               EMPLOYMENT SEVERANCE AGREEMENT AND LEGAL RELEASE

     This Legal Release ("Agreement") is between Katherine A. Resler
("Executive") and CoorsTek, Inc., its subsidiaries, affiliates and predecessors,
and their respective officers, directors, employees, agents, representatives and
insurers (collectively "CTI").

1.   Executive acknowledges that CTI has offered to provide Executive a
severance compensation package (the "Benefit"), in part in order to resolve all
claims that Executive has or may have against CTI, and that Executive
understands the terms and conditions of the Benefit.

2.   Executive agrees that she wishes to receive the Benefit, that her decision
to do so is entirely voluntary, that she has not been pressured into accepting
the Benefit, and that she has enough information about the Benefit to decide
whether to sign this Agreement.

3.   Executive agrees that by signing this Agreement she will give up her right
to bring any legal claim against CTI of any nature, including all claims
relating in any way, directly or indirectly, to Executive's employment
relationship with CTI, including her separation from employment. Specifically,
Executive agrees that she fully and forever releases all of her legal rights and
claims against CTI, whether or not presently known to her, including future
legal rights and claims, if based in whole or part on acts or omissions
occurring before Executive delivers this signed Agreement to CTI, in any way
relating to Executive's employment with CTI, including her separation form
employment, except for her right to the Benefit, her vested rights, if any, in
any CTI-sponsored pension plan, and her rights under COBRA, if any, to continued
participation, at her expense, in certain employee benefit plans sponsored by
CTI. Executive agrees that the legal rights and claims that she is giving up
include, but are not limited to, her rights, if any, under all federal, state
and local statutes, rules and regulations that prohibit discrimination on the
basis-of gender, race, national origin, religion, disability and age, such as
the Age Discrimination in Employment Act of 1977, Title VII of the Civil Rights
Act of 1964, as amended ("Title VII'), the Rehabilitation Act of 1973, the
Americans with Disabilities Act, the Family and Medical Leave Act, the Equal Pay
Act, and any other federal, state or local civil rights statute or ordinance
that applies or may apply to Executive or CTI, as well as all common law rights
and claims, such as breach of contract, express or implied, tort, whether
negligent or intentional, wrongful discharge, defamation, infliction of
emotional distress, and any claim for fraud, omission or misrepresentation.
Executive also states and agrees that she has not experienced any illness,
injury, or disability relating to or arising in whole or in part from her
employment with CTI that is or may be compensable under the worker's
compensation laws of any state, and that she will not file a worker's
compensation claim asserting the existence of any such illness, injury, or
disability.

4.   In consideration for executing this Legal Release, Executive shall receive:

     a.  Her regular compensation through the end of September 2000.

     b.  The balance of her remaining salary on her employment agreement, which
the parties agree equals $415,917.00, plus the balance of her Officer's
Allowance, which the parties agree equals $34,500.00;

                                       1
<PAGE>

     c. Her projected Annual Bonus for 2000, which the parties agree equals
$208,845.00;

     d. A Lock-up Release Agreement of Executive's Stock Options of up to 30,930
shares of common stock of CoorsTek, Inc.  The Lock-up Release agreed to by the
parties as well as the sock option vesting schedule are attached as Exhibit A.

     e. Five weeks of vacation based on her salary of $217,000.00 per year;

     f. Reimbursement of her attorney fees paid to Roman, Benezra & Culver,
L.L.C., without the right to inspect the same or challenge them on the grounds
of reasonableness, of up to $7,500.00;

     g. Her medical and dental premiums for one year in an amount of $5,460.00;

     h. Reimbursement for outplacement services. Specifically, CTI shall pay
Executive up to $25,000 in outplacement services provided to Executive by a
third-party outplacement consultant or consulting service.  Executive shall
reasonably select the outplacement provider and contract for outplacement
services, and shall forward invoices for outplacement services to CTI, which
shall promptly pay the invoiced amount directly to the outplacement provider;

     i. The right to keep her lap top computer; and

     j. A letter of recommendation from Joseph Coors, Jr. The agreed upon letter
of recomm endation is attached as Exhibit B.

5.   Executive agrees that the Benefit that she is accepting by signing this
Agreement has value to her, that she would not be entitled to the Benefit
without signing this Agreement, that she will receive the Benefit in exchange
for the benefit that will accrue to CTI from Executive's execution of this
Agreement, and that when CTI pays her the Benefit, CTI will withhold all
applicable federal, state and local taxes.

6.   Executive agrees that the only benefit that she is to receive by signing
this Agreement is the Benefit, and that in signing this Agreement she did not
rely on any information, oral or written, from anyone other than the information
set forth in this Agreement and the advice, if any, of Executive's counsel.

7.   This Agreement is to be interpreted in the broadest possible manner in
favor of forever resolving all disputes between Executive and CoorsTek, Inc.,
including its officers, directors, employees, and agents.  Executive agrees
that, if she brings any kind of legal claim against CTI that she has given up by
signing this Agreement, then she will be violating this Agreement and therefore
must pay all legal fees, other costs and expenses incurred by CTI in defending
against all such claims.

8.   Executive represents that she has not previously assigned or transferred
any of the legal rights and claims that she has given up by signing this
Agreement, and agrees that this Agreement also binds all persons who might
assert a legal right or claim on her behalf, such as her heirs, personal
representatives and assigns, now and in the future.

                                       2

9.   Executive agrees that CTI will not provide her with recall rights or any
other right to future employment at CTI or any affiliate, and that Executive
will not be given any preference or priority with respect to any future job
openings that may arise.  Executive also agrees that if she later is rehired by
CTI, CTI may in its sole discretion require Executive to return to CTI all or a
portion of the Benefit as a condition of the rehiring.

10.  Executive understands she is giving up her rights to sue CTI for age
discrimination by signing this Agreement. Executive understands that she has the
right to take twenty-one days to decide whether or not to sign this Agreement
and give up her legal rights. If Executive signed before the expiration of
twenty-one days, she was not required to do so and could have taken then entire
twenty-one days to consider this Agreement. Furthermore, Executive also has the
right to revoke this Agreement within seven days after signing it, insofar as
the Agreement gives up her right to sue for age discrimination. The revocation
must be in writing addressed to Janet Comerford, facsimile no. (970) 257-3855.
The revocation shall only apply to her rights under ADEA, and Executive will,
therefore, not be entitled to the annual bonus of $208,845.00 described in
paragraph 4(c) of this Agreement, which is separate consideration for waiving
her right to sue CTI for age discrimination.

11.  Executive will receive all compensation owed under this Agreement within
three (3) days following the expiration of the revocation.  However, Executive
will receive an executed copy of the Lock-up Release within one (1) day of her
execution of this Agreement.

12.  Executive agrees that: (a) this Agreement constitutes the entire agreement
between Executive and CTI concerning severance compensation and the other
subjects raised therein, without regard to any other oral or written information
that Executive may have received about this Agreement; (b) if any part of this
Agreement is declared to be unenforceable, all other provisions of this
Agreement shall remain enforceable; and (c) this Agreement shall be governed by
federal law and by the internal law of the State of Colorado, irrespective of
the choice of law rules of any jurisdiction. Executive further agrees that this
Agreement is in full and complete satisfaction of her contract rights under the
Executive Employment Agreement.

that its Committed Sum under the Revolver Facility shall be increased to the
amount corresponding to the Revolver Facility set forth opposite its name on
Replacement Schedule 2.1 attached hereto. Accordingly, each Revolver Lender's
Commitment Percentage shall be recalculated to reflect the new proportionate
share of the revised Revolver Commitment as stated on Replacement Schedule 2.1.

(a)       Furthermore, to the extent any Revolver Principal Debt is outstanding
on the Restatement Effective Date (excluding any Revolver Loans made on such
date), then on such date, each Increasing Lender shall pay to Administrative
Agent (for ratable distribution to the other Revolver Lenders) an amount equal
to its Commitment Percentage of the Revolver Principal Debt then outstanding,
which is deemed assumed and purchased from the other Revolver Lenders. All such
payments shall reduce the Revolver Principal Debt owed to each Revolver Lender
receiving such payments and shall represent a Borrowing under the Revolver
Facility by Borrower from the appropriate Increasing Lender. On and after the
Restatement Effective Date, the Increasing Lenders shall be entitled to share
ratably in interest accruing in accordance with the Loan Documents.
(b)
(c)       To the extent a payment contemplated in Paragraph 2(b), if any, occurs
on a date other than the last day of any Interest Period for any outstanding
Eurodollar Rate Borrowing, Borrower agrees to pay to each Lender (upon the
request of each such Lender) the amounts required by Section 5.5(a) in
connection therewith.
(d)
2.        Conditions Precedent.   Notwithstanding any contrary provision, this
          --------------------
Agreement is not effective until the date upon which Administrative Agent
receives all of the following (each in form and substance acceptable to
Administrative Agent):
3.
(a)       This Agreement.  Counterparts of this Agreement (together with all
          --------------
Schedules and Exhibits) executed by Borrower, Administrative Agent, Required
Lenders, Increasing Lenders, and Guarantors;

(b)
(c)       Notes.  With respect to any Increasing Lender and only to the extent
          ------
requested pursuant to Section 3.1(b), a replacement Revolver Note substantially
in the form of Exhibit A-1 payable to such requesting Increasing Lender;
(d)
(e)       Officers' Certificates. Officers' Certificates of Borrower and of each
          ----------------------
Guarantor (i) certifying that there have been no changes to its Articles of
Incorporation and Bylaws since the date of their last certification pursuant to
the Loan Documents, (ii) confirming the continued incumbency of its officers
since the date of their last certification pursuant to the Loan Documents, and
(iii) certifying copies of resolutions duly adopted by its Board of Directors
approving this Agreement and the other Loan Documents and authorizing the
transactions contemplated in such Loan Documents;
(f)
(g)       Payment of Fees and Expenses.  Payment of all unpaid fees and expenses
          ----------------------------
payable on or prior to the date hereof to Administrative Agent, including,
without limitation, fees and expenses of counsel pursuant to Paragraph 5(c).
(h)
(i)       Opinion. Opinion of Borrower's counsel addressed to Administrative
          -------
Agent and Lenders, in form and substance satisfactory to Administrative Agent.
(j)
(k)       Other Documents. Such other agreements, documents, instruments,
          ---------------
opinions, certificates, and evidences as Administrative Agent may reasonably
request. Administrative Agent shall, upon request of Borrower, confirm to
Borrower that it has received all such items so requested.
(l)
4.        Waiver.
          ------
5.
(a)       Borrower's Waiver Request. Borrower has informed Administrative Agent
          -------------------------
that it has formed three new Domestic Subsidiaries (the "Subject Domestic
Subsidiaries") as set forth on the attached Replacement Schedule 8.3 and has
transferred certain assets of one or more previously existing Domestic
Subsidiaries to one or more of the Subject Domestic Subsidiaries, but, in
connection therewith, has inadvertently failed to comply with the provisions of
Section 9.16 (Permitted Acquisitions, Subsidiary Guaranties, and Collateral
Documents), Section 9.20 (Loans, Advances, and Investments), and Section 9.23
(Sale of Assets) in a timely manner (the "Subject Noncompliance"). Borrower has
requested that Required Lenders waive the Subject Noncompliance. Required
Lenders are willing to grant and agree to such waver, subject to and upon the
terms and conditions set forth in Paragraph 4.
(b)
(c)       Waiver and Conditions. Required Lenders waive any Default or Potential
          ---------------------
Default that may exist or arise solely as a result of the Subject Noncompliance
and agree that Lenders will not exercise their Rights under the Loan Documents
solely as a result of the Subject Noncompliance; provided, however, that, the
waiver herein granted is expressly conditioned upon the requirement that
Borrower shall have satisfied the requirements of Sections 9.16, 9.20, and 9.23
no later than January 26, 2001. Except as expressly stated, this Paragraph 4 is
not a waiver of existing or future Defaults or Potential Defaults or a waiver of
Administrative Agent's or any Lender's Rights to insist upon compliance by all
relevant parties with each Loan Document. The failure of Borrower to comply with
the conditions or limitations set forth in this Paragraph 4 shall constitute a
Default entitling Lenders to exercise their respective Rights under the Loan
Documents. The waiver under this Paragraph 4 is expressly subject to the
condition that no Default or Potential Default now exists or will arise as a
result of the formation of the Subject Domestic Subsidiaries, other than
Defaults or Potential Defaults expressly waived in accordance with the Loan
Documents.
