                             -------

          4.  Register of Securities; Restrictions on Transfer of Securities.
              --------------------------------------------------------------

              4.1 Register of Securities. The Company or its duly appointed
                  ----------------------
agent shall maintain, or cause its agent to maintain, a separate register for
the shares of Common Stock and Warrants, in which it shall register the issue
and sale of all such Securities. All transfers of Common Stock or Warrants shall
be recorded on the register maintained by the Company or its agent, and the
Company shall be entitled to regard the registered holder of such Securities as
the actual holder of the Securities so registered until the Company or its agent
is required to record a transfer of such Securities on its register. Subject to
Section 4.2(c) hereof, the Company or its agent shall be required to record any
--------------
such transfer when it receives the Security to be transferred,
<PAGE>

duly and properly endorsed by the registered holder thereof or by its attorney-
in-fact duly authorized in writing.

          4.2  Securities Act Restrictions on Transfer.
               ---------------------------------------

               (a) Purchaser understands and agrees that the Securities it will
be acquiring have not been registered under the Securities Act of 1933, as
amended (the "Securities Act"), and that accordingly such Securities will not be
      --------------
transferable except as permitted under various exemptions contained in the
Securities Act and any applicable state securities laws, or upon satisfaction of
the registration and prospectus delivery requirements of the Securities Act and
applicable state securities laws.  Purchaser acknowledges that it must bear the
economic risk of its investment in the Common Stock, the Warrants and the Common
Stock issuable upon exercise of the Warrants for an indefinite period of time
(subject, however, to the Company's obligation to effect the registration under
the Securities Act of the Common Stock purchased pursuant hereto and issuable
upon exercise of the Warrants in accordance with the Registration Agreement)
because such stock has not been registered under the Securities Act and
therefore cannot be sold, unless such stock is subsequently registered or an
exemption from registration is available.

               (b) Purchaser hereby represents and warrants to the Company that
(i) it is acquiring the Common Stock and Warrants it has agreed to acquire
hereunder for investment purposes, for its own account, and not with the view
to, or for resale in connection with, any distribution thereof within the
meaning of the Securities Act, (ii) it is an "accredited investor" as that term
is defined in Rule 501 under the Securities Act, (iii) it has the power and
authority under Applicable Law and its organizational documents, and has taken
all necessary corporate or similar action to authorize it, to enter into this
Agreement and to acquire the Securities, (iv) its execution and performance of
this Agreement will not conflict with, result in a breach of or a violation
under any material agreement to which it is a party, and (v) it has reviewed the
Company's reports, statements and other filings filed with the Securities and
Exchange Commission (the "Commission"), including without limitation, the
                          ----------
Company's Annual Report on Form 10-KSB for the fiscal year ended January 27,
2001 as filed with the Commission on April 30, 2001, the Company's Registration
Statement on Form SB-2 as filed with the Commission on January 25, 2001 (as
supplemented from time to time), the Company's Consent Solicitation Statement as
filed with the Commission on May 17, 2001, and the Company's Quarterly Report on
Form 10-QSB for the quarter ended April 28, 2001, and has had the opportunity to
ask questions and receive answers from representatives of the Company concerning
the business and financial condition of the Company and all of such questions
have been answered to the satisfaction of Purchaser.

               (c) Purchaser hereby agrees with the Company as follows:

                   (i) The certificates evidencing the Common Stock it has
agreed to purchase and each certificate issued in transfer thereof, and each
certificate evidencing the Common Stock issued upon exercise of the Warrants,
will bear the following legend:

     "The securities evidenced by this certificate have been acquired for
     investment and have not been registered under the Securities Act of 1933,
     as

                                      -2-
<PAGE>

     amended, or under any applicable state securities laws. The securities may
     not be sold or transferred in the absence of such registration or unless
     the request for transfer is accompanied by an opinion of counsel,
     reasonably satisfactory to the Company, stating that such transfer is
     exempt therefrom under such Act and under any applicable state securities
     laws."

                   (ii)   The certificates representing such Common Stock and
each certificate issued in transfer thereof, and each certificate evidencing the
Common Stock issued upon exercise of the Warrants, will also bear any legend
required under any applicable state securities laws.

                   (iii)  Absent an effective registration statement under the
Securities Act covering the disposition of the Securities, Purchaser will not
sell, transfer, assign, pledge, hypothecate or otherwise dispose of any of such
securities except in compliance with the Securities Act and the registration or
qualification requirements of any applicable state Securities laws or any
exemption therefrom.

                   (iv)   The Company shall make a notation on its records and
may give instructions to any transfer agent of the Common Stock in order to
implement the restrictions on transfer set forth in this subsection (c).

     5.   Representations and Warranties by the Company.  In order to induce the
          ---------------------------------------------
Purchaser to enter into this Agreement and to purchase the Common Stock and
Warrants, the Company hereby covenants with, and represents and warrants to,

business in each jurisdiction in which the character of its properties or the
nature of its businesses requires such qualification or authorization, except
for such jurisdictions where the failure to so qualify or be authorized would
not be reasonably likely to have a Materially Adverse Effect. Annex 5.1
                                                              ---------

any stock or securities convertible into or exchangeable for any shares of its
Common Stock, nor are there any preemptive or similar rights to subscribe for or

for any Common Stock. Except as set forth on Annex 5.1, the Company is not
                                             ---------
subject to any obligation (contingent or otherwise) to repurchase or otherwise

outstanding.

               (b) The Common Stock to be issued pursuant hereto has been duly
authorized and, when issued and paid for pursuant to the terms of this

               -------------
all necessary corporate action to authorize it to issue the Common Stock and to
execute, deliver and perform this Agreement, the Registration Agreement, the
Stockholders' Agreement and the Warrants in accordance with their respective
terms, and to consummate the transactions contemplated hereby and thereby.  This
Agreement has been duly executed and delivered by the Company and is, along with
the Registration Agreement, the Stockholders' Agreement and the Warrants, a
legal, valid and binding obligation of the Company enforceable in accordance
with its terms, except as enforceability may be limited by bankruptcy,
insolvency, moratorium, or other laws affecting the enforcement of creditors'
rights generally or by general equitable principles (regardless of whether such
enforceability is considered in an action, suit or proceeding in equity or at
law).

          5.3  Subsidiaries. The Subsidiaries of the Company are listed on Annex
               ------------                                                -----
5.3. Each such Subsidiary is a corporation duly organized, validly existing and
---
in good standing under the laws of the jurisdiction of its incorporation. Each
such Subsidiary has the corporate power and authority to own or lease and
operate its properties and to carry on its business as it is now being and
hereafter proposed to be conducted. Each Subsidiary is duly qualified, in good
standing and authorized to do business in each jurisdiction in which the
character of its properties or the nature of its business requires such
qualification or authorization. The Company owns all of the outstanding capital
stock of each Subsidiary, except as set forth on Annex 5.3.

          5.4  Compliance with Other Documents and Contemplated Transactions.
               -------------------------------------------------------------
The execution, delivery and performance by the Company of this Agreement, the
Warrants, the Registration Agreement and the Stockholders' Agreement, each in
accordance with their respective terms, and the consummation of the transactions
contemplated hereby and thereby, do not and will not (i) require any consent,
approval, authorization, permit or license which has not already been obtained
from, or require the Company to effect any filing or registration which has not
already been effected with, any federal, state or local regulatory authority,
(ii) violate any Applicable Law with respect to the Company, except any such
violation which would not be reasonably likely to have a Materially Adverse
Effect, (iii) conflict with, result in a breach of, or constitute a default

any indenture, agreement, credit facility or other instrument to which the
Company or any Subsidiary of the Company is a party or by which any such company
or its properties may be

                                      -4-
<PAGE>

bound or (iv) result in or require the creation or imposition of any Lien upon
or with respect to any Property now owned or hereafter acquired by the Company

          5.5  Compliance with Law.  Except as set forth in Annex 5.5 hereto,
               -------------------                          ---------
the Company is in substantial compliance with all Applicable Laws, except any
non-compliance which would not be reasonably likely to have a Materially Adverse
Effect.

          5.6  Title to Properties. Except as set forth on Annex 5.6, the
               -------------------                         ---------
Company has good and marketable title to, or a valid leasehold interest in, all
of its assets. None of such assets is subject to any Liens, except for Permitted
Liens. Except for financing statements evidencing Permitted Liens, no financing
statement under the Uniform Commercial Code and no other filing which names the
Company as debtor or which covers or purports to cover any of the Company's
assets is on file in any state or other jurisdiction, and the Company has not
signed any such financing statement or filing (except as described above) or any
security agreement that has not been terminated, authorizing any secured party
thereunder to file any such financing statement or filing.

          5.7  Litigation.  Except as described on Annex 5.7 attached hereto,

there is no action, suit or proceeding pending or, to the best of the Company's
knowledge, threatened against or in any other manner relating directly and
adversely to the Company or any of its properties in any court or before any
arbitrator of any kind or before or by any governmental body and no such action,
suit, proceeding or investigation (i) calls into question the validity of this

(ii) for which adequate reserves have been provided on the books of the Company
and (iii) as to which no Lien other than a Permitted Lien has attached and no
foreclosure, distraint, sale or similar proceedings have been commenced.  The
charges, accruals and reserves on the books of the Company in respect of taxes
are, in the judgment of the Company, adequate.

          5.9  Financial Statements.  The Company has furnished or made
               --------------------

operations and cash flows for the fiscal year ended January 27, 2001 and its
unaudited consolidated balance sheet and statements of operations and cash flows

fairly in accordance with generally accepted accounting principles the Company's
financial position on and as at such dates and the results of operations for the
periods then ended, subject in the case of the unaudited financial statements to

<PAGE>

          5.10 No Adverse Change.  Since January 27, 2001, there has occurred no
               -----------------
event which is reasonably likely to have a Materially Adverse Effect.

          5.11 ERISA.  The Company and each ERISA Affiliate and each of their
               -----
respective Plans are in substantial compliance with ERISA and the Internal
Revenue Code, and neither the Company nor any of its ERISA Affiliates has
incurred any accumulated funding deficiency with respect to any such Plan within
the meaning of ERISA or the Internal Revenue Code.  The Company has not incurred
any material liability to the Pension Benefit Guaranty Corporation or any
successor thereto in connection with any such Plan.  The assets of each such
Plan which is subject to Title IV of ERISA are sufficient to provide the
benefits under such Plan for which the Pension Benefit Guaranty Corporation or
any successor thereto would guarantee payment if such Plan were terminated, and
such assets are also sufficient to provide all other benefits due under the Plan
prior to and upon termination.  No Reportable Event has occurred and is
continuing with respect to any such Plan.  No such Plan or trust created
thereunder, or any party in interest, fiduciary, trustee or administrator
thereof, has engaged in a "prohibited transaction" (as such term is defined in
Section 406 of ERISA or Section 4975 of the Internal Revenue Code) which would
subject such Plan or any other Plan of the Company, or any of its ERISA
Affiliates, any trust created thereunder, or any party in interest, fiduciary,
trustee or administrator thereof, or any party dealing with any such Plan or any
such trust to the tax or penalty on "prohibited transactions" imposed by Section
502 of ERISA or Section 4975 of the Internal Revenue Code.  Neither the Company
nor any of its ERISA Affiliates is a participant in or obliged to make any
payment to a Multiemployer Plan.

          5.12 Absence of Defaults, Etc. Except as set forth in Annex 5.12, the
               ------------------------                         ----------
Company is in compliance with all the provisions of its Certificate of
Incorporation and Bylaws, and no event has occurred or failed to occur, which
has not been remedied or waived, the occurrence or non-occurrence of which
constitutes, or which with the passage of time or giving of notice or both would
constitute a default or breach by the Company under any indenture, agreement,
credit facility or other instrument (collectively, the "Company Agreements") or
                                                        ------------------
under any judgment, decree or order to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries or
their properties may be bound or affected, except any such default or breach
which would not be reasonably likely to have a Materially Adverse Effect. All
Company Agreements are in full force and effect, and the Company has no
knowledge that any party to any Company Agreement is seeking or presently
intends to seek to (i) terminate, amend or modify such Company Agreement or (ii)
upon expiration of such Company Agreement, not renew such Company Agreement on
terms substantially similar to those currently contained in such Company
Agreement.

          5.13 Intellectual Property Rights, Etc.
               ---------------------------------

               (a) The Company owns or possesses sufficient legal rights to all
patents, patent applications, trademarks, service marks, trade names,
copyrights, trade secrets, licenses, know-how, concepts, computer programs and
software, technical data, proprietary rights, proprietary processes and other
information necessary for its business as previously conducted, as now conducted
and as currently proposed to be conducted by the Company (each such item, the
"Company Intellectual Property") without any conflict with or infringement of
 -----------------------------
the rights of others.  Annex 5.13 contains a complete list of all issued
                       ----------
patents, service marks,

                                      -6-
<PAGE>

trademarks and registered copyrights of the Company, any pending applications
therefor and registrations, renewals, extensions and the like thereof and all
other patentable Company Intellectual Property as to which the Company intends
to file applications describing where the Company is currently in the
application process. Except for proprietary information agreements with its
employees and consultants, and licenses or agreements entered into in the
ordinary course of the Company's business, consistent with past practices, there
are no outstanding options, licenses, or agreements of any kind relating to any
of the Company Intellectual Property, nor is the Company bound by or a party to
any options, licenses, or agreements of any kind with respect to the patents,
patent applications, trademarks, service marks, trade names, copyrights, trade
secrets, licenses, know-how, concepts, computer programs, technical data,
proprietary rights, proprietary processes and information of any other person or
entity. No person or entity has the right to purchase any of the Company
Intellectual Property owned by the Company. Each of the federal, state and other
governmental registrations with any country pertaining to the Company
Intellectual Property is valid and in full force and effect. No claims are
pending against the Company by any person with respect to the use of any Company
Intellectual Property or challenging or questioning the validity or
effectiveness of any license or agreement relating to the same. To the best of
the Company's knowledge, none of its employees, agents or contractors is
obligated under any contract (including licenses, covenants, or commitments of
any nature) or other agreement, or is subject to any judgment, decree, or order
of any court or administrative agency, that would interfere with the use of such
employee's best efforts to promote the interests of the Company, or that would
conflict with the Company's business as it is currently proposed to be
conducted. To the best of the Company's knowledge, neither the execution nor
delivery of this Agreement, nor the carrying on of the Company's business by the
employees of the Company, nor the conduct of the Company's business as currently
proposed will conflict with or result in a breach of the terms, conditions, or
provisions of, or constitute a default under, any contract, covenant, or
instrument under which any of such employees is now obligated. The Company has
no plan to, and does not believe it is or will be necessary to utilize, any
inventions of any of its employees (or individuals it currently intends to hire)
made prior to their employment by the Company that would infringe the rights of
others. Annex 5.13 sets forth a list of all jurisdictions in which the Company
        ----------
is operating under a trade name, and each jurisdiction in which any such trade
name is registered. No patent listed on Annex 5.13 has been or is now involved
                                        ----------
in any interference, reissue, reexamination or opposition proceeding, nor is the
Company aware of any potentially interfering patent or patent application of any
third party. No person or entity is presently selling or marketing a product
which is covered by such patents, and such patents have not been challenged or
threatened in any way. None of the current or former employees of the Company
are named as an inventor on any pending patent application. All patents listed
on Annex 5.13 are currently in compliance with formal legal requirements
   ----------
(including payment of filing, examination and maintenance fees and proofs of
working or use), and, there is nothing which would render such patents invalid
or unenforceable, and they are not subject to any maintenance fees or taxes or
actions falling due within ninety days after the date of Closing. To the best
knowledge of the Company, the Company Intellectual Property does not infringe
any rights of any third party, including without limitation, any rights under
the laws of patent, trademark, copyright, trade secret, or any personal, moral,
privacy, publicity, contract or other property rights. To the best knowledge of
the Company, the Company Intellectual Property has not been and is not currently
being infringed by any third party.

the Company, then separate counsel for the Indemnified Party shall be entitled
to participate in and conduct the defense, in the case of (i) and (ii)(x), or
such different defenses, in the case of (ii)(y), and the Company shall be liable
for any reasonable legal or other expenses incurred by the Indemnified Party in

                              WARRANT TO PURCHASE
                           SHARES OF COMMON STOCK OF
                            TELEHUBLINK CORPORATION



     This certifies that RNH Holding Ltd. and its registered successors and
assigns (the "Holder"), for value received, is entitled to purchase from
              ------
TeleHubLink Corporation, a Delaware corporation (the "Company"), having a place
                                                      -------
of business at One Technology Drive, Suite 135, Andover, MA  01810, a maximum of
three million eight hundred forty-six thousand one hundred fifty-four
(3,846,154) fully paid and nonassessable shares of the Company's Common Stock,
$0.01 par value ("Common Stock"), for a price of $1.30 per share (the "Stock
                  ------------                                         -----

(Eastern time) on July __, 2003 [24 months from Closing Date] (the "Expiration
                                                                    ----------
Date"), upon surrender to the Company at its principal office (or at such other
----
location as the Company may advise the Holder in writing) of this Warrant

                                                                ---------
filled in and signed and upon payment in cash or by check or pursuant to Section
1.2 hereof of the aggregate Stock Purchase Price for the number of shares for
which this Warrant is being exercised determined in accordance with the
provisions hereof.  The Stock Purchase
<PAGE>

Price and the number of shares purchasable hereunder are subject to adjustment
as provided in Section 3 of this Warrant.

     This Warrant is subject to the following terms and conditions.

     1.   Exercise; Issuance of Certificates; Payment for Shares.

          1.1  General.  This Warrant is exercisable at the option of the holder
of record hereof, at any time or from time to time, up to the Expiration Date
for all or any part of the shares of Common Stock (but not for a fraction of a
share) which may be purchased hereunder.  The Company agrees that the shares of
Common Stock purchased under this Warrant shall be and are deemed to be issued
to the Holder hereof as the record owner of such shares as of the close of
business on the date on which this Warrant shall have been surrendered, properly
endorsed, the completed, executed Subscription Form delivered and payment made
for such shares.  Certificates for the shares of Common Stock so purchased,
together with any other securities or property to which the Holder hereof is
entitled upon such exercise, shall be delivered to the Holder hereof by the
Company at the Company's expense within a reasonable time after the rights
represented by this Warrant have been so exercised.  In case of a purchase of
less than all the shares which may be purchased under this Warrant, the Company
shall cancel this Warrant and execute and deliver a new Warrant or Warrants of
like tenor for the balance of the shares purchasable under the Warrant
surrendered upon such purchase to the Holder hereof within a reasonable time.
Each stock certificate so delivered shall be in such denominations of Common
Stock as may be required by the Holder hereof and shall be registered in the
name of such Holder.


          1.2  Net Issue Exercise.  Notwithstanding any provisions herein to the
contrary, if the fair market value of one share of the Company's Common Stock is
greater than the Stock Purchase Price (at the date of calculation as set forth
below), in lieu of exercising this Warrant for cash, the Holder may elect to
receive shares equal to the value (as determined below) of this Warrant (or the
portion thereof being canceled) by surrender of this Warrant at the principal
office of the Company together with the properly endorsed Subscription Form and
notice of such election in which event the Company shall issue to the Holder a
number of shares of Common Stock computed using the following formula:


               X=Y (A-B)
                 -------
                    A

                                       2
<PAGE>

              Where X=   the number of Holder shares of Common Stock to be
                         issued to the Holder.

                    y=   number of shares of Common Stock purchasable under the
                         Warrant or, if only a portion of the Warrant is being
                         exercised, the portion of the Warrant being canceled
                         (at the date of such calculation)

                   A=    the fair market value of one share of the Company's
                         Common Stock (at the date of such calculation)

                   B=    Stock Purchase Price (as adjusted to the date of such
                         calculation)

For purposes of the above calculation, fair market value of one share of Common
Stock shall be determined as follows:

                   (i)   If the Common Stock is listed on a securities exchange
or quoted on the Nasdaq Stock Market or the over-the-counter market:


                         (a)  if traded on a securities exchange, the fair
market value shall be deemed to be the average of the closing prices over a ten
(10) trading day period ending three days before the day the current fair market
value of the securities is being determined; or


                         (b)  if actively traded over-the-counter, the fair
market value shall be deemed to be the average of the last reported sales prices
quoted on the Nasdaq Stock Market (or similar system, including the National
Quotation Bureau, Inc. system) over the ten (10) day period ending three days
before the day the current fair market value of the securities is being
determined; or


                   (ii)  If at any time the Common Stock is not listed on any
securities exchange or quoted on the Nasdaq Stock Market (or similar system) or
the over-the-counter market, the current fair market value of Common Stock shall
be determined in good faith by the Board of Directors not taking into account
any discount for illiquidity or lack of control.

                                       3
<PAGE>

     2.   Shares to the Fully Paid; Reservation of Shares.  The Company
covenants and agrees that all shares of Common Stock which may be issued upon
the exercise of the rights represented by this Warrant will, upon issuance, be
duly authorized, validly issued, fully paid and nonassessable and free from all
preemptive rights of any stockholder and free of all taxes, liens and charges
with respect to the issue thereof.  The Company further covenants and agrees
that during the period within which the rights represented by this Warrant  may
be exercised, the Company will at all times have authorized and reserved, for
the purpose of issue or transfer upon exercise of the subscription rights
evidenced by this Warrant, a sufficient number of shares of authorized but
unissued Common Stock, or other securities and property, when and as required to
provide for the exercise of the rights represented by this Warrant.  The Company
will take all such action as may be necessary to assure that such shares of
Common Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of any domestic securities
exchange upon which the Common Stock may be listed; provided, however, that the
                                                    --------  -------
Company shall not be required to effect a registration under Federal or State
securities laws with respect to such exercise.  The Company will not take any
action which would result in any adjustment of the Stock Purchase Price (as
adjusted under Section 3 hereof)  if the total number of shares of Common Stock
issuable after such action upon exercise of all outstanding warrants, together
with all shares of Common Stock then outstanding and all shares of Common Stock
then issuable upon exercise of all options and upon the conversion of all
convertible securities then outstanding, would exceed the total number of shares
of Common Stock then authorized by the Company's Certificate of Incorporation.


     3.   Adjustment of Stock Purchase Price and Number of Shares.  The Stock
Purchase Price and the number of shares purchasable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section 3.  Upon each adjustment of the Stock
Purchase Price, the Holder of this Warrant shall thereafter be entitled to
purchase, at the Stock Purchase Price resulting from such adjustment, the number
of shares obtained by multiplying the Stock Purchase Price in effect immediately
prior to such adjustment by the number of shares purchasable pursuant hereto
immediately prior to such adjustment, and dividing the product thereof by the
Stock Purchase Price resulting from such adjustment.


          3.1  Subdivision or Combination of Stock.  In case the Company shall
at any time subdivide its outstanding shares of Common Stock into a greater
number of shares, the Stock Purchase Price in effect immediately prior to such
subdivision shall

                                       4
<PAGE>

be proportionately reduced, and conversely, in case the outstanding shares of
Common Stock of the Company shall be combined into a smaller number of shares,
the Stock Purchase Price in effect immediately prior to such combination shall
be proportionately increased.

          3.2  Dividends in Common Stock, Other Stock, Property,
Reclassification.  If at any time or from time to time the holders of Common
Stock (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or become entitled to receive,
without payment therefor,

               (A)  Common Stock or any shares of stock or other securities
which are at any time directly or indirectly convertible into or exchangeable
for Common Stock, or any rights or options to subscribe for, purchase or
otherwise acquire any of the foregoing by way of dividend or other distribution,
or

               (B)  Common Stock or additional stock or other securities or
property (including cash) by way of spinoff, split-up, reclassification,
combination of shares or similar corporate rearrangement (other than (i) shares
of Common Stock issued as a stock split, adjustments in respect of which shall
be covered by the terms of Section 3.1 above or (ii) an event for which
adjustment is otherwise made pursuant to Section 3.3 below), then and in each
such case, the Holder hereof shall, upon the exercise of this Warrant, be
entitled to receive, in addition to the number of shares of Common Stock
receivable thereupon, and without payment of any additional consideration
therefor, the amount of stock and other securities and property (including cash)
which such Holder would hold on the date of such exercise had he been the holder
of record of such Common Stock as of the date on which holders of Common Stock
received or became entitled to receive such shares or other or additional stock
and other securities and property.

          3.3  Reorganization, Reclassification, Consolidation, Merger or Sale.
If any capital reorganization or reclassification of the capital stock of the
Company, or any consolidation or merger of the Company with another corporation,
or the sale of all or substantially all of its assets to another corporation
shall be effected in such a way that holders of Common Stock shall be entitled
to receive stock, securities, or other assets or property, then, as a condition
of such reorganization, reclassification, consolidation, merger or sale, lawful
and adequate provisions shall be made whereby the Holder hereof shall thereafter
have the right to purchase and receive (in lieu of the shares of the Common
Stock of the Company immediately theretofore purchasable and receivable

                                       5
<PAGE>

upon the exercise of the rights represented hereby) such shares of stock,
securities or other assets or property as may be issued or payable with respect
to or in exchange for a number of outstanding shares of such Common Stock equal
to the number of shares of such stock immediately theretofore purchasable and
receivable upon the exercise of the rights represented hereby. In any
reorganization or reclassification described above, appropriate provision shall
be made with respect to the rights and interests of the Holder of this Warrant
to the end that the provisions hereof (including, without limitation, provisions
for adjustments of the Stock Purchase Price and of the number of shares
purchasable and receivable upon the exercise of this Warrant) shall thereafter
be applicable, as nearly as may be, in relation to any shares of stock,
securities or assets thereafter deliverable upon the exercise hereof. The
Company will not effect any such consolidation, merger or sale unless, prior to
the consummation thereof, the successor corporation (if other than the Company)
resulting from such consolidation or the corporation purchasing such assets
shall assume by written instrument, executed and mailed or delivered to the
registered Holder hereof at the last address of such Holder appearing on the
books of the Company, the obligation to deliver to such Holder such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
such Holder may be entitled to purchase.

     3.4  Notice of Adjustment.  Upon any adjustment of the Stock Purchase Price
or any increase or decrease in the number of shares purchasable upon the
exercise of this Warrant, the Company shall give written notice thereof, by
first class mail, postage prepaid, addressed to the registered Holder of this
Warrant at the address of such Holder as shown on the books of the Company, and,
in case of a Holder with an address or record outside of the United States, by
facsimile, and confirmed in writing by first class air mail.  The notice shall
be signed by the Company's chief financial officer and shall state the Stock
Purchase Price resulting from such adjustment and the increase or decrease, if
any, in the number of shares purchasable at such price upon the exercise of this
Warrant, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based.

     3.5  Other Notices.  If at any time:

          (1) the Company shall declare any cash dividend upon its Common Stock;

          (2) the Company shall declare any dividend upon its Common Stock
payable in stock or make any special dividend or other distribution to the
holders of its

                                       6
<PAGE>

Common Stock;

          (3) the Company shall offer for subscription pro rata to the holders
of its Common Stock any additional shares of stock of any class or other rights;

          (4) there shall be any capital reorganization or reclassification of
the capital stock of the company; or consolidation or merger of the Company; or
consolidation or merger of the Company with, or sale of all or substantially all
of its assets to, another corporation; or

          (5) there shall be a voluntary or involuntary dissolution, liquidation
or winding-up of the Company;

then, in any one or more of said cases, the Company shall give, by first class
mail, postage prepaid, addressed to the Holder of this Warrant at the address of
such Holder as shown on the books of the Company, (a) at least ten (10) days'
prior written notice (by the method set forth in Section 3.4 above) of the date
on which the books of the Company shall close or a record shall be taken for
such dividend, distribution or subscription rights or for determining rights to
vote in respect of any such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation or winding-up, and (b) in the case of any
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding-up, at least ten (10) days' prior written notice of the
date when the same shall take place; provided, however, that failure to give
                                     --------  -------
such notice or any defects therein shall not affect the validity of the action
taken by the Company. Any notice given in accordance with the foregoing  clause
(a) shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Common Stock shall be
entitled thereto.  Any notice given in accordance with the foregoing clause (b)
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock for securities or the other property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation, winding-up or conversion, as the case may be.

     4.   Issue Tax.  The issuance of certificates for shares of Common Stock
upon the exercise of the Warrant shall be made without charge to the Holder of
the  Warrant for any issue tax (other than any applicable income taxes) in
respect thereof; provided, however, that the Company shall not be required to
                 --------  -------
pay any tax which may be payable in respect of any transfer involved in the
issuance and delivery of any certificate in a name other than that of the then
Holder of the Warrant being exercised.

                                       7
<PAGE>

     5.   Closing of Books. The Company will at no time close its transfer books
against the transfer of any warrant or of any shares of Common Stock issued or
issuable upon the exercise of any warrant in any manner which interferes with
the timely exercise of this Warrant.

     6.   No Voting or Dividend Rights; Limitations of Liability. Nothing
contained in this Warrant shall be construed as conferring upon the Holder
hereof the right to vote or to consent or to receive notice as a stockholder of
the Company or any other matters or any rights whatsoever as a stockholder of
the Company. No dividends or interest shall be payable or accrued in respect of
this Warrant or the interest represented hereby or the shares purchasable
hereunder until and only to the extent that this Warrant shall have been
exercised. No provisions hereof, in the absence of affirmative action by the
Holder to purchase shares of Common Stock, and no mere enumeration herein of the
rights or privileges of the Holder hereof, shall give rise to any liability of
such Holder for the Stock Purchase Price or as a stockholder of the Company,
whether such liability is asserted by the Company or by its creditors.

     7.   Transfer and Exchange. This Warrant and all rights hereunder are
transferable, in whole or in part, subject to compliance with applicable state
and federal securities laws. If such a proposed transfer is effected, this
Warrant is transferable on the books of the Company maintained for such purpose
at its principal office referred to above by the Holder hereof in person or by
duly authorized attorney, upon surrender of this Warrant properly endorsed and
upon payment of any necessary transfer tax or other governmental charge imposed
upon such transfer. Each taker and holder of this Warrant by taking or holding
the same, consents and agrees that this Warrant, when endorsed in blank, shall
be deemed negotiable and that when this Warrant shall have been so endorsed, the
Holder hereof may be treated by the Company and all other persons dealing with
this Warrant as the absolute owner hereof for any purpose and as the person
entitled to exercise the rights represented hereby, any notice to the contrary
notwithstanding; but until such transfer on such books, the Company may treat
the registered Holder hereof as the owner for all purposes.

     8.   Rights and Obligations Survive Exercise of Warrant.  The rights and
obligations of the Company, of the Holder of this Warrant and of the holder of
shares of Common Stock issued upon exercise of this Warrant referred to in
Section 7 shall survive the exercise of this Warrant.

                                       8
<PAGE>

     9.   Modification and Waiver.  This Warrant and any provision hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

     10.  Notices.  All notices, requests, consents and other communications
required or permitted hereunder shall be in writing and shall be delivered, or
mailed first class postage prepaid, registered or certified mail,

          (a) If to the Holder hereof at its address as shown on the books of
the Company

or

          (b) If to the Company at the address indicated therefor in the first
paragraph of this Warrant or such other address as the Company may specify by
written notice to the Holder hereof and each notice, request, consent and other
communication shall for all purposes of this Warrant be treated as being
effective or having been given when delivered, if delivered personally, by e-
mail with confirmation of receipt, by facsimile with confirmation of receipt or
by overnight courier or, if sent by mail, at the earlier of its actual receipt
or three (3) days after the same has been deposited in a regularly maintained
receptacle for the deposit of United States mail, addressed and postage prepaid
as aforesaid.

     11.  Binding Effect. This Warrant shall be binding upon any corporation
succeeding the Company by merger, consolidation or acquisition of all or
substantially all of the Company's assets.  All of the obligations of the
Company relating to the Common Stock issuable upon the exercise of this Warrant
shall survive the exercise and termination of this Warrant.  All of the
covenants and agreements of the Company shall inure to the benefit of the
successors and assigns of the Holder hereof.

     12.  Headings.  The headings of the Sections and paragraphs of this Warrant
are inserted for convenience and reference only and do not constitute a part of
this Warrant.

     13.  Lost Warrants. The Company represents and warrants to the Holder
hereof that upon receipt of evidence reasonably satisfactory to the Company of
the loss, theft, destruction, or mutilation of this Warrant and, in the case of
any such loss, theft or

                                       9
<PAGE>

destruction, upon receipt of an indemnity reasonably satisfactory to the
Company, or in the case of any such mutilation upon surrender and cancellation
of such Warrant, the Company, at its expense, will make and deliver a new
Warrant, of like tenor, in lieu of the lost, stolen, destroyed or mutilated
Warrant.

     14.  Fractional Shares.  No fractional shares shall be issued upon exercise
of this Warrant.  The Company shall, in lieu of issuing any fractional share,
pay the holder entitled to such fraction a sum in cash equal to such fraction
multiplied by the then effective Stock Purchase Price.

     15.  Choice of Law.  It is the intention of the Company and the Holder
hereof that the internal substantive laws, and not the laws of conflicts, of the
State of New York shall govern the enforceability and validity of this Warrant,
the construction of its terms and the interpretation of the rights and duties of
the Company and the Holder hereof.

     IN WITNESS WHEREOF, the Company has caused this Warrant to be duly executed
by its officers, thereunto duly authorized this ___ day of July 2001.

Attention: President

     The undersigned, RNH Holding Ltd. ("Purchaser"), intends to acquire up to
___________________________ shares of the Common Stock (the "Common Stock") of
TeleHubLink Corporation (the "Company") from the Company pursuant to the
exercise of a certain Warrant to purchase Common Stock held by Purchaser. The
Common Stock will be issued to Purchaser in a transaction not involving a public
offering and pursuant to an exemption from registration under the Securities Act
of 1933, as amended (the "1933 Act") and applicable state securities laws. In
connection with such purchase and in order to comply with the exemptions from
registration relied upon by the Company, Purchaser represents, warrants and
agrees as follows:

     Purchaser is acquiring the Common Stock for its own account, to hold for
investment, and Purchaser shall not make any sale, transfer or other disposition
of the Common Stock in violation of the 1933 Act or the General Rules and
Regulations promulgated thereunder by the Securities and Exchange Commission
(the "SEC") or in violation of any applicable state securities law.

     Purchaser has been advised that the Common Stock has not been registered
for initial issuance under the 1933 Act or state securities laws on the ground
that this transaction is exempt from registration, and that reliance by the
Company on such exemptions is predicated in part on Purchaser's representations
set forth in this letter.

     Purchaser has been informed that under the 1933 Act, the Common Stock must
be held indefinitely unless it is subsequently registered under the 1933 Act or
unless an exemption from such registration (such as Rule 144) is available with
respect to any proposed transfer or disposition by Purchaser of the Common
Stock.  Purchaser further agrees that the Company may refuse to permit Purchaser
to sell, transfer or dispose of the Common Stock (except as permitted under Rule
144) unless there is in effect a registration statement under the 1933 Act and
any applicable state securities laws covering such transfer, or unless Purchaser
furnishes an opinion

                                       2

of counsel reasonably satisfactory to counsel for the Company, to the effect
that such registration is not required.

     Purchaser also understands and agrees that there will be placed on the
certificate(s) for the Common Stock, or any substitutions therefor, a legend
stating in substance:

"These securities have not been registered under the Securities Act of 1933, as
amended, or under any applicable state securities laws. These securities may not
be sold or transferred in the absence of such registration or unless the request
for transfer is accompanied by an opinion of counsel reasonably satisfactory to
the Company stating that such transfer is exempt therefrom under such Act and
under any applicable state securities laws."

     Purchaser has carefully read this letter and has discussed its requirements
and other applicable limitations upon Purchaser's resale of the Common Stock
with Purchaser's counsel.



                               Very truly yours,


                               RNH HOLDING LTD.

                               By:    ______________________________
