                                     PART I


Item 1.       Business

OVERVIEW

         The Company is the leading publicly held regional wholesale distributor
of pharmaceutical and related healthcare and beauty aid products in the United
States. It serves more than 900 retail and institutional customers in 24 states
primarily in the Midwest and South. The Company also offers a variety of
value-added services to its customers, particularly in the areas of cost
containment and inventory management. The Company had net sales of $815.3
million in fiscal 1999, of which 47% were to independent pharmacies, 26% were to
retail chains, including national pharmacy chains and the pharmacy departments
of supermarkets and mass merchandisers, and 27% were to healthcare institutions,
including hospitals, alternate site care facilities, pharmacy benefit management
companies and managed care organizations. The Company operates from highly
efficient and cost effective distribution facilities in Cape Girardeau,
Missouri; Lexington, Kentucky; Minneapolis, Minnesota; as well as from
facilities in Aberdeen and Sioux Falls, South Dakota, resulting from the Jewett
Drug Co. ("Jewett") acquisition. On June 1, 1999, the Company consummated the
acquisition of 100% of the outstanding stock of Jewett, a pharmaceutical
distribution company based in Aberdeen, South Dakota that provides comprehensive
pharmaceutical distribution services to over 250 customers in the Upper Midwest
and Great Plains region. The aggregate purchase price for this acquisition of
$34.3 million consisted of $21.5 million in cash and $12.8 million (555,556
shares) of the Company's common stock.

         Since its formation in 1987, the Company has expanded the scope and
breadth of its business by consistently providing the highest levels of service
to its customers and suppliers. The Company achieves such high levels of service
by (i) providing its customers with a full continuum of products, value-added
services and support, which enable its customers to compete more effectively;
(ii) focusing on flexibility, which allows the Company to respond quickly to
change and to customize systems to meet its customers' and suppliers'
requirements; (iii) strategically locating the Company's distribution centers
and satellite transfer depots throughout the Midwest and the South, which
enables the Company to ship products to and service its customers promptly and
efficiently; and (iv) attracting and motivating experienced and entrepreneurial
management personnel, who continually seek to improve and expand the Company's
business.

          In 1996, management of the Company initiated a plan to reposition the
Company and significantly improve operating performance. This plan included: (i)
identifying and focusing the Company's efforts on high-growth niche markets;
(ii) centralizing certain management functions, including purchasing, marketing
and information systems at its corporate offices, while decentralizing
executive, sales and operating functions at each of its independently managed
profit centers, including its three regional distribution centers; (iii)
enhancing the depth and breadth of the Company's management team; (iv) creating
new management and employee incentive plans; (v) upgrading the Company's
facilities; and (vi) enhancing the Company's corporate image. Since implementing
these strategic initiatives, net sales and net income have grown in each of the
last 13 fiscal quarters compared to the same periods in the prior years.

         The Company believes that its regional-market focus and high level of
customer service provide it with competitive advantages and position it to
benefit from trends impacting the industry. Management believes that the
increasing size of the wholesale pharmaceutical industry's larger national
participants hampers the ability of these companies to deliver customized
services to most of their customers. The Company has successfully differentiated
itself from its national competitors through its ability to provide flexible and
customized services to its targeted customer segments. The Company has
demonstrated its ability to work with customers to eliminate waste from the
supply chain. In addition, healthcare providers' need for value-added services
which help contain costs and effectively manage inventory has given the Company
the opportunity to capitalize on its cost competitiveness and advanced systems.
The location and quality of the Company's distribution facilities and satellite
transfer depots in the Midwest and South allow the Company to service its
customers' and suppliers' needs promptly and efficiently. The Company has
capitalized on the increased demand for alternate care providers through its
investment in Pharmaceutical Buyers, Inc. ("PBI") in fiscal 1996. PBI is one of
the nation's leading alternate site group purchasing organizations, and the
Company's investment in PBI provides it with access to a higher margin business
segment and insight into alternate site distribution.

         The wholesale pharmaceutical distribution industry has experienced
rapid sales growth over the past 12 years, increasing from approximately $14.0
billion in sales in 1985 to more than $77.4 billion in 1998. The Company
believes that there are several major trends currently affecting the industry,
including: (i) continued consolidation of national and regional wholesale drug
distribution companies; (ii) an increasing emphasis on value-added services that
lower healthcare providers' administrative and other costs associated with
medical supply management; (iii) the growing importance of an efficient
distribution model as customers become more cost conscious; and (iv) a shift in
the delivery of healthcare services from acute care settings to alternate sites,
including physician offices and extended care facilities. In addition, the aging
population, the increase in research and development spending by pharmaceutical
manufacturers and an increase in direct-to-consumer advertising are all
positively impacting pharmaceutical demand.


PRODUCTS, SERVICES AND VALUE ADDED MARKETING SYSTEMS

         The Company's product line consists of more than 25,000 SKUs (stock
keeping units), including branded pharmaceuticals, multi-source generics,
private label products, repackaged pharmaceutical products and over-the counter
health and beauty aids. The Company sells branded pharmaceuticals (approximately
90% of net sales in fiscal 1999), generic pharmaceuticals (approximately 5.0% of
net sales in fiscal 1999) and over-the-counter health and beauty aids
(approximately 5.0% of net sales in fiscal 1999). In addition, through its
Tykon, Inc. subsidiary (acquired September 1998), the Company developed and
markets a proprietary PC based order entry/order confirmation system to the drug
distribution industry.

         The Company strives to offer services which enhance the operating
efficiencies of its customers and assist them in competing effectively.
Principal elements in the Company's service offerings to its customers include:
(i) RESOURCESM, a proprietary PC based order entry/order confirmation system
that completely automates all order creation, transmission and confirmation
operations; (ii) PARTNERSSM, a fully automated and customizable replenishment
software system which helps pharmacies more efficiently coordinate product
supply and demand; (iii) RESOURCE HQSM, a contract management and reporting
software system designed for group purchasing and managed care organizations,
and retail chains which automates functions relating to corporate and group
contracts; and (iv) SCRIPTMASTER(R), a pharmacy management software system that
provides prescription management functions, drug and allergy checks,
instantaneous connections to hundreds of third party insurance plans, "just in
time" inventory management, automated accounts receivable, quick pay program
monitoring and central office functions.

         The Company offers a broad range of merchandising and marketing
services to its independent pharmacy customers under its MedPlus(R) identity
program. Under this program, the Company plans and coordinates cooperative
advertising programs and provides for the availability of various promotional
products, including a single-source supply for generics at highly competitive
prices from leading pharmaceutical manufacturers. The Company also offers new
product introduction programs, point-of-sale materials, calendars, blood
pressure testing units, automatic new product distribution, rack jobbing, store
fixturing and retail employee training programs. Other services offered to
independent pharmacies under Med Plus include: retail merchandising, inventory
management systems, electronic order entry, planogramming, shelf labels and
price stickers, private label products, monthly feature promotions, home
healthcare marketing programs, store layout assistance, business management
reports, pharmacy computer systems and monthly catalogs.


CUSTOMERS AND MARKETS

         The Company's diverse customer base consists of over 900 independent
pharmacies, retail chains and healthcare institutions. Independent pharmacies
generally are community-based pharmacies, which the Company believes benefit the
most from the Company's sales and value added services. Retail chains, a fast
growing segment of the market, include national pharmacy chains and the pharmacy
departments of supermarkets and mass merchandisers. Healthcare institutions,
which currently comprise the largest segment of the market, consist of
hospitals, nursing homes, clinics and other alternate site care facilities, home
health agencies, HMOs and pharmacy benefit management companies.






                                       3

<PAGE>   4


         The independent pharmacy trade class stabilized in 1998 with store
closings dropping to 121 from 1,118 in 1997. In addition, the Company has worked
with entrepreneurs to open new independent community pharmacies. This could
present additional opportunities as the Company is well positioned to respond to
the needs of new pharmacies requiring a flexible, innovative trading partner.

         The Company believes that diversifying its sales across the various
market segments enables it to capture greater market share in the geographic
areas it serves and better serve the faster growing segments of the healthcare
markets. The following table sets forth the Company's sales mix by customer
segment:

</TABLE>

         The Company's senior management is actively involved in identifying and
developing opportunities to expand the Company's business with customers in each
of these market segments, including the preparation of proposals which highlight
customer benefits of the Company's cost competitiveness, advanced systems and
value added services. During fiscal 1997, fiscal 1998 and fiscal 1999, the
Company's 10 largest customers accounted for approximately 47.1%, 37.1% and
52.8%, respectively, of the Company's revenues. The Company's largest customer
during fiscal 1997 (with which the Company's relationship was terminated in
September 1997) accounted for approximately 20.0% of the Company's revenues
during that year and Anthem Prescription Management, Inc., its largest customer
during fiscal 1998 and fiscal 1999, accounted for approximately 13% and 12% of
the Company's revenues during those periods, respectively.

         In fiscal 1999, the increase in percentage sales to the 10 largest
customers resulted from a focused marketing effort directed towards large
national chains. Jewett's largest customer, Tel Drug (the mail order division
of CIGNA) accounted for 54.0% and 66.0% of Jewett's sales in calendar 1997 and
1998, respectively. Tel Drug is expected to be the Company's largest customer
in fiscal 2000.

         In September 1999, the Company renewed its primary supplier contract
with the Tennessee Pharmacy Coalition/Tennessee Pharmacy Purchasing Alliance
("TPPA") extending the agreement through August 2002. TPPA is a group purchasing
alliance which currently has over 180 members of independent pharmacies
operating in Tennessee, Ohio, Georgia, Virginia, Arkansas, Mississippi and
Alabama. Over the next three years, the agreement is expected to represent in
excess of $400 million of pharmaceutical sales; however, TPPA members each
control their own purchasing and, as such, do not comprise one of the Company's
largest customers.

SALES AND MARKETING

         The Company recently reinforced its corporate sales effort by promoting
two executives to the position of Vice President - Business Development who will
focus on high potential new customer prospects.

         The Company employs sales representatives and customer service
representatives at each of its distribution centers. In addition to base salary,
the Company's sales personnel receive incentive compensation based upon
increases in the Company's market share and market penetration. D&K's corporate
vice presidents of business development work closely with each business unit to
develop sales goals. The Company's sales program includes regular training to
improve customer service and to provide its sales and customer service
representatives with the skills and resources necessary to increase business
with existing customers and establish new customer relationships. The Company
also maintains a telephone service department staffed with trained personnel who
work with customers to answer questions and solve problems.





                                       4

<PAGE>   5

         The Company's marketing efforts are focused on developing new primary
relationships with its customers. The Company emphasizes frequent personal
interaction of its sales force with customers so that the customer comes to rely
on the Company's dependability, responsiveness, accuracy of order filling and
breadth of product line. Retail customers also rely on the Company's sales force
for consulting services on advertising, merchandising, stocking and inventory
management.

         The Company believes that its customer service department is a key
element in its marketing program and differentiates it from its national
competitors. The decentralized customer service staff emphasizes rapid response
to customer inquiries and efficient order placement.

OPERATIONS

         The Company is structured as an organization of locally managed drug
wholesale distribution centers. Each distribution center has an executive, sales
and operations staff with management compensation at each center determined by
its operating results. These operations utilize the Company's corporate staff
for procurement, marketing, financial, legal and executive management resources
and corporate coordination of assets and working capital management. The
Company's decentralized sales and distribution network, combined with its
centralized procurement and corporate support staff structure, enable the
Company to provide high levels of specialized, customer service while minimizing
administrative expenses and maximizing volume discounts for product purchases.

         The Company's distribution centers maintain computer systems and
sophisticated materials handling equipment for receiving, storing and
distributing large quantities and varieties of products. The Company
continuously seeks to improve its warehouse automation technologies to maximize
operational efficiencies on a cost-effective basis. The Company developed state
of-the-art radio frequency (RF) and receiving procedures and barcoding and
scanning technologies at one of its distribution centers which significantly
improved accuracy, efficiency and productivity at that center. The Company
subsequently exported this technology to its other distribution centers and has
developed RF order verification, vendor returns and customer returns systems.

         The Company receives virtually 100% of its orders electronically and,
upon receipt of the customer's order at a distribution center, the Company's
warehouse-management system produces a "picking document" containing product
selection, loading and truck routing information. The system also provides
customized price information (geared to local market as determined by the
customer) or individual package price stickers to accompany each shipment to
facilitate the customer's pricing of the items. Virtually all items ordered from
the Company's distribution centers are available and shipped by the Company
within 24 hours after the orders are placed by customers. Orders are delivered
to customers by the Company's fleet of trucks and vans or by contract carriers.

PURCHASING AND INVENTORY CONTROL

         The Company utilizes sophisticated inventory-control and purchasing
software. The software perpetually tracks the Company's inventory, analyzes
demand history and projects future demand. The Company's system is designed to
enhance profit margins by eliminating the manual ordering process, allowing for
automatic inventory replenishment and identifying inventory buying
opportunities. The system also improves the Company's fill rate and enhances
inventory management and control.

         The Company purchases products from approximately 1,000 manufacturers
for the wholesale purchase of pharmaceuticals and other products. The Company
initiates purchase orders with manufacturers through its information systems.
During fiscal 1998 and fiscal 1999, the Company's 10 largest suppliers accounted
for approximately 62% and 47%, respectively, of the Company's purchases by
dollar volume. Historically, the Company has not experienced difficulty in
purchasing desired products from suppliers. The majority of contracts with
suppliers are terminable by either party upon short notice and without penalty.
The Company believes that its relationships with its suppliers are good.

<PAGE>   6


MANAGEMENT INFORMATION SYSTEMS

         Each of the Company's distribution centers operates as a distinct
business with full systems functionality: order processing, inventory
management, accounts receivable, accounts payable, general ledger, master file
maintenance, external and internal reporting. Historically, each distribution
center housed an AS/400 system and several PCs, and the St. Louis corporate
office housed an additional AS/400 to support corporate systems. The Company is
in the process of consolidating AS/400 computer processing into two major data
centers: St. Louis and Cape Girardeau. These two data centers will provide
computing services to support all distribution centers as well as corporate
functions. Implementation of high availability business continuity systems to
support continuous operation of the consolidated data centers is planned for the
coming fiscal year. Each distribution center and the corporate offices will
continue to house a local area network (LAN) and multiple PCs. The Company's
computer systems are connected by a high speed data network and information is
transmitted between locations on a regular basis. The Company is standardizing
e-mail systems with implementation of a central e-mail server.


COMPETITION

         The wholesale distribution of pharmaceuticals, health and beauty aids,
and other healthcare products is highly competitive, with national and regional
distributors competing primarily on the basis of service and price. Other
competitive factors include delivery service, credit terms, breadth of product
line, customer support, merchandising and marketing programs. The Company
competes with large, national distributors such as McKesson HBOC, Inc., Bergen
Brunswig Corporation, Cardinal Health, Inc., Bindley-Western Industries, Inc.
and AmeriSource Health Corporation, as well as with local and regional
wholesalers, manufacturers and generic pharmaceutical telemarketers and
specialty distributors. The Company also competes with other wholesale
distributors for purchases of products and financial support in the form of
trade credit from manufacturers. Certain of the Company's competitors have
significantly greater financial and marketing resources than the Company.


EMPLOYEES

         As of August 31, 1999, the Company employed 324 persons, 290 of whom
were full-time employees. Approximately 23 of the Company's employees at its
Minneapolis, Minnesota distribution center are covered by a collective
bargaining agreement with the Miscellaneous Drivers, Helpers and Warehousemen's
Union, Local 638, which expires in March 2000. Approximately 15 of the Company's
employees at its Jewett Drug Co. subsidiary are covered by a collective
bargaining agreement with the General Drivers and Helpers Union Local 749,
affiliated with the International Brotherhood of Teamsters, which expires
February 29, 2000. The Company believes that its employee relations are good.

              (1) Special Shipments. All shipments of (a) Product deferred from
                  previous orders; (b) Products that are newly released for
                  Wholesaler stocks (initial shipment and all reorders for first
                  thirty (30) days after release date); and (c) allocated
                  shipments; 100%

              (2) Regular Shipments. Shipments, other than Special Shipments, as
                  listed in Section E.I.a.(I), covered by the first two orders

          A.  Shipments on Third-Party. Orders for Products not released to
              Wholesalers; 50%

       2. TRANSPORTATION SELECTED BY WHOLESALER. If the Wholesaler requests
          special routing of a shipment which results in a higher transportation
          Cost than would be incurred as a result of the routing of Lilly's
          selection, then the extra cost shall be added to the invoice.

       3. TITLE AND RISK OF LOSS. Title and risk of loss shall pass to the
          Wholesaler when the Products are duly delivered to the carrier. The
          Wholesaler shall give Lilly written notice of any claimed shipping
          error within thirty (30) days after the date of shipment from Lilly.
          Failure of the Wholesaler to give such notice within such 30-day
          period shall be deemed a waiver of the Wholesaler's claim for
          shortages or incorrect shipments.

       4. CONCEALED DAMAGE. Damage to Products in course of shipment from Lilly
          but not discovered on receipt is considered concealed damage and
          must be reported to a Lilly Customer Services Representative within
          thirty (30) days of receipt for credit to be issued.

    F. RETURN FOR CREDIT. To receive from the Wholesaler, or through a company

       4. Products damaged while in the Wholesaler's possession are
          non-returnable.

       5. Products damaged while in transit from Lilly to the Wholesaler should

          quality and security of the product. The damaged product should be
          returned at Lilly's expense to the point of shipment. Lilly Customer
          Services must be contacted to make appropriate arrangements.

       6. Items damaged from such perils as are normally insured under the
          standard fire insurance policy, including extended coverage,
          vandalism, and malicious mischief, will not be reimbursed by Lilly.

       7. Returns of parts of sales packages, returns from customers of the
          Wholesaler, and any other returns not authorized by this return goods
          policy will be destroyed with no credit issued.

          application of Credit Memorandum, by means of an electronic funds
          transfer ("EFT") system designated or approved by Lilly in its
          discretion, as follows:

          a. Funds shall be transferred at the direction of the Wholesaler and

             of the invoice:

             2% 32, NET 45

             100% of gross invoice due on or by the forty-fifth (45th)day from
             date of invoice.

          b. The Wholesaler warrants to Lilly that each entry transmitted by it
             or its agents or employees on its behalf to a depository financial
             institution for the purpose of initiating an EFT transaction is
             duly authorized by the Wholesaler. Without the Wholesaler's prior
             written consent, Lilly shall not have the right to debit
             electronically any account of the Wholesaler.

          c. The Wholesaler shall not be deemed in default or lose any cash
             discount by reason of any delay in receipt or non-receipt by Lilly
             of funds transferred by EFT unless the delay or non-receipt is the
             result of the negligent or willful act or omission of the
             Wholesaler.

          d. Credits approved in accordance with this Agreement or with the
             Lilly Chargeback Manual, as applicable, shall be paid to the
             Wholesaler by Lilly, following Lilly's approval of the credit by
             means of an EFT system established by Lilly and in a manner
             consistent with the Lilly Chargeback Manual.

          e. With respect to any EFT entry originated by Lilly's bank, or any
             delay in receipt by the Wholesaler of approved credit funds
             transmitted by Lilly by means of EFT, Lilly shall be liable to the
             Wholesaler only for Lilly's or Lilly's bank's negligent acts or
             omissions or failure to act in good faith and Lilly's liability to
             the Wholesaler shall be limited to reasonably foreseeable actual
             damages proximately caused thereby.

          f. With respect to the use of EFT by the Wholesaler for the payment of
             funds, the Wholesaler shall be liable to Lilly only for the
             Wholesaler's negligent acts or omissions or failure to act in good
             faith and the Wholesaler's liability to Lilly shall be limited to
             reasonably foreseeable actual and direct damages caused thereby,
             but excluding any consequential, incidental or indirect damages.

          g. Except as provided in Sections III.B.2.e and f., neither party
             shall be liable to the other for the act or omission of any
             financial institution or any automated clearing house in connection
             with the use of EFT for payment of funds and neither party shall be
             liable for consequential damages to the other arising out of the
             use of EFT for payment of funds.

          h. Each party agrees promptly to return by EFT any overpayment
             received by it.

          i. The Wholesaler agrees to execute all authorizations required by
             Lilly or Lilly's or Wholesaler's depository financial institutions
             for payment and receipt of funds by EFT and to notify Lilly
             promptly of any changes in those authorizations.

          j. To the extent applicable to the transfer of funds by EFT under this
             Agreement, each party agrees to be bound by the Operating Rules and
             Guidelines of the National Automated Clearing House Association as
             those Operating Rules and Guidelines may be in effect from time to
             time.

       3. Lilly may require that each order from the Wholesaler be accompanied
          by a certified check or other form of payment satisfactory to Lilly in
          an amount sufficient to cover the order less the current cash discount
          (if any) or require that the Wholesaler provide security in an amount
          and form satisfactory to Lilly, and may declare due and owing all
          outstanding indebtedness from the Wholesaler, including invoices on
          which extended dating has been granted, in the event (a) reasonable
          grounds for insecurity arise with respect to the performance by the
          Wholesaler under this Agreement or (b) the Wholesaler makes or gives
          notice of its intention to make a bulk transfer of inventory or (c)
          Lilly has given notice of termination of this Agreement or (d) the

          except the provisions of Section III.B.2.f.

    C. INSPECTION OF INVENTORY AND RECORDS. A Lilly representative will consult
       with and advise the Wholesaler concerning the Wholesaler's inventory of
       Products and may inspect the same at a mutually agreed upon time. A Lilly
       representative may also inspect records of the Wholesaler to determine
       compliance with the Wholesaler's obligations under this Agreement
       provided that no such inspection shall relate to transactions occurring
       more than eighteen (18) months prior to the date of such inspection, and
       provided further that the inspection shall be performed by Lilly's
       regularly retained independent auditors or employee.

    D. INDEMNIFICATION. Lilly shall indemnify and hold harmless Wholesaler and
       its affiliates, sublicensors, officers, directors, employees and agents

       including court costs and reasonable attorneys fees (collectively
       "Claims") arising out of injury or death to person or property alleged to
       have resulted from Lilly's manufacturing of the Products except to the
       extent caused by the negligent acts or omissions, or willful misconduct
       of Wholesaler, its affiliates, sublicensors, officers, directors,
       employees and agents or by the Wholesaler's breach of its obligations
       under this Agreement. Wholesaler shall indemnify and hold harmless Lilly
       and its affiliates, sublicensors,

       arising from the handling, storage, repackaging, sale or distribution of
       the Products by Wholesaler, its affiliates, sublicensors, officers,
       employees and agents, except to the extent caused by the negligent acts
       or omissions of Lilly.

    E. NO EXCLUSIVE TERRITORY. This Agreement does not grant the Wholesaler
       any exclusive rights in any territory.

    F. BUYER-SELLER RELATIONSHIP. The relationship created by this Agreement is
       a buyer-seller relationship and not an agency relationship.

    G. CHANGE IN OWNERSHIP OF OR CONTROLLING INTEREST IN WHOLESALER OR ANY
       SUBSIDIARY, AFFILIATE OR LOCATION. The Wholesaler shall give Lilly at
       Indianapolis, Indiana, ten (10) days prior notice of the sale or other
       transfer of substantially all of the assets of or a controlling  interest
       in the Wholesaler, or the sale or other transfer of substantially all of
       the assets of or a controlling interest in any of the subsidiaries,
       affiliates or locations specified in Schedule A.

    H. REPURCHASE OF STOCK. Upon cancellation or termination of this Agreement,
       by expiration or otherwise, Lilly shall have the option to repurchase the
       Wholesaler's salable stock of Products at the Net Wholesale prices then
       in effect.

    I. ASSIGNMENT. Neither party shall assign its rights or obligations under
       this Agreement without first obtaining the written consent of the other
       party, and any attempted assignment without such written consent shall be
       void and of no effect.

    J. CONTINGENCIES AFFECTING PERFORMANCE. Neither party shall be liable for
       delay in performance or nonperformance caused by fire, flood, storm,
       earthquake, or other act of God, war, rebellion, riot, failure
       of carriers to furnish transportation, strikes, lockouts or other
       labor disturbances, act of governmental authority, inability to obtain
       material or equipment, or any other cause of like or different nature
       beyond the control of such party.

    K. NOTICES. All notices under this Agreement shall be in writing and shall
       be considered given when delivered or mailed postage prepaid by

       is given as set forth on the next page.

    L. TERMINATION OR CANCELLATION.

       1. This Agreement shall terminate on June 30, 2002, unless sooner

       3. This Agreement shall terminate as to all of the subsidiaries,
          affiliates or locations set forth in Schedule A at the time
          substantially all the assets of or a controlling interest in the
          Wholesaler is sold or otherwise transferred to a new owner, and shall
          terminate as to any of the subsidiaries, affiliates or locations
          specified in Schedule A at such time as the Wholesaler ceases to own
          substantially all of the assets of or a controlling interest in such
          subsidiary, affiliate or location unless otherwise provided for by
          Lilly in writing.

       4. Either party may cancel this Agreement, as to all or any one or more
          of the subsidiaries, affiliates or locations set forth on Schedule A,
          upon notice for breach by the other party of any covenant contained
          herein. Without limiting this right of cancellation by either party,
          any failure by the Wholesaler to comply fully with the provisions
          of Sections 1.E. (Registration with DEA), 1.F. (Compliance with
          Applicable Laws), and 1.G.2, (Chargeback Data) shall constitute a
          breach of this Agreement by the Wholesaler.

    M. NEW AGREEMENT. Lilly and the Wholesaler may enter into a new Agreement
       for the thirty-six (36) months following the expiration of this

       agreement. If the Wholesaler desires to enter into the new Agreement, it
       shall deliver or mail to Lilly at Indianapolis, Indiana, on or before the
       expiration date of the current agreement, both copies of the new
       Agreement executed by the Wholesaler. If Lilly agrees to the new
       Agreement, it shall execute the new Agreement and return one copy to the
       Wholesaler within 30 days of Lilly's receipt of the executed new
       Agreement.

    N. ENTIRE AGREEMENT. This Agreement shall (1) supersede all prior contracts,
       agreements, and understandings between the Wholesaler and Lilly,
       including any agreements between Dista Products Company, Division of Eli
       Lilly and Company, and the Wholesaler, relating to the subject matter
       hereof, all of which are hereby terminated; (2) constitute the complete
       agreement between the Wholesaler and Lilly, relating to the subject
       matter hereof; and (3) be controlling to the exclusion of all terms and
       conditions of the Wholesaler's purchase orders or other documents in
       conflict with the subject manner contained within this Agreement. This
       provision shall not be construed in a matter that prevents the execution,
       as appropriate, of any specialty wholesaler agreements between Lilly and
       any specialty wholesaler that may be an affiliate or subsidiary of the
       Wholesaler during the term of this Agreement.

    O. WAIVER. The failure of any party to enforce at any time any provision of
       this Agreement shall not be a waiver of such provision or effect the
       right of such party thereafter to enforce such provision. No waiver shall
       be deemed a waiver of any other provision or of a subsequent breach
       whether of the same or another provision.

    P. APPLICABILITY TO SUBSIDIARIES, AFFILIATES, OR LOCATIONS. Each covenant,
       right, and obligation of the Wholesaler contained in this Agreement shall
       apply separately and fully to each subsidiary, affiliate or location
       specified in Schedule A.

    Q. GOVERNING LAW. This Agreement shall be interpreted in accordance with,
       and governed by, the laws of the State of Indiana.

    R. YEAR 2000. Wholesaler represents and warrants that its operations
       including without limitation, the submission of chargeback data will not
       be materially delayed, interrupted or otherwise adversely affected due to
       either the failure of Wholesaler's business systems and/or computer
       systems to be "Year 2000 Compliant" or the failure of the computer or
       business systems of any third party on which the Wholesaler is dependent
       to be "Year 2000 Compliant". For purposes of this paragraph, a system
       shall be considered "Year 2000 Compliant" only if (i) the occurrence in
       or use by that system of dates on or after January 1, 2000 ("Millennial
       Dates") does not adversely affect that system's performance, including
       without limitation performance with respect to date-dependent data,
       computations, output, or other functions (including, without limitation,
       calculating, comparing, and sequencing), and (ii) that system creates,
       stores, processes and outputs information (as applicable) related to or
       including Millennial Dates without errors or omissions.

                 FIRST AMENDMENT TO FOURTH AMENDED AND RESTATED
                          LOAN AND SECURITY AGREEMENT

     THIS FIRST AMENDMENT TO THE FOURTH AMENDED AND RESTATED LOAN AND SECURITY
AGREEMENT (this "Amendment") is made as of November 25,1998, by and among FLEET
CAPITAL CORPORATION, a Rhode Island corporation (the "Lender"), and D&K
HEALTHCARE RESOURCES, INC. ("D & K") and JARON, INC. ("Jaron"), (D & K and Jaron
are sometimes hereinafter referred to individually as "Borrower" and
collectively as "Borrowers").

                             Preliminary Statements

     A.   Lender and Borrowers are parties to that certain Fourth Amended and
Restated Loan and Security Agreement dated as of August 7, 1998 (as amended, the
"Loan Agreement"). Capitalized terms used herein and not otherwise defined shall
have the meanings given them in the Loan Agreement.

     B.   Borrowers and Lender now desire to amend certain provisions of the
Loan Agreement on and subject to the terms hereof.

                               Terms of Agreement

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

     1 .  Amendment to Loan Agreement. The Loan Agreement is hereby amended by
deleting Section 1.2 [RELATING TO LETTERS OF CREDIT; LC GUARANTIES] in its
entirety and replacing it with the following new Section 1.2:

          "1.2 Letters of Credit; LC Guaranties. Lender agrees, for so long as
     no Default or Event of Default exists and if requested by D&K on its own
     behalf or as agent for any Borrower, to (i) issue its, or cause to be
     issued its Affiliate's, Letters of Credit for the account of any Borrower
     or (ii) execute LC Guaranties by which Lender or its Affiliate shall
     guaranty the payment or performance by any Borrower of its reimbursement
     obligations with respect to Letters of Credit and letters of credit issued
     for Borrower's account by other Persons in support of such Borrower's
     obligations (other than obligations for the repayment of Money Borrowed),
     provide that the LC Amount at any time shall not exceed $10,000,000. No
     Letter of Creditor or LC Guarantee may have an expiration date that is
     after the last day of the Original Term. Any amounts paid by Lender under
     any LC Guaranty or in connection with any Letter of Credit shall be treated
     as Revolving Credit Loans, shall be secured by all of the Collateral and

         any of its obligations hereunder and fails to cure such breach within
         ninety (90) days (fifteen (15) days for failure to make payments when
         due) after receipt of notice of such breach; and D & K may terminate
         this Agreement at any time if TPPA or its assets (whether voluntarily
         or involuntarily) become the subject of any bankruptcy or insolvency
         proceeding or if TPPA makes an assignment for the benefit of its

         Member's payment obligations) will be excused if and to the extent that
         any delay or failure to perform such obligation is due to acts of
         nature, governmental actions, strikes or labor disputes or other causes
         or situations beyond the reasonable control of that party.

20.      Confidentiality. Each party agrees to maintain in confidence the terms

       CURRENTLY IN USE TODAY BY INDEPENDENT PHARMACIES. D&K HAS HAD THIS FULLY

       PAST TWO YEARS. PARTNERS IS THE ONLY PROGRAM IN USE IN THE MARKET TODAY
       THAT IS FULLY AUTOMATED AND USES HISTORICAL DISPENSING/USAGE DATA TO

          4.   RENT.

               4.1  BASE RENT. Tenant shall pay to Landlord as base rent (the
"Base Rent") see Section 1 J/K in equal monthly installments throughout the term
of the Lease as provided in Section 1 K.

               4.2  ADDITIONAL RENT. All charges due and payable by Tenant other
than Base Rent are herein called "Additional Rent." The term "Rent" shall mean
Base Rent and Additional Rent.

               4.3  TIME AND MANNER OF PAYMENT. Payments of Rent are to be made
to BSRT LEXINGTON TRUST, care of Coleman Group Property Services, Dept. 77-6544.
Chicago, IL 60678-6544 or as Landlord shall hereafter designate. Rent shall be
due and payable in advance on the first (1st) day of each month, without
offset, deduction or demand, except That Any Partial Month Rent shall be
prorated. The burden of proof of full payment shall be upon Tenant. Upon any
termination of this Lease not resulting from Tenant's default, and after Tenant
has vacated the Premises as required herein, an equitable adjustment shall be
made as to all payments made by or due from Tenant.

               4.4  LATE CHARGES. Tenant's failure to pay Rent promptly may
cause Landlord to incur unanticipated costs. The amount of such costs are
difficult to ascertain, and therefore on any Rent payment not made within ten
(10) days after NOTICE TO TENANT THAT it is due, THEN Tenant shall pay Landlord
a late charge equal to fifteen percent (15%) of the overdue amount. The parties
agree that such late charge represents a fair and reasonable estimate of the
costs Landlord will incur by reason of such late payment.

               4.5  PROPORTIONATE SHARE. Tenant's "Proportionate Share" as used
in this Lease shall be obtained by multiplying the expense in question by a
fraction, the numerator of which shall be the square footage area of the
Premises and the denominator of which shall be the rentable square footage area
of the Building. If a particular expense is incurred or charged to more than one
building in the Project rather than solely to the Building, then, for the
purposes of calculating Tenant's Proportionate Share with respect the Building,
such multi-building expense shall be allocated to Building by multiplying the
expense in question by a fraction, the numerator of which shall be the rentable
square footage of the Building and the denominator of which shall be the
rentable square footage area of the buildings for which the expense was incurred
or otherwise allocated to, with the resulting number being used to calculate
Tenant's Proportionate Share as to the Premises. NOTWITHSTANDING ANYTHING IN
THIS LEASE TO THE CONTRARY, TENANT'S PROPORTIONATE SHARE OF COMMON EXPENSES AND
REAL PROPERTY TAXES AND INSURANCE RELATING TO TAXES, INSURANCE AND COMMON AREA
MAINTENANCE SHALL NOT EXCEED THE FOLLOWING AMOUNTS PER SQUARE FOOT DURING THE
TERM OF THIS LEASE:  YR.  1: $.50 P.S.F.

                   1.   DURING THE FIRST YEAR OF THE LEASE, LANDLORD, AT ITS
                        COST, SHALL BE RESPONSIBLE FOR ANY REPAIRS OR
                        REPLACEMENT TO HVAC EQUIPMENT NOT COVERED BY THE
                        MAINTENANCE CONTRACT.

                   2.   DURING YEARS 2-10 OF INITIAL LEASE TERM TENANT SHALL BE
                        RESPONSIBLE FOR FIRST $2,000.00 OF REPAIRS NOT COVERED
                        BY MAINTENANCE AGREEMENT AND LANDLORD SHALL BE
                        RESPONSIBLE FOR ALL EXPENSES ABOVE $2,000.00 THAT ARE
                        NOT COVERED BY THE MAINTENANCE AGREEMENT.

                   If Tenant fails to maintain and repair the Premises AS
PROVIDED IN THIS PARAGRAPH 11, Landlord may, on ten (10) days' prior notice
(except that no notice shall be required in case of emergency) enter the
Premises and perform such repair and maintenance on behalf of Tenant. In such
case, Tenant shall reimburse Landlord for all costs so incurred immediately upon
demand.

<PAGE>   16

              12. RIGHT OF ENTRY. Landlord, and its agents or other
representatives, shall have the right to enter into and upon the Premises or any
part thereof at all reasonable times for the purpose of examining the same, AND
AFTER REASONABLE NOTICE TO TENANT (EXCEPT IN EMERGENCIES) to make repairs or
alterations, or showing the Premises to prospective purchasers of the Building.
LANDLORD SHALL USE ITS BEST EFFORTS NOT TO DISTURB OR INTERFERE WITH TENANT'S
USE OF THE PREMISES WHILE LANDLORD PERFORMS ANY SUCH REPAIRS OR ALTERATIONS.
Tenant agrees at any time within six (6) calendar months before the expiration
of this Lease to allow Landlord to enter upon the Premises TO EXHIBIT IT TO
PROSPECTIVE TENANTS and will permit all persons authorized by Landlord to view
said Premises at reasonable times.

              13. UTILITIES. All heat, electric current, gas, garbage, or
utility charges of any nature used on the Premises shall be paid for by Tenant.
Landlord shall not be liable to Tenant for interruption in or curtailment of any
utility service, nor shall any such interruption or curtailment constitute a
constructive eviction or grounds for rental abatement in whole or in part.

              14. ASSIGNMENT AND SUBLETTING. No portion of the Premises or of
Tenant's interest in this Lease may be acquired by any other person or entity,
whether by assignment, mortgage, sublease, transfer, operation of law, or act of
Tenant or any change in controlling interest of Tenant, without Landlord's prior
written consent, WHICH CONSENT SHALL NOT BE UNREASONABLY WITHHELD OR DELAYED.
Any attempted transfer without consent shall be void and shall constitute a
breach of this Lease. No transfer permitted hereunder shall release Tenant or
change Tenant's primary liability to pay the Rent. Landlord's acceptance of Rent
from any other person is not a waiver of any provision of this Lease. Consent to
one transfer is not a consent to any subsequent transfer. If Tenant's transferee
defaults under this Lease, Landlord may proceed directly against Tenant without
pursuing remedies against the transferee. EXCEPT AS SET FORTH BELOW, IN THE
EVENT OF ANY SUBLET OR ASSIGNMENT, ANY PROFIT SHALL BE SPLIT EQUALLY BETWEEN
LANDLORD AND TENANT. TENANT SHALL HAVE THE RIGHT, WITHOUT LANDLORD'S CONSENT, TO
ENTER INTO AN ASSIGNMENT OR SUBLEASE WITH: (I) TENANT'S PARENT CORPORATION; (II)
ANY SUBSIDIARY CORPORATION OF TENANT OR TENANT'S PARENT CORPORATION; OR (III)
ANY AFFILIATED ENTITY IN WHICH TENANT, TENANT'S PARENT CORPORATION OR ANY
SUBSIDIARY OF EITHER HOLDS A MAJORITY OF THE OUTSTANDING SHARES OF OWNERSHIP
INTERESTS. NONE OF THESE EXEMPT TRANSFERS SHALL OBLIGATE TENANT TO SHARE WITH
LANDLORD ANY CONSIDERATION PAID IN CONNECTION THEREWITH. REGARDLESS OF ANY
TRANSFER, TENANT SHALL IN ALL INSTANCES REMAIN LIABLE UNDER THE LEASE.

              15.  TENANT'S INSURANCE. Tenant agrees to provide comprehensive
public liability insurance with an insurance company REASONABLY satisfactory to
Landlord, naming Landlord as an additional insured, in amounts not less than
$500,000 per person and $1,000,000 per accident, and $500,000 for damage to
property. Tenant shall deliver to Landlord a copy of such policy of insurance
prior to the Commencement Date and a copy of any renewal policy at least ten
(10) days prior to the expiration date of any existing policy. Such policies
shall specifically provide that they shall not be cancelable or subject to
reduction of coverage except after thirty (30) days' prior written notice to
Lessor.

<PAGE>   17

              16.  INDEMNIFICATION. Landlord shall indemnify Tenant against and
hold Tenant harmless from any and all cost, claims or liability arising from any
breach or default in the performance of Landlord obligations under the Lease OR
ANY MATERIAL MISREPRESENTATION OR MATERIAL BREACH OF WARRANTY BY LANDLORD UNDER
THIS LEASE; Tenant shall indemnify Landlord against and hold Landlord harmless
from any and all costs, claims or liability arising from: (a) Tenant's use of
the Premises; (b) the conduct of Tenant's business or anything else done or
permitted by Tenant to be done in or about the Premises; (c) any breach or
default in the performance of Tenant's obligations under this Lease; or (d) any
misrepresentation or breach of warranty by Tenant under this Lease. Tenant shall
defend Landlord against any such costs, claims or liabilities at Tenant's
expense with counsel reasonably acceptable to Landlord or, at Landlord's
election, Tenant shall reimburse Landlord for any legal fees or costs incurred
by Landlord in connection with any such claim. As a material part of the
consideration to Landlord, EXCEPT AS PROVIDED FOR IN THIS PARAGRAPH 16 Tenant
hereby assumes all risk of damage to property or injury to persons in or about
the Premises arising from any cause, and Tenant hereby waives all claims in
respect thereof against Landlord, except for any claim arising out of Landlord's
gross negligence or willful misconduct.

              17.  WAIVER OF SUBROGATION. Landlord and Tenant agree, provided
that such agreement does not invalidate or prejudice any policy of insurance,
that, in the event the Premises or the fixtures, leasehold improvements,
furniture, equipment's, or merchandise therein, are damaged or destroyed by fire
or other casualty which is covered by insurance of either the Landlord or the
Tenant, the rights of either party, if any, against the other, or against the
employees, agents, or licensees of any party with respect to such damage or
destruction and with respect to any loss resulting therefrom, including the
interruption of the business of any party, are hereby waived to the extent of
the coverage of said insurance. Landlord and Tenant agree further that all
policies of fire, extended coverage, business interruption, all risk or other
insurance covering the Premises, or the contents, fixtures, equipment and
improvements thereon, shall, if obtainable, contain a clause or endorsement
providing in substance that the insurance shall not be prejudiced by virtue of
this waiver. Any additional premiums on account thereof shall be paid by the
party benefited.

                    17.1 LIENS. Tenant shall not permit any lien or claims for
lien including without limitation, any mechanic, laborer or supplier lien to be
filed against the Building or any part thereof arising out of work performed or
alleged to have been performed by, at the direction of or on behalf of Tenant.
If any such lien or claim for lien is filed, Tenant shall within thirty (30)
days after such filing either have such lien or claim for lien released of
record or MAY CONTEST SUCH LIEN AND IN SUCH CASES shall deliver to Landlord a
bond or other security in form, content, amount, and issued by a company
satisfactory to Landlord, indemnifying Landlord, and others designated by
Landlord against all costs and liabilities resulting from such lien or claim for
lien released or to deliver such bond to Landlord. If Tenant fails to delete
contest any lien, Landlord, without investigating the validity of such lien, may
pay or discharge the same and Tenant shall reimburse Landlord upon demand for
the amount so paid by Landlord including Landlord's expense and attorney's fees.

              18.   DAMAGE OR DESTRUCTION.

                    18.1 Partial Damage to Premises. Tenant shall notify
Landlord in writing immediately upon the occurrence of any damage to the
Premises. If the damage can be completely repaired within ninety (90) days from
the date of such damage and the cost of such repairs do not exceed fifty percent
of the value of the Premises, Landlord shall repair the damage as soon as
reasonably possible. If the damage cannot be repaired within 90 days of the date
of such damages or the cost of such repairs exceeds 50% of the value of the
premises this Lease SHALL TERMINATE as of the date the damage occurred. Landlord
shall notify Tenant within thirty (30) days after receipt of notice of the
occurrence of the damage, whether Landlord elects to repair the damage or
terminate the Lease. If the damage to the Premises occurs during the last six
(6) months of the Lease Term, and if such damage or destruction is not the
result of the act or omission of Tenant, Landlord or Tenant may elect to
terminate this Lease.

                    18.2 TOTAL OR SUBSTANTIAL DESTRUCTION. If the Premises is
totally or substantially destroyed by any cause whatsoever, or if the Premises
is in a building which is substantially destroyed (even though the Premises is
not totally or substantially destroyed), this Lease shall terminate as of the
date the destruction occurred. However, if the Premises can be rebuilt within
one hundred and twenty (120) days after the date of destruction, Landlord may
elect to rebuild the Premises at Landlord's own expense, in which case, this
Lease shall remain in full force and effect. Landlord shall notify Tenant of
such election within thirty (30) days after the occurrence of total or
substantial destruction.

                    18.3 TEMPORARY REDUCTION OF RENT. If the Premises is totally
or substantially destroyed, or if the Premises is damaged through no fault of
Tenant, and the Premises is repaired pursuant to the provisions of this
PARAGRAPH 18, Rent payable during the period of such damage, repair and/or
restoration shall be reduced according to the degree, if any, to which Tenant's
use of the Premises is impaired. Tenant shall not be entitled to any other
compensation, reduction, or reimbursement from Landlord as a result of any
damage, destruction, repair, or restoration of or to the Premises.

              19.   Condemnation. If all or any portion of the Premises is taken
through eminent domain or sold under threat of such taking (all of which are
called "Condemnation"), this Lease shall terminate as to the part taken or sold
on the date the condemning authority takes title or possession, whichever occurs
first. Any Condemnation award or payment shall be distributed in the following
order: (a) first, to any ground lessor, mortgagee or beneficiary under a deed of
trust encumbering the Premises for the amount of its interest in the Premises;
(b) second, to Landlord for reduction in the value of the leasehold, the taking
of the fee, or otherwise; (c) third, to tenant for
<PAGE>   19
reimbursement of unamortized tenant improvements, trade fixtures and moving
expense caused by such condemnation.

         20.  DEFAULT AND REMEDIES AND BANKRUPTCY.

              A. If Tenant shall default in the payment of any installment of
Rent or in the payment of any other sum required to be paid by Tenant under this
Lease and such default shall continue for ten (10) days after payment thereof is
due, or if Tenant shall default in the observance or performance of any of the
other covenants or conditions in this Lease to be performed by Tenant and such
default shall continue for thirty (30) days after written notice to Tenant
(provided, however, that if Tenant shall default with respect to such payments
or observances or performances more than twice in any six (6) month period
within the Term, then no notice of any further default with respect to such
matters within such period shall be required hereunder), or if a default
involves a hazardous condition or an event which in Landlord's judgment is
materially detrimental to the Building and within the control of Tenant, and is
not cured by Tenant immediately upon written notice to Tenant, or if the
interest of Tenant in this Lease shall be levied upon under execution or other
legal process, or if any voluntary petition in bankruptcy or for corporate
reorganization or any similar relief shall be filed by Tenant, or if any
involuntary petition in bankruptcy shall be filed against Tenant under any
federal or state bankruptcy or insolvency act and shall not have been dismissed
within sixty (60) days following the filing thereof, or if a receiver shall be
appointed for Tenant or any of the property of Tenant by any court and such
receiver shall not be dismissed within sixty (60) days from the date of
appointment, or if Tenant shall make an assignment for the benefit of creditors,
or if Tenant shall admit in writing its inability to meet its debts as they
mature, or if Tenant shall abandon the Premises, then Landlord may treat the
occurrence of any one or more of the foregoing events as a breach of this Lease
and thereupon at its option may, without notice or demand of any kind to Tenant
or any other person, exercise one or more of the following described remedies,
in addition to all other rights and remedies provided at law or in equity:

              (i) Landlord may terminate this Lease, in which event Landlord may
    immediately repossess the Premises and be entitled to recover, in addition
    to any other sums or damages for which Tenant may be liable to Landlord, as
    damages, an amount, if any, equal to the Rent which would have been payable
    during any period of rent-free occupancy provided to Tenant by this Lease,
    the cost of all leasing commissions paid by Landlord in connection with this
    Lease, the cost of all leasing commissions paid by Landlord in connection
    with this Lease, the cost to Landlord of the initial leasehold improvements
    to the Premises, and all other amounts paid to or on behalf of Tenant in
    connection with Tenant's entry into this Lease and occupancy of the Premises
    (including without limitation any moving cost allowance, payments on
    lease(s) assumed by Landlord, payment for preparation of floor plans and the
    like), including Landlord's interest expense thereon, together with a sum of
    money equal to the excess of the Rent provided to be paid by Tenant for the
    balance of the Term over the fair market rental value of the Premises, after
    deduction of all anticipated expenses of reletting for said period. Should
    the fair market rental value of the Premises after deduction of all
    anticipated expenses of reletting for the balance of the

<PAGE>   20

then existing Term exceed the Rent to be paid by Tenant for the balance of the
Term, Landlord shall have no obligation to pay to Tenant the excess or any part
thereof or to credit such excess or any part thereof against any other sums or
damages for which Tenant may be liable to Landlord.

   (ii) Landlord may terminate Tenant's right of possession and may repossess
the Premises by forcible entry or unlawful detainer suit by taking peaceful
possession or otherwise without terminating this Lease, in which event Landlord
may, but shall be under no obligation to, relet the same for the account of
Tenant; for such rent and upon such terms as shall be satisfactory to Landlord.
For the purpose of such reletting, Landlord is authorized to decorate, repair,
remodel or alter the Premises. If Landlord shall fail to relet the Premises,
Tenant shall pay to Landlord a sum equal to the amount of the Rent for the
balance of the Term. If the Premises are relet and a sufficient sum shall not be
realized from such reletting after payment of the costs and expenses of all
decoration, repairs, remodeling, alterations and additions and the expenses of
such reletting (including broker's fees) to satisfy the Rent provided for in
this Lease and the amounts recoverable by Landlord from Tenant pursuant to
subparagraph (i) of this paragraph, Tenant shall satisfy and pay the same upon
demand therefor from time to time. Landlord may file suit to recover any sums
falling due from time to time and no suit or recovery of any portion due
Landlord hereunder shall be any defense to any subsequent action brought for any
amount not previously reduced to judgment in favor of Landlord. No waiver of any
default by Tenant shall be implied from any omission by Landlord to take any
action on account of said default if such default persists or shall be repeated,
and no express waiver shall affect any default other than the default specified
in the express waiver and then only for the time and to the extent therein
stated. No failure of Landlord to exercise any power given Landlord hereunder or
to insist upon strict compliance with any obligation hereunder and no custom or
practice of the parties at variance with the terms hereof shall constitute a
waiver of Landlord's right to demand exact compliance with the terms hereof. The
provisions of this Paragraph 20 shall survive any termination of this Lease.

B. The following shall be events of bankruptcy ("Events of Bankruptcy") under
this Lease:

        [1] Tenant's becoming insolvent, as that term is defined under the
Bankruptcy Code, or under the insolvency laws of any state, district,
commonwealth or territory of the United States (the "Insolvency Laws");

        [2] The appointment of a receiver or custodian for any material part of
Tenant's property or assets, or the institution of a foreclosure action upon any
material part of Tenant's real or personal property;

        [3] The filing of a voluntary petition under the provisions of the
Bankruptcy Code or Insolvency Laws;

        [4] The filing of an involuntary petition against Tenant as the subject
debtor under the Bankruptcy Code or Insolvency Laws, which either [a] is not
dismissed within

<PAGE>   21

    sixty (60) thirty (30) days of filing, or [b] results in the issuance of an
    order for relief against the debtor; or

              [51 Tenant's making or consenting to an assignment for the benefit
    of creditors or a common law composition of creditors.

         C. Upon the occurrence of an Event of Bankruptcy, Landlord shall have
all rights and remedies available to Landlord pursuant to Subparagraph 20.A
hereof; provided that, while a case under the Bankruptcy Code is pending in
which Tenant is the subject debtor and only for so long as Tenant or its Trustee
in Bankruptcy hereinafter referred to as "Trustee") is in compliance with the
provisions of Subparagraphs D, E and F below, Landlord shall not exercise its
rights and remedies pursuant to Subparagraph 20.A hereof.

         D. If Tenant becomes the subject debtor in a case pending under the
Bankruptcy Code, Landlord's right to terminate this Lease pursuant to
Subparagraph 20.C above shall be subject to the rights of Trustee to assume or
assign this Lease. Trustee shall not have the right to assume or assign this
Lease unless Trustee promptly [i] cures all defaults under this Lease, [ii]
compensates Landlord for monetary damages incurred as a result of such defaults,
and [iii] provides "adequate assurance of future performance" on the part of the
Tenant as debtor in possession or on the part of the assignee tenant.

         E. Landlord and Tenant hereby agree in advance that "adequate assurance
of future performance," as used in Subparagraph D above, shall mean that all of
the following minimum criteria must be met:

              [1] Trustee must agree that Tenant's business shall be conducted
    in a appropriate manner, and that no liquidating sales, auctions, or other
    inappropriate business operations shall be conducted on the Premises;

              (2] Trustee must agree that the use of the Premises as stated in
    this Lease will remain unchanged and that no prohibited use shall be
    permitted;

              [3] Trustee must agree that the assumption or assignment of this
    Lease will not violate or affect the rights of any sublessees of space in
    the Premises;

              [4] Trustee must pay to Landlord at the time the next monthly
    installment of Rent is due under this Lease, in addition to such Monthly
    Basic Rent Installment of Rent, an amount equal to the Monthly Basic Rent
    Installments due under this Lease for the next three (3) months, said amount
    to be held by Landlord in escrow until either Trustee or Tenant defaults in
    its payment of Rent or other obligations under this Lease (whereupon
    Landlord shall have the right to draw on such escrowed funds to pay all or
    any portion of unpaid sums due under this Lease) or until the expiration of
    this Lease (whereupon the funds shall be returned to Trustee or Tenant); and



<PAGE>   22

            [5] Tenant or Trustee must agree to pay to Landlord promptly at
    any time Landlord is authorized to and does' draw on the escrow account the
    amount necessary to restore such escrow account to the original level
    required by Subparagraph [4] of this Subparagraph E.

         F. In the event Tenant is unable to [i] cure its defaults, [ii]
promptly reimburse the Landlord for its monetary damages, [iii] pay the Rent and
all other payments required of Tenant under this Lease on time (or within ten
(10) days of the due date, or [iv] meet the criteria and obligations imposed by
Subparagraph 20.E above, Tenant agrees in advance that it has not met its burden
to provide "adequate assurance of future performance," and this Lease may be
terminated by Landlord in accordance with Subparagraphs 20.A and 20.C above.

         G. Any property, furniture or fixtures belonging to Tenant which
Landlord may store shall be stored at Tenant's expense and at Tenant's sole risk
and Landlord shall not be held responsible for any breakage or damage occasioned
by such storing. If this Lease is terminated at the election of Landlord, as
aforesaid, or in any other way, Tenant shall, without demand, surrender and
deliver up said Premises and property peaceably to Landlord immediately upon
such termination, and if Tenant shall remain in possession of the Premises, or
any part thereof, one day after the termination of this Lease in any of the ways
above named, Tenant shall be deemed guilty of forcible detainer of the Premises
under the statutes of the State of Kentucky and shall be subject to all the
conditions and provisions above named and to eviction and removal forcibly or
otherwise with or without process of law as above stated. Any property,
furniture or fixtures belonging to Tenant which Landlord may store shall be
stored at Tenant's expense and at Tenant's sole risk and Landlord shall not be
held responsible for any breakage or damage occasioned by such storing after the
commencement of a suit, or after final judgment, for possession of said
Premises, Landlord may receive and collect any Rent due from Tenant, and the
payment of said Rent shall not waive or affect said suit or said judgment. All
rights of Landlord in the event of default herein enumerated shall be in
addition to and without prejudice to any remedy or remedies which Landlord may
have at law or in equity for nonpayment of rent or for breaches of the covenants
and agreements hereof.



<PAGE>   23


         H.  All rights, options and remedies of Landlord contained in this
Lease shall be construed and held to be cumulative, and not one of them shall be
exclusive of the other, and Landlord shall have the right to pursue any one or
all of such remedies or any other remedy or relief which may be provided by law,
whether or not stated in this Lease. No waiver of any default of Tenant
hereunder shall be implied from any acceptance by Landlord of any Rent or other
payments due hereunder or any omission by Landlord to take any action on account
of default if such default persists or is repeated, and no express waiver shall
affect defaults other than as specified in said waiver. The consent or approval
of Landlord to or of any act by Tenant requiring Landlord's consent or approval
shall not be deemed to waive or render unnecessary Landlord's consent or
approval to or of any subsequent similar acts by Tenant.

         I.  Landlord shall in no event be in default in the performance of any
of its obligations in this Lease Agreement unless and until Landlord shall have
failed to perform such obligation within thirty (30) days (or such additional
time as is reasonably required to correct any such default provided Landlord
continuously is acting in good faith to cure such default and such default is
capable of being cured) after notice by Tenant to Landlord in writing and
pursuant to the terms of this Lease concerning notice specifying wherein
Landlord has failed to perform any such obligation.

         21. INTEREST ON PAST DUE AMOUNTS. Any amount owed by Tenant to Landlord
which is not paid when due shall bear interest at the rate of  ten percent (10%)
per annum from the due date of such amount, in addition to any late charges due
under this Lease. If the interest rate specified in this Lease is higher than
the rate permitted by law, the interest rate is hereby decreased to the maximum
legal interest rate permitted by law.

         22. SECURITY DEPOSIT. Upon the execution of this Lease, Tenant shall
deposit with Landlord a Security Deposit in the amount of $ 0.00.

         23. DEFAULT BY LANDLORD. Tenant shall give written notice of any
failure by Landlord to perform any of its obligations under this Lease to
Landlord. Landlord shall not be in default under this Lease unless Landlord
fails to cure such non-performance within thirty (30) days after receipt of
Tenant's notice. However, if such non-performance reasonably requires more than
thirty (30) days to cure, Landlord shall not be in default if such cure is
commenced within such thirty (30) day period and thereafter diligently pursued
to completion.

         24. LEGAL PROCEEDINGS. Should this Lease or the parties' obligations
hereunder be the subject of litigation between Landlord and Tenant, it is
expressly agreed that the prevailing party will have its reasonable legal fees,
costs and expenses reimbursed by the other party.

         25. NOTICES. All notices required or permitted under this Lease shall
be in writing and shall be personally delivered or sent by certified or
registered mail, return receipt requested, or sent by Federal Express or other
recognized delivery service. Notices shall be




                                       20

effective upon delivery or attempted delivery in accordance with this Section.

Either party may change its notice address upon written notice to the other
party.

         26.  QUIET POSSESSION. Upon paying the Rent and observing and
performing all of the covenants, conditions and provisions on Tenant's part to
be observed and performed hereunder, Tenant shall have quiet possession of the
Premises for the entire Term, subject to all of the provisions of this Lease.

         27.  SUBORDINATION AND ATTORNMENT.

              27.1 SUBORDINATION. Landlord shall have the right to subordinate
this Lease to any ground lease, deed of trust or mortgage encumbering the
Premises, any advances made on the security thereof and any renewals,
modifications, consolidations, replacements or extensions thereof, whenever made
or recorded. However, Tenant's right to quiet possession of the Premises during
the Term shall not be disturbed if Tenant pays the Rent and performs all of
Tenant's obligations under this Lease and is not otherwise in default. If any
ground lessor, beneficiary or mortgagee elects to have this Lease prior to the
lien of its ground lease, deed of



                                       21

<PAGE>   25

trust or mortgage and gives written notice thereof to Tenant, this Lease shall
be deemed prior to such ground lease, deed of trust or mortgage whether this
Lease is dated prior or subsequent to the date of said ground lease, deed of
trust or mortgage or date of recording thereof.

              27.2 ATTORNMENT. If Landlord's interest in the Premises is
acquired by any ground lessor, beneficiary under a deed of trust, mortgagee, or
purchaser at a foreclosure sale, Tenant shall attorn to the transferee of or
successor to Landlord's interest in the Premises and recognize such transferee
or successor as Landlord under this Lease provided such party obtaining
Landlord's interest in the Premises recognizes Tenant's interest under this
Lease and agrees not to disturb the same. Tenant waives the protection of any
statute or rule of law which gives or purports to give Tenant any right to
terminate this Lease or surrender possession of the Premises upon the transfer
of Landlord's interest.

              27.3 SIGNING OF DOCUMENTS. Provided the provisions of
Subparagraphs 27.1 and/or 27.2 are met, Tenant shall sign and deliver any
instrument or documents necessary or appropriate to evidence any such attornment
or subordination or agreement to do so. Such subordination and attornment
documents may contain such provisions as are customarily required by any ground
lessor, beneficiary under a deed of trust or mortgagee. If Tenant fails to do so
within ten (10) days after written request, Tenant hereby makes, constitutes and
irrevocably appoints Landlord, or any transferee or successor of Landlord, the
attorney-in-fact of Tenant to execute and deliver any such instrument or
document.

              27.4 MORTGAGEE PROTECTION. Tenant agrees to give any mortgagees
and/or trust deed holders, by registered mail, a copy of any notice of default
served upon Landlord, provided that prior to such notice Tenant has been
notified, in writing (by way of Notice of Assignment of Rents and Leases, or
otherwise), of the address of such mortgagees and/or trust deed holders. Tenant

the term provided for in this Lease, then the mortgagees and/or trust deed
holders shall have an additional thirty (30) days within which to cure such
default or, if such default cannot be cured within that time, then such
additional time as may be necessary, if within such thirty (30) days any

remedies necessary to cure such default (including, but not limited to,
commencement of foreclosure proceedings, if necessary to effect such cure), in
which event this Lease shall not be terminated while such remedies are being so
diligently pursued.

         29. LANDLORD'S LIABILITY. The obligations of the Landlord under this
Lease do not constitute personal obligations of Landlord or the individual
partners, joint ventures, directors, officers, shareholders or beneficial owners
of the Landlord, and Tenant shall look solely to the Building and to no other
assets of the Landlord for satisfaction of any liability in respect to this
Lease. Tenant will not seek recourse against Landlord or such individuals or
entities or such other assets for such satisfaction. As used in this Lease, the
term "Landlord" means only the current owner or owners of the fee title to the
Premises or the leasehold estate under a ground lease of the Premises at the
time in question. Any Landlord who transfers its title or interest is relieved
of all liability with respect to the obligations of Landlord under this Lease to
be performed on or after the date of transfer. However, each Landlord shall
deliver to its transferee, by actual transfer or appropriate credits, all funds
previously paid by Tenant if such funds have not yet been applied under the
terms of this Lease.

Landlord warrant and represents to the other that no other broker was involved
with the leasing of the Premises or the negotiation of this Lease or is entitled
to any commission in connection herewith. Landlord shall be solely responsible
for any commission or fee or other compensation payable to Broker arising from
this Lease. Tenant and Landlord agrees to indemnify and hold the other harmless
against any other claims (including court costs and attorneys fees) for
commissions by any other broker.

         31. SURRENDER OF PREMISES. Upon termination of the Lease, by expiration
of term, or otherwise, Tenant shall redeliver to Landlord the Premises broom
clean and in good order and condition, ordinary wear and tear excepted. In
addition, Landlord may require Tenant to remove any alterations, additions or
improvements (whether or not made with Landlord's consent) prior to the
termination of the Lease and to restore the Premises to its prior condition, all
at Tenant's expense. If Landlord shall require such removal, Landlord shall
provide notice to Tenant no later than ninety (90) days prior to the end of the
Lease term. All alterations, additions and improvements which Landlord has not
required Tenant to remove and which Tenant has not removed shall become
Landlord's property and shall be surrendered to Landlord upon the termination of
the Lease. Tenant shall remain liable for holdover rent until the Premises shall
be returned in such order to Landlord.

         32. HOLDOVER. Tenant shall vacate the Premises upon the expiration or
earlier termination of this Lease. Tenant shall reimburse Landlord for and
indemnify Landlord against all damages incurred by Landlord from any delay by
Tenant in vacating the Premises. If Tenant




                                       23
<PAGE>   27


does not vacate the Premises upon the expiration or earlier termination of the
Lease and Landlord thereafter accepts rent from Tenant, Tenant's occupancy of
the Premises shall be a "month-to-month tenancy, subject to all of the terms of
this Lease applicable to a month-to-month tenancy, except that the Base Rent for
such tenancy shall be two hundred percent (200%) of the Base Rent in effect at
the expiration of the Lease.

         33. SEVERABILITY. A determination by a court of competent jurisdiction

shall not cancel or invalidate the remainder of such provision or this Lease,
which shall remain in full force and effect.

         34. INTERPRETATION. The captions of the Sections of this Lease are to
assist the parties in reading this Lease and are not a part of the terms or
provisions of this Lease. Whenever required by the contest of this Lease, the

masculine, feminine and neuter genders shall each include the other. In any
provision relating to the conduct, acts or omissions of Tenant, the term
"Tenant" shall include Tenant's agents, employees, contractors, invitees,
successors or others using the Premises with Tenant's expressed or implied
permission.

         35. INCORPORATION OF PRIOR AGREEMENTS; MODIFICATIONS. This Lease is the
only agreement between the parties pertaining to the lease of the Premises and
no other agreements are effective. All amendments to this Lease shall be in
writing and signed by all parties. Any other attempted amendment shall be void.

         36. WAIVERS. All waivers must be in writing and signed by the waiving
party. Landlord's failure to enforce any provision of this Lease or its
acceptance of Rent shall not be a waiver and shall not prevent Landlord from
enforcing that provision or any other provision of this Lease in the future. No
statement on a payment check from Tenant or in a letter accompanying a payment
check shall be binding on Landlord. Landlord may, with or without notice to
Tenant, negotiate such check without being bound to the conditions of such
statement.

         37. NO RECORDATION. Tenant shall not record this Lease without prior
written consent from Landlord. However, either Landlord or Tenant may require
that a "Short Form" memorandum of this Lease executed by both parties be
recorded.

         38. BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon any
party who legally acquires any rights or interest in this Lease from Tenant.
However, Landlord shall have no obligation to Tenant's successor unless the
rights or interests of Tenant's successor are acquired in accordance with the
terms of this Lease. The laws of the State of Kentucky shall govern the
validity, performance and enforcement of this Lease.

         39. CORPORATE AUTHORITY; PARTNERSHIP AUTHORITY. If Tenant is a
corporation, each person signing this Lease on behalf of Tenant represents and
warrants that he has full authority to do so and that this Lease binds the
corporation. If Tenant is a partnership, each person signing this Lease for
Tenant represents and warrants that he is a general partner of





                                       24

<PAGE>   28



the partnership, that he has full authority to sign for the partnership and that
this Lease binds the partnership and all general partners of the partnership.
The withdrawal of a General Partner from the Partnership shall not relieve the
General Partner from liability under this Lease and all general partners added
to the Partnership shall be fully liable for the Partnership's obligations
hereunder. Tenant shall give written notice to Landlord of any general partner's
withdrawal or addition.

         40. JOINT AND SEVERAL LIABILITY. All parties signing this Lease as
Tenant shall be jointly and severally liable for all obligations of Tenant.

         41. FORCE MAJEURE. If EITHER PARTY cannot perform any of its
obligations HEREUNDER (EXCEPT TENANT OBLIGATION TO PAY RENT) due to events
beyond their control, the time provided for performing such obligations shall be
extended by a period of time equal to the duration of such events. Events beyond
a PARTY'S control include, but are not limited to, acts of God, war, civil
commotion, labor disputes, strikes, fire, flood or other casualty, shortages of
labor or material, government regulation or restriction and weather conditions.

         42. EXECUTION OF LEASE. This Lease may be executed in counterparts,
and, when all counterpart documents are executed, the counterparts shall
constitute a single binding instrument.

         43. COVENANTS AND CONDITIONS. Tenant's performance of each of Tenant's
obligations under this Lease is a condition as well as a covenant. Tenant's
right to continue in possession of the Premises is conditioned upon such
performance. Time is of the essence in the performance of all covenants and
conditions.

         44. SUBMISSION OF LEASE. The submission of this Lease to Tenant for
examination does not constitute an offer to lease or a reservation of space. No
agreement between Landlord and Tenant relating to the leasing of the Premises
shall become effective or binding until executed by both parties and received by
Tenant.

         45.

         46. RIGHT OF FIRST REFUSAL. During the initial five (5) year term of
this Lease, and provided that Tenant is not then in default under the terms,
covenants, and of this Lease, Tenant shall have the right of first refusal TO
LEASE any adjoining space occupied by Tenant. Landlord shall notify Tenant in
writing that it is under firm negotiations with a prospective tenant to lease
the demised Premises, or any part thereof, and should Tenant decide to lease
said space, Tenant may do so under the same terms and conditions as prospective
tenant. Tenant must notify Landlord in


                                       25

Lease for two (2) additional five (5) year periods from the date of expiration
of this Lease, which notice of exercise of this option shall be given separately

paid by the Tenant shall be $4.50 per square foot during the first renewal term
and $4.75 per square foot during the second renewal term.

         IN WITNESS WHEREOF, the parties have hereunder executed the lease the

         2.   Term

              (a) The term of this Lease shall commence on the 1st day of
January, 1997, and shall end December 31, 2006.

              (b) Tenant shall have the option to extend the term of this Lease
for not less than the entire premises leased at the end of the initial term on

extended term is to commence, such extended term shall not commence and this
Lease shall expire at the end of the initial term or the initial extended term
then in effect. The Base Rent payable during the extended term(s) hereof shall
be subject to Landlord's and Tenant's agreement and in no event less than the
then prevailing rental paid by Tenant at the expiration of the initial term of
this Lease or the initial extended term, as the case may be, adjusted as of the
commencement of the extended term for which the option is exercised, both
otherwise such extended term(s) shall be upon the same terms and conditions as
set forth herein.

              Upon adjustment of the Base Rent and any other provisions of this
lease in accordance with this Paragraph 2, the parties shall immediately execute
an amendment to this Lease stating such adjustment.

         3.   Rental

              (a) Commencing on the Rental commencement Date as defined in
Paragraph 2(a) above, Tenant shall pay to Landlord, throughout the term of this
Lease, the following amounts as base rental for the premises (the "Base Rent")
subject to adjustment as provided in this Paragraph 3, on or before the l0th day
of the first full calendar month of the term hereof and on or before the tenth
day of each and every successive calendar month thereafter during the term
hereof.

              The monthly Base Rent for the premises is Eight Thousand Three
Hundred Thirty-three Dollars ($8,333.00).

              (b) The monthly Base Rent set forth in Paragraph 3(a) above shall
be subject to adjustment annually on each anniversary of the Rental Commencement
Date (the "Adjustment Date") as follows:

              The base for computing the adjustment shall be the final Consumer
Price Index for all Urban Consumers in the United States published by the United
States Department of Labor, Bureau of Labor Statistics (the "Index"), which is
published for the month most recently preceding the Rental Commencement Date
("Beginning Index"). If the Index published most recently preceding an
Adjustment Date ("Adjustment Index") has increased or decreased with respect to
the Beginning Index, the monthly Base Rent for the period until the next annual
Adjustment Date shall be set by multiplying the monthly Base Rental by a
fraction, the numerator of which is the Adjustment Index and the denominator of
which is the Beginning Index. In no case shall the monthly Base Rent be less
than the full monthly Base Rent set forth in Paragraph 3(a). On adjustment of
the monthly Base Rent as provided in this Lease, the parties shall immediately
execute an amendment to the Lease stating the new monthly Base Rent.

<PAGE>   3

              If the Index is changed so that the base year differs from that
used as of the month most recently preceding the month in which the term
commences, the Index shall be converted in accordance with the conversion factor
published by the United States Department of Labor, Bureau of Labor Statistics.
If the Index is discontinued or revised during the term, such other government
index or computation with which it is replaced shall be used in order to obtain
substantially the same result as would be obtained if the Index has not be
discontinued or revised.

         4.   Absolutely Net Lease

              The parties understand and agree that this Lease is deemed an
absolutely net lease wherein Tenant shall pay and be responsible for all

such tax upon Landlord as would have been payable to Landlord before the
imposition of any such tax. All taxes and assessments payable for a period
partly within and

         6.   Use of Premises

provided in the hereinafter entitled paragraph "Destruction of Premises",
Tenant, at all times during the term hereof and at its condition and repair

hereof, at its own expense, public liability insurance in minimum amounts of
$                     for injury or death of one person, $
for injury or death arising out of any one occurrence, and $
for damage to property, such coverage to protect the Tenant and Landlord and any
such other persons, firms or corporations as are designated by Landlord.

              Tenant shall also obtain and maintain in full force during the
term hereof at its own expense, fire, extended coverage and special form
insurance on the improvements on the leased premises in an amount equal to not
less than one hundred percent (100%) of the actual replacement cost (exclusive
of foundation and excavation costs) of such improvements, which insurance shall
name Landlord and Tenant as co-insureds and shall contain a loss-payable
endorsement in favor of the beneficiary of any mortgage covering the subject
real property and provide that such policies cannot be cancelled without thirty
(30) days prior notice to such parties.

              Tenant, at its expense, shall maintain for the benefit of Landlord
so-called rental value insurance, protecting the Landlord from loss of rent or
income occasioned by damages to the premises as covered by such policies of
insurance, such loss of income to be guaranteed for a period of six (6) months
from the date of occurrence of the damage, in the full amount of all rentals due
and payable under Paragraph 3 above.

              All policies of insurance which Tenant is required to carry
hereunder shall be issued by good and responsible companies authorized to write
such insurance in South Dakota and shall provide that no cancellation or
material change in the coverage shall be made except after thirty (30) days
prior notice to Landlord. Tenant may, at its option, satisfy its obligations
under this paragraph by bringing said risks within the coverage of any so-called
blanket policy or policies of insurance which it may now or hereafter carry by
an appropriate amendment, rider, endorsement or otherwise so long as Landlord is
provided a certificate establishing that the coverage allocated to the premises
is in compliance with the terms of this Lease. Copies of all insurance policies
required under the provisions of this Lease shall be delivered to Landlord
punctually.

         10.  Indemnification

              Tenant hereby waives all claims against Landlord for damage to any
property or injury to or death of any person in, upon or about the premises
arising at any time and from any cause except to the extent that such is caused
by the sole and exclusive negligence or willful misconduct of Landlord. Tenant
shall hold Landlord harmless from any damage to any property or injury to or
death of any person arising from the use of the premises by Tenant, except to
the extent that such is caused by the sole and exclusive negligence or willful
misconduct of Landlord and, to such extent, Landlord agrees to hold Tenant
harmless from any such damage, injury or death. The foregoing indemnity
obligations shall include actual attorneys' fees paid or incurred in good faith,
investigation costs and all other reasonable costs and expenses incurred by the
party indemnified from the first notice that any claim or demand is to be made
or may be made. The provisions of this Paragraph 10 shall survive the
termination of this Lease with respect to any damage, injury or death occurring
before such termination.

         11.  Damage and Destruction of Premises

              In the event of a total or partial destruction of the improvements
constructed on the leased premises during the term of the Lease, from any cause
covered by the insurance described in Paragraph 9 of the Lease, Tenant shall
promptly repair the same, but such destruction shall not annul or void the
Lease; provided that the holder of any encumbrance makes the insurance proceeds
available to Tenant or in lieu thereof, the lender may hold said proceeds in
trust to be distributed to Tenant, or Tenant's subcontractors as the work
progresses and Tenant delivers certification of the same. The proceeds received
from the rental value insurance described in said Paragraph 9 shall be paid to
Landlord during the six (6) month period covered by said insurance but,
subsequent to said date, the rent reserved to be

paid hereunder shall be equitably adjusted according to the amount and value of
the undamaged space. Notwithstanding the provisions of this Paragraph 11, in the
event there is total destruction, or partial destruction to the extent of fifty
percent cent (50%) or more of the improvements constructed on the leased
premises during the last one hundred twenty (120) days of the initial term, or
during the last one hundred twenty (120) days of the extended term under any
option to extend this Lease, Tenant can elect to terminate this Lease by written
notice delivered to Landlord not more than thirty (30) days after the
destruction or damage, provided that in the event Tenant elects to so terminate,
the insurance proceeds payable under the insurance described in Paragraph 9
shall be the property of the Landlord.

              In the event of damage or destruction by any casualty other than a
casualty insured under the insurance referred to hereinabove, Landlord may
restore the premises or, at Landlord's option, may elect to terminate the Lease
and thereupon be released from further obligation under the Lease by giving
written notice thereof to Tenant within twenty (20) days after the occurrence of
such casualty, unless Tenant elects to restore the premises, by written notice
of such election to Landlord, delivered to Landlord within twenty (20) days
after the receipt of Landlord's written election to terminate the Lease, in
which event Tenant shall, as soon as reasonably possible, commence and proceed
diligently to restore the premises substantially to the condition thereof
immediately prior to such damage or destruction. If neither party elects to
restore the improvements, the Lease shall be terminated and thereupon the
Landlord and Tenant shall be released from further obligation thereunder, except
that Landlord shall be obligated to repay Tenant any unused prepaid rent paid to
Landlord.

         12.  Alterations

              Tenant shall not make, or suffer to be made, any alterations,
additions or improvements to or of the premises or any part thereof, without the
prior written consent of the Landlord. Any alterations, additions or
improvements to the premises shall be for Tenant's account on the basis of plans
and specifications approved by Landlord and shall become at once a part of the
realty and shall belong to the Landlord without compensation. If written consent
of the Landlord to any such proposed repairs or alterations by Tenant shall have
been obtained, Tenant agrees to advise Landlord in writing of the date upon
which such repairs or alterations will commence in order to permit Landlord to
post a notice of non-responsibility. Tenant agrees to save and hold Landlord
free and harmless against any liability, loss or damage (and to defend Landlord
by attorneys of Tenant's selection, at Tenant's sole expense) on account of any

mechanic's lien claim for work performed or materials furnished in
connection with such alterations.

         13.  Assignment and Subletting

              Tenant shall not either voluntarily, or by operation of law,
assign, transfer, mortgage, pledge, hypothecate or encumber this Lease or any
interest therein or in the shares of Tenant, and shall not sublet the premises
or any part thereof, or any right or privilege appurtenant thereto, or allow any
other person (the employees, agents, servants and invitees of Tenant excepted)
to occupy or use the premises, or any portion thereof, without first obtaining
the written consent of Landlord, which consent shall not be unreasonably
withheld. A consent to one assignment, subletting, occupation or use shall not
be deemed to be a consent to any subsequent assignment, subletting, occupation
or use. Consent to any such assignment or subletting shall in no way relieve
Tenant of any liability under this Lease. Any such assignment or subletting
without such consent, whether direct or indirect, shall be void and shall, at
the option of the Landlord, constitute a default under the terms of this Lease.

              In the event that Landlord shall consent to a sublease or
assignment hereunder, Tenant shall pay Landlord all reasonable fees, not to
exceed Five Thousand Dollars ($5,000.00), incurred in connection with the
processing of documents necessary to the giving of such consent.

         14.  Quiet Enjoyment

              The Tenant, upon paying the rent herein provided and performing
all and singular the covenants and conditions of the Lease on its part to be
performed, shall and may peaceably and quietly have, hold and enjoy legal
possession to the demised premises during the term hereof.

         15.  Events of Default

              The occurrence of any one or more of the following events ("Events
of Default") shall constitute a breach of this Lease by Tenant: (a) if Tenant
shall fail to pay any rental when and as the same becomes due and payable and
such failure shall continue for more than three (3) days after Tenant receives
notice of nonpayment from Landlord; or (b) if Tenant shall fail to pay any other
sum when and as the same becomes due and payable and such failure shall continue
for more than ten (10) days after Tenant receives notice of nonpayment from
Landlord; or (c) if Tenant shall fail to perform or observe any other term
hereof to be performed or observed by Tenant, such failure shall continue for
more than thirty (30) days after Tenant receives notice thereof from Landlord,
and Tenant shall not, within such period, commence with due diligence and
dispatch the curing of such default or,

having so commenced, shall thereafter fail or neglect to prosecute or complete
with due diligence and dispatch the curing of such default; or (d) if Tenant
shall make a general assignment for the benefit of creditors, or shall admit in
writing its inability to pay its debts as they become due, or shall file a
petition in bankruptcy, or shall be adjudicated as bankrupt or insolvent, or
shall file a petition in any proceeding seeking any reorganization, arrangement,
composition, readjustment, liquidation, dissolution or similar relief under any
present or future statute, law or regulation, or shall file an answer admitting
or fail timely to contest the material allegations of a petition filed against
it in any such proceeding, or shall seek or consent to or acquiesce in the
appointment of any trustee, receiver or liquidator of Tenant or any material
part of its properties; or (e) if within sixty (60) days after the commencement
of any proceeding against Tenant seeking any reorganization, arrangement,
composition, readjustment, liquidation, dissolution or similar relief under any
present or future statute, law or regulation, such proceeding shall not have
been dismissed, or if, within sixty (60) days after the appointment without the
consent or acquiescence of Tenant, of any trustee, receiver or liquidator of
Tenant or of any material part of its properties, such appointment shall not
have been vacated; or (f) if this Lease or any estate of Tenant hereunder shall
be levied upon under any attachment or execution and such attachment or
execution is not vacated within ten (10) days.

         16.  Termination Upon Default

              If an Event of Default shall occur, Landlord at any time
thereafter may give a written termination notice to Tenant, and on the date
specified in such notice (which shall be not less than three (3) days after the
giving of such notice) Tenant's right to possession shall terminate and this
Lease shall terminate, unless on or before such date all arrears of rental and
all other sums payable by Tenant under this Lease (together with interest
thereon at the then maximum legal rate) and all costs and expenses incurred by
or on behalf of Landlord hereunder shall have been paid by Tenant and all other
breaches of this Lease by Tenant at the time existing shall have been fully
remedied to the satisfaction of Landlord. Upon such termination, Landlord may
accumulatively recover from Tenant: (a) the worth at the time of award of the
unpaid rental which had been earned at the time of termination; and (b) the
worth at the time of award of the amount by which the unpaid rental which would
have been earned after termination until the time of award exceeds the amount of
such rental loss that Tenant proves could have been reasonably avoided; and (c)
the worth at the time of award of the amount by which the unpaid rental for the
balance of the term of this Lease after the time of award exceeds the amount of
such rental loss that Tenant proves could be reasonably avoided; and (d) any
other amount necessary to compensate Landlord for all the

detriment proximately caused by Tenant's failure to perform its obligations
under this Lease or which, in the ordinary course of events, would be likely to
result therefrom. The "worth at the time of award" of the amounts referred to in
clauses (a) and (b) above shall be computed by allowing interest at the then
maximum legal rate. The worth at the time of award of the amount referred to in
clause (c) above shall be computed by discounting such amount at the discount
rate of the Federal Reserve Bank of Minneapolis, Minnesota at the time of award
plus one percent (1%). For the purpose of determining unpaid rental under
clauses (a), (b) and (c) above, the monthly rent reserved in this Lease shall be
deemed to be the sum of the amounts last payable by Tenant pursuant to Paragraph
3 above.

    17.  Continuation After Default

         Even though Tenant has breached this Lease and abandoned the premises,
this Lease shall continue in effect for so long as Landlord does not expressly
terminate, in writing, Tenant's right to possession, and Landlord may enforce
all its rights and remedies under this Lease; including the right to recover the
rental as it becomes due under this Lease. Acts of maintenance, preservation,
efforts to relet the premises or the appointment of a receiver upon the
initiative of Landlord to protect Landlord's interest under this Lease shall not
constitute a termination of Landlord's right to possession.

    18.  Other Relief

         The remedies provided for in this Lease are in addition to any other
remedies available to Landlord at law or in equity by statute or otherwise.

    19.  Landlord's Right to Cure Defaults

         All agreements and provisions to be performed by Tenant under any of
the terms of this Lease shall be at its sole cost and expense and without any
abatement of rental. If Tenant shall fail to pay any sum of money and such
failure is unexcused under the terms hereof, other than rental required to be
paid by it hereunder, or shall fail to perform any other act on its part to be
performed hereunder and such failure shall continue for thirty (30) days after
notice thereof by Landlord, Landlord may, but shall not be obligated so to do
and without waiving or releasing Tenant from any obligations of Tenant, make any
such payment or perform any such other act on Tenant's part to be made or
performed as in this Lease provided. All sums so paid by Landlord and all
necessary incidental costs shall be deemed additional rent hereunder and shall
be payable to Landlord on demand, and Landlord shall have (in addition to any
other right or remedy of Landlord) the same rights and remedies in the event

                                       10                     DUPLICATE ORIGINAL

of the nonpayment thereof by Tenant as in the case of default by Tenant in the
payment of rental.

    20.  Attorney's Fees

         In the event of any action or proceeding brought by either party
against the other under this Lease, the prevailing party in any final judgment
or the nondismissing party in the event of a dismissal without prejudice shall
be entitled to the full amount of all reasonable expenses including all costs
and actual attorney's fees paid or incurred in good faith in connection
therewith.

    21.  Eminent Domain

         If all or any part of the premises shall be taken as a result of the
exercise of the power of eminent domain, this Lease shall terminate as to the
part so taken as of the date of taking and in the case of a partial taking,
either Landlord or Tenant shall have the right to terminate this Lease as to the
balance of the premises by written notice to the other within thirty (30) days
after such date; provided, however, that a condition to the exercise by Tenant
of such right to terminate shall be that the portion of the premises taken shall
be of such extent and nature as substantially to handicap, impede or impair
Tenant's use of the balance of the premises and that a condition to exercise by
Landlord of such right to terminate shall be that the portion of the premises
taken shall be of such extent and nature as substantially to handicap, impede or
impair Landlord's leasing or use of the balance of the premises. In the event of
any taking, Landlord shall be entitled to any and all compensation, damages,
income, rent, awards or any interest therein whatsoever which may be paid or
made in connection therewith, and Tenant shall have no claim against Landlord
except, in the event of a taking which terminates this Lease, for the value of
the then unexpired term of this Lease as if this Lease had not terminated, which
shall be valued in accordance with the same principles and assumptions used to
determine, for condemnation purposes, the value of the premises and Landlord's
interest therein. In the event of a partial taking of the premises which does
not result in a termination of this Lease, the monthly rental thereafter to be
paid shall be equitably reduced. In the event of a dispute as to the value of
Tenant's interest in the then unexpired term of this Lease, the parties shall
resolve such dispute by arbitration.

    22.  Subordination

         This Lease shall be subject and subordinated at all times to (a) all
ground or underlying leases now in effect or which may hereafter be executed
affecting the premises, and (b) the lien of all mortgages and deeds of trust in
any amount or amounts whatsoever, now or hereafter placed on or against the
premises or

                                       11                     DUPLICATE ORIGINAL

on or against Landlord's interest or estate therein or on or against all such
ground or underlying leases, all at the option of the holder(s) thereof and
without the necessity of having further instruments executed on the part of
Tenant to effectuate such subordination. Notwithstanding the foregoing; (x) in
the event of termination for any reason whatsoever of any such ground or
underlying lease, this Lease shall not be barred, terminated, cut off or
foreclosed, nor shall the rights and possession of Tenant hereunder be disturbed
if Tenant shall not then be in default in the payment of rental or other sums or
be otherwise in default under the terms of this Lease, and Tenant shall attorn
to the Landlord of any such ground or underlying lease or, if requested, enter
into a new lease for the balance of the original or extended term hereof then
remaining, upon the same terms and provisions as are in this Lease contained;
(y) in the event of a foreclosure of any such mortgage or deed of trust or of
any other action or proceeding for the enforcement thereof, or of any sale
thereunder, this Lease will not be barred, terminated, cut off or foreclosed nor
will the rights and possession of Tenant thereunder be disturbed if Tenant shall
not then be in default in the payment of rental or other sums or be otherwise in
default under the terms of this Lease, and Tenant shall attorn to the purchaser
at such foreclosure, sale or other action or proceeding; and (z) Tenant agrees
to execute and deliver, upon demand, such further instruments evidencing such
subordination of this Lease to said deed, to such ground or underlying leases,
and to the lien of any such mortgages or deeds of trust as may be reasonably
required by Landlord. Tenant's covenant to subordinate this Lease to ground or
underlying leases and mortgages or deeds of trust hereafter executed is
conditioned upon each such senior instrument containing the commitments
specified in the preceding clauses (x) and (y), and, at Tenant's request,
Landlord shall provide Tenant with written confirmation of such commitments from
the holders of instruments which, as a matter of law, are senior to this Lease
and Tenant's interest hereunder.

    23.  No Merger

         The voluntary or other surrender of this Lease by Tenant, or a mutual
cancellation thereof, shall not work a merger, and shall, at the option of
Landlord, terminate all or any existing subleases or subtenancies, or may, at
the option of Landlord, operate as an assignment to it of any or all such
subleases or subtenancies.

    24.  Sale

         In the event the Landlord hereunder, or any successor owner of the
premises, shall sell or convey the premises, or portions thereof, other than a
transfer for security purposes, all liabilities and obligations on the part of
the Landlord, or

                                       12                     DUPLICATE ORIGINAL


<PAGE>   13




such successor owner, under this Lease accruing thereafter, shall terminate, and
thereupon all such liabilities and obligations shall be binding upon the new
owner. Tenant agrees to attorn to such new owner.

    25.  Estoppel Certificate

         At any time and from time to time but on not less than ten (10) days
prior written request by Landlord, Tenant shall execute, acknowledge and deliver
to Landlord, promptly upon request, an estoppel certificate in form satisfactory
to Landlord. Any such certificate may be relied upon by any prospective
purchaser, mortgagee or beneficiary under any mortgage or deed of trust of the
premises or any part thereof.

    26.  Holding Over

         If, without objection by Landlord, Tenant holds possession of the
premises after expiration of the term of this Lease, Tenant shall become a
tenant from month to month upon the terms herein specified but at a monthly
rental equivalent to the then prevailing rental paid by Tenant at the expiration
of the term of this Lease pursuant to all the provisions of this Lease, payable
in advance on or before the first day of each month. Each party shall give the
other written notice at least one month prior to the date of termination of such
monthly tenancy of its intention to terminate such tenancy. If Tenant holds
possession of the premises after expiration of the term of this Lease,
notwithstanding Landlord's objection, Tenant shall pay monthly rental at twice
the amounts otherwise then payable under the terms hereof.

    27.  Abandonment

         Subject to applicable provisions of State and local law, if Tenant
shall abandon or surrender the premises, or be dispossessed by process of law or
otherwise, any Personal property belonging to Tenant and left on the premises
shall be deemed to be abandoned, at the option of Landlord.

    28.  Waiver

         The waiver by Landlord or Tenant of any agreement, condition or
provision herein contained shall not be deemed to be a waiver of any subsequent
breach of the same or any other agreement, condition or provision herein
contained, nor shall any custom or practice which may evolve between the parties
in the administration of the terms hereof be construed to waive or to lessen the
right of Landlord or Tenant to insist upon the performance by the other party in
strict accordance with said terms. The subsequent acceptance of rental hereunder
by Landlord shall not be deemed to be a waiver of any preceding breach by

                                       13                     DUPLICATE ORIGINAL


<PAGE>   14




Tenant of any agreement, condition or provision of this Lease, other than the
failure of Tenant to pay the particular rental so accepted, regardless of
Landlord's knowledge of such preceding breach at the time of acceptance of such
rental.

    29.  Notices

         All notices and demands which may or are required to be given by either
party to the other hereunder shall be in writing and shall be deemed to have
been fully given when deposited in the United States mail, certified or
registered, postage prepaid, and addressed as follows: To Tenant at P. O. Box
1240, Aberdeen, South Dakota 57402-1240, or to such other place as Tenant may,
from time to time, designate in a notice to Landlord; to Landlord at P. O. Box
1036, Aberdeen, South Dakota 57402-1036, or to such other place as Landlord may,
from time to time, designate in a notice to Tenant. Tenant hereby appoints as
its agent to receive the service of all dispossessory or distraint proceedings
and notices thereunder the person in charge of or occupying the premises at the
time, and if no person shall be in charge of or occupying the same, then such
service may be made by attaching the same on the main entrance of the premises.

         Tenant shall pay, before delinquency, all taxes on all real and/or
personal property belonging to, leased by, or used by Tenant on the premises,
including real estate taxes on the demised premises.

    30.  Complete Agreement

         There are no oral agreements between Landlord and Tenant affecting this
Lease, and this Lease supersedes and cancels any and all previous negotiations,
arrangements, brochures, agreements and understandings, if any, between Landlord
and Tenant with respect to the subject matter of this Lease or the premises.
There are no representations between Landlord and Tenant other than those
contained in this Lease.

    31.  Corporate Authority

         Each of the persons executing this Lease on behalf of Tenant does
hereby covenant and warrant that Tenant is a duly authorized and existing
corporation, that Tenant has and is qualified to do business in the State of
South Dakota, that the corporation has full right and authority to enter into
this Lease, and that each and every person signing on behalf of the corporation
was authorized to do so.

    32.  Mechanic's Liens.

         Tenant covenants to keep the demised premises and the improvements
thereon, at all times during the term hereof, free

                                       14                     DUPLICATE ORIGINAL

of mechanic's liens and other liens of like nature and at all times fully to
protect and indemnify Landlord against all such liens or claims which may ripen
into such liens and against all attorney's fees and other costs and expenses
growing out of or incurred by reason of or on account of any such claim or lien,
and Landlord agrees to do likewise with respect to work done by or for Landlord.
Should Tenant or Landlord fail to fully discharge any such lien or claim, the
other, at its option, may pay the same or any part thereof, and shall be the
sole judge of the legality of such lien or claim. All amounts so paid by
Landlord or Tenant, together with interest thereon at the then maximum legal
rate from time of payment until repayment, shall be repaid by the other. If the
Tenant shall desire to contest any mechanic's lien claim, it shall furnish the
Landlord adequate security in the amount of the claim or a bond of a responsible
corporate surety in such amount. If a final judgment establishing the validity
or existence of a lien for any amount is entered, the Tenant shall pay and
satisfy the same at once.

    33.  Memorandum of Lease

         A Memorandum of Lease, suitable for recording in the office of the
Register of Deeds of Brown County, State of South Dakota, and satisfactory in
form to both Landlord and Tenant, shall be executed and recorded. Said document
shall be entitled "Memorandum of Lease" and shall incorporate the legal
description of the demised premises.

    34.  Amendment and Modification

         This Lease may be modified or amended only by a writing duly authorized
and executed by both Landlord and Tenant. It may not be amended or modified by
oral agreements or understandings between the parties or by any acts or conduct
of the parties with reference thereto unless reduced to writing. The marginal
headings used herein are for convenience only and shall not be resorted to for
purposes of interpretation or construction hereof.

    35.  Successors

         All of the terms, covenants and conditions hereof shall be binding upon
and inure to the benefit of the successors and assigns of the parties hereto,
provided that nothing in this paragraph shall be deemed to permit any assignment
contrary to the provisions of Paragraph 13 above.

    36.  Miscellaneous

         The words "Landlord" and "Tenant" as used herein shall include the
plural as well as the singular. Time is of the essence of this Lease and each
and all of its provisions.

                            FIRST AMENDMENT TO LEASE

         THIS FIRST AMENDMENT TO LEASE ("Amendment") is entered into by and
among JEWETT FAMILY INVESTMENTS, L.L.C., a South Dakota limited liability
company ("Lessor") and JEWETT DRUG CO., a South Dakota corporation ("Lessee")
for the purpose of amending that certain lease, dated January 1, 1997 (the
"Lease"), by and between Lessor and Lessee respecting 217 Railroad Avenue SE,
Aberdeen, South Dakota 57402 (the "Premises"), more particularly described on
Exhibit A, attached hereto and incorporated herein.

         WHEREAS, Harvey C. Jewett, IV, sole stockholder of Lessee and managing
member of Lessor, plans to sell all of the issued and outstanding stock in
Lessee to D&K Healthcare Resources, Inc., a Delaware corporation; and

         WHEREAS, Lessee and Lessor desire to amend the Lease as per their
mutual agreement respecting the same,

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are acknowledged by each party hereto, the parties agree to
amend the Lease as follows:

         1.   Section 2(b) is hereby modified by deleting the following language
from the first sentence thereof, "two (2) separate ten-year (10-year) renewal
periods", and replacing it in its entirety by the following: "one (1) five-year
(5-year) renewal period".

         2.   The second paragraph of Section 3 is hereby deleted in its
entirety and replaced by the following: "The monthly Base Rent for the
premises is Six Thousand Six Hundred Sixty Six and 67/100 Dollars ($6,666.67)."

         3.   The fourth sentence of the first paragraph of Section 8 is hereby
deleted in its entirety and replaced by the following: "Except as otherwise
provided in the hereinafter entitled paragraph 'Destruction of Premises', Tenant
shall, at all times during the term hereof and at its sole cost and expense,
repair any and all damage to the premises; notwithstanding the foregoing, Tenant
shall have no obligation to make repairs to any structural member or major
system of the premises, including without limitation the exterior walls and
roofs thereof and the HVAC, plumbing or electrical systems thereof
(collectively, the "Excluded Repair Items"). The obligation to repair any and
all damage to Excluded Repair Items shall be the obligation of Landlord, who
shall, once such obligation arises, promptly begin the repairs thereto and
pursue such repairs diligently until completion."

         4.   The following shall be added to the end of the second paragraph of
Section 8: "Notwithstanding the foregoing, Tenant shall have no obligation to
make repairs and/or alterations to the premises required because of violation of
any governmental laws, regulations or requirements which existed on or before
June 1, 1999 (the "Excluded Alteration Items"). The obligation to make
alterations or repair any and all Excluded Alteration Items shall be the
obligation of Landlord, who shall, once such obligation arises, promptly begin
the repairs thereto and pursue such repairs


<PAGE>   2






diligently until completion."

         5.   As modified by this instrument, the Lease remains in full force
and effect.

         6.   For purposes of executing this Amendment, a document (or signature
page thereto) signed and transmitted by facsimile machine or telecopier is to be
treated as an original document. The signature of any party thereon, for
purposes hereof, is to be considered as an original signature, and the document
transmitted is to be considered to have the same binding effect as an original
signature on an original document. At the request of any party, any facsimile or
telecopy document is to be reexecuted in original form by the parties who
executed the facsimile or telecopy document. No party may raise the use of a
facsimile machine or telecopier or the fact that any signature was transmitted
through the use of a facsimile or telecopier machine as a defense to the
enforcement of this Amendment when executed in compliance with this paragraph.

         7.   This Amendment hereof may be executed in several counterparts and
by each party on a separate counterpart, each of which when so executed and
delivered shall be an original, and all of which together shall constitute one
instrument. In proving this Amendment it shall not be necessary to produce or

                                     LEASE


         THIS LEASE, dated this 1st day of July, 1997, is made and entered into
by and between JEWETT FAMILY INVESTMENTS, L.L.C., a South Dakota limited
liability company, hereinafter referred to as "Landlord", and JEWETT DRUG CO.,
A/K/A JEWETT WHOLESALE DRUG COMPANY, a South Dakota corporation, hereinafter
referred to as "Tenant".

         1. Premises

         Landlord hereby leases to Tenant, and Tenant hereby leases from
Landlord, for the term and subject to the agreements, conditions and provisions
hereinafter set forth, to each and all of which Landlord and Tenant hereby
mutually agree, all that certain real property, together with all improvements
thereon, without limitation, as follows:

         Lot A of Tract 2 of Sioux Empire Development Park Two Addition to the
         City of Sioux Falls, Minnehaha County, South Dakota, according to the
         recorded plat thereof.

For the sake of convenience, except when the context provides otherwise, the
foregoing real property and improvements are herein collectively called "the
premises", "the demised premises" or "the leased premises".

         2.   Term

         (a)  The term of this Lease shall commence on the 1st day of July,
1997, and shall end June 30, 2006.

         (b)  Tenant shall have the option to extend the term of this Lease for
not less than the entire premises leased at the end of the initial term on all
the provisions contained herein (except the renewal provisions) for two (2)
separate ten year (10-year) renewal periods by giving to Landlord notice of the
exercise of such option at least ninety (90) days prior to the expiration of The
Initial term or the initial extended term; provided, however, that if Tenant is
in default on the date of the giving of such option notice or this Lease is not
otherwise in full force and effect, the option notice shall be totally in
effective or, if Tenant is in default on the date as of which the extended term
is to commence, such extended term shall not commence and this Lease shall
expire at the end of the initial term or the initial extended term then in
effect. The Base Rent payable during the extended term(s) hereof shall be
subject to Landlord's and Tenant's agreement and in no event less than the then
prevailing rental paid by Tenant at the expiration of the initial term of this
Lease or the initial extended term, as the case may be, adjusted as of the
commencement of the extended term for which the option is exercised, both
otherwise such extended term(s) shall be upon the same terms and conditions as
set forth herein.

<PAGE>   2

         Upon adjustment of the Base Rent and any other provisions of this lease
in accordance with this Paragraph 2, the parties shall immediately execute an
amendment to this Lease stating such adjustment.

         3.   Rental

         (a)  Commencing on the Rental Commencement Date as defined in Paragraph
2(a) above, Tenant shall pay to Landlord, throughout the term of this Lease, the
following amounts as base rental for the premises (the "Base Rent") subject to
adjustment as provided in this Paragraph 3, on or before the 10th day of the
first full calendar month of the term hereof and on or before the tenth day of
each and every successive calendar month thereafter during the term hereof.

         The monthly Base Rent for the premises is Ten Thousand Dollars
($10,000.00).

         (b)  The monthly Base Rent set forth in Paragraph 3(a) above shall be
subject to adjustment annually on each anniversary of the Rental Commencement
Date (the "Adjustment Date") as follows:

         The base for computing the adjustment shall be the final Consumer Price
Index for all Urban Consumers in the United States published by the United
States Department of Labor, Bureau of Labor Statistics (the "Index"), which is
published for the month most recently preceding the Rental Commencement Date
("Beginning Index"). If the Index published most recently preceding an
Adjustment Date ("Adjustment Index") has increased or decreased with respect to
the Beginning Index, the monthly Base Rent for the period until the next annual
Adjustment Date shall be set by multiplying the monthly Base Rental by a
fraction, the numerator of which is the Adjustment Index and the denominator of
which is the Beginning Index. In no case shall the monthly Base Rent be less
than the full monthly Base Rent set forth in Paragraph 3(a). On adjustment of
the monthly Base Rent as provided in this Lease, the parties shall immediately
execute an amendment to the Lease stating the new monthly Base Rent.

         If the Index is changed so that the base year differs from that used as
of the month most recently preceding the month in which the term commences, the
Index shall be converted in accordance with the conversion factor published by
the United States Department of Labor, Bureau of Labor Statistics. If the Index
is discontinued or revised during the term, such other government index or
computation with which it is replaced shall be used in order to obtain
substantially the same result as would be obtained if the Index has not be
discontinued or revised.

         4. Absolutely Net Lease

         The parties understand and agree that this Lease is deemed an
absolutely net lease wherein Tenant shall pay and be responsible for all
premises expenses and operating costs including, without limitation, all present
and future costs of any kind paid or incurred in operating, cleaning, equipping,
protecting, lighting, repairing, heating, air-conditioning and maintaining the
premises.

         5.   Taxes, Assessments and Public Utilities

         Tenant shall pay for all water, light, power, gas, heat, rubbish
removal, telephone service and all other services and utilities supplied now and
in the future to the demised premises and Landlord shall have no responsibility
therefor.

         In addition to the monthly rental and other charges to be paid by
Tenant hereunder, Tenant shall reimburse Landlord, upon demand, for any and all
taxes payable by Landlord (other than net income taxes) whether or not now
customary or within the contemplation of the parties hereto: (a) upon, measured
by or reasonably attributable to the cost or value of Tenant's equipment,
furniture, fixtures and other personal property located in the premises or by
the cost or value of any leasehold improvements made in or to the premises by or
for Tenant, regardless of whether title to such improvements shall be in Tenant
or Landlord; (b) upon or measured by the monthly rental payable hereunder
including, without limitation, any gross receipts tax or excise tax levied by
the City of Aberdeen, the County of Brown, the State of South Dakota, the
Federal Government or any other governmental body with respect to the receipt of
such rental; (c) upon or with respect to the possession, leasing, operation,
management, maintenance, alteration, repair, use or occupancy by Tenant of the
premises or any portion thereof.  If it shall not be lawful for Tenant so to
reimburse Landlord, the monthly rental payable to Landlord under this Lease
shall be revised to net Landlord the same net rental after imposition of any
such tax upon Landlord as would have been payable to Landlord before the
imposition of any such tax. All taxes and assessments payable for a period
partly within and partly without the term of this Lease shall be prorated
between Landlord and Tenant.

         Tenant shall pay, before delinquency, all taxes on all personal
property belonging to or used by Tenant on the premises.

         6.   Use of Premises

         Tenant agrees that the demised premises shall be used and occupied only
as a wholesale warehouse and office facility and for no other purpose or
purposes without Landlord's prior written consent. Tenant shall not do or permit
to be done in or about the premises, nor bring or keep or permit to be brought
or kept therein, anything which is prohibited by or will in any way conflict
with any law, statute, ordinance or governmental rule or regulation now in force
or which may hereafter be enacted or promulgated, or which is prohibited by any
fire insurance policy covering the premises, or will in any way increase the
rate of or affect any fire or other insurance upon the premises or any of its
contents beyond those normally 'in effect for use as a wholesale warehouse and
office facility, or cause a cancellation of any insurance policy covering the
premises or any part thereof or any of its contents. Tenant shall not do or
permit anything to be done in or about the premises for any unlawful purpose,
nor shall Tenant cause, maintain or permit any nuisance in, on or about the
premises or commit or suffer to be committed any waste in, on or about the
premises.

         7.  Fixtures and Equipment

         Tenant may install in the demised premises, at its own cost and
expense, any fixtures, equipment and signs it deems necessary in addition to
furniture, fixtures and equipment leased herein, for the conduct of said
business, which fixtures, equipment and signs may either be leased by Tenant or
purchased by Tenant from a conditional seller or otherwise. Landlord shall not
be responsible for the safekeeping of any such fixtures, equipment or other
goods. All furniture, fixtures, equipment and signs installed by Tenant in or
about the demised premises shall, at all times, be and remain personal property,
regardless of the method in which the same is affixed to the demised premises,
and shall remain the personal property of the Tenant.


         8.   Maintenance and repairs

         By entry hereunder, Tenant accepts the premises as being in the
condition in which Landlord is obligated to deliver the premises. Landlord has
no obligation and has made no promise to alter, remodel, improve, repair,
decorate or paint the premises or any part thereof. No representations
respecting the condition of the premises have been made by Landlord to Tenant,
except as specifically set forth in this Lease. Except as otherwise provided in
the hereinafter entitled paragraph "Destruction of Premises", Tenant, at all
times during the term hereof and at its condition and repair including, without
limitation, the roof and all exterior walls, all landscaped areas and parking
lots. Tenant agrees, at the expiration of this Lease or upon the earlier
termination thereof, to quit and surrender the leased premises in good condition
and repair, ordinary wear and damage by act of God or war or other causes beyond
the control of Tenant excepted.

         Tenant, at its sole cost and expense, shall promptly comply with all
present and future governmental requirements pertaining to the use or occupancy
of the premises. Tenant hereby waives all rights to make repairs at the expense
of the Landlord or in lieu thereof to vacate the premises.

         9.   Insurance

         Tenant shall obtain and maintain in full force during the term hereof,
at its own expense, public liability insurance in minimum amounts of $1,000,000
for injury or death of one person, $1,000,000 for injury or death arising out of
any one occurrence, and $350,000 for damage to property, such coverage to
protect the Tenant and Landlord and any such other persons, firms or
corporations as are designated by Landlord.

         Tenant shall also obtain and maintain in full force during the term
hereof at its own expense, fire, extended coverage and special form insurance on
the improvements on the leased premises in an amount equal to not less than one
hundred percent (100%) of the actual replacement cost (exclusive of foundation
and excavation costs) of such improvements, which insurance shall name Landlord
and Tenant as co-insureds and shall contain a loss-payable endorsement in favor
of the beneficiary of any mortgage covering the subject real property and
provide that such policies cannot be cancelled without thirty (30) days prior
notice to such parties.

<PAGE>   5




         Tenant, at its expense, shall maintain for the benefit of landlord
so-called rental value insurance, protecting the Landlord from loss of rent or
income occasioned by damages to the premises as covered by such policies of
insurance, such loss of income to be guaranteed for a period of six (6) months
from the date of occurrence of the damage, in the full amount of all rentals due
and payable under Paragraph 3 above.

         Each party hereby waives its entire right of recovery against the other
party for losses which are insured against under-insured policies carried by
each of such parties to the extent expressly permitted by the issuers of such
insurance policies.

         All policies of insurance which Tenant is required to carry hereunder
shall be issued by good and responsible companies authorized to write such
insurance in South Dakota and shall provide that no cancellation or material
change in the coverage shall be made except after thirty (30) days prior notice
to Landlord. Tenant may, at its option, satisfy its obligations under this
paragraph by bringing said risks within the coverage of any so-called blanket
policy or policies of insurance which it may now or hereafter carry by an
appropriate amendment, rider, endorsement or otherwise so long as Landlord is
provided a certificate establishing that the coverage allocated to the premises
is in compliance with the terms of this Lease. Copies of all insurance policies
required under the provisions of this Lease shall be delivered to Landlord
punctually.

         10.  Indemnification

         Tenant hereby waives all claims against Landlord for damage to any
property or injury to or death of any person in, upon or about the premises
arising at any time and from any cause except to the extent that such is caused
by the sole and exclusive negligence or willful misconduct of Landlord. Tenant
shall hold Landlord harmless from any damage to any property or injury to or
death of any person arising from the use of the premises by Tenant, except to
the extent that such is caused by the sole and exclusive negligence or willful
misconduct of Landlord and, to such extent, Landlord agrees to hold Tenant
harmless from any such damage, injury or death. The foregoing indemnity
obligations shall include actual attorneys' fees paid or incurred in good faith,
investigation costs and all other reasonable costs and expenses incurred by the
party indemnified from the first notice that any claim or demand is to be made
or may be made. The provisions of this Paragraph 10 shall survive the
termination of this Lease with respect to any damage, injury or death occurring
before such termination.

         11.  Damage and Destruction of Premises

         In the event of a total or partial destruction of the improvements
constructed on the leased premises during the term of the Lease, from any cause
covered by the insurance described in Paragraph 9 of the Lease, Tenant shall
promptly repair the same, but such destruction shall not annul or void the
Lease; provided that the holder of any encumbrance makes the insurance proceeds
available to Tenant or in lieu thereof, the lender may hold said proceeds in
trust to be distributed to Tenant, or Tenant's subcontractors as the work
progresses and Tenant delivers certification of the same. The proceeds received
from the rental value insurance described in said Paragraph 9 shall be paid to
Landlord during the six (6) month period covered by said insurance but,
subsequent to said

                                       5                     DUPLICATE ORIGINALS

date, the rent reserved to be paid hereunder shall be equitably adjusted
according to the amount and value of the undamaged space. Notwithstanding the
provisions of this Paragraph 11, in the event there is total destruction, or
partial destruction of the extent of fifty percent cent (50%) or more of the
improvements constructed on the leased premises during the last one hundred
twenty (120) days of the initial term, or during the last one hundred twenty
(120) days of the extended term under any option to extend this Lease, Tenant
can elect to terminate this Lease by written notice delivered to Landlord not
more than thirty (30) days after the destruction or damage, provided that in the
event Tenant elects to so terminate, the insurance proceeds payable under the
insurance described in Paragraph 9 shall be the property of the Landlord.

         In the event of damage or destruction by any casualty other than a
casualty insured under the insurance referred to hereinabove, Landlord may
restore the premises or, at Landlord's option, may elect to terminate the Lease
and thereupon be released from further obligation under the Lease by giving
written notice thereof to Tenant within twenty (20) days after the occurrence of
such casualty, unless Tenant elects to restore the premises, by written notice
of such election to Landlord, delivered to Landlord within twenty (20) days
after the receipt of Landlord's written election to terminate the Lease, in
which event Tenant shall, as soon as reasonably possible, commence and proceed
diligently to restore the premises substantially to the condition thereof
immediately prior to such damage or destruction. If neither party elects to
restore the improvements, the Lease shall be terminated and thereupon the
Landlord and Tenant shall be released from further obligation thereunder, except
that Landlord shall be obligated to repay Tenant any unused prepaid rent paid to
Landlord.

         12.  Alterations

         Tenant shall not make, or suffer to be made, any alterations, additions
or improvements to or of the premises or any part thereof, without the prior
written consent of the Landlord. Any alterations, additions or improvements to
the premises shall be for Tenant's account on the basis of plans and
specifications approved by Landlord and shall become at once a part of the
realty and shall belong to the Landlord without compensation. If written consent
of the Landlord to any such proposed repairs or alterations by Tenant shall have
been obtained, Tenant agrees to advise Landlord in writing of the date upon
which such repairs or alterations will commence in order to permit Landlord to
post a notice of non-responsibility. Tenant agrees to save and hold Landlord
free and harmless against any liability, loss or damage (and to defend Landlord
by attorneys of Tenant's selection, at Tenant's sole expense) on account of any
mechanic's lien claim for work performed or materials furnished in connection
with such alterations.

         13.  Assignment and Subletting

         Tenant shall not either voluntarily, or by operation of law, assign,
transfer, mortgage, pledge, hypothecate or encumber this Lease or any interest
therein or in the shares of Tenant, and shall not sublet the premises or any
part thereof, or any right or privilege appurtenant thereto, or allow any other
person (the employees, agents, servants and invitees of Tenant excepted) to
occupy or use the premises, or any portion thereof, without first obtaining the
written consent of Landlord, which consent shall not be unreasonably withheld. A
consent to one assignment,

<PAGE>   7


subletting, occupation or use shall not be deemed to be a consent to any
subsequent assignment, subletting, occupation or use.  Consent to any such
assignment or subletting shall in no way relieve Tenant of any liability under
this Lease.  Any such assignment or subletting without such consent, whether
direct or indirect, shall be void and shall, at the option of the Landlord,
constitute a default under the terms of this Lease.

         In the event that Landlord shall consent to a sublease or assignment
hereunder, Tenant shall pay Landlord all reasonable fees, not to exceed Five
Thousand Dollars ($5,000.00), incurred in connection with the processing of
documents necessary to the giving of such consent.

         14.  Quiet Enjoyment

         The Tenant, upon paying the rent herein provided and performing all and
singular the covenants and conditions of the Lease on its part to be performed,
shall and may peaceably and quietly have, hold and enjoy legal possession to the
demised premises during the term hereof.

         15.  Events of Default

         The occurrence of any one or more of the following events ("Events of
Default") shall constitute a breach of this Lease by Tenant: (a) if Tenant shall
fail to pay any rental when and as the same becomes due and payable and such
failure shall continue for more than three (3) days after Tenant receives notice
of nonpayment from Landlord; or (b) if Tenant shall fail to pay any other sum
when and as the same becomes due and payable and such failure shall continue for
more than ten (10) days after Tenant receives notice of nonpayment from
Landlord; or (c) if Tenant shall fail to perform or observe any other term
hereof to be performed or observed by Tenant, such failure shall continue for
more than thirty (30) days after Tenant receives notice thereof from Landlord,
and Tenant shall not, within such period, commence with due diligence and
dispatch the curing of such default or, having so commenced, shall thereafter
fail or neglect to prosecute or complete with due diligence and dispatch the
curing of such default; or (d) if Tenant shall make a general assignment for the
benefit of creditors, or shall admit in writing its inability to pay its debts
as they become due, or shall file a petition in bankruptcy, or shall be
adjudicated as bankrupt or insolvent, or shall file a petition in any proceeding
seeking any reorganization, arrangement, composition, readjustment, liquidation,
dissolution or similar relief under any present or future statute, law or
regulation, or shall file an answer admitting or fail timely to contest the
material allegations of a petition filed against it in any such proceeding, or
shall seek or consent to or acquiesce in the appointment of any trustee,
receiver or liquidator of Tenant or any material part of its properties; or (e)
if within sixty (60) days after the commencement of any proceeding against
Tenant seeking any reorganization, arrangement, composition, readjustment,
liquidation, dissolution or similar relief under any present or future statute,
law or regulation, such proceeding shall not have been dismissed, or if, within
sixty (60) days after the appointment without the consent or acquiescence of
Tenant, of any trustee, receiver or liquidator of Tenant or of any material part
of its properties, such appointment shall not have been vacated; or (f) if this
Lease or any estate of Tenant hereunder shall be levied upon under any
attachment or execution and such attachment or execution is not vacated within
ten (10) days.

<PAGE>   8
         16.    Termination Upon Default

         If an Event of Default shall occur, Landlord at any time thereafter may
give a written termination notice to Tenant, and on the date specified in such
notice (which shall be not less than three (3) days after the giving of such
notice) Tenant's right to possession shall terminate and this Lease shall
terminate, unless on or before such date all arrears of rental and all other
sums payable by Tenant under this Lease (together with interest thereon at the
then maximum legal rate) and all costs and expenses incurred by or on behalf of
Landlord hereunder shall have been paid by Tenant and all other breaches of this
Lease by Tenant at the time existing shall have been fully remedied to the
satisfaction of Landlord. Upon such termination, Landlord may accumulatively
recover from Tenant: (a) the worth at the time of award of the unpaid rental
which had been earned at the time of termination; and (b) the worth at the time
of award of the amount by which the unpaid rental which would have been earned
after termination until the time of award exceeds the amount of such rental loss
that Tenant proves could have been reasonably avoided; and (c) the worth at the
time of award of the amount by which the unpaid rental for the balance of the
term of this Lease after the time of award exceeds the amount of such rental
loss that Tenant proves could be reasonably avoided; and (d) any other amount
necessary to compensate Landlord for all the detriment proximately caused by
Tenant's failure to perform its obligations under this Lease or which, in the
ordinary course of events, would be likely to result therefrom. The "worth at
the time of award" of the amounts referred to in clauses (a) and (b) above shall
be computed by allowing interest at the then maximum legal rate. The worth at
the time of award of the amount referred to in clause (c) above shall be
computed by discounting such amount at the discount rate of the Federal Reserve
Bank of Minneapolis, Minnesota at the time of award plus one percent (1%). For
the purpose of determining unpaid rental under clauses (a), (b) and (c) above,
the monthly rent reserved in this Lease shall be deemed to be the sum of the
amounts last payable by Tenant pursuant to Paragraph 3 above.

         17.  Continuation After Default

         Even though Tenant has breached this Lease and abandoned the premises,
this Lease shall continue in effect for so long as Landlord does not expressly
terminate, in writing, Tenant's right to possession, and Landlord may enforce
all its rights and remedies under this Lease, including the right to recover the
rental as it becomes due under this Lease. Acts of maintenance, preservation,
efforts to relet the premises or the appointment of a receiver upon the
initiative of Landlord to protect Landlord's interest under this Lease shall not
constitute a termination of Landlord's right to possession.

         18.  Other Relief

         The remedies provided for in this Lease are in addition to any other
remedies available to Landlord at law or in equity by statute or otherwise.

         19. Landlord's Right to Cure Defaults

         All agreements and provisions to be performed by Tenant under any of
the terms of this Lease shall be at its sole cost and expense and without any
abatement of rental. If Tenant shall fail to pay any sum of money and such
failure is unexcused under the terms hereof, other than rental required to be
paid by it hereunder, or shall fail to perform any other act on its part to be
performed hereunder and such failure shall continue for thirty (30) days after
notice thereof by Landlord, Landlord may, but shall not be obligated so to do
and without waiving or releasing Tenant from any obligations of Tenant, make any
such payment or perform any such other act on Tenant's part to be made or
performed as in this Lease provided. All sums so paid by Landlord and all
necessary incidental costs shall be deemed additional rent hereunder and shall
be payable to Landlord on demand, and Landlord shall have (in addition to any
other right or remedy of Landlord) the same rights and remedies in the event of
the nonpayment thereof by Tenant as in the case of default by Tenant in the
payment of rental.

         20.  Attorney's Fees

         In the event of any action or proceeding brought by either party
against the other under this Lease, the prevailing party in any final judgment
or the nondismissing party in the event of a dismissal without prejudice shall
be entitled to the full amount of all reasonable expenses including all costs
and actual attorney's fees paid or incurred in good faith in connection
therewith.

         21.  Eminent Domain

         If all or any part of the premises shall be taken as a result of the
exercise of the power of eminent domain, this Lease shall terminate as to the
part so taken as of the date of taking and in the case of a partial taking,
either Landlord or Tenant shall have the right to terminate this Lease as to the
balance of the premises by written notice to the other within thirty (30) days
after such date; provided, however, that a condition to the exercise by Tenant
of such right to terminate shall be that the portion of the premises taken shall
be of such extent and nature as substantially to handicap, impede or impair
Tenant's use of the balance of the premises and that a condition to exercise by
Landlord of such right to terminate shall be that the portion of the premises
taken shall be of such extent and nature as substantially to handicap, impede or
impair Landlord's leasing or use of the balance of the premises. In the event of
any taking, Landlord shall be entitled to any and all compensation, damages,
income, rent, awards or any interest therein whatsoever which may be paid or
made in connection therewith, and Tenant shall have no claim against Landlord
except, in the event of a taking which terminates this Lease, for the value of
the then unexpired term of this Lease as if this Lease had not terminated, which
shall be valued in accordance with the same principles and assumptions used to
determine, for condemnation purposes, the value of the premises and Landlord's
interest therein. In the event of a partial taking of the premises which does
not result in a termination of this Lease, the monthly rental thereafter to be
paid shall be equitably reduced. In the event of a dispute as to the value of
Tenant's interest in the then unexpired term of this Lease, the parties shall
resolve such dispute by arbitration.

         22. Subordination

         This Lease shall be subject and subordinated all times to (a) all
ground or underlying leases now in effect or which may hereafter be executed
affecting the premises, and (b) the lien of all mortgages and deeds of trust in
any amount or amounts whatsoever, now or hereafter placed on or against the
premises or on or against Landlord's interest or estate therein or on or against
all such ground or underlying leases, all at the option of the holder(s) thereof
and without the necessity of having further instruments executed on the part of
Tenant to effectuate such subordination. Nothwithstanding the foregoing; (x) in
the event of termination for any reason whatsoever of any such ground or
underlying lease, this Lease shall not be barred, terminated, cut off or
foreclosed, nor shall the rights and possession of Tenant hereunder be disturbed
if Tenant shall not then be in default in the payment of rental or other sums or
be otherwise in default under the terms of this Lease, and Tenant shall attorn
to the Landlord of any such ground or underlying lease or, if requested, enter
into a new lease for the balance of the original or extended term hereof then
remaining, upon the same terms and provisions as are in this Lease contained;
(y) in the event of a foreclosure of any such mortgage or deed of trust or of
any other action or proceeding for the enforcement thereof, or of any sale
thereunder, this Lease will not be barred, terminated, cut off or foreclosed nor
will the rights and possession of Tenant thereunder be disturbed if Tenant shall
not then be in default in the payment of rental or other sums or be otherwise in
default under the terms of this Lease, and Tenant shall attorn to the purchaser
at such foreclosure, sale or other action or proceeding; and (z) Tenant agrees
to execute and deliver, upon demand, such further instruments evidencing such
subordination of this Lease to said deed, to such ground or underlying leases,
and to the lien of any such mortgages or deeds of trust as may be reasonably
required by Landlord. Tenant's covenant to subordinate this Lease to ground or
underlying leases and mortgages or deeds of trust hereafter executed is
conditioned upon each such senior instrument containing the commitments
specified in the preceding clauses (x) and (y), and, at Tenants request,
Landlord shall provide Tenant with written confirmation of such commitments from
the holders of instruments which, as a matter of law, are senior to this Lease
and Tenant's interest hereunder.

         23.  No Merger

         The voluntary or other surrender of this Lease by Tenant, or a mutual
cancellation thereof, shall not work a merger, and shall, at the option of
Landlord, terminate all or any existing subleases or subtenancies, or may, at
the option of Landlord, operate as an assignment to it of any or all such
subleases or subtenancies.

         24.  Sale

         In the event the Landlord hereunder, or any successor owner of the
premises shall sell or convey the premises, or portions thereof, other than a
transfer for security purposes, all liabilities and obligations on the part of
the Landlord, or such successor owner, under this Lease accruing thereafter,
shall terminate, and thereupon all such liabilities and obligations shall be
binding upon the new owner. Tenant agrees to attorn to such new owner.

         25.  Estoppel Certificate

         At any time and from time to time but on not less than ten (10) days
prior written request by Landlord, Tenant shall execute, acknowledge and deliver
to Landlord, promptly upon request, an estoppel certificate in form satisfactory
to Landlord. Any such certificate may be relied upon by any prospective
purchaser, mortgagee or beneficiary under any mortgage or deed of trust of the
premise or any part thereof.

         26.  Holding Over

         If, without objection by Landlord, Tenant holds possession of the
premises after expiration of the term of this Lease, Tenant shall become a
tenant from month to month upon the terms herein specified but at a monthly
rental equivalent to the then prevailing rental paid by Tenant at the expiration
of the term of this Lease pursuant to all the provisions of this Lease, payable
in advance on or before the first day of each month. Each party shall give the
other written notice at least one month prior to the date of termination of such
monthly tenancy of its intention to terminate such tenancy. If Tenant holds
possession of the premises after expiration of the term of this Lease,
notwithstanding Landlord's objection, Tenant shall pay monthly rental at twice
the amounts otherwise then payable under the terms hereof.

         27.  Abandonment

         Subject to applicable provisions of State and local law, if Tenant
shall abandon or surrender the premises, or be dispossessed by process of law or
otherwise, any personal property belonging to Tenant and left on the premises
shall be deemed to be abandoned, at the option of Landlord.

         28.  Waiver

         The waiver by Landlord or Tenant of any agreement, condition or
provision herein contained shall not be deemed to be a waiver of any subsequent
breach of the same or any other agreement, condition or provision herein
contained, nor shall any custom or practice which may evolve between the parties
in the administration of the terms hereof be construed to waive or to lessen the
right of Landlord or Tenant to insist upon the performance by the other party in
strict accordance with said terms. The subsequent acceptance of rental hereunder
by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant
of any agreement, condition or provision of this Lease, other than the failure
of Tenant to pay the particular rental so accepted, regardless of Landlord's
knowledge of such preceding breach at the time of acceptance of such rental.

         29.  Notices

         All notices and demands which may or are required to be given by either
party to the other hereunder shall be in writing and shall be deemed to have
been fully given when deposited in the United States mail, certified or
registered, postage prepaid, and addressed as

follows: To Tenant at P.O. Box 1240, Aberdeen, South Dakota 57402-1240, or to
such other place as Tenant may, from time to time, designate in a notice to
Landlord; to Landlord at P.O. Box 1036, Aberdeen, South Dakota 57402-1036, or to
such other place as Landlord may, from time to time, designate in a notice to
Tenant.  Tenant hereby appoints as its agent to receive the service of all
dispossessory or distraint proceedings and notices thereunder the person in
charge of or occupying the premises at the time, and if no person shall be in
charge of or occupying the same, then such service may be made by attaching the
same on the main entrance of the premises.

         Tenant shall pay, before delinquency, all taxes on all real and/or
personal property belonging to, leased by, or used by Tenant on the premises,
including real estate taxes on the demised premises.

         30.  Complete Agreement

         There are no oral agreements between Landlord and Tenant affecting this
Lease, and this Lease supersedes and cancels any and all previous negotiations,
arrangements, brochures, agreements and understandings, if any, between Landlord
and Tenant with respect to the subject matter of this Lease or the premises.
There are no representations between Landlord and Tenant other than those
contained in this Lease.

         31.  Corporate Authority

         Each of the persons executing this Lease on behalf of Tenant does
hereby covenant and warrant that Tenant is a duly authorized and existing
corporation, that Tenant has and is qualified to do business in the State of
South Dakota, that the corporation has full right and authority to enter into
this Lease, and that each and every person signing on behalf of the corporation
was authorized to do so.

         32.  Mechanic's Liens

         Tenant covenants to keep the demised premises and the improvements
thereon, at all times during the term hereof, free of mechanic's liens and other
liens of like nature and at all times fully to protect and indemnify Landlord
against all such liens or claims which may ripen into such liens and against all
attorney's fees and other costs and expenses growing out of or incurred by
reason of or on account of any such claim or lien, and Landlord agrees to do
likewise with respect to work done by or for Landlord. Should Tenant or Landlord
fail to fully discharge any such lien or claim, the other, at its option, may
pay the same or any part thereof, and shall be the sole judge of the legality of
such lien or claim. All amounts so paid by Landlord or Tenant, together with
interest thereon at the then maximum legal rate from time of payment until
repayment, shall be repaid by the other. If the Tenant shall desire to contest
any mechanic's lien claim, it shall furnish the Landlord adequate security in
the amount of the claim or a bond of a responsible corporate surety in such
amount. If a final judgment establishing the validity or existence of a lien for
any amount is entered, the Tenant shall pay and satisfy the same at once.

                            FIRST AMENDMENT TO LEASE


         THIS FIRST AMENDMENT TO LEASE ("Amendment") is entered into by and
among JEWETT FAMILY INVESTMENTS, L.L.C., a South Dakota limited liability
company ("Lessor") and JEWETT DRUG CO., a South Dakota corporation ("Lessee")
for the purpose of amending that certain lease, dated July 1, 1997 (the
"Lease"), by and between Lessor and Lessee respecting 807 Benson Road, Sioux
Falls, South Dakota 57105 (the "Premises"), more particularly described on
Exhibit A, attached hereto and incorporated herein.


         WHEREAS, Harvey C. Jewett, IV, sole stockholder of Lessee and managing
member of Lessor, plans to sell all of the issued and outstanding stock in
Lessee to D&K Healthcare Resources, Inc., a Delaware corporation; and

         WHEREAS, Lessee and Lessor desire to amend the Lease as per their
mutual agreement respecting the same.

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are acknowledged by each party hereto, the parties agree to
amend the Lease as follows:

         1.   Section 2(b) is hereby modified by deleting the following language
from the first sentence thereof, "two (2) separate ten-year (10-year) renewal
periods", and replacing it in its entirety by the following: "one (1) five-year
(5-year) renewal period".

         2.   The fourth sentence of the first paragraph of Section 8 is hereby
deleted in its entirety and replaced by the following: "Except as otherwise
provided in the hereinafter entitled paragraph 'Destruction of Premises', Tenant
shall, at all times during the term hereof and at its sole cost and expense,
repair any and all damage to the premises; notwithstanding the foregoing, Tenant
shall have no obligation to make repairs to any structural member or major
system of the premises, including without limitation the exterior walls and
roofs thereof and the HVAC, plumbing or electrical systems thereof
(collectively, the "Excluded Repair Items"). The obligation to repair any and
all damage to Excluded Repair Items shall be the obligation of Landlord, who
shall, once such obligation arises, promptly begin the repairs thereto and
pursue such repairs diligently until completion."

         3.   The following shall be added to the end of the second paragraph of
Section 8: "Notwithstanding the foregoing, Tenant shall have no obligation to
make repairs and/or alterations to the premises required because of violation of
any governmental laws, regulations or requirements which existed on or before
June 1, 1999 (the "Excluded Alteration Items"). The obligation to alter or
repair any and all Excluded Alteration Items shall be the obligation of
Landlord, who shall, once

<PAGE>   2




such obligation arises, promptly begin the repairs thereto and pursue such
repairs diligently until completion."

          4.  The following shall be added as Section 37 of the Lease: "Landlord
hereby covenants and agrees that it will, on or before                ,        ,
begin construction of an addition to the premises (the "Addition"). The Addition
shall (i) at a minimum, result in a total facility square footage, including the
existing premises, of 20,000 square feet, (ii) be constructed in accordance with
plans and specifications to be mutually agreed upon by the parties and (iii) be
constructed with materials and workmanship equal to the existing premises. All
costs and expenses associated with the construction of the Addition shall be
borne by Landlord. The Landlord shall procure or caused to be procured insurance
in commercially reasonable amounts to cover the risks normally associated with
the construction of a like building or addition, and shall indemnify, defend and
hold harmless the Tenant for any and all lost, cost and damage associated with
the construction of the Addition (but not special or consequential damages),
including and notwithstanding anything to contrary herein contained, mechanic's
liens."

         5.   For purposes of executing this Amendment, a document (or signature
page thereto) signed and transmitted by facsimile machine or telecopier is to be
treated as an original document. The signature of any party thereon, for
purposes hereof, is to be considered as an original signature, and the document
transmitted is to be considered to have the same binding effect as an original
signature on an original document. At the request of any party, any facsimile or
telecopy document is to be reexecuted in original form by the parties who
executed the facsimile or telecopy document. No party may raise the use of a
facsimile machine or telecopier or the fact that any signature was transmitted
through the use of a facsimile or telecopier machine as a defense to the
enforcement of this Amendment when executed in compliance with this paragraph.

         6.   This Amendment hereof may be executed in several counterparts and
by each party on a separate counterpart, each of which when so executed and
delivered shall be an original, and all of which together shall constitute one
instrument. In proving this Amendment it shall not be necessary to produce or
account for more than one such counterpart signed by the party against whom
enforcement is sought.

   As modified by this instrument, the Lease remains in full force and effect.

                             PRIME VENDOR AGREEMENT


This agreement is made as of the 21st day of March 1994, between TEL-DRUG, INC.
also known as CIGNA and JEWETT DRUG CO., INC. of Aberdeen, South Dakota,
hereinafter known as JDC.

1.   PRIME VENDOR

     The following describe the terms and conditions under which JDC, as a prime
     vendor, will provide pharmaceutical products and services to Tel-Drug.

2.   TERMS AND CONDITIONS

     A.   PRICE STRUCTURE

          JDC will supply all products under this agreement to Tel-Drug on the
          basis of the "cost" (as that term is defined an following page)
          plus [*}

          For purchases of non-contract product, "Cost" will be defined as the
          manufacturer's published wholesale acquisition cost on the date of
          JDC's invoice to Tel-Drug, adjusted to reflect normal and customary
          quantity discounts and special promotional allowances, excluding
          manufacturer's cash discounts. For purchases of contract product,
          "Cost" will be defined as the cost negotiated between the manufacturer
          and Tel-Drug; provided that JDC shall have an arrangement with the
          manufacturer regarding such contract cost satisfactory to JDC. The

                    first choice contract products ordered by Tel-Drug.

     D.   CONTRACT LOAD INFORMATION

          JDC loads bid files in the following manner in order to ensure initial
          and ongoing accuracy. Six weeks lead time is requested in order to
          complete this process before the membership begins purchasing.

          -    JDC loads the file electronically or manually depending on how
               the data is provided by CIGNA. JDC loads the file based on data
               provided by CIGNA.

          -    After the file is loaded, JDC will validate the accuracy of the
               entire file by comparing the file to hard copy contracts provided
               to JDC by the manufacturer.

               Approximately 80% of the vendors provide the data in hard copy.

          -    JDC will identify those manufacturers that do not provide hard
               copy verification. JDC will interact with the manufacturers and
               CIGNA in an aggressive effort to secure hard copy verification.

          -    Price discrepancies identified in the above process will be
               brought to the attention of the manufacturer and CIGNA in order
               to determine the correct price.

          -    JDC will load contract updates on the same day that the

               the facility.

          3.   To maintain the integrity of such products and to reduce any
               risks associated with such products to those receiving them, JDC
               will ship within a separate package all chemotherapeutic agents

               most recent date relating to this issue.

          Service Level

          JDC will guarantee a 96% line service level for each facility. Should
          the service level for my facility fall below 96% for two consecutive
          months, JDC will rebate such facility an amount equal to 0.1% of such
          facility's purchases during each subsequent month in which the line
          service level remains below 96%.

          The following provisions will apply:

          1.   Purchases must not exceed 120% of the prior month.

          2.   One month start up for new items. Excluding bid year transition.

          3.   CIGNA must submit bid awards a minimum of six weeks prior to bid

               generated by JDC.

          5.   The service level promise will not apply to new items; provided,
               however, that JDC will use commercially reasonable efforts to
               have items in stock as soon as possible after orders are placed
               by the facility.

          6.   Manufacturers' back orders, and re-orders of a product that occur
               within three (3) days of the initial order of the product
               hereunder, will not be counted in the service level calculation.

          7.   Partial line fills of orders will be counted as a percentage of
               the total line item filled. For example, if ten (10) pieces of
               one (1) item are ordered and one piece is delivered, the item
               will be counted as ten percent (10%) filled.

                     IO   =   total number of items ordered

                              lines)
                     CS   =   out of stocks or shorts due to manufacturer;

         ADDENDUM III to Prime Vendor Agreement (the "Agreement") dated March
         21, 1994, between Tel-Drug, Inc. ("Tel-Drug") and Jewett Drug Company,
         Inc. ("JDC") of Aberdeen, South Dakota.

         Tel-Drug and JDC agree to amend the Agreement as follows:

         1.   The effective date of this Amendment shall be       6-1-97
                                                            --------------------

         2.   Section 2. of the Agreement is deleted in its entirety and
              replaced with the following:

         2.        TERMS AND CONDITIONS

                   A.    PRICE STRUCTURE

                         JDC will supply all products under this agreement to
                         Tel-Drug on the basis of the "cost", which is defined
                         as follows:

                         For Non Contracted Products
                         "Cost" is defined as the manufacturer's published
                         wholesale acquisition cost on the date of JDC's invoice
                         to Tel-Drug, plus additional adjustments to reflect
                         normal and customary quantity discounts and special
                         promotional allowances, excluding manufacturer's cash
                         discounts.

                         For Contract Products
                         "Cost" is defined as the cost negotiated between the
                         manufacturer and Tel-Drug; provided that JDC shall have
                         an arrangement with the manufacturer regarding such
                         contract cost satisfactory to JDC. The FDC system
                         pricing logic is defined as best price. If a special
                         promotional price is more Favorable than the contract
                         price, the product will be priced at the lower amount.

                         All orders must be electronically transmitted to
                         qualify for above pricing. Non-transmitted orders
                         subject to cost plus* (excluding schedule II's, back
                         orders and emergency orders).

                         Additional Volume Discounts
                         JDC will allow additional credits in the form of volume
                         discount percentages to Tel-Drug monthly based on
                         Tel-Drug's monthly net purchase volume with JDC. Such
                         credit for additional volume shall be in the form of a
                         check, payable to Tel-Drug (the "Payment") which shall
                         be delivered to Tel-Drug by the tenth (10th) working
                         day of each month. The amount of the Payment to Tel-

         Addendum V to Prime Vendor Agreement (the "Agreement") dated March
         21, 1994, between Tel-Drug, Inc. ("Tel-Drug") and Jewett Drug Company,
         Inc. ("JDC") of Aberdeen, South Dakota.

         Tel-Drug and JDC agree to amend the Agreement as follows:

         1.   The effective date of this Amendment shall be 12-1-98.


         2.   Section 2. of the Agreement is deleted in its entirety and
              replaced with the following.

         2.   TERMS AND CONDITIONS

              A.   PRICE STRUCTURE

                   JDC will supply all products under this agreement to Tel-Drug
                   on the basis of the "cost", which is defined as follows:

                   For Non Contracted Products
                   "Cost" is defined as the manufacturer's published wholesale
                   acquisition cost on the date of JDC's invoice to Tel-Drug,
                   plus additional adjustments to reflect normal and customary
                   quantity discounts and special promotional allowances,
                   excluding manufacturer's cash discounts.

                   For Contract Products
                   "Cost" is defined as the cost negotiated between the
                   manufacturer and Tel-Drug; provided that JDC shall have an
                   arrangement with the manufacturer regarding such contract
                   cost satisfactory to JDC. The JDC system pricing logic is
                   defined as best price. If a special promotional price is more
                   favorable than the contract price, the product will be priced
                   at the lower amount.

                   All orders must be electronically transmitted to qualify for
                   above pricing. Non-transmitted orders subject to cost plus.
                   [*] (excluding schedule II's, back orders and
                   emergency orders).


                   Additional Volume Discounts
                   JDC will allow additional credits in the form of volume
                   discount percentages to Tel-Drug monthly based on Tel-Drug's
                   monthly net purchase volume with JDC. Such credit for
                   additional volume shall be in the form of a check, payable to
                   Tel-Drug (the "Payment") which shall be delivered to Tel-Drug
                   by the tenth (10th) working day of each month. The amount of
                   the payment to Tel-Drug will be based on the schedule below:

</TABLE>

FISCAL YEAR ENDED JUNE 30, 1999, COMPARED WITH THE FISCAL YEAR ENDED JUNE 30,
1998

NET SALES. Net sales increased $202.9 million, or 33.1%, for the fiscal year
ended June 30, 1999, compared with the fiscal year ended June 30, 1998.
Institutional sales increased by $37.3 million, or 20.7% compared with fiscal
1998, due to increased sales to one prescription benefit management company
(PBM) and sales to another PBM that became a customer as a result of the
Company's acquisition of a drug wholesaler in June 1999. Chain store sales
increased by $82.5 million, or 62.9%, from higher sales to existing and new
chain store customers resulting from a focused marketing effort on this trade
class. Independent pharmacy sales increased by $81.9 million, or 27.3% from
higher sales to existing customers and new customers, including those obtained
in the June 1999 acquisition. The remaining $1.2 million sales increase was
primarily from software sales by Tykon, Inc. acquired in September 1998. In
addition, during fiscal 1999, the Company made $189.0 million in "dock-to-dock"
sales, which are not included in net sales due to the Company's accounting
policy of recording only the commission on such transactions as a reduction of
cost of goods sold. There were $62.1 million of dock-to-dock sales in fiscal
1998. Dock-to-dock sales represent bulk sales of pharmaceuticals to
self-warehousing retail chains for which the Company acts only as an
intermediary in the order and subsequent delivery of products to the customers'
warehouses. The commission on dock-to-dock sales is typically lower than the
gross profit realized on sales of products from inventory.

GROSS PROFIT. Gross profit increased 38.6%, to $41.1 million in fiscal 1999
compared with fiscal 1998 driven primarily by higher sales and partially by
improved margins. As a percentage of net sales, gross margin increased from
4.84% to 5.04% in fiscal 1999 compared with fiscal 1998. The increase in gross
margin percentage was mainly due to a shift in customer mix to higher margin
business, higher sales of more profitable generic pharmaceutical products and
sales of inventory acquired through advantageous purchasing. These benefits were
partially offset by higher sales to large customers which typically generate
lower margins.

OPERATING EXPENSES. Total operating expenses increased $5.8 million, or 27.8%,
to $26.7 million in fiscal 1999, compared with fiscal 1998. As a percentage of
net sales, total operating expenses decreased from 3.42% to 3.27% in fiscal 1999
compared with fiscal 1998. The increase in operating expenses in fiscal 1999
resulted primarily from incremental warehouse and distribution costs associated
with increased sales activity and higher personnel costs related to additional
managerial positions in several major functional areas of the Company. The
decrease in operating expense percentage for the year is due mainly to the
increase in chain store sales which typically generate a lower expense to sales
ratio than other trade classes.

NET INTEREST EXPENSE. Net interest expense increased $0.8 million, or 21.8%, in
fiscal 1999, compared with fiscal 1998. As a percentage of net sales, net
interest expense decreased from 0.61% to 0.57% in fiscal 1999 compared with
fiscal 1998. The increase in net interest expense was primarily the result of
higher average outstanding borrowings in support of the Company's growth,
partially offset by lower weighted average interest rates. Weighted average
interest rates decreased 91 basis points to 6.26% for the year primarily due to
the accounts receivable securitization facility finalized in August 1998.

OTHER INCOME, NET. Other income, net decreased from $530,000 to $431,000 in
fiscal 1999 compared with fiscal 1998. The decrease was primarily due to lower
recorded earnings from the Company's equity interest in the net income of PBI
during fiscal 1999, which totaled $332,000, compared with $389,000 in fiscal
1998.
         The Company's effective income tax rates of 37.7% in fiscal 1999 and
39.5% in fiscal 1998 differed from the statutory blended federal and state
effective rates primarily due to the impact of the amortization of intangible
assets that were not deductible for income tax purposes, partially offset by the
Company's equity in the net income of PBI, a portion of which was excludable
from taxable income.
         The effect of price inflation, as measured by the excess of LIFO costs
over FIFO costs, was $0.4 million in fiscal 1999 and $1.0 million in fiscal
1998. The decrease in the LIFO provision was due to changes in the Company's
inventory mix to include higher levels of generic pharmaceuticals and
modifications made in investment buying practices.

FISCAL YEAR ENDED JUNE 30, 1998, COMPARED WITH THE FISCAL YEAR ENDED MARCH 28,
1997

NET SALES. Net sales increased $132.9 million, or 27.7%, for the fiscal year
ended June 30, 1998, compared with the fiscal year ended March 28, 1997. Sales
to healthcare institutions increased by $55.2 million, or 44.3%, compared with
fiscal 1997, due to increased sales to a PBM added as a customer in August 1996
coupled with higher sales to new and existing hospital, clinic and nursing home
accounts. Independent pharmacy sales increased by $77.8 million, or 34.8%,
compared with fiscal 1997, from higher sales to existing and new retail
accounts, including $53.6 million to an association of retail pharmacies added
as a customer in May 1997 and $6.2 million to independent pharmacies that became
customers as a result of the Company's acquisition of a drug wholesaler in
October 1997. The Company experienced a net decrease in retail chain sales of
$0.1 million, compared to fiscal 1997, primarily due to the termination of the
Company's relationship with a large regional retail chain customer on September
30, 1997, (a decrease of approximately $68.5 million) partially offset by
increased sales to other existing and new retail chain customers of
approximately $68.4 million. In addition, during 1998, the Company made $62.1
million in dock-to-dock sales. There were no dock-to-dock sales in fiscal 1997.

GROSS PROFIT. Gross profit increased 37.1%, to $29.7 million in fiscal 1998
compared with fiscal 1997. As a percentage of net sales, gross margin increased
from 4.51% to 4.84% in fiscal 1998 compared with fiscal 1997. The increase in
gross margin percentage was due mainly to a shift in customer mix to higher
margin business, higher sales of more profitable generic pharmaceutical products
and sales of inventory acquired through advantageous purchasing.

OPERATING EXPENSES. Total operating expenses increased $3.7 million, or 21.5%,
to $20.9 million in fiscal 1998, compared with fiscal 1997. As a percentage of
net sales, total operating expenses decreased from 3.58% to 3.42% in fiscal 1998
compared with fiscal 1997. The increase in operating expenses in fiscal 1998
resulted primarily from incremental warehouse and distribution costs associated
with increased sales activity, higher personnel and occupancy costs related to
additional managerial positions in several major functional areas of the
Company, and legal fees associated with the conclusion of the Company's
relationship with its previously largest customer.

NET INTEREST EXPENSE. Net interest expense increased $184,000, or 5.1%, in
fiscal 1998, compared with fiscal 1997. As a percentage of net sales, net
interest expense decreased from 0.76% to 0.61% in fiscal 1998 compared with
fiscal 1997. The increase in net interest expense was primarily the result of
higher average outstanding borrowings offset by lower interest rates on the
Company's line of credit. In addition, the collection of approximately $9.5
million of accounts receivable on September 30, 1997, from the Company's then
largest customer, a relationship that was terminated in September 1997, reduced
the Company's working capital requirements and its borrowings.

OTHER INCOME, NET. Other income, net increased from $455,000 to $530,000 in
fiscal 1998 compared with fiscal 1997. The increase was primarily due to gains
on sales of investments partially offset by lower recorded earnings from the
Company's equity interest in the net income of PBI during fiscal 1998, which
totaled $389,000, compared with $410,000 in fiscal 1997.
         The Company's effective income tax rates of 39.5% in fiscal 1998 and
42.2% in fiscal 1997 differed from the statutory blended federal and state
effective rates primarily due to the impact of the amortization of intangible
assets that were not deductible for income tax purposes, partially offset by the
Company's equity in the net income of PBI, a portion of which was excludable
from taxable income.
         The effect of price inflation, as measured by the excess of LIFO costs
over FIFO costs, was $1.0 million in fiscal 1998 and $1.2 million in fiscal
1997. The decrease in the LIFO provision was due to changes in the Company's
inventory mix to include higher levels of generic pharmaceuticals and
modifications made in investment buying practices.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's working capital requirements are generally met through a
combination of internally generated funds, borrowings under the revolving line
of credit, the accounts receivable securitization facility, and trade credit
from its suppliers. The following ratios are used by the Company as key
indicators of its liquidity and working capital management:

<TABLE>

                                    June 30, 1999           June 30, 1998

<S>                                   <C>                     <C>
    Working capital (000s)             $20,068                 $52,528
    Current ratio                     1.13 to 1               1.56 to 1

</TABLE>

The $32.5 million decrease in working capital at June 30, 1999 was due primarily
to the sale of accounts receivable under the securitization facility discussed
below. Adjusted for the securitization, working capital and the current ratio
would have been $57.1 million and 1.37, respectively.
         The Company invested $879,000 in capital assets in fiscal 1999 and
$863,000 in fiscal 1998. The Company believes that continued investment in
capital assets is necessary to achieve its goal of improving operating
efficiency and information services capabilities, thereby improving its
productivity and ratio of operating expenses to net sales.
         In December 1996, the Company obtained a $1.5 million equipment loan
from a bank through the Missouri First Link program ("Missouri First") to
finance certain capital expenditures at its leased Cape Girardeau, Missouri,
facility. During the first year of the four-year agreement, the Missouri First
loan required monthly interest payments. In December 1997, the Company made a
$182,500 principal payment to Missouri First, in December 1998 a $437,500
principal payment was made and on March 31, 1999, the remaining $875,000 in
principal was paid.
          In November 1997, the Company's revolving line of credit was amended
to increase the maximum borrowings from $60 million to $75 million, including a
$5 million supplemental facility that expired August 3, 1998. Interest on
borrowings under the line of credit was reduced in April 1998 to daily LIBOR
plus 1.25%. In August 1998, the revolving line of credit was amended to be
secured solely by eligible inventories, to increase the facility to $75 million
and to extend its maturity through August 2001. Borrowings under the line of
credit were limited to 60% of eligible inventories. On June 1, 1999, in
conjunction with the acquisition of the wholesale drug distribution company
discussed below, the facility was increased to $95 million, the interest rate
was increased to LIBOR plus 1.75% and borrowing limits were increased to 65% of
eligible inventories. At June 30, 1999 and June 30, 1998, the unused portions of
the line of credit were $55.5 million and $14.8 million, respectively.

         In August 1998, the Company finalized a $45 million accounts receivable
purchase facility under an asset securitization structure with its primary
lender. The securitization carries an initial term of three years, with annual
renewal options, and bears interest at the 30-day LIBOR rate plus program and
liquidity fees of 0.71% payable monthly. Under the securitization, the Company's
accounts receivable are being sold on a non-recourse basis to a
bankruptcy-remote subsidiary of the Company as security for commercial paper
issued by an affiliate of the lender. Based on the structure of the arrangement,
the subsidiary's assets and liabilities, consisting of accounts receivable and
long-term debt, are no longer consolidated with those of the Company. In
December 1998, the facility was increased to $60 million. At June 30, 1999, $35
million of the facility was utilized. The Company believes that funds available
under the line of credit and the securitization facility, together with
internally generated funds, will be sufficient to meet its capital requirements
for the foreseeable future.
         On June 1, 1999, the Company consummated the acquisition of 100% of the
outstanding stock of Jewett Drug Co. ("Jewett"). Jewett is a pharmaceutical
distribution company based in Aberdeen, South Dakota, which provides
comprehensive pharmaceutical distribution services to over 250 customers in the
Upper Midwest and Great Plains region. The aggregate purchase price for this
acquisition of $34.3 million consisted of $21.5 million in cash and $12.8
million (555,556 shares) of the Company's common stock. Funds for the cash
portion of the purchase price were provided by the Company's revolving loan
facility. The acquisition was accounted for as a purchase. As such, Jewett
results are included in consolidated operating results from the acquisition
date. The acquisition resulted in goodwill of $30.5 million, which is being
amortized over 25 years.
         In September 1998, the Company acquired 100% of the stock of Tykon,
Inc., a wholesale distribution software developer, for cash consideration of
$2.0 million. During fiscal 1998, the Company made two acquisitions of
pharmaceutical distribution companies for aggregate consideration of $2.6
million, including cash payments and the issuance of notes payable.
         The increase in Stockholders' Equity from $16.0 million at June 30,
1998 to $35.9 million at June 30, 1999 is related primarily to the shares issued
in the Jewett acquisition and earnings for the year.

YEAR 2000

         Certain aspects of the Company's business (including that of its
subsidiaries) could be affected by what has commonly become known as the Year
2000 or Y2K problem. Specifically, the problem derives from computer software,
hardware and embedded chips that recognize, receive, process and store date data
using only two-digit years, and therefore, may malfunction when they encounter
dates which are from the 21st century, rather than the 1900's. Computerized
systems are fundamental to several key functions of the Company and its
subsidiaries. The following discussion includes the Company and its
subsidiaries. The Company operates its business using a network of distributed
AS/400, local area network (LAN) and PC Systems. The Company's financial,
distribution and operational systems reside on the AS/400. LANs are used
primarily for file sharing. PCs are used primarily as terminals to the AS/400
systems, with the exception of financial reporting and banking functions.
Several of the Company's warehouse operations are automated using radio
frequency (RF) equipment. The Company receives customer orders electronically,
either from PCs, data files or hand held devices. The Company also provides
software to pharmacies and drug distributors to help them automate functions
within their businesses.
         The Company began its Year 2000 efforts in the summer of 1997 and has
worked since then to identify and remediate potential Y2K issues. The Company's
Y2K project is being executed in phases, beginning with assessment, followed by
prioritization, remediation, testing, implementation and contingency planning.
Assessment, prioritization and remediation work on all known Y2K issues is
complete. Testing is complete for LAN, PC and AS/400 systems, which includes
financial, operational, banking and financial reporting systems. Testing has
indicated that LAN and PC systems are Year 2000 compliant and the Company is not
aware, at this point, of any further work required with these systems. The
remaining AS/400, RF and hand held ordering systems, which support distribution
and internal operations functions, have undergone rigorous testing procedures
before being implemented in production in all of the Company's locations. The
Company's software products have been remediated and tested and the results have
been positive, leading the Company to believe that these products are, in all
material respects, Y2K compliant. The Company is in the process of completing
its Y2K software implementation in customer sites, which it expects to complete
in October 1999. Software upgrades to enable the Company's software products to
handle Year 2000 date processing are being provided to customers free of charge
through electronic transmissions of the upgrade to customer computers. Customers
who use the Company's Resource software product to place electronic orders and
the Company's Scriptmaster software product to fill prescriptions are being
notified regarding potential hardware issues and given alternatives to resolve
the issue. The Company expects this effort to be completed in October 1999.




                                       4

         The Company does not sell non-IT embedded systems, but does use non-IT
embedded systems in the normal course of its business in areas such as alarm
systems, time clocks, etc. As does virtually every other company, the Company
does rely on third parties in the conduct of its business. The Company has
surveyed suppliers, customers, transportation companies, alarm system providers,
utilities, banks and other third parties it does business with, or who provide
products or services the Company uses containing non-IT embedded systems, on a
regular basis in an effort to determine their Y2K state of readiness. At the
present time, it appears that the majority of third parties with whom the
Company does business are reasonably certain they will be able to conduct
business without significant interruption at the century date change.
         The Company has essentially completed its Y2K contingency plan. The
Company's contingency planning efforts are focused on identifying the entities
that are critical to the Company's business functions, determining which
entities have the largest potential for impact if there are Y2K issues,
determining the likelihood of the potential problem, ranking the entities by
criticality and likelihood of potential problems, and developing work-around
plans to handle any potential emergency situation. The Company expects to
monitor critical situations from this point forward, revising contingency plans
as necessary.
         The costs of the Company's Y2K project have been incurred in the areas
of IT systems and contingency planning. The Company had spent approximately
$575,000 as of June 30, 1999 on its Year 2000 project and expects to spend an
additional $125,000 by October 1999, all from internally generated funds.
         The Company believes the greatest potential risks in connection with
the Year 2000 issue would be the inability of its suppliers to provide product
in a timely manner, the inability to obtain payments from its customers and the
inability of transportation companies to deliver product to its customers, any
of which could have a material adverse impact on the Company's operations,
liquidity and financial condition. Also, the issue of customer stockpiling in
anticipation of the Year 2000 poses a dilemma which potentially could have an
impact on the Company and other distributors of pharmaceuticals. Many industry
commentators have noted the likelihood that some patients, fearing Y2K
disasters, will attempt to stockpile prescriptions, thus causing supply chain
problems for manufacturers, distributors and retailers. This eventuality could,
of course, directly affect the Company's operations, liquidity or financial
condition. The Company's contingency plans are designed with the goal of
minimizing the potential impact caused by any Year 2000 problems of its
suppliers and other third parties. Therefore, the Company does not now believe
that any external Y2K problems will have a material adverse impact on its
operations, liquidity or financial condition.
         While the Company believes it has taken a comprehensive and reasonable
approach towards anticipating and addressing the potential impact of the century
date change on its business, there can be no assurance that the Company
internally, or any third party upon which the Company depends, will successfully
avoid all Y2K malfunctions.
         As part of the foregoing Y2K discussion, the Company has used a
significant number of forward looking statements (e.g., "expects," "believes,"
and similar phrases). These are based on the Company's present knowledge and
informed expectations that may change in the future based on new developments,
facts and circumstances.

EFFECT OF NEW ACCOUNTING STANDARDS

         The provisions of SFAS No. 130, "Reporting Comprehensive Income,"
became effective in fiscal 1999. The statement requires that an enterprise
report, by major component and as a single total, the change in its net assets
during the period from nonowner sources. The Company had no such items during
the periods covered by this analysis. The Company adopted the provisions of SFAS
No. 131, "Disclosures about Segments of an Enterprise and Related Information,"
during the fourth quarter of fiscal 1999. After application of the aggregation
criteria in SFAS No. 131, the Company operates in three segments. Only one,
Wholesale drug distribution, met the standards for separate disclosure. See Note
16 of Notes to Consolidated Financial Statements for the required disclosures.
The adoption by the Company during fiscal 1999 of SFAS No. 132, "Employers'
Disclosures and Pensions and Other Postretirement Benefits," did not impact the
Company's consolidated financial position, results of operations, cash flows or
disclosures. In June 1998, the Financial Accounting Standards Board issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities," which
is required to be adopted in years beginning after June 15, 1999 (subsequently
changed to June 15, 2000 by SFAS No. 137). The effect of this statement is not
expected to have a significant impact on the consolidated financial position or
results of operations of the Company.

                D&K HEALTHCARE RESOURCES, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements include the accounts of all divisions and
wholly owned subsidiaries of D&K Healthcare Resources, Inc. (the "Company"). All
significant intercompany accounts and transactions are eliminated.

Change in Fiscal Year

On June 30, 1997, the Company changed from a fiscal year ending the Friday
closest to March 31 in each year to a fiscal year ended June 30 of each year.
Therefore, fiscal 1999 and 1998 ended on June 30. Fiscal 1997 ended on March 28,
1997 and included 52 weeks. The three-month period began March 29, 1997 and
ended June 30, 1997. References to years relate to fiscal years rather than
calendar years unless otherwise stated.

Name Change to D&K Healthcare Resources, Inc.

In 1998, through an amendment to its Certificate of Incorporation and with the
approval of its stockholders, the Company changed its corporate name from D&K
Wholesale Drug, Inc., to D&K Healthcare Resources, Inc.

Concentration of Credit Risk

The Company is a full-service, regional wholesale drug distributor. From
facilities in Missouri, Kentucky, Minnesota, and South Dakota, the Company
distributes a broad range of pharmaceutical products, health and beauty aids and
related products to its customers in more than 24 states. The Company focuses
primarily on a target market sector that includes independent retail,
institutional, franchise, chain store, and alternate site pharmacies in the
Midwest and South.

The Company had a single customer that accounted for approximately 18% and 20%,
respectively, of net sales for the three months ended June 30, 1997 and in 1997.
The supply agreement with this customer was terminated on September 30, 1997,
upon the acquisition of the customer by a third party. Upon termination of the
supply agreement, the Company collected the entire amount of its accounts
receivable due from this customer. In 1999 and 1998, sales to a single customer
represented approximately 12% and 13% of total net sales, respectively.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Restricted Cash

Restricted cash of $0.7 million and $4.0 million at June 30, 1999, and June 30,
1998, respectively, represents cash receipts from customers that must be used to
reduce borrowings under the revolving line of credit and are included in cash.

Revenue Recognition

Revenue is recognized when products are shipped or services are provided to
customers. During 1999 and 1998, the Company had $189.0 million and $62.1
million, respectively, of "dock-to-dock" sales, which are excluded from net
sales due to the Company's policy of recording only the commission on such
transactions as a reduction against cost of goods sold in the consolidated
statements of operations. Dock-to-dock sales represent large volume sales of
pharmaceuticals to major self-warehousing retail chain pharmacies whereby the
Company acts as an intermediary in the order and subsequent delivery of products
to the customers' warehouses. The Company had no dock-to-dock sales during the
three-month period ended June 30, 1997 or in 1997.

Inventories

Inventories consist of pharmaceutical drugs and related over-the-counter items
that are stated at the lower of cost or market. Cost is primarily determined
using the last-in, first-out (LIFO) method.




                                       6

<PAGE>   13







Property and Equipment

Property and equipment is stated at cost. Depreciation and amortization are
charged to operations primarily using the straight-line method over the shorter
of the estimated useful lives of the various classes of assets, which vary from
two to 30 years, or the lease term for leasehold improvements. For income tax
purposes, accelerated depreciation methods are used.

Intangible Assets

Intangible assets are stated at cost less accumulated amortization. Amortization
is determined using the straight-line method over the estimated useful lives of
the related assets.

Long-Lived Assets

If facts and circumstances suggest that a long-lived asset may be impaired, the
carrying value is reviewed. If this review indicates that the carrying value of
the asset will not be recovered, as determined by a review of projected
undiscounted cash flows related to the asset over its remaining life, the
carrying value of the asset is reduced to its estimated fair value.

Income Taxes

Deferred tax assets and liabilities are recognized for estimated future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective bases
for income tax purposes. Deferred tax assets and liabilities are measured and
recorded at tax rates in effect for the year in which those temporary
differences are expected to be recovered or settled.

Book Overdrafts

Accounts payable includes book overdrafts (outstanding checks) of $5.2 million
and $14.1 million at June 30, 1999, and June 30, 1998, respectively.

Treasury Stock

In May 1999, the board of directors authorized the repurchase of up to 300,000
shares of the Company's outstanding common stock. The shares may be acquired in
the open market or in private transactions over a twelve month period from the
date of authorization.

Earnings per Share

Statement of Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS
No. 128) requires a dual presentation of basic and diluted earnings per share.
Basic earnings per share excludes dilution and is computed by dividing net
income (loss) by the weighted average number of common shares outstanding for
the period. Diluted earnings per share reflects the potential dilution that
would occur if securities or other contracts to issue common stock were
exercised or converted into common stock. All share and per share amounts have
been stated in accordance with the provisions of SFAS No. 128 (see Note 14).

Reclassifications

Certain reclassifications have been made to the prior years' financial
statements to conform to the current year presentation.


NOTE 2.  ACQUISITIONS

On June 1, 1999, the Company consummated the acquisition of 100% of the
outstanding stock of Jewett Drug Co. ("Jewett"). Jewett is a pharmaceutical
distribution company based in Aberdeen, South Dakota, that provides
comprehensive pharmaceutical distribution services to over 250 customers in the
Upper Midwest and Great Plains region. The aggregate purchase price for this
acquisition of $34.3 million consisted of $21.5 million in cash and $12.8
million (555,556 shares) of the Company's common stock. Funds for the cash
portion of the purchase price were provided by the Company's revolving loan
facility. In connection with the transaction, the Company paid investment
banking fees of $0.8 million to a firm that employs a member of the Company's
Board of Directors.








                                       7


<PAGE>   14



Also, on June 1, 1999, the Company entered into an amendment to the Amended and
Restated Loan and Security Agreement with Fleet Capital Corporation pursuant to
which the Company's revolving loan facility was increased from $75 million to
$95 million and Jewett became a party to, and permitted borrower under, that
facility (See Note 8).

The acquisition was accounted for as a purchase. As such, Jewett results are
included in consolidated operating results from the acquisition date. The
acquisition resulted in goodwill of $30.5 million which is being amortized over
25 years.

The following unaudited pro forma information presents a summary of consolidated
results of operations of the Company and Jewett for 1999 and 1998 as if the
acquisition had occurred at July 1, 1998, and July 1, 1997, respectively, with
pro forma adjustments to give effect to amortization of goodwill, interest
expense on acquisition debt and certain other adjustments, together with related
income tax effects. The unaudited pro forma information has been prepared for
comparative purposes only and does not purport to be indicative of the results
of operations had these transactions been completed as of the assumed dates or
which may be obtained in the future (in thousands, except per share amounts).

In September 1998, the Company acquired 100% of the stock of Tykon, Inc., a
wholesale distribution software developer, for cash consideration of $2.0
million. During fiscal 1998, the Company made two acquisitions of pharmaceutical
distribution companies for aggregate consideration of $2.6 million, including
cash payments and the issuance of notes payable.

NOTE 3.  INVENTORIES

Substantially all inventories are stated at the lower of LIFO cost or market. If
the Company had used the first-in, first-out (FIFO) method of inventory
valuation, which approximates current replacement cost, inventories would have
been $8.5 million and $8.0 million higher than reported at June 30, 1999, and
June 30, 1998, respectively.

NOTE 5.  INVESTMENT IN PBI

The Company owns approximately 50% of the capital stock of Pharmaceutical
Buyers, Inc. ("PBI"), a Colorado-based group purchasing organization. The
Company acquired approximately 50% of the voting and non-voting common stock of
PBI for $3.75 million in cash. The Company's investment in PBI is accounted for
under the equity method.

The Company's equity in the net income of PBI totaled $332,000, $389,000,
$410,000 and $51,000, respectively, for 1999, 1998, 1997 and for the three
months ended June 30, 1997, which is net of amortization of goodwill associated
with its investment in PBI of $276,000, $276,000, $276,000 and $69,000 for these
respective fiscal periods. The PBI goodwill is being amortized using the
straight line method over a period of 25 years. During 1999, 1998, and 1997, the
Company received cash dividends of $350,000, $350,000, and $300,000,
respectively, from PBI, which were recorded as a reduction in the carrying
amount of the investment.

Summarized balance sheet information for PBI for its fiscal year ended December
31, 1998, and unaudited information for the periods ended June 30, 1999 and 1998
included current assets of $2.9 million, $3.0 million and $2.3 million,
noncurrent assets of $0.6 million, $0.5 million and $0.8 million, current
liabilities of $1.7 million, $1.9 million and $1.0 million and noncurrent
liabilities of $5.2 million, $5.1 million, and $6.3 million, respectively.
Summarized income statement information for PBI for its fiscal year ended
December 31, 1998, and unaudited information for the six months ended June 30,
1999 and June 30, 1998, and for the three months ended June 30, 1997, included
net revenues of $5.6 million, $2.7 million, $2.8 million and $1.3 million and
income from continuing operations and net income of $1.4 million, $0.6 million,
$0.6 million and $0.3 million, respectively.

Certain other shareholders of PBI have the option to exchange their combined 20%
ownership interests in PBI for shares of the Company's common stock under the
terms of the original purchase agreement. Those options have been determined to
be dilutive in 1999 and are included in the reconciliation of the basic and the
diluted earnings per share computation (See Note 14).

NOTE 6.  OTHER ASSETS

Other assets include deferred debt issuance costs of $0.9 million and $0.3
million at June 30, 1999 and 1998, respectively, that are being amortized over
the periods the related debt is outstanding. Accumulated amortization amounted
to $0.4 million and $0.2 million at June 30, 1999 and 1998, respectively.
Amortization of deferred debt issuance costs totaled $188,000 in 1999, $59,000
in 1998, $73,000 in 1997 and $20,000 for the three-month period ended June 30,
1997, and is included in interest expense in the consolidated statements of
operations.

The excess of purchase price over the fair value of net assets acquired is being
amortized using the straight-line method over periods of 10 to 40 years.
Amortization of intangible assets totaled $0.6 million in 1999, $0.4 million in
1998, $0.4 million in 1997 and $0.1 million for the three-month period ended
June 30, 1997.

During 1998, the excess of purchase price over the fair value of net assets
acquired was reduced by $4.1 million to reflect the reversal of the deferred tax
asset valuation allowance related to acquired net operating loss, alternative
minimum tax and charitable contribution carryforwards (see Note 12).

</TABLE>


As of June 30, 1999, the revolving line of credit had a maximum borrowing
capacity of $95 million, expiring August 7, 2001. Prior to June 1, 1999, the
revolving line of credit had maximum borrowing capacity of $75 million. Under
the loan agreement, the total amount of loans and letters of credit outstanding
at any time may not exceed the lesser of an amount based on percentages of
eligible inventories (the borrowing base formula), or $95 million. Generally,
advances bear interest at the London Interbank Offered Rate (LIBOR) plus 1.75%
or at the prime rate (7.75% at June 30, 1999) plus 0.25% per annum payable
monthly. At June 30, 1999 and June 30, 1998, the Company's borrowings under the
revolving line of credit bore interest at a weighted average LIBOR-based rate of
6.96% and 6.94%, respectively. The Company was required to pay annual facility
fees of $201,000 and $289,000, respectively, in 1999 and 1998. At June 30, 1999
and June 30, 1998, the borrowing base formula amounted to $106.8 million and
$92.6 million, respectively. At June 30, 1999 and June 30, 1998, the unused
portion of the line of credit amounted to $55.5 million and $14.8 million,
respectively. The agreement expires August 7, 2001, and, therefore, the related
debt has been classified as long-term. The revolving line of credit is secured
by eligible inventories.

The Company also has an interest rate collar agreement, whereby the LIBOR on
$10.0 million of the outstanding revolving line of credit balance shall not
exceed 6.75%. If the LIBOR is less than 5.25%, then the LIBOR rate on $7.5
million of the outstanding revolving line of credit balance shall not be less
than 5.25%. On March 31, 1999, the Company executed an additional interest rate
collar agreement on $40.0 million of the outstanding revolving line of credit,
whereby the LIBOR shall not exceed 6.85% nor be less than 4.93%.

In the first quarter of fiscal 1999, the Company entered into a $45 million
accounts receivable purchase facility under an asset securitization structure
("the Securitization") with its primary lender. In the second quarter of fiscal
1999, the Securitization was increased to a $60.0 million facility. The
Securitization has an initial term of three years, with annual renewal options,
and bears interest at the LIBOR rate (5.21% at June 30, 1999) plus program and
liquidity fees of 0.71% paid monthly. The Company was required to pay a
structuring fee of $225,000, which is being amortized over the initial term of
the arrangement. Under the Securitization, accounts receivable are sold on a
non-recourse basis to a bankruptcy-remote subsidiary of the Company as security
for commercial paper issued by an affiliate of the lender. Based upon the
structure of the arrangement, the subsidiary's assets and liabilities,
consisting of accounts receivable and long-term debt, are not consolidated with
those of the Company. Accordingly, the Company's trade accounts receivable and
long-term debt at June 30, 1999 are net of $35 million, which represent accounts
receivable that were sold under the Securitization.

The revolving accounts receivable credit facility had a maximum borrowing
capacity of $10 million at June 30, 1998. Under the facility, the total amount
of loans outstanding could not exceed the lesser of eligible accounts receivable
or $10 million. Advances bore interest at the prime rate (8.5% at June 30, 1998)
plus 2.0%. At June 30, 1998, the unused portion of the facility amounted to $4.9
million. The facility expired August 31, 1998, and the entire remaining
principal was paid in full on August 31, 1998.

The Missouri First Link loan ("Missouri First") was used to finance and was
secured by certain capital expenditures at a leased distribution facility. The
Missouri First loan bore interest at a fixed rate of 70% of the bank's prime
rate (8.5% at June 30, 1998) plus 0.50%, or 6.45%. A $437,500 principal
reduction was required in December 1998; after such time, the loan required
monthly payments of $36,458 plus interest until maturity in December 2000. In
March 1999, the remaining principal of the Missouri First loan was paid in full.


                                       10

<PAGE>   17
Subordinated notes payable to an insurance company bore interest at 11% payable
semiannually, and consisted of nonconvertible notes of $1.1 million and
convertible notes of $1.75 million. Principal on the nonconvertible notes was
paid in full in December 1997, and the convertible notes payable were converted
into 530,978 shares of the Company's common stock. In June 1998, a $1.0 million
convertible note payable was converted into 59,880 shares of the Company's
common stock. The debt conversions were recorded as a component of stockholders'
equity in the June 30, 1998, consolidated balance sheets.

The Company is required under the terms of its debt agreements to comply with
certain financial covenants, including those related to the maintenance of
current ratio, tangible net worth and debt service and interest coverage ratios.
The Company is also limited in its ability to make loans and investments, to
enter into leases, to make capital expenditures and/or to incur additional debt,
among other things, without the consent of its lenders.

At June 30, 1999, maturities of long-term debt, including capital lease
obligations, were as follows (in thousands):

NOTE 9.  COMMITMENTS AND CONTINGENCIES

The Company leases office and warehouse space and other equipment through
noncancelable operating leases. Rental expense under operating leases was $0.9
million, $0.9 million, $0.7 million and $0.2 million in 1999, 1998, 1997 and for
the three-month period ended June 30, 1997, respectively. Minimum rental
payments under these leases with initial or remaining terms of one year or more
at June 30, 1999, are $10.2 million and payments during the succeeding five
years are: 2000, $1.9 million; 2001, $1.6 million; 2002, $1.5 million; 2003,
$1.4 million; 2004, $1.1 million; and thereafter, $2.7 million.

There are various pending claims and lawsuits arising out of the normal course
of the Company's business. In the opinion of management, the ultimate outcome of
these claims and lawsuits will not have a material adverse effect on the
financial position or results of operations of the Company.

NOTE 10.  STOCK OPTIONS

In 1992, the Company adopted a Long-Term Incentive Plan that authorized the
Compensation Committee of the Board of Directors ("the Committee") to grant key
employees and officers of the Company incentive or non-qualified stock options,
stock appreciation rights, performance shares, restricted shares and performance
units. Options to purchase up to 200,000 shares of common stock were authorized
under the Long-Term Incentive Plan. The Committee determines the price
(generally no less than fair market value on the date of grant) and terms at
which awards may be granted, along with the duration of the restriction periods
and performance targets. In 1998, the Company's shareholders approved an
amendment to the Plan to increase the number of shares available for grant to
500,000 shares. Stock options granted under the Long-Term Incentive Plan are not
exercisable earlier than six months from the date of grant (except in the case
of death or disability of the employee holding the same), nor later than 10
years from the date of grant. In January 1997, 67,999 non-qualified and
incentive stock options outstanding under the Company's Long-Term Incentive
Plan, with exercise prices ranging from $3.875 to $7.00 per share, were canceled
and replaced with an equivalent number of non-qualified and incentive options
with an exercise price equal to the then fair market price of the stock, $3.75
per share.

In 1993, the Board of Directors of the Company adopted the D&K Wholesale Drug,
Inc. 1993 Stock Option Plan ("the 1993 Plan") to grant key employees of the
Company non-qualified stock options to purchase up to 350,000 shares of the
Company's common stock. The 1993 Plan is administered by the Company's Board of
Directors, which determines the price and terms by which awards may be granted.
Stock options granted under the 1993 Plan are immediately exercisable from the
date of grant and expire not later than 10 years from the date of grant. The
exercise price of all options granted pursuant to the 1993 Plan was equal to the
fair market value of stock on the respective dates of grant. In January 1997,
60,000 non-qualified stock options outstanding under the 1993 Plan, with
exercise prices ranging from $3.875 to $7.00 per share, were canceled and
replaced with an equivalent number of non-qualified stock options with an
exercise price equal to the then fair market price of the stock, $3.75 per
share.

NOTE 11.  WARRANTS

The Company has outstanding warrants to purchase 22,072 shares of common stock
at a price of $0.005 per share. These warrants are exercisable only at such time
as a principal investor receives, following a merger or sale of all or
substantially all of the assets of the Company, in excess of a 30% compounded
annual rate of return on its investment in common stock of the Company. The
warrants were not exercisable at June 30, 1999, and will expire in December
1999. The Company does not believe the conditions for the exercise of the
warrants will be satisfied.

In June 1994, the Company entered into a letter agreement with an independent
research firm to produce reports with respect to the Company's publicly traded
equity securities. The term of the agreement was 13 months and in consideration
for the research reports, the Company granted the firm warrants to purchase up
to 70,000 shares of the Company's common stock at an exercise price equal to the
closing price of the stock on the date of the agreement, which was $4.125 per
share. The warrants were exercisable for a period of three years from the date
of the agreement. The research firm earned the warrants on a vesting schedule
over the 13-month term of its services. Fifty percent of the warrants vested on
the date of the agreement, an additional 25% vested upon issuance of a second
research report in November 1994, and the final 25% vested upon issuance of a
third research report in June 1995. The Company recorded total expense of
$70,000 related to these warrants. During the three-month period ended June 30,
1997, the Company agreed to extend the expiration of the warrants through June
1998 in exchange for additional research reports. The Company recorded expense
of $77,000 based upon the estimated fair value of the warrants, as amended,
during the three-month period ended June 30, 1997. In 1998, the research firm
exercised the warrants, resulting in the issuance of 70,000 shares of common
stock of the Company, recorded as additional equity of $288,750.

In connection with the acquisitions of two companies in fiscal 1995, net
deferred tax liabilities of $4.1 million were established for the differences in
the income tax basis of assets and liabilities acquired and their carrying
amounts for financial reporting purposes. In addition, deferred tax assets of
$4.0 million were recorded with respect to net operating loss carryforwards,
contribution carryforwards, and alternative minimum tax carryforwards that were
generated by the companies prior to their acquisitions. The use of
pre-acquisition operating losses is subject to limitations imposed by the
Internal Revenue Code and if not utilized by the Company, the net operating loss
carryforwards will expire beginning in 2007. At March 28, 1997, the Company
recorded a valuation allowance of $4.2 million primarily due to the uncertainty
of utilizing the pre-acquisition operating losses and other carryforwards.

During the three-month period ended June 30, 1997, the Company utilized $306,000
of the net operating loss carryforwards as a deduction against taxable income
for that period. Accordingly, the recorded valuation allowance and the excess of
purchase price over the fair value of net assets acquired were adjusted by
$122,000 to reflect the utilization at June 30, 1997.

In 1998, based upon its current and forecasted taxable earnings levels for
future years, the Company determined that it was more likely than not that the
remaining acquired net operating loss, contribution and alternative minimum tax
credit carryforwards would be utilized against consolidated taxable income in
the current and future years. Therefore, the remaining valuation allowance of
$4.1 million was released. This resulted in a corresponding increase to deferred
tax assets and a reduction in the excess of purchase price over the fair value
of net assets acquired. The Company utilized $3.2 million of the net operating
loss carryforwards in 1998. The annual net operating loss limitation for 1999
and future years is $1.0 million and begins to expire in 2007.

NOTE 13.  EMPLOYEE BENEFIT PLANS

The Company has a defined contribution 401(k) plan covering substantially all of
its employees. Plan participants may contribute up to 20% of their annual
compensation, subject to certain limitations. The Company contribution is
discretionary and is currently equivalent to 25% of employees' contributions up
to a maximum contribution based on 6% of eligible compensation. Expenses related
to the plan were $66,000 in 1999, $45,000 in 1998, $49,000 in 1997, and $20,000
for the three-month period ended June 30, 1997. Jewett has a defined
contribution 401(k) plan covering substantially all of its employees, which was
still in existence at June 30, 1999. Jewett also participates in the Central
States Pension, a multiemployer pension plan, on behalf of its union employees
in accordance with the union agreement.

The Company also has an executive retirement benefit plan, implemented in 1998,
that provides supplemental pre-retirement life insurance plus supplemental
retirement income to key executives. The life insurance benefit is calculated at
three times annual salary as of the date of participant enrollment. The
retirement income benefit is provided through discretionary contributions to
each participant's account, which vest 20% annually and are fully vested upon
attaining age 65. Upon retirement, the accumulated account balance is paid to
the participant over 15 years in quarterly benefit payments. The Company's
expense related to the plan was $245,000 in 1999 and $176,000 in 1998.

NOTE 15.  EFFECT OF NEW ACCOUNTING STANDARDS

The provisions of SFAS No. 130, "Reporting Comprehensive Income," became
effective in fiscal 1999. The statement requires that an enterprise report, by
major component and as a single total, the change in its net assets during the
period from nonowner sources. The Company had no such items during the periods
presented.

The Company adopted the provisions of SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information," during the fourth quarter of fiscal
year 1999. See Note 16 for the required disclosures.

The adoption by the Company during fiscal year 1999 of SFAS No. 132, "Employers'
Disclosures about Pensions and Other Postretirement Benefits," did not impact
the Company's consolidated financial position, results of operations, cash
flows, or disclosures.

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities," which is
required to be adopted in years beginning after June 15, 1999 (subsequently
changed to June 15, 2000 by SFAS No. 137). The effect of this statement is not
expected to have a significant impact on the consolidated financial position or
results of operations of the Company.

NOTE 16.  BUSINESS SEGMENTS

During the fourth quarter of fiscal 1999, the Company adopted SFAS No. 131. This
statement establishes standards for the way public companies report information
about operating segments that is consistent with that made available to the
management of the Company in allocating resources and assessing performance.

After application of the aggregation criteria, the Company has three
identifiable business segments, only one of which, Wholesale drug distribution,
meets the quantitative thresholds for separate disclosure prescribed in SFAS No.
131. This segment is described in Note 1. The Company's equity investment in PBI
(see Note 5) is a second segment. Two wholly owned software subsidiaries, Viking
Computer Services, Inc. and Tykon, Inc. constitute the third segment. Viking
markets a pharmacy management software system and Tykon developed and markets a
proprietary PC-based order entry/order confirmation system to the drug
distribution industry. These two segments are combined as Other in the table
below.

Though the Wholesale drug distribution segment operates from several different
facilities, the nature of its products and services, the types of customers and
the methods used to distribute its products are similar and thus they have been
aggregated for presentation purposes. The Company operates principally in the
United States. Intersegment sales have been recorded at amounts approximating
market. Interest and corporate expenses are allocated to wholly owned
subsidiaries only. Assets have been identified with the segment to which they
relate.
