GUARANTY

Healthcare of Today, Inc., a California corporation ("Guarantor") executes this Guaranty (this "Guaranty") in favor of Allezoe Medical Holdings, Inc. ("Allezoe") as of February 29, 2012.

BACKGROUND

A.

Simultaneously with the execution of this Guaranty, Allezoe is entering into a Stock Transfer Agreement (as the same may be amended, supplemented or restated from time to time, the "Transfer Agreement") with Guarantor, pursuant to which Allezoe will transfer and convey to Allezoe all of the shares of Organ Transport Systems, Inc., a Nevada corporation (“OTS”), representing all of the issued and outstanding shares of OTS.  Capitalized terms not defined in this Guaranty have the meanings given in the Loan Agreement; and

B.

OTS is indebted to Allezoe in the amount of $469,826.92 for funds advanced by Allezoe to OTS to support its operations (the “Debt”); and

C.

Allezoe previously assumed certain debt from OTS, primarily representing unpaid salaries accrued by OTS to its officers, with a total principal balance due of $1,474,945.97, plus accrued interest of $158,961.84 as more fully described on Schedule 1 (the “OTS Debts”); and

C.

Guarantor owns directly or indirectly all of the stock of OTS as a result of the closing of the Transfer Agreement and will benefit in a direct and substantial way from the repayment of the Debt and the OTS Debt (collectively the “Liabilities”); and

D.

Guarantor is executing this Guaranty as an inducement to Allezoe to enter into the Transfer Agreement and in consideration of loans, advances and financial accommodations previously made by Allezoe to or for the benefit of OTS.

BASED ON THE FOREGOING and other good and valuable consideration, the receipt and adequacy of which is acknowledged, Guarantor agrees as follows:

TERMS AND CONDITIONS

Table of Contents

1.

Guaranty.  Guarantor absolutely, unconditionally and irrevocably guaranties the full, complete and prompt payment and performance of all of the Obligations as primary obligor and not merely as surety, whether by acceleration or otherwise.  For certainty, the term "Obligations" as used in this Guaranty means the Debt and the OTS Debts, collectively referred to as the Liabilities, together with all existing and future loans, advances, debts, obligations and liabilities of OTS to Allezoe (including interest which is or will be payable by OTS), direct and indirect, contingent and absolute, however arising or created, whether joint, several or joint and several, acquired by assignment, purchase or otherwise.  This Guaranty is a guaranty of payment and not of collection.  Therefore, Allezoe can insist that Guarantor pay immediately, and Allezoe is not required to attempt to collect first from OTS, any collateral, or any other person liable for the Obligations.  The obligations of Guarantor under this Guaranty are unconditional and absolute, regardless of the unenforceability of any provision of any agreement between OTS and Allezoe, or the existence of any defense, setoff or counterclaim which OTS may assert.  Guarantor is jointly and severally liable with any other guarantor of the Obligations.  If Allezoe

elects to enforce its rights against less than all guarantors of the Obligations (or any portion thereof), that election will not release Guarantor from its obligations under this Guaranty.  The compromise or release of any of the obligations of any of the other guarantors or OTS will not serve to waive, alter or release Guarantor's obligations.  This Guaranty is not conditioned on anyone else executing a guaranty.

2.

Action Regarding OTS.  Allezoe can take any action against OTS, any collateral, or any other person liable for any of the Obligations it deems appropriate without the consent or approval of Guarantor.  Allezoe can release OTS or anyone else from the Obligations, either in whole or in part, or release any collateral, and need not perfect a security interest in any collateral.  Allezoe does not have to exercise any rights that they have against OTS or anyone else, or make any effort to realize on any collateral or right of set-off before enforcing its rights under this Guaranty.  If OTS requests additional loans or any other benefit, Allezoe may grant it and Allezoe may grant renewals, extensions, modifications and amendments of the Obligations and otherwise deal with OTS or any other person as Allezoe sees fit and as if this Guaranty were not in effect.  Guarantor's obligations under this Guaranty will not be released or affected by (a) any act or omission of Allezoe, (b) the voluntary or involuntary liquidation, sale or other disposition of all or substantially all of the assets of OTS, or any receivership, insolvency, bankruptcy, reorganization, or other similar proceedings affecting OTS or any of their assets, or (c) any change in the composition or structure of OTS or Guarantor, including a merger or consolidation with any other person or entity.  

3.

Rights Of Subrogation.  Guarantor agrees not to enforce any rights of subrogation, contribution, setoff, counterclaim or indemnification that it has or may acquire in the future against OTS, any entity liable for the Obligations, or any collateral, until the Obligations (other than contingent indemnification obligations) are fully and indefeasibly paid and Allezoe has no further obligation to make loans or advances to OTS.

4.

Waivers.  Guarantor:

(a)

waives any right it may have to receive notice of the following matters before Allezoe enforces any of its rights: (i) Allezoe's acceptance of this Guaranty, (ii) any loans or advances that Allezoe extends to OTS, (iii) OTS’ default, (iv) any demand, and (v) any action that Allezoe takes regarding OTS, anyone else, any collateral, or any liability, which it might be entitled to by law or under any other agreement.

waives the right to assert any claim against Allezoe, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Guaranty, any of the other Loan Documents or any undertaking or transaction contemplated by this Guaranty or the Loan Documents.
