<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our bylaws and certificate of incorporation limit the liability of our directors and officers
for expenses to the maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach of their fiduciary
duties as directors, except for liability (i)&nbsp;for any breach of their duty of loyalty to the
corporation or its stockholders; (ii)&nbsp;for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law; (iii)&nbsp;for unlawful payments of dividends or
unlawful stock repurchases or redemptions as provided in Section&nbsp;174 of the Delaware General
Corporation Law; or (iv)&nbsp;for any transaction from which the director derived an improper personal
benefit.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our bylaws and certificate of incorporation provide that we must indemnify our directors and
may indemnify our other officers, employees and agents to the fullest extent permitted by law.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have entered into agreements to indemnify our directors and officers, in addition to
indemnification provided for in our bylaws and certificate of incorporation. These agreements,
among other things, indemnify our directors and officers for certain expenses (including attorneys&#146;
fees), judgments, fines and settlement amounts incurred by any such person in any action or
proceeding, including any action by or in the right of Sipex, arising out of such person&#146;s services
as a director, officer, employee or agent of Sipex or any other company or enterprise to which the
person provides services at our request.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our bylaws also permit us to secure insurance on behalf of any officer, director, employee or
other agent for any liability arising out of his or her actions in such capacity, regardless of
whether the bylaws and
certificate of incorporation would permit indemnification. We also maintain an insurance
policy insuring our directors and officers against liability for certain acts and omissions while
acting in their official capacities.

deviation from the low or high end of the estimated maximum offering range may be reflected in the
form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in

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 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 Act and
will be governed by the final adjudication of such issue.

Pursuant to Rule 416(a) of Regulation C under the Securities Act of 1933, as amended (the "Securities Act"), this Registration Statement shall also cover any additional shares of the
Registrant's Common Stock that become issuable under the Stand-Alone Option Agreements by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without
receipt of consideration that increases the number of outstanding shares of Registrant's Common Stock.
(2)
Such shares are issuable upon exercise of outstanding options with fixed exercise prices. Pursuant to Rule 457(h)(1) of Regulation C under the Securities Act, the aggregate offering price and
the fee have been computed upon the basis of the price at which the options may be exercised. The Proposed Maximum Offering Price Per Share represents a weighted average of the exercise prices
for such shares. With respect to 1,939,470 shares subject to outstanding options to purchase Common Stock under stand-alone option agreements for employees described above, the range of exercise
prices is $1.49 per share to $3.55 per share and the Proposed Maximum Offering Price Per Share is equal to the weighted average exercise price of $2.1711 per share.
(3)
Such shares are issuable upon exercise of outstanding options with fixed exercise prices. Pursuant to Rule 457(h)(1) of Regulation C under the Securities Act, the aggregate offering price and
the fee have been computed upon the basis of the price at which the options may be exercised. The Proposed Maximum Offering Price Per Share represents a weighted average of the exercise prices
for such shares. With respect to 262,500 shares subject to outstanding options to purchase Common Stock under stand-alone option agreements for directors described above, the range of exercise
prices is $1.88 per share to $3.45 per share and the Proposed Maximum Offering Price Per Share is equal to the weighted average exercise price of $2.7991 per share.
(4)
Such shares are issuable upon exercise of an outstanding option with a fixed exercise price. Pursuant to Rule 457(h)(1) of Regulation C under the Securities Act, the aggregate offering price
and the fee have been computed upon the basis of the price at which the options may be exercised. The Proposed Maximum Offering Price Per Share represents the exercise prices for such shares.

Item 3. Incorporation of Documents by Reference.
The following documents filed by SIPEX Corporation (the "Registrant") with the SEC pursuant to
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), are incorporated in this
Registration Statement by reference as of their respective dates:
(a) The Registrant's Annual Report on Form 10-K for the period ended December 31, 2005, filed
with the SEC on August 17, 2006;
(b) All other reports filed pursuant to Section 13(a) or 15(d) of the Exchange Act
since the end of the latest fiscal year covered by the documents referred to in (1) above; and
(c) The section entitled "Description of Registrant's Securities to be Registered" contained
in the Registrant's registration statement on Form 8-A filed with the SEC on October 28, 2003
pursuant to Section 12(g) of the Exchange Act.
All documents subsequently filed with the SEC by the Registrant pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a post-effective amendment which
indicates that all securities offered herein 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 a part hereof from the date of filing of such documents; provided, however,
that we are not incorporating any information from any filed documents furnished under either Item
2.02 or Item 7.01 of any Current Report on Form 8-K.
Item 4. Description of Securities.
Not applicable.
Item 5. Interest of Named Experts and Counsel
Not applicable.
Item 6. Indemnification of Directors and Officers.
Our bylaws and certificate of incorporation limit the liability of our directors and officers
for expenses to the maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach of their fiduciary
duties as directors, except for liability (i) for any breach of their duty of loyalty to the
corporation or its stockholders; (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law; (iii) for unlawful payments of dividends or
unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General
Corporation Law; or (iv) for any transaction from which the director derived an improper personal
benefit.
Our bylaws and certificate of incorporation provide that we must indemnify our directors and
may indemnify our other officers, employees and agents to the fullest extent permitted by law.
We have entered into agreements to indemnify our directors and officers, in addition to
indemnification provided for in our bylaws and certificate of incorporation. These agreements,
among other things, indemnify our directors and officers for certain expenses (including attorneys'
fees), judgments, fines and settlement amounts incurred by any such person in any action or
proceeding, including any action by or in the right of Sipex, arising out of such person's services
as a director, officer, employee or agent of Sipex or any other company or enterprise to which the
person provides services at our request.
Our bylaws also permit us to secure insurance on behalf of any officer, director, employee or
other agent for any liability arising out of his or her actions in such capacity, regardless of
whether the bylaws and
certificate of incorporation would permit indemnification. We also maintain an insurance
policy insuring our directors and officers against liability for certain acts and omissions while
acting in their official capacities.

Item 9. Undertakings.
(a) The undersigned Registrant hereby undertakes:
(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;
(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 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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in
volume and price represent no more than a 20% change in the maximum aggregate offering price set
forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and
(iii) To include any material information with respect to the plan of distribution not
previously disclosed in the Registration Statement or any material change to such information in
the Registration Statement;
Table of Contents
provided, however
, that paragraphs (a)(1)(i) and (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 SEC by the Registrant pursuant to Section 13 or Section
15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration
Statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each
such 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 that 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 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 any 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
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 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
Securities and Exchange Commission such indemnification is against public policy as expressed in
the 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 Act and
will be governed by the final adjudication of such issue.
