      change management, bill of materials management and enterprise integration
      to optimize product development.

      The Company has generated continued losses from operations which has
      reduced its cash balances. At September 30, 2002, the Company had cash and
      cash equivalent balances totaling $2,301,000 and working capital of
      $552,000, each of which represent significantly lower liquidity than in
      the prior year. The Company intends to continue to take appropriate action
      to manage its expenses commensurate with the level of sales expected.
      Among other things, these actions may include a restructuring of its
      operations. Management believes that cash and cash equivalent balances at
      September 30, 2002 are sufficient, combined with management's intent and
      ability to reduce expenditures, to meet its operating and capital
      expenditure requirements and maintain positive liquidity at least through
      March 31, 2003.

      The Company is currently in discussions with several parties regarding the
      possible acquisition of the Company. There can be no assurance that such a
      transaction will be concluded.

2.    Summary of Significant Accounting Policies

      Basis of Presentation

      As permitted by the rules of the Securities and Exchange Commission
      applicable to Quarterly Reports on Form 10-Q, these notes are condensed
      and do not contain all disclosures required by generally accepted
      accounting principles. Reference should be made to the consolidated
      financial statements and related notes included in the Company's Annual
      Report on Form 10-K for the fiscal year ended March 31, 2002. In the
      opinion of the management of the Company, the accompanying consolidated
      unaudited financial statements contain all adjustments (consisting of only
      normal, recurring adjustments) necessary to present fairly the Company's
      financial position at September 30, 2002, and the results of its
      operations for the three and six months ended September 30, 2002 and 2001,
      and statements of cash flows for the six months ended September 30, 2002
      and 2001. The results for the three and six month periods ended September
      30, 2002 are not necessarily indicative of the results to be expected for
      the full fiscal year.

      Risks and Uncertainties

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

                   Notes to Consolidated Financial Statements

3.    Basic and Diluted Earnings Per Share

      The Company's basic net loss per common share is computed by dividing net
      loss by the weighted average number of shares of common stock outstanding.
      Potential common shares include shares issuable upon the exercise of stock
      options or warrants, net of shares assumed to have been purchased by the
      Company with the related proceeds. Potential common shares, which
      consisted only of stock options, were antidilutive for the three and six
      month periods ended September 30, 2002 and 2001 and therefore the diluted
      net loss per common share was the same as basic net loss per common share
      for those periods.

      Options to purchase weighted average shares of the Company's common stock
      of approximately 414,000 and 477,000 were outstanding for the periods
      ended September 30, 2002 and 2001, respectively, at weighted average
      prices of $4.45 and $4.77, respectively, but were not included in the
      computation of diluted earnings per share because they were antidilutive.

4.    Income Taxes

      At March 31, 2002, the Company had available net operating loss
      carryforwards of approximately $39,909,000 which it may use to offset
      future federal taxable income. The net operating loss carryforwards, if
      not utilized, will begin to expire in 2008 for federal purposes and 2003
      for state tax purposes. The Company also had available research and
      development credits of $1,313,000 and $1,054,000 for federal and state
      purposes, respectively. The research and development credits, if not
      utilized, will expire from 2008 through 2017. Due to the uncertainty of
      the realization of deferred tax assets, a full valuation allowance was
      recorded to reduce the deferred tax assets to zero.

      During the first quarter of fiscal 2003, the Company believes that an
      ownership change, as defined in Section 382 of the Internal Revenue Code,
      occurred. As a result of this ownership change, the Internal Revenue Code
      substantially limits the amount of the loss and credit carryforwards that
      can be utilized to offset future taxable income. Management believes that
      the limitation, when combined with the Company's history of losses, is at
      a sufficiently low level, such that it is unlikely that the Company will
      be able to utilize any of the loss or credit carryforwards prior to
      expiration. Accordingly, the Company has written down the deferred tax
      assets associated with the loss and credit carryforwards, and the related
      valuation allowance, to zero. Since the assets had a full valuation
      allowance, there was no impact on the Company's financial position,
      results of operations or cash flows in the first quarter of fiscal 2003 as
      a result of the ownership change.

5.    Recent Accounting Pronouncements

      In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB
      Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and
      Technical Corrections." SFAS No. 145 rescinds SFAS No. 4, "Reporting Gains
      and Losses from Extinguishment of Debt," and an amendment of that
      Statement, SFAS No. 64, "Extinguishment of Debt Made to Satisfy
      Sinking-Fund Requirements," and SFAS No. 44, "Accounting for Intangible
      Assets of Motor Carriers." SFAS No. 145 also amends SFAS No. 13,
      "Accounting for Leases," to eliminate an

      inconsistency between the required accounting for sale-leaseback
      transactions and the required accounting for certain lease modifications
      that have the same economic effects as a sale-leaseback transaction. SFAS
      No. 145 also amends other existing authoritative pronouncements to make
      various technical corrections, clarify meanings, or describe their
      applicability under changed conditions. The provisions of SFAS No. 145
      related to the rescission of SFAS No. 4 are effective for fiscal years
      beginning after May 15, 2002. The provisions of SFAS No. 145 related to
      SFAS No. 13 are effective for transactions occurring after May 15, 2002.
      All other provisions of SFAS No. 145 are effective for financial
      statements issued on our after May 15, 2002. The Company does not expect
      that the provisions of SFAS No. 145 will have a material impact on its
      consolidated financial position, its consolidated results of operations or
      its consolidated cash flows.

      In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs
      Associated with Exit and Disposal Activities". This statement revises the
      accounting for exit and disposal activities under EITF Issue 94-3,
      "Liability Recognition for Certain Employee Termination Benefits and Other
      Costs to Exit an Activity." The provisions of SFAS No. 146 are effective
      prospectively for exit or disposal activities initiated after December 31,
      2002. The Company does not expect that the provisions of SFAS No. 146 will
      have a material impact on its consolidated financial position, its
      consolidated results of operations or its consolidated cash flows.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

RESULTS OF OPERATIONS

Revenue. The Company's revenue consists of license fees for its WTC
ProductCenter family of software products, and fees for professional services
and software maintenance.

Revenue for the second quarter of fiscal 2003 decreased 17% to $1,556,000 from
$1,870,000 compared with the same period of fiscal 2002. This decrease resulted
primarily from a decrease in new customer software license orders and a decrease
in maintenance orders from current customers due to the continued delay in major
purchasing decisions by several of our current customers and major prospects.
Revenue for the six month period ended September 30, 2002 decreased 10% to
$3,256,000 from $3,631,000 in the comparable period of fiscal 2002.

Software license revenue for the three month period ended September 30, 2002
decreased 20% to $267,000 from $332,000 in the comparable period of fiscal 2002.
This decrease resulted primarily from a decrease in new customer orders due to
the delay of purchasing decisions by several of our major prospects. Software
license revenue for the six month period ended September 30, 2002 increased 12%
to $693,000 from $621,000 in the comparable period of fiscal 2002. This increase
resulted primarily from an increase in new customer orders in the first fiscal
quarter of fiscal 2003 when compared to the same period of fiscal 2002.

Maintenance and services revenue for the three and six month periods ended
September 30, 2002 decreased 16% and 15%, respectively, to $1,289,000 and
2,563,000, respectively, from $1,538,000 and 3,010,000, respectively, in the
comparable periods of fiscal 2002. These decreases resulted from certain current
customers delaying major purchasing decisions, including decisions to renew
maintenance agreements on a timely basis. As a result of these delays, the
Company anticipates that fiscal 2003 quarterly maintenance revenue will be lower
than the quarterly maintenance revenue from the previous year.

Cost of Revenue and Gross Profit. The Company's cost of software license revenue
consists primarily of third party royalties payable upon the license of products
for which another party is entitled to receive compensation, as well as costs
associated with media, packaging, documentation and delivery of the Company's
products. Gross profit associated with software license revenue for the second
quarter of fiscal 2003 increased to $265,000 or 99% of software license revenue
from $257,000 or 77% of software license revenue in the second quarter of fiscal
2002. This increase in gross profit is due primarily to lower employee related
expenses and lower third party royalties, partially offset by lower software
license revenue. For the six months ended September 30, 2002, gross profit from
software license revenue increased to $662,000 or 96% of software license
revenue from $476,000 or 77% for the same period of fiscal 2002. This increase
in gross profit is due primarily to higher software license revenue and lower
employee related expenses in fiscal 2003.

Cost of maintenance and services revenue consists primarily of personnel and
related costs for the Company's customer support and professional services
organizations. The Company's gross profit from maintenance and services revenue
increased to $788,000 or 61% of maintenance and services revenue in the second
quarter of fiscal 2003 from $723,000 or 47% of maintenance and service revenue
in the second quarter of fiscal 2002. For the six months ended September 30,
2002 gross profit from maintenance and services revenue increased to $1,436,000
or 56% from

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

$1,172,000 or 39% of the associated revenue in the comparable period of fiscal
2002. These increases in gross profit are due primarily to lower employee
related expenses as well as a favorable adjustment to prior third party
royalties which occurred in the second fiscal quarter of 2003, partially offset
by a decrease in maintenance revenue.

Selling and Marketing. Selling and marketing expenses decreased 43% and 40% for
the three and six month periods ended September 30, 2002 to $419,000 and
$894,000, respectively, from $732,000 and $1,494,000, respectively, for the same
periods of fiscal 2002. These decreases resulted primarily from a decrease in
headcount and related expenses in the sales organization and to a lesser extent,
reduced marketing related activities. As a result of these decreases, selling
and marketing expenses as a percentage of revenue decreased to 27% and 27% in
the three and six month periods of fiscal 2003 from 39% and 41% in the same
periods of fiscal 2002.

Research and Development. Research and development expenses decreased 17% and
23% for the three and six month periods ended September 30, 2002 to $764,000 and
$1,500,000, respectively, from $922,000 and $1,939,000, respectively, for the
same periods of fiscal 2002. These decreases resulted primarily from lower
headcount and related expenses in the development organization. As a result of
these decreases, research and development expenses as a percentage of revenue
decreased to 49% and 46% in the three and six month periods of fiscal 2003 from
49% and 53% in the same periods of fiscal 2002.

General and Administrative. General and administrative expenses decreased 13%
and 12% for the three and six month periods ended September 30, 2002 to $299,000
and $697,000, respectively, from $343,000 and $794,000, respectively, for the
same periods of fiscal 2002. This decrease resulted primarily from lower
employee related expenses, partially offset by an increase in professional
advisor costs. General and administrative expenses as a percentage of revenue
were 19% and 21% for the three and six month periods of fiscal 2003, relatively
consistent with the comparable periods in fiscal 2002.

Interest Income. Interest income consists primarily of interest earned on cash
and cash equivalents. Interest income for the three and six month periods ended
September 30, 2002 decreased $21,000 or 72% and $76,000 or 84%, respectively,
from the same periods of fiscal 2002. These decreases are primarily the result
of lower cash and cash equivalent balances during fiscal 2003.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents at September 30, 2002 decreased $960,000 to $2,301,000
from $3,261,000 at March 31, 2002. This decrease resulted from cash used for
operating activities during the six month period ended September 30, 2002.
Working capital decreased $708,000 to $552,000 at September 30, 2002 from
$1,260,000 at fiscal 2002 year end.

The Board of Directors has authorized the repurchase of 437,500 shares of the
Company's outstanding common stock. The Company did not repurchase any shares of
its common stock during the six month period ended September 30, 2002. At
September 30, 2002, the Company had repurchased approximately 333,000 shares of
the 437,500 shares authorized by the Board of Directors.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

The Company has generated continued losses from operations which has reduced its
cash balances. At September 30, 2002, the Company had cash and cash equivalent
balances totaling $2,301,000 and working capital of $552,000, each of which
represent significantly lower liquidity than in the prior year. The Company
intends to continue to take appropriate action to manage its expenses
commensurate with the level of sales expected. Among other things, these actions
may include a restructuring of its operations. Management believes that cash and
cash equivalent balances at September 30, 2002 are sufficient, combined with
management's intent and ability to reduce expenditures, to meet its operating
and capital expenditure requirements and maintain positive liquidity at least
through March 31, 2003.

To date, neither foreign currency exposure nor inflation has had a material
impact on the Company's financial results.

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

The Company does not provide forecasts of its future financial performance.
However, from time-to-time information provided by the Company or statements
made by its employees may contain "forward-looking" information that involves
risks and uncertainties. In particular, statements contained in filings with the
Securities and Exchange Commission (including this Form 10-Q), press releases
and oral statements which are not historical facts constitute forward-looking
statements and are made under the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995. The Company's actual results of
operations and financial condition have varied and may in the future vary
significantly from those stated in any forward-looking statements and there can
be no assurance that the results set forth in those statements will be achieved.
Factors that may cause such differences include, but are not limited to, the
factors discussed below. Each of these factors, and others, are discussed from
time to time in the Company's filings with the Securities and Exchange
Commission, including the Company's Annual Report on Form 10-K for the fiscal
year ended March 31, 2002 filed in May 2002.

On June 3, 2002, the Company received notice from the Nasdaq Listing
Qualifications Staff that the Company is in violation of certain of the minimum
maintenance standards for continued listing of its common stock on The Nasdaq
SmallCap Market. The Company has appealed the Staff's determination and is
currently awaiting a final decision by the Nasdaq Qualifications Hearing Panel.
There can be no assurance that the Panel will grant the Company's request for
continued listing on The Nasdaq SmallCap Market. If the Panel does not grant the
Company's request, then the Company's securities will be delisted from the
Nasdaq Small Cap Market, but will be eligible to be traded on the
Over-the-Counter Bulletin Board (OTCBB). Delisting of the common stock could
have an adverse effect on the market price of, and the efficiency of the trading
market for, the Company's common stock. Also, if in the future the Company
determines that it needs to seek additional equity capital, it could have an
adverse effect on its ability to raise capital in the public equity markets.

The Company is currently in discussions with several parties regarding the
possible acquisition of the Company. There can be no assurance that such a
transaction will be concluded.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

The Company's future results are subject to substantial risks and uncertainties.
Because the Company derives a substantial portion of its revenue from software
license fees, the Company's quarterly and annual operating results are sensitive
to the size, timing and shipment of individual orders, customer order deferrals
in anticipation of new products or the lengthening of the sales cycle either
generally or with respect to individual customers. In addition, the Company's
growth is dependent on achieving broader market acceptance of its products, the
growth of the product data management market and the ability of the Company to
introduce enhancements and additional integrations to its products in a timely
manner to meet the evolving needs of its customers. The Company also relies on
certain intellectual property protections to preserve its intellectual property
rights. Any invalidation of the Company's intellectual property rights or
lengthy and expensive defense of those rights could have a material adverse
effect on the Company. The segment of the software industry in which the Company
is engaged is extremely competitive. Certain current and potential competitors
of the Company are more established and benefit from greater market recognition
and have substantially greater financial, development and marketing resources
than the Company.

The Company's quarterly and annual operating results are impacted by a variety
of factors that could materially adversely affect revenues and profitability,
including the timing and shipment of enhancements to the Company's products and
changes or anticipated changes in economic conditions. Because the Company's
operating expenses are relatively fixed, an unanticipated shortfall in revenue
in a quarter may have an adverse impact on the Company's results of operations
for that quarter. Actions to manage the Company's expenses commensurate with the
level of sales expected may include a restructuring of its operations. As a
result of the foregoing and other factors, the Company may experience material
fluctuations in future operating results on a quarterly or annual basis which
could materially and adversely affect its business, financial condition and
stock price.

                                  CERTIFICATION

I, Patrick H. Kareiva, Chief Executive Officer and Chief Financial Officer of
Workgroup Technology Corporation, certify that:

      1.    I have reviewed this quarterly report on Form 10-Q of Workgroup
            Technology Corporation;

      2.    Based on my knowledge, this quarterly report does not contain any
            untrue statement of a material fact or omit to state a material fact
            necessary in order to make the statements made, in light of the
            circumstances under which such statements were made, not misleading
            with respect to the period covered by this quarterly report;

      3.    Based on my knowledge, the financial statements, and other financial
            information included in this quarterly report, fairly present in all
            material respects the financial condition, results of operations and
            cash flows of the registrant as of, and for, the periods presented
            in this quarterly report;

      4.    I am responsible for establishing and maintaining disclosure
            controls and procedures (as defined in Exchange Act Rules 13a-14 and
            15d-14) for the registrant and I have;

            a.    designed such disclosure controls and procedures to ensure
                  that material information relating to the registrant,
                  including its consolidated subsidiaries, is made known to me
                  by others within those entities, particularly during the
                  period in which this quarterly report is being prepared;

            b.    evaluated the effectiveness of the registrant's disclosure
                  controls and procedures as of a date within 90 days prior to
                  the filing date of this quarterly report (the "Evaluation
                  Date"); and

            c.    presented in this quarterly report my conclusions about the
                  effectiveness of the disclosure controls and procedures based
                  on the required evaluation as of the Evaluation Date;

      5.    I have disclosed, based on my most recent evaluation, to the
            registrant's auditors and to the audit committee of the registrant's
            board of directors (or persons performing the equivalent function):

            a.    all significant deficiencies in the design or operation of
                  internal controls which could adversely affect the
                  registrant's ability to record, process, summarize and report
                  financial data and have identified for the registrant's
                  auditors any material weaknesses in internal controls; and

            b.    any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the
                  registrant's internal controls; and






                                       15

                                  CERTIFICATION

      6.    I have indicated in this quarterly report whether or not there were
            significant changes in internal controls or in other factors that
            could significantly affect internal controls subsequent to the date
            of my most recent evaluation, including any corrective actions with
            regard to significant deficiencies and material weaknesses.
