SCHEDULE A-2


GRANT OF OPTIONS TO NATIONAL FINANCIAL COMMUNICATIONS CORP. IN ADVANCE OF
SERVICES RENDERED

         A.       Grant of Options and Option Exercise Price. As compensation
for the services to be rendered by Company hereunder, Client herewith issues and
grants to Company stock options (the "Options") to purchase an aggregate of
100,000 shares of Client's Common Stock as follows:

(i) 25,000 options at a strike price of $3.00 per share vesting immediately upon
signing of this agreement
(ii) 25,000 options at a strike price of $3.50 per share vesting 60 days after
the signing of this agreement
(iii) 25,000 options at a strike price of $4.00 per share vesting 90 days after
the signing of this agreement
(iv) 25,000 options at a strike price of $4.50 per share vesting 120 days after
the signing of this agreement

The Options are exercisable upon and subject to the terms and conditions
contained herein. The Options are exercisable during the period commencing on
the date hereof and ending three years subsequent to the termination date of
this Agreement. These restricted shares will be issued to the Company upon the
signing of this Agreement and held by the Client until payment is made.

         B.       Manner of Exercise. Exercise of any of the Options by Company
shall be by written notice to Client accompanied by Company's certified or bank
check for the purchase price of the shares being purchased. Upon receipt of such
notice and payment, Client shall promptly cause to be issued, without transfer
or issue tax to the option holder or other person entitled to exercise the
option, the number of shares for which the Option has been exercised, registered
in the name of Company. Such shares, when issued, shall be fully paid and
non-assessable.

         C.       Option Shares. Company acknowledges that any shares which it
may acquire from Client pursuant to the exercise of the Options provided for
herein will not have been registered pursuant to the Securities Act of 1933, as
amended (the "Securities Act"), and therefore may not be sold or transferred by
Company except in the event that such shares are the subject of a registration
statement or any future sale or transfer is, in the opinion of counsel for
Client, exempt from such registration provisions. Company acknowledges that any
shares which it may acquire pursuant to the exercise of the Options will be for
its own account and for investment purposes only and not with a view to the
resale or redistribution of same. Company further consents that the following
legend be placed upon all certificates for shares of Common Stock which may be
issued to Company upon the exercise of the Options:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") AND MAY NOT BE SOLD OR OTHERWISE
TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT
OR AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION
IS NOT REQUIRED."

Company further consents that no stop transfer instructions being placed against
all certificates may not be issued to it upon the exercise of the Options.

         (i)      If the Client executes a Registration during the term of the
contract, then the Company's shares will be added to this Registration at no
cost to the Company. The Client shall bear all costs and expenses attributable
to such registration, excluding fees and expenses of Company's counsel

<PAGE>

and any underwriting or selling commission. Client shall maintain the
effectiveness of such registration throughout the term of this Agreement and for
a 120 day period thereafter.

         (ii)     Notwithstanding the foregoing, if the Shares issuable upon
exercise of the Options are not otherwise registered under the Securities Act
and the Client shall at any time after the date hereof propose to file a
registration statement under the Securities Act, which registration statement
shall include shares of Common Stock of Client or any selling shareholder,
Client shall give written notice to Company of such proposed registration and
will permit Company to include in such registration all Shares which it has
acquired as of the date of such notice. The Client shall bear all costs and
expenses attributable to such registration, excluding fees and expenses of
Company's counsel and any underwriting or selling commission.

D.       Adjustments in Option Shares.

         (i)      In the event that Client shall at any time sub-divide its
outstanding shares of Common Stock into a greater number of shares, the Option
purchase price in effect prior to such sub-division shall be proportionately
reduced and the number of shares of Common Stock purchasable shall be
proportionately increased. In case the outstanding shares of Common Stock of
Client shall be combined into a smaller number of shares, the Option purchase
price in effect immediately prior to such combination shall be proportionately
increased and the number of shares of Common Stock purchasable shall be
proportionately reduced.

         (ii)     In case of any reclassification or change of outstanding
shares of Common Stock issuable upon exercise of this Option (other than change
in par value, or from par value to no par value, or from no par value to par
value, or as a result or a subdivision or combination), or in case of any
consolidation or merger of the Client with or into another corporation (other
than a merger in which the Client is the continuing corporation and which does
not result in any reclassification or change of outstanding shares of Common
Stock, other than a change in number of the shares issuable upon exercise of the
Option) or in case of any sale or conveyance to another corporation of the
property of the Client as an entirety or substantially as an entirety, the
Holder of this Option shall have the right thereafter to exercise this Option
into the kind and amount of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance by a holder of the number of shares of Common Stock of the Client for
which the Option might have been exercised immediately prior to such
reclassification, change, consolidation, merger, sale or conveyance. The above
provisions shall similarly apply to successive reclassifications and changes of
shares of Common Stock and to successive consolidations, mergers, sales or
conveyances.

         (iii)    The Company reserves the right to assign these options to a
third party at its own discretion.
