                                       OF
                            SCC COMMUNICATIONS CORP.
                                TO BE DESIGNATED
                            SERIES A PREFERRED STOCK

     SCC Communications Corp., a Delaware corporation (the "Corporation"),
pursuant to authority conferred on the Board of Directors of the Corporation by
the Certificate of Incorporation and in accordance with the provisions of
Section 151 of the General Corporation Law of the State of Delaware, certifies
that the Board of Directors of the Corporation, at a meeting duly called and
held, at which a quorum was present and acting throughout, duly adopted the
following resolution:

RESOLVED: That, pursuant to the authority expressly granted to and vested in the
          Board of Directors of the Corporation in accordance with the
          provisions of its Certificate of Incorporation, a series of Preferred
          Stock of the Corporation be and hereby is established, consisting of
          [   ](1) shares, to be designated "Series A Preferred Stock"; that the
          Board of Directors be and hereby is authorized to issue such shares of
          Series A Preferred Stock from time to time and for such consideration
          and on such terms as the Board of Directors shall determine; and that,
          subject to the limitations provided by law and by the Certificate of
          Incorporation, the powers, designations, preferences and relative,
          participating, optional or other special rights of, and the
          qualifications, limitations or restrictions upon, the Series A
          Preferred Stock shall be as follows:

1.   NO DIVIDENDS

     The holders of shares of Series A Preferred Stock shall not be entitled to
receive dividends.

2.   LIQUIDATION, DISSOLUTION OR WINDING UP

     (a) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of shares of Series
A Preferred Stock then outstanding shall be entitled to be paid out of the
assets of the Corporation available for distribution to its stockholders,
before any payment shall be made to the holders of Common Stock or any other
class or series of stock ranking on liquidation junior to the Series A
Preferred Stock (such Common Stock and other stock being collectively
referred to as "Junior Stock") by reason of their ownership thereof, an
amount equal to $1,000.00 per share (subject to appropriate adjustment in the
event of any stock dividend, stock split, combination or other similar
recapitalization affecting such shares). If upon any such liquidation,
dissolution or winding up of the Corporation the remaining assets of the
Corporation available for distribution to its stockholders shall be
insufficient to pay the holders of shares of Series A Preferred Stock the
full amount to which they shall be entitled, the holders of shares of Series
A Preferred Stock and any class or series of stock ranking on liquidation on
a parity with the Series A Preferred Stock shall share ratably in any
distribution of the remaining assets and funds of the Corporation in
proportion to the respective amounts which would otherwise be payable in
respect of the shares held by them upon such distribution if all amounts
payable on or with respect to such shares were paid in full.

     (b) After the payment of all preferential amounts required to be paid to
the holders of Series A Preferred Stock and any other class or series of
stock of the Corporation ranking on liquidation on a parity with the Series A
Preferred Stock, upon the dissolution, liquidation or winding up of the
Corporation, the

the procedure set forth in SCHEDULE 2.3(c).

<PAGE>

holders of shares of Junior Stock then outstanding shall be entitled to receive
the remaining assets and funds of the Corporation available for distribution to
its stockholders.

     (c) A consolidation or merger of the Corporation with or into another
corporation or entity, or a sale of all or substantially all of the assets of
the Corporation, shall not be regarded as a liquidation, dissolution or
winding up of the Corporation within the meaning of this Section 2.

     (d) The Corporation may not liquidate, dissolve or wind up if the assets
of the Corporation then available for distribution to its stockholders shall
be insufficient to pay the holders of shares of Series A Preferred Stock the
full amount to which they shall be entitled upon such liquidation,
dissolution or winding up under this Section 2, without the prior written
approval of the holders of a majority of the then-outstanding shares of
Series A Preferred Stock.

3.   VOTING

     (a) Holders of Series A Preferred Stock shall not be entitled to vote on
any matter except as provided by law or by the provisions of Subsection 3(b)
below.

     (b) The Corporation shall not amend, alter or repeal the preferences,
special rights or other powers of the Series A Preferred Stock so as to
affect adversely the Series A Preferred Stock, without the written consent or
affirmative vote of the holders of a majority of the then-outstanding shares
of Series A Preferred Stock, given in writing or by vote at a meeting,
consenting or voting (as the case may be) separately as a class. For this
purpose, without limiting the generality of the foregoing, (i) the
authorization of any shares of capital stock with preference or priority over
the Series A Preferred Stock as to the right to receive amounts distributable
upon liquidation, dissolution or winding up of the Corporation shall be
deemed to affect adversely the Series A Preferred Stock, (ii) the
authorization of any shares of capital stock on a parity with Series A
Preferred Stock as to the right to receive amounts distributable upon
liquidation, dissolution or winding up of the Corporation shall not be deemed
to affect adversely the Series A Preferred Stock, and (iii) an increase or
decrease (but not below the number of shares then outstanding) in the number
of authorized shares of Series A Preferred Stock shall not be deemed to
affect adversely the Series A Preferred Stock

     (c) So long as at least 1,000 shares of Series A Preferred Stock shall
be outstanding, the Corporation shall not, without first obtaining the
affirmative vote or written consent of the holders of not less than a
majority of the then-outstanding shares of Series A Preferred Stock:

         (i)   pay or declare any dividend or distribution on any shares of its
               capital stock (except dividends payable solely in shares of
               Common Stock), or apply any of its assets to the redemption,
               retirement, purchase or acquisition, directly or indirectly,
               through subsidiaries or otherwise, of any shares of its capital
               stock (other than repurchase of Common Stock at cost upon
               termination of employment or service);

         (ii)  sell, lease or otherwise dispose of all or a substantially all of
               its assets or properties; or

         (iii) voluntarily liquidate or dissolve.

     (a) MANDATORY SCHEDULED REDEMPTION

         (i)   The Corporation will, subject to the conditions set forth below,

     stock dividend, stock split, combination or other similar recapitalization
     affecting such shares (the "Redemption Price"), the following aggregate

     (b) MANDATORY REDEMPTION UPON PUBLIC OFFERING

         (i)   The Corporation will, subject to the conditions set forth below,
     on a date (a "Public Offering Redemption Date") as soon as reasonably
     practicable following consummation of an underwritten public offering by
     the Corporation (either by itself or with selling stockholders) of shares
     of the Corporation's common stock (a "Public Offering"), redeem from the
     holders of Series A Preferred Stock, at the Redemption Price, an aggregate
     number of shares of Series A Preferred Stock equal to the quotient of
     (A) 25% of the amount of gross proceeds to the Corporation (net of
     underwriting discounts and commission), if any, from such Public Offering,
     divided by (B) the Redemption Price.

         (ii)  If a mandatory redemption is effected pursuant to this
     Section 4(b), the number of shares of Series A Preferred Stock required to
     be redeemed at the next Mandatory Redemption Date following such redemption
     shall be reduced by the number of shares so redeemed (and at the next
     succeeding Mandatory Redemption Date or Dates, to the extent the number of
     shares redeemed pursuant to this Section 4(b) exceeds the number of shares
     required to be redeemed on the next Mandatory Redemption Date or Dates).

     (c) OPTIONAL REDEMPTION

     The Corporation may, at its option, in whole or in part, redeem shares
of Series A Preferred Stock at a price equal to the Redemption Price at any
time. A date on which such a redemption occurs shall be referred to herein as
an "Optional Redemption Date."

     (d) REDEMPTION PROCEDURES

         (i)   If the Corporation shall redeem less than all of the
     then-outstanding shares of Series A Preferred Stock on a Mandatory
     Redemption Date, Public Offering Redemption Date or Optional Redemption
     Date (each a "Redemption Date") pursuant to Section 4(a), (b) or (c) above,
     the Corporation shall redeem shares from each holder of Series A Preferred
     Stock based on such holder's pro rata portion (based on the total number of
     shares of Series A Preferred Stock held by such holder), as of such
     Redemption Date, of the aggregate number of the shares of Series A
     Preferred Stock being redeemed.

         (ii)  The Corporation shall provide notice of each redemption pursuant
     to Section 4(a), (b) or (c) above, specifying the time, manner and place of
     redemption and the Redemption Price (a "Redemption Notice"), by first class
     or registered mail, postage prepaid, to each holder of record of Series A
     Preferred Stock at the address for such holder last shown on the records of
     the transfer agent therefor (or the records of the Corporation, if it
     serves as its own transfer agent), not less than 45 days

                                     - 3 -
<PAGE>

     prior to the applicable Redemption Date. Except as provided in
     Section 4(d)(iii) below, each holder shall surrender to the Corporation on
     the applicable Redemption Date the certificate or certificates representing
     the shares to be redeemed on such date, in the manner and at the place
     designated in the Redemption Notice. Thereupon, the Redemption Price shall
     be paid to the order of each such holder and each certificate surrendered
     for redemption shall be canceled. In the event less than all the shares of
     Series A Preferred Stock represented by a certificate are redeemed, a new
     certificate representing the unredeemed shares of Series A Preferred Stock
     shall be issued forthwith.

         (iii) If the funds of the Corporation legally available for redemption
     of Series A Preferred Stock on any Mandatory Redemption Date or Public
     Offering Redemption Date are insufficient to redeem the number of shares of
     Series A Preferred Stock required under Section 4(a) or 4(b), as the case
     may be, to be redeemed on such date, those funds that are legally available
     will be used to redeem the maximum possible number of such shares of
     Series A Preferred Stock ratably on the basis of the number of shares of
     Series A Preferred Stock that would be redeemed on such date if the funds
     of the Corporation legally available therefor had been sufficient to redeem
     all shares of Series A Preferred Stock required to be redeemed on such
     date. At any time thereafter when additional funds of the Corporation
     become legally available for the redemption of Series A Preferred Stock,
     such funds will be used, at the end of the next succeeding fiscal quarter,
     to redeem the balance of the shares which the Corporation was theretofore
     obligated to redeem, ratably on the basis set forth in the preceding
     sentence.

         (iv)  Unless there shall have been a failure to pay the Redemption
     Price, on the Redemption Date all rights of the holder of each share
     redeemed on such date as a stockholder of the Corporation by reason of the
     ownership of such share will cease, except the right to receive the
     Redemption Price of such share, without interest, upon presentation and
     surrender of the certificate representing such share, and such share will
     not from and after such Redemption Date be deemed to be outstanding.

         (v)   Any Series A Preferred Stock redeemed pursuant to this Section 4
     will be canceled and will not under any circumstances be reissued, sold or
     transferred and the Corporation may from time to time take such appropriate
     action as may be necessary to reduce the authorized Series A Preferred
     Stock accordingly.

5.   WAIVER

     Any of the rights of the holders of Series A Preferred Stock set forth
herein may be waived by the affirmative consent or vote of the holders of a
majority of the shares of Series A Preferred Stock then outstanding.

     IN WITNESS WHEREOF, the Corporation has caused this Certificate of
Designation to be signed by its President this ____ day of _______, ______.

                THIRD AMENDMENT TO CREDIT AND SECURITY AGREEMENT
                                       AND
                 FIRST AMENDMENT TO COLLATERAL PLEDGE AGREEMENT

     This Amendment, dated as of March 30, 2001, is made by and among LUMINANT
WORLDWIDE CORPORATION, a Delaware corporation, LWC OPERATING CORP., a Delaware
corporation, LWC MANAGEMENT CORP., a Delaware corporation, POTOMAC I HOLDINGS,
INC., a Delaware corporation, MULTIMEDIA I HOLDINGS, INC., a Delaware

                                    RECITALS

     The Borrowers and the Lender have entered into a Credit and Security
Agreement dated as of April 5, 2000 as amended by a First Amendment to Credit
and Security Agreement dated as of August 31, 2000, a letter amendment dated as
of September 21, 2000, and a Second Amendment to Credit and Security Agreement
dated as of December 28, 2000 (as amended to date, the "Credit Agreement").

     Parent Borrower executed and delivered the Pledge Agreement on December 28,
2000, thereby subjecting its general brokerage account no. 12624854, to which
the Pledged Securities had been credited, to a security interest in favor of the
Lender. Contemporaneously, with the consent of Parent Borrower, the Lender
notified Wells Fargo Brokerage Services, LLC (the "Brokerage") that the account
was subject to the Lender's security interest, and the Brokerage agreed to
comply with buy, sell and withdrawal orders initiated by the Lenderand permitted
under the terms of the Pledge Agreement.

     The Borrowers have requested that the Lender agree to waive certain Events
of Default and that certain amendments be made to the Credit Agreement. The
Lender wishes to clarify and confirm certain matters in connection with the
Pledge Agreement. Accordingly, the parties have agreed to amend the Credit
Agreement and the Pledge Agreement in the manner set forth herein.

     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements herein contained, the receipt and sufficiency of which
are hereby acknowledged, it is agreed as follows:

          1. DEFINED TERMS. Capitalized terms used in this Amendment which are
     defined

                                      -20-
<PAGE>

     in the Credit Agreement shall have the same meanings as defined therein,
     unless otherwise defined herein. In addition, Section 1.1 of the Credit
     Agreement is amended by adding or amending, as the case may be, the
     following definitions:

          "'Fixed Charge Coverage' means as of any date, EBITDA LESS the sum of
     (a) principal payments on Permitted Indebtedness, (b) unfinanced Capital
     Expenditures, (c) cash payments of Contingent Consideration, (d) reductions
     in the Borrowers' reserves for bad debt, and (e) collections with respect
     to accounts receivable charged off in prior periods, in each case, for the
     calendar year-to-date period ending on such date on a consolidated basis."

          "'Permitted Indebtedness' means indebtedness permitted under Section
     7.2."

          "'Pledged Securities' means those Qualified Pledged Securities and
     other securities owned by certain of the Borrowers, subject to the Pledge
     Agreement."

          "'Qualified Pledged Securities' means any securities owned by any
     Borrower that evidence obligations of the United States government or
     securities owned by the Borrowers that are rated "A-1" by Standard & Poors
     Corporation or "P-1" by Moody's Investors Service, and are pledged to the
     Lender under the Pledge Agreement."

          2. LANDLORD LETTER OF CREDIT. Wells Fargo Bank, National Association
     ("Wells Fargo Bank") has issued Letter of Credit No. NZS337627, dated
     November 12, 1999, in favor of 114 West 26th Street Associates, L.P. and
     for the account of Parent Borrower (the "Existing Credit"). Parent Borrower
     has granted a security interest in its account no. 11710282 to secure the
     obligation to reimburse Wells Fargo Bank for draws under the Existing
     Credit. Parent Borrower has requested that the Lender cause an Issuer to
     issue a Letter of Credit to replace the Existing Credit (such new Letter of
     Credit being referred to herein as the "Landlord Letter of Credit"). The
     advantages to Parent Borrower will be (i) that the Landlord Letter of
     Credit can be in a lesser face amount than the Existing Credit, and (ii)
     that Parent Borrower will be able to consolidate all of its investment
     property into its account no. 12624854 maintained with the Brokerage.
     Accordingly, the Lender and Parent Borrower hereby agree to cooperate with
     one another in order to accomplish the following necessary steps as soon as
     possible, but in no event later than April 30, 2001: (A) obtain the
     agreement of 114 West 26th Street Associates, L.P. to accept the Landlord
     Letter of Credit in substitution for the Existing Credit; (B) cause an
     Issuer to issue the Landlord Letter of Credit; (C) cause Wells Fargo Bank
     to cancel the Existing Credit; and (D) transfer all of the financial assets
     in Parent Borrower's account no. 11710282 into its account no. 12624854
     maintained with the Brokerage, whereupon such assets shall be subject to
     the security interest created under the Pledge Agreement. By way of
     clarification, the Landlord Letter of Credit shall be a "Letter of Credit"
     as such term is defined in the Credit Agreement.

          3. AMENDMENTS TO PLEDGE AGREEMENT, ETC. The Pledge Agreement is hereby
     amended as follows:

     (a)  The Debtor's correct name in the heading is "Luminant Worldwide
          Corporation."

          the Secured Party is "General Brokerage Account at Wells Fargo
          Brokerage Services, LLC, titled Luminant Worldwide Corporation account
          # 12624854, together with all rights in connection with such property
          (herein called the "Collateral")."

     (c)  Section 2(a) is hereby amended in it entirety to be and read as
          follows:

                                      -21-

               "(a) Debtor will join with Secured Party in taking any action
          reasonably required by Secured Party and consistent with the terms
          herein in order to perfect the Security Interest and protect the
          rights and priorities of the Secured Party with respect to the
          Collateral."

Parent Borrower hereby confirms that the existing agreement between the Lender
and the Brokerage was made with its consent, and agrees that it will, if
requested, join with the Lender in executing any instructions to or agreements
with the Brokerage in accordance with revised section 2(a) of the Pledge
Agreement.

          4. FINANCIAL COVENANTS. Sections 6.12, 6.13, 6.14 and 7.11 of the
     Credit Agreement are hereby amended in their entirety to read as follows:

     analogous in purpose or effect to a consolidation or merger) all or

          6. EVENTS OF DEFAULT. Section 8.1 of the Credit Agreement is amended
     by deleting the word "or" at the end of subjection (n), changing the final

     replaced by Exhibit A to this Amendment.

          8. NO OTHER CHANGES. Except as explicitly amended by this Amendment,
     all of the terms and conditions of the Credit Agreement shall remain in
     full force and effect and shall apply to any advance or letter of credit
     thereunder.

          9. WAIVER OF DEFAULTS. The Borrowers are in default of Section 6.1(b)
     of the Credit Agreement which requires the Borrowers to deliver to the
     Lender certain financial reports and a compliance certificate within 30
     days after the end of each month that is not a quarter end. The Lender did
     not receive such reports and certificate for the month ended January 31,
     2001, and the Borrowers have indicated to the Lender that the reports and
     certificate for the month ended February 28, 2001, will be delivered late.
     The Lender agrees to waive these Events of Default provided it receives all
     such reports before April 30, 2001. This waiver shall be effective only in
     this specific instance and for the specific purpose for which it is given,
     and this waiver shall not entitle the Borrowers to any other or further
     waiver in any similar or other circumstances. As of the date hereof, the
     Lender has no knowledge of any Defaults or Events of Default other than the
     Events of Default expressly set forth herein.

          10. CONDITIONS PRECEDENT. This Amendment, and the waiver set forth in
     Paragraph 9 hereof, shall be effective when the Lender shall have received
     an executed original hereof, together with such other matters as the Lender
     may reasonably require; provided that Lender shall forward to Borrowers
     written confirmation when all of the conditions precedent in this paragraph
     have been satisfied.

          11. REPRESENTATIONS AND WARRANTIES. The Borrowers hereby represent and
     warrant to the Lender as follows:

          (a) The Borrowers have all requisite power and authority to execute
     this Amendment and to perform all of their obligations hereunder, and this
     Amendment has been duly executed and delivered by the Borrowers and
     constitutes the legal, valid and binding obligation of the Borrowers,
     enforceable in accordance with its terms, except as enforceability may be
     limited by applicable bankruptcy, insolvency, fraudulent conveyance,
     reorganization, moratorium or similar laws affecting creditors' rights
     generally and by general equitable principles.

          (b) The execution, delivery and performance by the Borrowers of this
     Amendment have been duly authorized by all necessary corporate or limited
     liability company action and do not (i) require any authorization, consent
     or approval by any governmental department, commission, board, bureau,
     agency or instrumentality, domestic or foreign, (ii) violate any provision
     of any law, rule or regulation or of any order, writ, injunction or decree
     presently in effect, having applicability to the Borrowers, or the articles
     of incorporation, by-laws or comparable organizational documents of the
     Borrowers, or (iii) result in a breach of or constitute a default under any
     indenture or loan or credit agreement or any other agreement, lease or
     instrument to which any Borrower is a party or by which it or its
     properties may be bound or affected

          (c) All of the representations and warranties contained in Article V
     of the Credit Agreement are correct in all material respects on and

                                      -23-
<PAGE>

     as of the date hereof as though made on and as of such date, except to the
     extent that such representations and warranties relate solely to an earlier
     date.

          12. REFERENCES. All references in the Credit Agreement to "this
     Agreement" shall be deemed to refer to the Credit Agreement as amended
     hereby; and any and all references in the Security Documents to the Credit
     Agreement shall be deemed to refer to the Credit Agreement as amended
     hereby.

          13. NO OTHER WAIVER. Except as set forth in Paragraph 9 hereof, the
     execution of this Amendment and acceptance of any documents related hereto
     shall not be deemed to be a waiver of any Default or Event of Default under
     the Credit Agreement or breach, default or event of default under any
     Security Document or other document held by the Lender, whether or not
     known to the Lender and whether or not existing on the date of this
     Amendment.

          14. RELEASE. Each Borrower hereby absolutely and unconditionally
     releases and forever discharges the Lender, and any and all participants,
     parent corporations, subsidiary corporations, affiliated corporations,
     insurers, indemnitors, successors and assigns thereof, together with all of
     the present and former directors, officers, agents and employees of any of
     the foregoing, from any and all claims, demands or causes of action of any
     kind, nature or description, whether arising in law or equity or upon
     contract or tort or under any state or federal law or otherwise, which that
     Borrower has had, now has or has made claim to have against any such person
     for or by reason of any act, omission, matter, cause or thing whatsoever
     arising from the beginning of time to and including the date of this
     Amendment, whether such claims, demands and causes of action are matured or
     unmatured or known or unknown.

          15. COSTS AND EXPENSES. The Borrowers hereby reaffirm their agreement
     under the Credit Agreement to pay or reimburse the Lender on demand for all
     costs and expenses incurred by the Lender in connection with the Credit
     Agreement, the Security Documents and all other documents contemplated
     thereby, including without limitation all reasonable fees and disbursements
     of legal counsel. Without limiting the generality of the foregoing, the
     Borrowers specifically agree to pay all reasonable fees and disbursements
     of counsel to the Lender for the services performed by such counsel in
     connection with the preparation of this Amendment and the documents and
     instruments incidental hereto. The Borrowers hereby agree that the Lender
     may, at any time or from time to time in its sole discretion and without
     further authorization by the Borrowers, make an Advance to the Borrowers
     under the Credit Agreement, or apply the proceeds of any Advance, for the
     purpose of paying any such fees, disbursements, costs and expenses.

          16. MISCELLANEOUS. This Amendment may be executed in any number of
     counterparts, each of which when so executed and delivered shall be deemed
     an original and all of which counterparts, taken together, shall constitute
     one and the same instrument.

     IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
duly executed as of the date first written above.
