     6.   Termination
          -----------

          (a) The Company may terminate the Executive's employment for "Cause."
For purposes of this Agreement, "Cause" shall mean and be limited to (i) the
demonstrated continued failure by the Executive materially to perform his duties
under this Agreement (other than by reason of his Disability, as defined in
Paragraph 6(d) below) or the commission in bad faith by the Executive of any act
which materially injures the Company, and which in either case is not remedied
within thirty (30) days after receipt of written notice from the Company stating
in detail the particular act or failures that constitute the grounds on which
the termination for cause is based; (ii) the commission by the Executive in the
course of his employment of an act which constitutes fraud, embezzlement or
theft against the Company; or (iii) the conviction of the Executive of a felony
or other crime involving a breach of trust or fiduciary duty owed to the
Company.

          (b) The Executive shall be entitled to terminate his employment for
"Good Reason" at any time during the Term by written notice to the Company.  For
purposes of this Agreement, "Good Reason" shall mean: (i) the assignment to the
Executive of any duties materially inconsistent in any respect with the
Executive's position (including status, offices, titles and reporting
requirements), authority, duties or responsibilities as contemplated by
Paragraph 3 above; (ii) the Company's requiring the Executive to be based at any
office or location other than an office located in San Diego, California at any
time after ninety (90) days from the date of this Agreement; or (iii) the

                                      -3-
<PAGE>

and/or capital for internal growth and cash flow needs of the Company and the
capital required to complete the acquisitions sought by the Executive and
approved by the Board.

          (c) In the event the Executive shall be unable to perform his duties

causes being herein referred to as "Disability") and the Executive shall fail to
perform such duties for periods aggregating sixty (60) days, whether or not
continuous, in any continuous period of one hundred eighty (180) days, the
Company shall have the right to terminate the Executive's employment hereunder
as of the end of any calendar month during the continuance of such Disability
upon not less than thirty (30) days' prior written notice to him.  In addition,
if at any time a Board certified licensed physician in the State of California
selected by the Board and reasonably satisfactory to the Executive or his
personal representative determines that the Executive has incurred a Disability
that in all likelihood would continue for the period that would permit the
Company to terminate the Executive's employment under this Subparagraph 6(d),
the Company may terminate the Executive's employment hereunder upon written
notice to him.  Such notice shall be accompanied by the written determination of
such physician indicating the basis for his or her determination.

              (ii)  the balance of any unpaid amounts due under Paragraph 4

relationship of confidence and trust with the Company and will come into
possession of "Confidential Information" (1) owned

                                      -4-
<PAGE>

or controlled by the Company, (2) in the possession of the Company and belonging
to third parties or (3) conceived, originated, discovered or developed, in whole
or in part, by the Executive. As used herein "Confidential Information" includes

or marketing plans, studies, analyses, projections and reports, communications
by or to attorneys (including attorney-client privileged communications), memos
and other materials prepared by attorneys or under their direction (including

is not readily available to the public shall be considered to be a trade secret
and confidential and proprietary, even if it is not specifically marked as such,
unless the Company advises the Executive otherwise in writing or unless the
information has been shared by the Company or its staff with entities not bound
by non-disclosure agreements.

          (b) The Executive agrees that he will not, without the prior written
consent of the Company, directly or indirectly, use or disclose Confidential
Information to any person, during or after the Executive's employment, except as
may be necessary in the ordinary course of performing the Executive's duties
under this Agreement, or as required by law or the courts.  The Executive will

description, or any reproduction thereof of any description, containing or

is free to use information that is in the public domain (not as a result of a
breach of this Agreement).

          (d) During the term of this Agreement and for a twelve (12) month
period thereafter, the Executive agrees that he shall not (a) engage or be
interested in or receive any compensation from any business in which the
services to be rendered by the Executive to such business directly relates to
services or products that are directly competitive with "Significant" services
or products offered by the Company or a Controlled Affiliate (as hereinafter
defined) at the Executive's Date of Termination, or (b) induce or attempt to
induce any employee, agent or customer of the Company to terminate or reduce the
scope of his, her or its relationship with the Company.  A product or service
shall be deemed "Significant" only if such service or product on the Date of
Termination constitutes or is reasonably expected to constitute a material
component of the core business of the Company and its controlled affiliates
taken as a whole.  As used herein, the term "Controlled Affiliate" shall mean
any entity which by ownership of voting securities or agreement is, directly or
indirectly through one or more intermediaries, controlled by the Company.

          (e) The Executive acknowledges and agrees that the Company may seek to
enforce the covenants and restrictions pertaining to his obligations in this
Paragraph 8 hereof at law or in equity.  If a court determines that the
restrictions in this Paragraph 8 are too broad or

                                      -5-

otherwise unreasonable under applicable law, including with respect to time or
geographical scope, the court is hereby requested and authorized by the parties

empowered to do so under the deceased Employee's will or under the then
applicable laws of descent and distribution.

Section 4.2. - Partial Exercise
------------   ----------------

          Any exercisable portion of the Option or the entire Option, if then

the time when the Option or portion thereof becomes unexercisable under Section
3.3; provided, however, that each partial exercise shall be for not less than

by the Committee stating that the Option, or a portion thereof, is exercised.
The notice shall be signed by the Employee or other person then entitled to
exercise the Option or such portion; and

          (b) (i) Full cash payment to the Secretary of the Company for the
shares with respect to which such Option or portion is exercised; or

                                       6
<PAGE>

               (ii)  (A) shares of the Company's Class A Common Stock owned by
          the Employee, duly endorsed for transfer to the Company, with a Fair
          Market Value on the date of delivery equal to the aggregate exercise
          price of the Option or exercised portion thereof, or (B) shares of the
          Company's Class A Common Stock issuable to the Employee upon exercise
          of the Option, with a Fair Market Value on the date of exercise of the
          Option or any portion thereof equal to the aggregate exercise price of
          the Option or exercised portion thereof; or

               (iii) With the consent of the Committee, a full recourse
          promissory note bearing interest (at no less than such rate as shall
          then preclude the imputation of interest under the Code or successor
          provision) and payable upon such terms as may be prescribed by the
          Committee. The Committee may also prescribe the form of such note and
          the security to be given for such note. The Option may not be
          exercised, however, by delivery of a promissory note or by a loan from
          the Company when or where such loan or other extension of credit is
          prohibited by law; or

               (iv)  With the consent of the Committee, property of any kind
          which constitutes good and valuable consideration; or

               (v)   A notice that the Employee has placed a market sell order
          with a broker with respect to shares of the Company's Class A Common
          Stock then issuable upon exercise of the Option, and that the broker
          has been directed to pay a sufficient portion of the net proceeds of
          the sale to the Company in satisfaction of the Option exercise price;
          or

               (vi)  With the consent of the Committee, any combination of the
          consideration provided in the foregoing subparagraphs (i), (ii),
          (iii), (iv) and (v); and

          (c) A bona fide written representation and agreement, in a form
reasonably satisfactory to the Committee, signed by the Employee or other person
then entitled to exercise such Option or portion, stating that the shares of
stock are being acquired for his own account, for investment and without any
present intention of distributing or reselling said shares or any of them except
as may be permitted under the Securities Act and then applicable rules and
regulations thereunder, and that the Employee or other person then entitled to
exercise such Option or portion will indemnify the Company against and hold it
free and harmless from any loss, damage, expense or liability resulting to the
Company if any sale or distribution of the shares by such person is contrary to
the representation and agreement referred to above. The Committee may, in its
reasonable discretion, take whatever additional actions it deems appropriate to
insure the observance and performance of such representation and agreement and
to effect compliance with the Securities Act and any other federal or state
securities laws or regulations. Without limiting the generality of the
foregoing, the Committee may require an opinion of counsel reasonably acceptable
to it to the effect that any subsequent transfer of shares acquired on an Option
exercise does not violate the Securities Act, and may issue stop-transfer orders
covering such shares. Share certificates evidencing stock issued on exercise of
this Option shall bear an appropriate legend referring to the provisions of this
subsection (c) and the agreements herein. The written representation and
agreement referred to in the first sentence of this subsection (c) shall,
however, not be required if the shares to be issued pursuant to such

                                       7
<PAGE>

exercise have been registered under the Securities Act, and such registration is
then effective in respect of such shares;

          (d) Full payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; (i) shares of the Company's Class A Common Stock
owned by the Employee, duly endorsed for transfer, with a Fair Market Value on
the date of delivery equal to the sums required to be withheld, or (ii) shares
of the Company's Class A Common Stock issuable to the Employee upon exercise of
the Option with a Fair Market Value on the date of exercise of the Option or any
portion thereof equal to the sums required to be withheld, may be used to make
all or part of such payment; and

          (e) In the event the Option or portion shall be exercised pursuant to
Section 4.1 by any person or persons other than the Employee, appropriate proof
of the right of such person or persons to exercise the Option.

Section 4.4. - Conditions to Issuance of Stock Certificates
------------   --------------------------------------------

     The shares of stock deliverable upon the exercise of the Option, or any
portion thereof, may be either previously authorized but unissued shares or
issued shares which have then been reacquired by the Company. Such shares shall
be fully paid and nonassessable. The Company shall not be required to issue or
deliver any certificate or certificates for shares of stock purchased upon the
exercise of the Option or portion thereof prior to fulfillment of all of the
following conditions:

          (a) The admission of such shares to listing on all stock exchanges on
which such class of stock is then listed; and

          (b) The completion of any registration or other qualification of such
shares under any state or federal law or under rulings or regulations of the
Securities and Exchange Commission or of any other governmental regulatory body,
which the Committee shall, in its absolute discretion, deem necessary or
advisable; and

          (c) The obtaining of any approval or other clearance from any state or
federal governmental agency which the Committee shall, in its absolute

the Company (or other employer corporation) is required to withhold upon
exercise of the Option; and

of the Option as the Committee may from time to time establish for reasons of
administrative convenience.
