Question: What type of agreement does Progressive parlay and Parlay have in common?

Context paragraphs:
Non-disclosure agreement: A non-disclosure agreement (NDA), also known as a confidentiality agreement (CA), confidential disclosure agreement (CDA), proprietary information agreement (PIA) or secrecy agreement (SA), is a legal contract between at least two parties that outlines confidential material, knowledge, or information that the parties wish to share with one another for certain purposes, but wish to restrict access to or by third parties.  It is a contract through which the parties agree not to disclose information covered by the agreement.  An NDA creates a confidential relationship between the parties to protect any type of confidential and proprietary information or trade secrets.  As such, an NDA protects non-public business information.

2006 Progressive Enterprises dispute: The 2006 Progressive Enterprises Dispute was an industrial dispute between New Zealand supermarket company Progressive Enterprises and employees represented by the National Distribution Union and the EPMU.  On 25 August 2006, over 500 employees at Progressive's four distribution centres (in Auckland, Palmerston North and Christchurch) began a 48-hour strike supporting a demand for a national collective agreement involving an eight percent wage increase and pay parity between the four centres.  On 26 August 2006 the company locked out the strikers indefinitely, suspending operations at its distribution centres, with suppliers delivering goods directly to the supermarkets and also setting up amateur small scale distribution centres in car parks of Countdown supermarkets.  The dispute was resolved on 21 September 2006 when Progressive Enterprises agreed to pay parity and a 4.5% wage increase.

Browse wrap: Browse-wrap (also Browserwrap or browse-wrap license) is a term used in Internet law to refer to a contract or license agreement covering access to or use of materials on a web site or downloadable product.  In a browse-wrap agreement, the terms and conditions of use for a website or other downloadable product are posted on the website, typically as a hyperlink at the bottom of the screen.  Unlike a clickwrap agreement, where the user must manifest assent to the terms and conditions by clicking on an "I agree" box, a browse-wrap agreement does not require this type of express manifestation of assent.  Rather, a web-site user purportedly gives his or her assent by simply using the product — such as by entering the website or downloading software.

Parlay (gambling): A parlay, accumulator, or combo bet is a single bet that links together two or more individual wagers and is dependent on all of those wagers winning together.  The benefit of the parlay is that there are much higher payoffs than placing each individual bet separately since the difficulty of hitting it is much higher.  If any of the bets in the parlay lose, the entire parlay loses.  If any of the plays in the parlay ties, or "pushes", the parlay reverts to a lower number of teams with the odds reducing accordingly.

Pre-consultation Agreement (Japan): A Pre-consultation Agreement (事前協議制 , jizenkyougizei ) is a type of agreement in Japan where a party will notify the other before taking certain actions.  This type of agreement can be reached between various parties, one example being the 1960 Treaty of Mutual Cooperation and Security between the United States and Japan, where the US agreed to consult Japan before making large changes to its forces in Japan.

Click wrap: A clickwrap agreement (also known as a "clickthrough" agreement or clickwrap license) is a common type of agreement often used in connection with software licenses.  Such forms of agreement are mostly found on the Internet, as part of the installation process of many software packages, or in other circumstances where agreement is sought using electronic media.  The name "clickwrap" came from the use of "shrink wrap contracts" commonly used in boxed software purchases, which "contain a notice that by tearing open the shrinkwrap, the user assents to the software terms enclosed within".

Distal hereditary motor neuropathy type V: Distal hereditary motor neuropathy type V (dHMN V) is a particular type of neuropathic disorder.  In general, distal hereditary motor neuropathies affect the axons of distal motor neurons and are characterized by progressive weakness and atrophy of muscles of the extremities.  It is common for them to be called "spinal forms of Charcot-Marie-Tooth disease (CMT)", because the diseases are closely related in symptoms and genetic cause.  The diagnostic difference in these diseases is the presence of sensory loss in the extremities.  There are seven classifications of dHMNs, each defined by patterns of inheritance, age of onset, severity, and muscle groups involved.  Type V (sometimes notated as Type 5) is a disorder characterized by autosomal dominance, weakness of the upper limbs that is progressive and symmetrical, and atrophy of the small muscles of the hands.

Progressive parlay: A progressive parlay is a joint wager on multiple events, for example team sports or horse races.  Generally a progressive parlay involves a joint wager on four to twelve separate events.  Should all the selected bets win, the bettor receives a relatively large payout, because of the sizable odds against this happening.  However, unlike a regular parlay, if some of the individual bets lose, but most win, the bettor still wins, although with a much smaller payout.  Several sites use a schedule where the bettor can lose one bet on a 4-6 event progressive parlay, can lose up to two bets on a 7-9 event progressive parlay, and up to three bets on a 10-12 event progressive parlay.

Brazil–United States Treaty: The Brazil–United States Treaty was a military assistance agreement signed in 1952 in Rio de Janeiro between the two countries, with the goal of defending the Western Hemisphere.  Military relations between the United States and Brazil date back to World War II, when Brazil supported the Allied effort in the invasion of Italy in 1942.  Brazil provided troops for the invasion.  On January 3, 1952, The Brazilian government issued decree 30363 establishing new government regulations.  These new regulations allowed for the return of foreign capital that was invested in Brazil and profit remittances on that capital.  Shortly after, representatives from the United States and representatives from Brazil started to negotiate a bilateral military assistance agreement in Rio de Janeiro on January 3, 1952.  The document outlining the agreement between the two countries would be signed on March 15, 1952.  The agreement went into effect on May 19, 1952.  During the time of the negotiations, Major General Charles L. Mullins, Jr. negotiated a separate military plan with the Brazilian Government.  The plan was approved on March 14, 1952 by the Secretary of Defense Lovett.  In a private ceremony on March 15, 1952 United States Major General Mullins and Brazilian General Monteiro signed the military plan that outlined a common defense between the two nations.  The agreement allowed major weapons and training by the United States military to the Brazilian military.  This tenuous alliance governed the two nations bilateral ties during the events of the Cold War.  However, the alliance was short lived, and suffered several major blows between the two nations during the military coup in Brazil in 1964.  During this time the United States still provided military support and training to the side that supported the United States.

Vanguard Unionist Progressive Party: The Vanguard Unionist Progressive Party (VUPP), informally known as Ulster Vanguard, was a unionist political party which existed in Northern Ireland between 1972 and 1978.  Led by William Craig, the party emerged from a split in the Ulster Unionist Party (UUP) and was closely affiliated with several loyalist paramilitary groups.  The presence of features such as an honour guard and a common salute led opponents to accuse it of being fascist.  The party was set up in opposition to power sharing with Irish nationalist parties.  It opposed the Sunningdale Agreement and was involved in extra-parliamentary activity against the agreement.  However, in 1975, during discussions on the constitutional status of Northern Ireland in the constitutional convention, William Craig suggested the possibility of voluntary power sharing with the nationalist Social Democratic and Labour Party.  In consequence the party split, with dissenters forming the United Ulster Unionist Party.  Thereafter Vanguard declined and following poor results in the 1977 local government elections, Craig merged the remainder of Vanguard into the UUP in February 1978.
