“Event of Default” shall exist if any of the following occurs and is
continuing:

 

(a)  Covenants:
Any Pledgor shall fail to comply with any of the provisions hereof, and such failure continues for more than ten (10) days after
the date on which the Pledgor shall have received written notice of such failure from the Lender; or

 

(b)Warranties
or Representations: Any warranty, representation or other written statement by or on behalf of any Pledgor contained herein
or in any certificate, instrument or other statement furnished in compliance herewith or with the Loan Documents shall have been
false or misleading in any material respect when made; or

 

(c)  Collateral:
All or any part of the Collateral shall be attached or levied upon or seized in any legal proceeding, or held by virtue of any
lien or distress, in any case for a period in excess of twenty (20) days; or

 

(d)Events of Default
Under Loan Documents:Any “Event of Default” exists under and as defined in the Loan Documents.

 

 4.2 Remedies

 

At
any time during the continuance of an Event of Default, the Lender may take any or all of the following actions with respect to
the Collateral:

 

(a)  The
Lender may exercise all of the rights and remedies of a secured party under the Uniform Commercial Code and other applicable law
and all of the rights and remedies conferred hereby, it being expressly understood that no such remedy is intended to be exclusive
of any other remedy or remedies, but each and every remedy shall be cumulative and shall be in addition to every other remedy given
herein or now or hereafter existing at law or in equity or by statute, and may be exercised from time to time as often as may be
deemed expedient by the Lender.

 

(b)  The
Lender shall have the right, subject to the mandatory requirements of applicable law, to sell or otherwise dispose of all or any
part of the Collateral, at public or private sale or at any broker’s board or on any securities exchange, for cash, upon
credit or for future delivery as the Lender shall deem appropriate. Each purchaser at any such sale shall hold the Collateral sold
absolutely free from any claim or right on the part of the Pledgor, and the Pledgor hereby waives (to the extent permitted by law)
all rights of redemption, stay and appraisal that the Pledgor now has or may at any time in the future have under any rule of law
or statute now existing or hereafter enacted.

 

 4.3 Method of Sale and Conduct of Remedies

 

(a)  The
Pledgor and the Lender agree that ten (10) days’ notice to any Pledgor of any or private sale or other disposition of the
Collateral or any portion thereof shall be reasonable notice thereof, and such sale shall be at such locations as the Lender shall
designate in such notice and during ordinary business hours, and any other requirement of notice, demand or advertisement for sale,
to the extent permitted by law, is hereby waived by the Pledgor. The Lender shall have the right to bid at any public sale.

 

    	 	-5-	 

     

    

 

(b)  The
Lender shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that
notice of sale of such Collateral shall have been given. The Lender may, without notice or publication, adjourn any public or private
sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may,
without further notice, be made at the time and place to which the same was so adjourned.

 

(c)  In
case any sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained
by the Lender until the sale price is paid by the purchaser or purchasers thereof, but the Lender shall not incur any liability
in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure,
such Collateral may be sold again upon like notice.

 

 4.4 Certain Securities Law Restrictions

 

Anything
herein to the contrary notwithstanding, and in view of the fact that federal and state securities laws may impose certain restrictions
on the method by which a sale of any securities constituting all or part of the Collateral may be effected after and during the
continuance of an Event of Default, the Pledgor agrees that, if an Event of Default shall exist hereunder, the Lender may, from
time to time, attempt to sell all or any part of any such securities by means of a private placement, restricting the bidders and
prospective purchasers to those who will represent or agree as to their investment intent or method of resale or both in a manner
reasonably required by the Lender to assure compliance with applicable securities laws. In so doing, the Lender may solicit offers
to buy such securities or any part thereof, for cash, from a limited number of investors deemed by the Lender to be responsible
parties who might be interested in purchasing such securities. If the Lender solicits such offers from not fewer than three (3)
such investors, then the acceptance by the Lender of the highest offer obtained therefrom shall be deemed to be a commercially
reasonable method of disposition of such securities.

 

 4.5 Lender Appointed Attorney-in-Fact

 

The
Pledgor hereby appoints the Lender as the Pledgor’s attorney-in-fact, with full authority to act in the place and stead of
the Pledgor and in the name of the Pledgor or otherwise at any time after an Event of Default shall exist, to take any action and
to execute any instrument which the Lender may deem necessary or advisable to accomplish the purposes of this Agreement, including,
without limitation:

 

(a)  to
ask, demand, collect, sue for, recover, compound, receive and give acquittance and receipts for moneys due and to become due under
or in respect of any of the Collateral,

 

    	 	-6-	 

     

    

 

(b)  to
receive, endorse and collect all instruments made payable to the Pledgor representing any payment or Distribution in respect of
the Collateral or any part thereof and to give full discharge for the same, and

 

(c)  to
file any claims or take any action or institute any proceedings that the Lender may deem necessary or desirable for the collection
of any of the Collateral or otherwise to enforce the rights of the Lender with respect to any of the Collateral.

 

The Pledgor
agree that the Lender shall not have any liability for any acts of commission or omission, or for any error of judgment or mistake
of fact or law, with respect to the exercise of the powers of attorney granted under this Section 4.5, unless such liability shall
be due to the willful misconduct or gross negligence of the Lender. The powers of attorney granted under this Section 4.5 are coupled
with and interest and shall be irrevocable for so long as any of the Obligations shall not have been fully and finally paid.

 

 4.6 Performance by the Lender for the Pledgor

 

If
any Pledgor shall fail to do any act or thing that it has covenanted to do hereunder, or any representation or warranty of the
Pledgor shall be breached, the Lender, may at its option, but shall not be required to, do the same or cause it to be done, or
remedy any such breach, and charge the Pledgor therefor, and the Pledgor agrees to promptly reimburse the Lender therefor, with
interest at an interest rate per annum that is then borne by the Pledgor pursuant to the terms of the Note. The Pledgor shall pay
all sums so paid or incurred by the Lender in respect of any of the foregoing and all costs and expenses (including attorneys’
fees, legal expenses and court costs) that the Lender may incur in asserting, enforcing, defending or protecting the Security Interest
herein granted on, or rights and interest in, the Collateral, or any of their rights or remedies under this Agreement or in respect
of any of the transactions to be had hereunder and, until paid by the Pledgor with interest at the rate aforesaid, such sums shall
be secured by all of the Collateral and the proceeds from the sale thereof.

 

5.  Effect
of Sale, etc.

 

5.1Title.Any
sale or sales pursuant to the provisions of this Agreement, whether under any right or power granted hereby or pursuant to any
legal proceedings, shall operate to divest the Pledgor of all right, title, interest, claim and demand whatsoever, either at law
or in equity, of, in and to the Collateral, or any part thereof, so sold, and any property so sold shall be free and clear of any
and all rights of redemption by, through or under the Pledgor.

 

5.2  Application
of Proceeds. The receipt by the Lender, or by any party authorized under
any judicial proceedings to make any such sale, of the proceeds of any such sale shall be a sufficient discharge to any purchaser
of the Collateral, or of any part thereof, sold as aforesaid; and no such purchaser shall be bound to see to the application of
such proceeds, or be bound to inquire as to the authorization, necessity or propriety of any such sale. In the event that, at any
such sale, the Lender is the successful purchaser, it shall be entitled, for the purpose of making settlement or payment, to credit
against the purchase price of such sale all or any portion of the Obligations.

 

    	 	-7-	 

     

    

 

 5.3 Restoration of Rights and Remedies

 

If
the Lender shall have instituted any proceeding to enforce any right or remedy hereunder, and such proceeding shall have been discontinued
or abandoned for any reason, or shall have been determined adversely to the Lender, then and in every such case, the Lender shall,
subject to any determination in any such proceeding, be restored severally and respectively to its former position hereunder, and
thereafter all rights and remedies of the Lender shall continue as though no such proceeding had been instituted.

 

 5.4 Application of Proceeds

 

The
proceeds of any exercise of rights with respect to the Collateral, or any part thereof, and the proceeds and the avails of any
remedy under this Agreement shall be paid to the Lender and applied by the Lender in accordance with the Note.

 

 5.5 Waivers by Pledgor

 

(a)Acceptance.
The Pledgor hereby waive notice of acceptance of this Agreement. The Pledgor further waives presentment and demand for payment
of any of the Obligations, protest and notice of dishonor or default with respect to any of the Obligations, and all notices to
which the Pledgor might otherwise be entitled, except as otherwise expressly provided in this Agreement.

 

(b)Waiver
of Valuations, etc. The Pledgor (to the extent that it may lawfully do so) covenants that it shall not at any time insist upon
or plead, or in any manner claim or take the benefit or advantage of, any stay, valuation, appraisal, redemption or extension law
now or at any time hereafter in force that, but for this waiver, might be applicable to any sale made hereunder or under any judgment,
order or decree based on this Agreement, and the Pledgor (to the extent that it may lawfully do so) hereby expressly waives and
relinquishes all benefit and advantage of any and all such laws and hereby covenants that it will not hinder, delay or impede the
execution of any power in this Agreement or therein granted and delegated to the Lender, but that it will suffer and permit the
execution of every such power as though no such law or laws had been made or enacted.

 

    	 	-8-	 

     

    

 

(c)Dealings with
Pledgor and Others.The Pledgor does hereby waive: notice of the extension of credit from time to time by Lender to Pledgor
and the creation, existence or acquisition of any Obligations hereby secured, including, without limitation, notice of the amount
of any indebtedness of Pledgor to Lender from time to time (subject, however, to Pledgor’s right to make inquiry of Lender
to ascertain the amount of such indebtedness at any reasonable time); notice of adverse change in Pledgor’s financial condition
or of any other fact which might increase such Pledgor’s risk hereunder; notice of presentment for payment, demand, protest
and notice thereof as to any instrument executed by Pledgor in favor of Lender; to the extent permitted under applicable law, notice
of default; and all other notices and demands to which the Pledgor might otherwise be entitled (except for any notices expressly
required under the Agreement). The Pledgor further waives any statutory or other rights to require Lender to institute suit against
Pledgor or any other obligor or guarantor in respect of the Obligations or to exhaust its rights and remedies against Pledgor or
any other such obligor or guarantor. The Pledgor accepts the full range of risk encompassed within a contract of continuing guaranty,
including the possibility that the Pledgor will incur indebtedness after its financial condition (including its ability to pay
debts when they fall due) has deteriorated. Pledgor waives the benefit of any applicable law having a contrary effect. The Pledgor
further waives any defense arising by reason of any disability or other defense of Pledgor or by reason of the cessation from any
cause whatsoever of the liability of Pledgor (except for payment in full of the Obligations), and any other legal or equitable
suretyship defense. Without limiting the foregoing, no Pledgor shall not be relieved of its obligations hereunder by virtue of
any time or indulgences granted by Lender to Pledgor. The Pledgor hereby irrevocably appoints Pledgor as the Pledgor’s agent
such that any agreement made between Lender and Pledgor with respect to any waiver, release or amendment of the terms of the Note
and any other Loan Documents, shall be deemed to have been agreed and consented to by the Pledgors and the execution of any document
by Pledgor evidencing any such agreement shall be deemed to have been executed by Pledgor as principal and as authorized agent
of the Pledgors. Until all of the Obligations shall have been satisfied in full, the Pledgors shall have no right of subrogation,
reimbursement or indemnity whatsoever and no right of recourse to or with respect to any assets or property of Pledgor or to any
collateral for the Obligations. Nothing shall discharge or satisfy the obligations secured hereby except the full payment of the
Obligations. As between the Pledgors and Lender and at the option of Lender, such Obligations shall forthwith become due and payable
if there shall be filed against any one or more of Pledgor or the Pledgors a petition under any bankruptcy, insolvency, reorganization
or arrangement or similar laws for appointment of a receiver or trustee, if any one or more of Pledgor or the Pledgors makes an
assignment for the benefit of creditors, or if an Event of Default shall exist. It is the intent of the parties that this Agreement
shall remain in full force and effect notwithstanding any act or thing that might otherwise operate as a legal or equitable discharge
of a surety.

 

 6. MISCELLANEOUS

 

 6.1 No Waiver

 

No
failure on the part of the Lender to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy by the Lender preclude any other
or further exercise thereof or the exercise of any other right, power or remedy. All remedies hereunder are cumulative and are
not exclusive of any other remedies provided by law. The Lender shall not be deemed to have waived any rights hereunder or under
any other agreement or instrument unless such waiver shall be in writing and signed by the Lender and the Pledgor.

 

    	 	-9-	 

     

    

 

 6.2 Lender’s Fees and Expenses

Pledgor will upon demand pay to the Lender the amount of any and all reasonable expenses, including the fees and expenses of its
counsel and of any experts or agents that the Lender may incur in connection with (i) the custody or preservation or, or the sale
of, collection from, or other realization upon, any of the Collateral, (ii) the exercise or enforcement of any of the rights of
the Lender hereunder, or (iii) the failure by the Pledgor to perform or observe any of the provisions hereof. In addition, the
Pledgor will indemnify and hold the Lender harmless from and against any and all liability incurred by the Lender hereunder or
in connection herewith, unless such liability shall be due to the willful misconduct or gross negligence of the Lender. Any such
amounts payable as provided hereunder or thereunder shall be secured hereby.

 

 6.3 Benefits of this Agreement

 

All warranties, representations
and covenants made by the Pledgor herein or in any certificate or other document or instrument delivered by it shall be considered
to have been relied upon by the Lender and shall survive the delivery to the Lender of the Collateral regardless of any investigation
made by the Lender. All statements in any such certificate or other instrument shall constitute warranties and representations
by the Pledgor hereunder. This Agreement shall be binding upon the Pledgor and their respective heirs and assigns, and shall inure
to the benefit of and be enforceable by the Lender and its successors and assigns.

 

 6.4 Obligations Absolute; Recourse; No Marshaling

 

(a)  This
Agreement is an absolute, unconditional, continuing and irrevocable obligation of the Pledgor and shall remain in full force and
effect without respect to future changes in conditions, including change of law or any invalidity or irregularity with respect
to the issuance of any obligations of Pledgor to Lender or with respect to the execution and delivery of any agreement between
Pledgor and Lender. The Pledgor further agrees that to the extent Pledgor makes a payment or payments to Lender, which payment
or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required,
for any of the foregoing reasons or for any other reason, to be repaid or paid over to a trustee, receiver or any other party under
any bankruptcy, insolvency or similar law, then, to the extent of such payment or repayment, the Obligations or part thereof intended
to be satisfied shall be revived and continued in full force and effect as if said payment had not been made.

 

(b)  Lender
shall have the right to seek recourse against the Collateral to the full extent provided for herein, which rights shall be absolute
and shall not in any way be impaired, deferred or otherwise diminished by reason of any inability of Lender to claim the full amount
of the Obligations from Pledgor under any applicable law. No election to proceed in one form of action or proceeding, or against
any party, or on any obligation, shall constitute a waiver of Lender’s right to proceed in any other form of action or proceeding
or against other parties unless Lender has expressly waived such right in writing. Specifically, but without limiting the generality
of the foregoing, no action or proceeding by Lender against Pledgor, any guarantor of the Obligations or any other party, under
any document or instrument evidencing or securing the Obligations shall serve to diminish the liability of the Pledgor hereunder,
except to the extent Lender fully and unconditionally realizes full indefeasible payment of the Obligations by such action or proceeding,
notwithstanding the effect of any such action or proceeding upon the Pledgor’s right of subrogation, reimbursement or contribution
against Pledgor or any other party.

 

    	 	-10-

        Convertible Notes (the “June 2017 Notes”) investment it made into Avant in June and August 2017 for a preferred share
        structure (Series A Preferred Shares, or “Series A”). Upon the investment of $750,000 by the Group, in whole or in
        part, the Series A is convertible into common shares that would result in the ownership of 49.99% of the then outstanding common
        shares of Avant by the holders of the Series A.

         

        The June 2017 Notes shall be amended to include an alternative
        conversion feature that describes the ability of the Group to exchange their Senior Secured Notes, Purchase Rights and Warrants
        into Preferred Shares at any time.

	Valuation:	
        $750,000.00 of the June 2017 Notes by the Group (or other permitted
        third parties) would exchange into Series A that is convertible into the equivalent of 49.99% of the outstanding common share structure
        of Avant (the “Common”) at the time of conversion (the “Beneficial Ownership Limitation”). The Common shall
        include issued preferred securities, and other securities that are not redeemable by the Company, but shall not include convertible
        debt or other securities that the Company may repurchase or redeem, so that the Beneficial Ownership Limitation is not breached
        and no change of control occurs. In the event outstanding convertible notes are converted common shares, those common shares would
        be added to the calculation of the Common.

         

        Any investment by the Group, including the $400,000 that is
        already invested, total less than $750,000.00 would receive a pro-rata amount of Series A (the “Ownership Rate”).

         

        As of the date of this term sheet,
Infusion has invested $325,000.00 into the June 2017 Notes, and Xpress has invested $75,000.00 into the June 2017 Notes. 

	Current Common Shares Outstanding	282,733,708
	49.99% of Fully Diluted  Common Share Structure	282,620,637
	Percentage of the $750,000.00 currently invested/Currently available to Exchange	Currently, $400,000 would convert to 53.33% (40/75 is 53.33) of the 49.99% ownership
	Avant securities owned by Infusion to be exchanged:	
        $325,000.00 Senior Secured Notes

        43,333,333 Purchase Rights

        10,833,333 Warrants 

	Avant securities owned by Xpress to be exchanged:	
        $75,000 Senior Secured Promissory Notes

        10,000,000 Purchase Rights

        2,500,000 Warrants

        

	Avant Preferred Share Issuance

	The Series A will have the following characteristics:

 

1.    Series
A converts into common shares at the Ownership Ratio. The Ownership Ratio is based on the percentage of June 2017 Notes converted
into Series A where an investment of $750,000 is the equivalent of 49.99% of the Common, which as August 23, 2017 is 282,733,708.

        2.    As
        of August 23, 2017 the Ownership Ratio is 53.33% as $400,000 of the $750,000 has been invested.

         

        3.    Any
        future investments into the June 2017 Notes and conversion into the Series A will result in the issuance of the Series A shares
        at the Ownership Ratio.

         

        4.    Any
        conversion by Infusion of its Series A will reduce the Ownership Ratio by the percentage of Series A converted.

         

        5.    Any
        future issuance of common shares, or in derivatives that convert into common that are a part of the Common, will still be subject
        to the Ownership Ratio. 

         

	Total Series A Preferred Shares	4999 Series A preferred shares
	Preferred Share Conversion Rate	Each Series A preferred shares is convertible into 0.01% of the outstanding Common at the time of conversion. In the event multiple conversions are made by the Group, each share of Series A may be convertible into different amounts of common stock of Avant.
	Preferred Share Voting Rights	The Series A will vote together with the common stock and not as a separate class except as specifically provided herein or as otherwise required by law. Each Series A share shall have a voting right equivalent to the amount of common shares it can convert into.

        As long as Xpress owns enough Preferred Shares
that would result in Xpress’ right to convert into 10% ownership of Avant’s common shares, it shall have the right
to place two directors on the Board of Directors of Avant, including the right to replace any vacancies of those directors.

         

        The Board shall not be increased
beyond 9 members without the prior written consent of the Holder of the majority of the Preferred Shares.

	Right of First Refusal	The
Preferred Shares shall contain a right of first refusal which shall allow the Group, or either member of the Group to invest into
Avant under the same terms of any bona fide investment offer made to Avant, up to the maximum amount of their investment.  
In the event that the Group declines to exercise its Right of First Refusal, the Group may exercise its Most-Favored Nation rights
described below.   

	Most Favored Nation	
        As long as the Group owns the Preferred Shares, if Avant engages
        in any future financing transactions with a third-party investor, Avant will provide the Group with written notice (the “MFN
        Notice”) thereof promptly but in no event less than 10 days prior to closing any financing transactions. Included with
        the MFN Notice shall be a copy of all documentation relating to such financing transaction and shall include, upon written request
        of the Group, any additional information related to such subsequent investment as may be reasonably requested by the Group. In
        the event the Group determines that the terms of the subsequent investment are preferable to the terms of the Preferred Shares
        issued to the Group, the Group will notify Avant in writing. Promptly after receipt of such written notice from the Group, Avant
        agrees to amend or replace the Preferred Shares, and, to be identical to the instruments evidencing the subsequent investment.

         

        The Group may exercise its Most Favored Nation clause in relation
        to either or both of its 2017 Notes or Preferred Shares, in all or in part. Should the Group exercise its Most Favored Nation clause,
        the Group’s investment that is being converted pursuant to the Most Favored Nation clause with Avant will be multiplied by
        two.

        Avant shall include on the next
registration statement Avant files with the SEC (or on the subsequent registration statement if such registration statement is
withdrawn) all shares issuable upon conversion of any or all Preferred Shares that the Group, in its sole discretion, may direct
Avant to include, and any restricted common shares granted that the Group then owns. 

	Restrictions on Future Issuances to Third Parties	Avant
shall not, directly or indirectly, without the prior written consent of the holders of a majority of the Preferred Share then
outstanding, issue any securities, debt or equity (other than as contemplated in this term sheet). 

	Security on AVDX Intellectual Property	
        The Group shall maintain its senior position on the secured
        intellectual property by virtue of the June 2017 Notes; The Event of Default under the Security and Pledge Agreement will be amended
        to include “failure to achieve an increase in authorized common shares underlying the Series A prior to December 31, 2017”.

         

        The Group shall vote to approve
an increase in authorized common shares. 

	No Variable Rate Transactions.	While the Preferred Shares are outstanding, Avant shall not enter into any variable rate transactions.   “Variable Rate Transaction” means a transaction in which  Avant (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive, additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that is based upon, and/or varies with, the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of Avant or the market for the Common Stock or (ii) enters into any agreement, including, but not limited to, an equity line of credit, whereby Avant may sell securities at a future determined price.

                                         be entitled to receive in preference to the holders of the Common Stock a per share amount
                                         equal to the greater of: (i) the amount exchanged and or paid and invested by the Group
                                         for the Preferred Share plus any declared but unpaid dividends  or (ii) the
                                         amount such holder would have received had the shares of Preferred Stock been converted
                                         into Common Stock immediately prior to the liquidation or winding up (the “Liquidation
                                         Preference”) 

	Restriction on Issuance	There
will be a restriction on issuing common or preferred shares to any party if the issuance would result in that party owning in
excess of 49.99% of the voting securities of Avant. 

	Senior Secured Note	
        June 2017 Notes will be amended to include a requirement that
        Avant provide seven days written notice of prepayment.

         

        The June 2017 Notes will also
be amended to permit its holder the option whether to accept any payments of principal, whether prepayment or not, or deny and
affirmatively delay payment of any amounts due. 

	Fees and Expenses	Avant agrees to pay the Group’s legal fees and expenses related to work performed for Avant, including this transaction.

 

The purpose of this Term Sheet is to express the mutual intent
of the parties hereto to proceed in good faith and as expeditiously as possible towards consummation of the transaction on such
terms and conditions summarized herein. Therefore, it is intended as a basis for guidance to legal counsel for the preparation
of definitive documentation in support of the proposed transaction; however, it is intended to be a legally binding obligation.
