sales volume in core
products and the acceptance of new products were the primary sources of the
increases in revenues for the quarter and six months ended June 30, 1997,
compared with the same periods in 1996. In addition, the Company's revenues
continued to benefit from the direct sales operations which were established in
selected countries during 1996 and the first half of 1997.

The Company's second quarter 1997 gross margin of 82.8% remained relatively
constant with the second quarter 1996 gross margin of 82.9%. Gross margin during
the first six months of 1997 improved to 82.5% from 81.7% during the same period
in 1996. The slight improvement in gross margin during the first six months of
1997 was due to leveraging of manufacturing costs over greater unit volume and
higher selling prices related to changes in international distribution.

Selling, general, and administrative ("SG&A") expenses expressed as a percentage
of revenues decreased to 47.0% in the second quarter of 1997, compared with
47.2% during the same period in 1996. SG&A expenses for the first six months of
1997 were 47.0% of revenues, down from 47.6%, during the first six months of
1996. The decreases 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 the first half of 1997.

Research and development ("R&D") expenses totaled $4.8 million, or 6.5% of
revenues, for the second quarter of 1997, compared with $3.9 million, or 6.9% of
revenues, for the second quarter of 1996. For the first six months of 1997, R&D
expenses were $9.5 million or 6.5% of revenues compared to 6.8% of revenues for
the same period in 1996. In dollars, R&D spending increased 21.6% and 25.7% for
the quarter and six months ended June 30, 1997, respectively, over the same
periods in 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 



                                       14

<PAGE>   15

related to frameless stereotactic surgery in the spinal and neurological fields
of use. These expenditures demonstrate the Company's continued commitment to the
pursuit of applying new medical technologies to product opportunities.

Interest expense for the quarter and six months ended June 30, 1997, was $1.5
million and $2.7 million, respectively, compared with $795,000 and $1.6 million,
respectively, for the same periods in 1996. Interest expense was higher during
the quarter and six months ended June 30, 1997, compared with the same periods
in the prior year due to interest on increased borrowings against the Company's
credit facilities occurring principally as a result of acquisitions made in
1996.

The Company's effective income tax rate was 29.0% for the quarter and six months
ended June 30, 1997. The effective rates for the second quarter and first six
months of 1996 were 29.4% and 27.4%, respectively. The difference between the
Company's effective and statutory tax rates for both the quarter and six months
ended June 30, 1997 and 1996, resulted primarily from the impact of certain
elections made for U.S. tax purposes following the combination of Danek Group,
Inc. with Sofamor S.A. ("Sofamor"), and the subsequent reorganization of Sofamor
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 among other factors. Higher future pre-tax income could lead to
higher future effective tax rates. At June 30, 1997, the balance sheet of the
Company reflected a net deferred tax asset of $36.8 million. No valuation
allowance was recorded since sufficient taxable income exists in available
carryback periods to recognize fully these net deferred tax assets.

In June 1997, the Financial Accounting Standards Board issued Statement No. 128
"Earnings Per Share" ("FAS 128"). FAS 128 establishes standards for computing
and presenting earnings per share ("EPS") and replaces the presentation of
primary EPS with a presentation of basic EPS. It also requires dual presentation
of basic and diluted EPS on the face of the statement of operations and requires
a reconciliation of the numerator and the denominator of the basic EPS
computation to the numerator and the denominator of the diluted EPS computation.
The Company will adopt the disclosure requirements of FAS 128 beginning December
31, 1997. The Company does not expect the adoption of FAS 128 to have a material
impact on earnings per share when presented on a comparable basis.


LIQUIDITY AND CAPITAL RESOURCES

Cash generated from operations and the Company's revolving lines of credit are
the principal 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 will be sufficient to meet its expected cash needs
for the foreseeable future. Cash, cash equivalents and short-term investments
totaled $2.7 million at June 30, 1997, compared with $2.9 million at December
31, 1996.




                                       15

<PAGE>   16

The Company's working capital increased by $19.6 million during the first six
months of 1997. The increase in working capital resulted primarily from
operations. Accounts receivable increased $6.3 million from December 31, 1996,
due principally to the increase in revenues. Inventories and loaner set
inventories increased by $21.4 million from year-end, 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 expenses incurred in connection with product liability
litigation, increased $6.3 million from the previous year-end.

In 1995, the Company entered into to a license agreement (the "Agreement") with
Genetics Institute which resulted in a special charge of $45.3 million. The
Company made payments in June 1997 and 1996 of $17.5 million and $12.5 million,
respectively, as required by the Agreement. The final scheduled payment of $7.5
million is payable on June 30, 1998. All payments include both principal and
imputed interest.

The purchase agreements for two of the 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 will be reflected as
purchase price adjustments. During 1996, the Company recorded an adjustment to
the purchase price of one of these acquisitions of $4.2 million. This amount was
paid during April of 1997. The Company is unable to determine whether such
payments will be required for the years 1997 through 1999.

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. At June 30, 1997,
the balance sheet of the Company reflected a long-term liability of $45.4
million and the current portion of this liability was included in accrued
expenses. (See Part II, Item 1.)

Additions to property, plant and equipment during the first six months of 1997
of $4.4 million were related to capital asset 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 a new
facility adjacent to its existing headquarters. This lease will be accounted for
under Statement of Financial Accounting Standards No. 13, "Accounting for
Leases," as an operating lease.

The Company has committed lines of credit totaling $95.9 million. At June 30,
1997, $85.4 million was outstanding under these committed lines of credit and
other short-term borrowings. The committed lines of credit consist primarily of
a $80.0 million uncollateralized revolving line of credit with a U.S. bank which
matures in July 2000.

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.

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:

Regulatory Clearances. The Company manufactures devices that are subject to the
regulations of the FDA and, in some cases, to the regulations of foreign
governmental authorities. In particular, such devices are subject to marketing
clearance by the FDA before sales can be made in the United States. 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 FDA review will not involve delays adversely
affecting the marketing and sale of new products and devices by the Company. The
enforcement of FDA regulations depends 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 cannot predict the extent or impact of future
foreign, federal, state or local legislation or regulation.

Potential Impact of Health Care Cost Containment Proposals on Profitability. In
recent years, the cost of health care 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 what changes will be made in the reimbursement
methods utilized by third-party health care payers. In addition, hospitals and
other health care providers have become increasingly cost sensitive. To date,
the Company does not believe that such health care 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.

Product Obsolescence. Spinal implant and other devices are subject to continuous
improvements and modifications and typically are rendered obsolete within a few
years. Success, therefore, requires any medical device company to devote
substantial resources to continued product development. The Company maintains
active research and development programs and has been successful in developing
or acquiring new products in the past. There can be no assurance that the
Company will be able to develop and introduce or acquire new products that will
enable it to remain competitive in the future.

Product Liability; Insurance. In recent years, physicians, hospitals, and other
participants in the health care industry have become subject to an increasing
number of lawsuits alleging malpractice, product liability or asserting related
legal theories, many of which involve large claims and significant defense
costs. The Company currently maintains liability insurance intended to cover
such claims, although 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. The Company is currently involved in product
liability litigation. (See Note 5 to the Consolidated Financial Statements.)




                                       17

<PAGE>   18

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.

Competition. Worldwide, there are a number of firms producing spinal implant
devices. The Company currently competes with a number of firms with financial,
marketing and technical resources comparable to or greater than those of the
Company. Because of the growth of the number of spinal fusion procedures
performed in recent years, a number of companies, including those active in
producing various orthopaedic and neurological products and having financial,
marketing and technical resources significantly greater than those of the
Company, have begun producing spinal implant devices. The Company anticipates
that additional companies may also begin such production.

Retention of Personnel. The Company is highly dependent upon its senior
management, and the competition for qualified management personnel is intense.
The loss of key personnel or an inability to attract, retain and motivate such
persons could adversely affect the business and prospects of the Company. There
can be no assurance that the Company will be able to retain its existing senior
management personnel or to attract additional qualified personnel if needed. The
Company also depends on its contractual relationships with certain physicians
for product ideas, research and advice. There can be no assurance that the
Company will be able to maintain and develop such relationships.

Global Market Risks. 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 foreign
markets in which the Company distributes its products.

Intellectual Property. The Company is dependent on its proprietary intellectual
property and attempts to protect such intellectual property through patents,
licensing, trade secrets and proprietary know-how. In the medical device
industry, challenges by third parties regarding intellectual property rights
occur frequently. Such challenges may result in litigation which is often
complex and expensive. There can be no assurance that the Company's proprietary
rights will not be challenged, rendered unenforceable or circumvented and that
pending or future patent or trademark applications will be granted.

                          PART II -- OTHER INFORMATION


Item 1.   LEGAL PROCEEDINGS

The Company is involved from time to time in litigation on various matters which
are routine to the conduct of its 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. Although the plaintiffs have advanced claims under many different legal
theories, the essence of their claims appear 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 Food & Drug Administration ("FDA") rules
and regulations (governing marketing and labeling), 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. 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 damages 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.

To date, approximately two thousand eight hundred (2,800) plaintiffs have joined
in lawsuits against the Company. The majority of these plaintiffs filed their
claims in 1995. The Company is also named as a defendant in lawsuits involving
about two thousand six hundred (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 Company has asserted
and will continue to assert these defenses primarily through the filing of
dispositive 




                                       19

<PAGE>   20

motions. The Company believes that all product liability lawsuits currently
pending against it are without merit and will continue to defend 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 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.
Currently, the Company is a defendant in approximately one thousand (1,000)
individual claims and one thousand (1,000) conspiracy claims consolidated in the
Multidistrict Litigation. On August 22, 1996, Judge Bechtle dismissed without
prejudice plaintiffs' conspiracy claims. Most plaintiffs asserting conspiracy
claims in the Multidistrict Litigation have filed amended or new complaints. It
is not possible to determine at this time precisely how many of these conspiracy
complaints will be reasserted or the number of additional plaintiffs that may
file new lawsuits. 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. It is anticipated that the first cases to be
returned for trial to the federal court in which they were filed will be
remanded beginning in August 1997. 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. Currently, there are approximately
one thousand eight hundred (1,800) individual claims pending against the Company
in several courts around the country, principally in Tennessee, Oklahoma, Texas
and Pennsylvania. In addition, there are approximately one thousand six hundred
(1,600) conspiracy claims pending in state courts.

Approximately one thousand five hundred fifty (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 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 pretrial preparation and
trial.





                                       20

<PAGE>   21

Discovery is proceeding in all remaining state court cases. Some state cases
have been given trial dates in 1997. It is anticipated that a number of other
state court cases around the country may be scheduled for trial in 1997,
although delays in trial dates are common. Trials in the Memphis proceedings are
scheduled to commence in January of 1998.

ACROMED CORPORATION PROPOSED 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 proposed
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. Judge Bechtle is currently
considering whether to certify the proposed settlement class and the fairness,
adequacy and reasonableness of the proposed settlement. All federal court
proceedings involving AcroMed devices have been stayed pending final
consideration of the proposed settlement.

INSURANCE

All of the insurance carriers for policy periods in which these claims have been
made have asserted reservation of rights, but have not denied coverage to the
Company. To date, the cost of defending these claims has been reimbursed by
certain of the primary and excess carriers, and the Company is actively engaged
in discussions concerning the recovery of amounts currently due and owing from
all other carriers. The Company believes that these receivables are recoverable
under the terms of the Company's policies. The Company's insurance policies are
reduced by the costs of defense, except for a policy issued by Royal Surplus
Lines Insurance Co. ("Royal") covering the 12-month period that began in
November 1995. The Company estimates that the litigation may continue for
several years and, if so, the cost to defend and conclude these lawsuits is
likely to exhaust its insurance coverage. Royal brought an action in December
1996 in the Federal District Court for the Middle District of Tennessee
(Nashville Division) seeking a declaratory judgment as to, among other things,
whether the policy covers lawsuits which have been reported to the insurer
during the policy period. The Company has filed its answer and counterclaim in
the Royal lawsuit. In addition, the Company has initiated its own declaratory
judgment lawsuit against Royal in the Federal District Court located in Memphis,
Tennessee. This lawsuit seeks a declaration of coverage and immediate payment of
the outstanding balance of amounts due from Royal. Based on the Company's
motion, Royal's lawsuit has been transferred to the Federal District Court in
Memphis Tennessee. This litigation is in the preliminary stages. The Company
believes that Royal's claims are without merit and will defend 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 coverage relating to product liability claims
at a cost and on other terms and conditions 




                                       21

<PAGE>   22

that are acceptable to the Company, there can be no assurance that in the future
it will be able to do so.

The Company's 1996 financial results reflect a pre-tax charge relating to costs
associated with the product liability litigation described above. The costs
provided for 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 the lawsuits could have
a material effect on the Company's results of operations 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 purport 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 the Company sold its products illicitly, illegitimately and
improperly and to timely disclose facts concerning the termination of the former
United States distributor of Sofamor products, National Medical Specialties,
Inc. ("NMS"). The allegations relating to illicit and illegitimate sales of
product are, for the most part, copied from product liability complaints filed
against the Company and other manufacturers currently being coordinated in the
United States District Court for the Eastern District of Pennsylvania which are
referred to above. The allegations of improper sales relate 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 have appealed the dismissal to the United States Court of Appeals for
the Sixth Circuit, which has not yet ruled on this appeal.

SPANISH DISTRIBUTOR ACTION

In late September 1994, a Magistrate of the Commercial Court in Paris ruled in
favor of a former Spanish distributor of Sofamor's products on a claim of
wrongful termination of the distribution agreement in 1992. Prior to June 1993,
an accrual was established, with a related charge to earnings, for this pending
litigation. In June 1993, the Company also established a separate indemnity with
respect to potential losses resulting from such lawsuit and placed in escrow
shares issued to the former Sofamor shareholders pending the final outcome of
this lawsuit. The 





                                       22

<PAGE>   23

$3.0 million award (including interest) rendered by the French Magistrate
exceeded the pre-established accrual. As a result, the Company recorded an
expense of $2.2 million for the non-recurring litigation award during the third
and fourth quarters of 1994. The Company filed an appeal which involves a
complete retrial on all issues. The former Spanish distributor has filed its
papers in the appeal and seeks additional damages; the Company seeks to have the
decision of the Commercial Court reversed. A hearing on the appeal is currently
scheduled for the fourth quarter of 1997.

The Company does not believe the Securities Laws Actions or the Spanish
Distributor Action, described above, 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.

Operations and Financial Condition--Factors That May Affect Future Operating
Results and Financial Condition--Product Liability; Insurance and Intellectual
Property."

     Section 2.02 Letters of Credit Subcommitment.

          (a) Provided no Event of Default or Default Condition exists, and
     subject to the terms and conditions of the Loan Documents, the Lenders have
     agreed that the Agent on behalf of the Lenders will issue to third party
     beneficiaries for the account of Borrower, or jointly for the account of
     Borrower and a Subsidiary of Borrower, irrevocable standby letters of
     credit ("Letters of Credit") in the face amount of up to $5,000,000 in the

     Letters of Credit in an aggregate face amount exceeding $5,000,000. In
     connection with the issuance of each Letter of Credit, the Borrower shall
     complete a Letter of Credit Application Agreement, and such other
     documentation in form and substance as required by Agent. The term of any
     Letter of Credit shall not extend beyond the Maturity Date.

          (b) In connection with the issuance of any Letter of Credit, the
     Borrower shall pay in advance to Agent a Letter of Credit Fee (calculated
     as of the date of the issuance of the 



                                      -14-

<PAGE>   20

     Letter of Credit and accruing to the end of the current Fiscal Quarter, and
     thereafter payable quarterly in advance for the actual number of days in
     such Fiscal Quarter, calculated on a 360-day year, provided however that if
     the term of the Letter of Credit expires before the end of the Fiscal
     Quarter, then it will be payable for the actual number of days until
     expiration) to be apportioned and paid by Agent to each of the Lenders
     pursuant to the Pro Rata Share of each Lender. If the term of any Letter of
     Credit is less than one (1) month, the Letter of Credit Fee shall be
     calculated as if the term of the Letter of Credit were equal to one (1)
     month.

          (c) In connection with the issuance of any Letter of Credit, the
     Borrower shall also pay to Agent a Facing Fee (payable on the dates set
     forth in subsection (b) of this Section) calculated on a 360 day year. None
     of the Lenders, except for the Agent, shall share in the Facing Fee.

          (d) The Agent agrees to use its best efforts to issue and deliver to
     the Borrower each requested Letter of Credit within three (3) Business Days
     following submission by Borrower of a properly completed Letter of Credit

     the Maturity Date. The language of each Letter of Credit, including the
     requirements for a draw thereunder, shall be subject to the reasonable
     approval of the Agent.

          (f) The face amount of all outstanding Letters of Credit shall reduce
     the Borrower's ability to receive Advances under the Revolving Credit Loan
     by such amount. Additionally, any payment by Agent under a Letter of Credit
     shall be treated as an Advance under the Revolving Credit Loan, and the
     terms and provisions of repayment shall be treated as an Advance under the
     Revolving Credit Loan.

          (g) The Lenders shall participate in all Letters of Credit requested
     by the Borrower under this Agreement except for the Facing Fee. Each Lender
     holding a Revolving Credit Note, upon issuance of a Letter of Credit by the
     Agent, shall be promptly notified by the Agent and shall be deemed to have
     purchased without recourse, a risk participation from the Agent in such
     Letter of Credit and the obligations arising thereunder, in each case in an
     amount equal to its Pro Rata Share of all obligations under such Letter of
     Credit and shall absolutely, unconditionally, and irrevocably assume, as
     primary obligor and not as surety, and be obligated to pay to the Agent
     therefor and discharge when due, its Pro Rata Share of all obligations
     arising under such Letter of Credit. Without limiting the scope and nature
     of a Lender's participation in any Letter of Credit, to the extent that the
     Agent has not been reimbursed as required hereunder or under any such
     Letter of Credit, each such Lender shall pay to the Agent its Pro Rata
     Share of such unreimbursed drawing in same day funds on the day of
     notification by the Agent of an unreimbursed drawing. The obligation of
     each Lender to so reimburse the Agent shall be absolute and unconditional
     and shall not be affected by the occurrence of a Default Condition or an
     Event of Default or any other occurrence or event.

     Section 2.03 Swing Line Loan.

          (a) Swing Line Subcommitment. Subject to and upon the terms and
     conditions herein set forth, the Swing Line Lender establishes in favor of
     the Borrower, its Swing Line Subcommitment. The Swing Line Lender, subject
     to and upon the terms and conditions set forth herein, from time to time,
     agrees to make to the Borrower Advances under the Swing Line Loan in an
     aggregate principal amount outstanding at any time not to exceed the Swing
     Line Subcommitment. Borrower shall be entitled to borrow, repay and
     reborrow Advances under the Swing Line Loan in accordance with the
     provisions hereof and of the Swing Line Note.

          (b) Amount and Terms of Swing Line Loan. Each Advance under the Swing
     Line Loan shall be made from the Swing Line Lender at the Swing Line Rate
     in accordance with the borrowing procedure specified in Section 2.05.

          (c) Repayment of Swing Line Loan by Revolving Credit Loan. If (i)
     after giving effect to any request for an Advance, the aggregate principal
     amount of (A) the portion of the Revolving Credit Loan (including the face
     amount of all outstanding Letters of Credit), held by Swing Line Lender as
     a Lender under the Revolving Credit Loan, plus (B) the Swing Line Loan
     would exceed the maximum amount of the Revolving Credit Note held by the
     Swing Line Lender, or (ii) there are any outstanding Advances under the
     Swing Line Loan upon the occurrence of an Event of Default, then each
     Lender holding a Revolving Credit Note hereby agrees, upon the request of
     the Swing Line Lender, to make an Advance under the Revolving Credit Loan
     in an amount equal to such Lender's Pro Rata Share of the outstanding
     principal amount of the Swing Line Loan (the "Refundable Swing Line Loan")
     outstanding on the date such notice is given. On or before 11:00 a.m.
     (Nashville, Tennessee time) on the first Business Day following receipt by
     such Lender of a request to make the Advances referenced in the preceding
     sentence, each such Lender (other than the Swing Line Lender) shall deposit
     in an account specified by the Agent to the Lenders from time to time the
     amount as requested in same day funds, whereupon such funds shall be
     immediately delivered to the Swing Line Lender (and not the Borrower) and
     applied to repay the Refundable Swing Line Loan. On the day such Advances
     are made by the Lenders, the Swing Line Lender's Pro Rata Share of the
     Refundable Swing Line Loan shall be deemed to be paid with the proceeds of
     the Revolving Credit Advance made by the Swing Line Lender. Upon the making
     of any Advance under the Revolving Credit Loan pursuant to this subpart
     (c), the amount so funded shall become due under each Lender's Revolving
     Credit Note and shall no longer be owed under the Swing Line Note.
     Additionally, the Applicable Rate on such Refundable Swing Line Loan shall
     initially be the Base Rate Option. Each Lender's obligation to make
     Advances under its Revolving Credit Note referred to in this subpart (c)
     shall be absolute and unconditional and shall not be affected by any
     circumstance, happening or event whatsoever, whether or not similar to any
     of the foregoing.

          (d) Purchasing of Participations. In the event that (i) the Borrower
     is subject to any bankruptcy or insolvency proceedings, or (ii) if the
     Swing Line Lender otherwise requests, each Lender holding a Revolving
     Credit Note and/or a Foreign Currency Note shall 



                                      -16-

<PAGE>   22

     acquire without recourse or warranty, an undivided participation interest
     in the Swing Line Loan equal to such Lender's Pro Rata Share by paying to
     the Swing Line Lender, in same day funds, an amount equal to such Lender's
     Pro Rata Share of the Swing Line Loan. From and after the date on which
     such Lender purchases an undivided participation interest in the Swing Line
     Loan pursuant to this subsection, the Swing Line Lender shall distribute to
     such Lender (appropriately adjusted, in the case of interest payments, to
     reflect the period of time during which such Lender's participation
     interest is outstanding and funded) the Lender's Pro Rata Share of all
     payments of principal and interest in respect of the Swing Line Loan in
     like funds as received; provided, however, that in the event such payment
     received by the Swing Line Lender is required to be returned to the
     Borrower, such Lender shall return to the Swing Line Lender the portion of
     any amounts which such Lender had received from the Swing Line Lender in
     like funds.

     Section 2.04 Interest Rates and Interest Payment Dates.

          (a) The Applicable Rate for Advances under the Revolving Credit Loan
     shall either be the Base Rate Option or the LIBOR Option, as selected by
     Borrower pursuant to the procedures specified in parts (b) and (c) below.

     the Foreign Currency Rate Option. The Applicable Rate for the Swing Line
     Loan shall be the Swing Line Rate.

     Borrower may elect that any Advance under the Revolving Credit Loan shall
     bear interest at either the Base Rate Option or the LIBOR Option. In the
     event that the Borrower fails to designate an Applicable Rate for a
     Revolving Credit Loan, or in the event the Borrower fails to make an
     interest rate election in strict compliance herewith, then it shall be
     conclusively presumed that the Borrower has selected the Base Rate Option
     with a one (1) month Interest Rate Period for such Revolving Credit
     Advance.

          (c) Upon the occurrence of an Event of Default, the indebtedness
     described herein and all obligations hereunder shall bear interest at the
     Default Rate.

          (d) All interest other than interest calculated in accordance with the
     Base Rate Option, and all fees for the issuance of Letters of Credit shall
     be calculated on the basis of actual days elapsed in a 360-day year.
     Interest calculated in accordance with the Base Rate Option shall be
     calculated on the basis of a 365-366 (as applicable) day year.

          (e) Interest and principal shall be due and payable on the dates set
     forth in the Revolving Credit Notes, the Foreign Currency Notes and the
     Swing Line Note.

Pickard, C.E.O., James J. Gallogly, President, Laurence Y. Fairey, Chief
Financial Officer, J. Mark Merrill, Treasurer, or Jack B. Pearson, Jr.,
Assistant Treasurer. When a request for an Advance is made by an authorized

a method other than depositing such Advance into the Funding Account, Borrower
also authorizes Agent to follow such instructions.

     (b) Requests for Revolving Credit Loan. Borrower shall give the Agent at
least three (3) Business Days' prior notice of a proposed Advance at the LIBOR
Option (including conversions to a LIBOR Option and rollovers of existing
Advances at the LIBOR Option) and same Business Day prior notice by 11:00 a.m.
(Nashville, Tennessee time) of a proposed Advance at the Base Rate Option, under
the Revolving Credit Loan by presentation of the applicable Borrowing Request.
Any notice received by Borrower after 11:00 a.m. Nashville, Tennessee time will

LIBOR Option or (C) a rollover of an existing Advance at the LIBOR Option, and
(iv) if the Advance is to be entirely or partly made as a LIBOR Loan, the chosen
Interest Period. At least three (3) Business Days prior to the expiration of any
applicable Interest Period for an Advance at the LIBOR Option, the Borrower
shall designate a new Applicable Rate. In the event that the Borrower fails to
make such designation, then it shall be conclusively presumed that the Borrower
has selected the Base Rate Option until designated otherwise. With regard to
requests for Advances under the Revolving Credit Loan, the following shall
apply: (a) in the event that the Borrower designates the Base Rate Option as the
Applicable Rate, the requested Advance must be in a minimum amount of $1,000,000
and increments of $100,000 in excess thereof; and (b) in the event the Borrower
designates the LIBOR Option as the requested Applicable Rate, the requested
Advance must be in a minimum amount of $3,000,000 and increments of $500,000 in

requested date of borrowing, so long as it conforms to the required notification
period, (iii) whether the borrowing is to be (A) a new Advance at the Foreign
Currency Rate Option or (B) a rollover of an existing Advance at the Foreign

Borrower will designate a new Applicable Rate. In the event that the Borrower
fails to designate a rollover of an existing Foreign Currency Advance and does
not repay the Foreign Currency Advance at the end of the Interest Period, then
it shall be conclusively presumed that the Borrower has selected a new Foreign
Currency Rate Option for the next Interest Period. The requested Foreign
Currency Advance must be in a minimum U.S. Dollar Equivalent amount of
$1,000,000. Agent shall give prompt notice to Lenders of a request for a Foreign
Currency Advance on the date of such request, and each Lender shall wire
immediately available funds in such Foreign Currency to Agent by 1:00 p.m.
(Nashville, Tennessee time) the date of the requested Foreign Currency Advance.
The Borrower may request only one Foreign Currency Advance (except for renewals
of prior Foreign Currency Advances) in each calendar month.

for an Advance under the Swing Line Note no later than 11:00 A.M. (Nashville,
Tennessee time) followed by facsimile transmission of a Borrowing Request sent
to Agent. Borrower shall specify that such request is a request under the Swing
Line Note, and subject to availability under the Swing Line Note and provided
the request is made no later than 11:00 A.M. (Nashville, Tennessee time), the
Agent shall make the Advance by crediting the Funding Account no later than the
close of business on the day of the borrowing. Advances under the Swing Line
Loan shall be in a minimum amount of $100,000 and increments of $100,000 in
excess thereof.

     (e) No Liability. The Agent and the Lenders shall have no liability to
Borrower arising out of their compliance with the borrowing procedure specified
in this Section 2.05, except for acts of gross negligence or willful misconduct.

     (f) Warranty. The request by the Borrower of an Advance shall constitute a
warranty by the Borrower that as of the date of the request and as of the date
the Advance is made: (i) no Event of Default or Default Condition has occurred;
and (ii) the representations and warranties contained in Article III of this
Agreement remain true, correct, and accurate, except the representations and
warranties set forth in Section 3.06 which is made as of the date of this
Agreement and the representations and warranties in Sections 3.07 and 3.08 which
shall take into account transactions and subsequent events as permitted in this
Agreement.

Foreign Currency Loan and the Swing Line Loan shall be used to refinance the
existing credit facility of Borrower with SunTrust Bank, Nashville, N.A., in the
original maximum principal amount of up to $40,000,000 and all replacements
therefor, including without limitation existing letters of credit and
multi-currency facilities, and to fund Borrower's working capital needs, and for
Borrower's general corporate purposes, including capital expenditures and
acquisitions.

     Section 2.07 Participation. Any Lender shall have the right to enter into
one or more participation agreements with one or more of its Affiliates. Subject
to Borrower's approval under Section 12.12(d), each Lender shall have the right
to enter into one or more participation agreements with one or more banks, or
financial institutions which are not Affiliates of such Lender, on such terms
and conditions as such Lender shall deem advisable. Notwithstanding any
provisions of this section or Section 12.12(d), a Lender shall have the right to
enter into one or more participation



                                      -19-

agreements without the consent of Borrower, upon the occurrence of an Event of
Default. Borrower shall furnish a sufficient number of copies of reports and
certificates to Lenders so that Lenders and each participating lender shall
receive a copy of each such document.

     Section 2.08 Term of This Agreement. This Agreement shall mature and all
amounts under this Agreement, the Revolving Credit Notes, the Foreign Currency
Notes and the Swing Line Note shall be due and payable on the Maturity Date.
This Agreement shall be binding upon the Borrower so long as any portion of the
indebtedness described herein remains outstanding, provided and except,
Borrower's representations, warranties, and indemnity agreements shall survive
the payment in full of such indebtedness.

     Section 2.09 Payments to Principal Office; Debit Authority. Each payment

without defense, setoff, or counterclaim to Agent at its Principal Office in

Currency (as advanced or converted) for the Foreign Currency Loan, for the
account of Lenders and in immediately available funds before 11:00 a.m.
(Nashville, Tennessee time) on the date such payment is due. The Agent may, but
shall not be obligated to, debit the amount of any such payment which is not
made by such time to any deposit account of the Borrower with the Agent. Each
payment under the Swing Line Loan shall be made to Agent at its Principal Office
in U.S. Dollars and in immediately available funds before 11:00 a.m. (Nashville,
Tennessee time) on the date such payment is due. Payments received after 11:00
a.m. (Nashville, Tennessee time) will be deemed received on the next Business
Day. Agent shall wire, in immediately available funds, each such payment to
Lenders by 2:00 p.m. (Nashville, Tennessee time) on the date payments are
received.

     Section 2.10 Prepayment.

          (a) Required Prepayment. Whenever the aggregate amount outstanding
     under the Revolving Credit Loan exceeds the Maximum Total Amount, the
     Borrower shall immediately pay to Lenders such amounts as may be necessary
     to cause the aggregate principal amount outstanding under the Revolving
     Credit Loan to be equal to or less than the Maximum Total Amount permitted
     to be outstanding. Whenever the aggregate principal amount outstanding
     under the Foreign Currency Loan exceeds the Maximum Total Amount, the
     Borrower shall immediately pay to Agent such amounts as may be necessary to
     cause the aggregate principal amount outstanding under the Foreign Currency
     Loan to be equal to or less than the Maximum Total Amount permitted to be
     outstanding. Whenever the amount outstanding under the Swing Line Note
     exceeds the Maximum Total Amount permitted to be outstanding under the
     Swing Line Loan, the Borrower shall immediately pay to Agent such amounts
     as may be necessary to cause the principal amount outstanding under the
     Swing Line Note to be equal to or less than the Maximum Total Amount
     permitted to be outstanding under the Swing Line Loan;

     Loan, the Foreign Currency Loan and the Swing Line Loan as follows:




                                      -20-

<PAGE>   26

               (i) The Borrower may prepay the Swing Line Loan (provided that
          such reduction shall be in a principal amount of at least $100,000 and
          integral multiples of $100,000 in excess thereof) by written or oral
          notice to Agent no later than 11:00 a.m. (Nashville, Tennessee time)
          on the date of such prepayment, (if notice is oral, to be promptly
          thereafter confirmed in writing);

               (ii) Borrower may prepay Advances under the Revolving Credit
          Notes which bear interest at the Base Rate Option (provided that such
          reduction shall be in a principal amount of at least $1,000,000 and
          integral multiples of $100,000 in excess thereof) by written notice
          delivered to Agent no later than 11:00 a.m. (Nashville, Tennessee
          time) on the date of such prepayment and Agent shall promptly give
          notice to Lenders on the date of such prepayment;

               (iii) Borrower shall not have the right and option to prepay
          Advances under the Revolving Credit Notes bearing interest at the
          LIBOR Option until the expiration of the applicable Interest Period
          for such Advance. Any such reduction shall be in a principal amount of
          at least $1,000,000 and integral multiples of $100,000 in excess
          thereof and Borrower must give Agent at least three (3) Business Days'
          prior written notice of the amount and time of such prepayment. Should
          a prepayment of Advances bearing interest at the LIBOR Option be made
          prior to the expiration of the applicable Interest Period, Borrower
          agrees to immediately pay breakage costs determined by Agent and/or
          the Lenders to apply to such prepayment; provided, that nothing herein
          shall give Borrower the right to prepay such Advances prior to the end
          of the applicable Interest Period;

               (iv) Borrower shall not have the right and option to prepay
          Advances under the Foreign Currency Notes bearing interest at the
          Foreign Currency Rate Option until the expiration of the applicable
          Interest Period for such Advance. Any such reduction shall be in a
          principal amount of at least $1,000,000 and integral multiples of
          $100,000 in excess thereof and Borrower must give Agent at least three
          (3) Foreign Currency Business Days' prior written notice of the amount
          and time of such prepayment. Should a prepayment of Advances bearing
          interest at the Foreign Currency Rate Option be made prior to the
          expiration of the applicable Interest Period, Borrower agrees to
          immediately pay breakage costs determined by Agent and/or the Lenders
          to apply to such prepayment; provided, that nothing herein shall give
          Borrower the right to prepay such Advances prior to the end of the
          applicable Interest Period.

All prepayments will be applied first to unpaid expenses (if any), then to
accrued interest, then to principal.

          (c) Permanent Prepayments. The Borrower may permanently reduce the
     Revolving Credit Loan as follows:

               (i) Upon ten (10) days prior written notice delivered from
          Borrower to Agent, 




                                      -21-

<PAGE>   27

          the Borrower may permanently reduce the maximum principal amount that
          may be borrowed under the Revolving Credit Loan; provided that such
          reduction shall be in a principal amount of at least $5,000,000 and
          integral multiples of $1,000,000 in excess thereof, and provided that
          such reduction shall not reduce an outstanding Revolving Credit
          Advance with a LIBOR Option until the expiration of the applicable
          Interest Period for such Advance. In the event that a permanent
          reduction is made by the Borrower in the amount that may be borrowed
          under the Revolving Credit Loan, the Maximum Total Amount for the
          Revolving Credit Loan and the Revolving Credit Loan Commitment shall
          be reduced accordingly, and the Maximum Total Amounts with respect to
          the Letter of Credit Subcommitment, the Foreign Currency Commitment
          and the Swing Line Loan may be reduced as determined by Agent in
          Agent's discretion. Agent shall notify Lenders of any such reduction,
          within two (2) Business Days after receipt of such notice from
          Borrower.

     Section 2.11 Apportionment of Payments. Aggregate principal and interest
payments with respect to Advances under the Revolving Credit Loan shall be
apportioned among all outstanding Revolving Credit Loan Commitments to which
such payments relate proportionately to the Lenders' respective Pro Rata Share
of such Revolving Credit Loan Commitments. In the event the Agent receives
payment under the Revolving Credit Loan by 11:00 A.M. (Nashville, Tennessee
time), then the Agent shall promptly distribute to each Lender its share of all
such payments received by the Agent on the date of Agent's receipt of such
payments. Payments received subsequent to 11:00 A.M. (Nashville, Tennessee time)
shall be treated as received on the next succeeding Business Day. Aggregate
principal and interest payments with respect to Advances under the Foreign
Currency Loan shall be apportioned (in the Foreign Currency repaid by Borrower)
among all outstanding Foreign Currency Commitments to which such payments relate
proportionately to the Lenders' respective Pro Rata Share of such Foreign
Currency Commitments. In the event the Agent receives payment under the Foreign
Currency Loan by 11:00 A.M. (Nashville, Tennessee time), then the Agent shall
promptly distribute to each Lender its share of all such payments received by
the Agent on the date of Agent's receipt of such payments. Payments received
subsequent to 11:00 A.M. (Nashville, Tennessee time) shall be treated as
received on the next succeeding Foreign Currency Business Day.

     Section 2.12 Sharing of Payments, Etc. If any Lender shall obtain any
payment or reduction (including, without limitation, any amounts received as
adequate protection of a deposit treated as cash collateral under the Bankruptcy
Code) of the indebtedness relating to Advances under the Revolving Credit Loan
and/or Foreign Currency Loan (whether voluntary, involuntary, through the
exercise of any right of set-off or otherwise) in excess of its Pro Rata Share
of payments or reductions of the Revolving Credit Loan, such Lender shall
forthwith (a) notify the Agent of such receipt (and the Agent shall notify the
Lenders), and (b) purchase from the other Lenders such participations in the
Revolving Credit Loan and/or the Foreign Currency Loan as shall be necessary to
cause such purchasing Lender to share the excess payment or reduction, net of
costs incurred in connection therewith, ratably with each of them, provided that
if all or any portion of such excess payment or reduction is thereafter
recovered from such purchasing Lender or additional costs are incurred, the
purchase shall be rescinded and the purchase price restored to the extent of
such recovery or such additional costs, but without interest unless the Lender
obligated to return such funds is required to pay interest on such funds.
Borrower agrees that any Lender so purchasing a participation from 




                                      -22-

<PAGE>   28

another Lender pursuant to this Section 2.12 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender were the
direct creditor of the Borrower in the amount of such participation.

     Section 2.13 Right of Offset, Etc. The Borrower hereby agrees that, in
addition to (and without limitation of) any right of set-off, banker's lien or
counterclaim the Lenders may otherwise have, the Lenders shall be entitled, at
their option, to offset balances held by any of them at any of their offices
against any principal of or interest on the indebtedness described herein which
is not paid when due by reason of a failure by the Borrower to make any payment
when due to such Lender and/or any of the other Lenders, and/or the Swing Line
Lender (regardless whether such balances are then due to the Borrower), in which
case such offsetting Lender shall promptly notify the Borrower, provided that
its failure to give such notice shall not affect the validity thereof. Net of
costs incurred in connection with any such offset, each Lender agrees to share
pro-rata with the other Lenders and the Swing Line Lender, based on the amounts
of the Revolving Credit Loan, Foreign Currency Loan and the Swing Line Loan held
by such Lenders and the Swing Line Lender, any proceeds realized from the
exercise of such offset rights.

     Section 2.14 Commitment Fee. Commencing on September 30, 1997 and on the
last day of each Fiscal Quarter thereafter (or if not a Business Day, the next
succeeding Business Day) and on the Maturity Date, the Borrower shall pay to the
Agent for distribution to the Lenders based on their Pro Rata Share, a
commitment fee equal to the Applicable Commitment Fee calculated on the average
unused portion of the Revolving Credit Loan for the preceding Fiscal Quarter (or
portion thereof); provided that the payment made on September 30, 1997 shall be
for a time period from the Closing Date to September 30, 1997. The commitment
fee shall be calculated based on a year of 360 days for the actual number of
days elapsed.

     Section 2.15 Usury. The parties to this Agreement intend to conform
strictly to applicable usury laws as presently in effect. Accordingly, if the
transactions contemplated hereby would be usurious under applicable law
(including the laws of the United States of America and the State of Tennessee),
then, in that event, notwithstanding anything to the contrary in any Loan
Document or agreement executed in connection with the indebtedness described
herein, Borrower, Agent, and Lenders agree as follows: (i) the aggregate of all
consideration that constitutes interest under applicable law which is contracted
for, charged, or received under any of the Loan Documents or agreements, or
otherwise in connection with the indebtedness described herein, shall under no
circumstance exceed the maximum lawful rate of interest permitted by applicable
law, and any excess shall be credited on the indebtedness by the holder thereof
(or, if the indebtedness described herein shall have been paid in full, refunded
to Borrower); and (ii) in the event that the maturity of the indebtedness
described herein is accelerated as a result of any Event of Default or
otherwise, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest may never include more than the maximum
amount of interest permitted by applicable law, and excess interest, if any, for
which this Agreement provides, or otherwise, shall be cancelled automatically as
of the date of such acceleration or prepayment and, if previously paid, shall be
credited on the indebtedness described herein (or, if the indebtedness shall
have been paid in full, refunded to Borrower).

     Section 2.16 Interest Rate Not Ascertainable, Etc. In the event that the
Agent shall in good faith have determined that on any date for determining the
LIBOR Rate, by reason of any changes arising after the date of this Agreement
affecting the London interbank market or the Agent's position in such market,
adequate and fair means do not exist for ascertaining the applicable interest
rate on the basis provided for in the definition of LIBOR Rate, then, and in any
such event, the Agent shall forthwith give notice (by telephone confirmed in
writing) to the Borrower of such determination and a summary of the basis for
such determination. At the expiration of any Interest Rate Period then in effect
and until the Agent notifies the Borrower that the circumstances giving rise to
the suspension described herein no longer exist (which notice shall be given
forthwith after such determination is made by the Agent), all Loans shall bear
interest at the Base Rate Option. In the event that the Agent shall in good
faith have determined that on any date for determining a Foreign Currency Rate
Option, by reason of any changes arising after the date of this Agreement
affecting the interbank market for such Foreign Currency or the Agent's position
in such market, adequate and fair means do not exist for ascertaining the
applicable interest rate on the basis provided for in the definition of Foreign
Currency Rate Option, then, and in any such event, the Agent shall forthwith
give notice (by telephone confirmed in writing) to the Borrower of such
determination and a summary of the basis for such determination. At the
expiration of any Interest Period then in effect and until the Agent notifies
the Borrower that the circumstances giving rise to the suspension described
herein no longer exist (which notice shall be given forthwith after such
determination is made by the Agent), the Foreign Currency Loans for which a
Foreign Currency Rate Option cannot be established under this Section shall be
converted at the end of the applicable Interest Period to a Revolving Credit
Loan and shall thereafter bear interest at the Base Rate Option.

     Section 2.17 Illegality. (a) In the event that the Agent shall have
determined any time that the making or continuance of any Advance bearing
interest at the LIBOR Option or the Foreign Currency Rate Option has become
unlawful by compliance by any Lender (an "Affected Lender") in good faith with
any applicable law, governmental rule, regulation, guideline or order (whether
or not having the force of law and whether or not failure to comply therewith
would be unlawful), then, in any such event, the Agent shall give prompt notice
(by telephone confirmed in writing) to the Borrower of such determination and a
summary of the basis for such determination.

     (b) Upon the giving of the notice to the Borrower referred to in Section
2.17(a), the Borrower's right to elect a LIBOR Option or a Foreign Currency Rate
Option shall be immediately suspended, and all outstanding Advances made by the
Affected Lender shall be under the Revolving Credit Loan and shall bear interest
at the Base Rate Option after the current Interest Period has expired. The
Borrower shall have the right and option to replace the Affected Lender pursuant
to Section 12.13 hereof, for so long as the Affected Lender which remains under
the disability described in Section 2.17(a).

     Section 2.18 Increased Costs. (a) If by reason of (i) after the date
hereof, the introduction of or any change (including, without limitation, any
change by way of imposition or increase of reserve requirements) in or in the
interpretation of any law or regulation, or (ii) the compliance with any
guideline or request from any central bank or other governmental authority or
quasi-governmental authority exercising control over banks or financial
institutions generally (whether or not having the force of law):




                                      -24-


<PAGE>   30

          (A) the Agent or any Lender shall be subject to any tax (including a
     foreign withholding tax), duty or other charge with respect to any Advances
     bearing interest at the LIBOR Option or at the Foreign Currency Rate Option
     (all such Advances being collectively referred to as the "LIBOR/Foreign
     Currency Loans") or its obligation to make LIBOR Loans or Foreign Currency
     Loans, or the basis of taxation of payments to the Agent or any Lender of
     the principal of or interest on its LIBOR/Foreign Currency Loans or its
     obligation to make LIBOR/Foreign Currency Loans shall have changed (except
     for changes in the tax on the overall net income of the Agent or such
     Lender, or similar taxes, pursuant to the laws of jurisdictions with taxing
     authority over the Agent or such Lender); or

          (B) any reserve (including, without limitation, any reserve imposed by
     the Board of Governors of the Federal Reserve System), special deposit or
     similar requirement against assets of, deposits with or for the account of,
     or credit extended by, the Agent or any Lender shall be imposed or deemed
     applicable or any other condition affecting its LIBOR/Foreign Currency
     Loans or its obligation to make LIBOR/Foreign Currency Loans shall be
     imposed on the Agent, any Lender, the London interbank market or the
     interbank market for a Foreign Currency;

and as a result thereof there shall be any increase in the cost to the Agent or
such Lender (a "LIBOR/Foreign Currency Affected Lender") of agreeing to make or
making, funding or maintaining LIBOR/Foreign Currency Loans (except to the
extent already included in the determination of the interest rate for
LIBOR/Foreign Currency Loans), or there shall be a reduction in the amount
received or receivable by the Agent or any LIBOR/Foreign Currency Affected
Lender, then the Borrower shall from time to time, upon written notice from and
demand in good faith by the Agent, pay to the Agent for the account of the
Lenders (or any LIBOR/Foreign Currency Affected Lender) within five (5) Business
Days after the date of such notice and demand, additional amounts sufficient to
indemnify the Agent or such LIBOR/Foreign Currency Affected Lender against such
increased cost; provided, however, that nothing in this section shall require
Borrower to indemnify the Agent or any Lender for withholding taxes imposed by
the United States; provided that Borrower shall have the right and option to
replace a LIBOR Affected Lender pursuant to the terms of Section 12.12 hereof.

     (b) If the Agent shall in good faith determine that at any time, because of
the circumstances described in Section 2.18(a)(i) or (ii) arising after the date
of this Agreement affecting the Agent or any Lender, the London interbank market
or the interbank market for an applicable Foreign Currency, or the Agent or any
Lender's position in such market, the calculations for the interest rates for
LIBOR Loans or Foreign Currency Loans as determined by the Agent or any Lender
will not adequately and fairly reflect the cost to the Agent or any Lender of
funding such LIBOR Loans or Foreign Currency Loans, the Agent shall forthwith
give notice (by telephone confirmed in writing) to the Borrower of such advice,
and a summary of the basis for such determination, and then, and in any such
event and until Agent notifies the Borrower that such circumstances no longer
exist (which notice shall be given forthwith after such determination is made by
the Agent):

          (i) The Borrower's right to request, and the Agent's and any Lender's
     obligation to make or permit portions of the indebtedness described herein
     to remain outstanding past the 




                                      -25-

<PAGE>   31

     last day of the then current Interest Rate Period as LIBOR Loans shall be
     immediately suspended; and

          (ii) After the last day of the then-current Interest Rate Period, all
     such indebtedness described in this Section shall be converted to a
     Revolving Credit Loan and bear interest at the Base Rate Option.

     Section 2.19 Mitigation. Each Lender shall take such commercially
reasonable steps as it may determine are not disadvantageous to it, including
changes in lending offices to the extent feasible, in order to reduce additional
payments by the Borrower pursuant to Section 2.18 and to make the LIBOR Option
and the Foreign Currency Rate Option available under Sections 2.17 and 2.18
hereof.

     Section 2.20 Increase in Revolving Credit Loan Commitments.

     (a) Borrower may, at any time by written notice to the Lenders, request
that the Revolving Credit Commitments be increased up to an amount not to exceed
$100,000,000 in the aggregate (the "Requested Commitment Amount") on a pro rata
basis based on the Pro Rata Shares of the Lenders. No Lender (or any successor
thereto) shall have any obligation to increase its Revolving Credit Loan
Commitment or its other obligations under this Agreement and the other Loan
Documents, and any decision by a Lender to increase its Revolving Credit Loan
Commitment shall be made in its sole discretion independently from any other
Lender or the Agent. Within fifteen (15) Business Days from each Lender's
receipt of such request from the Borrower, each Lender shall notify the Agent in
writing of whether or not it will agree to increase its Revolving Credit Loan
Commitment and by what amount it will agree to increase its Loan Commitment, up
to its Pro Rata Share of the Requested Commitment Amount. Borrower agrees to
execute and deliver to Agent and Lenders such amendments to documents,
promissory notes, resolutions, certificates, opinions and other documentation
and items as Agent and/or any of the Lenders may request in connection
therewith, all of which must be in form and substance satisfactory to Agent and
Lenders, and Borrower agrees to pay all costs and expenses (including without
limitation legal fees) of Agent and Lenders in connection therewith.

     (b) In the event that the aggregate amount to which the Lenders are willing
to increase their Revolving Credit Loan Commitments is less than the Requested
Commitment Amount based on the written notices delivered by the Lenders to the
Agent, the Agent shall first offer to the Lenders who have agreed to increase
their Revolving Credit Loan Commitments the opportunity to further increase
their Revolving Credit Loan Commitments up to an amount equal to the Requested
Commitment Amount. Such Lenders shall promptly respond in writing to the Agent,
whether or not it will agree to further increase its Revolving Credit Loan
Commitment and by what amount it will agree to further increase its Revolving
Credit Loan Commitment. Within five (5) Business Days after receipt of all
responses from such Lenders, the Agent shall inform the Borrower and all Lenders
in writing of the amount by which each Lender will increase its Revolving Credit
Loan Commitment.

     (c) In the event that the aggregate amount to which the Lenders are willing
to increase their Revolving Credit Loan Commitments is less than the Requested
Commitment Amount based on the notice from the Agent to the Borrower and all
Lenders, the Borrower shall have the right, within 




                                      -26-

<PAGE>   32

sixty (60) days after receipt of such notice from the Agent, to obtain
commitments from new banks or financial institutions in an aggregate amount such
that the existing Revolving Credit Loan Commitments, plus the aggregate
principal amount by which the Lenders are willing to increase their Revolving
Loan Commitments, plus the aggregate principal amount of the new commitments by

<PAGE>   51

          (b) The Borrower represents that its Property and any current
     operation concerning its Property (and the Property of any Subsidiary) and
     its business operations are not in material violation of any applicable
     Environmental Law, and the Borrower has no actual knowledge or any notice

     Agent.

     proceedings, costs and expenses (including, without limitation, reasonable
     attorneys' fees), arising directly or indirectly from or out of, or in any
     way connected with (i) the presence of any Hazardous Substances on any of
     its Property (or the Property of a Subsidiary) in violation of any
     Environmental Law; (ii) any violation or alleged violation of any
     Environmental Law relating to Hazardous Substances on any of its Property
     (or the Property of a Subsidiary), whether attributable to events occurring
     before or after acquisition of any of such Property; (iii) any violation of
     any Environmental Law by the Borrower (or a Subsidiary) resulting from the

this Agreement, the other Loan Documents and all other instruments and
agreements referred to herein or therein, and to exercise such powers and to

responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any of the Lenders, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or otherwise be imposed upon or exist against the Agent.

     Section 12.02 Authorization of Agent with Respect to the Loan Documents.

     (a) Each Lender hereby authorizes the Agent to enter into each of the Loan
Documents and to take all action contemplated thereby, all in its capacity as
Agent for the ratable benefit of the Lenders. All rights and remedies under the
Loan Documents may be exercised by the Agent for the benefit of the Agent and
the Lenders upon the terms thereof. The Lenders further agree that the Agent may
assign its rights and obligations under any of the Loan Documents to any
Affiliate of the Agent, if necessary or appropriate under applicable law, which
assignee in each such case shall (subject to compliance with any requirements of
applicable law governing the assignment of such Loan Documents) be entitled to
all the rights of the Agent under and with respect to the applicable Loan
Document.

     (b) The Agent shall administer the Loans described herein and the Loan
Documents on behalf of and for the benefit of the Lenders in all respects as if
the Agent were the sole Lender under the Loan Documents, except that:

          (i) The Agent shall administer the Loans and the Loan Documents with a
     degree of care at least equal to that customarily employed by the Agent in
     the administration of similar credit facilities for its own account.

          (ii) The Agent shall not, without the consent of the Majority Lenders,
     take any of the following actions:

               (D) accelerate the indebtedness described in the Credit Agreement
          following an Event of Default;

               (E) initiate litigation or pursue other remedies to enforce the
          obligations contained in any Loan Document or to collect the

               (A) extend the maturity of any payment of principal of or

               (B) reduce any fees paid to or for the benefit of Lenders under
          this Credit Agreement;



                                      -47-

<PAGE>   53

          principal of, or interest on the indebtedness described herein, or any
          fees hereunder;

               (G) modify the definition of Majority Lenders; or

               (H) modify this Section 12.02(b)(ii) or (iii).

          (c) The Agent, upon its receipt of actual notice thereof, shall notify
     the Lenders of: (i) each proposed action that would require the consent of
     the Lenders as set forth herein, or (ii) any action proposed to be taken by
     the Agent in the administration of the Loans and Loan Documents not in the
     ordinary course of business; provided that any failure of the Agent to give
     the Lenders any such notice shall not alone be the basis for any liability
     of the Agent to the Lenders except for the Agent's gross negligence or
     willful misconduct.

          (d) The Lenders agree that the Agent shall incur no liability under or
     in respect of this Agreement with respect to anything which it may do or
     refrain from doing in the reasonable exercise of its judgment or which may
     seem to it to be necessary or desirable in the circumstances, except for
     its gross negligence or willful misconduct.

          (e) The Agent shall not be liable to the Lenders or to any Lender in
     acting or refraining from acting under this Agreement or any other Loan
     Document in accordance with the instructions of the Majority Lenders or all
     of the Lenders, where expressly required by this Agreement, and any action
     taken or failure to act pursuant to such instructions shall be binding on
     all Lenders. In each circumstance where any consent of or direction from
     the Majority Lenders or all of the Lenders is required or requested by
     Agent, the Agent shall send to the Lenders a notice setting forth a
     description in reasonable detail of the matter as to which consent or
     direction is requested and the Agent's proposed course of action with
     respect thereto. In the event the Agent shall not have received a response
     from any Lender within five (5) Business Days after Agent sends such
     notice, such Lender shall be deemed not to have agreed to the course of
     action proposed by the Agent.

     Section 12.03 Agent's Duties Limited; No Fiduciary Duty. The Lenders agree
that the Agent shall have no duties or responsibilities except those expressly
set forth in this Agreement and the other Loan Documents. The Lenders agree that
none of the Agent nor any of its respective officers, directors, employees or
agents shall be liable for any action taken or omitted by it as such hereunder
or in connection herewith, unless caused by its or their gross negligence or
willful misconduct. The Agent shall not have by reason of this Agreement a
fiduciary relationship to or in respect of any Lender, and nothing in this
Agreement, express or implied, is intended to or shall be so construed as to
impose upon the Agent any obligations in respect of this Agreement or the other
Loan Documents except as expressly set forth herein.

     Section 12.04 No Reliance on the Agent. (A) EACH LENDER REPRESENTS AND
WARRANTS TO THE AGENT AND THE OTHER LENDERS THAT INDEPENDENTLY AND WITHOUT
RELIANCE UPON THE AGENT, EACH LENDER, TO THE EXTENT IT DEEMS APPROPRIATE, HAS
MADE AND SHALL CONTINUE TO MAKE (I) ITS OWN INDEPENDENT INVESTIGATION OF THE
FINANCIAL CONDITION AND AFFAIRS OF THE BORROWER, THE GUARANTORS AND ANY
SUBSIDIARY IN CONNECTION WITH THE TAKING OR NOT TAKING OF ANY ACTION IN
CONNECTION HEREWITH, AND (II) ITS OWN APPRAISAL OF THE CREDITWORTHINESS OF THE
BORROWER, THE GUARANTORS AND ANY SUBSIDIARY, AND, EACH LENDER FURTHER AGREES
THAT, EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT, THE AGENT SHALL HAVE NO
DUTY OR RESPONSIBILITY, EITHER INITIALLY OR ON A CONTINUING BASIS, TO PROVIDE
ANY LENDER WITH ANY CREDIT OR OTHER INFORMATION WITH RESPECT THERETO, WHETHER
COMING INTO ITS POSSESSION BEFORE THE MAKING OF THE LOANS OR AT ANY TIME OR
TIMES THEREAFTER. AS LONG AS ANY OF THE LOANS ARE OUTSTANDING AND/OR ANY AMOUNT
IS AVAILABLE TO BE REQUESTED OR BORROWED HEREUNDER, OR THIS AGREEMENT AND THE
LOAN DOCUMENTS HAVE NOT BEEN CANCELLED AND TERMINATED, EACH LENDER SHALL
CONTINUE TO MAKE ITS OWN INDEPENDENT EVALUATION OF THE FINANCIAL CONDITION AND
AFFAIRS OF THE BORROWER, THE GUARANTORS AND THE SUBSIDIARIES.

     (b) The Agent shall not be responsible to any Lender for any recitals,
statements, information, representations or warranties herein or in any
document, certificate or other writing delivered in connection herewith or for
the execution, effectiveness, genuineness, validity, enforceability,
collectability, priority or sufficiency of this Agreement, the Revolving Credit
Notes, the Swing Line Note, the Foreign Currency Notes, the Guaranties, the
Negative Pledge, the other Loan Documents, or any other documents contemplated
hereby or thereby, or the financial condition of the Borrower, the Guarantors
and any Subsidiary, or be required to make any inquiry concerning either the
performance or observance of any of the terms, provisions or conditions of this
Agreement, the Revolving Credit Notes, the Foreign Currency Notes, the Swing
Line Note, the Guaranties, the other Loan Documents or the other documents
contemplated hereby or thereby, or the financial condition of the Borrower, the
Guarantors and any Subsidiary, or the existence or possible existence of any
Default Condition or Event of Default.

     Section 12.05 Certain Rights of Agent. The Lenders agree that if the Agent
shall request instructions from the Majority Lenders (or all of the Lenders
where unanimity is expressly required under the terms of this Agreement) with
respect to any action or actions (including the failure to act) in connection
with this Agreement, the Agent shall be entitled to refrain from such act or
taking such act, unless and until the Agent shall have received instructions
from the Majority Lenders (or all of the Lenders where unanimity is expressly
required under the terms of this Agreement); and the Agent shall not incur
liability to any Person by reason of so refraining. Without limiting the
foregoing, no Lender shall have any right of action whatsoever against the Agent
as a result of the Agent acting or refraining from acting hereunder in
accordance with the instructions of the Majority Lenders (or, with regard to
acts for which the consent of all of the Lenders is expressly required under the
terms of this Agreement, in accordance with the instructions of all of the
Lenders).

     Section 12.06 Reliance by Agent. The Lenders agree that the Agent shall be
entitled to rely,



                                      -49-

<PAGE>   55

and shall be fully protected in relying, upon any note, writing, resolution,
notice, statement, certificate, telex, teletype or telecopier message,
cablegram, radiogram, order or other documentary, teletransmission or telephone
message reasonably believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person. The Lenders agree that the Agent may
consult with legal counsel (including counsel for any Lender), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken by it in good faith in accordance with
the advice of such counsel, accountants or experts.

     Section 12.07 Indemnification of Agent. To the extent the Agent is not
reimbursed and indemnified by the Borrower, each Lender will reimburse and
indemnify the Agent, ratably according to their respective Pro Rata Share, for,
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including fees of
experts, consultants and counsel and disbursements) or disbursements of any kind
or nature whatsoever that may be imposed on, incurred by or asserted against the
Agent in performing its duties hereunder, in any way relating to or arising out
of this Agreement or the other Loan Documents; provided that no Lender shall be
liable to the Agent for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Agent's gross negligence or willful misconduct. The
obligations and indemnifications arising under this Section 12.07 shall survive
termination of this Agreement, repayment of the Loans and indebtedness arising
in connection with the Letters of Credit and expiration of the Letters of
Credit.

     Section 12.08 The Agent in its Individual Capacity. With respect to its
obligation to lend under this Agreement, the Loan made by it and the Revolving
Credit Note issued to it, the Agent shall have the same rights and powers
hereunder as any other Lender or holder of a Revolving Credit Note and may
exercise the same as though it were not performing the duties of Agent specified
herein; and the terms "Lenders," "Majority Lenders," "holders of Revolving
Credit Notes," "holders of Foreign Currency Notes," or any similar terms shall,
unless the context clearly otherwise indicates, include the Agent in its
individual capacity. The Agent also may exercise the rights and remedies of the
Swing Line Lender. The Agent and its Affiliates may accept deposits from, lend
money to, and generally engage in any kind of banking, trust, financial advisory
or other business with the Borrower or any Subsidiary of the Borrower as if it
were not performing the duties specified herein as Agent, and may accept fees
and other consideration from the Borrower for services in connection with this
Agreement and otherwise without having to account for the same to the Lenders.

     Section 12.09 Holders of Notes. The Agent and the Borrower may deem and
treat the payee of any Revolving Credit Notes and any Foreign Currency Notes as
the owner thereof for all purposes hereof unless and until a written notice of
the assignment or transfer thereof shall have been filed with the Agent and the
Borrower. Any request, authority or consent of any Person who, at the time of
making such request or giving such authority or consent, is the holder of any
Revolving Credit Note shall be conclusive and binding on any subsequent holder,
transferee or assignee of such Revolving Credit Note.

     Section 12.10 Successor Agent. (a) The Agent may resign at any time by
giving written notice thereof to the Lenders and the Borrower and may be removed
at any time with cause by the Majority Lenders; provided, however, the Agent may
not resign or be removed until (i) a successor Agent has been appointed and
shall have accepted such appointment, (ii) the successor Agent has assumed all
responsibility for issuance of the Letters of Credit and the successor Agent has
assumed in the place




                                      -50-

<PAGE>   56

and stead of the Agent all existing liability under outstanding Letters of
Credit, and (iii) the successor Agent has assumed in the place and stead of the
Agent all liability and responsibility of the Swing Line Lender, including the
purchase by the successor Agent from the Agent of the Swing Line Lender's
position in the Swing Line Note. The transactions described in the immediately
preceding sentence shall be accomplished pursuant to written agreements
reasonably satisfactory to the Agent and the successor Agent. Upon any such
resignation or removal, the Majority Lenders shall have the right to appoint a
successor Agent with the consent of Borrower, which shall not be unreasonably
withheld. If no successor Agent shall have been so appointed by the Majority
Lenders, and shall have accepted such appointment, within thirty (30) days after
the retiring Agent's giving of notice of resignation or the Majority Lenders'
removal of the retiring Agent, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent (with the consent of Borrower, which will not
be unreasonably withheld), which shall be a bank that maintains an office in the
United States, or a commercial bank organized under the laws of the United
States of America or any State thereof, or any Affiliate of such bank, having a
combined capital and surplus of at least $100,000,000.

     (b) Upon the acceptance of any appointment as the Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations under
this Agreement. After any retiring Agent's resignation or removal hereunder as
Agent, the provisions of this Article XII shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was an Agent under this
Agreement.

     Section 12.11 Notice of Default or Event of Default. In the event that the
Agent or any Lender shall acquire actual knowledge, or shall have been notified,
of any Default Condition or Event of Default (other than through a notice by one
party hereto to all other parties), the Agent or such Lender shall promptly
notify the Agent, and the Agent shall take such action and assert such rights
under this Agreement as the Majority Lenders shall request in writing, and the
Agent shall not be subject to any liability by reason of its acting pursuant to
any such request. If, following notification by Agent to Lenders, the Majority
Lenders (or all of the Lenders if required hereunder) shall fail to request the
Agent to take action or to assert rights under this Agreement in respect of any
Default Condition or Event of Default within five (5) Business Days after their
receipt of the notice of any Default Condition or Event of Default from the
Agent or any Lender, or shall request inconsistent action with respect to such
Default Condition or Event of Default, the Agent may, but shall not be required
to, take such action and assert such rights (other than rights under Article
VIII hereof) as it deems in its discretion to be advisable for the protection of
the Lenders.

     Section 12.12 Benefit of Agreement.

     (a) Any Lender may make, carry or transfer Loans at, to or for the account
of, any of its branch offices or the office of an Affiliate of such Lender,
provided that no such action shall increase the cost of the Loans to the
Borrower.

     (b) Each Lender may assign a pro rata portion of its interests, rights and
obligations under this Agreement, including all or a portion of any of its
Revolving Credit Loan Commitment (including without limitation its commitment to
participate in Letters of Credit) and its Foreign Currency Commitment, to any
Eligible Assignee; provided, however, that (i) the amount of the Revolving
Credit Loan Commitment of the assigning Lender subject to each assignment
(determined as of the date the assignment and acceptance with respect to such
assignment is delivered to the Agent) shall not 



                                      -51-

<PAGE>   57

be less than an amount equal to $10,000,000 or greater integral multiples
thereof; (ii) the assignment of the Revolving Credit Loan Commitment shall also
assign Lender's same pro rata interest in the Foreign Currency Commitment; and
(iii) the parties to each such assignment shall execute and deliver to the Agent
and the Borrower an Assignment and Acceptance, together with a Revolving Credit
Note(s) and a Foreign Currency Note(s), subject to such assignment and, unless
such assignment is to an Affiliate of such Lender, a processing and recordation
fee payable to Agent of $3,000. Borrower shall not be responsible for such
processing and recordation fee or any costs or expenses incurred by any Lender
or the Agent in connection with such assignment. From and after the effective
date specified in each Assignment and Acceptance, which effective date shall be
at least five (5) Business Days after the execution thereof, the assignee
thereunder shall be a party hereto and to the extent of the interest assigned by
such Assignment and Acceptance, have the rights and obligations of a Lender
under this Agreement. Notwithstanding the foregoing, the assigning Lender must
retain after the consummation of such Assignment and Acceptance, a minimum
aggregate amount of Revolving Credit Loan Commitment of $10,000,000; provided,
however, no such minimum amount shall be required with respect to any such
assignment made at any time there exists an Event of Default hereunder, and no
such minimum amount shall be required in the case of an assignment by an
assigning Lender to an affiliate bank of such assigning Lender (provided that
such affiliate bank is a United States national bank or a state banking
institution of any state in the United States). Within five (5) Business Days
after receipt of the notice and the Assignment and Acceptance, Borrower, at
their own expense, shall execute and deliver to the Agent, in exchange for the
surrendered Revolving Credit Note(s) and Foreign Currency Note(s), new Revolving
Credit Note(s) and Foreign Currency Note(s) to the order of the Eligible
Assignee in a principal amount equal to the applicable Revolving Credit Loan
Commitment and Foreign Currency Commitment assumed by it pursuant to such
Assignment and Acceptance, as well as a new Revolving Credit Note(s) (or Foreign
Currency Note(s) to the assigning Lender in the amount of its retained Revolving
Credit Loan Commitment and Foreign Currency Commitment. Such new Revolving
Credit Note(s) and Foreign Currency Note(s) to the Eligible Assignee and to the
assigning Lender shall be in an aggregate principal amount equal to the
aggregate principal amount of such surrendered Revolving Credit Note(s) and
Foreign Currency Note(s), shall be dated the date of the surrendered Revolving
Credit Note(s) and Foreign Currency Note(s) that they replace, and shall
otherwise be in substantially the form attached hereto as respective Exhibits A
and B, as applicable.

     (c) No assignment of all or any portion of this Agreement by any Lender
shall be permitted without compliance with the provisions of Section 12.12(b)
hereof, or if such assignment would violate any applicable securities law. In
connection with its execution and delivery hereof each Lender represents that it
is acquiring its interest herein for its own account for investment purposes and
not with a view to further distribution thereof, and shall require any proposed
assignee to furnish similar representations to the Agent and the Borrower.

     (d) Each Lender may, without the consent of Borrower or the Agent but
subject to the provisions of Section 2.07, sell participations in its respective
Revolving Credit Loan Commitment (including the Letter of Credit) and Foreign
Currency Commitment to such Lender's Affiliate(s), but sales of participations
to Persons other than such Lender's Affiliates shall be made only with the prior
written consent of the Borrower (which consent shall not be unreasonably
withheld or delayed) and in all events subject to said Section. Provided,
however, that (i) no Lender may sell a participation in its aggregate Revolving
Credit Loan Commitment (including the Letter of Credit) and Foreign Currency
Commitment (after giving effect to any permitted assignment hereof) unless it
retains an aggregate



                                      -52-

<PAGE>   58

exposure of at least fifty percent (50%) of such commitments (except that no
such limitation shall be applicable to any such participation sold at any time
there exists an Event of Default hereunder), (ii) such Lender's obligations
under this Agreement shall remain unchanged, (iii) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, and (iv) Borrower and the Agent and other Lenders shall continue to
deal solely and directly with each Lender in connection with such Lender's
rights and obligations as provided in this Agreement and the other Loan
Documents. Each Lender shall promptly notify in writing the Agent of any sale of
a participation hereunder.

     (e) Any Lender or participant may, in connection with the assignment or
participation or proposed assignment or participation, pursuant to this Section
12.12, disclose to the assignee or participant or proposed assignee or
participant any information relating to Borrower or any Subsidiary, furnished to
such Lender by or on behalf of Borrower. With respect to any disclosure of
confidential, non-public, proprietary information, such proposed assignee or
participant shall agree to use the information only for the purpose of making
any necessary credit judgments with respect to this credit facility and not to
use the information in any manner prohibited by any law, including without
limitation, the securities laws of the United States. The proposed participant
or assignee shall agree in writing not to disclose any of such information
except (i) to directors, employees, auditors or counsel to whom it is necessary
to show such information, each of whom shall be informed of the confidential
nature of the information and agree to maintain the confidentiality thereof as
described herein, (ii) in any statement or testimony pursuant to a subpoena or
order by any court, governmental body or other agency asserting jurisdiction
over such entity, or as otherwise required by law (provided prior notice is
given to Borrower and the Agent unless otherwise prohibited by the subpoena,
order or law), and (iii) upon the request or demand of any regulatory agency or
authority with proper jurisdiction. The proposed participant or assignee, and
such representatives, shall further agree to return to Borrower all documents or
other written material and copies thereof received from any Lender, the Agent or
Borrower relating to such confidential information.

     (f) Any Lender may at any time assign all or any portion of its rights in
this Agreement, the Revolving Credit Notes, the Foreign Currency Notes and other
instruments described herein issued to it to a Federal Reserve Bank; provided
that no such assignment shall release the assigning Lender from any of its
obligations hereunder.

     Section 12.13 Removal of Lender. In the event that any Lender (the
"Specified Lender") (a) fails to perform its obligation to fund any portion of
the Loan when required to do so by the terms




                                      -53-
<PAGE>   59


of this Agreement or excused only by Section 2.17, (b) demands payment in
respect of increased costs pursuant to Section 2.18 in an amount the Borrower
reasonably deems materially in excess of the amounts in respect thereof demanded
by the other Lenders, or (c) refuses to consent to a proposed amendment,
modification, consent or other action requiring unanimity among the Lenders
under the terms of this Agreement, as to which the Majority Lenders have given
such consent, then, so long as no Event of Default or Default Condition exists,
the Borrower shall have the right to seek a replacement Lender which is
reasonably satisfactory to the Agent (a "Replacement Lender"). The Replacement
Lender shall purchase the interest of the Specified Lender in the Loan and shall
assume the obligations of the Specified Lender hereunder upon execution by the
Replacement Lender of an Assignment and Acceptance and the tender by it to the
Specified Lender of a purchase price agreed by it and the Specified Lender (or,
if they are unable to agree, a purchase price equal to the amount of the
Specified Lender's Pro Rata Share of the Loan and all other amounts then owed by
the Borrower to the Specified Lender). Upon consummation of such assignment, the
Replacement Lender shall become a party to this Agreement as a signatory hereto
and shall have all of the rights and obligations of the Specified Lender under
this Agreement and under the other Loan Documents, and no further consent or
action by any party shall be required. Upon the consummation of such assignment,
the Borrower, the Agent and the Specified Lender shall make appropriate
arrangements so that a new Revolving Credit Note is issued to the Replacement
Lender. The Borrower and the Guarantors shall sign such documents and take such
other actions reasonably requested by the Replacement Lender or the Agent to
enable the Replacement Lender to share in the rights created by this Agreement
and the other Loan Documents. Until the consummation of an assignment in
accordance with the foregoing provisions of this Section 12.13, the Company
shall continue to pay to or for the benefit of the Specified Lender all amounts
which it is required to pay pursuant to this Agreement and the other Loan
Documents, as they become due and payable.

     Article XIII. Guarantors.

     Section 13.01 Guarantors. The obligations of the Borrower under the Loan
Documents shall be guaranteed jointly and severally by each of the Guarantors
pursuant to the Guaranties.

     ENTERED INTO the date first above written.

Nashville, Tennessee                                             $80,000,000.00
July ____, 1997


     FOR VALUE RECEIVED, SOFAMOR DANEK GROUP, INC., an Indiana corporation (the
"Borrower") promises and agrees to pay to the order of SUNTRUST BANK, NASHVILLE,
N.A. ("Lender") at the offices of SunTrust Bank, Nashville, N.A., as agent (the
"Agent"), in Nashville, Tennessee, or at such other place as may be designated

thereto (such credit agreement, as it may be amended, modified, extended and/or

     The terms and conditions of any prepayment of this Note shall be governed
by the Credit Agreement.

     The terms and conditions in connection with requesting an Advance by
Borrower and for making any Advances by Lender hereunder shall be governed by
the applicable provisions of the Credit Agreement.

     This Note shall be repaid as follows:

          (a) From the date hereof through the Maturity Date, Borrower shall pay
     to Lender accrued interest under this Note, as follows:

               (i) interest on all Advances bearing interest at the Base Rate
          Option, shall be paid in arrears by Borrower to Lender on the first
          Business Day of each calendar month;

               (ii) interest on all Advances bearing interest at the LIBOR
          Option with a one-month Interest Period shall be paid at the end of
          the applicable Interest Period;

               (iii) interest on all Advances bearing interest at the LIBOR
          Option with a two-month Interest Period shall be paid by Borrower to
          Lender at the end of the applicable Interest Period;

               (iv) interest on all Advances bearing interest at the LIBOR
          Option with a three-month Interest Period shall be paid by Borrower to
          Lender at the end of the applicable Interest Period; and

               (v) interest on all Advances bearing interest at the LIBOR Option
          with a six-month Interest Period shall be paid by Borrower to Lender
          ninety (90) days after such Advance and at the end of the applicable
          Interest Period.

          (b) This Note shall mature on July ___, 2000 (the "Maturity Date"), at
     which time all outstanding principal, accrued interest, and all unpaid fees
     or charges hereunder (if any) will be immediately due and payable.

          (c) Any other fees or other charges due under the Credit Agreement
     shall be payable as set forth therein, and if no payment date is specified
     in the Credit Agreement, such fees and/or charges shall be payable on
     demand.

     Notwithstanding any provision to the contrary, it is the intent of Lender,
Borrower and all parties liable on this Note, that neither Lender nor any
subsequent holder shall be entitled to receive, collect, reserve or apply, as
interest, any amount in excess of the maximum lawful rate of interest permitted
to be charged by applicable law or regulations, as amended or enacted from time
to time. In the event the Note calls for an interest payment that exceeds the
maximum lawful rate of interest then applicable, such interest shall not be
received, collected, charged or reserved until such time as that




                                      -57-

interest, together with all other interest then payable, falls within the then
applicable maximum lawful rate of interest. In the event Lender, or any
subsequent holder, receives any such interest in excess of the then maximum
lawful rate of interest, such amount which would be excessive interest shall be
deemed a partial prepayment of principal and treated hereunder as such, or, if
the principal indebtedness evidenced hereby is paid in full, any remaining
excess funds shall immediately be paid to Borrower. In determining whether or
not the interest paid or payable, under any specific contingency, exceeds the
maximum lawful rate of interest, Borrower and Lender shall, to the maximum
extent permitted under applicable law, (a) exclude voluntary prepayments and the
effects thereof, and (b) amortize, prorate, allocate and spread, in equal parts,
the total amount of interest throughout the entire term of the indebtedness;
provided that if the indebtedness is paid in full prior to the end of the full
contemplated term hereof, and if the interest received for the actual period of
existence hereof exceeds the maximum lawful rate of interest, the holder of the
Note shall refund to Borrower the amount of such excess or credit the amount of
such excess against the principal portion of the indebtedness as of the date it
was received, and, in such event, Lender shall not be subject to any penalties
provided by any laws for contracting for, charging, reserving, collecting or
receiving interest in excess of the maximum lawful rate of interest.

     In the event that there occurs any Event of Default under the Credit
Agreement (any such event constituting an Event of Default under this Note),
then, in such event, at the option of the Majority Lenders or automatically in
the case of Events of Default under Sections 8.01(e) and 8.01(f) of the Credit
Agreement, as evidenced by notice from the Agent, the entire indebtedness hereby
evidenced shall become due, payable and collectible then or thereafter, without
further notice, as the holder may elect regardless of the date of maturity. The
Majority Lenders, evidenced by notice from the Agent, may waive any Event of
Default before or after the same has been declared and restore this Note to full
force and effect without impairing any rights hereunder, such right of waiver
being a continuing one.

     Following the occurrence of an Event of Default, principal and unpaid
interest bear interest at the Default Rate, until paid. The undersigned will pay
all costs and expenses in connection with the collection, enforcement,
protection and/or litigation with regard to this Note and/or any of Lender's
rights hereunder, including without limitation reasonable attorneys' fees.

     The makers, endorsers, guarantors and all parties to this Note and all who
may become liable for same, jointly and severally waive presentment for payment,
protest, notice of protest, notice of nonpayment of this Note, demand and all
legal diligence in enforcing collection, and hereby expressly agree that the
lawful owner or holder of this Note may defer or postpone collection of the
whole or any part thereof, either principal and/or interest, or may extend or
renew the whole or any part thereof, either principal and/or interest, or may
accept additional collateral or security for the payment of this Note, or may
release the whole or any part of any collateral security and/or liens given to
secure the payment of this Note, or may release from liability on account of
this Note any one or more of the makers, endorsers, guarantors and/or other
parties thereto, all without notice to them or any of them; and such deferment,
postponement, renewal, extension, acceptance of additional collateral or
security and/or release shall not in any way affect or change the obligation of
any such maker, endorser, guarantor or other party to this Note, or of any who
may become liable for the payment thereof.

effects thereof, and (b) amortize, prorate, allocate and spread, in equal parts,
the total amount of interest throughout the entire term of the indebtedness;
provided that if the indebtedness is paid in full prior to the end of the full
contemplated term hereof, and if the interest received for the actual period of
existence hereof exceeds the maximum lawful rate of interest, the holder of the
Note shall refund to Borrower the amount of such excess or credit the amount of
such excess against the principal portion of the indebtedness as of the date it
was received, and, in such event, Lender shall not be subject to any penalties
provided by any laws for contracting for, charging, reserving, collecting or
receiving interest in excess of the maximum lawful rate of interest.

     In the event that there occurs any Event of Default under the Credit
Agreement (any such event constituting an Event of Default under this Note),
then, in such event, at the option of the Majority Lenders or automatically in
the case of Events of Default under Sections 8.01(e) and 8.01(f) of the Credit
Agreement, as evidenced by notice from the Agent, the entire indebtedness hereby
evidenced shall become due, payable and collectible then or thereafter, without
further notice, as the holder may elect regardless of the date of maturity. The
Majority Lenders, evidenced by notice from the Agent, may waive any Event of
Default before or after the same has been declared and restore this

interest bear interest at the Default Rate, until paid. The undersigned will pay
all costs and expenses in connection with the collection, enforcement,
protection and/or litigation with regard to this Note and/or any of Lender's

may become liable for the payment thereof.

occasion.

credit held by Swing Line Lender on deposit for the account of Borrower or any

or 8.01(f) under the Credit Agreement, all unpaid amounts advanced hereunder and
interest thereon may be accelerated and become due in accordance with the Credit
Agreement regardless of the due date of any Advance made hereunder. Swing Line
Lender may waive any default before or after the same has been declared and
restore this Swing Line Note to full force and effect without impairing any of
Swing Line Lender's rights hereunder, such right of waiver being a continuing
one.

interest shall bear interest at the rate that is equal to the Default Rate,
until paid. The undersigned will pay all costs and expenses in connection with
the collection, enforcement, protection and/or litigation with regard to this
Swing Line Note and/or any of Swing Line Lender's rights hereunder, including

                                Form of Guaranty


                                    GUARANTY

     THIS GUARANTY ("Guaranty") is executed this ______ day of July, 1997 by 
_________________________, a [corporation] ("Guarantor"), in favor of SUNTRUST 
BANK, NASHVILLE, N.A., as Agent for the Lenders defined below (the "Agent").

     A. To induce Lender to extend credit to SOFAMOR DANEK GROUP, INC.
("Borrower") under that certain Credit Agreement executed by and among the
Agent, the Borrower and the Lenders listed or referred to therein (the
"Lenders") dated July ___, 1997 (as such credit agreement may be amended or
restated from time to time, the "Credit Agreement") and certain instruments,
agreements and documents executed or delivered in connection therewith (as
defined in the Credit Agreement, the "Loan Documents"), the Agent previously
required that Guarantor unconditionally guarantee the obligations of Borrower
under the Credit Agreement and the Loan Documents.

     NOW, THEREFORE, for other good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, Guarantor hereby agrees as follows:

     SECTION 1. DEFINED TERMS. Terms not defined in this Guaranty shall have the
meanings ascribed to such terms in the Credit Agreement.

     SECTION 2. INDEBTEDNESS DEFINED. The term "Indebtedness," as used herein,
shall mean any and all indebtedness, obligations and amounts of any kind and
character whatsoever owed by Borrower to Agent and/or Lenders at any time and
from time to time, whether now existing or later arising, including without
limitation all obligations and indebtedness evidenced by the Revolving Credit
Notes, the Foreign Currency Notes, any Letters of Credit and the Swing Line Note
executed by Borrower (or issued on behalf of Borrower with respect to Letters of
Credit) to Lenders pursuant to the Credit Agreement, together with any and all
extensions, renewals, amendments, modifications, restatements, replacements and
substitutions therefor (collectively, the "Notes"), the Credit Agreement and/or
the other Loan Documents, and any fees, expenses, and/or costs (including
without limitation attorneys' fees) incurred by Agent or Lenders in collecting
any of such indebtedness, whether from Borrower, Guarantor, or from any other
guarantor or other person or entity at any time liable for any of the
Indebtedness (an "Obligor") or any of the properties, rights or assets (if any)
securing the Indebtedness at any time, whether owned by Borrower, Guarantor, any
Obligor or any other person or entity (the "Collateral"), or in protecting any
of Agent's or Lenders' rights with respect to such indebtedness, Borrower,
Guarantor, any Obligor or any Collateral.

     SECTION 3. GUARANTY OF PAYMENT. Guarantor hereby unconditionally and
irrevocably


                                      -71-


<PAGE>   77

guarantees the timely payment and performance of the Indebtedness as and when
due. This Guaranty shall remain in full force and effect until full and final
payment, discharge and termination of the Indebtedness.

     SECTION 4. GUARANTY UNCONDITIONAL. Guarantor's guaranty of the Indebtedness
is continuing, absolute and unconditional. Without limiting the foregoing, the
validity of this Guaranty and Guarantor's obligations hereunder shall not be
impaired by any event, including without limitation any of the following,
whether or not Guarantor has any notice thereof: (a) the invalidity or
unenforceability of any agreement or instrument evidencing or relating to the
Indebtedness; (b) any present or future law, order or regulation of any
governmental authority purporting to reduce or affect the Indebtedness or any
person or entity liable for the Indebtedness or any Collateral; (c) any claim of
immunity, defense, set-off or counterclaim (other than full and final payment of
the Indebtedness) on behalf of any person or entity; (d) any change in the time,
place or manner of payment or performance, or any release, waiver, compromise,
settlement, increase, decrease, extension, renewal, acceleration, impairment or
termination (voluntary or otherwise) with respect to any or all of the
Indebtedness; (e) any release, addition, exchange, waiver, indulgence,
compromise, or settlement with respect to the Borrower, any Obligor or any
Collateral, or any failure to take, perfect or protect any lien or interest
intended as Collateral; (f) any modification, amendment, restatement or
replacement (in whole or in part) of any agreements or instruments evidencing,
comprising, securing, guarantying or otherwise relating to, executed or
delivered in connection with the Indebtedness; (g) any failure by Agent or the
Lenders to exercise diligence in the collection of the Indebtedness or any
action, omission or delay on the part of the Agent or the Lender or any other
person or entity to assert or enforce any claim, demand, right, power or remedy
referred to, conferred in or arising under this Guaranty or any of the other
agreements evidencing or relating to the Indebtedness; (h) the failure of any
other person or entity to guarantee or grant a lien or security interest as
collateral for any or all of the Indebtedness; (i) the voluntary or involuntary
liquidation, sale, cessation of business, marshalling of assets, receivership,
or financial decline of Borrower, or any insolvency, bankruptcy, assignment for
the benefit of creditors, reorganization or other similar proceedings affecting
the Borrower or its assets; (j) the merger, consolidation or dissolution of
Borrower or a change in Borrower's form, business, operations or management;
and/or (k) the absence of any notice to Guarantor of any default or breach under
this Guaranty or in connection with the Indebtedness, any acceleration of any of
the Indebtedness, the foreclosure or sale of any Collateral.

     SECTION 5. PRIMARY LIABILITY. This Guaranty constitutes a guarantee of
payment and performance and not of collection. Agent and/or Lenders may enforce
this Guaranty against Guarantor without first making demand on Borrower or any
other person or entity, or taking action against any Collateral, or instituting
collection proceedings upon the Indebtedness. Guarantor's liability for the
Indebtedness is primary, not secondary, and is joint and several with all
Obligors. Guarantor shall not be entitled to satisfy this Guaranty by
contributing ratably with any Obligor or otherwise paying less than the entire
unpaid Indebtedness. If any event occurs that would allow Agent and/or the
Lenders to accelerate any or all of the Indebtedness, but such acceleration as
to Borrower is prevented by law or otherwise, Guarantor agrees that for purposes
of this Guaranty the Indebtedness shall be deemed accelerated, and Guarantor
shall make 




                                      -72-

<PAGE>   78

payment on demand to Agent as required hereunder.

     SECTION 6. RECOVERY OF AVOIDED PAYMENTS. If any amount applied by Agent and
the Lenders to the Indebtedness is subsequently challenged by a bankruptcy
trustee or debtor-in-possession as an avoidable transfer on the grounds that the
payment constituted a preferential payment or a fraudulent conveyance under
state law or the Bankruptcy Code or any successor statute thereto or on any
other grounds, the Agent and/or the Lenders may, at their option and in their
sole discretion, elect whether and to what extent to contest such challenge. If
the Agent and/or the Lenders contest the avoidance action, all costs of the
proceeding, including the Agent's and/or the Lenders' attorneys' fees, will
become part of the Indebtedness. If any of the contested amounts are
successfully avoided (whether through settlement or otherwise), the avoided

of diligence on the part of Lender in collecting the Indebtedness or in taking,
perfecting, protecting or proceeding against the Collateral; (d) any right of
notice or consent, including without limitation notice of or consent to (i) any

     exceed one year. Average maturity will not exceed 180 days.
