A.           In
order to induce the Lenders and the Agent to enter into the Credit Agreement, Michael D. Herman, an individual (the “Pledgor”),
provided to the Agent, for the benefit of the Lenders, that certain Limited Guaranty and Suretyship Agreement, dated as of November
2, 2012 (the “Guaranty”) pursuant to which Pledgor, among other things, guarantees the payment and performance
of Borrowers’ Obligations up to the Maximum Guarantied Amount (as defined therein). As further inducement to the Agent and
the Lenders, Pledgor agreed to secure its obligations under the Guaranty by entering into that certain Pledge Agreement, dated
as of November 2, 2012 (the “Herman Pledge Agreement”), pursuant to which Pledgor pledged to Agent, for the
benefit of the Lenders, 250,000 shares of common stock of Pyramid Oil Company. Borrowers and Pledgor have requested that Agent
terminate the Herman Pledge Agreement and release Pledgor from his obligations to pledge such Pyramid Oil Company stock.


 


B.           Upon
the effectiveness of this Agreement, Agent (a) releases and discharges Pledgor from all obligations arising under the Herman Pledge
Agreement, (b) terminates and cancels the Herman Pledge Agreement, and (c) acknowledges and agrees that (i) Agent and the Lenders
have no further rights, privileges or remedies under the Herman Pledge Agreement, and (ii) that Pledgor has no further duties,
obligations or liabilities under the Herman Pledge Agreement. Notwithstanding the foregoing, the Guaranty shall remain in full
force and effect as written.


 


C.           Other
than the Herman Pledge Agreement, each Borrower and Guarantor hereby ratifies and acknowledges the continuing validity and enforceability
of the Loan Documents, including the Guaranty, and the obligations and first liens evidenced thereby. All terms, covenants, conditions
and provisions of such Loan Documents, including the Guaranty, shall be and remain in full force and effect as written.

D.           In
consideration for the foregoing release and termination of the Herman Pledge Agreement, Pledgor and each Borrower hereby remises,
releases, acquits, satisfies and forever discharges Agent and the Lenders, their agents, employees, officers, directors, predecessors,
attorneys and all others acting or purporting to act on behalf of or at the direction of Agent or the Lenders, of and from any
and all manner of actions, causes of action, suit, debts, accounts, covenants, contracts, controversies, agreements, variances,
damages, judgments, claims and demands whatsoever, in law or in equity, which any of such parties ever had, now has or, to the
extent arising from or in connection with any act, omission or state of facts taken or existing on or prior to the date hereof,
against Agent and the Lenders, their agents, employees, officers, directors, attorneys and all persons acting or purporting to
act on behalf of or at the direction of Agent or the Lenders (“Releasees”), for, upon or by reason of any matter,
cause or thing whatsoever through the date hereof. Without limiting the generality of the foregoing, each of Pledgor and each
Loan Party waives and affirmatively agrees not to allege or otherwise pursue any defenses, affirmative defenses, counterclaims,
claims, causes of action, setoffs or other rights they do, shall or may have as of the date hereof, including, but not limited
to, the rights to contest any conduct of Agent, the Lenders or other Releasees on or prior to the date hereof. Each of the releasing
parties hereby waives California Civil Code § 1542, which provides: “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH
THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM
OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.” On the date hereof, each of the releasing parties
also shall be deemed to waive any and all provisions, rights and benefits conferred by any law of any state or territory of the
United States, or country in the world, or principle of common law, which is similar, comparable or equivalent to California Civil
Code § 1542. Any reference to the California Civil Code is out of an abundance of caution and shall not be construed to imply
a choice of law inconsistent with the governing law as selected in Section 16.1 of the Credit Agreement.
