NOTE 1 - BASIS OF PRESENTATION

         The Financial Statements presented herein and these notes are
unaudited. Certain information and footnote disclosures normally included in the
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to the rules and regulations
of the Securities and Exchange Commission ("SEC"). Although Black Box
Corporation (the "Company") believes that all adjustments necessary for a fair
presentation have been made, interim periods are not necessarily indicative of
the results of operations for a full year. As such, these financial statements
should be read in conjunction with the financial statements and notes thereto
included in the Company's most recent Form 10-K which was filed with the SEC for
the fiscal year ended March 31, 1999. Certain prior year amounts have been
reclassified to conform to the current year financial statement presentation.

NOTE 2 - INVENTORIES

         Inventories are stated at the lower of cost (first-in, first-out
method) or market. The net inventory balances are as follows:

                                   December 31,        March 31,

NOTE 3 - FINANCIAL DERIVATIVES

         The Company has entered and will continue in the future, on a selective
basis, to enter into forward exchange contracts to reduce the foreign currency
exposure related to certain intercompany transactions. On a monthly basis, the
open contracts are revalued to the current exchange rates and the resulting
gains and losses are recorded in other income. These gains and losses offset the
revaluation of the related foreign currency denominated receivables.

         At December 31, 1999, the open foreign exchange contracts were in Yen,
Euro, Sterling Pound and Canadian Dollars. These open contracts were valued at
approximately $4,406, with contract rates of 102.02 Yen per U.S. dollar, 1.0235
to 1.0245 Euro per U.S. dollar, 1.6237 to 1.6273 Sterling Pound per U.S. dollar
and 1.4791 to 1.4804 Canadian dollar per U.S. dollar, and will expire over the
next two months. The effect of these contracts on net income for the three and
nine month periods ended December 31, 1999 was not material.

                                   (UNAUDITED)
                (Dollars in thousands, except per-share amounts)


NOTE 4 - COMPREHENSIVE INCOME

         In the first quarter of Fiscal 1999, the Company adopted Statement of
Financial Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive
Income," which established standards for reporting and displaying comprehensive
income and its components in financial statements. Comprehensive income is
defined as net income and all nonowner changes in shareholders' equity.
Accumulated other comprehensive income consists entirely of foreign currency
translation adjustments. Total comprehensive income for the three and nine month
periods ended December 31, 1999 and three and nine month periods ended December
31, 1998 were $11,683, $34,107, $9,769 and $28,313, respectively.

NOTE 5 - EARNINGS PER SHARE

         Basic earnings per common share were computed based on the weighted
average number of common shares issued and outstanding during the relevant
periods. Diluted earnings per common share were computed under the treasury
stock method based on the weighted average number of common shares issued and
outstanding, plus additional shares assumed to be outstanding to reflect the
dilutive effect of common stock equivalents. The following table details this
calculation:

NOTE 6 - ADOPTION OF NEW ACCOUNTING STANDARDS

         In June 1998, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities,"

for derivative instruments and requires that an entity recognize all derivatives
as either assets or liabilities and measure those instruments at fair value. The
Company is currently evaluating the effects of SFAS No. 133 and does not
expect its adoption to have a material effect on the Company's financial
statements or results of operations.

NOTE 10 - SEGMENT REPORTING

         Since the annual report for the fiscal year ended March 31, 1999, the
Company has changed its basis of segmentation from a geographic basis to a
product and service line basis. The Company now manages the business primarily
on a product and service line basis. Its reportable segments are comprised of
On-Site Support and Phone Support. The Other operating segment includes
corporate expenses. Corporate expenses include costs related to tradename and
trademark protection and various administrative items. The Company reports its
segments separately because of differences in the ways the product and service
lines are managed and operated. Consistent with SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information," the Company aggregates
similar operating segments into reportable segments.

         The Company evaluates the performance of each segment based on
"Worldwide EBITA." A segment's Worldwide EBITA is its earnings before interest,
taxes and amortization with all profit on intercompany sales allocated to the
segment providing the third-party revenues. Intersegment sales are not reviewed
by management and are not included in the total revenues

for the benefit of the On-Site Support segment but are not allocated for
internal management reporting and are, therefore, not allocated herein. These
unallocated costs include certain order fulfillment, shipping and various
overhead items. Segment interest income, interest expense and expenditures for
segment assets are not presented to or reviewed by management, and therefore are
not presented.

         Revenues for the three and nine month periods ended December 31, 1999
were $127,128 and $342,537, respectively, an increase of $42,339, or 49.9%, and
$105,522, or 44.5%, respectively, over the same period in the prior year.
Revenues from on-site support for the three months ended December 31, 1999
(Third Quarter 2000) were $38,518, an increase of $32,745, or 567.2%, over
revenues for the three months ended December 31, 1998 (Third Quarter 1999). For
the nine months ended December 31, 1999, revenues from on-site support were
$86,226, an increase of $69,561, or 417.4%, over revenues for the nine months
ended December 31, 1998. On-site support revenue growth for the quarter and
year-to-date was primarily due to the Company's continued expansion by merger of
its on-site technical support capabilities as well as strong demand for on-site
services from customers of existing on-site service providers.

         Revenues from the Company's phone support business for Third Quarter
2000 were $88,610, an increase of $9,594, or 12.1%, over revenues for Third
Quarter 1999. For the nine months ended December 31, 1999, revenues from the
phone support business were $256,311, an increase of $35,961, or 16.3%, over
revenues for the nine months ended December 31, 1998. Overall, phone support
revenue growth was driven by strong sales in all geographic regions. Phone
support revenues from North America for Third Quarter 2000 were $44,862, an
increase of $5,998, or 15.4%, over revenues for Third Quarter 1999. For the nine
months ended December 31, 1999, phone support revenues from North America were
$137,677, an increase of $20,466, or 17.5%, over revenues for the nine months
ended December 31, 1998. The growth of North America phone support revenues is
driven primarily by continued strong demand for cables and connectors,
ServSwitch, racks and cabinets, power protection, and LAN products from
customers of all sizes. International phone support revenues for Third Quarter
2000 were $43,748, an increase of $3,596, or 9.0%, over revenues for the same
period in the prior year. For the nine months ended December 31, 1999,
International phone support revenues were $118,634, an increase of $15,495, or
15.0%, over revenues for the nine months ended December 31, 1998. International
phone support revenue growth for the quarter was driven by strong customer
demand for cables and connectors, ServSwitch, LAN products, power protection and
racks and cabinets while the nine month growth was driven primarily by strong
demand for cables and connectors, ServSwitch, modems and LAN products. If
exchange rates had remained constant from the corresponding periods in the prior
year, International phone support revenues for the three and nine month periods
ended December 31, 1999 would have increased 11.9% and 15.5%, respectively.

         Reported revenue dollar and percentage growth of the Company's largest
subsidiaries over the comparable periods in the prior year were as follows:
Japan revenues were $9,046, up $1,895, or 26.5%, in Third Quarter 2000 and were
$24,345, up $5,366, or 28.3%, year-to-date; United Kingdom revenues were $8,729,
up $297, or 3.5%, in Third Quarter 2000 and were $25,261, up $2,332, or 10.2%,
year-to-date; and France revenues were $6,379, up $93, or 1.5%, in Third Quarter
2000 and were $16,647, up $730, or 4.6%, year-to-date. Excluding Japan, United
Kingdom and France, the remaining international business grew $1,311, or 7.2%,
in Third Quarter 2000 and increased $7,067, or 15.6%, year-to-date. Japan
revenues increased, in part, due to the strengthening of the Japanese Yen
compared to the U.S. Dollar. If exchange rates had remained constant from the
corresponding periods in the prior year, Japan revenues would have increased
9.9%, for the three months ended December 31, 1999 and increased 9.6%, for the
nine months ended December 31, 1999; United Kingdom revenues would have
increased 6.5%, for the three months ended December 31, 1999 and increased
13.5%, for the nine months ended December 31, 1999; and France revenues would
have increased 15.3%, for the


                                       16
<PAGE>   17

three months ended December 31, 1999 and increased 13.2% for the nine months
ended December 31, 1999.

         Gross profit in Third Quarter 2000 increased to $55,397, or 43.6% of
revenues, from $42,073, or 49.6% of revenues, in Third Quarter 1999. Gross
profit for the nine month period ended December 31, 1999 increased to $152,147,
or 44.4% of revenues, from $116,854, or 49.3%, of revenues over the same period
in the prior year. The decline in gross profit margin for the quarter and the
nine months ended December 31, 1999 was due primarily to the increase in mix of
revenue from the Company's on-site support services which provides slightly
lower gross margins. Gross profit margins in the phone support business also
declined in the three month period ending December 31, 1999 compared to the
prior year primarily as a result of price reductions on non-Black Box labeled
products in North America. Phone support gross profit margins for the nine month
period ending December 31, 1999 were comparable to the same period in the prior
year. The revaluation of foreign denominated intercompany receivables had an
unfavorable impact on gross profit margin when compared to the prior year.
Excluding the impact of revaluing the intercompany receivables, the gross profit
margin was 43.8% for Third Quarter 2000 compared to 48.6% for Third Quarter 1999
and 44.5% for the nine months ended December 31, 1999 compared to 49.0% for the
nine months ended December 31, 1998.

         Selling, general and administrative ("SG&A") expenses in Third Quarter
2000 were $33,093, or 26.0% of revenues, an increase of $8,514 over SG&A
expenses of $24,579, or 29.0% of revenues, in Third Quarter 1999. SG&A expenses
for the nine month period ended December 31, 1999 were $89,651, or 26.2% of
revenues, an increase of $20,582 over SG&A expenses of $69,069, or 29.1% of
revenues over the same period in the prior year. SG&A expense as a percentage of
revenues decreased from last year primarily due to the increase in mix of
revenue from the Company's on-site support services which provides slightly less
operating expense relative to revenues. The dollar increases from the same
periods in the prior year related primarily to additional marketing and
personnel costs worldwide and additional support costs related to the addition
of the Company's on-site technical services product line.

         Operating income before amortization in Third Quarter 2000 was $22,304,
or 17.6% of revenues, compared to $17,494, or 20.6% of revenues, in Third
Quarter 1999. The decline in margin was due primarily to the increase in mix of
revenues from the Company's on-site support services which provides slightly
lower operating margins. Operating income before amortization for the nine month
period ended December 31, 1999 was $62,496, or 18.2% of revenues, compared to
$47,785, or 20.2% of revenues over the same period in the prior year. Intangible
amortization for the three and nine month periods ended December 31, 1999 were
$1,625, an increase of $470, or 40.7%, and $4,280, an increase of $1,189, or
38.5%, respectively. The increase in amortization is due to additional goodwill
related to the Company's continued expansion by merger of its on-site support
providers.

         Net interest expense for the three and nine month periods ended
December 31, 1999 was $1,012 and $1,686 respectively, an increase from the same
periods last year of $775 and $1,166, respectively, due to an increase in
borrowings for the repurchase of the Company's Common Stock and the continued
expansion by merger of its on-site support providers.

         The tax provision in Third Quarter 2000 was $7,557, or an effective tax
rate of 38.0%, compared to $6,405, or an effective tax rate of 40.0%, in Third
Quarter 1999. The tax provision for the


                                       17
<PAGE>   18

nine month period ended December 31, 1999 was $22,063, or an effective tax rate
of 39.0%, compared to $17,495, or an effective tax rate of 39.6% for the nine
month period ended December 31, 1998. The decline in tax rate for the nine month
period is primarily a result of improved profitability in Brazil and Mexico. The
rate decrease for the three month period resulted from the reduction in the nine
month rate.

         Net income for Third Quarter 2000 was $12,305 compared to $9,605 in
Third Quarter 1999, an increase of 28.1%. Net income for the nine month period
ended December 31, 1999 was $34,522 compared to $26,653 for the nine month
period ended December 31, 1998, an increase of 29.5%. This growth was primarily
due to strong revenue growth, the Company's ability to leverage its existing
cost structure and the successful expansion by merger of the Company's on-site
support offering.

LIQUIDITY AND CAPITAL RESOURCES

         In Third Quarter 2000, the Company's net proceeds from borrowings
increased by $23,575 and by $70,517 for the three and nine month periods ended
December 31, 1999, respectively, as a result of borrowings used to finance the
repurchase of its Common Stock and to continue expansion by merger of its
on-site support providers. As of December 31, 1999, the Company had cash and
cash equivalents of $5,194, working capital of $96,495, and total debt of
$75,511.

         On August 27, 1999, the Company signed an agreement providing an
additional $30 million revolving credit facility with Mellon Bank, N.A. (the
"New Mellon Facility"). The New Mellon Facility provides additional liquidity
for future stock repurchases and operations. The terms of the New Mellon
Facility are substantially similar to the existing Mellon Credit Facility except
that the New Mellon Facility will expire on August 25, 2000. Upon its
expiration, the Company has the option to convert the facility into a three-year
term note with substantially similar terms.

         The Company's total debt at December 31, 1999 was comprised of $46,800
under the Mellon Credit Facility, dated as of February 12, 1999, between the
Company and Mellon Bank, N.A., $24,300 under the New Mellon Facility, and $4,411
of various other loans. The weighted average interest rate on all indebtedness
of the Company as of December 31, 1999 was approximately 6.6% compared to 6.0%
as of December 31, 1998. In addition, at December 31, 1999, the Company had
$1,200 of letters of credit outstanding and $6,700 of additional funds available
under the Mellon Credit Facility and the New Mellon Facility.

         In January 2000, the Company engaged Mellon Bank N.A. to act as its
agent in arranging syndication of a $150,000 revolving credit facility (the
"Syndicated Facility"). The Syndicated Facility will be used to pay off the
Mellon Credit Facility and the New Mellon Facility and for general corporate
purposes. At that time, Mellon Bank also extended an additional temporary
revolving credit facility in the amount of $30,000 (the "Bridge Financing") with
terms substantially similar to those of the Mellon Credit Facility and the New
Mellon Facility. The Bridge Financing expires upon closing the Syndicated
Facility and will be paid with proceeds of the Syndicated Facility.

         On March 31, 1999, the Company announced its intention to repurchase up
to 1 million shares of its Common Stock. As of June 1999, the Company had
repurchased all 1 million shares in the open market at a total cost of $41,981.
On July 15, 1999, the Company announced its intention to




                                       18
<PAGE>   19



repurchase an additional 500,000 shares of its Common Stock. As of November
1999, the Company had repurchased all 500,000 shares under this plan at
prevailing market rates for an aggregate purchase price of $25,273. Funding for
these stock repurchases came from existing cash flow and borrowings under the
Mellon Credit Facility and New Mellon Facility.

         The Company has operations, customers and suppliers worldwide, thereby
exposing the Company's financial results to foreign currency fluctuations. In an
effort to reduce this risk, the Company generally sells and purchases inventory
based on prices denominated in U.S. dollars. Intercompany sales to subsidiaries
are generally denominated in the subsidiaries' local currency, although
intercompany sales to the Company's subsidiaries in Brazil and Mexico are
denominated in U.S. dollars. The gains and losses resulting from the revaluation
of the intercompany balances denominated in foreign currencies are recorded to
gross profit to the extent the intercompany transaction resulted from an
intercompany sale of inventory.

         The Company has entered and will continue in the future, on a selective
basis, to enter into forward exchange contracts to reduce the foreign currency
exposure related to certain intercompany transactions. On a monthly basis, the
open contracts are revalued to the current exchange rates and the resulting
gains and losses are recorded in other income. These gains and losses offset the
revaluation of the related foreign currency denominated receivables discussed
above. At December 31, 1999, the open foreign exchange contracts were in Yen,
Euro, Sterling Pound and Canadian Dollars. These open contracts were valued at
approximately $4,373, with contract rates ranging from 102.02 to 102.02 Yen per
U.S. dollar, 1.0235 to 1.0245 Euro to U.S. dollar, 1.6237 to 1.6273 Sterling
Pound per U.S. dollar and 1.4791 to 1.4804 Canadian dollar per U.S. dollar, and
the last contract will expire in February 2000. The effect of these contracts on
net income for the three-and nine-month periods ended December 31, 1999 was not
material.

         The Company believes that its cash flow from operations and existing
credit facilities will be sufficient to satisfy its liquidity needs for the
foreseeable future.

YEAR 2000

         The year 2000 issue refers to the potential for disruption to business
activities caused by system and processing failures of date-related
calculations, and is the result of computer-controlled systems using two digits
rather than four to define the applicable year. For example, computer programs
that have time-sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000. This could result in system failure or
miscalculation causing disruptions of operations, including among other things,
a temporary inability to process transactions, send invoices, or engage in
similar normal business activities.

         To date, the Company has not experienced any material business
disruptions related to the year 2000. Additionally, the Company has no reason to
believe that any material third parties with whom it deals have had any material
year 2000 issues. However, the Company cannot give assurance that it will
not experience any disruption due to year 2000 in the future. The Company will
continue to monitor its systems and third parties for any year 2000 problems.
Total costs for system modifications directly related to preparing systems for
the year 2000 were $400 and were expensed as incurred. The Company does not
expect to incur material cost related to year 2000 in the future.

CONVERSION TO THE EURO CURRENCY

         On January 1, 1999, certain members of the European Union established
fixed conversion rates between their existing currencies and the European
Union's common currency, the Euro. The Company conducts business in member
countries. The transition period for the introduction of the Euro will be
between January 1, 1999 and June 30, 2002. The Company is assessing the issues
involved with the introduction of the Euro, and it does not expect Euro
conversion to have a material impact on its operations or financial results.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company is exposed to market risks in the ordinary course of
business that include foreign currency exchange rates. In an effort to mitigate
the risk, the Company, on a selective basis, will enter into forward exchange
contracts. At December 31, 1999, the Company had open contracts valued at
approximately $4,406 and with a fair value of approximately $4,373.

                              BLACK BOX CORPORATION
                             1992 STOCK OPTION PLAN
                      (AS AMENDED THROUGH AUGUST 10, 1999)



         I.  PURPOSES
         ------------

         BLACK BOX CORPORATION (the "Company") desires to afford certain of its
key employees and the key employees of any subsidiary corporation or parent
corporation of the Company now existing or hereafter formed or acquired who are
responsible for the continued growth of the Company an opportunity to acquire a
proprietary interest in the Company, and thus to create in such key employees an
increased interest in and a greater concern for the welfare of the Company and
its subsidiaries.

         The Company, by means of this 1992 Stock Option Plan as originally
approved on November 11, 1992, and as further amended on May 10, 1994, August 9,
1994, August 7, 1995, August 12, 1996, August 13, 1997, February 3, 1998, August
10, 1998, and August 10, 1999 (the "Plan"), seeks to retain the services of
persons now holding key positions and to secure the services of persons capable
of filling such positions.

         The stock options ("Options") and stock appreciation rights ("Rights")
offered pursuant to the Plan are a matter of separate inducement and are not in
lieu of any salary or other compensation for the services of any key employee.

         The Options granted under the Plan are intended to be either incentive
stock options ("Incentive Options") within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), or options that do not
meet the requirements for Incentive Options ("Non-Qualified Options"), but the
Company makes no warranty as to the qualification of any Option as an Incentive
Option.

         II.  AMOUNT OF STOCK SUBJECT TO THE PLAN
         ----------------------------------------

         The total number of shares of common stock of the Company which may be
purchased or acquired pursuant to the exercise of Options or Rights granted
under the Plan shall not exceed, in the aggregate, 4,600,000 shares of the
authorized common stock, $.001 par value per share, of the Company (the
"Shares"), such number subject to adjustment as provided in Article XII hereof.
Shares that are the subject of Rights and related Options shall be counted only
once in determining whether the maximum number of Shares that may be purchased
or awarded under the Plan has been exceeded.

         Shares acquired under the Plan may be either authorized but unissued
Shares or Shares of issued stock held in the Company's treasury, or both, at the
discretion of the Company. If and to the extent that Options or Rights granted
under the Plan expire or terminate without having been exercised, the Shares
covered by such expired or terminated Options or Rights shall again become
available for award under the Plan.

         Except as provided in Article XIX and subject to Article II, the
Company may, from time to time during the period beginning on the date on which
the Company consummates an underwritten initial public offering of Shares (the
"Effective Date") and ending on November 30, 2002 (the "Termination Date"),
grant to certain key employees of the Company, or of any subsidiary corporation
or parent corporation of the Company now existing or hereafter formed or
acquired, Incentive Options and/or Non-Qualified Options and/or Rights under the
terms hereinafter set forth.

         Provisions of the Plan that pertain to Options or Rights granted to an
employee shall apply to Options, Rights or a combination thereof.

         As used in the Plan, the term "subsidiary corporation" and "parent
corporation" shall mean, respectively, a corporation coming within the
definition of such terms contained in Sections 424(f) and 424(e) of the Code.


                                       1
<PAGE>   2


         III.  ADMINISTRATION
         --------------------

         The board of directors of the Company (the "Board of Directors") shall
designate from among its members an option committee, which may be the
Compensation Committee of the Board of Directors (the "Committee"), to
administer the Plan. The Committee shall consist of no fewer than two members of
the Board of Directors, each of whom shall be a "disinterested person" within
the meaning of Rule 16b-3 (or any successor rule or regulation) promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). A
majority of the members of the Committee shall constitute a quorum, and the act
of a majority of the members of the Committee shall be the act of the Committee.
Any member of the Committee may be removed at any time either with or without
cause by resolution adopted by the Board of Directors, and any vacancy on the
Committee at any time may be filled by resolution adopted by the Board of
Directors.

         Subject to the express provisions of the Plan the Committee shall have
authority, in its discretion, to determine the employees to whom Options or
Rights shall be granted, the time when such Options or Rights shall be granted,
the number of Shares which shall be subject to each Option or Right, the
purchase price or exercise price of each Option or Right, the period(s) during
which such Options or Rights shall become exercisable (whether in whole or in
part) and the other terms and provisions thereof (which need not be identical).

         Subject to the express provisions of the Plan, the Committee also shall
have authority to construe the Plan and the Options and Rights granted
thereunder, to amend the Plan and the Options and Rights granted thereunder, to
prescribe, amend and rescind rules and regulations relating to the Plan, to
determine the terms and provisions of the Options (which need not be identical)
and Rights (which need not be identical) granted thereunder and to make all
other determinations necessary or advisable for administering the Plan. The
Committee also shall have the authority to require, in its discretion, as a
condition of the granting of any such Option or Right, that the employee agree
(i) not to sell or otherwise dispose of Shares acquired pursuant to the exercise
of such Option or Right for a period of six (6) months following the date of the
acquisition of such Option or Right and (ii) that in the event of termination of
employment of such employee, other than as a result of dismissal without cause,
such employee will not, for a period to be fixed at the time of the grant of the
Option or Right, enter into any other employment or participate directly or
indirectly in any other business or enterprise which is competitive with the
business of the Company or any subsidiary corporation or parent corporation of
the Company, or enter into any employment in which such employee will be called
upon to utilize special knowledge obtained through employment with the Company
or any subsidiary corporation or parent corporation thereof. In no event will an
employee who is subject to the reporting requirements of Section 16(a) of the
Exchange Act be entitled to sell or otherwise dispose of any Shares acquired
pursuant to exercise of any such Options or Rights for a period of six (6)
months from the date of the acquisition of such Options or Rights.

         The determination of the Committee on matters referred to in this
Article III shall be conclusive.

         The Committee may employ such legal counsel, consultants and agents as
it may deem desirable for the administration of the Plan and may rely upon any
opinion or computation received from any such legal counsel, consultant or
agent. Expenses incurred by the Committee in the engagement of such counsel,
consultant or agent shall be paid by the Company. No member or former member of
the Committee shall be liable for any action or determination made in good faith
with respect to the Plan or any award of Options or Rights granted hereunder.

         IV.  ELIGIBILITY
         ----------------

         Options and Rights may be granted only to salaried key employees of the
Company or of any subsidiary corporation or parent corporation of the Company,
except as hereinafter provided, and shall not be granted to any officer or
director who is not also a salaried key employee or to any member of the
Committee. Any person who shall have retired from active employment by the
Company or a subsidiary corporation or parent corporation thereof, although such
person shall have entered into a consulting contract with the Company or a
subsidiary corporation or parent corporation thereof, shall not be eligible to
receive an Option or a Right.

         The Plan does not create a right in any employee to participate in the
Plan, nor does it create a right in any employee to have any Options or Rights
granted to him or her.


                                       2
<PAGE>   3

         V.  OPTION PRICE AND PAYMENT
         ----------------------------

         The price for each Share purchasable under any Option granted hereunder
shall be such amount as the Committee shall, in its best judgment, determine to
be not less than one hundred percent (100%) of the fair market value per Share
at the date the Option is granted; provided, however, that in the case of an
Incentive Option granted to a person who, at the time such Option is granted,
owns shares of the Company or any subsidiary corporation or parent corporation
of the Company which possesses more than ten percent (10%) of the total combined
voting power of all classes of shares of the Company or of any subsidiary
corporation or parent corporation of the Company, the purchase price for each
Share shall be such amount as the Committee in its best judgment shall determine
to be not less than one hundred ten percent (110%) of the fair market value per
Share at the date the Option is granted. In determining stock ownership of an
employee for any purposes under the Plan, the rules of Section 424(d) of the
Code shall be applied, and the Committee may rely on representations of fact
made to it by the employee and believed by it to be true.

         If the Shares are listed on a national securities exchange in the
United States (which, for purposes of this Article V, shall be deemed to include
any last sale reported over-the-counter market), on any date on which the fair
market value per Share is to be determined, the fair market value per Share
shall be deemed to be the average of the high and low quotations at which such
Shares are sold on such national securities exchange on the date such Option is
granted. If the Shares are listed on a national securities exchange in the
United States on such date, but the Shares are not traded on such date, or such
national securities exchange is not open for business on such date, the fair
market value per Share shall be determined as of the closest preceding date on
which such exchange shall have been open for business and the Shares shall have
been traded. If the Shares are listed on more than one national securities
exchange in the United States on the date on which the fair market value per
Share is to be determined, the Committee shall determine which national
securities exchange shall be used for the purpose of determining the fair market
value per Share.

         If a public market exists for the Shares on any date on which the fair
market value per Share is to be determined but the Shares are not listed on a
national securities exchange in the United States, the fair market value per
Share shall be deemed to be the mean between the closing bid and asked
quotations in the over-the-counter market for the Shares on such date. If there
are no bid and asked quotations for the Shares on such date, the fair market
value per Share shall be deemed to be the mean between the closing bid and asked
quotations in the over-the-counter market for the Shares on the closest date
preceding such date for which such quotations are available.

         If no public market exists for the Shares on any date on which the fair
market value per Share is to be determined, the Committee shall, in its sole
discretion and best judgment, determine the fair market value of a Share.

         For purposes of this Plan, the determination by the Committee of the
fair market value of a Share shall be conclusive.

         Upon the exercise of an Option granted hereunder, the Company shall
cause the purchased Shares to be issued only when it shall have received the
full purchase price for the Shares in cash or by certified check; provided,
however, that in lieu of cash, the holder of an Option may, if and to the extent
the terms of such Option so provide and to the extent permitted by applicable
law, exercise an Option (i) in whole or in part, by delivering to the Company
shares of common stock of the Company (in proper form for transfer and
accompanied by all requisite stock transfer tax stamps or cash in lieu thereof)
owned by such holder having a fair market value equal to the exercise price
applicable to that portion of the Option being exercised by the delivery of such
Shares or (ii) in part, by delivering to the Company an executed promissory note
on such terms and conditions as the Committee shall determine, at the time of
grant, in its sole discretion; provided, however, that the principal amount of
such note shall not exceed eighty percent (80%) (or such lesser percentage as
would be permitted by applicable margin regulations) of the aggregate purchase
price of the Shares then being purchased pursuant to the exercise of such
Option. The fair market value of the stock so delivered shall be determined as
of the date immediately preceding the date on which the Option is exercised, or
as may be required in order to comply with or to conform to the requirements of
any applicable laws or regulations.


                                       3
<PAGE>   4


         VI.  USE OF PROCEEDS
         --------------------

         The cash proceeds of the sale of Shares pursuant to the Plan are to be
added to the general funds of the Company and used for its general corporate
purposes as the Board of Directors shall determine.

         VII.  TERM OF OPTIONS AND LIMITATIONS ON THE RIGHT OF EXERCISE
         --------------------------------------------------------------

         Any Option shall be exercisable at such times, in such amounts and
during such period or periods as the Committee shall determine at the date of
the grant of such Option; provided, however, that an Incentive Option shall not
be exercisable after the expiration of ten (10) years from the date such Option
is granted; and provided further that, in the case of an Incentive Option
granted to a person who, at the time such Option is granted, owns stock of the
Company or any subsidiary corporation or parent corporation of the Company
possessing more than ten percent (10%) of the total combined voting power of all
classes of stock of the Company or of any subsidiary corporation or parent
corporation of the Company, such Option shall not be exercisable after the
expiration of five (5) years from the date such Option is granted.

         Except to the extent otherwise provided under the Code, to the extent
that the aggregate fair market value of stock for which Incentive Options are
exercisable for the first time by an employee during any calendar year (under
all stock option plans of the Company and of any parent corporation or
subsidiary corporation of the Company) exceeds one hundred thousand dollars
($100,000), such Options shall be treated as Non-Qualified Options. For purposes
of this limitation, (i) the fair market value of stock is determined as of the
time the Option is granted, and (ii) the limitation will be applied by taking
into account Options in the order in which they were granted.

         Subject to the provisions of Article XVIII, the Committee shall have
the right to accelerate, in whole or in part, from time to time, conditionally
or unconditionally, rights to exercise any Option granted hereunder.

         To the extent that an Option is not exercised within the period of
exercisability specified therein, it shall expire as to the then unexercised
part.

         In no event shall an Option granted hereunder be exercised for a
fraction of a Share.

         VIII.  EXERCISE OF OPTIONS
         --------------------------

         Options granted under the Plan shall be exercised by the optionee as to
all or part of the Shares covered thereby by the giving of written notice of the
exercise thereof to the Corporate Secretary of the Company at the principal
business office of the Company, specifying the number of Shares to be purchased
and specifying a business day not more than fifteen (15) days from the date such
notice is given for the payment of the purchase price against delivery of the
Shares being purchased. Subject to the terms of Articles XIV, XVI, and XVII, the
Company shall cause certificates for the Shares so purchased to be delivered to
the optionee at the principal business office of the Company, against payment of
the full purchase price, on the date specified in the notice of exercise.

         IX.  STOCK APPRECIATION RIGHTS
         ------------------------------

         In the discretion of the Committee, a Right may be granted (i) alone,
(ii) simultaneously with the grant of an Option (either Incentive or
Non-Qualified) and in conjunction therewith or in the alternative thereto or
(iii) subsequent to the grant of a Non-Qualified Option and in conjunction
therewith or in the alternative thereto.

         The exercise price of a Right granted alone shall be determined by the
Committee but shall not be less than one hundred percent (100%) of the fair
market value of one Share on the date of grant of such Right. A Right granted
simultaneously with or subsequent to the grant of an Option and in conjunction
therewith or in the alternative thereto shall have the same exercise price as
the related Option, shall be transferable only upon the same terms and
conditions as the related Option, and shall be exercisable only to the same
extent as the related Option; provided, however, that a Right, by its terms,
shall be exercisable only when the fair market value of the Shares subject to
the Right and related Option exceeds the exercise price thereof.


                                       4
<PAGE>   5

         Upon exercise of a Right granted simultaneously with or subsequent to
an Option and in the alternative thereto, the number of Shares for which the
related Option shall be exercisable shall be reduced by the number of Shares for
which the Right shall have been exercised. The number of Shares for which a
Right shall be exercisable shall be reduced upon any exercise of a related
Option by the number of Shares for which such Option shall have been exercised.

         Any Right shall be exercisable upon such additional terms and
conditions as may from time to time be prescribed by the Committee.

         A Right shall entitle the holder upon exercise thereof to receive from
the Company, upon a written request filed with the Secretary of the Company at
its principal offices (the "Request"), a number of Shares (with or without
restrictions as to substantial risk of forfeiture and transferability, as
determined by the Committee in its sole discretion), an amount of cash, or any
combination of Shares and cash, as specified in the Request (but subject to the
approval of the Committee in its sole discretion, at any time up to and
including the time of payment, as to the making of any cash payment), having an
aggregate fair market value equal to the product of (i) the excess of the fair
market value, on the day of such Request, of one Share over the exercise price
per share specified in such Right or its related Option, multiplied by (ii) the
number of Shares for which such Right shall be exercised.

         Any election by a holder of a Right to receive cash in full or partial
settlement of such Right, and any exercise of such Right for cash, may be made
only by a Request filed with the Corporate Secretary of the Company during the
period beginning on the third business day following the date of release for
publication by the Company of quarterly or annual summary statements of sales
and earnings and ending on the twelfth business day following such date. Within
thirty (30) days of the receipt by the Company of a Request to receive cash in
full or partial settlement of a Right or to exercise such Right for cash, the
Committee shall, in its sole discretion, either consent to or disapprove, in
whole or in part, such Request. A Request to receive cash in full or partial
settlement of a Right or to exercise a Right for cash may provide that, in the
event the Committee shall disapprove such Request, such Request shall be deemed
to be an exercise of such Right for Shares.

         If the Committee disapproves in whole or in part any election by a
holder to receive cash in full or partial settlement of a Right or to exercise
such Right for cash, such disapproval shall not affect such holder's right to
exercise such Right at a later date, to the extent that such Right shall be
otherwise exercisable, or to elect the form of payment at a later date, provided
that an election to receive cash upon such later exercise shall be subject to
the approval of the Committee. Additionally, such disapproval shall not affect
such holder's right to exercise any related Option or Options granted to such
holder under the Plan.

         A holder of a Right shall not be entitled to request or receive cash in
full or partial payment of such Right unless such Right shall have been held for
six (6) months from the date of acquisition to the date of cash settlement
thereof; provided, however, that such prohibition shall not apply if the holder
of such Right is not subject to the reporting requirements of Section 16(a) of
the Exchange Act. In no event will a holder of a Right who is subject to the
reporting requirements of Section 16(a) of the Exchange Act be entitled to make
such a request or receive cash in full or partial payment of such Right until
the Company shall have satisfied the informational requirements of Rule
16b-3(e)(1) promulgated under the Exchange Act for the specified one year
period.

         A Right shall be deemed exercised on the last day of its term, if not
otherwise exercised by the holder thereof, provided that the fair market value
of the Shares subject to the Right exceeds the exercise price thereof on such
date.

         For all purposes of this Article IX, the fair market value of Shares
shall be determined in accordance with the principles set forth in the Article
V.

         X.  NON-TRANSFERABILITY OF OPTIONS AND STOCK APPRECIATION RIGHTS
         ----------------------------------------------------------------

         Neither an Option nor a Right granted hereunder shall be transferable,
whether by operation of law or otherwise, other than by will or the laws of
descent and distribution, and any Option or Right granted hereunder shall be
exercisable during the lifetime of the holder only by such holder. Except to the
extent provided above,


                                       5
<PAGE>   6

Options and Rights may not be assigned, transferred, pledged, hypothecated or
disposed of in any way (whether by operation of law or otherwise) and shall not
be subject to execution, attachment or similar process.

         XI.  TERMINATION OF EMPLOYMENT
         ------------------------------

         Upon termination of employment of any employee with the Company and all
subsidiary corporations and parent corporations of the Company, an Option or
Right previously granted to the employee, unless otherwise specified by the
Committee in the Option or Right, shall, to the extent not theretofore
exercised, terminate and become null and void, provided that:

                  (a) if the employee shall die while in the employ of such
         corporation or during either the three (3) month or one (1) year
         period, whichever is applicable, specified in clause (b) below and at a
         time when such employee was entitled to exercise an Option or Right as
         herein provided, the legal representative of such employee, or such
         person who acquired such Option or Right by bequest or inheritance or
         by reason of the death of the employee, may, not later than one (1)
         year from the date of death, exercise such Option or Right, to the
         extent not theretofore exercised, in respect of any or all of such
         number of Shares as specified by the Committee in such Option or Right;
         and

                  (b) if the employment of an employee to whom such Option or
         Right shall have been granted shall terminate by reason of the
         employee's retirement (at such age or upon such conditions as shall be
         specified by the Board of Directors), disability (as described in
         Section 22(e)(3) of the Code) or dismissal by the employer other than
         for cause (as defined below), and while such employee is entitled to
         exercise such Option or Right as herein provided, such employee shall
         have the right to exercise such Option or Right so granted, to the
         extent not theretofore exercised, in respect of any or all of such
         number of Shares as specified by the Committee in such Option or Right,
         at any time up to and including (i) three (3) months after the date of
         such termination of employment in the case of termination by reason of
         retirement or dismissal other than for cause and (ii) one (1) year
         after the date of termination of employment in the case of termination
         by reason of disability.

         If an employee voluntarily terminates his or her employment, or is
discharged for cause, any Option or Right granted hereunder shall, unless
otherwise specified by the Committee in the Option or Right, forthwith terminate
with respect to any unexercised portion thereof.

         If an Option or Right granted hereunder shall be exercised by the legal
representative of a deceased or disabled employee or former employee, or by a
person who acquired an Option or Right granted hereunder by bequest or
inheritance or by reason of death of any employee or former employee, written
notice of such exercise shall be accompanied by a certified copy of letters
testamentary or equivalent proof of the right of such legal representative or
other person to exercise such Option or Right.

         For the purposes of the Plan, the term "for cause" shall mean (i) with
respect to an employee who is party to a written agreement with, or,
alternatively, participates in a compensation or benefit plan of the Company or
a subsidiary corporation or parent corporation of the Company, which agreement
or plan contains a definition of "for cause" or "cause" (or words of like
import) for purposes of termination of employment thereunder by the Company or
such subsidiary corporation or parent corporation of the Company, "for cause" or
"cause" as defined in the most recent of such agreements or plans, or (ii) in
all other cases, (a) the willful commission by an employee of a criminal or
other act that causes substantial economic damage to the Company or a subsidiary
corporation or parent corporation of the Company or substantial injury to the
business reputation of the Company or a subsidiary corporation or parent
corporation of the Company; (b) the commission by an employee of an act of fraud
in the performance of such employee's duties on behalf of the Company or a
subsidiary corporation or parent corporation of the Company; or (c) the
continuing willful failure of an employee to perform the duties of such employee
to the Company or a subsidiary corporation or parent corporation of the Company
(other than such failure resulting from the employee's incapacity due to
physical or mental illness) after written notice thereof (specifying the
particulars thereof in reasonable detail) and a reasonable opportunity to be
heard and cure such failure are given to the employee by the Board of Directors
or the Committee. For purposes of the Plan, no act, or failure to act, on the
employee's part shall be considered "willful" unless done or omitted to be done
by the employee not in good faith and without reasonable belief that the
employee's action or omission was in the best interest of the Company or a
subsidiary corporation or parent corporation of the Company.


                                       6
<PAGE>   7

         For the purposes of the Plan, an employment relationship shall be
deemed to exist between an individual and a corporation if, at the time of the
determination, the individual was an "employee" of such corporation for purposes
of Section 422(a) of the Code. If an individual is on military, sick leave or
other bona fide leave of absence, such individual shall be considered an
"employee" for purposes of the exercise of an Option or Right and shall be
entitled to exercise such Option or Right during such leave if the period of
such leave does not exceed 90 days, or, if longer, so long as the individual's
right to reemployment with the corporation granting the option (or a related
corporation) is guaranteed either by statute or by contract. If the period of
leave exceeds ninety (90) days, the employment relationship shall be deemed to
have terminated on the ninety-first (91st) day of such leave, unless the
individual's right to reemployment is guaranteed by statute or contract.

         A termination of employment shall not be deemed to occur by reason of
(i) the transfer of an employee from employment by the Company to employment by
a subsidiary corporation or a parent corporation of the Company or (ii) the
transfer of an employee from employment by a subsidiary corporation or a parent
corporation of the Company to employment by the Company or by another subsidiary
corporation or parent corporation of the Company. Furthermore, solely for
purposes of determining the rights and obligations under any outstanding Options
or Rights theretofore granted, in the event that the Company ceases to own,
directly or indirectly, stock possessing 50% or more of the total combined
voting power of all classes of stock of a subsidiary company by virtue of a
recapitalization, stock dividend, stock split, split-up, spin-off, combination
of shares or other like change in capital structure of the Company, the
Committee may determine that employment by such former subsidiary (or any parent
or subsidiary company of such subsidiary) shall continue to be deemed to be
employment by the Company for purposes of the Plan.

         In the event of the complete liquidation or dissolution of a subsidiary
corporation, or in the event that the Company ceases to own, directly or
indirectly, stock possessing 50% or more of the total combined voting power of
all classes of stock of such corporation, any unexercised Options or Rights
theretofore granted to any person employed by such subsidiary corporation will
be deemed canceled unless such person is employed by the Company or by any
parent corporation or another subsidiary corporation after the occurrence of
such event. In the event an Option or Right is to be canceled pursuant to the
provisions of the previous sentence, notice of such cancellation will be given
to each employee holding unexercised Options or Rights and such holder will have
the right to exercise such Options or Rights in full (without regard to any
limitation set forth or imposed pursuant to Article VII) during the 30 day
period following notice of such cancellation.

         Notwithstanding anything to the contrary contained in this Article XI,
in no event, however, shall any person be entitled to exercise any Option or
Right after the expiration of the period of exercisability of such Option or
Right as specified therein.

         XII.  ADJUSTMENT OF SHARES; EFFECT OF CERTAIN TRANSACTIONS
         ----------------------------------------------------------

         In the event of any change in the outstanding Shares through merger,
consolidation, reorganization, recapitalization, stock dividend, stock split,
split-up, split-off, spin-off, combination of shares, exchange of shares,
issuance of rights to subscribe for Shares, or other like change in capital
structure of the Company, the Committee shall make such adjustment to each
outstanding Option and Right that it, in its sole discretion, deems appropriate.
The term "Shares" after any such change shall refer to the securities, cash
and/or property then receivable upon exercise of an Option or Right. In
addition, in the event of any such change, the Committee shall make any further
adjustments as may be appropriate to the maximum number of Shares which may be
acquired under the Plan pursuant to the exercise of Options and Rights, the
maximum number of Shares which may be so acquired by one employee and the number
of Shares and prices per Share subject to outstanding Options and Rights as
shall be equitable to prevent dilution or enlargement of rights under such
Options or Rights, and the determination of the Committee as to these matters
shall be conclusive. Notwithstanding the foregoing, (i) each such adjustment
with respect to an Incentive Option and any related Right shall comply with the
rules of Section 424(a) of the Code and (ii) in no event shall any adjustment be
made which would render any Incentive Option granted hereunder to be other than
an "incentive stock option" for purposes of Section 422 of the Code.

         In the event of a "change in control" of the Company, all then
outstanding Options and Rights shall immediately become exercisable. For
purposes of the Plan, a "change in control" of the Company occurs if: (a) any
"Person" (as such term is used in Sections 13(d) and 14(d)(2) of the Exchange
Act), other than OdysseY


                                       7
<PAGE>   8

Partners, L.P. and its affiliates (which, for purposes of this Article XII only,
is deemed to include E.R. Yost) is or becomes the "beneficial owner" (as defined
in Rule 13d-3 under the Exchange Act), directly or indirectly of securities of
the Company representing (i) 50% or more of the combined voting power of the
Company's then-outstanding securities; or (ii) 25% or more but less than 50% of
the combined voting power of the Company's then-outstanding securities if such
transaction(s) giving rise to such beneficial ownership are not approved by the
Company's Board of Directors; or (b) at any time a majority of the members of
the Board of Directors has been elected or designated by any Person, other than
Odyssey Partners, L.P. and its affiliates (which, for purposes of this Article
XII only, is deemed to include E.R. Yost); or (c) the Board of Directors shall
approve a sale of all or substantially all of the assets of the Company or any
merger, consolidation, issuance of securities or purchase of assets, in all
cases other than to or with Odyssey Partners, L.P. or its affiliates (which, for
purposes of this Article XII only, is deemed to include E.R. Yost), the result
of which would be the occurrence of any event described in clause (a) or (b)
above.

         The Committee, in its discretion, may determine that, upon the
occurrence of a transaction described in the preceding paragraph, each Option or
Right outstanding hereunder shall terminate within a specified number of days
after notice to the holder, and such holder shall receive, with respect to each
Share subject to such Option or Right, cash in an amount equal to the excess of
the fair market value of such Shares immediately prior to the occurrence of such
transaction over the exercise price per share of such Option or Right. The
provisions contained in the preceding sentence shall be inapplicable to an
Option or Right granted within six (6) months before the occurrence of a
transaction described above if the holder of such Option or Right is subject to
the reporting requirements of Section 16(a) of the Exchange Act.

         XIII.  RIGHT TO TERMINATE EMPLOYMENT
         ------------------------------------

         The Plan shall not impose any obligation on the Company or on any
subsidiary corporation or parent corporation thereof to continue the employment
of any holder of Options or Rights and it shall not impose any obligation on the
part of any holder of Options or Rights to remain in the employ of the Company
or of any subsidiary corporation or parent corporation thereof.

         XIV.  PURCHASE FOR INVESTMENT
         -----------------------------

         Except for hereinafter provided, the Committee may require an employee,
as a condition upon exercise of any Option or Right granted hereunder, to
execute and deliver to the Company (a) stock powers with respect to Shares
underlying a particular Option or Right and required to be held by a custodian,
and (b) a written statement, in form satisfactory to the Committee in which the
employee represents and warrants that Shares are being acquired for such
person's own account for investment only and not with a view to the resale or
distribution thereof. The employee shall, at the request of the Committee, be
required to represent and warrant in writing that any subsequent resale or
distribution of Shares by the Employee shall be made only pursuant to either (i)
a Registration Statement on an appropriate form under the Securities Act of
1933, as amended (the "Securities Act"), which Registration Statement has become
effective and is current with regard to the Shares being sold, or (ii) a
specific exemption from the registration requirements of the Securities Act, but
in claiming such exemption the employee shall, prior to any offer of sale or
sale of such Shares, obtain a prior favorable written opinion of counsel, in
form and substance satisfactory to counsel for the Company, as to the
application of such exemption thereto. The foregoing restriction shall not apply
to (i) issuances by the Company so long as the Shares being issued are
registered under the Securities Act and a prospectus in respect thereof is
current or (ii) re-offerings of Shares by affiliates of the Company (as defined
in Rule 405 or any successor rule or regulation promulgated under the Securities
Act) if the Shares being re-offered are registered under the Securities Act and
a prospectus in respect thereof is current.

         XV.  ISSUE OF CERTIFICATES, LEGENDS, PAYMENT OF EXPENSES
         --------------------------------------------------------

         Upon any exercise of an Option or Right which may be granted hereunder
and, in the case of an Option, payment of the purchase price, a certificate or
certificates for the Shares shall be issued by the Company in the name of the
person exercising the Option or Right and shall be delivered to or upon the
order of such person.

         The Company may endorse such legend or legends upon the certificates
for Shares issued pursuant to the Plan and may issue such "stop transfer"
instructions to its transfer agent in respect of such Shares as, in its
discretion, it determines to be necessary or appropriate to (i) prevent a
violation of, or to perfect an exemption from, the registration requirements of
the Securities Act, (ii) implement the provisions of the Plan and any


                                       8
<PAGE>   9


agreement between the Company and the optionee or grantee with respect to such
Shares, or (iii) permit the Company to determine the occurrence of a
disqualifying disposition, as described in Section 421(b) of the Code, of Shares
transferred upon exercise of an Incentive Option granted under the Plan.

         The Company shall pay all issue or transfer taxes with respect to the
issuance of transfer of Shares, as well as all fees and expenses necessarily
incurred by the Company in connection with such issuance or transfer, except
fees and expenses which may be necessitated by the filing or amending of a
Registration Statement under the Securities Act, which fees and expenses shall
be borne by the recipient of the Shares unless such Registration Statement has
been filed by the Company for its own corporate purposes (and the Company so
states) in which event the recipient of the Shares shall bear only fees and
expenses as are attributable solely to the inclusion of the Shares he or she
received in the Registration Statement.

         All Shares issued as provided herein shall be fully paid and
non-assessable to the extent permitted by law.

         XVI.  WITHHOLDING TAXES
         -----------------------

         The Company may require an employee exercising a Right or Non-Qualified
Option granted hereunder, or disposing of Shares acquired pursuant to the
exercise of an Incentive Option in a disqualifying disposition (within the
meaning of Section 421(b) of the Code), to reimburse the corporation that
employs such employee for any taxes required by any government to be withheld or
otherwise deducted and paid by such corporation in respect of the issuance or
disposition of such Shares. In lieu thereof, the corporation that employs such
employee shall have the right to withhold the amount of such taxes from any
other sums due or to become due from such corporation to the employee upon such
terms and conditions as the Committee shall prescribe. The corporation that
employs such employee may, in its discretion, hold the stock certificate to
which such employee is entitled upon the exercise of an Option as security for
the payment of such withholding tax liability, until cash sufficient to pay that
liability has been accumulated. In addition, at any time that the Company
becomes subject to a withholding obligation under applicable law with respect to
the exercise of a Right or Non-Qualified Option (the "Tax Date"), except as set
forth below, a holder of a Right or Non-Qualified Option may elect to satisfy,
in whole or in part, the holder's related personal tax liabilities (an
"Election") by (i) directing the Company to withhold from Shares issuable in the
related exercise either a specified number of Shares or Shares having a
specified value (in each case not in excess of the related personal tax
liabilities), (ii) tendering Shares previously issued pursuant to the exercise
of an Option or Right or other Shares of the Company's common stock owned by the
holder or (iii) combining any or all of the foregoing options in any fashion. An
Election shall be irrevocable. The withheld Shares and other Shares tendered in
payment shall be valued at their fair market value (determined in accordance
with the principles set forth in Article V of the Plan) on the Tax Date. The
Committee may disapprove of any Election, suspend or terminate the right to make
Elections or provide that the right to make Elections shall not apply to
particular Shares or exercises. The Committee may prescribe additional rules, in
its discretion, to permit a holder of an Option or Right who is subject to the
reporting requirements of Section 16(a) of the Exchange Act to effect such tax
withholding in compliance with the Rules promulgated under Section 16 of the
Exchange Act and the positions of the staff of the Securities and Exchange
Commission expressed in no-action or interpretative letters exempting such tax
withholding transactions from liability under Section 16(b) of the Exchange Act.
The Committee may also impose any additional conditions or restrictions on the
right to make an Election as it shall deem appropriate.

         XVII.  LISTING OF SHARES AND RELATED MATTERS
         --------------------------------------------

         The Committee may delay any award, issuance or delivery of Shares if it
determines that listing, registration or qualification of Shares or the consent
or approval of any governmental regulatory body is necessary or desirable as a
condition of, or in connection with, the sale or purchase of Shares under the
Plan, until such listing, registration, qualification, consent or approval shall
have been effected or obtained, or otherwise provided for, free of any
conditions not acceptable to the Committee.

         XVIII.  AMENDMENT OF THE PLAN
         -----------------------------

         The Board of Directors or the Committee, as the case may be, may, from
time to time, amend the Plan, provided that no amendment shall be made, without
the approval of the stockholders of the Company, that will (i) increase the
total number of Shares reserved for Options under the Plan (other than an
increase resulting


                                       9
<PAGE>   10

from an adjustment provided for in Article XII), (ii) reduce the exercise price
of any Incentive Option granted hereunder below the price required by Article V,
(iii) modify the provisions of the Plan relating to eligibility, or (iv)
materially increase the benefits accruing to participants under the Plan. The
Board of Directors or the Committee, as the case may be, shall be authorized to
amend the Plan and the Options granted thereunder to permit the Incentive
Options granted thereunder to qualify as incentive stock options within the
meaning of Section 422 of the Code. The rights and obligations under any Option
or Right granted before amendment of the Plan or any unexercised portion of such
Option or Right shall not be adversely affected by amendment of the Plan, Option
or Right without the consent of the holder of such Option or Right.

         XIX.  TERMINATION OR SUSPENSION OF THE PLAN
         -------------------------------------------

         The Board of Directors may at any time suspend or terminate the Plan.
The Plan, unless sooner terminated by action of the Board of Directors, shall
terminate at the close of business on the Termination Date. Options and Rights
may not be granted while the Plan is suspended or after it is terminated. Rights
and obligations under any Option or Right granted while the Plan is in effect
shall not be altered or impaired by suspension or termination of the Plan,
except upon the consent of the person to whom the Option or Right was granted.
The power of the Committee to construe and administer any Options or Rights
granted prior to the termination or suspension of the Plan under Article III
nevertheless shall continue after such termination or during such suspension.

         XX.  GOVERNING LAW
         ------------------

         The Plan, such Options and Rights as may be granted thereunder and all
related matters shall be governed by, and construed and enforced in accordance
with, the laws of the State of Delaware from time to time obtaining.

         XXI.  PARTIAL INVALIDITY
         ------------------------

         The invalidity or illegibility of any provision hereof shall not be
deemed to affect the validity of any other provision.

         XXII.  EFFECTIVE DATE
         ---------------------
         This Plan became effective at 5:30 P.M., New York City Time, on the
Effective Date.

                                                                   Exhibit 10.2


                              BLACK BOX CORPORATION
                         1992 DIRECTOR STOCK OPTION PLAN
                      (AS AMENDED THROUGH AUGUST 10, 1999)



         I.  PURPOSES
         ------------

         BLACK BOX CORPORATION (the "Company") desires to afford certain of its
directors, and certain directors of any subsidiary corporation or parent
corporation of the Company now existing or hereafter formed or acquired an
opportunity to acquire a proprietary interest in the Company, and thus to create
in such directors an increased interest in and a greater concern for the welfare
of the Company and its subsidiaries.

         The Company, by means of this 1992 Director Stock Option Plan, as
originally approved on November 11, 1992, and as further amended on, May
10,1994, August 9, 1994, August 7, 1995, August 12, 1996, August 13, 1997,
September 2, 1997, February 3, 1998, May 5, 1998, August 10, 1998, and August
10, 1999 (the "Plan"), seeks to retain the services of certain persons now
serving as directors and to secure the services of persons capable of filling
such positions.

         The stock options ("Options") and stock appreciation rights ("Rights")
offered pursuant to the Plan are a matter of separate inducement and are not in
lieu of any salary or other compensation for the services of any director.

         The Options granted under the Plan are intended to be options that do
not meet the requirements for incentive stock options within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code").

         II.  AMOUNT OF STOCK SUBJECT TO THE PLAN
         ----------------------------------------

         The total number of shares of common stock of the Company which may be
purchased or acquired pursuant to the exercise of Options or Rights granted
under the Plan shall not exceed, in the aggregate, 150,000 shares of the
authorized common stock, $.001 par value per share, of the Company (the
"Shares"), such number subject to adjustment as provided in Article XII hereof.
Shares that are the subject of Rights and related Options shall be counted only
once in determining whether the maximum number of Shares that may be purchased
or awarded under the Plan has been exceeded.

         Shares acquired under the Plan may be either authorized but unissued
Shares or Shares of issued stock held in the Company's treasury, or both, at the
discretion of the Company. If and to the extent that Options or Rights granted
under the Plan expire or terminate without having been exercised, the Shares
covered by such expired or terminated Options or Rights shall again become
available for award under the Plan.

         Except as provided in Article XVIII and subject to Article II, the
Company may, from time to time during the period beginning on the date on which
the Company consummates an underwritten initial public offering of Shares (the
"Effective Date") and ending on November 30, 2002 (the "Termination Date"),
grant to certain directors of the Company, or of any subsidiary corporation or
parent corporation of the Company now existing or hereafter formed or acquired,
Options and/or Rights under the terms hereinafter set forth.

         Provisions of the Plan that pertain to Options or Rights granted to a
director shall apply to Options, Rights or a combination thereof.

         As used in the Plan, the term "subsidiary corporation" and "parent
corporation" shall mean, respectively, a corporation coming within the
definition of such terms contained in Sections 424(f) and 424(e) of the Code.

         III.  ADMINISTRATION
         --------------------

         The board of directors of the Company (the "Board") may designate from
among its members a director stock option committee, (the "Committee") to
administer the Plan. The Committee shall consist of no fewer than two members of
the Board. A majority of the members of the Committee shall constitute a quorum,


<PAGE>   2


and the act of a majority of the members of the Committee shall be the act of
the Committee. Any member of the Committee may be removed at any time either
with or without cause by resolution adopted by the Board, and any vacancy on the
Committee at any time may be filled by resolution adopted by the Board.

         Subject to the express provisions of the Plan, the Board and the
Committee shall have authority, in their discretion, to determine the directors
to whom Options or Rights shall be granted, the time when such Options or Rights
shall be granted, the number of Shares which shall be subject to each Option or
Right, the purchase price or exercise price of each Option or Right, the
period(s) during which such Options or Rights shall become exercisable (whether
in whole or in part) and the other terms and provisions thereof (which need not
be identical).

         Subject to the express provisions of the Plan, the Board and the
Committee also shall have authority to construe the Plan and the Options and
Rights granted thereunder, to amend the Plan and the Options and Rights granted
thereunder, to prescribe, amend and rescind rules and regulations relating to
the Plan, to determine the terms and provisions of the Options (which need not
be identical) and Rights (which need not be identical) granted thereunder and to
make all other determinations necessary or advisable for administering the Plan.
The Board and the Committee also shall have the authority to require, in its
discretion, as a condition of the granting of any such Option or Right, that the
director agree (i) not to sell or otherwise dispose of Shares acquired pursuant
to the exercise of such Option or Right for a period of six (6) months following
the date of the acquisition of such Option or Right and (ii) that in the event
of termination of service of such director, other than as a result of removal
without cause, such director will not, for a period to be fixed at the time of
the grant of the Option or Right, enter into any other employment or participate
directly or indirectly in any other business or enterprise which is competitive
with the business of the Company or any subsidiary corporation or parent
corporation of the Company, or enter into any employment in which such director
will be called upon to utilize special knowledge obtained through service as a
director of the Company or any subsidiary corporation or parent corporation
thereof. In no event will a director who is subject to the reporting
requirements of Section 16(a) of the Exchange Act be entitled to sell or
otherwise dispose of any Shares acquired pursuant to exercise of any such
Options or Rights for a period of six (6) months from the date of the
acquisition of such Options or Rights.

         The determination of the Board or Committee on matters referred to in
this Article III shall be conclusive.

         The Board or Committee may employ such legal counsel, consultants and
agents as it may deem desirable for the administration of the Plan and may rely
upon any opinion or computation received from any such legal counsel, consultant
or agent. Expenses incurred in the engagement of such counsel, consultant or
agent shall be paid by the Company. No member or former member of the Board or
Committee shall be liable for any action or determination made in good faith
with respect to the Plan or any award of Options or Rights granted hereunder.

         IV.  ELIGIBILITY
         ----------------

         Options and Rights may be granted only to non-employee directors of the
Company or of any subsidiary corporation or parent corporation of the Company,
except as hereinafter provided. Any person who shall cease to serve on the Board
or a subsidiary corporation or parent corporation thereof, although such person
shall have entered into a consulting contract with the Company or a subsidiary
corporation or parent corporation thereof, shall not be eligible to receive an
Option or a Right.

         The Plan does not create a right in any director to participate in the
Plan, nor does it create a right in any director to have any Options or Rights
granted to him or her.

         V.  OPTION PRICE AND PAYMENT
         ----------------------------

         The price for each Share purchasable under any Option granted hereunder
shall be such amount as the Committee shall deem appropriate but not less than
one hundred percent (100%) of the fair market value per share at the date the
Option is granted.

<PAGE>   3

         If the Shares are listed on a national securities exchange in the
United States (which, for purposes of this Article V, shall be deemed to include
any last sale reported over-the-counter market), on any date on which the fair
market value per Share shall be deemed to be the average of the high and low
quotations at which such Shares are sold on such national securities exchange on
the date such Option is granted. If the Shares are listed on a national
securities exchange in the United States on such date, but the Shares are not
traded on such date, or such national securities exchange is not open for
business on such date, the fair market value per Share shall be determined as of
the closest preceding date on which such exchange shall have been open for
business and the Shares shall have been traded. If the Shares are listed on more
than one national securities exchange in the United States on the date on which
the fair market value per Share is to be determined, the Committee shall
determine which national securities exchange shall be used for the purpose of
determining the fair market value per Share.

         If a public market exists for the Shares on any date on which the fair
market value per Share is to be determined but the Shares are not listed on a
national securities exchange in the United States, the fair market value per
Share shall be deemed to be the mean between the closing bid and asked
quotations in the over-the-counter market for the Shares on such date. If there
are no bid and asked quotations for the Shares on such date, the fair market
value per Share shall be deemed to be the mean between the closing bid and asked
quotations in the over-the-counter market for the Shares on the closest date
preceding such date for which such quotations are available.

         If no public market exists for the Shares on any date on which the fair
market value per Share is to be determined, the Committee shall, in its sole
discretion and best judgment, determine the fair market value of a Share.

         For purposes of this Plan, the determination by the Committee of the
fair market value of a Share shall be conclusive.

         Upon the exercise of an Option granted hereunder, the Company shall
cause the purchased Shares to be issued only when it shall have received the
full purchase price for the Shares in cash or by certified check; provided,
however, that in lieu of cash, the holder of an Option may, if and to the extent
the terms of such Option so provide and to the extent permitted by applicable
law, exercise an Option (a) in whole or in part, by delivering to the Company
shares of common stock of the Company (in proper form for transfer and
accompanied by all requisite stock transfer tax stamps or cash in lieu thereof)
owned by such holder having a fair market value equal to the exercise price
applicable to that portion of the Option being exercised by the delivery of such
Shares or (b) in part, by delivering to the Company an executed promissory note
on such terms and conditions as the Committee shall determine, at the time of
grant, in its sole discretion; provided, however, that the principal amount of
such note shall not exceed eighty percent (80%) (or such lesser percentage as
would be permitted by applicable margin regulations) of the aggregate purchase
price of the Shares then being purchased pursuant to the exercise of such
Option. The fair market value of the stock so delivered shall be determined as
of the date immediately preceding the date on which the Option is exercised, or
as may be required in order to comply with or to conform to the requirements of
any applicable laws or regulations.

         VI.  USE OF PROCEEDS
         --------------------

         The cash proceeds of the sale of Shares pursuant to the Plan are to be
added to the general funds of the Company and used for its general Corporate
purposes as the Board shall determine.

         VII.  TERM OF OPTIONS AND LIMITATIONS ON THE RIGHT OF EXERCISE
         --------------------------------------------------------------

         Any Option shall be exercisable at such times, in such amounts and
during such period or periods as the Board or Committee shall determine at the
date of the grant of such Option.

         Subject to the provisions of Article XVIII, the Board or Committee
shall have the right to accelerate, in whole or in part, from time to time,
conditionally or unconditionally, rights to exercise any Option granted
hereunder.

         To the extent that an Option is not exercised within the period of
exercisability specified therein, it shall expire as to the then unexercised
part.


3
<PAGE>   4

         In no event shall an Option granted hereunder be exercised for a
fraction of a Share.

         VIII.  EXERCISE OF OPTIONS
         --------------------------

         Options granted under the Plan shall be exercised by the optionee as to
all or part of the Shares covered thereby by the giving of written notice of the
exercise thereof to the Corporate Secretary of the Company at the principal
business office of the Company, specifying the number of Shares to be purchased
and specifying a business day not more than fifteen (15) days from the date such
notice is given for the payment of the purchase price against delivery of the
Shares being purchased. Subject to the terms of Articles XIV, XVI, and XVII, the
Company shall cause certificates for the Shares so purchased to be delivered to
the optionee at the principal business office of the Company, against payment of
the full purchase price, on the date specified in the notice of exercise.

         IX.  STOCK APPRECIATION RIGHTS
         ------------------------------

         In the discretion of the Board or Committee, a Right may be granted (i)
alone, (ii) simultaneously with the grant of an Option and in conjunction
therewith or in the alternative thereto or (iii) subsequent to the grant of an
Option and in conjunction therewith or in the alternative thereto.

         The exercise price of a Right granted alone shall be determined by the
Board or Committee but shall not be less than one hundred percent (100%) of the
fair market value of one Share on the date of grant of such Right. A Right
granted simultaneously with or subsequent to the grant of an Option and in
conjunction therewith or in the alternative thereto shall have the same exercise
price as the related Option, shall be transferable only upon the same terms and
conditions as the related Option, and shall be exercisable only to the same
extent as the related Option; provided, however, that a Right, by its terms,
shall be exercisable only when the fair market value of the Shares subject to
the Right and related Option exceeds the exercise price thereof.

         Upon exercise of a Right granted simultaneously with or subsequent to
an Option and in the alternative thereto, the number of Shares for which the
related Option shall be exercisable shall be reduced by the number of Shares for
which the Right shall have been exercised. The number of Shares for which a
Right shall be exercisable shall be reduced upon any exercise of a related
Option by the number of Shares for which such Option shall have been exercised.

         Any Right shall be exercisable upon such additional terms and
conditions as may from time to time be prescribed by the Board or Committee.

         A Right shall entitle the holder upon exercise thereof to receive from
the Company, upon a written request filed with the Secretary of the Company at
its principal offices (the "Request"), a number of Shares (with or without
restrictions as to substantial risk of forfeiture and transferability, as
determined by the Board its sole discretion), an amount of cash, or any
combination of Shares and cash, as specified in the Request (but subject to the
approval of the Board in its sole discretion, at any time up to and including
the time to payment, as to the making of any cash payment), having an aggregate
fair market value equal to the product of (i) the excess of the fair market
value, on the day of such Request, of one Share over the exercise price per
share specified in such Right or its related Option, multiplied by (ii) the
number of Shares for which such Right shall be exercised.

         Any election by a holder of a Right to receive cash in full or partial
settlement of such Right, and any exercise of such Right for cash, may be made
only by a Request filed with the Corporate Secretary of the Company during the
period beginning on the third business day following the date of release for
publication by the Company of quarterly or annual summary statements of sales
and earnings and ending on the twelfth business day following such date. Within
thirty (30) days of the receipt by the Company of a Request to receive cash in
full or partial settlement of a Right or to exercise such Right for cash, the
Committee shall, in its sole discretion, either consent to or disapprove, in
whole or in part, such Request. A Request to receive cash in full or partial
settlement of a Right or to exercise a Right for cash may provide that, in the
event the Board shall disapprove such Request, such Request shall be deemed to
be an exercise of such Right for Shares.


4
<PAGE>   5


         If the Board disapproves in whole or in part any election by a holder
to receive cash in full or partial settlement of a Right or to exercise such
Right for cash, such disapproval shall not affect such holder's right to
exercise such Right at a later date, to the extent that such Right shall be
otherwise exercisable, or to elect the form of payment at a later date, provided
that an election to receive cash upon such later exercise shall be subject to
the approval of the Board. Additionally, such disapproval shall not affect such
holder's right to exercise any related Option or Options granted to such holder
under the Plan.

         A holder of a Right shall not be entitled to request or receive cash in
full or partial payment of such Right unless such Right shall have been held for
six (6) months from the date of acquisition to the date of cash settlement
thereof; provided, however, that such prohibition shall not apply if the holder
of such Right is not subject to the reporting requirements of Section 16(a) of
the Exchange Act.

         A Right shall be deemed exercised on the last day of its term, if not
otherwise exercised by the holder thereof, provided that the fair market value
of the Shares subject to the Right exceeds the exercise price thereof on such
date.

         For all purposes of this Article IX, the fair market value of Shares
shall be determined in accordance with the principles set forth in Article V.

         X.  NON-TRANSFERABILITY OF OPTIONS AND STOCK APPRECIATION RIGHTS
         ----------------------------------------------------------------

         Neither an Option nor a Right granted hereunder shall be transferable,
whether by operation of law or otherwise, other than by will or the law of
descent and distribution, and any Option or Right granted hereunder shall be
exercisable during the lifetime of the holder only by such holder. Except to the
extent provided above, Options and Rights may not be assigned, transferred,
pledged, hypothecated or disposed of in any way (whether by operation of law or
otherwise) and shall not be subject to execution, attachment or similar process.

         XI.  TERMINATION OF EMPLOYMENT
         ------------------------------

         Upon the cessation of such person's status as a director of the Company
and all subsidiary corporations and parent corporations of the Company, an
Option or Right previously granted to the director, unless otherwise specified
by the Board or Committee in the Option or Right, shall, to the extent not
theretofore exercised, terminate and become null and void, provided that:

                  (a) if the director shall die while serving as a director of
         such corporation or during either the three (3) month or one (1) year
         period, whichever is applicable, specified in clause (b) below and at a
         time when such director was entitled to exercise an Option or Right as
         herein provided, the legal representative of such director, or such
         person who acquired such Option or Right by bequest or inheritance or
         by reason of the death of the director, may, not later than one (1)
         year from the date of death, exercise such Option or Right, to the
         extent not theretofore exercised, in respect of any or all of such
         number of Shares as specified by the Board or Committee in such Option
         or Right; and

                  (b) if the service of any director to whom such Option or
         Right shall have been granted shall terminate by reason of the
         director's retirement (at such age or upon such conditions as shall be
         specified by the Board), disability (as described in Section 22(e)(3)
         of the Code) or removal other than for cause (as defined below), and
         while such director is entitled to exercise such Option or Right as
         herein provided, such director shall have the right to exercise such
         Option or Right so granted, to the extent not theretofore exercised, in
         respect of any or all of such number of Shares as specified by the
         Board or Committee in such Option or Right, at any time up to and
         including (i) three (3) months after the date of such termination of
         service in the case of termination by reason of retirement or removal
         other than for cause and (ii) one (1) year after the date of
         termination of service in the case of termination by reason of
         disability.

         If a director voluntarily terminates his or her service, or is
discharged for cause, any Option or Right granted hereunder shall, unless
otherwise specified by the Board or Committee in the Option or Right, forthwith
terminate with respect to any unexercised portion thereof.


5
<PAGE>   6


         If an Option or Right granted hereunder shall be exercised by the legal
representative of a deceased or disabled director or former director, or by a
person who acquired an Option or Right granted hereunder by bequest or
inheritance or by reason of death of any director or former director, written
notice of such exercise shall be accompanied by a certified copy of letters
testamentary or equivalent proof of the right of such legal representative or
other person to exercise such Option or Right.

         For the purposes of the Plan, the term "for cause" shall mean (i) with
respect to a director who is party to a written agreement with, or,
alternatively, participates in a compensation or benefit plan of the Company or
a subsidiary corporation or parent corporation of the Company, which agreement
or plan contains a definition of "for cause" or "cause" (or words of like
import) for purposes of termination of service thereunder, "for cause" or
"cause" as defined in the most recent of such agreements or plans, or (ii) in
all other cases, as determined by the Board in its sole discretion, (a) the
willful commission by a director of a criminal or other act that causes or
probably will cause substantial economic damage to the Company or a subsidiary
corporation or parent corporation of the Company or substantial injury to the
business reputation of the Company or a subsidiary corporation or parent
corporation of the Company; (b) the commission by a director of an act of fraud
in the performance of such director's duties on behalf of the Company or a
subsidiary corporation or parent corporation of the Company; or (c) the
continuing willful failure of a director to perform the duties of such director
to the Company or a subsidiary corporation or parent corporation of the Company
(other than such failure resulting from the director's incapacity due to
physical or mental illness) after written notice thereof (specifying the
particulars thereof in reasonable detail) and a reasonable opportunity to be
heard and cure such failure are given to the director by the Board or the
Committee. For purposes of the Plan, no act, or failure to act, on the
director's part shall be considered "willful" unless done or omitted to be done
by the director not in good faith and without reasonable belief that the
director's action or omission was in the best interest of the Company or a
subsidiary corporation or parent corporation of the Company.

         In the event of the complete liquidation or dissolution of a subsidiary
corporation, or in the event that the Company ceases to own, directly or
indirectly, stock possessing 50% or more of the total combined voting power of
all classes of stock of such corporation, any unexercised Options or Rights
theretofore granted to any person who served as a director of such subsidiary
corporation will be deemed canceled unless such person serves on the Board or
board of directors of any parent corporation or another subsidiary corporation
after the occurrence of such event. In the event an Option or Right is to be
canceled pursuant to the provisions of the previous sentence, notice of such
cancellation will be given to each director holding unexercised Options or
Rights and such holder will have the right to exercise such Options or Rights in
full (without regard to any limitation set forth or imposed pursuant to Article
VII) during the 30 day period following notice of such cancellation.

         Notwithstanding anything to the contrary contained in this Article XI,
in no event, however, shall any person be entitled to exercise any Option or
Right after the expiration of the period of exercisability of such Option or
Right as specified therein.

         XII.  ADJUSTMENT OF SHARES; EFFECT OF CERTAIN TRANSACTIONS
         ----------------------------------------------------------

         In the event of any change in the outstanding Shares through merger,
consolidation, reorganization, recapitalization, stock dividend, stock split,
split-up, split-off, spin-off, combination of shares, exchange of shares, or
other like change in capital structure of the Company, the Board or Committee
shall make such adjustment to each outstanding Option and Right that it, in its
sole discretion, deems appropriate. The term "Shares" after any such change
shall refer to the securities, cash and/or property then receivable upon
exercise of an Option or Right. In addition, in the event of any such change,
the Board or Committee shall make any further adjustment as may be appropriate
to the maximum number of Shares which may be acquired under the Plan pursuant to
the exercise of Options and Rights, the maximum number of Shares which may be so
acquired by one director and the number of Shares and prices per Share subject
to outstanding Options and Rights as shall be equitable to prevent dilution or
enlargement of rights under such Options or Rights, and the determination of the
Board or Committee as to these matters shall be conclusive.

         In the event of a "change in control" of the Company, all then
outstanding Options and Rights shall immediately become exercisable. For
purposes of the Plan, a "change in control" of the Company occurs if: (a) any
"Person" (as such term is used in Sections 13(d) and 14(d)(2) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the


6
<PAGE>   7


Exchange Act), directly or indirectly, of securities of the Company representing
(i) 50% or more of the combined voting power of the Company's then-outstanding
securities; or (ii) 25% or more but less than 50% of the combined voting power
of the Company's then outstanding securities if such transaction(s) giving rise
to such beneficial ownership are not approved by the Board; or (b) at any time a
majority of the members of the Bard has been elected or designated by any
Person; or (c) the Board shall approve a sale of all or substantially all of the
assets, the result of which would be the occurrence of any event described in
clause (a) or (b) above.

         The Board or Committee, in its discretion, may determine that, upon the
occurrence of a transaction described in the preceding paragraph, each Option or
Right outstanding hereunder shall terminate within a specified number of days
after notice to the holder, and such holder shall receive, with respect to each
Share subject to such Option or Right, cash in an amount equal to the excess of
the fair market value of such Shares immediately prior to the occurrence of such
transaction over the exercise price per share of such Option or Right.

         XIII.  RIGHT TO TERMINATE EMPLOYMENT
         ------------------------------------

         The Plan shall not impose any obligation on the Company or on any
subsidiary corporation or parent corporation thereof to continue the service of
any holder of Options or Rights and it shall not impose any obligation on the
part of any holder of Options or Rights to remain in the service of the Company
or of any subsidiary corporation or parent corporation thereof.

         XIV.  PURCHASE FOR INVESTMENT
         -----------------------------

         Except for hereinafter provided, the Board or Committee may require a
director, as a condition upon exercise of any Option or Right granted hereunder,
to execute and deliver to the Company (a) stock powers with respect to Shares
underlying a particular Option or Right and required to be held by a custodian,
and (b) a written statement, in form satisfactory to the Board or Committee in
which the director represents and warrants that Shares are being acquired for
such person's own account for investment only and not with a view to the resale
or distribution thereof. The director shall, at the request of the Board or
Committee, be required to represent and warrant in writing that any subsequent
resale or distribution of Shares by the director shall be made only pursuant to
either (i) a Registration Statement on an appropriate form under the Securities
Act of 1933, as amended (the "Securities Act"), which Registration Statement has
become effective and is current with regard to the Shares being sold, or (ii) a
specific exemption from the registration requirements of the Securities Act, but
in claiming such exemption the director shall, prior to any offer of sale or
sale of such Shares, obtain a prior favorable written opinion of counsel, in
form and substance satisfactory to counsel for the Company, as to the
application of such exemption thereto. The foregoing restriction shall not apply
to (i) issuances by the Company so long as the Shares being issued are
registered under the Securities Act and a prospectus in respect thereof is
current or (ii) re-offerings of Shares by affiliates of the Company (as defined
in Rule 405 or any successor rule or regulation promulgated under the Securities
Act) if the Shares being re-offered are registered under the Securities Act and
a prospectus in respect thereof is current.

         XV.  ISSUE OF CERTIFICATES, LEGENDS, PAYMENT OF EXPENSES
         --------------------------------------------------------

         Upon any exercise of an Option or Right which may be granted hereunder
and, in the case of an Option, payment of the purchase price, a certificate or
certificates for the Shares shall be issued by the Company in the name of the
person exercising the Option or Right and shall be delivered to or upon the
order of such person.

         The Company may endorse such legend or legends upon the certificates
for Shares issued pursuant to the Plan and may issue such "stop transfer"
instructions to its transfer agent in respect of such Shares as, in its
discretion, it determines to be necessary or appropriate to (i) prevent a
violation of, or to perfect an exemption from, the registration requirements of
the Securities Act, (ii) implement the provisions of the Plan and any agreement
between the Company and the optionee or grantee with respect to such Shares.

         The Company shall pay all issue or transfer taxes with respect to the
issuance of transfer of Shares, as well as all fees and expenses necessarily
incurred by the Company in connection with such issuance or transfer, except
fees and expenses which may be necessitated by the filing or amending of a
Registration Statement under the Securities Act, which fees and expenses shall
be borne by the recipient of the Shares unless such Registration Statement has
been filed by the Company for its own corporate purposes (and the Company so


7
<PAGE>   8



states) in which event the recipient of the Shares shall bear only fees and
expenses as are attributable solely to the inclusion of the Shares he or she
receives in the Registration Statement.

         All Shares issued as provided herein shall be fully paid and
non-assessable to the extent permitted by law.

         XVI.  LISTING OF SHARES AND RELATED MATTERS
         -------------------------------------------

         The Board or Committee may delay any award, issuance or delivery of
Shares if it determines that listing, registration or qualification of Shares or
the consent or approval of any governmental regulatory body is necessary or
desirable as a condition of, or in connection with, the sale or purchase of
Shares under the Plan, until such listing, registration, qualification, consent
or approval shall have been effected or obtained, or otherwise provided for,
free of any conditions not acceptable to the Committee.

         XVII.  AMENDMENT OF THE PLAN
         ----------------------------

         The Board or the Committee, as the case may be, may, from time to time,
amend the Plan, provided that no amendment shall be made, without the approval
of the stockholders of the Company, that will (i) increase the total number of
Shares reserved for Options under the Plan (other than an increase resulting
from an adjustment provided for in Article XII), (ii) reduce the exercise price
of any Option granted hereunder below the price required by Article V, (iii)
modify the provisions of the Plan relating to eligibility, or (iv) materially
increase the benefits accruing to participants under the Plan. The rights and
obligations under any Option or Right granted before amendment of the Plan or
any unexercised portion of such Option or Right shall not be adversely affected
by amendment of the Plan, Option or Right without the consent of the holder of
such Option or Right.
`
         XVIII.  TERMINATION OR SUSPENSION OF THE PLAN
         ---------------------------------------------

         The Board may at any time suspend or terminate the Plan. The Plan,
unless sooner terminated by action of the Board, shall terminate at the close of
business on the Termination Date. Options and Rights may not be granted while
the Plan is suspended or after it is terminated. Rights and obligations under
any Option or Right granted while the Plan is in effect shall not be altered or
impaired by suspension or termination of the Plan, except upon the consent of
the person to whom the Option or Right was granted. The power of the Board or
Committee to construe and administer any Options or Rights granted prior to the
termination or suspension of the Plan under Article III nevertheless shall
continue after such termination or during such suspension.

         XIX.  GOVERNING LAW
         -------------------

         The Plan, such Options and Rights as may be granted thereunder and all
related matters shall be governed by, and construed and enforced in accordance
with, the laws of the State of Delaware from time to time obtaining.

         XX.  PARTIAL INVALIDITY
         -----------------------

         The invalidity or illegibility of any provision hereof shall not be
deemed to affect the validity of any other provision.

         XXI.  EFFECTIVE DATE
         --------------------
         The Plan shall become effective at 5:30 P.M., New York City Time, on
the Effective Date.
