          ---------------------------------------------
Schedule 1 attached hereto, the Company represents and warrants to Purchaser as
of the date hereof as follows:

          4.1  Organization and Standing.  The Company has been duly
               -------------------------
incorporated and is validly existing as a corporation in good standing under the
laws of the State of Delaware and has all requisite corporate power and
authority to conduct its business as described in the Company's Annual Report on
Form 10-K for the year ended December 31, 2000 filed with the Securities and
Exchange Commission (the "SEC").  The Company is qualified to do business as a
foreign corporation in the Commonwealth of Pennsylvania and there are no other
jurisdictions in which its ownership or lease of property or conduct of its
business requires such qualification, except where the failure to be so
organized or in good standing would not be reasonably likely to have a material
adverse effect on the business, financial condition or results of operations of
the Company.

          4.2  Authorized and Issued Capital Stock.  The authorized capital
               -----------------------------------
stock of the Company, upon the filing of the Certificate of Designations, will
consist of (i) 45,000,000 shares of common stock, par value $.002 per share (the
"Common Stock"), of which 32,543,886 shares are outstanding, and (ii) 9,211,031
shares of preferred stock, $.001 par value per share (the "Preferred Stock"), of
which (a) 80,000 shares have been designated "Series A Convertible Preferred
Stock," and of which 1,188 shares are issued and outstanding as of the date
hereof, and (b) 10,000 shares have been designated "Series B Convertible
Preferred Stock." The Series B Preferred Stock shall have the rights,
preferences, privileges and restrictions set forth in the Certificate of
Designations. Immediately prior to the Closing, there are no outstanding shares
of Series B Preferred Stock. All of the outstanding shares of Common Stock and
Preferred Stock were duly authorized and validly issued and are fully paid and
non-assessable shares. The Company has reserved 10,000 shares of Series B
Preferred Stock for issuance hereunder and 2,000,000 shares of Common Stock for
issuance upon conversion of the Series B Preferred Stock (the "Conversion
Shares"). Except as disclosed in the SEC Documents (as defined herein), there

                                       3
<PAGE>

are no options, warrants or other rights to purchase or acquire any of the
Company's authorized and unissued capital stock.

          4.3  Due Authorization, Execution, Delivery and Performance of the
               -------------------------------------------------------------
Agreements.  The execution, delivery and performance of the Agreements by the
----------
Company, including, but not limited to, the issuance and sale of the Shares and
the issuance of the Conversion Shares in accordance with the provisions of the
Certificate of Designations, (i) have been duly authorized by all requisite
corporate action by the Company, including by its directors and shareholders to
the extent required under the Delaware General Corporation Law, and (ii) will
not violate (a) any law or the Certificate of Incorporation, as amended (the
"Certificate of Incorporation") or the Amended and Restated Bylaws (the
"Bylaws") of the Company, or (b) any provision of any indenture, mortgage,
agreement, contract or other instrument to which the Company is a party or by
which the Company or any of its properties or assets is bound as of the date
hereof, or result in a breach of or constitute (upon notice or lapse of time or
both) a default under any such indenture, mortgage, agreement, contract or other
instrument or result in the creation or imposition of any lien, security
interest, mortgage, pledge, charge or other encumbrance, of any material nature
whatsoever, upon any properties or assets of the Company, except where any such
breach, default, lien or encumbrance would not be reasonably likely to have a
material adverse effect on the business, financial condition or results of
operations of the Company. The Company has no subsidiaries and does not own or
control any equity interest in any corporation, association or other business
entity. Upon their execution and delivery, and assuming the valid execution
thereof by the Purchaser, the Agreements will constitute valid and binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
creditors' and contracting parties' rights generally and except as
enforceability may be subject to general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law)
and except as the indemnification and contribution agreements of the Company in
Section 6.3 hereof may be legally unenforceable.

          4.4  Issuance, Sale and Delivery of the Shares and the Conversion
               ------------------------------------------------------------
Shares.  When issued and paid for, the Shares to be sold hereunder by the
------
Company will be validly issued and outstanding, fully paid and non-assessable,
free and clear of any liens, charges, claims or other encumbrances. When issued
in compliance with the provisions of the Certificate of Designation, the
Conversion Shares will be validly issued and outstanding, fully paid and non-
assessable, free and clear of any liens, charges, claims or other encumbrances.
The Shares and the Conversion Shares shall not entitle the holders of the
outstanding capital stock of the Company to preemptive, anti-dilutive or other
rights to subscribe to or acquire Common Stock or other securities of the
Company; provided, however, that the Shares and the Conversion Shares will be
         --------  -------
subject to restrictions on transfer under state or federal securities laws and
restrictions set forth in Section 6 hereof.

          4.5  Exemption from Registration.  Assuming the accuracy of the
               ---------------------------
Purchaser's representations and warranties set forth in Section 5 hereof, the
offer, issuance and sale of the Shares pursuant to this Agreement will be exempt
from the registration and prospectus delivery requirements of the Securities Act
of 1933, as amended (together with the rules and regulations promulgated
thereunder, the "Securities Act").

          4.6  Intellectual Property.  The Company has title and ownership of,
               ---------------------
or rights to use, all patents, trademarks, service marks, trade names,
copyrights, trade secrets, information, proprietary rights and processes
necessary for its business as now conducted without any conflict with or
infringement of the rights of others, except as would not have a material
adverse effect on the Company. Except as set forth in Schedule 1 hereof and
except for the Ludwig License Agreements (as such term is defined in the
Collaboration and License Agreement), there are no outstanding options,
licenses, or agreements of any kind relating to the subject of the Collaboration
and License Agreement and the transactions and the research contemplated by the
Collaboration and License Agreement, nor is the Company bound by or a party to
any material options, licenses or agreements of any kind with respect to the
patents, trademarks, service marks, trade names, copyrights, trade secrets,
licenses, information, proprietary rights and processes of any other person or
entity. The Company has not received any communications alleging that the
Company has violated or, by conducting its business as proposed, would violate
any of the patents, trademarks, service marks, trade names, copyrights or trade
proprietary rights of any other person or entity and that management reasonably
believes will have a material adverse effect on the Company. To the best
knowledge of the Company, no other person or entity is infringing or violating
any of the patents, trademarks, service marks, trade names, copyrights, trade
secrets, information, proprietary rights and processes necessary for the
Company's business as now conducted. To the best knowledge of the Company, none
of its employees is obligated under any contract (including licenses, covenants
or commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of his or her best efforts to promote the interests of the Company or
that would conflict with the Company's business as proposed to be conducted.
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 proposed, will, to the best of the Company's knowledge,
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
the Company or any of such employees is now obligated except as would not have a
material adverse effect on the Company. The Company does not believe it is or
will be necessary to utilize any inventions of any of its employees (or people
it currently intends to hire) made prior to their employment by the Company.

          4.7  Litigation.  There are no actions, suits, proceedings or
               ----------
investigations pending or, to the Company's knowledge, threatened against the
Company or its properties before any court or governmental agency which
management believes is likely to have a material adverse effect on the Company.
The foregoing includes, without limitation, actions pending or threatened
involving the prior employment of any of the Company's employees, their use in
connection with the Company's business of any information or techniques
allegedly proprietary to any of their former employers, or their obligations
under any agreements with prior employers. The Company is not a party or subject
to the provisions of any order, writ, injunction, judgment or decree of any
court or government agency or instrumentality. There is no action, suit,
proceeding or investigation by the Company currently pending or which the
Company intends to initiate.

          4.8  Material Agreements.  All of the contracts and agreements to

December 31, 2000. Any contracts and agreements to which the Company became a
party between January 1, 2001 and the date hereof and which the Company

respects, subject to laws of general application relating to bankruptcy,
insolvency and the relief of debtors and rules of law governing specific
performance, injunctive relief or other equitable remedies, and the Company has
not received any indication of an intention to terminate any such contract or
agreement by any of the parties to any such contract or agreement.

          4.9  Additional Information.  The Company represents and warrants that
               ----------------------
the information contained in the following documents (the "SEC Documents"),
copies of which have been furnished to the Purchaser, was true and correct in

                                       8
<PAGE>

Company contained herein, as well as any investigation of the Company completed
by the Purchaser or its counsel, accountants or other investment advisers; (vi)
the Purchaser is an "accredited investor" within the meaning of Rule 501 of
Regulation D promulgated under the Securities Act; (vii) the address of the
Purchaser set forth on the preamble hereto is the Purchaser's principal business
address, upon which the Company may rely for the purpose of complying with
applicable "Blue Sky" laws; and (viii) the Purchaser is able to bear the
economic risk of an investment in the Shares.

          5.2  The Purchaser will not, directly or indirectly, offer, sell,
pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase
or otherwise acquire or take a pledge of) any of the Shares or the Conversion
Shares, except in compliance with the Securities Act, and the rules and
regulations promulgated thereunder and by the provisions of Section 6 hereof.
Prior to conversion of all the Shares into the Conversion Shares in accordance
with the Certificate of Designations, Purchaser represents that it will not have
any short positions in the Company's Common Stock and will not deliver
Conversion Shares to cover any short positions taken prior to such conversion of
all the Shares. The Purchaser hereby covenants not to make any sale of the
Conversion Shares under a Registration Statement without effectively causing the
prospectus delivery requirement under the Securities Act to be satisfied, and
the Purchaser acknowledges and agrees that such Conversion Shares that are to be
resold by Purchaser pursuant to a Registration Statement are not transferable on
the books of the Company unless the certificate submitted to the transfer agent
evidencing the Conversion Shares is accompanied by a separate officer's
certificate: (i) in the form of Appendix II hereto, (ii) executed by an officer
                                -----------
of the Purchaser or by an authorized person designated by the Purchaser, and
(iii) to the effect that (A) the Conversion Shares have been sold pursuant to
and in accordance with the Registration Statement and (B) the requirement of
delivering a current prospectus has been satisfied.  The Purchaser acknowledges
that there occasionally may be times when the Company must, subject to the
limitations set forth below in this Section 5.2 and in Section 6.1(viii)(F)
herein, suspend the use of the prospectus forming a part of a Registration
Statement until such time as an amendment to such Registration Statement has
been filed by the Company and declared effective by the Securities and Exchange
Commission, or until such time as the Company has filed an appropriate report
with the Commission pursuant to the Exchange Act.  The Purchaser hereby
covenants that it will not sell any Conversion Shares pursuant to said
prospectus during the period commencing at the time at which the Company gives
the Purchaser notice of the suspension of the use of said prospectus and ending
at the time the Company gives the Purchaser notice that the Purchaser may
thereafter effect sales pursuant to said prospectus.  The Company shall only be
able to suspend the use of said prospectus for two periods aggregating no more
than ninety (90) business days in any twelve-month period, of which no
individual period shall be longer than forty-five (45) consecutive days;
provided, however, that in no event shall the aggregate number of days pursuant
to which the Company may suspend the use of a prospectus pursuant to this
Section 5.2 and delay an underwritten public offering pursuant to Section
6.1(viii)(F) herein exceed one hundred twenty (120) days in any twelve-month
period.  The Purchaser further covenants to notify promptly the Company of the
sale of all of its Conversion Shares.

          5.3  The Purchaser understands that although there currently is a
public market for its Common Stock, Rule 144 promulgated under the Act ("Rule
144") requires, among other conditions, a one-year holding period prior to the
resale (in limited amounts) of securities

                                       9
<PAGE>

acquired in a non-public offering without having to satisfy the registration
requirements under the Act. The Purchaser understands and hereby acknowledges
that the Company is under no obligation to register the Shares or the Conversion
Shares under the Act or any state securities or "Blue Sky" laws other than as
set forth in Section 6 hereof. The Purchaser agrees to hold the Company and its
directors, officers, employees, controlling persons and agents and their
respective heirs, representatives, successors and assigns harmless and to
indemnify them against all liabilities, costs and expenses incurred by them as a
result of (i) any misrepresentation made by the Purchaser contained in this
Agreement (including Appendix I and Appendix II herein), (ii) any sale or
                     ----------     -----------
distribution by the Purchaser in violation of the Act or any applicable state
securities or "Blue Sky" laws or (iii) any untrue statement of a material fact
made by the Purchaser and contained herein.

          5.4  The Purchaser hereby consents to and understands that the Shares
shall bear a restrictive legend in substantially the following form (and a stop-
transfer order may be placed against transfer of the certificates for such
securities):

          "The Shares represented by this certificate have been
          acquired for investment and have not been registered
          under the Securities Act of 1933. The Shares may not be
          sold or transferred in the absence of such registration
          or exemption therefrom.

          The Shares represented by this certificate and the
          rights of holders thereof are subject to certain
          restrictions on transfer and other restrictions, and
          the holder of the Shares represented by this
          certificate (including any holders) are bound by the
          terms of restrictions set forth in the Preferred Stock
          Purchase Agreement between the original Purchaser and
          the Company (copies of which may be obtained from the
          Company)."

          5.5  The Purchaser further represents and warrants to, and covenants
with, the Company that (i) the Purchaser has full right, power, authority and
capacity to enter into the Agreements and to consummate the transactions
contemplated thereby and has taken all necessary action to authorize the
execution, delivery and performance of the Agreements, and (ii) upon the
execution and delivery of the Agreements, the Agreements shall constitute a
valid and binding obligation of the Purchaser enforceable in accordance with
their terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors' and
contracting parties' rights generally and except as enforceability may be
subject to general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

          5.6  No representation or warranty made by the Purchaser in this
Agreement, any schedule or exhibit hereto, or any certificate delivered
hereunder, when taken together, contains any untrue statement of a material
fact, or omits to state a material fact necessary to make the statements
contained herein or therein not misleading in light of the circumstances under
which they were made.

          6.1  Registration Procedures and Expenses.
               ------------------------------------

               (i)   The Company shall as soon as practicable, but in no event
          later than May 31, 2001, prepare and file with the Commission a
          Registration Statement on Form S-3 (or if such form is unavailable to
          the Company, on such other form deemed appropriate for the
          registration of the Common Stock by the Commission) (the "Initial
          Registration Statement") to register up to two million (2,000,000)
          shares of the Conversion Shares for resale by the Purchaser
          ("Registrable Securities") and such Initial Registration Statement
          shall include the Plan of Distribution section set forth in Appendix I
                                                                      ----------
          hereof, and shall use commercially reasonable efforts to cause the
          Initial Registration Statement to become effective as soon as
          practicable thereafter; provided that the Company shall be obligated
          to include in the Initial Registration Statement or the Subsequent
          Registration Statement (as defined herein), as the case may be, the
          disposition of Conversion Shares held by a Record Transferee (as
          defined herein) only if the Purchaser transferring any Conversion
          Shares to a third party (the "Record Transferee") gives notice of such
          transfer to the Company and any such Record Transferee agrees in
          writing to be bound by the provisions of Section 7 hereof and this
          Section 6; if the Purchaser converts the Shares into Conversion Shares
          at any time following the fifth anniversary of the date hereof and the
          number of such Conversion Shares is in excess of two million
          Conversion Shares, the Company shall as soon as practicable following
          such conversion prepare and file with the Commission a second
          Registration Statement to register such excess Conversion Shares for
          resale by the Purchaser (the "Subsequent Registration Statement,"
          together with the Initial Registration Statement, the "Registration
          Statements" and, individually, a "Registration Statement"), and shall
          use commercially reasonable efforts to cause the Subsequent
          Registration Statement to become effective as soon as practicable
          thereafter;

               (ii)  The Company shall promptly prepare and file with the
          Commission such amendments and supplements to a Registration Statement
          and the prospectus used in connection therewith as may be necessary to
          keep such Registration Statement effective until the first to occur of
          (a) such date when either all of the Registrable Securities have been
          sold pursuant thereto or, by reason of Rule 144(k) of the Commission
          under the Securities Act or any other rule of similar effect, the
          Registrable Securities are no longer required to be registered for the
          sale thereof by the Purchasers in ordinary market transactions without
          imposition of any volume, manner of sale or other limitations, or (b)
          the second anniversary of the Closing Date (the "Registration
          Period");

               (iii) The Company shall promptly furnish to the Purchaser such
          number of copies of prospectuses in conformity with the requirements
          of the Securities Act and such other documents as the Purchaser may
          reasonably request, in order to facilitate the public sale or other
          disposition of all or any of the Registrable Securities by the
          Purchaser;

                                       11
<PAGE>

               (iv)   The Company shall promptly file documents required of the
          Company for normal "Blue Sky" clearance for the disposition by the
          Purchaser and any Record Transferees of the Registrable Securities in
          such states as the Purchaser may reasonably request in writing to the
          Company, provided however, that the Company shall not be required (i)
          to qualify to do business or consent to service of process in any
          jurisdiction in which it is not now so qualified or has not so
          consented; (ii) subject itself to general taxation in any such
          jurisdiction; (iii) provide any undertakings that cause the Company
          undue expense or burden; or (iv) make any change in its charter or
          bylaws;

               (v)    The Company shall promptly inform the Purchaser when any
          stop order has been issued with respect to a Registration Statement
          and use commercially reasonable efforts to promptly cause such stop
          order to be withdrawn;

               (vi)   Except with respect to an underwritten offering as set
          forth in Section 6.1(viii) hereof, the Company shall bear all expenses
          in connection with the procedures in paragraphs (i) through (v) of
          this Section 6.1 and the registration of the Registrable Securities,
          other than fees and expenses, if any, of counsel or other advisers to
          the Purchaser or the other Purchasers and any expenses relating to the
          sale of the Registrable Securities by the Purchasers (including
          without limitation, broker's commissions, discounts or fees of any
          nature and transfer taxes or changes of any nature); and

               (vii)  A Questionnaire related to the Registration Statements to
          be completed by the Purchaser, including the Purchaser's approval of
          the "Plan of Distribution" section of the Registration Statement is
          attached as Appendix I to this Agreement.  The Company may amend the
                      ----------
          Plan of Distribution section as necessary to comply with the
          requirements of the Commission, provided, that, the Company shall send
                                          --------  ----
          any such amendments to the Purchaser at least two (2) business days
          prior to the filing of the Registration Statement with the Commission
          for the Purchaser's approval, which shall not be unreasonably withheld
          and, in the absence of written objection prior to filing, shall be
          deemed to be an approval by the Purchaser of such amended section.

               (viii) Recognizing that an underwritten public offering of the
          Conversion Shares may be mutually beneficial to the Company and the
          Purchaser, the Company agrees that if the Purchaser determines to sell
          the Conversion Shares by means of an underwritten public offering, the
          Company agrees to cooperate with the Purchaser and the underwriter to
          effectuate an underwritten offering, including entering into an
          underwriting agreement, subject to the following conditions and
          limitations:

                      (A)  the Purchaser shall only be permitted to effect the
          resale of Conversion Shares through one (1) underwritten offering;

                                       12
<PAGE>

                    (B)  the underwriter selected by the Purchaser shall be
          reasonably acceptable to the Company and the Company shall not be
          required to execute an underwriting agreement unless and until it
          determines in its reasonable judgment that the terms of such
          underwriting agreement are customary for transactions of that size and
          type;

                    (C)  the Company shall have the ability to include shares of
          Common Stock to be sold on its behalf in the offering subject to
          approval by the underwriters; if the total amount of shares of Common
          Stock  requested by the Company to be included in the offering exceeds
          the amount of securities that the underwriters determine is compatible
          with the success of the offering, then only such number of shares of
          Common Stock to be sold on the Company's behalf shall be included as
          the underwriters determine will not jeopardize the success of the
          offering;

                    (D)  the registration of the Conversion Shares to be offered
          in the underwriting shall be on the Registration Statement;

                    (E)  the Purchaser shall not be permitted to resell
          Conversion Shares pursuant to an underwritten offering until it has
          converted all of its Shares and unless such offering is for at least
          75% of the aggregate Conversion Shares issued to Purchaser pursuant to
          all of its conversions of Shares;

                    (F)  the Company shall be permitted to delay an underwritten
          offering requested by Purchaser once in any twelve month period for a
          period not to exceed ninety (90) days if the Board of Directors of the
          Company determines that it would be detrimental to effect such an
          underwritten offering at such time; provided, however, that in no
          event shall the aggregate number of days pursuant to which the Company
          may suspend the use of a prospectus pursuant to Section 5.2 herein and
          delay an underwritten public offering pursuant to this Section
          6.1(viii)(F) exceed one hundred twenty (120) days in any twelve-month
          period;

          In connection with an underwritten offering of the Conversion Shares
          under this Section 6.1(viii), (i) Purchaser and Company agree to
          equally split any and all incremental accounting fees and expenses and
          printing costs attributable solely to the underwritten offering, (ii)
          Purchaser agrees to bear any and all discounts, concessions,
          commissions or other compensation to be received by the underwriters,
          and (iii) each party hereto agrees to bear their respective counsel
          fees and expenses.

          6.2  Transfer of Shares After Registration.  The Purchaser agrees that
               -------------------------------------
it will not effect any disposition of the Shares that would constitute a sale
within the meaning of the Securities Act except as contemplated in a
Registration Statement or as otherwise in compliance with applicable securities
laws and that it will promptly notify the Company of any material changes in the
information set forth in a Registration Statement regarding the Purchaser or its
plan of distribution. The Company agrees to notify each Purchaser whose
Registrable Securities are registered on a Registration Statement and its agent
at any time when a prospectus relating to

                                       13
<PAGE>

any Registrable Securities covered by such Registration Statement is required to
be delivered under the Securities Act of the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing, and to
promptly file such amendments and supplements as may be necessary so that, as
thereafter delivered to such Purchasers of such Registrable Securities, such
prospectus shall not include an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in light of the circumstances then existing
and use commercially reasonable efforts to cause each such amendment and
supplement to become effective.

          6.3  Indemnification and Contribution.  For the purpose of this
               --------------------------------
Section 6.3, the term "Selling Stockholder" shall include the Purchaser, its
officers, directors, and/or trustees and any affiliate or controlling person of
such Purchaser or any permitted assign hereunder; and the term "untrue
statement" shall include any untrue statement or alleged untrue statement, or
any omission or alleged omission to state in a Registration Statement a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

               (i)  The Company agrees to indemnify and hold harmless each
          Selling Stockholder from and against any losses, claims, damages or
          liabilities to which such Selling Stockholder may become subject
          (under the Securities Act or otherwise) insofar as such losses,
          claims, damages or liabilities (or actions or proceedings in respect
          thereof) arise out of, or are based upon, any breach of the
          representations set forth in Section 4 hereof by the Company, or any
          untrue statement of a material fact contained in a Registration
          Statement, or arise out of any failure by the Company to fulfill any
          agreement, covenant or undertaking contained in this Agreement or
          included in a Registration Statement, and the Company will reimburse
          such Selling Stockholder for any reasonable legal or other expenses
          reasonably incurred in investigating, defending or preparing to defend
          any such action, proceeding or claim; provided, however, that the
                                                --------  -------
          Company shall not be liable in any such case if such loss, claim,
          damage or liability arises out of, or is based upon, (i) an untrue
          statement made in a Registration Statement in reliance upon and in
          conformity with written information furnished to the Company by or on
          behalf of such Selling Stockholder specifically for use in preparation
          of a Registration Statement (which shall be deemed to include the
          information set forth in the Registration Statement Questionnaire and
          in the plan of distribution section of the prospectus), (ii) the
          failure of such Selling Stockholder to comply with the covenants and
          agreements contained herein respecting transfer or sale of the Shares,
          including, but not limited to, the Purchaser's covenant in Section 5.2
          hereof to comply with the prospectus delivery requirements under the
          Securities Act, or (iii) any statement or omission in any Prospectus
          that is corrected in any subsequent Prospectus that was delivered to
          the Purchaser prior to the pertinent sale or sales by the Purchaser.
          The Company shall also not be liable for amounts paid in settlement of
          any loss, claim, damage or liability if such settlement is effected
          without the prior written

                                       14
<PAGE>

          consent of the Company, which consent shall not be unreasonably
          withheld or delayed.

               (ii)  The Purchaser agrees to indemnify and hold harmless the
          Company (and each person, if any, who controls the Company within the
          meaning of Section 15 of the Securities Act, each officer of the
          Company who signs the Registration Statement and each director of the
          Company) from and against any losses, claims, damages or liabilities
          to which the Company (or any such officer, director or controlling
          person) may become subject (under the Securities Act or otherwise),
          insofar as such losses, claims, damages or liabilities (or actions or
          proceedings in respect thereof) arise out of, or are based upon, any
          breach of the representations set forth in Section 5 hereof by the
          Purchaser, or any failure by the Purchaser to comply with the
          covenants and agreements contained herein relating to transfer or sale
          of the Shares, including, but not limited to, the Purchaser's covenant
          in Section 5.2 hereof to comply with the prospectus delivery
          requirements under the Securities Act,  or any untrue statement of a
          material fact contained in a Registration Statement if such untrue
          statement was made in reliance upon and in conformity with written
          information furnished by or on behalf of the Purchaser specifically
          for use in a Registration Statement.  The Purchaser will reimburse the
          Company (or such officer, director or controlling person), as the case
          may be, for any legal or other expenses reasonably incurred in
          investigating, defending or preparing to defend any such action,
          proceeding or claim.  The Purchaser agrees that the information
          regarding the Purchaser or its officers, directors and affiliates and
          their intended plan of distribution of the Conversion Shares set forth
          in a Registration Statement questionnaire, the form of which is
          attached as Appendix I, or included from time to time in a
                      ----------
          Registration Statement (including without limitation the plan of
          distribution section of such Registration Statement) shall be deemed
          to be written information furnished to the Company by or on behalf of
          the Purchaser specifically for use in preparation of a Registration
          Statement.  The foregoing indemnification shall be limited in amount
          to the aggregate purchase price paid by the Purchaser hereunder.  The
          Purchaser shall also not be liable for amounts paid in settlement of
          any loss, claim, damage or liability if such settlement is effected
          without the prior written consent of the Purchaser, which consent
          shall not be unreasonably withheld or delayed.

               (iii) Promptly after receipt by any indemnified person of a
          notice of a claim or the beginning of any action in respect of which
          indemnity is to be sought against an indemnifying person pursuant to
          this Section 6.3, such indemnified person shall notify the
          indemnifying person in writing of such claim or of the commencement of
          such action; provided, however, that any failure by an indemnified
                       --------  -------
          person to notify an indemnifying person shall not relieve the
          indemnifying person from its obligations hereunder except to the
          extent that the indemnifying person is prejudiced thereby.  Subject to
          the provisions hereinafter stated, in case any such action shall be
          brought against an indemnified person and such indemnifying person
          shall have been notified thereof, such indemnifying person shall be
          entitled to participate therein, and, to the extent it shall wish, to
          assume and control the defense thereof, with counsel reasonably
          satisfactory to

                                       15
<PAGE>

          such indemnified person. After notice from the indemnifying person to
          such indemnified person of its election to assume the defense thereof,
          such indemnifying person shall not be liable to such indemnified
          person for any legal expenses subsequently incurred by such
          indemnified person in connection with the defense thereof; provided,
                                                                     --------
          however, that if there exists a conflict of interest that would make
          -------
          it inappropriate, in the opinion of counsel to the indemnifying
          person, for the same counsel to represent both the indemnified person
          and such indemnifying person or any affiliate or associate thereof,
          the indemnified person shall be entitled to retain its own counsel at
          the expense of such indemnifying person; provided further, however,
                                                   -------- -------  -------
          that no indemnifying person shall be responsible for the fees and
          expenses of more than one separate counsel for all indemnified parties
          hereunder and under the other Agreements.

               (iv) If the indemnification provided for in this Section 6.3 from
          the indemnifying person would be applicable by its terms but is
          otherwise unavailable, as determined by a court of applicable
          jurisdiction, to an indemnified person hereunder in respect of any
          losses, claims, damages, liabilities or expenses referred to herein,
          then the indemnifying person, in lieu of indemnifying such indemnified
          person, shall contribute to the amount paid or payable by such
          indemnified person as a result of such losses, claims, damages,
          liabilities or expenses in such proportion as is appropriate to
          reflect the relative fault of the indemnifying person and indemnified
          persons in connection with the actions which resulted in such losses,
          claims, damages, liabilities or expenses, as well as any other
          relevant equitable considerations.  The relative fault of such
          indemnifying person and indemnified persons shall be determined by
          reference to, among other things, whether any action in question,
          including any untrue or alleged untrue statement of a material fact,
          has been made by, or relates to information supplied by, such
          indemnifying person or indemnified persons, and the parties' relative
          intent, knowledge, access to information and opportunity to correct or
          prevent such action.  The amount paid or payable by a party as a
          result of the losses, claims, damages, liabilities and expenses
          referred to above shall be deemed to include, subject to the
          limitations set forth in this Section 6.3, any reasonable legal or
          other fees or expenses reasonably incurred by such party in connection
          with any investigation or proceeding.

               (v)  The parties hereto agree that it would not be just and
          equitable if contribution pursuant to this Section 6.3 were determined
          by pro rata allocation or by any other method of allocation which does
          not take account of the equitable considerations referred to in the
          immediately preceding paragraph.  Notwithstanding the provisions of
          this Section 6.3, Purchaser shall not be required to contribute any
          amount in excess of the dollar amount of the proceeds received by
          Purchaser upon the sale of the Conversion Shares, giving rise to such
          contribution obligation.  No person guilty of fraudulent
          misrepresentation (within the meaning of Section 11(f) of the
          Securities Act) shall be entitled to contribution from any person who
          was not guilty of such fraudulent misrepresentation.

                                       16
<PAGE>

               (vi) The indemnification and contribution provided in this
          Section 6.3 shall be in addition to any other rights and remedies
          available at law or in equity.

     7.   Compliance.  With a view to making available to Purchaser the benefits
          ----------
of Rule 144 promulgated under the Securities Act, the Company agrees:

          7.1  So long as Purchaser or any subsequent holder(s) of the Shares,
or the Conversion Shares, own the Shares, or the Conversion Shares, promptly
upon request, to furnish to such owner such information as may be necessary and
otherwise reasonable to cooperate with such owner to permit such owner to sell
the Conversion Shares pursuant to Rule 144 without registration.

          7.2  If at any time the Company is not required to file reports with
the SEC pursuant to Sections 13 or 15(d) of the Exchange Act, to use
commercially reasonable efforts to, upon the request of Purchaser or any
subsequent holder(s) of any of the Shares or the Conversion Shares, to make
publicly available other information so long as is necessary to permit
publication by brokers and dealers of quotations for the Common Stock and sales
of the Conversion Shares in accordance with Rule 15c2-11 under the Exchange Act.

                             PLAN OF DISTRIBUTION

          To the extent required, the names of any agent or broker-dealer and
applicable commissions or discounts and any other required information with
respect to any particular offer will be set forth here or in the accompanying
prospectus supplement.  The selling stockholders reserve the sole right to
accept or reject, in whole or in part, any proposed purchase of the shares to be
made directly or through agents.

          The selling stockholder may from time to time, in one or more
transactions, sell all or a portion of the shares on the Nasdaq National Market,
in negotiated transactions, in underwritten transactions or otherwise, at prices
then prevailing or related to the then current market price or at negotiated
prices.  The offering price of the shares from time to time will be determined
by the selling stockholder and, at the time of such determination, may be higher
or lower than the market price of the shares on the Nasdaq National Market.  In
connection with an underwritten offering, underwriters or agents may receive
compensation in the form of discounts, concessions or commissions from a selling
shareholder or from purchasers of shares for whom they may act as agents, and
underwriters may sell shares to or through dealers, and such dealers may receive
compensation in the form of discounts, concessions or commissions from the
underwriters and/or commissions from the purchasers for whom they may act as
agents.  Under agreements that may be entered into by us, underwriters, dealers
and agents who participate in the distribution of shares may be entitled to
indemnification by us against certain liabilities, including liabilities under
the Securities Act, or to contribution with respect to payments which such
underwriters, dealers or agents may be required to make in respect thereof.  The
shares may be sold directly or through broker-dealers acting as principal or
agent, or pursuant to a distribution by one or more underwriters on a firm
commitment or best-efforts basis.  The methods by which the shares may be sold
include:

 .    a block trade in which the broker-dealer so engaged will attempt to sell
     the shares as agent but may position and resell a portion of the block as
     principal to facilitate the transaction;

 .    purchases by a broker-dealer as principal and resale by such broker-dealer
     for its account pursuant to this prospectus;

 .    ordinary brokerage transactions and transactions in which the broker
     solicits purchasers;

 .    privately negotiated transactions; and

 .    underwritten transactions.

          The selling stockholder and any underwriters, dealers or agents
participating in the distribution of the offered shares may be deemed to be
"underwriters" within the meaning of the Securities Act, and any profit on the
sale of the shares by the selling stockholder and any commissions received by
these broker-dealers may be deemed to be underwriting commissions under the
Securities Act.

                                      I-3
<PAGE>

     When the selling stockholder elects to make a particular offer of shares, a
prospectus supplement, if required, will be distributed which will identify any
underwriters, dealers or agents and any discounts, commissions and other terms
constituting compensation from the selling stockholder and any other required
information.

     In order to comply with the securities laws of certain states, if
applicable, the shares may be sold only through registered or licensed brokers
or dealers.  In addition, in certain states, the shares may not be sold unless
they have been registered or qualified for sale in such state or an exemption
from such registration or qualification requirement is available and is complied
with.

     We have agreed to pay all costs and expenses incurred in connection with
the registration under the Securities Act of the shares, including, without
limitation, all registration and filing fees, fees and disbursements of our
counsel and certain accounting and printing costs.  The selling stockholder will
pay any brokerage fees and commissions, fees and disbursements of legal counsel
for the selling stockholder and stock transfer and other taxes attributable to
the sale of the shares.  We also have agreed to indemnify the selling
stockholder and its respective officers, directors and trustees and each person
who "controls," within the meaning of the Securities Act, the selling
stockholder against certain losses, claims, damages, liabilities and expenses
arising under the securities laws in connection with this offering.  The selling
stockholder has agreed to indemnify us, our officers and directors and each
person who "controls" Genaera Corporation against any losses, claims, damages,
liabilities and expenses arising under the securities laws in connection with
this offering with respect to written information furnished to us by such
selling stockholder.

2.    RIGHTS GRANTED TO BSP

2.01  Right to Market, Sell and License Products and Services. "Affiliate" shall
mean entities that are directly or indirectly controlled by BSP as each are
identified on the attached Schedule F to this Agreement. "Controlled" means that
BSP owns, directly or indirectly, more than fifty percent of the outstanding
common stock of the Affiliate. BSP agrees to undertake to provide RIM at least
thirty days prior notice of any Affiliate that is no longer controlled by BSP,
in which case such Affiliate's rights under this Section 2.01 shall immediately
terminate. BSP may also, upon acquiring a new Affiliate, request that RIM
consent to amend Schedule F, which consent shall be granted unless doing so
would cause RIM to breach an agreement between RIM and a third party, and
provided, however, that BSP shall remain liable and obligated hereunder for the
acts or omissions of such new Affiliates. Upon receipt and acceptance by RIM of
the Initial Order and, subject to the terms and conditions of this Agreement and
RIM's Standard Terms and Conditions of Sale included in Schedule C, RIM hereby
grants to BSP and its Affiliates a nonexclusive, nontransferable right within
the Territory to market, distribute, demonstrate, purchase for resale, renting
and/or licensing, as the case may be, the Products and Services. BlackBerry
Software is licensed, not sold. Neither BSP nor any Affiliate shall market,
sell, rent, lease, license or distribute the Products or Services except as
specifically permitted by this Agreement. Notwithstanding anything herein to the
contrary, BSP may authorize its Affiliates and those of its resellers of other
BSP products and services offered under BSP's name to market, distribute,
demonstrate, purchase for resale, renting and/or licensing, as the case may be,
the Products and Services, provided BSP informs RIM of the name, address and
website of each such reseller prior to BSP authorizing such activities by the
reseller; however, RIM shall not use such information for other then legitimate
purposes and RIM shall not contact such Affiliates or resellers with a view to
soliciting a direct contractual relationship with RIM. Purchases of Products by
Affiliates and authorized resellers shall count toward BSP's Volume Commitment.
The Parties agree to work together to establish a process by which BSP's
resellers may be authorized by RIM to purchase Products, directly from RIM where
such purchases will be counted toward BSP's Volume Commitment.

2.02  Marketing Practices. In marketing the Products and Services the BSP shall:
(a) avoid deceptive, misleading, illegal, or unethical practices that may be
detrimental to RIM or to the Products and Services; (b) not make any
representations, warranties, or guarantees to End-Users concerning the Products
and Services that purport to obligate RIM or that are inconsistent with those
made in this Agreement, the applicable Software License Agreement, the User's
Manual (defined as the BSP user guide developed by RIM in furtherance of the BSP
program), the RIM approved BSP Order Form, the BlackBerry End-User Agreement or
otherwise by reference to RIM's web site(s) or, if provided in writing by RIM;
and (c) comply with all applicable federal, state, provincial, and local laws
and regulations in marketing the Products and Services and in performing its
duties with respect to the Products and Services, including, without limitation,
the collection of taxes on the sales of Product in any jurisdiction in which the
BSP sells the Product.

2.03  Co-op and Marketing Development Funds. For as long as BSP fulfills its
obligation under Article 3 below, abides by the terms and conditions of this
Agreement, and subject to the requirements of the Co-op Marketing and
Development Program (attached as Schedule D), for each Product purchased by BSP,
RIM shall set aside marketing funds for use by BSP, in accordance with the terms
and conditions of RIM's current Co-op Marketing and Development Program, in its
marketing efforts associated with its distribution and promotion of the
Products. The funds shall be accrued in BSP's marketing fund account upon
receipt of payment for Products shipped. Should this Agreement be terminated for
any reason, any marketing funds accumulated by the BSP shall be applied to
amounts due to BSP as relates to RIM approved marketing efforts, or if no
amounts are due to BSP, shall revert back to RIM.

2.04  Limitations on Use. The BSP shall not use or duplicate the Products or
Services (including the Documentation) for any purpose other than as specified
in this Agreement or make the Products and Services available to unauthorized
third parties. The BSP may not use the Products and Services unless: (a) the BSP
purchases and/or licenses the Products and Services, as applicable, specifically
for internal or demonstration use, or (b) otherwise provided herein. Any product
used for demonstration purposes may not be resold as a "new" Product. The resale
of any demonstration Product by BSP as a "new" Product shall be considered a
material breach of this Agreement. Except as may be permitted by law, the BSP
agrees not to cause or permit the reverse engineering, disassembly, or
decompilation of the Products. Should it become known to the BSP that an
End-User has attempted to reverse engineer, disassemble or decompile the
Products, the BSP shall immediately notify RIM and direct such End-User to
contact RIM directly. The BSP shall be entitled to use the Products and/or
Services to develop and market applications for use with the Products and/or
Services, as applicable, provided that (a) such applications do not use RIM's
airlink, (b) BSP states clearly in all applicable marketing material that RIM
does not warrant, and bears no responsibility, for such application, and (c) BSP
provides RIM with prior written notification of such development and/or
marketing activities.

2.05  Title. Title to and risk of loss or damage to any hardware purchased
hereunder shall pass to BSP upon receipt by BSP. RIM and its suppliers
(including, without limitation, its licensors) shall retain all copyright and
other proprietary rights in the Products, Services and Documentation and any
modifications or translations thereof. The foregoing notwithstanding, BSP shall
have a limited right to any derivations it is permitted to make to the
Documentation to facilitate its resale of Products under the terms of this
Agreement, provided such derivations are provided to RIM for its approval and
review, which approval and review shall not be unreasonably withheld or delayed.
The BSP and the End-User do not acquire any rights, title or interest in the
Products, Services or Documentation other than those rights specified in this
Agreement.

3.    OBLIGATIONS OF THE BSP

In addition to the obligations set forth elsewhere in the Agreement, BSP shall
be responsible for the following specific obligations:

                          Asterisks denote omissions.

3.01  Initial Order. Upon execution of this Agreement by the Parties, the BSP
will complete and submit to RIM a BSP Purchase Order for the Initial Order. The
BSP agrees to purchase and take delivery of the initial quantity of Product as
indicated in the Initial Order subject to the prices and fees as indicated in
Schedule A. The Initial Order, once placed by BSP and accepted by RIM, shall be
non-refundable and irrevocable. The BSP shall take delivery of the Initial Order
in accordance with the Delivery Schedule. The BSP is specifically prohibited
from submitting any purchase order or BSP Purchase Order with any terms and
conditions that are in addition to or that modify or conflict with the terms and
conditions of this Agreement. Should RIM receive such an order, any terms and
conditions that are in addition to or that modify or conflict with the terms and
conditions of this Agreement are hereby rejected without further written notice.

3.02  BSP Order Form. The BSP shall develop a BSP Order Form for Products and
Services and a BSP End-User Agreement that is consistent with this Agreement and
the RIM Blackberry End User Agreement. The BSP Order Form shall include, at a
minimum, the following language on the face of the BSP Order Form substantially
similar to the following:

"This Order Form, in conjunction with the (enter BSP name) End-User Agreement,
constitutes an offer ("Offer") by you or the entity you represent as an
authorized signatory (in either case, "You") to rent and/or buy BlackBerry
Handheld(s) and Services and to license certain associated BlackBerry Software.
Please read this Order Form and the End-User Agreement carefully. By signing
this form, the End-User Agreement becomes a legally-binding contract between You
and (enter name of BSP). In signing the Offer, in addition to the
representations, warranties and agreements You make under the terms of the
End-User Agreements You specifically agree You are authorized to sign for and
bind any account named above."

3.03  Electronic Mail ("Email") Link. If BSP is an Internet service provider,
BSP shall be responsible for the establishment and maintenance of a link between
the BSP Internet Email End-Users and the RIM BlackBerry system that will
automatically forward Email across the Internet to RIM, which Email will then be
processed by RIM and sent on to the End User using the Product.

3.04  Tier I Support. The BSP is specifically responsible for Tier I Support and
shall be the End-User's point of contact. To the extent that the Tier I Support
obligations contained in this Agreement conflict with the provisions of any
other agreement, the Tier I Support obligations contained in this Agreement
shall supersede those terms with which they conflict unless specifically
excluded by such other agreement.

3.05  Training. In order to provide Tier I Support, the BSP is required to have
at least one technical employee of BSP attend a BlackBerry training class at
RIM's headquarters in Waterloo, Ontario Canada or at BSP's site as the Parties
mutually agree. It is the intent of this training to train a limited number of
BSP employees so that such trained BSP employees will be capable of training
additional BSP employees in the use and support of the Products and Services and
be able to provide Tier I Support. Any training beyond that provided above shall
be at BSP's expense for reasonable travel expenses incurred by RIM and subject
to availability of RIM training personnel.

3.06  Minimum Service Requirement. For each BlackBerry Product purchased, the
BSP must purchase a minimum of[**]) months of continuous Service from date of
activation. The purchased Service must be used within [**] months of the
delivery purchase date for such BlackBerry Product.

                          Asterisks denote omissions.

3.07  Service Activation. It is the responsibility of the BSP to request RIM
activate Service related to the purchase, renting, leasing and/or licensing of
any Products at the time of such purchase, rental, lease and for licensing. In
order to activate Service, the BSP shall provide a written request to RIM and
must include information reasonably required by RIM in order to effect the
Service activation. RIM and the BSP agree to work together to explore methods of
activation notification by electronic means, such as by email or through a
dedicated secure website. To facilitate RIM's compliance with limits its
wireless network carrier currently imposes on daily activation volumes, the BSP,
when requesting activations, shall not request to activate more than [**] of the
Products in any one business day, and shall only request activations in
multiples of [**]. If RIM's wireless network carrier increases or eliminates
such limits, RIM shall increase or waive the restriction imposed in the
preceding sentence. RIM will complete its own processing of activation requests
promptly, and will submit all activation requests to its wireless network
carriers as soon as reasonably practicable, subject to any delays beyond RIM's
control, but BSP acknowledges that due to its carrier's processing requirements,
activations may not occur before the [**] business day following the BSP's
activation request.

3.08  Service De-Activation. It is the responsibility of the BSP to notify RIM
in writing to de-activate any Service as may be required for any reason by the
End-User or the BSP. Such notice shall include the information indicated in
Section 3.07 above. The BSP acknowledges and agrees the BSP is solely
responsible for any and all Service fees incurred through the date of such
de-activation. RIM shall not charge BSP a fee to deactivate any Service.

3.09  End-User Fees. It is the responsibility of the BSP to invoice End-Users
for Products and/or Services ordered and to collect any amounts due from such
End-Users. The failure or inability of the BSP to collect any amounts due from
End-Users shall not relieve the BSP from timely payments when due to RIM for
such Products and/or Services.

3.10  Minimum Order Quantity. Following the Initial Order, each subsequent order
for Product shall be in quantity multiples of [**] with no less than [**]
("Lot") per order. Orders for Product quantities of no more than one Lot require
receipt of an order at least [**] days prior to the first delivery date. Orders
for quantities of more than one Lot require receipt of an order at least [**]
days prior to the first delivery date. Delivery schedules shall be as mutually
agreed to in writing. Subject to the percentages indicated below, BSP may
request deferral or cancellation of a scheduled shipment of Products provided
that:

       (a)  in relation to a deferral of a scheduled shipment date for Product
       such deferral will specifically be limited to the original quantity
       scheduled for shipment. Deferral shipment dates may be rescheduled up to
       [**] days later than the originally scheduled shipment date. Deferral
       shipments may not be extended beyond the expiration date of this
       Agreement. However, if the order or any part thereof applicable to the
       rescheduled shipment is subsequently cancelled, the cancellation charges
       indicated herein below will apply based on the original shipment date and
       deferral notice date and will become immediately due and payable. The
       percentages indicated in each row represent the maximum quantity of the
       applicable Product which may be rescheduled, as a percentage of the total
       quantity of that Product originally scheduled for delivery during that
       time period.

       (b)  in relation to the cancellation of Products, BSP may cancel any
       order for Products only upon prior written notice to RIM subject to the
       cancellation charges herein below. BSP may cancel any order within [**]
       hours of issuing without penalty. If the anticipated shipment date of any
       order is delayed by RIM by [**] days or more, BSP may cancel the shipment
       without penalty. The following charges will apply to any cancellation of
       an order or any part of an order cancelled more than [**] hours after the
       issuing of such an order to RIM.

                     Days Notice       Cancellation Charge

                     [**] days         [**]% *
                     [**] days         [**]%*

       Regardless of the notice period given by BSP and in addition to the
       cancellation charges indicated above, BSP shall be responsible for the
       cost of any custom material procured exclusively for this Agreement by
       RIM and still in inventory at the time the cancellation notice is
       submitted to RIM.

3.11   Rolling Forecast. Within thirty (30) days of execution of this Agreement,
BSP shall provide to RIM in writing a [**] day rolling forecast of Product
requirements. Should the Initial Order or any subsequent order include delivery
requirements over a period of [**] days or more, the rolling forecast shall be
extended to include [**] days beyond such order. All forecasts BSP provides
under this Section 3.11 shall be for information purposes only and shall not
bind or commit BSP to the purchase of the forecasted quantities, provided,
however, that BSP shall comply with the provisions of section 3.10 herein.

3.12   Product Packaging. All shipping and handling for the delivery of Products
to a single BSP-designated site shall be at RIM's expense, aggregated with other
Product in bulk. Following the initial unit delivery BSP may change the delivery
site for subsequent deliveries by providing separate written notice to RIM in
accordance with the notice provisions herein. Such change in delivery site shall
be accepted by RIM provided that (a) the new designated delivery site is a
single site and (b) the BSP notification of change of delivery site is the first
such notification following BSP's initial designation of delivery site. All
requested changes in delivery site subsequent to the BSP's first notification of
change of delivery site shall be accepted or rejected at RIM's sole discretion.
Shipping methods shall be at RIM's discretion or as mutually agreed. Unless BSP
and RIM have agreed to co-brand the Products and Services, the BSP may not add,
modify or remove contents or information to or from the RIM-prepared BlackBerry
packaging and shall deliver such Product to End-Users in original factory
condition. Unless BSP and RIM have agreed to co-brand the Products and Services,
Product shall be packaged in standard RIM-prepared packaging.

Notwithstanding the limitation above, at BSP's option, and subject to RIM's
prior review and written approval, such review to be reasonable and in
accordance with RIM's internal co-branding guidelines, BSP may co-brand the
Products and Services and use co-branded packaging, documentation, and other
co-branded materials in connection with its activities hereunder, RIM and BSP
shall negotiate in good faith regarding any additional terms and conditions that
would apply to BSP's co-branding activities.

3.13   Tier I Reports. When requested by RIM, but not more often than quarterly,
BSP shall provide to RIM, in writing, a summary report of Tier I incidents
related to Product, Service or installation issues to facilitate RIM's quality
control and product planning. RIM reserves the right, at RIM's expense, to audit
BSP's Tier I Support, including without limitation, the Tier I process, quality
and customer satisfaction.

is essential to minimize product deterioration. Accordingly, BSP agrees to abide
by RIM's reasonable policies and guidelines with respect to inventory
management, including such guidelines as are applicable to replacing the
alkaline battery of any product in the BSP's inventory prior to the total
discharge of such battery. The BSP agrees to work with RIM to implement an
inventory management program in accordance with such guidelines. RIM shall be
excused from its warranty obligations with respect to any Product defect
resulting solely from BSP's failure to manage its inventory in accordance with
such guidelines.

3.15  RMA Policy. BSP agrees and acknowledges it is aware of and will follow the
RIM RMA Policy, included in Schedule C, relative to Product to be returned under
RIM's limited warranty or for Product to be returned outside of RIM's limited
warranty.

schedule.

excess amount was paid until repaid to BSP.

6.    RECORDS

with activity under this Agreement. RIM may audit the relevant books and/or
records that relate to Tier I Support and/or the amounts paid to BSP by RIM

give notice to BSP of such non-compliance, and BSP shall cure such
non-compliance within thirty (30) days of receipt of such notice (the "Cure
Period'). Should BSP fail to cute such non-compliance within the Cure Period to
the satisfaction of RIM, RIM may terminate this Agreement immediately without
further notice and/or, at RIM's option, may discontinue any co-operative or
marketing development program. Notwithstanding the foregoing, RIM may terminate
this Agreement immediately upon further non-compliance if there are two (2)
events of non-compliance within any twelve month period. Should any audit reveal
that co-operative or marketing development funds were not used for RIM approved
marketing activities, the BSP shall immediately refund to RIM such co-operative
or marketing development funds.

6.02  Notice of Claim; Notice of Change of Control. The BSP will notify RIM
promptly in writing of (a) any claim or proceeding involving the Products and

without cause upon one hundred and twenty (120) days prior written notice to the
other Party, provided, however, that such notice shall not be given by either

Fees due to RIM by BSP which may extend and/or accrue beyond the Term of this
Agreement, including, but not limited to, Fees due to RIM by the BSP for
continued provision of Service beyond the Term of this Agreement, or any renewal
thereof, shall survive termination of this Agreement for any reason. In
addition, should BSP terminate for convenience, any scheduled delivery pursuant

termination and the BSP shall be responsible for the payment of such Fees within
thirty (30) days of receipt of the invoice for the ordered Products.

7.03  Termination for Cause. Either Party may terminate this Agreement in the
event of the default of the other Party in the performance of any of the terms
and conditions of this Agreement or any present or future Schedule hereto if
such Party fails to correct the breach within the thirty (30) day period
following delivery of written notice to the other Party of such default. In
addition, RIM may terminate this Agreement for cause without a cure period and
without prior notice (a) should an audit reveal that co-operative marketing fees
were not used for approved marketing activities and/or (b) any misrepresentation
pursuant to this Agreement of RIM, or RIM's Product(s) and Service(s) or (c) in
the event that BSP fails to make timely payment for three months in any twelve
month period such that the payments are delayed by a cumulative total of twenty
(20) days. Either Party may immediately terminate this Agreement if the other
Party institutes or if any proceeding is commenced against or affecting the
other Party: (i) seeking to adjudicate it a bankrupt or insolvent; (ii) seeking
liquidation, dissolution, winding up, reorganization, arrangement, protection,
relief or composition of it or any of its property or debt; (iii) making a
proposal with respect to it under any law relating to bankruptcy, insolvency,
reorganization or compromise of debts or other similar laws; or (iv) seeking to

Party's rights of termination in this Agreement are reasonable in the
circumstances and have been freely bargained by the Parties. The BSP
acknowledges and agrees that any goodwill created in the Territory by the BSP
with respect to the Product(s) and Service(s) and RIM or in any way related
thereto is the sole property of RIM and the BSP has no right therein and any
interest that the BSP has therein is hereby transferred to RIM, and that the BSP
has been adequately compensated therefor.

7.04  Force Majeure. Neither Party shall be liable to the other for failure or
delay in the performance of a required obligation if such failure or delay is
caused by strike, riot, fire, flood, natural disaster, or other similar cause
beyond such Party's control, provided that such Party gives prompt written
notice of such condition and resumes its performance as soon as possible, and
provided further that the other Party may terminate this Agreement if such
condition continues for a period of one hundred eighty (180) days. There shall
be no Force Majeure event that will excuse performance by either Party for the
payment of any commissions, fees or set-offs under this Agreement.

7.05  Effect of Termination. Upon expiration or termination of this Agreement
the BSP rights granted pursuant to this Agreement shall cease except the BSP
rights granted pursuant to Section 2.01 shall continue until such time as the
BSP has depleted the BSP inventory or [**] from the last date Product is
delivered to the BSP pursuant to an order accepted by RIM and not yet fulfilled,
whichever occurs first. In addition, the BSP shall return to RIM any and all
marketing materials supplied to BSP by RIM in support of this Agreement and, if
applicable, shall certify in writing that all archival or backup copies of the
applicable BlackBerry Software has been deleted from any computer system and
destroyed. Service for any Product delivered on or before the expiration of the
Term, for which Service has been activated, shall be continued through the end

to RIM any outstanding Fees due to RIM and any subsequent Fees due for Services
and/or Products scheduled to be provided or delivered, as applicable, as such
become due, upon receipt of an invoice from RIM. The termination of this
Agreement shall not limit either Party from pursuing any other remedies
available to it, including injunctive relief, nor shall such termination relieve
the BSP obligation to pay monthly Service fees pursuant to this Agreement until

RIM that the BSP has agreed to pay under any Initial Order and/or BSP Purchase
Order or other similar ordering document under this Agreement. The Parties'

8.    INDEMNITY, WARRANTIES, REMEDIES, LIMITATION OF LIABILITY

8.01  Indemnity of BSP. Subject to the limitation of liability set forth in
Section 8.03, RIM will defend and indemnify the BSP, its successors and assigns
with respect to amounts required to be paid to a third party from a claim that
the Products furnished and used within the scope of this Agreement infringe(s)
such third party's United States or Canadian copyright or patent, provided that:
(a) the BSP notifies RIM in writing promptly of the claim; (b) RIM has sole
control of the defense and all related settlement negotiations and RIM has,
without limitation, the sole, unfettered discretion to compromise and settle
such claim; and (c) the BSP provides RIM with the assistance, information and
authority necessary to perform RIM's obligations under this paragraph.
Reasonable out-of-pocket expenses incurred by the BSP in providing such
assistance will be reimbursed by RIM. In the event that the use of the Products
or Services is likely to be enjoined, RIM shall either (i) modify the Products
or Services to make them non-infringing (ii) replace the Products or Services
with non-infringing goods and services of comparable functionality and value or
(iii) obtain, at no cost to BSP, the right for BSP and its end users to continue
to use the Products or Services. If RIM determines, in its sole discretion that
performance of (i), (ii) or (iii) herein is not commercially feasible with
respect to Products, then RIM shall accept the return of such Products, and
shall refund to the BSP the amount paid for such Products, discounted using a
straight-line method over a period of five years. If RIM determines, in its sole
discretion that performance of (i), (ii) or (iii) herein is not commercially
feasible with respect to Services, the RIM shall refund to the BSP an amount
equal to the fees paid for one (1) month of service.

RIM shall have no liability for any claim of infringement based on: (a) use of a
superseded or altered release or version of any Product if the infringement
would have been avoided by the use of a current unaltered release or version of
such Product that RIM has, as of the time the claim of infringement arose, made
commercially available to the BSP or to the installed End-User base; (b) the
combination, operation or use of any Product and/or Service furnished under this
Agreement with software, hardware, service or other material not furnished by
RIM if such infringement would have been avoided by the use of such Product
and/or Service without such software, hardware, service or other material; or
(c) breach by BSP of a material provision of this Agreement with respect to the
trademarks of a third party licensed to BSP by RIM.

RIM shall defend, indemnify, and hold harmless BSP (including its officers,
director, employees, successors, and Affiliates) from any third party claims,
damages, liabilities, losses, or expenses (including without limitation
reasonable attorney fees and costs) incurred by BSP in connection with any
representation, warranties, guarantee or other statements made hereunder
regarding the Products and Services which are consistent with those made with
this Agreement, the applicable Software License Agreement, the User's Manual,
the RIM approved BSP Order Form, the BSP End-User Agreement or otherwise by
reference to RIM's web site(s) or otherwise provided in writing by RIM.

8.02  Warranties. RIM warrants to the BSP that for a period that begins upon
receipt by the BSP of any Product under this Agreement and concluding the
earlier of [**] months from date the Product is delivered to the BSP or [**]
months from when the Product is first delivered to an End-User (the "Warranty
Period"), that any Product purchased hereunder will be free from all defects in
material and workmanship. The BSP shall be solely responsible for providing any
and all End-user Warranties for sales by the BSP. The Parties agree that with
respect to any Product sold to an End-User by the BSP, the BSP shall provide
such End-User with a limited warranty ("Limited Warranty") supported by RIM that
provides, among other items, for a warranty period not to exceed the Warranty
Period or one (1) year, from the date the Product is first received by the
End-User, whichever occurs first. RIM's Limited Warranty is included in Schedule
C. Should there be a conflict between this Section 8.02 and RIM's Limited
Warranty, this Section 8.02 shall prevail. The BSP shall not represent that RIM
is responsible to the End-User for any warranty that is not explicitly provided
for under the Limited Warranty. The failure to maintain an adequate inventory
management program that includes a process for replacing alkaline batteries in
Product in inventory will be considered abuse, and any product damaged as a
result of such abuse will not be covered under the Limited Warranty. After the
expiration of the Warranty Period, for as long as an End-user continues to
obtain the Service from RIM, such End-User shall be entitled to receive any bug
fix, upgrade or enhancement made generally available to other customers of the
BlackBerry Internet Edition Software at such price, if any, charged to such
other customers.

8.03  Limitation of Liability. IN NO EVENT, INCLUDING, WITHOUT LIMITATION,
TERMINATION OF THIS AGREEMENT, SHALL EITHER PARTY BE LIABLE FOR ANY INDIRECT,
INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES, OR DAMAGES FOR LOSS OF PROFITS,
REVENUE, DATA OR USE, INCURRED BY THE OTHER PARTYOR ANY THIRD PARTY, WHETHER IN
AN ACTION IN CONTRACT OR TORT, EVEN IF THE OTHER PARTY OR ANY OTHER PERSON HAS
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. RIM'S LIABILITY FOR DAMAGES
HEREUNDER SHALL IN NO EVENT EXCEED THE AMOUNT PAID TO THE RIM UNDER THIS
AGREEMENT. THE FOREGOING LIMITATION ON RECOVERY SHALL NOT BE CONSTRUED AS
PRECLUDING RIM FROM RECOVERING ITS PROFIT IN ANY ACTION FOR PAYMENT UNDER THIS
AGREEMENT.

The provisions of this Article 8 allocate the risks under this Agreement between
RIM and the BSP. RIM's pricing of Products and Services reflects this allocation
of risk and the limitation of liability specified herein.

8.04  Indemnification of RIM. The BSP agrees to inform RIM of any known breach
by any End-User of the terms of the BlackBerry Software License Agreement and
the terms of any applicable End-User Agreement and/or BSP Order Form. Except as
indicated in Section 8.01, the BSP will defend, and indemnify and hold RIM
harmless against all damages to RIM caused by the BSP failure to comply with the
terms of this Agreement.

The BSP shall defend, indemnify, and hold harmless RIM, RIM's suppliers,
successors, affiliates, agents and assigns from any claims, damages, losses, or
expenses (including without limitation attorney fees and costs) incurred by RIM,
RIM's suppliers in connection with all claims, suits, judgements and causes of
action (i) for infringement of patents or other proprietary rights arising from
combining with or using any device, system or service in connection with the
Product or Services and the BSP service or any portion thereof (ii) for libel,
slander, defamation or infringement of copyright or other proprietary right with
respect to material transmitted by the BSP or the BSP's End-User using the
BlackBerry Product or (iii) injury, death or property damage arising in
connection with the use or non-use of the Product and/or Services in a manner
that is inconsistent with the proper use of the Product and/or Services as set
forth in Documentation. No remedy herein conferred upon RIM is intended to be,
nor shall it be construed to be, exclusive of any other remedy provided herein
or as allowed by law or in equity, but all such remedies shall be cumulative. In
the event of the termination of this Agreement pursuant to this Section 8.04,
the BSP shall pay to RIM all attorney fees, collection fees, and related
expenses, expended or incurred by RIM in the enforcement of any right or
privilege hereunder (including, but not limited to, telephone, freight, express
and postal charges, expenses of paid investigators and reasonable compensation
for time of RIM's representatives).

8.05  Product End of Life. RIM shall provide the BSP with [**] prior written
notice of any termination of manufacture of the Product ("End-Of-Life"). In the
event this Agreement terminates or expires prior to RIM's issuance of an
End-Of-Life notice, the notice will be deemed to be issued as of such expiration
or termination, unless such termination is by RIM for cause or by the BSP for
any reason. Any Initial Order accepted by RIM with deliveries extending beyond
the End-Of-Life date will be fulfilled without interruption. RIM will provide
repair service for up to [**] following any End-Of-Life for the Product or in
accordance with the Warranty Period, whichever occurs last.

8.06  Equitable Relief. The BSP acknowledges that any breach of its obligations
with respect to proprietary rights of RIM shall cause RIM irreparable injury far
which there are inadequate remedies at law, and that, at the discretion of the
court under the usual principles of equity, RIM shall be entitled to equitable
relief in addition to all other remedies available to it.

9.    GENERAL TERMS AND CONDITIONS

9.01  User Data. Except for communications of an emergency nature as may be
required by law or by the airtime service carrier in order to comply with FCC or
other governmental regulations, during the Term of this Agreement, BSP must

End-Users initiated by RIM. RIM may only disclose the User Data as follows: (i)

9.02  Nondisclosure. Each party agrees that the Confidential information of the
other Party will be held in confidence to the same extent and the same manner as
each Party protects its own Confidential Information, but each Party agrees that
in no event will less than reasonable care be used. Each Party shall, however,
be permitted to disclose relevant aspects of such Confidential Information to
its officers or employees on a need-to-know basis, provided that they shall be
bound to protect the Confidential Information to the same extent as required
under this Agreement. Each Party agrees to use such Confidential Information
only for purposes of this Agreement. The obligations set forth in this Section
9.01 do not apply if and to the extent the Party receiving Confidential
Information ("Receiving Party") establishes that: (i) the information disclosed
to the Receiving Party was already known to the Receiving Party, without
obligation to keep it confidential; (ii) the Receiving Party received the
information in good faith from a third party lawfully in possession thereof
without obligation to keep such information confidential; (iii) the information
was publicly known at the time of its receipt by the Receiving Party or has
become publicly known other than by a breach of this Agreement; (iv) the
information is independently developed by the Receiving Party without use of the
other party's Confidential Information; or (v) the information is required to be
disclosed by applicable statute or regulation or by judicial or administrative
process; provided that, in the case of (v), the Receiving Patty will use
reasonable efforts under the circumstances to notify the other party of such
requirements so as to provide such party the opportunity to obtain such
protective orders or other relief as the compelling court or other entity may
grant. As used herein, "Confidential Information" means, except as otherwise
specifically provided in the Agreement, each party's (i) trade secrets under
applicable law (including, without limitation, financial information, processes,
formulas, specifications, programs, instructions, technical know-how, methods
and procedures for operation, and benchmark test results); (ii) any confidential
or other proprietary information, whether of a technical, business or other
nature that is of value to the owner of such information and is treated as
confidential (including, without limitation, User Data, information about
employees, customers, marketing strategies, services, business or technical
plans and proposals, in any form); (iii) any other information identified by a
party as "Confidential Information"; (iv) any other information relating to
party that is or should be reasonably understood to be confidential or
proprietary; (v) the terms of this Agreement or any information relating thereto
(except as required by applicable law), and (vi) information on RIM's secure,

9.03  Copyrights. All copyrights in the BlackBerry Software components, the
User's Manual and all associated BlackBerry Product and Service Documentation
and associated marketing literature are owned by RIM and/or its suppliers and
the BSP shall not modify the copyright notices on or associated with the
Products and Services.

9.04  Trademarks. RIM, the RIM Logo, BlackBerry, BlackBerry Internet Edition,
the BlackBerry Logo and any other trademarks and service marks adopted by RIM
from time to time to identify the Products, Services or other RIM product or
service belong to RIM. The BSP shall have no rights in such marks except as
expressly set forth herein and as specified in writing from time to time. The
BSP's use of RIM's trademarks, or any other trademarks or service marks that RIM
is permitted to use in conjunction with the offering of its Product(s) and
Service(s) including, without limitation, the authorized use of the trademarks
and service marks of Cantel AT&T or BellSouth, as applicable, and its
subsidiaries, or any other third patty whose trademark or service mark appears
in conjunction with RIM's offering of the Product(s) and Service(s) shall be
under RIM's trademark policies and procedures in effect from time-to-time and
any trademark usage manual provided to the BSP directly or through RIM's
website(s).

Prior to publishing or disseminating any advertisement, press release or
promotional materials bearing one or more trademarks of RIM, the BSP agrees to
deliver a sample of the advertisement, press release or promotional materials to
RIM for prior approval, and such approval shall not be unreasonably withheld. If
RIM notifies the BSP that the use of the trademark of RIM is inappropriate, the
BSP will not publish or otherwise disseminate the advertisement, press release
or promotional materials until they have been modified to RIM's satisfaction.

The BSP shall not market the Products in any way that implies that the Products
are the proprietary product of the BSP or of any party other than RIM. The BSP
shall not remove, alter, deface, or otherwise impair the recognition of any
trademark of RIM or RIM's suppliers, including, but not limited to, any marks or
brands on any Products, label, documentation or packaging, or in marketing
materials. RIM shall not have any liability to the BSP for any claims made by
third parties relating to the BSP's use of RIM's trademarks.

unless the BSP has prior written permission from Cantel AT&T or BellSouth, as
applicable.

Should BSP fail to comply with the provisions of this section 9.04 and/or with
RIM's Branding Guidelines as set out in Schedule E and as modified from time to
time, RIM shall notify BSP of such non-compliance and reserves the right to
immediately discontinue shipment of Products to BSP under this Agreement. Upon
receipt of such notice, BSP shall immediately and continuously act to cure such
non-compliance, such cure to be effected within a commercially reasonable
timeframe. Should BSP fail to cure such non-compliance, RIM may terminate this
Agreement for cause in accordance with section 7.03 herein. This remedy does not
preclude RIM from any other remedy which it may have in law or in equity,
including, but not limited to, injunctive relief.

9.05  Relationships between Parties. In all matters relating to this Agreement,
the BSP shall act as an independent contractor. Neither Party will represent
that it has any authority to assume or create any obligation, express or
implied, on behalf of the other Party, nor to represent the other Party as
agent, employee, franchisee, or in any other capacity.

9.06 Successors and Assigns. This Agreement shall inure to the benefit of and be
binding upon the Parties and their respective successors and assigns. Neither
Party may assign or otherwise transfer any rights under this Agreement without
the prior written consent of the other party, provided that either Party may
transfer and assign any rights hereunder without such consent to Affiliates or
successors in interest of such Party.

9.07  Notice. All notices, including notices of address change, required to be
sent hereunder shall be in writing and when sent in writing shall be deemed to
have been given when delivered by courier service or mailed by first class mail
to the applicable address listed at the beginning of this Agreement. To expedite
order processing, the BSP agrees that RIM may treat documents faxed by the BSP
to RIM as original documents; nevertheless, either Party may require the other
to exchange original signed documents.

9.08  Governing Law/Jurisdiction. This Agreement is deemed to be made under and
shall be interpreted in accordance with the laws of New York, excluding any
conflict of laws provisions.

The foregoing shall not limit either Party's right to obtain injunctive relief
through a court of competent jurisdiction in accordance with its rights under
this Agreement. This Agreement shall not be governed by the United Nations
Convention of Contracts for the International Sale of Goods, the application of
which is expressly excluded.

9.09  Government Rights. The Products and Services have been developed at
private expense. Any marketing, selling, renting, leasing, licensing or
distribution of any Products or Services to any Canadian or U.S. Federal, state,
province or local government entity shall be specifically limited to the
End-User Agreement and the applicable BlackBerry Product specifications. The
BlackBerry Software is provided with RESTRICTED RIGHTS. Use, duplication or
disclosure by the U.S. Government is subject to restrictions as set forth in
DFARS 227.7202 - 227-7204 or in FAR 52.227-19, as applicable. Contractor is
Research In Motion Limited, 295 Phillip Street, Waterloo, Ontario N2L 3W8.

9.10  Severability. In the event any provision of this Agreement is held by a
court of competent jurisdiction to be invalid or unenforceable, the remaining
provisions of this Agreement will remain in full force and effect.

9.11  Export. The BSP agrees to comply fully with all relevant export laws and
regulations of the United States and Canada to assure that neither the Products,
nor any direct product thereof, are exported, directly or indirectly, in
violation of United States and/or Canadian law. The BSP acknowledges that
certain versions of the BlackBerry Software operate with a level of data
encryption that, as of the Effective Date, may not be exported outside of the
United States and Canada without obtaining applicable permits, if at all.
Accordingly, without limiting the generality of this Section 9.11, the BSP
agrees that it shall not export, nor encourage or induce any party, customer or
potential customer, to export such BlackBerry Product from the geographic region
comprising the United States and Canada.

9.12 Waiver. The waiver by either Party of any default or breach of this
Agreement shall not constitute a waiver of any other or subsequent default or
breach.

9.13 Entire Agreement. This Agreement RIM's Standard Terms and Conditions of
Sale, and any attached Schedules, addenda and/or Exhibits, constitutes the
complete agreement between the Parties and supersedes all prior or
contemporaneous agreements or representations, written or oral, concerning the
subject matter of this Agreement. This Agreement may not be modified or amended
except in writing signed by a duly-authorized representative of each Party; no
other act, document, usage or custom shall be deemed to amend or modify this
Agreement. This Agreement may be executed in any number of counterparts, each of
which shall be an original and all of which shall constitute together but one of
the same document.

Services, subject to RIM's standard advertising and trademark usage policies and
guides and, in any case, only with the prior written approval of RIM, except as

agree to issue a press release as relates to this Agreement. The intent embodied
in the mutual press release is to define for the market the nature of the
relationship between the Parties and to describe Parties' commitment to work
together to co-market existing and future wireless portal solutions.

9.15 Conditional Obligations. Notwithstanding any other provision in this
Agreement, BSP acknowledges and agrees that this Agreement is conditioned upon
RIM obtaining any approvals as may be necessary from BellSouth Wireless Data to
enable RIM to offer to BSP the airtime services contemplated hereunder. If RIM
is unable to secure such approvals as may be required within [**] days from the
Effective Date, this Agreement may be terminated by BSP, and in any event,
notwithstanding any other provision of this Agreement, RIM shall have no
obligation to provide airtime services. If the Parties agree to proceed with the
Agreement, BSP agrees to pay an access fee of [**] per month per End-User and
shall use its own airtime arrangements with BellSouth Wireless Data if RIM is
precluded from providing to BSP airtime services.

representatives signing below, execute and agree to be bound by the terms and
conditions contained in this Agreement.

to approval and acceptance by an authorized employee of RIM. If you do not agree
to be legally bound by these provisions, including, without limitation, the
terms stated on the Order Form, You should not sign the Order Form. If You do

(collectively, "the Chares"). All applicable excise, value added, utility, sales

the date of termination of this Agreement in good working order and condition,
free from damage (physical or otherwise) and with all necessary components, You

         performance hereof by either or both Parties shall so survive the
         completion of performance, cancellation or termination of this
         Agreement.

(e)      Governing Law. The Agreement shall be construed in the United States in
         accordance with the laws of the State of Texas applicable to Agreements
         executed and wholly performed within that State without giving effect
         to any body of law governing conflicts of laws. This Agreement shall
         not be governed by the United Nations Convention of Contracts for the
         International Sale of Goods, the application of which is expressly
         excluded.

(f)      Severability. If a provision of this Agreement shall be invalid or
         unenforceable, such invalidity or unenforceability shall not invalidate
         or render unenforceable the entire Agreement, but rather (unless a
         failure of consideration would result therefrom) the entire Agreement
         shall be construed as if not containing the particular invalid or
         unenforceable provision or provisions, and the rights and obligations
         of each Party shall be construed and enforced accordingly.

disclosing party shall give notice to the other Party adequate to permit its
legal intervention.

7.    LIMITED PRODUCT WARRANTY. RIM warrants to the Buyer that the Products
shall substantially conform to RIM's specifications for a period of one (1) YEAR
from the date of original purchase (the "Warranty Period"). As RIM's sole
obligation and Buyer's exclusive remedy for any breach of warranty, RIM agrees,
at its sole option, to (i) use reasonable efforts to repair the Product with new
or refurbished replacement parts; (ii) replace the Product with a new or
refurbished unit, or (iii) refund the purchase price, provided Buyer returns the
defective Product to RIM with proof of purchase and RIM's authorization.

RIM's warranty hereunder does not apply in case of any damage caused by
accident, abuse, misuse, misapplication, or alteration of any kind (including
upgrades and expansions) performed by anyone other than RIM. The Products are
not designed or licensed for use in mission-critical application or in hazardous
environments requiring fail-safe controls, including without limitation

surface of any Product display, or to any data stored in the Product. In case of
return for repair or replacement, RIM shall have no obligation with respect to
any data stored in the Product. Except as provided in RIM's Software License,
RIM's warranty does not apply to RIM Software. EXCEPT AS EXPRESSLY PROVIDED IN

8.    LIABILITY. IN NO EVENT SHALL RIM BE LIABLE TO BUYER FOR, AND BUYER HEREBY

TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, WHETHER OR NOT SUCH DAMAGES WERE
FORESEEN OR THEIR LIKELIHOOD DISCLOSED, RIM SHALL NOT BE LIABLE TO BUYER OR ANY
THIRD PARTY CLAIMING THROUGH BUYER, FOR ANY DAMAGES OF ANY KIND IN EXCESS OF THE
AMOUNTS PAID BY BUYER UNDER THE TERMS OF THIS AGREEMENT WITH RESPECT TO THE
PRODUCTS GIVING RISE TO SUCH DAMAGES. SOME JURISDICTIONS DO NOT ALLOW THE
EXCLUSION OF OR LIMITATION ON IMPLIED CONDITIONS, WARRANTIES, OR DAMAGES, SO
SOME OR ALL OF THE FOREGOING MAY NOT APPLY TO YOU. The foregoing limitation
precluding recovery of lost profits shall not be construed so as to preclude RIM
from recovering its contract price in any action or cause on or under this
Agreement.

suppliers and is subject to copyright and other intellectual property laws.
Buyer's only rights with respect to any RIM Software included with the Products
shall be as provided under the terms of RIM's Software License. Title to all RIM
Software remains with RIM. Buyer agrees that RIM retains ownership of all right,
title and interest in all intellectual property, works of authorship, trade
secrets and the like in all aspects of the Products. Buyer and its affiliates
and sub-contractors agree not to reverse engineer any aspect of the Software
and/or Products supplied under this Agreement and further agree to pay assessed
damages should such action take place.

10.   MISCELLANEOUS PROVISIONS.

10.1  No Assignment. Neither Party may assign this Agreement without the other
Party's prior written consent, which consent will not be unreasonably withheld;
provided, consent to any assignment which would not materially affect the rights
and obligations of either Party, including without limitation the ability to
perform hereunder, will not be withheld. RIM may assign this Agreement without
consent to any purchaser of a majority of RIM's outstanding shares or to any
purchaser of substantially all of the assets of RIM that relate to this
transaction.

10.2  Notices. Notice hereunder will be in writing, to the attention of both the
Chief Executive Officer and the legal department of the recipient at its address
below or such other address as the recipient may have properly noticed, and is
effective upon delivery to the recipient by express courier or certified mail.

10.3  Governance. This Agreement is governed by, and construed, interpreted and
enforced in accordance with the internal substantive laws of Texas if the Buyer
is in the U.S. or otherwise in accordance with the internal substantive laws of
the Province of Ontario. In so construing, interpreting and enforcing this
Agreement, choice of law principles shall not apply. The United Nations
Convention on Contracts for the International Sale of Goods is inapplicable, and
the Parties express disclaim its applicability. The prevailing Party in any
action hereupon will be entitled to recover, in addition to any other award,
reasonable related costs, expenses, and legal costs and fees (which legal costs
and fees, if an action is brought in Canada, shall be on a solicitor/client
basis). Buyer acknowledges and agrees that any Software under this Agreement was
developed at private expense. If acquired under an agreement with the U.S.
Government or any contractor thereto, it is acquired as "commercial computer
software" subject to the provisions hereof, as specified in 48 CFR 12.212 of the
FAR and its successors, or if acquired for Department of Defense units, as
specified in 48 CFR 227-7202-2 of the DoD FAR Supplement and its successors.

10.4  Injunctive Relief. The Parties agree a material breach of the Agreement
may cause irreparable harm to either Party, for which a remedy at law may be
inadequate. Accordingly, in addition to any remedies at law, either Party may
seek injunctive relief without posting any security.

10.5  Independent Contractors. Nothing in this Agreement will be deemed to
create a joint venture, partnership, or agency relationship between the Parties
or empower one Party to assume or create any obligation on behalf of the other.

10.6  Export. Buyer hereby assures it will not export or re-export the Software
in violation of any applicable laws, regulations, or governmental orders,
including Canadian or U.S. versions of the same as applicable.

10.7  Force Majeure. Neither party is liable for failure or delay in performance
hereunder which is proximately caused by strikes, shortages, failure of
suppliers, riots, insurrection, fires, floods, storms, earthquakes, acts of God,
war, governmental action, labor conditions, or other cause beyond its reasonable
control. The failure to make any payment required under this Agreement shall
never be excused under this force majeure provision.

10.8  Credit Information. As a courtesy to Buyer, RIM may, in its sole
discretion, extend credit to Buyer subject to receipt of financial information
as may be requested by RIM. Buyer acknowledges and agrees that RIM has no
obligation to provide credit to Buyer, and the provision of credit shall in no
way modify the terms of this Agreement.

10.9 Entire Agreement. This Agreement is the entire agreement of the Parties on
the subjects hereof. Any portion hereof deemed or becoming unenforceable or
illegal is eliminated, the balance hereof remaining effective. No waiver of
breach or excuse of performance hereof is effective unless upon notice; however,
neither will constitute any further waiver or excuse.

10.10 Survival. The provisions of this Agreement that under a commercially
reasonable interpretation reveals that the Parties likely would have such
provisions survive termination or expiration of this Agreement shall survive to
the extent necessary to fulfill the purpose of such provision.

                           Research in Motion Limited
                              Return & Repair Guide

                             Policies and Procedures

Returning Goods for Repair

In order to return any goods for repair, the customer is required to contact
Research In Motion Limited ("RIM") and request a Return Material Authorization
("RMA") form and number. RIM may be contacted via phone or email as follows:

                          Phone: (519) 888-7465 x 3371
                              Email: repair@rim.net

Accompanying the request for a RMA form, the customer must provide to RIM the
customer name, phone number, fax number, the ship to address, the bill to
address, the quantity of goods being returned, the model number, the serial
number (MSN/,ESN or MAN/LLI number) and a description of the problem. Except for
the 850 or 950, and 962 units, the serial number is located on the label on the
outside of the unit. In order to view the serial number for the 850,950, and 962
units, the customer will need to open the battery compartment and remove the
battery. RIM will complete the RMA form based on the information provided by the
customer. RIM will assign an RMA number and fax the RMA form to the customer. If
the custom does not have a fax number, RIM will mail the form to the customer.
The customer should review the completed RMA form and make any corrections or
additions as may be necessary. RIM cannot guarantee that any personal data on
your product will not be lost.

The goods should be picked carefully and in a manner suitable to prevent any
physical and/or electrostatic damages. In order to prevent any electrostatic
damage, RIM recommends returned goods are packed in the original packaging.
Unless requested to do so by RIM, the customer should return only the item
needing repair and should not return any cables, batteries, adapters, etc. A
copy of the RMA form should be included within the return package. If more than
one package is being returned, at least one RMA form will need to be included.
RIM highly recommends that with multiple return packages, a copy of the RMA form
is included with each package. The assigned RMA number should be clearly marked
on each return package. If the goods are being returned from outside of Canada
and in order to ensure any duties or taxes are not charged on Canadian goods
being returned to Canada, three (3) copies of the RMA form should also be
attached to the outside of the package(s). Return packages must be shipped
prepaid. The RMA form will be Used by the customer as the commercial invoice.

Goods for repairs must be shipped prepaid to

                               Research In Motion

misapplication, immersion, contamination, fire, flood, lightning, or other
similar actions, the goods will not be covered by any warranty and the policy
for repair and/or refurbishment shall be as indicated under "Goods Not Under
Warranty" below.

third party software used either internally or externally to the goods or that
modifications were made to the operation or physical appearance of the goods,

published pricing. The customer may choose to a) have the goods repaired; b)
decline to have the goods repaired and request the goods be returned; or c)
decline to have the goods repaired or returned.

Should the customer choose to have the goods repaired and/or refurbished, the
customer will be required to provide a purchase order to RIM for such repair.
Upon receipt of the purchase order, RIM will repair, refurbish the goods and
return the goods, at the customer `s expense, to the customer. Goods returned no
longer under warranty will be granted a ninety (90) day warranty from the date

device. Should RIM determine the device to be non warranty as outlined in the

invoiced the applicable repair charge or charges as listed in the then current
published price list. If RIM determines the device to be non-repairable the full
list price of the replacement device shall be invoiced.

Inspection/Analysis

Should it be determined by RIM that the returned goods are functioning correctly
and there is "no failure", RIM will notify the customer, return the goods to the
customer "freight collect" and invoice the customer for the inspection and
evaluation of the goods subject to RIM's then current inspection fee, whether or
not the goods are under warranty.

                                      -30-

                                  Schedule C-4

                                Limited Warranty

Research In Motion Limited ("RIM"), the manufacturer and provider of the
BlackBerry(TM) Solution, comprising the BlackBerry Handheld, which together with
the BlackBerry Cradle and Holster comprise the BlackBerry Hardware, the
BlackBerry Desktop Software and the associated wireless data service and
documentation, warrants to YOU, the end-user ("YOU") that the BlackBerry
Hardware will be free from defects in workmanship and materials for a period
that is the shorter of (i) one (1) year from the date that the BlackBerry
Hardware was first purchased by YOU as an original end-user and (ii) the period
ending upon your breach of the End-User's Agreement entered into when YOU
ordered the BlackBerry Solution (the "Purchase Warranty Period"). If YOU obtain
the BlackBerry Hardware through a rental or lease program, or any other
non-purchase program, the warranty period (the "Rental Warranty Period") shall
be for as long as YOU continue to pay any required rental or lease fees. In no
event, however, shall the Rental Warranty Period exceed three (3) years.
Continued repair or replacement after the expiration of a Rental Warranty Period
shall be at the sole discretion of RIM, and the continuance of a program of
repair and replacement after the expiration of the Rental Warranty Period shall
net constitute a waiver of RIM's right to terminate this Limited Warranty or to
declare that the Limited Warranty is no longer in effect. The Purchase Warranty
Period and the Rental Warranty Period shall be hereinafter referred to as the
"Applicable Warranty Period" meaning one or the other of the Purchase Warranty
Period or the Rental Warranty Period, as the context may require. This Limited
Warranty is not transferable. During the Applicable Warranty Period, the
BlackBerry Hardware, or one or more of the BlackBerry Hardware components, will
be repaired or replaced at RIM's option, without charge for either parts or
labour. If the BlackBerry Hardware (or component thereof) is repaired or
replaced during the Applicable Warranty Period, the Applicable Warranty Period
will expire, if a Purchase Warranty Period, upon the later of the 91st day after
repair or replacement or one year from the date of original purchase. If the
Applicable Warranty Period is a Rental Warranty Period, the Applicable Warranty
Period will expire upon the earlier of YOU failing to pay any applicable charge
or fee or three (3) years from the date the BlackBerry Hardware was first put
into service. Please consult your Blackberry Handheld User's Guide for
instructions on how to obtain customer support for your BlackBerry Hardware.

This Limited Warranty does not apply to normal wear and tear, and does not cover
repair or replacement of any BlackBerry Hardware damaged by misuse, accident,
abuse, neglect, misapplication, or defects due to repairs or modifications made
by anyone other than RIM or its authorized service representative. This Limited
Warranty does not cover physical damage to the surface of the BlackBerry
Hardware, including cracks or scratches on the LCD screen. This Limited Warranty
does not apply to any equipment other than the BlackBerry Hardware as defined in
this Limited Warranty, i.e., it does not apply to any alkaline battery provided
with your purchase, rental, lease or other means of acquiring the BlackBerry
Solution, or any damage caused by the leakage or any other malfunction of an
alkaline battery or any other accessory or peripheral equipment. This Limited
Warranty also does not apply if the malfunction results from the use of the
BlackBerry Hardware in conjunction with accessories, products, services or
ancillary or peripheral equipment not approved or provided by RIM, and where it
is determined by RIM that such malfunction is not the fault of the BlackBerry
Hardware itself. Additionally, if malfunction results from the failure of the
user to abide by the Safety Information contained in the package with the
BlackBerry Solution, the Limited Warranty may be void, and if it is not void, it
shall not apply. Data backup is presumed to be the responsibility of the user of
the BlackBerry Hardware. Neither your Wireless Solution Provider nor RIM is
responsible for data that may be damaged or lost at any time, including, without
limitation data lost or damaged during the servicing of the BlackBerry Hardware,
or through the use of synchronization software. In as much as the wireless data
service provided as part of the BlackBerry Solution is provided via RIM from a
third party provider, we cannot guarantee or warrant that the wireless data
service will always be available or will always function properly. For this and
other reasons, the BlackBerry Solution should not be relied upon for the
transmission of data relating to emergency or life-threatening or mission
critical situations, and RIM disclaiming any liability on its behalf and on
behalf of its Wireless Solution Providers for events or damages resulting from
such reliance or the failure of the wireless data service to perform or to be
available for your use of the BlackBerry Solution, including, without
limitation, the lack of service coverage in the area, in which YOU wish to use
the BlackBerry Solution. To the extent the third party providing the wireless
data service provides any warranties or guarantees that may be passed on to YOU,
such warranties and/or guarantees are automatically passed on to YOU without any

                                  Schedule D-1

                             BlackBerry Co-Op Funds

The objective of the BlackBerry Co-Op Program is to incent and reward BlackBerry
Wireless Solution Providers ("WSPs") by providing funds to those eligible WSPs,
by way of a reimbursement, to use for the purpose of subsidizing advertising,
direct mail campaigns and production or purchase of sales collateral ("Marketing
Initiatives") directed at the acquisition of new BlackBerry users. The extent of
the funds ("Co-Op Funds") provided by Research In Motion Limited ("RIM") to an
individual WSP is contingent upon the number of new BlackBerry users such WSP
acquired during the 1999 calendar year.

                            ELIGIBILITY REQUIREMENTS

o    Eligibility: To be eligible for Co-Op Reimbursement, the WSP must sell a
     minimum of [**] BlackBerry Handhelds(TM) ("Handhelds") in the preceding
     twelve (12) month period. To ensure all WSPs have an opportunity to
     participate, sales of BlackBerry Handhelds are considered on a rolling
     12-month basis, with the eligibility of a WSP being determined on a
     quarterly basis in the months of January, April, July and October. To
     maintain its eligibility to participate in the Co-Op program, a WSP must
     sell a minimum of [**] BlackBerry Handhelds in each preceding twelve (12)
     month period.

o    Co-Op Fund Calculation: Eligible WSPs are deemed to have accrued $[**] for
     each Handheld they sold during the previous twelve (12) month period, net
     of those Handhelds subsequently returned to RIM. Co-Op Funds deemed to have
     accrued to a WSP may be applied to one or more Marketing Initiatives.

o    Reimbursement: Eligible WSPs will be reimbursed by RIM, up to the amount
     accrued by the WSP pursuant to the Co-Op Fund calculation above, upon WSP:
     (i) providing RIM with satisfactory documentation that the Marketing
     Initiative undertaken by the WSP complied with RIM's Marketing Initiative
     guidelines set forth below; and (ii) providing RIM with satisfactory
     documentation of the cost incurred by the WSP for such Marketing
     Initiative.

o    Reimbursement Period/Forfeiture of Funds: In order to qualify for
     reimbursement, Marketing Initiatives must be completed on or before
     December 31, 2000. Co-Op Funds deemed to have accrued to a WSP in
     accordance with the Co-Op Fund calculation above but which are not applied
     to a Marketing Initiative undertaken during the 2000 calendar year will be
     automatically forfeited without notice to the WSP.

o    BlackBerry Logo Usage: WSP must adhere to the provisions contained in the
     "BlackBerry Branding Guide" with respect to the BlackBerry logo when using
     the Co-Op Funds in a Marketing Initiative.

                         MARKETING INITIATIVE GUIDELINES

o    Approved-Activities: Co-Op Funds may be used for any one or more of the
     following activities: print advertising, direct mailings and production or
     purchase of sales collateral, provided such activities adhere to the
     guidelines set forth below:

Print Advertising:

All print ads must (i) use the BlackBerry logo, which logo must be at least
[**]% of the size of the WSP's logo; and (ii) contain a photo of the BlackBerry
Handheld and have it clearly identified in writing as such.

Direct Mail:

Direct mail pieces must (i) use the BlackBerry logo, which logo must be at least

Handheld and have it clearly identified as such.

All sales collateral must use the BlackBerry logo, which logo must be at least
[**]% of the size of the WSP's logo.

                     APPLYING FOR REIMBURSEMENT/CO-OP FUNDS

o    Documentation Required:  In order to get reimbursed for a Marketing
     Initiative, WSPs must submit the following to RIM upon completion of the
     Marketing Initiative:

         (i)      Completed Joint Marketing Funds Reimbursement Form

         (ii)     Proof of Marketing Initiative which shall include:

                  a.   copy of the ad or direct mail piece;
                  b.   copies of all Invoices; and
                  c.   copies of the rate cards for publications involved or
                       data cards for mailing list used

o    Deadline for Reimbursement Requests: The completed Joint Marketing Funds
     Reimbursement Form and Proof of Performance must be remitted to RIM no
     later than [**] days after the conclusion of the Marketing Initiative.

                                     N2L 3W8

o    Approval of Reimbursement Requests: To be eligible for reimbursement, all
     Marketing Initiatives must follow the BlackBerry branding guidelines

                                  Schedule D-2

                       BlackBerry Market Development Funds

The objective of the Market Development Funds ("MDF") program is to reward and
assist those BlackBerry Wireless Solution Providers ("WSPs") who have performed
at an exceptional level in the previous twelve (12) months. Market Development
Funds are provided on a case-by-case basis, and RIM encourages BlackBerry
Wireless Solution Providers to work closely with RIM Channel Marketing to
develop the most effective strategies for using the funds.

                             ELGIBILITY REQUIREMENTS

o    Eligibility: WSPs who have sold [**] or more BlackBerry Handhelds in the
     preceding twelve (12) month period AND are committed to selling, at a
     minimum, [**] additional BlackBerry products in the next twelve (12) month
     period are eligible to participate in the MDF program. To ensure all WSPs
     have an opportunity to participate, sales of BlackBerry Handhelds are
     considered on a rolling 12-month basis, with the eligibility of a WSP being
     determined on a quarterly basis in the months of January, April, July and
     October. To maintain its eligibility to participate in the MDF program, a
     WSP must sell a minimum of [**] BlackBerry Handhelds in each preceding
     twelve (12) month period.

         Example 1: WSP sold [**] BlackBerrys in July 1999 but has not sold any
since that time.

         Example 2: WSP sold [**] BlackBerrys in July 1999 and [**] in December
1999.

         Example 3: WSP sold [**] BlackBerrys in July 1999, [**] in September
1999 and [**] in December 1999.

         Based on the above scenarios, each having sold at least [**]
         BlackBerrys, all three WSPs have become eligible to participate in the
         MDF program. Assuming the WSPs do not sell any other BlackBerry
         products: the WSP in example 1 will maintain its eligibility to
         participate in the MDF program until July 2000 (ie. 12 months from date
         of sale); the WSP in example 2 will maintain its eligibility to
         participate in the MDF program until July 2000 (ie. the [**]
         BlackBerrys sold in July 1999 are no longer counted in the number of
         BlackBerrys sold by the WSP after July 2000 and, accordingly, after
         July 2000, the WSP is only deemed to have sold 250 BlackBerrys--[**]
         below the required [**]); and the WSP in example 3 will maintain its
         eligibility to participate in the MDF program until December 2000 (ie.
         Although[**] BlackBerrys sales are no longer counted after July 2000
         and an additional [**] after September 2000, the WSP had sold the
         requisite [**] in December 1999 making this WSP eligible to participate
         for an additional twelve months from that date).

o    Funding: MDF is determined in accordance with projected sales contained in
     the written business plan developed and prepared jointly by the WSP and RIM
     for the upcoming twelve (12) month period. For each BlackBerry Handheld the
     WSP projects to sell in the upcoming twelve-month period, RIM shall
     contribute $[**] towards the WSPs MDF account. BLACKBERRY SALES MADE BY THE
     WSP IN THE PREVIOUS TWELVE-MONTH PERIOD ARE NOT USED IN THE MDF
     CALCULATION.

o    Participation in MDF Program: RIM will only review applications of the WSPs
     requesting to participate in the MDF program on a quarterly basis beginning
     in April, 2000.

o    Obligation of WSP: It is the sole responsibility of the WSP to determine
     whether it qualifies to participate in the MDF program or not and whether
     it chooses to apply for MDF. The MDF program is optional and RIM takes no
     responsibility in contacting a WSP to inform it that it has qualified to
     participate in the program.

                                   MDF PROGRAM

program and will provide support to the WSP in various ways including: (i)

(ii) providing ongoing assistance/advice, as is required by the WSP, to carry
out the business plan; (iii) providing the WSP with a variety of marketing
materials including product brochures, life-size product information cards, RIM
brochures, etc.;

o    Business Plan: To be entitled to MDF funds, the business plan developed and
     agreed to by the WSP and RIM must contain a commitment on the WSP's behalf
     to sell, over the upcoming twelve (12) month period, an additional [**]
     (net of returns and order cancellations) BlackBerrys.

o    Uses of MDF Funds:  Uses of MDF include, but are not limited to:

     (i)   Development of sales collateral
     (ii)  Point-of-Purchase displays;
     (iii) Promotional Events;
     (iv)  Market Awareness Activities; and
     (v)   Other promotional activities that accelerate the sale of BlackBerry

Funds: Once the WSP's written business plan has been approved by RIM and the WSP
has provided RIM with satisfactory evidence that steps have been taken to
implement the plan, RIM shall make note of the MDF funds available to the WSP
for BlackBerry marketing activities.

                             APPLYING FOR MDF FUNDS

Pre-Approval: RIM encourages BlackBerry Wireless Solution Providers to work with
RIM Channel Marketing on an ongoing basis to develop the most effective and

programs.

                        BlackBerry Logo Usage Guidelines

Maintaining the integrity and color standards BlackBerry logo is of vital
importance. Through adherence to the guidelines described, a cohesive visual
image will reinforce the BlackBerry name and industry presence. Electronic files
of the BlackBerry logo are available from RIM's Marketing Department.

                                  Logo Variants

1.    The BlackBerry Logo

2.    The BlackBerry Logo with" Email In Motion" tag line

                                 Logo Integrity

To maintain the logo's integrity, use an original electronic file. Never alter
the BlackBerry logo. The logo must be reproduced from an original electronic
file provided by RIM. When reproducing the logo, it must not be distorted in any
way. Please do not:

o     simulate the logo with the use of a typeface

o     transpose the colors within the logo

o     change the proportions within the logo

o     use a pattern within the logo

                                 The Safety Zone

The safety zone is empty space that must surround a logo. No other elements may
infringe upon this space. The safety zone is the amount of space that should
surround the BlackBerry logo to ensure legibility and easy recognition. No
written information or other company logos should appear within the specified
area. Acceptable clear space is equal to the height of the `B' in BlackBerry; it
adjusts proportionally according to the size of the logo you are using.

                                      Size

The RIM logo may be reduced or enlarged proportionally as necessary on print
materials. However the size of the original electronic files provided by RIM
should not altered in a scale greater than +50% of original size. To ensure
clarity and comprehension, the logo may only be reduced to a minimum size such
that the bottom and top widths are 1" when measured from the left edge of the
`B' to the right edge of the `Y'.

                              Color Specifications

Reproducing the BlackBerry Logo in Full Color and Four Color Process

When reproduced in color, the BlackBerry logo should only appear on a white or
light colored background.

Pantone Spot Color - The BlackBerry logo should be reproduced for print material
using the Pantone Spot 1815C (Burgundy) and 100% Black whenever possible.

Process Color - When it must be reproduced for print materials in four-color
process, use the CMYK color model and assign color values as follows:

            Burgundy

              C: 0
              M: 91
              Y: 100
              K: 40

              Always match the color against a Pantone 1815C spot color swatch.

            Black:

              Process Black

Reproducing the BlackBerry Logo in One Color

It is recommended that the full-color version be used whenever possible. If
using the full-color version is too expensive or inappropriate for the printing
method used, one of the official one-color versions may be used.

The BlackBerry logo can also appear in print as black on white and white on
black. When reproducing the logo in one color format, all logo elements must
appear as solid black or solid white. Note: as a general rule, if the logo must
appear on a bright or dark color, the one color solid white reproduction of the
logo should be used.

                      BlackBerry Enterprise Server Software

                               (Exchange Edition)

The BlackBerry Enterprise Server (BES) Software consolidates the operation of
individual BlackBerry Desktop email redirectors into a server that the IT
department can monitor and control. With the BES, users don't have to leave
their computers running and laptop users can be supported. IT Departments handle
the centralized administration and control of mobile email and users can
continue to configure email redirection options using the BlackBerry Desktop
Software on their PCs.

BES for Microsoft Exchange Functionality

Email Redirection

o     Monitors the user's Microsoft Exchange inbox for new mail

o     Applies user definable filters to new messages to determine if and how the
      message will be relayed to the user's BlackBerry handheld

o     Compresses and encrypts these new messages and delivers them to the
      BlackBerry handheld via the Internet

o     Receives, via the Internet, messages composed on the BlackBerry handheld,
      then decompresses and decrypts the messages and places them in the user's
      Outbox for the corporate Exchange server to deliver.

Management

o     Administration of the BES is accomplished through user-interface
      extensions to the Exchange Administrator.

o     The BES logs to the NT event log so administrators can perform
      server-level monitoring using the standard event log monitoring tools

o     Operating statistics can be monitored via SNMP

o     User level monitoring is also available through the Exchange Administrator

o     New users can be batch imported and existing user stats can be exported
      for analysis.

Transport

o    Protocol - Message receipt and delivery relies on RIM's BlackBerry Service.

o    Compression - RIM's proprietary compression algorithm was designed for
     wireless messaging to provide high performance in a small footprint. This
     algorithm outperforms the V42bis standard for all message sizes and
     achieves approximately 2-to-1 compression on most average length text
     messages. Compression requires a gateway provided by the network provider
     which implements RIM's proprietary compression algorithm.

ISP Email Integration Software Functionality

ISP Email Mirroring

o     Operates with ISP's existing email accounts

o     The BlackBerry ISP Application Software uses "Push" architecture -
      messages are relayed to the BlackBerry Handheld as they arrive at the
      user's ISP account.

o     Messages sent from the BlackBerry Handheld appear to originate from the
      ISP account.

o     Messages sent from the BlackBerry Handheld are also copied to the ISP
      email inbox so the user has a complete record of email transactions made
      using the BlackBerry Handheld.  (These messages are not sent again to the
      handheld).

Web Based Filtering Engine

o     The user can set any number of filtering rules using a password
      protected personal web page. Each filter consists of criteria
      identifying which messages to act on and an action to perform on these
      messages.

o     The engine can filter messages based on the following criteria: sender(s)
      how addressed (To, CC, BCC) subject keyword(s) message keyword(s)
      important (high, low, normal)

o     If a message is matched, the following actions are available:

      forward the message to the handheld (i.e. the user can set the default
      action to hold all messages and set filters to let certain ones through)

      hold the message (i.e. if the default is forward all messages, the user
      can set filters to hold certain messages back)

      forward the message with high priority -on the handheld, these
      messages are marked with an exclamation and the user can turn
      notification off for all but these priority messages.

Web Based ISP Administration Tools

o     A password protected web site provides the ISP with management tools
      for users of the BlackBerry ISP Solution.

o     Add, delete and edit ISP users

o     Modify ISP user information

o     The web site provides information on the status of the BlackBerry
      Service as well as the wireless network (for troubleshooting purposes).

o     The ISP Administration Web Site also provides access to help files and
      BlackBerry ISP Solution service and support information.
