by reference:

         (a) Allaire's Prospectus dated January 22, 1999 included in 
Allaire's registration statement on Form S-1, File Number 333-68639, as 
declared effective by the Commission on January 22, 1999;

         (b) the description of Allaire's common stock contained in the 
registration statement on Form 8-A filed with the Commission on January 15, 
1999 under Section 12 of the Securities Exchange Act of 1934, including any 
amendment or report filed for the purpose of updating such description;

on December 31, 1998, as filed with the Commission on March 31, 1999; and

         (d) Allaire's Current Report on Form 8-K as filed with the

         All documents subsequently filed by Allaire pursuant to Sections 
13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as 
amended, prior to the filing of a post-effective amendment which indicates 
that all securities offered have been sold or which deregisters all 
securities then remaining unsold, shall be deemed to be incorporated by 
reference in this Registration Statement and to be part hereof from the date 
of filing of such documents.

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         The validity of the securities registered hereby is being passed 
upon for Allaire Corporation by Foley, Hoag & Eliot LLP, Boston, 
Massachusetts.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
                                     
         Section 145 of the Delaware General Corporation Law affords a 
Delaware corporation the power to indemnify its present and former directors 
and officers under certain conditions. Article Six of Allaire's Amended and 
Restated Certificate of Incorporation provides that Allaire will indemnify 
each person who at any time is, or has been, a director or officer of Allaire 
and was or is a party or is threatened to be made a party to any threatened, 
pending or completed action, suit or proceeding, whether civil, criminal, 
administrative or investigative, by reason of the fact that he or she is or 
was a director or officer of Allaire or is or was serving at our request as a 
director, officer, employee, or agent of another corporation, partnership, 
joint venture, trust or other



enterprise against expenses (including attorneys' fees), judgments, fines and 
amounts paid in settlement incurred in connection with any such action, suit 
or proceeding, to the maximum extent permitted by the Delaware General 
Corporation Law, as the same exists or may hereafter be amended. No amendment 
to or repeal of the provisions of Article Six of the Amended and Restated 
Certificate of Incorporation will deprive a director or officer of the 
benefit thereof with respect to any act or failure occurring prior to such 
amendment or repeal.

         Section 102(b)(7) of the Delaware General Corporation Law gives a 
Delaware corporation the power to adopt a charter provision eliminating or 
limiting the personal liability of directors to the corporation or its 
stockholders for breach of fiduciary duty as directors, provided that such 
provision may not eliminate or limit the liability of directors for: (a) any 
breach of the director's duty of loyalty to the corporation or its 
stockholders; (b) any acts or omissions not in good faith or which involve 
intentional misconduct or a knowing violation of law; (c) any payment of a 
dividend or approval of a stock purchase that is illegal under Section 174 of 
the Delaware General Corporation Law; or (d) any transaction from which the 
director derived an improper personal benefit.

         Article Eight of Allaire's Amended and Restated Certificate of 
Incorporation provides that to the maximum extent permitted by the Delaware 
General Corporation Law, no director will be personally liable to Allaire or 
to any of its stockholders for monetary damages arising out of such 
director's breach of fiduciary duty as a director. No amendment to or repeal 
of the provisions of Article Eight will apply to or have any effect on the 
liability or the alleged liability of any director with respect to any act or 
failure to act of such director occurring prior to such amendment or repeal. 
A principal effect of Article Eight is to limit or eliminate the potential 
liability of Allaire's directors for monetary damages arising from breaches 
of their duty of care, unless the breach involves one of the four exceptions 
described in (a) through (d) above.

         Section 145 of the Delaware General Corporation Law also affords a 
Delaware corporation the power to obtain insurance on behalf of its directors 
and officers against liabilities incurred by them in those capacities. 
Allaire has obtained a directors' and officers' liability and company 
reimbursement liability insurance policy that: (a) insures directors and 
officers against losses (above a deductible amount) arising from certain 
claims made against them by reason of certain acts done or attempted by such 
directors or officers; and (b) insures Allaire against losses (above a 
deductible amount) arising from any such claims, but only if Allaire is 
required or permitted to indemnify such directors or officers for such losses 
under statutory or common law or under provisions of its Amended and Restated 
Certificate of Incorporation or Amended and Restated By-Laws.

ITEM 9.  UNDERTAKINGS.

         1. The undersigned registrant hereby undertakes that, for purposes 
of determining any liability under the Securities Act of 1933, each filing of 
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of 
the Securities Exchange Act of 1934 (and, where applicable, each filing of an 
employee benefit plan's annual report pursuant to Section 15(d) of the 
Securities Exchange Act of 1934) that is incorporated by reference in the 
registration statement will be deemed to be a new registration statement 
relating to the securities offered therein, and the offering of such 
securities at that time will be deemed to be the initial BONA FIDE offering 
thereof.

         2. The undersigned registrant hereby undertakes:

                  (a) 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;

                           (ii) To reflect in the prospectus any facts or events
                  arising after the effective date of the 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 the registration
                  statement. Notwithstanding the foregoing, any increase or
                  decrease in volume of securities offered (if the total dollar
                  value of securities offered would not exceed that which was
                  registered) and any deviation from the low or high end of the
                  estimated maximum offering range may be reflected in the form
                  of prospectus filed with the Commission pursuant to Rule
                  424(b) if, in the aggregate, the changes in volume and price
                  represent no more than a 20 percent change in the maximum
                  aggregate offering price set forth in the "Calculation of
                  Registration Fee" table in the effective registration
                  statement.

                           (iii) To include any material information with
                  respect to the plan of distribution not previously disclosed
                  in the registration statement or any material

                                    II-3

                  change to such information in the registration statement;


PROVIDED, HOWEVER, that paragraphs 2 (a)(1)(i) and 2 (a)(1)(ii) do not apply 
if the information required to be included in a post-effective amendment by 
those paragraphs is contained in periodic reports filed with or furnished to 
the Commission by the registrant pursuant to Section 13 or 15(d) of the 
Securities Exchange Act of 1934 that are incorporated by reference herein.

                  (b) That, for the purpose of determining any liability 
under the Securities Act of 1933, each such post-effective amendment will 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) 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.

         3. Insofar as indemnification for liabilities arising under the 
Securities Act of 1933 may be permitted to directors, officers and 
controlling persons of the registrant pursuant to the foregoing provisions, 
or otherwise, the registrant has been advised that in the opinion of the 
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.

                                    II-4     



                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the 
registrant certifies that it has reasonable grounds to believe that it meets 
all of the requirements for filing on Form S-8 and has duly caused this 
registration statement to be signed on its behalf by the undersigned, 
thereunto duly authorized, in the City of Cambridge, Commonwealth of 
Massachusetts, on this 12th day of May, 1999.
