PART I

ITEM 1. BUSINESS

GENERAL

Exponent, Inc., incorporated in Delaware in 1989 ("Exponent", and, together with its subsidiaries, the "Company"), through its principal operating subsidiaries, Exponent Failure Analysis Associates, Inc. ("FaAA"), Exponent Health Group, Inc. (formerly named Environmental Health Strategies, Inc.) ("EHG"), Exponent Environmental Group, Inc. (formerly named Performance Technologies, Incorporated) ("EEG") and BCS Wireless, Inc. ("BCS"), is a multidisciplinary organization of scientists, physicians, engineers, and business consultants performing in-depth scientific research and analysis in over 50 technical disciplines. BCS specializes in the design, installation and maintenance of wireless communication networks.

During fiscal 1996, the Company entered into the epidemiology arena with the acquisition of EHG. EHG, acquired on August 1, 1996, provides epidemiology advice and services on a wide variety of topics, including occupational and environmental health, pharmaceutical and medical device issues, and health- related consumer product safety.

During fiscal 1997, the Company continued implementing its strategy of growth and diversification through the acquisitions of BCS and EEG. BCS, acquired on January 4, 1997, specializes in the design, installation and maintenance of wireless communication networks. BCS is located in the greater Madison, Wisconsin area and has erected communication towers and provided related training and technical services for the telecommunications industry since 1981. EEG, acquired on May 16, 1997, is a consulting firm specializing in scientific solutions for complex environmental problems.

The Company sold one of its subsidiaries PLG, Inc. ("PLG") in the third quarter of fiscal 1997. The Company sold PLG based on management's assessment that the services PLG provided were no longer complementary to the Company's core business practice areas.

CLIENTS

General

The Company serves clients in manufacturing, transportation, utilities, energy, insurance, government, health, environmental and other sectors of the economy. Approximately 27% of the Company's revenues are derived from professional services provided to clients, organizations and insurers related to the transportation industry.

Many of the Company's engagements are initiated by lawyers or insurance companies whose clients anticipate or experience significant litigation over an alleged failure of their products, equipment or services. In other cases, the Company is engaged when a client requires independent testing of a product or requires specialized analysis regarding the likelihood of failures or techniques to prevent such failures.

Pricing and Terms of Engagements

The Company provides its services on either a fixed fee basis or on a "time and expenses" basis, charging hourly rates for each staff member involved in a project based on his or her skill and experience.

3

The Company's standard rates for professionals range from $30 to $650 per hour.

The Company's engagement agreements typically provide for monthly billing, require payment of the Company's invoices within 30 days of receipt, permit clients to terminate an engagement at any time and generally grant the Company ownership of intellectual property developed by the Company in the course of the engagement. Clients normally agree to indemnify Exponent's work and its personnel against liabilities arising out of the use or application of the results of the Company's work or recommendations.

HEALTH

Health services provide solutions to complex health problems from client consultation to clinical trials, health care evaluations, literature reviews and epidemiological studies. Health research includes reproductive effects, cancer, injuries, and health effects from workplace exposures, pharmacoepidemiolgy, and infectious disease control. Epidemiology, exposure assessment, and occupational medicine expertise is used to evaluate occupational and environmental health issues. Decision analysis, cost-benefit, risk-benefit, and outcome analysis is applied to assist health care companies in evaluating health care and with strategic planning and technology assessment.

Epidemiology is the science of studying disease within a population. Through the principles of epidemiology, analyses are performed on the interaction of host, agent, and environment to reach conclusions about the causes and occurrence of disease in human populations. Epidemiology services encompass designing and conducting occupational and environmental studies to evaluate the health effects of community and workplace exposures, work-related disease and injury; conducting decision analysis for alternative forms of medical treatments; designing, conducting, and interpreting clinical trials; consulting on product safety; and evaluating quality of health care.

Healthcare evaluation provides various approaches to accreditation, program evaluation and cost-effectiveness analyses. These approaches encompass statistical analysis; survey design and analysis; accreditation applications; cost-effectiveness analysis; performance indicators; accreditation requirements; outcome measurements; disease management; quality improvement; clinical practice guidelines; and program evaluation.

Medical technology assessments provide a comprehensive and independent assessment of medical devices and technologies. These assessments encompass clinical indications; materials selection; technology (engineering) review; FDA and other regulatory hurdles; target condition epidemiology (size of U.S. and worldwide market); pricing and reimbursement issues; cost effectiveness; complications and/or failure modes (liability); marketing strategy; and competing technologies.

Risk assessments and related analyses are a critical component of many environmental regulatory decisions. The results of such analyses help determine the need for and nature of remedial actions at hazardous waste sites, support the derivation of cleanup levels, and assist in permitting new facilities and developing closure plans for solid waste management units and facilities that are going out of service. Human health toxicology services encompass comprehensive multi-pathway risk assessments; screening-level risk evaluations; derivation of risk-based cleanup levels; deterministic and probabilistic exposure assessments; toxicity assessments and data evaluation; risk assessment strategy development and review; research and development to address sources of uncertainty; bio availability studies; fish consumption surveys and studies; and toxic tort, class action, and general litigation support.

HUMAN FACTORS

Analysis of human behavior and the limitations and capabilities of people as they use a product or participate in an activity can provide a better understanding of how accidents occur. The impact of warning labels, other safety information, and training on changing human behavior and reducing accidents is an active area of ongoing research. Human factors services encompasses the development of warnings and safety information for consumer, medical, and work- related products; analysis of the role of warnings in

6

particular accidents; use of injury/illness data to identify human behavior associated with accidents; use of risk analysis to quantify the safety of a product or activity; measurement of illuminance, luminance, and noise levels in work environments; measurement of human motor performance such as jumping ability, variation in gait, finger pinch strength and visual-motor control; testing of people's knowledge of hazards and comprehension of safety information; and analysis of user reaction to complex information and control systems.

HYDROLOGY

Hydrology is the science of water, its properties, phenomena, and distribution over the earth's surface. Exponent's hydrology services include the analysis of flood retention facilities (levees, dams, etc.) and the evaluation of the effects of flood water inundation on different types of structures. The services also extend to investigating the cause of hillside movement, slope erosion, and other soil movement that may be associated with flooding which may include distinguishing between damage due to catastrophe and damage that has been caused by or is related to long-term deterioration, foundation settlement, slope movement, initial construction defects, or normal expected behavior of a structure over time. In addition the hydrology practice provides property damage assessment, geotechnical services, as well as helps develop remedial repairs to address flood related distress. The hydrology services further include the development of master plans of drainage (MPD) to enable cities to coordinate all aspects of their flood control and surface water needs. This master drainage plan considers all types of storms and their attendant runoff and provides for safe transport of the waters off site.

INDUSTRIAL STRUCTURES

The Company has developed an expertise in power plant and industrial chimneys, not only as a designer, but as a consultant for maintenance and repair issues. The Industrial Structures Practice has developed "close to reality" computer programs which are frequently used for design of chimneys and other concrete towers that combine a high degree of safety with superior economics.

COMPETITION

The marketplace for the Company's services is fragmented and the Company faces different sources of competition in providing its various services. In addition, the services the Company provides to some of its clients can be performed in-house by those clients. However, because of liability and independence concerns, clients who have the capability to perform such services themselves often retain the Company or other independent consultants.

In each of the foregoing areas, the Company believes that the principal competitive factors are technical capability and breadth of services, ability to deliver services on a timely basis, professional reputation, knowledge of the litigation process, and the ability to offer fixed fee pricing. Although the Company believes it generally competes favorably in each of these areas, some of the Company's competitors may be able to provide services acceptable to the clients at significantly lower prices.

The Company generally believes that the barriers to entry in particular areas of engineering expertise are low and that for many of its technical disciplines, competition is increasing. In addition, the Company expects that as a result of these low barriers, competition may become more intense in other aspects of its business. In response to competitive forces in the marketplace, the Company continues to explore new markets for its various technical disciplines. Competitive pressures could reduce the market acceptance of the Company's services and result in price reductions.

EMPLOYEES

As of January 1, 1999, the Company employed approximately 707 full-time and part time employees, including approximately 378 engineering and scientific staff, 154 technical support staff, and 175 administrative and support staff.

The Company's future success depends on its continuing ability to attract and retain highly qualified technical and managerial personnel. Competition for such personnel is intense, and there can be no assurance that the Company will be able to retain its key managerial and technical employees or that it will be able to attract, assimilate or retain other highly qualified technical and managerial personnel in the future.

FACTORS AFFECTING OPERATING RESULTS AND MARKET PRICE OF STOCK

Exponent operates in a rapidly changing environment that involves a number of uncertainties, some of which are beyond the Company's control. These uncertainties include, but are not limited to, those mentioned elsewhere in this report, and the following:

ATTRACTION AND RETENTION OF KEY EMPLOYEES

The Company's business involves the delivery of professional services and is labor-intensive. The Company's success depends in large part upon its ability to attract, retain and motivate highly qualified technical and managerial personnel. Qualified personnel are in great demand and are likely to remain a limited resource for the foreseeable future. There can be no assurance that the Company can continue to attract sufficient numbers of highly qualified technical and managerial personnel and to retain existing employees. The loss of a significant number of the Company's employees could have a material adverse impact on the Company, including its ability to secure and complete engagements.

CUSTOMER CONCENTRATION

The Company currently derives, and believes that it will continue to derive, a significant portion of its revenues from clients, organizations and insurers related to the transportation industry. In 1998, transportation industry related engagements accounted for approximately 27% of the Company's revenues. The loss of any large client, organization or insurer related to the transportation industry could have a material adverse effect on the Company's business, financial condition and results of operations.

REGULATION

Public concern over health, safety and preservation of the environment has resulted in the enactment of a broad range of environmental laws and regulations by local, state and federal lawmakers and agencies. These laws and the implementing regulations affect nearly every industry, as well as the agencies of federal, state and local governments charged with their enforcement. To the extent changes in such laws, regulations and enforcement or other factors significantly reduce the exposures of manufacturers, owners, service providers and others to liability, the demand for environmental services may be significantly reduced.

COMPETITION

The markets for the Company's services are highly competitive. In addition, there are relatively low barriers to entry into the Company's markets and the Company has faced, and expects to continue to face, additional competition from new entrants into its markets. Competitive pressure could reduce the market acceptance of the Company's services and result in price reductions that could have a material adverse effect on the Company's business, financial condition and results of operations.

12

ABSENCE OF BACKLOG

Revenues are primarily derived from services provided in response to client request or events that occur without notice, and engagements, generally billed on a "time and expenses" basis, are terminable at any time by clients. As a result, backlog at any particular time is small in relation to its quarterly or annual revenues and is not a reliable indicator of revenues for any future periods. Revenues and operating margins for any particular quarter are generally affected by staffing mix, resource requirements and timing and size of engagements.

PROPERTIES

The Company currently subleases excess facilities in its Menlo Park, California headquarters that have lease terms that expire within the 2000-2001 time periods. In fiscal 1998 and 1997, miscellaneous rental income associated with these facilities amounted to approximately 32% and 26%, respectively of income from continuing operations before income taxes. Should these subleases not be extended, renewed or have their term options exercised, the loss of the miscellaneous rental income could have a material adverse effect on the Company's operating results.

VARIABILITY OF QUARTERLY FINANCIAL RESULTS

Variations in the Company's revenues and operating results occur from time to time as a result of a number of factors, such as the significance of client engagements commenced and completed during a quarter, the number of working days in a quarter, employee hiring and utilization rates, and integration of companies acquired. Because a high percentage of the Company's expenses, particularly personnel and facilities related, are relatively fixed in advance of any particular quarter, a variation in the timing of the initiation or the completion of client assignments, at or near the end of any quarter, can cause significant variations in operating results from quarter to quarter.

ITEM 2. PROPERTIES

The Company's headquarters office facilities consist of a 153,738 square foot building, with office and laboratory space located on a 6.3 acre tract of land owned by the Company in Menlo Park, California, an adjacent 32,000 square foot office building owned by the Company, and an adjacent 27,000 square feet of leased warehouse storage space. The Company's primary facility is subject to a variable rate mortgage tied to London Interbank Offering Rate which, as of the period ending January 1, 1999, aggregated $16.2 million in principal amount outstanding.

The Company's Test and Engineering Center occupies 147 acres in Maricopa County, Arizona. The Company leases this land from the state of Arizona under a 30-year lease agreement that expires in January of 2028.

In addition, the Company leases office, warehouse and laboratory space in 23 other separate locations in 14 states as well as in Germany. During fiscal 1998, the Company made a decision to close down its offices is Moscow and Poland.

Leases for these offices, warehouse and laboratory facilities have terms generally ranging between one to ten years. Aggregate lease payments in fiscal 1998 for all leased properties were approximately $2,715,000.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

With the exception of the discussion below regarding the Company's readiness for Year 2000 compliance, the information required by this item is incorporated by reference to the section entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the 1998 Annual Report. An excerpt from the Annual Report to the Stockholders containing this information has been filed as Exhibit 13.1 to this Annual Report on Form 10-K.

YEAR 2000 COMPLIANCE

GENERAL
The Year 2000 (Y2K) issue is the result of certain computer hardware, operating system software and software application programs having been developed using two digits rather than four to define a year. For example, the clock circuit in the hardware may be incapable of holding a date beyond the year 1999; some operating systems may recognize a date using "00" as the year 1900 rather than 2000 and certain applications may have limited date processing capabilities. These problems could result in the failure of major systems or miscalculations, which could have a material adverse affect on companies through business interruption or shutdown, financial loss, damage to reputation, and legal liability to third parties.

STATE OF READINESS

The Company established a Year 2000 Readiness Project Team comprised of senior executives of the Company in the areas of Management Information Systems, Facilities and Operations, and Finance.

14

The Project Team reports to the President and Chief Executive Officer and the Audit Committee of the Board of Directors.

The Project Team developed and manages the Company's Y2K Plan to address the potential impact of Y2K on the Company's operations and business processes. In particular, the Plan identified 8 principal areas that may be impacted by the Y2K issue: Business Systems; Facility Systems; End-User Community; Non- Production Suppliers; Financial Services; Communication Providers; Outsourcing Vendors; and Business Partners/Joint Ventures. With respect to the IT Systems and Non-IT Business Systems, the Y2K Plan consists of two separate but overlapping phases: Phase I - Inventory and Risk Assessment; and Phase II - Remediation.

Phase I - Inventory and Risk Assessment

This Phase requires an inventory and assessment of the Non-IT Business Systems used by the Company including systems with embedded technology, building access systems, and health and safety systems. This Phase also includes inventory and assessment of IT Systems used by the Company which include large information technology systems, desktop hardware and software, and network hardware and software. Each system is evaluated and a priority is assigned as being High, Medium or Low Risk to the Company's business. Systems which are High Risk are those which if uncorrected would cause an interruption or complete failure to conduct the Company's business. Medium Risks are those which would negatively impact the business but complete cessation could be avoided with some inconvenience. Low Risks are those where the risk to business interruption or cessation are remote. High and Medium Risk items will be remediated or replaced, and Low Risk items will be addressed as time and resources permit. Currently, the Company has completed Phase I.

Phase II - Remediation

This Phase includes the replacement or correction of the High and Medium Risk Non-IT Business Systems and IT Systems. A detailed project plan for the remediation has been developed and is currently being implemented. This Phase is approximately 80% complete and the Company anticipates that this Phase will be completed during the third quarter of fiscal 1999.

THIRD PARTY RELATIONSHIPS

The Company's business operations are dependent on third party corporate service vendors, materials suppliers, outsourced operations partners and others. The Company is working with key external parties to identify and attempt to mitigate the potential risks to it of Y2K. The failure of external parties to resolve their own Y2K issues in a timely manner could result in a material adverse financial risk to the Company. As part of its overall Y2K program, the Company is actively communicating with third parties on an ongoing basis to ascertain their state of readiness. Although numerous third parties have indicated to the Company in writing that they are addressing their Y2K issues on a timely basis, the readiness of third parties overall varies widely. Because the Company's Y2K compliance is dependent on the timely Y2K compliance of third parties, there can be no assurances that the Company's efforts alone will resolve all Y2K issues.

COST TO ADDRESS Y2K

The costs of the Y2K program are primarily costs associated with the utilization of existing internal resources and minimal external spending. These costs exclude the costs that could be incurred by

15

the Company if one or more of its significant third party service providers fail to achieve Y2K compliance. The Company is not separately identifying Y2K costs incurred that are the result of utilization of existing internal resources.

To date, the historical and estimated costs of remediation to address the Company's Y2K issues have not been material and have been funded through working capital resources.

RISK FACTORS

Based on current information, the Company believes the Y2K issue will not have a material adverse effect on the Company, its consolidated financial position, results of operations or cash flows. However, there can be no assurance that the Y2K remediation by the Company or third parties will be properly and timely completed, and the failure to do so could have a material adverse effect on the company, its business, results of operations, and its financial condition. In addition, important factors that could cause results to differ materially include, but are not limited to, the ability of the Company to successfully identify systems which have a Y2K issue, the nature and amount of remediation effort required to fix the affected system, and the costs and availability of labor and resources to successfully address the Y2K issues.

CONTINGENCY PLANS

The Company's contingency plans, which will be based in part on the assessment and the magnitude and probability of potential risk, will primarily focus on steps to prevent Y2K failures from occurring, or if they should occur, to detect them quickly, minimize their impact and expedite their repair.

A failure of the services provided by the Company's project and accounting system could result in the loss of customer records which could disrupt the ability to bill customers for a protracted time. The Company plans to prepare electronic backup records of its project and accounting system prior to the year 2000 to allow for data recovery.

Security and fire protection systems failures could leave facilities vulnerable to intrusion and fire. The Company expects to return such systems to normal functioning by turning the power off and then on again ("power off/on"). The Company also plans to have additional security staff on site. Also, certain personal computers interface and control elevators, public access systems and certain telephony systems. In the event such computers cease operating, conducting a power off/on is expected to resume normal functioning. If a power off/on does not resume normal functioning, the Company expects to resolve the problem by resetting the computer to a pre-designated date that precedes the year 2000.

ITEM 7(A) QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company is exposed to some interest rate risk associated with the Company's long-term debt obligation on the Company's headquarters building. Effective February 1, 1999, the Company refinanced its headquarters building under a 10 year, $35.0 million note. The new note consists of a line of credit with a borrowing amount up to $5.0 million and a revolving reducing note up to $30.0 million for a total maximum borrowing amount of $35.0 million. The line of credit is subject to two interest rate options of either the prime rate in effect from time to time, or a fixed rate determined by the bank to be 2.75% above LIBOR, with a floating rate option of one month, two months, three months, six months, nine months or twelve months. The $30.0 million revolving reducing note is also subject to two interest rate options of

16

either prime less 1.5% or the fixed LIBOR plus 1.25% with a floating rate option of one month, two months, three months, six months, nine months, or twelve months.

The company's general policy for selecting among the interest rate options and related terms will be to minimize interest expense. However, given the risk of interest rate fluctuations, the Company cannot be certain that the lowest rate option will always be obtained, therefore, consistently minimizing the Company's interest expense. No sensitivity analysis was performed on the Company's exposure to interest rate fluctuations, however, given the historical low volatility of both the Prime and LIBOR interest rates, the Company believes any exposure would be minimal.

(i) to determine the Fair Market Value of the Common Stock;

(xiv) to allow Optionees to satisfy withholding tax obligations by electing to have the Company withhold from the Shares to be issued upon exercise of an Option that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by an Optionee to have Shares withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem necessary or advisable; and

(xv) to make all other determinations deemed necessary or advisable for administering the Plan.

(c) Effect of Administrator's Decision. The Administrator's decisions, determinations and interpretations shall be final and binding on all Optionees and any other holders of Options.

5. Eligibility. Options may be granted to Service Providers; provided, however, that notwithstanding anything to the contrary contained in the Plan, an Option may only be granted to an Officer as an inducement essential to his or her initial employment with the Company.

4

6. Limitation. Neither the Plan nor any Option shall confer upon an Optionee any right with respect to continuing the Optionee's relationship as a Service Provider with the Company, nor shall they interfere in any way with the Optionee's right or the Company's right to terminate such relationship at any time, with or without cause.

7. Term of Plan. The Plan shall become effective upon its adoption by the Board. It shall continue in effect for ten (10) years, unless sooner terminated under Section 14 of the Plan.

8. Term of Option. The term of each Option shall be stated in the Option Agreement.

9. Option Exercise Price and Consideration.

(a) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option shall be determined by the Administrator.

(b) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator shall fix the period within which the Option may be exercised and shall determine any conditions which must be satisfied before the Option may be exercised.

(c) Form of Consideration. The Administrator shall determine the acceptable form of consideration for exercising an Option, including the method of payment. Such consideration may consist entirely of:

(i) cash;

(ii) check;

(iii) promissory note;

(iv) other Shares which (A) in the case of Shares acquired upon exercise of an option, have been owned by the Optionee for more than six months on the date of surrender, and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised;

(v) consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan;

(vi) a reduction in the amount of any Company liability to the Optionee, including any liability attributable to the Optionee's participation in any Company-sponsored deferred compensation program or arrangement;

(vii) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or

(viii) any combination of the foregoing methods of payment.

5

10. Exercise of Option.

(a) Procedure for Exercise; Rights as a Shareholder. Any Option granted hereunder shall be exercisable according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Option Agreement. An Option may not be exercised for a fraction of a Share.

An Option shall be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Optionee or, if requested by the Optionee, in the name of the Optionee and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 12 of the Plan.

Exercising an Option in any manner shall decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

(b) Termination of Relationship as a Service Provider. If an Optionee ceases to be a Service Provider, other than upon the Optionee's death or Disability, the Optionee may exercise his or her Option, but only within such period of time as is specified in the Option Agreement, and only to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for three (3) months following the Optionee's termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(c) Disability of Optionee. If an Optionee ceases to be a Service Provider as a result of the Optionee's Disability, the Optionee may exercise his or her Option within such period of time as is specified in the Option Agreement, to the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee's termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

6

(d) Death of Optionee. If an Optionee dies while a Service Provider, the Option may be exercised within such period of time as is specified in the Option Agreement (but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant), by the Optionee's estate or by a person who acquires the right to exercise the Option by bequest or inheritance, but only to the extent that the Option is vested on the date of death. In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee's termination. If, at the time of death, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall immediately revert to the Plan. The Option may be exercised by the executor or administrator of the Optionee's estate or, if none, by the person(s) entitled to exercise the Option under the Optionee's will or the laws of descent or distribution. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(e) Buyout Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares, an Option previously granted based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made.

11. Non-Transferability of Options. Unless determined otherwise by the Administrator, an Option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. If the Administrator makes an Option transferable, such Option shall contain such additional terms and conditions as the Administrator deems appropriate.

12. Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset
Sale.

(a) Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per share of Common Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible in shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective date of such proposed transaction. The Administrator in its discretion may provide for an Optionee to have the right to exercise his or her Option until ten (10) days prior to such transaction as to all the Optioned Stock covered thereby, including Shares as to which the Option would not

7

otherwise be exercisable. In addition, the Administrator may provide that any Company repurchase option applicable to any Shares purchased upon exercise of an Option shall lapse as to all such Shares, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously exercised, an Option will terminate immediately prior to the consummation of such proposed action.

(c) Merger or Asset Sale. In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the assets of the Company, each outstanding Option shall be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the Option, the Optionee shall fully vest in and have the right to exercise the Option as to all of the Optioned Stock, including Shares as to which it would not otherwise be vested or exercisable. If an Option becomes fully vested and exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Optionee in writing or electronically that the Option shall be fully vested and exercisable for a period of fifteen (15) days from the date of such notice, and the Option shall terminate upon the expiration of such period. For the purposes of this paragraph, the Option shall be considered assumed if, following the merger or sale of assets, the option or right confers the right to purchase or receive, for each Share of Optioned Stock, immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets by holders of Common Stock for each Share held on the effective date of the transaction (and if holder were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or sale of assets is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option, for each Share of Optioned Stock to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the merger or sale of assets.

13. Date of Grant. The date of grant of an Option shall be, for all purposes, the date on which the Administrator makes the determination granting such Option, or such other later date as is determined by the Administrator. Notice of the determination shall be provided to each Optionee within a reasonable time after the date of such grant.

14. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan.

(b) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan shall impair the rights of any Optionee, unless mutually agreed otherwise between the Optionee and the Administrator, which agreement must be in writing and signed by the Optionee and the Company. Termination of the Plan shall not affect the Administrator's ability to exercise the powers granted to it hereunder with respect to options granted under the Plan prior to the date of such termination.

8

15. Conditions Upon Issuance of Shares.

(a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance.

(b) Investment Representations. As a condition to the exercise of an Option the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

16. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

17. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENT
The statements in this report that are forward-looking are based on current expectations, and actual results may differ materially. These forward-looking statements involve numerous risks and uncertainties that could cause actual results to differ materially, including but not limited to, the possibility that the demand for the Company's services may decline as a result of changes in general and industry specific economic conditions and the effects of competitive services and pricing; one or more current or future claims made against the Company may result in substantial liabilities; and such other risks and uncertainties as are described in reports and other documents filed by the Company from time to time with the Securities and Exchange Commission.

OVERVIEW
The Company, together with its subsidiaries, is a multidisciplinary organization of scientists, physicians, engineers and business consultants performing in- depth scientific research and analysis in over 50 technical disciplines. The Company's services include analysis of product development or product recall, regulatory compliance, discovery of potential problems related to products, people or property and impending litigation.

During fiscal 1997, the Company continued implementing its strategy of growth and diversification through the acquisition of BCS Wireless, Inc. ("BCS") and Exponent Environmental Group, Inc. ("EEG"), formerly named Performance Technologies, Incorporated. BCS, acquired on January 4, 1997, specializes in the design, installation and maintenance of wireless communication networks. BCS is located in the greater Madison, Wisconsin area and has erected communication towers and provided related training and technical services for the telecommunications industry since 1981. EEG, acquired on May 16, 1997, is a scientific and engineering consulting firm specializing in providing scientific solutions for complex environmental problems. BCS and EEG, when combined with Exponent Health Group, Inc. ("EHG"), formerly named Environmental Health Strategies, Inc., which was acquired effective August 1, 1996, are collectively herein referred to as the "Acquisitions."

In addition to acquiring companies, the Company made a strategic decision to sell one of its subsidiaries PLG, Inc. ("PLG"), in the third quarter of fiscal 1997. The Company made the decision to sell PLG based on management's assessment that the services PLG provided were no longer complementary to the Company's core business practice areas. The Company has recorded the results of operations for PLG as discontinued operations in the consolidated state-ments of operations for all years presented.

Fiscal years ended January 1, 1999, January 2, 1998 and January 3, 1997

REVENUES The Company's revenues consist of professional fee services, fees for use of the Company's equipment and facilities as well as third party expenses directly associated with the services performed that are billed to the client. Third party expenses are included in revenue net of the related costs.

During fiscal 1998, revenues increased by $12.0 million or 16.3%. This increase is primarily due to an increase in revenue associated with the Company's environ-mental and health segment, which had a revenue increase of $6.3 million or 52.5% of the total revenue increase. The revenue increase associated with the environmental and health segment was primarily due to the inclusion of four additional months of revenue in fiscal 1998 compared to fiscal 1997 for the Environmental Group. BCS, the Company's wireless communication joint-venture business, contributed $2.5 million of the total $12.0 million increase while the Company's other scientific and engineering segment increased slightly by $3.2 million over fiscal 1997. The revenue increase associated with the Company's other scientific and engineering segment is primarily attributable to an increase in total billable hours in fiscal 1998 associated with an increase of professional staff of approximately 15 employees over fiscal 1997.

Total fiscal 1997 revenues increased by $20.2 million or 37.9% over fiscal 1996. This increase in revenue is partially a result of the Acquisitions, which contributed $13.3 million, or 65.8% of the total revenue increase. The remaining $6.9 million increase is due to a general increase in the Company's other scientific and engineering segment across many technical disciplines. This internal growth was achieved through an increase of billable hours which resulted from an increase in consulting staff in fiscal 1997 of approximately 31 employees, in addition to higher average billable utilization rates due to an increase in demand of the Company's services.

COMPENSATION AND RELATED EXPENSES In fiscal 1998, total compensation and related costs increased by $9.2 million or 19.9% over fiscal 1997. The environmental and health segment accounted for $4.9 million or 53.3% of the total increase, primarily due to the inclusion of four additional months of compensation expense in fiscal 1998 associated with the Environmental Group.

2

BCS contributed $1.1 million of the total $9.2 million compensation increase, an increase associated with a 40% increase of staff over fiscal 1997. The remaining $3.2 million increase is attributable to the Company's other scientific and engineering segment. This increase in compensation expense resulted from an increase in professional and administrative staff of approximately 15 employees in addition to an increase in the average employee salary. As a percentage of revenue, compensation and related expenses increased to 64.5% in fiscal 1998 from 62.6% in fiscal 1997. This increase is primarily a result of lower average professional staff utilization rates in fiscal 1998 compared to fiscal 1997 which resulted from an increase in professional staff occurring at a faster rate than anticipated business growth.

Total fiscal 1997 compensation and related costs increased by $12.5 million or 37.1% over fiscal 1996. Acquisitions accounted for $8.6 million or 68.8% of the total increase. The remaining increase of $3.9 million is generally due to an increase in employee compensation resulting from an 8% increase in the number of employees in fiscal 1997. As a percentage of revenue, total compensation decreased slightly to 62.6% in fiscal 1997 from 63.0% in fiscal 1996.

OTHER OPERATING EXPENSES Other operating expenses increased by $3.2 million or 22.9% over fiscal 1997. The environmental and health segment contributed $1.1 million of the total operating expense increase while BCS accounted for approximately $800,000. The increase in operating expenses associated with the environmental and health segment is again attributable to the addition of four months of operating expense in fiscal 1998 compared to fiscal 1997. The increase in BCS's operating expense is primarily attributable to an increase in cost of goods sold and leased equipment expense directly associated with the overall increase in revenue. Operating expenses for the Company's other scientific and engineering segment increased by $1.3 million or 40.6% of the total operating expense increase. This increase was due to an increase in occupancy costs and depreciation expense associated with the relocation of offices during fiscal 1998. As a percentage of revenue, operating expenses increased to 20.2% in fiscal 1998 from 19.1% in fiscal 1997, an increase directly associated with the relocation and expansion of offices, while revenue growth was not as strong.

In fiscal 1997, other operating expenses increased by $1.6 million or 13.2% over fiscal 1996. This increase is primarily attributed to the Acquisitions, which accounted for $2.1 million of the total operating expense increase in fiscal 1997, while the Company's other scientific and engineering segment had a decrease in other operating expenses of approximately $500,000. The $500,000 decrease in the Company's other scientific and engineering segment operating expenses was due to a decrease in depreciation expense and other computer- related expenses associated with the ongoing cost savings from the conversion to a new, lower cost accounting system which was imple-mented in October 1996. Other operating expenses as a percentage of revenue decreased to 19.1% in fiscal 1997 from 23.2% in fiscal 1996. This decrease was achieved from the cost savings of the Company's new accounting software package while revenues for the Company increased.

GENERAL AND ADMINISTRATIVE EXPENSES General and administrative expenses increased by $1.8 million or 26.4%. This increase is primarily attributable to the Company's other scientific and engineering segment, which accounted for $1.6 million of the total $1.8 million increase. Of the $1.6 million increase, approx-imately $850,000 is due to an increase in bad debt expense of which approximately $280,000 resulted from some unusually large client bankruptcies. Approximately $600,000 is due to an increase in travel, marketing and outside consulting expense associated with the Company's increased marketing efforts. As a percentage of revenue, general and administrative expenses increased to 10.3% in fiscal 1998 from 9.4% in fiscal 1997.

In fiscal 1997, general and administrative expenses increased by $1.4 million or 24.8% over fiscal 1996. Acquisitions accounted for $1.9 million of this increase, while the Company's other scientific and engineering segment had a decrease in general and administrative expenses of approximately $500,000 primarily due to a decrease in bad debt and marketing expense. As a percentage of revenue, general and administrative expenses decreased to 9.4% in fiscal 1997 from 10.5% in fiscal 1996, which is a result of the Company's efforts to maintain overhead expenses as revenues continue to grow.

OTHER INCOME AND EXPENSE Other income and expense consists primarily of interest expense on the Company's mortgage net of interest income earned on corporate investments and rental income derived from the leasing of certain portions of the Company's headquarters building.

Other income and expense, net, increased by $314,000 or 34.4%. This increase is primarily due to a $725,000 decrease in interest expense associated with the Company's IRS settlement and a decrease in mortgage

3

interest of approximately $100,000. This decrease in interest expense was partially offset by a decrease in interest income of approximately $350,000 due to lower average cash and investment balances during fiscal 1998, in addition to a slight decrease in rental income of approximately $138,000 due to a decrease in space subleased to outside companies.

In fiscal 1997, other income and expense increased by $480,000 or 110.6% over fiscal 1996. This increase is principally due to an increase in rental income resulting from both an increase in the amount of square footage leased to outside entities, in addition to an increase in the rent charged per square foot.

INCOME TAXES In fiscal 1998, income taxes as a percentage of income is 25.9%. This lower effective tax rate is primarily due to the Company removing a 100% valuation allowance recorded against the $788,000 deferred tax asset generated from a tax loss resulting from the sale of PLG in September 1997. The decision to remove the valuation allowance was based upon plans management is working on to generate capital gains via a potential sale of one or more of its owned buildings at the Company's headquarters facility. Other options for generating capital gains are also being evaluated. The Company has until fiscal year 2002 to generate sufficient capital gains to utilize the entire $788,000 deferred tax asset.

The Company's income taxes as a percentage of income from continuing operations is 40.5% for fiscal 1997. In fiscal 1996, income taxes as a percentage of income from continuing operations is 17%. This lower effective tax rate is primarily due to the tax benefit from tax-exempt interest earned on the Company's investments in fiscal 1996.

DISCONTINUED OPERATIONS In September 1997, the Company sold its wholly-owned subsidiary, PLG, for approximately $2.0 million. Accordingly, the results of operations for PLG have been shown in the consolidated statements of operations as a loss from discontinued operations, net of taxes, for all fiscal years presented. Additionally, during fiscal 1996, the Company determined that the goodwill associated with the purchase of PLG became impaired and, therefore, wrote off the remaining $1.6 million goodwill balance. This goodwill write-off in addition to goodwill amortization during fiscal 1996 and 1995 has been included in the loss from discontinued operations.

EXTRAORDINARY ITEM In June 1996, the Company committed to refinance its building mortgage. The Company recorded the tax-effected prepayment penalty charge of $443,000 for the refinancing of this note, as an extraordinary item in the statement of operations.

LIQUIDITY AND CAPITAL RESOURCES At January 1, 1999, the Company had $6.1 million in cash and cash equivalents. The Company has financed its business principally through cash flows from operating activities.

Net cash provided by operating activities was $1.2 million in fiscal 1998 compared to $3.8 million in fiscal 1997. This decrease in operating cash flow in fiscal 1998 is primarily due to an increase in accounts receivable associated with the Company's continued revenue growth, in addition to an increase of days of revenue outstanding at the end of fiscal 1998 compared to fiscal 1997. Additionally, cash provided by operating activities decreased over fiscal 1997 because of a decrease in income taxes payable due to earlier payment of fiscal 1998 taxes, in addition to an increase in the net deferred tax asset. This decrease in cash from changes in operating assets and liabilities was partially offset by an increase in net income after adjusted for non-cash items in fiscal 1998 compared to fiscal 1997. The Company has historically and will continue to experience swings in the timing of its collections. Despite the increase in days of revenue outstanding, the general credit quality of the Company's clients remains high due to the majority of the Company's clients being Fortune 500 companies who pose minimal credit risk.

During fiscal 1998, the Company generated approximately $500,000 of cash from investing activities primarily through the sale of short-term investments for a net amount of $6.3 million offset by cash used for capital expenditures of $5.4 million. During fiscal 1997, the Company generated $1.3 million from investing activities again primarily through the sale of short-term investments for a net amount of $13.8 million offset by cash used for acquisitions of approximately $7.8 million and capital expenditures of $4.2 million.

Net cash used in financing activities increased to $4.0 million in fiscal 1998 compared to $1.1 million in fiscal 1997. This increase is primarily due to stock repurchases in fiscal 1998 of $3.4 million.

4

The Company's long-term obligations at January 1, 1999 consisted primarily of the mortgage obligation on the headquarters facility of $16.2 million. Additionally, the Company renewed its $10.0 million line of credit agreement in August 1998. There were no amounts borrowed against the line of credit during fiscal 1998, 1997 or 1996. In February 1999, the Company refinanced both its mortgage and line of credit under one borrowing agreement for a total maximum borrowing amount of $35.0 million. See further discussion under Note 16 of Notes to Consolidated Financial Statements.

Management believes that its existing cash, together with its new credit line and funds generated from operations, will provide adequate cash to fund the Company's anticipated cash needs through at least the next twelve-month period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
EXPONENT, INC. AND SUBSIDIARIES

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION Exponent, Inc. together with its subsidiaries (referred to as the "Company"), is a multidisciplinary organization of scientists, physicians, engineers and business consultants performing in-depth scientific research and analysis in over 50 technical disciplines. The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Exponent Failure Analysis Associates, Inc. ("FaAA"), Exponent Health Group, Inc. ("EHG"), Exponent Environmental Group, Inc. ("EEG"), BCS Wireless, Inc. ("BCS") and PLG, Inc. ("PLG") whose results of operations have been accounted for as a discontinued operation for all fiscal years presented. All significant inter-company transactions and balances have been eliminated in consolidation.

The Company operates on a 52-53 week fiscal calendar year with each year ending on the Friday closest to December 31st. Fiscal periods 1998, 1997 and 1996 will be represented by the fiscal period dates ending January 1, 1999, January 2, 1998 and January 3, 1997, respectively.

REVENUE RECOGNITION The Company derives most of its revenue from professional service activities, generally at the time services are performed. The majority of these activities are provided under a time and materials or fixed-price billing arrangement with revenues consisting of professional fees and expenses and fees for the use of the Company's equipment and facilities in connection with the services provided. On fixed-price contracts, revenue is recognized on the basis of the estimated percentage of completion of services rendered.

The Company reports revenue net of outside direct expenses which consists primarily of subcontractor fees and travel expenses. Outside direct expenses reported against revenue excluding PLG were approximately $13,129,315, $10,755,000 and $6,245,000 in fiscal 1998, 1997 and 1996, respectively.

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

RECLASSIFICATIONS Certain amounts in the accompanying 1996 consolidated financial statements have been reclassified in order to conform with the presentation of the 1998 and 1997 consolidated financial statements.

CASH EQUIVALENTS Cash equivalents consist of highly liquid investments such as money market mutual funds and commercial paper with original maturities of three months or less.

SHORT-TERM INVESTMENTS Short-term investments consist of fixed-income taxable corporate and treasury bonds. The Company's securities are classified as "available-for-sale" and are carried at fair market value, with the unrealized gains and losses reported as a separate component of stockholders' equity as accumulated other comprehensive income.

PROPERTY, EQUIPMENT AND LEASEHOLD IMPROVEMENTS Property, equipment and leasehold improvements are stated at cost less accumulated depreciation or amortization. Depreciation and amortization are computed using the straight- line method. Buildings are depreciated over their estimated useful lives ranging from 30 to 40 years. Equipment is depreciated over its estimated useful life, which generally ranges from two to seven years. Leasehold improvements are amortized over the shorter of their estimated useful lives, generally seven years, or over the term of the related lease.

IMPAIRMENT OF LONG-LIVED ASSETS AND ASSETS TO BE DISPOSED OF The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to future cash flows to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or the fair value less costs to sell.

GOODWILL Goodwill represents the excess of the purchase price over the fair market value of the net assets of various entities acquired by the Company accounted for under the purchase method of accounting. The Company currently amortizes goodwill on a straight-line basis over periods ranging from 7 to 20 years. In January 1997 the Company recorded $485,000 of goodwill and in May 1997, the Company recorded $7.2 million of goodwill arising

11

from the purchase of its two new subsidiaries, BCS and EEG respectively. Additionally, during fiscal 1998, the Company recorded additional goodwill of approximately $393,000 associated with the acquisition of EHG which considered future payments to be paid based upon the attainment of certain revenue and profitability requirements. These future payments have been accounted for as goodwill as they have been treated as an adjustment to the original acquisition purchase price.

The Company periodically evaluates the ongoing profitability of the businesses acquired to determine if there is goodwill impairment. In accordance with the Company's policy in evaluating the impairment of a long-lived asset, the Company made the decision to writeoff the remaining goodwill related to the purchase of its subsidiary, PLG, during the fourth quarter of 1996. The total amount charged to income was $1.6 million.

INCOME TAXES Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis and the financial reporting basis of assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates and laws in effect when the differences are expected to reverse. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not, that some portion or all of the deferred tax assets will not be realized.

FAIR VALUE OF FINANCIAL INSTRUMENTS Financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable and long-term debt. The carrying amount of the Company's cash and cash equivalents, accounts receivable, accounts payable and debt obligations approximate their fair values which for debt is based upon current rates available to the Company.

STOCK-BASED COMPENSATION The Company uses the intrinsic value method to account for all of its employee stock-based compensation plans.

NET INCOME (LOSS) PER SHARE Basic per share amounts are computed using the weighted-average number of common shares outstanding during the period. Dilutive per share amounts are computed using the weighted-average number of common shares and potential common shares outstanding, using the treasury stock method, even when antidilutive, if their effect would be dilutive on the per share amount of income from continuing operations.

The following schedule reconciles both the numerator and denominator of the Company's calculation for basic and dilutive net income (loss) per share:

Common stock options to purchase 126,761, 609,201 and 584,476 shares were excluded from the diluted per share calculation for the fiscal years ended January 1, 1999, January 2, 1998 and January 3, 1997, respectively, due to their antidilutive effect.

RECENT ACCOUNTING PRONOUNCEMENTS Effective for the fiscal year ending January 1, 1999, the Company adopted SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information" ("SFAS No. 131"). SFAS No. 131 establishes standards for reporting information about operating segments in annual financial statements and requires selected information about operating segments in interim financial reports issued to stockholders. It also establishes standards for related disclosure about products and services and geographic areas. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker.

Other long-term obligations consist primarily of deferred compensation and a note with a third party financing company for the financing of the Company's corporate insurance.

The Company's existing mortgage, which had an original principal balance of $18.7 million, is secured by the Company's headquarters building and has a 15- year life with equal principal payments of $623,333 due semi-annually on February 1 and August 1. The note bears a floating rate of interest tied to LIBOR and is subject to adjustment every month. The rate on this note was 6.75% as of January 1, 1999.

In August 1998, the Company renewed its $10.0 million unsecured line of credit agreement. This agreement expires in July 1999. There were no borrowings against the line of credit in fiscal 1998 or fiscal 1997. The mortgage note and line of credit contain restrictive covenants.

Principal payments due on long-term obligations are $1,709,000, $1,825,000, $1,537,000, $1,329,000 and $1,287,000 in fiscal 1999 through fiscal 2003, respectively, and $10,166,000 thereafter.

In February 1999, the Company refinanced both its mortgage and line of credit under one borrowing agreement. See further discussion under Note 16 of Notes to Consolidated Financial Statements.

The net change in the total valuation allowance for the fiscal year 1998 was a decrease of $788,000. Management believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize the net deferred assets.

The Company has a capital loss carryforward of $2,071,000 for federal and state tax purposes that will expire in fiscal years 2000 through 2002.

EMPLOYEE STOCK PURCHASE PLAN The Company has authorized 400,000 shares of common stock for issuance under the 1992 Employee Stock Purchase Plan (the "Purchase Plan"). Qualified employees may elect to have a certain percentage (not to exceed 15%) of their salary withheld for purchase of stock pursuant to this plan. On July 23, 1997, the Board of Directors amended the Purchase Plan to reduce the discount price at which employees may purchase the Company shares from 90% to 85% of the lower of the fair market value of the common stock at the beginning or ending of a three month offering period. As of January 1, 1999, 348,792 shares have been sold under the plan. Weighted-average purchase prices for shares sold under the plan in fiscal 1998, 1997 and 1996 were $5.96, $5.35 and $5.13, respectively.

RESTRICTED STOCK PLAN In March 1991, the Board of Directors approved a restricted stock plan for key employees and directors. Up to an aggregate of 200,000 common shares had been reserved for grant under the plan. This plan was terminated as of October 24, 1996. Prior to termination, 100,000 shares were granted of which 97,500 shares have vested as of January 1, 1999.

STOCK OPTION PLANS The Company has an incentive stock option plan, which covers up to an aggregate of 2,000,000 shares of common stock. In October 1998, the Board approved a new non-statutory stock option plan, which covers up to an aggregate of 300,000 shares of common stock. Both plans provide for the grant of either incentive stock options, exercisable at a price equal to the fair market value of the shares at the date of grant, or non-qualified options, exercisable at a price not less than 85% of the fair market value of the shares at the date of grant. Options are granted for terms of up to ten years and generally vest ratably over a four-year period from the grant date. In addition, the company has a stock option plan for one officer covering up to 119,000 shares of common stock, all of which have been granted and 29,760 have been exercised as of January 1, 1999. All three stock option plans are collectively referred to as the "Plan."

PRO FORMA FAIR VALUE INFORMATION The Company uses the intrinsic value method in accounting for its Employee Purchase Plan and Stock Option Plan, collectively called "Options." As the Options are generally granted at exercise prices equal to the fair value of the Company's common stock on the date of the grant, no compensation expense has been recognized in the financial statements. SFAS No. 123, "Accounting for Stock-Based Compensation," ("SFAS No. 123") requires the Company to disclose pro forma information regarding net income and earnings per share as if the Company had accounted for its Options under the fair value method. Under the fair value method, compensation expense is calculated for options granted using a defined valuation technique. The Company uses the Black- Scholes option pricing model to calculate the fair value of its Options. In calculating the fair value of an option at the date of grant, the Black-Scholes option pricing model requires the input of highly subjective assumptions. The Company used the following weighted-average assumptions for 1998, 1997 and 1996:

                         Employee Stock Purchase Plan     Stock Option Plan
                         1998       1997       1996       1998    1997    1996
------------------------------------------------------------------------------

Risk-free
  interest rate         4.85%       5.61%      5.60%       4.3%    6.2%    6.8%
Volatility              4.67        0.74       0.79       0.87    0.76    0.72

Using the above assumptions, the weighted-average fair value of options granted during 1998, 1997 and 1996 was $5.06, $4.82 and $4.05, respectively.

Had the Company determined compensation cost based on the estimated fair value at the grant date for its Options under SFAS No. 123, the Company's net income from continuing operations would have been adjusted to the pro forma amounts indicated below:

NOTE 7: PENSION PLAN

The Company's subsidiaries Exponent Failure Analysis Associates, Inc. and Exponent Health Group, Inc. have a defined contribution retirement plan covering all salaried employees of at least 21 years of age. Contributions made to this plan were $1,922,000, $1,965,000 and $1,745,000 in fiscal 1998, 1997 and 1996 respectively.

Effective January 1, 1999, the Company terminated its existing defined contribution retirement plan and

15

modified its existing 401K plan whereby the Company will contribute to each eligible employee's 401K account, 7% of the employee's base salary plus overtime, regardless of the amount contributed by the employee. The employee does not need to make a contribution to the plan to be eligible for the Company's 7% contribution. To be eligible under the plan, an employee must be at least 21 years of age and be either a full-time or part-time salaried employee. The 7% Company contribution will vest 20% a year for employees hired after January 1, 1999 and immediately for employees hired as of December 31, 1998. The Company's subsidiaries, Exponent Failure Analysis Associates, Inc., Exponent Health Group, Inc. and Exponent Environmental Group, Inc. are covered under the newly modified 401K plan.

NOTE 8: COMMITMENTS AND CONTINGENCIES

Total rent and equipment lease expense in 1998, 1997 and 1996 was $3,115,000, $2,548,000 and $2,369,000, respectively.

From time to time, the Company may be subject to other claims that arise in the ordinary course of business. In the opinion of management, all such matters involve amounts which would not have a material adverse effect on the Company's consolidated financial position if unfavorably resolved. There are currently no such matters.

NOTE 10: CLIENT AND INDUSTRY CREDIT RISK

The Company serves clients in various segments of the economy. During 1998, 1997 and 1996, the Company provided services, representing approximately 27%, 29% and 38%, respectively, of revenues to clients and to organizations and insurers acting on behalf of clients in the transportation industry.

Revenues of approximately $10,076,000, $5,246,000 and $6,886,000 in fiscal 1998, 1997 and 1996, respectively, were earned on engagements for one client or for organizations insuring or providing services to such client. As of January 1, 1999 and January 2, 1998, accounts receivable included $3,640,000 and $1,912,000, respectively, related to this client.

The majority of the Company's clients are Fortune 500 companies who pose minimal credit risk. The Company maintains reserves for potential credit losses, but historically has not experienced any significant losses related to individual customers or groups of customers in any particular industry.

NOTE 11: ACQUISITIONS

As part of the Company's strategic objective to grow revenues, during fiscal year 1997, the Company acquired two new companies, BCS Wireless, Inc. ("BCS") and Exponent Environmental Group, Inc. ("EEG"), formerly named Performance Technologies, Incorporated. BCS, acquired on January 4, 1997, is a company that specializes in the design, installation and maintenance of wireless communication networks. They are located in the greater Madison, Wisconsin area and have erected communication towers and provided related training and technical services for the telecommunications industry since 1981. The Company acquired all of the stock of BCS for $375,000 in cash. The Company recorded $485,000 in goodwill, which is being amortized over seven years using the straight-line method. EEG, acquired on May 16, 1997, is a scientific and engineering consulting firm specializing in scientific solutions for complex environmental problems. The Company acquired all of the stock of EEG for approximately $7.5 million in cash and 480,002 shares of stock with an approximate value of $2.4 million. The Company recorded approximately $7.2 million of goodwill, which is being amortized over twenty years using the straight-line method.

On August 1, 1996, the Company acquired Exponent Health Group, Inc. ("EHG"), formerly named Environmental Health Strategies, Inc. EHG provides epidemiological services in the areas of occupational and environmental health, pharmaceutical and

16

medical devices and health-related consumer product safety. The Company acquired all of the stock of EHG for a combination of $250,000 in cash and 283,742 shares of stock for a total purchase price of $2.1 million. The Company recorded approximately $2.0 million of goodwill, which is being amortized over seven years using the straight-line method. Under the original acquisition agreement, future contingent payments of either cash or stock were considered, based upon the attainment of certain revenue and profitability requirements as defined per the terms of the agreement. Contingent payments were to be made at the end of each fiscal year through fiscal 2001 if the revenue and profitability requirements were attained. In February 1998, the Company made the first contingent payment of $143,000 for EHG's financial performance through fiscal 1997. In September 1998, the original acquisition agreement was amended whereby the Company's obligation for any future contingent payments was terminated in exchange for a final payment of $250,000. Both payments were recorded against goodwill as a purchase price adjustment.

All acquisitions have been accounted for as purchases and, accordingly, the purchase price was allocated to the net assets acquired based on the estimated fair market value at the date of the acquisition. The results of operations from the date of the acquisitions have been included in the Company's consolidated financial statements. Pro forma disclosures giving effect to the acquisitions of both BCS and EHG do not differ materially from the Company's historical results. Results from continuing operations for the fiscal years ending January 2, 1998 and January 3, 1997 assuming the Company and EEG were combined at the beginning of the fiscal year would have been as follows:

NOTE 12: DISCONTINUED OPERATIONS

Effective September 18, 1997 the Company sold all of the outstanding shares of stock of its wholly-owned subsidiary, PLG, for a total purchase price of approx- imately $2.0 million which includes a premium of $600,000 over the net book value. The Company made the decision to sell PLG based on management's assessment that the services PLG provided, which included consulting services primarily to the nuclear industry, were no longer complementary to the Company's core business practice areas.

The Company received an unsecured subordinated promissory note as consideration of the $2.0 million purchase price. The note has an 18-month maturity date and bears interest at 10%. Six quarterly principal payments of approximately $170,000 plus accrued interest started December 18, 1997 with the final quarterly payment plus the remaining principal and any unpaid accrued interest due on March 18, 1999. To date, all principal quarterly payments that have come due have been paid.

Certain expenses related to the sale of PLG and a reserve against the note receivable offset the $600,000 gain on disposal, therefore, no gain on the sale was recorded.

The Company has recorded the results of operations for PLG as a discontinued operation in the consolidated financial statements for all fiscal years presented.

NOTE 16: SUBSEQUENT EVENT (UNAUDITED)

Effective February 1, 1999, the Company refinanced its 15-year life mortgage note on the Company's headquarters building. The old note, which had an outstanding principal balance of $16.2 million at the time of the refinancing, had a floating rate of interest that was tied to LIBOR and was subject to adjustment every month. Principal payments of $623,333 were due semi-annually on February 1 and August 1 with the final principal payment and all accrued interest due and payable on August 1, 2011.

The new note consists of a line of credit with a borrowing amount up to $5.0 million and a revolving reducing note up to $30.0 million for a total maximum borrowing amount of $35.0 million. The $5.0 million line of credit is subject to two interest rate options of either the prime rate in effect from time to time, or a fixed rate determined by the bank to be 2.75% above LIBOR, with a floating rate option of one month, two months, three months, six months, nine months or twelve months. The line of credit has a one-year term maturing February 1, 2000. The $30.0 million revolving reducing note is also subject to two interest rate options of either prime less 1.5% or the fixed LIBOR plus 1.25% with a floating rate option of one month, two months, three months, six months, nine months or twelve months. This note has a ten-year term maturing February 1, 2009. Interest will be paid on a monthly basis. Principal amounts subject to the prime interest rate may be repaid at any time without penalty. Principal amounts subject to the fixed LIBOR rate may also be repaid at any time but are subject to a prepayment penalty if paid before the fixed-rate term or additional interest if paid after the fixed-rate term. Additionally, the revolving reducing note is subject to annual principal payments based on a 15-year amortization of the initial commitment amount using an interest rate of 3-month LIBOR plus 1.25% in effect on the date of the note.

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.
