AGREEMENT

 

NOW THEREFORE, in consideration
of the foregoing and the mutual covenants set forth herein, the parties hereto hereby agree as follows:

 

    	 

    	 

    

 

1.          Appointment.
The Parties hereby appoint the Escrow Agent as their escrow agent for the purposes set forth herein, and the Escrow Agent hereby
accepts such appointment under the terms and conditions set forth herein.

 

2.          Escrow
Account.

 

(a)         On
or as soon as practicable after the date hereof, Parent will cause 1,016,746 shares of common stock of Parent, par value $0.0001
per share (the “Parent Common Stock”), which shares shall be registered in the name of Escrow Agent f/b/o
the Merger Securityholders (the “Escrow Shares”), to be delivered to the Escrow Agent in book-entry form,
and the Escrow Agent will acknowledge receipt of the Escrow Shares to Parent and the Stockholders’ Agent promptly upon receipt
thereof. Subject to the terms and conditions of this Escrow Agreement, the Escrow Agent shall hold the Escrow Shares and shall
invest, reinvest and manage any cash proceeds thereof as directed in Section 3(d) (the “Proceeds,”
and the Escrow Shares and the Proceeds, collectively, the “Escrow Account”). Upon receipt of the Escrow
Shares, the Escrow Agent shall not release the Escrow Shares or the rest of the Escrow Account except in accordance with this Escrow
Agreement.

 

(b)          If
Parent at any time or from time to time between the date of this Escrow Agreement and the final disposition of the Escrow Account
in accordance with this Escrow Agreement, (i) subdivides (by any stock split, stock dividend, recapitalization or otherwise) its
outstanding shares of Parent Common Stock into a greater number of shares, or (ii) combines (by reverse stock split or otherwise)
its outstanding shares of Parent Common Stock into a smaller number of shares, then Parent will deliver notice thereof to the Escrow
Agent, and, unless the applicable authorizing resolutions of the Board do not require delivery of new Escrow Shares as a result
of such action, the Parent will as promptly as practicable after the effective date with respect thereto deliver to the Escrow
Agent in book-entry form the requisite Escrow Shares as may be required to reflect the applicable increase or reduction, as the
case may be, of such Escrow Shares. The Escrow Agent shall be entitled to execute and deliver any transmittal letter or other documents
and share certificates required to effectuate an exchange of shares if contemplated by the action taken pursuant to the preceding
clauses (i) or (ii). If Parent at any time or from time to time between the date of this Escrow Agreement and the final disposition
of the Escrow Account in accordance with this Escrow Agreement pays any distribution or dividend in respect of the Escrow Shares
in additional shares of Parent Common Stock, then Parent will deliver notice thereof to the Escrow Agent and the Stockholders’
Agent, and, unless the applicable authorizing resolutions of the Board do not require delivery of additional Escrow Shares as a
result of such action, the Parent will as promptly as practicable after the payment date with respect thereto deliver to the Escrow
Agent additional Escrow Shares representing such additional shares of Parent Common Stock. Upon such delivery referred to in this
Section 2(b), the Escrow Agent shall hold such additional or substitute Escrow Shares, and all such shares are deemed Escrow
Shares for purposes of this Escrow Agreement.

 

    	- 2 -

    	 

    

 

(c)          This
Agreement assumes that the Escrow Account will at all times be comprised only of Parent Common Stock and/or cash. If the Parent
Common Stock is converted into any securities or other property other than Parent Common Stock, or any securities or other property
(in each case, other than cash or additional shares of Parent Common Stock) are distributed, issued or exchanged with respect to
any shares of Parent Common Stock (then held in the Escrow Account) upon any recapitalization, reclassification, merger, consolidation,
stock dividend or the like, or if for any other reason securities or other property (in each case, other than cash or additional
shares of Parent Common Stock) at any time are held in the Escrow Account, Parent and the Stockholders’ Agent shall negotiate
in good faith, and execute and deliver, such supplemental written instructions to the Escrow Agent as are necessary to account
for such other securities or property in a manner consistent with the results that would have prevailed if only Parent Common Stock
and/or cash were held in the Escrow Account, and shall deliver such supplemental written instructions to the Escrow Agent. If the
Parties are unable to agree on any such supplemental instructions contemplated by the preceding sentence within thirty (30) days
after such sentence shall become applicable, then the Escrow Agent shall refrain from taking any action with respect to such property
other than Parent Common Stock and/or cash, other than to keep safely such other property until it shall be directed otherwise
in writing jointly by Parent and the Stockholders’ Agent or by final non-appealable order of a court of competent jurisdiction.
The Escrow Agent shall be entitled to execute and deliver any transmittal letter or other documents and Escrow Shares required
in connection with such any recapitalization, reclassification, merger, consolidation or similar event to receive any shares of
stock, securities, properties or cash in exchange for Escrow Shares.

 

(d)          Notwithstanding
 anything  to  the  contrary contained herein and for so long as the Escrow Shares remain in the Escrow Account,
the Parties agree that the Merger Securityholders shall have the right to (i) vote all  Escrow Shares that are not disbursed
to Parent pursuant to the terms hereof, (ii) receive any cash dividends and cash distributions in respect of the Escrow Shares
that are not disbursed to Parent pursuant to the terms hereof, and (iii) except as set forth in Section 2(e) below, exercise any
and all other rights of a shareholder of Parent with respect to the Escrow Shares that are not disbursed to Parent pursuant to
the terms hereof; provided however, that Parent shall not be obligated to recognize any sale of Escrow Shares to a
third party prior to the termination of this Escrow Agreement in accordance with the terms hereof.

 

(e)          Notwithstanding
anything to the contrary contained herein, to the extent that Parent makes any non-cash distributions or non-cash dividends in
respect of the Escrow Shares while such Escrow Shares remain in the Escrow Account, such distributions and dividends shall be deposited
into the Escrow Account by Parent. Upon any disbursement of the Escrow Shares to Parent or the Merger Securityholders pursuant
to Sections 4 or 5 (as the case may be), the non-cash distributions and non-cash dividends held in the Escrow Account in respect
of such disbursed Escrow Shares shall be disbursed to the Party receiving such disbursed Escrow Shares.

 

3.          Investment
of Escrow Account.

 

(a)        The
Parties recognize and agree that the Escrow Agent will not provide supervision, recommendations or advice relating to either the
investment of moneys or any other assets held in the Escrow Account or the purchase, sale, retention or other disposition of any
investment described herein. The Escrow Agent shall not liquidate, sell, invest or reinvest any portion of the Escrow Account except
as provided herein and shall hold the Escrow Shares and any cash or other assets received in respect thereof in the form initially
received, except as provided herein. The Escrow Agent shall not have any liability for any loss sustained as a result of any investment
or the failure to make an investment made pursuant to the terms of this Escrow Agreement.

 

    	- 3 -

    	 

    

 

(b)          During
the term of this Escrow Agreement, any cash in the Escrow Account shall be invested in a money market deposit account or a successor
or similar investment offered by the Escrow Agent and approved by the Stockholders’ Agent and Parent, unless otherwise instructed
in writing by the Parties and as shall be reasonably acceptable to the Escrow Agent. The Escrow Agent will provide compensation
on balances in the Escrow Account at the then-applicable rate for such account or investment from time to time. Written investment
instructions, if any, shall specify the type and identity of the investments to be purchased and/or sold. The Escrow Agent is hereby
authorized to execute purchases and sales of investments through the facilities of its own trading or capital markets operations
or those of any affiliated entity. The Escrow Agent or any of its affiliates may receive reasonable compensation with respect to
any investment directed hereunder including without limitation charging a reasonable agency fee in connection with each transaction.
The Parties recognize and agree that the Escrow Agent will not provide supervision, recommendations or advice relating to either
the investment of moneys held in the Escrow Account or the purchase, sale, retention or other disposition of any investment described
herein. The Escrow Agent shall not have any liability for any loss sustained as a result of any investment in an investment made
pursuant to the terms of this Escrow Agreement or as a result of any liquidation of any investment prior to its maturity or for
the failure of the Parties to give the Escrow Agent instructions to invest or reinvest the Escrow Account.

 

4.          Disbursement
of Escrow Account. The Parties agree that the Escrow Account is available to satisfy the Merger Securityholders’ indemnification
obligations set forth in Section 10 of the Merger Agreement. On the next successive business day after the Claims Deadline (as
defined below), the Escrow Agent shall release all of the Escrow Account to Exchange Agent for the benefit of the Merger Securityholders,
less any unresolved Dispute Amounts (as defined below) and any amounts previously released in accordance with Section 5
hereof.

 

5.          Indemnification
Claims.

 

(a)         If
a Parent Indemnified Party wishes to make a claim for indemnification pursuant to Section 10 of the Merger Agreement, Parent, on
behalf of such Parent Indemnified Party, shall promptly deliver a notice (a “Claim Notice”) to the Stockholders’
Agent and the Escrow Agent. The Claim Notice shall state (i) the dollar amount of any indemnification asserted to be owed under
Section 10 of the Merger Agreement, (ii) the number of Escrow Shares necessary to satisfy the indemnification amount owed, (iii)
a statement of the facts giving rise to such claim for indemnification, and the specific representations, warranties or covenants,
if any, alleged to have been breached, and (iv) that a claim for such indemnification has been made in accordance with the terms
of the Merger Agreement (including, but not limited to, Section 10 thereof).

 

(b)          Subject
to Section 5(c), on the thirtieth (30th) day following receipt by the Escrow Agent of the Claim Notice (or if such day is
not a business day, then on the next successive business day), the Escrow Agent shall release the number of Escrow Shares described
in the Claim Notice to Parent from the Escrow Account, less the amount, if any, described in a Dispute Notice (as defined below).
If the Escrow Account contains both Escrow Shares and cash, any such payment shall be made to Parent in Escrow Shares and cash,
such that the ratio of cash paid to Escrow Shares released is equal to the ratio of cash to Escrow Shares in the Escrow Account
as of the date of such payment. For purposes of distributing the Escrow Account pursuant to the terms hereof, the Escrow Shares
shall be valued at the Parent Share Price.

 

    	- 4 -

    	 

    

 

(c)          During
the thirty (30) days following the Escrow Agent’s receipt of the Claim Notice, the Stockholders’ Agent may deliver
a written notice to the Escrow Agent and Parent disputing any or all of the claims made in the Claim Notice (a “Dispute
Notice”), which such Dispute Notice shall state with reasonable specificity the nature of the dispute and the portion
of the claim stated in the Claim Notice that is the subject of such dispute (such amount, the “Disputed Amount”).
The Escrow Agent shall not distribute the Disputed Amount until (i) the Escrow Agent receives a certified copy of a final non-appealable
judgment issued by a court of competent jurisdiction, ordering the distribution of all or a portion of the Disputed Amount, or
(ii) directed to do so pursuant to written instructions executed by Parent and the Stockholders’ Agent. The rights of the
Escrow Agent under this Section 5(c) are cumulative of all other rights it may have by law or otherwise. Any claim by Parent
disputed by the Stockholders’ Agent pursuant to this Section 5(c), or any claim by Parent which the Escrow Agent has
refused to comply with or take any action in connection with in accordance with this Section 5(c), shall be referred to
herein as a “Disputed Claim.” The Escrow Agent shall not be liable in any way or to any Person for its
failure or refusal to release such Disputed Amount.

 

(d)          Promptly
following resolution of all or any portion of a Disputed Claim in favor of the former Merger Securityholders, Parent shall provide
written notice to the Escrow Agent that such Disputed Claim or portion thereof has been discharged, and to the extent any amounts
are being withheld from being disbursed to the Exchange Agent pursuant to the last sentence of Section 4 by the Escrow Agent
in respect of such Disputed Claim, such amount shall promptly be released to the Exchange Agent.

 

(e)          The
Parties agree that Parent shall have the right to make claims against the Escrow Account on behalf of itself and any of the other
Parent Indemnified Parties until the twelve (12) month anniversary of the Closing Date (the “Claims Deadline”).

 

6.          Disposition
and Termination. Upon delivery of the Escrow Account by the Escrow Agent in accordance with Sections 4 and 5
above, this Escrow Agreement shall terminate, subject to the provisions of Sections 7(b), 7(c), 7(g) and 8.

 

7.          Concerning
the Escrow Agent.

 

(a)         Good

of its own best judgment, and may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate,
opinion or advice of counsel (including counsel chosen by the Escrow Agent, which counsel may be company counsel), statement, instrument,
report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also
as to the truth and acceptability of any information therein contained) which is reasonably believed by the Escrow Agent to be
genuine and to be signed or presented by the proper person or persons. The Escrow Agent shall not be bound by any notice or demand,
or any waiver, modification, termination or rescission of this Escrow Agreement unless evidenced by a writing delivered to the

services of the Escrow Agent hereunder, or the Escrow Account held by it hereunder, other than expenses or losses arising from
the fraud, gross negligence or willful misconduct of the Escrow Agent. Promptly after the receipt by the Escrow Agent of notice
of any demand or claim or the commencement of any action, suit or proceeding, the Escrow Agent shall notify the other parties hereto
in writing. In the event of the receipt of such notice, the Escrow Agent, in its sole discretion, may commence an action in the
nature of interpleader in an appropriate court to determine ownership or disposition of the Escrow Account or it may deposit the
Escrow Account with the clerk of any appropriate court or it may retain the Escrow Account pending receipt of a final, non-appealable
order of a court having jurisdiction over all of the parties hereto directing to whom and under what circumstances the Escrow Account

(d)          Further
Assurances. From time to time on and after the date hereof, Parent and the Stockholders’ Agent shall deliver or cause

Agent, which approval will not be unreasonably withheld, conditioned or delayed, the Escrow Account held hereunder. If no new escrow
agent is so appointed within the sixty (60) day period following the giving of such notice of resignation, the Escrow Agent may
deposit the Escrow Account with any court it reasonably deems appropriate in the State of New York.

 

    	- 6 -

    	 

    

 

(f)          Discharge
of Escrow Agent. The Escrow Agent shall resign and be discharged from its duties as escrow agent hereunder if so requested

FORM OF LOCKUP AGREEMENT

 

THIS LOCKUP AGREEMENT
(this "Agreement") is made and entered into as of [_________], 2014, by and among MergeWorthRx Corp., a Delaware
corporation ("Parent"), and the undersigned Company Stockholder ("Seller"). Each capitalized
term used, but not otherwise defined, herein has the respective meaning ascribed to such term in the Agreement and Plan of Merger
and Reorganization, dated as of October 14, 2014, by and among Parent, AeroCare Holdings, Inc., a Delaware corporation, and the
other parties thereto (the "Merger Agreement").

 

In connection with
the consummation of the transactions contemplated by the Merger Agreement and for good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged and agreed, Seller and Parent hereby agree as follows:

 

1.          The
execution and delivery of this Agreement is a condition to the performance of the
parties' obligations under the Merger Agreement, including the delivery of the shares of Parent Common Stock issued to the
Seller pursuant thereto (the "Shares").

 

2.          Seller
hereby acknowledges and agrees that during the Lockup Period (as defined below), as applicable to those Shares which remain subject
to the Lockup Period from time to time (as set forth below), it shall not (A) sell, offer to sell, contract or agree to sell, hypothecate,
pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase
a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange
Act with respect to any portion of such Shares, (B) enter into any swap or other arrangement that transfers to another, in whole
or in part, any of the economic consequences of ownership of any such Shares, whether any such transaction is to be settled by
delivery of such Shares or such other securities, in cash or otherwise, or (C) publicly announce any intention to effect any transaction
specified in clause (A) or (B). As used herein, the term "Lockup Period" means the period beginning on the Closing
Date and ending on the earlier of: (a) (i) with respect to fifty percent (50%) of the Shares, the six month anniversary of the
Closing Date, and (ii) with respect to the remaining fifty percent (50%) of the Shares, the twelve month anniversary of the Closing
Date and (b) the date that Parent consummates a liquidation, merger, stock exchange or other similar transaction that results in
all of the holders of Parent Common Stock having the right to exchange their shares of Parent Common Stock for cash, securities
or other property.

 

3.     
     Notwithstanding the provisions of paragraph 2, above, each Seller may transfer any or
all of its Shares:

 

(a)          to
the officers, directors or employees of Parent;

 

(b)          if
Seller is an entity, to any person which, directly or indirectly, controls, is controlled by or is under common control with such
Seller, including, without limitation, any partner, officer, director or member of such Seller and, with respect to any Seller
that is a private investment fund, to any person which is controlled by or under common control with one or more general partners
of such Seller;

 

(c)          to
Seller’s immediate family members and trusts for estate planning purposes;

 

(d)          by
virtue of the laws of descent and distribution upon Seller’s death; or

 

(e)          pursuant
to a qualified domestic relations order;

 

provided, however, that, in the case of
clauses (a) through (e), such permitted transferee(s) becomes bound by the transfer restrictions and forfeiture provisions contained
herein.

 

    	 

    	 

    

 

4.          In
furtherance of the foregoing, Seller hereby authorizes Parent during the Lockup Period to cause the transfer agent for the Parent
Common Stock to decline to transfer any Shares, and to place restrictive legends and note stop transfer restrictions on the Shares,
the stock register and other records relating to the Shares.

 

5.          Seller
hereby represents and warrants to Parent that (i) it has full power and authority to enter into this Agreement and (ii) this Agreement

6.          Parent
hereby represents and warrants to Seller that the lock-up restrictions set forth herein are no more restrictive to Seller than

7.          Parent
hereby covenants to Seller that, in the event that any of the Parent Lock-Up Restrictions are amended, waived or otherwise modified
in a manner that makes the lock-up restrictions set forth herein more restrictive to Seller than the Parent Lock-Up Restrictions,
this Agreement shall be promptly amended to be no more or less restrictive to Seller than such amended, waived or modified Parent
Lock-Up Restrictions; provided, that in no event shall the lock-up restrictions set forth herein extend beyond the 12 month anniversary
of the Closing Date. To the extent this Agreement is amended, waived or otherwise modified in a manner that makes the lock-up restrictions
set forth herein less restrictive to Seller, Seller acknowledges and agrees that Parent and Parent’s Sponsors shall be permitted
to amend, waive or otherwise modify the Parent Lock-Up Restrictions to be no more or less restrictive to Parent’s Sponsors
than such amended, waived or modified lock-up restrictions applicable to Seller set forth herein.
