Exhibit 10.2

                            CALGON CARBON CORPORATION

                          1999 NON-EMPLOYEE DIRECTORS'
                             PHANTOM STOCK UNIT PLAN
                      (AS AMENDED THROUGH FEBRUARY 6, 2001)

                  The purposes of the 1999 Non-Employee Directors' Phantom Stock
Unit Plan (the "Plan") are to promote the long-term success of Calgon Carbon
Corporation (the "Company") and its Subsidiaries by creating a mutuality of
interests between the non-employee Directors and the stockholders of the
Company, to provide an additional inducement for such Directors to remain with
the Company and to provide a means through which the Company may attract able
persons to serve as Directors of the Company.

                                    SECTION 1

                                 ADMINISTRATION

                  The Plan shall be administered the Board of Directors of the
Company (the "Board"). The Board may delegate some or all of its duties
hereunder to a Committee appointed by the Board. The Board shall interpret the
Plan and prescribe such rules, regulations and procedures in connection with the
operations of the Plan as it shall deem to be necessary and advisable for the
administration of the Plan consistent with the purposes of the Plan. All
questions of interpretation and application of the Plan, or as to Units (as
defined in Section 3 below) granted under the Plan, shall be subject to the
determination of the Board, which shall be final and binding.

                  Notwithstanding the above, the selection of the Directors to
whom Units are to be granted, the timing of such grants, the number of Units to
be granted (including the dollar value used to calculate the Units to be
granted), the time at which the Units may be exercised and the term of any Units
shall be as hereinafter provided, and the Board shall have no discretion as to
such matters unless and until the Plan is amended in accordance with the Plan.

                                    SECTION 2

                         UNITS AVAILABLE UNDER THE PLAN

                  The aggregate number of Units (as defined in Section 3 below)
which may be granted under the Plan is 1,000,000 Units, subject to adjustment
and substitution as set forth in Section 7. If any Units granted under the Plan
are cancelled by mutual consent or terminate or expire for any reason without
having been exercised in full, such number of Units shall again be available for
purposes of the Plan.


                                    SECTION 3

                  ELIGIBILITY AND GRANT OF PHANTOM STOCK UNITS

                  On the first business day following the day of each annual
meeting of the stockholders of the Company, each person who is then a member of
the Board and who is not then an employee of the Company or any of its
subsidiaries (a "non-employee Director") shall automatically and without further
action by the Board be granted a number of phantom stock units (a "Unit" or
"Units") equal to $7,000 divided by the Fair Market Value (as defined in Section
5(H) below) of a share of Common Stock, $.01 par value, of the Company on such
date, with fractional interests rounded up to the next whole share.

                  On the day that each person who was not prior thereto a member
of the Board and who is not then an employee of the Company or any of its
subsidiaries is elected to the Board, other than such person being elected at an
Annual Meeting of the Company (the "Join Date"), such person shall automatically
and without further action by the Board by granted a number of Units equal to
the Prorated Amount (as defined below) divided by the Fair Market Value of a
share of Common Stock of the Company on such Join Date, with fractional
interests rounded up to the next whole share. "Prorated Amount" shall mean (i)
$1,750 if the Join Date is in January, February, March or April, (ii) $3,500 if
the Join Date is in October, November or December; (iii) $5,250 if the Join Date
is in July, August or September; and (iv) $7,000 if the Join Date is in May or
June.

                                    SECTION 4

                                 VALUE OF UNITS

                  A Unit shall evidence the right to receive an amount equal to
the Fair Market Value (as defined in Section 5(H) below) of a share of Common
Stock as of a specified date or as of the date of occurrence of a specified
event.

                                    SECTION 5

                          TERMS AND CONDITIONS OF UNITS

                  Units granted under the Plan shall be subject to the following
terms and conditions:

                  (A)  Units shall fully vest on the date of grant.

                                      - 2 -


                  (B)  Upon exercise of a Unit by a grantee, such grantee shall
         be entitled to be paid cash equal to the Fair Market Value (as defined
         in Section 5(H) below) of a share of Common Stock on the date of
         exercise, multiplied by the number of Units exercised. All Unit
         exercise shall be settled in cash and not in Common Stock of the
         Company. Amounts due upon any exercises of Units shall be paid by the
         Company in full on or before 30 days from the date of exercise.

                  (C)  Units shall only be exercisable, and shall automatically
         be exercised, upon a non-employee Director's termination from service
         on the Board, whether due to death, disability, removal, resignation,
         failure to stand for re-election, failure to be re-elected or
         otherwise.

                  (D)  All calculations to be performed under this Plan shall be
         done by the Board or its designees, in its discretion, whose
         determination shall be final and binding, absent manifest error.

                  (E)  Except as may be required by law, the grantee shall not
         have the right to, directly or indirectly, alienate, assign, transfer,
         pledge, anticipate or encumber (except upon death, by Will or if the
         grantee dies intestate, by the laws of descent and distribution of the
         state of domicile of the grantee at the time of death) any amount that
         is or may be payable hereunder, including in respect of any liability
         of a grantee for alimony or other payments for the support of a spouse,
         former spouse, child or other dependent, prior to actually being
         received by the grantee hereunder, nor shall the grantee's rights to
         payments under the Plan be subject in any manner to anticipation,
         alienation, sale, transfer, assignment, pledge, encumbrance,
         attachment, or garnishment by creditors of the grantee or to the debts,
         contracts, liabilities, engagements, or torts of the grantee, or
         transfer by operation of law in the event of bankruptcy or insolvency
         of the grantee, or any legal process. All Units shall be exercisable
         during the lifetime of the grantee only by the grantee.

                  (F)  All Units shall be confirmed by an agreement, or an
         amendment thereto, which shall be executed on behalf of the Company by
         the Chief Executive Officer (if other than the President), the
         President or any Vice President and by the grantee. The provisions of
         such agreements, or amendments thereto, need not be identical.

                                      - 3 -


                  (G)  The obligation of the Company to grant or honor the
         exercise of Units under the Plan shall be subject to (i) the
         effectiveness of a registration statement under the Securities Act of
         1933, as amended, with respect to such shares, if deemed necessary or
         appropriate by counsel for the Company, and (ii) all other applicable
         laws, regulations, rules and orders which may then be in effect.

                  (H)  Fair market value of the Common Stock shall be the mean
         between the following prices, as applicable, for the date as of which
         fair market value is to be determined as quoted in The Wall Street
                                                            --- ---- ------
         Journal (or in such other reliable publication as the Committee, in its
         -------
         discretion, may determine to rely upon): (a) if the Common Stock is
         listed on the New York Stock Exchange, the highest and lowest sales
         prices per share of the Common Stock as quoted in the NYSE-Composite
         Transactions listing for such date, (b) if the Common Stock is not
         listed on such exchange, the highest and lowest sales prices per share
         of Common Stock for such date on (or on any composite index including)
         the principal United States securities exchange registered under the
         Securities Exchange Act of 1934 (the "1934 Act") on which the Common
         Stock is listed, or (c) if the Common Stock is not listed on any such
         exchange, the highest and lowest sales prices per share of the Common
         Stock for such date on the National Association of Securities Dealers
         Automated Quotations System or any successor system then in use
         ("NASDAQ"). If there are no such sale price quotations for the date as
         of which fair market value is to be determined but there are such sale
         price quotations within a reasonable period both before and after such
         date, then fair market value shall be determined by taking a weighted
         average of the means between the highest and lowest sales prices per
         share of the Common Stock as so quoted on the nearest date before and
         the nearest date after the date as of which fair market value is to be
         determined. The average should be weighted inversely by the respective
         numbers of trading days between the selling dates and the date as of
         which fair market value is to be determined. If there are no such sale
         price quotations on or within a reasonable period both before and after
         the date as of which fair market value is to be determined, then fair
         market value of the Common Stock shall be the mean between the bona
         fide bid and asked prices per share of Common Stock as so quoted for
         such date on NASDAQ, or if none, the weighted average of the means
         between such bona fide bid and asked prices on the nearest trading date
         before and the nearest trading date after the date as of which fair
         market value is to be determined, if both such dates are within a
         reasonable period. The average is to be determined in the manner
         described above in this Section 5(H). If the fair market value of the
         Common Stock

                                      - 4 -


         cannot be determined on the basis previously set forth in this
         Section 5(H) for the date as of which fair market value is to be
         determined, the Committee shall in good faith determine the fair market
         value of the Common Stock on such date. Fair market value shall be
         determined without regard to any restriction other than a restriction
         which, by its terms, will never lapse.

                  (I)  If Units are outstanding as of the record date for
         determination of the stockholders of the Company entitled to receive a
         cash dividend on its outstanding shares of Common Stock, on the date of
         payment of the dividend or distribution to holders of the Common Stock,
         each Unit Account shall be credited with a number of shares of Common
         Stock (including fractional shares) equal to the number of shares of
         Common Stock that had been credited to such Unit Account on the date
         fixed for determining the stockholders entitled to receive such
         dividend or distribution multiplied by the amount of the dividend or
         distribution paid per share of Common Stock divided by the Fair Market
         Value of one share of the Common Stock, as defined in Section 5(H)
         hereof, on the date on which the dividend or distribution is paid. If
         the dividend or distribution is not paid in cash but is paid in
         property other than Common Stock, the amount of the dividend or
         distribution shall equal the fair market value of the property on the
         date on which the dividend or distribution is paid.

         Subject to the foregoing provisions of this Section 5 and the other
provisions of the Plan, Units granted under the Plan shall be subject to such
restrictions and other terms and conditions, if any, as shall be determined, in
its discretion, by the Board and set forth in the agreement referred to in
Section 5(F), or an amendment thereto.

                                    SECTION 6
                                 NATURE OF UNITS

                  Units are not shares of the Company. Units do not have any
voting or liquidation rights. A grantee will have no rights of a stockholder of
the Company with respect to any Units. Except as provided in Section 7 below, a
grantee shall have no rights by reason of any issue by the Company of stock of
any class or securities convertible into stock of any class, any subdivision or
consolidation of shares of stock of any class, the payment of any stock dividend
or any other increase or decrease in the number of shares of stock of any class.

         The Plan constitutes a mere promise by the Company to make payments in
the future. The Company's obligations under the Plan

                                      - 5 -


shall be unfunded and unsecured promises to pay. The Company shall not be
obligated under any circumstance to fund its financial obligations under the
Plan. The Company may, in its discretion, set aside funds in a trust, in
brokerage accounts, or in other vehicles, subject to the claims of its
creditors, in order to assist it in meeting its obligations under the Plan, if
such arrangement will not cause the Plan to be considered a funded deferred
compensation plan under ERISA, or the Internal Revenue Code of 1986, as amended
(the "Code"). To the extent that any grantee or other person acquires a right
to receive payments under the Plan, such right shall be no greater than the
right, and each such person shall at all times have the status, of a general
unsecured creditor of the Company.

                                    SECTION 7

                      ADJUSTMENT AND SUBSTITUTION OF UNITS

                  If a dividend or other distribution shall be declared upon the
Common Stock payable in shares of the Common Stock, the number of Units set
forth in Section 2 and the number of Units then held by non-employee Directors
shall be adjusted by adding thereto a number of Units equal to the number of
shares which would have been distributable on such Units if such Units were
shares outstanding on the date fixed for determining the stockholders entitled
to receive such stock dividend or distribution.

                  In the event that the outstanding Common Stock shall be
changed in number, class or character by reason of any split-up, change of par
value, stock dividend, combination or reclassification of shares, merger,
consolidation or other corporate change, or shall be changed in value by reason
of any spin-off, dividend in partial liquidation or other special distribution,
the Board shall make such changes as it may deem equitable in outstanding Units
awarded pursuant to the Plan and the number and character of Units available for
future awards.

                                    SECTION 8

                            EFFECT OF THE PLAN ON THE
                       RIGHTS OF COMPANY AND STOCKHOLDERS

                  Nothing in the Plan, in any Units granted under the Plan, or
in any Unit agreement shall confer any right to any person to continue as a
Director of the Company or interfere in any way with the rights of the
stockholders of the Company or the Board of Directors to elect and remove
Directors.

                                      - 6 -


                                    SECTION 9

                            AMENDMENT AND TERMINATION

                  The right to alter and amend the Plan at any time and from
time to time and the right to revoke or terminate the Plan are hereby
specifically reserved to the Board; provided, that no amendment of the Plan
shall (a) be made without stockholder approval if stockholder approval of the
amendment is at the time required for Units under the Plan to qualify for the
exemption from Section 16(b) of the 1934 Act provided by Rule 16b-3 or by the
rules of the NASDAQ National Market System or any stock exchange on which the
Common Stock may then be listed, (b) amend more than once every six months the
provisions of the Plan relating to the selection of the Directors to whom Units
are to be granted, the timing of such grants, the number of Units to be granted
(including the dollar value used to calculate the Units to be granted), the time
at which the Units may be exercised and the term of any Units other than to
comport with changes in the Code or the rules and regulations thereunder or (c)
otherwise amend the Plan in any manner that would cause Units under the Plan not
to qualify for the exemption provided by Rule 16b-3. No alteration, amendment,
revocation or termination of the Plan shall, without the written consent of the
holder of Units theretofore granted under the Plan, adversely affect the rights
of such holder with respect thereto.

                  Notwithstanding anything contained in the preceding paragraph
or any other provision of the Plan or any Unit agreement, the Board shall have
the power to amend the Plan in any manner deemed necessary or advisable for
Units granted under the Plan to qualify for the exemption provided by Rule 16b-3
(or any successor rule relating to exemption from Section 16(b) of the 1934
Act), and any such amendment shall, to the extent deemed necessary or advisable
by the Board, be applicable to any outstanding Units theretofore granted under
the Plan notwithstanding any contrary provisions contained in any Unit
agreement. In the event of any such amendment to the Plan, the holder of any
Unit outstanding under the Plan shall, upon request of the Board and as a
condition to the exercisability of such Unit, execute a conforming amendment in
the form prescribed by the Board to the Unit agreement referred to in Section
5(F) within such reasonable time as the Board shall specify in such request.

                                   SECTION 10

                                  GOVERNING LAW

                  The Plan shall be governed by and interpreted in accordance
with the laws of the Commonwealth of Pennsylvania.

                                   SECTION 11

                       EFFECTIVE DATE AND DURATION OF PLAN

                  The effective date and date of adoption of the Plan shall be
March 15, 1999. No Units may be granted under the Plan subsequent to March 14,
2009.
