Holder's Conversion Rights. At any time after the Issuance Date, the Holder shall be entitled to convert all of the outstanding and unpaid principal and accrued interest of this Note into fully paid and non-assessable shares of Common Stock in accordance with the stated Conversion Price. The Holder shall not be entitled to convert on a Conversion Date that amount of the Note in connection with that number of shares of Common Stock which would be in excess of the sum of the number of shares of Common Stock issuable upon the conversion of the Note with respect to which the determination of this provision is being made on a Conversion Date, which would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock of the Company on such Conversion Date. For the purposes of the provision to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder. Subject to the foregoing, the Holder shall not be limited to aggregate conversions of 4.99% ("Conversion Limitation 1"). The Holder shall have the authority to determine whether the restriction contained in this [Section 2(b)] will limit any conversion hereunder, and accordingly, the Holder may waive the conversion limitation described in this [Section 2(b)], in whole or in part, upon and effective after 61 days prior written notice to the Company to increase or decrease such percentage to any other amount as determined by Holder in its sole discretion ("Conversion Limitation 2").

Holder's Election. Holder's failure to exercise the election described in this Section 4 with respect to any event of default shall not constitute a waiver of the right to exercise such election upon the occurrence of any subsequent default.

CONVERSION RIGHTS. This Note shall be convertible at the option of the Holder into shares of Common Stock at any time on or prior to the Maturity Date or earlier repayment pursuant to [Section 1].

Holder shall be entitled to deduct $500.00 from the conversion amount in each Notice of Conversion to cover Holder's deposit fees associated with each Notice of Conversion.

Termination of Conversion Rights. In the event of a liquidation, dissolution, or winding up of the Corporation or a Liquidation Event, the Conversion Rights shall terminate at the close of business on the last full day preceding the date fixed for payment of any amounts distributable to the Holders of Series C Preferred Stock by reason of such event.

Consent and Conversion Rights. During the Period of Restriction, Employees holding Restricted Notes may exercise full consent and conversion rights with respect to those Restricted Notes, unless the Award Agreement provides otherwise.

Conversion. The Holders of the Series D Preferred Stock shall have conversion rights as follows (the “Conversion Rights”):

Commencing on the date hereof , the Holder may at any time prior to 5:00 p.m., Pittsburgh time, on December 20, 2024, convert the principal amount of this Note or any portion of the original principal amount outstanding under this Note on the date of its initial issuance (unless such amount is the only amount then remaining outstanding under this Note in which event the conversion of the remaining principal amount then outstanding shall be permitted) into fully paid and nonassessable shares of the Borrowers restricted Common Stock, par value $.0001 per share (the “Common Stock”), on the basis of one share of such stock for each $ Twenty Cents ($.20) (the “Conversion Price”) in principal amount and any accrued but unpaid interest of this Note. Such conversion shall be effected by the surrender of this Note at the principal office of the Borrower (or such other office or agency of the Borrower in the continental United States as the Borrower may designate by notice in writing to the Holder) at any time during usual business hours, together with notice in writing that the Holder wishes to convert a portion or all of this Note, which notice shall also state the name(s) (with addresses) and denominations in which the certificate(s) for Common Stock shall be issued and shall include instructions for delivery thereof. Such conversion shall be deemed to have been effected as of the close of business on the date on which this Note shall have been surrendered and such notice shall have been received, and at such time (the “Voluntary Conversion Date”) the rights of the Holder with respect to the principal amount of the Note converted shall cease and the person(s) in whose name(s) any certificate(s) for Common Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Common Stock represented by such certificate(s). As soon as practicable after the Voluntary Conversion Date, the Borrower shall deliver to, or as directed by, the Holder, certificates representing the number of shares of Common Stock issuable by reason of such conversion registered in such name or names and such denomination or denominations as the Holder shall have specified, together with cash as provided in [Section 8] in respect of any fraction of a share of such stock otherwise issuable upon such conversion. The Borrower shall also make payment to the Holder of accrued interest to the date of conversion on the portion of the Note converted in accordance with the manner of payment provisions of Section 1 of this Note. In each case of conversion of this Note in part only, the Borrower shall receive and hold this Note as a fiduciary agent of the Holder, shall endorse on this Note the date and amount of this Note so converted, and such amount shall be deemed no longer outstanding. Upon such endorsement, the Borrower shall promptly return this Note to the Holder.

Conversion. The Investor has the right, at any time after the Effective Date, at its election, to convert all or part of the outstanding and unpaid Principal Sum and accrued interest (and any other fees) into shares of fully paid and non-assessable shares of common stock of the Issuer as per this conversion formula: Number of shares receivable upon conversion equals the dollar conversion amount divided by the Conversion Price. Conversion notices may be delivered to the Issuer by method of the Investor's choice (including but not limited to email, facsimile, mail, overnight courier, or personal delivery), and all conversions shall be cashless and not require further payment from the Investor. If no objection is delivered from the Issuer to the Investor regarding any variable or calculation of the conversion notice within 24 hours of delivery of the conversion notice, the Issuer shall have been thereafter deemed to have irrevocably confirmed and irrevocably ratified such notice of conversion and waived any objection thereto. The Issuer shall deliver the shares from any conversion to the Investor (in any name directed by the Investor) within 3 (three) business days of conversion notice delivery. The Investor, at any time prior to selling all of the shares from a conversion, may, for any reason, rescind any portion, in whole or in part, of that particular conversion attributable to the unsold shares and have the rescinded conversion amount returned to the Principal Sum with the rescinded conversion shares returned to the Issuer (under the Investor's and the Issuer's expectations that any returned conversion amounts will tack back to the original date of the Note).

Conversion. The Lender has the right to convert any portion of the loan into common shares of the company. The rate of conversion will be 20% less of the 5 day average price of the stock.
