                                   THE COMPANY

The Company develops and markets software that is used in the creation,
management and distribution of documents. The Company's software enables
customers to compose, edit, view and print documents, while also facilitating
their electronic management, preparation, conversion and distribution. The
Company offers its customers an integrated document publishing ("IDP") solution
to meet both the needs of the document author and information user. The
Company's principal offices are located at 62 Fourth Avenue, Waltham,
Massachusetts 02154, and its telephone number is (781) 290-0710.

                                  RISK FACTORS

This Prospectus contains forward-looking statements that involve risks and
uncertainties. Actual results could differ materially from those discussed in
the forward looking statements as a result of certain factors, including the
factors set forth below and elsewhere in this Prospectus.

The following risk factors should be considered carefully in addition to the
other information contained in this Prospectus before purchasing the Common
Stock offered hereby.

Fluctuations and Uncertainty of Future Operating Results. The Company's revenues
have declined significantly in recent years, and its operating results have
fluctuated, as a result of changes in the marketplace for the Company's
traditional products, and the aging of its technology. The Company's future
operating results are dependent on its ability to develop and market IDP
software products and services that meet the changing needs of organizations
with complex document publishing requirements. There are numerous risks
associated with this process, including rapid technological change in the
information technology industry and the requirement to bring to market IDP and
web-based applications that solve complicated business needs in a timely manner.
To the extent that the Company's traditional complex authoring products have not
adopted or fail to adopt to changes in technology, sales of these products may
continue to decline.

Year 2000 Compliance. The Company has undertaken a systematic review and
planning process concerning the requirements and abilities of its standard
products (including embedded third party products) to handle date information
and to function appropriately from and after January 1, 2000. The Company
intends to discontinue its support of certain products which it considers
obsolete, without regard to Year 2000 concerns. Although the Company believes
that the effort required to adapt its supported standard products to function
appropriately from and after January 1, 2000 will not have a materially adverse
impact on the Company's financial performance, currently unforeseen
difficulties, delays or requirements could cause this assessment to change. Many
of the Company's customers have implemented custom applications which rely on
the Company's standard products to operate. The Company does not believe that it
has the obligation to modify such applications to function appropriately from
and after January 1, 2000. It is possible that unforeseen liabilities may arise
with respect to discontinued products or custom applications. To the extent that
the Company's traditional complex authoring products are not adapted to address
customers' Year 2000 concerns, sales of these products may continue to decline.

The Company has also undertaken a comprehensive evaluation of its internal
information systems in order to evaluate any improvements or replacements that
may be required in order to address Year 2000 functionality and other
operational deficiencies. This review is not complete, and the Company cannot
estimate the cost or risk which may be associated with its Year 2000 or other
operational issues. The Company expects to have the evaluation and planning
process completed, and to begin any necessary corrective action, by the end of
the current fiscal year.

Intense Competition. The existing document publishing, electronic distribution,
and document management markets in which the Company competes are highly
competitive. Many of these competitors are larger and better funded than the
Company. The Company competes for sales of its software products on both an
individual product basis, and as integrated with consulting services in large
IDP solution sales.

Retention of Key Employees, Customers, Vendors and Distributors. Given the
reduction in the Company's revenues and employee base over recent periods, and
given the current extremely competitive labor conditions, the Company expects to
face difficulties in managing and implementing its plans for growth, including
without limitation difficulties in attracting and retaining key technical, sales
and executive personnel, and difficulties in managing relationships with
distributors, vendors, customers and other third parties.


                                       3


Lengthy Sales and Implementation Cycles. Sales cycles associated with IDP
solution sales are long because organizations frequently require the Company to
solve complex business problems that typically involve reengineering of their
business processes. In addition, a high percentage of the Company's product
license revenues are generally realized in the last month of a fiscal quarter
and can be difficult to predict until the end of a fiscal quarter. Accordingly,
given the Company's relatively fixed cost structure, a shortfall or increase in
product license revenue can have a significant impact on the Company's operating
results and liquidity.

Markets for Products. The Company markets its software products and services
worldwide. Global and/or regional economic factors, currency exchange rate
fluctuations, and potential changes in laws and regulations affecting the
Company's business could impact the Company's financial condition or future
operating results.

Possible Volatility of Share Price. The market price of the Company's Common
Stock may be volatile at times in response to fluctuations in the Company's
quarterly operating results, changes in analysts' earnings estimates, market
conditions in the computer software industry, as well as general economic
conditions and other factors external to the Company.

                                 USE OF PROCEEDS

The Company will not receive any proceeds from the sale of Common Stock by the
Selling Shareholder.


                            SELLING SECURITY HOLDERS

This Prospectus relates to possible sales of the Company's shares of Common
Stock by Jaime W. Ellertson, President, CEO and Director of the Registrant (the
"Selling Shareholder") to the extent now or hereafter permitted by the rules and
regulations promulgated under the Securities Act.

Prior to this offering, the Selling Shareholder held 19,100 shares of Common
Stock, plus an option to purchase 725,000 shares under the 1997 Key Man Plan.
Only the shares subject to the option granted under the 1997 Key Man Plan are
being offered for sale pursuant to this Prospectus. Assuming the sale of all the
shares offered hereby are sold, the Selling Shareholder will beneficially own
19,100 shares of Common Stock (less than 1% of the Common Stock outstanding).

                              PLAN OF DISTRIBUTION

         The shares of Common Stock are being sold by the Selling Shareholder
for his own account. The Common Stock may be sold or transferred for value in
one or more transactions on the Nasdaq National Market, in negotiated
transactions or in a combination of such methods of sale, at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices or at prices otherwise negotiated. The Selling Shareholder may effect
such transactions by selling the shares of Common Stock to or through
broker/dealers, and such broker/dealers may receive compensation in the form of
underwriting discounts, concessions or commissions from the Selling Shareholder
and/or the purchasers of the shares of Common Stock for whom such broker/dealers
may act as agent. Usual and customary brokerage fees will be paid by the Selling
Shareholder.


There can be no assurance that the Selling Shareholder will sell any or all of
the shares of Common Stock offered hereunder.

Registrant. If any such action is disposed of, on the merits or otherwise,
without the disposition being adverse to the director or officer and without an
adjudication that such person did not act in good faith in the reasonable belief
that his action was in the best interests of the Registrant, the director or
officer is entitled to indemnification as a matter of right. In all other cases,
indemnification shall be made as of right unless after investigation (a) by the
Board of Directors by a majority vote of a quorum of disinterested directors, or
(b) by written opinion of independent legal counsel (who may be regular counsel
of the Registrant), or (c) the holders of a majority of outstanding stock
entitled to vote (exclusive of stock owned by any interested directors or
officers), it shall be determined by clear and convincing evidence that such
person did not act in good faith and in a manner reasonably believed to be in or
not opposed to the best interest of the Registrant. Indemnification may include
advancement of expenses of defending an action upon receipt of an undertaking by
the person indemnified to repay such advances if it is ultimately determined
that such person is not entitled to indemnification under Article V. Article V
also provides that the right of indemnification provided therein is not
exclusive of and does not affect any other rights to which any director or
officer may be entitled under any agreement, statute, vote of stockholders or
otherwise. The Registrant's obligation to indemnify under Article V shall be
offset to the extent of any other source of indemnification or any otherwise
applicable insurance coverage.

         (c) The Registrant has entered into an Agreement to Defend and
Indemnify with each of its officers and directors. Pursuant to these agreements,
the Registrant has agreed, to the extent legally permissible, to indemnify such
persons against all losses (including, without limitation, judgments, fines and
penalties) and expenses (including, without limitation, amounts paid in
settlement and counsel fees and disbursements) incurred by such person in
connection with or as a result of any claim, action, suit or other proceeding,
civil or criminal, or appeal related thereto, in which he may be involved by
reason of his having been a director or officer or by reason of any action taken
or not taken in his capacity as director or officer; provided that no
indemnification shall be provided with respect to any matter as to which such
person shall not have acted in good faith in the reasonable belief that his
action was in the best interests of the Registrant. If any such claim, action,
suit or proceeding is disposed of, on the merits or otherwise, without the
disposition being adverse to such person, without a plea of guilty or NOLO
CONTENDRE and without an adjudication that such person did not act in good faith
in the reasonable belief that his action was in the best interests of the
Registrant, the director or officer is entitled to indemnification as a matter
of right. In all other cases, indemnification shall be made upon a determination
that such person's conduct was in good faith and in the reasonable belief that
his action was in the best interests of the Registrant by (a) a quorum of
disinterested directors, or (b) independent legal counsel (who may be regular
counsel of the Registrant), or (c) the holders of a majority of outstanding
stock entitled to vote (exclusive of stock owned by an interested directors or
officer). Expenses may be advanced by the Registrant prior to any final
disposition of any such action upon receipt of an undertaking by the person
indemnified to repay such advances if it is ultimately determined that such
person is not entitled to indemnification under the Agreement. Such Agreements
provide that the right of indemnification provided therein is in addition to any
rights to which any person concerned may be entitled by other agreements or as a
matter of law, and shall inure to the benefit of the heirs, executors and
administrators of the indemnified person. The rights of indemnification provided
in such Agreements are in addition to any rights under any insurance policy in
effect, provide that to the extent any claim is covered by any such insurance
policy, the Registrant will provide coverage after the full coverage of the
insurance policy is exhausted or otherwise unavailable.

         (d) Article 6D of the Registrant's Articles of Organization provides
that, to the fullest extent permitted by Chapter 156B of the Massachusetts
General Laws, a director of the Registrant shall not be 


                                      II-2



personally liable to the Registrant or its stockholders for monetary damages for
breach of fiduciary duty as a director, notwithstanding any provision of law
imposing such liability. Section 13(b)(1 1/2) of Chapter 156B of the
Massachusetts General Laws permits a corporation to include in its articles of
organization a provision eliminating or limiting the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary as a director, except for (i) any breach of the director's duty of
loyalty to the corporation and its stockholders, (ii) acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of the
law, (ii) improper issuances of stock or unauthorized distributions to
stockholders, or (iv) any transaction in which the director derived an improper
personal benefit.

Item 9.           Undertakings.

The Registrant hereby undertakes:

(a)(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

       (i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933, as amended (the "Securities Act");

       (ii) To reflect in the prospectus any facts or events arising after the
effective date of this Registration Statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in this Registration Statement;

       (iii) To include any material information with respect to the plan of
distribution not previously disclosed in this Registration Statement or any
material change to such information in this Registration Statement; provided,
however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information 

- --------------------------
* Not filed herewith. In accordance with Rule 411 promulgated pursuant to the
Securities Act of 1933, as amended, reference is made to the documents
previously filed with the Commission, which are incorporated by reference
herein.


                                      II-3



required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the Registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act") that are incorporated by reference in this Registration Statement.

    (2) That, for the purposes of determining any liability under the Securities
Act, each post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at the time shall be deemed to be the initial bona fide offering
thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

(b) The Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof

(c) Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the indemnification provisions described herein, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
