              INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Documents by Reference

         CoorsTek, Inc. (the "Registrant") hereby incorporates by reference into
this Registration Statement the Registrant's effective registration statement,
as amended, on Form 10 filed on October 6, 1999 under the Securities Exchange
Act of 1934 (the "Exchange Act") filed by it with the Commission.

         In addition, all documents filed by the Registrant subsequent to the

and prior to the filing of a post-effective amendment which indicates that all

Registration Statement and to be part hereof from the date of filing of such

Item 4.  Description of Securities

         Not applicable (the Common Stock is registered under Section 12 of the
Exchange Act).

Item 5.  Interests of Named Experts and Counsel

         Not applicable.

Item 6.  Indemnification of Directors and Officers

         Section 145 of the Delaware General Corporation Law (the "DGCL")
permits each Delaware business corporation to indemnify its directors, officers,
employees and agents against liability for each such person's acts taken in his
or her capacity as a director, officer, employee or agent of the corporation if
such actions were taken in good faith and in a manner which he or she reasonably
believed to be in or not opposed to the best interests of the corporation, and
with respect to any criminal action, if he or she had no reasonable cause to
believe his or her conduct was unlawful. Article 6 of the Registrant's Bylaws
provides that the Registrant, to the full extent permitted by Section 145 of the
DGCL, shall indemnify all past and present directors or officers of the
Registrant and may indemnify all past or present employees or other agents of
the Registrant. To the extent that a director, officer, employee or agent of the
Registrant has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in such Article 6, or in defense of any
claim, issue or matter therein, he or she shall be indemnified by the Registrant
against actually and reasonably incurred expenses (including attorneys' fees) in
connection therewith. Such expenses may be paid by the Registrant in advance of
the final disposition of the action, suit or proceeding upon receipt of an
undertaking to repay the advance if it is ultimately determined that such person
is not entitled to indemnification. As permitted by Section 102(b)(7) of the
DGCL, Section 6.5 of the Registrant's


                                       3
<PAGE>

Certificate of Incorporation provides that no director of the Registrant shall
be liable to the Registrant for monetary damages for breach of fiduciary duty as
a director, except for liability (i) for any breach of the director's duty of
loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) for the unlawful payment of dividends on or redemption of the
Registrant's capital stock, or (iv) for any transaction from which the director
derived an improper personal benefit. The Registrant maintains a policy insuring
it and its directors and officers against certain liabilities, including
liabilities under the Securities Act.

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;


                                       4
<PAGE>

               (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; 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;

               provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
               not apply if the registration statement is on Form S-3, Form S-8
               or Form F-3, and the information required to be included in a
               post-effective amendment by those paragraphs is contained in the
               periodic reports filed by the Registrant pursuant to Section 13
               or Section 15(d) of the Exchange Act that are incorporated by
               reference in the Registration Statement.

          (2)  That, for the purpose of determining any liability under the
               Securities Act, each such post-effective amendment shall be
               deemed to be a new registration statement relating to the
               securities offered 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, each filing of the
          Registrant's annual report pursuant to Section 13(a) or Section 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 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.

                                       5
<PAGE>

     (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 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.

PART II

              INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Documents by Reference

         CoorsTek, Inc. (the "Registrant") hereby incorporates by reference into
this Registration Statement the Registrant's effective registration statement,
as amended, on Form 10 filed on October 6, 1999 under the Securities Exchange
Act of 1934 (the "Exchange Act") filed by it with the Commission.

         In addition, all documents filed by the Registrant subsequent to the

and prior to the filing of a post-effective amendment which indicates that all

Registration Statement and to be part hereof from the date of filing of such
documents or reports.

Item 4.  Description of Securities

         Not applicable (the Common Stock is registered under Section 12 of the
Exchange Act).

Item 5.  Interests of Named Experts and Counsel

         Not applicable.

Item 6.  Indemnification of Directors and Officers

         Section 145 of the Delaware General Corporation Law (the "DGCL")
permits each Delaware business corporation to indemnify its directors, officers,
employees and agents against liability for each such person's acts taken in his
or her capacity as a director, officer, employee or agent of the corporation if
such actions were taken in good faith and in a manner which he or she reasonably
believed to be in or not opposed to the best interests of the corporation, and
with respect to any criminal action, if he or she had no reasonable cause to
believe his or her conduct was unlawful. Article 6 of the Registrant's Bylaws
provides that the Registrant, to the full extent permitted by Section 145 of the
DGCL, shall indemnify all past and present directors or officers of the
Registrant and may indemnify all past or present employees or other agents of
the Registrant. To the extent that a director, officer, employee or agent of the
Registrant has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in such Article 6, or in defense of any
claim, issue or matter therein, he or she shall be indemnified by the Registrant
against actually and reasonably incurred expenses (including attorneys' fees) in
connection therewith. Such expenses may be paid by the Registrant in advance of
the final disposition of the action, suit or proceeding upon receipt of an
undertaking to repay the advance if it is ultimately determined that such person
is not entitled to indemnification. As permitted by Section 102(b)(7) of the
DGCL, Section 6.5 of the Registrant's

                                       3
Certificate of Incorporation provides that no director of the Registrant shall
be liable to the Registrant for monetary damages for breach of fiduciary duty as
a director, except for liability (i) for any breach of the director's duty of
loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) for the unlawful payment of dividends on or redemption of the
Registrant's capital stock, or (iv) for any transaction from which the director
derived an improper personal benefit. The Registrant maintains a policy insuring
it and its directors and officers against certain liabilities, including
liabilities under the Securities Act.

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;

                                       4
(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; 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;

               provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
               not apply if the registration statement is on Form S-3, Form S-8
               or Form F-3, and the information required to be included in a
               post-effective amendment by those paragraphs is contained in the
               periodic reports filed by the Registrant pursuant to Section 13
               or Section 15(d) of the Exchange Act that are incorporated by
               reference in the Registration Statement.

          (2)  That, for the purpose of determining any liability under the
               Securities Act, each such post-effective amendment shall be
               deemed to be a new registration statement relating to the
               securities offered 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, each filing of the
          Registrant's annual report pursuant to Section 13(a) or Section 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 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.

                                       5
(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 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.
