                                EXPLANATORY NOTE
 
    This Amendment No. 3 includes an addition to Exhibit 3.1, the Certificate of
Incorporation of Celerity Systems, Inc, which was previously filed with the
Securities and Exchange Commission. The Prospectus which forms a part of this
Registration Statement has not been changed from that included in Amendment No.
2, as filed with the Securities and Exchange Commission on October 27, 1997.

                                    PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 24. INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
    Delaware General Corporation Law, Section 102(b)(7), enables a corporation
in its original certificate of incorporation, or an amendment thereto validly
approved by stockholders, to eliminate or limit personal liability of members of
its Board of Directors for violations of a director's fiduciary duty of care.
However, the elimination or limitation shall not apply where there has been a
breach of the duty of loyalty, failure to act in good faith, intentional
misconduct or a knowing violation of a law, the payment of a dividend or
approval of a stock repurchase which is deemed illegal or an improper personal
benefit is obtained. The Company's Certificate of Incorporation includes the
following language:
 
    "No director of the Corporation shall be liable to the Corporation or any of
its stockholders for monetary damages for breach of fiduciary duty as a
director, provided that this provision does not eliminate or limit the liability
of the director (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of Title 8 of the Delaware Code, or (iv) for any transaction from
which the director derived an improper personal benefit. For purposes of the
prior sentence, the term "damages" shall, to the extent permitted by law,
include, without limitation, any judgment, fine, amount paid in settlement,
penalty, punitive damages, excise, or other tax, including, without limitation,
any of the foregoing incurred or assessed with respect to an employee benefit
plan, or expense of any nature (including, without limitation, counsel fees and
disbursements)." According to the Certificate of Incorporation, the limitations
of liability discussed in this provision cannot be limited by a modification of
the Certificate of Incorporation for acts that occurred prior to that
modification.
 
    Article NINTH of the Certificate of Incorporation of the Company, permits
indemnification of, and advancement of expenses to, among others, officers and
directors of the Corporation. Such Article provides as follows:
 
    "A. Each person who was or is made a party or is threatened to be made a
party to or is otherwise involved in any action, suit, or proceeding, whether
civil, criminal, administrative, or investigative (hereinafter a "proceeding"),
by reason of the fact that he or she is or was a director, officer, employee, or
agent of the Corporation or any of its direct or indirect subsidiaries or is or
was serving at the request of the Corporation as a director, officer, employee,
or agent of any other corporation or of a partnership, joint venture, trust, or
other enterprise, including service with respect to an employee benefit plan
(hereinafter an "indemnitee"), whether the basis of such proceeding is alleged
action in an official capacity as a director, officer, employee, or agent or in
any other capacity while serving as a director, officer, employee, or agent,
shall be indemnified and held harmless by the Corporation to the fullest extent
authorized by the Delaware Code, as the same exists or may hereafter be amended
(but, in the case of any such amendment, only to the extent that such amendment
permits the Corporation to provide broader indemnification rights than permitted
prior thereto), against all expense, liability, and loss (including attorneys'
fees, judgments, fines, excise or other taxes assessed with respect to an
employee benefit plan, penalties, and amounts paid in settlement) reasonably
incurred or suffered by such indemnitee in connection therewith, and such
indemnification shall continue as to an indemnitee who has ceased to be a
director, officer, employee, or agent and shall inure to the benefit of the
indemnitee's heirs, executors, and administrators; provided, however, that,
except as provided in Paragraph C of this Article Ninth with respect to
proceedings to enforce rights to indemnification, the Corporation shall
indemnify any such indemnitee in connection with a proceeding (or part thereof)
initiated by such indemnitee only if such proceeding (or part thereof) was
authorized by the Board of Directors of the Corporation."
 
    "B. The right to indemnification conferred in paragraph A of this Article
Ninth shall include the right to be paid by the Corporation the expenses
incurred in defending any proceeding for which such right to indemnification is
applicable in advance of its final disposition (hereinafter an "advancement of
 
                                      II-1

expenses"); PROVIDED, HOWEVER, that, if the Delaware Code so requires, an
advancement of expenses incurred by an indemnitee in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such indemnitee, including, without limitation, service to an
employee benefit plan) shall be made only upon delivery to the Corporation of an
undertaking (hereinafter an "undertaking"), by or on behalf of such indemnitee,
to repay all amounts so advanced if it shall ultimately be determined by final
judicial decision from which there is no further right to appeal (hereinafter a
"final adjudication") that such indemnitee is not entitled to be indemnified for
such expenses under this Article Ninth or otherwise."
 
    "C. The rights to indemnification and to the advancement of expenses
conferred in paragraphs A and B of this Article Ninth shall be contract rights.
If a claim under paragraph A or B of this Article Ninth is not paid in full by
the Corporation within 60 days after a written claim has been received by the
Corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be 20 days, the indemnitee may at any
time thereafter bring suit against the Corporation to recover the unpaid amount
of the claim. If successful in whole or in part in any such suit, or in a suit
brought by the Corporation to recover an advancement of expenses pursuant to the
terms of an undertaking, the indemnitee shall be entitled to be paid also the
expense of prosecuting or defending such suit. In (i) any suit brought by the
indemnitee to enforce a right to indemnification hereunder (but not in a suit
brought by an indemnitee to enforce a right to an advancement of expenses) it
shall be a defense that, the indemnitee has not met any applicable standard for
indemnification set forth in the Delaware Code, and (ii) any suit by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the Corporation shall be entitled to recover such expenses upon a
final adjudication that, the indemnitee has not met any applicable standard for
indemnification set forth in the Delaware Code. Neither the failure of the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Delaware Code, nor an actual determination by the Corporation (including its
Board of Directors, independent legal counsel, or its stockholders) that the
indemnitee has not met such applicable standard of conduct, shall create a
presumption that the indemnitee has not met the applicable standard of conduct
or, in the case of such a suit brought by the indemnitee, be a defense to such
suit. In any suit brought by the indemnitee to enforce a right to
indemnification or to an advancement of expenses hereunder, or by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the burden of proving that the indemnitee is not entitled to be
indemnified, or to such advancement of expenses, under this Article Ninth or
otherwise, shall be on the Corporation."
 
    "D. The rights to indemnification and to the advancement of expenses
conferred in this Article Ninth shall not be exclusive of any other right which
any person may have or hereafter acquire under any statute, this certificate of
incorporation, by-law, agreement, vote of stockholders or disinterested
directors, or otherwise."
 
    "E. The Corporation may maintain insurance, at its expense, to protect
itself and any director, officer, employee, or agent of the Corporation or
another corporation, partnership, joint venture, trust, or other enterprise
against any expense, liability, or loss, whether or not the Corporation would
have the power to indemnify such person against such expense, liability, or loss
under the Delaware Code."
 
    "F. The Corporation's obligation, if any, to indemnify any person who was or
is serving as a director, officer, employee, or agent of any direct or indirect
subsidiary of the Corporation or, at the request of the Corporation, of any
other corporation or of a partnership, joint venture, trust, or other enterprise
shall be reduced by any amount such person may collect as indemnification from
such other corporation, partnership, joint venture, trust, or other enterprise."
 
    "G. Any repeal or modification of the foregoing provisions of this Article
Ninth shall not adversely affect any right or protection hereunder of any person
in respect of any act or omission occurring prior to the time of such repeal or
modification."

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES
 
    In the past three years, the Registrant has made the following sales of
unregistered securities, all of which sales were exempt from the registration
requirements of the Securities Act pursuant to Section 4(2) thereof or as
otherwise indicated herein. The following section gives effect to the
one-for-two-and-one-half reverse stock split of the Company's Common Stock
effected in August 1997.
 
    In May 1995, the Company sold 975,836 shares of Series A Preferred Stock at
$1.55 per share (including 160,764 shares of Series A Preferred Stock sold to
Herzog, Heine & Geduld, Inc., a customer of the Company, as a result of the
conversion of a loan in the principal amount of $250,000 received from such
customer in April 1994) and warrants to purchase 408,479 shares of Series B
Preferred Stock at $1.96 per share for an aggregate purchase price of
$1,517,500, solely to accredited investors. The warrants to purchase the shares
of Series B Preferred Stock were exercised in August 1995 and the Company issued
163,392 shares of Series B Preferred Stock solely to accredited investors. The
Company believes that the issuance and sale of such securities was exempt from
registration pursuant to Section 4(2) of the Securities Act and/or Rule 506
promulgated thereunder.
 
    In November 1995, the Company issued subordinated debt in the principal
amount of $934,500 solely to accredited investors, many of which had
participated in the previous preferred stock offerings. Such debt bore interest
at 10% per annum and, if not paid by November 30, 1996, automatically converted
to Common Stock at a rate of $4.90 per share. Purchasers of the debt received
the 1995 Warrants to purchase 190,714 shares of the Company's Common Stock for
an aggregate purchase price equal to the principal amount of the debt
($934,500). The 1995 Warrants expire on the earlier of (i) May 31, 1998 and (ii)
the closing of the Offering. Accordingly, such warrants will expire if not
exercised prior to the consummation of the Offering. The debt was automatically
converted to 190,714 shares of Common Stock in November 1996. All interest,
which had been accrued on the debt, was forgiven. The Company believes that each
issuance and sale of such securities was exempt from registration pursuant to
Section 4(2) of the Securities Act and/or Rule 506 promulgated thereunder.
 
    In December 1995, the Company issued 17,915 shares of Common Stock to Dr.
Fenton Scruggs, a director of the Company and an accredited investor, as a
result of the conversion of a loan in the principal amount of $75,000 received
from Dr. Scruggs in November 1994. The Company believes that such issuance and
sale was exempt from registration pursuant to Section 4(2) of the Securities
Act.
 
                                      II-3

    In June 1996, the Company, through Hampshire Securities Corporation, acting
as placement agent, issued and sold 60 units of its securities, each consisting
of 7,111 shares of Common Stock, one 10% Note in the principal amount of $50,000
and one three-year 1996 Warrant to purchase 2,625 shares of Common Stock at an
exercise price equal to $8.46 per share, at $100,000 per unit ($6,000,000 total)
solely to accredited investors. The Company believes that each issuance and sale
of such securities was exempt from registration pursuant to Section 4(2) of the
Securities Act and Rule 506 promulgated thereunder. Hampshire Securities
Corporation received, for its services, a placement fee of 8% of the gross
proceeds from the sale of such securities, a warrant to purchase 38,852 shares
of Common Stock at an exercise price of $9.44 per share, and reimbursement of
certain other expenses.
 
    On July 15, 1997, the Company, through Hampshire Securities Corporation,
acting as placement agent, commenced the offer of 20 units of its securities,
each consisting of one 10% Note in the principal amount of $100,000 and one
four-year Warrant to purchase 16,000 shares of Common Stock at an exercise price
equal to $3.00 per share, at $100,000 per unit ($2,000,000 total) solely to
accredited investors. The Company believes that such issuance and sale of such
securities was exempt from registration pursuant to Section 4(2) of the
Securities Act and/or Rule 506 promulgated thereunder. At the closing of such
offering on August 8, 1997, Hampshire Securities Corporation received, for its
services, a placement fee of 10% of the gross proceeds from the sale of such
securities and reimbursement of certain other expenses.
 
    The Company's currently outstanding options to purchase 129,400 shares of
Common Stock under the 1995 Plan were granted from August 10, 1995 through April
4, 1997 at exercise prices ranging from $0.10 to $4.90 per share, although
substantially all of such options are exercisable at $0.10 per share. The
Company believes that the issuance of such securities was exempt from
registration under Rule 701 under the Securities Act. In addition to the options
granted under the 1995 Plan, the Company granted to accredited investors between
April 4, 1997 and July 18, 1997 options to purchase 513,200 shares of Common
Stock outside of the 1995 Plan at exercise prices ranging from $0.10 to $3.00,
30,000 of which have been cancelled. The Company believes that each such
issuance and sale of securities was exempt from registration pursuant to Section
4(2) of the Securities Act.

ITEM 28. UNDERTAKINGS
 
    (a) The undersigned Registrant hereby undertakes:
 
        (1) to file, during any period in which it offers or sells securities, a
    post-effective amendment to this registration statement to
 
        (i) include any prospectus required by section 10(a)(3) of the
    Securities Act;
 
        (ii) to reflect in the prospectus any facts or events which,
    individually or together, represent a fundamental change in the information
    in the registration statement;
 
       (iii) to include any additional or changed material information on the
    plan of distribution;
 
        (2) for determining liability under the Securities Act, treat each
    post-effective amendment as a new registration statement of securities
    offered, and the offering of such securities at that time be the initial
    bona fide offering thereof; and
 
        (3) file a post-effective amendment to remove from registration any of
    the securities that remain unsold at the termination of the offering.
 
    (d) The Registrant hereby undertakes that it will provide to the
Underwriters at the closing specified in the underwriting agreement certificates
in such denominations and registered in such names as required by the
underwriter to permit prompt delivery to each purchaser.
 
    (e) 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 foregoing provisions, 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.
 
    (f) The undersigned Registrant hereby undertakes that it will:
 
        (1) for determining any liability under the Securities Act, treat the
    information omitted from the form of prospectus filed as part of this
    registration statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act as part of this registration statement as of
    the time the Commission declared it effective; and
 
        (2) determining any liability under the Securities Act, treat each
    post-effective amendment that contains a form of prospectus as a new
    registration statement for the securities offered therein, and the offering
    of such securities at that time as the initial bona fide offering thereof.
