         This LEASE AMENDMENT NO. 1 (this amendment) is entered into as of
December 20, 1996, by and between Computer Learning Centers, Inc., Successor to
CLC TRAINING CORPORATION, a Delaware corporation ("Tenant"), and COMMUNITY
TOWERS, LLC, a Delaware limited liability company ("Landlord") , with reference
to the following facts:

         A.   Landlord and Tenant are the current parties to that certain
Standard Office Lease, dated as of August 12, 1991, together with an Addendum to
Lease dated August 19, 1991 (said lease and said addendum together shall be
referred to as the ("Lease"), for the lease by Tenant of space in a building
located at 111 North Market Street, San Jose, California, as more particularly
described in the Lease (the "Leased Premises") .  All capitalized terms referred
to in this Amendment shall have the same meaning defined in the Lease, except
where expressly defined to the contrary in this Amendment.

         B.   Tenant has exercised its right to extend the Lease pursuant to
section 50 of the Addendum to Lease comprising a part of the Lease. 
Accordingly, the parties desire to confirm such extension of the term of the
lease and the monthly Base Rent during said extended term, upon the terms and
conditions hereinafter set forth.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants hereinafter contained, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

         1.   Confirmation.  Tenant acknowledges and agrees that: (a) Tenant is
in sole possession of the Leased Premises demised under the Lease; (b) all work,
improvements and furnishings required by Landlord under the Lease have been
completed and accepted by Tenant; (c) all free rent and any other concession
required under the Lease have been granted, used and otherwise satisfied; and
(d) it has no offset, claim, recoupment or defense against the payment of rent
and other sums and the performance of all obligations of Tenant under the tease.

         2.   Extended Term.  Tenant has exercised its right under section 50
of the Addendum to Lease comprising a part of the Lease to extend the term of
the Lease for five (5) years as provided in this Amendment.  Accordingly section
1.5 of the Lease is amended to provide that the term of the Lease is extended
for five (5) years and shall expire on December 20, 2001 (said extended term
shall be referred to herein as the "Extended Term") .  The parties acknowledge
that Tenant has no further right to extend the term of the Lease.  As a result,
sections 50 and 60 of said Addendum to Lease are hereby deleted.

              3.   Base Rent During Extended Term.  Effective December 21,
    1996, the monthly Base Rent during the Extended Term is $31,972.80, which
    includes during the Extended Term the cost for the 100 parking spaces
    provided in section 2.2 of the Lease and section 54 of said Addendum to
    Lease.  Monthly Base Rent for any partial month shall be prorated on a
    daily basis.
               
               4.  Parking.  During the Extended Term, Lessee shall continue to
    have right to use 90 spaces at the so called "Church" parking lot and 10
    spaces at the Boccardo parking lot fronting on San Pedro Street, as
    provided in section 54 of said Addendum to Lease, or in each case at
    another parking location within the radius set forth in section 54 of said
    Addendum to Lease; however such other location does not have to be in a
    facility controlled by Boccardo. The third paragraph (regarding Lessee
    option to lease up to 30 additional spaces) of section 54 of said Addendum
    to Lease is of no further force or effect.  Neither Lessee nor any of its
    officers, employees, agents, students or invitees shall have any right to
    park without cost at the Office Building Project.  Notwithstanding the
    deletion of Lessee's option to purchase up to 30 additional parking spaces
    under the third paragraph of section 54 of said Addendum, Lessor agrees to
    cooperate in good faith with Lessee in connection with Lessee's efforts to
    lease up to thirty (30) additional parking spaces at any parking facility
    within a two (2) block radius of the Building; provided, however, that (i)
    Lessee acknowledges and agrees that providing or obtaining all or any
    portion of such additional spaces is not an obligation of Lessor nor a
    condition to the performance of any obligation of Lessee,  (ii) if all or
    any number of such additional spaces are made available to Lessee, Lessee
    shall be solely responsible for all costs and expenses for such additional
    spaces, and (iii) if all or any number of such additional spaces are made
    available, it may be done on terms and conditions acceptable to Lessor in
    its good faith but sole and absolute discretion and there is no agreement,
    guaranty, warranty or requirement that such additional space will be 
    available throughout the term of the Lease, as extended hereby.

               5.   HVAC.  There currently exists a heating and air-conditioning
    unit on the ground floor of the Building that services the Leased Premises
    ("Ground Floor HVAC Unit"). At such time as Landlord shall be able to 
    provide (and shall provide) the same level of comfort presently achieved 
    using the Ground Floor HVAC Unit through use of the HVAC system available
    to the Building, Landlord shall have the right to disconnect the Ground 
    Floor HVAC Unit.

               6.   Hours of Operation.  Section 53 of the Addendum to Lease
    comprising a part of the Lease is amended to provide that Lessee's hours of
    operation shall only be as follows:


         7:00   a.m. to   11:00 p.m.     - Mondays, Wednesday and Thursday
         7:00   a.m. to   6:00  p.m.     - Tuesdays and Fridays
        10:00   a.m. to   4:00  p.rn.    - Saturdays

    execute any and all documents and agreements reasonably requested by the 
    other party to further evidence or effectuate this Amendment.

                    7.2  Successors and Assigns.  This Amendment shall be 
    binding upon and inure to the benefit of the parties hereto and their 
    successors and assigns.

                    7.3  Reaffirmation.  As amended hereby, the Lease shall 
    remain in full force and effect.

                    7.4  Conflicts.  In case of any conflict between any term 
    or provision of this Amendment and the Lease, the term or provision of this
    Amendment shall govern.

                    7.5  Counterparts.  This Amendment may be executed in one 
    or more counterparts, each of which shall be deemed an original, but all of
    which when taken together shall constitute one agreement.
