Exhibit 10.2

VIROPRO INC.

GUARANTY AND SURETYSHIP AGREEMENT

(this "Guaranty")

1.

For value received, intending to be legally bound hereby, and in order to induce
Westward Expansion Co. (the “Company”) to provide bridge financing in a Term
Loan Agreement and enter into the other transactions connected therewith with
Viropro International Inc., a corporation organized and existing under the
federal laws of Canada (hereinafter the “Borrower”), and as consideration
therefor, Viropro Inc. (the “Parent”), a  corporation organized and existing
under the laws of the state of Nevada and the parent corporation of the Borrower
as of the date of Parent's execution of this Guaranty, effective as of October
11, 2007 (the “Effective Date”), absolutely, unconditionally and irrevocably
guarantees to the Company and becomes surety for the prompt, full and faithful
payment, performance, keeping, observance and fulfillment by the Borrower, of
all agreements, covenants, duties, obligations, debts, liabilities and
indemnities, now or hereafter owing or existing, (collectively, “Obligations”)
of Borrower under the Term Loan Agreement, the Convertible Note and the Deed of
Hypothec effective as of even date herewith as amended from time to time
(hereinafter the “Credit Documents”), and under any other agreement or document
entered into or delivered by Borrower or issued by the Company in connection
therewith or related thereto, each as amended or extended from time to time upon
mutual agreement of the parties thereto (collectively with the Credit Documents,
the “Covered Agreements”).  All references herein to the Covered Agreements
shall mean any and all of the Covered Agreements.

2.

Upon the occurrence of any Event of Default (as defined herein), at the election
of the Company, Parent shall immediately pay the Company an amount equal to: (i)
any and all interest, penalties, fees and expenses (specifically including, but
not limited to, reasonable attorneys' fees and expenses) which the Borrower may
now or at any time hereafter owe to the Company pursuant to the Credit Documents
plus (ii) the principal amount of any and all indebtedness, liabilities and
other obligations, whether primary, absolute, secondary, direct, indirect,
fixed, contingent, liquidated, unliquidated, secured or unsecured, matured or
unmatured, joint, several or joint and several, due or to become due and whether
arising by agreement, note, discount, acceptance, overdraft or otherwise, which
the Borrower may now or at any time hereafter owe to the Company pursuant to the
Credit Documents.  Parent’s payment of such amount shall not relieve it of its
continuing obligations under this Guaranty.

3.

The liability of Parent under this Guaranty shall be immediate and shall not be
contingent upon the exercise or enforcement by the Company of any remedies it
may have against Borrower or any other Parent, obligor, collateral or security.
 This is a guaranty of payment and not of collection.  The Company shall not be
required at any time, as a condition of Parent’s liability hereunder, to make
demand upon or resort to payment from Borrower or any other person, or any of
their properties or estates, or resort to any collateral or security or pursue
or exhaust any other rights or remedies whatsoever.  Parent’s obligations to
make payments to the Company hereunder shall arise immediately upon Borrower’s
failure or refusal to pay or perform when due any Obligation whether as a result
of the Borrower’s insolvency or otherwise (an “Event of Default”).  Payment
shall be made by Parent hereunder within three business days of its receipt of
notice of an Event of Default or of Enforcement Expenses (as defined herein)
from the Company.

4.

Parent shall pay and be liable to the Company for (i) all costs and expenses
(including fees of attorneys and expert witnesses and court costs) paid or
incurred by the

the Obligations and/or this Guaranty and (ii) interest on the unpaid amount due
hereunder accruing at an annual rate equal to twelve percent (12%)
(collectively, the “Enforcement Expenses”).

made in Unites States Dollars by wire transfer of immediately available funds in
accordance with the instructions provided by the Company to Parent.

Guaranty; and

(b)

upon the insolvency, bankruptcy or reorganization of either Borrower or Parent
or otherwise, all as though such rescinded, avoided or voided payment had not
been made, and notwithstanding any action or failure to act on the part of the
Company in reliance on such payment;

(c)

(d)

waiver, compromise or release of any of the Obligations or any of the Company’s
or any other person’s rights under the Covered Agreements; (iii) any acceptance,
exchange, release, discharge or non-perfection by the Company of any collateral
or security for or other guaranty or surety of the Obligations; (iv) any

release, discharge or defense of Parent from or to performance under this
Guaranty.

8.

If there is more than one Parent of the Obligations, all of the obligations and
agreements of Parent hereunder are joint and several with such other Parents.  

9.

Parent hereby waives: (a) promptness and diligence; (b) notice of the incurrence
of any of the Obligations or default by Borrower; (c) notice of any actions
taken by the Company or Borrower under the Covered Agreements; (d) acceptance of
this Guaranty and reliance hereon by the Company; (e) presentment, demand for
payment, notice of dishonor or nonpayment, protest and notice of protest with
respect to the Obligations or of the obligations of Parent hereunder or of any
other Parent, and all other notices and formalities to which Parent or Borrower
might be entitled, by statute or otherwise, the omission of or delay in which,
but for the provisions of this paragraph, might constitute grounds for relieving
Parent of its obligations hereunder; or (f) any right or claim of right to cause
a marshalling of any of the Borrower’s assets or to cause the Company to proceed
against any collateral or security before proceeding under this Guaranty against
Parent.  

10.

Parent will not exercise any rights which it may acquire by way of subrogation,
reimbursement, exoneration, participation, indemnification or contribution, by
reason of any payment made by it hereunder or otherwise, until after the date on
which all of the Obligations and all of the Enforcement Expenses shall have been
paid and satisfied in full; and until such time, any such rights against
Borrower shall be fully subordinated in lien and payment to any claim which the
Company now or hereafter may have against Borrower.  If any amount shall be paid
to Parent on account of such subrogation, reimbursement, exoneration,
participation, indemnification or contribution at any time when all of the
Obligations and all of the Enforcement Expenses shall not have been paid and
performed in full, such amount shall be held in trust for the benefit of the
Company, shall be segregated from other funds of Parent and shall forthwith be
paid over to the Company to be applied in whole or in part by the Company
against the Obligations and the Enforcement Expenses in such order as the
Company determines in its sole discretion.

11.

This Guaranty may not be assigned by Parent without the prior written consent of
the Company and any purported assignment without such consent shall be void and
unenforceable.

12.

The obligations of Parent hereunder shall not be subject to any counterclaim,
setoff, deduction or defense based upon any related or unrelated claim or
defense which Parent may now or hereafter have against Borrower or the Company,
or Borrower may now or hereafter have against the Company.

13.

This Guaranty may not be waived, amended, terminated, released or otherwise
changed except as expressly agreed in writing by Parent and the Company.  Any
waiver shall be

3

--------------------------------------------------------------------------------

effective only in the specific instance and for the specific purpose for which
given.  No failure on the part of the Company to exercise, no delay in
exercising, and no course of dealing with respect to, any right or remedy
hereunder will operate as a waiver thereof.  No single or partial exercise of
any right or remedy hereunder will preclude any further exercise of any other
right or remedy.  The rights and remedies of the Company provided herein are
cumulative and are in addition to, and not exclusive of, any rights or remedies
provided by law or otherwise.

14.

Wherever possible each provision of this Guaranty shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of this Guaranty shall be prohibited by or invalid under such law, such
provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or the
remaining provisions of this Guaranty.
