                            CALCULATION OF FILING FEE

Transaction Valuation:  $3,753,872.*              Amount of Filing Fee:  $346.**

* For purposes of calculating the filing fee only. The calculation of the
transaction valuation assumes the purchase of 1,841,121 outstanding shares of
Common Stock, par value $.01 per share, of Workgroup Technology Corporation at a
purchase price of $2.00 per share, net to the seller in cash, without interest.
The transaction valuation also includes the offer price of $2.00 less $1.26,
which is the average exercise price per share for those options with an exercise
price of less than the offer price multiplied by 96,797, the estimated number of
options with an exercise price less than the offer price.

** The amount of the filing fee calculated in accordance with Rule 0-11(d) of
the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory No. 6
issued by the Securities and Exchange Commission on October 18, 2002, equals
0.0092% of the value of the transaction.

                                                                    Page 2 of 10

(1) Beneficial ownership of the shares of common stock is being reported
hereunder because the reporting person may be deemed to have beneficial
ownership of such shares as a result of the Merger Agreement and Stockholders
Agreement described in Item 4 of the Schedule TO (as defined below). For
purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended,
such beneficial ownership is expressly disclaimed, except to the extent of its
respective pecuniary interest therein, if any, or as otherwise described in this
Schedule 13D.

(2) Reflects the exercise of the Purchase Option described in Item 4 of the
Schedule TO.

(3) The calculation of the foregoing percentage is based upon the number of
shares of common stock of Workgroup Technology Corporation outstanding as of
December 19, 2002.

                                                                    Page 7 of 10

         This Amendment No.1 (this "Amendment") amends and supplements the
Tender Offer Statement on Schedule TO (this "Schedule TO"), filed initially with
the Securities and Exchange Commission on November 20, 2002 by of SofTech, Inc.,
a Massachusetts corporation ("SofTech"), SofTech Acquisition Corp.
("Purchaser"), a Delaware corporation and a wholly owned subsidiary of SofTech,
Greenleaf Capital, Inc. and William D. Johnston, each affiliates of SofTech
(collectively, the "Reporting Persons"), relating to the tender offer by the
Purchaser to purchase all of the outstanding shares of common stock, par value
$.01 per share (the "Shares"), of Workgroup Technology Corporation, a Delaware
corporation (the "Issuer"), that are not owned by the Purchaser or SofTech at a
purchase price of $2.00 per share, net to the seller in cash, without interest,
upon the terms and conditions set forth in the Offer to Purchase dated November
20, 2002 (the "Offer to Purchase") and in the related Letter of Transmittal (the
"Letter of Transmittal" and which, collectively with the Offer to Purchase, as
each may be amended or supplemented from time to time, constitutes the "Offer),
which were annexed to and filed with the Schedule TO as Exhibits (a)(1)(A) and
(a)(1)(B), respectively.

         This Amendment also amends and supplements and constitutes an amendment
to the Schedule 13D/A filed by the Reporting Persons with the Securities and
Exchange Commission on November 15, 2002 (the "Schedule 13D"). The information
contained herein and in the Schedule TO is incorporated by reference for
purposes of the Schedule 13D.

ITEM 8. INTEREST IN SECURITIES OF THE SUBJECT COMPANY.

ITEM 11. ADDITIONAL INFORMATION

         Items 8 and 11 of the Schedule TO are hereby amended and supplemented
to add the following:

         "The initial offering period for the Offer expired at 12:00 midnight,
Boston, Massachusetts time, on Wednesday, December 18, 2002. Upon the expiration
of the initial offering period the Depositary notified SofTech and the Purchaser
that approximately 1,506,576 Shares were validly tendered and not properly
withdrawn as of the expiration of the initial offering period (including
approximately 3,055 Shares tendered by Notice of Guaranteed Delivery). The
Purchaser accepted for payment and purchase all such validly tendered Shares.
This number of Shares, together with 129,501 Shares owned by SofTech,
represented approximately 88.86% of the issued and outstanding Shares of the
Company.

         Pursuant to the terms of the Merger Agreement, the Purchaser intends to
exercise the Purchase Option such that after such exercise which it would own
beneficially at least 90% of the Shares. Any remaining publicly held Shares
(other than Shares with respect to which the holder exercises appraisal rights
under Delaware law) will be acquired for $2.00, net to the seller, without
interest, in the Merger upon the satisfaction or wavier of the conditions to the
Merger in the Merger Agreement. As a result of the purchase of tendered Shares
by the Purchaser in the Offer and the exercise of the Purchase Option, SofTech
and the Purchaser will be able to consummate the Merger without the vote of the
other holders of Shares in accordance with the DGCL.

         Pursuant to the terms of the Merger Agreement, on account of the fact
that the Purchaser has accepted for purchase at least two-thirds of the
outstanding Shares upon the expiration of the initial offering period, as of
December 18, 2002, SofTech, the Purchaser and the then current executive officer
and directors of the Company executed the Escrow Agreement, in the form attached
as Exhibit B to the Merger Agreement, SofTech delivered the Escrow Amount to the
Escrow Agent and all of the then current executive officer and directors of the
Company resigned their positions with the exception of Frederick H. Phillips who
remained on the Company's board of directors as the Independent Director. As of
December 19, 2002, Mr. Phillips appointed the Purchaser Directors, Joseph P.
Mullaney, Jean J. Croteau and Victor G. Bovey, to the Company's board of
directors.

         On December 19, 2002, SofTech, on behalf of the Purchaser, issued a
press release announcing the completion of the Offer. A copy of the press
release is attached to this Amendment as Exhibit (a)(5)(D)

                                                                    Page 8 of 10

and is incorporated herein by reference."
