     Re: Carr Holdings/Sheridan Option

Dear Tom:

     Reference in this letter is made to the Sale and Purchase Agreement dated
as of March 28, 2005 (the "Sale and Purchase Agreement") between you, Thomas
Sheridan, an individual resident of the State of New Jersey ("Buyer"), and Carr
Holdings, L.L.C., a New Jersey limited liability company ("Seller"), which is
attached hereto as Exhibit A. All capitalized terms used herein and not defined
herein shall have the meaning assigned to such terms in the Sale and Purchase
Agreement.

     Pursuant to the Sale and Purchase Agreement, Seller granted Buyer an Option
to purchase up to 20,000 Common Shares of Heartland at an aggregate purchase
price of $18.55 per share (or an Option to purchase an aggregate of 40,000
Common Shares at a purchase price of $9.275 after giving effect to the
two-for-one split of Heartland's Common Shares that occurred on July 26, 2005
(the "Stock Split").

     On August 8, 2005, Buyer exercised part of the Option and purchased 12,000
Common Shares (post Stock Split) from Seller at $9.275 per Common Share. The
balance of the Option remaining after such exercise is 28,000 Common Shares
(post Stock Split).

     We ask you to confirm our agreement, by your signature below, that:

     1. Seller agrees to pay, and Buyer agrees to accept, an amount equal to the
sum derived as follows: the closing price per Common Share of Heartland,
excluding any trades which are not bona fide, arm's length transactions (and the
closing price for such day shall be the last sale price on such date) as
officially reported on the New York Stock Exchange the last business day before
the date of this letter less $9.275 per Common Share multiplied by 28,000, by
wire transfer of immediately available funds to an account designated by Seller,
against delivery of a countersigned copy of this letter.

     2. The Sale and Purchase Agreement shall hereby terminate and all
outstanding obligations and liabilities between the parties arising from the
Sale and Purchase Agreement except those described in Section 6 thereof,
relating to taxes, and any other provisions of the Sale and Purchase Agreement
which by their nature are intended to survive any such termination.

     3. This letter agreement contains the entire understanding between the
parties hereto with respect to the subject matter hereof and supersedes any and
all prior understanding, agreements or representations, written or oral,
relating to the subject matter hereof.

     4. Buyer and Seller will each execute and deliver or cause to be executed
and delivered all further documents and instruments and take all such further
action as may be reasonably necessary in order to consummate the transactions
contemplated hereby.

<PAGE>

     5. All matters relating to the interpretation, construction, validity and
enforcement of this letter agreement shall be governed by the internal laws of
the State of New York, without giving effect to any choice of law provisions
thereof to the extent such principles would lead to the application of a
substantive law other than the law of the State of New York.

     6. Each party hereto agrees that any suit, action or proceeding based on
any matter arising out of or in connection with this letter agreement or the
transactions contemplated hereby shall be brought in the United States District
Court for the Southern District of New York or any New York State court sitting
in New York City, and each party hereby irrevocably consents to the jurisdiction
of such courts (and of the appropriate appellate courts therefrom) in any such
suit, action or proceeding and irrevocably waives, to the fullest extent
permitted by law, any objection that it may now or hereafter have to the laying
of the venue of any such suit, action or proceeding in any such court or that
any such suit, action or proceeding which is brought in any such court has been
brought in an inconvenient forum.

     7. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL
BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS LETTER
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

     8. This letter agreement may be executed in any number of counterparts,
each of which shall be deemed to be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

Mr. Thomas Sheridan

     Re: Sale of Shares of Common Stock of Heartland Payment Systems, Inc.

Dear Thomas:

     The following letter agreement is intended to memorialize and effectuate
the transfer we agreed upon orally in October 2004 and, therefore, sets forth
the terms and conditions pursuant to which you, Thomas Sheridan, an individual
resident of California ("BUYER"), has agreed to purchase 20,000 shares of common
stock, par value $0.001 per share ("COMMON SHARES"), of Heartland Payment
Systems, Inc., a Delaware corporation ("HEARTLAND"), from Carr Holdings LLC, a
New Jersey limited liability company ("SELLER"). The Common Shares being
purchased by the Buyer hereunder are hereinafter referred to as the "CARR

     1. Sale of the Carr Shares. (a) Subject to the terms and conditions of this
letter agreement, on a mutually agreed date to be not later than March 31, 2005
(the "CLOSING DATE"), Seller agrees to sell, and Buyer agrees to purchase the
Carr Shares at a price of $18.55 per share, for an aggregate purchase price of
$371,000.00 (the "PURCHASE PRICE").

          (b) The Purchase Price shall be payable on the Closing Date to Seller
by Buyer by wire transfer of immediately available funds to an account
designated by Seller, against delivery of the stock certificate(s) representing
the Carr Shares properly endorsed or accompanied by a stock power.

     2. Option.

          (a) Seller hereby grants Buyer an irrevocable option (the "OPTION") to
purchase an additional 20,000 Common Shares of Heartland (the "OPTIONED SHARES")
at an aggregate purchase price of $371,000.00 (the "OPTION PURCHASE PRICE"),
subject to the terms and conditions provided herein.

          (b) Subject to the conditions below and as set forth in Section 2(e)
hereof, Buyer may exercise the Option at any time on any business day after the
Closing Date and prior to the earlier of (i) 5:00 p.m., New York City time, on
March 31, 2006, if Heartland shall not have consummated an underwritten initial
public offering ("IPO"), or (ii) 5:00 p.m., New York City time, nine months and
15 days after consummation of the IPO if the IPO occurs before March 31, 2006

          (c) If Buyer wishes to exercise the Option for all of the Optioned
Shares, Buyer shall send a written notice (the "EXERCISE NOTICE") to Seller
specifying the place and date of purchase (which shall not be more than 30 days
after the Exercise Notice, and no later than the Expiration Date), and the time
of the closing of such purchase. The closing of the purchase of Optioned Shares
(the "OPTION CLOSING") shall take place at the place, on the date (the "OPTION

Notice; provided that if, at the Option Closing Date, the conditions set forth
in Section 2(e) shall not have been satisfied (or waived by Seller), Buyer may
postpone the Option Closing until a date within five business days after such
conditions are satisfied (but no later than the Expiration Date).

          (d) The Option Purchase Price for the Optioned Shares purchased upon
exercise of the Option shall be payable to Seller by Buyer by wire transfer of
immediately available funds to an account designated by Seller, against delivery
of the stock certificate(s) representing the Optioned Shares properly endorsed

shall have received a signed certificate by Buyer to the foregoing effect, and
(ii) there shall be no preliminary or permanent injunction or other order,
decree or ruling issued by a court of competent jurisdiction or by a
