      GUARANTY made as of the 10th day of April, 2006, by SALES LEAD MANAGEMENT
INC., a Delaware corporation (the "Guarantor"), in favor of AEGIS NY VENTURE
FUND, LP, a New York limited partnership having an office at 787 Seventh Avenue
- 9th Floor, New York, NY 10019 (the "Lender").

                                   WITNESSETH:

      WHEREAS, Lender has agreed to make a loan in the principal amount of FIVE
HUNDRED THOUSAND and 00/100 ($500,000.00) (the "Loan") to SLM Holdings, INC. a
Delaware corporation (the "Borrower"), which is evidenced by Borrower's
promissory note, of like principal amount (the "Note"), dated the date hereof,
and secured by and/or entitled to the benefits of, among other things, (i) the
Loan and Security Agreement, dated as of the date hereof, by and among Borrower,
Guarantor and Lender (the "Loan Agreement") and (ii) any other document
evidencing, securing or otherwise relating to the Loan now or hereafter executed
and delivered by any of Borrower or any guarantor, as the case may be, to Lender
and any amendments, modifications, renewals, extensions and replacements thereof
and substitutions therefor (collectively, the "Loan Documents");

      WHEREAS, Guarantor will receive substantial direct and indirect benefit by
reason of Lender making the Loan to Borrower;

      WHEREAS, Guarantor granted a security interest to Lender pursuant to the
Loan Agreement, to secure, among other matters, its obligations to Lender
pursuant to this Guaranty;

      WHEREAS, Guarantor has determined that his execution, delivery and
performance of this Guaranty directly benefit, and are in the best interests of,
Guarantor; and

      WHEREAS, it is a condition precedent to the making of Loan by Lender that
Guarantor shall have executed and delivered to Lender a guaranty guaranteeing
the obligations of Borrower under the Loan Documents.

      NOW, THEREFORE, in consideration of the premises and the agreements
herein, and in order to induce Lender to make and maintain the Loan, Guarantor,
intending to be legally bound, hereby agrees with Lender as follows:

      1. DEFINITIONS. Reference is hereby made to the Loan Agreement and the
other Loan Documents for a statement of the terms thereof, and Guarantor
represents and warrants that he has read and reviewed each of the Loan
Documents. Unless otherwise defined herein, all terms used in this Guaranty and
not otherwise defined herein shall have the meanings ascribed thereto in the
Loan Agreement.



      2. GUARANTY.

      a. Guarantor hereby (i) irrevocably, absolutely and unconditionally
guarantees, as guarantor of payment and performance and not merely as a
guarantor of collection, to Lender and its successors, endorsees, transferees
and assigns, (A) the prompt payment by Borrower, as and when due and payable
(whether by scheduled maturity, required prepayment, acceleration, demand or
otherwise), of all amounts now or hereafter owing in respect of the Note, the
Loan Agreement and the other Loan Documents, whether for principal, interest,
fees, expenses or otherwise and (B) the due performance and observance by
Borrower of its other obligations now or hereafter existing in respect of the
Loan Documents (collectively, the "Obligations"); and (ii) agrees to pay any and
all expenses (including reasonable counsel fees and expenses) incurred by Lender
in enforcing its rights under this Guaranty.

      b. This Guaranty (i) is a continuing guaranty and shall remain in full
force and effect until satisfaction in full of the Obligations and the payment
of the other expenses to be paid by Guarantor pursuant hereto, and (ii) shall
continue to be effective or shall be reinstated, as the case may be, if at any
time any payment of any of the Obligations is rescinded or must otherwise be
returned by Lender upon the insolvency, bankruptcy or reorganization of Borrower
or otherwise, all as though such payment had not been made.

      3. GUARANTOR'S OBLIGATIONS UNCONDITIONAL. Guarantor hereby guarantees that
the Obligations will be paid and performed strictly in accordance with the terms
of the Loan Documents, regardless of any law, regulation or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of Lender with respect thereto. The liability of Guarantor under this
Guaranty shall be absolute and unconditional irrespective of: (i) any lack of
validity or enforceability of any Loan Document or any agreement or instrument
relating thereto; (ii) any change in the time, manner or place of payment of, or
in any other term in respect of, all or any of the Obligations, or any other
amendment or waiver of or consent to any departure from any Loan Document; (iii)
any change, amendment or modification of any Loan Document; (iv) any exchange or
release of, or non-perfection of any lien on or security interest in, any
collateral, or any release or amendment or waiver of or consent to any departure
from any other guaranty, for all or any of the Obligations or obligations of
Borrower under any Loan Document; or (v) any other circumstance which might
otherwise constitute a defense available to, or a discharge of, Borrower or any
Guarantor or any other guarantor in respect of the Obligations or the
obligations of Borrower under the Loan Documents.

      4. WAIVERS. Guarantor hereby waives (i) promptness and diligence; (ii)
notice of acceptance and notice of the incurrence of any Obligation by Borrower
or any obligations of Borrower under the Loan Documents; (iii) notice of any
actions taken by Lender or Borrower or any other party under any Loan Document
or any other agreement or instrument relating thereto; (iv) all other notices,
demands and protests, and all other formalities of every kind in connection with
the enforcement of the Obligations or of the obligations of Borrower or any
other party under any Loan Document or of the obligations of Guarantor
hereunder, the omission of or delay in which, but for the

                                        2



provisions of this Section 4, might constitute grounds for relieving Guarantor
of his obligations hereunder; and (v) any requirement that Lender protect,
secure, perfect or insure any security interest or lien or any property subject
thereto or exhaust any right or take any action against Borrower or any other
person or any collateral.

      5. SUBROGATION. In consideration of the benefits accruing to Guarantor
from Borrower and Lender, Guarantor hereby expressly waives all rights of
subrogation, contribution, indemnification or other similar legal or equitable
rights which Guarantor may now or hereafter otherwise be entitled to assert
against Borrower, whether arising by contract, by operation of law (including,
without limitation, any such right arising under any bankruptcy, insolvency or
similar law) or otherwise with respect to or by reason of any payment by
Guarantor under this Guaranty or on account of the Loan in connection herewith.
If any amount shall be paid to Guarantor on account of such subrogation rights
at any time when all of the Obligations and all other obligations and other
expenses to be paid by Guarantor pursuant hereto shall not have been paid in
full, such amount shall be held in trust for the benefit of Lender, shall be
segregated from the other funds of Guarantor and shall forthwith be paid over to
Lender to be applied in whole or in part by Lender against the Obligations.
Guarantor hereby agrees that this Guaranty shall continue to be effective or be
reinstated, as the case may be, if at any time payment of any amount due under
this Agreement or otherwise with respect to the Loan is rescinded or must
otherwise be restored or returned by Lender upon the insolvency, bankruptcy,
receivership, dissolution, liquidation, or reorganization of Borrower, or upon
or as a result of the appointment of a receiver or conservator of, a trustee or
similar officer for the Borrower, or otherwise, all as though such payment had
not been made and irrespective of whether such payment is returned to the party
who originally made it or some other party.

follows:

rights under any other Loan Document, to any other person, and such other person
shall thereupon become vested with all of the benefits in respect thereof
granted to Lender herein or otherwise. None of the rights or obligations of
Guarantor hereunder may be assigned or otherwise transferred without the prior
written consent of Lender.
